Introduction: HNF1B belongs to the organogenesis gene family. HNF1B is a rare autosomal disorder affecting early embryonic development of the urogenital tract, liver, pancreas and parathyroids. It is responsible for kidney damage and MODY type diabetes. It affects the female genital tract with a prevalence of uterine malformations of about 20%. To date, no study has evaluated the ovarian function or the gyneco-obstetrical profile of these patients.<p class...

Background: In 2011, nationwide growth charts were introduced, replacing different regional references (ZLS, Prader 1989; Sempé 1979 and, for BMI only, Kromeyer 2001).Objective and hypotheses: The aim was to examine the influence of new growth charts (WHO 2010) on the prevalence of nutrition- and growth-related disorders compared the ‘old’ references.Method: 6007 anonymised weight and height datasets of children meas...

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...

Background: We previously found that mast cells are present in the human adult adrenal gland with a possible role in the regulation of aldosterone secretion in both physiological conditions and aldosterone-producing adrenocortical adenomas responsible for primary hyperaldosteronism.Objective and Hypotheses: The aim of the present study was to investigate the presence of mast cells in the human fetal adrenal gland, and to provide arguments in favor of the...

Background: Prader-Willi syndrome (PWS) is a rare and complex genetic disorder characterised in neonates by hypotonia and feeding problems. French birth incidence has never been reported.Objective and hypotheses: To evaluate incidence of PWS at birth in France.Method: Identification of patients with a molecular diagnosis of PWS born between January 1st, 2013 and December 31st, 2013 was obtained by combining va...

We evaluated the growth parameters of 30 children with low weight gain who did not have any systemic illnesses and assessed their response to nutritional supplementation using two different formula supplements (1cal/1 ml) versus 1.5 cal/1ml) for one year.Patients and Methods: Thirty underweight children (BMI SDS < -1.5), aged 9 ±4 years, were divided into two groups according to the type of NS given by different dietitians. Group 1 included 10 c...

We analyzed the effect of having different BMI and BMI SDS, if any, on linear growth (HtSDS) in a cohort of prepubertal children (n = 102) in different BMI categories. In addition, we studied the effect of weight changes on linear growth in a randomly selected group of underweight children after nutritional rehabilitation (NR).Subjects and Methods: All prepubertal children between 1 and 9 years presented to the general pediatric clin...

Introduction: GDM prevalence is increasing worldwide. The aim of the study was to identify potentially modifiable predictors of adverse neonatal outcomes in women with GDM.Methods: This prospective observational study included 576 singleton multiethnic women diagnosed with GDM after 13 weeks of gestational age, followed in the Diabetes and Pregnancy Unit of the CHUV between 4/2012 and 2/2017. Predictors included HbA1c at booking after GDM diagnosis and a...

Background: GNAS gene is a complex imprinted locus, resulting in the expression of at least four transcripts (XL, NESP55, A/B and Gsα) characterized by their specific exon 1 and common exons 2-13. While Gαs is biallelically expressed in most tissues, XL is only expressed from the paternal allele. Maternally inherited, loss-of-function mutations affecting those GNAS exons that ...

Background: Tuner syndrome (TS) is associated with a distinctive cognitive profile including memory impairments. The current study focuses on metamemory defined as our knowledge about our memory functioning and yet never been explored in TS.Objective and hypotheses: The aim of this preliminary study is thus to determine what patients with TS know about their memory functioning and when their memory is impaired whether or not they are aware of those defic...
