Is there a divide between local medicinal knowledge and Western medicine? a case study among native Amazonians in Bolivia

Background: Interest in ethnomedicine has grown in the last decades, with much research focusing on how local medicinal knowledge can contribute to Western medicine. Researchers have emphasized the divide between practices used by local medical practitioners and Western doctors. However, researchers have also suggested that merging concepts and practices from local medicinal knowledge and Western science have the potential to improve public health and support medical independence of local people. In this article we study the relations between local and Western medicinal knowledge within a native Amazonian population, the Tsimane'. Methods: We used the following methods: 1) participant observation and semi-structured interviews to gather background information, 2) free-listing and pile-sorting to assess whether Tsimane' integrate local medicinal knowledge and Western medicine at the conceptual level, 3) surveys to assess to what extent Tsimane' combine local medicinal knowledge with Western medicine in actual treatments, and 4) a participatory workshop to assess the willingness of Tsimane' and Western medical specialists to cooperate with each other. Results: We found that when asked about medical treatments, Tsimane' do not include Western treatments in their lists, however on their daily practices, Tsimane' do use Western treatments in combination with ethnomedical treatments. We also found that Tsimane' healers and Western doctors express willingness to cooperate with each other and to promote synergy between local and Western medical systems. Conclusion: Our findings contrast with previous research emphasizing the divide between local medical practitioners and Western doctors and suggests that cooperation between both health systems might be possible

Effective Rheology of Bubbles Moving in a Capillary Tube

We calculate the average volumetric flux versus pressure drop of bubbles moving in a single capillary tube with varying diameter, finding a square-root relation from mapping the flow equations onto that of a driven overdamped pendulum. The calculation is based on a derivation of the equation of motion of a bubble train from considering the capillary forces and the entropy production associated with the viscous flow. We also calculate the configurational probability of the positions of the bubbles.Comment: 4 pages, 1 figur

Health burden and economic impact of measles-related hospitalizations in Italy in 2002–2003

Background: A large measles outbreak occurred in Italy in 2002 - 2003. This study evaluates the health burden and economic impact of measles- related hospitalizations in Italy during the specified period. Methods: Hospital discharge abstract data for measles hospitalizations in Italy during 2002 - 2003 were analysed to obtain information regarding number and rates of measles hospitalizations by geographical area and age group, length of hospital stay, and complications. Hospitalization costs were estimated on the basis of Diagnosis- Related Groups. Results: A total of 5,154 hospitalizations were identified, 3,478 ( 67%) of which occurred in children < 15 years of age. Most hospitalizations occurred in southern Italy ( 71 %) and children below 1 year of age presented the greatest hospitalization rates ( 46.2/ 100,000 and 19.0/ 100,000, respectively in 2002 and 2003). Pneumonia was diagnosed in 594 cases ( 11.5%) and encephalitis in 138 cases ( 2.7%). Total hospital charges were approximately (sic) 8.8 million. Conclusion: The nationwide health burden associated with measles during the 2002 - 2003 outbreak was substantial and a high cost was incurred by the Italian National Health Service for the thousands of measles- related hospitalizations which occurred. By assuming that hospital costs represent 40 - 50% of the direct costs of measles cases, direct costs of measles for the two years combined were estimated to be between (sic)17.6 - 22.0 million, which equates to the vaccination of 1.5 - 1.9 million children ( 3 - 4 birth cohorts) with one dose of MMR. The high cost of measles and the severity of its complications fully justify the commitment required to reach measles elimination
