Background: Neonates born from mothers with Graves’ disease are at risk to develop hyperthyroidism due to placental transmission of TSH-receptor antibodies. Neonatal hyperthyroidism should be effectively diagnosed and treated to prevent severe complications of this disease (cardiac symptoms, poor weight gain, severe neurological manifestations).Objectives: To describe the post-natal follow-up of neonates born from women with Graves’ disease.</p...

Background: Brain-Lung-Thyroid (BLT) syndrome (OMIM# 610978) is characterized by congenital hypothyroidism (CH), infant respiratory distress syndrome (IRDS), and benign hereditary chorea and is caused by thyroid transcription factor 1 (NKX2-1/TTF1) haploinsufficiency. The phenotype can be partial or complete and there is a large phenotypic variability.Objectives and hypotheses: Identify new genes in a selected group of patients presenting thyroi...

Background: Growth monitoring of apparently healthy children aims at early detection of severe underlying conditions. Strong empirical evidence shows that current practices of growth monitoring are suboptimal. Practice standardisation with validated tools requires answering two questions: Which conditions should be targeted? How should abnormal growth be defined?Objective and hypotheses: To obtain consensus on a short list of priority target conditions o...

Background: Homozygous mutations in the transcription factor RFX6 are the cause of the Mitchell-Riley syndrome associating neonatal diabetes, pancreatic hypoplasia, gallbladder agenesis, duodenal atresia, and severe chronic diarrhea. Nine cases have been reported so far and the condition has a poor prognosis with five of nine patients died before the age of 6 months.Objective and hypotheses: To report on the clinical management and outcome of tw...

Background: Screening for autoimmune thyroid disease in children and adolescents with type 1 diabetes lacks consensus. Optimal screening methods should benefit the patients and reduce costs to healthcare.Objective and hypotheses: To, at diagnosis of type 1 diabetes, determine the predictive value of thyroid autoantibodies, thyroid function, islet autoantibodies, and HLA-DQ for autoimmune thyroid disease.Method: At diagnosis of type...

Background: Patients with disorders of sex development (DSD) require multidisciplinary team management for etiology identification and gender assignment. Identification of mullerian structures is an important part of the evaluation process. Ultrasonography remains the first-line imaging modality to delineate mullerian structures; while the importance of magnetic resonance imaging (MRI) is insufficiently studied.Objective and hypotheses: To evaluate the d...

Background: The broad spectrum of associated diseases underlying the diverse phenotypes of patients with Turner syndrome (TS) has been extensively described. However, the underlying pathophysiological mechanisms remain unknown. Few studies have analyzed congenital and acquired diseases as a function of karyotype, and conflicting results have been obtained, calling into question the role of haploinsufficiency for genes located on the X chromosome.Objectiv...

Background and Aim: Vertebral fractures (VF) in children with acute lymphoblastic leukemia (ALL) are often symptomatic and impairing life quality. Prevalence of children with VF at ALL diagnosis has been reported as 16% with peak incidence occurring during the first year after diagnosis and a 6-year cumulative incidence of 32.5%. Moreover, only 15.8% of these patients will have vertebral reshaping 24 months after ALL diagnosis. Additionally, 23% of ALL survivo...

Introduction: Thyroid hormone resistance (THR) is a rare disease (&ap; 1/50000) mainly due to thyroid hormone receptor beta gene (THRB) mutations, generally identified in late childhood and adulthood. We report 2 atypical cases of neonatal diagnosis of THR.Case 1: The newborn presented with neonatal respiratory distress due to a voluminous compressive goiter, requiring invasive ventilation. Thyroid function test...

Background: Limbic encephalitis (LE) is a neurological disorder characterized with amnesia, seizures, personality changes. LE is usually considered as paraneoplastic disorder. Infections, paraneoplastic disorders and autoimmunity should be considered in LE etiology. Association of type 1 diabetes mellitus and LE is very rare. Here in we report a patient who was diagnosed with type 1 diabetes mellitus (T1DM) six months after LE occurrence.Case: A 17-year-...
