pt. is suspected to have Ca Prostate as Prostatic Ca is the most common malignant tumor in men over 65 yrs. of age. Symptoms of Bladder outlet obstruction and back pains (due to bony metastasis in the pelvis & lumbar veebra) indicate towards prostate Ca. Serum acid phosphates is a tumor marker of prostate Ca. But now serum acid phosphates assay has been superseded by PSA assay (Prostate specific antigen). Prostate-specific antigen It is a glycoprotein produced only in the prostatic cells (both benign & malignant). It facilitates liquefaction of semen. It is neither sensitive nor specific for early prostate carcinoma (it is prostate specific and not prostate cancer specific), neveheless it gives some help in making a diagnosis. Normal serum level - less than 4 mg/ml 4 - 10 mg/ml - this range is common for both BHP and Ca. More than 10 mg/ml - approx 75% will have cancer. Since PSA is not specific for Ca, PSA Velocity & PSA density is used to detect Prostate cancer. PSA velocity is the rate of change in PSA levels over time and is expressed most commonly as the PSA doubling time. For men with a PSA above 4, PSA velocity of more than .75 mg/ml year is suggestive of Ca. While for those with lower PSA levels, rates above 0.5 mg/ml, per year should be used to advise biopsy. PSA density is calculated by dividing the serum PSA by the estimated prostate weight (measured by TRUS). It was developed to correct for the contribution of BPH to the total PSA level. Values < 0.10 are consistent with BPH. > 0.15 suggest cancer Ref : Bailey & Love 25/e p1356

Ans. d. Codominance (Ref Robbins 9/e p140; Ganong 23/e p527)Inheritance of ABO blood group is Codominance."Although Mendelian traits are usually described as dominant or recessive, in some cases both of the alleles of a gene pair contribute to the phenotype--a condition called codominance. Histocompatibility and blood group antigens are good examples of codominant inheritance. "--Robbins 9/e p140Codominance is a relationship between two versions of a gene, individuals receive one version of a gene, called an allele, from each parent. If the alleles are different, the dominant allele usually will be expressed, while the effect of the other allele, called recessive, is masked. In Codominance, however, neither allele is recessive nor are the phenotypes of both alleles are expressed, e.g., ABO blood group, where in AB blood group both A and B are dominant."Codominance: When both alleles of a gene pair contribute to the phenotype. E.g., Blood group AB.ABO Blood Group SystemA and B antigens of the ABO blood group system are glycoproteins present on the RBC membrane.H substance is the immediate precursor on which A and B antigens are added.H substance is formed by the addition of fucose to the glycolipid or glycoprotein backbone.The subsequent N-acetyl glucosamine creates the A antigen, while the addition of galactose produces the B antigen.Bombay phenotypeIndividuals with the rare Bombay phenotype (hh) do not express the H antigen (also called the H substance), the antigen, which is present in blood group OQ.As a result of the absence of the H antigen they cannot make either the A antigen or the B antigenQ.These individuals have antibodies not only against A and B antigens but also against the H antigenQ.

Perlecan is a large extracellular matrix proteoglycan that plays a crucial role in tissue development and organogenesis. Dystrophin-glycoprotein complex The dystrophin-glycoprotein complex provides a structural link between the cytoskeleton of the muscle cell and the extracellular matrix, which appears to stabilize the sarcolemma, adds strength to the muscle by providing a scaffolding for the fibrils and prevents contraction-induced injury(rupture). Organisation of DG complex Dystrophin connects F-actin to the transmembrane protein b-dystroglycan smaller proteins called syntrophins. This b-dystroglycan, in turn connects to the merosin subunit of laminin 211 in the extracellular matrix a-dystroglycan The dytroglycans are also associated with a complex of four transmembrane glycoproteins, a-,b-,g- and d- sarcoglycan and sarcospan.

The use of a tooth positioner rather than final settling archwires has two advantages:  It allows the fixed appliance to be removed somewhat more quickly than otherwise would have been the case (i.e., some finishing that could have been done with the final archwires can be left to the positioner) It serves not only to reposition the teeth but also to massage the gingiva, which is almost always at least slightly inflamed and swollen after comprehensive orthodontic treatment. The gingival stimulation provided by a positioner is an excellent way to promote a rapid return to normal gingival contours. As a general rule, a tooth positioner in a cooperative patient will produce any changes it is capable of within 2-3 weeks. Final (post-treatment) records and retainer impressions can be taken 2 or 3 weeks after the positioner is placed. Beyond that time, if the positioner is continued, it is serving as a retainer rather than a finishing device-and positioners, as a rule, are not good retainers.

IgA Antibody:- IgA is the second most abundant antibody (2nd highest for DHS). It is of two types: Serum IgA: Predominantly in monomeric form. Secretory IgA (SIgA): It is dimeric (valency four); Secretory IgA is responsible for Mucosal /local immunity. IgA also exist in two subclasses/isotypes: IgA1 is mainly found in serum. IgA2 predominates in secretions. IgA (Secretory IgA) is selectively concentrated in secretions and on mucous surfaces forming an antibody paste and is believed to play, an impoant role in local immunity against respiratory and intestinal pathogens. It protects the mucous membranes against microbial pathogens. It serves an impoant effector function at mucous membrane surfaces, which are the main entry sites for most pathogenic organisms.

The most common neoplasm associated with hypercalcemia is squamous cell carcinoma. Other tumors often associated with paraneoplastic hypercalcemia are carcinomas of the lung, kidney, breast and ovary. Paraneoplastic hypercalcemia is caused by parathyroid hormone-related protein (PTHRP) secreted by these tumours. PTHRP increases bone resorp-tion and renal calcium uptake, while inhibiting renal phosphate transpo, effects that raise serum calcium levels.

In volume cycled ventilation the inspiratory flow rate is usually set at 60-100 U/min to allow greater expiration time for each breath. Use of high inspiratory flow rate can minimize end inspiratory lung volume and intrinsic PEEP, but it can cause higher peak airway pressures. Volume cycled assist control mode of ventilation is the most commonly used mode of ventilation. Volume targeted modes deliver a preset volume unless a specified circuit pressure limit is exceeded. Its major advantages are capacity to deliver unvarying tidal volumes, flexibility of flow and volume adjustments, and power to ventilate difficult patients. Disadvantages of this type of ventilation are: Unless the airway is well sealed volume cycled modes cannot ventilate effectively and consistently. After the flow rate and profile are set the inflation time of machine is set and remains unresponsive to patients native cycling rythm and flow demands.

C i.e. Latent squint Hetrophoria or latent strabismus is a condition in which there is a tendency to misalignment of the visual axis, which is corrected by the fusional capacity. Often latent squints give no trouble until the demand of near vision increase the strain. No symptoms arise, perhaps, until after reading or writing for an hour or two when the letter seems to run together'. There diplopia, which is often not appreciated as actual double vision, causes blurring of the print.

Answer is C (Decrease in serum calcitonin) : Serum calcitonin is no marker fir hyperparathyroidism. It antagonizes the actions of parathyroid hormone and may be used as a modality of treatment of hypercalcemia secondary to hyperparathyroidism. Markers of hyperparathyroidism (|ed PTH): 1. Increased serum calcium: Stimulates Vit D which causes increased absorption of Ca-H- from gut Increased calcium reabsorption from tubules Increases osteoblastic activity in bones and mobilizes calcium from bone into serum. 2. Decreased serum phosphorus: - PTH acts on tubules to increase excretion of phosphorus. 3. Increased 24 hr urine calcium: - Despite increased reabsorption of Ca++ in renal tubules urinary calcium is increased owing to increased filtration of calcium in glomerular filtrate. 4. Increased Alkaline phosphatase: -Increased resorption of bone leads to compensatory elevation of osteoblastic activity 5. Radiological changes: Subperiosteal resorption of phalanges is characteristic (hand X Rays are always advised) Bone resorption i.e. osteitis fibrosa et cystica (brown tumours) `Salt pepper' or 'pepper pot skull' appearance - Loss of lamina dura

Shared psychotic disorder or folie a deux, the characteristic feature is the transmission of delusions from "inducer" (primary patient), who is the "originally" ill patient and suffers from a psychotic disorder to another person who may share the inducer's delusions in entirety or in pa. the person who receives the delusion is usually financially dependent on the inducer person the person who receives the delusion is intellectually less normal and tend to beleive everything that the inducer person tells. both the person who induces and receives the delusion live in close proximity they live in social isolation with less contact with the outside world as they remain together delusion system perpetutes. treament of choice for such patients is seperation of the receiver of delusion from the inducer and the symptom of delusion reduces. Depending on whether the delusions are shared among two, three, four, five and even twelve people, it is called as folie a deux, folie a trios, folie a quatre, folie a cinq and folie a douze.

Ans: a (Lisinopril) Ref: KDT, 6th ed, p. 484* Cough is a side effect of ACE-1.* Bradykinin and substance P seem to be responsible for the cough. Thromboxane antagonism, aspirin, and iron supplementation reduce cough induced by ACE inhibitors. Once ACE inhibitors are stopped, the cough disappears, usually within 4 days.Important points on ACE inhibitorsEnalapril, fosinopril, perindopril, and ramipril are prodrags.Captopril & lisinopril does not require hydrolysis to become active ACE inhibitorEnalapril is converted in the body into enalaprilat. Enalaprilat differs from captopril in that it is an analog of a tripeptide rather than a dipeptide.Adverse effects of ACE inhibitors are cough; hypotension; hyperkalaemia; acute renal failure in patients with bilateral renal artery stenosis, stenosis of the artery to a single remaining kidney, heart failure, or volume depletion owing to diarrhea or diuretics; teratogenicity; skin rash; proteinuria, angioedema and dysguesia.

Behavioral therapy is learning given by BF Skinner , according to him all behaviors are learned phenomenon and thus can be unlearned Positive reinforcement a type of reinforcement when a behavior is rewarded there is more chance that the behavior is repeated Negative reinforcement is that when a behavior is done and an aversive response is removed, the behavior is repeated. When I go and meet my girlfriend, she checks my messages and picks up fight (aversive response) suddenly I delete all messages one day and that day there was no fight (no aversive response) then that behavior is repeated (delete all messages before meeting my girlfriend) Extinction is the type of reinforcement where a behavior is done and a rewarding response is removed the chance is that behavior will not be repeated A child likes to play with children( reward) but when the child fights with other children( undesirable behavior) the child will be removed from playing( removing a reward) , then the child stops fighting with other children( reduction of undesirable behaviour) Ref. kaplon and sadock synopsis, 11 th edition, pg no. 845

Main Action of Secretin: Secretin increases the secretion of bicarbonate by the duct cells of the pancreas and biliary tract. It thus causes the secretion of a watery, alkaline pancreatic juice (with high content of bicarbonate). Its action on pancreatic duct cells is mediated via cAMP. Secretin causes alkaline pancreatic juice to flood into the duodenum, neutralizing the acid from the stomach and thus inhibiting further secretion of the hormone - feedback control. Other actions: Inhibits gastric juice secretion. Inhibits gastric motility. Causes contraction of pyloric sphincter. Augments the potency of action of cholecystokinin on pancreatic secretion.

Ans. is 'a' i.e., Disulfiram o Heroin is diamorphine and is 3 times more potent than morphine.Treatment of morphine or heroin poisoningo Treatment can be divided into:-A. Treatment of toxicity (overdose)# Overdose is a medical emergency, and is treated with opioid antagonist to reverse the complications (respiratory depression) by antagonizing the action on opioid receptors. Intravenous naloxone is the antagonist of choince for morphine (heroin) poisoning. Oral naltrexone is used for maintenance therapy, once acute poisoning has been treated by iv naloxone. Intravenous nalmefene is another specific antagonist.B. Treatment of dependence# Treatment of dependence include medically supervised withdrawal and detoxification, followed by maintenance therapy.a) Detoxificationo Detoxification process include abrupt withdrawal of opioid followed by management of the emergent withdrawal symptoms, i.e., treatment of withdrawal syndrome. Detoxification can be done by any of the following.1. Substitution of long-acting opioid agonism:- Methadone is the treatment of choice. Because of its agonistic activity on opioid receptors it suppresses withdrawal symptoms. L-alpha-acetyl-methadol/ Levomethyl (LAAM) is the other opioid agonist which was used for this purpose. However it is no longer in use because some patients developed prolonged QT intervals (torsades de points).2. Substitution of partial agonist:- Buprenorphine can be used in place of methadone because of its partial agonistic activity on opioid receptor.3. Substitution by a2 agonists:- Clonidine acts as a sympatholytic agent due to its agonistic action on central presynaptic a2 receptors which reduce nor-adrenergic activity. Therefore, clonidine reduces the adrenergic withdrawal symptoms. Lofexidine another a2 agonist, is an alternative to clonidine.4. Clonidine plus naltrexone:- A more rapid detoxification can occur when clonidine is used along with naltrexone. Naltrexone, when given in opioid dependent patient, causes withdrawal symptoms because of its antagonistic action. These can be treated with clonidine. The addition of short acting Benzodiazepine (lorazepam or oxazepam) and NSAIDs, will help relieve withdrawl symptoms not covered by clonidine. It should be kept in mind that naltrexone should not be used alone for detoxification (to treat withdrawl syptoms) as it precipitates or worsens the withdrawl syndrome.5. Other drugs:- Dextropropoxyphene, diphenoxylateb) M aintenance therapyo Once detoxification phase is over (i.e., withdrawal symptoms have been managed), the patient is maintained on any of the following drugs to prevent relapse by reducing craving and preventing 'kick' or 'euphoria' produced by opioids (morphine or heroin). Drugs used are:-1. Methadone:- Reduces craving and 'kick/euphoria' from morphine or heroin because their opioid receptors are already occupied.2. LAAM and buprenorphine:- Similarly reduce craving.3. Opioid antagonists (naltrexone):- Naltrexone can be used orally to assist in the rehabilitation of exopioid abusers who are fully withdrawn (otherwise it induces an acute withdrawl syndrome). Naltrexone prevents relapse by discouraging substance seeking behavior - If a patient, who is on naltrexone maintenance therapy, takes an opioid, there is no 'kick' or 'euphoria' as opioid receptors are already blocked. Naltrexone can be used with clonidine as in detoxification.

Ans. c. Thromboxane A2 (Ref: Goodman Gilman 12/e p868; Katzung 12/e p638; KDT 7/e p195, 6/e p186, 609)Aspirin causes several different effects in the body, mainly the reduction of inflammation, analgesia, the prevention of clotting, and the reduction of fever. Much of this is believed to be due to decreased production of prostaglandins and TXA2."In platelets, the major cyclooxygenase product is TxA2 (thromboxane A 2), a labile inducer of platelet aggregation and a potent vasoconstrictor. Aspirin blocks production of TxA2 by acetylating a serine residue near the active site of platelet cyclooxygenase-1 (COX-1), the enzyme that produces the cyclic endoperoxide precursor of TxA2. Because platelets do not synthesize new proteins, the action of aspirin on platelet COX-1 is permanent, lasting for the life of the platelet (7-10 days). Thus. repeated doses of aspirin produce a cumulative effect on platelet function. "-- Goodman Gilman 12/e p868Drugs affecting Thromboxane A2COX inhibitors like aspirin decreases the synthesis of TXA2QDaltroban & Sultroban are TXA2 receptor antagonistsQDazoxihen inhibits the enzyme thromboxane synthetaseQAspirinAspirin is now rarely used as an anti-inflammatory medication and used for its anti-platelet effectsQ (doses of 81-325 mg once daily).Mechanisms of Action:In platelets, the major cyclooxygenase product is TxA2, a labile inducer of platelet aggregation & a potent vasoconstrictorQ.Aspirin blocks production of TxA2 by acetylating a serine residue near active site of platelet cyclooxygenase-1 (COX-1), enzyme that produces cyclic endoperoxide precursor of TxA2Q.Because platelets do not synthesize new proteins, the action of aspirin on platelet COX-1 is permanent, lasting for the life of the platelet (7-10 days)Q.Clinical UsesAspirin decreases the incidence of transient ischemic attacks, unstable angina, coronary artery thrombosis with myocardial infarction & thrombosis after coronary artery bypass graftingQ.Epidemiologic studies suggest that long-term use of aspirin at low- dosage is associated with a lower Incidence of colon cancer, possibly- related to its COX-Inhibiting effectsQ.Adverse EffectsGastric upset (intolerance) and gastric & duodenal ulcersQ.Hepatotoxicity, asthma, rashes, GI bleeding & renal toxicity rarely if ever occur at antithrombotic doses.Antiplatelet action of aspirin contraindicates its use by patients with hemophiliaQ.

Cutaneous anthrax generally occurs on exposed surfaces of the arms or hands. A pruritic papule develops 1-7 days after entry of the organisms and rapidly changes into a necrotic ulcer. The lesion is called a malignant pustule. The anthrax bacillus is Gram positive and nonacid fast. The spores do not stain by ordinary methods. When blood films containing anthrax bacilli are stained with polychrome methylene blue for a few seconds and are examined under microscope, an amorphous purplish material is noticed around the bacilli. This represents the capsular material and is characteristic of the anthrax bacillus. This is called "McFadyean's reaction" and is employed for the presumptive diagnosis of anthrax.

Ans. is 'b' i.e., Oxidative stress * Normally RBCs are protected from oxidant injury by reduced glutathione. Reduced glutathione is generated from oxidized glutathione and the reducing equivalent for this reaction is provided by NADPH. This NADPH is generated in HMP shunt by enzyme Glucose-6-phosphate dehydrogenase, while oxidizing glucose-6-phosphate.* If G6PD is deficient, NADPH production will be reduced that results in increased susceptibility of RBC to oxidative damage because of unavailability of reduced glutathione. So, whenever there is oxidant stress, e.g. by drugs, infection or foods, hemolysis occurs. G6PD deficiency causes episodic intravascular and extravascular hemolysis.

Because of the ease with which carbon dioxide diffuses across the alveolar membranes, the PaCO2 is a highly reliable indicator of alveolar ventilation. In this postoperative patient with respiratory acidosis and hypoxemia, the hypercarbia is diagnostic of alveolar hypoventilation. Acute hypoxemia can occur with pulmonary embolism, pulmonary edema, and significant atelectasis, but in all those situations the CO2 partial pressures should be normal or reduced as the patient hyperventilates to improve oxygenation. The absorption of gas from the peritoneal cavity may affect transiently the PaCO2 , but should have no effect on oxygenation.
