Background: X-linked hypophosphatemia (XLH) is caused by mutations in PHEX which increases serum Fibroblast Growth Factor 23 (FGF23) concentrations leading to phosphate wasting and osteomalacia. Burosumab is a recombinant fully human IgG1 monoclonal antibody which selectively inhibits the activity of FGF23. In clinical trials burosumab demonstrated significant clinical improvements in radiological rickets severity, growth, and biochemistry among XLH c...

Background: Mutations in the nicotinamide nucleotide transhydrogenase (NNT) gene are a rare cause of primary adrenal insufficiency (PAI), as well as cardiomyopathies and functional impairment of the gonads.Objective: Despite the description of different NNT mutations in homozygosis and compound heterozygosis in PAI patients, it remains to be clarified to which extent the function and expression of the m...

Background and hypothesis: Mitochondrial disorders are multisystemic conditions associated with sensorineural hearing loss, encephalomyopathy, lactic acidosis, and non-autoimmune diabetes. The majority of molecular etiologies involve mutations in the genes encoding the oxidative phosphorylation system's components. Superoxide generation is significantly increased and causes oxidative damage in the affected tissues in these disorders. The establishment of ...

Context: Differences in sex development (DSD) represent a broad spectrum of conditions that can present at different ages to various healthcare professionals with different backgrounds.Design: This is a retrospective, observational cohort that includes all DSD subjects referred to a multi-professional DSD team over a period of 41 years (from 1980 to 2021).Participants: A total of 6...

Background: Vitamin-D-dependent rickets 1A (VDDR-1A) is a extremely rare, autosomic recessive genetic form of rickets caused by a defect in vitamin D 1α-hydroxylase enzyme which leads to low levels of 1,25-(OH) vitamin D.Herein, we report two Moroccan sisters R.E. and N.E. (respectively 3 and 15 months old), born from consanguineous parents, who presented with psychomotor retardation and failure to thrive.<str...

The majority of treated obese children fail the goals set in the medium-long term or do not show themselves up at the short term follow up. These results, which do not improve even with the proliferation of facilities aimed to the treatment of obesity and of its complications, pose serious questions on how to make the best use of scarce resources available by the National health system. We have visited, between 2013 and 2015, 378 seriously obese children (>2 DS from nation...

Introduction: The evolution of Hashimoto Thyroiditis (HT) has been investigated by several studies both in pediatric and adult age. However, there are limited data on the progression of the disease from childhood to adulthood.Objective: Aim of the study was to describe the evolution of thyroid function in children with HT from childhood to young adulthood.Patients and Methods: The diagnosis of HT was defined by the presence of anti...

Introduction: Delayed puberty (DP), affecting over 2% of adolescents, is defined as pubertal onset 2-2.5 SDs later than the general population. The most common underlying aetiology is self-limited DP (SLDP). However, this can be difficult to differentiate from the more severe condition congenital hypogonadotrophic hypogonadism (HH), especially on first presentation of an adolescent patient with DP. This study sought to elucidate phenotypic and genotypic discre...

Case presentation: G. 15 years 8 months; H 180 cm; P 149.6 kg, BMI 46 kg/m2, second born, father obese, healthy mother and two brothers, no familiarity for T1DM/T2DM, no gestational diabetes. Bronchial asthma, since 2-year-old important weight increase. Flue, polyuria, polydipsia, 12 kg loss in 15 days, anorexia since 5 days, vomit. Hospitalized for tachycardia, dyspnea, and asthenia. On arrival: serious dehydration, Kussmaul breathing, neck subcutaneous emphysema, ...

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...
