October 31st, 2008. Crocidolite and Mesothelioma
The authors performed a detailed analysis of cases in which crocidolite was identified in the absence of amosite. Most of such cases were identified in recent years, a finding of concern since crocidolite is considered the most potent fiber type with respect to the pathogenesis of mesothelioma.
October 23rd, 2008. The mortality of women exposed environmentally and domestically to blue asbestos at Wittenoom, Western Australia
Conclusion: Women who were former residents of Wittenoom, exposed to asbestos in their environment or in their home, have excess cancer mortality, including mesothelioma, compared with the Western Australian female population.
October 22nd, 2008. A case of non-tuberculous mycobacteriosis with pleurisy with a past history of dense exposure to environmental asbestos
A final diagnosis of NTM was confirmed via open biopsy of the lung. Our case suggests that in addition to tuberculosis, NTM should be taken into consideration as a complication of silicosis.
September 24th, 2008. The relationship between malignant mesothelioma and an asbestos cement plant environmental risk: a spatial case–control study in the city of Bari (Italy)
Conclusion: Evidence of an association between mesothelioma risk and EAE is highlighted. The role played by the RMR in increasing the public health local authorities awareness is stressed. Keywords Asbestos-cement plant - Environmental-neighborhood exposure - Mesothelioma register - Spatial case–control study - Public health - Italy
September 23rd, 2008. Predicted mortality from malignant mesothelioma among women exposed to blue asbestos at Wittenoom, Western Australia
Conclusion: The high toll from mesothelioma in this cohort of women and girls will continue well into the future.
September 13th, 2008. Pathogenesis of malignant pleural mesothelioma and the role of environmental and genetic factors
Conclusion: Many risk factors for MPM development have been recognized including environmental exposures, genetic susceptibility, viral contamination, and radiation. In this review, we discuss the current molecular and genetic contributors to MPM pathogenesis and the risk factors associated with these carcinogenic processes.
September 9th, 2008. Clinical consequences of asbestos-related diffuse pleural thickening: A review
It causes a restrictive defect on lung function and may rarely result in respiratory failure and death. Treatment is primarily supportive.

August 23rd, 2008. Asbestos clinics and asbestos health examinations–findings from a questionnaire survey of implementing organizations
The organizations we surveyed have important roles to play. Although resources are limited, effective diagnosis and treatment are essential, and a system assisting organizations to make accurate and efficient identification of asbestos exposure hazards is imperative.
August 8th, 2008. A Meta-Analysis of Asbestos-Related Cancer Risk That Addresses Fiber Size and Mineral Type
(2007) recently analyzed by TEM archived air samples from the South Carolina plant to determine a detailed distribution of fiber lengths up to lengths of 40 μ m and greater. If similar data become available for Quebec, perhaps these two size distributions can be used to eliminate the discrepancy between these two studies.
August 8th, 2008. Sensitivity analysis of the relationship between disease occurrence and distance from a putative source of pollution
However, as the models appeared to be sensitive to modeling choices, we suggest that any analysis of disease risk around a putative source should be integrated with a careful sensitivity analysis and possibly with prior knowledge. The choice of prior distribution is extremely important and should be based on epidemiological considerations.

August 1st, 2008. Update of Potency Factors for Asbestos-Related Lung Cancer and Mesothelioma
, chrysotile or crocidolite) of an asbestos structure. An analysis is conducted to determine how well different KL and KM definitions are able to reconcile the discrepancies observed herein among values obtained from different environments.
July 25th, 2008. Environmental exposure to Libby asbestos and mesotheliomas
Results: These exposures are considered to be of a low degree of magnitude, but are similar to those in Western Australia's crocidolite mine at Wittenoom Gorge. An epidemic of mesothelioma can likely be expected from this type of asbestos contamination over the next 20 plus years.
June 24th, 2008. Separation and Characterization of Respirable Amphibole Fibers from Libby, Montana
Such harvesting of respirable fractions will allow toxicological studies to be conducted within a controlled laboratory setting, utilizing fiber sizes that may more accurately simulate historical exposure of Libby residents' lungs. Importantly, this work describes a method that allows the use of material enriched in more uniform respirable material than raw Libby 6-mix, making comparisons with other known fiber preparations more valid on a mass basis.
June 24th, 2008. Select mortality and cancer incidence among residents in various U.S. communities that received asbestos-contaminated vermiculite ore from Libby, Montana
No statistically significant excesses of asbestosis mortality similar to those in Libby were noted; however, 11 sites (plus a state with 6 pooled sites that were counted as 1 site) had excess rates of mesothelioma and cancer of the peritoneum, retroperitoneum, and pleura. Further investigation should be conducted at these sites with excess rates of mesothelioma and cancer of the peritoneum, retroperitoneum, and pleura by participating state health departments to determine whether exposure to Libby vermiculite might have been a contributing factor.
June 17th, 2008. Mapping the Risk of Mesothelioma due to Neighborhood Asbestos Exposure
Conclusions: Neighborhood exposure to asbestos can pose a serious risk to residents across a wide area.
June 6th, 2008. Excess of Mesotheliomas after Exposure to Chrysotile in Balangero, Italy
Conclusions: The cluster of 14 mesothelioma cases among workers who were active in the mine and 13 among other people exposed to Balangero chrysotile adds further evidence to the carcinogenicity of tremolite-free chrysotile.
June 4th, 2008. Mesothelioma due to environmental exposure to erionite in Turkey
It has also been confirmed that a genetic predisposition to erionite carcinogenesis is the cause of the mesothelioma epidemic in Cappadocia. Summary: The data obtained recently on the epidemiology, etiology, and pathogenesis of the mesothelioma due to erionite exposure in Turkey are described.
May 30th, 2008. Two cases of asbestosis and one case of rounded atelectasis due to non-occupational asbestos exposure
The three cases indicate that non-neoplastic, long-latency asbestos-related diseases which are usually observed as a consequence of occupational exposures, may rarely develop in subjects living in contaminated geographical sites and buildings. These unusual environmental diseases raise the diagnostic problem of differentiating them from other, more common respiratory illnesses, and impose the duties of patient notification, assessment and follow-up, to assess the possibility of progression of disease and increased neoplastic risk.
May 29th, 2008. Erionite-induced pleural plaques : Exposition to urban pollution in a female Turkish migrant in Germany
Short-term clinical and radiologic control of the patient will be necessary because of the risk of MPM. For epidemiologic considerations discussed referring to current literature, a growing incidence of this type of disease in migrants from high-risk areas must be reckoned with in Germany, even without exposition to asbestos.
