its correct..........
now remember chromosomal rearrangement in ret like ret/ptc translocation i sassociated with papillary ca

and here germ line ret with medullary

hyperthy


now here u r partially correct....................

carotenimia seen in hypo not in hyper
4 hepatic conversion of carotien to vit a thyroid hormones r req so in hypo there will be less thyroid harmone and accumulation of carotein in blood that is carotenimia...........

this will impart pale colour to skin .......so pale skin
but it will not show pale bulbar conj and hence it can be clinically distinguish frm jaundice

so ans is hyper and pale conj

barbie i think u answerd hyper..................................

its true...................... in chrioca hyper is seen

reason is tht in chorio ca more hcg is released..................... and there is structural resemblance bet hcg and tsh ...................... so more hcg more will be production of t3 and t4...........................ok

good que barbie

1)Tertiary hyperparathyroidism is a state of excessive secretion of parathyroid hormone after a long period of secondary hyperparathyroidism and resulting in hypercalcemia.

2)Calciphylaxis is a syndrome of vascular calcification, thrombosis and skin necrosis. It is seen almost exclusively in patients with end stage renal disease. It results in chronic non-healing wounds
This is one type of extraskeletal calcification.
Similar extraskeletal calcifications are observed in some patients with hypercalcaemic states, including patients with milk alkali syndrome, sarcoidosis, primary hyperparathyroidism, and hypervitaminosis

now u tell me which drug has side effect-------- milk alkali syndrome ok

3) pheochromo more common in men 2a

4) i think its chro 10 4 medularry ca....................men2a also belongs to same chromosome...........plz confirm it

for aldosterone what is false

a) hypertension seen

b) acidic urine

c) can be seen in cushing disease

d) edema is seen


genodr
Aim AIIMS May 2011

insulin is secreted with response of

a) glut1

b) 2

c) 3

d) 4


robin


In primary hyperaldosteronism, Na accumulation is usually gradual and is dependent on its availability and on the magnitude of aldosterone excess. After a gain of about 1.5 kg of extracellular fluid, however, there is diminished renal Na reabsorption. This phenomenon, which accounts for the absence of edema in this disorder and is referred to as mineralocorticoid escape, enables the kidney to overcome the Na-retaining effects of mineralocorticoid excess and, consequently, maintain Na balance.

here u r partially right ............

see endorphins also sec by corticotroph which is the part of ant lobe

so ans should be middle and ant both...ok

here too u r partially correct.......u r right 4 cushing syndrome

see the concept is tht hyperpigmentation is seen in presence of more

ACTH which is responsible 4 dopa production and ultimatly melanine

and in cushing syndrome exclusively caused by cushing disease there will

be more ACTH production and skin pigmentation..cushing syndrome due

to adrenal cause will show hypopigmentation

because in this more cortisol production will have inhibitory effect on

ACTH and less ACTH

will form....

2) NELSON syndrome is the rapid enlargement of a pituitary adenoma that occurs after the removal of both adrenal glands.due e to loss of inhibitory control of cortisol on pitu............so in this too u will get more ACTH and hence hyperpigmentaion is seen

so ans is nelson and cushing both

now u tell me abt other two syndrome.........empty sella and sheens syndrome
