Background: Androgen insensitivity syndrome (AIS) is a genetic disease X-linked, caused by functional abnormalities of the androgen receptor (AR). Mutations in the AR are associated with broad phenotypic spectrum from partial insensibility (PAIS) to complete insensitivity (CAIS).Objective and hypotheses: To characterize the mutations (MUT) identified in the AR in 38 Brazilian families with AIS. The MUT were analyzed considering their type, location in th...

Background: Isolated Growth Hormone Deficiency (IGHD) is usually associated with a delayed bone age. A genetic cause for IGHD is more frequently found in patients with familial cases and/or consanguineous parents.Objective and hypotheses: To diagnose the genetic cause of IGHD and clarify the unusual clinical presentation of advanced bone age in one patient born to consanguineous parents.Method: Sanger sequencing of GH1, <e...

Introduction: The European Registries for Rare Bone and Mineral Conditions (EuRR-Bone) was created in collaboration with the European Reference Network on Rare Bone Diseases (ERN BOND) and the European Reference Network on Rare Endocrine Conditions (Endo-ERN) to support the needs of healthcare providers, patients and researchers by providing high-quality registries. The Core Registry collects a set of Core Data Elements as well as longitudinal patient and clin...

Background: Growth hormone (GH) treatment is indicated for children who are born small for gestational age (SGA) and fail to achieve sufficient catch-up growth during infancy and remain short throughout childhood.Aims: To evaluate the effect of GH treatment in a large, multicentric, Portuguese SGA children cohort and to analyze for correlation between GH treatment response and clinical factors.<str...

Introduction: Small for gestational age (SGA) is a common condition affecting around 10% of all newborns, and it is associated with an increased risk of short stature and other health problems later in life. Growth hormone deficiency (GHD) is a well-known cause of growth failure in children, and it is estimated to affect approximately 1 in 4.000-10.000 children. However, the prevalence of GHD in SGA children with short stature is not well established. Early de...

In a retrospective study (1), we found that a GH<6.5 μg/L, IGF-I-WHO87/518 <30 μg/L and IGFBP-3<0.8 μg/mL confirmed GHD diagnosis with high diagnostic accuracy in neonates with clinical suspicion of GHD. GH and insulin negatively regulate IGFBP-2, and it was proposed to reflect GH status in the diagnostic work-out of GHD in childhood and adults. The accuracy of IGFBP-2 has not been set for neonates.Objective: To prospectively v...

Background: Phthalate exposure results in endocrine disruption by inhibiting steroidogenesis, inducing focal dysgenesis and disrupting germ cell development in the rat fetal testis. Whilst phthalate exposure does not reduce testosterone production by the human fetal testis, its effects on germ cells and induction of dysgenetic areas in the developing human testis are less well described.Objective and Hypotheses: To determine the effects of phthalate expo...

Background: Childhood obesity is a serious public health concern. To identify risk for obesity in early childhood is important.Objective: To analyse association of pre-pregnancy maternal weight with BMI and metabolic profile at 4 years.Methods: 2604 pregnant mothers and 1960 children from the Spanish population-based cohort study Environment and Childhood (INfancia y Medio Ambiente) Project (INMA). Research protocol was approved by...

Introduction: Improvements in the treatment of acute lymphoblastic leukaemia (ALL) and non-Hodgkin lymphoma (NHL) have increased survival, with the consequent concern about the long-term effects that childhood chemotherapy may have on ovarian function. AMH constitutes an indirect, reliable biomarker of the ovarian reserve, useful for the assessment of cancer therapy-related ovarian damage.Aim: To evaluate small ovarian f...

Background: Childhood onset PTC has a more aggressive presentation but no overall increase in mortality compared to adults.Objective: To characterize a pediatric cohort with PTC at diagnosis using the American Thyroid Association (ATA) Initial Risk Stratification (IRS) and to evaluate the response to initial treatment until 3 years based on the modified ATA Dynamic Risk Stratification (DRS) for adults.<p class="abste...
