[Time to collaborate? Experiences of paediatricians cooperating with child and adolescent psychiatry]. / Samen beter? Kinderartsen over samen-werking met kinder- en jeugdpsychiatrie.

BACKGROUND: Pediatricians and child and adolescent psychiatrists share patient populations. However, the availability of child and adolescent psychiatric care in Dutch hospitals is often limited. AIM: To inventorize the experiences and wishes of Dutch pediatricians with regard to collaboration between pediatrics and child and adolescent psychiatry, especially in the St. Antonius Hospital where consultation has been started. METHOD: Online survey among pediatricians in 16 hospitals in the Netherlands and qualitative interviews with pediatricians and medical psychologists in the St. Antonius Hospital. RESULTS: Interview attendees experienced obstacles in waiting lists, organization of care, and limited options for immediate consultation. The majority experienced that child and adolescent psychiatric care was insufficient in their hospitals. CONCLUSION: Extending consultative collaboration could improve the care for children and reduce some of the obstacles experienced by the participants of this study. Consultation contributes to quality of care in hospitals and encourages collaboration.

Bone mineral density in children and adolescents with Prader-Willi syndrome: a longitudinal study during puberty and 9 years of growth hormone treatment.

CONTEXT: Longitudinal data on bone mineral density (BMD) in children and adolescents with Prader-Willi Syndrome (PWS) during long-term GH treatment are not available. OBJECTIVE: This study aimed to determine effects of long-term GH treatment and puberty on BMD of total body (BMDTB), lumbar spine (BMDLS), and bone mineral apparent density of the lumbar spine (BMADLS) in children with PWS. DESIGN AND SETTING: This was a prospective longitudinal study of a Dutch PWS cohort. PARTICIPANTS: Seventy-seven children with PWS who remained prepubertal during GH treatment for 4 years and 64 children with PWS who received GH treatment for 9 years participated in the study. INTERVENTION: The children received GH treatment, 1 mg/m(2)/day (≅ 0.035 mg/kg/d). MAIN OUTCOME MEASURES: BMDTB, BMDLS, and BMADLS was measured by using the same dual-energy x-ray absorptiometry machine for all annual measurements. RESULTS: In the prepubertal group, BMDTB standard deviation score (SDS) and BMDLSSDS significantly increased during 4 years of GH treatment whereas BMADLSSDS remained stable. During adolescence, BMDTBSDS and BMADLSSDS decreased significantly, in girls from the age of 11 years and in boys from the ages of 14 and 16 years, respectively, but all BMD parameters remained within the normal range. Higher Tanner stages tended to be associated with lower BMDTBSDS (P = .083) and a significantly lower BMADLSSDS (P = .016). After 9 years of GH treatment, lean body mass SDS was the most powerful predictor of BMDTBSDS and BMDLSSDS in adolescents with PWS. CONCLUSIONS: This long-term GH study demonstrates that BMDTB, BMDLS, and BMADLS remain stable in prepubertal children with PWS but decreases during adolescence, parallel to incomplete pubertal development. Based on our findings, clinicians should start sex hormone therapy from the age of 11 years in girls and 14 years in boys unless there is a normal progression of puberty.

Eight years of growth hormone treatment in children with Prader-Willi syndrome: maintaining the positive effects.

BACKGROUND: The most important reason for treating children with Prader-Willi syndrome (PWS) with GH is to optimize their body composition. OBJECTIVES: The aim of this ongoing study was to determine whether long-term GH treatment can counteract the clinical course of increasing obesity in PWS by maintaining the improved body composition brought during early treatment. SETTING: This was a multicenter prospective cohort study. METHODS: We have been following 60 prepubertal children for 8 years of continuous GH treatment (1 mg/m(2)/d ≈ 0.035 mg/kg/d) and used the same dual-energy x-ray absorptiometry machine for annual measurements of lean body mass and percent fat. RESULTS: After a significant increase during the first year of GH treatment (P < .0001), lean body mass remained stable for 7 years at a level above baseline (P < .0001). After a significant decrease in the first year, percent fat SD score (SDS) and body mass index SDS remained stable at a level not significantly higher than at baseline (P = .06, P = .14, resp.). However, body mass index SDSPWS was significantly lower after 8 years of GH treatment than at baseline (P < .0001). After 8 years of treatment, height SDS and head circumference SDS had completely normalized. IGF-1 SDS increased to +2.36 SDS during the first year of treatment (P < .0001) and remained stable since then. GH treatment did not adversely affect glucose homeostasis, serum lipids, blood pressure, and bone maturation. CONCLUSION: This 8-year study demonstrates that GH treatment is a potent force for counteracting the clinical course of obesity in children with PWS.

Assessment of the relationship between joint laxity and migration of the hip in children with Down syndrome.

PURPOSE: The aim of this cross-sectional cohort study is to describe the incidence of joint laxity and the correlation between joint laxity and radiological migration of the hip in children with Down syndrome. METHODS: Sixty-five children (2-19 years) with Down's syndrome were examined for joint laxity. For each subject, laxity scores for joints were carried out with the Bulbena method. Plane pelvic radiographs were used to determine the migration of the hip, according to Reimer's migration index. RESULTS: In this study, 26 out of 65 children with Down's syndrome (40 %) were diagnosed with general joint laxity. On the radiographs of the hips we found a mean Reimer's Migration Index of 5.2 % for all the subjects. Children with general joint laxity showed a lower Reimer's Migration Index (2.1 %). No significant correlation was found between general joint laxity and migration of the hip. CONCLUSIONS: This study showed no relationship between joint laxity and migration of the hip in children with Down's syndrome. This implicates that we were not able to prove that joint laxity is the major factor in developing hip migration in children with Down's syndrome.

Enterobacter colonisation in newborn infants: predictors, follow-up and implications for infection control.

Outbreaks with Enterobacter spp. have been described frequently in neonatal intensive care units (NICUs). This study investigated the factors that determine whether a neonate becomes colonised with Enterobacter spp., how long colonisation continues and whether the termination of isolation measures leads to spread of the organism. Neonates transferred from the NICUs of tertiary care hospitals were screened for the presence of Enterobacter spp. and any potential predictors for colonisation recorded. Those infected were monitored during their hospital stay and colonised neonates were screened every month for six months. Isolation infection control precautions were lifted and all neonates were screened for the presence of Enterobacter spp. six and 12 months later. Fifteen colonised neonates and 33 non-colonised controls were identified for study. Multivariate analysis showed that antibiotic therapy for more than three days and an Apgar score of <8 after 1 min were independently associated with Enterobacter spp. colonisation. Molecular typing using single-enzyme amplified-fragment length polymorphism (seAFLP) analysis revealed 22 different seAFLP genotypes. Three infants remained colonised with the same Enterobacter genotype after discharge; however, most neonates lost their strain or became colonised with another genotype. Lifting infection control measures for neonates colonised with Enterobacter spp. in a neonatal ward did not lead to increased incidence of colonisation and none of the infants became infected. Isolating neonates with susceptible Enterobacter spp. was not found to be necessary.

Diagnosis of enterovirus infection in the first 2 months of life by real-time polymerase chain reaction.

During summer and fall, enterovirus infections are responsible for a considerable proportion of hospitalizations of young infants. We prospectively studied the incidence of enterovirus infections via real-time polymerase chain reaction (PCR) in blood, feces, and cerebrospinal fluid samples from infants

Treatment of defecation disorders by colonic enemas in children with spina bifida.

Faecal incontinence and constipation are well known problems in children with spina bifida. Effective treatment can be difficult and this gave the condition a low priority despite the obvious physical and psychological sequelae. Positive experience with colonic enemas (CE) in the paediatric post-operative care have led us to adopt this method as the treatment of choice for defecation disorders in children with spina bifida. In 41 spina bifida children (mean age 8.4 years, range 7 months to 22 years), retrograde CEs with hand-warm tap water were given at home from once a day to twice per week. Satisfaction with the procedure was evaluated with a questionnaire sent out after a mean follow-up period of 33 months (range 6 to 55 months). The indications to start CEs were faecal incontinence (27%), constipation (27%) or both. 34% of 41 children also had other gastrointestinal complaints, 7% had headaches, 29% had poor appetite and 15% felt generally unwell. Before the start of CE 22% of the children had been on a diet, 37% on oral laxatives, 31% on a rectal laxative and 44% had to have manual evacuations. 90% used diapers on a daily basis. At the end of the follow-up period 27% of the children were still on a diet and 17% still used oral laxatives but rectal laxatives were no longer used nor were manual evacuations necessary. 66% of the 41 children were completely faecally continent and constipation occurred only occasionally, no child had faecal retention or impaction. At follow-up 39% still used diapers regularly and 20% used a panty-line and complaints of abdominal pain, headache and poor appetite were rare. Satisfaction with the procedure was rated highly by 63% of parents and children and good by 37% but 15% of the children found regular CEs painful. It is concluded from the study that CEs are therapeutically effective in the treatment of both faecal incontinence and constipation in children with spina bifida. The procedure is well tolerated even by very young children. Long-term histopathological effects of daily CEs on the lower gastrointestinal tract needs to be evaluated by future research.
