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...

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...

Introduction: Ghrelin binds to its receptor GHSR1A, encoded by GHSR, on somatotrophs of the pituitary. Growth hormone (GH) secretion is enhanced by ghrelin binding as well as the receptor’s constitutive activity. Results from in vitro experiments, knock-out mice, and GWAS suggest that heterozygous loss-of-function of GHSR may be associated with short stature, but observations in case studies are equivocal. We aimed to better ch...

Percutaneous Epiphysiodesis Around the Knee Effectively Reduced Predicted Excessive Final Height. Preliminary Results on Final Height, Complications and Satisfaction in a Large Cohort of Dutch Boys and Girls

Goedegebuure Wesley , van der Steen Marieke , Jonkers Frank , Bakker-van Waarde Willy , Odink Roelof

Background: Percutaneous epiphysiodesis (PE) around the knee is the treatment of choice in the Netherlands to reduce predicted excessive final height. Studies until now are limited, had small numbers of patients and short follow-up periods.Objective and hypotheses: This nationwide Dutch long-term retrospective follow-up study aimed to assess final height (FH), complications and satisfaction after PE. Primary hypothesis was: ‘The PE around the knee i...

Treatment of Dyslipidemia in Children and Adolescents with Diabetes Mellitus Type 1

Borgerink M M H , van Albada M A , Venema G , Bakker-van Waarde W M

Background: Cardiovascular disease (CVD) is the major cause of mortality in diabetes mellitus type 1 (T1DM). Dyslipidemia will increase this risk. Several guidelines have been published, how to treat dyslipidemia in T1DM, yet some studies have shown that the number of patients who are treated according to these guidelines is low.Objective and hypotheses: To investigate the frequency of dyslipidemia in children and adolescents with T1DM and if they are tr...

Evaluation of Medical Treatment in the First 2 Years of Life with a New Dutch National Longitudinal Registry for Children with Congenital Adrenal Hyperplasia (CAH)

Background: Recently, a national database has been developed to register yearly data from all children detected with CAH in the neonatal screening program from 2002 onwards. So far longitudinal data of 105 children have been registered (roughly 65% of Dutch CAH patients) to evaluate medical treatment and long-term effects in CAH. A national CAH work group developed guidelines for diagnostics and follow up in CAH.Objective and hypotheses: Aim of our curre...

Metabolic Health in Short Children Born Small for Gestational Age Treated with GH and GnRHa: Results of a Randomised, Dose-response Trial

Background: Previously we showed that pubertal children born small for gestational age (SGA) with a poor adult height (AH) expectation can benefit from treatment with GH 1 mg/m2 per day (~0.033 mg/kg per day) in combination with 2 years of GnRH analogue (GnRHa) and even more so with a double GH dose. GnRHa treatment is thought to have negative effects on body composition and blood pressure. Long-term effects and GH-dose effects on metabolic health in children treate...

Identical Twins Raised as Sister and Brother

Willig Rolf Peter

Background: Disorders of sex development (DSD) can be caused by many hormonal and genetic defects. One rare condition is a mutation of the SRY-gene disturbing normal sex differentiation. Identical twins with this disorder of varying degree are presented to learn how difficult social sex assignment may be in such a case.Case presentation: Identical 46, XY twins were born in 1985 from non consanguineous, healthy parents of German origin. T...

A Case of Combined Pituitary Hormone Deficiency (CPHD) due to Anterior Pituitary Hypoplasia

Kvaratskhelia Ekaterine , Rekhviashvili Maia , Metreveli David , Willig Rolf Peter

Background: Multiple anterior pituitary hormone deficiency (MPHD) may present in the newborn period or in early infancy with hypoglycemia, prolonged cholestatic jaundice micropenis, undescended testes due to GH, ACTH, and LH deficiency. Central hypothyroidism is becoming manifest later, less severe than primary hypothyroidism, usually without intellectual impairment. A male patient was admitted to our clinic with severe short stature at the age of 2 years, born with normal len...

‘Female’, ‘Male’, or ‘Between’ in a 46, XY-Patient with a 17ß-HSD3-Mutation

Willig Rolf Peter , Algenstaedt Petra , Mohnike Klaus , Hiort Olaf

Background: 46, XY-disorders of sex development (DSD) are due to different causes like androgen insensitivity, gonadal dysgenesis, defects in testosterone metabolism and others. Exact diagnosis is mandatory prior to medical advice, therapeutic steps, or even surgical procedures. To show the difficulties of gender assignment before and also after a correct diagnosis we describe a patient who waited 35 years for the complete diagnosis, but was advised, treated and operated befor...
