The leading causes of TBI which may result in pituitary dysfunction are car accidents, falls, sports-related head injuries, violence and war accidents. The prevalence of pituitary dysfunction is approximately 15% following TBI. GH is the most common hormone lost after TBI, followed by gonadotropins (FSH and LH), ACTH and TSH. The proposed pathophysiological mechanisms responsible for the development of pituitary dysfunction after TBI include sella turcica fractures, genetic pr...

Congenital adrenal hyperplasia (CAH) is one of the most common autosomal recessive inherited endocrine diseases and is characterized by complete or partial impairment of adrenal steroidogenesis. 21-hydroxylase deficiency and 11β-hydroxylase deficiency account for 90% and 6–8% of cases of CAH, respectively. NCAH is the mild form of CAH and occurs in approximately 0.1–0.2% in the general population. The worldwide prevalence of NCAH among hyperandrogenic women is a...

Background: Type 1 DM has been shown to be associated with increased rate of hyperandrogenemia, polycystic ovarian changes (PCO) and PCOS. Although stimulated 17-OH progesterone responses to leuprolide has previously been shown to be increased in pubertal girls with type 1 DM, the effect of gonadotropin releasing hormone analog stimulation has not been studied in adult women.Materials and methods: Fifty-two adult women with type 1 DM and 15 healthy adult...

Objective: To investigate the clinical efficacy and safety of the finasteride (5 mg/day) plus flutamide (125 mg/day) combination therapy in unselected women with moderate to severe hirsutism.Patients and methods: Thirty hirsute women were randomly assigned to two treatment groups. Sixteen patients (group 1) were treated with flutamide (125 mg per day) and 14 patients (group 2) were treated with finasteride (5 mg per day) plus flutamide (125 mg per day) f...

The low-dose (1 μg) ACTH stimulation test or glucagon stimulation test (GST) are candidate tests for hypothalamo-pituitary-adrenal (HPA) axis evaluation in patients with pituitary disorders. In this study, we aimed to compare the combination of low-dose ACTH and GSTs (named as combination test) with each test results alone in the evaluation of HPA axis in patients with pituitary disorders whether combination test may overcome the problems when the test results are equivoc...

Objective: To determine the frequency of polycystic ovary syndrome (PCOS) in women with prediabetes compared to control women.Methods: Digital screening and tele-interviews remotely excluded 3218 out of 3465 consecutive women applied for routine check-up. In-person assessments were performed on 247 women, excluding 49. Final analyses included 198 premenopausal women without endocrine disorders (other than prediabetes and PCOS) or conditions affecting gon...

Aim: Traumatic brain injury (TBI) is known to be associated with pituitary insufficiency (PI). We have recently shown that there was a relationship between miR-126-3p, miR-3610 and PI developing in follow up of patients with TBI. In this study, we aimed to test the effects of miR-126-3p on hypothalamus pituitary-adrenal (HPA) and Growth hormone-Insulin like growth factor (GH-IGF-1) axes.Materials and methods: miR126-3p microinjection was performed to mou...

Introduction: Hirsutism affects 5–8% of the whole female population. In most patients, hirsutism is associated with hyperandrogenemia and the most common cause of androgen excess is polycystic ovary syndrome; however, the clinical presentation of non-classical congenital adrenal hyperplasia(NCAH) in females is often indistinguishable from other hyperandrogenic disorders because of common clinical signs with hirsutism and poly cystic ovary syndrome(PCOS).<p class="abst...

Introduction: Patients with Cushing’s Syndrome (CS) frequently have sleep complaints. The aim of the study was to evaluate the prevalance sleep disturbances and sleep structure of patients with CS.Materials and methods: 33 patients with CS were evaluated both clinically and with polysomnograhy (PSG) findings in terms of sleep disorders and data were compared with 20 healthy controls.Results: Seventeen (51.1%) patients with CS ...

Several instances of RNA-mediated inheritance of phenotypic variation have been reported, among them metabolic disorders. We and others have observed that microinjection into naive fertilized mouse eggs of total sperm RNAs of obese and diabetic males maintained on high-fat diet induce the same pathological variation in the offspring. A role of noncoding RNAs is currently the prevailing hypothesis.The sperm RNA content is complex. It depends on environmen...
