Introduction: Pubertal growth is hormone dependent. The anthropometric (height, weight) and sexual (Tanner stage (TS)) changes are accompanied by growth in foot length. However, the relationship between changes in foot length and other anthropometry remains unclear. Our aim was to determine how changes in foot length relate to growth parameters (height and weight), self-rated TS and serum sex steroids.Methods: We used data from the Adolescent Rural Cohor...

Background: Mirror movements (MM) are frequently associated to Kallmann syndrome (KS). They are mainly observed in patients with ANOS1 (KAL1) mutations. MM have never been reported in ANOS1 mutated females. A defect in the contralateral inhibition of the pyramidal tract has been proposed as the mechanism of MM in KS but never demonstrated.Objective and hypotheses: To investigate the molecular mechanism of a familial case of gonadotropic deficiency in whi...

Background: U.V. radiation exposure is the major environmental risk factor for skin cancers. However, sun avoidance leads to inadequate vitamin D levels which impair bone health. Moreover, numerous studies linked decreased sunlight exposure to non-skin cancer incidence or survival.Objective and hypotheses: To compare sun habits in a cohort of paediatric patients with a history of malignancy to healthy controls. We hypothesized that sun exposure will be d...

Background and aim: Medulloblastoma is a highly malignant childhood brain tumor, requiring treatment with high dose cranio-spinal irradiation and aggressive chemotherapy. Survivors of are at high risk for multiple endocrine deficiencies, including growth retardation and growth hormone (GH) deficiency. Previous studies reported decreased final adult height in survivors of childhood medulloblastoma, with height standard deviation score (SDS) ranging from -1.9 to...

Introduction: Puberty is a very sensitive period in the life of every adolescent. Having enough knowledge about this physiological phenomenon would allow them to better understand the morphological and psychological changes and to better accept themselves. And therefore, to know how to distinguish between what is pathological and what is normal. This awareness is crucial to diagnose pubertal pathology in time. Hence the important role of school medicine in ens...

Introduction: The nutritional status of young breastfed infants is sometimes dependent on the nutritional status of their mothers. Investigation of poor infant weight gain should take into account possible nutritional diseases of the mothers including Biermer's disease.Objective: through a clinical case, remind the importance of exploring the nutritional status of mothers of exclusively breastfed infants with poor w...

Introduction: 46 XY sex development disorders are a group of rare congenital conditions in which chromosomal, gonadal or anatomic sex is atypical. Less than 20% of cases have a precise genetic diagnosis.We report here the case of a patient suffering from a 46 XY sexual development disorder secondary to the MAMLD 1 gene mutation.Observation: The patient is a nine month infant who was admitted fo...

Background: Endocrine deficiencies, including impairment of the hypothalamic-pituitary-gonadal axis (HPGA), are found in the majority of survivors of medulloblastoma, due to high-dose craniospinal irradiation and gonadotoxic chemotherapy. Data regarding HPGA function in survivors of medulloblastoma is limited to small groups of patients and focusses mainly on female survivors. Furthermore, few studies investigated specific risk factors such as treatment protoc...

Background: The blood-brain barrier (BBB) is a multicellular neurovascular unit (NVU) that allows selective passage of necessary molecules into the central nervous system (CNS) while limiting the entry of neurotoxins and most drugs. A cross talk with pericytes and neural cells mediates the acquisition of tight junctions (TJs) in brain microvascular endothelial cells (BMECs), which limit the paracellular passage of solutes, thereby regulating CNS homeostasis. H...

Context: Non-classic congenital adrenal hyperplasia (NCCAH) diagnosed in childhood, whether treated or untreated, could pose an increased risk of obesity and metabolic derangements in adolescence and early adulthood. Both sustained hyperandrogenism and chronic glucocorticoid therapy may affect body composition. However, little is known about the body composition of subjects with NCCAH and its contribution to the development of adverse metabolic outcomes. <...
