Context: The mouse ERα−/− knock-out model and rare human ESR1 gene mutations identified to date have demonstrated crucial role of ERα in control of energy homeostasis and glucose metabolism. Subjects with ERα deficiency show features of estrogen resistance (ESTRR) with continuous linear growth in adulthood.Patient: We describe a 20-year-old female, with unknown family history, who presented...

Background: Childhood brain tumour survivors are at risk of developing endocrine secondary effects throughout lifetime. Transition between childhood and adult care is a critical moment during which patients may stop medical visits and treatments.Objective: To describe endocrine care transition in our cohort of patients with primary brain tumors followed from 2010-2015, who are ≥=18 years old by December 31st</...

Background: “Transient” Neonatal Diabetes Mellitus (TNDM) is a rare genetic beta cells dysfunction leading to hyperglycaemia that resolves in early childhood. About 80% of patients relapse during adolescence or adulthood. Glucose homeostasis had not been investigated in adulthood.Objective and hypotheses: To investigate insulin secretion and insulin sensitivity in adults affected with TNDM or in their 1st degree mutated relatives.</p...

Background: Pubertal virilization in a 46,XY DSD patient is generally due to partial androgen insensitivity, 5-alpha-reductase deficiency, or 17-ketoreductase deficiency. Recently, reports have identified virilization signs associated with NR5A1/SF-1 gene mutations.Cases presentation and method: We present two unrelated cases of pubertal virilization due to NR5A1/SF-1 gene mutation. Both were suspected to be primarily affected by 5-alph...

Background: Partial androgen insensitivity syndrome (PAIS) covers a large spectrum of phenotypes, with the common denominator being insufficient virilisation of the external genitalia in an XY child with normal testosterone (T) production. Genetic diagnosis of PAIS is based on the identification of an androgen receptor (AR) gene mutation.Aim: The aim of this work was to determine whether the PAIS-like phenotype is associated with other gene mutations.</p...

Background: The clinical diagnosis of partial androgen insensitivity syndrome (PAIS) should be systematically considered for all 46,XY newborns/infants with undervirilisation contrasting with normal/elevated plasma testosterone levels. Confirmation of PAIS is based on the identification of an androgen receptor (AR) gene mutation.Aim: This work was undertaken to determine whether the minor forms of undervirilisation such as isolated hypospadias, isolated ...

Background: Pubertal gynecomastia is observed in up to 65% of adolescent males. It is usually idiopathic and tends to regress within 1–2 years, although sometimes pubertal gynecomastia persists.Case presentation and methods: We investigated three adolescent males with isolated persistent pubertal gynecomastia: twin brothers and an unrelated adolescent boy. The twins (17 years) had normal male external genitalia. Biological testing showed normal test...

Background: Congenital hypothyroidism (CH) is the most common neonatal endocrine disorder, with an incidence of 1:3000 neonates, and one of the most frequent preventable causes of mental retardation worldwide. Most (65%) cases of primary permanent CH are due to thyroid dysgenesis (TD). However, a genetic cause is identified in less than 5% of CH due to DT.Methods: We performed WES (Whole Exome Sequencing) for siblings with childhood-onset TD and we analy...

Background: For young adults with type 1 diabetes, transition from a paediatric setting to an adult care setting is a vulnerable period with risks for gaps in care. These emerging adults need to develop skills for managing their diabetes yet it is often challenging to cover all anticipatory guidance topics related to type 1 diabetes. In the context of a structured transition clinic, we hypothesized that by leveraging teens’ facility with technology and marketing/design we...

In young girls, the occurrence of secretory ovarian cysts may be the first manifestation of Mc Cune Albright Syndrome. We reported the evolutive profile of 8 patients with peripheral precocious puberty (PP) with (n=5 cases) or without metrorrhagia (n=3). On the first episode, they were 3.8 years old (range 2.5 to 7.25 years), the average diameter of the ovarian cyst was 38.5 mm (range 25 to 88 mm), the mean estradiol level was 32.5 pg/ml (range 3 to 160), mea...
