Context. In central hypothyroidism (CeH) free thyroxine (FT4) concentrations are low while TSH concentrations may be low, normal or even slightly elevated due to reduced bioactivity. Congenital CeH (CCeH) may be isolated or part of multiple pituitary hormone deficiency (MPHD). Objective. To test our hypotheses that (1) TSH concentrations have a...

BACKGROUND: Previous cost-effectiveness studies using data from the literature showed that newborn screening for cystic fibrosis (NBSCF) is a good economic option with positive health effects and longer survival. METHODS: We used primary data to compare cost-effectiveness of four screening strategies for NBSCF, i.e. immunoreactive trypsinogen...

Background: It is generally assumed that most patients with celiac disease (CD) have a slowed growth in terms of length (or height) and weight. However, the effectiveness of slowed growth as a tool for identifying children with CD is unknown. Our aim is to study the diagnostic efficiency of several growth criteria used to detect CD children....

Measurement of development is often less precise than that of height and weight. Developmental scores are typically based on passing one or more developmental markers, but do not have interval scale so calculating differences between scores can be nonsensical. Age-specific standardized scores are sometimes used, but fail to have a common metric...

In a previous study, Dutch children with phenylketonuria (PKU) were found to be slightly shorter than their healthy counterparts. In the literature, it has been hypothesized that a higher protein intake is necessary to optimize growth in PKU patients. The study aimed to investigate whether protein intake (total, natural and protein substitute)...

Context. Since the introduction of screening for congenital hypothyroidism (CH) in 1974, the optimal laboratory strategy has been the subject of debate. Objective. To assess the clinical effectiveness and cost-effectiveness of various types of thyroxine (T4)-based strategies to screen for CH. Design, Setting, and Participants. In the Netherlands...

The goal of this study is to assess whether a growth curve model approach will lead to a more precise detection of Turner sydnrome (TS) than conventional referral criteria for growth monitoring. The Jenss-Bayley growth curve model was used to describe the process of growth over time. A new screening rule is defined on the parameters of this...

Objective: To estimate the costs and effects of different treatment strategies with intrapartum antibiotic prophylaxis to prevent early-onset group B streptococcal (GBS) disease in the Netherlands. The treatment strategies include a risk-based strategy, a screening-based strategy, a combined screening/risk-based strategy and the current Dutch...

Background/Aims: Growth monitoring is almost universally performed, but few data are available on which referral criteria and diagnostic work-up are used worldwide for children with short stature. Methods: A short questionnaire, containing questions on auxological screening and on diagnostic criteria for short stature, was sent to all members of...

Fifty-seven 7-14-year-old early- and continuously treated phenylketonuria (PKU) patients and 65 matched controls performed a sustained attention task. PKU patients with plasma phenylalanine (phe) levels higher than 360 ╬╝mol/l at the time of testing exhibited, compared to controls, lower speed of information processing, a lower ability to inhibit...

Thirty patients with early and continuously treated phenylketonuria (PKU) between 8 and 20 years of age were compared with 30 controls, matched individually for age, sex, and educational level of both parents, on behaviour rating scales for parents and teachers as well as a school achievement scale. PKU patients, as a group, demonstrated more...

In this study, we tested the hypothesis that patients with early and continuously treated phenylketonuria (PKU) are selectively impaired in cognitive functions dependent on the prefrontal cortex (PFC) over a wide age range. Thirty-six patients with PKU between 8 and 20 years of age and 36 controls matched for age, sex, and educational level of...

Objective - To assess whether physical growth is affected in early treated Dutch patients with phenylketonuria (PKU). Methods - The birth weights of all 137 early detected patients with PKU born in the period from 1974 to 1988 in the Netherlands were compared with reference values. Height, head circumference, and weight were measured at the age...

Background. The validity of the results of studies using retrospectively collected information on exposures is often criticized, because cases may report differently from controls even if their true exposure status is the same. This study was performed to quantify the extent to which this effect (differential misclassification) may occur for...

Social class and ethnicity are important risk factors for small-for-gestational-age and preterm delivery in many countries. This study was performed to assess whether this is also the case in the Netherlands, a country with a high level of social security, relatively small income differences and easy access to medical care for all its...
