About a case of familial hypocalciuric hypercalcemia (FHH) type 3 with neurological involvement

Hoth Guechot Helene , Kohler Florence , Humbert Linda , Kwapich Maxime , Francoise Odou Marie , Christine Vantyghem Marie

Background: FHH is a genetically heterogeneous condition mimicking primary hyperparathyroidism at the difference of low urine calcium excretion. FHH types 1, 2, and 3 are due to loss-of-function mutations of the CASR, GNA11, or AP2S1 genes, respectively. FFH 3, the rarest of the 3, is usually associated to 3 recurrent mutations affecting the arginine residue in position 15. The clinical phenotype has not been well described. We report a new case striking by the neurological in...

Gonadal dysfunction is associated with severity of disease in men with myotonic dystrophy type 1

hoth guechot Hélène , Humbert Linda , Kohler Florence , Leroy Clara , Robin Geoffroy , Vantyghem Marie-Christine

Background: The myotonic dystrophy type 1 (DM1) or Steinert disease is the most common inherited, autosomal dominant neuromuscular disorder in adult. The gonadal dysfunction has been known for many years in DM1 men with description of bilateral testicular atrophy but the factors influencing the different profiles of gonadal dysfunction, and their natural evolution are not clearly established. The purpose of this study was to determine the profiles of gonadal function on men af...

Introduction: Anti-thyrotropin receptor antibodies (TSHR-Abs) stimulating the thyroid (TSAb) are responsible for GravesÂ’ disease. In some patients, the TSHR-Abs can block thyrotropin action (TBAb) and cause hypothyroidism, the switch between stimulating and blocking activity in GravesÂ’ disease being well. This reports aims to describe clinical presentation of patients affected directly by hypothyroidism.Material and methods: Retrospective clini...

Background: APECED syndrome is a rare monogenic disease caused by homozygous mutation of AIRE gene. It classically presents with chronic mucocutaneous candidiasis (CMC), hypoparathyroidism (HP), and adrenal insufficiency (AI) with an early onset in childhood. Non-endocrine manifestations as ectodermic dystrophy, asplenism and pneumonitis are also observed but their incidence remains unknown and their mechanisms not well understood. APECED has been poorly reported in France alt...
