Background: Pseudohypoaldosteronism (PHPA1) is a disorder of impaired renal electrolytes re-absorption and excretion. Primary PHPA1 has two clinically and genetically distinct forms: (i) Renal autosomal dominant form, which involves a mutation in the mineralocorticoid receptor; (ii) Systemic autosomal recessive form, which involves a mutation in the epithelial sodium channel. PHPA1 can be also transient secondary to urinary tract infections (UTI)/malformations.<p class="ab...

Objectives: Given the critical role of linear growth and peak bone mass attainment in childhood and adolescence, this study sought to elucidate the effects of a low carbohydrate diet (LCD) versus a Mediterranean diet (MED) on bone turnover markers (BTM) in adolescents with type 1 diabetes (T1D).Methods: In an open-label, randomized controlled trial, 40 individuals with type 1 diabetes, aged 12-22 years, were randomly ass...

Introduction: Parents of girls with Turner syndrome (TS) are coping with various challenges associated with caring for a child with a chronic disease.Aims: Explore the logic and importance of group support for parents of girls with TS.Methods: Group support sessions for parents of girls with TS were divided into meetings regarding psychological aspects, medical aspects, and social ...

Introduction: Diabetic ketoacidosis (DKA) is the most common cause of hospitalization, cerebral edema, and death among children with type 1 diabetes (T1D). Fatty acid-binding protein 4 (FABP4 or aP2) is one of the most abundant proteins in adipocytes and has been shown to be actively secreted from adipocytes. Circulating FABP4 is regulated by fasting- and lipolysis-related signals and contributes to hyperglycemia by promoting hepatic gluconeogenesis and interf...

Shox gene deficiency which causes short stature is a known indication for treatment with growth hormone. The prevalence of shox deficiency among children with idiopathic short stature has a high variability in different studies and ranges between 1.5-17%. We aimed to determine the incidence of SHOX haploinsufficiency in our region and to assess the genotype-phenotype relation which may help with setting criteria in the decision to which patients should we offer this genetic te...

Background: Congenital hypothyroidism is a common condition with reported incidence between 1/2000 – 1/4000 live births. In approximately 85% of cases this is sporadic due to a structural abnormality of the thyroid gland. Approximately 15% of cases are hereditary and secondary to thyroid dyshormonogenesis. Most of these are due to mutations in one of the genes involved in iodine transport or organification, mutations in the thyroglobulin gene or d...

Background: Pseudohypoparathyroidism (PHP) encompasses a group of rare disorders defined by target organ unresponsiveness to parathyroid hormone (PTH). Patients with PHP type 1A carry heterozygous mutations of the maternal GNAS gene that encodes the α-subunit of the G protein. This protein is coupled to the PTH receptor as well as to other heptahelical receptors - TSH, GHRH and gonadotropins receptors.Objective and hypotheses: To describe a...

Background: Mitochondrial disorders resulting from single large-scale mitochondrial DNA (mtDNA) deletions (SLSMDs) are a group of non-inherited congenital diseases that lead to three clinically overlapping syndromes: Pearson syndrome (PS), Kearns-Sayre syndrome (KSS), and chronic progressive external ophthalmoplegia (PEO). Although many reports have addressed endocrine abnormalities in patients with SLSMD, there hasn't been an in-depth study on these abno...

Introduction: Schaaf-Yang syndrome (SYS) is a rare neurodevelopmental disorder first identified in 2013, characterized by features overlapping with Prader-Willi syndrome (PWS) but distinguished by unique symptoms, such as joint contractures and high rates of autism spectrum disorder (ASD). SYS is caused by pathogenic heterozygous variants in the paternally-derived MAGEL2 allele. We sought to describe a case series of three SYS patients, highlighting t...

Objectives: Angelman syndrome (AS) is a rare, genetic, neurodevelopmental disorder characterized by developmental delay with severe impairments in speech, motor and coordination dysfunction and unique behaviors, accompanied with distinct facial features and high prevalence of epilepsy and sleep problems. Despite few reports regarding short stature among AS patients, this feature has not been extensively studied and is not included in the clinical criteria defi...
