Context: Specific references for height, weight and BMI that consider the maturation tempo for onset of puberty are lacking worldwide.Aim: To fill the gap, by developing specific pubertal references for heightSDS, weightSDS and BMISDS, all aligned for the individual onset of puberty.Method: Reference population: a subgroup of GrowUp1990Gothenburg cohort of 1572 (763 girls) health...

Introduction: The National Registry of Civil Status through circular 33 of February 24, 2015 instructed the guidelines for the allocation of a sex through an inscription on the Civil Registry of Birth for intersexual minors.Objective: To create clinical and medical awareness on the importance of making an accurate diagnosis of Congenital Adrenal Hyperplasia CAH in order to avoid adverse effects due the omission of the due diligence by violating of the pr...

Thyroid dysgenesis (TD) is the most common cause of congenital hypothyroidism in iodine sufficient regions. TD includes a broad spectrum of developmental anomalies varying from absence of thyroid (athyreosis) to an abnormally located thyroid (ectopy), small (hypoplasia) or asymmetric thyroid. Thyroid dysgenesis is usually sporadic, but up to 2% of cases is familial. Genetics of TD is complex and advances in developmental biology over the past two decades revealed monogenetic f...

Background: Recently, patients with severe obesity have been described due to functional leptin deficiency. This new entity is characterized by high immunoreactive levels of circulating leptin (Lep), but a reduced bioactivity of the hormone due to defective receptor binding (N Engl J Med 2015;372:48–54). Since these patients can be successfully treated with human recombinant leptin (metreleptin), a diagnostic tool to detect functional leptin deficiency is needed.<p cl...

Background: Prader–willi syndrome (PWS) is characterized by decreased fetal activity, obesity, muscular hypotonia, MR, short stature, hypogonadism and small hands and feet. Little information is available concerning PWS and kidney involvement.Objective and hypotheses: We report two patients with PWS and congenital abnormalities of kidney and urinary tract (CAKUT).Method: First case: male, born at 35 weeks with caesarian sectio...

Background: Patients with PTEN (phosphatase and tensin homolog) hamartoma tumor syndrome and germ line mutations in PTEN frequently develop lipomatosis, for which there is no standard treatment. Rapamycin was shown to reduce the growth of lipoma cells with heterozygous PTEN deficiency in vitro, but concomitantly induced an up regulation of AKT phosphorylation.Objective and hypotheses: Since it was shown that resveratrol stabilizes PTEN,...

Background: 49,XY gonadal dysgenesis (GD) is a very rare disorder of testes development with an incidence of 1:50–100 000. MAP3K1 is a MAPK that mainly regulates the MAPK pathways. High Map3k1 expression was found in female and male mice gonads at 13.5 dpc. In 2010, MAP3K1 mutations were identified in two families with complete and partial XY GD and in two unrelated sporadic cases with complete XY GD (Pearlman 2010 AJMG). Recently, four additional mutations (four out of 4...

Background: Adolescents with gender dysphoria (GD) are treated with gonadotropin-releasing hormone analogues (GnRHa) to prevent the development of characteristics of the undesired sex. Subsequently, sex steroids of the desired sex, cross sex hormones (CSH) are added. GnRHa treatment is generally considered to be safe in the treatment of precocious puberty in children. However, we observed that some adolescents with GD developed hypertension during GnRHa monotherapy (Klink D <e...

Background: Antithyroid drugs (ATD) are recommended as the initial treatment in Graves disease in childhood and adolescence. Identification of predictive factors might lead to improve patient management by facilitating the identification of patients requiring long-term ATD or early alternative therapy.Objective and hypotheses: To assess the prevalence of signs and symptoms of hyperthyroidism in childhood and adolescence, to evaluate the rates of adverse ...

Dyslipidemia is one of the major risk factors for cardiovascular disease in diabetes mellitus. The characteristic features of diabetic dyslipidemia in adults are a high plasma triglyceride concentration, low HDL cholesterol concentration and increased LDL cholesterol. Dyslipidaemia in children with type 1 diabetes mellitus (T1D) have been little studied (P. Lozano et al., 2016; J. D. Schofield et al.,2016; M. Kinoshita et al., 2018; C.Elkins et al., 2019). DECODE studies (Diab...
