septo-optic dysplasia/アルギニン

A pituitary evaluation was carried out in a 12-year-old girl who had early puberty, short stature, optic nerve hypoplasia, and agenesis of the corpus callosum. Her growth hormone (GH) response to insulin-induced hypoglycemia and arginine infusion was blunted. Basal and stimulated levels of prolactin

The homeobox gene Hesx1, which encodes a pituitary transcription factor, is first expressed at gastrulation in the mouse embryo. Hesx1 expression begins in prospective forebrain tissue but later becomes restricted to Rathke's pouch, the primordium of the anterior pituitary gland. Transgenic mice

A homozygous substitution of the highly conserved isoleucine at position 26 by threonine (I26T) in the transcriptional repressor HESX1 has been associated with anterior pituitary hypoplasia in a human patient, with no forebrain or eye defects. Two individuals carrying a homozygous substitution of

OBJECTIVE Controversies exist about posterior pituitary (PP) function in subjects with ectopic PP (EPP) and with cerebral midline defects and/or their co-occurrence. We investigate water and electrolyte disturbances in patients at risk for PP dysfunction. METHODS The study was conducted in a single

BACKGROUND Neonatal central diabetes insipidus (CDI) with or without adipsia is a very rare complication of various complex hypothalamic disorders. It is associated with greater morbidity and a high risk of developing both hypernatremia and hyponatremia, due to the condition itself or secondary to

OBJECTIVE Cranial diabetes insipidus (CDI) is rare in infants with no guidelines on its management. We describe the first case series, characterizing the clinical features and treatment challenges. METHODS Retrospective case note review of infants diagnosed with CDI between April 1992 and February
