Cleaning the womb: constructions of cervical screening and womb cancer among rural black women in South Africa.

In South Africa problems with current cervical screening uptake, including low coverage and loss of screened women to follow-up, have been identified. This paper presents the findings of an anthropological study of rural Black women's perceptions and understandings of cervical symptomatology, screening and cancer conducted among three different language groups in South Africa. The data collected indicate that women were screened when presenting with symptoms of reproductive tract infection, with the result that for many the smear came to be associated with the diagnosis and treatment of sexually transmitted diseases (STDs). In some cases the smear was said itself to "clean" the womb. The results were often interpreted by women as signifying womb "dirtiness" and confirming the presence of symptomatic reproductive disease for which they had initially presented to the biomedical facility. Several barriers to screening were identified including fear of vaginal exposure, expectation of pain, being asymptomatic, and gender of the practitioner. In addition women perceived womb cancer to be invariably terminal, knowledge which was constructed from personal and community experience of the illness. The illness was closely associated with (usually female) "promiscuity". The authors discuss the implications of the data for healthworkers and health promotion specialists, in particular the association of the smear with STDs, the way in which women are recruited for screening, the perceived terminality of womb cancer, and the processes by which local knowledge about illness is constructed. The findings demonstrate the importance of medical anthropology in contributing towards the provision of effective and locally appropriate healthcare.

The epidemiology of incomplete abortion in South Africa. National Incomplete Abortion Reference Group.

OBJECTIVE: To describe the epidemiology of incomplete abortion (spontaneous miscarriage and illegally induced) in South Africa. DESIGN: Multicentre, prospective, descriptive study. SETTING: Fifty-six public hospitals in nine provinces (a stratified, random sample of all hospitals treating gynaecological emergencies). PATIENTS: All women of gestation under 22 weeks who presented with incomplete abortion during the 2-week study period. MAIN OUTCOME MEASURES: Incidence of, morbidity associated with and mortality from incomplete abortion. MAIN RESULTS: An estimated 44686 (95% CI 35633-53709) women per year were admitted to South Africa's public hospitals with incomplete abortion. An estimated 425 (95% CI 78-735) women die in public hospitals from complications of abortion. Fifteen per cent (95% CI 13-18) of patients have severe morbidity while a further 19% (95% CI 16-22) have moderate morbidity, as assessed by categories designed for the study which largely reflect infection. There were marked inter-provincial differences and inter-age group differences in trimester of presentation and proportion of patients with appreciable morbidity. CONCLUSIONS: Incomplete abortions and, in particular, unsafe abortions are an important cause of mortality and morbidity in South Africa. The methods used in this study underestimate the true incidence for reasons that are discussed. A high priority should be given to the prevention of unsafe abortion.

Barriers to cervical screening: women's and health workers' perceptions.

Cancer of the cervix is the most common cause of cancer mortality among Black South African women. Mortality can be reduced by an effective screening programme. Such a programme is being considered for implementation in South Africa. It is important that the implementation of a national screening programme be based on solid understanding of the current situation as well as the anticipated barriers to the effectiveness of the programme. This qualitative study was done at three rural sites in order to explore the barriers to effective utilisation of cervical screening from the perspectives of women and health workers. The aim was to inform the local service organisers as well as the policy process when planning the new screening programme. There were interesting similarities and differences between the barriers that were identified by the health workers and those by the women. Those identified by the health workers included several structural problems associated with the service such as busy clinics and problems of access including lack of transport, the mobility of the people and opposition from men. None of the women spoke of these service and access factors. Women emphasised issues surrounding the actual procedures which were based on their experiences and information they had gained from friends and other community networks. The barriers identified by women are amenable to change through careful attention to health education and the circumstances of the test. If the new screening policy is to be implemented nationally and be successful in recruiting cervical cancer cases, nurses will have a key role in identifying and overcoming barriers to smear uptake at a local level. This study has shown the importance of listening to patients in this process.

Backstreet abortion: women's experiences.

AIM: This was a descriptive study aimed at exploring the personal experiences of women who induce abortion and the circumstances surrounding induced abortion. METHODS: The study was conducted in six public hospitals in four different provinces: Baragwanath (Gauteng), Groote Schuur and Tygerberg (Western Cape), King Edward and R.K. Khan (Kwa-Zulu/Natal) and Livingstone (Eastern Cape). In-depth interviews were conducted with 25 African, Indian and Coloured women admitted to the hospitals following backstreet abortions. The study gave women the opportunity to "speak for themselves" about "why" and "how" and the context in which the unsafe induced abortions occurred. RESULTS: The findings show that a host of factors were important in the circumstances leading to unwanted pregnancy and induced abortion: socio-economic, cultural, psychological and societal. Disempowerment in relationships combined with financial pressures constituted the background as to why women felt forced to terminate their pregnancies. The perceived need for termination was found to over-ride all other considerations, including religious ones. The ways in which women attempted to procure abortion, both through legal and illegal routes, are presented. Wider social and legal discourses an abortion were found to be an important factor in how women experienced their situation.

Meanings of community.

Community participation in health promotion is one of the central tenets of the WHO's Health For All strategy. Throughout the United Kingdom, 'Health For All' projects have been established and efforts dedicated to the pursuit of community participation in health promotion. Despite this zeal, the deceptively simple notion of 'community' is one of the most contested in the social sciences. Taking this as its point of departure, this paper reviews the meanings of 'community' in social sciences and health literatures. Based on empirical data, it then explores meanings of 'community' for people who are involved in generating community participation in health promotion in the context of four U.K. Health For All projects. A wide variety of different meanings are found; what they share in common is that they are each constructed by people who regard themselves as 'non-members' of these 'communities' and that the views of the putative 'members' are not taken into account in their construction. This substantially differs from meanings of community constructed by their 'members', as represented by Anthony Cohen, where community members' perceptions of sharing are central to the delineation of boundaries. This paper argues that there is a fundamental difference between the construction of communities by 'members' and 'non-members'. In the former case notions are sharing are integral to the construction, in the latter case they are assumed. In the final part of the paper we examine informants daily experiences of operationalising the 'communities' which they construct and argue that commonly their assumptions of sharing prove unfounded. We conclude by arguing that recognition of the differences in the construction of communities by members and non-members is essential, not least because it demands a fundamental rethinking of the notion of community participation in health.

What is participatory research?

Research strategies which emphasize participation are increasingly used in health research. Breaking the linear mould of conventional research, participatory research focuses on a process of sequential reflection and action, carried out with and by local people rather than on them. Local knowledge and perspectives are not only acknowledged but form the basis for research and planning. Many of the methods used in participatory research are drawn from mainstream disciplines and conventional research itself involves varying degrees of participation. The key difference between participatory and conventional methodologies lies in the location of power in the research process. We review some of the participatory methodologies which are currently being popularized in health research, focusing on the issue of control over the research process. Participatory research raises personal, professional and political challenges which go beyond the bounds of the production of information. Problematizing "participation', we explore the challenges and dilemmas of participatory practice.

Are patients with low serum thyroid stimulating hormone and normal total thyroxine hyperthyroid? Usefulness of 99mTc pertechnetate uptake.

The records of 107 patients who had had thyroid 99m Tc pertechnetate uptake measured, were reviewed. In patients with normal serum thyroxine (T4) and thyroid stimulating hormone (TSH), 35 of 36 with normal uptake and three with high uptake were clinically euthyroid. In patients with high serum T4 and low TSH, seven had normal and 29 had high uptake and all were clinically hyperthyroid. In patients with normal serum T4 and low TSH, 10 of 11 with high uptake were clinically hyperthyroid whereas only two of 18 with normal uptake were. The sensitivity, specificity and positive predictive value of pertechnetate uptake measurements were 83%, 94%, and 91%, respectively. The measurement of pertechnetate uptake is a rapid investigation and may help in the interpretation of patients with undetectable serum TSH found in the presence of normal serum T4.

Comparison of ventilation/perfusion lung-imaging and dead-space measurements in airway disease.

1. Nineteen patients (three normal subjects, at 16 patients with chronic airway disease) were investigated with radionuclide lung-imaging and pulmonary function tests. 2. There was a statistically significant correlation between the ratio of residual volume to total lung capacity and alveolar dead-space ventilation for nitrogen as a percentage of alveolar ventilation (an index of gas mixing inefficiency); rs = 0.54, P less than 0.05. 3. There were statistically significant associations between an abnormal ventilation or perfusion radionuclide lung image and (a) the ratio of residual volume to total lung capacity and (b) the alveolar dead-space ventilation for nitrogen as a percentage of alveolar ventilation. 4. The radionuclide counts from the posterior images were normalized for lung size and injected dose; perfusion counts were then subtracted from ventilation counts at locations from the top to the bottom of the lungs. 5. There was a statistically significant association between low ventilation minus perfusion areas and arterial hypoxia. 6. There was a statistically significant association between high ventilation minus perfusion areas and an increased alveolar dead-space ventilation for carbon dioxide as a percentage of alveolar ventilation.

Health care-seeking practices of pregnant women and the role of the midwife in Cape Town, South Africa.

The objective of this study was to investigate the health-seeking practices of pregnant women in a periurban area in Cape Town, South Africa. This qualitative study was based on 103 minimally structured in-depth interviews of 32 pregnant women. Most women were interviewed on several occasions, and a group discussion was held with women. The interviews were taped, transcribed, analyzed ethnographically, and, if necessary, translated into English. Antenatal care attendance was influenced by a number of factors, including women's knowledge of the role of antenatal care, perceived health needs, booking systems, nurse-patient relationships, economics, child care, and transport. The expected benefits were weighed against the anticipated costs before decisions about seeking care were made. The findings highlight the importance of women's perceptions of quality of care in influencing their health seeking practices. The study suggests that considerably more attention needs to be given to this aspect of maternity services.
