Introduction: Adrenal insufficiency is relatively rare in childhood and adolescence. Signs and symptoms may be non specific; therefore, the diagnosis may not be suspected early in the course. It may be categorized as primary or secondary and congenital or acquired. Many etiologies have been reported worldwide of which CAH was the commonest etiology in children.Objective and hypotheses: To determine the clinical features and evolution of ...

Introduction: The intrauterine growth retardation (IUGR) is defined by weight and/or height below the 10th percentile of reference population curve.Goal: To determine the predictors of small size at the age of 2 yearsMethod: Longitudinal prospective study from 2012 to 2016. We followed the growth in height and weight of children born with IUGR at term up to the age of 2 years.<p class="abstext"...

Background: Growth hormone deficiency (GHD) is defined as a total or partial deficiency in the secretion of growth hormone (GH) by the somatotropic cells of the anterior pituitary. The exact prevalence of this condition is unknown in Algeria. In Europe and USA, it is estimated between 1/4000 and 1/10000. This variation is explained by clinical polymorphism, the limits of pharmacological stimulation tests for GH stimulation, problems in interpreting the diagnos...

Background: Recent work revealed two pathways in androgen biosynthesis, namely the classic and an alternative, the backdoor pathway. In this alternative pathway dihydrotestosterone is produced from 17-hydroxyprogesterone without the intermediacy of testosterone using mostly enzymes that are specific to the backdoor path. In the human ovary, regulation of androgen production plays a crucial role in normal physiology and in pathologies such as the polycystic ovary syndrome (PCOS...

Introduction: Differenciated thyroid cancer (DTC) is a rare disease in children and adolescents, it concerns approximatively 1.4% of all pediatric malignancies. Papillary thyroid carcinoma (PTC) is the most common subtype of DTC in pediatric as well as in adult with necessity of radio iodine therapy after surgery.Aim: The aim of our study is to evaluate follow up after iodine therapy in childhood patients treated for...

Background: Hypercalcaemia secondary to malignancy is rare in children and adolescents. Parathyroid hormone related peptide (PTH-rP) secreted by malignant cells increases bone resorption and renal calcium retention causing hypercalcaemia. We report 2 cases of hypercalcaemia of malignancy refractory to treatment with pamidronate and corticosteroids but responsive to treatment with Denosumab and Zoledronic acid.Case 1: A 17-year-old boy with epidermolysis ...

Background: Children with type 1 diabetes (T1D) and their parents need personalized i) information about the disease and glucose homeostasis and ii) knowledge and guidelines about diet and insulin therapy.Objectives: To set a complete educational program that allows children with T1D to improve disease management and daily life.Methods: Education modules were written and trained with children and parents at outpatient visits. Each ...

Background: Cytochrome P450 oxidoreductase (POR) deficiency (PORD) is a form of congenital adrenal hyperplasia (CAH) and results in steroid-production loss from cytochrome P450 proteins. Mutations in POR cause mild to severe forms of CAH with/without bone malformation symptoms resembling Antley-Bixler syndrome. We report a novel POR Arg550Trp mutation identified in a 46,XX patient with signs of aromatase (ARO) deficiency. Child (first pregnancy) and mother pr...

Introduction: Cortisol homeostasis dysregulation has been associated to essential hypertension in adults. Higher levels of cortisol have been described in preterm-born individuals, who have also a higher risk of hypertension at younger ages. Several enzymes modulate peripheric cortisol metabolism. The 11b-hydroxysteroid dehydrogenase (11b-HSD) type 2 metabolizes cortisol into cortisone, preventing mineralocorticoid receptors’ activation by cortisol. The i...

Background: Heterozygous mutations in the Aggrecan gene (ACAN) cause autosomal dominant short stature with bone age (BA) acceleration, and premature growth cessation.Objective and methods: To characterize the phenotypic spectrum, associated conditions and describe response to growth-promoting therapies, detailed clinical evaluation of 73 mutation positive individuals from 16 families different families with heterozygous ACAN mutations was perfor...
