c54ace25-5da5-4215-ab7d-a38109f67af4 | Osmotic fragility is increased in ? | Sickle cell anaemia | Thalassemia | Hereditary spherocytosis | Chronic lead poisoning | 2c
| single | Ans. is 'c' i.e., Hereditary spherocytosis Osmotic fragility of Red blood cells. Red blood cell osmotic fragility is the resistance of RBC hemolysis to osmotic changes. o Normally RBC maintains osmotic equilibrium with the surrounding medium i.e., with serum that has 0.9% NaCl. o As the surrounding medium becomes hypotonic fluid will enter into the cell along osmotic gradiant, eventually under very hypotonic conditions the cell will enlarge to capacity and rupture -4 Osmotic lysis. Osmotic fragility is determined by measuring the degree of hemolysis in hypotonic saline. o Normal red cell begins to lyse at 0.5% NaC1 and the hemolysis is complete at 0.3 NaCl. o Red blood cells osmotic fragility is considered to be increased if hemolysis occur in a NaC1 concentration > 0.5%. o Osmotic fragility is considered to be decreased if the hemolysis is not complete in a 0.3% of NaCl. Increased osmotic fragility o Hereditary spherocytosis o Hemolytic anemia (acquired immune) o Malaria o Severe pyruvate kinase dificiency o Hemolytic disease of newborn Decreased osmotic fragility o Iron deficiency anemia Thalassemia Liver disease Reticulocytosis o Hemoglobinopathies, MS, HbC. | Pathology | null |

| single | Ans. is 'a' i.e., Fenoldopam Summary And Recommendations for prevention of contrast induced nephropathy (uptodate recommendation )o Optimal therapy to prevent contrast-induced acute renal failure remains uncertain. Patients with near-normal renal function are at little risk and few precautions are necessary other than avoidance of volume depletion.o We recommend the following preventive measures for patients at increased risk of contrast nephropathy, which is defined a serum creatinine >1.5 mg/dL (132 micromol/L) or an estimated glomerular filtration rate <60 ml/l 73 m2, particularly in those with diabetes.o Use, if possible, ultrasonography, MRI without gadolinium contrast, or CT scanning without radiocontrast agents.o We recommend NOT using high osmolal agents is not recommendedo We recommend the use of iodixanol or nonionic low osmolal agems such as iopamidol or ioversol rather than iohexol.o Use lower doses of contrast and avoid repetitive, closely spaced studies.o Avoid volume depletion and nonsteroidal anti-inflammatory drugs.o If there are no contra indications to volume expansion, we recommend isotonic intravenous fluids prior to and continued for several hours after contrast administration. The optimal type offluid and timing of administration are not well established. We suggest isotonic bicarbonate rather than isotonic saline.o Despite conflicting data, we suggest that acetylcysteine be administered the day before and the day of the procedure, based upon its potentialfor benefit and low toxicity and cost. If acetylcysteine is administered, we suggest giving 1200 mg orally twice daily rather than 600 mg twice daily the day before and the day of the procedure.o Based upon the lack of convincing evidence of benefit and ihe potential risk of anaphylactoid reactions, we suggest not using intravenous acetylcysteine for the prevention of contrast nephropathy. (Note: Oral acetylcysteine is used)o We recommend NOT using mannitol or other diuretics prophytactically.o Among patients with stage 3 and 4 CKD, we recommend NOTperforming prophylactic hemofiltration or hemodialysis after contrast exposure.o Among patients with stage 5 CKD, we suggest prophylactic hemodialysis after contrast exposure if there is already a functioning hemodialysis access. | Medicine | Drugs |

6ced785b-413c-4df8-8ce8-aa579c6d9521 | What is the treatment of threshold ROP? | laser photocoagulation | slow reduction in oxygen | retinal reattachment | antioxidants | 0a
| single | Ans is 'a' i.e. Laser Photocoagulation Threshold disease in ROP is defined as stage 3+ ROP in Zones 1 or 2 occupying at least five contiguous clock-hours or eight noncontiguous clock-hours of retina.Treatment of threshold disease is Laser Photocoagulation.'Laser therapy has largely replaced cryotherapy because visual and anatomical outcomes are superior and laser induces less myopia. " -Kanski 6/e p610Other options:Antioxidants like vit E and slow reduction in 02 has no role in established ROP (threshold disease in our patient); although both are mentioned in few texts for prevention of ROP and even that is not well proven.Retinal reattachment is required when retina is detached like in stage 4 and 5 while Threshold disease is Stage 3 + disease.Also know:"Low birth weight and decreased gestational age are now considered the primary causative factors for ROP. Supplemental oxygen administration which was for a long time considered as the important causative factor is now considered only a risk factor. " - Khuran Ophthalmology 4/e p264 "ROP is confined to those with a birth weight of under 1.5 kg and/or a gestational age of under 32 wks. "- Parson 21/e P310 The hallmark of retinopathy of prematurity (ROP) is abnormal retinal vasculature. Ophthalmologists diagnose and make decisions about the initial treatment of ROP based on the appearance of the retinal blood vessels. Dilatation and tortuosity of the retinal vessels at the posterior pole is termed 'plus' disease. It is a sign of rapidly progressive ROP and is an indication for early laser ablation of the peripheral avascular retina.Retinopathy of prematurity (ROP)ROP is a bilateral proliferative retinopathy that develops in premature infants due to incomplete vasculogenesis of retina at the time of birth.During normal retinal development, vessels migrate from the optic disc to the ora serrata beginning at 16weeks of gestation. Capillary network is formed differentiating into mature vessels which extend to nasal ora by 36 wks and tangential ora by 39-41 wks.The pathogenesis of ROP begins with premature birth. Exposure of extrauterine environment causes phases of hyperoxia-vasocessation (obliteration of retinal vessels) and hypoxia-Vaso proliferation (neovascularization). VEGF is thought to be the most important molecule involved in the neovascularization.Neovascularization leads to retinal and vitreous changes which ultimately lead to retinal detachment.Classification of ROP:ROP is described using a number of parameters. These are location of the disease into zones (1, 2, and 3), the circumferential extent of the disease based on the clock hours (1-12), the severity of the disease (stage 1-5) and the presence or absence of "Plus Disease".Classification on the basis of severity, ROP is divided into 5 stages:-Stage I- the first sign of ROP (stage 1) is the appearance of a thin, fiat, white structure (termed a demarcation line) at the junction of vascularized retina posteriorly and avascular retina anteriorly.Stage II- the demarcation line develops into a pink or white elevation (ridge) of thickened tissueStage III- proliferation of vessels over the ridge and into vitreous (extra vitreal fibrovascular proliferation)Stage IV- partial retinal detachmentIVa- partial detachment with macular sparing IVb- partial detachment with macula involvedStage V- total retinal detachmentClassification on basis of anatomical location:-Since there is a direct correlation between severity of disease and amount of avascular retina, the location of the border between vascularized and avascular retina is an important prognostic sign.3 zones are divided to describe the location of ROP. Location of the border in zone 1 is the most severe disease and in zone 3 least.Zone 1 is defined as a circle, the center of which is the disc, and the radius of which is twice the distance of the disc to the fovea.Zone 2 is a doughnut-shaped region that extends from the anterior border of Zone 1 to within one disc-diameter of the ora serrata nasally and to the anatomic equator temporally.Zone 3 encompasses the residual temporal retina.Plus disease:- As ROP progresses, more and more shunting occurs in the neovascular tissue at the retinal vascular- avascular junction. This increased retinal vascular blood flow results in dilation and tortuosity of the major retinal arteries and veins in the posterior pole - described as "plus disease". Plus disease is the hallmark of rapidly progressive ROP and is notated by adding a plus sign after the number of the ROP stage.Management:Most of the cases (approx. 80%) of ROP resolve spontaneously, hence intervention is chosen according to the below given protocol.ROP is divided into Threshold and Pre threshold disease.Threshold disease: It is defined as stage 3+ ROP in Zones 1 or 2 occupying at least five contiguous clock-hours or eight noncontiguous clock-hours of retina.Treatment of Threshold disease is - Laser photocoagulation.Pre threshold disease is divided into 2 types:High risk or Type I - treatment is Laser photocoagulationLow risk or Type II - treatment is Weekly or Twice weekly observationType 1 Pre thresholdType 2 Pre thresholdZone I ROP (any stage) + Zone I, Stage 3 Zone II, Stage 2/3 +Zone I, Stage 1/2 - Zone II, Stage 3 -Laser PhotocoagulationWeekly or Twice weekly observationROP diseases less severe than Pre threshold are followed up.In this question, the child with zone 1, stage II 'plus' ROP falls into Pre threshold disease- Type 1 or high risk type, hence Laser Photocoagulation would be the management of choice. | Ophthalmology | Dystrophies and Degenerations |

9f78aa57-fa01-4142-8b6b-0c29dd2d57ba | Increased osmotic fragility is characteristic of:September 2009 | Hereditary spherocytosis | Sickle cell anemia | Thalassemia | Iron deficiency anemia | 0a
| single | Ans. A: Hereditary spherocytosisThe normal red blood cell is a relatively impermeable biconcave disc which maintains osmotic equilibrium with the surrounding medium. As the surrounding medium becomes hypotonic, fluid will be taken into the cell to maintain stability. Eventually under very hypotonic conditions the cell will fill to capacity and rupture. Spherocytic red blood cells have a decreased capacity to expand, and will rupture in mildly hypotonic conditions that fail to lyse normal red cells. They thus exhibit increased osmotic fragility.Osmotic fragility is determined by measuring the degree of hemolysis in hypotonic saline solution. With the unincubated test, red cell osmotic fragility is considered to be increased if hemolysis occurs in a sodium chloride concentration > 0.5%. Although increased osmotic fragility is characteristically associated with hereditary spherocytosis, it may also be increased in other types of hemolytic anemia associated with the presence of spherocytes, paicularly auto-immune hemolytic anemia, and in hypernatermia (Na > 155 meq/L).Often the increased osmotic fragility in spherocytosis is limited to a small fraction of cells that are unusually susceptible to lysis. After incubation, the defect is magnified, and a striking increase in fragility will be seen in hereditary spherocytosis. Osmotic fragility is considered to be decreased if hemolysis is not complete in a 0.30% NaC1 solution. Decreased osmotic fragility is associated with chronic liver disease, iron deficiency anemia, thalassemia, hyponatremia (Na < 130 meq/ L), polycythemia vera, and sickle cell anemia after splenectomy. | Pathology | null |
999fae05-0f74-4b1a-b0c2-4144fd410e04 | A three year old child is brought to the emergency depament having just ingested a large overdose of an antihistaminic drug. This drug is a weak base capable of entering most tissues including the brain. On physical examination the hea rate is 100/ minute, blood pressure is 110/60 mm Hg and the respiratory rate is 20/ minute. In this case of poisoning: | Urinary excretion would be accelerated by administration of NH4Cl, an acidifying agent | Urinary excretion would be accelerated by administration of NaHCO 3, an alkalinizing agent | More of the drug would be ionized at blood pH than at stomach pH | Absorption of the drug would be faster from the stomach than from the small intestine. | 0a
| multi | This question can be solved by the knowledge that basic drugs are ionized in the acidic medium and vice-a-versa. This antihistaminic drug is a weak base and will be highly ionized in the acidic urine. As ionized drugs cannot be reabsorbed in the nephron, urinary acidifying agents like NH4Cl will accelerate the excretion of this agent. On the other hand, NaHCO3 will decrease its excretion by increasing the unionized form. Blood pH is slightly alkaline (7.4) whereas gastric pH is highly acidic. Basic drugs are ionized more in the acidic pH, therefore option (c) is false. Only unionized molecules can cross the membranes, therefore more drug will be absorbed by the small intestine (alkaline pH). | Pharmacology | Histamine, 5-HT and PGs |

Aetiology and pathogenesis
Acute respiratory distress syndrome (ARDS) is a diffuse neutrophilic alveolitis caused by a range of conditions and characterised by bilateral radiographic infiltrates and hypoxaemia. Activated neutrophils are sequestered into the lungs and capillary permeability is increased, with damage to cells within the alveoli. The pathophysiology is part of the inflammatory spectrum, and the triggers are similar: infective and non-infective inflammatory processes. These processes result in exudation and accumulation of protein-rich cellular fluid within alveoli and the formation of characteristic ‘hyaline membranes’. Local release of cytokines and chemokines by activated macrophages and neutrophils results in progressive recruitment of inflammatory cells. Secondary effects include loss of surfactant and impaired surfactant production. The net effect is alveolar collapse and reduced lung compliance, most marked in dependent regions of the lung (mainly dorsal in supine patients).
The affected airspaces become fluid-filled and can no longer contribute to ventilation, resulting in hypoxaemia (due to increased pulmonary shunt) and hypercapnia (due to inadequate ventilation in some areas of the lung): that is, ventilation–perfusion mismatch.

| single | All clinical features are suggestive of malignant otitis externa, an inflammatory condition of the external ear. Malignant otitis externa (also k/a Necrotizing external otitis) Malignant otitis externa is an inflammatory condition of the external ear usually spreading deep to cause osteomyelitis of temporal bone and base of skull. It occurs primarily in immunocompromised persons, especially older persons with diabetes mellitus, and is often initiated by self-inflicted or iatrogenic trauma to the external auditory canal [May also be seen in pts. who received radiotherapy to skull base I The most frequent pathogen is Pseudomonas aeruginosa. Others may be S. aureus, Staphylococcus epidermidis, Aspergillus, Actinomyces, and some gram-negative bacterial. One of the hallmarkof malignant otitis externs is granulation tissue in the external auditory canal, especially at the hone-cailage junction. As the infection spreads to the temporal bone, it may extend into the cranium and result in cranial nerve palsies (commonly the facial nerve) Cranial nerve involvement indicates poor prognosis. Death is usually due to intracranial complications such as sigmoid sinus thrombosis. It has high moality rate due to which the name 'malignant' is used for this disease. Treatment Includes correction of immunosuppression (when possible), local treatment of the auditory canal, long-term systemic antibiotic therapy, and in selected patients, surgery. - In all cases, the external ear canal is cleansed and a biopsy specimen of the granulation tissue sent for culture. - IV antibiotics is directed against the offending organism. - For Pseudomonas aeruginosa, the most common pathogen, the regimen involves an antipseudomonal penicillin or cephalosporin (3rd generation-piperacillin or ceftazidime) with an aminoglycoside. A fluoroquinolone antibiotic can be used in place of the aminoglycoside. Ear drops containing antipseudomonal antibiotic e.g. ciproflaxacin plus a glucocoticoid is also used. - Early cases can be managed with oral and otic fluoroquinolones only. - Extensive surgical debridement once an impoant pa of the treatment is now rarely needed. | ENT | null |

99556d84-5417-4ac7-8975-f746b36805a5 | Digoxin toxicity may result from the concurrent administration of digoxin with all of the following drugs EXCEPT | Quinidine | Hydrochlorothiazide | Triamterene | Furosemide | 2c
| multi | Triamterene is a potassium-sparing diuretic that may protect against diuretic-induced digoxin toxicity. Digoxin toxicity may be caused by drugs that increase serum digoxin levels or increase the binding of digoxin to its receptor, the sodium-potassium adenosine tn phosphatase (ATPase). Quinidine decreases digoxin volume of distribution and clearance. Verapamil also decreases the clearance of digoxin. Both drugs may
thereby increase serum digoxin levels and precipitate digoxin toxicity. Diuretics (e.g., hydrochlorothiazide, furosemide) may cause hypokalemia and hypomagnesemia, both of which may predispose to cardiac arrhythmias. Furthermore, hypokalemia increases di-goxin binding to sodium-potassium ATPase. | Unknown | null |

4992644f-8c52-437d-8c4e-4936560776ac | A 3-year-old male has come for a routine dental check up. Intra-oral examination reveals good oral hygiene and open proximal contacts. During previous dental appointments, he was cooperative. Which radiographic assessment should be done for this patient? | No radiographic assessment. | Bitewing Radiographs | Intraoral periapical radiograph | Occlusal radiographs | 0a
| single | The American Dental Association (ADA), the American Academy for Pediatric Dentistry (AAPD), the European Academy for Pediatric Dentistry (EAPD), and other organizations have published criteria that are meant to guide the dental professional in decision-making regarding appropriate radiographic imaging (Table 2-5). These guidelines clearly state that if the patient cannot cope with the procedure, one should attempt other strategies to handle the situation. The guidelines all acknowledge that, in some cases, radiographs are not possible, in which case, one should balance the benefit against the risk even more carefully. Sometimes it is better to postpone the radiographic exposure until the patient is older or better conditioned. The guidelines also clearly state that if there are no clinical signs of pathology, the need for a radiographic assessment is up to the professional’s judgment, and that these decisions have to be made on an individual patient basis. Radiographs are never to be used for economic and screening reasons since they involve a potential health risk for the patient. A 3-year-old with a sound dentition and open proximal contacts does not need a radiographic assessment. In contrast, for a 3-year-old with only 10 teeth visible in the mouth and no history of dental treatment, the dental professional should make a radiographic assessment. If a 4-year-old shows rampant decay, a radiographic assessment is certainly justifiable and indicated. | Dental | null |

| single | The follicle that ruptures at the time of ovulation promptly fills with blood, forming what is sometimes called a corpus hemorrhagicum. Minor bleeding from the follicle into the abdominal cavity may cause peritoneal irritation and fleeting lower abdominal pain ("mittelschmerz"). The granulosa and theca cells of the follicle lining promptly begin to proliferate, and the clotted blood is rapidly replaced with yellowish, lipid-rich luteal cells, forming the corpus luteum.

| single | Ans. is 'a' i.e., K ATP channel blocker * Sulfonylurease provoke a brisk release of insulin from pancreas. They act on the so called "Sulfonylurea receptors" (SUR1) on pancreatic b-cell membrane - cause depolarization by reducing conductance of ATP sensitive K+ channels. This enhances influx of Ca+2 - degranulation. They do not cause hypoglycemia in pancreatectomized animals and type 1 diabetes (Presence of at least 30% of functional b-cells in essential for their action). A minor action reducing glucagon secretion by increasing insulin and somatostatin release has been demonstrated. | Pharmacology | Endocrinology |
