Introduction: Central diabetes insipidus (CDI) occurs due to deficient secretion of arginine vasopressin (AVP) or antidiuretic hormone (ADH) by the posterior pituitary. It is a rare disease with an estimated prevalence of 1:25000. CDI can be acquired or congenital, secondary to malformation or genetics. Familial CDI (genetic inheritance) is mainly autosomal dominant. More than 80 mutations in the AVP gene have been described. In hereditary CDI, the age of onset is variable. Sy...

Introduction: D-aspartic acid (D-AA) is involved in the regulation of spermatogenesis by influencing hormonal biosynthesis and secretion, resulting in an increased sperm concentration and progressive motility. Coenzyme Q10 (CoQ10) correlates positively with sperm concentration and motility at high concentrations, and it plays an antioxidant role, improving sperm motility and fertilization rate in ICSI cycles. Finally, low concentrations of zinc (Zn) have been found in azoosper...

Objective: To provide a latent class regression model predictive of surgical outcome in patients with non-functioning macroadenomas (NFMA) of the pituitary gland.Patients and methods: Seventy-five patients with surgically treated NFMA of the pituitary gland were analyzed retrospectively. Thirty-two patients were male. Median age at the time of surgery was 58 years (range: 16–84 years). Median follow-up time was 90 months (range: 14–208 months)....

Objective: 8-Prenylnaringenin (8-PN) is a phytoestrogen discovered in hops. GH3 pituitary adenoma cells of the rat show a variety of responses to phytoestrogens in vitro. This in vitro study aims to analyze changes in hormone expression in GH3 cells treated with 8-PN.Methods: GH3 cells were incubated with 0.5–50 μM 8-PN for 4 h. Medium and ethanol served as controls. Changes in expression of growth hormone (GH) and prolactin (...

Cushing’s syndrome (CS) is associated with a considerable risk of complications including thromboembolic events (TE). They occur mostly within the first 2–3 months postoperatively. When present before surgery, CS has high rates of perioperative mortality and morbidity. The benefit of steroidogenesis inhibitors after TE is not fully known. Furthermore, little guidance is available regarding TE assessment/management in CS. We report a case of a 34-year-old male admitte...

False elevation of estradiol(E2) due to immunoassay interference is a rare but important phenomenon reported in the literature. It is most commonly related to cross-reactivity(CR) from drugs sharing structural similarity with E2, namely fulvestrant and exemestane. These laboratory interferences(LI) can lead to unnecessary investigation/inappropriate treatments. Therefore, in such instances, a more selective and sensitive method is required. We present the case of a young femal...

IntroductionExercise induces changes in the inflammatory profile that can comprehend changes during and immediately after exercise with long-term effects. This inflammatory profile could impact the cognitive function and so, the performance.ObjectivesCompare the inflammatory status from long duration and endurance exercises and correlate it with an immune and neuroendocrine genetic profile.<p class="abste...

Introduction: Diabetes mellitus (DM) may cause male infertility acting with pre-testicular, testicular and post-testicular mechanism.Aim: To evaluate the presence of male infertility and the mechanisms of sperm damage in diabetic patients in childbearing age.Patients and methods: Thirty-four patients with DM1, 55 with DM2 and 100 healthy fertile men (controls) were enrolled. Diabetic patients were further divided into three groups ...

Metabolic Syndrome (MetS) has been frequently associated with an overall inflammation status, called “metaflammation”, including atherosclerosis and non-alcholic steatohepatitis (NASH), In this study we aimed to evaluate the relationship between intra-prostatic inflammation and NASH in a cohort of patients affected by BPH. Between January 2012 and January 2016, 132 consecutive patients with BPH-related lower urinary tract symptoms (LUTS) who underwent transurethral r...

Introduction: Treatment of adrenal insufficiency (AI) in the last years has been object of important changes due to the development of a dual-release preparation of hydrocortisone (Plenadren®). Hydrocortisone dual-release therapy contemplates a once-daily tablet that allows more closely mimicking the physiological circadian rhythm cortisol, thus avoiding overexposure.Objective: The aim of the study was to value effects of Plenadren administration on...
