X-linked hypophosphataemia (XLH) is the most common form of inherited hypophosphataemic rickets, caused by loss-of-function mutations in the gene encoding phosphate-regulating endopeptidase homologue X-linked (PHEX), resulting in excess circulating fibroblast growth factor 23 (FGF-23).1,2 In children, clinical features include delayed walking, waddling gait, leg bowing, pain, spontaneous dental abscesses and growth failure. Current therapies do not treat the underly...

Hypothyroidism is the most frequent thyroid abnormality in DS. It can be either congenital, with or acquired at any age after birth. It can be clinical or subclinical disorder. More evidence is required regarding the progressive development of thyroid dysfunction with age.Aim and Methods: We measured thyroid function (Free T4 and TSH) and Anti TPO level in 37 infants with DS at birth, during their first year and after ~ 2.5 years of...

There is an intriguing association between DS and thyroid abnormalities, which include sub-clinical, overt hypothyroidism, hyperthyroidism, and positive thyroid Antibodies. The prevalence of these abnormalities varies considerably depending on the diagnostic criteria and the selected population which includes sample size and age group.Aim: To measure the prevalence of thyroid dysfunction and associated autoimmunity in children with Down ...

Background: Subclinical hypothyroidism is the most common in DS. Thyroxin administration to improve growth early in life is still controversial.We measured linear growth (BMI, height SDS (HtSDS) and weight gain/day ) in 3 groups of infants and young children with Down syndrome (trisomy 21) and divided them retrospectively into 3 groups according to their thyroid function. Group 1 (n = 25) with normal FT4 and TSH, group 2 (n = 20)...

Introduction: Type 1 diabetes mellitus (T1DM) is a chronic disease characterized by absolute insulin deficiency, it’s usually diagnosed in children and adolescents. According to a recent report from the International Diabetes Federation, Saudi Arabia has 14,900 children with T1DM. The incidence is increasing over the last years with prevalence rates of 48 per 100,000 in the eastern region. Parents play an important role in the management of T1DM in children. As a result, ...

Introduction: Hyperinsulinemic hypoglycaemia (HH) is the most frequent cause of persistent hypoglycaemia in neonates and infants. The most severe forms of HH are inherited and referred to as Congenital Hyperinsulinism (CHI). Hypoglycaemia is the main feature of CHI, and early diagnosis and immediate management are essential to reduce the high risk of neurological damage. Diazoxide is the mainstay of medical treatment, with surgery being an option in appropriate cases.<p cl...

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 ...

Objective: This study was designed primarily to estimate whether there is an association between neonatal anthropometric parameters on one hand and cord blood levels of insulin, leptin, IGF1 and lipid profile on the other hand in offspring of diabetic mothers.Method: A total of 60 full term infants of diabetic mothers and 40 healthy infants of non-diabetic women participated in the study. Detailed anthropometric assessment of the newborn, head circumfere...

Background: McCune-albright syndrome is clasiically defined by the clinical triad of fibroud dysplasia of bone (FD), café-au-lait spots and precocious puberty. It is a rare disease with variable presentation caused by somatic (non-germline) gain of function mutation in GNAS gene. It can affects both endocrine and non-endocrine tissue. In addition to precocious puberty, other hyperfunctioning endocrinopathies may be involved including hyperthyroidism, growth excess, cushin...

Background: Congenital hyperinsulinism in infancy (CHI) is the most frequent cause of persistent hypoglycemia in infants. The most common and severe form of monogenic CHI is caused by inactivating mutations in ABCC8 and KCNJ11 genes located on chromosome 11p15.1. On the ABCC8 gene; previous studies have shown that mutations were reported to be mostly localized in exon 28. There is no sufficient research in Egyptian population about different mutations in conge...
