Congenital hypogonadotropic hypogonadism (CHH) is a rare condition characterized by impairment of pubertal development, that can be associated with hypo/anosmia (Kallmann Syndrome, KS) or normosmia (nCHH). A genetic basis can be identified in nearly 50% of cases, with increasingly common detection of oligogenicity. CHH has a strong male predominance (MtoF ratio 5–3:1), although sex ratio for CHH in families with autosomal inheritance has been proven to be close to equal....

Introduction: TSH-secreting pituitary adenomas (TSHomas) are a rare cause of central hyperthyroidism, accounting for less than 1% of all pituitary adenomas, with a prevalence in the general population of 1-2 cases per million.Case Presentation: A 45-year-old female patient presented in 2009 with hypertension and tachycardia: blood tests revealed an inappropriately normal TSH with high fT3/fT4 levels and primary hyperaldosteronism. She declined further in...

CHH is a rare disease with a relevant genetic background, and is characterized by a failure to enter (complete forms) or to complete (partial forms) pubertal development. It requires a treatment to allow the completion of puberty, and in male this goal can be achieved either using testosterone replacement therapy or administering gonadotropins (Gn); the latter allows both testicular development and the endogenous testosterone production. There are few studies evaluating the th...

Background: As of December 2019, the COVID-19 pandemic has spread rapidly, therefore Governments from all over the world promoted a strategy of social confinement through a general lockdown in order to contain it. During the months following its introduction, many studies reported a significant increase in the incidence of idiopathic central precocious puberty (CPP) throughout several countries, especially in girls.Purpose: The aim of our study was to co...

Introduction: Klinefelter syndrome (KS) is generally characterized by late adolescence/young adulthood onset of primary hypergonadotropic hypogonadism. Fourteen cases have been previously reported on apparently unexplained isolated hypogonadotropic hypogonadism (IHH) in KS. Gonadotropins defect was variably associated with anosmia or other pituitary hormones deficiencies, but no cause could be clearly identified to explain the central defect. We describe the clinical and genet...
