Recurrent Ketosis after Prolonged Exercise in Type 1 Diabetes: The Need for Glycogen Replacement Strategies: Case Report

van Albada Mirjam , van Waarde Willie Bakker

Background: In diabetic athletes, glycogen depletion can contribute to the early development of starvation ketones as is demonstrated by our patient.Case presentation: Our patient, a 15-year-old male triathlete with type 1 diabetes for 5 years was referred to our tertiary center because of suboptimal regulation on continuous subcutaneous insulin infusion (CSII). He frequently awoke with nausea and ketosis, which was initially attributed to failure of ins...

How do I manage severe obesity

van den Akker Erica

Pediatric severe obesity is a major threat to health and longevity. Around 7% of children worldwide have early onset severe obesity before the age of 7. Pediatric obesity is caused by an interplay of multiple factors: lifestyle, environmental, sociocultural, psychological, biological and genetic factors. Endocrine, monogenetic or syndromal causes are rare, but currently underdiagnosed and important to identify for the need of specific treatment. Cardiovascular risk factors and...

Gynecological Aspects and Fertility Issues in Transgender Adolescents

Trotsenburg Mick Van

This presentation briefly gives an overview of typical gynaecological issues and fertility options of transgender adolescents.Typical gynaecological complaints and treatment options will be addressed: e.g. amenorrhea induction prior to cross-sex hormones, irregular bleeding, dysmenorrhea, vaginal discharge but also the limitations of gynaecological examination in female asssigned adolescents.National and international organizations...

Central Hypothyroidism – an Update

van Trotsenburg Paul

Central hypothyroidism can be best defined as lower than desirable thyroid hormone production and secretion because of insufficient stimulation of a normal thyroid gland by a defective pituitary or hypothalamus, resulting in a too low plasma or serum (free) thyroxine (FT4) concentration accompanied by a more or less normal thyrotropin (TSH) concentration. Central hypothyroidism can occur isolated or as part of multiple pituitary hormone deficiency and can be a congenital or ac...

Management of Central Hypothyroidism

van Trotsenburg P

Central hypothyroidism (CeH) can be defined as a lower than desirable secretion of thyroid hormone by a normal thyroid gland resulting from (quantitative or qualitative) insufficient TSH secretion. Causes are congenital and acquired functional or anatomic defects of the hypothalamus, pituitary gland or both. CeH can be difficult to diagnose, especially in children without a history of brain defects or brain damaging treatment (e.g. irradiation), and when plasma FT4 concentrati...

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 ...
