ABSTRACT

Objective: To understand the incidence of pneumoconiosis in the non-coal mining industry in Jiangsu Province, and provide reference for the prevention and control of pneumoconiosis in the non-coal mining industry. Methods: The data of 7019 newly diagnosed pneumoconiosis patients in non-coal mining industry in Jiangsu Province from January 1956 to December 2019 were collected through the Jiangsu Province Pneumoconiosis Follow-up Network Report System, including the gender of the pneumoconiosis patients, the name of the employer and the location, the industry classification of the employer, the duration of dust exposure in dust exposure, the name of occupational pneumoconiosis disease, the date of diagnosis of pneumoconiosis, etc. The collected case data of patients with pneumoconiosis were entered into the statistical software, and the characteristics of the patients' diagnosis time, region and industry were analyzed. Results: The number of confirmed pneumoconiosis patients in the non-coal mining industry in Jiangsu Province was mostly in 2007 (395 cases) , concentrated in Wuxi City (40.96%, 2875/7019) and Suzhou City (27.72%, 1946/7019) . The industries to which the patients belonged were mainly non-metallic mining and dressing (60.95%, 4278/7019) , and the most common type of pneumoconiosis was silicosis (96.40%, 6766/7019) . The patients were mainly stageⅠpneumoconiosis (61.33%, 4305/7019) . There were statistically significant differences in the mean age of diagnosis and the average duration of dust exposure among patients with different pneumoconiosis stages (P<0.01) . The differences in the average diagnosis age and the average duration of dust exposure of patients with different types of pneumoconiosis were statistically significant (P<0.05) , the mean age of diagnosis and the average duration of dust exposure of electric welders were the smallest, which were (44.92±7.74) years old and (17.38±10.15) years, respectively. Conclusion: The regional and industry distribution characteristics of new pneumoconiosis patients in the non-coal mining industry in Jiangsu Province are obvious, and attention should be paid to the treatment of pneumoconiosis patients with young diagnosed age and short duration of dust exposure, as well as the personal protection and health protection of front-line workers such as electric welders who are exposed to productive dust in a short period of time.

ABSTRACT

Objective: To understand the incidence of pneumoconiosis in Ningbo city from 1967 to 2019, and to analyze the distribution characteristics and change trend of pneumoconiosis. Methods: In February 2021, the data of pneumoconiosis patients in Ningbo city from 1967 to 2019 were sorted out. The data from 1967 to 1987 were from historical case files of Zhejiang Center for Disease Control and Prevention, the data from 1988 to 2005 were from the historical case files of Ningbo Center for Disease Control and Prevention, and the data from 2006 to 2019 were from the pneumoconiosis report card in China Disease Prevention and Control Information System; Followed up and supplement relevant information, including basic information, basic information of employers and information related to pneumoconiosis diagnosis, and comprehensively analyze the composition and development trend, population characteristics and industry characteristics of pneumoconiosis. Results: From 1967 to 2019, a total of 1715 cases of pneumoconiosis were reported in Ningbo City, including 1254 cases of stageⅠpneumoconiosis, 258 cases of stageⅡpneumoconiosis, 172 cases of stage Ⅲpneumoconiosis. 1202 cases of silicosis (70.09%) , 296 cases of asbestosis (17.26%) , 40 cases of welder's pneumoconiosis (2.33%) , 32 cases of graphite pneumoconiosis (1.87%) were reported. There were 1296 male cases (75.57%) and 419 female cases (24.43%) were reported. Silicosis (91.15%, 1102/1209) and welder's pneumoconiosis (100.00%, 40/40) were the most common pneumoconiosis in males, while asbestosis (90.24%, 268/297) and graphite pneumoconiosis (87.50%, 28/32) were the most common pneumoconiosis in females. The average age was (49.71±10.90) years old and the average length of service was (10.98±6.96) years. The top three reported pneumoconiosis cases were construction industry (336 cases, 19.59%) , ferrous metal smelting and rolling industry (317 cases, 18.48%) and non-metallic mineral products industry (315 cases, 18.37%) . The top three reported pneumoconiosis cases were 414 cases (24.14%) in Ninghai County, 294 cases (17.14%) in Yuyao City and 272 cases (15.86%) in Yinzhou District. Conclusion: With the development of industries in Ningbo City, government departments should strengthen supervision and management of enterprises involving silica dust and welding fume to curb the high incidence of pneumoconiosis.

ABSTRACT

Objective: To understand the survival status and its influencing factors of occupational pneumoconiosis patients in Shizuishan City, and to analyze the disease burden of occupational pneumoconiosis and its trend, so as to provide scientific basis for formulating comprehensive prevention and treatment measures of occupational pneumoconiosis. Methods: A retrospective survey was conducted during July to December 2020 to explore the survival status of occupational pneumoconiosis patients who had been reported from 1963 to 2020 in Shizuishan City. The Kaplan-Meier method and Life-table method were used for survival analysis, and Cox proportional hazards regression model was used to analyze the influencing factors of survival time. The disability adjusted life years (DALY) was applied to analyze the disease burden of occupational pneumoconiosis and its temporal trend. Results: From 1963 to 2020, a total of 3263 cases of occupational pneumoconiosis were reported in Shizuishan City, of which 1467 died, so that the fatality rate was 44.96%. The median survival time was 26.71 years, average age of death was (70.55±10.92) years old. There were significant differences in the survival rates of occupational pneumoconiosis patients among different types, diagnosis age, exposure time, industry, initial diagnosis stage and whether upgraded (P<0.05) . As the survival time increased, the survival rate of patients decreased gradually. When the survival time was ≥50 years, the cumulative survival rate of patients was 4.20%. Cox regression analysis suggested that the type of pneumoconiosis, industry, diagnosis age, exposure time, initial diagnosis stage and whether upgraded were the influencing factors for the survival time of patients with occupational pneumoconiosis (P<0.05) . The total DALY attributable to occupational pneumoconiosis from 1963 to 2020 in Shizuishan City was 48026.65 person years, of which the years of life lost (YLL) was 15155.39 person years, and the average YLL was 10.33 years/person, and the years lost due to disability (YLD) was 32871.26 person years, and the average YLD was 10.07 years/person. The DALY attributed to coal worker's pneumoconiosis and silicosis were 39408.51 person years and 6565.02 person years, respectively, and they accounted for 82.06% and 13.67% of the total disease burden in Shizuishan City, respectively. The DALY caused by occupational pneumoconiosis in the age group of 40-49 years old and the first diagnosis of stage I occupational pneumoconiosis were higher, which were 20899.71 and 36231.97 person years, respectively. The average YLL and average YLD showed a volatility downtrend over time. Conclusion: The disease burden of occupational pneumoconiosis cannot be ignored in Shizuishan City, and timely targeted measures should be taken for key populations and key industries. It is recommended that life-cycle health management and hierarchical medical should be taken to improve the life quality of patients and prolong their lifes.

ABSTRACT

Objective: To analyze the incidence characteristics of occupational diseases in Guangzhou from 2010 to 2020, provide scientific basis for formulating occupational disease prevention and control policies. Methods: In January 2021, based on the data of occupational diseases in Guangzhou reported in the Information Monitoring System of Occupational Diseases and Occupational Health, descriptive epidemiological method was used to analyze the types and characteristics of occupational diseases in Guangzhou from 2010 to 2020. Results: A total of 1341 cases of 38 kinds of occupational diseases in 9 categories were reported in the past 11 years. The incidence of occupational pneumoconiosis, occupational otolaryngology and oral diseases and occupational chemical poisoning ranked the top three, accounting for 38.1% (511/1341) , 30.5% (409/1341) and 16.2% (217/1341) of the total cases respectively. The cases of pneumoconiosis in welders and silicosis accounted for 47.7% (244/511) and 34.4% (176/511) of the cases of occupational pneumoconiosis respectively. The cases of noise deafness accounted for 99.8% (408/409) of occupational otorhinolaryngology oral diseases. Acute occupational chemical poisoning cases accounted for 26.7% (58/217) of the occupational chemical poisoning cases, in which dichloroethane poisoning cases ranked the first, accounting for 79.3% (46/58) . Chronic occupational chemical poisoning cases accounted for 73.3% (159/217) of the occupational poisoning cases, in which benzene and lead poisoning cases ranked the top two, accounting for 79.2% (126/159) and 17.6% (28/159) respectively. Conclusion: Pneumoconiosis, silicosis, noise deafness, benzene poisoning, lead poisoning, dichloroethane poisoning should be supervised and managed as key occupational diseases in Guangzhou.

ABSTRACT

Objective: To analyze the epidemiological characteristics of pneumoconiosis in Qinghai Province from 2011 to 2020, and to provide a basis for the formulation of prevention and control strategy. Methods: In April 2021 , the cases of pneumoconiosis were monitored by the Occupational Disease and Health Hazard Factors Monitoring Information System in Qinghai Province from 2011 to 2020. The distribution of pneumoconiosis, the composition of diseases and the working years exposed to dust were analyzed. Results: All 1026 cases of pneumoconiosis were newly diagnosed in Qinghai Province from 2011 to 2020, silicosis and coal worker pneumoconiosis were the main diseases (78.36% ,804/1026). Stage Ⅰ pneumoconiosis were 484 (47.17%,484/1026) cases. 359 (34.99%,359/1026) cases, 315 (30.70%,315/1026) cases and 252 (24.56%, 252/1026) cases had been diagnosed respectively in Xining City, Haidong City and Haixi Prefecture; 628 (61.21%,628/1026) cases and 418 (40.74%, 418/1026) cases engaged in mining industry and large-sized enterprise, respectively. The working years exposed to dust in silicosis cases were shorter than that in coal worker pneumoconiosis and other pneumoconiosis (P <0.05). Conclusion: The pneumoconiosis area and industry focus in Qinghai Province is obvious. The supervision and adninistration of small and micro scale employers should be strengthened to protect the health rights and interests of workers, especially for the key area and industry.

ABSTRACT

Objective: To understand the diagnosis of suspected occupational diseases reported in Guangzhou from 2014 to 2019, so as to provide theoretical basis and technical support for the supervision of suspected occupational disease reports. Methods: By cluster sampling, the suspected occupational disease report card, occupational disease report card and pneumoconiosis report card reported by Guangzhou from January 1, 2014 to December 31, 2019 in the occupational disease and occupational health information monitoring system were collected for matching analysis to understand the diagnosis of suspected occupational disease patients. Results: From 2014 to 2019, a total of 1426 suspected occupational cases in 7 categories and 32 species were reported in Guangzhou. The average number of reported cases per year was about 240. The main diseases of suspected occupational diseases were suspected occupational noise deafness (68.44%, 976/1426) , suspected occupational chronic benzene poisoning (16.48%, 235/1426) , suspected occupational other pneumoconiosis (4.84%, 69/1426) , suspected occupational silicosis (3.23%, 46/1426) and suspected occupational welder pneumoconiosis (1.82%, 26/1426) . The diagnostic rate required to enter the occupational disease diagnostic program is 36.61% (522/1426) , and the diagnostic rate is 59.20% (309/522) . In 2019, the diagnosis rate of suspected occupational diseases was the lowest (23.92%, 61/255) , Huadu District was the lowest (8.33%, 9/108) , suspected occupational pneumoconiosis was the lowest (28.03%, 44/157) , the diagnosis rate of suspected occupational diseases reported by the Centers for Disease control and prevention was the lowest (17.43%, 19/109) , and the diagnosis rate of suspected occupational diseases reported by outpatient treatment was the lowest (22.22%, 2/9) . The suspected occupational diseases reported by institutions outside Guangzhou did not enter the occupational disease diagnosis procedure. Suspected occupational skin diseases, suspected occupational diseases caused by physical factors and suspected occupational tumors were diagnosed, and the diagnosis rate of occupational disease prevention and control institutions was the highest (94.87%, 37/39) . Conclusion: The main types of suspected occupational diseases reported during these six years are noise deafness, chronic benzene poisoning and pneumoconiosis. The overall diagnosis rate and diagnosis rate of suspected occupational diseases are not high. It is suggested to improve the network direct reporting system of suspected occupational diseases and strengthen the follow-up management and supervision of suspected occupational diseases.

ABSTRACT

Objective: To analyze the pattern and characteristics of occupational diseases in Weihai City from 2009 to 2020, and to provide scientific basis for the formulation of occupational disease prevention. Methods: In February 2021, retrospective analysis was performed on the cases of occupational diseases diagnosed from 2009 to 2020 in Weihai City. The relevant information and data were collected to analyze the types of occupational diseases, onset age, working age, diagnosis time, industry distribution, economic type and enterprise size distribution. Results: From 2009 to 2020, a total of 453 cases of new occupational diseases were reported in Weihai City. There were 431 males (95.14%) and 22 females (4.86%) . The average onset age was (49.16±8.51) years, and the average working age was (17.89±9.30) years. The incidence of pneumoconiosis and other respiratory diseases (322 cases, 71.08%) , occupational otolaryngology and oral diseases (71 cases, 15.67%) and occupational chemical poisoning (36 cases, 7.95%) were the top 3 cases, of which 313 cases were pneumoconiosis and 69 cases were noise deafness. The cases were mainly concentrated in the 40-59 years age group (357 cases, 78.81%) and the 10-19 years working age group (175 cases, 38.63%) . There were significant differences in the incidence of occupational diseases in different ages and different working ages (χ(2)=97.64, 80.74, P<0.001) . The new cases were mainly in mining industry (134 cases, 29.58%) , shipbuilding or maintenance industry (97 cases, 21.41%) , and private enterprises (350 cases, 77.26%) . Conclusion: Pneumoconiosis and noise deafness are the main emerging occupational diseases in Weihai City. Occupational disease prevention and control in private enterprises such as mining and shipbuilding or maintenance industry should be strengthened.

ABSTRACT

Objective: To detect of gene expression and genotype of the ataxia telangiectasia mutated (ATM) from coal workers' pneumoconiosis (CWP) , It is explored whether CWP is related to ATM gene. Methods: In October 2020, the relevant information of 264 subjects who received physical examination or medical treatment in the Department of occupational diseases of Guiyang public health treatment center from January 2019 to September 2020 was collected. Through the occupational health examination, 67 healthy people with no history of exposure to occupational hazards were selected as the healthy control group; The coal miners with more than 10 years of coal dust exposure history and small shadow in the lung but not up to the diagnostic criteria were the dust exposure control group, a total of 66 people; The patients with the same history of coal dust exposure and confirmed stage I were coal worker's pneumoconiosis stage I group, a total of 131 people. The expression of ATM was detected by QRT PCR. ATM rs189037 and rs1801516 were genotyped by massarray. Results: There was significant difference in the expression of ATM among the groups (P<0.05) ; Compared with the healthy control group, the expression of ATM in the dust exposed control group was significantly increased (P<0.05) . With the occurrence and development of CWP, the GG of rs189037 wild type decreased, the GA of mutant heterozygote and AA of homozygote increased, but the difference was not statistically significant (P>0.05) ; Rs1801516 wild type GG and mutant heterozygote GA had no significant changes (P>0.05) . There were significant differences in age, neutrophils and basophils among rs189037 groups (all P<0.05) . There were no significant differences in blood pressure, eosinophils, lymphocytes, monocytes, smoking and drinking history among rs189037 groups (all P>0.05) . Compared with wild-type GG, the or of mutant heterozygotes and homozygotes increased, but the differences were not statistically significant (P>0.05) . Conclusion: ATM gene may be one of the early activation genes of CWP and rs189037 may be the functional loci which affects gene expression. ATM gene is related to inflammatory response, Neutrophils and basophils have an impact on the development of CWP.

ABSTRACT

Objective: In order to find out the prevalence and death of pneumoconiosis in Qingyuan City, to explore the regularity of pneumoconiosis and lay a foundation for the prevention and management of pneumoconiosis. Methods: In August to December 2019, the basic data of pneumoconiosis from 1949 to 2018 were obtained through the monitoring of death causes of residents, occupational disease management system, Guangdong population information system and other means. The reported cases of pneumoconiosis were followed up, and retrospective investigation was conducted to analyze the basic conditions, the length of service exposed to dust, the time of diagnosis, the type of disease, the stage and the combined status of tuberculosis of pneumoconiosis cases. Results: From 1949 to 2018, a total of 466 cases of new pneumoconiosis were reported in Qingyuan City, including 325 cases of death (69.74%) , 114 cases of survival (24.46%) and 27 cases of loss of follow-up (5.80%) . The cases were mainly concentrated in the age group of 40-89 years (80.04%, 373/466) . There were 411 male cases (88.20%) and 7 female cases (1.50%) . The median length of service exposed to dust was 10.7 (6.0, 16.0) years. The diagnosis time of pneumoconiosis cases was mainly from 1949 to 1986 (68.67%, 320/466) , and the death cases were mainly from 1949 to 1986 (82.77%, 269/325) . Silicosis was the main type of pneumoconiosis (398 cases, 85.41%) . 200 cases (42.92%) were diagnosed as stage I pneumoconiosis, 185 cases (39.69%) were stage II pneumoconiosis, 81 cases (17.38%) were stage III pneumoconiosis at the first diagnosis. 102 cases (21.89%) were pneumoconiosis with tuberculosis. The proportion of death and lost follow-up cases diagnosed as stage I pneumoconiosis for the first time was significantly lower than that of survival cases, and the proportion diagnosed as stage II pneumoconiosis and the complication rate of tuberculosis were significantly higher than those of survival cases (χ(2)=15.48, 11.29, 32.73, P<0.001) . Conclusion: Pneumoconiosis in Qingyuan City is mainly silicosis. The number of new cases has been increasing in the past decade, and the prevention and control situation is still severe. The comprehensive prevention and treatment of silica dust should be included in the focus of supervision of government functional departments.

ABSTRACT

Objective: To analyze the security situation of patients with occupational pneumoconiosis in Gansu Province to lay the foundation for strengthening the security measures for patients with pneumoconiosis. Methods: In August 2020, a follow-up survey was conducted on the current patients with occupational pneumoconiosis diagnosed and surviving in Gansu Province from 1949 to 2019, to obtain the information of industrial injury insurance, employer compensation, medical insurance, subsistence allowance and so on, and analyze their distribution characteristics. The proportion of patients enjoying various security, medical insurance reimbursement and subsistence allowances was tested by chi square. Results: Among the current patients with occupational pneumoconiosis in Gansu Province, 72.0% (5335/7410) enjoyed the benefits of work-related injury insurance, 8.2% (609/7410) enjoyed the compensation paid by the employer, 91.5% (6780/7410) had medical insurance, and 2.8% (204/7410) had no guarantee. Among the patients with occupational pneumoconiosis, 374 enjoyed the minimum living allowance, accounting for 5.05% (374/7410) ; the first diagnosis period with a high proportion of minimum living allowance was phase Ⅲ, accounting for 15.14% (43/284) . Conclusion: The proportion of medical insurance outpatient and inpatient reimbursement of occupational pneumoconiosis patients in Gansu Province is still at a low level. It is suggested that relevant departments should introduce relevant security policies for workers without fixed employers to reduce the economic burden of patients.

ABSTRACT

Pneumoconiosis refers to a spectrum of pulmonary diseases caused by inhalation of mineral dust, usually as the result of certain occupations. The main pathological features include chronic pulmonary inflammation and progressive pulmonary fibrosis, which can eventually lead to death caused by respiratory and/or heart failure. Pneumoconiosis is widespread globally, seriously threatening global public health. Its high incidence and mortality lie in improper occupational protection, and in the lack of early diagnostic methods and effective treatments. This article reviews the epidemiology, safeguard procedures, diagnosis, and treatment of pneumoconiosis, and summarizes recent research advances and future research prospects.

ABSTRACT

This study identifies the number of pneumoconiosis patients after eliminating deceased patients between 2003 and 2008 as of January 1st and estimates it for the next five years. From 2003 to 2008, the pneumoconiosis patients were 16,929, 17,224, 17,366, 17,566, 17,542, and 17,546, respectively. The number of pneumoconiosis patients will have increased by 1,014 from 2008 to 18,560 in 2013 after applying the average change rates taken from 2003 to 2007. It takes 15-20 yr to develop coal workers' pneumoconiosis (the main cause in Korea) and patients will continue to be diagnosed with pneumoconiosis for some years to come since it has only been 20 yr since the decline of the coal mining industry in Korea. In addition, pneumoconiosis patients are increasing in industries in which the risk of pneumoconiosis was relatively low shows the necessity to improve dust-exposed workplace environments.

ABSTRACT

OBJETIVO: Desenvolver e consolidar uma ampla base de dados acerca da ocorrência das pneumoconioses numa região industrializada do Brasil, com especial referência às atividades mais freqüentemente relacionadas a essas doenças. MÉTODOS: Numa avaliação retrospectiva observacional, coletaram-se dados referentes à casuística ambulatorial das pneumoconioses no Hospital das Clínicas da Universidade Estadual de Campinas, entre o período de 1978 e 2003. Incluíram-se os indivíduos com diagnóstico de pneumoconiose, com base no histórico ocupacional e no radiograma do tórax, segundo recomendações da Organização Internacional do Trabalho, de 1980 e 2000, com anormalidades compatíveis com comprometimento intersticial do parênquima pulmonar. RESULTADOS: Foram identificados 1.147 casos de pneumoconiose (1.075 homens e 72 mulheres), sendo 1.061 casos (92,5 por cento) de silicose, 51 (4,45 por cento) de pneumoconiose por poeira mista, 15 (1,31 por cento) de asbestose, 13 (1,13 por cento) de pneumoconiose por rocha fosfática e 7 (0,61 por cento) de outras pneumoconioses (por carvão, grafite e metais duros). As alterações radiológicas com profusão 1/0, 1/1 e 1/2 e as pequenas opacidades regulares p, q e r foram as mais freqüentes, tendo sido identificados 192 casos (16,74 por cento) com grandes opacidades. Observou-se redução pronunciada da ocorrência dos casos a partir da década de 1990; adicionalmente, o tempo de exposição foi caracteristicamente mais breve do que o observado em série norte-americana. CONCLUSÕES: Os dados do presente estudo estabelecem uma ampla base de dados para a investigação da ocorrência de pneumoconioses numa região industrializada brasileira, tornando factível a realização de estudos de seguimento e a elaboração de políticas de saúde relacionadas aos agravos respiratórios ocupacionais.


OBJECTIVE: To develop and consolidate a comprehensive database on the occurrence of pneumoconioses in an industrialized region of Brazil, with a special focus on the activities most frequently related to these diseases. METHODS: A retrospective, observational study was conducted in order to gather data on cases of pneumoconioses treated at the outpatient clinic of the State University at Campinas Hospital das Clínicas between 1978 and 2003. Individuals diagnosed with pneumoconiosis, based on their occupational history and on chest X-ray findings of abnormalities consistent with interstitial lung disease involving the parenchyma, in accordance with the 1980 and 2000 recommendations of the International Labour Organization, were included in the study. RESULTS: A total of 1147 cases of pneumoconiosis were identified (1075 in males and 72 in females): 1061 cases of silicosis (92.5 percent); 51 cases of mixed-dust pneumoconiosis (4.45 percent); 15 cases of asbestosis (1.31 percent); 13 cases of phosphate rock-related pneumoconiosis (1.13 percent); and 7 cases of other types of pneumoconiosis (0.6 percent), including those related to exposure to coal, graphite and hard metals. The most common chest X-ray findings were 1/0, 1/1 or 1/2 profusion and small regular opacities (p, q or r), although 192 patients (16.74 percent) presented large opacities. There has been a substantial decline in the occurrence of the disease since the 1990s, and the duration of exposure was typically shorter than that observed in a study conducted in the United States. CONCLUSIONS: Our findings have been compiled into a comprehensive database for the investigation of pneumoconiosis in an industrialized area of Brazil.

ABSTRACT

No Brasil encontram-se em crescimento os índices de prevalência das doenças crônicas causadas pela exposição dos trabalhadores à poeiras minerais, sendo a silicose a pneumoconiose de maior prevalência, realizou-se estudo com objetivo de estimar o risco de silicose e propor ações preventivas.Métodos: Realizou-se estudo transversal em 27 marmorarias, no município de São Paulo que executavam o beneficiamento final de rochas ornamentais, que inclui: a) avaliação da exposição à poeiras e à sílica cristalina respirável por meio de coleta de amostras de ar, análise química por gravimetria e difração de Raios X e acumulação das exposições estimadas por função conforme história ocupacional; b) aplicação de questionário de sintomas respiratórios e avaliação médica, espirometria e radiografia do tórax; c) correlação dos resultados de exposição acumulada, com achados clínicos e radiológicos por meio de análises estatísticas; d) levantamento de informações sobre os processos de trabalho e alternativas de controle. Resultados: Os acabadores possuíam a maior exposição, concentração de 0,36 mg m3 (IC 95 por cento 0,32 a 0,47) para granitos e de 0,19 mg m3 (IC 95 por cento 0,16 a 0,23) para a mistura de matérias primas. Para estimativa de exposição acumulada à sílica cristalina respirável de 0,56 mg m3 anos existiu risco de OD = 1,2 (IC 95 por cento 1,02 a 1,40) de o trabalhador exposto apresentar classificação radiológica alterada, profusão maior ou igual 1, em relação a um trabalhador não exposto, com tempo médio de exposição de 19,9 ( mais ou menos 13,0) anos.A população possuía baixo nível de escolaridade e de renda familiar com média de idade 35,8 ( mais ou menos 11,6) anos.

ABSTRACT

En el presente trabajo se describen 1469 casos diagnosticados como enfermedad del trabajo por la Unidad de Investigación, Docencia y Apoyo Clínico en Salud en el Trabajo, del Hospital General Regional No. 46 del Instituto Mexicano del Seguro Social en Guadalajara, Jalisco, en el lapso comprendido de enero de 1985 a octubre de 1993. Los diagnósticos más frecuentes fueron: trauma acústico crónico, dermatitis por contacto, neumoconiosis, bronquitis crónica y saturnismo, todos coinciden con lo reportado a nivel nacional. De las enfermedades de trabajo al momento del estudio 55 por ciento ameritaron evaluación por presentar secuelas irreversibles. Es prioritaria la implementación de programas de vigilancia epidemiológica en las empresas para prevenir los riesgos y disminuir las enfermedades de trabajo

ABSTRACT

A pneumoconiose de mineiros de carväo (PMC) varia em prevalência e incidência em países de carväo. A incidência, progressäo radiológica e probabilidade de PMC foram calculadas em coorte de 2080 mineiros de subsolo, que faziam parte de amostra original de 956 mineiros que foram avaliados em 1984 e 1989. A prevalência pontual de PMC foi determinada com dados da amostra original. As radiografias foram interpretadas por três leitores independentes, segundo critérios da classificaçäo da OIT de 1980. A mediana das leituras foi utilizada para a expressäo dos resultados. A prevalência pontual de PMC foi de 5,6 por cento na amostra original de 1984. A média de exposiçäo de mineiros com PMC foi de 8,4 anos. A soma de anos de subsolo (SANO) e a soma de anos de subsolo ajustada (SANOAJ) associaram-se significativamente à PMC, mas a SANOAJ apresentou melhor ajuste (a SANOAJ é obtida através da multiplicaçäo de anos de subsolo por um fator de 1,2 ou 4 para cada atividade específica). A incidência anual de PMC no período foi de 11,4/1.000 mineiros em risco. A probabilidade de PMC após o índice 60 de SANOAJ foi ao redor de 20 por cento. Nos últimos quatro anos, foram diagnosticados 248 casos novos de PMC, correspondendo a 8 por cento do total de casos na regiäo. Este declínio é devido à contraçäo da indústria carbonífera na década de 80. Concluímos que, embora a prevalência de PMC seja similar à prevalência observada em outros países, a alta incidência, o pequeno período de latência e os gráficos probabilísticos apontam para uma situaçäo grave na mineraçäo de carväo brasileiro

ABSTRACT

A silicose em cavadores de poços tem-se apresentado como grave problema de saúde ocupacional, despertando,desde sua descoberta, em 1984, no Piauí, e em 1986, no Ceará, o interesse de médicos pneumologistas e de outras disciplinas näo médicas com relaçäo ao seu conhecimento e controle. No presente estudo, säo abordados: a história natural da doença, apresentando peculiaridades próprias, pouco encontradas em outras atividades, como o processo primitivo de escavaçäo de poços, os riscos aos quais os cavadores estäo sujeitos, as características anatomopatológicas e a classificaçäo do tipo acelerada quanto à forma de apresentaçäo; os dados epidemiológicos que revelam prevalência de silicose e provável silicose em 180 (26,4 por cento) dos 687 cavadores examinados, prevalência de silicotuberculose em 13 (7,2 por cento) dos 180 diagnosticados e elevada freqência de óbitos, 34 (39,5 por cento) de 86 silicóticos diagnosticados entre 1986 e 1989. As medidas de controle que poderäo ser capazes de interromper o ciclo natural da doença säo discutidas

ABSTRACT

Relata-se a experiência na implantaçäo de um programa de saúde ocupacional, destacando-se a sistemática e a metodologia desenvolvidas no programa de proteçäo respiratória, em três fundiçöes de empresa multinacional automobilística. Através de um grupo de trabalho composto por médicos do trabalho, engenheiros de segurança e um higienista industrial, foram levantadas as condiçöes e ambientes de trabalho, estabelecendo-se um processo de vigilância médica, o qual permitiu açöes preventivas e corretivas, tanto no que se refere a local de trabalho como no tocante à saúde do trabalhador. Relatam-se os resultados das avaliaçöes médicas e ambientais, além de fato relevante a respeito do uso de máscaras descartáveis, utilizadas como proteçäo respiratória. As conclusöes do programa confirmaram a necessidade de se estabelecer controles sobre o trabalhador e seu ambiente de trabalho em fundiçöes e a validade da realizaçäo de censos espirométricos ao longo do tempo
