Evidence-Based Management of Patients with 45,X/46,XY Gonadal Dysgenesis and Male Sex Assignment: from Infancy to Adulthood.

45,X/46,XY gonadal dysgenesis is a disorder of sexual differentiation with a wide clinical presentation, ranging from Turner-like females to individuals with genital ambiguity to azoospermic but otherwise normal-appearing males. Hence, patients can be assigned female or male sex. Female patients are managed according to the Turner Syndrome Guidelines, whereas males are managed on a case-by-case basis.

Ghrelin prevents tumour- and cisplatin-induced muscle wasting: characterization of multiple mechanisms involved.

Background: Cachexia and muscle atrophy are common consequences of cancer and chemotherapy administration. The novel hormone ghrelin has been proposed as a treatment for this condition. Increases in food intake and direct effects on muscle proteolysis and protein synthesis are likely to mediate these effects, but the pathways leading to these events are not well understood.

Early onset obesity and adrenal insufficiency associated with a homozygous POMC mutation.

Isolated hypocortisolism due to ACTH deficiency is a rare condition that can be caused by homozygous or compound heterozygous mutations in the gene encoding proopiomelanocortin (POMC). Loss of function mutations of POMC gene typically results in adrenal insufficiency, obesity and red hair. We describe an 18 month old Hispanic female with congenital adrenal insufficiency, a novel POMC mutation and atypical clinical features.
