Background: Type 1 DM (T1DM) is a chronic condition characterized by persistent hyperglycemia; which can impair immunity and increase susceptibility to infections. Latent TB infection (LTBI) is a subclinical infection caused by Myobactaeria tuberculosis antigens without clinical, bacteriological or radiological evidence of manifest TB disease. Tuberculin test (TST) is an inexpensive test used to identify LTBI status, but has limitations. False positive TST can...

Background: Osteopenia of prematurity (OOP) is serious but common concerns for parents of premature babies. Reduced bone mineralization results in OOP, or low bone density. The incidence of OOP has increased as a result of medical advancements that have allowed more very low birth weight (VLBW) infants to survive. It is inversely proportional to the intrauterine gestational age (GA).Objective: to study the risk factors a...

Background: Congenital hyperinsulinism (HI) is characterised by inappropriate insulin secretion despite low blood glucose which is commonly diagnosed in infancy (before the age of 12 months). Screening of the >20 known genes identifies a mutation in over 45% of cases. The likelihood of identifying a mutation in a known gene in individuals diagnosed after 12 months is not currently known.Aim: We aimed to identify the ...

SHOX deficiency causes a spectrum of clinical phenotypes related to skeletal dysplasia and short stature, including Léri-Weill dyschondrosteosis, Langer mesomelic dysplasia, Turner syndrome, and idiopathic short stature. SHOX controls chondrocyte proliferation and differentiation, bone maturation, cellular growth arrest and apoptosis via transcriptional regulation of its direct target genes NPPB, FGFR3, and CTGF. However, our u...

Aim: The objective of the study was to determine bone mineralisation density in Turner syndrome (TS) from DSD life cohort, and to analyse the trabecular (lumbar spine = LS) and cortical bone (femoral neck = FN) mineralisation.Materials and Methods: This study was part of the DSD-LIFE study, a cross-sectional clinical outcome study of the BMD of TS adult patients from paediatric cohorts. BMD of the LS and FN were ...

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...

Background: Children born small for gestational age (SGA) are predisposed to metabolic abnormalities. While the therapeutic benefit of recombinant human growth hormone (rhGH) therapy in improving height is widely recognised, it can affect carbohydrate metabolism, potentially inducing diabetes.Objective and hypotheses: This ongoing, prospective study aims to evaluate the long-term safety and efficacy of Omnitrope® (somatropin) in children ...
