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: Congenital hypomagnesaemia is a rare autosomal recessive disease presenting with convulsions in the newborn period. Early diagnosis and treatment are required if neurodevelopmental delay is to be prevented.Materials and Methods: Retrospective study of patients with congenital hypomagnesemia followed in our department.Objective: To document the clinical presentation, d...

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...

Background: Steroid 11-β hydroxylase deficiency is the second most frequent cause of adrenal hyperplasia (CAH) with autosomal recessive inheritance. Girls have importantly virilized external genitalia at birth, and boys display precocious pseudopuberty. Unlike others enzymatic deficiency involved in CAH, there is no salt wasting during infancy but patients develop hypertension. Because of more than 90% of homologous sequence between CYP11B1 gene ...

Background: Congenital hypothyroidism (CH) is the commonest congenital endocrine disorder and the primary cause of treatable mental retardation. In low-income countries lacking newborn screening programs, CH remains a serious public health problem.Objective: To investigate the characteristics at diagnosis and clinical outcome of patients with CH in Algeria; and determine factors related to psychomotor development.<p ...

Background: The investigation of patients with 46,XY DSD is often difficult, with no definitive diagnosis in more than 50% of cases investigated. We describe a new mutation of MAMLD1 in a patient with 46,XY DSD who also showed an alteration in the NR5A1 gene.Case report: A 5-year-old boy was referred to our clinic for DSD. He was born to non-consanguineous parents and was diagnosed with ambiguous genitalia at birth but had not been previously investigate...

Background: Short stature and gonadal dysgenesis are the two characteristic clinical features of Turner syndrome (TS), but multiple systems may be affected.Aims: To evaluate TS prevalence in girls presenting with short stature; and to establish a correlation between karyotype and associated features.Subjects and methods: Retrospective study of all patients diagnosed with TS (December 2007–March 2013).Res...

Background: The steroidogenic enzyme aromatase is encoded by the CYP19A1 gene. Aromatase activity is required for estrogen biosynthesis from androgen precursors in the ovary and several extragonadal tissues. The role of aromatase and thus estrogens for human biology is best illustrated by disease states, both deficiency and excess which might be caused by genetic disorders.Aim: A novel deletion-insertion mutation spanning from intron 10 to the 3...

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: Disorders of sex development (DSD) are a group of rare conditions characterized by variable discordance between chromosomal, gonadal and phenotypic sex. An association between smallness-for-gestational age (SGA) and DSD is already recognised, but few studies have investigated this in detail.Aim of study: To evaluate the prevalence of SGA, among patients with DSD and to establish a correlation with the different types and causes of DSD.<p ...
