She had a normal neuropsychological development. There was no family history of epilepsy. The physical examination was normal. Her seizures began with what it was described as <<weird feeling>> and then followed by automatism (chewing). This seizure lasted about 1 minute and 30 seconds. Our patient expressed total amnesia of her seizures. 1.5 Tesla MRI revealed a small round cyst in the right choroidal fissure of the temporal horn compressing the hippocampus. The signal intensity of the cyst was hyposignal T1 (Figure 1), hypersignal T2 (Figure 2), no restriction of apparent diffusion coefficient (ADC), identical to that of the cerebrospinal fluid (CSF). There was no peripheral contrast enhancement or surrounding edema (Figure 3). Based on the MR features, the presumptive diagnosis of a choroidal fissure cyst was made and seizures were medically controlled by Carbamazepine.", "gender": "Female" } ]

Recently, his symptoms progressively worsened to chronic hypoxemic respiratory failure. He required long-term supplemental oxygen therapy of 5 liters/minute by nasal cannula and high flows of up to 15 liters/minute during pulmonary rehabilitation. His pulmonary function tests revealed a markedly decreased forced vital capacity (FVC) and diffusing capacity of the lung for carbon monoxide (DLCO), which were only 35% and 34% of predicted, respectively. Computed tomography (CT) of the chest revealed diffuse ground glass opacities, punctate calcifications, and extensive subpleural cysts consistent with PAM (Figure 1). A prominent pulmonary trunk, right cardiac chamber dilation, and mild interventricular septum straightening suggested a component of pulmonary artery hypertension. Right heart catheterization confirmed pulmonary artery hypertension with normal cardiac output and cardiac index. Because of his progressive symptoms with significant oxygen requirements, he underwent bilateral lung transplantation.\nGross examination of the bilateral pneumonectomy specimens revealed enlarged lungs (right lung 1750 grams, left lung 1438 grams). The pink-tan pleural surfaces had multiple small plaque-like structures. The cut surfaces were pink-red and spongy with a gritty, sand-like texture (Figure 2). Hematoxylin- and eosin-stained sections revealed the characteristic diffuse intra-alveolar lamellar microliths (Figure 3). The background lung parenchyma showed interstitial fibrosis, numerous hemosiderin-laden macrophages, interstitial inflammation, and acute pleuritis.\nHis lung transplantation was complicated by intraoperative hemorrhage requiring >20 units of red cells and various other blood products. His hospital course was complicated by persistent leukocytosis and stenosis to the left mainstem bronchus, mucosal ischemia, and recurrent mucous plugging requiring repeated bronchoscopies. At 1 year post transplant, his pulmonary function tests revealed an improved FVC and DLCO of 50% and 76% of predicted, respectively. Since PAM has an autosomal pattern of inheritance, family screening was being considered for this patient.", "gender": "Male" } ]

In her family history, we noted that her sister has esophagus atresia associated with situs inversus and primary ciliary dyskinesia.\nThe first-trimester ultrasound screening at 12 weeks and 4 days of gestation revealed a hyperechoic aspect of the entire right lung, which led us to suspect a unilateral pulmonary pathology (Figure 1A, 1B). Nuchal translucency was measured at 0.9 mm for a cranio-caudal length at 62.5 mm. Regarding the precocity of this abnormality, the retained hypothesis was bronchial atresia, pulmonary sequestration, or CCAM.\nThe second-trimester test was based on the level of the maternal serum free-beta-hCG (1.04 multiples of the median [MoM]) and on alpha-fetoprotein (AFP) (0.90 MoM).\nAn ultrasound scan at 21 weeks described the same hyperechoic aspect of the entire right lung associated with discrete mediastinal and heart deviations with hydramnios. The patient was then referred to our department at 25 weeks of gestation. A hyperechoic right intra-pulmonary image, with left heart and aorta deviations, a right diaphragmatic dome eversion, and hydramnios, were confirmed. The color Doppler imaging showed homolateral pulmonary vessels vascularization. There was no Doppler flow evidence of a systemic arterial supply to the lesion. The left lung was compressed by mass effect (27x14 mm) (Figure 1C, 1D).\nAn amnio-drainage of 2500 ml of amniotic fluid and a karyotype were performed the same day. A few hours after puncture, a premature rupture of membranes was observed and the patient requested a medical pregnancy interruption. The biochemical analysis of amniotic fluid and the karyotype were normal (46 XY). Medical pregnancy interruption was accepted in accordance with the French laws and was performed uneventfully.\nOn autopsy, the fetus was discovered to be a male weighing 1550 g. The external examination revealed abdominal distension. On internal examination, all organs were in situ. The pulmonary parenchyma of the right lung lower lobe consisted in microcysts of variable size; most of them were 0.5 cm, inducing a major right lung hypertrophy (49.1 g vs. 5.5 g of the left lung, normal=27+-7 g). This tumor compressed and latero-deviated to the left the mediastinum (heart, thymus, left lung) and caused an eversion of the right diaphragmatic dome. On histology, right lungs showed multiple cysts relatively uniform in size, lined by stratified columnar epithelium, and having thin fibromuscular septa. All other visceral organs were congested but well-developed and revealed no anomalies. Based on these features, a pathological diagnosis of CCAM Stocker type 3 was confirmed (Figure 2A-2C).", "gender": "Male" } ]

Seven years before her visit, she delivered her first baby by Cesarean section due to progression failure. However, she succeeded in vaginal birth after a Cesarean delivery (VBAC) for her second delivery at another institution. She reported that during her second labor, she underwent numerous pelvic examinations because her labor did not progress smoothly. Finally, she underwent a vaginal delivery of a female infant weighing 3,580 g without applying vacuum or forceps. She did not visit at her scheduled postpartum examination after her second delivery, therefore, her perineal area was not explored after her vaginal birth.\nAfter her second birth, she experienced dyspareunia and her husband could not resume his sexual activity due to inability to achieve full penile insertion. Also, she reported the immediate leakage of semen after intercourse. In addition, her menstruation did not resume, but she attributed this phenomenon to breastfeeding. There was no abnormal finding in her vital signs and laboratory tests. However, it was hard to insert the speculum fully into her vagina because of her blind vagina canal. Also, her cervix could not be visualized by speculum examination. As a result of a thick transverse vaginal septum blocking her vaginal cavity, we could insert a speculum only 2 to 3 cm into her vagina (Fig. 1A). Transvaginal ultrasonography (Voluson 730 Expert, GE Medical Systems, Zipf, Austria) showed a transverse vaginal septum measuring 0.94 cm thick and a fluid-filled cavity beyond it (Fig. 1B). Vaginal adhesion was diagnosed and she was admitted for treatment of this rare condition.\nAfter hospitalization, prophylactic intravenous antibiotics (3rd-generation cephalosporin with metronidazole) were administered first. After the day of admission, the fluid in the obstructed vaginal cavity was aspirated and examined. This fluid was turbid and had a foul odor but no bacteria were found upon culture examination. With this aspiration, we excised the vaginal septum and sutured the remained edge of this septum to the vaginal wall using 2-0 Vicryl (Ethicon Inc., Somerville, NJ, USA) (Fig. 2). After the operation, we inserted Vaseline gauze into the vaginal cavity to prevent re-adhesion and hemorrhage. This packed gauze was maintained during the whole hospitalization period and changed every day. Antibiotics were administered intravenously for 5 days and she was discharged on day 5 after the operation. Three months following surgery, she noticed an improvement in her dyspareunia and resumed sexual activity. Pelvic examination revealed a well-maintained vaginal cavity.", "gender": "Female" } ]

The lump was slightly tender on palpation without interfering with finger flexion. Mass was noticed 3 months before without trauma history and kept growing since then.\nRoutine blood investigation was normal. Plain radiographs revealed a nonradiolucent object 5 x 2 mm in size, located in the region of the mass. A well-defined, avascular, mass was depicted in the MRI.\nPatient was scheduled to be operated for an excisional biopsy of a hand soft tissue tumor. Intraoperatively, a thick-wall cyst containing brown-colored fluid, a metallic object, and various particles resembling rusty products, was excised (Figure 2).\nAfter describing our findings to the patient, he recalled a long-forgotten incidence during World War II, 75 years ago: a \"superficial\" gunshot injury in the palmar aspect of the wrist near its crease. Ricochet of a bullet caused a wound that was healed with no complication, leaving a hardly noticed scar.\nHistological examination of the excised mass confirmed our suspicion. The residual foreign body was a bullet which, being deposited subcutaneously in the palm of the hand for more than 70 years, had been subjected to excessive corrosion in the biological environment and progressively isolated in a granulomatous tissue capsule.\nThe postoperative healing was uneventful. On the follow-up examinations at the 1st, 3rd, and 6th month, no sign of inflammation or recurrence has been noticed and hand function was unproblematic.

Muscle power was assessed as grade 3-4 out of 5 according to Medical Research Council (MRC) grading. Patient had paresthesia in both lower limbs in non-dermatomal distribution. Laboratory investigations including a hemogram, renal, liver and thyroid function tests were unremarkable. Serum vitamin B12 levels were normal.\nMagnetic resonance imaging (MRI) of the dorsolumbar spine performed with a 1.5T scanner (Signa Excite 1.5T, GE) revealed bulky lower lumbar cord and conus medullaris with high T2 signal. Multiple intradural extramedullary areas signal void were seen from Th6 to S1 level (Figure 1), more abundantly on the left side of Th10-Th12, causing rightward displacement of the lower part of the spinal cord. Spinal cord exhibited intense, relatively homogenous enhancement after intravenous gadolinium injection (Figure 2). Subsequent spinal computed tomography angiography (CTA) was performed with a 16-slice scanner (Philips Brilliance 16, Philips Medical Systems) with nonionic iodinated contrast agent (Iohexol, 350 mg/mL) at dose of 2 mL/kg injected into the antecubital vein through pressure injector at a rate of 4 mL/sec with bolus tracking, with ROI placed over the abdominal aorta (scanning parameters: increment 1.0 mm, reconstruction interval 0.75 mm, slice thickness 2.0 mm, pitch 1.188, rotation time 0.75s, kVp 120, mA 200) CTA revealed an intradural extramedullary arteriovenous malformation (AVM) from Th10 to Th12 level (Figure 3) supplied by a branch of a great radicular artery (artery of Adamkiewicz). In our case it originated from the abdominal aorta on the left side and ran subcostally, entering the spinal canal through the Th12-L1 intervertebral foramen (Figures 4-6). The AVM drained into the right internal iliac vein through an elongated, tortuous venous channel. Adiagnosis of intradural perimedullary AVM with congestive myelopathy (Foix-Alajouanine syndrome) was made based on the findings.\nThe patient underwent digital subtraction angiography (DSA) - guided embolization of the AVM with 20-percent cyanoacrylate glue. Immediate postoperative period was uneventful. Postoperatively, over a period of 8 months of regular physiotherapy, the patient showed gradual mild improvement of symptoms, with muscle power of 3 to 4 acc. to MRC grading in both lower limbs.

At 1 year of age, he presented with daily obstructive symptoms of distention and bloating. He suffered from three episodes of enterocolitis, each requiring hospital admission. At an outside hospital, he underwent an examination under anesthesia and a full thickness rectal biopsy with findings of an intact dentate line, no anastomotic stricture, and a palpable Soave cuff on the anterior rectal wall only. His rectal biopsy showed ganglion cells, normal size nerve fibers, normal anticholinesterase reaction, a normal calretinin staining pattern, and his contrast study was felt to be normal. The patient also underwent colonic manometry testing which showed diffuse colonic dysmotility. Based on this result, an ileostomy was recommended.\nThereafter, the patient thrived. The patient then returned for a planned repeat manometry study 6 months later which now showed normal motility, and the recommendation was to close the ileostomy. Prior to closing the ileostomy, the family sought a second opinion.\n Our review of the post pull-through contrast enema ( Fig. 1 ) came to a different conclusion. We felt the study showed a 180-degree twist in the distal pull-through ( Fig. 1 ). This was demonstrated by the shift in the antimesenteric border of the colon. We also felt that the twist was intermittent since the contrast study did not demonstrate bowel dilatation proximal to the twist. Since this patient had a previous Soave pull-through, it was also important to note the presence of presacral space widening ( Fig. 2 ), which could be indicative of a Soave cuff; however, this was not evident on the physical exam. Our repeat examination under anesthesia and rectal biopsy confirmed the findings from the outside hospital of no circumferential Soave cuff; however, we were unable to pass a digit or a Foley catheter freely into the pelvis. Given the recurrent obstructive symptoms that occurred prior to the ileostomy and the concerns on the contrast study and exam, we offered the patient a reoperation. We performed a Swenson type redo transanal only pull-through and upon transanal mobilization the distal pull-through was noted to have a 180-degree twist, with the mesentery on the anterior side when it should have been either medial or posterior ( Fig. 3 ). We untwisted the pull-through and redid the coloanal anastomosis and confirmed no twist by freely passing the foley catheter into the pelvis. The patient did well postoperatively and was discharged home on postoperative day 4. He was seen for a follow-up at 1 month, which showed a well-healed pull-through with no anastomotic stricture and his ileostomy was closed.

At 8 days of life, he developed diffuse cutaneous pustules starting in the groin and then spreading across the body. The lesions failed to improve with topical antibiotics necessitating hospitalization at age 44 days for intravenous (iv) antibiotics and incision and drainage (I&D). He was diagnosed with infantile eczema and a superimposed bacterial infection; wound cultures were positive for Staphylococcus aureus.\nAt 4 months of age, the patient was again admitted to the hospital with a recurrent abscess requiring I&D and iv antibiotics. Throughout his early childhood he continued to develop recurrent skin and soft tissue infections almost monthly and usually without fevers, including at 4 years of age when he had another I&D of a facial abscess with cultures growing methicillin resistant Staphylococcus aureus. At age 5 he was admitted to the hospital with pneumonia complicated by a parapneumonic effusion and multiple cavitary lung lesions (Figure 1). He was treated with drainage of the lung nodules and prolonged iv antibiotics.\nGiven his recurrent infections at an early age of onset requiring repeated hospitalizations and iv treatments, the immunology service was consulted. The patient had several immune evaluations at age 2 and 4 that were normal and included immunoglobulin levels with undetectable IgE and normal lymphocyte subsets, CD11 and CD18 expression, nitroblue tetrazolium testing and myeloperoxidase staining.\nAt 7 years of age, the patient was admitted to the hospital with superinfection of his eczema lesions and his IgE was then found to be elevated at 4,409 kU/L (normal 0-63 kU/L). Given his history of recurrent staphylococcal infections and elevated IgE, AD-HIES was suspected. A de novo, heterozygous missense mutation in STAT3 (c.1934T>A, p.L645Q) was detected (Figure 2A). This novel mutation is located in the SH2 domain, adjacent to amino acids previously reported to contain STAT3 mutations associated with AD-HIES. It is not reported in publically available databases.\nThis mutation changes a polar glutamine for a non-polar leucine. Reduction of transcriptional activity of STAT3 p.L645Q to 85% of wild-type was confirmed using a luciferase assay (Figure 2B). The patient also had decreased CD3+CD4+ T cells expressing IL-17 (Figure 2C). Furthermore, STAT3 phosphorylation in patient-derived cells was impaired in response to cytokine stimulation (Figure 3), which has been reported in patients with AD-HIES and STAT3 mutations in the SH2 domain.\nThe patient did not have a history of mucocutaneous candidiasis. He did have eosinophilia (10.7%, 560 cells/muL), a common finding in AD-HIES. His peak serum IgE has been 10,665 kU/L. At 14 years of age, the patient sustained a non-displaced fracture in his ankle following a ground level fall. Bone densitometry showed osteopenia. He did not manifest other non-immunologic features of AD-HIES such as coarse facies, high-arched palate, scoliosis or joint hyper-extensibility, although he was noted to have retained primary upper incisors. He did have two separate and resolving episodes of facial nerve palsy at age 5 and 15 years not clearly associated with a viral infection.\nAfter the diagnosis of AD-HIES, the patient was started on prophylactic cephalexin but continued to struggle with recurrent abscesses. After his response to pneumococcal vaccination was judged insufficient, his prophylactic antibiotic was changed to levofloxacin and he was started on immunoglobulin replacement therapy.

We infused urokinase every 12 h up to 4 doses instead of performing a single injection, and the patient was stable during the process. On postoperative day 3, head CT showed a residual clot (10 mL on the right and 2 mL on the left side) and the patient was extubated (Figure 1E and F). Human albumin and furosemide were administered to control ICP and cerebral edema. The patient's pneumonia continued to worsen after the operation, requiring assisted ventilation.

The patient complained of pressure-like, intermittent chest pain, 8-10 in intensity, located on the left-sided chest and radiated to the left arm and shoulder. Each episode had a duration of 30 min with 5 min between each episode. Initially, the pain was exacerbated upon physical activity and alleviated with rest, however, a few hours before presentation to the Emergency Room, the patient also experienced pain at rest.\nHe had not been compliant with his medication regimen for the last two years before the presentation and he chose to treat his medical conditions exclusively with ginger.\nPertinent negatives included diaphoresis, orthopnea, paroxysmal nocturnal dyspnea, lower extremity edema, dizziness, and syncopal episodes. His family history was remarkable for his father with cardiac disease status post stents placement.\nIn the Emergency Room, the patient was found to be hypertensive with a blood pressure of 154/83 mmHg, non-tachycardic or tachypneic, and saturating 97% on room air. The initial troponin I level was 0.12 [<0.5 ng/ml], but the follow-up troponin I was 0.51 [<0.5 ng/ml]. Initial ECG showed sinus rhythm, first-degree AV block, incomplete right bundle branch block, biphasic T-wave inversion in V2 and V3, and T-wave inversion in anterolateral leads.\nIn the setting of the patient's clinical presentation associated with troponin leakage and ECG changes concerning for ischemia, he was started on full acute coronary syndrome (ACS) protocol including loading dose of aspirin, and clopidogrel, therapeutic anticoagulation, and statin therapy along with monitoring ECG changes and troponin I levels.\nThe following day, the patient remained hemodynamically stable, and the chest pain was resolved. However, the repeat troponin I level was 0.80 [<0.5 ng/ml], and follow-up ECG showed sinus bradycardia with a heart rate of 55 beats per min with first-degree A-V block, incomplete right bundle branch block, and biphasic T waves in V2 and V3 which in that clinical setting was consistent with Type-A T waves seen in Wellens syndrome (Fig. 1). An echocardiogram was also performed, and it revealed a left ventricular ejection fraction of 50-55% and mildly hypokinetic changes on the apical septal and apical anterior segments.\nThe patient was taken to the catheterization laboratory for left heart catheterization, coronary angiography, and left ventriculography. During the intervention, it was found that the LAD had a proximal to mid stent and a distal stent in place. There was proximal 90% in-stent restenosis at the proximal edge of the first stent. There was also a 90% in-stent restenosis at the proximal edge of the second stent into the mid-segment, which was a tubular lesion. Also, there was a distal 70% discrete stenosis in the distal LAD.\nBecause of the above findings, a total of three stents were placed. The first stent was placed in the mid to distal LAD to cover the second 90% lesion. The second stent was placed to cover the proximal lesion and was placed at the proximal edge of the previous stent. A third stent was placed in the distal LAD at the level of the distal 70% discrete stenosis. The repeat angiographic shots showed excellent results with no residual angiographic stenosis and no dissection, perforation, or complications.\nFurther recommendations included aggressive guideline-directed medical therapy for coronary artery disease, including dual-antiplatelet therapy with aspirin and clopidogrel for minimally one year, a beta-blocker, and a statin.

His previous symptoms had completely resolved and he moved to the United States from Nepal one year prior to the hospital admission.\nOn physical examination, the patient was afebrile, hemodynamically stable with a generalized cachectic appearance and diffuse rhonchi bilaterally on pulmonary auscultation. His labs were notable for a normal leukocyte count, a hemoglobin of 11.7 g/dL, and normal chemistries. The chest x-ray, Fig. 1, had a lucency in the left suprahilar region and bilateral peribronchial thickening of the upper lobes. A follow up CT scan, Fig. 2, showed multiple cavitary lesions at the superior segment of the left lower lobe.\nOn hospitalization day 2, a microscopic smear of his sputum showed many acid-fast bacilli that was later identify in cultures as Mycobacterium tuberculosis complex. He was started on a 5-drug regimen with rifampin, isoniazid, pyrazinamide, ethambutol and moxifloxacin due to his prior history of possible resistant TB. He continued to have persistent hemoptysis and worsening anemia requiring a transfusion due tachycardia and dyspnea, suggesting massive hemoptysis. Four days after the anti-tuberculosis medication was initiated, he developed respiratory distress and was transferred to the medical intensive care unit and was placed on non-invasive positive pressure ventilation but did not improve.

Given his active tuberculosis, difficulty with oxygenation, and multiple cavitary lesions, the decision was made to proceed with left lower lobectomy. On gross examination, the lobe of lung was severely congested weighing 645 g (normal weight of a complete left lung: 395 g).

Numerous cavities developed in relation to necrotizing granulomas with suppuration and hemorrhage, Fig. 3D. Round foreign particles were deposited in the arterial lumina, consistent with a prior embolization procedure. Intra-alveolar hemorrhage emerged after bleeding into the cavitating granulomas due to destruction of vessel walls, Fig. 3E and F. Few acid-fast organisms consistent with L-shaped mycobacteria were identified on FITE stain, Fig. 3G-I.

We used 18-month-old BALB/cBy mice (obtained from the National Institute on Aging) orthotopically implanted with 4T1 breast cancer cells as a model to study the effect of exercise on stromal cell populations. The 4T1 breast cancer cell line in mice is highly invasive, with the ability to metastasize to lungs, brain, liver, bone, lymph nodes, and blood, similar to triple negative invasive breast cancer in women.\nMice were randomly selected, with 15 mice in the running group. Runners were given access to free running wheels in individual cages as previously described. We monitored the running activity continuously for 60 days. 4T1 cells (ATCC, Manassas, VA), cultured under standard laboratory conditions, were injected at a concentration of 1x104 cells into the 4th mammary fat pad of each mouse. Mice were allowed to run another 30 days when the experiment ended. Running wheels (measuring 15.5 cm by diameter) transmitted electronic signals wirelessly to a monitoring hub (Med Associates ENV-044, Vermont) and raw data were exported to Microsoft Excel for processing. The distance ran by each mouse was calculated as (3.14x15.5 cmxnumber of revolutions)/(100 cm per mx1,000 m per km). Mice were housed in a standard rodent room within a specific pathogen-free (SPF) barrier facility with 12-hour light and dark cycles. Ambient temperature in the room was kept at 70-74 F. Mice were fed standard rodent chow (5,053; Picolab, Richmond, IN) and water ad libitum. The experimental protocol was reviewed and approved by the Institutional Animal Care and Use Committee at the University of Washington, Seattle.\nAt 30 days post-tumor cell injection, mice were euthanized by CO2 asphyxiation. Carcasses and mammary tumors were weighed to obtain tumor burden, defined as tumor weight normalized to carcass weight. The breast tumor from each mouse was fixed in 10% neutral-buffered formalin. Immunohistochemistry was performed as previously described using paraffin-embedded tumor sections. Primary antibodies to specific markers were incubated at 1:50 for 1 hour. Sections were blocked in 15% goat/5% mouse serum. BGA rat secondary antibodies (Jackson ImmunoResearch Labs Inc., West Grove, PA, USA) were used and incubated at 1:200 for 30 min and slides then counterstained with hematoxylin. Digital images were captured using a Nikon Eclipse E400 bright field microscope (Nikon Corporation, Tokyo, Japan) attached with a Nikon Coolpix 995, digital camera (Nikon Corporation, Tokyo, Japan; 3.3 megapixels, resolution 2,048x1,536 pixels). Five random images at 60x magnification were captured per tumor sample under blinded conditions and saved in JPG (Joint Photographic Experts Group) format. The number of labeled cells was also determined blindly and independently by two co-authors of this paper (CPB and WL) by counting positive cells in a grid of eight squares encompassing the entire plane of view at 20x magnification per slide using five random field views. The labeling index was calculated as the average percentage of stained cells relative to unstained cells. Student's t-test was used to detect significant differences between groups.\nDuring the tumor progression phase of 4T1 breast cancer in old BALB/c mice, we observed significant differences in labeling for F4/80, a marker for mouse macrophages, and CD34, a marker for vascular endothelial cells, in primary tumors from mice that ran higher average distances compared to mice that ran lower average distances, p<=0.05, N=2, from four mice (Table 1). It can be seen that macrophages are much less frequent in a tumor from a long-distance runner (Fig. 1a) compared to a tumor from a short-distance runner (Fig. 1b). The decrease in CD34 labeling in a long-distance runner (Fig. 1c) compared to a short-distance runner (Fig. 1d) suggests that increased running distance was also associated with decreased vascularization. There were no significant correlations between running distance and labeling for cell proliferation (Ki-67) or apoptosis (Caspase 3) in primary tumors (Table 1), suggesting that exercise training might be targeting stromal cell populations. Even though pre-tumor running was associated with an anti-tumor effect in a distance dependent manner, no correlation was seen between tumor burden and running distance during the tumor progression period. It is possible that the rapid and aggressive tumor growth may have overwhelmed any anti-tumor effects by suppressed stromal cells. However, there were no significant correlations between distance ran before tumor injection and labeling for F4/80 and CD34 as well as for Ki67 and Caspase 3 in primary tumors collected at the termination of the study (data not shown) suggesting other unknown mechanisms are likely responsible for the antitumor effects of pre-tumor running.\nThese observations suggest that immunohistochemistry can be used to monitor stromal cell populations in tumors from old mice under exercise conditions, and further support the concept of using old mice for modeling in preclinical cancer studies.", "gender": "Male" } ]

The patient claimed to have no history of smoking, allergies or occupational exposure to noxious agents. Physical examination revealed coarse breathing sounds with inspiratory crackle extending over the whole of the both lung fields. However, the results of blood analysis were normal.\nChest radiographs demonstrated the presence of bilateral, diffuse, reticulonodular densities in both lungs (Fig. 1A). Thin-section CT scan showed diffusely distributed mosaic pattern of inhomogeneous attenuation extending over the entirety of lung zones, without zonal predominance. There was no difference in the extent of mosaic attenuation between inspiratory (Fig. 1B) and expiratory thin-section CT scans (Fig. 1C). As compared with more highly attenuated areas of the lung, however, the caliber and number of pulmonary vessels in areas of the lower attenuation were reduced. There were several foci of bronchial wall thickening, and these were more frequently found in areas of lower attenuation. In the right lower paratracheal area and subcarinal area, the presence of several small lymph nodes less than 1 cm in short axis diameter was noted.\nFlexible fiberoptic bronchoscopy revealed no remarkable finding, though transbronchial multiple biopsies obtained from the right anterior segmental bronchus showed some lymphocytic infiltration. Cytologic analysis showed that the composition of bronchoalveolar lavage fluid was 45% lymphocytes, 1% eosinophils, and 54% macrophages. Open lung biopsy was performed in areas of both higher and lower attenuation. Histologic examination disclosed focal collections of lymphoid cells around bronchioles and extension of lymphoma cells from bronchiolar epithelium toward alveolar space. Immunocytochemically, the neoplastic cells reacted positively for CD 20 antigen and were focally positive for UCHL 1 antigen. Monoclonal antibody against cytokeratin indicated multiple lymphoepithelial lesions. The histologic diagnosis was consistent with low grade marginal zone B-cell lymphoma originating in BALT.", "gender": "Unknown" } ]

She complained of a constant cough and dyspnea on exertion starting a year before referral. Neither antibiotics nor inhaled corticosteroids improved the patient's condition and further investigations were performed at another hospital. High resolution computed tomography (HRCT) showed bilateral changes typical for PAP with not a classical crazy paving pattern (Fig. 1). A surgical biopsy revealed alveoli filled with a granular proteinaceous material, strongly eosinophilic on hematoxylin-and eosin staining (HE) and positive with the periodic acid-Schiff stain and diastase-resistant (PAS + D), which is considered characteristic for PAP (Fig. 2). Blood assays showed elevated high levels of GM-CSF antibodies. There was no suspicion of rheumatological or hematological diseases. Based on these results a diagnosis of aPAP was confirmed and the patient was referred for treatment.\nAt the time of referral to our department the patient reported regular cough and dyspnea upon physical exertion. She had no weight loss, fever or recurrent infections. She had no family history of lung disease and was a never-smoker. Physical examination was normal. Pulmonary function tests revealed a forced expiratory volume in one second (FEV1) of 2.23 L (62%), forced vital capacity (FVC) of 2.64 L (70%), total lung capacity (TLC) of 72% and carbon monoxide diffusing capacity (DLCO) of 54% of predicted.

After evaluation of the patient's history she was treated with WLL without improvement. After the third WLL, supporting treatment with inhaled GM-SCF was therefore initiated. Firstly, sargramostim (Leukine; Sanofi-Aventis; 250 mug x 2 per week) was used for a short period, but when molgramostim became available in a named patient program, it was decided to change the inhalations to rhGM-CSF - molgramostim (Molgradex; Savara Pharmaceuticals). We chose the following treatment protocol: 300 mug daily in seven days repeated with seven days of pause. After seven months, the therapy was intensified to 300 mug daily. HRCT one year after the treatment did not reveal significant regression of the crazy-paving pattern. Nevertheless, there was a significant clinical improvement with remission of all her symptoms, as well as in her pulmonary function, which almost normalized. After 17 months of molgramostim inhalations her FEV1 was 2.58 (79%), FVC 3.05 (79%), TLC 77% and DLCO 74% of predicted. No adverse effects of the molgramostim inhalations were observed.

She has had a history of headaches for over 20 years with one or two attacks per year described as a throbbing or swelling pain in the occipital region or even the whole brain with an intensity of 6 to 9/10. There was no significant aura before the attack. The headache attack was accompanied by numbness and coldness of the painful area and stiffness of the neck, and nausea and vomiting without photophobia or phonophobia. At worst, she could not take in any food or medicine because of vomiting. The headache usually lasted for 5-6 days and could last up to 15 days, and was slightly relieved by ibuprofen and flunarizine. On the fourth day of this attack, she suddenly suffered an inability to walk lasting for 1 day. She could stand on her own without any dizziness. However, every time she tried to start walking, she felt stiffness in both lower extremities and was unable to step and walk, but could only maintain an upright position. And, it did not change with prolonged standing time. In addition, no movement other than walking was affected. When she was lying down, the movement of both lower extremities was not restricted and she could raise and lower her legs and move them in any direction at will. The same symptom happened once 6 years ago, and it resolved on its own after lasting for 1 h.\nThe physical examination and vital signs were unremarkable, and the neurologic examination was normal. The patient showed a task-specific lower limbs dystonia, characterized by the appearance of sustained dystonic extension of both knees induced by stepping or walking attempts. Magnetic resonance imaging (MRI) scan of the brain showed no significant abnormalities (Figure 1). The patient underwent a lumbar puncture, the cerebrospinal fluid (CSF) pressure was 125 mm H2O (normal range: 80-180 mmH2O), and the biochemistry and cytology of the CSF were negative. Her blood tests were regular, including routine blood work, liver function, kidney function, ions, D-dimer, and markers of myocardial damage. The contrast transcranial doppler echocardiography (cTCD) showed a latent and massive right-to-left shunt (RLS), that was, more than 25 microbubbles were detected using insonation of the left middle cerebral artery (LMCA) after the release of the Valsalva maneuver (Figure 2). No microbubble was seen in the resting state. Right heart contrast echocardiography confirmed the result. Her echocardiography revealed no abnormalities in the structure and function of the heart at rest.\nFinally, the patient was diagnosed with migraine and dystonia of the lower extremities induced by it. The cTCD and right heart contrast echocardiography suggested that she had a patent foramen ovale (PFO). Transesophageal echocardiography (TEE) was required to clarify her heart condition further. The patient's headache lasted for 12 days and was relieved with oral ibuprofen (two capsules per day) and flunarizine (10 mg per day). The symptom of the inability to walk cleared spontaneously staying for 1 day, and she was capable of walking slowly and awkwardly during the consultation. Other than medicines for headaches, no additional treatment was given, similar to the situations 6 years ago. Considering the presence of PFO, we recommended she avoid actions that would increase chest pressure, such as diving, violent coughing, and strenuous exercise, which would be of considerable benefit for preventing her headaches. At a follow-up 6 months after the attack, the patient had no episodes of headache and walking difficulty. Unfortunately, owing to financial problems, the patient did not undergo a relevant genetic test, making it difficult to explore the etiology of her condition further.", "gender": "Female" } ]

The patient underwent surgical staging 4 months later with total abdominal hysterectomy, bilateral salpingo-oophorectomy, pelvic lymphadenectomy, and omentectomy. Out of the total 21 resected lymph nodes, one was involved with cancer and the carcinoma was staged at T3aN1M0, Stage 3.\nFollowing surgical staging and tumor resection, the patient underwent chemotherapy with three cycles of carboplatin and paclitaxel at 21-day intervals, followed by pelvic radiotherapy (planned total dose 5040 cGy), and finally three additional cycles of carboplatin and paclitaxel. Initial doses of carboplatin were targeted at 750 mg/cycle (AUC = 6) and paclitaxel at 175 mg/m2. Because of extended duration radiation related Grade 3 colitis, radiation therapy was stopped after receipt of 1980 cGy. Patient then underwent 3 more cycles (cycles 4-6) of chemotherapy with carboplatin and paclitaxel. The total cumulative dose of paclitaxel was 1511 mg and that of carboplatin was 4312 mg.\nPrior to beginning chemotherapy, the patient had normal blood counts except for a mild iron deficiency anemia (hemoglobin 11.2 gm/dL, white blood cell count 7200/mm3, and platelets 168,000/mm3). Her platelet count after completion of radiation therapy was 120,000-140,000/mm3, with mild anemia and a normal white blood cell count. After receiving the sixth and final dose of chemotherapy, her platelet count fell to 80,000/mm3 and did not recover.\nSix months after last cycle of chemotherapy, patient was hospitalized thrice over a period of two months with high grade fevers. She had worsening anemia and thrombocytopenia during this period which prompted a bone marrow biopsy. This revealed a hypercellular marrow with overall 5% myeloblasts with megaloblastic changes in the red cells and myeloid series and normal appearing megakaryocytes (Figures 1 -3). The peripheral blood showed marked anisocytosis with moderate normocytic normochromic anemia and left shifted myeloid series and thrombocytopenia (Figure 4). The findings were consistent with treatment related myelodysplastic syndrome with refractory anemia and excess blasts. Karyotyping revealed abnormal female karyotype: 45,XX,add(3)(p13),del(3)(q23q25),-5,add(5)(q13),add(7)(q11.2),der(17)t(5,17)(q15;q25).\nWithin six weeks of the diagnosis of myelodysplasia, she had progressed to acute leukemia. Initial lab work revealed leukocytosis up to 76000 with 22% blasts; anemia with Hb 6.4 g/dL; and thrombocytopenia with counts of 15,000/mm3. She was given a provisional diagnosis of therapy related AML. A bone marrow biopsy revealed hypercellular marrow with 29% of cells blasts. The blasts exhibited both myeloid and monocytic features and a diagnosis of acute myelomonocytic leukemia (AML; FAB classification: M4) was made. Peripheral smear also showed persistent leukocytosis with blasts >27% along with anemia and thrombocytopenia which eventually required transfusions.\nPatient was offered treatment options including chemotherapy for AML and then possible stem cell transplant but decided not to pursue chemotherapy and opted for supportive treatment.

There was no sign of viscera metastases. Core biopsy showed poorly differentiated metastatic breast carcinoma that was estrogen receptor positive, progesterone receptor negative, and strongly human epidermal growth factor receptor (HER2) positive (3+).\nPalliative chemotherapy with docetaxel (75 mg/m2), cisplatin (75 mg/m2), and trastuzumab (6 mg/kg, first treatment using 8 mg/kg) was started for 6 cycles, followed by two cycles of docetaxel and trastuzumab treatment. After the treatment, CT scanning showed that all the lymph nodes disappeared and symptoms of pain all over the body had also been relieved. Nevertheless, the patient's platelet count decreased to 48 x 109/L before the 9th treatment. Docetaxel-induced bone marrow suppression was suspected, and trastuzumab and capecitabine (1.5 g, bid, 1-14 d) were used for the 9th treatment. Meanwhile, recombinant human thrombopoietin (TPO) was injected to increase the platelet level. As anticipated, the platelet count returned to normal in 3 days.\nBefore the 10th treatment, the platelet count of the patient was 99 x 109/L (Figure 1a). Trastuzumab and capecitabine were used again for the 10th treatment. The patient felt tiredness and nausea and all-over body petechiae, and gums bleeding occurred after a 6 h trastuzumab infusion. Blood examination showed that the platelet count was 1 x 109/L. Blood smear examination showed severe thrombocytopenia with no schistocytes, spherocytes, clumps, and giant platelets. Bone marrow biopsy showed normal megakaryocytopoiesis without signs of tumor infiltration. Heparin had never been used and other causes of thrombocytopenia such as disseminated intravascular coagulation, thrombotic thrombocytopenic purpura, hereditary thrombocytopenia, and hemolysis were excluded because of her normal clotting, D-dimers, immunoglobulins, hemoglobin, renal function, bilirubin, and lactate dehydrogenase as well as lack of schistocytes. After consultation with the hematologist, drug-induced thrombocytopenia was suspected. Given the treatment effect of trastuzumab, capecitabine was withdrawn and 3 weekly trastuzumab was maintained.

In 2015, she was diagnosed twice with a solitary \"in-transit\" metastasis on the right leg for which excision was performed. At the end of 2015, a third solitary in-transit metastasis on the right leg was diagnosed, which was also excised, unfortunately without achieving histological radicality. Due to the persistent recurrences of metastatic disease, BRAF mutation was analysed and showed BRAF V600 positivity of the tumour. At that time, ultrasound showed a viable, intrauterine monochorionic-diamniotic twin pregnancy with a gestational age of 65/7 weeks. Intralesional chemotherapy was indicated due to the non-radical excision, but was deemed unsafe considering the early pregnancy. Instead, re-excision under local field block anaesthetic was performed. One month later, another two in-transit metastases on the right leg were excised.\nTwo months after the last excision, she presented to the emergency room with abdominal pain, persistent vomiting, and constipation. Ultrasound and MRI showed an intussusception of the jejunum over a length of 10-15 cm, para-aortal lymphadenopathy, and a viable pregnancy of 18 weeks. She underwent a laparotomy, confirming the diagnosis of intussusception. The affected jejunum was resected. Histologic examination of the resected bowel and a sample of the tumours palpable in the mesentery showed metastatic melanoma. A PET/CT scan at 216/7 weeks of gestation (low-dose 18F-FDG, with bladder catheter) showed multiple cutaneous and breast metastases. An MRI of the brain showed solitary metastases in the temporal lobe. Due to the high tumour load, non-viable gestational age with the wish to continue her pregnancy and a BRAF V600 pathogenic mutation of the tumour, the patient was started on vemurafenib (twice a day, 960 mg) at a gestational age of 225/7 weeks after extensive counselling. At that time, both fetuses had normal weight on ultrasound, and no congenital anomalies were seen. Twelve days after commencing vemurafenib, our patient reported some mild skin toxicity, starting with some erythema on the face and back. The skin lesions rapidly worsened within 9 days with profound erythema and blisters on the neck, thorax, and arms covering over 70% of her body surface area, and purulent discharge from the eyes. Following this rapid progression of skin toxicity, our patient was admitted to the hospital and vemurafenib was immediately discontinued. Skin biopsy showed toxic epidermal necrolysis (TEN).\nThe patient was admitted to the intensive care unit the next day, where she was sedated and intubated for pain management. She required extensive rehydration due to significant insensible loss. In addition, betamethasone for fetal lung maturation was given in anticipation of preterm delivery because of maternal deterioration. There were no signs of spontaneous preterm labour or intrauterine infection.

On arrival, she was found to be in labour and she delivered both children while still sedated (first baby by forceps extraction, second baby by breech extraction). Two baby boys were born with birth weights within the normal range; one with a birth weight of 950 g and an APGAR score of 2 and 3 at respectively 5 and 10 min and one with a birth weight of 900 g and an APGAR score of 6 at 5 and 10 min. Both children were admitted to the NICU.\nDuring the burn centre hospitalization, some re-epithelialization occurred, but unfortunately, the patient suffered several episodes of wound infection which delayed the wound healing. Initial topical treatment with alginate dressing was replaced by silver sulphadiazine upon diagnosis of pseudomonas wound infection. The mucosal lesions in the mouth caused significant bleeding. Oral rinsing with povidone solutions seemed effective but caused a iodide intoxication with hypothyroidism and a high anion gap acidosis. Corneal erosions and conjunctival adhesions were treated intensively in collaboration with the ophthalmologist. The first weeks were characterized by fluid loss and oedema, and pleural effusion complicated weaning from the ventilator. Once stabilized, the patient responded well to diuretics. Renal function remained normal throughout the burn centre stay. After delivery, oncological treatment with pembrolizumab would have been indicated once the TEN had improved and clinical condition improved. However, 53 days after delivery and 78 days after the start of vemurafenib, and before our patient could start with pembrolizumab, she died of an intracranial haemorrhage due to metastatic disease.\nBoth children were discharged from NICU to special nursery care 59 days after delivery and were discharged home 95 days after delivery. At a corrected age of 15 months, physical examination showed no abnormalities. Mental development was assessed using the Bayley Scales of Infant and Toddler Development (BSID).

The superior mesenteric artery (SMA) and superior mesenteric vein (SMV) were visualized with the SMA lying to the left of the SMV with normal anatomic alignment [Figure 1]. No large solid or cystic masses were seen.\nA standard barium single contrast upper gastrointestinal (UGI) series was performed with the contrast entering the antrum and duodenal bulb. The proximal duodenum and descending duodenum were markedly dilated in caliber with apparent tapering of the third part of the duodenum. There was an abrupt cutoff with no contrast extending beyond approximately the mid abdomen [Figure 2]. Delayed images were obtained while the patient was supine with contrast never extending beyond the third portion of the duodenum [Figure 3].\nPatient was subsequently placed prone for several minutes with eventual slight transit of contrast [Figure 4]. Thirty minute delayed prone images demonstrated contrast in the proximal small bowel, however proximal duodenum remained markedly dilated and contrast/debris filled [Figure 5]. Additionally delayed overhead images demonstrated contrast extending to the distal small bowel after patient had been upright for greater than 30 minutes [Figure 6]. Markedly dilated proximal duodenum with abrupt cutoff in the third portion of the duodenum raised concern for a questionable mass like positionally dependent extrinsic compression of the third portion of the duodenum.\nA subsequent computed tomography (CT) of the abdomen and pelvis was performed with oral and intravenous contrast.

She had congenital erythematous and scar lesions on the face, back, and upper and lower extremities (Figure 1). An examination revealed a slight elevation in hepatic transaminases, thrombocytopenia, and mild cardiac failure. No heart blockage was detected. The serological examination of the neonate showed elevated anti-SSA/Ro (281 U/mL) and anti-SSB/La antibodies ( 1000 U/mL).

The patient underwent resection by an otolaryngologist, and the tumor was found within the orbit, with extension into the frontal sinus, posterior orbital wall, ethmoid sinus, and inferiorly into the superior edge of the medial maxillary wall. The orbital wall was reconstructed using titanium mesh embedded within a polyethylene implant, and, in 2012, a free flap was performed, followed by radiation and left eye enucleation.\nThe patient recovered from surgery but, over the next few years, continued to develop additional primary KCs at sites separate from the location of reconstruction, including SCCs on the right submental neck, right forehead, and left ear. Acitretin was taken for 2 months for chemoprevention of KC but was discontinued in early 2016 because of poor wound healing. One month later, the patient had significant pain and a small erosion of his left medial orbital rim, which he attributed to chafing from the bridge of his eyeglasses. Given concern for possible SCC recurrence with supratrochlear nerve involvement, a shave biopsy was obtained at the site of the patient's pain (Fig 1, A). There was a white linear plaque lateral to the biopsy site. Initially, this clinically appeared to be lichenification caused by recurrent friction from the patient's eye patch. The biopsy performed to rule out recurrent SCC showed spongiotic psoriasiform dermatitis likely of multifactorial etiology from past radiation therapy and erosive pustular dermatosis. He soon developed a 2-cm ulcer with clear exposure of the implant (Fig 1, B). Continued expansion of the ulcer while awaiting surgical resection raised concern for infection, recurrent SCC (assuming sampling error of the previous biopsy), poor wound healing secondary to prior usage of acitretin, and inflammatory dermatoses such as pyoderma gangrenosum or a variant of erosive pustular dermatosis (Fig 1, C).

[ { "age": 19, "case_id": "PMC9380446_01", "case_text": "Efforts in domestic HIV prevention prioritize working with disproportionately affected groups, including youth as a priority group, to meet national goals to reduce new HIV infections, increase engagement of infected persons in care, and decrease HIV-related health disparities. National and local data suggest that among youth aged 13-24, Black/African American and Hispanic/Latino youth carry the largest burden of disease, especially during the time of this study (see Figure 1a). For example in 2015, Black youth only made up 14% of the 13-19 year old population in the U.S., yet these youth accounted for 64% of new HIV diagnoses. The causes of these disparities are multi-level, including the role of mental health and emotion regulation in youth's sexual decision making and neighborhood-level poverty and disadvantage. These data underscore that research and program efforts with racial/ethnic minority youth, including individual and macro-level approaches, are urgently needed for domestic HIV prevention.\nTo facilitate routine HIV/STI testing and treatment and access for youth, all 50 states and the District of Columbia have laws in place that allow most minors (aged 12-17) to consent for their own sexual health care without parental permission:31 states explicitly include HIV testing and treatment as part of services accessible to youth. Despite these supportive HIV/STI care access policies for youth, and an ethical context which supports HIV/STI prevention and control with at-risk populations, controversy about parental permission and minors' \"maturity\" remain in research. According to the; see 45 CFR 46.402): \"assent\" is defined as a child's affirmative agreement to participate in research; \"permission\" is defined as the agreement of parent(s) or guardian(s) to the participation of their child or ward in research; and \"informed consent\" occurs when someone who is legally able to consent (> age 18 years) gives permission after having the knowledge of the possible risks, probable consequences, and alternatives. Empirical data support minors' competence to consent to research from the age of 12 and above, with recommendations for a dual child and parent consent only when the child has not reached the age where he/she is allocated rights for independent consent. Before the age of 12, or if the child has not reached the age of independent consent, minors may assent to research along with their parents'/guardians' consent for their participation (; see 45 CFR 46.408).\nValid medical, legal and ethical concerns exist regarding parental permission, waivers of permission, assent or consent by youth, and the definition of \"child\"/\"minor\" (someone under the age of majority, usually less than 18 years) in youth-focused practice and research. These issues are complex and often challenging for investigators, institutional review boards (IRBs), parents, youth, and community advisors. In addition, federal and local laws should be considered and balanced with the goals of protecting youth from risks. Understanding youths' evolving maturity and autonomy and the importance of low-risk, biobehavioral and clinical research activities for youth-focused public health practice warrant consideration.\nAt the intersection of ethics and law, two key areas potentially cause controversy in IRB determinations for sexual health research with youth: 1) level of risk, and 2) whether minors are emancipated for medical decision making under state or local law. Minimal risk studies are those in which the \"probability and magnitude of harm or discomfort anticipated in the research are not greater in and of themselves than those ordinarily encountered in daily life or during the performance of routine physical or psychological examinations or tests\" (; see 45 CFR 46.102(i)). note that in the absence of empirical data on the risks of daily life and routine examinations among children, IRB members may default to intuitive judgement of these risks, which can lead to systematic errors in interpretation and implementation of federal regulations. An IRB's assessment of minimal risk may also vary by institutional setting (e.g., academic center or hospital). In addition to risk determination, federal, state and local laws regulate issues such as the age of medical emancipation which determines whether minors can make medical decisions in the absence of a parent/guardian. From a research perspective, conflict can arise when IRBs disagree on the interpretation of state law in relation to a study's level of risk.\nDuring research collaborations, when multiple IRBs provide study oversight, the views and perspectives of IRB members may differ. These IRB disagreements can be challenging if they potentially lead to research delays, especially if the research is addressing public health prevention priorities, such as sexual health. noted the potential negative implications of local and federal IRB disagreements and suggested lessons learned to facilitate future adolescent sexual health research. Our current experiences (2012-2013) suggest that more still needs to be done to improve timeliness of human subjects' reviews, reduce IRB disagreements, and improve synergies among multiple entities in a youth-focused research team.\nIn this paper, we describe challenges and successes in the pre-research, human subjects' local and federal review processes that were undertaken before beginning a youth-focused, HIV/STI prevention research project with sexually active youth. The case study explains the issues we faced when seeking approval for a minimal risk study involving Black youth of minority age, all of whom were receiving outpatient mental health care services. At center stage was the controversy surrounding whether or not a waiver of parental consent was legally or ethically necessary under the federal rules for human subjects protection. Final approval was received by the federal funding agency, the local health department, and the University after reaching an understanding about the level of risk of the study and the fact that the youth were medically emancipated minors who were competent to consent to research participation under applicable state law. We believe the lessons learned through working with two IRBs and federal-level reviewers, and seeking a non-IRB-affiliated youth-expert legal opinion, may provide important contextual information for others working with youth in HIV/STI prevention research. Additionally, given youth-related consent challenges in both clinical research and practice, this topic may have implications for broader health-related strategies with youth, which are especially important given the urgent context of HIV/STIs among racial/ethnic minority youth.\nPhiladelphia, Pennsylvania is a northeastern city whose large, urban school districts ranked second nationally (after Memphis, Tennessee) among similar school districts on percentage of high school students who ever had sexual intercourse (61.0%, 95% CI: 56.1-65.6%) and who first had sexual intercourse before 13 years of age (15.1%, 95% CI:13.0-17.5%). Data from Philadelphia high school districts also ranked their high school students first among similar school districts regarding the percentage reporting four or more sex partners during their lifetime (27.2%, 95% CI:23.9-30.8%) and sexual activity during the most recent three-month period (44.9%, 95% CI: 40.4-49.6%). At the time of our study (2011), the rate of diagnoses of new HIV infections among youth aged 13-24 in Philadelphia was 56.1 per 100,000 population, over twice the national rate of 26 per 100,000 for persons aged 13-24 (; see Figure 1b).\nGiven the high rates of sexual risk behaviors among youth with mental illnesses and behavioral disorders, our HIV/STI risk-reduction study focused on youth receiving care in outpatient mental health treatment programs who reported current sexual activity. At the time of the study, the most common psychiatric diagnoses among Black youth in mental health treatment in Philadelphia were: attention deficit/hyperactivity disorder (43%), adjustment disorder (36%), oppositional defiant disorder (23%), disruptive behavior disorder (14%), and depression (11%); none of which are barriers to consenting for one's own care if under age 18 and assessed as competent by the mental health care providers. Due to the local epidemiology in Philadelphia, with Black youth being disproportionately affected by HIV/STIs, we sought to enroll youth aged 14-17 years who self-identified as Black (any racial or ethnic designation throughout the African diaspora) to develop and test an HIV/STI prevention intervention for at-risk Black youth receiving mental health treatment in an urban area.\nIn the state of Pennsylvania, minors (youth aged 14 to 17) can legally consent to both mental health treatment and HIV/STI testing and treatment without parental consent (Juvenile Law Center, 2006). This is especially important in the context of biobehavioral research, because under federal regulations, children are \"persons who have not attained the legal age for consent to treatment or procedures involved in the research, under the applicable law of the jurisdiction in which the research will be conducted\" (; see 45 CFR 46.402(a)). This has been interpreted to mean that if a minor is able to consent to medical health services under state law, the minor is also able to consent to participate in medical research. Therefore, the informed consent of minors in Pennsylvania is legally sufficient for participation and no parental permission or waiver is required.\nWe proposed to develop and test a HIV/STI risk-reduction intervention with sexually active Black youth receiving outpatient mental health treatment in Philadelphia. We established a youth-led community advisory board (CAB) and a youth advocate/ombudsman to ensure that the perspectives of the target population were infused through each aspect of the study. The youth CAB also created the study name: \"We are Kings and Queens.\"\nFor the group-level behavioral intervention (Authors), participants were randomized to either the HIV/STI risk-reduction program (treatment; n = 51) or general health promotion program (control; n = 57). The intervention consisted of a two-day, six- hour, skills-based, interactive educational program. The study procedures included focus group discussions (to inform the intervention content), electronic surveys (to collect demographic and behavioral data), diagnostic case ascertainment with the Mini-International Neuropsychiatric Interview, urine specimen collection for Chlamydia and Gonorrhea testing, and an oral swab for OraQuick ADVANCE Rapid HIV-1/2 antibody testing (unless declined by the participant). Laboratory testing was conducted for participants in both intervention conditions.\nThese research procedures were specific to the study and not part of routine care at the treatment programs. Two of the partnering agencies, however, did have relationships with outside providers to offer HIV testing onsite, reflecting moves toward the integration of HIV and behavioral health treatment. The primary outcome was consistent condom use. Secondary outcomes included sexual activity (frequency of vaginal, anal and oral sex), the number of concurrent and sequential sex partners, and laboratory confirmed HIV/STIs. We performed assessments at baseline, immediately post-intervention, and at 3-, 6-, and 12-month follow-ups.\nBefore beginning the study, human subjects approval was required from three groups: 1) the IRB of the academic home institution; 2) the IRB of the local health department; and 3) the reviewers at the federal agency that funded the study. The study materials were submitted to each group and revised several times to clarify wording and address concerns. Changes made to meet the requirements of one agency were resubmitted to the other agencies for their review and approval. Full board review was required given the study's complexity, which meant (at minimum) month-long waiting periods between review meetings. Some of the discussion points included: the appropriateness of mixed-gender focus groups for adolescent sexual health research, confidential recruitment of adolescent participants in clinics when parents/guardians are present, and actions to be taken for positive HIV/STI test results (e.g., linkage to care procedures). Additionally, given our target group of youth with mental illnesses, there was increased attention to human subjects' protections due to concerns regarding competency to provide consent and whether parents/guardians would be notified if their child tested positive for HIV/STIs.\nThrough a series of face-to-face meetings and email exchanges, we worked to address the concerns. We advocated for mixed-gender focus groups to preserve the richness of data that stems from the interactive dialogue between heterosexually-active males and females. We emphasized the high caliber training our facilitators received and created a behavioral management plan, at the IRB's request, to indicate how we would handle potentially challenging group dynamics. For participant recruitment when a parent/guardian was present, we agreed that recruiters would directly address both the parent/guardian and adolescent, identifying himself/herself as a research team member for a study on teen relationships. The adolescent was then informed that he/she could call the number on the business card for additional information. Adolescents were not screened in the presence of parents/guardians, and parents/guardians were not given details about the study. However, if a parent/guardian stated they did not want their child to participate in the study (at the time of approach or any time thereafter) we conceded to the IRBs request that we would not contact or enroll the adolescent in the study, even if he/she independently expressed interest in participation. Given that our target population of youth had all provided consent for their mental health treatment, the IRB approved our determination of competence to provide consent by study personnel as part of the screening process for enrollment. All participants were notified of their HIV/STI results. Those who tested positive for Chlamydia or Gonorrhea (n = 8, 7.4% at baseline) were notified of their results and referred to receive free treatment through the local department, or from their primary care provider. No participants tested positive for HIV, but positive cases would have been followed by the AIDS Service Organization that conducted the testing for confirmatory tests and linkage to care. While we were able to resolve these issues, there was a fundamental disagreement in the interpretation of the state law between the investigators and the review entities. The research team did not believe parental permission was warranted/applicable, while several local IRB members required parental permission, or at minimum, a solid justification for the appropriateness of a waiver.\nBased on Pennsylvania minor consent laws, the participants in this study did not qualify as minors (they did not meet the regulatory definition of minor) for purposes of human subject review; when minors do not meet these qualifications, they can participate in research as adults. Despite the documented legal guidance, obtaining approval became a challenge when the local and federal agencies disagreed about whether parental permission was required for the study. More specifically, the minors' consent to medical health services was not viewed by all parties as sufficient to justify research consent. In the opinion of several IRB members, medical/mental health care was a necessity, while research involvement was a voluntary procedure that they believed would require parental involvement. In other words, at the intersection of ethics and law, some reviewers believed that while the minor was medically emancipated under state law to make decisions, the ethical risk associated with research participation outweighed the state regulations.\nWe had multiple discussions with the committee members to provide context and accurate data regarding the Health Information Portability and Accountability Act (HIPAA) and the protected confidentiality of medical data, the urgency of the HIV epidemic among young people in Philadelphia (see Figure 1b), and the legal ramifications of sharing adolescent test results with parents without youth consent. We also provided information to the local and federal review agencies about the state laws and federal guidance in support of minors' consent for their own mental health and sexual health services. For example, the stated that \"...assent of such mature minors should be considered sufficient with respect to research about conditions for which they have legal authority to consent on their own treatment\" (pg. 18). Thus, although parental permission was not technically applicable under state law and federal guidance (Juvenile Law Center, 2006), our ethical review process required that we address the issue of parental permission/involvement.\nWe advocated to consent participants in the absence of parental involvement for several reasons: 1) to protect the youth participants' privacy regarding their involvement in consensual sex; 2) to ensure youth receive HIV/STI testing and treatment (if needed); 3) to encourage participants to give honest answers to the study questions (without fear of parent/guardian reactions); and 4) to be in line with state and federal guidance on the issue. Previous research with youth suggests that requiring parental permission may decrease their interest in participating in biobehavioral research, especially when STI testing is involved. In addition, some parents/guardians may request to receive their child's test results, which would be counter to the youth's desires and legal precedent for maintaining their confidentiality. Requiring parental permission would also violate local and federal rights and breach confidentiality for youth whose parents/guardians did not know that they were receiving mental health treatment, engaging in consensual sexual activity and possibly seeking sexual health services.\nDespite eleven separate meetings and discussions, the local and federal approving agencies were unable to reach initial consensus about parental involvement. The federal funding agency waited to consider the decisions of the two local IRBs before completing its review. The local IRBs suggested obtaining a youth-focused third party review of the protocol to help support a decision. We contacted attorneys at the Juvenile Law Center, a non-IRB-affiliated youth-legal expert firm in Philadelphia. They reviewed the study materials and concluded that the study's consent provisions were consistent with the Mental Health Procedures Act and HIPAA:a minor in Pennsylvania age 14-17 did not need parental consent to participate in the study. After several review and feedback sessions, both the academic institution and local health department IRBs approved written informed consent by the adolescent participants and waivers of parental permission for their parents. Approval by the local IRBs facilitated the green light by the federal agency to begin the study. The study was approved by all required local and federal bodies in March 2013; overall, a 14-month timeline for full review and approval of this protocol with associated suboptimal use of human and fiscal resources due to the lengthy delay.", "gender": "Female" } ]

He was maintaining oxygen saturation of 88% on 6 L nasal cannula. Initial blood work was remarkable for leukocytosis 25.86 (ref: 3.1-8.50 x 103/uL) with bands elevated at 9%, anion gap 15, lactic acid elevated 3.3 (ref: 0.5-2.0 mmol/L), mild transaminitis with aspartate aminotransferase (AST) 113, and alanine aminotransferase (ALT) 153. Physical examination was remarkable for decreased air entry with bilateral crepitation. Computed tomography pulmonary embolus study confirmed presence of bilateral acute pulmonary emboli with possible right heart strain and bilateral infiltrates consistent with COVID-19 pneumonia. He was treated with heparin infusion, remdesivir, dexamethasone, 1 dose of vancomycin, and piperacillin-tazobactam as well as supportive breathing treatments consisting of albuterol nebulization as needed. He was then admitted to the medical floors for further management.\nEchocardiogram obtained later was resulted as normal left ventricular function with ejection fraction 55% to 65% with normal right ventricular pressure and no evidence of right ventricular dysfunction. Heparin infusion, remdesivir, and dexamethasone were continued. Vancomycin and piperacillin-tazobactam were given the initial 2 days to cover for superimposed bacterial pneumonia and later deescalated to amoxicillin-clavulanic acid on days 3 and 4 of hospitalization. Ultrasound abdomen done on day 4 showed no abnormalities within the liver or gallbladder.\nDuring hospitalization, patient was noticed to have worsening of liver enzymes which peaked at ALT 721 IU/L (normal <55 U/L) and AST 305 IU/L (normal value < 35 U/L). Other laboratory values were gamma-glutamyl transferase 114 IU/L (ref: 12-64 IU/L), albumin 2.7 g/dL (ref: 3.4-4.8 g/dL), alkaline phosphatase 49 IU/L (ref: 56-119 IU/L), and international normalized ratio 1.5. Further workup showed pro-calcitonin minimally elevated at 0.28 (ref: <0.05 ng/mL), d-dimer elevated at 12.89 (ref: <0.5 mg/dL), and fibrinogen was normal. His blood alcohol and acute hepatitis panel were negative on day 2 of hospital admission. Acetaminophen levels obtained on hospital day 4 were <0.6 (ref 0.00-50.0 microg/mL). At that point, remdesivir was discontinued on day 2 of admission as it was thought to have contributed to worsening of liver function. Antibiotics were discontinued as bacterial infection was less likely and it was thought amoxicillin-clavulanic acid could also have contributed to liver enzyme abnormalities. Computed tomography abdomen and pelvis with contrast (day 8) showed mild splenomegaly with no abnormalities noted in the liver or gall bladder.\nDespite discontinuation of remdesivir, antibiotics, and improving oxygen requirements, his liver function continued to worsen (see Table 1) and additional workup including autoimmune work up with anti-smooth muscle antibodies, systemic lupus erythematosus, and vasculitis panel were done and reported negative. Further testing with EBV and cytomegalovirus (CMV) serology were done, which revealed EBV viral capsid antigen (VCA) IgM positivity.

He also had no family history of diabetes, autoimmune diseases, and hereditary diseases. Psychosocial assessment showed that the patient had no mental, physical, or emotional health issues. After unsuccessful treatment with trans-hepatic arterial chemotherapy and embolization (TACE), the patient voluntarily participated in the CISLD-1 trial, provided signed informed consent in July 2019, and started to receive Sintilimab at a dose of 200 mg every 3 weeks.

Chest computed tomography (CT) revealed bilateral multifocal subpleural and peribronchial ground-glass opacities typical of COVID-19 pneumonia (Figure 1B and Supplementary Figure 2). The clinical condition gradually deteriorated with sub-febrile episodes, persisting dry cough and diarrhea, and progressive weight loss and cognitive dysfunction (Figures 1C, D and Supplementary Information). Inflammatory parameters and blood cell counts remained abnormal (Figures 1A, E), while persisting SARS-CoV-2 infection was confirmed (Supplementary Figure 1B). Complementary investigations excluded other diagnoses (Supplementary Information). No specific antiviral agents were introduced given the mild symptoms of COVID-19 (e.g. absence of hypoxemia).\nIn summary, the patient developed a long-lasting SARS-CoV-2 infection likely related to his severe immunosuppressive status. Consequently, we hypothesized that convalescent plasma could be beneficial in this particular case, by providing virus-specific neutralizing antibodies as well as a potential anti-inflammatory effect. Plasma units (3x200 ml/donor) were obtained from three selected donors, who had fully recovered from mild COVID-19 disease (Supplementary Information). Each donor presented relatively high IgG antibody titers against the S1 (spike)-protein using Euroimmun ELISA (Supplementary Figure 3A). The first cycle of ABO-compatible plasma transfusion (two units on two consecutive days) was given on days 72 and 73 after diagnosis of SARS-CoV-2 infection, followed by three additional cycles, administered 10 to 15 days apart (Supplementary Figure 3A).", "gender": "Male" } ]

Her family history was remarkable for early-onset CAD and high cholesterol levels. She had received weekly or biweekly LDL-apheresis therapy since 10 years of age. As her LDL-cholesterol levels were far from the treatment goals, oral lomitapide 5 mg/dl was introduced on top of atorvastatin (80 mg/day) and ezetimibe (10 mg/day) at 20 years of age. The dose was titrated up to 20 mg/dl and has been maintained without adverse events. An additional 31% LDL-cholesterol reduction was observed in the first month of low-dose lomitapide (5 mg/day) therapy. At a dose of 20 mg/day, the LDL-cholesterol reduction reached 49% at the end of 6 months. As she declined to be weaned off apheresis, we reduced the apheresis frequency and she received low-dose lomitapide (20 mg/day) plus concomitant bimonthly apheresis. However, during the pandemic for 1 year, she could not access apheresis. Throughout the 8-year lomitapide treatment, she did not experience any increase in serum liver enzyme levels, weight loss, or liver steatosis. Moreover, no change was observed in hepatic fibro scans. She followed a fat-restricted diet compatible with lomitapide therapy to prevent steatorrhea, with concomitant supplementation of fat-soluble vitamins and essential fatty acids. Since the commencement of lomitapide therapy, the patient has remained stable at functional class (NYHA-I) without any adverse cardiovascular events.\nImaging work-up at diagnosis revealed mild aortic stenosis [aortic peak gradient (AoPG) of 30 mmHg-mean (AoMG) 23-18 mmHg] and mild aortic regurgitation with a normal ejection fraction (EF).

He has presented with exertional angina and angiographically extensive ostial coronary stenotic lesions and had undergone CABG accompanied by aortic root dilation at 20 years of age. One year later, he was referred to our lipid clinic for extremely high LDL-cholesterol levels ranging between 420 and 540 mg/dl. Xanthomas were apparent on his elbows, knees, and ankles. He was already prescribed rosuvastatin (40 mg/day) and ezetimibe treatment, and we introduced LDL-apheresis. He lived a 14-h drive from our center; therefore, he receive monthly apheresis. As his LDL-cholesterol levels were still >200 mg/dl post-apheresis, we introduced lomitapide in June 2014, when he was 25 years of age. At the initial dose of oral 5 mg/day, mild nausea was observed. With the up-titrated dose of 20 mg/day, his nausea did not increase; however, after 6 months, he declined to take his pills as he experienced an 8 kg weight loss. For the next 3 years, he continued monthly apheresis but no lomitapide. We re-introduced lomitapide in November 2017 due to persistent LDL-cholesterol levels >500 mg/dl. However, this time he was compliant with the low-fat diet and lomitapide. He did not experience any adverse symptoms or weight loss with an up-titrated dose to 40 mg/day.

On examination, there was pansystolic murmur in the precordium. Her electrocardiogram was normal, and chest X-ray showed no cardiomegaly. Transthoracic echocardiography (TTE) revealed bileaflet prolapse with non-coaptation and posteriorly directed eccentric jet. Left atrium was dilated. Both the ventricles were normal in size and function. She was posted for mitral valve replacement. Intraoperative transesophageal echocardiogram (TEE) confirmed preoperative findings. There was a band like structure seen in the midcavity of left ventricle connecting the two walls (Figure: 1, Video: 1). Mitral valve replacement with 27ATS valve and false tendon (FT) excision was done under cardiopulmonary bypass with moderate hypothermic cardioplegic arrest. However, postoperative TTE showed that the midcavity FT was still intact (Figure: 3). Retrospective interpretation of intra operative TEE images showed the presence of two false tendons. Along with first FT in LV mid-cavity (Figure: 1, Video: 1), a second FT was faintly seen below the mitral valve (Figure: 2, Video: 2) coursing towards the left ventricular outlet. Only the second FT was excised by the surgeon. The patient recovered from the surgery uneventfully.\nFalse tendons are benign anatomic variants present in 40% of people. When LVFTs are oriented perpendicular to the flow of blood, they vibrate like the strings of an Aeolian harp. These vibrations are seen as fine fibrillations on M-mode images [Figure 3]. Patients with LVFTs are said to have violin heart as they frequently have musical systolic murmurs on precordial examination. Echocardiographically LVFTs can be differentiated from LV thrombus, LV hypertrophy, hypertrophic cardiomyopathy and trabeculations by the presence of echo-free space on both sides of the tendons. LVFTs have systolic laxity and become taut during diastole. LVFT may be cut by the surgeon as in our case or may rupture spontaneously or after an myocardial infarction, after percutaneous trans luminal mitral commissurotomy. Ruptured LVFT must be differentiated from ruptured chordae, vegetations or thrombi.\nThe presence of LVFT carries both merits and demerits. Its presence can prevent left ventricular (LV) remodeling. However it may be a causative factor in the development of discrete subaortic stenosis (DSS)\nLeft ventricular false tendons were first described by Sir Turner, a British anatomist and surgeon who proposed that they retard LV enlargement. In dilated cardiomyopathy or after myocardial infarction, LV dilates due to remodelling. Dilated ventricle increases wall stress and leads to LV failure. Increased wall stress also increases metalloproteinase activity that degrades myocardial extracellular matrix causing further LV dilatation. Transverse midcavity LVFTs absorb the distorting forces resulting in less remodelling, less mitral annular dilatation and LVEDD. In patients with dilated cardiomyopathy, Coapsys device (Myocor, inc) is utilized to reduce the LV wall stress. It is a flexible cord that is attached to the LV walls by epicardial pads and contains a cord that traverses the LV cavity anteroposteriorly. It is considered as a prosthetic false tendon. LVFT produces atrial natriuretic peptide(ANP) similar to left atrium when LV filling pressure are increased which promotes natriuresis, diuresis and vasodilatation resulting in reduced LV wall stress. ANP also retards LV remodelling by inhibiting endothelins, angiotensin-II and aldosterone, all of which promote cardiac fibrosis and remodelling. LVFT also produces ANP.\nDilated and ischemic cardiomyopathy cause functional mitral regurgitation (FMR) by LV remodelling. The papillary muscles are displaced away from the mitral annulus as measured by tenting height and area. Incomplete mitral coaptation occurs due to the traction on the chordae tendinae. Coaptation device or surgical struts help to preserve the subvalvular anatomy and reduce the degree of FMR. In a study conducted by Bhatt et al., transversely oriented LVFTs were found to produce less FMR by having less coaptation depth and area.\nLeft ventricular false tendons may contain Purkinje fibres, which have a gating mechanism that may inhibit or promote re-entry from ventricular tachycardia. In patients with dilated ventricles, conduction of the electrical impulse through LVFTs may produce a more homogenous LV depolarization similar to biventricular pacing and improve LV dP/dt.\nThe presence of LVFTs in patients with DSS may add to the flow turbulence across the LVOT. Some surgeons excise LVFTs during DSS excision.\nIn our patient, there were two false tendons, one was traversing LVOT and it was excised by the surgeon. The transverse midcavity tendon was left intact, which may protect the patient from future possibility of FMR. People with LVFTs may be at evolutionary advantage due to reduced LV remodelling after MI and reduced the degree of FMR.", "gender": "Female" } ]

On exploratory laparoscopy we found a large perforation (about 5 cm of size) in the first duodenum portion (Fig. 2). We converted the procedure to open surgery in consideration of the extension and position of the lesion that did not allow us to continue safely in laparoscopy. We achieved a distal gastrectomy with Roux-en-Y side-to-side gastro-jejunostomy. The patients were satisfied with the treatment received, the postoperative course was uneventful and the patient was discharged on POD 7. The intraoperative findings appeared to be not unequivocal, configuring on the one hand the hypothesis of perforation on a large peptic ulcer or on a chronic pancreatitic process but we could not exclude the presence of a neoplasm by a gastro-duodenal origin. The histopathological examination described, 2 cm from the distal pyloric margin and in the context of the pyloric type mucosa, a centimetric neoformation with histological and immunophenotypic characteristics of well-differentiated neuroendocrine tumor (NET G.1 s. WHO 2019 classification, Synaptofisina + and Chromogranina +). In the adjacent mucosa we saw multiple erosion/ulceration phenomena, with bleeding spillage and vascular congestion. The gastric wall was all affected by outbreaks of chronic inflammation, sometimes in follicular aggregation and with fibrosis also extended to the subserosa. These aspects, in relation to the presence of a NET G1 and multiple erosive/ulcerative areas near the pyloric margin, were suggestive of a clinical picture of Zollinger Ellison syndrome.", "gender": "Male" } ]

He could not manage his work as a teacher, for example, creating tests and making decisions at school. Impairments appeared in his daily life activities, such as mistakes in transferring money through telebanking. He presented abnormal behavioral symptoms with an obsessive personality, for example, being stingy with money and also did not allow anyone to spend his money without prior discussions and permission. Patient did not have any medical disease prior to his cognitive decline, and family history was unremarkable since neither his parents nor his siblings showed any cognitive impairment or dementia so far. However, his 14-year-old daughter was mentally handicapped (Figure 1).\nNeurologic examination did not reveal any focal or lateralizing neurologic deficit. Routine laboratory tests, including blood chemistry, electrolyte, and urine analyses, were normal. Serum Venereal Disease Research Laboratory (VDRL) results, including those for Treponema pallidum particle agglutination assay (TPHA), were negative. Thyroid function tests were normal, as with vitamin B12 and folic acid levels. The patient's apolipoprotein E (APOE) genotype was epsilon3/epsilon3. This patient was diagnosed according to the diagnostic criteria for \"probable AD\" by the National Institute of Neurological and Communicative Diseases and Stroke/Alzheimer's Disease and Related Disorder Association, which were ascertained by clinical features, neuropsycho-logical test, and brain magnetic resonance imaging (MRI) imaging with single-photon emission computed tomography (SPECT). Brain MRI revealed mild cortical atrophy without any ischemic change or other lesions (Figure 2A). Brain SPECT showed moderate hypoperfusion in the frontal, limbic, and temporal areas (Figure 2B). The reduced cerebral blood flow from the images of brain SPECT also supported the AD diagnosis.\nThe patient underwent comprehensive neuropsychological tests, and he scored 23 out of 30 (2 percentile) on the mini-mental state examination. The subscores for time orientation and seven-serial calculations were 4 out of 5 and 1 out of 5, respectively. The delayed word recall score was 1 out of 3, and he scored 1 out of 3 in the task of clock drawing (Figure 3). His score fell in the abnormal range on the attention task of backward digit span (2.5 percentile). Significant impairment appeared in his confrontation naming ability (<0.01 percentile). Performances in copying the intersecting pentagon test and Rey-Osterrieth Complex Figure test were normal, but his performances on clock drawing were severely impaired (5 percentile). On the Seoul verbal learning test, he was able to recall 13 items (0.02 percentile) in three consecutive immediate recall trials, but only 3 items (0.3 percentile) in the 20-minute delayed recall. Poor visual memory score of 10 out of 36 (1 percentile) was obtained in the delayed recall of the Rey-Osterrieth Complex Figure test. He showed abnormal performances in several tasks of frontal and executive functions, especially in the controlled oral word association test, Stroop test, and trail making test.\nPatient was diagnosed as probable EOAD, based on clinical assessment, detailed neuropsychological tests, and neuroimaging studies including brain MRI and SPECT.\nGenetic tests were performed in the patient to evaluate possible mutations. We were unable to make segregation analysis, since all family members and relatives refused the genetic test. The patient declined the genetic test for his children too. None of his family members presented any cognitive decline or dementia phenotypes, but they did not agree in releasing other family information. This patient was included in the Clinical Research Center for Dementia of South Korea study, which screened potential causative mutations in 100 patients with EOAD. Details of the clinical and scientific analyses of EOAD mutations in the Clinical Research Center for Dementia of South Korea study have not been included previously. A detailed clinical investigation of this patient with detailed personal interview, MRI, SPECT imaging data, and bioinformatic analyses are presented.\nVenous blood samples (5 mL) were collected from the patient with an ethylenediaminetetraacetic acid blood drawing tube. Blood sample was centrifuged at 1,500 x g for 5 min, followed by separation of white blood cells (buffy coat) for its storage at -80 C. DNA was purified using GeneAll Blood Protocol kit (GeneAll Biotechnology, Seoul, Korea), and purified DNA was kept at -20 C until the analysis.\nA polymerase chain reaction (PCR)-based analysis was performed using primers, as previously described. Targeted potential EOAD genes were as following: APP exons 16 and 17, PSEN1, and PSEN2. Since the diagnosis of EOAD is complicated due to the pathologic overlaps within diverse neurodegenerative disorders, this patient was also screened for progranulin (PGRN), microtubule-associated protein tau (MAPT), and prion (PRNP) genes.\nThe PCR products were purified using GeneAll Expin PCR kit (GeneAll Biotechnology). Single-strand conformation polymorphism was performed. Samples were mixed with formamide and incubated for 10 minutes at 95 C to generate single-stranded DNA bands. For separation, native polyacrylamide electrophoresis (BioRad, Seoul, Korea) was performed for 21 hours. SYBR Gold (Thermo Fisher Scientific, Waltham, MA, USA) staining was used to visualize the DNA bands.\nTo confirm the mutation, all PCR products were sequenced with the same primer sets in both directions by BioNeer Inc. (Dajeon, Korea). Before sequencing, we purified the PCR products by using GeneAll PCR kit (GeneAll Biotechnology). Big Dye Terminator Cyclic sequencing was performed with the ABI 3730XL DNA Analyzer (http://eng.bioneer.com/home.aspx; BioNeer Inc.). Sequencing data were screened with DNA BASER (http://www.dnabaser.com) software. Sequence variants were identified by NCBI (http://www.ncbi.nlm.nih.gov/gene) and UniProt (http://www.uniprot.org) databases.\nMutations were analyzed by PolyPhen-2 (http://genetics.bwh.harvard.edu/pph2/) online in silico prediction program, which predicted the pathogenic nature of missense mutations. PolyPhen-2 used homology search, multiple sequence alignment, profiling, identity-based scores, and structure-based search parameters (such as accessible surface area and hydrophobicity features). These predictions could define the putative role of missense variants and could predict whether they were probably/possibly damaging or benign. PolyPhen-2 also provided the multiple sequence alignment, which compared the homologous sequences from different organisms. Two types of datasets were used for the prediction: HumDiv and HumVar scores. HumDiv was used for testing the pathogenicty of rare alleles, where mildly damaging variants must be treated as possibly damaging. HumVar was used in case of Mendelian disorders, where more damaging alleles should be distinguished from the less damaging ones.\nWe also analyzed the mutation with SIFT algorithm (http://sift.jcvi.org/), which used several databases such as SWISS-PROT, SWISS-PROT/TrEMBL, and NCBI Protein Database. The software analyzed the possibility on the pathogenic properties of mutations by comparing the mutant and normal variants. SIFT scores of point mutation were calculated for weighting the mutations as possibly damaging allele or tolerated (nondamaging), with a dividing score of 0.05, respectively.\nProtein structure prediction analysis of PSEN2 was performed by Raptor X program at the University of Chicago (http://raptorx.uchicago.edu). Normal PSEN2 was composed of 488 amino acids, starting at 61 residues and continuing till residue 448. The prediction was performed at Raptor X web server for both normal PSEN2 and R62C mutation. Based on PSEN2 information from the UniProt database, R62C mutation belonged to the topological domain, positions 1-87, including the mutation site.

The pain was insidious in onset, non radiating and had no diurnal variations and was aggravated on shoulder movements and relieved on taking medications. The local temperature was elevated and superficial veins were engorged. There was no regional lymphadenopathy and no neurovascular deficit in left upper limb.

His chest X-ray showed patchy consolidation over the right lower lung zone (shown in Fig. 1). The initial brain MRI showed prominent leptomeningeal enhancement at bilateral brainstem, cerebellum, and right cerebral sulci (shown in Fig. 2a, b) and a non-enhanced oval shape lesion at the SCC with increased signals in diffusion-weighted imaging (DWI), low signals in apparent diffusion coefficient (ADC), and hyperintensity in T2-weighted fluid-attenuated inversion recovery (T2-FLAIR) (shown in Fig. 3a-d). The cerebrospinal fluid (CSF) analysis revealed turbid appearance, significantly high pressure (420 mmH2O), lymphocyte-predominant pleocytosis (white blood cells 148/muL, lymphocytes 95/muL), reduced glucose (43 mg/dL), and elevated protein (519 mg/dL). The biochemistry assay was all normal, including sodium, which was 136 mmol/L. The CSF pathogen studies were negative in bacteria, syphilis, fungus, tuberculosis, and virus via multiple polymerase chain reaction (FilmArray Meningitis/Encephalitis). The viral serology surveys including varicella zoster virus, herpes simplex virus, cytomegalovirus, and Japanese encephalitis virus were also negative. Serology detection for M. pneumoniae using rapid immunochromatographic test (Biocard M. penunoniae IgM kit, Labsystems Diagnostics, Finland) showed IgM positive at a titer of 1:320 (normal value <1:40) on the 2nd admission day, indicating an acute M. pneumoniae infection. Neither polymerase chain reaction analysis nor antibody detection of M. pneumoniae in the CSF was available in our hospital.

A twelve-lead electrocardiogram showed normal sinus rhythm with non-specific ST-T changes; echocardiography performed two days previously revealed normal-sized ventricles, mild anterior hypokinesis, with normal wall motion, and a left ventricular ejection fraction of 55%.\nA proposed plan of general endotracheal anesthesia, with invasive hemodynamic monitoring, was discussed with the patient; cell saver services, and four units of packed red cells, were made available for the surgery. After premedication with intravenous midazolam (2 mg), the patient was transferred to the operating suite; routine monitors revealed a baseline BP of 122 / 97 and normal sinus rhythm in the mid 60s. Following preoxygenation and induction with fentanyl (3 mcg / kg) and etomidate (0.2 mg / kg), endotracheal intubation was facilitated with cisatracurium (0.2 mg / kg); general anesthesia was maintained with oxygen : air (50 : 50), fentanyl, and isoflurane (0.4 - 0.8%).\nAfter left radial artery catheter placement, a 7-Fr percutaneous sheath was introduced via the right internal jugular vein. Using waveform analysis, a balloon-tipped, flow-directed PA catheter was then slowly advanced through the sheath. Right atrial tracing, followed by right ventricular waveform, were duly noted until the catheter tip reached 55 cm, when the EKG monitor suddenly demonstrated asystole; systolic BP decreased precipitously from 110 to < 50 mmHg, and the arterial waveform disappeared. The PA catheter was immediately deflated and withdrawn completely, without any improvement. Cardiopulmonary resuscitation was initiated with chest compressions and intravenous administration of epinephrine (1 mg) and atropine (1 mg). The patient responded to this management in two to three minutes, with a quick return to sinus tachycardia, with occasional premature ventricular contractions (PVCs) and ST-segment depression. An intraoperative cardiac consultation was obtained; the cardiologist recommended urgent cardiac catheterization and rescheduling of the surgical procedure.\nThe patient was transferred to the Intensive Care Unit, where he continued to do well, and was extubated later that evening.

An 80-year-old gentleman was referred to our eye unit for assessment of bilateral cataract. His past medical history included type 2 diabetes and seropositive rheumatoid arthritis controlled by sulfasalazine. The corrected distance visual acuity (CDVA) was 20/25 in the right eye (OD) and 20/50 in the left eye (OS). Slit-lamp examination showed bilateral grade 3 nuclear sclerotic cataract (based on the Lens Opacities Classification System III) with no other ocular abnormality detected. He underwent an uneventful phacoemulsification with intraocular lens implant and was started on topical prednisolone 1% TID, ketorolac 0.5% TID and chloramphenicol 0.5% TID postoperatively. Topical ketorolac was started postoperatively to reduce the risk of macular oedema after cataract surgery in view of the history of diabetes.\nAfter 1 week, the patient presented to the eye emergency department with an acute left eye pain and hand movement vision. Slit-lamp examination showed a left inferior, noninfiltrated, crescentic corneal melt with epithelial defect, spanning 4-8 o'clock position (away from the temporal primary corneal incision), with a small Seidel-positive corneal perforation and flat anterior chamber. There was severe corneal punctate staining in the left eye and mild punctate staining in the right eye, suggestive of underlying DED. A left emergency corneal suturing and reformation of anterior chamber was performed. All postoperative drops, such as topical preservative-free sodium hyaluronate 0.2% Q2H, levofloxacin 0.5% Q2H and dexamethasone 0.1% BD, were discontinued. Oral prednisolone 40 mg was started in view of the possibility of peripheral ulcerative keratitis associated with the underlying seropositive rheumatoid arthritis. On the next day, there was a mild persistent leak at the perforated site, which warranted a corneal gluing using cyanoacrylate glue (Histoacryl; B. Braun Medical Ltd, Sheffield, UK) and insertion of a bandage contact lens (BCL). Bilateral lower lid punctal plugs were inserted. Blood tests, including the inflammatory markers, were all normal. The oral prednisolone was stopped after 2 days as there was no convincing evidence of vasculitis or peripheral ulcerative keratitis and the corneal melt was likely attributed to DED. No flare-up of rheumatoid arthritis was reported.\nAfter 1 week, the anterior chamber had successfully reformed. However, the corneal glue and BCL spontaneously dislodged after 2 weeks, resulting in a recurrent pinpoint corneal wound leak with iris plugging. He underwent a repeat corneal gluing and the eye stabilized within a week with a formed anterior chamber. CDVA was 20/50. The cornea successfully re-epithelialized under the glue 2 months later (Figure 1), and the BCL and glue were subsequently removed.

Furthermore, the patient was initiated on intravenous sodium valproate 400 mg two times daily and oral levetiracetam 500 mg two times daily. The drugs were then changed to oral sodium valproate 500 mg two times daily and oral levetiracetam 750 mg two times daily. Improvement was noted with no convulsions and normal cognitive function. Two months later, the serum TPPA was still positive. In addition, the serum RPR was still positive with a titer of 1:8, while the serum LGI1 antibody was positive with a titer of 1:10. Furthermore, a revaluation of the CSF showed that the CSF TPPA and RPR were positive. However, the other CSF tests remained negative. In addition, a repeat of the EEG showed no epileptiform wave emission (Figure 3). Moreover, a repeat of the brain MRI showed no abnormality (Figure 2D). A second course of intravenous penicillin G sodium 3.2 million units every 4 h for 14 days was started. After another four months, the serum TPPA was still positive, the serum RPR test was positive with a titer of 1:8, while the serum LGI1 antibody was negative. Changes in TPPA, RPR, and LGI1 antibodies during the syphilitic treatment are shown in Figure 4. A repeat of the EEG and brain MRI showed normal findings. The third course of intravenous penicillin G sodium 3.2 million units every four hours, was given for 14 days. In addition, oral doses of sodium valproate 500 mg two times daily and levetiracetam 750 mg two times daily were continued. The patient was then followed up for additional three months. The patient reported no further convulsive episodes. In addition, the memory and calculation ability were noted to be normal.", "gender": "Female" } ]

An ultrasound (USS) scan was performed at 11 weeks gestation to exclude an ectopic pregnancy, which demonstrated a singleton viable intrauterine pregnancy with 2 small cervical fibroids (<4 cm) and a small amount of free fluid in the pouch of Douglas (Figure 1). A diagnosis of fibroid red cell degeneration was determined as an explanation for the abdominal pain. A routine anomaly USS was performed at 20 weeks which was unremarkable (Figure 2).\nDue to ongoing episodes of abdominal pain, an abdominal USS was performed at 21 + 4 weeks gestation which demonstrated normal abdominal and pelvic organs and an intrauterine gestation with anhydramnios. On referral to the obstetric team, a bedside USS performed was unable to identify the fetus.\nA subsequent USS was performed in the fetal medicine unit, which proved challenging due to severe oligohydramnios and uterine fibroids. The fetus could be identified and was noted to be lying laterally in the pelvis.\nInitial management for preterm rupture of membranes was implemented; however, an USS 2 days later demonstrated an empty uterus with the fetus situated near the liver.\nThe patient was referred for an urgent MRI which confirmed the diagnosis of suspected abdominal pregnancy (Figure 3).\nThe patient was transferred to a tertiary center for specialist multidisciplinary management at 22 + 1 weeks gestation, with access to interventional radiology services. She was extensively counselled regarding her options for conservative management or surgical termination of the pregnancy. This included discussions with the neonatal team regarding fetal outcomes at extreme prematurity as well as obstetric and anesthetic input regarding maternal risk of major hemorrhage. The patient remained committed to the pregnancy and was admitted for observation.\nAt 24 + 4 weeks gestation, the patient collapsed with clinical signs of acute intraabdominal bleeding. A laparotomy performed revealed 2 liters of hemoperitoneum. The placenta was embedded at the left cornua, continuous with the left fallopian tube and ovary, and adherent to the omentum.\nThe baby was identified extrauterine and delivered alive but in poor condition. Placental tissue continued within the myometrium; therefore, the left cornua were excised and the uterus repaired, with a blood loss of 4000 ml. Postnatally, the woman was managed in ICU and discharged on day 12. Sadly, the baby died at 24 hours of age.", "gender": "Female" } ]

The patient had a cough occasionally and joint soreness but denied any other symptoms. On initial clinical evaluation, the patient's body temperature was 38.4 C, and other signs were within normal limits. Pulmonary, abdominal, cardiac, and neurologic examinations showed unremarkable findings. Laboratory tests revealed that the patient had leukocytosis (20.72 x 109/ml) with 87.4% neutrophils. His C-reactive protein level was high (90.61 mg/L), and a procalcitonin level was slightly increased (0.173 ng/ml). Contrast-enhanced chest CT revealed a large mediastinal mass measuring approximately 7.76 x 4.55 cm (Figure 1A). The rest of the examination was regular.\nAt initial admission, the patient was treated with empiric antibiotic therapy, including piperacillin and sulbactam. However, he still had a recurrent fever, and there was no significant improvement in inflammatory indicators and blood routine examination. To determine the etiology, the patient underwent Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) on the fifth day of admission. The Virtual bronchoscopic navigation (VBN) system is a method to guide the bronchoscope to the lesion by making a bronchial path on a virtual image. The digitized information from the patient's CT scan was imported into the Archimedes VBN system, in which multislice views of the chest and virtual bronchoscopy images were reconstructed. The VBN system shows the bronchial tree, the anatomical structure of the mediastinal mass and visualizes the best path to reach the mediastinal mass (Figures 2A-E). With the guidance of the VBN system, the bronchoscope was navigated to the target bronchus and advanced to the lesion, and then EBUS-TBNA was performed to obtain purulent exudate (Figures 3A-D). Biopsy showed more purulent secretions and a few lymphocytes and macrophages (Figure 4A). Microscopic analysis revealed numerous weakly acid-fast and branching filamentous rod bacteria were identified from the samples on the aspirate smear, and a presumptive microbiological diagnosis (Nocardia) was made (Figure 4B). Metagenomic next-generation sequencing (mNGS) subsequently identified the pathogens as Nocardia species (Nocardia arizonensis and Nocardia cyriacigeorgica). And after seven days of culture, the cultures of purulent exudates ultimately grew the Nocardia species (Figure 4C).\nAfter microscopic examination and mNGS confirmed Nocardia, intravenous imipenem/amikacin was given. The clinical symptoms of the patient were significantly improved after 6 days of treatment. Then he was switched to intravenous imipenem with oral trimethoprim/sulfamethoxazole (TMP/SMX, 80 mg of TMP, and 400 mg of SMZ/tablet) 3 tablets q6h. One month after treatment, the patient improved, and their Chest CT showed a decrease in the size of the mediastinal mass (Figure 1B). He was discharged and continued to be treated with oral TMP/SMX 3 tablets q8h and sodium bicarbonate for 3 months. Over the next 3 months, he continued on oral TMP/SMX 2 tablets q8h and sodium bicarbonate. After six months of treatment, the patient was asymptomatic. His CT showed significant improvement in the mediastinal mass size (Figure 1C). At one and a half years of follow-up, the patient recovered well, and no complications were noted (Figure 1D).", "gender": "Male" } ]

The cancer recurred in 2015 and the patient underwent right total maxillectomy including resection of the right orbital floor with reconstruction, and right neck dissection. She was staged as pT3N0 with positive margins and perineural invasion. PD-L1 tested in the primary tumor by IHC (using Dako 22C3 pharmaDx antibodies) was 70% by tumor proportion score. Tumor DNA analysis by the FoundationOne platform (Foundation Medicine, Cambridge, MA, USA) measured a tumor mutation burden (TMB) of 9, two TP53 mutations and a BRCA1 mutation, among others (Figure 1(c)). Genetic evaluation was negative for any inherited genetic abnormalities.\nFollowing surgery, she underwent adjuvant radiochemotherapy with 66 Gray and weekly cisplatin. Follow-up imaging demonstrated progression of metastatic cancer with lesions in the mediastinum, lung, and liver. The patient started palliative chemotherapy with weekly carboplatin and paclitaxel but progressed after 6 months with increased number and size of the metastases including a 3.5 cm mediastinal mass, a 3.8 cm left lower lobe (LLL) mass, and multiple liver masses measuring up to 5 cm (Figure 1A). Given her recurrent and metastatic status with progression on a platinum-based regimen, she was recommended palliative treatment with single-agent pembrolizumab (given at a dosage of 200 mg/m2 every 3 weeks) and began treatment in October 2016.\nAfter the third administration of pembrolizumab, the patient presented to an outside hospital with a vesicular skin rash associated with severe neuropathic pain and pruritis of the left lower extremity from the thigh down to the shin in a L4-L5 dermatomal distribution. The patient was not vaccinated against herpes zoster virus (HZV). Given the typical clinical presentation (unilateral vesicular skin rash in a restricted dermatomal pattern associated with severe neuritis), the patient was diagnosed with herpes zoster infection and was prescribed valacyclovir. After 7 days of treatment, the skin lesions and pain continued leading to extension of valacyclovir treatment. Given the acute viral infection, pembrolizumab was held. The vesicles gradually improved, but the patient had persistent pain and ultimately developed new open wounds. She was admitted in the hospital where Infectious Disease and Dermatology services were consulted. A biopsy was performed, which was consistent with pyoderma gangrenosum. This was considered to be an isomorphic reaction related to the previous zoster infection. The patient was started on treatment with prednisone. She gradually recovered and prednisone was tapered over 2 months.\nFollow-up computed tomography (CT) scans performed 1 month after the diagnosis of herpes zoster infection (going along with discontinuation of pembrolizumab application) showed improvement in all targeted metastatic lesions. At this time, the mediastinal mass measured 2.7 cm, the LLL mass was replaced with an area of consolidation, and the liver lesions sizes decreased with the largest now measuring 1.7 cm (Figure 1(a)). After another 4 months, the skin lesions healed, and plans were made to resume immunotherapy due to concerns for tumor progression during the long treatment break. Repeated imaging, however, demonstrated stable tumor disease, and as the patient was recovering with limited performance status, resumption of ICI treatment was paused in favor of close imaging monitoring.\nFollow-up CT scans were obtained after another 3 months and demonstrated further decreased sizes of the lung and liver lesions and no measurable disease in the mediastinum or LLL. At this time, the largest liver lesion measured 1.1 cm. On this basis, the decision was made to continue active surveillance and resume treatment only upon progression. From then on, imaging was repeated every 3-4 months, and at the 1-year post-treatment scans a complete disappearance of mediastinal and liver lesions was observed, beyond that the residual LLL lesion was considered atelectatic.\nIn February 2019, concerns for recurrence in the LLL were raised due to the increase in size of the lung lesion with increased metabolic activity on a positron emission tomography scan. However, the patient still was completely asymptomatic. Two lung biopsies, one transbronchial and one transthoracic, were found to be completely negative for tumor cells; on the contrary, only signs of an acute inflammation (first biopsy) as well as a chronic inflammation (second biopsy) were detected. Further follow-up imaging showed that the lung lesion decreased in size to baseline, and the associated metabolic activity had resolved spontaneously. The patient remains in complete imaging remission to date, now 5-year post-treatment (Figure 1(a)). Circulating tumor mutations have been monitored using the Guardant360 platform (Guardant Health, Redwood City, CA, USA) over the last 4 years and the patient continues to present a circulating TP53 clone, although the percentage has been slowly decreasing (Figure 1(b)).", "gender": "Female" } ]
