SEM observation of cultured, mitogen-stimulated leukocytes. Cells obtained from patients with acute myeloblastic and chronic lymphocytic leukemias.

SEM observation of acute myeloblastic leukemia cells, incubated for 20 h with the mitogens pokeweed and phytohaemagglutinin, showed these to have elongated structures that were either smooth or partially covered by thumblike figures. By contrast, the chronic lymphocytic leukemia cells possessed more compact shapes and some were covered with blebs of varying sizes.

A benefit-cost analysis of two-dose measles immunization in Canada.

In 1992, because of the limitations of the one-dose measles immunization program, the National Advisory Committee on Immunization (NACI) recommended a two-dose measles immunization program to eliminate measles. More recently, NACI recommended also a special catch-up program to prevent predicted measles outbreaks and to achieve an earlier elimination of measles. The objective of this study was to complete a benefit-cost analysis of a two-dose immunization program with and without a mass catch-up compaign compared with the current one-dose program. The resulting benefit: cost ratios vary between 2.61:1 and 4.31:1 depending on the strategy used and the age of the children targeted. Given the parameters established for this analysis, the benefits of a second-dose vaccination program against measles far outweight the costs of such a program under all scenarios.

A study of self-perception in hyperactive children.

PURPOSE: This research aimed to describe self-perception among hyperactive children in comparison with a general population of children of the same age. DESIGN: A descriptive study with 116 children (between 6 and 11 years of age) distributed as follows: 57 hyperactive (20 girls and 37 boys) and 59 control group (25 girls and 34 boys). The hyperactive children were being treated at the outpatient clinic of a child psychiatry hospital. The children in the control group were recruited from a Quebec City elementary school. METHODS: Children in both groups participated in an interview during which they answered the Self-Perception Profile for Children (r = 0.90) consisting of six well-defined subscales. DATA ANALYSIS: Univariate analyses were used to describe the sociodemographic characteristics of both hyperactive and control group children. Groups were compared using t and chi-square tests. Univariate statistics were used to describe the characteristics of self-perception for each group overall and for each of the dimensions. Multivariate analysis was used to compare self-perception in hyperactive and control group children. RESULTS: All dimensions of self-perception were lower among hyperactive children than among children in the control group, except athletic competence, which was higher. Multivariate analysis indicated that the dimensions of scholastic competence, social acceptance, and behavioral conduct were problem areas for hyperactive children. CLINICAL IMPLICATIONS: Nursing care interventions for children with attention deficit hyperactivity disorder (ADHD) should be developed which assist children in increasing self-perception. This is a first step in developing a comprehensive plan of care.

Social support received by mothers of chronically ill children.

The main purpose of this study was to describe the characteristics of the social networks and social support of mothers of chronically ill children and adolescents. The data collected also allowed for the identification of the predisposing factors to receiving low social support among the mothers. Receipt of social support was assessed according to six dimensions: source of support, type of support, perceived need for support, satisfaction with the quality and the quantity of support, as well as most valued source of support. Results indicate that mothers wanted more support than they received, particularly in the areas of emotional, appraisal, and informative support. Furthermore, spouses, professionals, and immediate family members were identified by mothers as important sources of support. Discriminant analysis showed that the probability of receiving low support increased if the chronically ill child was an adolescent, the father had a higher level of education, and the family income was middle-low. Results are discussed in terms of the implications for intervention.

[Self perception: the key stone of nursing interventions with hyperactive children].

Denise Dumas, a nurse at the Hôtel-Dieu du Sacré-Coeur de Jésus hospital, in Quebec City, and Louise Pelletier, an associate professor at the Ecole des sciences infirmières of Université Laval, are interested in promoting understanding of problems linked to hyperactivity in school-age children. They suggest appropriate nursing interventions for child psychiatry units in hospitals and outpatient clinics. The authors give a definition of attention-deficit hyperactivity disorder, specifying its prevalence, etiology and treatment, and describe the behaviour of the hyperactive child. They go on to look at the concept of self-perception and deal with its development and its importance in children's lives. Most importantly, the authors suggest nursing interventions suited to the needs of hyperactive children.

Evaluation of the promotional materials used during the measles mass immunization campaign in Ontario and British Columbia.

OBJECTIVE: To evaluate the promotional materials used during measles mass immunization campaign. DESIGN: A telephone survey was conducted among parents of targeted children in Ontario and British Columbia (BC). RESULTS: The leaflet distributed at school was considered to be the most useful source of information for 79% and 69% of the parents of school-aged children in Ontario and BC, respectively. Newspaper articles (27%) and information obtained through public health nurses (24%) were the most appreciated sources of information for the parents of preschoolers only. There was a notable increase in the proportion of parents who considered measles immunization important as well as those who had concerns about measles immunization at the time of the interview compared with the period before the mass campaign. CONCLUSION: The leaflet distributed at school (for parents of school-aged children) and newspaper articles and information obtained from public health nurses (for the parents of preschoolers only) were found to be the most useful sources of information.
