Background: The diagnosis of 46,XY disorder of sex development (DSD) due to 5-alpha reductase 2 (5α-RD2) deficiency has been based on testosterone:dihydrotestosterone (T:DHT) ratio, urinary steroid profiling and mutational analysis of SRD5A2 gene. The biochemical hallmarks of 5α-RD2 deficiency include increased T:DHT ratio. However, several difficulties are observed in the DHT measurement leading to misdiagnosis. The mutational analysis of the SRD5A2 has been propose...

Background: The TRH receptor (TRHR) is a G-protein coupled receptor activated by hypothalamic TRH. In thyrotropes, TRH-TRHR signalling controls synthesis, secretion and bioactivity of TSH. Human TRHR defects are extremely rare, and only three cases are known with central hypothyroidism and short stature as variable presenting feature.Objective and hypotheses: Phenotypical characterization of a family with suspected central hypothyroidism and inv...

Background: Survivors of childhood brain tumors (SCBT) are an emerging group that have premature mortality and morbidities that can negatively impact their quality of life and lifespan. Cardiovascular disease, obesity and diabetes are important causes of premature mortality in survivors, yet one of the major determinants of cardiometabolic risk i.e. visceral adiposity has not been determined in this group.Objective and hypotheses: This study is comparing...

Background: Perinatal factors seem to influence the onset of puberty. There is some evidence suggesting that being born small for gestational age (SGA) is associated with early puberty, whereas the effect of large size at birth on timing of puberty is not clear.Objective and hypotheses: To evaluate the timing of puberty in children born SGA and large for gestational age (LGA) compared to children born appropriate for gestational age (AGA).<p class="a...

Background: Genetic and epigenetic alterations at the GNAS locus are responsible for the Gsα protein dysfunctions causing Pseudohypoparathyroidism (PHP), a heterogeneous disease characterized by multiple hormone resistances and AHO signs (short stature, obesity, round face, brachydactyly, subcutaneous ossifications and mental retardation). A clinical overlap among molecular subtypes of the disease (Ia, Ib, Ic and II) makes the current classification inadequate; furthermor...

Background: Virilization of young children after topical androgen use by their fathers through skin contact is well-known. The long-term consequences of such exposure at very young age are not well known.Objective and hypotheses: The aim is to report the occurrence of spermarche in a young boy and central precocious puberty in a young girl as late consequences of interpersonal transfer of testosterone gel.Method: Testosterone conta...

Growth hormone deficiency (GHD) is a relatively rare cause for short stature resulting from insufficient secretion of growth hormone (GH). With complicated etiology, GHD can coexist in numerous syndromes or disorders such as Turner Syndrome. So, it is necessary to take genetic analysis to patients with GHD especially those perform various phenotypes. A 9.5 years old boy complained of short stature was diagnosed with GHD by height velocity (HV) <5 cm/year, delayed bone age ...

Introduction: GLIS3 is a member of the GLI-similar zinc finger protein family encoding for a nuclear protein that maps to chromosome 9p24.3-p23. Mutations in GLIS3 have been reported in association with Neonatal diabetes mellitus and hypothyroidism syndrome. We aimed to present a case of congenital diabetes mellitus congenital hypothyroidism associated with a newly identified mutation in the GLIS-3 gene.Case Report: A se...

Introduction: The identification of obese patients with increased susceptibility and risk for glucose intolerance and type 2 diabetes requires an oral glucose tolerance test (OGTT). Reference values for Body mass index (BMI) and Tri-Ponderal mass index (TMI) according to age and sex of healthy children in Spain without malnutrition or obesity have recently been published (*). TMI values remain very uniform in both boys and girls from the age of 8 to 18 years, ...

Background: The Adrenocortical Neoplasm (ACN) is a rare condition in childhood (0,3 cases/1000000). In paediatric age, ACN at stage 1 is treated by complete adrenalectomy, while at stages 2 and 3 surgery is followed by adjuvant treatment with Mitotane (M). Chemotherapy is required in metastatic cases (stage 4).Objective and hypotheses: M is an adrenal cytotoxic agent which has both adrenolytic action on ACN cells and inhibition on steroid hormone synthes...
