A worm was extracted from the subconjunctival space of the left eye in a 14-year old Sri Lankan girl, who returned to Sri Lanka in 1983 after spending six years in Nigeria. It was identified as a male Loa loa. A history of evanescent (Calabar) swellings was obtained. She also had significant eosinophilia. Microfilariae were not detected in the blood. This is the first case of Loa loa infection reported from Sri Lanka. 相似文献

Harm reduction in the developing world 总被引:1,自引:0,他引:1
Samarasinghe D 《Drug and alcohol review》1995,14(3):305-309
This paper examines harm reduction from the perspective of poor countries. In considering which elements of the broad approach are suitable for adaptation and adoption by poor countries, there is a need to examine critically the arguments put forth in support of it and which, if any, of these are supported by evidence. There are also significant indirect influences that the approach is likely to have on how drug use is understood and interpreted by wider society. The likely impact of these on areas other than simply services directed to drug users needs to be assessed. There are some features regarding harm caused by alcohol and other drug use that are specific to poor countries. Most important among these is that levels of use which are not deemed to be harmful in rich societies cause grave harm through diverting meagre resources away from survival needs in the poor world. Alcohol, as well as other drugs, tends in deprived settings to cause dependence and other problems much earlier in people's drinking careers and at much lower levels of consumption than in rich countries. 相似文献
