Background and Aims Inhalation of respirable silica dust during several stone processing methods can result in several respiratory diseases. However, data are scarce regarding the respiratory health of stone‐cutting workers in Bangladesh. We aimed to determine the point prevalence of respiratory symptoms, lung function status and radiological abnormalities among the stone‐cutting workers. Methods This cross‐sectional study was conducted among 200 stone‐cutting workers. Adult workers having a job experience of at least 3 years participated in this study. Then inquiry was made regarding respiratory symptoms with the help of a preformed questionnaire. All the participants underwent chest X‐ray and spirometry. A respiratory dust sampler was used to measure the dust concentration of the stone‐cutting factories. Results Among the 200 stone‐cutting workers, 89% (178) showed at least one chronic respiratory symptom while they had chest tightness (75.5%), chronic cough (74.5%), and shortness of breath (66.5%) as the most prominent ones. Spirometry findings revealed that the mean forced expiratory volume in 1 s (FEV 1 ) value was 1.42± 0.65 L in the obstructive pattern, 1.43 ± 0.73 L in the restrictive pattern. The mean forced vital capacity (FVC) value was 2.53 ± 1.12 L in the obstructive pattern, 1.53 ± 0.75 L in the restrictive pattern. 42.69% of stone‐cutting workers who complained of at least one respiratory symptom had abnormal chest X‐ray findings. Those with progressive massive fibrosis had the lowest mean FEV 1 value (0.75 ± 0.50 L). While measuring workplace dust concentration, we found high particulate matter (PM) 2.5 (979.78 µg/m 3 ) and PM 10 (1298.35 µg/m 3 ) values. Conclusions Most of the stone‐cutting workers in our study exhibited different respiratory symptoms. These symptoms were associated with abnormal lung function and radiology. Further longitudinal studies are recommended to determine the actual dimension of this problem.
Multiple myeloma is a malignant proliferation of plasma cells that typically presents in the bone marrow.Extramedullaryplasmacytoma (EMP) represents an unusual and characteristically progressive malignancythat can arise outside the bone marrow. The occurrence of multiple myeloma with plasmacytoma of thelung is very unusual. Herein, we report a case of multiple myeloma with plasmacytoma of the lungdiagnosed by CT-guided FNAC and bone marrow trephine biopsy. J MEDICINE 2022; 23: 96-100
This cross-sectional study was conducted to determine the serum lipid profiles in chronic obstructive pulmonary disease (COPD) patients and its correlation with the severity of COPD in the Department of Respiratory Medicine at Bangabandhu Sheikh Mujib Medical University. A total of 100 spirometric-confirmed cases of COPD were included. Fasting blood samples for lipid profiles were collected. To identify the association between severity of COPD with lipid profiles Pearson’s correlation was used. Further multiple linear regression was done to identify the relation. The mean (standard deviation) age of the patients was 59.0 (10.7)years. The ratio of males and females was 19:1. The mean forced expiratory volume (liters) in 1 second (FEV1) was 55.1 (18.1). Most of the patients had stage II (48%) and stage III (36%) airflow obstruction. Plasma level of total cholesterol and triglyceride tend to increase, statistically non-significant, with stages of COPD. However, the association of plasma lipids becomes statistically significant with FEV1 when the effects of age, BMI, pack-year smoking, duration of illness are accounted in multiple linear regression analysis.

Background and Aims Rice mill workers are frequently exposed to rice dust specks containing bacteria, endotoxins, spores, and chemicals in workplaces. Consequently, they develop diverse respiratory symptoms that lead to increased disability and social burden. The present study was conducted to observe the frequency of respiratory symptoms among rice mill workers in Bangladesh. Methods This cross‐sectional study was conducted at different rice mills in Rangpur district of Bangladesh. Three hundred and forty‐six rice mill workers, both male and female of 18 years and above, with a job experience of at least 3 years, were selected as study subjects. An equal number of people who had never worked at rice mills were selected from the nearby locality as the nonexposed group. Enquiries were made regarding respiratory symptoms with the help of a preformed questionnaire which contained sociodemographic characteristics, occupational history, potential confounding factors, and physical parameters. A respiratory dust sampler was used to measure workplace dust concentration. Results The presence of one or more respiratory symptoms was significantly higher among rice mill workers than in the nonexposed group (52.3% vs. 17.6%). Rice mill workers who worked for more than 10 h and had a working experience of more than 15 years had a higher frequency of respiratory symptoms (41.3% and 39.8%, respectively). Rice mill workers with body mass index (BMI) <18.5 also exhibited more respiratory symptoms (25.4%). All working sections had a higher‐than‐average dust concentration level, with the milling section being the dustiest (PM 2.5 492.1 µg/m 3 ). Conclusion This study showed an increased frequency of respiratory symptoms among rice mill workers of Bangladesh. Longer working experience and working hours, low BMI and high dust concentration levels were strongly associated with that increase in frequency.
