“…14 The present study showed the mean age of the steel weaving factory workers was 31.10 years within the age group of 25-55 years as shown in Table1. The result was found to be consistent with the studies that Bhutan, Thailand belong to the age group of 31-40 years [17][18][19]. The workers of the steel weaving factorywork in 8 hours shift duration.…”

Introduction: Excessive noise exposure is one of the majorly considered occupational stress for industrial workers. The operation of steel weaving machinery producing a high level of noise such as weaving machines, crimping machines, and hydraulic press machines for a prolonged period increases the risk of developing noise-induced hearing loss (NIHL). The main aim of the study was to assess the auditory health of the workers exposed to a high level of noise in a steel weaving factory and the prevalence of NIHL among workers. Methods: 26 subjects in the age group of 25-55 years from a steel weaving industry of Chinsurah town, Hooghly district of West Bengal were randomly selected with 5 years of exposure for the study. The control group was selected from the same age group, socioeconomic status and geographical location and having no history of such exposure. The physiological parameters of the workers, noise levels in the workplace and auditory functions and the risk of NIHL were assessed by standardized protocol and statistically analyzed. Results: The study indicated that steel weaving factory workers had significantly reduced hearing functionality at 4000Hz and 6000Hz in the left ear respectively. It also revealed that the workers were exposed to high noise exposure of 131dB near weaving machine, 113dB at crimping machine, and 84dB at hydraulic press machine respectively. Conclusion: A high level of noise exposure leads to deterioration in the hearing capabilities of the steel weaving industrial workers. Implementation of ergonomic interventions in the workplace and the use of personal protective equipment (PPE) may decrease the prevalence of NIHL and can help to prevent hearing loss in workers.

“…The prevalence, 41.6% of hearing loss in this study, it's found that more than half (50.7%) of the industrial workers are suffering from hearing impairment either due to ONIHL or other types of hearing impairments. Which was higher than 34% found the studies conducted in Ethiopia, 30.86% in Turkey, 38% found in India, 33.46% in Bangladesh, 30% in Jordan, 35% in Canada and 27.9% in Bhutan 13,16,17,19,[21][22][23] . These differences of hearing loss may have resulted from the use of hearing loss prevention programs for all workers whose unprotected 8-hr TWA exposures equal or exceed 85 dB(A) with assessment of noise exposure and audiometric monitoring.…”

Exposure to any type of noise has a potential risk. Higher the level of noise and longer duration of exposure, more the risk for hearing sensitivity and health as a whole. Occupational noise induced hearing loss (ONIHL) is a major cause of disability throughout the world. So this study was designed to know the prevalence of NIHL among the noise exposed industrial workers in Bangladesh. A prospective observational study of 377 People working at industrial environment in Jute mills at Faridpur region were studied between January 2021 to June 2021. Data collected from each respondent recorded on a predesigned data collection form. Pure tone audiometry was performed in both ears. Among 377 study population, 157(41.6%) subjects had hearing loss and 220 subjects (58.4%) had no loss. Among the workers with hearing loss, 98(62.4%) got hearing loss on both sides, 32(20.4%) on the right side and 27(17.2%) on the left side. Among them 83(52.9%) had mild hearing loss, 37(23.6%) had moderate hearing loss, 31(19.7%) had severe hearing loss and 6(3.8%) had profound hearing loss. The average duration of work in the industry was 6.94±5.64 years and majority (78.5%) had 8 hours working hour per day and 21.5% had more than 8 hours. The average sound intensity was 91.51±8.12 dB(A) with 10.9% exposed to <_85 dB(A) and 89.1% to >85 dB(A). This study shows Noise-induced hearing loss (NIHL)as highly prevalent among noise-exposed workers in Bangladesh. Age >35 years, high noise level, exposure of more than 10 years, were significantly associated with increased risk of hearing loss. The local and national authority should focus on noise monitoring, engineering modifications of buildings and machinery, occupational safety policies, administrative controls, providing education on NIHL, periodic audiometric assessments and follow-up evaluation for hearing threshold shift. This study supported the elements for further research studies related to the employer compliance with occupational health and safety regulations to address awareness of their responsibility in minimizing hazards in workplaces.

Acute poisoning is common in Bangladesh and causes a significant number of hospital admissions. That causes anumber of mortality, morbidity as well as increases the economic burden in health care system. But it can beprevented. For that it is necessary to observe and study the poisoning related factors and events around the country.So, the aim of our study is to find out and describe the mode, pattern and precipitating factors of poisoning in asouthern district hospital. This cross-sectional observational study was done in the department of Medicine ofPirojpur District Hospital, from January to December 2020. The study was conducted among 100 patients of bothgenders those were hospitalized with the history of poisoning. In the study young people (40% in 14-25 years and37% in 26-35 years) were predominantly affected and 61% were female. Suicidal attempt was the commonest(74;74%) mode of poisoning that mostly caused by pesticides. Stupefying mode was observed in case of 15(15%)male travelers as street poisoning. Highest number of poisoning (45;45%) was caused by pesticides. The sedative(14;14%), copper sulphate (11;11%) and harpic (5;5%) poisoning was observed mostly as a suicidal mode. Historyof savlon (4;4%) and Kerosene (2;2%) poisoning was found as an accidental mode. As a recreational mode two malewere admitted with alcohol poisoning. Considering the precipitating factor, maximum cases (54;54%) had the historyof unsatisfactory family events. Street poisoning (15;15%) was precipitated by the careless behavior of travelers.Accidental poisoning (9,9%) was invited by unmindful and hurried attitude. Problem related to love and affair wasobserved in 8(8%) cases. Study and examination result precipitated poisoning in 7(7%) cases. History of job andincome dissatisfaction was found in 4(4%) cases. So those factors related with the poisoning should be considered.That will help to make a comprehensive strategy in order to resist these preventable events. Bangabandhu Sheikh Mujib Med. Coll.
