Motor Performance in Turner Syndrome

van Alfen Janielle

The aim of this presentation is to give an overview of motor disabilities in girls with Turner syndrome (TS), the impact on daily life and suggestions for treatment.Girls with TS show substantially lower performance in gross and fine motor function tests and motor milestones are achieved relatively late. Moreover, girls with TS frequently encounter problems in specific motor functioning i.e. oral-motor and visual-motor coordination, motor learning and pr...

Testicular Adrenal Rest Tumors (TARTs) as presenting symptom of CAH due to CYP11A1deficiency.

Bakker-van Waarde Willie , Claahsen-van der Grinten Hedi

Background: TARTs mostly occur in congenital adrenal hyperplasia due to 21-hydroxylase deficiency, but were described in other forms of CAH. Elevated ACTH levels, may play a role in TARTs development. Here we describe the first child with undetected CYP11A1 deficiency who presented with TART.Case description: An 11 year old boy noticed left sided scrotal enlargement, without further complaints. Ultrasound showed a hydroc...

How to Recognize Underlying Somatic Causes of Paediatric Obesity? Performance of the Diagnostic Recommendations of the Endocrine Society Guideline and Suggestions for Improvement

Abawi Ozair , Kleinendorst Lotte , van der Voorn Bibian , Brandsma Annelies , van Rossum Elisabeth , van Haelst Mieke , van den Akker Erica

Background: Underlying causes of obesity are thought to be rare even in specialized paediatric endocrinology clinics. However, evidence is limited. The Endocrine Society (ES) guideline for paediatric obesity makes the following diagnostic recommendations: endocrine evaluation in presence of reduced growth velocity, evaluation of cerebral obesity in presence of CNS injury, re-evaluation of drug choice in patients using antipsychotics. Genetic testing is recomme...

Gonadal Function in Congenital Adrenal Hyperplasia (CAH)

Claahsen - van der Grinten Hedi

Congenital adrenal hyperplasia (CAH) is a group of rare congenital disorders of the adrenal cortex due to a defect in one of the enzymes involved in steroid synthesis leading to cortisol deficiency and overproduction of adrenal androgens. In the most severe forms CAH is a life threatening disease due to the risk of Addisonian and salt wasting crisis. In the last 50 years diagnostics and treatment improved significantly. Patients are treated with lifelong replacement of glucoco...

Homozygous Mutation in FBN1 Gene In-Patient with Prader–Willi Syndrome: Variant Marfan Syndrome?

van den Boom-Rijk Yvonne , Kempers Marlies , van der Sanden Ria Nijhuis , van Alfen-van der Velden Janielle

Background: Prader–Willi syndrome (PWS) is caused by absence of expression of imprinted genes on the paternal chromosome 15 (15q11.2–q13) due to a paternal deletion, maternal uniparental disomy 15 and rarely an imprinting defect. The clinical signs of PWS are hypotonia, muscle weakness, excessive eating, morbid obesity, delayed global development, hypogonadism, and short stature. Marfan syndrome is caused by mutations in the FBN1 gene, located on chromosome ...

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: 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...

Tall Stature and Macrodactyly of the Great Toes Due to a Novel Mutation in the Natriuretic Peptide Receptor-2 Gene

Lauffer Peter , van Duyvenvoorde Hemine , van Haeringen Arie , van der Kaay Danielle

Background: Mutations in the gene encoding the natriuretic peptide receptor-2 gene (NPR2) are responsible for monogenic growth disorders. Loss-of-function variants cause extreme short stature and skeletal dysplasia. Gain-of-function mutations cause tall stature with - in some cases - macrodactyly of the great toes, a Marfanoid habitus, arachnodactyly and scoliosis. We describe a novel gain-of-function mutation in exon 8 of NPR2 in a family wi...

Personalized Health Care: Home POCT Sodium Measurement in Diabetes Insipidus Centralis in a Patient with Impaired Thirst Perception

van der Linde Annelieke , van Herwaarden Teun , de Grouw Elke , Claahsen - van der Grinten Hedi

Background: Central diabetes insipidus (CDI) is caused by deficiency of antidiuretic hormone (ADH). Patients with CDI are at risk for fluid balance disturbances, especially when there is impaired thirst perception or inability to access water freely. Serum sodium measurement gives a good reflection of the actual fluid balance but is generally not available in the home situation. For patients in which CDI is difficult to manage sodium measurement at home may be a good instrumen...
