The effects of sex hormones remain largely unexplored in pheochromocytomas and paragangliomas (PPGLs) gastroenteropancreatic neuroendocrine tumors (GEP-NETs). We evaluated the estradiol, progesterone, Dehydroepiandrosterone sulfate (DHEAS), testosterone on human patient-derived PPGL/GEP-NET primary culture cell viability (n = 38/n 12), performed next-generation sequencing immunohistochemical hormone receptor analysis PPGL tumor tissues 36). In PPGLs, estradiol progesterone (1 µm)...

Abstract Objective Heterozygous germline loss-of-function variants in AIP are associated with young-onset growth hormone and/or prolactin-secreting pituitary tumours. However, the pathogenic role of c.911G>A; p.(Arg304Gln) (R304Q) variant has been controversial. Recent data from public exome/genome databases show this is not infrequent. The objective work was to reassess pathogenicity R304Q based on clinical, genomic and functional assay data. Design, materials methods Data were...

Gestational diabetes mellitus (GDM) affects nearly 5% of pregnancies. Significant proportion the women with previous GDM develops type 2 (T2DM) in next years, which indicates a higher risk them than general population.We conducted this study to determine factors and incidence abnormal glucose level metabolic syndrome (MetS) history long period after delivery our region.We extracted demographic characteristics 110 who had delivered during 2004 - 2010 three main hospitals Zanjan City, Iran....

The aim of this study was to estimate the incidence hip fracture in Zanjan, Iran and describe its seasonal variation. A total 244 cases fractures (131 men, 113 women) were recorded during 1 year. annual age-standardized rates 206.5 214.8 per 100,000 men women, respectively. Most occurred winter, in-house daytime. In-hospital mortality 2.5%. Incidence rate (HF) less than western countries mostly due lower which is probably because breast-feeding. One most important consequences osteoporosis...

Cushing's syndrome (CS) is a rare disorder, once exogenous causes have been excluded. However, when diagnosed, the majority of cases are adrenocorticotropic hormone (ACTH)-dependent, which substantial minority due to source outside pituitary, ectopic ACTH (EAS). Differentiating among pituitary-dependent CS, disease (CD) and an can be problematic. Because non-invasive tests in evaluation CS patients often lack adequate sensitivity specificity, bilateral inferior petrosal sinus sampling...
