Introduction: The pubertal transition is accompanied by voice break in boys. Studies asking men to retrospectively recall their age at voice break report an average age of voice break corresponding to 13.4-14.0 years. However, it may be difficult to remember precisely when your voice broke, and recall bias is quite large. Little is known about voice frequency in boys and girls in relation to pubertal timing.Aim: To asses...

Introduction: In the last 10 years, blue light (BL) sources such as tablets and phones has increased in every age group. Especially due to the Covid-19 pandemic, screen exposure has also increased in childhood. However, the effects of BL exposure in the puberty process aren’t clear. We aimed to examine the effect of BL exposure and exposure time on pubertyMethods: Immature eighteen 21-day-old female Sprague Dawley ...

Background: The International Congenital Adrenal Hyperplasia (CAH) Registry provides rich longitudinal data from CAH patients with 21 Hydroxylase deficiency. We estimated the average total causal effect of fludrocortisone on blood pressure in patients with CAH by modelling within a causal inference framework.Methods: We constructed a directed acyclic graph (DAG) with domain experts (using Dagitty.net) to establi...

Relations of Birth Chest Circumference to Blood Serum IGF1 in the Newborn Free of Life-threatening Disease: Possible Role of Birth Body Weight in Addition to Respiratory Supportive Treatment

Terzi Cesare , Blum Werner F , Tridenti Gabriele , Cerioli Andrea , Riani Marco , Chesi Elena , Bernasconi Sergio , De Angelis Gian Luigi , Magnani Cristiana , Virdis Raffaele , Banchini Giacomo

Background/objective and hypotheses: Chest circumference (CC) is related to intrauterine growth rate as well as to development-function of respiratory system. We evaluated the relevance of birth body weight (BW) in birth CC (BC) relations to blood serum IGF1 after control for preterm birth (PTB), oxygen (O2) supplementation as %O2 in respiratory gases (O2R) and assisted ventilation of any kind (AV) in the newborn (NWB) without life-threatening ...

Background/objective and hypotheses: Chest circumference (CC) is related to intrauterine growth rate as well as to development-function of respiratory system. We evaluated the relevance of birth body weight (BW) and blood serum IGF1 (IG1) in birth CC (BC) relations to blood serum IGF-binding-protein-3 (IB3) after control for preterm birth (PTB), oxigen (O2) supplementation as %O2 in respiratory gases (O2R) and assisted ventilation of any kind (...

Pseudohypoaldosteronism Type 1: Role of Urinary Steroid Profiling in Specific and Early Diagnosis: Lessons in Differential Diagnosis of PHA1 vs PHA2 (Renal Tract Anomaly)

Abbot V , Ghataore L , Pieterse D J , Chapman S , Kapoor R R , Taylor N F , Buchanan C R

Background: Pseudohypoaldosteronism type 1 (PHA1) is a rare disorder of neonatal salt loss unresponsive to mineralocorticoids, requiring salt supplementation. It results from resistance of kidney and/or other tissues to mineralocorticoids, arising from mutations in genes encoding mineralocorticoid receptor (MR: NR3C2; autosomal dominant), or epithelial sodium channel (ENaC) genes (SCNN1A/B/G; autosomal recessive). Milder clinical phenotype associates with ren...

Diagnostic and management practices of girls presenting with polycystic ovary syndrome (PCOS)-like symptoms to a tertiary paediatric endocrine clinic.

Solanas Martín Blanca , R. Howard Sasha , R. Hughes Claire , L. Storr Helen , H. Willemsen Ruben

Background: Polycystic ovary syndrome (PCOS) continues to be a diagnostic challenge in adolescent girls. Symptoms like oligomenorrhea and acne, and polycystic ovarian morphology on ultrasound can be normal variants in adolescents. In addition to diagnostic difficulties, there is lack of randomized controlled trials for PCOS treatments specific to adolescents. Current guidelines for diagnosis and management of PCOS in adolescents have large variations and rely ...

Hyperthyroidism leading to Idiopathic Intracranial Hypertension in a Child – A Case Report

Agrawal Pankaj , R Kapoor Ritika , A Chapman Simon , Wei Christina , R Buchanan Charles , Bhushan Arya Ved

Introduction: Idiopathic intracranial hypertension (IIH) is a rare neurological condition characterized by raised intracranial pressure (ICP) in the absence of hydrocephalus, brain parenchymal lesion, vascular malformation, or central nervous system (CNS) infection. Hyperthyroidism is a rare but known cause of raised ICP in children and adults, with only a few case reports in the paediatric population. We describe a 7-year-old boy with IIH associated with hype...

Disturbances of glucose homeostasis in polytransfused beta-thalassemia patients

Mustapha Noumi , N Khelafi , Y Ferhani , S Sokhal , R Terrak , R Boukari ,

Introduction: β-thalassemia is a hereditary chronic hemolytic anemia characterized by a defect in the synthesis of beta-globin chains, particularly common in the Mediterranean region, southern Asia, and the Middle East (1) Transfusion programs and chelating therapy have greatly extended the life expectancy of patients (2). This has led to an increase in the prevalence of endocrine complications, linked to iron overload (3) including abnormalities in gluco...

Thyroid Storm with Diabetes Insipidus: Management of A Rare Endocrine Presentation In A Child

Agrawal Pankaj , R Kapoor Ritika , R Buchanan Charles , Bhushan Arya Ved

Introduction: Thyroid storm is an acute, life-threatening, emergency in children with thyrotoxicosis. It is extremely rare and could be an initial presentation in previously undiagnosed children. Thyroid storm with diabetes insipidus (DI) has been reported in adults, but no cases have been reported in children. We herein report a child with thyroid storm with transient central DI.Case Report: A 7-year-old girl, presented...
