Background: Insulin resistance (IR) plays a larger role in type 1 diabetes (T1D) disease process than is commonly recognized. Dipeptidyl peptidase-4 (DPP-4) is an enzyme that is expressed on almost all cell surfaces. It deactivates many bioactive peptides involved in glucose regulation; glucose-dependent insulinotropic polypeptide and Glucagon-like peptide-1.Objectives: This study evaluates serum DPP-4 activity in adoles...

A 13 months old infant, presented with failure to thrive, untreated congenital hypothyroidism and pseudo-hypertrophy of limb muscles (i.e. Kocher-Debre-Semelaigne syndrome). The child had delayed motor and mental development. Thyroxin replacement therapy, as well as nutritional support, was initiated.Two to three weeks after treatment introduction, the motor and cognitive developments were accelerated with striking improvement as if global growth was sto...

Disorders of sex development (DSD) have defined as congenital conditions in which the development of chromosomal, gonadal, or anatomical sex is atypical. Wilms tumor 1(WT1) gene mutations have been described in 46,XY patients with ambiguous genitalia or complete gonadal dysgenesis with or without Wilms tumor, nephropathy, gonadoblastoma and other defects e.g. cryptorchidism, hypospadias. Sex chromosome mosaicism is a major cause of DSD with a wide phenotypic variability. The p...

Background: The prevalence of type 2 diabetes (T2D) is significantly increased in pediatric population, which is affected by obesity worldwide. The progression of insulin resistance to T2D in obese children has been shown to be faster than in adults. Therefore, screening for T2D seems meaningful especially in high risk groups such as children and adolescents with obesity, family history of T2D, and those with clinical features of insulin resistance (hypertension, dyslipidemia,...

Background: Many epidemiological studies have found high prevalence of vitamin D deficiency in children with type 1-diabetes mellitus (T1D). 1,25(OH)2D is a potent immune-modulator that also enhances the production and secretion of several hormones, including insulin. The association of low serum 1,25(OH)2D levels with high glucose level and diminished insulin sensitivity suggests that vitamin D may modulate insulin metabolism.Aim and objectives: To scre...

Langerhans cell histiocytosis (LCH) is a rare disorder of unknown etiology affecting the mononuclear phagocyte system. It is characterized by clonal uncontrolled proliferation and accumulation of immature dendritic cells in different organs. Affected cells express CD1-alpha and/or CD207 (Langerin) on immunohistochemistry. Although bone is the most commonly affected organ (80%), all other organs can be affected either alone or in combination. LCH is classified into Single syste...

Introduction: obesity is a major health problem worldwide and its incidence is increasing annually. Adipose tissue produces and regulates many hormones and cytokines which have relationship with obesity comorbidity. Serum level of vitamin D has been previously reported to have a negative relationship with obesity.Objective: To evaluate the relationship between vitamin D status and leptin, adiponectin, lipid profile and I...

Ovotesticular disorder of sex development (OT-DSD) is a rare disorder of sexual differentiation characterized by the presence of both testicular and ovarian tissues in the gonads of the same individual. Patients usually present at birth with ambiguous genitalia, and the majority showed a 46,XX karyotype, with absence of the SRY sequence. In this study we reported on nine patients with OT-DSD, who were referred to the Human Genetics and endocrinology Clinics, division ...

Background: Given that diabetes is an extremely common disorder in Egypt, the Diabetes Registry was designed by Pediatric Diabetes Clinic, Ain Shams University Hospital in the year 2010.Aim: Identify risk factors related to poor glycemic control and to provide data to health professionals for use in planning, evaluation, and optimizing diabetes care in those patients.Subjects and methods: The registry was designed to provide inform...

Introduction: Children with Growth Hormone deficiency(GHD) should be treated with r-hGH as early as possible after the diagnosis is made. The primary objectives of therapy is to normalize growth during childhood and to achieve final height within their genetic potential.Objectives: To determine impact of GH treatment on short term linear growth in the 1st year of therapy in children with isolated growth hormone deficienc...
