On 6 May 1995, the Médecins sans Frontières (MSF) coordinator in Kinshasa, Democratic Republic of the Congo (DRC), received a request for assistance for what was believed to be a concurrent outbreak of bacillary dysentery and viral hemorrhagic fever (suspected Ebola hemorrhagic fever [EHF]) in the town of Kikwit, DRC. On 11 May, the MSF intervention team assessed Kikwit General Hospital. This initial assessment revealed a nonfunctional isolation ward for suspected EHF cases; a lack of water and electricity; no waste disposal system; and no protective gear for medical staff. The priorities set by MSF were to establish a functional isolation ward to deal with EHF and to distribute protective supplies to individuals who were involved with patient care. Before the intervention, 67 health workers contracted EHF; after the initiation of control measures, just 3 cases were reported among health staff and none among Red Cross volunteers involved in body burial.
Doris Schopper and colleagues describe the functioning of the Médecins Sans Frontières independent ethics review board and the framework used for ethics review, and discuss challenging ethical issues encountered by the board since its inception.
Summarybackground In many countries including South Africa, the increasing human immunodeficiency virus (HIV) and tuberculosis (TB) epidemics have impacted significantly on already weakened public health services. This paper reviews the scope, process and performance of the HIV and TB services in a primary care setting where antiretroviral therapy is provided, in Khayelitsha, South Africa, in order to assess whether there is a need for some form of integration.methods The scope and process of both services were assessed through observations of the service and individual and group interviews with key persons. The performance was assessed by examining the 2001-2002 reports from the health information system and clinical data.results The TB service is programme oriented to the attainment of an 85% cure rate amongst smearpositive patients while the HIV service has a more holistic approach to the patient with HIV. The TB service is part of a well-established programme that is highly standardized. The HIV service is in the pilot phase. There is a heavy load at both services and there is large degree of cross-referral between the two services. There are lessons that can be learnt from each service. There is an overlap of activities, duplication of services and under-utilization of staff. There are missed opportunities for TB and HIV prevention, diagnosis and management.conclusions The study suggests that there may be benefits to integrating HIV and TB services. Constraints to this process are discussed.
Standard short course chemotherapy is recommended by the World Health Organization to control tuberculosis worldwide. However, in settings with high drug resistance, first line standard regimens are linked with high treatment failure. We evaluated treatment outcomes after standardized chemotherapy with the WHO recommended category II retreatment regimen in a prison with a high prevalence of drug resistant tuberculosis (TB). A cohort of 233 culture positive TB patients was followed through smear microscopy, culture, drug susceptibility testing and DNA fingerprinting at baseline, after 3 months and at the end of treatment. Overall 172 patients (74%) became culture negative, while 43 (18%) remained positive at the end of treatment. Among those 43 cases, 58% of failures were determined to be due to treatment with an inadequate drug regimen and 42% to either an initial mixed infection or re-infection while under treatment. Overall, drug resistance amplification during treatment occurred in 3.4% of the patient cohort. This study demonstrates that treatment failure is linked to initial drug resistance, that amplification of drug resistance occurs, and that mixed infection and re-infection during standard treatment contribute to treatment failure in confined settings with high prevalence of drug resistance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
