Air pollution from household solid fuel combustion in India: an overview of exposure and health related information to inform health research priorities

Environmental and occupational risk factors contribute to nearly 40% of the national burden of disease in India, with air pollution in the indoor and outdoor environment ranking amongst leading risk factors. It is now recognized that the health burden from air pollution exposures that primarily occur in the rural indoors, from pollutants released during the incomplete combustion of solid fuels in households, may rival or even exceed the burden attributable to urban outdoor exposures. Few environmental epidemiological efforts have been devoted to this setting, however. We provide an overview of important available information on exposures and health effects related to household solid fuel use in India, with a view to inform health research priorities for household air pollution and facilitate being able to address air pollution within an integrated rural–urban framework in the future

Mentoring in complex surgery: minimising the learning curve complications from peri-acetabular osteotomy

PurposeThe aim of this study was to determine whether a complex surgical procedure such as peri-acetabular osteotomy could be safely learnt by using a programme involving mentoring by a distant expert. To determine this, we examined the incidence of intra-operative complications, the acetabulum correction achieved, the late incidence of re-operation and progressive degenerative arthritis.MethodsBetween 1992 and 2004, peri-acetabular osteotomy was performed in 26 hips in 23 patients. The median follow-up was ten (5-17) years. The median age of the patients at operation was 28 (14-41) years. Clinical outcomes were reported and radiographic results were determined by an independent expert.ResultsThere were no intra-articular osteotomies, sciatic nerve injuries, hingeing deformities or vascular injuries. There was one ischial nonunion. The lateral centre-edge angle improved from a median 4° pre-operatively to 25°. One revision osteotomy, one osteectomy and three total hip replacements were required, two for progression of osteoarthritis.ConclusionsThe programme of mentoring was successful in that there was a low incidence of the major intra-operative complications that are often reported during the learning curve period and the acetabular corrections achieved were similar to the originators.Donald W.
