Introduction: The diagnostic gold standard for Central Precocious puberty (CPP) is the gonadotropin-releasing hormone (GnRH) stimulation test. MR imaging of the brain (MRI) and the hypothalamus-pituitary region is required to exclude organic causes.Objective: The aim of the study was to explore a radiomic model that could assist physicians in the diagnostic workup of CPP.Methods: 4...

Background and aim: Phenotypes of Hypothalamo-Pituitary (H-P) dysfunction are heterogenous and unpredictable. Through novel neuroimaging segmentation, we quantified anatomical alterations of each discrete component (hypothalamus, stalk, and pituitary) to better elucidate the origin and phenotype of different congenital and acquired HP disorders.Methods: We compared 66 patients (35M/31F) aged 12.4 ± 3.1 years, followed...

Background: Hypothalamo-posterior-pituitary (HPP) disorders are complex, life-threatening, and often of uncertain pathogenesis. Oxytocin and AVP/copeptin share production and storage sites, but they are difficult to measure in biological fluids. Correlation with HPP neuroimaging abnormalities has not been previously determined.Aim: To correlate unstimulated plasma copeptin/oxytocin with hypothalamic volumes/PP location i...

Introduction: Langerhans cell histiocytosis (LCH) is a rare disease that the clinical presentation can vary from the involvement of a single region to widespread multiorgan involvement. The most common central nervous system infiltration is observed in the hypothalamic-pituitary region, which frequently leads to central diabetes insipidus (CDİ) and occasionally to anterior pituitary hormone deficiencies. There is limited data on endocrinological findings,...

Introduction: Lack of systematic evaluation for pubertal disorders leads to unnecessary work-up and treatment in physiological cases while missing out pathological cases. Developing a point-of-care tool to allow systematic evaluation of such cases is desirable as it allows early identification and referral.Aim: To develop a web-based tool to guide evaluation in children presenting with pubertal disorders.<p class="ab...

Inherited disorders of biogenic amine metabolism are rare neurometabolic disorders caused by defects in neurotransmitters (dopamine, serotonin, norepinephrine, epinephrine). Dopamine deficiency leads to hyperprolactinemia. Prolactin blood level is used as peripheral indirect biomarker of central dopamine deficiency and can help in adjusting the therapy dosage, which primarily consists of using L-dopa. However, patients may become refractory to L-dopa and they could present hyp...
