Context: Congenital adrenal hyperplasia (CAH) is a rare genetic defect. Its prevalence is estimated at one case per 3,000 births in Algeria and one case per 15,000 births worldwide. The most common form is due to 21-hydroxylase deficiency associated with mutations in the 21-hydroxylase gene, which is located at chromosome 6p21. Molecular defects of CYP21A2 systematically decrease the activity of this enzyme and result in expression of varying severity and phen...

Background: Leydig cell tumor (LCT) is a rare testicular tumor developing from male gonadal interstitium and most common type of testicular sex cord-stromal tumor. Its incidence is about 1%–3% of all testicular neoplasms. In children only few cases had been reported and are associated with pseudo puberty.Case report: We report a case of a 4 years old boy admitted to our unit for management of precocious puberty which started one year ago with increa...

Background: Graves' disease is a rare autoimmune disorder in children. Its incidence is 0.1/100,000 person-years in young children and 3/100,000 person-years in adolescents. It is related to the production of TSH-stimulating autoantibodies occurring on a particular genetic predisposition. The particularity of Graves' disease in children is the risk of relapse after medical treatment, which is more frequent than in adults with a frequency of around 30...

Background: Kenny-Caffey syndrome type 1 is a rare autosomal recessive syndrome caused by mutation in the TBCE gene (Tubulin specific chaperone E) located in the chromosome region 1q42-q43. Less than 60 cases have been reported in the literature especially in the Middle East and Arabic countries. This syndrome is characterized by growth retardation, dysmorphic features, with thickened bone cortex and medullary stenosis, hypoparathyroidism, teeth anomalies. Hypopituitarism with...

Context: The outcome of a treatment depends largely on the observance and compliance of the patient. Studies analyzing therapeutic compliance in chronic endocrine diseases are rare and especially controversial in childhood. Studies have reported poor adherence in 6-50% of cases.Patients and Methods: We studied treatment compliance in 100 children treated with subcutaneous growth hormone for growth hormone deficiency, int...

Introduction: The transition period between childhood and adulthood in patients with growth hormone deficiency is a vulnerable period during the follow-up. Different consensuses have established follow-up and reassessment protocols for this period in order to clarify whether GHD persists. The benefits of maintaining treatment during this period are widely documented on the metabolic, vascular, bone and in terms of quality of life and well-being.<p class="a...

Background: Clinical spectrum of 46 XY DSD is characterized by a greatest diversity. Atypical sex development can occur through different steps of testicular differentiation. Etiologies of 46 XY DSD are termed gonadal dysgenesis, hormonal dysfunction and action. Its global incidence is unknown but the most common presentation, hypospadias, is understood to occur in 1 in 125 male births, and complete androgen insensitivity has an incidence of 1:20,000 people.</...

Background: Nutritional rickets continues to be an important health care problem. Its incidence has decreased in our country following the free vitamin D distribution that started in 2005 but it continues to stay on the agenda as a preventable disorder.Aim: Our aim was to evaluate patients diagnosed with nutritional rickets following the vitamin D supplementation program.Method: We evaluated patients diagnosed with nutritional rick...

Background: Septo-optic dysplasia (SOD) is a congenital affection characterized by classic triade: optic nerve hypoplasia, hypothalamic-pituitary endocrine deficits and mdline abnormalities of the brain. It is typically diagnosed in infancy and has a variable presentation.Case presentation: The patient is an 5 year old Algerian girl. At birth, bilateral congenital nystagmus and strabism was noted? Right blindness was suspected by parents at age of 2 year...

The majority of individuals with disorders/differences of sex development (DSD) do not have a genetic etiology. However, recently new genes causing DSD have been reported and using the unbiased approach of whole exome sequencing (WES) the diagnostic yield should be improving. Here, we performed WES on a large cohort of 125 individuals all of Algerian origin, who presented with a wide range of DSD phenotypes. Parental consanguinity was reported in 36% of individuals. The geneti...
