Background/Aims: 46,XY gonadal dysgenesis (GD) is classified as complete (CGD) or partial (PGD) depending on gonadal morphology and function. In contrast to the typical female external genitalia in CGD, the phenotype of PGD is variable depending on androgen production. A diagnosis of PGD is based on clinical/biochemical features, gonadal histology and genetic findings. The aim of this study is to characterise these features, particularly histological, in a lar...

Introduction: Congenital adrenal hyperplasia (CAH) is the most common genetic condition in the spectrum of differences of sex development (DSD). Surgery in DSD is a controversial topic and there is no consensus if to perform surgery, how to perform surgery, and when to perform surgery. The current study was designed to evaluate the current practice in CAH related surgical practice in girls.Patients and Methods: All cases...

Background: A national database has been developed to register longitudinal data from all CAH children detected through neonatal screening from 2002 onwards. So far, data from 105 children have been registered (65% of Dutch CAH patients) to evaluate treatment and long-term effects in CAH.Aims: To evaluate height and weight in relation to medication used in the first 2 years of life.Methods: Biometric data and medication dosage were...

Introduction: Depending on the underlying diagnosis, Disorders of Sex Development (DSD) can be associated with an increased risk of germ cell cancers. To date, however, knowledge regarding the indications and timing of gonadectomy is lacking.Methods: The International-DSD (I-DSD) Registry was interrogated for anonymised information regarding the diagnosis, karyotype, sex of rearing and timing of gonadectomy, if undertaken, of all individuals of any karyo...

Aim: Recommendations for the management of Congenital Adrenal Hyperplasia (CAH) outline a target 17-OH Progesterone (17OHP) of 12-36nmol/l, but do not specify target concentrations for Androstenedione (D4). We aimed to study the temporal variations of these biomarkers in patients from different geographical regions.Method: This retrospective multi-centre study, including 21 centres (14 countries), analysed serum biomarke...

Aim: Recommendations for replacement glucocorticoids in CAH suggest a dose per body surface area (BSA) of glucocorticoids of 10-15mg/m2/day to maintain a 17-OH Progesterone (17OHP) level of 12-36 nmol/l across all ages. We used longitudinal analysis to assess whether biomarkers and dose of hydrocortisone varied with age in children within the I-CAH registry .Method: This retrospective multi-centre study, inclu...

Aim: The objective of the study was to determine bone mineralisation density in Turner syndrome (TS) from DSD life cohort, and to analyse the trabecular (lumbar spine = LS) and cortical bone (femoral neck = FN) mineralisation.Materials and Methods: This study was part of the DSD-LIFE study, a cross-sectional clinical outcome study of the BMD of TS adult patients from paediatric cohorts. BMD of the LS and FN were ...

Background: Association of hypothyroidism, isosexual precocious puberty and macrogonadism was first described by Van Wyk Grumbach in 1960. Van Wyk Grumbach syndrome (VWGS) was reported predominantly in females, precocious puberty and clinical picture of hypothyroidism being the clinical hallmarks.Objective and hypotheses: Publishing additional data on clinical and hormonal spectrum of VWGS, providing for better understanding of its pathology and primary ...

Introduction: The association of precocious puberty and/or polycystic ovaries, delayed bone age and hypothyroidism is known as the Van Wyk and Grumbach syndrome (VWGS). Clinically this syndrome is a diagnostic challenge because hypothyroidism usually leads to pubertal and growth delay, whereas in case of VWGS hypothyroidism it leads to growth delay and precocious puberty. We report a boy with long-standing, untreated hypothyroidism who presented with precocious puberty.<p ...

Background: Van Wyk–Grumbach syndrome (VWGS) is characterized by breast development, uterine bleeding and multi-cystic ovaries in the presence of long-lasting primary hypothyroidism.Objective and hypotheses: The pathophysiology of VWGS involves a complex mechanism, which is at least partly mediated by the direct action of TSH and FSH receptors.Method: We present a girl with Down syndrome having typical feature...
