Background: The polyethylene glycol (PEG) method, which utilizes the addition of PEG to precipitate immunoglobulin fractions in order to measure free thyroid stimulating hormone (TSH), has been implemented as a tool for investigating incongruities in TSH measurement.Aim of the study: To investigate the practical application of PEG-TSH testing in pediatric scenarios with a discrepancy between elevated TSH and normal free ...

Background: The QT interval, corrected for sex and heart rate (QTc), measures the duration of the cardiac action potential and can indicate the risk of arrhythmias. The QT interval is typically longer in women compared to men; a phenomenon often attributed to estrogen's effects. However, conflicting data exist regarding the effects of gonadotropin-releasing hormone agonist (GnRHa) and gender-affirming hormonal treatment (GAHT) on QT intervals and dispersi...

Objective: Craniopharyngiomas, diagnosed and treated during childhood, pose significant challenges due to their location in the sella turcica, adjacent to the pituitary and hypothalamus. Patients often experience endocrine deficiencies which may affect their body composition and metabolic health. We aim ed to explore the body composition components and their interaction with metabolic syndrome components in pediatric patients with craniopharyngioma following n...

Background: We previously reported on the strong predictive value of the muscle-to-fat ratio (MFR) z-score in the development of early-onset metabolic syndrome components in children with overweight/obesity. Data on the role of the balance between muscle and fat in the development of childhood onset nonalcoholic fatty liver disease (NAFLD) are sparse. In the current study we explored the interplay between MFR and surrogate markers of NAFLD in children with ove...
