We have evaluated the effect of oral administration of arginine chlorhydrate on the growth hormone response to growth hormone releasing hormone in a group of nine short prepubertal children (six boys and four girls). Arginine chlorhydrate 10 g, administered orally 60 min before an i.v. bolus injection of growth hormone releasing hormone 1-29, 1 microgram/kg, significantly enhanced the growth hormone response to the neuropeptide, confirming the results of previous studies which used the i.v. route. Furthermore, our data strengthen the view that the effects of arginine chlorhydrate on growth hormone secretion are mediated by inhibition of endogenous somatostatin release.

Moebius syndrome and hypopituitarism: a case of multiple pituitary hormone deficiency and revision of the literature.

Objectives: Moebius syndrome (MS) is a rare congenital non-progressive rhombencephalic disorder mostly characterised by abducens and facial nerve palsy, but with a multifaceted clinical presentation. Isolated or multiple pituitary hormone deficiencies in the setting of MS have been occasionally reported, but the simultaneous involvement of three or more hypothalamic-pituitary axes has never been described. We hereby report the case of a girl with MS that showed a co-occurrence of GH-, TSH- and ACTH-deficiency.

Objectives: Retinoid X receptors (RXRs) are nuclear hormone receptors (NRs) functioning as transcription factors. There are three RXR isoforms: RXRA (NR2B1), RXRB (NR2B2), and RXRG (NR2B3). RXRs serve as master regulators of gene networks governing cell growth, differentiation, survival, and death.

Background: Recent studies have shown that receptor status of breast cancer change between primary tumor and recurrence, which may influence treatment strategy and prognosis, but there are few reports on receptor discordance between primary tumors and local recurrence (LR) after nipple-sparing mastectomy (NSM).
Patients And Methods: We collected 74 patients who had LR after NSM for newly diagnosed stages 0 to 3 breast cancer between 2008 and 2016 at 14 institutions. We classified into 4 subtypes based on hormone receptor (HR) and human epidermal growth factor receptor 2 (HER2).
Purpose: Uterine leiomyomas (ULMs) are classified into those with and without MED12 mutations (MED12m(+) and MED12m(-), respectively). This study was undertaken to establish a culture system to evaluate the effect of female hormones on the growth of ULM cells in each ULM subtype.
Methods: ULM cells isolated from MED12m(+) or MED12m(-) tissues were cultured in a monolayer for 7 days with four hormone treatments: estrogen (E) and progesterone (P) (E + P), E only (E), P only (P), and medium only (CTRL).
