Introduction: Primary brain tumors are the second most common childhood malignancies, with an increasing survival rate over the years. Late effects on puberty and fertility alter survivors’ quality of life.Methods: We included 204 patients diagnosed with a primary brain tumor before 18 years, followed in pediatric endocrinology at the University Hospital “Necker-Enfants Malades” in Paris between January 20...

Background: The annual worldwide incidence of childhood adrenocortical tumors (ACT) ranges from 0.3 to 0.38/million children below the age of 15 years. Only 1–2% of them are feminizing ACT occurring in prepubertal boys and presenting with gynecomastia that normalizes after tumor removal.Case report: We present a case of a feminizing ACT. The boy was referred for bilateral gynecomastia, appeared 6 months before, at the chronological age (CA) of 7.5 y...

Background: Klippel–Feil syndrome (KFS) is characterized by congenital fusion of cervical vertebrae and has a prevalence of 1:50 000. The phenotypic expression is variable, sometimes presenting with extraskeletal symptoms.Case report: A girl was referred at the cronological age (CA) of 10.3 years with a suspected diagnosis of Turner syndrome, due to the presence of webbed neck and progressive deceleration of growth velocity. The girl, born in Russia...

Background: The association between primary hypoparathyroidism and celiac disease (CD) is uncommon in paediatrics, even more if they are not part of an autoimmune polyglandular syndrome (APS, almost exclusively type II). We describe a case of autoimmune hypoparathyroidism coexisting with celiac malabsorption.Objective and hypotheses: Valentina was a 7 year old female child when she was admitted in hospital because she had generalized seizures at home. Sh...

Background: Non alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in childhood, in obese subjects and associated with insulin resistance.FOXO1 is a key regulator in insulin signalling and in intracellular adipogenesis, and is implicated in liver steatosis. We have previously identified that a group of miRNAs are involved in its epigenetic regulation.Objective and hypotheses: We aimed to assess in liver tissue and in serum whe...

Background: Tuberous sclerosis (TS) is a polymorphic, dominantly inherited syndrome caused by an inactivating mutation in tumor suppressor genes, TSC1 or TSC2; they regulate mammalian target of rapamycin (mTOR), a key player in control of cellular growth and protein synthesis. The disease involves benign tumors in several distinct organs (such as the skin, kidneys, heart, and CNS), that can interfere with organ function. Rarely TS is associated with endocrine abnormalities, an...

Background: The diabetic ketoacidosis (DKA) represents one of the most frequent causes of death in childhood. The first therapeutic step is a quick rehydration, whereby a venous access must be ensured in every child with DKA, in order to infuse liquids immediately. The children conditions (state of shock, obesity) can make access extremely difficult. We present two cases of patients with severe DKA, where finding a venous access was almost impossible.Cli...

Central diabetes insipidus (CDI) in children is caused by brain tumors, Langerhans cell histiocytosis (LCH), trauma, infections, or genetic abnormalities in about 60% of the cases. In the remaining 40%, CDI is idiopathic even after detailed clinical and radiological investigations. Aim of the study was to assess whether measurement of serum antibodies against human growth hormone (GH) could aid in the identification of the etiological factors for CDI.<p class="abst...

Background: The diagnosis of GH deficiency (GHD) is not straightforward in childhood and adolescence, requiring comprehensive clinical, anthropometric, biochemical, endocrine, and neuroradiological assessment. Although pharmacological GH stimulation tests are still considered the gold standard for GHD diagnosis, they are burdened by both poor specificity and side effects. Several studies have addressed the issue of sensitivity and specificity of IGFBP-3 assess...

Background: Constitutional delay of growth and puberty (CDGP) is one of the most frequent norm variants in children presenting with short stature. Knowing the height, growth, and weight pattern of CDGP in the first years of life is important to distinguish CDGP from growth hormone deficiency (GHD) or other diseases.Methods: We studied height and weight in the first 5 years of life in 54 boys with CDGP including measureme...
