Recently it has been shown that somatostatin (SST) might be of therapeutic value in the treatment of active Graves’ophthalmopathy (GO). SST and somatostatin receptors (sst) transcripts are expressed and functional in cultured orbital fibroblasts deriving from GO patients (FGO). Octreotide, the SST analogue currently used is able to inhibit in vitro growth and activity of FGO. New analogues with wider sst-affinity are now available for in vitro experim...

Hypothyroidism therapy is based on the administration of appropriate dose of L-thyroxine (L-T4). Absorption of L-T4 takes place in the duodenum and upper tract of the small intestine (jejunum), is maximal when stomach is empty, and is affected by a number of gastrointestinal disorders, including Helicobacter pylori–related gastritis, as well as ingestion of drugs, dietary fibers, and herbal remedies. Failure to achieve a good control of disease may be due to malabsorption...

IntroductionKallikreins are a subgroup of serine proteases which in women are produced by Skene’s glands. It evaluated the variation of concentrations in KLK3 and immunoglobulins IgA, IgM, IgG and IgE in the menstrual cycle (follicular (FP), ovulatory (OP) and luteal (LF) in young women living in two areas with different environmental impact.Materials and methods82 women aged between 22 and 34, normo-men...

Introduction: The majority of patients with radioiodine-refractory thyroid carcinoma (RAIR-TC) have an indolent disease and require active surveillance (AS) only, while those with progression of the disease (PD) may benefit from local treatment (LT) or systemic therapy with tyrosine-kinase inhibitors (TKI). In the literature, no data about the real impact of LTs in avoiding/delaying systemic treatment in RAIR-TC patients are present.Objective: This study...

Background: Diabetes is an important risk factor for cardiovascular morbidity and mortality but its impact on outcome in acromegaly is unknown.Methods: This was a nationwide, observational, matched-cohort study. Adult patients with acromegaly due to a pituitary adenoma were identified in the Swedish National Patient Registry between 1987 and 2020 and those with coexistent type 2 diabetes in the National Diabetes Registry and Drug Registry. Overall mortal...

Objective: Our institution (University Hospital “L. Vanvitelli“ - Naples, Italy) is a high-volume (HV) center in Naples metropolitan area and many patients are referred there to repeat thyroid fine-needle aspiration cytology (FNAC) after initial FNAC performed in low-volume institutions (LV). The aims of the study were to 1) to examine the inter-observer agreement between HV and LV institutions according to the Italian thyroid cytology system, and 2) explore how the ...

Context: Women with autoimmune Addison’s disease with normally ovulatory cycles but positive for steroid cells antibodies (StCA) have been considered at risk of premature ovarian insufficiency (POI).Design: Thirty-three women younger than 40 years, with subclinical-clinical Addison’s disease but with normally ovulatory menses, were followed-up for 10 years to evaluate the long-term time-related variations of StCA, ovarian function and follicula...

Introduction: Recent studies report the presence of KLK3 in women serum, KLK3 is excreted by Skene glands, it is involved in the production of cervical-vaginal fluid (CVF). Activation of KLK3 is pH depending, it has been hypothesized to have antimicrobial, immuno-regulator activity and vaginal and cervical epithelial desquamation. We intend to verify if KLK3 is present in female serum, in which menstrual cycle phases KLK3 ...

Erythrocytosis is a frequent adverse event associated with testosterone (T) administration in aged hypogonadal men, but the mechanisms involved remain poorly understood. T administration to aged men reduced hepcidin (Hpc) levels, a cytokine regulating iron availability, suggesting a potential role in deregulated erythropoiesis. Aim of present study was to evaluate the effects of T replacement therapy on Hpc levels in young hypogonadal men.Methods: Fifty-...
