Ans. D: Decreased AFP level Alpha-fetoprotein is made in the pa of the womb called the yolk sac and in the fetal liver, and some amount of AFP gets into the mother's blood. In neural tube defects, the skin of the fetus is not intact and so larger amounts of AFP is measured in the mother's blood. In Down syndrome, the AFP is decreased in the mother's blood, presumably because the yolk sac and fetus are smaller than usual. Estriol is a hormone produced by the placenta, using ingredients made by the fetal liver and adrenal gland. Estriol is decreased in the Down syndrome pregnancy. This test may not be included in all screens, depending on the laboratory. Human chorionic gonadotropin hormone is produced by the placenta, and is used to test for the presence of pregnancy. A specific smaller pa of the hormone, called the beta subunit, is increased in Down syndrome pregnancies. Inhibin A is a protein secreted by the ovary, and is designed to inhibit the production of the hormone FSH by the pituitary gland. The level of inhibin A is increased in the blood of mothers of fetuses with Down syndrome. PAPP-A, which stands for pregnancy-associated plasma protein A, is produced by the covering of the newly feilized egg. In the first trimester, low levels of this protein are seen in Down syndrome pregnancies. It is impoant to keep in mind that even the best combination of ultrasound findings and other variables is only predictive and not diagnostic. For true diagnosis, the chromosomes of the fetus must be examined. Amniocentesis is usually carried out between the 14th and 18th week of pregnancy. CVS is usually carried out between the 10th and 12th weeks of pregnancy.

Ans. is 'c' i.e., 98% of individuals Recommended Dietary allowance (RDA) o Also know as recommended daily allowance. o The RDA is the average daily dietary intake level that is sufficient to meet the nutrient requirments of nearly all (97 to 98%) individuals in a life stage and gender group. o The RDA applies to individuals, not to groups. o The estimated average requirement (EAR) serves as the foundation for setting RDA. If the standard detion (SD) of the EAR is available and the requirement for the nutrient is normally distributed, the RDA is set at 2 SDs above the EAR. RDA EAR 4- 2 SDFAR Adequate intake (AD o The adequate intake is set instead of an RDA if sufficient scientific evidence is not available to calculate an EAR. o The AI is based on observed or experimentally determined estimates of average nutrient intake by a group (or groups) of healthy people. o For example. the "adequate intake" for young infants for whom human milk is the recommended sole source of food for the first 4 to 6 months, is based on the estimated daily mean nutrient intake supplied by human milk for healthy, full term infants who are exclusively breastfed. RIM Vs Adequate intakes (Al) Although RDA and Al are used for the same purpose - setting goals for intake by individuals - The RDA differs from the Al. RDA is expected to meet the needs of 97 to 98% of the individuals, while it is not known what percentage of individuals arc covered by the adequate intake. o The adequate intake does not bear a consistent relationship to the EAR or the RDA because it is set without being able to estimate the average requirement. It is assumed that adequate intake is at or above the RDA if one could be calculated. o The adequate intake for a nutrient is expected to exceed the average requirement for that nutrient, and it should cover the needs for more than 98% of the individuals, but it might cover the needs of far fewer. o The degree to which adequate intake exceeds the average requirements is likely to differ among nutrients and population groups. For people with diseases that increases requirements or who have other special health needs, the RDA and adequate intake may serve as the basis for adjusting individual recommendations, qualified health professionals should adapt the recommended intake to cover the higher or lower needs. Tolerable upper intake level (UL) : - The highest average daily nutrient intake level that is likely to pose no risk of adverse health effects for almost all individuals in the general population. As intake increases above UL, the potential risk of adverse effect increases.

Water in some areas naturally contains fluoride, and dental problems in children are fewer in these areas because tooth enamel is strengthened. Fluoride can be added to drinking water, but opposition to this practice, from ignorance or fear, is common. Copper deficiency can produce neurologic defects. Iodine deficiency can predispose to thyroid goiter. Selenium is a trace mineral that forms a component of glutathione peroxidase; deficiency may be associated with myopathy and heart disease. Serious illnesses from trace element deficiencies are rare. Zinc is a trace mineral that aids in wound healing; a deficiency state can lead to stunted growth in children and a vesicular, erythematous rash.

The patient most likely has a type V hyperlipopro­teinemia, which is associated with eruptive xanthomas secondary to increased triacylglycerol. Type V hyperli­poproteinemia is a combination of type I, characterized by elevated chylomicrons, and type IV, characterized by increased very-low-density lipoproteins (VLDL). Diabetic ketoacidosis and alcoholism are two of the most common factors that promote type V hyperlipo­proteinemia. The absence of insulin characteristic of diabetic ketoacidosis decreases capillary lipoprotein li­pase activity, so neither chylomicrons nor VLDL are properly metabolized in the liver. The increased triac­ylglycerol concentration that results from the accumu­lation of chylomicrons and VLDL in the blood pro­duces a turbid specimen. Because chylomicrons have the lowest density, they form a turbid supranate in plasma left at 4°C overnight. The density of VLDL is slightly higher than that of chylomicrons, so it forms a turbid infranate. Presence of a supranate and in­franate, as in this case, indicates type V hyperlipopro­teinemia. A supranate without an infranate occurs in type I hyperlipoproteinemia, and an infranate without a supranate occurs in type IV hyperlipoproteinemia. Another feature of type V disease is hyperchylomicro­nemia. Clinical features include eruptive xanthomas caused by the deposition of triacylglycerol in the sub­cutaneous tissue. Once the triacylglycerol concentra­tion is reduced, the xanthomas disappear.

The primary features of borderline personality disorder (BPD) are unstable interpersonal relationships, affective distress, marked impulsivity, and unstable self-image. Individuals with BPD tend to experience frequent, strong and long-lasting states of aversive tension, often triggered by perceived rejection, being alone or perceived failure. They may show changeability between anger and anxiety or between depression and anxietyand temperamental sensitivity to emotional stimuli. The negative emotional states specific to BPD fall into four categories: destructive or self-destructive feelings; extreme feelings in general; feelings of fragmentation or lack of identity; and feelings of victimization.

Pathophysiology Airway hyper-reactivity (AHR) - the tendency for airways to narrow excessively in response to triggers that have little or no effect in normal individuals is integral to the diagnosis of asthma and appears to be related, although not exclusively, to airwayinflammation . Other factors likely to be impoant in the behaviour of airway smooth muscle include the degree of airway narrowing and neurogenic mechanisms. The relationship between atopy (the propensity to produce IgE) and asthma is well established and in many individuals there is a clear relationship between sensitisation and allergen exposure, as demonstrated by skin-prick reactivity or elevated serum-specific IgE. Common examples of allergens include house dust mites, pets such as cats and dogs, pests such as cockroaches, and fungi. Inhalation of an allergen into the airway is followed by an early and late-phase bronchoconstrictor response . Allergic mechanisms are also implicated in some cases of occupational asthma . In cases of aspirin-sensitive asthma, the ingestion of salicylates results in inhibition of the cyclo-oxygenase enzymes, preferentially shunting the metabolism of arachidonic acid through the lipoxygenase pathway with resultant production of the asthmogenic cysteinyl leukotrienes. In exercise-induced asthma, hyperventilation results in water loss from the pericellular lining fluid of the respiratory mucosa, which, in turn, triggers mediator release. Heat loss from the respiratory mucosa may also be impoant. In persistent asthma, a chronic and complex inflammatory response ensues, characterised by an influx of numerous inflammatory cells, the transformation and paicipation of airway structural cells, and the secretion of an array of cytokines, chemokines and growth factors. Examination of the inflammatory cell profile in induced sputum samples demonstrates that, although asthma is predominantly characterised by airway eosinophilia, neutrophilic inflammation predominates in some patients while in others scant inflammation is observed: so-called 'pauci- granulocytic' asthma.

Ans. is 'c' i.e., Organophosphorus [Ref Parikh 6Th /e p. 10.43; Reddy 33`d% p. 5231Organophosphorus poisoning compounds are irreversible inhibitors of enzyme cholinesterase, an enzyme which hydrolyzes acetylcholine.Thus organophosphates inhibit cholinesterase and protect acetylcholine from hydrolysis. This results in increased concentration of acetylcholine and excessive cholinergic activity.They inhibit cholinesterase by phosphorylating the catalytic site of enzyme. Less than 50% of cholinesterase activity is indicative of poisoning.Clinical features of poisoning are due to excessive cholinergic activity. Local muscarinic manifestations at the site of exposure (skin, eye, GIT) occur immediately and are followed by complex, systemic effects due to muscarinic, nicotinic and central actions

The information provided in the question is too less, but we have to come to a diagnosis based on the provided information. Lets see each option one by one. Paralytic ileus multiple air fluid levels are noted, hence ruled out. Aganglionosis of the colon or Hirshprung's ds. presents in infancy or childhood hence ruled out Duodenal obstruction multiple air-fluid levels are not noted, but the dominant symptom is recurrent, vomiting, which is not mentioned, hence ruled out. Intestinal pseudo-obstruction it's the most likely diagnosis, as air-fluid levels are not seen in it. Harrison writes - "The symptom of chronic pseudo-obstruction are chronic or intermittent constipation, crampy abdominal pain, anorexia and bloating. Abdominal x-rays reveal gaseous distention of the large and small bowel and occasionally of the stomach. Air-fluid levels are unusual and should raise the possibility of mechanical obstruction." Acute pseudoobstruction involves only the colon and presents with features of colonic obstruction (as described before). Air-fluid level is also not a feature of colonic obstruction. About the fluid levels remember the following points up to 3 to 5 fluid levels less than 2.5 cm in length may be normal. multiple air-fluid levels are a feature of mechanical small intestinal obstruction and paralytic liens. They are not seen in colonic obstruction and pseudo-obstruction. They may be seen in colonic obstruction if the ileocecal valve is incompetent.

Ans. is 'b' i.e., Tryptophan metabolism o Serotonin secretion is increased in carcinoid syndrome which causes flushingQ. VasoconstrictionQ, diarrheaQ and bronchospasm (respiratory distress),Metabolism of tryptophano Tryptophan is an essential amino acidQ, containing indol ringQ. Tryptophan is oxidized to produce alanine (which is glucogenic) and acetyl-CoA (which is ketogenic). Therefore, tryptophan is both glucogenic and ketogenic. Tryptophan is precursor for the biosynthess of niacinQ (a vitaminQ), serotonin (a neurotransmitter) and melatoninQ (a hormone).o Tryptophan metabolism occurs by two pathways: (i) kinurenine pathwayQ and (ii) serotonine pathway.1) Kynurenine pathway :- Tryptophan is oxidized to kynurenine, which is then converted to either niacin (nicotinic acid) or acetyl-CoA. In the reaction alanine is also produced. o Deficiency of tryptophan can cause deficiency of niacin (if also deficient in diet). This can leads to Pallegra: dermatitis, diarrhea and dementia.o For every 60 mg of tryptophan, 1 mg. equivalent of niacin can be generatedQ.o In vitamin B6 deficiency the metabolism is shuted to xanthurenic acid. Therefore, xantheurenic acid excretion is increased in urine.2) Serotonin pathway:- Tryptophan is first oxidized to serotonine which is further converted to melatonin.

Answer is C (CLL) Incidental finding of Lymphocytosis (80,000/mcL) in an elderly and asymptomatic patient suggests the diagnosis of CLL. Why is CLL the single best answer of choice here ? 'CLL is a disease of older patients wth 90% of cases occurring after the age of 50 years and median age of presentation is 65 years'. - CMDT The patient in question is aged 80 years and hence falls in the bracket of CLL. 'Typical B cell CLL is often fbund incidentally when a complete blood count is done for another reason'. -Harrison 16th / 648 The patient in question is asymptomatic and the findings represent incidental observation on a full blood count done for an obscure reason. 'The hallmark of CLL is absolute lymphocytosis. White cell count is usually greater than 20,000/mcL may be markedly elevated to several 100,000/mcL. Usually 75-80% of circulating cells are lymphocytes'. - CMDT The patient in question is presenting with a white cell count of 100,000/mcL and 80% of circulating cells are lymphocytes. This finding is consistent with the blood picture of CLL.

Ans. is 'a' ie. Post flap should be longer than the anterior flop Posterior flap should be longer than the anterior flap as the posterior skin has a good blood supply (and anterior skin has poor due to lack of muscle on anterior aspect). A good blood supply helps in easy healing of stump. - Equally sho anterior and posterior flaps are used only when the long post flap technique is not feasible because of previous wounds or extensive tissue ischemia. 'The longer (the stump) the better', is the general rule for amputation at all sites, but below knee amputation is an exception. The amputation level is kept proximal to the lower third of tibia, since the preponderance of tendinous structures in the lower third predispose to poor circulation and an unstable painful lump. The best level below the knee as, for, as prosthetic fitting is concerned is at the distal musculotendinous junction of the gastrocnemius muscle. Some other imp. points about BK amputation The fibula is transected slightly above the tibial level. No essential differences in healing rate is noted in pts. with or without popliteal pulses, but the absence of a femoral pulse is associated with a high failure rate for BK amputation. The nerves are pulled gently down, transected and then allowed to retract, and the vessels are ligated above the level of the end of tibia.

Pepsin is an enzyme that breaks down proteins into smaller peptides (that is, a protease). It is produced in the stomach and is one of the main digestive enzymes in the digestive systems of humans and many other animals, where it helps digest the proteins in food. Pepsin exhibits maximal activity at pH 2.0 and is inactive at pH 6.5 and above, however, pepsin is not fully denatured or irreversibly inactivated. Therefore, pepsin in the solution of up to pH 8.0 can be reactivated upon re-acidification. Lowering pH does not denature many proteins. Unfolding, yes; denaturation, no. Hydrogen bonds play an impoant role in stabilizing pepsin. Lowering pH does not necessarily break the hydrogen bond network. At least one aspayl residue in the catalytic site needs to be protonated for catalytic action, hence the function at low pH. We do not completely understand the stability of aspayl proteases or pepsin

Clinical assessment Haematemesis is red with clots when bleeding is rapid and profuse, or black ('coffee grounds') when less severe. Syncope may occur and is caused by hypotension from intravascular volume depletion. Symptoms of anaemia suggest chronic bleeding. Melaena is the passage of black, tarry stools containing altered blood; it is usually caused by bleeding from the upper gastrointestinal tract, although haemorrhage from the right side of the colon is occasionally responsible. The characteristic colour and smell are the result of the action of digestive enzymes and of bacteria on haemoglobin. Severe acute upper gastrointestinal bleeding can sometimes cause maroon or bright red stool . Ref Davidson edition23rd pg780

It seldom needs to be worn for more than a week or two.> Reduce: Traction may enlarge the disc space, permitting the prolapse to subside. The head of the couch is raised and weights (up to 8 kg) are tied to a harness fitting under the chin and occiput. Traction is applied intermittently for no more than 30 minutes at a time.> Remove: If symptoms are refractory and severe enough, if there is a progressive neurological deficit or if there are signs of an acute myelopathy then surgery is indicated The disc may be removed through an anterior approach; bone grafts are inserted to fuse the affected area and to restore the normal intervertebral height. If only one level is affected, and there is no bony encroachment on the intervertebral foramen, anterior decompression can be expected to give good long-term relief from radicular symptoms.

Ans. is 'c' i.e., Induction of lipogenesis ACTIONS OF INSULIN Insulin affects the metabolism of carbohydrates, lipids and proteins. Effects on carbohydrate metabolism The overall effect of insulin is to decrease blood glucose level. Insulin increases the utilization of glucose and decreases its production by its following actions : - i) Stimulation of oxidation of glucose by glycolysis especially in the liver and skeletal muscle. ii) Stimulation of glycogenesis i.e., insulin ours conversion of glucose into its storage form, glycogen. This action is seen in both liver and muscles. iii) Inhibition of gluconeogenesis. Insulin stimulates the uptake of glucose by myocytes (skeletal muscle, cardiac muscles), adipocytes (adipose tissue) and hepatocytes. Tissues that do not depend on insulin for glucose uptake include brain, erythrocytes (RBC), the epithelial cells of kidney & intestine, Liver, and Cornea & lens of eye. The mechanism through which insulin increases glucose uptake is different in different tissues. In the muscle and adipose tissues, insulin increase facilitated diffusion by increasing glucose transpoer (GLUT4 ) on the cell membrane. In the liver, insulin stimulates glucose entry into hepatocytes indirectly by induction of glucokinase so that the glucose entering the liver cells is promptly conveed to glucose - 6 - phosphate (glucose trapping). This keeps the intracellular glucose concentration low and ours entry of glucose into the liver. Thus, though the liver do not depend on insulin for glucose uptake, insulin stimulates glucose entry into hepatocytes. That means glucose entery can occur in liver without the action of insulin, but this is facilitated by insulin. On the other hand, myocytes (skeletal and cardiac muslces) and adipocytes (adipose tissue) are dependent on insulin for glucose uptake. Increased uptake of glucose in the glucose has following effects :- i) T Glycolysis :- It is due to induction of key enzymes of glycolysis by insulin. These key enzymes are glucokinase, phosphofructokinase and pyruvate kinase. ii) Increased glycogen synthesis (glycogenesis) :- It is due to induction of glycogen synthase. iii) Decreased glycogen break-down (Glycogenolysis) : - It is due to inhibition of enzyme phosphorylase. iv) Decreased gluconeogenesis :- It is due to inhibition of enzymes Pyruvate carboxylase, PEP carboxykinase, fructose 1, 6-bisphosphatase, glucose - 6 - phosphates. Effects on lipid metabolism Insulin induces lipogenesis by inducing enzyme acetyl CoA carboxylase, the rate limiting enzyme in fatty acid synthesis. Triglyceride synthesis is increased by induction of lipoprotein lipase. Lipolysis (13-oxidation) is decreased due to inhibition of hormone sensitive lipase, so that the fat in the adipose tissue is not broken down. Thus free fatty acid and glycerol are decreased. Because of antilipolytic action insulin decreases ketogenesis. There are two impoant lipases : - i) Lipoprotein lipase : - It hydrolysis the triglycerides of chylomicrons and VLDL into free fatty acid and glycerol in the vessels of skeletal muscles, cardiac muscles and adipose tissue. There FFA is taken up by the cells of these tissue and is conveed back into the triglyceride and the FFA is stored as triglyceride. So, lipoprotein lipase is involved in the synthesis of triglyceride. Lipoprotein lipase is stimulated by insulin, therefore insulin stimulates triglyceride synthesis. ii) Hormone sensitive lipase : - It is involved in lipolysis and cause degradation of stored triglyceride of adipose tissue into FFA and glycerol. FFA comes out into the blood raising the FFA levels of blood. Insulin inhibits hormone sensitive lipase therefore decreases FFA levels of blood. Effects on protein metabolism Insulin stimulates synthesis of protein (anabolism) and inhibits protein breakdown (catabolism). Insulin increases the active transpo of many amino acids into the tissue. In addition insulin increases protein synthesis by increasing the rate of synthesis of mRNA.

(a) Source: (Braunwald, 15/e, pp 318, 323, 822, 1061, 1917-1918.) Urticaria, or hives, is a common dermatologic problem characterized by pruritic, edematous papules and plaques that vary in size and come and go, often within hours. Mast cells may be stimulated by heat, cold, pressure, water, or exercise. Immunologic mechanisms can also cause mast cell degranulation. Folliculitis caused by Pseudomonas aeruginosa can cause a rash, often after exposure to hot tubs. The lesions would not be as diffuse, with a line of demarcation depending on the water level. These lesions are pustular and occur 8 to 48 h after soaking. Erythema multiforme produces target-like lesions and oral blisters often secondary to medications. Erythema chronicum migrans usually presents with a large, solitary annular lesion.

* Fatty change is particularly common in the liver but may occur in other non - fatty tissues as well e.g. in the heart, skeletal muscle, kidneys (lipoid nephrosis or minimum change disease) and other organs.* Fatty change, steatosis or fatty metamorphosis is the intracellular accumulation of neutral fat within parenchymal cells.* It includes, now abandoned, terms of fatty degeneration and fatty infiltration because fatty change neither necessarily involves degeneration nor an infiltration. The deposit is in the cytosol and represents and absolute increase in the intracellular lipids.

Most children are able to produce the bilabial sounds (made with the lips) of “b, p, m, w” first, since these are sounds visible on the lips.  They may also produce sounds (linguo-alveolar) such as “d, n, t” early on as well. These sounds are called linguo-alveolar, since they are produced with the tongue behind the teeth against the alveolar ridge in the mouth.

Enzymes may be simple proteins , or complex enzymes, containing a non -protein pa, called the prosthetic group. The prosthetic group is called the co-enzyme.It is heat stable. The protein pa is named as apoenzyme.It is heat labile.The two poions combined together are called the HOLOENZYME. First group of co-enzymes: In the first group , the change occuring in the substrate is counter balanced by the co-enzymes.Therefore,such co-enzymes may be called as co-substrates or secondary substrates. These takes pa in reactions catalyzed by oxido-reductases by donating or accepting hydrogen atoms or electrons. Second group of coenzymes : These coenzymes take pa in reactions transferring groups other than hydrogen. A paicular group or radical is transferred from the substrate to another substrate.
