Introduction: Multinodular goiter (MNG) is a common disorder of the thyroid gland, characterized by thyroid enlargement due to the development of multiple hyperplastic nodules. It is infrequent in children. Here, we present the case of two families with novel DICER1 mutations and familial history of nodules in adolescence.Observations: A 10-year-old female presented a MNG. TSH, Free T3, Free T4 were in the normal range and thyroid autoantibodies were neg...

Background: Over 90% children grow normally, and attain final height within their genetic target. Up to 10% of all children do not spontaneously catch-up by the age 3 years, besides some cases of TS are diagnosed late, and others with SGA go undiagnosed and unattended.Objectives & Hypothesis: Early screening of growth patterns in children attending Child Protection Visits (PMI, France) in Dreux district. Our objective was the evaluation of prevalence...

Background: Pituitary stalk interruption syndrome (PSIS) is a frequent cause of congenital hypopituitarism. Patients are initially referred for the evaluation of hypoglycemia during the neonatal period or growth retardation during infancy or childhood. PSIS are either associated with extra-pituitary malformations (EPM+) or isolated (EPM−).Objective and hypotheses: To compare baseline characteristics, GH response, and long term evolution in patients...

Background: Severe primary insulin-growth factor-1 (IGF1) deficiency (SPIGF1D) is a rare cause of short stature. Diagnosis is based on low basal IGF1 concentration, short stature, normal or elevated growth hormone concentrations and absence of any secondary causes of growth failure. Thanks to advances in next-generation sequencing (NGS) technologies, genetic etiology of SPIGF1D is expanding.Objectives: • Identify th...

Introduction: Congenital adrenal hyperplasia is the most common cause of primary adrenal insufficiency. It is a rare monogenic recessive disorder. In African setting in absence of neonatal screening, the diagnosis is still late, based on a clinical approach. During this clinical enquiry, information form past history or pedigree of the patient are of a huge importance and may revealed surprisesPatients and methods: In th...

Background: The initiation of puberty is dependent upon an augmentation of gonadotropin-releasing hormone (GnRH) secretion from the hypothalamus. Development of the GnRH neuroendocrine network in embryonic life depends on coordinated migration of neurons from the vomeronasal organ in the nose to the forebrain. We have previously demonstrated that dysregulation in GnRH neuronal migration leads to delayed pubertal onset. Late puberty affects up to 2% of the ...

Introduction: Premature pubarche is the most frequent diagnosis when children present moderate pubic hair development, but other diagnosis must be ruled out. We report the case of a child with premature pubarche with hormonal results in the physiological range, corresponding to an adrenal tumor.Observation: A girl aged 6.8 years consulted for precocious pubertal development (pubic hair stage 3, breast stage 2), with moderate acne. There was no virilizati...

Background: In our bone unit, we were following since their younger age, two brothers with a severe osteogenesis imperfecta. We had no genetic confirmation but the severity of the disease combined with unaffected consanguine parents argues for a recessive autosomal transmission. Both present with highly severe form of osteogenesis imperfecta: repeated vertebral and peripheral fractures, long bone deformations, centromedullary nails on the lower limbs, major motor handicap and ...

Management of patients presenting a chronic endocrine or metabolic disease during transition period is a challenge for multiple reasons. The department of Adult Endocrinology and Reproductive Medicine in Pitie Salpêtrière Hospital, Paris has been involved in the management of such patients for many years. However, in our own experience, 81% of patients are still followed-up after 1 year, 71% after 3 years and only 49% after 5 years. Based on such experience, we decid...

Background: Non-classical congenital adrenal hyperplasia (NCCAH) may present during childhood, adolescence or even adulthood with various degrees of hyperandrogenism. Diagnosis is established through tetracosactide (Synacthen®) test and genotyping. Cortisol insufficiency has rarely been described in NCCAH.Objective and hypotheses: To describe cortisol response to tetracosactide test in NCCAH patients.Method: Retrosp...
