Primary Ovarian Insufficiency (POI) affects ~1% of women under forty leading most often to definitive infertility. About 25% of cases seem to be of genetic origin. The recent leap due to whole exome sequencing has led to the identification of new genes involved. Up to now more than sixty genes have been implicated in POI. Diminished Ovarian Reserve (DOR) also leads to female infertility. DOR is defined by a decreased quantity or quality of follicles based on antral follicle co...

Background: FHH is a genetically heterogeneous condition mimicking primary hyperparathyroidism at the difference of low urine calcium excretion. FHH types 1, 2, and 3 are due to loss-of-function mutations of the CASR, GNA11, or AP2S1 genes, respectively. FFH 3, the rarest of the 3, is usually associated to 3 recurrent mutations affecting the arginine residue in position 15. The clinical phenotype has not been well described. We report a new case striking by the neurological in...

Aim of the work: In patients with differentiated thyroid cancer, the basic goal of the therapy is to improve overall and disease-specific survival, reduce the risk of persistent/recurrent disease while minimizing treatment-related morbidity and unnecessary therapy. In 2015, the American Thyroid Association (ATA) published evidence-based guidelines for the staging and management of differentiated thyroid cancer, including the possibility of avoiding systematic complementary 131...

Metformin is a biguanide class agent widely used as a first-line treatment for type 2 diabetes, however the detailed mode of action and exact pharmacodynamics has not been clarified. Moreover there is no studies in humans displaying the effect of metformin on DNA methylation. We therefore performed a clinical study involving twelve healthy nondiabetic individuals who were subjected to the 1 week of metformin (2×850 mg/day) treatment. Peripheral blood for DNA isolation was...

Metabolic Syndrome (MetS) is a cluster of clinical conditions, associated to an increased cardiovascular and metabolic risk, to hypogonadism and erectile dysfunction (ED). Lifestyle modification (including physical exercise, PhyEx) and metformin (MET) are well-known treatments for the condition. We established an animal model of MetS that recapitulates the human phenotype, including andrologic derangements.The aim of this study was to investigate in expe...

The nuclear Farnesoid X receptor (FXR) and the G protein-coupled bile acid receptor 1 (TGR5) are bile acids receptors that play a key role in energy metabolism. In an animal model of non-genomic metabolic syndrome (MetS), obtained with a high fat diet (HFD), treatment with the dual FXR/TGR5 agonist INT767 reduced visceral adipose tissue (VAT) accumulation, insulin resistance, hypercholesterolemia and nonalcoholic steatohepatitis (NASH). In liver, INT767 reduced the high macrop...

Background: The concept of testosterone (T) supplementation (TS) as a new anti-obesity medication in men with testosterone deficiency syndrome (TDS) is emerging.Aim: To systematically review and meta-analyze available observational and register studies reporting data on body composition in studies on TS in TDS.Methods: An extensive Medline Embase and Cochrane search was performed including the following words: ‘testosterone&#1...

Background: The role of testosterone (T) in regulating body composition is conflicting.Aim: To meta-analyze the effects of T supplementation (TS) on body composition and metabolic outcomes.Methods: All randomized controlled trials (RCTs) comparing the effect of TS on different endpoints were considered.Results: Overall, 59 trials were included in the study enrolling 3029 and 2049 patients in TS and control gr...

It has been generally assumed that partner’s erectile dysfunction (ED), premature (PE) and delayed ejaculation (DE) play a significant role in determining Female sexual dysfunction (FSD). The present study aimed to evaluate the role of perceived male partner’s sexual function and of the referred quality of relationship in determining FSD. A consecutive series of 156 heterosexual women consulting our outpatient clinic for FSD between January and December 2014 was retr...

Many conditions may interfere with intestinal absorption of levothyroxine (L-T4). In addition, it has been demonstrated a failure in the normalisation of TSH values in patients consuming L-T4 tablets with coffee or with water followed by coffee taken shortly afterwards. Recent studies showed that oral liquid L-T4 could remove the problem of L-T4 malabsorption by coffee and f...
