Background: Analysis of insulin-like growth factor-I (IGF-I) is an important tool in the diagnosis of growth hormone deficiency. However, there are significant differences between IGF-I assays and normative data sets, which may have important clinical implications. The aim of this study was to investigate the difference in Z-scores between the iSYS-IDS reference values and the reference values for the IGF-I specific assay used in children.<p class="abstext...

Introduction: Short stature is the one of the most common referral to paediatric endocrine clinic. Analysis of growth charts is a non-invasive tool and should allow differentiation between normal and abnormal growth. The aimof thid study is to compare the accuracy of Algerian growth charts (DZ-charts) with WHO growth charts in identifying short stature.Method: Measurement of children and adolescents aged from 6 to 14 yea...

Introduction: The diagnosis of growth hormone deficiency (GHD) in childhood is challenging, because of the lack of a true gold standard and the relatively poor performance of available diagnostic testing. Many young children undergo unnecessary growth hormone stimulation tests (GHST).Objective: The aimof this study was to design and validate a predictive Score to diagnose children with GHD....

Background: Triple A syndrome (AAAS, OMIM#231550) is a very rare inherited disease characterized by the association of chronic adrenal insufficiency, achalasia, alacrima and central and peripheral neurological disorders. It is caused by mutations in the AAAS gene which encodes the nuclear pore complex scaffolding protein ALADIN. The relative prevalence and genotype of AAAS in the Maghreb countries has not been ascertained.Objective and hypotheses: To est...

Background: Congenital adrenal hyperplasia (CAH), resulting from mutations in CYP11B1 (gene encoding 11β-hydroxylase), is a rare autosomal recessive disorder due to an impairment of the last steroidogenesis step. Consequences are a decreased cortisol secretion, elevated plasma levels of ACTH, and accumulation of steroid precursors responsible of hyperandrogenism and hypertension. It is the second most frequent cause of CAH after 21-Hydroxylase de...

Screening for congenital adrenal hyperplasia through the measurement of 17-hydroxyprogesterone on the neonatal blood spot, aims to: prevent neonatal deaths; allow earlier identification and thereby decrease the severity of the initial salt-wasting episode; and to shorten the time during which a severely virilized genetic female newborn may be assigned the male sex. It is now practiced in most high-income countries, although the positive predictive value of the test is very low...

Introduction: 21-hydroxylase deficiency (21-OHD) is the most common cause of female virilisation at birth and carries heavy psychosocial consequences. Early antenatal treatment with dexamethasone is successful in avoiding severe virilisation, thus reducing the need for surgery and improving psychological outcome.Objectives: To evaluate the feasibility and effectiveness of antenatal treatment in 21-OHD in a resource-limit...

Turner syndrome (TS) is the most common genetic disorder occurring in 1 / 2500 live-borne girls. It’s characterized by complete or partial loos of one X chromosome associated with short stature and premature ovarian failure. Morbimortality are increased in TS and related to cardiovascular (CV) disease. The aim of this study was to investigate the karyotypes and the phenotypes of a paediatric population with Turner Syndrome.Methods:...

Objectives: To examine age at presentation and outcome in children diagnosed with 21-hydroxylase deficient congenital adrenal hyperplasia (21-OHD CAH) in Algeria in the absence of a national neonatal screening program.Design: Retrospective analysis of patients followed in a single centre from 2007 to 2017. The diagnosis of CAH was established on clinical and biochemical grounds ± genetic analysis.Results: Of 168 patients (114F...
