0 Fordyce

Fox-Fordyce disease is an infrequently occurring chronic pruritic papular eruption that localizes to areas where apocrine glands are found.

Fordyce's spots are small, painless, raised, pale, red or white spots or bumps 1 to 3 mm in diameter that may appear on the shaft of the penis or on the labia, as well as the inner surface (retromolar mucosa) and vermilion border of the lips of the face. They are common in men and women of all ages.The spots are a form of ectopic sebaceous gland: normally, sebaceous glands are only found in association with a hair follicle.

"ObliqLiques cause lateral rotation of eyeball":
Obliques cause lateral, all other rectii are medial rotators of the eyeball.

Action of the obliques is opposite to their names.

Action of the rectii is rightly fitting to their names.

Both superiors cause intorsion and both inferiors cause extorsion

ANSWER:

0 AFP

In normal fetuses, AFP binds the hormone estradiol. AFP is measured , in pregnant women using maternal blood or amniotic fluid, as a screening test for a subset of developmental abnormalities:
It is principally increased in open neural tube defects and omphalocoele & decreased in Down syndrome.

It is also measured in non-pregnant women, other adults, and children, serving as a biomarker to detect a subset of tumors.

In adults, levels over 500 nanograms/milliliter of AFP are seen in only three situations: Hepatocellular carcinoma, Germ cell tumors, and metastatic cancer in the liver originating from other primary tumors elsewhere.
