Predictors of surgical complications in boys with hypospadias: data from an internationa registry.

Background: Complications are frequently reported after hypospadias repair and there is a need to understand the factors that influence their occurrence.

Methods: Data from boys with hypospadias born between 2000 and 2020 were obtained from the International Disorders of Sex Development (I-DSD) Registry. Logistic regressions, fisher's exact tests and spearman's correlation tests were performed on the data to assess associations between clinical factors and complication rates.

Copeptin: Utility in Paediatric Patients with Hyponatraemia.

Introduction: Copeptin concentrations are a useful component of the diagnostic workup of paediatric patients with polyuria and polydipsia, but the value of measuring copeptin in patients with hyponatraemia is less clear.

Case Reports: We report 5 children with hyponatraemia in the context of different underlying pathologies. Copeptin concentrations were elevated in 4 cases (13.

Height as a Clinical Biomarker of Disease Burden in Adult Mitochondrial Disease.

Context: Abnormal growth and short stature are observed in patients with mitochondrial disease, but it is unclear whether there is a relationship between final adult height and disease severity.

Objective: To determine whether patients with genetically confirmed mitochondrial disease are shorter than their peers and whether stature is related to disease severity.

Design: Analysis of final adult height in relation to disease severity as determined by the Newcastle Mitochondrial Disease Adult Scale (NMDAS).
