Interventions for preventing obesity in children.

BACKGROUND: The prevalence of obesity and overweight is increasing world-wide. Obesity in children impacts on their health in both the short and longer term. Obesity prevention strategies are poorly understood. OBJECTIVES: To assess the effectiveness of interventions designed to prevent obesity in childhood. SEARCH STRATEGY: Electronic databases were searched from 1985 to October 1999. SELECTION CRITERIA: Data from RCTs and non-randomised trials with concurrent control group were included. studies with follow up of one year minimum were selected, A priori, this was subsequently amended to include studies with minimum follow up of three months. The possible susceptibility of post hoc questions to bias is addressed. DATA COLLECTION AND ANALYSIS: Two reviewers independently extracted data and assessed study quality. MAIN RESULTS: Seven studies were included, three long-term and four short- term. The studies included were diverse in terms of study design and quality, target population, theoretical underpinning of intervention approach, and outcome measures. As such, it was not possible to combine study findings using statistical methods. REVIEWER'S CONCLUSIONS: The findings of the review suggest that currently there is limited quality data on the effectiveness of obesity prevention programs and as such no generalisable conclusions can be drawn. The need for well-designed studies which examine a range of interventions remains a priority.

EMS for children: recommendations for coordinating care for children with special health care needs. Emergency Medical Services for Children, National Task Force on Children With Special Health Care Needs.

STUDY OBJECTIVE: To address the need for coordinated care for children and their families during the acute care phase of their hospitalization. METHODS: A multidiscipline task force developed this concept paper through a consensus process. The process was coordinated by the Emergency Medical Services for Children Program (a program of the Health Resources and Services Administration and the National Highway Traffic Safety Administration). The task force included representatives from prehospital care, acute care, rehabilitation, primary care, and education, as well as consumers. This representation provided a broad perspective on the needs of children and their families in the transition from hospital care to home. CONCLUSION: One designated individual is essential during the acute care phase who can assist the family with gaining information and resources to ensure a successful transition to community services and resources. This article provides a framework for acute care facilities and providers to use in planning services and working with acutely ill and injured children. Several recommendations highlight the need for care coordination to be initiated early in the child's hospitalization. An overview of services and resources (both health and educational) that a child and family may need is also provided. Such services and resources include identifying a care coordinator, working with the family to identify a primary care provider before hospital discharge, and building bridges with community-based health and education services.

Corticosteroid therapy for nephrotic syndrome in children.

BACKGROUND: In nephrotic syndrome protein leaks from the blood to the urine through the glomeruli resulting in hypoproteinaemia and generalised oedema. About 70% of children experience a relapsing course with recurrent episodes of oedema and proteinuria. Children with untreated nephrotic syndrome frequently die from infections. The majority of children with nephrotic syndrome respond to corticosteroids. Corticosteroid usage has reduced the mortality rate in childhood nephrotic syndrome to around 3%, with infection remaining the most important cause of death. However corticosteroids have known adverse effects such as obesity, poor growth, hypertension, diabetes mellitus and osteoporosis. The original treatment schedules for childhood nephrotic syndrome were developed in an ad hoc manner. The optimal doses and durations of corticosteroid therapy that are most beneficial and least harmful have not been clarified. The aim of this systematic review is to assess the benefits and harms of corticosteroid therapy in treating children with nephrotic syndrome. OBJECTIVES: To determine the benefits and harms of different corticosteroid regimes in preventing relapse in children with steroid responsive nephrotic syndrome (SRNS). SEARCH STRATEGY: Published and unpublished randomised controlled trials were identified from the Cochrane Controlled Trials Register, Medline, Embase, reference lists of articles, abstracts from proceedings and contact with known investigators in the area. SELECTION CRITERIA: Randomised trials were included if they were carried out in children (aged three months to 18 years) in their initial or subsequent episode of SRNS, if they compared different durations, total doses or other dose strategies using prednisone or other corticosteroid agent and if they had outcome data at six months or more. DATA COLLECTION AND ANALYSIS: Two reviewers independently reviewed all eligible studies for inclusion, assessed study quality and extracted data. The principle outcome measure was the number of children with and without relapse after six and 12-24 months. Secondary outcomes sought included the number of children who developed frequently relapsing nephrotic syndrome and adverse events. A random effects model was used to estimate summary effect measures (relative risk RR, risk difference RD) after testing for heterogeneity. Meta-regression was used to explore potential between-study differences due to the baseline risk of relapse, study quality and types of interventions used. MAIN RESULTS: Twelve trials were identified. A meta-analysis of five trials, which compared two months of prednisone with three months or more in the first episode, showed that the longer duration significantly reduced the risk of relapse at 12 - 24 months (relative risk 0.73; 95% CI 0.60,0.89) without an increase in adverse events. There was an inverse linear relationship (RR = 1.382 (SE 0.215) - 0.133 duration (SE 0.048); r2 = 0.66; p = 0.05) between the duration of treatment and risk of relapse. The number of children who became frequent relapsers and the mean relapse rate/patient/year were also significantly reduced without increase in serious adverse events. In children with frequently relapsing nephrotic syndrome, deflazacort was significantly more effective in maintaining remission than prednisone (RR 0.44; 95% CI 0.25, 0.78). REVIEWER'S CONCLUSIONS: From this meta-analysis of randomised controlled trials it can be concluded that children in their first episode of nephrotic syndrome should be treated for at least three months with an increase in benefit being demonstrated for up to seven months of treatment. In a population with a baseline risk for relapse following the first episode of 60% with two months of prednisone, daily prednisone for four weeks followed by alternate day therapy for six months would be expected to reduce the number of children experiencing a relapse by about 40%. In children who relapse frequently, deflazacort deserves further study.

Antibiotics for preventing pneumonia in children with measles.

BACKGROUND: Measles causes more than a million deaths a year, of which most are children under five years of age who die from pneumonia. OBJECTIVES: The objective of this review was to assess the effects of antibiotics given to children with measles on reducing pneumonia or mortality, and to assess whether antibiotics should be given to all children with measles in communities with a high fatality rate. SEARCH STRATEGY: We searched MEDLINE (1966 - 1999), EMBASE (1980-1999) and the specialized trials register of the Acute Respiratory Infections Group in August 1999, and all relevant journals in the University of Melbourne medical library for the years 1935-46. SELECTION CRITERIA: Randomised or controlled trials of antibiotics for children with measles. DATA COLLECTION AND ANALYSIS: Two reviewers independently extracted data and assessed trial quality. MAIN RESULTS: Six trials with 1304 children were included. All but one of the trials were unblinded, and randomisation was either not described or was by alternate allocation. In four studies, the incidence of pneumonia in the control group was similar to that in the antibiotic prophylaxis group; in the other two studies, the incidence of pneumonia was unusually high in the control group so these children had a higher complication rate than the antibiotic group. Four of the 764 children given antibiotics died compared with one of the 637 controls. REVIEWER'S CONCLUSIONS: The quality of the trials reviewed was poor, and they provide very weak evidence for giving antibiotics to all children with measles. Available evidence suggests that antibiotics should be given only if a child has clinical signs of pneumonia or other evidence of sepsis.

Tricyclic and related drugs for nocturnal enuresis in children.

BACKGROUND: Enuresis (bedwetting) is a socially unacceptable and stressful condition which affects around 15-20% of five year olds, and up to 2% of young adults. Although there is a high rate of spontaneous remission, the social, emotional and psychological costs to the children can be great. OBJECTIVES: To assess the effects of tricyclic and related drugs on nocturnal enuresis in children, and to compare them with other interventions. SEARCH STRATEGY: The following electronic databases were searched: MEDLINE to June 1997; AMED; ASSIA; BIDS; BIOSIS Previews (1985-1996); CINAHL; DHSS Data; EMBASE (1974 to June 1997); PsycLIT and SIGLE. Organisations, manufacturers, researchers and health professionals concerned with enuresis were contacted for information. The reference sections of obtained studies were also checked for further trials. Date of the most recent search: July 1997. SELECTION CRITERIA: All randomised trials of tricyclic and related drugs for nocturnal enuresis in children were included in the review. Trials were eligible for inclusion if: children were randomised to receive tricyclics compared with placebo, other drugs or other conservative interventions for nocturnal bedwetting; participants with organic causes for their bedwetting were excluded; and baseline assessments of the level of bedwetting were provided. Trials focused solely on daytime wetting were excluded. DATA COLLECTION AND ANALYSIS: Two reviewers independently assessed the quality of the eligible trials, and extracted data. MAIN RESULTS: Twenty two randomised trials, involving 1100 children treated with tricyclic or related drugs, met the inclusion criteria. The quality of many of the trials was poor. Only single trials compared tricyclic or related drugs with each other, other drugs, desmopressin, alarms or other behavioural interventions. Treatment with tricyclic drugs (such as imipramine, amitriptyline, viloxazine, clomipramine and desipramine but not mianserin) were associated with a reduction of about one wet night per week while on treatment (eg using imipramine, WMD -0.99, 95% CI -1.27 to -0.71). Children were almost five times more likely to achieve 14 dry nights with the drugs (eg using imipramine, RR = 4.99, 95% CI 2.4 to 10.40). Desmopressin and tricyclics appeared equally effective while on treatment, but this effect was not sustained after treatment stopped. There was no detectable difference between imipramine and alarms while on treatment, but afterwards those who had used alarms had one fewer wet night per week (WMD 1.03, 95% CI 0. 19 to 1.87). REVIEWER'S CONCLUSIONS: Treatment with tricyclic drugs (imipramine, amitriptyline, viloxazine, clomipramine and desipramine but not mianserin) was associated with a reduction of about one wet night per week while on treatment, but long term effectiveness is unknown. Desmopressin and tricyclics appeared equally effective while on treatment, but this effect was not sustained after treatment stopped. Alarms may be more effective in the long term. Comparisons between drug and behavioural treatments are needed, and should include relapse rates after treatment is finished.

A comparison of the socioeconomic and health status characteristics of uninsured, state Children's health insurance program-eligible children in the united states with those of other groups of insured children: implications for policy.

OBJECTIVES: To describe the sociodemographic and health status characteristics of the national uninsured, State Children's Health Insurance Program (SCHIP)-eligible population, and to compare this population with Medicaid-enrolled children, privately insured children, and privately insured children who have family income in the SCHIP eligibility range. PROCEDURES: Data were analyzed for 50 950 children 0 to 18 years of age included in the 1993 and 1994 National Health Interview Surveys. The survey obtained information on insurance coverage and sociodemographic and health status measures. Bivariate analyses were conducted to identify the relationships between SCHIP eligibility and sociodemographic and health status characteristics. Multivariate analyses were conducted to assess the independent association of the sociodemographic and health status variables with the likelihood of being uninsured, SCHIP-eligible. PRIMARY FINDINGS: Results indicate that SCHIP children exhibit markedly different socioeconomic and health status characteristics than do both Medicaid- enrolled and privately insured children, although these differences are less significant in privately insured children. SCHIP children more often live with college- educated (39.4%) and employed adults (91.2%) than do Medicaid-enrolled children (23.0% and 53.9%, respectively). However, SCHIP children live with college-educated and employed adults less than do all privately insured children (66.7% and 96.9%, respectively) and privately insured/same-income children (57.8% and 97.0%, respectively). Parents of SCHIP-eligible children are also disproportionately self-employed or employed in industries (e.g., retail trade) and occupations in which health insurance coverage is less available or affordable. SCHIP-eligible children are also 2 times more likely to be adolescents and 11/2 times more likely to be in excellent health than Medicaid-eligible children. Compared with privately insured children, SCHIP-eligible children are nearly 3 times more likely to be Hispanic and nearly 2 times more likely to be rated in fair or poor health. CONCLUSIONS: The results demonstrate that uninsured, SCHIP-eligible children are substantially different from children in these groups, particularly compared with Medicaid-enrolled children. These differences need to be taken into account when setting policies and implementing programs intended to increase health insurance coverage and access to health care.

[Body composition in overweight children, healthy children as well as children with mucoviscidosis, measured by multifrequency impedance].

The body composition of a total of 90 children (aged 5-18) were subjected to multifrequency impedance measurement with a Human IM Scan impedance analyser. We compared data of 30 overweight children (17 boys, 13 girls; mean age 11.47 yrs, range: 4-17 yrs), 30 children with cystic fibrosis (12 boys, 18 girls; mean age 12.8 yrs, range: 3-24 yrs) and 30 healthy children (12 boys, 18 girls; mean age 13.4 yrs, range 7-18 yrs). The percentage of fat mass was found to be inversely proportional to total body water. Extracellular water expressed as a percentage of the total body water was significantly higher in overweight children than in the other two groups: (p < 0.01) between children with cystic fibrosis and overweight children, (p < 0.05) between healthy children and overweight children. Extracellular water expressed as a percentage of total body water was lower in children with cystic fibrosis than in healthy children (p < 0.05). The ratios of extracellular mass and body cell mass to body weight were significantly lower in overweight children than in healthy children (p < 0.01) or in children with cystic fibrosis (p < 0.01). The ratio of exchangeable sodium and potassium was lower in all three groups than the normal value given for adults (> 0.87), but in overweight children it was significantly higher than in the other two groups; (p < 0.01) between children with cystic fibrosis and overweight children, (p < 0.05) between healthy children and overweight children. Multifrequency impedance measurement is reliable, fast, non-invasive, easy to carry out, therefore we consider it very useful in determining the body composition of children in various pathological conditions.

MRI findings of the pituitary gland in short children born small for gestational age (SGA) in comparison with growth hormone-deficient (GHD) children and children with normal stature.

BACKGROUND: Disturbances in the GH/IGF-I axis are reported in 25-60% of short children born small for gestational age (SGA). We hypothesized that these abnormalities might be related to abnormalities in the pituitary region. Therefore, the results of magnetic resonance imaging (MRI) of short SGA children were compared to MRI results of other groups of short children and to normal controls. PATIENTS AND METHODS: MRI was performed in four groups of short children: SGA children without GH deficiency (SGA group; n = 17), SGA children with isolated GH deficiency (SGA + IGHD group; n = 10), non-SGA children with isolated GH deficiency (IGHD group; n = 24) and non-SGA children with multiple pituitary hormone deficiencies (MPHD group; n = 15). MRI was also performed in children with normal stature (control group; n = 13). Pituitary height (PH) and thickness of the pituitary stalk (PS) were measured and their relationship with the maximum GH peak during a GH stimulation test, serum IGF-I and IGFBP-3 levels was evaluated. RESULTS: Short SGA children either with or without IGHD did not show major anatomical abnormalities in the hypothalamic-pituitary region in contrast to 58% of the non-SGA IGHD children and 87% of the MPHD children who had anatomical abnormalities. PH in SGA children without GHD was normal whereas it was significantly lower in SGA children with IGHD. The lowest PHs were measured in non-SGA children with MPHD. A moderate decrease in PH was associated with significantly lower maximum serum GH peaks and lower serum IGF-I and IGFBP-3 levels. CONCLUSION: Measuring PHs in children with less severe GHD, who underwent MRI as part of the diagnostic process, might support the diagnosis of GHD even in the absence of anatomical abnormalities. Our study demonstrates that there is no indication to perform MRI of the pituitary region in short children born SGA without GHD.

Assessing candidate children for cochlear implantation with the Nottingham Children's Implant Profile (NChIP): the first 200 children.

BACKGROUND/OBJECTIVE: Nottingham Children's Implant Profile (NChIP) is a profile designed to assess candidate children for cochlear implantation. It includes the demographic details of the children (chronological age and duration of deafness), medical and radiological conditions, the outcomes of audiological assessments, language and speech abilities, multiple handicaps or disabilities, family structure and support, educational environment, the availability of support services, expectations of the family and deaf child, cognitive abilities, and learning style. The aim of the present study is to present the NChIP data obtained on the first 200 children implanted in the same cochlear implant programme and evaluate NChIP's use in the selection phase of cochlear implantation. PATIENTS: The study assessed 200 profoundly deaf children. Fifty-six children (28%) were deafened by meningitis, 132 (66%) were born deaf, and 12 (6%) were deafened from other causes (head injury, viral infection, progressive deafness). RESULTS: Chronological age at the time of assessment (before implantation) was the most common factor of major concern (9% of the children studied) and the pre-implant language and speech abilities of the children was the most common factor of mild to moderate concern, affecting 63% of the children. The second most common factor of mild to moderate concern was duration of deafness (37%) and the third was the learning style of the children (33%). Availability of support services was the least factor of concern as 179 children (90%) did not have any problems in this area. CONCLUSIONS: Earlier identification of deafness (by universal neonatal hearing screening programs) may reduce age at implantation and duration of deafness as areas of concern in the future. However, the pre-implant language and speech abilities of the candidate children, the gap between chronological and language age, and the learning style of children are now emerging as key areas of research in the field. NChIP was found to be a very useful casework tool in the initial evaluation of the deaf children promoting and enhancing interdisciplinary teamwork across the different professionals. NChIP was also used as part of the decision-making process by the cochlear implant programme professionals and as a counselling tool for the parents. Finally, NChIP has helped to identify those children and families who need additional support. In the case of recently established paediatric cochlear implant programmes it would be a 'neutral' yet sensitive way of promoting good interdisciplinary collaboration and also peer support within team discussions when selecting children for cochlear implantation.

Group-based parent-training programmes for improving emotional and behavioural adjustment in 0-3 year old children.

BACKGROUND: Mental health problems in children are common. Research suggests that parenting has an important role to play in helping children to become well adjusted adults, and that the first few months and years of a child's life are especially important in establishing patterns of emotional, cognitive and social functioning which will in turn influence the child's future development and in particular, their mental health. Parenting programmes may therefore have a role to play in improving the mental health of infants and toddlers. OBJECTIVES: The objectives of this review are as follows: a) To establish whether group-based parenting programmes are effective in improving the mental health of children less than three years of age b) To assess the role of parenting programmes in the primary prevention of mental health problems SEARCH STRATEGY: A range of biomedical and social science databases were searched including MEDLINE, EMBASE, CINAHL, PsychLIT, Sociofile, Social Science Citation Index, ASSIA, the Cochrane Library including SPECTR, CENTRAL, National Research Register (NRR) and ERIC. SELECTION CRITERIA: Only randomised controlled trials were included and studies had to include at least one standardised instrument measuring some aspect of infant mental health. DATA COLLECTION AND ANALYSIS: The treatment effect for each outcome in each study was standardised by dividing the mean difference in post-intervention scores for the intervention and treatment group, by the pooled standard deviation, to obtain an effect size. The results for each outcome in each study have been presented with 95% confidence intervals. Where appropriate the results have been combined in a meta-analysis using a random effect model. MAIN RESULTS: A total of five studies were included in the review. The 5 included studies provided a total of 36 assessments of infant and toddler mental health including emotional and behavioural adjustment, and sleep patterns. All of the results apart from 6 showed positive findings favouring the intervention group. While some of findings were non-significant, most of the effect sizes were large and the wide confidence intervals crossing the zero that were obtained in a number of the studies, were very probably due to small sample sizes. There was sufficient data from four studies to combine the results in a meta-analysis. The results of the meta-analysis show a significant difference in children's emotional and behavioural adjustment favouring the intervention group. Overall, the limited follow-up data provide equivocal evidence concerning the maintenance of these effects over time. REVIEWER'S CONCLUSIONS: The results of this review suggest that parenting programmes can be effective in improving the mental health of infants and toddlers. There is, however, insufficient evidence to reach any firm conclusions regarding the role that such programmes might play in the primary prevention of mental health problems. Furthermore, there is insufficient evidence to know whether the short-term benefit of these programmes is maintained over time, and further research is required.

TT virus infection in healthy children, children after blood transfusion, and children with non-A to E hepatitis or other liver diseases in Taiwan.

Serum samples from healthy and diseased children were studied for the presence of TTV DNA by nested PCR using primer sets generated from N-22 region and from the untranslated region (UTR) of the viral genome. N-22 positive TTV DNA was detectable in 33 (27%) of 122 healthy children, 47 (73.4%) of 64 polytransfused thalassemic children, 37 (46.3%) of 80 children who received transfusion during cardiac surgery, 8 (42.1%) of 19 non-A to E hepatitis, 10 (33.3%) of 30 HBV carrier children, and 5 (15.6%) of 32 infants with biliary atresia. A much higher prevalence of TTV DNA with rates varying from 78-100% in the above study groups was observed using the UTR primers. For children with N-22 positive TTV DNA, biochemical assessment of isolated TTV viremia in thalassemic children or children transfused during surgery showed no convincing association between raised ALT levels and TTV viremia. Coinfection with TTV in chronic HCV-infected or HBV-infected children did not result in higher peak ALT levels during follow-up, suggesting that TTV has no synergistic pathogenic effect. The phylogenetic analysis of the N-22 positive TTV DNA isolates revealed that most isolates from healthy children, children transfused during surgery, and non-A to E fulminant hepatitis children were type 1 TTV. These results indicate that TTV infection in children was significantly associated with transfusion. TTV infection is highly prevalent in early childhood in Taiwan but plays a minimal role in the induction of hepatitis in children.

Inhibition of OM pathogens by alpha-hemolytic streptococci from healthy children, children with SOM and children with rAOM.

The present study was undertaken to elucidate the inhibitory activity of the normal nasopharyngeal flora against the three most common otitis media (OM) pathogens in healthy children, children with secretory otitis media (SOM) and children with recurrent otitis media (rAOM). Isolates of alpha-hemolytic streptococci (AHS) and OM pathogens were recovered from the tubal orifice in each child. The samples were taken from 20 healthy children under general anesthesia, from 19 children with SOM and 20 children with rAOM. The method used to test the bacterial interference in vitro was a modified agar overlay method. The AHS sampled from the tubal orifice of the healthy children were able to inhibit 92% of the S. peumoniae isolates, 74% of the non-typable H. influenzae isolates and 89% of the M. catarrhalis isolates. The corresponding figures for children with SOM and children with rAOM were: 73% of the S. pneumoniae isolates, 58 and 54% of the non-typable H. influenzae isolates and 86 and 89% of the M. catarrhalis isolates. The AHS from children with SOM and children with rAOM were significantly less capable of inhibiting the S. peumoniae and the H. influenzae isolates (P<0.001). There was no significant difference between the three groups of children regarding inhibitory activity against M. catarrhalis. The results suggest that the inhibitory activity of the normal bacterial flora at the tubal orifice against pneumococci and H. influenzae may be reduced in children with SOM and rAOM.

Short-term follow-up of children at risk: comparison of the quality of life of children removed from home and children remaining at home.

OBJECTIVE: To follow up the well-being of children at risk after a decision on their removal was made. METHOD: Social workers assessed the quality of life (QOL) of three groups of children (n = 92): children they had decided to keep at home, children whom they had removed to alternative care, and children who remained at home despite the decision to remove them. This is a prospective study, in which assessments were made at two points of time: first when the workers began to consider whether or not to remove the child, and again 6 months later. RESULTS: The findings show that even though the QOL of the children in the three groups was similarly low at the first measure, it differed in the second. The QOL of the children who were removed from home had improved, that of the children who remained at home in accord with the workers' decisions remained roughly the same, and that of the children for whom the decision to remove was not implemented declined. CONCLUSION: The findings suggest that children at risk may fare better in terms of QOL in alternative placement than at home, and highlight the high price paid by children for whom a decision to remove them from home is not implemented. Further research, however, is required, taking into consideration the interventions and services that the children and their families received in the different settings.

Word recognition by children listening to speech processed into a small number of channels: data from normal-hearing children and children with cochlear implants.

OBJECTIVE: The aims of this study were 1) to determine the number of channels of stimulation needed by normal-hearing adults and children to achieve a high level of word recognition and 2) to compare the performance of normal-hearing children and adults listening to speech processed into 6 to 20 channels of stimulation with the performance of children who use the Nucleus 22 cochlear implant. DESIGN: In Experiment 1, the words from the Multisyllabic Lexical Neighborhood Test (MLNT) were processed into 6 to 20 channels and output as the sum of sine waves at the center frequency of the analysis bands. The signals were presented to normal-hearing adults and children for identification. In Experiment 2, the wideband recordings of the MLNT words were presented to early-implanted and late-implanted children who used the Nucleus 22 cochlear implant. RESULTS: Experiment 1: Normal-hearing children needed more channels of stimulation than adults to recognize words. Ten channels allowed 99% correct word recognition for adults; 12 channels allowed 92% correct word recognition for children. Experiment 2: The average level of intelligibility for both early- and late-implanted children was equivalent to that found for normal-hearing adults listening to four to six channels of stimulation. The best intelligibility for implanted children was equivalent to that found for normal-hearing adults listening to six channels of stimulation. The distribution of scores for early- and late-implanted children differed. Nineteen percent of the late-implanted children achieved scores below that allowed by a 6-channel processor. None of the early-implanted children fell into this category. CONCLUSIONS: The average implanted child must deal with a signal that is significantly degraded. This is likely to prolong the period of language acquisition. The period could be significantly shortened if implants were able to deliver at least eight functional channels of stimulation. Twelve functional channels of stimulation would provide signals near the intelligibility of wideband signals in quiet.

Bacterial and fungal components in house dust of farm children, Rudolf Steiner school children and reference children--the PARSIFAL Study.

BACKGROUND: Growing up on a farm and an anthroposophic lifestyle are associated with a lower prevalence of allergic diseases in childhood. It has been suggested that the enhanced exposure to endotoxin is an important protective factor of farm environments. Little is known about exposure to other microbial components on farms and exposure in anthroposophic families. OBJECTIVE: To assess the levels and determinants of bacterial endotoxin, mould beta(1,3)-glucans and fungal extracellular polysaccharides (EPS) in house dust of farm children, Steiner school children and reference children. METHODS: Mattress and living room dust was collected in the homes of 229 farm children, 122 Steiner children and 60 and 67 of their respective reference children in five European countries. Stable dust was collected as well. All samples were analysed in one central laboratory. Determinants were assessed by questionnaire. RESULTS: Levels of endotoxin, EPS and glucans per gram of house dust in farm homes were 1.2- to 3.2-fold higher than levels in reference homes. For Steiner children, 1.1- to 1.6-fold higher levels were observed compared with their reference children. These differences were consistently found across countries, although mean levels varied considerably. Differences between groups and between countries were also significant after adjustment for home and family characteristics. CONCLUSION: Farm children are not only consistently exposed to higher levels of endotoxin, but also to higher levels of mould components. Steiner school children may also be exposed to higher levels of microbial agents, but differences with reference children are much less pronounced than for farm children. Further analyses are, however, required to assess the association between exposure to these various microbial agents and allergic and airway diseases in the PARSIFAL population.

How Medicaid and the State Children's Health Insurance Program can do a better job of insuring uninsured children: the perspectives of parents of uninsured Latino children.

BACKGROUND: Eight and a half million US children are uninsured, despite the 1997 enactment of the State Children's Health Insurance Program (SCHIP) with $39 billion in funding, and Latinos continue to be the most uninsured racial/ ethnic group, with 24% (3 million) uninsured. Why SCHIP and Medicaid have not been more successful insuring uninsured children is unclear. OBJECTIVE: To identify reasons why parents are unable to insure uninsured Latino children in a state where all low-income children are eligible for insurance. METHODS: Bilingual focus groups of parents of uninsured Latino children from Boston communities with the highest proportion of uninsured Latino children. RESULTS: The 30 parents interviewed in 6 focus groups had a mean age of 39 years; 63% never graduated high school and 33% were US citizens. The mean age of their children was 12 years, and the median annual family income was $9120. Parents reported 52 barriers to insuring children. Major obstacles included lack of knowledge about the application process and eligibility (especially misconceptions about work, welfare, and immigration), language barriers, immigration issues, income, hassles, pending decisions, family mobility, misinformation from insurance representatives (being told insurance is too expensive and parents must work), and system problems (including lost applications, discrimination, and excessive waits). Parents universally agreed case managers would be helpful in insuring uninsured children. CONCLUSIONS: Even in a state where all low-income children are eligible for health insurance, current SCHIP and Medicaid outreach and enrollment are not effectively reaching uninsured Latino children. Parents need better information about programs, eligibility, and the application process, and a more efficient, user-friendly system.

Can the Children's Communication Checklist differentiate between children with autism, children with ADHD, and normal controls?

BACKGROUND: The Children's Communication Checklist (CCC; Bishop, 1998) is a questionnaire that was developed to measure pragmatic language use and may be completed by parents and teachers. Two studies are reported, which were designed to investigate: (1) whether children with Attention Deficit Hyperactivity Disorder (ADHD) encounter pragmatic language problems in comparison with normal controls (NC), (2) whether children with ADHD and children with High Functioning Autism (HFA) can be differentiated using the CCC, (3) the usefulness of the CCC for parents and teachers in a clinical and in a research setting, and (4) the role of age in pragmatic language use in ADHD and HFA. METHOD: In the first study (clinical sample) 50 children with ADHD, 50 children with HFA, and 50 NC were compared to each other using the CCC. In the second study (research sample) CCC data was gathered on 23 children with ADHD (without co-morbid disorders), 42 children with HFA, and 35 NC. RESULTS: Compared to NC, children with HFA showed pragmatic deficits on all CCC scales. Children with ADHD demonstrated deficits compared to NC as well. Moreover, the ADHD and HFA groups differed from each other on most of the scales. Discriminant analyses showed that CCC scales were relevant for case identification in these samples. Furthermore, profiles of impairment seen in children with HFA and ADHD did not vary with age. CONCLUSION: Pragmatic difficulties do occur in both HFA and ADHD. The present studies indicate that the CCC is a useful instrument to obtain information concerning pragmatic language use in both a clinical and a research setting. Although the information of parents is more tightly linked to the diagnosis, combining the information of both parent and teacher slightly improves case identification.

Theory of mind abilities of children with schizophrenia, children with autism, and normally developing children.

Theory of mind (ToM) abilities of children with schizophrenia, children with high functioning autism, and normally developing children, matched on mental age (MA), verbal MA, and performance MA, were compared. Both clinical groups were matched on chronological age as well, whereas the normally developing children were younger. A fact belief task, a value belief task, a deception task, and a false belief task were administered. The three groups did not differ on the fact belief task. Children with autism performed more poorly than normally developing children on value belief and false belief tasks, and more poorly than individuals with schizophrenia on the deception task. Children with schizophrenia performed more poorly than normally developing children only on the false belief task. Overall, the group with autism passed significantly fewer tasks compared to the normally developing group. ToM abilities correlated with verbal abilities for individuals with autism. The ToM abilities of children with paranoid schizophrenia and children with undifferentiated or disorganized schizophrenia did not differ. Findings strengthen the notion of a limited understanding of ToM in schizophrenia, and support the notion that ToM deficits, although more severe in autism, are not unique to autism.
