Ans. is 'c' i.e., Pyloric stenosisDiagnosis of congenital hyperophic pyloric stenosis o History of vomiting without bile (nonbilious vomiting).o Physical examination ?i) Palpable mass in the epigastriumii) After feeding, visible gastric peristatic wave that progresses across the abdomen.USG confirm the diagnosis Criteria --> Pyloric thickness > 4 mm or an overall pyloric length > 14 mm.o Contrast studies ?i) Shoulder sign A bulge of the pyloric muscle into the antrum.ii) Double tract sign -> Parallel streaks of barium in the narrowed channel.iii) Elongated pyloric channel.So the boy is having pyloric stenosis. The only problem is age of boy i.e 6 yrs. The hyperophic pyloric stenosis which we know of, makes its clinical presentation in early infancy (3rd to 6th weeks of life)o But the problem in solved once you know that there is a similar disease in adults - Hyperophic pyloric stenosis of adults.

Ref:Harsh Mohan - Textbook of Pathology, 6th Edition.page no.462 BRONCHOPULMONARY SEQUESTRATION Sequestration is the presence of lobes or segments of lung tissue which are not connected to the airway system. The blood supply of the sequestered area is not from the pulmonary aeries but from the aoa or its branches. Sequestration may be intralobar or extralobar. Intralobar sequestration is the sequestered bronchopulmonary mass within the pleural covering of the affected lung. Extralobar sequestration is the sequestered mass of lung tissue lying outside the pleural investing layer such as in the base of left lung or below the diaphragm. The extralobar sequestration is predominantly seen in infants and children and is often associated with other congenital malformations.

absorption by lymphatics "A negative force is always required on the outside of the lungs to keep the lungs expanded. This is provided by negative pressure in the normal pleural space. The basic cause of this negative pressure is pumping of fluid from the space by the lymphatics (which is also the basis of the negative pressure found in most tissue spaces of the body)."- Guyton 11/e p489 The intrapleural pressure is usually about -7 mm Hg (a few millimeters of mercury more negative than the collapse pressure of the lungs).

In lens, the enzyme aldose reductase reduces monosaccharides to corresponding sugar alcohols; glucose to sorbitol and galactose to galactitol. POLYOL PATHWAY OF GLUCOSE - Sorbitol is very poorly absorbed from intestine. It involves the reduction of glucose by aldose reductase to sorbitol, which can then be oxidized to fructose. This would amount to the interconversion of glucose to fructose. Glucose when conveed to sorbitol, cannot diffuse out of the cell easily and gets trapped there. Sorbitol is normally present in lens of eyes. But in diabetes mellitus, when glucose level is high, the sorbitol concentration also increases in the lens. This leads to osmotic damage of the tissue and development of cataract. Galactitol also causes cataract. REF: DM VASUDEVAN TEXTBOOK OF BIOCHEMISTRY, SIXTH EDITION, PG.NO.,119,588.

Adipocytes (Ref: Harper 28/e, p138, 171 (26/e p160, 232); Lippincott Biochem 3/e p310; Ganong23/e p320] Overnight fasting causes insulin levels to fall. This decreases the number of glucose transpoers which are insulin dependent. Insulin dependent glucose transpoers are GLUT-4, present in adipocytes, skeletal and cardiac muscles. Rest of the glucose transpoers are not insulin dependent. Harper writes-"Glucose uptake into muscle and adipose tissue is controlled by insulin, which is secreted by the B islet cells of the pancreas in response to an increased concentration of glucose in the poal blood. An early response to insulin in muscle and adipose tissue is the migration of glucose transpoer vesicles to the cell surface, exposing active glucose transpoers (GLUT 4). These insulin-sensitive tissues will only take up glucose from the blood stream to any significant extent in the presence of the hormone. As insulin secretion falls in the starved state, so the transpoers are internalized again, reducing glucose uptake" Glucose Transpoers Glucose enters cells either by facilitated diffusion or by secondary active transpo with No+ (in the intestine and kidneys) Glucose transpoers are a family of membrane proteins that are responsible for facilitated diffusion of glucose across cell membranes. They differ from and have no homology with the sodium-dependent glucose transpoers, SGLT 1 and SGLT 2, responsible for the secondary active transpo of glucose in the intestine and renal tubules. Seven different glucose transpoers, named GLUT 1-7 in order of discovery. have been characterized. Each transpoer appears to have evolved for special tasks.

The treatment options for steroid-resistant nephrotic syndrome are: Calcineurin inhibitors (cyclosporine, Tacrolinzus) IV or oral cyclophosphamide Levamisol Mycophenolate Pulse corticosteroid All above immunosuppressants are used along with corticosteroids (Prednisolone or methylprednisolone). Cyclosporine and cyclophosphamide are most commonly used. Despite these options, there is a lack of consensus on first line appropriate therapy for steroid-resistant nephrotic syndrome. According to Indian Journal of pediatric (vol. 46, Jan 17, 2009) the efficacy of these drugs are (in decreasing order): Tacrolimus + Prednisolone > cyclosporine + Prednisolone > IV cyclophosphamide + Prednisolone > Pulse Corticosteroids (IV dexamethasone + oral cyclophosphamide + Prednisolne) > oral cyclophosphamide + Predniso-lone.

In the absence of VWF, factor VIII has a half-life of 1-2 hours; when carried by intact VWF, factor VIII has a half-life of 8-12 hours. VWF binds to collagen, e.g., when collagen is exposed beneath endothelial cells due to damage occurring to the blood vessel. Endothelium also releases VWF which forms additional links between the platelets' glycoprotein Ib/IX/V and the collagen fibrils

Large dose of insulin injection will cause hypoglycaemia. Hypoglycemia triggers increased secretion of at least four counterregulatory hormones: glucagon, epinephrine, growth hormone, and coisol. Insulin inhibits glucagon secretion, so low blood glucose has an indirect effect on glucagon secretion through removal of inhibition by insulin. Circulating catecholamines stimulate secretion of glucagon b2-adrenergic receptors Even mild hypoglycaemia is sensed by the CNS, which triggers a central sympathetic response. Glucagon and epinephrine increase the hepatic output of glucose by increasing glycogenolysis. The keys to counter-regulation appear to be glucagon>epinephrine Plasma glucose levels at which various effects of hypoglycemia appear :

Ans. is 'c' i.e., EmphysemaPathogenesis of Emphysema The most accepted theory in the pathogenesis of emphysema is protease - antiprotease mechanism which is responsible in the pathogenesis of two common forms of emphysema, i.e. centriacinar and panacinar.o The alveolar wall destruction results from an imbalance between proteases (mainly elastase) and antiproteases in the lung.o Proteases (elastase) cause destruction of alveolar wall, while antiproteases prevent this damage.o acantitrypsin is the major antiprotease (antielastase) secreted by neutrophils during inflammation.Pathogenesis of panacinar emphysemao Panacinar emphysema is associated with congenital deficiency of arantinypsin.o This results in unchecked overactivity of neutrophil elastase that causes destruction of alveolar wall.o As occantitrypsin is deficient throughout the acinus, the acini are uniformly involved from the respiratory bronchiole to the terminal blind alveoli.o Neutrophils are the major cells in the pathogenesis of panacinar emphysemaPathogenesis of centriacinar emphysemao Centriacinar emphysema is associated with smoking.o Nicotine acts as a direct chemoattractant for neutrophils and macrophages.So, in centriacinar emphysema, both neutrophils and macrophages play central role.Smoking enhances activity of neutrophil and macrophage elastase.o Macrophage elastase is not inhibited by a1-antitrypsin and indeed can proteolytically digest this antiprotease.Beside protease - antiprotease mechanism, oxidant - antioxidant imbalance also plays an impoant role in the pathogenesis of smoking related emphysema.o Normally, the lung contains a healthy complement of antioxidants (superoxide dismutase, glutathione).o Tobacco smoke contains abundant reactive oxygen species (free radicals) which deplete these antioxidant mechanisms.o Free radicals cause tissue damage as well as they inactivate occantitrypsin, resulting in functional acantitrypsin deficiency even in patients without enzyme deficiency.Why smoking related emphysema involves centriacinar poion ?The impaction of smoke paicles occurs predominantly at the bifurcation of respiratory bronchioles, resulting in the influx of neutrophils and macrophages, both of which secrete proteases. An increase in protease activity localized in the centriacinar region, together with the smoke induced oxidative damage, causes the centriacinar pattern of emphysema that is seen in smokers.

Lymphocyte-predominant Hodgkin lymphoma, accounting for about 5% of cases, is characterized by the presence of lymphohistiocytic (L&H) variant RS cells that have a delicate multilobed, puffy nucleus resembling popped corn (“popcorn cell”). L&H variants usually are found within large nodules containing mainly small B cells admixed with variable numbers of macrophages. Other reactive cells, such as eosinophils, are scanty or absent, and typical RS cells are rare. Unlike the RS variants in “classical” Hodgkin lymphoma, L&H variants express B cell markers (e.g., CD20) and usually fail to express CD15 and CD30. Most patients present with isolated cervical or axillary lymphadenopathy, and the prognosis typically is excellent.

Example: CGA to CGG causes no change, since both codons specify arginine. Base changes most commonly occur in 3rd position of codon (tRNA wobble).# Missense mutation: Mutations result in one amino acid being replaced by another. Conservative missense mutation: If the new amino acid is similar in chemical structure. Example: - Sickle cell disease (substitution of glutamic acid with valine at position 6 in the b-globin chain).# Nonsense mutation: Mutations result in a premature termination of the growing polypeptide chain Nucleotide substitution resulting in early stop codon (UAC, UAA, UCA).

Ans. B: ActinomycetesMycetoma is a chronic localized granulomatous inflammatory lesion common in the tropics and sub-tropics.Multiple siAuses, soft tissue swelling and discharge of coloured granules characterize a mycetoma foot. Chronic sinuses discharging granules are caused by (1) Eumycetes (true fungi), (2) Schizomycetes, which includesActinomycosis (aerobic higher filamentous bacteria) andBotryomycosis (bacterial infection).- Actinomycosis is often caused by Actinomadura or Nocardia species wherein it gains entry after penetrating trauma (splinter, gravel or thorn prick).Young males are commonly affected and 75% of the lesions occur in the lower limbs.The disease slowly progresses from a nodule to multiple sinuses discharging coloured granules. Involvement of bone is late following dermal and soft tissue spread.- Botryomycosis (a misnomer), a chronic suppurative infection is caused by bacteria involving skin or viscera . This rare condition mimics a deep mycotic infection and is often caused by Staphylococcus or Pseudomonas species of bacteria. The feet and hands are commonly affected and penetrating trauma may be a predisposing factor. It usually presents as a nodule, sinus or ulcer, which is initially localized.The diagnosis of actinomycosis is based on clinical findings, demonstration of characteristic granules and culture of the organism from a deep tissue biopsy.Immunological studies (counter immuno electrophoresis and ELISA) are also used. Botryomycosis is diagnosed based on a positive gram's stain and culture; negative fungal cultures and demonstration of the characteristic botryomycotic granules at histopathology from a deep biopsy.In endemic areas, subcutaneous swelling with sinuses should be considered as mycetoma unless proved otherwise. The differential diagnosis includes chronic osteomyelitis, tuberculosis and chronic abscesses.

Microglia are a type of neuroglia (glial cell) located throughout the brain and spinal cord. Microglia account for 10-15% of all cells found within the brain. As the resident macrophage cells, they act as the first and main form of active immune defense in the central nervous system (CNS). Microglia (and other neuroglia including astrocytes) are distributed in large non-overlapping regions throughout the CNS. Microglia are key cells in overall brain maintenance--they are constantly scavenging the CNS for plaques, damaged or unnecessary neurons and synapses, and infectious agents. Since these processes must be efficient to prevent potentially fatal damage, microglia are extremely sensitive to even small pathological changes in the CNS. This sensitivity is achieved in pa by the presence of unique K+ channels that respond to even small changes in extracellular potassium. Ref - Wikipedia.org

Ans. is 'a' i.e., Toxoplasmosis Sabin-Feldman dye test A Sabin-Feldman dye test is a serologic test to diagnose for toxoplasmosis. The test is based on the presence of ceain antibodies that prevent methylene blue dye from entering the cytoplasm of Toxoplasma organisms. Patient serum is treated with Toxoplasma trophozoites and complements as activator, and then incubated. After incubation, methylene blue is added. If anti-Toxo antibodies are present in the serum, because these antibodies are activated by complements and lyse the parasite membrane, Toxoplasma trophozoites are not stained (positive result); if there are no antibodies, trophozoites with intact membrane are stained and appear blue under microscope (negative result).

Ans. is 'c' i.e., Specific antibody Hybridomas are cells that have been engineered to produce a specific antibody in huge numbers. Hybridomas Hybridomas are cells that have been engineered to produce a specific antibody in huge numbers To achieve this, qualities of two types of cells have to be combined together i.e. Cells which can produce large amount of pure antibody and Cells which have the ability to grow continually. These two types of cells are then fused together to form hybridoma. Procedure The pure antibody secreting cells are produced by injecting specific antigen in a mouse and obtaining the antigen specific plasma cells (antibody producing cell) from the mouse's spleen. Cell which can grow indefinitely in culture are myeloma cells (cancerous cells). These two cell lines are fused together. The hybrid cell which is thus produced can be cloned to produce large number of identical daughter clones. These daughter clone cells then produce antibodies. Since these antibodies come from only one type of cell (hybridoma cell) they are called monoclonal antibodies. HAT (hypoxanthine, Aminopterin and thymidine) medium is used for preparation of monoclonal antibodies because it allows only fused hybridoma cells to grow. It does not allow the unfused myeloma and unfused antibody cells to grow. So HAT medium is a selective medium which allows (which allow selective growth of fused hybridoma) How does this happen ? Before we move on with the discussion, remember these few points about purine synthesis. Purine synthesis is essential for the survival of cells. Purine can be synthesized in two way i.e. De novo synthesis (dihydrofolate reductase enzyme is required for this pathway). Salvage pathway (an enzyme hypoxanthine - guanine phosphoribosyl transferase is required for salvage pathways) Myeloma cells lack HGPase enzyme therefore they cannot synthesize purine by salvage pathways. o Antibody cells have HGPase enzyme so they can use the salvage pathways. Aminopterin inhibits dihydrofolate reductase an enzyme used in denovo synthesis of purine When two cell lines i.e. antibody producing cell and myeloma cells are grown in HAT medium only the fused hybridoma cells survive. Myeloma cells die because they lack the enzyme HGPase so they cannot use the salvage pathways for purine synthesis. They also cannot use de-novo pathway, because Aminopterin present in the HAT medium inhibits dihydrofolate reductase (an enzyme essential for denovo synthesis ofpurine). The unfused antibody producing cells die as they cannot grow indefinitely because of their limited life span. Only fused hybridoma cells grow indefinitely because the antibody cell paner supplies HGPase and the myeloma paner gives it immoality. (as it is a cancer cell)

While in real life, other diseases (or combinations of diseases) may occasionally cause concurrent pulmonary, sinus, and renal involvement, if you see this pattern on a test question, you should immediately think of Wegener's granulomatosis. This is a rare focal necrotizing vasculitis of still unclear etiology, which also features prominent granulomas, some of which are centered on the vascular lesions. The vasculitis and granulomatous can involve the entire respiratory tract, and an easily obtained nasal biopsy may sometimes yield the diagnosis. The renal involvement is usually in the form of a necrotizing glomerulonephritis. The disease typically affects middle aged men, and its formerly poor prognosis has been improved by coicosteroid and cyclophosphamide therapy. Note: Aspergillosis can cause prominent lung disease, but does not usually have renal involvement. Polyaeritis nodosa is a possibility, but usually spares the lungs. Renal cell carcinoma might cause lung nodules, but there is no evidence of tumor in the kidney.

Pyroptosis is a form of apoptosis that is accompanied by the release of the fever-inducing cytokine IL-1 (pyro refers to fever). Microbial products that enter infected cells are recognized by cytoplasmic innate immune receptors and can activate the multiprotein complex called the inflammasome. The function of the inflammasome is to activate caspase-1 (also known as interleukin-1b-conveing enzyme), which cleaves a precursor form of interleukin-1 (IL-1) and releases its biologically active form. IL-1 is a mediator of many aspects of inflammation, including leukocyte recruitment and fever.

Initial acquisition of mutans streptococci by infants: Evidence for a discrete window of  infectivity. Caufield et al described a discrete “window  of infectivity” during which infants acquired mutans streptococci (MS) from their maternal host.  This “window” opened at 19 months and extended to 31 months, with a mean of 26 months. During this period, the prevalence of MS was seen to rise from 0% to 82%. Caufield hypothesized that the discrete nature of initial MS acquisition was directly related to the presence of nondesquamated hard surfaces, namely newly erupted teeth. Empirically, if the acquisition of these cariogenic bacteria could be blocked during this period, an individual may never acquire these organisms and thereby experience lifelong immunity from dental.

The dose of anticoagulant determined during therapy with these drugs would be higher: if the same is continued after withdrawing the inducer—marked hypoprothrombinemia can occur—fatal bleeding is on record. Metronidazole, fluconazole, and trimethoprim-sulfamethoxazole also stereoselectively inhibit the metabolic transformation of S-warfarin, whereas amiodarone, disulfiram, and cimetidine inhibit metabolism of both enantiomorphs of warfarin. Barbiturates and rifampin cause a marked decrease of the anticoagulant effect by induction of the hepatic enzymes that transform racemic warfarin.
