Knowledge, attitude, and practice of sugarcane crushers towards hand injury prevention strategies in India.

INTRODUCTION: Injuries of the hand have an enormous impact on hand function and on quality of life. Occupational injuries are a major cause of morbidity and mortality in India and their incidence has been steadily increasing. Sugarcane crushers produce juice using dangerous procedures. OBJECTIVE: The objective of this study was to determine the knowledge, attitudes, and practices among sugarcane crushers in India and thus assist in the formulation of effective preventive strategies. SETTING: A block (area) in the Vellore District, South India (population 100 000). SUBJECTS AND METHODS: All sugarcane crushers living in this area (n = 32) were included. A single observer, using a questionnaire, conducted personal on-site interviews. RESULTS: Carelessness was involved in 63% of injuries. Sixteen per cent felt that machines with improved safety features are required; 40% supported the use of special gloves, although 19% considered them a hindrance. Eighty eight per cent did not consider the long duration of work as a risk factor and 38% were fatalistic (God's will); 50% thought the injuries were due to "bad luck". CONCLUSION: Sugarcane crushers do not perceive the need for safer equipment. To overcome fatalistic views, and persuade this group to take other safety measures, safety education will need to take into consideration their socioeconomic and educational status.

Antimicrobial activity of extracts of eastern North American hardwood trees and relation to traditional medicine.

Wood and bark extracts of 14 eastern North American hardwood tree species which were used traditionally as medicine by First Nation's people were screened for antimicrobial activities with eight strains of bacteria and six strains of fungi. Eighty-six percent of the bark extracts were active against methicillin sensitive Staphylococcus aureus; 71% against Bacillus subtilus and 79% against Mycobacterium phlei. The bark extract of Juglans cinerea was active against Pseudomonas aeruginosa 187, Salmonella typhiumurium, and Klebsiella pneumoniae. The wood extracts were less active: 72% were active against S. aureus (methicillin-sensitive), 36% against B. subtilus and 43% against M. phlei. Results from antifungal tests indicated that 36% of the extracts were active against at least one fungal strain and that bark extracts were more active than wood extracts. The bark extract from Juglans cinerea had the broadest spectrum of activities against Candida albicans, Saccharomyces cerevisiae, Cryptococcus neoformans, Trichophyton mentagrophytes, Microsporum gypseum, and Aspergillus fumigatus. In general, the extracts were more active against gram positive bacteria than gram negative bacteria and against filamentous fungi than yeast-like fungi. The study also demonstrated a correlation between frequency of traditional medicinal use by the First Nations people and antimicrobial activity of extracts indicating that the traditional knowledge encompasses an understanding of aspects of chemical ecology.

Effects of single and repeated electroconvulsive therapy sessions on plasma ACTH, prolactin, growth hormone and cortisol concentrations.

To study the effects of electroconvulsive therapy (ECT) on hormone release, we measured circulating concentrations of adrenocorticotropic hormone (ACTH), prolactin (PRL), growth hormone (GH) and cortisol (CORT) immediately before and at 2 min, 5 min, 15 min, and 30 min following ECT. Compared to pre-ECT concentrations, there were significant increases in post-ECT plasma ACTH, PRL and CORT. GH did not change consistently. No significant difference between unilateral and bilateral ECT was observed. Compared to the first ECT, repeated treatments were associated with a significant decrease in the magnitude of hormone surge. These hormonal changes induced by ECT may reflect changes at the neurotransmitter level.
