Crystalline silica exposure, radiological silicosis, and lung cancer mortality in diatomaceous earth industry workers. (1/330)
BACKGROUND: The role of silicosis as either a necessary or incidental condition in silica associated lung cancer remains unresolved. To address this issue a cohort analysis of dose-response relations for crystalline silica and lung cancer mortality was conducted among diatomaceous earth workers classified according to the presence or absence of radiological silicosis. METHODS: Radiological silicosis was determined by median 1980 International Labour Organisation system readings of a panel of three "B" readers for 1809 of 2342 white male workers in a diatomaceous earth facility in California. Standardised mortality ratios (SMR) for lung cancer, based on United States rates for 1942-94, were calculated separately for workers with and without radiological silicosis according to cumulative exposures to respirable crystalline silica (milligrams per cubic meter x years; mg/m3-years) lagged 15 years. RESULTS: Eighty one cases of silicosis were identified, including 77 with small opacities of > or = 1/0 and four with large opacities. A slightly larger excess of lung cancer was found among the subjects with silicosis (SMR 1.57, 95% confidence interval (CI) 0.43 to 4.03) than in workers without silicosis (SMR 1.19, 95% CI 0.87 to 1.57). An association between silica exposure and lung cancer risk was detected among those without silicosis; a statistically significant (p = 0.02) increasing trend of lung cancer risk was seen with cumulative exposure, with SMR reaching 2.40 (95% CI 1.24 to 4.20) at the highest exposure level (> or = 5.0 mg/m3-years). A similar statistically significant (p = 0.02) dose-response gradient was observed among non-silicotic subjects when follow up was truncated at 15 years after the final negative radiograph (SMR 2.96, 95% CI 1.19 to 6.08 at > or = 5.0 mg/m3-years), indicating that the association among non-silicotic subjects was unlikely to be accounted for by undetected radiological silicosis. CONCLUSIONS: The dose-response relation observed between cumulative exposure to respirable crystalline silica and lung cancer mortality among workers without radiological silicosis suggests that silicosis is not a necessary co-condition for silica related lung carcinogenesis. However, the relatively small number of silicosis cases in the cohort and the absence of radiographic data after employment limit interpretations. (+info)End stage renal disease among ceramic workers exposed to silica. (2/330)
OBJECTIVES: To evaluate whether ceramic workers exposed to silica experience an excess of end stage renal disease. METHODS: On the basis of a health surveillance programme, a cohort of 2980 male ceramic workers has been enrolled during the period 1974-91 in Civitacastellana, Lazio, Italy. For each worker, employment history, smoking data, and x ray film readings were available. The vital status was ascertained for all cohort members. All 2820 people still alive and resident in the Lazio region as in June 1994 were searched for a match in the regional end stage renal diseases registry, which records (since June, 1994) all patients undergoing dialysis treatment in public and private facilities of the region. Expected numbers of prevalent cases from the cohort were computed by applying the rate of patients on dialysis treatment by the age distribution of the cohort. RESULTS: A total of six cases was detected when 1.87 were expected (observed/expected (O/E) = 3.21; 95% confidence interval (95% CI) 1.17 to 6.98). The excess risk was present among non-smokers (O = 2; O/E = 4.34) and smokers (O = 4; O/E = 2.83), as well as among workers without silicosis (O = 4; O/E = 2.78) and workers with silicosis (O = 2; O/E = 4.54). The risk was higher among subjects with < 20 years since first employment (O = 4; O/E = 4.65) than among those employed > 20 years. CONCLUSION: These results provide further evidence that exposure to silica dust among ceramic workers is associated with nephrotoxic effects. (+info)Left recurrent laryngeal nerve palsy associated with silicosis. (3/330)
Left recurrent laryngeal nerve palsy usually results from invasion or compression of the nerve caused by diseases localized within the aortopulmonary window. This study reports the case of a 76-yr-old male with vocal cord paralysis due to lymph node involvement by silicosis. This rare entity was identified by video-mediastinoscopy, which revealed a granulomatous and fibrosed recurrent lymph node encasing the nerve. The nerve was dissected and released from scar tissues. Progressive clinical improvement was observed followed by total and durable recovery of the voice after 15 weeks follow-up. (+info)Serum levels of soluble Fas ligand in patients with silicosis. (4/330)
Certain patients with silicosis have been reported to exhibit immunological abnormalities such as the appearance of antinuclear antibodies and the occurrence of autoimmune diseases. Fas ligand (FasL) is a type II membrane protein which induces apoptosis by binding to its membrane receptor, Fas. FasL is converted to a soluble form by a metalloproteinase-like enzyme. We have already found serum soluble Fas (sFas) levels in silicosis patients as well as in patients with systemic lupus erythematosus (SLE) to be significantly higher than those in healthy volunteers. To examine further the role of the Fas/FasL system in silica-induced immunological abnormalities, we investigated serum soluble FasL (sFasL) levels in silicosis patients with no clinical symptoms of autoimmune diseases, using ELISA for sFasL. Although the serum sFasL levels in patients with SLE were significantly higher than those in healthy volunteers and showed a slight positive correlation with serum sFas levels, those in silicosis patients exhibited no significant difference from those in healthy volunteers, and there was no correlation with serum sFas levels. However, sFasL levels were elevated in silicosis patients with slight dyspnoea or normal PCO2 among various clinical parameters of silicosis. It may be speculated that the immunological disturbances presented by the abnormalities of apoptosis-related molecules in silicosis patients do not occur with a similar degree of respiratory involvement. Further studies are required to clarify which kinds of factors are involved in silicosis patients who exhibit immunological abnormalities. (+info)Over-expression of the decoy receptor 3 (DcR3) gene in peripheral blood mononuclear cells (PBMC) derived from silicosis patients. (5/330)
Dysregulation of apoptosis, particularly in the Fas/Fas ligand (FasL) pathway, is considered to be involved in the pathogenesis of autoimmune diseases such as systemic lupus erythematosus (SLE). Recently, a soluble decoy receptor, termed decoy receptor 3 (DcR3), that binds FasL and inhibits FasL-induced apoptosis, has been identified. Silicosis is clinically characterized not only by respiratory disorders but by immunological abnormalities. We have found that serum soluble Fas (sFas) levels are elevated in silicosis patients and that sFas message is dominantly expressed in PBMC derived from these patients. This study examined DcR3 gene expression in PBMC derived from patients with silicosis, SLE, or progressive systemic sclerosis (PSS), and compared it with that in healthy volunteers (HV). The relative expression level of the DcR3 gene was examined in PBMC derived from 37 patients with silicosis without clinical symptoms of autoimmune disease, nine patients with SLE, 12 patients with PSS, and 28 HV using the semiquantitative multiplex-reverse transcriptase-polymerase chain reaction (MP-RT-PCR). The correlation between the relative expression level of the DcR3 gene and multiple clinical parameters for respiratory disorders and immunological abnormalities in individuals with silicosis was analysed. The DcR3 gene was significantly over-expressed in cases of silicosis or SLE when compared with HV. In addition, the DcR3 relative expression level was positively correlated with the serum sFas level in silicosis patients. It is unclear, however, whether over-expression of the DcR3 gene in silicosis is caused by chronic silica exposure, merely accompanies the alteration in Fas-related molecules, or precedes the clinical onset of autoimmune abnormalities. It will be necessary to study these patients further, establish an in vitro model of human T cells exposed recurrently to silica compounds, and resolve whether the increase in DcR3 mRNA expression is a cause or consequence of disease. (+info)Occupational lung cancer risk for men in Germany: results from a pooled case-control study. (6/330)
Occupational exposures such as crystalline silica, diesel engine exhaust, polycyclic aromatic hydrocarbons, and man-made mineral fibers are strongly suspected to increase lung cancer risk. Two case-control studies in Germany conducted between 1988 and 1996 were pooled for a joint analysis. A total of 3,498 male cases and 3,541 male population controls, frequency matched for age and region, were included in the study. The lifelong history of all jobs and industries was coded and occupational exposures were evaluated by expert rating. Odds ratios, crude and adjusted for smoking and asbestos exposure, were calculated by conditional logistic regression. Job-related evaluation showed a statistically significant increased odds ratio adjusted for smoking among farmers; forestry workers, fishermen, and livestock workers; miners and quarrymen; chemical processors; cabinet makers and related wood workers; metal producers and processors; bricklayers and carpenters; road construction workers, pipelayers and well diggers; plasterers, insulators, and upholsterers; painters and lacquerers; stationary engine and heavy equipment operators; transport workers and freight handlers; and service workers. With regard to specific occupational exposures, elevated odds ratios (OR) (95% confidence intervals (CI)) for lung cancer risk adjusted for smoking and asbestos exposure were observed for man-made mineral fibers (OR = 1.48, 95% CI 1.17, 1.88); crystalline silica (OR = 1.41, 95% CI 1.22, 1.62); diesel engine exhaust (OR = 1.43, 95% CI 1.23, 1.67); and polycyclic aromatic hydrocarbons (OR = 1.53, 95% CI 1.14, 2.04). The risk of asbestos exposure, adjusted for smoking was also increased (OR = 1.41, 95% CI 1.24, 1.60). (+info)Risk factors for pulmonary disease due to culture-positive M. tuberculosis or nontuberculous mycobacteria in South African gold miners. (7/330)
The aim of this study was to determine risk factors for disease due to nontuberculous mycobacteria (NTM) compared to those due to Mycobacterium tuberculosis in South African gold miners with pulmonary mycobacterial disease. A case/control study comparing tuberculosis and NTM cases amongst all patients with a positive sputum mycobacterial culture in 1995 was carried out. The 51 cases of disease due to NTM and 425 tuberculosis cases were similar with regard to age, education, home region, smoking habits and percentage of CD4 cells. After adjustment for confounders, those with NTM were more likely to have had previous tuberculosis treatment (odds ratio (OR) 3.61; 95% confidence interval (CI) 1.9-6.9), have worked longer underground (p-value for trend=0.05) or have evidence of silicosis (OR 12.6; 95% CI 2.2-71) and were less likely to drink regularly (OR 0.12; 95% CI 0.02-0.93) than patients with tuberculosis. In patients with disease due to NTM, 35.3% were human immunodeficiency virus-positive compared with 48.8% of tuberculosis patients (p=0.2) and an estimated 21% overall in the mines at the time of the study. Previous tuberculosis treatment, silicosis and duration of underground work are even more strongly associated with disease due to nontuberculous mycobacteria than with tuberculosis. Attempts to reduce the incidence of all pulmonary mycobacterial disease in this community should address recognized risk factors and ensure that those with tuberculosis are diagnosed, treated and cured. (+info)Low serum alpha-1-antitrypsin level as a contributory factor of combined emphysema in silicosis. (8/330)
In order to evaluate low serum alpha-1-antitrypsin level as a contributory factor of combined emphysema in silicotic patients, serum alpha-1-antitrypsin analysis was carried out in 80 patients with silicosis. Low serum alpha-1-antitrypsin level was found in 5 patients. Large opacities were observed roentgenologically in only 1 out of these 5 cases in contrast to 31 of the other 75 cases. Also the suggestive findings for the emphysema were showed in 4 of these 5 cases while such findings were found on their chest X-ray films in only 43 of the other 75 cases. FEV 1.0% below 50 were calculated in 3 of the 5 cases, on the contrary in 22 of the 75 cases. RV above 50% predicted value was showed by all the 5 low antitrypsin patients, in contrast to only 25 of other 74 cases. The silicotic patients with low serum alpha-1-antitrypsin concentration are most likely to have an association with a high incidence of complicated emphysema. (+info)Silicosis is a lung disease caused by the inhalation of crystalline silica dust. It is characterized by the formation of scar tissue in the lungs, which can lead to shortness of breath, coughing, and chest pain. The disease is most commonly associated with the mining and processing of minerals such as quartz, sandstone, and granite, as well as with the manufacture of glass and ceramics. Silicosis can be acute, subacute, or chronic, depending on the duration and intensity of exposure to silica dust. It is a preventable disease, and steps can be taken to reduce exposure to silica dust in the workplace.
Silicon dioxide, also known as silica, is a naturally occurring compound that is commonly used in the medical field. It is a hard, white, crystalline solid that is composed of silicon and oxygen atoms. In the medical field, silicon dioxide is used in a variety of applications, including as a pharmaceutical excipient, a food additive, and a wound dressing material. It is often used as a carrier for other active ingredients in medications, as it can help to improve the stability and bioavailability of the drug. Silicon dioxide is also used in the production of various medical devices, such as implants and prosthetics, as well as in the manufacturing of dental materials and orthopedic implants. In addition to its use in medical applications, silicon dioxide is also used in a variety of other industries, including electronics, construction, and cosmetics.
Silicotuberculosis is a type of lung disease caused by inhaling silica dust, which is a common mineral found in sand, rock, and some types of glass. The disease is also known as silicosis and is characterized by the formation of scar tissue in the lungs, which can lead to shortness of breath, coughing, and chest pain. Silicosis can be acute or chronic, depending on the duration and intensity of exposure to silica dust. Acute silicosis typically develops within a few months to a few years of exposure and is characterized by the formation of small nodules in the lungs. Chronic silicosis, on the other hand, develops over a longer period of time and is characterized by the formation of larger nodules that can merge together to form a mass in the lungs. Silicotuberculosis is a serious and potentially life-threatening condition, and it is important for workers who are exposed to silica dust to take precautions to protect themselves, such as wearing protective gear and using ventilation systems to reduce exposure. Treatment for silicosis may include medications to manage symptoms and oxygen therapy to improve breathing. In severe cases, surgery may be necessary to remove damaged lung tissue.
In the medical field, "quartz" typically refers to a type of mineral that is commonly used in the production of medical devices and instruments. Quartz is a hard, crystalline mineral that is composed of silicon dioxide (SiO2) and is known for its high refractive index, which makes it useful for producing lenses and other optical components. Quartz is often used in the production of medical devices such as microscopes, spectrometers, and lasers. It is also used in the manufacture of surgical instruments, such as scalpels and forceps, due to its durability and resistance to corrosion. In addition to its use in medical devices, quartz is also used in the production of certain types of medical implants, such as dental fillings and orthopedic implants. However, it is important to note that the use of quartz in medical implants is relatively uncommon, and other materials such as titanium and stainless steel are more commonly used for this purpose.
In the medical field, dust refers to a mixture of small particles that are suspended in the air. These particles can come from a variety of sources, including soil, pollen, pet dander, and human skin cells. Dust can be inhaled and can cause a range of health problems, including respiratory issues such as asthma, bronchitis, and pneumonia. It can also cause irritation of the eyes, nose, and throat, and can exacerbate existing conditions such as allergies and eczema. In some cases, exposure to certain types of dust can be hazardous, such as asbestos or silica dust, which can cause serious health problems if inhaled in large quantities.
In the medical field, "gold" typically refers to the use of gold compounds in the treatment of certain medical conditions. Gold has been used in medicine for centuries, and it is still used today in the treatment of certain autoimmune diseases, such as rheumatoid arthritis and lupus. Gold therapy involves the administration of gold compounds, usually in the form of a pill or injection, to help reduce inflammation and pain. The exact mechanism of action of gold therapy is not fully understood, but it is thought to involve the modulation of the immune system and the production of anti-inflammatory molecules. Gold therapy is generally considered safe and effective, although it can cause side effects such as nausea, vomiting, and skin rashes. It is important to note that gold therapy is not suitable for everyone, and it should only be used under the guidance of a qualified healthcare professional.
I'm sorry, but I cannot find any definition of "Coal Mining" in the medical field. Coal mining is a term used in the field of geology and mining to describe the process of extracting coal from the ground. It is not typically associated with medicine or healthcare. If you have any other questions or if there is anything else I can help you with, please let me know.
Occupational diseases are illnesses or injuries that are caused by exposure to hazards or conditions in the workplace. These hazards or conditions can include chemicals, dusts, fumes, radiation, noise, vibration, and physical demands such as repetitive motions or awkward postures. Occupational diseases can affect various systems in the body, including the respiratory system, skin, eyes, ears, cardiovascular system, and nervous system. Examples of occupational diseases include asbestosis, silicosis, coal workers' pneumoconiosis, carpal tunnel syndrome, and hearing loss. Occupational diseases are preventable through proper safety measures and regulations in the workplace. Employers are responsible for providing a safe and healthy work environment for their employees, and workers have the right to report hazards and seek medical attention if they experience any symptoms related to their work.
Pneumoconiosis is a group of lung diseases caused by the inhalation of dust particles that are small enough to be breathed deep into the lungs. These dust particles can be made up of a variety of materials, including coal, silica, asbestos, and other minerals. Over time, the dust particles can accumulate in the lungs and cause inflammation, scarring, and other damage to the lung tissue. This can lead to a range of symptoms, including shortness of breath, coughing, and chest pain. Pneumoconiosis can be a serious and potentially life-threatening condition, and it is important for people who work in industries that involve exposure to dust particles to take steps to protect themselves from the risk of developing this disease.
In the medical field, uranium is primarily used as a radioactive isotope for diagnostic and therapeutic purposes. One of the most common uses of uranium in medicine is in nuclear medicine, where it is used to create radiopharmaceuticals that can be used to diagnose and treat various diseases. For example, uranium-235 is used to produce technetium-99m, which is a widely used radiopharmaceutical for imaging the heart, brain, bones, and other organs. Uranium-238 is also used in radiation therapy to treat cancer. In this treatment, small amounts of uranium-238 are administered to the patient, and the radioactive decay of the uranium-238 produces alpha particles that can damage cancer cells and kill them. However, it is important to note that uranium is also a highly toxic heavy metal and can cause serious health problems if not handled properly. Therefore, its use in medicine is carefully regulated and monitored to ensure the safety of patients and medical personnel.
In the medical field, "tin" typically refers to a type of metal that is used in the production of certain medical devices and implants. Tin is a soft, silvery-white metal that is often alloyed with other metals, such as copper or zinc, to improve its strength and durability. One common use of tin in medicine is in the production of orthopedic implants, such as hip and knee replacements. Tin can be alloyed with other metals to create a strong, corrosion-resistant material that is suitable for use in the body. Tin is also used in the production of certain types of medical equipment, such as X-ray machines and MRI machines. In these applications, tin is used to shield the equipment from external radiation and to protect patients from unnecessary exposure to radiation. Overall, tin is an important material in the medical field due to its strength, durability, and ability to be alloyed with other metals to create a wide range of medical devices and implants.
