Background: A 10 year old girl with a background history of severe autism and developmental delay presented with significant and rapidly progressive asymmetrical breast enlargement accompanying her relatively rapid progress through puberty. There was associated tissue breakdown exacerbating her discomfort and leading to increasing problems with anxiety and behaviour.Objective and hypotheses: To explore the aetiology of the huge breast development and the...

Background: There are some studies about vitamin D level and type 1 or type 2 diabetes mellitus (DM). Its effect on metabolic control of patients with type 1 DM is the subject of this study.Patients and Method: In 339 patients with type 1 DM, 192 cases (99 males, 93 females) randomly enrolled in the study. The age of males was 9 ± 4.4 yr and age of females was 8.3±4.3 yr. Their HbA1C and 25(OH) D3 were measured by HPLC method. ...

Objectives and Study: To compare the bone mineral density (BMD) between children with cow milk protein allergy (CMPA) and those who are healthy as control subjectsMethods: This study was carried out on forty children with cow milk protein allergy attending the Alexandria University Children's Hospital nutrition clinic and compared to forty apparently healthy children of matched age and sex as a control group. Anthro...

The calcium-sensing receptor (CaSR) is a member of the G protein coupled receptor family. It is mostly found in the parathyroid gland and renal tubule. CaSR disorders occur with inherited or acquired mutations. Familial hypocalciuric hypercalcemia syndromes are associated with inactivating mutations in CaSR. The heterozygous form is “benign familial hypercalcemia” and the homozygous form is “neonatal hyperparathyroidism”. In this article, “benign ...

Pseudohypoparathyroidism (PHP) is a disorder caused by PTH resistance due to a genetic defect in imprinted GNAS cluster. It is characterized by high phosphorus, low to normal calcium and elevated PTH. It is classified into types 1a, 1b, 1c, pseudopseudohypoparathyroidism and type 2. Type 1a is often associated with Albright Hereditary Osteodystrophy (AHO) which is characterized by short stature, round facies, obesity, brachydactyly, ectopic calcifications and developmental del...

Background: Vitamin D Dependent Rickets Type IA (VDDR-IA) is the most common type of VDDR and caused by mutations in CYP27B1. Here, we aimed to analyze the genotypic and phenotypic features of our VDDR-IA patients.Materials and Methods: The patients with a clinical diagnosis of VDDR-IA were enrolled and analyzed for CYP27B1 gene mutations.Results: 12 (5 males) pat...

Objectives: Subclinical hypothyroidism (SH) is the most common thyroid abnormality in Down Syndrome (DS) children (25-60%); its etiology remains still not completely clarified. Aim of this prospective multicenter study was to evaluate prevalence and natural course of autoimmune and non-autoimmune SH in a large cohort of DS children and adolescents.Methods: The study population included 101 DS patients with SH (TSH 5-...

Background: To diagnose non classical congenital adrenal hyperplasia (NCCAH) and adrenal insufficiency (AI), current guidelines recommend ACTH test. Cutoffs for 17 hydroxyprogesterone (17OHP) and cortisol are derived from immunoassays values. Thanks to a recently developed and validated mass spectrometry approach (LC-MS/MS) we routinely quantify simultaneously 16 circulating steroids and we are able to speculate on new cut off values and uses.<p class="abs...

Introduction: Parathormone-related peptide (PTHrP) regulates tissue calcium concentration by acting in paracrine or autocrine ways. It is mostly responsible for paraneoplastic hypercalcemia seen in adults. Paraneoplastic hypercalcemia in children is rarely reported in cancers such as ALL, medulloblastoma and hepatoblastoma (0.4–0.7%). In experimental studies, PTHrP is shown to be synthesized apart from neoplastic tissue (glomerulus and tubule cells).<p class="abstext"...

X-linked hypophosphatemic rickets (XLH) is the most common form of hereditary rickets. It is caused by inactivating mutations in the PHEX gene (phosphate-regulating-endopeptidase-analog, X-linked), leading to increased fibroblastic growth (FGF-23) levels, responsible for the renal phosphate wasting. This results in hyperphosphaturia and hypophosphatemia, and altered bone mineralization, in the absence of vitamin D deficiency. Classical treatment consists on oral supplementatio...
