Musculoskeletal symptoms, skin disorders and visual impairment among fishermen in the Divisional Secretariat Division of Kalpitiya.

INTRODUCTION: To describe musculoskeletal symptoms, skin disorders and visual impairment among fishermen in the Divisional Secretariat Division of Kalpitiya. METHODS: This was a community based descriptive cross sectional study conducted from August to October 2011. The sample consisted of 465 fishermen with ≥ 6 months experience in fishing selected using the cluster sampling technique. An interviewer administered questionnaire and a record sheet were used for data collection. Prevalence of the above conditions with 95% confidence Intervals (CI) were calculated. Chi square test was applied for the investigation of the factors associated with the above conditions. RESULTS: The prevalence of musculoskeletal symptoms was 61% (95% CI: 56.6%-65.4%). The commonest symptom was back pain (37.6%). The prevalence of skin disorders was 24% (95% CI: 20.1-27.8) and visual symptoms were 38.9% (95% CI: 34.5%-43.3%). The prevalence of visual impairment of either eye was 24.3% (95% CI: 20.3%- 28.3%) low vision of either eye 22.4% (95% CI: 18.6%- 26.2%) and blindness of either eye was 1.9% (95% CI: 1.1-2.7). The prevalence of visual impairment of better eye was 16% (95% CI: 12.7-19.3), low vision of better eye 15% (95% CI: 12-18.3) and blindness of better eye were 0.9% (95% CI: 0.05-1.75). The prevalence of musculoskeletal symptoms, skin disorders or visual impairment did not vary according to service duration in the fishing industry, number of days spent in the boat for a trip or type of boat. CONCLUSIONS: Prevalence of musculoskeletal and skin disorders and visual impairment were relatively higher among the fishermen.

Blood sugar lowering effect of Coccinia grandis (L.) J. Voigt: path for a new drug for diabetes mellitus.

BACKGROUND: Role of herbs in the management and control of diabetes has emerged fast over the years. We assessed the efficacy of Coccinia grandis (locally known as Ken, Kovakka) leaves as a hypoglycemic agent. METHODS: Double-blind phase I clinical trial was conducted at the general hospital and a private hospital in Matara in August 2009. All the participants were given a common meal for dinner, and they maintained a 10-hour fasting period. Sixty-one healthy volunteers were given a meal containing 20 g of leaves of Coccinia grandis which was mixed with a measured amount of scraped coconut and table salt for breakfast, and other 61 were given the placebo meal which also contained scraped coconut and salt. Glucose tolerance test was performed blindly for the two groups. Mixed factorial design analysis of variance and student's t-test were applied. RESULTS: Overall blood sugar levels of the experimental group were also significantly lower than those of the control group (F(1,117) 5.56, P < 0.05). Increase in the blood sugar levels from fasting to one hour (F(1,117) 6.77, P < 0.05) and two hours (F(1,117) 5.28, P < 0.05) postprandially was statistically significant for participants who were in the control group than those of in the experimental group. The mean difference of postprandial blood sugar levels (mg/dL) after one hour (20.2, 95% confidence interval, 4.81 to 35.5) and two hours (11.46, 95% confidence interval; 1.03 to 21.9) was statistically significant between the two groups. CONCLUSIONS: Coccinia grandis has a blood sugar lowering effect. However further studies are needed to validate our findings.

How have we been managing chronic obstructive pulmonary disease in Australia?

AIM: Although chronic obstructive pulmonary disease (COPD) is a main cause of disability, hospital admissions and premature deaths in Australia, little is known about the community management of COPD in relation to recently published guidelines. The aim of the article was to report on COPD management in a community based cohort. METHODS: A random sample of adults aged between 45 and 70 years drawn from the electoral roll participated in the study. They completed a detailed respiratory questionnaire, spirometry, methacholine challenge and measurement of transfer factor. COPD was defined according to the Global initiative for Chronic Obstructive Lung Disease (GOLD) criteria. Current asthma was defined as wheeze during the last 12 months together with bronchial hyperreactivity. Subjects were classified as either COPD-only, asthma-only or both asthma and COPD. RESULTS: Of 1224 subjects completing spirometry, 39 (3.5%) met the GOLD criteria for stage 2 or 3 COPD, asthma-only was found in 99 (8.9%) subjects and 40 (3.6%) subjects had both asthma and COPD. The COPD-only group was significantly older than the other two groups. More than 40% of subjects with COPD did not have a diagnosis of COPD from their doctors. Only 48.7% of subjects with COPD had ever been prescribed medication for their breathing. More than two-thirds of all subjects had seen a doctor for breathing problems, but very few had seen a general practitioner in the last 12 months and even fewer had respiratory function tests. CONCLUSIONS: Most subjects with COPD are being undertreated. Diagnosis, monitoring and referral systems should be improved. Preventive activities such as influenza vaccination and smoking cessation should be intensified.
