Background: Pituitary stalk interruption syndrome (PSIS) is characterized by the absence of the pituitary stalk, pituitary hypoplasia and an ectopic posterior pituitary.Objective: We aimed to retrospectively analyze the clinical, auxological, biochemical, and radiological findings in Spanish patients with PSIS.Patients and results: Of 27 patients, 25% were female and 75% male. Perinatal features, auxological and endocrine study at ...

Background: Intrauterine growth influences the risk of childhood obesity and its associated metabolic derangement.Objective and hypotheses: To investigate the effect of intrauterine growth (as shown by newborn anthropometry) on physical and metabolic features in obese children and adolescents.Method: A retrospective study of 1049 obese children and adolescents (46.8% females/53.2% males; age: 10.31±3.23 years; BMI: +4.00±...

Background: The lipodystrophy syndromes are a heterogeneous group of congenital or acquired disorders characterized by either complete or partial lack of adipose tissue (lipoatrophy). Berardinelli Seip congenital lipodystrophy (BSCL) is a rare metabolic disorder characterized by severe generalised lipodystrophy since birth, insulin resistance, and dyslipemia since early infancy.Case presentation: We report a 6-year-old girl who arrived from Pakistan with...

Background: Despite the lack of drugs, conservative management of childhood obesity allows for considerable weight reduction.Objective and hypotheses: i) To evaluate anthropometric and metabolic changes in obese children after intense weight loss. ii) To analyze the influence of the amount of weight loss and the time spent to attain it on the observed changes. iii) To investigate BMI evolution during the first 3 years after weight reduction.<p class=...

Background: The pituitary set-point for TSH synthesis and secretion is known to be an individual parameter with a strong genetic influence. Type II iodothyronine deiodinase is a pituitary enzyme involved in local deiodination of T4 and negative feed-back loop for TSH secretion. Defects in DIO2 have not been reported in humans; however, Dio2 knockout mouse has pituitary resistance to T4 with elevated TSH, T4 and TSH/T4 ratio, with nor...

Background: Iodotyrosine deiodinase (DEHAL1) is a thyroidal enzyme that deiodinates mono- and diiodtyrosines (MIT, DIT) and recycles iodine, essential for synthesis of thyroid hormone. Iodotyrosine deiodinase deficiency leads to hypothyroidism, goiter and variable mental retardation. The age for clinical onset was reportedly very diverse, allegedly related to individual iodine nutrition.Clinical case: We report on a boy, offspring of consanguineous paren...

Background: The central melanocortin system is highly involved in the control of energy metabolism, receiving and integrating numerous metabolic signals, such as leptin, and biallelic mutations in several genes of the pathway have been reported in severe obesity. However, whether and how heterozygous rare sequence variants (hetRSVs) in genes of this satiety pathway contribute to the development of obesity is poorly explored.Objec...

Background: Obesity is characterised by excessive fat accumulation coursing with a chronic mild inflammatory state, with adipose tissue (AT) being the main site of increased systemic cytokine production. Increased adiposity early in life is the main risk factor for cardiometabolic disorders later in life, with the abnormal accumulation of lipids in AT leading to the production of pro-inflammatory cytokines. Inflammatory process that involves metabolic and card...

Introduction: Carbohydrate restriction (CH-R) in adolescents with obesity results in faster BMI reduction and glucose metabolism improvement than diets with normal carbohydrate proportion, without a higher weight regain in the short term. However, data on weight and metabolic trajectories of these patients after a more prolonged follow-up are sparse.Objectives: To evaluate metabolic and body composition evolution during ...

Background: Mesoderm-specific transcript (MEST) is an epoxide α/β-hydrolase protein with catalytic activity that is determinant for the development of adipocytes. The MEST gene is an imprinted gene transcribed only from the paternal allele. Although the mechanism by which MEST overexpression augments fat accumulation and storage in adipocytes has not been fully elucidated, frequent subcellular contacts between MEST-positive endoplasmic reticulum, mi...
