Background: Congenital adrenal insufficiency represents a life-threatening condition. Among its multiples causes, mutation of NNT1 is the most recently discovered. We had the opportunity to observe one case. NNT1 is a gene coding for a membrane protein which protects cells from oxidative stress.Objective and hypotheses: As few cases have been published until now, we describe a new case.Results: In a consanguineous (second grade) Al...

Background: More than 20 gene loci are known to cause monogenic neonatal diabetes today. A definite mutation can be found in 65–70% of all cases. Mutations in the ATP sensitive potassium channel can frequently be treated by sulfonylurea. Glibenclamide is on of the drugs known to inhibit the bile salt export pump (BSEP). However most drug induced cholestasis cases are reported in adults.Objective and hypotheses: Glibenclamide is used frequently to tr...

Background: There are studies supporting the seasonality of diabetes according to date of diagnosis and date of birth, with most T1D children being diagnosed in fall and winter and most of them been born in the same period. That is in concordance with previously published data from 1978 to 2008 in our country.Objective and hypotheses: To assess whether there is a seasonal variation of diabetes onset according to date of diagnosis and date of birth of inc...

Background: Patients with 45,X/46,XY mixed gonadal dysgenesis (MGD) have variable phenotypes leading to both male and female sex assignments. A multidisciplinary team should guide the process of sex assignment, however a standardized approach may provide objective guidance for the team as well as a tool for settings without such resources. One of the most important considerations for sex assignment is the hormonal production, which often determines the degree of virilization. ...

Background: Congenital hypopituitarism (CH) in the neonate which manifests as the deficiency of one or more pituitary hormones can be presented by a highly variable phenotype. Either as isolated hypopituitarism or with associated developmental defects such as ocular, midline, and genital abnormalities. Mutations in genes encoding for a number of transcription factors have been described in a minority of patients with CH. This indicats that further genes remain to be identified...

Background: GH treatment in severe GH deficiency during the transition period is a key matter.Objective and hypotheses: To assess the outcome of 30 severe GH deficient (GHD) patients after a structured transition program, in a French Universitary Hospital between 1988 and 2014.Method: 30 patients treated with GH until final height for congenital deficiency: 16/30 (12 ectopic posterior pituitary), brain tumors: 11/30 (5 Rathke’...

Tricho-rhino-phalangeal syndrome Type I (TRPS I) is a rare autosomal dominant genetic disorder clinically characterized by craniofacial and skeletal abnormalities, associated with cone-shaped epiphyses, brachydactyly and short stature. Although patients with TRPS I present various degrees of short stature, there are only four reports of growth hormone deficiency in patients with TRPS I. We present the case of TRPS I and partial GH deficiency. A 15-year-old female was referred ...

Background: Obesity is increasing worldwide among adults, children and adolescents. The increase in obesity rates facilitated the development of several morbidities including impairment in glucose homeostasis. T2DM is described mainly among minority groups, and in Israel it is more frequent among the Arab population.Objective and hypotheses: We hypothesized that a correlation exists between the degree of obesity and impaired glucose homeostasis among Ara...

Background: Leptin is suggested to be a permissive factor in the onset of puberty by signaling at the level of the hypothalamus to indicate adequate energy stores. Overweight female rats due to increased neonatal nutrition have been shown to develop puberty before normal weight rats.Objective and hypothesis: We hypothesized that this permissive effect may be due not only to increased leptin levels, but also to increased hypothalamic sensitivity to this h...

Background: Childhood obesity is a serious public health concern. To identify risk for obesity in early childhood is important.Objective: To analyse association of pre-pregnancy maternal weight with BMI and metabolic profile at 4 years.Methods: 2604 pregnant mothers and 1960 children from the Spanish population-based cohort study Environment and Childhood (INfancia y Medio Ambiente) Project (INMA). Research protocol was approved by...
