Comparative StudySingle-dose versus multi-dose vaccine vials for immunization programmes in developing countries.
Excessive vaccine wastage and safety concerns have prompted the international health community to develop and supply vaccines in formats other than the standard multi-dose vial. This article presents a programmatic and economic comparison of the major differences between the multi-dose vials and single-dose formats used for immunization services in developing countries. Multi-dose vials, in general, sell at a lower per-dose price and occupy less cold-chain capacity than single-dose formats. ⋯ However, multi-dose vials are likely to be most appropriate for cheaper vaccines and in settings where cold-chain storage capacity is restricted. Single-dose formats will be most appropriate for more expensive vaccines and where there are problems with unsafe injection practices. Prefilled AD injection devices will be particularly useful in expanding outreach services while eliminating the possibility of needle reuse.

Review Comparative StudyA new face for private providers in developing countries: what implications for public health?
The use of private health care providers in low- and middle-income countries (LMICs) is widespread and is the subject of considerable debate. We review here a new model of private primary care provision emerging in South Africa, in which commercial companies provide standardized primary care services at relatively low cost. The structure and operation of one such company is described, and features of service delivery are compared with the most probable alternatives: a private general practitioner or a public sector clinic. ⋯ Encouraging such providers to compete for government funding could, however, be desirable if the range of services presently offered, and those able to access them, could be broadened. However, the constraints to implementing such a system successfully are notable, and these are acknowledged. Even without such contractual arrangements, these companies provide an important lesson to the public sector that acceptability of services to users and low-cost service delivery are not incompatible objectives.

Antipyretics, including acetaminophen (paracetamol), are prescribed commonly in children with pyrexia, despite minimal evidence of a clinical benefit. A literature review was performed by searching Medline and the Cochrane databases for research papers on the efficacy of paracetamol in febrile illnesses in children and adverse outcomes related to the use of paracetamol. No studies showed any clear benefit for the use of paracetamol in therapeutic doses in febrile children with viral or bacterial infections or with malaria. ⋯ No evidence shows that it is beneficial to treat febrile children with paracetamol. Treatment should be given only to children who are in obvious discomfort and those with conditions known to be painful. The role of paracetamol in children with severe malaria or sepsis and in malnourished, febrile children needs to be clarified.

Randomized Controlled Trial Clinical TrialImplementation and quantitative evaluation of chronic disease self-management programme in Shanghai, China: randomized controlled trial.
To evaluate the effectiveness of the Shanghai Chronic Disease Self-Management Program (CDSMP). ⋯ When implemented in Shanghai, the CDSMP was acceptable culturally to Chinese patients. The programme improved participants' health behaviour, self-efficacy, and health status and reduced the number of hospitalizations six months after the course. The locally based delivery model was integrated into the routine of community government organizations and community health services. Chinese lay leaders taught the CDSMP courses as successfully as professionals.
