Background: Prediction models demonstrate potential in predicting growth in patients receiving recombinant human growth hormone (r-hGH) for growth disorders. However, considerable information from patients is needed to calculate a predicted growth curve. The curve matching technique only requires height data. This technique identifies growth curves that are similar (matched) among real-world patients within a database. The growth curves of these ‘matched...

Poor adherence to long-term growth hormone (GH) treatment can lead to suboptimal clinical outcomes. The easypod™ connect eHealth platform enables healthcare professionals to obtain an accurate picture of real-world adherence by allowing patients to transmit adherence data to a database. Our aims were to assess adherence to r-hGH (Saizen, Merck KGaA, Darmstadt, Germany) treatment with the easypod connect platform in children from treatment start to 48 months and to investi...

Background: 46,XY patients with 5α-reductase deficiency (5-ARD), reared from birth as girls, are reported to self-reassign as boys subsequent to a masculinizing puberty; whether this holds true in cases of early orchidectomy is less well documented.Objective and hypotheses: Prepubertal orchidectomy reduces the likelihood of gender self-reassignment.Method: Presentation, management and outcome of two siblings with 5-ARD with na...

Background: Obese children come from families where either one or both parents are obese, suggesting obesity is the result of exposure to detrimental environment.Objective and hypotheses: We propose that inherited insulin resistance is the core which promotes development of obesity and that allergic airway obstruction stalls development of obesity, while peptic gastritis promotes over-eating by confounding portion control.Method: W...

Rationale: Bronchopulmonary dysplasia (BPD) is a major complication of preterm birth, which pathophysiology involves systematic inflammation. Preterm infants commonly suffer from relative adrenal insufficiency (RAI) in their first week of life, resulting in an insufficient production of cortisol inappropriate for the degree of inflammation. One of the major causes of RAI is immaturity of adrenal cortex enzymes, leading to an accumulation of cortisol precursors...

Disorders or Differences of sex development (DSD) are a heterogeneous group of congenital conditions, involving variations of chromosomal, gonadal, or anatomical development. Diagnosis is based on clinical, biochemical, imaging and genetic evaluation. In recent years knowledge about genetic causes has increased, mainly due to improved genetic techniques. In this study we investigated the yield of exome sequencing in our patients with DSD. Patients and methods: Genetic i...

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...

Background: Characterization of testicular adrenal rest tumours (TART) are one of the major long-term complications in congenital adrenal hyperplasia (CAH) patients. Although several adrenal-like properties have been assigned to these benign lesions, the exact etiology has not been established yet.Objective and Hypotheses: The aim of this study was to analyze several (steroidogenic) characteristics of TART tissue which may be classified as adrenal cortex...

Background: Subtle impairments in the thyroid function of pregnant women are associated with poorer scores on mental developmental scales in their children at age 2–3 years, and with reduced performance in a simple reaction time test at 5–6 years. However, associations with school performance estimates have never been studied.Objective and hypotheses: We aimed to assess the effect of normal variation in the maternal thyroid function during earl...

Background: Primary aldosteronism (PA) is a rare form of secondary hypertension. In adults PA is often caused by unilateral adrenal adenoma which can be cured by unilateral adrenalectomy. However, in young patients hereditary causes of PA have to be considered with bilaterally affected adrenal glands.Objective and hypotheses: We report on an adolescent with PA due to a recently described KCNJ5 mutation and want to point out the importance of performing m...
