Does knowledge about attention-deficit/hyperactivity disorder impact teachers' reported behaviors and perceptions?

This study surveyed elementary school teachers in Melbourne, Australia to investigate their knowledge about attention-deficit/hyperactivity disorder (ADHD) and its impact on their reported behavior toward and perceptions of children with ADHD. Consistent with previous international findings, teachers demonstrated good overall knowledge about ADHD, with strengths in knowledge of symptoms/diagnosis and weaknesses in knowledge of causes and treatments. To investigate how knowledge impacted reported behaviors and perceptions, teachers also read vignettes of children with ADHD symptoms and rated their reactions to these children. In general, teachers with high, and to some extent average, knowledge about ADHD reported more helpful behaviors (e.g., help-seeking for their students) and perceptions (e.g., perceive the benefit of behavioral and educational treatments). However, teachers with high and average knowledge also predicted that these children would be more disruptive in the classroom, and reported having less confidence in their ability to manage these children. Implications and need for future research are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A school-based schistosomiasis and intestinal helminthiasis control programme in Nigeria: acceptability to community members

In a population with high prevalences in schoolchildren of infection with hookworm (32.4%), Ascaris (22.9%) and Trichuris (2.5%), visible haematuria (17.9%), micro-haematuria (17%) and proteinuria (47.3%), the knowledge about transmission of schistosomiasis and acceptability of a school-based control programme were assessed. The community perceived schistosomiasis (80.6%) and intestinal helminthiasis (66.5%) as important health problems in school-age children and most people would prefer placement of the control programme in school because it would eliminate transportation cost to the health facility. They welcomed the idea of using teachers for detection of infection and drug administration. The health staff, on the other hand, were willing to work with teachers, but emphasized that teachers should be limited to organizational and supervisory roles while they do tests and administer the drug. This view was also shared by the officials in the state ministries of health and education.     

The clinical outcome in pregnancies of grand grand multiparous women

Recent public health concern about the Jacob-Creutzfeld disease related to administration of growth hormone in children or the "mad cow" disease in cattle fed contaminated products requires a review of the association between Jacob-Creutzfeldt disease and pregnancy. Four cases of this transmissible spongiform encephalopathy have been described in pregnant women and none of the offspring, currently 22, 10, 7 and 3 years of age, have developed the disease. Vertical transmission of Jacob-Creutzfeldt disease cannot however be excluded as it occurs in animals and since injections of cord blood and placenta extracts of women with this disease into mice brains has proven the presence of the infectious agent. The rarity of Jacob-Creutzfeldt disease in women of reproductive age and the particularly long incubation period of this type of encephalopathy would incite prudence and long-term follow-up to determine outcome in children born from disease women or who developed signs of the disease during the years following delivery.     

Does a direct cholera threat necessarily improve the knowledge, attitude and practices on the disease?

OBJECTIVE: To assess and compare the knowledge, attitude, practices and beliefs on cholera in Mudzi and Wedza districts. Mudzi district shares a long border with Mozambique where cholera was already prevalent before the study, while Wedza district does not share any international border. DESIGN: Cross sectional community based survey, Data was collected through interviews using a structured questionnaire. In villages, The source of water for domestic use as well as the toilets of the interviewed individuals were also inspected. SETTING: Two districts of Mashonaland East Province in Zimbabwe. SUBJECTS: Grade seven pupils, form four students and villagers. MAIN OUTCOME MEASURES: a. The level of knowledge on cholera. b. The prevalence of negative beliefs on the disease. c. The proportion of households using unsafe water. d. The proportion of households not using toilets. RESULTS: 140 and 116 individuals were interviewed in Mudzi and Wedza respectively. The level of knowledge on cholera was very poor in both districts and poorer in Mudzi which shares a border with Mozambique. Twenty pc of the people interviewed had negative beliefs towards the disease; 35pc were using unsafe water; 20pc of households did not have toilets and 4.5 to 7.7pc of the available toilets were not being used. CONCLUSION: Health education activities on cholera should target all districts with the same intensity. Specific strategies should be found in order to address the misconceptions which may hinder the control of cholera.     

Supporting children's mental health in schools: Teacher perceptions of needs, roles, and barriers.

There is a significant research to practice gap in the area of mental health practices and interventions in schools. Understanding the teacher perspective can provide important information about contextual influences that can be used to bridge the research to practice gap in school-based mental health practices. The purpose of this study was to examine teachers' perceptions of current mental health needs in their schools; their knowledge, skills, training experiences and training needs; their roles for supporting children's mental health; and barriers to supporting mental health needs in their school settings. Participants included 292 teachers from 5 school districts. Teachers reported viewing school psychologists as having a primary role in most aspects of mental health service delivery in the school including conducting screening and behavioral assessments, monitoring student progress, and referring children to school-based or community services. Teachers perceived themselves as having primary responsibility for implementing classroom-based behavioral interventions but believed school psychologists had a greater role in teaching social emotional lessons. Teachers also reported a global lack of experience and training for supporting children's mental health needs. Implications of the findings are discussed.

Cryptosporidia--who is at risk?

Cryptosporidium parvum is a coccidian parasite originally described a century ago and, until recently, not considered to be a human pathogen. It has a complex life cycle, including both sexual and asexual reproduction, an auto-infectious cycle, and the ability to complete its development within a single host. The transmission form is a robust, environmentally resistant oocyst, excreted in the stool, which can exist for long periods of time in the environment. Because animals, in particular domesticated livestock, are its primary host, human infection is usually zoonotic. Oocysts often find their way into water supplies, and it resists chlorination and is incompletely filtered from processed drinking water supplies, even when filtration is working optimally. Transmission via ingestion of fecally contaminated swimming pool water, food, fomites, and sexual activities facilitating fecal-oral inoculation have been demonstrated. The major target of C. parvum in the host is the intestinal epithelial cell, resulting in diarrhea, sometimes profuse and persistent, although it may also infect other organs such as the gall bladder and lungs. Pathogenesis involves attachment, probably via a sporozoite lectin, invasion, probably involving apical organelles, replication within a parasitophorous vacuole with the host cell membrane, causing cellular dysfunction. Diagnosis is generally made by visualization of the oocyst form in stool by staining methods, the best of which appears to be auramine and fluorescence microscopy. Those at greatest risk are immunocompromised adults and children, especially those with AIDS, children in day care, travelers to endemic regions, dairy or cattle farm workers of their families or contacts, household contacts of cases or carriers, and possibly owners of infected dogs or cats or their neighbors. There is no specific therapy available, however in the immunocompetent host the illness is self-limited, lasting from a few days to 3 weeks, and long term carriage is uncommon. In the immunocompromised host, infection is prolonged, sometimes asymptomatic, but may result in chronic debilitating diarrhea with dehydration, malabsorption and wasting. Public health measures to reduce contamination of water supplies and vigilant surveillance will reduce the risk to populations. Reducing behaviors favoring fecal-oral transmission, such as certain sexual activities, and scrupulous hygiene in the day care setting would also reduce the likelihood of transmission but not eliminate it. Given our lack of knowledge about Cryptosporidium biology and pathogenesis, high priority should be given to research designed to increase our understanding of the organism and improve the chance of developing useful therapeutic or preventative drugs or strategies.     

Video as a medium of oral health education for children with mental handicaps

This study assessed the usefulness, appropriateness, and relevance of a video as an oral health education medium for children with mental handicaps and for preschool groups where children with mental handicaps and healthy children are taught together. The evaluated video was designed for children with mental handicaps but was also recommended for integrated groups. Forty children with mental handicaps from four special education classes and two nursery school groups, 151 normal children from 11 nursery school groups, and the teachers of these classes and groups evaluated the material. The assessment of the material's value was based on the teachers' records of their experiences with the material, their records of the children's opinions and discussions about the material, and their records of drawing interviews with the children. Based on the evaluation, it is apparent that, when used by trained teachers, professionally made videos designed for children with mental handicaps can be useful and valuable aids in educating children of different levels of mental and social development about oral health. Integrated groups need videos featuring both children with mental handicaps and normal role models and with a diversity of contents that will interest and challenge both types of audiences.E.     

What kind of information does the health services give to children with asthma and their parents?

Good information to families who have children with bronchial asthma is essential for treatment and in helping the family to cope. The aim of this study was to find out what kind of information the parents meant they had received, their knowledge about asthma, and what sanitary measures had been taken at home. A questionnaire was sent to all children (N = 431) who, during a five year period, were entered into the records of the Department of Paediatrics, Innherred Hospital, Norway, with the diagnosis bronchial obstruction. A selected group of 55 children and their parents were also interviewed. The results showed that the parents were not satisfied with the information they had received about the illness and about effects and side effects of the medication. Furthermore, their knowledge about these matters was not satisfactory, judged both by themselves and by the interviewer. It was more difficult to quit smoking or to stop keeping animals than to do extra cleaning at home. Few parents were informed about their possibilities of receiving financial support and about patient organisations. Only in a few cases did the health service provide the school with information on the child's disease.     

Articular cartilage repair

The net and basic reproduction numbers are among the most widely-applied concepts in infectious disease epidemiology. A net reproduction number (the average number of secondary infectious cases resulting from each case in a given population) of above 1 is conventionally associated with an increase in incidence; the basic reproduction number (defined analogously for a 'totally susceptible' population) provides a standard measure of the 'transmission potential' of an infection. Using a model of the epidemiology of tuberculosis in England and Wales since 1900, we demonstrate that these measures are difficult to apply if disease can follow reinfection, and that they lose their conventional interpretations if important epidemiological parameters, such as the rate of contact between individuals, change over the time interval between successive cases in a chain of transmission (the serial interval). The net reproduction number for tuberculosis in England and Wales appears to have been approximately 1 from 1900 until 1950, despite concurrent declines in morbidity and mortality rates, and it declined rapidly in the second half of this century. The basic reproduction number declined from about 3 in 1900, reached 2 by 1950, and first fell below 1 in about 1960. Reductions in effective contact between individuals over this period, measured in terms of the average number of individuals to whom each case could transmit the infection, meant that the conventional basic reproduction number measure (which does not consider subsequent changes in epidemiological parameters) for a given year failed to reflect the 'actual transmission potential' of the infection. This latter property is better described by a variant of the conventional measure which takes secular trends in contact into account. These results are relevant for the interpretation of trends in any infectious disease for which epidemiological parameters change over time periods comparable to the infectious period, incubation period or serial interval.     

Rural school nurses' attitudes about AIDS and homosexuality

The AIDS epidemic has spread to rural areas of the United States. Conservative rural communities are facing the challenge of having children with HIV entering school. School nurses, as the only health care providers in the schools, are in a strong position to facilitate the education of children with HIV and to provide AIDS education to students, faculty, and parents. School nurses' knowledge and attitudes about AIDS and people with AIDS influence their effectiveness in prevention activities and care of HIV-infected children. This study examined the relationship between specific demographic, practice, and cultural variables and rural school nurses' attitudes about AIDS and homosexuality. Sixty-nine school nurses responded to a mailed questionnaire as part of a larger study of rural nurses. Results indicate attitudes about homosexuality were related to nurses' homosexual knowledge and religious beliefs while attitudes about AIDS were related to nurses' willingness to care for people with AIDS and feeling prepared to do so.     

Prolongation of fentanyl-induced decreased arousal by clonidine

This community based, case management intervention study was done to assess the effectiveness of Community Health Workers (CHWs) in case detection and management of pneumonia in children under five years of age. Twenty-two volunteers (school teachers and students) were selected as CHWs from Rehri village, in Sindh, Pakistan and trained on World Health Organization (WHO) recommended National/Acute Respiratory Tract Infection (ARI) guidelines at the Department of Paediatrics, Dow Medical College, Civil Hospital, Karachi. The CHWs had no prior health education. The intervention was the use of CHWs to detect and manage pneumonia in children under five years of age in Rehri village. Two medical officers supervised the post-training activities of CHWs in the village during the study period. Between December, 1992 and May, 1993, 442 episodes of pneumonia (very severe disease 10, severe pneumonia 54 and simple pneumonia 378) were detected and managed by trained CHWs. The medical officers agreed with the CHWs for classification and treatment in 356 (81%) cases. This study suggests that in areas where there is a shortage of trained health care professionals, educated community members such as school teachers can be trained to detect and manage pneumonia in their community.     

Evaluation of vectors of Chagas' disease eradication programs in Chile by serological study of children under 10 years old

Chagas' disease is a parasitic zoonosis with high prevalence in Chile. It is distributed in rural and periurban section in the northern most seven out of thirteen regions in which the country is divided, and affects about 142,000 individuals dispersed in most of the 165 counties sited in the chagasic zone. Triatoma infestans--intradomiciliary species--is the main and practically exclusive vector of Trypanosoma cruzi. Diverse tools may be utilized in order to interrupt the domestic cycle of transmission of T. cruzi: health education, housing improvement and elimination of vectors by dwelling insecticide sprayings. This last resource has received priority in Chile in the last 12 years. To evaluate the effectivity of the programs for eliminating T. infestans a serological study for Chagas' disease--comprising 8,767 children less than 10 years old from 27 rural counties insecticide sprayed in the last 12 years--was carried out. A global total of 125 (1.4%) children resulted positive, figure significantly lower than 5.4% found in 1982-1990 in the same age group. Distribution by regions of positive individuals showed a decrease of prevalence in each of them: III Region, from 9.8 to 1.0%, IV Region, 7.2 to 2.0%, V Region, 5.2 to 1.9%, and Metropolitan Region, 1.4% to 0.6. Even though positive children have still been found in 46.7% of localities of the studied counties, it is possible to affirm that the vector control programs have been effective and must be maintained, and increased in those localities with T. cruzi infection in children under 10 years of age, with the general aim of eradicate Chagas' disease transmission in Chile before 2000.     

Differences in attitudes toward sex-typed behavior of nonretarded and retarded children

The present study was an initial attempt at understanding gender constancy in retarded children. Stories about retarded or nonretarded boys or girls were given to teachers and caretakers of retarded children and teachers of nonretarded children. The stories described children in four sex-stereotyped activities. Respondents rated each child in the stories on scales of typicality and acceptability. Results indicated that, while nonretarded children were rated as typical when engaging in sex-appropriate, desirable play activities, retarded children were rated as typical when engaging in undesirable activities, regardless of sex appropriateness. Different professional groups appeared to use different criteria when judging the children in the stories.     

Assessing knowledge conveyed in gesture: Do teachers have the upper hand?

Children's gestures can reveal important information about their problem-solving strategies. This study investigated whether the information children express only in gesture is accessible to adults not trained in gesture coding. Twenty teachers and 20 undergraduates viewed videotaped vignettes of 12 children explaining their solutions to equations. Six children expressed the same strategy in speech and gesture, and 6 expressed different strategies. After each vignette, adults described the child's reasoning. For children who expressed different strategies in speech and gesture, both teachers and undergraduates frequently described strategies that children had not expressed in speech. These additional strategies could often be traced to the children's gestures. Sensitivity to gesture was comparable for teachers and undergraduates. Thus, even without training, adults glean information, not only from children's words but also from their hands. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Knowledge and information about ADHD: evidence of cultural differences among African-American and white parents

Attention deficit hyperactivity disorder (ADHD) is considered the most common child psychiatric disorder in the United States of America. Despite the high prevalence (estimated at 3-5%), little is known about the level and source of knowledge about ADHD among those affected by the disease, and about cultural and ethnic variations in knowledge levels and information sources. This represents a serious deficit, because health behavior, including demand for health services, is thought to be strongly influenced by knowledge or beliefs held by individuals and their networks. Furthermore, recent research suggested minority children may be less likely to receive services for ADHD. To examine possible differences in ADHD knowledge and information source, a sample of 486 African-American and white parents of children at high risk for ADHD were surveyed by telephone and subsequently participated in face-to-face interviews addressing their explanatory models of ADHD. Results revealed significant ethnic differences in knowledge and sources of information about ADHD. Fewer African-American parents than white parents indicated that they had ever heard of ADHD (69% compared to 95%, P < 0.001), or that they knew some or a lot about it (36% compared to 70%, P < 0.001) African-American parents were more likely to attribute ADHD to excessive sugar in the diet than whites (59% compared to 30.0%, P < 0.001). Finally, even though the physician was listed as the most preferred information source for both groups, only 17.5% of African-American parents reported they had received information about ADHD from the physician compared to 29% of whites (P < 0.01). African American parents reported less use of and less preference for written informational materials (newspapers, journals, library) than white parents. We conclude that substantially more research should be undertaken to examine the relationship between ethnicity and ADHD knowledge, to inform culturally appropriate education campaigns and to improve access to services for this important treatable child mental health condition.     

Health effects of attending a public swimming pool: follow up of a cohort of pupils in Paris

OBJECTIVES: This study aimed to determine the health effects of attending a well-kept school swimming pool maintained according to French public health regulations. METHODS: This prospective month long study was carried out on a randomised sample of pupils aged 5 to 18 years who attended a private French school with two swimming pools. The children surveyed, helped by their parents, had to fill in questionnaires about their bathing habits and symptoms during the survey period. Inspections of the pool complex were made and these included physicochemical and bacteriological analyses of the pools' water. PARTICIPATION: The response rates achieved were 70% at primary and middle school levels but only 25% in the high school pupils. Because of this older teenagers were excluded from the final analysis (of 246 children). RESULTS: Compared with non-bathers, bathers experienced fatigue and eye irritation significantly more often (p < 0.001). The eyes were red (38% of bathers) and/or watery (16%) after swimming but this resolved spontaneously within 24 hours. Bathing behaviour (bath duration, head immersion, wearing swimming goggles) did not affect these incidence rates noticeably. There were no differences between bathers and non-bathers with regard to other symptoms, especially otolaryngological ones. This survey does not allow definite conclusions to be made about verrucas because 22% of non-bathers were exempted from swimming because of verrucas that they might have caught previously in a pool. CONCLUSIONS: Except for verrucas, the methodology was adequate and daily self reporting of symptoms was feasible. This college largely recruits pupils from higher social classes and is not therefore representative of schools in Paris.     

Quality of life. Issues for persons with neuromuscular diseases

Improving quality of life has always been a goal of rehabilitation medicine. However, health care providers often do not know much about the quality of life of individuals with neuromuscular diseases, nor what factors are critical to achieving a good quality of life. Lack of knowledge about subjective quality of life factors can negatively influence expectations and selection of treatments. In the most glaring cases, a physician's subjective but incorrect assessment of a disabled individuals' quality of life may prevent life-sustaining interventions. As a group, the quality of life of individuals with NMD is not much different than nondisabled controls and is substantially better than presumed by the general public and, often times, by health care workers. Nevertheless, their quality of life is reduced in certain areas. Surprisingly, level of disability is not a critical factor that significantly alters life satisfaction. Presumably, this is because physical functioning has been adequately managed. The greatest problems that individuals with neuromuscular disease identified were: lack of information about the disease and services; poor coordination of services; negative attitudes; and a diminished expectation of their potential. In addition, people with severe disabilities had significant problems obtaining, financing, and managing personal care attendants. Factors related to a good quality of life were related to perceived control, perceived health status, but not disability. The more that people could do for themselves, either on their own or with personal care assistants, assistive devices, and use of technology, the better their quality of life.     

Health behavior, perceptions, practices, and decision making: sub-national and socio-demographic differentials in Bangladesh, 1995

The study examines health behavior, perceptions, practices, and decision making using data from the 1995 Health and Demographic Survey conducted by the Bangladesh Bureau of Statistics. Knowledge about causes of diarrhea and food contamination were higher than knowledge about causes of nightblindness and worm infestation but this knowledge is inadequate. The household's economic condition and the respondent's education were found to be positively associated with disease knowledge and food contamination; the same is also true for health behavior and practices. Sub-national variation in disease knowledge and food contamination exists but did not correspond always with the health behavior and practices. Decisions regarding treatment of disease were made by the husband and wife together in two-thirds of the cases, however, it was not uniform across socio-demographic and sub-national categories.     

Knowledge of tuberculosis in high-risk populations: survey of inner city minorities

SETTING: Educational programs targeted toward individuals at risk for tuberculosis are needed. As an initial step in developing future programs, the present study was designed to determine the baseline knowledge about tuberculosis in at-risk individuals. METHODS: Face-to-face surveys were conducted with 505 minority subjects in the Kansas City Metropolitan area; health care providers were excluded. Thirty-six queries directed toward self-perceived and actual tuberculosis knowledge were asked. Data were tabulated and per cent correct response was determined. RESULTS: Completed surveys were available from 505 subjects: 342 females and 163 males. Most (97%) of the subjects were African Americans, with 57% between the ages of 21-40. Over two-thirds were high school graduates, and 77% reported an estimated total household annual income of <$20000. Self-perceived knowledge about tuberculosis was rated as 'little' or 'nothing' by 60% of respondents. The overall correct response score was 61%, with 55% correct response to queries related to etiology, 53% for identification of high-risk populations, 57% for possible routes of transmission, 89% for symptoms, and 49% for treatment. Males, those with annual incomes >$20000, and individuals 51-70 years old had the highest scores. CONCLUSIONS: In this high-risk inner-city population surveyed, knowledge deficits in the etiology, transmission, and treatment of tuberculosis were identified.     

An epidemiological study of the adolescent nonfatal unintentional injuries in Taiwan

Despite the observation of TBE cases after consumption of raw milk from cows or goats, so far the proof of the alimentary route of human infection has not been possible. In the regions of southwestern Germany, where TBE is known to be endemic, milk-borne TBE infections have not yet been observed. To assess the significance of raw milk consumption for viral transmission, a cross-sectional study (114 forestry workers, 177 individuals exposed during their leisure-time activities, 170 non-exposed individuals) and a case-control study (50 TBE patients, 150 controls) were carried out. The results of the study show that both the time spent in the endemic region and also the professional exposure to ticks do influence TBE seroprevalence, whereas the consumption of raw milk (milk directly from the farmer) is no major risk factor for TBE infection or disease. Among leisure-time activities, only hunting has an effect comparable to the one of the professional exposure to ticks. Besides epidemiological data obtained in humans, serological investigations of cows were performed. Here it is shown that milk-producing animals are involved in the natural transmission of TBE virus. Since former studies had shown that TBE-viremic animals excrete the virus with the milk--although over a short period and in low concentrations--the occurrence of milk-borne TBE infections cannot be excluded in the endemic regions of south-western Germany. However, from the epidemiological point of view, their significance may be neglected. Vaccination has proven the most reliable means of TBE prevention, irrespective of the route of infection.
