Cutaneous leucocytoclastic vasculitis associated with omeprazole.

Omeprazole is a potent proton pump inhibitor and usually is well tolerated. Adverse effects of this drug have been reported in up to 5% of patients, most of which are trivial and disappear rapidly on discontinuation of the drug. Skin adverse reactions attributed to omeprazole are uncommon and include rashes, urticaria, angio-oedema, acute disseminated epidermal necrolysis, lichen spinulosus, and contact dermatitis. Cutaneous leucocytoclastic vasculitis (CLV) has not been previously reported in association with omeprazole. The development of CLV in an elderly patient four weeks after starting treatment with omeprazole is described.

Syndrome packets and health worker training improve sexually transmitted disease case management in rural South Africa: randomized controlled trial.

BACKGROUND: Sexually transmitted diseases (STD) are important co-factors in HIV transmission. We studied the impact of health worker training and STD syndrome packets (containing recommended drugs, condoms, partner notification cards and information leaflets) on the quality of STD case management in primary care clinics in rural South Africa. METHODS: A randomized controlled trial of five matched pairs of clinics compared the intervention with routine syndromic management. Outcomes were measured by simulated patients using standardized scripts, and included the proportion given recommended drugs; correctly case managed (given recommended drugs plus condoms and partner cards); adequately counselled; reporting good staff attitude; and consulted in privacy. RESULTS: At baseline, the quality of STD case management was similarly poor in both groups. Only 36 and 46% of simulated patients visiting intervention and control clinics, respectively, were given recommended drugs. After the intervention, intervention clinics provided better case management than controls: 88 versus 50% (P < 0.01) received recommended drugs; 83 versus 12% (P < 0.005) were correctly case managed; 68 versus 46% (P = 0.06) were adequately counselled; 84 versus 58% experienced good staff attitude (P = 0.07); and 92 versus 86% (P = 0.4) were consulted privately. A syndrome packet cost US$1.50; the incremental cost was US$6.80. The total intervention cost equalled 0.3% of annual district health expenditure. INTERPRETATION: A simple and affordable health service intervention achieved substantial improvements in STD case management. Although this is a critical component of STD control and can reduce HIV transmission, community-level interventions to influence health-seeking behaviour are also needed.

Barriers to implementing South Africa's Termination of Pregnancy Act in rural KwaZulu/Natal.

INTRODUCTION: South Africa's Termination of Pregnancy Act, the most liberal abortion law in Africa, took effect early in 1997. In spite of the anticipated benefits to women's health, however, public reaction has been mixed. In the country's most populous province, KwaZulu/Natal, opposition is strong and most health care providers have refused to provide the service. This study explored attitudes and beliefs about abortion and the Termination of Pregnancy Act among primary care nurses and community members in a rural district in order to better understand barriers to implementation of the new law. METHODS: As part of a community survey on women's reproductive health (n = 138), questions on knowledge, attitudes and beliefs about abortion were asked, as well as awareness of the provisions of the Termination of Pregnancy Act. To better understand the perspectives of health care workers, a survey among primary care nurses on duty (n = 25) was also conducted. In-depth interviews were conducted with both nurses and women in the community to further pursue issues raised in the two surveys. RESULTS: Support for the Act was low (11%) among both community members and nurses, and few supported abortion on request (18 and 6%, respectively). Within each group, however, a clear hierarchy of support was observed: a majority of nurses (56%) and community members (58%) supported abortion in the case of rape or incest, or if the continued pregnancy would endanger a woman's health (61 and 56%, respectively), but few supported abortion for social or economic reasons. In-depth interviews revealed that abortion is seen as contrary to prevailing community norms; nurses were poorly informed about the Termination of Pregnancy Act and felt confused in their professional responsibilities. CONCLUSIONS AND RECOMMENDATIONS: Legalization alone cannot ensure implementation of abortion services. In South Africa, extensive media coverage prior to passage of the law ensured almost universal awareness of the Act, but little public education took place at the same time. In spite of general opposition to the law, however, there is an encouraging level of support for abortion in some circumstances. These findings suggest that abortion services can be implemented, even in conservative rural areas, but that a process of information dissemination and community consent prior to implementation is essential. Locating abortion within broader reproductive health services could be an effective way to improve access and acceptability.

STD syndrome packets: improving syndromic management of sexually transmitted diseases in developing countries.

OBJECTIVE: To design, introduce, and evaluate "STD syndrome packets" containing recommended drugs for each syndrome, four condoms, a partner treatment card, and a patient information leaflet, with the goal of improving sexually transmitted disease (STD) case management. METHODS: Packet design evolved around available packaging technology, informed by pilot testing with nurses working in primary care clinics, doctors in private medical practices, and patients with an STD, in Hlabisa, South Africa. Evaluation 1 year later included analysis of distribution records and interviews with 16 nurses and 64 patients. RESULTS: A cheap packet (2 U. S. cents each, excluding contents) compatible with current legislation was designed and introduced to six public sector clinics and as a short pilot to five private medical practices. Four thousand eighty-five packets were distributed to the clinics, equivalent to approximately 115% of the STDs reported over that period. All 16 nurses reported using the packets, but only 63% did so all the time because of occasional supply problems. All believed the packets improved treatment by saving time (75%), improving supply of condoms and partner cards (44%), and making treatment easier (56%). Patients also responded positively, and most said they would buy a packet (up to $5) at a pharmacy (84%) or store (63%) if available. CONCLUSIONS: The STD syndrome packets have the potential to improve STD syndromic management by standardizing therapy and improving the supply of condoms, partner cards, and information leaflets. Packets are popular with practitioners and patients, but consistent supply is essential for maximal impact. There may be scope for social marketing of the packets, which could further increase use.

Inadequate treatment for sexually transmitted diseases in the South African private health sector.

Correct management of sexually transmitted diseases (STDs) is important for their control, and to reduce HIV transmission. Guidelines on syndromic management of STDs were introduced by the provincial Department of Health in KwaZulu/Natal (KZN) in South Africa in 1995. The drug treatment provided for STDs by the 11 private general practitioners in one rural district was assessed and compared with provincial guidelines. Information was gathered through semistructured interviews which asked the 11 doctors, who all dispense prescribed drugs as part of the consultation fee, how they would treat 3 hypothetical cases of STD syndromes. In all 33 prescriptions, the treatment did not correspond exactly with provincial recommendations and only 3 (9%) were adequate. All other prescriptions were inadequate because dose or duration was incorrect in 6 (18%), or because incorrect drugs were prescribed in 24 (73%) of cases. Eight of the 11 doctors did not provide adequate treatment for any of their cases. A continuing medical education programme for the doctors and their staff was devised to improve the STD treatment in the private sector in this South African district.

Unrecognized sexually transmitted infections in rural South African women: a hidden epidemic.

Sexually transmitted infections (STIs) are of major public health concern in developing countries, not least because they facilitate transmission of human immunodeficiency virus (HIV). The present article presents estimates of the prevalence, on any given day, of STIs among women in rural South Africa and the proportion who are asymptomatic, symptomatic but not seeking care, and symptomatic and seeking care. The following data sources from Hlabisa district were used: clinical surveillance for STI syndromes treated in health facilities, microbiological studies among women attending antenatal and family planning clinics, and a community survey. Population census provided denominator data. Adequacy of drug treatment was determined through quality of care surveys. Of 55,974 women aged 15-49 years, a total of 13,943 (24.9%) were infected on any given day with at least one of Trichomonas vaginalis, Neisseria gonorrhoeae, Chlamydia trachomatis, or Treponema pallidum. Of the women investigated, 6697 (48%) were asymptomatic, 6994 (50%) were symptomatic but not seeking care, 238 (1.7%) were symptomatic and would seek care, and 14 (0.3%) were seeking care on that day. Only 9 of the 14 women (65%) were adequately treated. STIs remained untreated because either women were asymptomatic or the symptoms were not recognized and acted upon. Improved case management alone is therefore unlikely to have a major public health impact. Improving partner treatment and women's awareness of symptoms is essential, while the potential of mass STI treatment needs to be explored.

Traditional healers as tuberculosis treatment supervisors: precedent and potential.

SETTING: Hlabisa, South Africa. OBJECTIVE: To determine precedent and potential for traditional healers to act as tuberculosis (TB) treatment supervisors. METHODS: Literature review to describe precedent for the involvement of traditional healers in TB treatment supervision. Interviews with 100 TB patients to determine use of healers and their acceptability as supervisors. Interviews with 24 healers in the project sub-district to determine willingness to act as supervisors. RESULTS: Despite extensive literature on the interaction between traditional healers and conventional health services, including descriptions of traditional understandings of TB, no published work was identified that reported supervision of TB patients by traditional healers. Of 100 patients interviewed, only 10% had used a healer as the first health provider for their illness, but 40% had attended a healer at some time prior to diagnosis. Although only 4% believe healers can cure TB, 84% would consider choosing a healer as a treatment supervisor. Of the 24 healers, 15 (63%) distinguished between two types of diagnosis made among patients with symptoms suggestive of TB: TB and idliso. Idliso is poisoning or bewitching, and is said to be best cured by healers, while TB is infectious and cannot be cured by healers. Most healers (88%) reported having referred patients with possible TB to hospital in the past; all were keen to negotiate collaboration with health services, and 92% were willing to act as treatment supervisors. CONCLUSIONS: While there is little reported precedent for traditional healers to interact formally with tuberculosis treatment services, the potential for collaboration seems to be high, at least in our setting.

Improving quality of sexually transmitted disease case management in rural South Africa.

OBJECTIVE: To measure quality of sexually transmitted disease (STD) syndromic case management and aspects of health-seeking behaviour at baseline in an intervention trial. SETTING: Ten rural primary care clinics, Hlabisa district, South Africa. DESIGN: Simulated patients (fieldworkers trained to present with STD syndromes) made a total of 44 clinic visits; 49 STD patients were interviewed when exiting clinics; facilities were assessed for availability of necessary equipment and drugs; 10 focus group discussions were held with staff; and STD syndrome surveillance was performed in all 10 clinics. RESULTS: A total of 9% of simulated patients were correctly managed (given correct drugs, plus condoms and partner notification cards), recommended drug treatment was given in only 41% of visits, and appropriate counselling was given in 48% of visits. Among patients leaving the clinic, although 39% waited over an hour to be seen and only 37% were consulted in private, all reported staff attitudes as satisfactory or good. Only six clinics had syndromic management protocols available, three reported intermittent drug shortages, and seven lacked partner notification cards. Focus group discussions revealed good staff knowledge about STD, but showed lack of training in syndromic management and low morale. Surveillance data showed that while 75% of those presenting for care did so within 1 week of symptom onset, 27% had been treated for an STD in the preceding 3 months, and only 6% of those treated were contacts. CONCLUSIONS: Quality of STD case management was poor despite good staff knowledge and availability of most essential resources. An intervention comprising staff training and STD syndrome packets has been designed to improve quality of case management.

Sexually transmitted disease syndromes in rural South Africa. Results from health facility surveillance.

BACKGROUND AND OBJECTIVE: Surveillance for sexually transmitted diseases (STD) is important for priority setting, service development, and evaluating interventions. GOAL: To conduct health facility-based surveillance for STDs to inform design of a control program and to provide baseline measures for evaluation of interventions. STUDY DESIGN: Surveillance system for patients with STD syndromes in public and private sector health facilities in Hlabisa, South Africa. RESULTS: Over a 5-month period, 4,781 patients with an STD were reported, 3,126 (65%) by clinics and 1,655 (35%) by general practitioners; 2,582 (54%) were in men. Most were diagnosed with a single syndrome. Discharge was most common (49% of both male and female patients), followed by ulcer (36% of men and 14% of women). Mean symptom duration was 18 days for women and 10 days for men (p < 0.0001). A quarter reported having another STD in the previous 3 months. The highest age-specific incidence was estimated at 16.4% among women 20 to 24 years of age. CONCLUSIONS: The burden of STDs is high in rural South Africa. There is considerable scope for improved disease control, and the private sector has an important role to play.

Targeted intervention research studies on sexually transmitted diseases (STD): methodology, selected findings and implications for STD service delivery and communications.

OBJECTIVE: To report the findings of qualitative studies designed for use in improving sexually transmitted disease (STD) programs. The studies explore illness conceptions and treatment behaviors for STD in five African countries. These targeted intervention research (TIR) studies were performed on clinic-based and community-based samples in representative communities and utilized a variety of qualitative research methods (e.g. in-depth and key informant interviews, focus group discussions). FINDINGS: Study findings revealed that community members' explanations of symptoms, classification of illnesses, and perceptions of whether symptoms are pathological or serious influence individual health-care-seeking behaviors. Data also showed that local terms for STD are often disparaging and do not fit into biomedical designations. STD patient care-seeking frequently reflects an ordered, albeit loosely constructed, process of elimination in pursuit of symptom relief, wherein alternative treatments are tried and proven effective or abandoned. CONCLUSIONS: The TIR studies highlight the importance of community-specific strategies aimed at increasing prompt care seeking at qualified biomedical facilities. Information from study data should lead programs to sensitize health professionals to community understanding about STD and to design services and communication programs that are meaningful and appropriate to local contexts.

Mode of c-myc protein expression in Spitz nevi, common melanocytic nevi and malignant melanomas.

The expression of c-myc protein was studied in formalin-fixed, paraffin-embedded sections of 16 compound Spitz nevi (SNs), 20 ordinary compound melanocytic nevi (MNs) and 30 malignant melanomas (MMs), using monoclonal antibody 9E10 and an immunoperoxidase technique. Nine (56%) SNs, 16 (80%) MNs and 23 (77%) MMs showed positive reactions in some of the tumor cells (P = non-significant). The staining reactions were mostly cytoplasmic, and moderate to strong in intensity. The frequencies of positively stained cells were higher in the MN and SN groups. Most of the lesions with a significant dermal component did not show stratification of staining with progressive descent into the dermis. Therefore, the mode of expression of c-myc in routinely processed specimens does not differentiate between SNs, MNs and MMs. One possible reason is that the increased expression of the c-myc protein is not sufficient alone to promote proliferation and malignant transformation in these types of tumors.

Family planning services in developing countries: an opportunity to treat asymptomatic and unrecognised genital tract infections?

OBJECTIVE: To determine the prevalence of asymptomatic and unrecognised genital tract infections among women attending a family planning clinic in rural South Africa. METHODS: 189 consecutive women had genital samples taken to diagnose infection with Neisseria gonorrhoeae, Chlamydia trachomatis, Trichomonas vaginalis, Candida albicans, Treponema pallidum, and HIV, and to diagnose bacterial vaginosis. RESULTS: Mean age was 25 years; 155 (82%) were unmarried, 156 (83%) were currently using contraception, and 41 (22%) reported having an STD treated in the preceding 12 months. Although none volunteered abnormal urogenital symptoms, 74 (39%) had at least one elicited by direct questioning. 119 women (63%) had at least one genital infection: N gonorrhoeae (eight; 4%), C trachomatis (14; 8%), T vaginalis (26; 14%), C albicans (56; 30%), active syphilis (15; 8%), HIV (44; 24%), and bacterial vaginosis (29; 15%). 49 women (26%) had multiple infections. Most infections (71; 60%) were asymptomatic. Symptomatic women failed to recognise and report their symptoms, and routine services failed to detect the infections. CONCLUSION: Prevalence of genital tract infection is high among these women, most infections are asymptomatic, and symptomatic infections are frequently not recognised. Women attending family planning clinics in such settings should be screened for syphilis and offered testing for HIV infection. Strategies to detect and treat other genital infections need to be developed.

Synchronous and metachronous contralateral adrenal metastases from primary renal cell carcinoma.

Two rare cases of contralateral adrenal metastases are reported. One with a synchronous presentation where the renal tumor was removed together with a solitary large contralateral adrenal metastasis. The second patient underwent adrenalectomy for a metastatic lesion diagnosed 4 years after nephrectomy performed for renal cell carcinoma of the contralateral kidney. Five years following the adrenalectomy the patient underwent leg amputation because of a solitary bone metastasis.

Incidence of long-term sick-listing in an urban area of Sweden and its relationship with demographic data of the population.

By checking the card indexes of seven out of twelve Social Insurance Offices covering 66% of the total wage-earning population in the city of Göteborg the patients recorded for 90 days of continuous sick-listing were classified into four diagnostic categories according to the doctor's certificate: "non-specific pain" and "specific pain" of the musculoskeletal system, "other pain" and "non-pain" diagnoses. The overall yearly incidence of 90 days' sick-listing averaged 5.4%. A significant correlation was found between the incidence of 90 days' sick-listing due to "non-pain" and musculoskeletal pain diagnoses and the proportion of demographic characteristics of the areas. The hypothesis of presuming the highest association between non-specific pain diagnoses and demographic factors was rejected.

Exploring partner communication and patterns of sexual networking: qualitative research to improve management of sexually transmitted diseases.

This ethnographic research among rural South African men and women seeking care for STDs explores constraints to communication among partners and defines predominant patterns of sexual networking. A series of fifteen open-ended interviews explored topics related to sexual networking and partner communication. Patterns of sexual networking showed clear gender variation, with men more likely to discuss multiple partners. Both men and women believed they should tell one partner about their STD, most often a steady partner. Strong distinctions were made between regular and casual partners, with an emphasis on the role of trust in a steady relationship. Men and women expressed anxiety about telling their partners of their illness, but women more often expressed fear whereas men felt embarrassed. Multi-partnered sexuality is common and is widely accepted for men. While the importance of regular partnerships is clear for both men and women, sexual relationships appear to be highly unstable. Communication among partners could be facilitated by stronger health promotion messages, such as the importance of telling a partner about an STD. Prevailing patterns of communication and sexual networking have profound implications for the STD epidemic.
