Background: Achondroplasia is the most common cause of genetic dwarfism with a prevalence of 1/10 000 to 30 000 birth. It is a pathology of dominant inheritance linked to the mutation of the receptor gene growth factor on chromosome 4p16 fibroblastes FGFR3 responsable rhizomelic dwarfism and multiple complications likely to compromise the functional and vital prognosis of patients.Objective and hypotheses: Find the frequency of neurological complications...

Background: Dysfunction of the parathyroid gland is a rare cause of hypocalcaemia. It may be caused by a deficiency or resistance to PTH. Generally symptomatic It can be hereditary, congenital or acquired.Objective and hypotheses: Analysis of clinical, paraclinical, etiological and progressive children’s and adolescents hypocalcaemia by parathyroid dysfunction.Method: This is a retrospective study of hypocalcaemia by parathyro...

Background: The hyperandrogenism in the teenager is a frequent reason for consultation. It poses diagnostic problems and sometimes therapeutic ones.Objective and hypotheses: Search of the incidence and aetiology of hyperandrogenism in children and adolescent.Method: This is a retrospective study of patients hospitalized for exploration of hyperandrogenism. 14 patients was for collected, all underwent to a profound clinical examinat...

Background: Hormone deficiency no or late treated causes delayed puberty and reduced final height.Objective and hypotheses: Assess the progress of puberty in isolated GH deficient (GHD) patients.Method: 34 patients with GHD in puberty were followed in endocrinology. The average age at diagnosis of GH deficiency was 8±2.4 (7–19) in girls and 9±1.2 (8–18) in boys. The majority of patients received an irregular GH ...

Background: Turner syndrome (TS) is the most common chromosomal abnormality in females (prevalence 1/2500 births). It is related to the absence or abnormality of one of the two X chromosomes. It is characterized by a short stature, gonadal failure and a many diseases that reduce life expectancy of patients.Objective and hypotheses: Report Clinical, hormonal, Cytogenetics and evolutionary ST characteristics then correlate the karyotype and clinical expres...

Background: Recent studies using data from the International Congenital Adrenal Hyperplasia (CAH) Registry (www.i-cah.org) (1), have provided valuable insight into the determinants of reported acute adrenal insufficiency (AI) related adverse events, demonstrating that the I-CAH Registry can be used as a tool to create clinical benchmarks in CAH care.Methods: Care quality reports were created for 32 centres who participat...

Severe hypercalcemia with total serum calcium concentrations above 15 mg/dL is a serious nonspecific life-threatening emerging disorder. Hypercalcemia usually results in nonspecific classic gastrointestinal and skeletal symptoms as anorexia, nausea, weakness, polyuria, constipation and bone pain. It can be associated with metabolic, nutritional, inflammatory, genetic or malignant disorders, or can be drug-induced. Malignancy related hypercalcemia develops more aggressively and...

Introduction: The diagnosis and treatment of patients with rare diseases is often difficult as most clinicians do not encounter them. Therefore, centralization and collaboration between centers of expertise is necessary. European Reference Networks (ERN’s) such as RareEndoERN provide a platform for this, with one of its main thematic groups having a specific focus on rare growth and obesity disorders. Genetic obesity encompasses a heterogeneous group of c...

Pseudohypodosteronism type 1 (PHA-1) is an inherited disease caused by the resistance of peripheral tissues to aldosterone, leading to severe salt loss in infants. This rare disease is caused by mutations in the amiloride-sensitive epithelial sodium channel subunits (ENaCs). Loss-of-function mutations in ENaCs lead to PHA-1, which is associated with neonatal salt wasting. PHA1 can be transmitted as autosomal dominant and recessive forms. Patients with the autosomal dominant fo...
