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...

Background: 46,XX gonadal dysgenesis is a rare condition linked to delayed puberty, absence of spontaneous pubertal development, and primary amenorrhea related to hypergonadotropic hypogonadism (Hh). External genitalia are typically female with no ambiguity. Although ovarian development is an active process with multiple gene involvement, the genetic etiology of this condition is usually unknown. DCAF17 has recently been implicated in the development ...

Introduction: Diagnosing a seizure can be tricky. The first thing a doctor should do is to rule out other conditions, such as non-epileptic seizures. One of these conditions may be metabolic disturbance as hypoglycemia. Growth hormone deficiency is commonly presented with short stature during childhood .hypoglycemia is a rare presentation of the disease.Case report: a four year and seven months male child, diagnosed as a...

Background: One of the speculated causes of the decreasing age of onset of type 1 diabetes is the increase in body weight in children. This so-called accelerator hypothesis is, however, controversial. The aim of the study was to test whether younger age of type 1 diabetes onset is associated with higher BMI-SDS at the time of diagnosis.Methods: Retrospective data analysis from medical records of all patients und...

The association of thyroid carcinoma with Graves' disease is considered rare and remains exceptional because it accounts for only 1-2% of childhood cancers.We report an observation of a 10-year-old girl from a goitrous endemic area (CHLEF) with exophthalmia. It shows signs of obvious thyrotoxicosis with with a very firm, homogeneous and asymmetrical goiter on the right.. A hormonal assessment, an echography and a thyroid scintigraphy confirm the ...

Background: With the inception of the Paediatric endocrinology training centre for Africa and West Africa a decade ago, several endocrinologists have been trained and are practicing in various part of Africa and Nigeria. The services and challenges faced are articulated in this survey.Objective and hypothesis: To determine the service delivery and challenges faced by paediatric endocrinology units in Nigeria.Method: A self-administ...

Background: Precocious puberty is defined as the onset of pubertal signs in girls younger than 8 years of age and in boys younger than 9 years of age. Central precocious puberty is due to an early activation of the hypothalamic-pituitary-gonadal axis. Different candidate genes were involved in the etiology of the disease. To date, mutations in the maternally imprinted gene MKRN3 are most frequently found in families with CPP.Objective and hypotheses: The...

Background: Hot thyroid nodules are uncommon in children and adolescents. Hyperfunctioning adenoma do not always produce hyperthyroidism, but can precede the apparition of a truly toxic adenoma. Autonomous adenoma can be associated with mutations of TSH-R and some mutations of GNAS.Patients: Patient 1 presented mild clinical hyperthyroidism. Patients 2 and 3 were asymptomatic and had clinical euthyroidism. Examination revealed a unique isolated thyroid n...

Background: Neonatal diabetes mellitus (NDM) is a monogenic form of diabetes that occurs in the first 6 months of life. Infants with NDM do not produce enough insulin, leading to hyperglycaemia. An identified and potentially treatable form of monogenic diabetes is the neonatal diabetes caused by activating mutations of the KCNJ11 gene, which codes for the Kir6.2 subunit of the beta cell of the ATP sensitive potassium channel (KATP). The identification of KCNJ11 mutation has im...

Congenital hypothyroidism (CH) occurs in approximately 1:2,000 to 1:4,000 newborns, in Algeria newborn screening programs do not exist, untreated CH remains a significant health and societal challenge. We report the case of a girl of 12 years old reffered for a failure to thrive, speech deficit and persistant vomiting, On clinical examination her height was –3 SDs with a very delayed bone age and a BMI of 35kg/m2 associated with severe musculoskeletal deformities and cog...
