Human NR5A1/SF-1 mutations show decreased activity on BDNF (brain-derived neurotrophic factor), an important regulator of energy balance: testing impact of novel SF-1 mutations beyond steroidogenesis.

Context: Human NR5A1/SF-1 mutations cause 46,XY disorder of sex development (DSD) with broad phenotypic variability, and rarely cause adrenal insufficiency although SF-1 is an important transcription factor for many genes involved in steroidogenesis. In addition, the Sf-1 knockout mouse develops obesity with age. Obesity might be mediated through Sf-1 regulating activity of brain-derived neurotrophic factor (BDNF), an important regulator of energy balance in the ventromedial hypothalamus.

Macroorchidism and panhypopituitarism: two different forms of presentation of FSH-secreting pituitary adenomas in adolescence.

Background: FSH-secreting pituitary adenomas are extremely rare in children and are seldom associated with clinical manifestations of high serum gonadotrophin levels. Thus, most patients have a late presentation, usually as macroadenomas.

Case Reports: Two different clinical forms of presentation of FSH-secreting pituitary adenomas are reported: one in a 12-year-old boy with macroorchidism due to a pituitary microadenoma, probably FSH-secreting, and the other in a 15-year-old boy with panhypopituitarism due to an FSH-producing macroadenoma.

Glycogen storage disease type III with hypoketosis.

A rare case of glycogen storage disease type III with unusually absent ketone body production during hypoglycemia is presented. A 10-month-old boy presented with asymptomatic hepatomegaly. GOT/GPT 2555/1160 IU/L, CK 302 IU/L, triglycerides 1223 mg/dL, cholesterol 702 mg/dL and uric acid 7.

[Anthropometric, dietetic and psychological changes after application of the "Niñ@s en movimiento" program in childhood obesity].

Background And Objective: "Niñ@s en movimiento" is an interventional programme (11 weekly sessions of 90 minutes' duration) designed to modify psychological aspects and nutritional and life style habits in obese children aged 6-12 and in their families.

Patients And Method: Eighty-one obese children (46 girls, 35 boys), 6-12 years of age were included. Body mass index (BMI), Mediterranean diet (KIDMED), anxiety (CMAS-R) and depression tests (CDS) were evaluated in at the start and end of the programme.

Glucose intolerance and diabetes are observed in the long-term follow-up of nonpancreatectomized patients with persistent hyperinsulinemic hypoglycemia of infancy due to mutations in the ABCC8 gene.

Objective: To report the long-term follow-up of three nonpancreatectomized patients with persistent hyperinsulinemic hypoglycemia of infancy due to mutations in the ABCC8 gene.

Research Design And Methods: Oral glucose tolerance test (OGTT) and venous 24-h glucose-insulin profile were performed yearly from adolescence.

Results: Patient 1 (now aged 31 years) developed insulin-dependent diabetes at the age of 25 years.

Human growth hormone (GH1) gene polymorphism map in a normal-statured adult population.

Objective: GH1 gene presents a complex map of single nucleotide polymorphisms (SNPs) in the entire promoter, coding and noncoding regions. The aim of the study was to establish the complete map of GH1 gene SNPs in our control normal population and to analyse its association with adult height.

Design, Subjects And Measurements: A systematic GH1 gene analysis was designed in a control population of 307 adults of both sexes with height normally distributed within normal range for the same population: -2 standard deviation scores (SDS) to +2 SDS.
