Background: Transient neonatal diabetes mellitus (TNDM) is a rare genetic β-cell dysfunction leading to hyperglycaemia that resolves in early childhood. About 80% of patients relapse during adolescence or adulthood. Some of these patients suffer from neurodevelopmental defect. Long-term outcome has been poorly investigated.Objective and Hypotheses: To investigate metabolic and neurologic outcomes in adults affected with TNDM.M...

Background: More than half of newborns with central congenital hypothyroidism (C-CH) have moderate-to-severe hypothyroidism in the neonatal phase, requiring immediate thyroxine therapy to prevent brain damage. The Israeli newborn screening for CH is based on the measurement of total T4 (TT4) followed by TSH measurement. However, when TSH is within the normal range the physicians are not informed of the results and therefore the diagnosis of C-CH and initiation...

Background: In paediatric patients with metabolic bone diseases, measurement of the concentrations of minerals including inorganic phosphate is often indicated, and hypophosphataemia is a clinically manageable biochemical disorder. The clinical interpretation of plasma or serum phosphate concentrations depends, to a certain extent, on the age- and gender-specific reference intervals applicable to the laboratory methods employed.Whereas h...

Background: Genital abnormalities are a source of concern and anxiety to parents and patients and in some cases, for the physicians who may have difficulty making pathological and eventually genetic diagnosis. They range from simple small penis and labial adhesions to the complex genital ambiguity and disorders of sex development.Hypothesis: To determine the genital abnormalities presenting in the Paediatric endocrinology unit of the University of Port H...

Aim: Recommendations for replacement glucocorticoids in CAH suggest a dose per body surface area (BSA) of glucocorticoids of 10-15mg/m2/day to maintain a 17-OH Progesterone (17OHP) level of 12-36 nmol/l across all ages. We used longitudinal analysis to assess whether biomarkers and dose of hydrocortisone varied with age in children within the I-CAH registry .Method: This retrospective multi-centre study, inclu...

Aim: Recommendations for the management of Congenital Adrenal Hyperplasia (CAH) outline a target 17-OH Progesterone (17OHP) of 12-36nmol/l, but do not specify target concentrations for Androstenedione (D4). We aimed to study the temporal variations of these biomarkers in patients from different geographical regions.Method: This retrospective multi-centre study, including 21 centres (14 countries), analysed serum biomarke...

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. ...

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...

Background: Studies on the follow-up of 46,XY partial gonadal dysgenesis (PGD) patients till adulthood are scarce and it is important to provide information to parents on the prognosis of gonadal dysgenesis.Objective and hypotheses: To analyze the long term outcomes of 46XY PGD patients in both social sexes regarding testosterone production, social sex adaption and genotype.Method: Retrospective longitudinal study conducted at Hosp...

Achieving adequate glycaemic control in children with type 1 diabetes (T1D) is essential to reduce incidence and progression of microvascular and macrovascular complications. However, factors that influence glycaemic control remain to be understood. The present study aimed to evaluate clinical, personal, genetic and eating behaviour characteristics underlying glycaemic control in T1D. 325 T1D individuals aged 6 and 20 years and with at least 1 year of disease duration have bee...
