1a364881-49a8-4d39-8a9f-ec3017a6d14b | A 30 yr old male presents to the OPD with Erectile dysfunction. Basic screening evaluation is unremarkable. Which of the following should be the next step in the evaluation/management of this patient? | Cavernosometry | Neurological testing | Oral Sildenafil citrate trial | Penile ultrasound doppler study | 2c
| multi | Specialised investigations such as Penile Doppler Ultrasound, Dynamic Infusion Cavernosography and Neurological testing are rarely necessary in the evaluation of Erectile Dysfunction. These investigations are indicated in selected complicated cases and are not indicated for the initial evaluation of Erectile Dysfunction. So the most appropriate next step in management in this patient would be a trial of oral phosphodiesterase type 5 inhibitor sildenafil. Evaluation of a patient with sexual dysfunction involves taking thorough history and performing physical examination. Basic laboratory investigations done includes estimation of CBC, lipid profiles, serum prolactin and testosterone. Additional diagnostic testing is rarely necessary in the evaluation of erectile dysfunction. Specialized test involves (1) studies of nocturnal penile tumescence and rigidity, (2) vascular testing (in-office injection of vasoactive substances, penile Doppler ultrasound, penile angiography, dynamic infusion cavernosography/cavernosometry), (3) neurologic testing (biothesiometry-graded vibratory perception, somatosensory evoked potentials), and (4) psychological diagnostic tests.

| single | The transmission of HIV from mother to infant has decreased in recent years, due in large part to perinatal administration of antiretroviral medications to the mother and a course of zidovudine to the exposed infant. Studies suggest that a better than 50% decrease in transmission can be seen with appropriate medications as outlined.IVIG has not been shown to have a role in decreasing perinatal transmission. Healthy asymptomatic term infants born to HIV-infected mothers do not need special monitoring, nor do they need routine radiographs.An HIV ELISA is an antibody test and will be positive in the infant born to an HIV-infected mother due to maternal antibodies that are passed through the placenta; it is not a useful test in the newborn infant to determine neonatal infection because of this expected transfer of maternal (and not infant) immunoglobulin. The confirmatory Western blot also assays for antibodies to HIV and is similarly unhelpful in the newborn period. | Pediatrics | New Born Infants | [

| multi | Pancuronium consists of a steroid ring on which two modified ACh molecules are positioned. It resembles ACh enough to bind (but not activate) the nicotinic ACh receptor. Rocuronium undergoes no metabolism and is eliminated primarily by the liver and slightly by the kidneys. Because of its unique metabolism, atracurium's duration of action can be markedly prolonged by hypothermia and to a lesser extent by acidosis. Vecuronium is metabolized to a small extent by the liver. It depends primarily on biliary excretion and secondarily (25%) on renal excretion. Although it is a satisfactory drug for patients with renal failure, its duration of action is somewhat prolonged. Ref: Butterwoh IV J.F., Mackey D.C., Wasnick J.D. (2013). Chapter 11.

Which of the following drugs would be appropriate in his case? | Amlodipine | Spironolactone | Propranolol | Hydrochlorthiazide | 0a
| multi | Answer: a) Amlodipine* Amlodipine is a dihydropyridine-type calcium channel blockers. Dihydropyridine calcium channel blockers (amlodipine) do not have contraindications related to renal impairment or potassium levels and can be safely administered in patients with asthma.* Hydrochlorothiazide is metabolized by the kidney, so it would not be a good choice in this patient as there is renal impairment (as indicated by elevated creatinine), because the drug itself can aggravate renal failure.* Spironolactone is a potassium-sparing diuretic.

It is chemically similar to tamoxifen Clomiphene is a non steroidal triphenylethylene derivative which demonstrates both estrogen agonist and antagonist propeies (predominant). It is the agent of choice for women with oligomenorrhea or amenorrhea having sufficient ovarian function to maintain estrogen at a serum level of 40pg/ml. Patient selection : Normal gonadotropicdeg normoprolactinemicdeg patients with normal cycle with absent or infrequent ovulation.deg PCOSdeg Post pill amenorrhea.deg Dose : Initial dose of 25 to 50mgdeg is given daily from D2 - D 5. Ovulation is expected to occur about 5 - 7 days after the last day of therapy. If ovulation doesnot occur, dose is increased in 50mg steps to a maximum of 250mg daily. (Although doses > 100 mg /day are not approved by FDA). Therapy is in given for 4-6 cycles. Clomiphene will be successful in inducing ovulation in about 70% of women, with ovaries producing estrogen Switch over from clomiphene to more aggressive therapy is done when : There is no response to clomiphenedeg (even with 100 mg / day dosing). There is ovulatory response to clomiphene but no pregnancydeg (following 3 to 6 months of ovulatory response to clomiphene). Patients with pituitary insufficiencydeg These patients usually respond to Gonadotropins. Note : Letrozole - 2.5mg (non steroidal aromatase inhibitor) is found superior to clomiphene. 2. Gonadotropin therapy : Prerequisite for Gonadotropin therapy : Ovarian reserve must be present. The Gonadotropins used are Human menopausal Gonodotropin : -- It is a formulation containing equal amounts of FSH and LH (751U each). -- It is prepared from hormones obtained from urine of postmenopausal women. HCG is required as an ovulatory trigger. FSH : purified urinary FSH and Recombinant FSH are also available. 3. Gonadotropin releasing hormone : Pulsatile GnRH : If other methods have failed then pulsatile GnRH is needed in patients with anovulation and hypothalamic insufficiency. Other drugs which can be used to for ovulation : Bromocriptine/Cabergoline : Are used to to treat anovulation caused by increase in serum prolactin level. Coicosteroids : Use to treat anovulation due to congenital adrenal hyperplasia. Also know : Mangement of unilateral proximal tubal block : Hysteroscopic cannulation or microsurgical tubo cornual anastomosis (if any periadenaxal adhesions are also present). Management of distal tubal block : Best is IVF. Surgical procedures like fimbrioplasty (lysis of fimbrial adhesions or dilatation of fimbrial stenosis) or neosalpingostomy may be done. Management of distal tubal block by hydrosalperix First laparoscopic salpingectomy followed by IVF Management of Bipolar tubal obstruction i.e. both proximal and distal tubal obstruction.

| single | Ans. is 'd' i.e., Neuro-muscular junction* Vecuronium, a non-depolarizing blocker, acts on nicotinic receptors at myoneural junction.* Neuro-muscular blocker act at myoneural junction1. Competitive (Non-depolarizing) blocker: -# They compete with Achfor Nm receptors - called competitive blockers. They prevent binding of Ach to Nm receptors - No opening of Na+ channels - No depolarization, so these are called non-depolarizing blockers. Competitive blockers reduce the frequency of channel opening but not its duration or the conductance of a channel once it has opened. When the magnitude of end plate potential falls below a critical level, it is unable to trigger propagated muscle action potential - muscle fails to contract. Neostigmine (anticholinesterases) antagonises competitive blockers as it increases the concentration of Ach by inhibiting its degradation by cholinesterase. Therefore, Neostigmine is used for the reversal of competitive (nondepolarizing) blockers.2. Depolarizing blockers (Succinylcholine, Decamethonium)# Depolarizing blockers have affinity as well as submaximal intrinsic activity on NM receptors. They depolarize muscle end plates by opening of Na+ channels and initially produce twitching and fasciculations (not full contraction as these drugs have submaximal activity) - So, they are called depolarizing blocker. These drugs do not dissociate rapidly from the receptor (NM) - Persistant partial depolarization - Na+ channels get inactivated - flaccid paralysis. Neostigmine does not antagonize depolarising blockers (Therefore neostigmine cannot be used for reversal).Inf act neostigmine can potentiate the block as neostigmine and other anti-cholinesterase also inhibits pseudocholinesterase which metabolizes Sch.Under certain conditions depolarizing agents produce dual mechanism of neuromuscular blockade which can be divided into two phases :a) Phase I block* Rapid in onset* Result from persistant depolarization of muscle end plate - Typical mechanism of action of depolarizing blocker.* Has classical features of depolarization block.* Block is not antagonized by anticholinesterases (neostigmine).b) Phase II block (Dual block)* Slow in onset* Results from desensitization of receptor to ACh - Ach can not act on Nm receptors (similar to competitive blocker).* Resembles block produced by competitive blockers - Therefore, has characteristics similar to non-depolarizing (competitive) block.* Block is partially reversed by anticholinesterases (Neostigmine).# In man, normally, only phase I block is seen - typical depolarizing block.# Phase II block is seen when fluorinated anaesthetics have been given or when SCh is injected in high dose.# SCh also produces phase II block in patients with atypical or deficient pseudocholinesterase. | Anaesthesia | Muscle Relaxant | [

| multi | Most guides have given option a as the answer.
I have done extensive search on this. First you see the topical adverse effects of parasympathomimetic antiglaucoma drugs (from yanoff & Duker) :-
Directly acting (cholinergic agonists like pilocarpine, carbachol) → Miosis, uveitis, browache, cataracts, myopia, retinal detachment, colour vision changes, angle closure, ocular cicatracial pemphigoid.
Indirectly acting (anticholineesterases like demecarium) :- Intense miosis, iris pigment cysts, punctal stenosis, myopia, cataract, retinal detachment, angle closure.
Now see each option sequentially :-
Option '1'
Pilocarpine can cause shallow anterior chamber :-
"The use of pilocarpine is somewhat paradoxical since it is known to cause further shallowing of anterior chamber".
— Evidence - based ophthalmology.
Now you must be thinking then why pilocarpine is the drug of choice for angle closure glaucoma. Pilocarpine works by helping to open the angle by tensing the iris-diaphragm and pulling on the scleral spur. It may also help to resolve relative pupil block.
Option '2'
Punctal stenosis is caused by indirect cholinomimetic (cholinesterase) not by direct cholinomimetic (pilocarpine).
Option '3'
Rarely, pilocarpine can cause follicular conjunctivitis :-
"Pilocarpine and carbachol may both cause conjunctival follicle".
— Clinical ophthalmology.
Option '4'
Miotics (pilocarpine) makes the iris thin and pulls it away from lens removing the pupillary block, increasing the chances of posterior synechiae (due to stretching & increased surface of iris) and restoring aqueous flow by opening irido-corneal angle. | Ophthalmology | null | [

| single | Fetal exposure to an antibiotic depends on many factors such as gestational age, protein binding, lipid solubility, pH, molecular weight, degree of ionization, and concentration gradient. Some antibiotics are even concentrated in the fetal compartment. Tetracycline is contraindicated in all three trimesters. It has been associated with skeletal abnormalities, staining and hypoplasia of budding fetal teeth, bone hypoplasia, and fatal maternal liver decompensation. Sulfonamides are associated with kernicterus in the newborn. They compete with bilirubin for binding sites on albumin, thereby leaving more bilirubin free for diffusion into tissues. Sulfonamides should be withheld during the last 2 to 6 weeks of pregnancy. With prolonged treatment of tuberculosis (TB) in pregnancy, streptomycin has been associated with fetal hearing loss. Its use is restricted to complicated cases of TB. Nitrofurantoin can cause maternal and fetal hemolytic anemia if glucose- 6-phosphate dehydrogenase deficiency is present. Chloramphenicol is noted for causing the gray baby syndrome. Infants are unable to properly metabolize the drug, which reaches toxic levels in about 4 days and can lead to neonatal death within 1 to 2 days. | Gynaecology & Obstetrics | Fetus & New Born and their Diseases | [
