Panabokke CR. Statistical methods Data were analysed using statistical package for social sciences SPSS version The survey was designed to sample a population distributed equally among the nine provinces of the country. We conducted a population-based, cross-sectional study in an agricultural community to describe the chronic musculoskeletal disabilities of snake envenoming. Within each district, the required number of clusters was selected by simple random sampling from the list maintained by the Department of Census and Statistics, Sri Lanka. There was a positive association with elevation up to meters above sea level, with incidence dropping at higher elevations. Published online Jul 8.
However, the main outcome of interest, a snakebite, is highly memorable and we think it unlikely that this affects our estimates although the possibility of the incidence of envenoming being increased due to inappropriate classification of envenomed bites is acknowledged. A Population-Based Study. A biopsy of the ulcer done during this study excluded malignant transformation while skeletal and soft tissue imaging excluded chronic osteomyelitis. November 4, Table 2.
Of the 8, residents recruited into the study, have had a snakebite at least once during their lifetime.
Incredible snaps show crocodile and snake thrashing about as they battle to the death in Sri Lanka
The paucity of reliable data is partly related to inherent methodological difficulties, which include: Agricultural work has commonly been identified as a risk factor for snakebite. National Center for Biotechnology InformationU. Giorgi E, Diggle Peter J. Trop Doct. Conceived and designed the experiments:
Mapping the Risk of Snakebite in Sri Lanka - A National Survey with Geospatial Analysis
Model-based geostatistics was used to develop snakebite risk maps for Sri Lanka. This article is published under license to BioMed Central Ltd. In conclusion, this study provides population-based data in a neglected area of research to suggest that snakebite envenoming is associated with considerable chronic musculoskeletal disabilities. Snake envenoming has been reported to lead to a variety of musculoskeletal disorders such as amputation of limbs or digits, Volkmann contracture, joint stiffness, arthritis, disseminated osteomyelitis, chronic ulceration with malignant transformation, Raynaud phenomenon and loss of muscle mass [ 12 — 16 ].
