Abstract A survey of orthodontic treatment need was carried out among randomly selected rural Nigerian adolescents using the index of orthodontic treatment need. Altogether, 704 subjects (381 boys and 323 girls) aged 12–18 years (mean 14.8, SD 1.79) were recruited in the study. The results indicated that 12.6% of the population were in objective need of orthodontic treatment. Whilst there was a discrepancy in the proportions of Nigerian adolescents needing orthodontic treatment on aesthetic and dental health grounds, girls were found to have a more attractive dental appearance and less orthodontic treatment need than boys. However, the differences were not statistically significant (P > 0.05). The correlation between the orthodontist's and the subject's rating of dental appearance was found to be low (r=0.35). The study also provided reliable baseline data for planning orthodontic services in Nigeria especially in areas where there are no dental services. 相似文献

This study examined the impact of controllability of onset (i.e., means of transmission), disease type (HIV and lung cancer), and culture (Kenya and U.S.) on stigmatizing attitudes and goals for supportive communication. Four hundred sixty-four Kenyan students and 526 American students, and 441 Kenyan nonstudents and 591 American nonstudents were randomly assigned to 1 of 12 hypothetical scenario conditions and asked to respond to questions regarding 3 different types of stigmatizing attitudes and 6 types of supportive communication goals with respect to the character in the scenario. Means of transmission had a strong effect on the blame component of stigma, but none on cognitive attitudes and social interaction components. Similarly, although an effect for means of transmission emerged on intention to provide "recognize own responsibility" and "see others' blame" types of support, no effect was evident for most other supportive interaction goals. Although effects for culture were small, Kenyan participants, student and nonstudent alike, were not as quick as American participants to adopt goals of communicating blame in any direction. Implications for measurement of stigma in future research are discussed. 相似文献

Background
Survey data are traditionally collected using pen-and-paper, with double data entry, comparison of entries and reconciliation of discrepancies before data cleaning can commence. We used Personal Digital Assistants (PDAs) for data entry at the point of collection, to save time and enhance the quality of data in a survey of over 21,000 scattered rural households in southern Tanzania. 相似文献16.
Orofacial injuries associated with prehospital management of febrile convulsion in Nigerian children
Kizito C. Ndukwe Morenike O. Folayan Vincent I. Ugboko Jerome B.E. Elusiyan Olajumoke O. Laja 《Dental traumatology》2007,23(2):72-75
Abstract – The aim of this prospective study was to determine in a population of pediatric patients with febrile convulsions the prevalence and pattern of orofacial and dental injuries caused by traditional remedies used in a suburban Nigerian community. Over the study period of 28 months, 75 cases of febrile convulsion presented to the Children's Emergency unit of our hospital. Of these, 27 children (36%) sustained orofacial injuries caused by forceful insertion of a spoon into the mouth (96.3%) or a bite (3.7%) during convulsive episodes. The ages of the patients ranged from 12 to 84 months with a mean 39.8 ± 18.3 months. There were 15 males and 11 females with a male to female ratio of 1.4:1. The orofacial and dental injuries sustained from prehospital treatment at home were lacerations and bruising of soft tissues including lips, tongue, mucosa and commissures and tooth subluxation, displacement or avulsion. Other injuries sustained outside the mouth include second-degree burns to the feet, a chin laceration and facial bruises resulting from a fall. Many oral injuries were overlooked by pediatricians. Prompt recognition and appropriate management of febrile convulsion would be of great benefit to the pediatric patients. 相似文献

In Kenya, HIV diagnosis is not routinely carried out in infants, and yet rapid diagnosis could improve access to lifesaving interventions. A cheap and readily accessible service can resolve this problem, if feasible. In this pilot study the feasibility and costs of provision of an infant HIV diagnosis service in Kenya are evaluated. Dried blood spots (DBS) were collected from infants exposed to HIV, sent to a central testing laboratory and tested using the Roche Amplicor v. 1.5 DNA PCR kit. The results were then dispatched to health facilities within a week. A total of 15.4% of the samples tested HIV+ despite the widespread access to prevention of mother to child transmission (PMTCT) programs in Kenya. The cost per test at 21.50 USD is prohibitive and will limit access to diagnosis. It remains to be seen whether the increase in testing will immediately lead to an increase in access to antiretroviral therapy (ART) services for infants. 相似文献
