Background: Septo-optic dysplasia (SOD) is a rare congenital anomaly, clinically heterogeneous, combining optic nerve and pituitary gland hypoplasia, midline abnormalities of the brain, including absence of the corpus callosum and septum pellucidum. The diagnosis is made when two or more features of the classic triad are present. HESX1, SOX2, SOX3, FGF8, FGFR1, PROKR1, SHH, are implicated in the etiology of SOD.Objective and hypotheses: Description of a ...

Conclusions: Iodine nutrition status in children in both groups was optimal, based on urinary iodine concentration. Furthermore, there was no significant association between iodine intake and autoimmune thyroiditis....

Introduction: The metabolically healthy obese phenotype (MHOF) defines obese patients who have preserved insulin sensitivity and who do not have metabolic complications: lower risk of cardiovascular disease and type 2 diabetes in adulthood. Recent studies indicate that TMI (kg/m3) estimates the percentage of body fat more accurately than the BMI and it has been proposed to substitute the use of the BMI z-score values by those of the TMI. TMI values ...

Background: Hyperinsulinism/hyperammonaemia (HI/HA) syndrome is associated with postprandial hypoglycaemia and mild hyperammonemia. There is increased insulin release following protein ingestion, which is amenable to diaxozide therapy. While developmental delay and normoglycaemic seizures can also occur, hepatomegaly has not been reported. We report a child with HI/HA and hepatomegaly, mild learning difficulty and obesity, who was initially mistaken to have glycogen storage di...

Background: We report clinical and molecular cytogenetic characterization of a 13-year-7-month-old boy with a Sotos-like phenotype and de novo NFIX deletions and review the literature.Result: A whole exome sequencing revealed in the present patient with unique clinical phenotypes a de novo frameshift mutation c.570-573delATCA (p.S191Ifs*19) in NFIX gene in 19p13.2.Discussion: The p...

Background: Obese adults with normal glucose tolerance (NGT) but 1-h post load glucose (1 hPG)≧155 mg/dl have an increased cardiometabolic risk. In children, preliminary data suggest that 1hPG≧132.5 mg/dl might identify those at higher risk of type 2 diabetes.Objective and hypotheses: To assess whether NGT obese youth with 1hPG ≧132.5 mg/dl (High-NGT) have worse insulin sensitivity and secretion compared to obese youth with 1hPG &#60...

Background: Cis-gender females are known to mount stronger immune responses to invading pathogens or vaccines than cis-gender males. However, this is also associated with increased risk of autoimmunity. Little is known about the immunophenotypes of transgender individuals on gender-affirming hormonal treatment, despite growing evidence that hormones influence the immune system. Via the process of class-switch recombination (CSR), B-cell immunoglobulin isotype ...

Background: GH deficiency (GHD) is an endocrine condition, caused by problems arising in the pituitary gland that does not produce sufficient quantities of GH. GHD is treated by replacing GH with one daily injections. Recent studies suggested that GH could be involved in regulation of certain stem cell subset potential and function. However, the exact effects of GH therapy on biology of stem cells in paediatric patients were not studied in detail.Methods...

Background: In the past decades Brazil has experienced a nutritional transition process characterised by a significant reduction in malnutrition and progressive increase in overweight and obesity. Nutritional education and precocious interventions are useful strategies to combat excess weight in childhood and adolescence. According to the World Health Organization (WHO), there were more than 40 million children overweight in the world in 2011. In Brazil, the prevalence of exce...

The WT1 gene has a crucial role in the genesis of the bipotential genital ridge and subsequently in the specification of the Sertoli cells of testis. Mutations involving the WT1 gene are associated with a wide range of phenotypes impacting testis-determination and development including Denys-Drash syndrome, Frasier syndrome and Meacham syndrome. Here, we describe two sibs with DSD carrying a de novo mutation in the WT1 gene. A girl was born with Prader IV intersex genitals. Cy...
