    ABSTRACT: Farming is a large and main industry in Bangladesh. Large numbers of people are directly involved in farming and have very unique exposure compare to other sectors. Musculoskeletal problems among farmer population are not infrequent. This study was carried out among 200 farmers in one selected district. The study revealed that musculoskeletal problems were common among the farmers working in a traditional way. All the respondents were male. The age of all respondents lie between 20-60 years. Among them 22.5% farmers were illiterate, about 45.5% below Class V. About half (42%) of the respondents had reported pain in different parts of the body at least one or more times during working in land. And about two third (65.5%) of the farmers had history of joint pain and stiffness in last 12 month. Most of the farmers who suffered from musculoskeletal symptoms were 41-60 years. Specially who worked more then 20 years (82.6%) and average 6 hours per day (66.7%). The occurrence of musculoskeletal problems in various part of the body included Knee pain - 48.1%, Back pain (back ache) - 22.9%, Waist pain (low back ache) - 13.3%, Neck pain - 18.3% and shoulder pain - 10.7%. Length of work in year and daily average working hours were found significant association with musculoskeletal pain. It was found that musculoskeletal pain were more common among the farmers when they worked in squatting position (52%) and specially during weeding of plants (31%). Among them only 22% also engaged in other business. Most of the farmers complained dull aching pain (40.6%), only 2.3% noticed severe acute pain, but about 86% farmers' temporary stop their work for pain and 80% get relief after discontinue of work. About 75% respondents visited doctors for their pain which was statistically significant (p=0.001). It was found that the rates of musculoskeletal complaints are more among those individuals who worked relatively bad ergonomic condition, such as body position probably play an important role.

    ABSTRACT: Climate change is taking its toll in the form of saline water intrusion into the mainland of Bangladesh, which is one of the lowest-altitude countries in the world. The study was carried out with the objective to assess the blood pressure status associated with salinity in saline prone selected areas of Bagherhat and Tangail districts from March 2008 - June 2008 of rural Bangladesh. Two hundred and ninety subjects were selected purposively from both the districts. About 70% of the respondents were males and below forty years of age. More than two thirds of the respondents were illiterate; belong to 4-5 member family, with monthly family income of less than Tk. 4000 per month. Only one third of the respondents were smokers. More than two thirds of the respondents from salinity area had salinity level of 2-3%. Among them majority were drinking saline water for 6-10 years and 26% were drinking for more than ten years. About 20% of the non saline respondents' systolic blood pressure was 110-120 mm of Hg and 26% of saline area had systolic blood pressure >135-140 mm of Hg. Mean systolic BP among salinity area was more than that for non salinity area. About 19% of the non saline respondents' diastolic blood pressure was ≤85 mm of Hg. About one third had ≥90 mm of Hg, among them 31% were from saline area. Mean diastolic BP among salinity area was more than non salinity area. There was no history of heart disease, and less than 1% was diabetic among them. About two thirds had mean arterial pressure <70 mm of Hg, among them majority were from non saline area. About one third had >70 mm of Hg, among them majority were from saline area. The study concluded that systolic and diastolic blood pressures of saline group were significantly higher than that of the non saline group.

    ABSTRACT: The objective of this cross-sectional comparative study was to assess quality of life (QOL) of arsenicosis patients. A total of 104 arsenicosis patients, 104 arsenic-exposed individuals without arsenicosis (nonpatients), and 104 individuals not exposed to arsenic (controls) were interviewed based on a questionnaire constructed based on the WHOQOL-BREF instrument. The facets of life considered for assessing QOL were physical health domain, psychological domain, social relationships domain, and environment domain. All the domain-wise QOL scores of the arsenicosis patients were significantly smaller than those of the controls as well as of the nonpatients. The findings of the study assessing QOL of arsenicosis patients might be helpful to understand the condition and justify for the policy makers to adopt adequate measures to alleviate the sufferings through prevention, treatment, and rehabilitation.

    ABSTRACT: This cross-sectional study was carried out in some selected arsenic contaminated rural areas of Bangladesh to determine any clinical changes in oral cavity, among the arsenic exposed population through drinking water. Total 600 respondents (200 arsenicosis patients, 200 non-patients but having the history of taking arsenic contaminated water and another 200 arsenic non-exposed). 75.5% of arsenicosis patients had swelled vallate papillae whereas only 44.5% and 8.5% in case of arsenic exposure and non-exposure subjects respectively. The differences were found statistically significant (p < 0.001). This study suggests that there is a tendency of developing swelled vallate papillae among the arsenic exposed population.

    ABSTRACT: ABSTRACT Objective: The aim of this study was to explore the respiratory problems among the workers working in a Poly bag manufacturing industry Materials and Methods: This was a cross-sectional study carried out among 99 Poly bag manufacturing workers. Data was collected through face to face interview of the respondents by using a pre-tested questionnaire. Peak Flow Meter was used to measure the Peak Expiratory Flow Rate of the workers. Place and period of study: The study was conducted during April to June 2007 in a Poly bag manufacturing industry situated in Narayangonj. Results: Among the total 99 workers, majority (78.8%) were male. Most (59.6%) of the workers were working in this industry for less than 3 years. The age of the workers ranged from 16 to 25 years and the mean age was 26.2 ± 7.67years. It was observed that 86.2% of the workers were working without using any PPE. Of the total respondents 68.8% of the workers were found to be suffering from respiratory problems. The respiratory problems suffered by them were running nose (40.4%), cough (55.5%) and respiratory distress (30.3%) such as chest tightness and shortness of breath. The peak expiratory flow rate of the workers ranged from 200 L/min to 650 L/min and the mean was 342.32 L/min. The PEFR was found to be significantly (t=-2.793; p=.006) low among the workers who were suffering from respiratory problems compared to that of workers who were not suffering from such problems. Conclusion: The study concludes that the respiratory problems such as running nose, cough, and chest tightness and shortness of breath with decreased PEFR were prevalent among the Poly bag manufacturing workers. These respiratory problems are reported to be attributable to exposure to polypropylene which is a main raw material for manufacturing Poly bag. JOPSOM 2008; 27(1): 60-68

    ABSTRACT: A cross-sectional survey was conducted in Matlab, Bangladesh, to determine the prevalence of skin lesions (a three-step procedure) associated with arsenic exposure and discuss validity and feasibility in relation to recommended screening algorithms. Cases with skin lesions were identified by screening above 4 years of age (n = 166,934). Trained field teams conducted a careful house-to-house screening and identified 1682 individuals with skin lesions, who were referred to physicians for confirmation. Physicians diagnosed 579 cases as probable and documented all these with digital photographs. Two experts inspected all photographs for consensus agreement that was reached for 504 cases. Using the experts' opinions as reference, the positive predictive value of the physicians' diagnosis was 87% (male = 82% vs. female = 94%; p < 0.01). The physicians had difficulties in separating arsenic-induced keratosis from differential diagnoses, while probability for correct diagnosis was high for arsenic-related pigmentation changes. Including information on current arsenic concentration in drinking water (which was masked at time of skin examination) or urine in the diagnostic algorithm should have increased the number of false negative cases. In the present transition of drinking water sources these markers of current exposure levels provide no information on past exposure. A 2-3 step procedure with house-to-house screening and clinic-based confirmation of arsenic-induced skin lesions is a feasible approach. Information on arsenic concentration in current water sources or in urine should not have improved the precision in the diagnosis. These results may have policy implications for community screening of arsenic-related skin lesions in Bangladesh and elsewhere.

    ABSTRACT: This study was carried out among arsenic-exposed and non-exposed people of Bangladesh to assess and compare their cardiac status based on electrocardiographic (ECG) findings. For the purpose of the study, participants were included in three groups: arsenic-exposed persons with arsenicosis (arsenicosis group), arsenic-exposed persons without arsenicosis (non-arsenicosis group), and persons not exposed to arsenic (non-exposed group). Each group included 50 respondents. In this study, no significant difference in heart rate, rhythm, axis, and pulse rate interval was detected among the arsenicosis, non-arsenicosis and non-exposed groups. A significant difference in corrected QT interval between the arsenicosis and the non-exposed group (p<0.05) was observed. On the contrary, no statistically significant difference in corrected QT interval between the non-arsenicosis and the non-exposed group was found. Abnormal QRS complex was found among 14%, 8%, and 2% of the arsenicosis, non-arsenicosis, and non-exposed groups respectively. ECG findings, indicative of left ventricular hypertrophy, ischaemic heart disease, and right bundle branch block, were high among the arsenicosis group. Overall, abnormal ECG findings were high (58%) among the respondents of the arsenicosis group and were highly significant (p<0.001). The findings revealed that there was a significant association between ECG abnormalities and arsenic exposure.

    ABSTRACT: This study was carried out in two arsenic-affected villages of Bangladesh to explore the relationship between total arsenic in urine and the severity of disease manifestations. A total of 60 subjects consisting of 30 cases and 30 controls were included in the study. The mean ages of cases and controls were 32.97 (± 7.65) and 32.7 (± 7.6) years, respectively. The arsenic content of the tubewell water consumed by the cases and the controls ranged from 100 to 1000 ppb and from 0 to 40 ppb, respectively. The total arsenic content in the urine of the cases and the controls ranged from 62–332 ppb and from 0–55 ppb, respectively. The difference in mean urinary levels of total arsenic between the cases (163.8 ppb) and the controls (10.7 ppb) was statistically significant (p < 0.001). Cases with grade-2 lesions (15) were consuming water containing higher levels of arsenic (526.7 ppb) compared to cases with grade-1 lesions (403.3 ppb), but the difference was not statistically significant. Statistically significant differences (< 0.001) in duration of tubewell water use, age of skin lesion and total arsenic in urine between cases with grade-1 and grade-2 manifestations were observed. Positive correlations (p < 0.001) were observed between arsenic load (estimated) and total arsenic in urine, age of the skin lesion and severity of disease manifestation.

    ABSTRACT: This paper, firstly, shows the distribution of arsenic-contaminated groundwater in Samta village. This village, which is in Jessore district in Bangladesh, was chosen as a model village for investigating the mechanism of groundwater contamination. 90% of the tube wells in this village had arsenic concentrations above the Bangladesh standard of 0.05 mg/l. Tube wells with arsenic concentrations of over 0.50 mg/l were distributed in the southern part of the village with a belt-like shape from east to west. Secondly, groundwater distribution is discussed with respect to its flow and the high arsenic zone (As≥0.50 mg/l) agrees well with the drifting zone of the groundwater. Furthermore, arsenic-free water supply systems suitable for a small area in the village have been developed. A pond sand filter (PSF) system which purifies pond water is discussed in this paper. Prior to the construction of the PSF, the water quality in ponds was examined for arsenic levels. The inflow of drainage from the tube wells was found to be the major cause of arsenic contamination of pond water. The PSF installed in Samta is working very well and produces a good quality of treated water.

    ABSTRACT: Arsenic contamination in ground water and its toxic effect on human health is a recent public health problem in Bangladesh. So far 44 districts were found affected with arsenic contamination in ground water. Among these 44 districts, arsenicosis cases were identified in 26 districts. A total of 1625 cases were detected from 133 villages in 157 thanas of these districts. The majority (90%) of the cases were detected in the rural areas. It is estimated that about 35 million people in Bangladesh are at risk of arsenic toxicity. All the three stages of manifestations of chronic arsenicosis were observed in Bangladesh. But majority of patients were found in initial and second stage. Among the arsenicosis patients the common manifestations were melanosis, keratosis, hyperkeratosis and depigmentation (Leukomelanosis). So far there is no specific treatment of such chronic arsenic toxicity in human health. Mild cases have shown to be improved by withdrawing further intake of arsenic contaminated water. Symptoms are improved by taking protein rich diet and vitamin A, E & C at initial and second stages of toxicity. Recently chelating agent Penicillamine has been used in selected cases for the treatment of arsenicosis. People of the affected and high-risk areas are advised to use arsenic safe water to prevent health hazards. Indexing words: Arsenic contamination, Arsenicosis, Ground water

    ABSTRACT: Lung function of weaving workers were assessed by measuring Peak Expiratory Flow Rate (PEFR) with Wright’s Peak Flow Meter in 410 workers: 210 from a cotton mill and 200 from a jute mill. Both the exposed and non-exposed workers were included in the study. The mean PEFR of the workers was 469.7 L/min and it was comparatively low among the exposed workers of the both the mills. The PEFR values were found to correlate highly (p<0.001) with age, length of occupation and number of cigarette smoking and there were negative linear relationship. With height and chest expansibility, the PEFR had positive linear relationship. But with weight the PEFR had curvilinear relationship. The workers who had respiratory diseases had significantly low PEFR value (406.75 L/min)
