What is Endocrinology -The child has fused labioscrotal folds, a large phallus, and no palpable gonads. A uterus and tubes with potential ovaries are seen during the ultrasound scan. XX is the karyotype, 46. What should you do next?
The newborn is a virilized woman. The newborn has one of three kinds of CAH if there is no history of maternal androgen intake or virilization. The most prevalent of them, 21-hydroxylase insufficiency, is identified by discovering an increased serum level of 17-OHP. While 17-hydroxypregnenolone and dehydroepiandrosterone (DHEA) are raised in 3-beta-hydroxysteroid dehydrogenase deficit, 11-deoxycortisol is elevated in 11-beta-hydroxylase deficiency. Although the baseline levels are typically diagnostic, an ACTH stimulation test can confirm them. Although plasma renin activity is higher earlier and should be tested as a sign of salt loss, the electrolyte imbalances associated with such diseases typically do not appear until 8 to 14 days after birth. The measurement of a 17-OHP level during newborn screening for CAH is now required in all 50 states of the United States as well as in many other nations around the world.
