Background: ROHHAD (rapid-onset obesity with hypoventilation, hypothalamic dysfunction, autonomic dysregulation) syndrome is a rare and underdiagnosed disease with high mortality rate. When a neural crest tumor (NET) is detected (56% of patients) the acronym used is ROHHADNET.Aim: To analyze the relationship between clinical variables, hypothalamic-pituitary disorders, DXA parameters and neural tumors, in ROHHADNET patie...

Background: Pseudohypoparahthyroidism is a rare genetic disorder that is characterized by unresponsiveness to parathyroid hormone and abnormal calcium regulation. Several subtypes have been established according to clinical appearance, resistance of other hormones, and recent genetic findings. Although little is known about the pathogenesis of heterotopic calcifications of soft tissues and brain, they are frequently found.Objective and hypotheses: Evalua...

Background: Disorders of Sex Development (DSD) comprise several phenotypes due to dysfunction in genes involved in human sexual determination and differentiation. The most frequent aetiologies among 46,XY DSD are androgen insensitivity syndrome and 5-alpha-reductase type 2 deficiency due mutations in AR and SRD5A2 genes, respectively.Objective and hypotheses: The purpose of this study was to investigate mutations in AR and ...

Introduction: Angelman syndrome is caused by de novo maternal deletions in 15q11-q13 region of chromosome 15 in approximately 70% of affected children.Patient and Methods: A two and a half year-old boy with hypotonia, absence of speech, low weight (-4.38 SDS) and short stature (-1.14 SDS) had pale skin and typical facial features with wide and prominent forehead, low-lying ears, wide mouth, small and widely spaced te...

Introduction: Recent publications report an earlier age of onset of pubertal changes in the US and Europe. Referrals to pediatric-endocrinologist for early puberty are increasing. Precocious puberty diagnosis is often delayed, especially in boys. Improvement in pubertal assessment (age at onset of puberty) by pediatricians and general practitioners is needed to participate in the PROSPEL study and to improve management of pubertal abnormalities.<p class="a...

Aims: Recently, our team introduced the concept of post-hypoglycemic hyperglycemia (PHH) in the context that recovery of hypoglycemia impacts cardiovascular risk. GLUREDIA study aimed to evaluate whether PHH parameters correlated with glycemic homeostasis during the first year after type 1 diabetes onset and helped to distinguish pediatric patients undergoing partial remission or not.Methods: In the GLUREDIA study, longi...

Aim: The aim of the study was to predict the risk of tumor recurrence in OBTMaterial and Methods: We conducted a retrospective, observational study (2001-2018) on the management of OBT in girls aged 0 to 18 at Toulouse University Hospital, France.Results: 68 patients were included. 16% were prepubertal. Mean age was 11.35 ± 3.08 years. Pain was the main symptom in 49% ...

Introduction: The genomic disorders caused by rearrangements in region 5q35, including the NSD1 (nuclear receptor SET domain containing protein-1) gene have various phenotypes depending on presence of deletions, duplications or inversions. Patients carrying microduplication have microcephaly, short stature, and mild to moderate intellectual delay or learning disability.Patients and methods: A six-year-old boy wa...

Introduction: Growth failure is a common consequence in small for gestational age (SGA) children.Patients and methods: The growth patterns and serum insulin like growth factor 1 (IGF1) concentrations before and after the 1st year under GH treatment of 32 short stature SGA born children have been evaluated. In addition, we investigated the insulin like growth factor 1 receptor (IGF1R) exon 2 as a hotspot for IGF1R genetic alterations. It is of note that n...

Key words: Primary hypoaldosteronism, aldosterone synthase deficiency, salt-wasting, failure to thrive, CYP11B2 gene mutationIntroduction: Aldosterone synthase deficiency is a rare autosomal recessive inherited disorder. The patients carry mutations in the CYP11B2 gene. It is primary hypoaldosteronism presented in early childhood with electrolyte abnormalities (hyponatremia, hyperkalemia, and metabolic ...
