Background: Thymus transplantation is undertaken for conditions associated with severe immunodeficiency. These comprise a number of genetic and syndromic associations including 22q deletion syndrome, CHARGE association, diabetic embryopathy, and other rarer conditions. Autoimmune thyroid dysfunctions (Hashimoto's thyroiditis and Graves' Disease) are described in the literature as the most common autoimmune disease after thymic transplant.<p class="...

Background: Thymus transplantation is undertaken for conditions associated with severe immunodeficiency. These comprise a number of genetic and syndromic associations including 22q deletion syndrome, CHARGE association, diabetic embryopathy, and other rarer conditions. These conditions may also be associated with hypoparathyroidism and patients are therefore at risk of severe hypocalcaemia. There are no published guidelines for calcium replacement in these patients during the ...

Background: Non-idiopathic central precocious puberty (CPP) is caused by acquired or congenital hypothalamic lesions visible on magnetic resonance imaging (MRI), or associated with various complex genetic and/or syndromic disorders without visible lesions on MRI. We investigated the different types and prevalences of non-isolated CPP phenotypes in a large group of consecutive patients with CPP.Methods: This observational cohort study included all patient...

Background: Klinefelter syndrome (KFS) is a sex chromosomal disorder characterised by hypogonadism, progressive testicular failure, gynaecomastia and learning difficulties. Genital anomalies are rarely observed in KFS. Androgen insensitivity has been previously postulated, but not proven to cause genital ambiguity in KFS. Androgen receptor (AR) gene defects are reported in AIS, but have not been reported in children with KFS with mild hypospadias. We describe a novel ...

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: Vaginal agenesis (VA) in MRKH syndrome can be managed either by surgery or autodilatations.Objective and hypotheses: To compare different managements of MRKH-VA in terms of quality of life, sexual function, anatomical results and complications.Method: National Multicentric observationnal study including 130 patients older than 18, at least one year after completing VA management, from October 2012 to April 2015. 84 had ...

Background: Few studies have addressed the question of psychological impact and long term outcomes in MRKH patients.Objective and hypotheses: Our national multi-centric study aimed to assess MRKH patients’ experience concerning diagnostic announcement, treatment perception, impact on psychic functioning, socio-professional integration, affective and sexual life and quality of life.Method: First 40 MRKH patients aged 19–34...

Background: Nephrogenic syndrome of inappropriate antidiuresis (NSIAD) is a very rare clinical condition. Patients suffer from hyponatremia, hypo-osmolality with inappropriately elevated urinary osmolality and undetectable AVP levels. Activating mutations of AVPR2, the vasopressin receptor type 2 (V2R), induce a prolonged signaling of the intracellular cAMP/PKA pathway and cause NSIAD in patients.Objective and hypotheses: To describe a new phenotype in a...

Background: Isolated gonadal dysgenesis due to NR0B1 locus duplication is a rare cause of 46,XY DSD. Almost reported cases were a total gonadal dysgenesis with complete female phenotype associated with primary amenorrhea. Only two unrelated cases of isolated partial gonadal dysgenesis with molecular characterization have been reported. The risk of gonadoblastoma is high.Objective and hypotheses: Phenotype correlation study (clinical, hormonal, and histol...

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...
