Congenital Lipoid Adrenal Hyperplasia, as a Poorly Understood Cause of 46 XY Sexual Differentiation Disorder.

Case: We present the case of a woman who, during the neonatal period, presented salt-losing adrenal insufficiency associated with 46 XY gonadal dysgenesis. The genetic study found a steroidogenic acute regulatory protein (StAR) mutation.

Conclusion: Mutations in StAR result in a nonfunctional protein, which clinically translates into congenital adrenal hyperplasia and, in the case of patients with 46 XY karyotype, is accompanied by gonadal dysgenesis characterized by androgen deficiency, without alterations in anti-Müllerian hormone.

Understanding Progestins: From Basics to Clinical Applicability.

Progestin is a term used to describe a synthetic progestogen. The activity and potency of synthetic progestins are mostly evaluated via parameters associated with their endometrial effects, which are related to their interactions with progesterone, estrogen, androgen, glucocorticoid, and mineralocorticoid receptors. The chemical structure of progestins is the key to understanding their interactions with these receptors and predicting the other effects associated with these drugs.

Successful Multimodal Treatment of an IGF2-Producing Solitary Fibrous Tumor With Acromegaloid Changes and Hypoglycemia.

Doege-Potter syndrome with acromegaloid facial changes is extremely rare. Uncooked cornstarch along with glucocorticoids have been used as supportive care in patients with non-islet cell tumor hypoglycemia (NICTH). Preoperative embolization of hepatic solitary fibrous tumors (SFT) with NICTH has yielded unsatisfactory results.
