It combines mainly hyperparathyroidism, adenomas of the pancreas and pituitary gland. The prevalence is about 2/100 000. Diagnosis in children is rare except in the case of family screening. We report the diagnosis of a familial MEN1 whose index case was an adolescent girl investigated because of hypoglycae...

Introduction: Severe insulin resistance due to insulin receptor mutation is usually diagnosed at the neonatal period (Donohue and Rabson-Medenhall syndromes), or later in a type A insulin resistance syndrome. We report here two cases of insulin receptor mutation whose presenting signs were less noticeable.Observation: A 13-year-old girl was referred for short stature (Height −2.5 SDS) with SGA (birth length 44.5 cm, at gestational age 41 weeks). Cl...

TSH, Free T3, Free T4 were in the normal range and thyroid autoantibodies were neg...
