Introduction: Phenotype gender is the outcome of a long and coordinated set of fetal events that are controlled by genetic factors, hormonal factors and environmental factor. In the case of the 46XY fetus, SRY gene on chromosome Y determines the gender and cause bipotential gonad change to testes. And other factors such as sertolli cell by secreting anti-Mullerian hormone which leads to regression of the structures rooted in the paramesonephric ducts (tubes, w...

Background: Vitamin D (25OHD) insufficiency is becoming a public health issue. Adequate 25OHD status during pregnancy may influence the health status of the offspring.Objective: To evaluate the levels of 25OHD from gestation to 12 years, assessing seasonality and intake.Material and methods: Data were obtained from 485 pregnant mothers recruited in Asturias between 2004-2007 and th...

The growth hormone (GH)-insulin-like growth factor (IGF-1) system is essential for optimal human growth and energy homeostasis. Deficiency of pregnancy-associated plasma protein-A2 (PAPP-A2), a protease involved in the liberation of free IGF-1, leads to problems in growth and bone density in humans and mice. Patients with PAPP-A2 deficiency also present lower body mass and mild glucose intolerance. The present study aimed to determine the influence of 1 month of high carbohydr...

Medical antiretroviral treatment changed dramatically the course of the infection and life expectancy of people living with HIV (PLWH). However, age-dependent morbidity and mortality remains high, mostly due to non-HIV related conditions. Among others, cardiovascular diseases is nowadays an important cause of morbidity in PLWH. Integrase inhibitors are now part of the standard treatment scheme, because of their efficacy and tolerability. However, recent reports showed an impor...

Background: Hypothalamic hamartoma (HH) is the most common cause of organic central precocious puberty (CPP). Gonadotropin-releasing hormone analogue (GnRHa) is widely used in the treatment of HH combined with CPP, but there is no report on the medium-and long-term efficacy and safety of HH in China.Objective: To investigate the medium-and long-term efficacy and safety of GnRHa in the treatment of children with CPP cause...

Introduction: The Newborn Screening Programme (NBS) enables earlier diagnosis of congenital hypothyroidism (CH). However, cases of central congenital hypothyroidism (CCH) are missed in countries which use thyroid stimulating hormone (TSH) based screening strategy. Understanding the pathogenic aetiology of CCH is particularly important because many patients have additional pituitary hormone deficiencies. New genes have been implicated in CCH, including the rece...

Introduction: Physiological pubertal gynecomastia is common in adolescents aged 13-14 years. Most physiological pubertal gynecomastia regresses spontaneously within 1-2 years. In studies: If it lasts more than 2 years, if prepubertal has started, endocrine evaluation is recommended. Sex differentiation disorders or genital abnormalities such as increased aromatase activity, adrenal/testicular neoplasia, partial androgen insensitivity syndrome and Klinefelter s...

Background: First line treatment for thyrotoxicosis is thionamide (TA) antithyroid drug therapy. The TA used is usually Carbimazole in the UK. TA can be administered in a relatively large 'blocking' dose that prevents endogenous thyroid hormone synthesis, requiring thyroid hormone replacement (block and replace or BR), or in a smaller dose that renders the patient euthyroid (dose titration or DT). The American Thyroid Association (ATA) recommends DT be...

The obesity epidemic continues to be a dramatic problem in the developed world despite attempts to curtail its rise. Reducing energy intake and/or increasing energy expenditure can result in weight loss; however, if one returns to their poor lifestyle habits the previous weight is not only recuperated, but often surpassed.We hypothesized that although a normal body weight may be achieved, the hypothalamic circuits controlling appetite and energy expendit...

Background: Central diabetes insipidus (CDI) in the neonatal age is usually a result of intracranial insult, either congenital or acquired. Familial CDI is usually an autosomal dominant disorder, presenting later in childhood (1-6 y) with polyuria and mostly caused by mutations in the Neurophysin II moiety of the AVP-NPII prohormone gene; these interfere with prohormone processing leading to gradual destruction of AVP secreting cells and result in arginine vas...
