Bacillus anthracis -
|
Anthrax is an endemic zoonosis in many countries; it causes human disease following inoculation of the spores of Bacillus anthracis. B. anthracis was the first bacterial pathogen described by Koch and the model pathogen for 'Koch's postulates' (see Box 6.1, p. 100). It is a Gram-positive organism with a central spore. The spores can survive for years in soil. Infection is commonly acquired from contact with animals, paicularly herbivores. The ease of production of B. anthracis spores makes this infection a candidate for biological warfare or bioterrorism. B. anthracis produces a number of toxins that mediate the clinical features of disease. The simple polychrome methylene blue (PMB) staining procedure for blood or tissue smears from dead animals (M'Fadyean reaction) established in 1903 remained accepted as a highly reliable, rapid diagnostic test for anthrax for six decades while that disease was still common in livestock throughout the world. Improvements in disease control led to anthrax becoming rare in industrialized countries and less frequent in developing countries with the result that quality controlled, commercially produced PMB became hard to obtain by the 1980s. Mixed results with alternative methylene blue-based stains then led to diagnosis failures, confusion among practitioners and mistrust of this procedure as a reliable test for anthrax. We now repo that, for laboratories needing a reliable M'Fadyean stain at sho notice, the best approach is to have available commercially pure azure B ready to constitute into a solution of 0.03 g azure B in 3 ml of 95% ethanol or methanol to which is then added 10 ml of 0.01% KOH (0.23% final azure B concentration) and which can then be used immediately and through to the end of the tests. Stored in the dark at room temperature, the shelf life is at least 12 months. Smears should be fixed with ethanol or methanol (95-100%), not by heat, and the stain left for 5 min before washing off for optimum effect. Ref Harrison20th edition pg 1078

Shift to right of oxygen dissociation curve is caused by all, EXCEPT:
|
Three impoant conditions affect the oxygen-hemoglobin dissociation curve: the pH, the temperature, and the concentration of 2,3-biphosphoglycerate (BPG; 2,3-BPG). A rise in temperature or a fall in pH shifts the curve to the right. When the curve is shifted in this direction, a higher PO2 is required for hemoglobin to bind a given amount of O2. Conversely, a fall in temperature or a rise in pH shifts the curve to the left, and a lower PO2 is required to bind a given amount of O2. A convenient index for comparison of such shifts is the P50, the PO2 at which hemoglobin is half saturated with O2. The higher the P50, the lower the affinity of hemoglobin for O2.

BCG is not given to patient with -
|
<p>BCG Aim- To induce a benign,aificial primary infection which will stimulate an acquired resistance to possible subsequent infection with virulent tubercle bacilli, and thus reduce the morbidity and moality from primary tuberculosis among those most at risk. WHO recommends the &;Danish 1331&; strain for vaccine production. Stable for several weeks at ambient temperature in a tropical climate and for upto 1 year if kept away from direct light and stored in a cool environment below 10 deg celcius. Vaccine must be protected from light ( wrapped up in a double layer of red/ black cloth). Normal saline is recommended as diluent for reconstituting the vaccine as distilled water may cause irritation. Reconstituted vaccine may be used within 3 hours. Dosage-0.1 mg in 0.1 ml volume. The dose of newborn below 4 weeks is 0.05 ml. Administered intradermally using tuberculin syringe. Injected slightly above the inseion of left deltoid. If injected too high / too low adjacent lymph nodes may become involved and tender. The vaccine must not be contaminated with an antiseptic/detergent. If alcohol is used to swab the skin , it must be allowed to evaporate before the vaccine is given. Phenomenon after vaccination:/ 2-3 weeks after a correct intradermal injection of a potent vaccine, a papule develops at the site of vaccination. It increases slowly in size and reaches a a diameter of about 4-8 mm in 5 weeks. It then subsides or breaks into a shallow ulcer but usually seen covered by a crust. Healing occurs within 6-12weeks leaving a permanent,tiny, round scar (4-8 mm in diameter).This is a normal reaction. Normally the individual become mantoux postive after 8 weeks has elapsed. Adverse reactions: prolonged severe ulceration at the site of vaccination, suppurative lymphadenitis, osteomyelitis and disseminated BCG infection. Contraindications: BCG should not be given to patients with generalised eczema, infective dermatosis, hypogammaglobulinemia , those with history of deficient immunity, patients under immunosuppressive treatment and in pregnancy. {Reference: park&;s textbook of preventive and social medicine, 23rd edition, pg no.196}</p>

Lipofuscin is an insoluble pigment, also know n as lipochrome or wear-and-tear pigment.
Lipofuscin is composed of polymers of lipids and phospholipids in complex with protein, suggesting that it is derived through lipid peroxidation of polyunsaturated lipids of subcellular membranes.
Lipofuscin is not injurious to the cell or its functions.
Its importance lies in its being a telltale sign of free radical injury and lipid peroxidation.
The term is derived from the Latin (fuscus, brown), referring to brown lipid. In tissue sections, it appears as a yellow-brown, finely granular cytoplasmic, often perinuclear, pigment.

Hypoglycemia in new born is seen in:a) IUGRb) Mother with hypothyroidismc) Rh incompatibilityd) Macrosomiae) Hyperthyroidism
|
Hypoglycemia is defined as blood glucose of less than 40 mg/dL, irrespective of the gestational age.
Causes of hypoglycemia Let us see each option one by one.
Option ‘a’ IUGR
“Hypoglycemia is due to shortage of glycogen reserve in the liver as a result of chronic hypoxia”
Dutta Obs. 6/e, p 465
Option ‘b’ Mother with hypothyroidism
Maternal hypothyroidism can cause hypoglycemia if it leads to fetal hypothyroidism also but “Maternal TSH receptor bloking antibodies can cross the placenta and cause fetal thyroid dysfunction.They however have little or no effect on fetal thyroid function even though they too cross the placenta.”.
Williams 23/e, p 1131, 1132
So according to latest editon of Williams, maternal hypothyroidism does not lead to fetal hypothyroidism, thus it does not cause fetal hypoglycemia.
Option ‘c’ Rh incompatibility
There is no definite correlation between Rhincompatibility and hypoglycemia.
Option ‘d’ Macrosomia
Macrosomia usually is due to maternal diabetes which inturn results in fetal hyperinsulinemia due to beta cell hyperplasia, which further results in neonatal hypoglycemia.
Dutta Obs. 6/e, p 287
Option ‘e’ Hyperthyroidism : Hyperthyroidism is a diabetes like state with increased insulin resistance.

Ans- B Interstitial brachytherapy Ref- Although this study is retrospective, the results are noteworthy, considering its long follow up and the description of results in terms of LCR, toxicities, and functional outcome. Our study recommends treating patients with brachytherapy alone in T1 stage and demonstrates the need for addressing nodal region either by neck dissection or nodal irradiation in T2 stage patients. The highlight of the study is that it establishes the need for dose escalation (from the doses used in the study) in both T1 and T2 stage tumors when using interstitial brachytherapy either as sole modality or as a boost.

Best treatment for meningioma with low recurrence rate is
|
The best treatment for meningioma of low recurrence rate is complete tumour resection including resection of underlying bone and associated dura. The constant principles in meningioma resection are the following: If possible, all involved or hyperostotic bone should be removed. The dura involved by the tumor as well as a dural rim that is free from tumor should be resected (duraplasty is performed). Dural tails that are apparent on MRI are best removed, even though some may not be involved with the tumor. Transaerial embolization has become a standard preoperative procedure in the preoperative management. Radiotherapy is mainly used as adjuvant therapy for incompletely resected, high-grade and/or recurrent tumors.

|
The co-transpo system may either be a sympo or an antipo. In sympo, (Fig. 2.12) the transpoer carries two solutes in the same direction across the membrane, e.g. sodium-dependent glucose transpoer (Chapter 8). Phlorhizin, an inhibitor of sodium-dependent co-transpo of glucose, especially in the proximal convoluted tubules of the kidney, produces renal damage and results in renal glycosuria. Amino acid transpo is another example for sympo.Ref: MN Chatterjea Textbook of Medical Biochemistry, 6th edition, page no: 17

First investigation to be done is Babygram (full body radiograph of the baby) to rule out duodenal atresia. Babygram is a full body radiograph of the baby, which shows the double bubble sign in duodenal atresia.The hallmark of duodenal obstruction is bilious vomiting without abdominal distention, which is usually noted on the 1st day of life. Peristaltic waves may be visualized early in the disease process. The diagnosis is suggested by the presence of a 'double-bubble sign' on plain abdominal radiographs. The appearance is caused by a distended and gas-filled stomach and proximal duodenum. Contrast studies are usually not necessary and may he associated with aspiration if attempted. Contrast studies may occasionally be needed to exclude malrotation and volvulus because intestinal infarction may occur within 6-12 hr if the volvulus is not relieved.'- Nelson 19/e p1278Duodenal AtresiaOccurs as a result of failure of vacuolization of the duodenum from its solid cord stageAnatomic variants of Duodenal AtresiaDuodenal stenosisMucosal web with intact muscular wall (windsock deformity)Two ends separated by a fibrous cordComplete separation with a gap within the duodenum.Associated Anomalies:Prematurity, Down syndrome, polyhydramniosQMalrotation, annular pancreas, biliary atresiaQCardiac, renal, esophageal, and anorectal anomaliesClinical Features:In most cases, the duodenal obstruction is distal to the ampulla of Vater, and infants present with bilious emesis in the neonatal periodQ.DiagnosisX-ray abdomen: Double-bubble sign (air-filled stomach and duodenal bulbQ).Diagnosis is confirmed, if there is no distal airQ.If distal air is present, an upper GI contrast study is performed rapidly, not only to confirm the diagnosis of duodenal atresia but also to exclude midgut volvulusQ.Treatment:Diamond-shaped duodenoduodenostomy is the treatment of choiceQSingle bubble signCongenital Hypertrophic Pyloric StenosisQDouble bubble signDuodenal atresiaQ, Annular pancreasTriple bubble signJejunal atresiaQ

The chest x-ray film is often, but not always, abnormal in patients with significant ASD. Cardiomegaly may be present from right hea dilation and occasionally from left hea dilation if significant mitral regurgitation is present in the patient with an ostium primum ASD. Right hea dilation is better appreciated in lateral films. The central pulmonary aeries are characteristically enlarged, with pulmonary plethora indicating increased pulmonary flow. A small aoic knuckle is characteristic, which reflects a chronically low systemic cardiac output state because increased pulmonary flow in these patients occurs at the expense of reduced systemic flow.(Ref: "Atrial Septal Defects in the Adult - Recent Progress and Overview".

Which complex in mitochondria is not involved in proton transpor during ETC ?
|
Ans. is 'b' i.e., Complex IIInner mitrochondrial membrane is impermeable to protons; therefore, proton pumps are required to pump protons (hydrogen ions) from mitochondrial matrix to the intermembrane space.The complex I (Site I), complex III (Site II) and complex IV (Site III) act as proton pumps ejecting protons (hydrogen ions) from the mitochondrial matrix to intermembrane space.Complex I (NADH-CoQ reductase) and complex III (CoQ - cytochrome c reductase) pump 4 protons each and complex IV (cytochrome c oxidase) pumps 2 protons.The concentration of hydrogen ions (protons) on the outer side of inner membrane becomes higher as compared to inner side.This results in generation of the electrochemical potential.Due to this electrochemical potential or proton motive force, the H+ ions ejected out (by proton pumps) flow back into the mitochondrial matrix down its electrochemical gradient through F0F1 ATPase molecule, which is also known as complex V of respiratory chain.This proton influx causes ATP synthesis. Fo components acts as channel for passage of hydrogen ions (Protons). F1 component possesses ATP synthase activity, which is switched on when the hydrogen ions pass through Fo component.

Ans. is 'a' i.e. Roseola infantum ParvovirusParvovirus is the smallest virus.It is a nonenveloped icosahedral virus with linear single stranded D.N.A.Pathogenesis of parvovirusParvovirus is highly tropic for human erythroid cells.The cellular receptors for parvovirus is blood group P antigen.P antigen is expressed on mature erythrocytes, erythroid progenitors, megakaryocytes, endothelial cells, placenta and fetal liver cells.Because of this distribution of Parvo virus receptors, the parvovirus replicates primarily in erythroid progenitors such as bone marrow and fetal liver cells and primarily causes diseases of these organs.Clinical manifestations:- Erythema infectiosum (fifth disease)Most B19 infections are asymptomatic.The main symptomatic manifestation of parvovirus is erythema infectiosum also known as fifth disease or slapped check disease.* Initially there is minor febrile prodrome and the classical facial rash develops after several days.Polyarthropathy syndromeUncommon among children but occurs in 50% of adults.Small joints of the hands and ankles are involved symmetrically.Aplastic crisisAsymptomatic transient reticulocytopenia occurs in most individuals with B19 infection.However in patients who depend on continuous rapid production of red cells, infections can cause transient aplastic crisis.In normal individuals with normal erythropoiesis few days of arrest of erythropoiesis will not cause detectable anemia.But, in cases which require continuous erythropoiesis such as cases of chronic hemolytic anemias (e.g. sickle cell anemia, hereditary spherocytosis) the life span of the R.B.C. is shortened. This leads to aplastic risis in these patients.Pure red cell aplasia/chronic anemiaParvovirus causes established persistent infection in patients with immunosuppression e.g. (AIDS, CLL).These patients have persistent anemia with reticulocytopenia.Hydrops fetalisParvovirus has tropism for fetal liver and heart. These tissues contain abundant P receptorsSo maternal infection with parvovirus pose a serious risk to the fetus resulting in hydrops fetalis and fetal death due to severe anemia.The risk of transplacental infection is 30% and the risk of fetal loss (early in 2nd trimester) is 9%.DiagnosisDiagnosis is done by the detection of B19 IgM antibodies.IqM is detected at the time of rash in erythema infectiosum and IgG is detected on the 7th day.TreatmentNo antiviral is effective against parvovirus.SPECTRUM OF DISEASE DUE TO B19 RELATED TO HOST FACTORSDiseaseHost* AsymptomaticNormal children and adults* Respiratory tract illnessNormal children and adults* Rash illnessNormal children and adults* Erythema infectiosum/fifthNormal childrendisease/ * slapped cheek syndrome * ArthralgiaNormal adults* Transient aplastic crisisPatients with increased erythropoiesis* Persistent anemiaImmuno deficient or compromised person* Congenital anemia/hydropsFetus < 20 weeks

The Hb level is healthy women has mean 13.5 g/dl and standard detion 1.5 g/dl, what is the Z score for a woman with Hb level 15.0 g/dI -
|
Ans. is 'd' i.e., 1.0 Thus the Z score for the woman in question is 1.0. Very simple funda to calculate Z score Normal variate indicates that the given observation is how many standard detion away from the mean. Here mean is 13.5 g/c11, SD is 1.5 g/dl and observation is 15 g/dl. That means observation (15 g/dl) is 1 SD (1.5 g/dl) away from mean (13.5 g/dl). So relative dete (Z-score) is 1. In same question, if we assume that the observed value is 16.5 (mean +- 2 SD) that means relative dete is 2 as the observed value is 2 SD away from mean.

Development of pellagra like skin lesion in carcinoid syndrome is due to:
|
One of the main secretory products of carcinoid tumors involved in the carcinoid syndrome is serotonin which is synthesized from tryptophan. Up to 50% of dietary tryptophan can be used in this synthetic pathway by tumor cells, and this can result in inadequate supplies for conversion to niacin; hence, some patients (2.5%) develop pellagra-like lesions.

How will you check the quantitative assessment of liver function -
|
The determination of the galactose elimination capacity with the method according to Tygstrup is the only test which detects the "functional hepatocyte mass" and thus constitutes a quantitative test for the metabolic function of the liver. In this determination of the maximum hepatic elimination capacity, differences with bilirubin, hemolysis and hyperlipidemia do not occur; reliable results are also obtained in disorders of hepatic secretion. Side-effects from the test substance galactose are not to be expected. It is also possible to determine galactose without difficulty in capillary blood. The i.v. galactose test permits an estimation of the degree of severity of liver diseases and can also be recommended for routine use in the investigation of specific hepatological questions.

Cold agglutinin disease (CAD): This designation is used for a form of chronic AIHA that usually affects the elderly. First, the term cold refers to the fact that the autoantibody involved reacts with red cells poorly or not at all at 37degC, whereas it reacts strongly at lower temperatures. As a result, hemolysis is more prominent the more the body is exposed to the cold. The antibody is usually IgM; usually, it has an anti-I specificity (the I antigen is present on the red cells of almost everybody)Harrison 19e pg: 659

Shoulder dystocia is suspected during a delivery after the delivery of the head, obstetrician asks the assistants to sharply flex the legs towards the abdomen. What is this maneuver?
|
The McRobes maneuverThe maneuver consists of removing the legs from the stirrups and sharply flexing the thighs up toward the abdomen. The procedure caused straightening of the sacrum relative to the lumbar veebrae, rotation of the symphysis pubis toward the maternal head, and a decrease in the angle of pelvic inclination. Although this does not increase pelvic dimensions, pelvic rotation cephalad tends to free the impacted anterior shoulder.Of rotational maneuvers, Woods (1943) repoed that by progressively rotating the posterior shoulder 180 degrees in a corkscrew fashion, the impacted anterior shoulder could be released. This is frequently referred to as the Wood's corkscrew maneuver. Rubin (1964) recommended two maneuvers. First, the fetal shoulders are rocked from side to side by applying force to the maternal abdomen. If this is not successful, the pelvic hand reaches the most easily accessible fetal shoulder, which is then pushed toward the anterior surface of the chest. This maneuver most often abducts both shoulders, which in turn produces a smaller bisacromial diameter. This permits displacement of the anterior shoulder from behind the symphysis With an all- fours maneuver , also called the Gaskin maneuver, the paurient rolls onto her knees and hands. Here, downward traction against the head and neck attempts to free the posterior shoulder The Zavanelli maneuver involves replacement of the fetal head into the pelvis followed by cesarean delivery Reference: William's obstetrics; 25th edition

Sclerostin is produced by?
|
Sclerostin (SOST) is a glycoprotein produced by osteocytes. They also synthesize receptor activator of nuclear factor kappa B ligand (RANKL). Both of these are involved in regulating bone formation and resorption. EXTRA EDGE: Romosozumab, a humanized monoclonal antibody that binds to sclerostin, prevents sclerostin from exeing this inhibitory effect. Therefore, in the presence of romosozumab, the Wnt signaling pathway is activated leading to bone formation and bone mineral density gain.

Which of the following is false about Digoxin
|
Refer kDT 7/e p516.. Medical useEdit Irregular heabeatEdit The most common indications for digoxin are atrial fibrillation and atrial flutter with rapid ventricular response, though beta blockers and/or calcium channel blockers are often preferred. There is tentative evidence that digoxin may increase the risk of death, though another meta-analysis in 2015 repoed no change in moality. Hea failureEdit Digoxin is no longer the first choice for hea failure; it has fallen out of or in people with hea failure because it may increase the risk of death. Currently, the recommendation for hea failure is a triple therapy of ACE inhibitor, beta blocker and mineralocoicoid antagonists. Digoxin is a third-line therapy. AboionEdit Digoxin is also used intrafetally or amniotically during aboions in the late second trimester and third trimester of pregnancy. It typically causes fetal demise(measured by cessation of cardiac activity) within hours of administration. Side effectsEdit Main aicle: List of side effects of digoxin Fuher information: Digoxin toxicity The occurrence of adverse drug reactions is common, owing to its narrow therapeutic index (the margin between effectiveness and toxicity). Gynaecomastia (enlargement of breast tissue) is mentioned in many textbooks as a side effect, thought to be due to the estrogen-like steroid moiety of the digoxin molecule, but when systematically sought, the evidence for this is equivocal as of 2005. The combination of increased (atrial) arrhythmogenesis and inhibited atrioventricular (AV) conduction (for example paroxysmal atrial tachycardia with AV block - so-called "PAT with block") is said to be pathognomonic(that is, diagnostic) of digoxin toxicity.

Ans. is 'b' i.e., DMSAo For imaging of renal cortex Tc-99m-DMS A is used,o Other three agents (of options) are used for dynamic renal scintigraphy.Renal scintigraphy1) Static renal scintigraphyFor static renal scintigraphy Tc - 99m - DMSA (Dimercaptosuccinic acid) is used. DMSA is cleared by renal tubules. When DMSA is labeled with Tc - 99 and injected intravenously, it can be used to create an image of the renal cortex which reflects vascular flow and tubular function. It is called static scintigraphy because radiopharmaceutical is tubularly fixed in the renal cortex.Beside Tc - 99m - DMSA, other radiopharmaceuticals used for static scintigraphy are Tc - 99m - glucoheptone, (Tc-GH)Indications for static renal scintigraphy (Tc - 99m - DMSA) >Assessment of individual functionInvestigation of UTI (particularly in children)A ssessment of reflux nephropathy (scars)Space occupying lesions (cortical mass)Investigation of horse shoe, solitary or ectopic kidney2) Dynamic renal scintigraphy (functional imaging)For dynamic renal scintigraphy Tc - 99m - DTPA (Diethylene triamine pentaacetic acid) and Tc - 99m - MAG3 (mercaptoacetyltriglycine) and I-123-OIH (O - iodohippurate) are used.Tc - 99m - DTPA is filtered completely by the glomerulus but are not reabsorbed, metabolized or secreted by renal tubules. Therefore this agent can be used to measure GFR.Tc - 99m - MAG3 and I - 123 - OIH are secreted by renal tubules. These are used to determine effective renal plasma flow.Tc - 99m - MAG3 is the best (amongst three) for dynamic renal scintigraphy, but is costly.This is called dynamic scintigraphy because tracers are readily transported either by glomerulus or renal tubules (in contrast to static scintigraphy, where tracer is tubularly fixed in the renal cortex).Indications of dynamic renal scintigraphyi) Diagnosis of obstructed vs non - obstructed dilatationiv) Demonstration of vesico-urethral refluxii) Diagnosis of renal artery stenosisv) Assessment of renal transplantationiii) Assessment of perfusion in ARFvi) Renal trauma
