Multiple endocrine neoplasia type 1 (MEN-1) is characterized by an increased predisposition to the development of tumors of the endocrine tissues, such as parathyroid glands, anterior pituitary, and duodenopancreatic neuroendocrine tumors. It is an autosomal dominant disorder due to germline mutations in the MEN-1 tumor suppressor gene. This gene encodes the menin protein, which is involved in cell growth and differentiation, and in sensing or repairing DNA damage. We present ...

Primary amenorrhea is characterized by the absence of menstruation after the age of 14 without the development of secondary sexual characteristics or after the age of 16 with the development of these. Hypogonadotropic hypogonadism (HH) corresponds to an uncommon etiology of primary amenorrhea.

Introduction: Hypogonadism is common and occurs prematurely in human immunodeficiency virus (HIV)-infected men, being hypogonadotropic hypogonadism (HH) more frequent. However, HH with very low testosterone has not been described. We present three HIV-infected men with severe HH and normal pubertal development.Case report: Three HIV-infected men, with HIV-1 diagnosis at the ages of 22, 34 and 35 years. Two of them had depressive syndrome, one treated wit...

: We report the case of a 57-year-old female diagnosed with Grave’s disease fifteen years before (TSH <0.001 U/ml; FT4 2.3 ng/dl; FT3 7.2 ng/dl, TSAbs 17 U/l). Persistency of hyperthyroidism despite antithyroid therapy led to total thyroidectomy three years after the diagnosis. Thereafter, thyroid function remained normal under hormonal replacement with levothyroxine. The patient had also been diagnosed with Pernicious Anemia at 47 years of age after investigation for...
