Background: Van Wyc-Grumbach syndrome is a rare presentation of long standing pre-pubertal hypothyroidism characterized by bilateral multicystic ovaries, vaginal bleeding and delayed skeletal growth in case of female.Case Presentation: we present a clinical course, diagnosis and management of a case of Van Wyc-Grumbach syndrome in a 10-years old Egyptian counselled for recurrent vaginal bleeding and pubertal advancement for age. She was ...

Introduction: Since 1960, enlarged polycystic ovaries associated with hypothyroidism, delayed bone age and precocious puberty are recognized as Van Wyk and Grumbach syndrome. Although it is rare entity, it should be considered in differential diagnosis of the enlarged polycystic ovaries.Case: An eleven-year-old girl was presented with sudden onset of abdominal pain and vomiting. A large mass with multiple cysts was seen ...

Background: The association of primary hypothyroidism and isosexual precocious pseudopuberty in females was first described in 1960 by Van Wyk and Grumbach. The unique elements that lead to the diagnosis are FSH-dominated sexual precocity with non advanced bone age in the presence of hypothyroidism.Objective and methods: Describe an 8.5 years old girl with hypothyroidism due to HT and clinical and hormonal features of Van-Wyk and Grumbach syndrome.<p...

Background and hypothesis: The neonatal period is characterized by high urinary sodium loss, most notably in preterm infants that questions the ability of the mineralocorticoid pathway to maintain sodium homeostasis.Results: We have demonstrated that neonatal sodium wasting is associated with a physiological renal aldosterone resistance in relation to a low renal mineralocorticoid receptor (MR) expression at birth in full-term infants, both in humans and...

Background: Van Wyk Grumbach (VWG) and Kocher Debre Semelaigne (KDS) syndromes are rare syndromes with clinical manifestation of hypothyroidism associated with precious pseudo puberty and myopathic pseudomuscular hypertrophy. We present two cases that have the characteristic of both VWGS and KDSS syndromes developed in association with a long-term untreated hypothyroidism.Case 1: Seventeen years old girl was referred to our hospital due to menstrual irre...

Background: Ellis van Creveld syndrome (EVC) (chondroectodermal dysplasia) is a rare, multisystem disorder. It probably affects only around 1 in every 150,000 individuals. It is characterized by a long, narrow trunk and shortened arms and legs; extra fingers (postaxial polydactyly), and abnormalities of the oral region and teeth. In infants, non-bony manifestations, particularly congenital heart defects, may be health or life-threatening.Case presentatio...

Background: The syndrome consisting of primary hypothyroidism, precocious puberty, and massive ovarian cysts was termed Van Wyk and Grumbach syndrome (VWGS) in 1960. Chronic lymphocytic thyroiditis is the more common cause of hypothyroidism in children. In patients with severe longstanding hypothyroidism, the sella turcica may be enlarged due to thyrotrope hyperplasia. Puberty tends to be delayed in hypothyroid children in proportion to the retardation in the bone age, althoug...

Background: Unlike term neonates, known to exhibit a physiological pseudohypoaldosteronism, very preterms (VPT) display a high sodium waste at birth with partial aldosterone deficiency. This context, combined with a low aldosterone/renin ratio is highly suggestive of a defect in mineralocorticoid biosynthesis.Objectives and hypotheses: To investigate mineralocorticoid and glucocorticoid pathways in newborns, and to clarify the impact of prematurity upon ...

XY individuals with Disorders/Differences of Sex development (DSD) are characterized by reduced androgenization caused, in some children, by gonadal dysgenesis or, more rarely, testis regression during early fetal development. The genetic etiology for most patients with 46,XY gonadal dysgenesis and for all patients with testicular regression syndrome (TRS) is unknown. Identification of novel genes involved in DSD is crucial for providing an accurate clinical diagnosis, aiding ...

Background: Human scalp hair is a valuable matrix for determining long-term cortisol concentrations, with wide-spread applicability in clinical care as well as research. However, pediatric reference intervals are lacking.The aim of this study is to establish age-adjusted reference intervals for hair cortisol in children aged 0-18 years and to gain insight into hair-growth velocity in children up to 2 years old.Methods: A...
