    Endo Q ?

    Advertisements



    Noenate born with ambiguous genitalia,clitorus is enlarged,single perineal opening anterior to anus,no masses in labial folds or inguinal canal,most likely cause of ambiguity in this neonate is,

    A:ANDROGEN INSENSITIVITY
    B:21 Hydroxylase deficincy
    C:5 Alpha reductase deficiency
    D:Mixed gonadal dysgenesis
    E:True hermaphroditism

    they did not tell the sex,of course to ruin the question.

    Why did you capitalize A:ANDROGEN INSENSITIVITY ? Is that a hint? I choose A.

    answer is B:21 Hydroxylase deficincy -- CAH-increase secretin of androgens no mass in labial folds rules out androgen insenstivity or 5 alpha reductase inhibitor as the cause..because in these situations undescended testis will present as mass in labial folds.

    I choose B. 21-hydroxylase deficiency. The presentation fits adrenogenital syndrome, which is the result of no mineralocorticoids produced due to a block in the biosynthetic pathways of progesterone to aldosterone, and no glucocoticoids due to a block in pathtway of 17-hydroxyprogesterone to cortisol. As a result, there is overproduction of testosterone, which leads to the enlarged clitoris that looks like penis in females. In males, may not be as noticeable, but symptoms show eventually with the salt-wasting.
    I used to pray and pray for a bike and never got one. Later I learned that God doesn't work that way... so I went out and stole a bike and asked God for forgiveness.
