School refusal in children and adolescents: a review of the past 10 years.

OBJECTIVE: To critically review the past 10 years of research on school refusal in children and adolescents. METHOD: Literature on school refusal published from 1990 onward was reviewed following a systematic search of PsycINFO. The review focuses on definitional issues, epidemiology and school refusal identification, diagnostic considerations, family functioning, assessment, treatment, and follow-up studies. RESULTS: While definitional and conceptual issues are still evident, promising developments have occurred in relation to assessment and treatment practices and understanding of the family context of school refusal. CONCLUSIONS: From a clinical viewpoint, school refusal cases require comprehensive assessment and treatment. Advances have been made in the treatment of school refusal. However, additional controlled studies evaluating interventions for school refusal are needed.

Characteristics of maltreatment experience and academic functioning among maltreated children.

This article examined the impact of maltreatment characteristics on academic functioning in a sample of school-age maltreated children. Results revealed several differences among three types of maltreatment subgroups (physical abuse, neglect, and sexual abuse) on characteristics of maltreatment experience. Few maltreatment characteristics were significantly related to measures of academic functioning, but the findings suggest that the effects of maltreatment characteristics should be examined separately for different types of maltreatment.

Respiratory morbidity and lung function after whooping-cough.

360 primary-school children with a history of whooping-cough were shown to have experienced an excess of other chest illnesses compared with 711 controls. This susceptibility may, however, have antedated the whooping-cough. Current respiratory symptoms were also more common in children who had had whooping-cough, though no differences were found on physical examination. No differences were found in lung function between cases and controls. Whooping-cough, as experienced by British children in recent years, is unlikely to cause subsequent respiratory morbidity and does not result in impaired lung function in later childhood.

Child competence and psychiatric risk. II. Areas of relationship between child and family functioning.

Teacher and peer ratings of 65 children at risk to schizophrenia and other severe psychopathology were divided into three behavioral domains: problem solving, social-emotional, and compliance. Each child area was then related to variables generated from a family consensus Rorschach procedure in an effort to gain a greater understanding of the mechanism of risk involvement. Within the problem solving domain, parental communication deviance, nonacknowledgment of comments, and clear communication were the three family variables which consistently and linearly related to child competence at school. In the social-emotional area, only parental communication deviance displayed a linear relationship to the child's functioning at school. No significant findings occurred in the area of compliance behavior, and the roles of age of child and child IQ did not influence any of the findings. The data indicated that parental communication deviance may be an important variable in risk involvement.

Children with minimal sensorineural hearing loss: prevalence, educational performance, and functional status.

OBJECTIVE: This study was designed to determine the prevalence of minimal sensorineural hearing loss (MSHL) in school-age children and to assess the relationship of MSHL to educational performance and functional status. DESIGN: To determine prevalence, a single-staged sampling frame of all schools in the district was created for 3rd, 6th, and 9th grades. Schools were selected with probability proportional to size in each grade group. The final study sample was 1218 children. To assess the association of MSHL with educational performance, children identified with MSHL were assigned as cases into a subsequent case-control study. Scores of the Comprehensive Test of Basic Skills (4th Edition) (CTBS/4) then were compared between children with MSHL and children with normal hearing. School teachers completed the Screening Instrument for Targeting Education Risk (SIFTER) and the Revised Behavior Problem Checklist for a subsample of children with MSHL and their normally hearing counterparts. Finally, data on grade retention for a sample of children with MSHL were obtained from school records and compared with school district norm data. To assess the relationship between MSHL and functional status, test scores of all children with MSHL and all children with normal hearing in grades 6 and 9 were compared on the COOP Adolescent Chart Method (COOP), a screening tool for functional status. RESULTS: MSHL was exhibited by 5.4% of the study sample. The prevalence of all types of hearing impairment was 11.3%. Third grade children with MSHL exhibited significantly lower scores than normally hearing controls on a series of subtests of the CTBS/4; however, no differences were noted at the 6th and 9th grade levels. The SIFTER results revealed that children with MSHL scored poorer on the communication subtest than normal-hearing controls. Thirty-seven percent of the children with MSHL failed at least one grade. Finally, children with MSHL exhibited significantly greater dysfunction than children with normal hearing on several subtests of the COOP including behavior, energy, stress, social support, and self-esteem. CONCLUSIONS: The prevalence of hearing loss in the schools almost doubles when children with MSHL are included. This large, education-based study shows clinically important associations between MSHL and school behavior and performance. Children with MSHL experienced more difficulty than normally hearing children on a series of educational and functional test measures. Although additional research is necessary, results suggest the need for audiologists, speech-language pathologists, and educators to evaluate carefully our identification and management approaches with this population. Better efforts to manage these children could result in meaningful improvement in their educational progress and psychosocial well-being.

Dissociation of cellular functions in Bacillus cereus by 5-fluorouracil.

Reich, Melvin (The George Washington University School of Medicine, Washington, D.C.), and H. George Mandel. Dissociation of cellular functions in Bacillus cereus by 5-fluorouracil. J. Bacteriol. 91:517-523. 1966.-5-Fluorouracil (FU) produced a marked inhibition of growth and deoxyribonucleic acid (DNA) synthesis in Bacillus cereus 569H. Protein and ribonucleic acid (RNA) synthesis were not specifically inhibited, and proceeded at the rate of turbidometric increase of the cells. Cell-wall synthesis, respiration, and penicillinase production continued in the presence of FU at essentially the control rate. The addition of equimolar concentrations of uracil and FU prevented growth inhibition but did not restore DNA synthesis. The addition of thymidine with FU did not relieve growth inhibition but did restore the DNA content to normal. Thymidine supplementation also increased the quantity of FU, but not uracil, incorporated into RNA and the acid-soluble fraction. The data indicate that inhibition of growth can be dissociated from inhibition of DNA synthesis and that more DNA is present in normal cells than is needed for growth and reproduction.

The sequelae of Haemophilus influenzae meningitis in school-age children.

BACKGROUND: Previous data on the consequences of Haemophilus influenzae type b meningitis for school-age children have been inconsistent, and much of the information on risk factors has been inconclusive. The present study was designed to evaluate the sequelae of this disease with a protocol for the comprehensive assessment of neuropsychological function. METHODS: Ninety-seven school-age children (mean age, 9.6 years), each of whom had a school-age sibling, were recruited from a survey of the medical records of 519 children treated for H. influenzae type b meningitis between 1972 and 1984 (at a mean age of 17 months) at the children's hospitals of Toronto, Ottawa, and Montreal. Of the 97 children, 41 had had an acute neurologic complication. Sequelae were assessed by comparing the index children with their nearest siblings on the basis of standardized measures of cognitive, academic, and behavioral status. RESULTS: Only 14 children (14 percent) had persisting neurologic sequelae: sensorineural hearing loss in 11 (unilateral in 6 and bilateral in 5), seizure disorder in 2, and hemiplegia and mental retardation in 1. Although the total sample of index children scored slightly below the siblings in reading ability, the 56 children without acute-phase neurologic complications (58 percent) were indistinguishable from their siblings on all measures. The differences between the groups were small even for the 41 pairs in which the index child had had an acute neurologic complication (mean full-scale IQ, 102 for the index children vs. 109 for the siblings). Sequelae were also associated with lower socioeconomic status and a lower ratio of glucose in cerebrospinal fluid to that in blood at the time of the meningitis. Behavioral problems were more prominent in index boys than index girls and in those who were older at the time of testing, but sex and age were not related to cognitive or academic sequelae. CONCLUSIONS: We find a favorable prognosis for the majority of children who are treated for meningitis caused by H. influenzae type b.

Particulate and ozone pollutant effects on the respiratory function of children in southwest Mexico City.

We assessed the contributions of particulate matter with aerodynamic diameters < or =10 and < or =2.5 microm (PM2.5 and PM10) and ozone (O3) to peak expiratory flow (PEF) and respiratory symptoms in 40 schoolchildren 8-11 years of age for 59 days during three periods in 1991 at a school in southwest Mexico City. We measured peak expiratory flow in the morning on the children's arrival at school and in the afternoon before their departure from school. Separately for morning and afternoon, we normalized each child's daily measurement of peak flow by subtracting his or her mean peak flow from the daily measurement. Child-specific deviations were averaged to obtain a morning and afternoon mean deviation (APEF) for each day. Mean 24-hour O3 level was 52 parts per billion (ppb; maximum 103 ppb); mean 24-hour PM2.5 and PM10 were 30 microg/m3 (maximum 69 microg/m3) and 49 microg/m3 (maximum 87 microg/m3), respectively. We adjusted moving average and polynomial distributed lag multiple regression analyses of APEF vs pollution for minimum daily temperature, trend, and season. We examined effects of PM2.5, PM10, and O3, on deltaPEF separately and in joint models. The models indicated a role for both particles and O3 in the reduction of peak expiratory flow, with shorter lags between exposure and reduction in peak expiratory flow for O3 than for particle exposure (0-4 vs 4-7 days). The joint effect of 7 days of exposure to the interquartile range of PM2.5 (17 microg/m3) and O3 (25 ppb) predicted a 7.1% (95% confidence interval = 11.0-3.9) reduction in morning peak expiratory flow. Pollutant exposure also predicted higher rates of phlegm; colinearity between pollutants limited the potential to distinguish the relative contribution of individual pollutants. In an area with chronically high ambient O3 levels, school children responded with reduced lung function to both O3 and particulate exposures within the previous 1 to 2 weeks.

Psychoeducational interventions for children and adolescents with attention-deficit/hyperactivity disorder.

Children with attention-deficit/hyperactivity disorder (ADHD) are at risk for impaired functioning in most areas related to school success. Despite the benefits of psychostimulants and other medications to alleviate problem behaviors associated with ADHD, these therapies are unable to completely ameliorate behavior problems for all children with this disorder. Additionally, whereas pharmacologic therapies do impact behavioral functioning they have not been shown to improve academic achievement. Therefore, attention needs to be directed toward psychoeducational interventions and their ability to increase the successful functioning of children with ADHD. The purpose of this article is to highlight some of the most prominent and empirically validated classroom intervention strategies for children with ADHD. Additionally, this article discusses the importance of choosing psychoeducational interventions based on functional assessment data. Finally, this article describes progress monitoring strategies that should be used to determine the efficacy of intervention strategies.
