Background: Genetic and epigenetic alterations at the GNAS locus are responsible for the Gsα protein dysfunctions causing Pseudohypoparathyroidism (PHP), a heterogeneous disease characterized by multiple hormone resistances and AHO signs (short stature, obesity, round face, brachydactyly, subcutaneous ossifications and mental retardation). A clinical overlap among molecular subtypes of the disease (Ia, Ib, Ic and II) makes the current classification inadequate; furthermor...

Introduction: Graves-Basedow disease (GD) is the most common cause of thyrotoxicosis in pediatric age. Multi-factorial pathogenesis stand on the basis of the autoimmune disorder activation, leading to lymphocyte imbalance that include increased CD4+ and CD8+ subtypes, increased CD4+/CD8+ ratio and B cells dysregulation. The aim of this study is to determine the potential prognostic value of lymphocyte population parameters in pediatric GD.<p class="abstext...

Introduction: Precocious Peripheral Puberty (PPP) due to autonomous ovarian activation is the most frequent endocrinopathy in girls with McCune-Albright Syndrome (MAS). Main goals of treatment for PPP are to reduce signs of estrogen exposure, also improving final height, and mitigate secondary psychological influence of sexual hormones exposure. This retrospective study analyzes the long-term safety and efficacy of letrozole treatment in a cohort of girls with...

Background: OTX2 is expressed in the human brain and plays a key role in the eye development. OTX2 mutations are reported in patients with ano/microphtalmia, optic nerve or optic chiasm hypoplasia, ocular coloboma and retinal dystrophies, associated in some cases with brain or pituitary abnormalities.Objective and hypotheses: Most of OTX2 mutations are nonsense or frameshift, more rarely missense mutations occur.Method: We...

Cornelia de Lange syndrome is a genetic disorder with physical, cognitive, somatic and endocrine disorders. Objective. To study endocrine and mammary disorders in girl with Cornelia de Lange syndrome. Objective and hypotheses: We describe a clinical case of Cornelia de Lange syndrome in girl, 10 y.o.Method: Total examination (includingmammological and gynecological examination), hormonal analysis, thyroid, mammological and gynecological ...

Pseudohypoparathyroidism (PHP) is an hereditary disorder characterized by resistance to parathyroid hormone (PTH) and in varying degrees to TSH, GHRH and FSH/LH, and caused by loss-of-function mutations in the GNAS gene, encoding the membrane protein Gs-alpha. Pathognomonic of these patients is a dysmorphic phenotype, called Albright's Osteodystrophy, which includes short stature, obesity, round face, mental delay, subcutaneous ossifications and brachydactyly. The most fr...

Background and objective: Pseudohypoparathyroidism (PHP) refers to a heterogeneous group of rare endocrine disorders caused by genetic or epigenetic abnormalities affecting the GNAS locus. It is mainly characterized by resistance to PTH and TSH and a complete or partial Albright Hereditary Osteodistrophy (AHO) phenotype. Few data so far exist on LH/FSH, calcitonin and glucose-lipid metabolism involvement, as well as on neurocognitive aspects. The aim of this multicentre study ...

Introduction: Subacute thyroiditis or De Quervain’s Thyroiditis is a self-limited inflammatory thyroid disease that is considered to be caused by a viral infection. Its incidence during the first decade of life is extremely rare. During the acute phase of the disease which lasts 2 to 6 weeks, the inflammatory process results in a temporary release of thyroid hormone with biochemical hyperthyroidism with or without symptoms. This phase is followed by a period with failing ...

Introduction: Le diabète de type 1 est l’endocrinopathie la plus fréquente chez l’enfant. Son incidence est en nette progression dans le monde. L’enfant diabétique nécessite une hygiène de vie adaptée et le suivi par une équipe pluridisciplinaire composée de pédiatre spécialiste en diabétologie, psychologue, diététicien, infirmier spécialisé.Objectif: Determiner les...

Background: The clinical phenotype of the chromosome 2q31 deletion syndrome consists of a variety of limb abnormalities and other skeletal defects, craniofacial dysmorhic features, developmental delay, and other not specific congenital anomalies.Objective and hypotheses: To describe a patient with 2q31.1 microdeletion syndrome and short stature, diagnosed with GH deficiency.Method: We describe a 5 years and 4 months girl with devel...
