Introduction: Perrault syndrome (PS) is a rare disease characterized by a premature ovarian failure (with primary or secondary amenorrhea) and a sensorineural deafness. In this context we report the case of two sisters issuing from consanguineous parents presenting the association of these two anomalies.Cases: The reason for consultation was primary amenorrhea in both cases at age 16 and 21 years respectively, on examina...

Introduction: Allgrove syndrome is a genetic disorder of autosomal recessive inheritance associating in its complete form: Esophageal achalasia; alacrymia and adrenal insufficiency. This is generally an adreno-corticotropic hormone (ACTH) resistant. In this context we report the case of a patient followed in the endocrinology department.Case: This is the case of a boy who comes from a consanguineous marriage, with family...

Introduction: Congenital growth hormone deficiency (GHD) is a non-exceptional cause of short stature. The objective of our study is to re-evaluate the clinical, biochemical, and evolutive features of congenital GHD in Tunisian south in adulthood.Subjects/Methods: We underwent a retrospective study of 48 patients over 16 years old affected by GHD over 28 years (1990- 2018).Resultats...

Introduction: Early puberty is defined in the girl by the appearance of secondary sexual characteristics before the age of 8 years. Unlike the boy, the central origin is most often idiopathic. The familial nature encourages looking for a genetic mutation which can explain this early maturation of the gonadotropic axis.Cases: These are three girls from a consanguineous marriage. They had no particular pathological anteced...

Introduction: Sexual disorders 46 XY are responsible for a range of phenotypic disorders; from an ambiguous phenotype to a complete female phenotype. This is often a sporadic condition. In this context, we report 5 cases of gonadal dysgenesis, 46 XY belonging to the same family and particular phenotypic expression. this particular phenotype arise a question about the link between familial sexual differenciation disorders and the panel of genes involved in sexu...

Introduction: Leydig cell hypoplasia (LCH) or agenesis, is an autosomal recessive condition and a well-defined form of 46,XY disorder of sex development (DSD) resulting from inadequate foetal testicular Leydig cell differentiation.Inactivating mutations in the luteinizing hormone/chorionic gonadotropin receptor (LHCGR) gene account for the underlying LCH pathogenicityCase report: We studied a 15-ye...

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: An increase in the incidence of congenital hypothyroidism (CH) with a normally located gland has been reported worldwide. Affected individuals display transient or permanent CH during follow-up in childhood. We aimed to determine the prevalence of transient CH and to assess the possibility of distinguishing between transient and permanent CH in early infancy.Methods: This observational cohort study included all patients identified by systemat...

Background: The mechanisms responsible for inappropriate insulin release from β-cells in congenital hyperinsulinism in infancy (CHI) have largely focused upon defects in KATP channels. Little is known about insulin biogenesis, the profiles of insulin in insulin-containing secretory granules or whether the impact of KATP channel defects is the same in diffuse- and focal disease.Objective and hypotheses: To define the ultrastruct...

Background: α-klotho is a transmembrane protein which can be cleaved and act as a circulating hormone. Since low α-klotho levels were found in organic GH deficiency (GHD) and high levels in acromegaly, an interaction between α-klotho, GH and linear growth has been suggested.Objective and hypotheses: We investigated the role of α-klotho protein as a reliable marker of GH secretion in short children and the factors influencing its secre...
