This study analysed the prevalence, demography, soft- and hard-tissue injury patterns, management and complications of gunshot injuries to the maxillo-facial region in 301 patients treated at Groote Schuur Hospital, Cape Town. The number of patients presenting with maxillo-facial injuries caused by gunshot increased over the 15-year study period. The majority were caused by civilian type low-velocity hand-guns and were purposefully and intentionally inflicted by others. Males in their third decade of life and of low socioeconomic status were most often the victims. The wounding effects of these low-velocity injuries were characteristic--small rounded entrance wounds, causing fragmentation of teeth and comminution of the underlying bone, usually without any exit wounds. A comminuted displaced type of fracture pattern was most frequently observed. Special investigations included plain film radiographs with more sophisticated investigations being requested where indicated. Definitive surgical management was initiated by early soft-tissue debridement. Both the mandibular and maxillary fractures had more open than closed reductions. Bone continuity defects as a result of the initial injury were usually reconstructed secondarily using free autogenous bone grafts. All the patients received anti-tetanus toxoid on admission and the majority received antibiotic treatment. The most common complications were sepsis, ocular and neurological complications and limitation of mouth opening. The postoperative sepsis rate was high (19%). The wounding effects of these low-velocity missile injuries are devastating and pose a treatment challenge to the maxillo-facial surgeon. 相似文献

OBJECTIVES: The first democratic government elected in South Africa in 1994 inherited huge inequities in health status and health provision across all sections of the population. This study set out to assess the impact of the new government's commitment to address these inequities and implement policies to improve population health in general and address inequalities in health care in particular. DESIGN: A 1998 household survey assessed many aspects of health delivery, including their own perceived and actual access to health care among different segments of South African society. RESULTS: Race was the main predictor of perceived changes in access to health care, with black, coloured-and Indian respondents significantly more likely to feel that access had improved since 1994, compared with white respondents. Socio-economic status (SES) was the main predictor of actual access to health care, with low and middle SES classes significantly less likely to access care when ill. CONCLUSIONS: One-third of respondents perceived health care access to have improved between 1994 and 1998, and this response was partially determined along racial lines. About one-quarter reported an inability to access health care when they required it, and this response was partially determined along socio-economic lines. This set of contrasting responses suggests that at a political level perceptions are largely influenced by race, but at the operational level actual access is influenced by SES. 相似文献

The demand for genetic services by women with a family history of breast cancer has increased exponentially over the last few years. It is important that risks to women are accurately assessed and that processes are in place for appropriate counselling and management. The classification of risk into average, moderate, and high, depending upon the assessed lifetime risk of breast cancer, allows for the management of moderate risk women within cancer units and high risk women within the regional genetic centres. Management of high risk women includes discussion of options including screening, chemoprevention, and preventive surgery. The majority of these options are still unproven in the long term and continuing research is needed for their evaluation. Mutation screening and predictive testing are now a reality for a minority of families, allowing for a more informed basis for decisions regarding management options. 相似文献

OBJECTIVE: The first democratic government elected in South Africa in 1994 inherited huge inequalities in health status and health provision across all sections of the population. This study set out to assess, 4 years later, the influence of race and socioeconomic status (SES) on perceived quality of care from health care providers. DESIGN: A 1998 countrywide survey of 3820 households assessed many aspects of health care delivery, including levels of satisfaction with health care providers among different segments of South African society. RESULTS: Fifty-one percent (n = 1953) of the respondents had attended a primary care facility in the year preceding the interview and were retained in the analysis. Both race and SES were significant predictors of levels of satisfaction with the services of the health care provider, after adjusting for gender, age, and type of facility visited. White and high SES respondents were about 1.5 times more likely to report excellent service compared with Black and low SES respondents, respectively. CONCLUSION: In South Africa, race and SES are not synonymous and can no longer be considered reliable proxy indicators of one another. Each has distinct and significant but different degrees of association with client satisfaction. Any assessment of equity-driven health policy in South Africa should consider the impacts of both race and SES on client satisfaction as one of the indicators of success. 相似文献

Background
Oral potentially malignant disorders (OPMDs) could have a significant psychological impact on patients, principally because of the unknown risk of malignant transformation, while the physical and functional impairments could differ. This study aimed to assess the impact of three different OPMDs and their disease stages on the quality of life (QoL) of affected patients.Methods
Oral leukoplakia (OL), oral lichen planus (OLP) and oral submucous fibrosis (OSF) patients who were undergoing treatment at an oral medicine clinic of a dental teaching hospital in India were the study population. All subjects completed the recently developed OPMDQoL questionnaire and a short form 12 item (version 2) health survey questionnaire (SF‐12v2). OPMDQoL questionnaire consists of 20 items over four dimensions. A higher score denotes poor OHRQoL. SF‐12v2 has two components, a Physical Component Summary (PCS) and Mental Component Summary (MCS).Results
A total of 150 subjects (50 each of OL, OLP and OSF) participated. OL patients (37.7 ± 7.9) reported significantly better OPMDQoL scores than OLP (47.3 ± 5.8) and OSF (45.4 ± 9.2) patients. OLP patients reported significant problems in obtaining a clear diagnosis for their condition, more so than the other OPMDs. OL patients reported fewer problems for the dimension, “physical impairment and functional limitations” than the OLP and OSF patients. A significant trend was observed with the overall OPMDQoL and MCS, deteriorating as the disease stage increased.Conclusions
OLP and OSF have a significant impact on the QoL of affected individuals: OL less so. Increasing stage of the disease is associated with worsening QoL. 相似文献8.

BRCA1 and BRCA2 are major breast cancer susceptibility genes. Nineteen single nucleotide polymorphisms (SNPs) at 18 loci have been associated with breast cancer. We aimed to determine whether these predict breast cancer incidence in women with BRCA1/BRCA2 mutations. BRCA1/2 mutation carriers identified through the Manchester genetics centre between 1996 and 2011 were included. Using published odds ratios (OR) and risk allele frequencies, we calculated an overall breast cancer risk SNP score (OBRS) for each woman. The relationship between OBRS and age at breast cancer onset was investigated using the Cox proportional hazards model, and predictive ability assessed using Harrell's C concordance statistic. In BRCA1 mutation carriers we found no association between OBRS and age at breast cancer onset: OR for the lowest risk quintile compared to the highest was 1.20 (95% CI 0.82–1.75, Harrell's C = 0.54), but in BRCA2 mutation carriers the association was significant (OR for the lowest risk quintile relative to the highest was 0.47 (95% CI 0.33–0.69, Harrell's C = 0.59). The 18 validated breast cancer SNPs differentiate breast cancer risks between women with BRCA2 mutations, but not BRCA1. It may now be appropriate to use these SNPs to help women with BRCA2 mutations make maximally informed decisions about management options. 相似文献
