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.

APGAR score

components SHIRT:


Skin color: blue or pink
Heart rate: below 100 or over 100
Irritability (response to stimulation): none, grimace or cry
Respirations: irregular or good
Tone (muscle): some flexion or active

Extraocular muscles: movements



"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

Ureter to ovarian/testicular artery relation



"Water under the bridge":
The ureters (which carry water), are posterior to the ovarian/testicular artery.

Clinically important, since a common surgical error is to cut ureter instead of ovarian artery when removing uterus.

Superior oblique palsy (aipg2011)

Q.Damage to Superior oblique nerve causes diplopia:
A. Horizontal and downward
B. Vertical and downward
C. Horizontal and upward
D. Vertical and upward


ANSWER:
Ans : B
Injury to the trochlear nerve cause weakness of downward eye movement with consequent vertical diplopia (double vision). The affected eye drifts upward relative to the normal eye, due to the unopposed actions of the remaining extraocular muscles.
As would be expected, the diplopia gets worse when the affected eye looks toward the nose – the contribution of the superior oblique muscle to downward gaze is greater in this position. Common activities requiring this type of convergent gaze are reading the newspaper and walking down stairs. Diplopia associated with these activities may be the initial symptom of a fourth nerve palsy.

Increase in ECF k+

Q.When extracellular k+ is increased from 4 meq to 10 meq what will happen?
a. RMP becomes more negative
b. increase in sodium conductance
c. increase in potassium conductance
d. Na-K ATP ase will be stopped



ANSWER:
ans: B
K+ increased in ECF , will decrease RMP , thereby increasing ecitability and thus increases ability of Na+ to move into the cell (increases its conductance)

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.
