Introduction: Age at pubertal onset is a markedly inherited trait. The most common cause of pubertal delay, self-limited pubertal delay, is defined by the absence of secondary sexual characteristics after 13 years in girls and 14 years in boys, with progression before age 18. This study aimed to detect novel candidate genes for self-limited pubertal delay.Methods: Eighty-one patients with confirmed self-limited delayed p...

Objective: Most children with short stature remain without an etiologic diagnosis after extensive clinical and laboratory evaluation and are classified as idiopathic short stature (ISS). This study aimed to determine the diagnostic yield of a multigene gene analysis in children classified as ISS.Design and Methods: We selected 102 children with ISS and performed the genetic analysis as part of the initial investigation. ...

Background: The C3 epimer of 25-hydroxi-vitamin D3 (Epi25OHD3) is present in the pediatric and adult population and varies according to age. If it measurement is clinically relevant and should be considered to classify Vitamin D status is still unknown.Objective: To measure 25OHD3, 25-hydroxy-Vitamin D2 (25OHD2) and Epi25OHD3 and to compare them with PTH and calcemia.Method: Subjects: Children between 5 and 8 years of age born very...

Background: Very preterm neonates are at risk for metabolic syndrome later in life. Our objective was to compare anthropometric measures and insulin resistance variables between children who were born very preterm (VPT, <32 gestational weeks) and term (T, >37 gestational weeks), and adequate for gestational age (AGA).Methods: In this cross-sectional cohort study we recruited 113 children 5.0 to 8.5 years old from the preterm clinic of our institu...

Background: A portion of 160 kb on Xp21.2 is defined as dosage sensitive sex reversal, including NR0B1, which is considered the most likely candidate gene involved in XY gonadal dysgenesis if overexpressed. The excess of NR0B1 gene product seems to disturb testicular development by down regulating NR5A1, WT1, and SOX9. Xp duplication causes insufficient SRY expression leading to testis development failure. However, NR0B1 si...

Introduction: The majority of children with short stature are classified as ISS by the absence of findings that could elucidate the cause of their growth impairment. Several monogenic defects have already been identified in children with ISS, but the candidate gene approach is not feasible when there are no specific findings to guide a specific genetic test.Objective: To evaluate the diagnostic yield of a targeted gene p...

Introduction: Hyperglycemia is a common event in neonates, frequently associated with specific clinical conditions (sepsis, drugs or intravenous fluids) other than neonatal diabetes. Unusual endocrino-metabolic syndromes must be considered whenever initial studies are inconclusive.Case report: Newborn term female was admitted at the NICU for intrauterine growth restriction with fluxometric changes and low birth weight (1710 g). Gestational history includ...

Background: Childhood pineal and/or suprasellar intracranial germ cell tumours (IGCT) are highly curable (>90%) with neuraxial radiation alone; international (SIOP) trials have aimed to decrease late radiation-induced neuroendocrine morbidity by substituting chemotherapy. However, without longitudinal study, disease and treatment contributions to long term outcomes remain unknown.Objective: To define tumour and treatment factors implicated in neuroen...

Background: Diabetic ketoacidosis (DKA) is the most serious acute complication of type 1 Diabetes mellitus (T1DM). It is important to know the factors associated with the development of DKA and elaborate preventive strategies to reduce their prevalence.Objective and hypotheses: To identify DKA predictive risk factors in the initial presentation of T1DM in children and adolescents.Method: We conducted a retrospective study, by analy...

Background: In 2011, ATA and AACE published Guidelines on pediatric Graves’ disease (GD) treatment. Nevertheless it is still a controversy.Objective and hypotheses: SPEDP conducted the first nationwide questionnaire survey among all the Endocrinologists and Pediatricians in the Portuguese Public Health System Hospitals about pediatric GD treatment in order to know the reality in our country.Method: SPEDP designed and distribut...
