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...

Stiff person syndrome (SPS) is a rare disease characterized by progressive muscle rigidity and spasms, which can lead to functional disability. This condition can be challenging to diagnose if there is no high index of suspicion. Its etiology is unknown, but one of the most likely causes is autoimmune aggression, which is corroborated by that fact that it is associated with other autoimmune diseases in half of the cases described in literature.We will pr...

Introduction: It is known that thyroid disorders can influence menstrual cycle, but subclinical hypothyroidism (SH), as cause of ovulation disorders and luteal deficiency (LD) in particular,is underestimated. Monitoring women’s cycles, according to the Billings Ovulation Method (BOM), can allow a precise timing for hormonal evaluation and diagnose LD. Usually, a basal TSH value of 2.5 mg/ml is considered as cut-off for a good luteal function, but alone cannot identify all...

Introduction: Knowing that only in 5–15% of FNABs the pathological analysis shows malignancy, enhance diagnostic accuracy is needed. The use of the TIRADS score and a revised version proposed by the British Thyroid Association (BTA) intend to determine if a FNAB should be performed or not in the evaluation of nodular goitre.Objective: To determine whether an adequate correlation is present between the risk category assigned to the nodules studied un...

Gastric carcinoids secondary to autoimmune atrophic gastritis (GC type 1) are usually well differentiated neoplasia, with an indolent course and an excellent overall prognosis. However, a subset of these tumors (<5%) may develop advanced disease, with lymph node and/or hepatic metastasis. The pathogenesis of these carcinoids is related to chronic trophic stimuli to enterochromaffin-like (ECL) cells due to chronic hypergastrinemia. Treatments directed to remove the source o...

Kisspeptin is a neuropeptide secreted in anteroventral-periventricular and arcuate hypothalamic nuclei involved pubertal onset and in other functions of adult life. Kisspeptin levels are sex dependent, so they are higher in prepubertal girls and in adult women compared to age-matched male. This sex-related pattern has been reported in adult obesity, but few data are reported in childhood obesity. In order to evaluate correlations between metabolic status and kisspeptin, we stu...

It is known that in type 1 diabetes mellitus (T1DM) continuous subcutaneous insulin infusion (CSII) therapy improves metabolic control and reduces risk of hypoglycaemia in comparison with multiple daily injection (MDI). Metabolic outcomes usually considered are HbA1c, BMI, and inflammatory parameters. However few data are available on pituitary and gonadal hormone responses, which are involved in metabolic processes. In order to study the response of anabolic hormones in patie...

Introduction: HIV infection and combined antiretroviral therapy (cART) have been associated with lipodistrophy and changes in body composition. However, there are few studies on body composition evolution of HIV-infected patients, under cART.Aims: To evaluate the evolution of body composition in HIV-1 infected patients under cART over 5 years.Methods: Retrospective, observational study in a cohort of HIV-infected patients on cART. ...

The full-length retinoblastoma interacting zinc-finger protein (RIZ), codified by ten exons, has tumour suppressive and differentiating properties and is known to be a downstream effector in classical oestrogen target tissue. In many normal and malignant tissues alternative splicing isoforms, RIZ1 and RIZ2, frame-shift mutations and/or exon deletions have been found, but their oncogenic role is still debated. Although the presence of RIZ1 in the testis has been described, in g...
