    Opis:
    This study was undertaken to assess the pulmonary and respiratory problems of workers in a zarda factory. A total of 70 permanent zarda workers (50 manufacturing workers and 20 office ones) were studied in a factory in Baguihati, Kolkata, India. The study included (a) completion of a questionnaire (on pulmonary and respiratory problems), (b) measurement of physical parameters, (c) spirometry and (d) measurement of peak expiratory flow rate. At the same time, the worksite was analyzed with an OSHA-recommended ergonomics checklist. Many zarda manufacturing workers complained of respiratory symptoms. Continuous exposure to the tobacco processing environment reduced the workers lung volume and peak expiratory flow rates. Our study indicates that zarda manufacturing workers may have respiratory and pulmonary disorders related to exposure to tobacco dust in their work environment.

    Opis:
    Objectives: The aim of this study was to verify and analyze the existence of chronic adaptations of lung function in freediving fishermen whose occupation is artisanal fishing. Material and Methods: This was a cross-sectional study involving 11 breath-hold diving fishermen and 10 non-breath-hold diving fishermen (control) from the village of Bitupitá in the municipality of Barroquinha (Ceará - Brazil). Anthropometric measurements, chest and abdominal circumferences as well as spirometric and respiratory muscle strength tests were conducted according to the specifications of the American Thoracic Society/European Respiratory Society (ATS/ERS). In order to compare the measured values versus the predicted values, Student t test was used in the case of parametric test and Wilcoxon test in the case of nonparametric test. To compare the inter-group means Student t test was used for parametric test and Mann-Whitney test for the nonparametric one. The level of significance was set at α = 5%. Results: The forced vital capacity (FVC) (4.9±0.6 l vs. 4.3±0.4 l) and forced expiratory volume in 1 s (FEV₁) (4.0±0.5 l vs. 3.6±0.3 l) were, respectively, higher in the group of divers compared to the control group (p ≤ 0.05). Furthermore, in the group of free divers, the measured FVC, FEV₁ and FEV₁/FVC ratios were significantly greater than the predicted ones. No differences were found between the measured respiratory pressures. Conclusions: These results indicate that breath-hold diving seems to produce chronic adaptations of the respiratory system, resulting in elevated lung volumes with no airway obstruction.

    Opis:
    Introduction. In India, obesity is rapidly escalating in all age groups. Obesity has significant effects on respiratory function and reduces lung volume. Peak Expiratory Flow Rate (PEFR) demonstrates the calibre of the airways and is accepted worldwide as the objective indicator of ventilatory capacity, and is useful for the diagnosis and management of respiratory illness. Objective. The aim of this study was to compare the Peak Expiratory Flow Rates between obese and non-obese females aged 35–45. Materials and method. 40 healthy obese females with BMI ≥30Kg/m2 and 40 healthy non-obese females with BMI (18.5– 24.9 Kg/m2) as controls were included in the study. Subjects with H/o cardiopulmonary illness, asthma, diabetes mellitus, hypertension, smokers, on chronic medication, subjects who had noticeable weight gain / loss over the preceding 3 months, were all excluded. PEFR Measurements were performed using a Mini Wright’s Peak Flow Meter. Three readings at 2 minutes intervals were recorded. The maximum of the 3 values were taken as the PEFR. The results were statistically analysed using Students Unpaired t- test. Results. PEFR in obese females (320±28.06 L/Min) was significantly lower than the non-obese females (361±29.17L/Min), which was statistically significant (p=0.000; p<0.05). PEFR was negatively correlated with BMI (Pearson’s correlation r = -.127) significant at p<0.01 level. Conclusions. There occurs a significant reduction in PEFR in obese females, compared to non-obese females. This study highlights the need for aggressive reduction of weight in obese females in order to increase respiratory efficiency.

    Opis:
    Background: Jute industry workers constantly exposed themselves to jute dust and are at risk of impairment of lung function. Investigation on various studies revealed the effects of exposure to jute dust but limited studies so far undertaken regarding its bearing on pulmonary function of jute workers of West Bengal,India. Purpose: To evaluate the respiratory status of jute mill workers of West Bengal exposed to occupational hazards. Materials and Methods: This cross sectional study was conducted on 203 male jute mill workers of age range 18 – 60 yrs. from West Bengal and a control group of 141 men of similar age .Dynamic pulmonary function parameters were carried out including physical parameters, respiratory abnormalities, year of exposure and smoking history. Results: FVC, FEV1, FEF 200-1200 and PEFR values of higher age group non smoker of low dust zone were significantly higher in comparison to the non smoker of high dust zone. The prevalence of chest tightness was 33.49% and liver dysfunction was 41.9% in dusty zone workers of jute mill in comparison to less dusty zone. Again, incidence of chest tightness and cough was highest (35.44%) in higher age group workers and prevalence of byssinosis like symptoms and chronic bronchitis was 30- 37% after 10 – 30years of exposure. But occurrence of bronchial asthma was 11.9% in workers of greater than 20 years of exposure. Prevalence of all the above respiratory abnormalities was higher among smokers than non-smokers. Conclusions: Concentration of jute dust exposure had been associated with decrease in FVC, FEV1, and PEFR with a higher risk of developing chronic bronchitis, bronchial asthma, byssinosis and other respiratory symptoms. This indicated high occupational health hazards which would create an alarming situation, if remained unchecked.

    Objectives: To explore the rate of pneumoconiosis in dental technicians (DTP) and to evaluate the risk factors. Material and Methods: Data of 893 dental technicians, who were admitted to our hospital in the period January 2007–May 2012, from 170 dental laboratories were retrospectively examined. Demographic data, respiratory symptoms, smoking status, work duration, working fields, exposure to sandblasting, physical examination findings, chest radiographs, pulmonary function tests and high-resolution computed tomography results were evaluated. Results: Dental technicians’ pneumoconiosis rate was 10.1% among 893 cases. The disease was more common among males and in those exposed to sandblasting who had 77-fold higher risk of DTP. The highest profusion subcategory was 3/+ (according to the International Labour Organization (ILO) 2011 standards) and the large opacity rate was 13.3%. Conclusions: To the best of our knowledge, it was the largest DTP case series (N = 893/90) in the literature in English. Health screenings should be performed regularly for the early diagnosis of pneumoconiosis, which is an important occupational disease for dental technicians.

    Background The respiratory system is the most vulnerable system in the cement industry. This study was conducted to determine the effects of occupational exposure to cement dust on the respiratory system more thoroughly. Material and Methods In this cross sectional study an interviewer-administered questionnaire on socio-demographic characteristics and respiratory symptoms was completed and pulmonary function tests were carried out on 100 exposed and 120 non-exposed workers at the cement factory in Mashhad, Iran. The data was statistically analyzed by SPSS 16. Results The mean of age and work duration in the exposed group was 37.5±6.3 and 10.7±5.4 years compared with the non-exposed group that was 36.1±7.1 and 10.1±5.7 years, respectively. Levels of exposure to inhalable cement dust in the exposed group were 23.13 mg/m³ (higher than national occupational exposure limits for such particles). Among the exposed group, respiratory symptoms as cough (6% vs. 0.8% of the non-exposed) and sputum (7% vs. 0.8% of the nonexposed) were significantly more prevalent (p < 0.05). Forced expiratory flow 25–75% (FEF25–75%) was significantly lower in the exposed workers compared with non-exposed ones (p < 0.05). Also forced expiratory volume in 1 s / forced vital capacity (FEV₁/FVC) and FEF25–75% had a reverse correlation with the length of employment (p = 0.000 and p = 0.003, respectively). Conclusions The findings of this study showed that occupational exposure to cement dust could be a significant factor of respiratory system dysfunction. Strict implementation of a respiratory protection program is recommended in cement industries. Med Pr 2015;66(4):471–477
    Wstęp Układ oddechowy jest tym najbardziej narażonym w przypadku pracy w przemyśle cementowym. Poniższe badanie miało na celu precyzyjne określenie wpływu na układ oddechowy narażenia zawodowego na pył cementowy. Materiał i metody W ramach analizy przekrojowej 100 narażonych oraz 120 nienarażonych na pył pracowników fabryki cementu w Mashhad w Iranie wypełniło kwestionariusz na temat cech społeczno-demograficznych oraz objawów oddechowych, a także poddało się testom wydolności płuc. Otrzymane dane zostały przeanalizowane statystycznie za pomocą SPSS 16. Wyniki Średnia wieku oraz czas zatrudnienia dla grupy badanej wyniosły odpowiednio 37,5±6,3 roku oraz 10,7±5,4 roku, a dla grupy porównawczej 36,1±7,1 roku oraz 10,1±5,7 roku. Poziom narażenia na działanie wdychanego pyłu cementowego w grupie badanej wyniósł 23,13 mg/m³ i przekraczał dozwoloną krajową normę narażenia zawodowego na te cząstki. W grupie badanej takie objawy oddechowe, jak kaszel (6% vs 0,8% w grupie porównawczej) i plwocina (7% vs 0,8%) znacznie przeważały nad innymi (p < 0,05). Wymuszony przepływ wydechowy 25–75% (FEF25–75%) odnotowano na znacznie niższym poziomie w przypadku narażonych pracowników w porównaniu do tych nienarażonych (p < 0,05). Także stosunek natężonej objętości wydechowej pierwszosekundowej do natężonej pojemności życiowej (FEV₁/FVC) oraz FEF25–75% wskazywały na odwrotną korelację z długością zatrudnienia (odpowiednio: p = 0,000 i p = 0,003). Wnioski Narażenie zawodowe na pył cementowy może być ważnym czynnikiem powodującym dysfunkcję układu oddechowego. Ścisłe przestrzeganie programu ochrony układu oddechowego jest zalecane w przemyśle cementowym. Med. Pr. 2015;66(4):471–477
