Sheehan syndrome refers to panhypopituitarism. It classically follows massive postpaum hemorrhage and associated hypotension. Abrupt, severe hypotension leads to pituitary ischemia and necrosis. In its most severe form, these patients develop shock due to pituitary apoplexy. In less severe forms, loss of gonadotrope activity in the pituitary leads to anovulation and subsequent amenorrhea. Damage to the other pituitary cell types may present as failure to lactate, loss of sexual and axillary hair, and manifestation of hypothyroidism and adrenal insufficiency symptoms.

Which one of the following physiological event of cardiac cycle is responsible for QRS complex?
|
The P wave represents the wave of depolarization that spreads from the SA node throughout the atria. The QRS complex represents ventricular depolarization. Ventricular rate can be calculated by determining the time interval between QRS complexes. The isoelectric period (ST segment) following the QRS is the time at which the entire ventricle is depolarized and roughly corresponds to the plateau phase of the ventricular action potential. The T wave represents ventricular repolarization and is longer in duration than depolarization. The Q-T interval represents the time for both ventricular depolarization and repolarization to occur and therefore roughly estimates the duration of an average ventricular action potential.

All are seen in treacher collin syndrome except
|
Ans. is 'd' i.e., Choanal atresia Treacher collins syndrome It is rare condition that presents several craniofacial deformities of different levels. This is a congenital malformation involving the first and second branchial arches. The disorder is characterized by abnormalities of the auricular pinna, hypoplasia of facial bones, antimongoloid slanting palpebral fissures with coloboma of the lower eyelids and cleft palate. Impoant clinical findings are :- Antimongoloid palpebral fissures Malformed malleus and incus (normal stapes) Coloboma of lower lid Conductive deafness Hypoplasia of mandible (micrognathia) and molar bones Cleft palate Malformed pinna and meatal atresia It is the most common benign neoplasm of nasopharynx. It is a highly vascular tumor and blood supply of the tumor most commonly arises from the internal maxillary aery. Juvenile nasopharyngeal angiofibroma (JNA) occurs almost exclusively in males. Female with Juvenile nasopharyngeal angiofibroma (JNA) should undergo genetic testing. Onset is most commonly in the second decades, the range is 7-19 years. The exact cause is unknown. As the tumour is predominantly seen in adolescent males in the second decade of life, it is thought to be testosterone dependent. The most common site is posterior pa of nasal cavity close to the margin of sphenopalatine foramen. The tumor stas adjacent to the sphenopalatine foramen. Large tumors are frequently bilobed or dumbbel shaped, with one poion of tumor filling the nasopharynx and the other poion extending to the pterygopalatine fossa. Clinical features Symptoms depend on spread of tumour to nasal cavity, paranasal sinuses, pterygomaxillary fossa, infratemporal fossa, cheek, orbits (through inferior orbital fissure), cranial cavity (most common site is middle cranial fossa). Nasal obstruction (80-90%) is the most common symptom, especially in the initial stages. This results in denasal speech, hyposmia, broadening of nasal bridge. pontaneous profuse & recurrent epistaxis is the second most common symptom Otalgia, conductive hearing loss, serous otitis media, due to eustachian tube obstruction. Pink or purplish mass obstructing one or both chonae in nasopharynx. Tumour in the orbit causes : proptosis; and frog-face deformity; diplopia and diminshed vision. Tumour in infratemporal fossa can cause trismus and bulge of parotid. II, III, IV, V, VI cranial nerve can be involved. Splaying of nasal bones. Swelling of cheek and fullness of face. Diagnosis and treatment Contrast CT is the investigation of choice. Biopsy should be avoided as it can cause severe bleeding. Surgical excision is the treatment of choice.

Function of guardian of genome p53 is whicvh of the following?
|
D- Reduced cell mutation rate. P53 is an example of a pro-apoptotic gene k/a Guardian of Genome. If DNA is damaged / mutated p53, repairs it. But if defect is beyond repair - Activation of pro-apoptotic machinery - Apoptosis Result: - Reduced cell mutation rate The p53 protein is the central monitor of stress in the cell and can be activated by anoxia, inappropriate signalling by mutated oncoproteins, or DNA damage. p53 controls the expression and activity of proteins involved in cell cycle arrest, DNA repair, cellular senescence, and apoptosis. DNA damage is sensed by complexes containing kinases of the ATM/ATR family; these kinases phosphorylate p53, liberating it from inhibitors such as MDM2. Active p53 then upregulates the expression of proteins such as the cyclin dependent kinase inhibitor p21, thereby causing cell-cycle arrest at the G1-S checkpoint. This pause allows cells to repair DNA damage. If DNA damage cannot be repaired, p53 induces additional events that lead to cellular senescence or apoptosis.

Surest proof of antemoem burn is

In case of burns, if death has occurred from suffocation,aspirated blackish coal paicles are seen in the nose,mouth,larynx,trachea,bronchi,oesophagus and stomach, and blood is cherry red. Presence of carbon paicles especially in the terminal bronchioles and an elevated CO saturation together are absolute proof that the victim was alive when the fire occurred. In the absence of CO in blood and soot in the airways,death may possibly result due to poisoning with carbon dioxide or deficiency of oxygen. Sometimes inhalation of smoke produces vomiting which may be inhaled and found in the smaller bronchi.

A smoker is worried about the side effects of smoking. But he does not stop smoking thinking that he smokes less as compared to others and takes a good diet. This thinking is called as:
|
Ans. a. Self-exemption (Ref: style="font-size: 1.04761904761905em; font-family: Times New Roman, Times, serif">; Kaplan and Sadock 11/e p590)There are many psychological barriers that need to be overcome in order to successfully quit smoking. Self-exempting belief is one of them."Self-exempting beliefs: A large majority of smokers have the belief that 'it will never happen to me'. For example, someone who runs everyday and doesn't drink alcohol may think that they have less chances of developing lung cancer than the next smoker because their lifestyle 'balances out ' the cigarettes. This is not true. Every smoker has the same risk of negative health outcomes associated with smoking as the next smoker.

Number of ATP generated in one TCA cycle-
|
Ans. is 'c' i.e., 10 o In a single TCA cycle 10 molecules of ATP are produced (12 molecules according to older calculations),o One turn of the TCA cycle, starting with acetyl Co A produces 10 ATPs. When the starting molecule is pyruvate, the oxidative decarboxylation of pyruvate, the oxidative decarboxylation of pyruvate yields 2.5 ATPs and therefore, 12.5 ATPs are produced when starting compound is pyruvate. Since, two molecules of pyruvate enter the TCA cycle when glucose is metabolized (glycolysis produces 2 molecules of pyruvate), the number of ATPs is doubled. Therefore, 25 ATP molecules, per glucose molecule, are produced when pyruvate enters the TCA cycle,o Note : Previously calculations were made assuming that NADH produces 3 ATPs and FADH generates 2 ATPs. This will amount a net generation of 30 ATP molecules in TCA per molecule glucose and total 38 molecules from starting. Recent experiments show that these values are overestimates and NADH produces 2.5 ATPs and FADH produces 1.5 ATPs. Therefore, net generation during TCA is 25 ATPs and complete oxidation of glucose through glycolysis plus citric acid cycle yield a net 32 ATPs.o Energy yield (number of ATP generated) per molecule of glucose when it is completely oxidized through glycolysis plus citric acid cycle, under aerobic conditions, is as follows :- Method of ATP formationNo of ATPs gained perglucose (new calculation)No of ATPs As per old calculationPathwayStepEnzymeSourceGlycolysis1Hexokinase- Minus1Minus 1Do3Phosphofructokinase- Minus1Minus IDo5Glyceraldehyde-3-p DHNADHRespiratory chain2.5x2 =53x2=6Do61J-BPG kinaseATPSubstrate level1x2 =21x2=2Do9Pyruvate kinaseATPSubstrate level1x2 =21x2=2Pyruvate to Acetyl CoA-PyruvateDehydrogenaseNADHRespiratory chain2.5 x 2 =53x2=6 TCA cycle3Isocitrate DHNADHRespiratory chain2.5 x 2 =53x2=6Do4Alpha keto glutarate DHNADHRespiratory chain2.5 x 2 =53x2=6Do5Succinate thiokinaseGTPSubstrate level1x2 =21x2=2Do6Succicinate DHFADH2Respiratory chain1.5 x 2 =32x2=4Do8Mai ate DHNADHRespiratory chain2.5 x 2 =53 x 2= 6Net generation in glycolytic pathway 9 minus 2=710 minus 2=8Generation in pyruvate dehydrogenase reaction=5=6Generation In citric acid cycle=20=24Net generation of ATP from one glucose mole=32=38

A 26-year-woman undeakes a prolonged fast for religious reasons. Which of the following metabolites will be most elevated in his blood plasma after 3 days?
|
As he becomes progressively more starved, his liver will synthesize ketone bodies as an additional fuel for muscle, which cannot meet all of its energy needs from fatty acid metabolism. This spares glucose for the brain and red blood cells. Higher than normal quantities of ketone bodies present in the blood or urine constitute ketonemia (hyperketonemia) or ketonuria, respectively. The overall condition is called ketosis. The basic form of ketosis occurs in starvation and involves depletion of available carbohydrate coupled with mobilization of free fatty acids .

Treatment of choice for stab injury caecum ?

Ans. is 'b' i.e., ileo-transverse anastomosis These options mentioned in the question are of the year 1989; no longer seems to be valid. The management of Colonic injuries in latest edition of Schwaz is: Currently 3 methods for managing the colonic injuries are used? a. Primary repair (it includes lateral suture repair or resection of the damaged segment with reconstruction by ileocolostomy or colocolostomy) b. End colostomy c. Primary reapir with diveing ileostomy Various trials have proven that the Primary repair is safe and effective in viually all patients with penetrating wounds. Schwaz writes- "Numerous large retrospective and several prospective studies have now clearly demonstrated that primary repair is safe and effective in viually all patients with penetrating wounds. Colostomy is still appropriate in a few patients, but the current dilemma is how to select which patients should undergo the procedure. Currently, the overall physiologic status of the patient, rather than local factors, directs decision making. Patients with devastating left colon injuries requiring damage control are clearly candidates for temporary colostomy. Ileostomy with colocolostomy, however, is used for most other high-risk patients."

Renal autoregulation:
|
Ans. D. Minimizes the impact of changes in arterial blood pressure on renal Na+ excretionIn the autoregulatory range, vascular resistance falls when arterial blood pressure falls. Changes in vessel caliber primarily occur in vessels upstream to the glomeruli (cortical radial arteries and afferent arterioles). Because autoregulatory range extends from an arterial blood pressure of about 80 to 180 mm Hg, renal blood flow is not maintained when blood pressure is low; in fact, the sympathetic nervous system will be activated and cause intense vasoconstriction in the kidneys. Renal autoregulation does not depend on nerves.

It has a peak incidence in the fifth decade (according to Maheshwari, young adults). About 50% of hemangiomas of bone occur in veebrae and are most commonly situated in lower thoracic and upper lumbar regions. Other common site of involvement (20%) is skull. Small bones of hands and feets may also be affected. Haemangioma of the veebra has a typical radiographic picture in the form of loss of horizontal striations and prominence of veebral striations. There is Polka dot appearance on CT. In the skull, hemangioma generally affects the calverium and is seen as an expansile lytic lesion which has a sunburst appearance with striation radiating from the centre. A hemangioma may be identified due to associated phlebolith and it may cause local gigantism of the invovled area. Hemangiomas are largely asymptomatic, and thus most are never discovered, leading some to describe these lesions as rare. Treatment is radiotherapy.

Amongst the following extrapyramidal side effect is commonest with which drug?
|
Clozapine is an atypical antipsychotic drug and has negligible risk of extrapyramidal symptoms. Atypical antipsychotic drugs act by antagonistic actions at 5-HT2 and alpha receptors and may or may not possess D2 blocking activity. These drugs are less likely to cause extrapyramidal symptoms. However, most of these agents (except ziprasidone and aripiprazole) can result in weight gain, hyperlipidemia and new-onset diabetes mellitus.

A 22 year old male following a spos trauma presented with pain and stiffness in the neck. On examination, the right shoulder is drooping . Which of the following muscle is likely to be paralysed?
|
Drooping of the shoulder is caused by paralysis of the trapezius. The trapezius is innnervated by spinal accessory nerve (CN XI). It causes retraction of scapula, shrugging of the shoulder and overhead abduction ( along with serratus anterior). Paralysis of trapezius causes drooping of shoulder and slight winging of scapula (the superior angle of scapula becomes more prominent) Ref: Gray&;s Anatomy for students 4th edition Pgno: 101
