Asbestosis in the Netherlands is a rare work-related form of pulmonary fibrosis caused by long-term, intensive exposure to asbestos. It can have a great impact on patients' quality of life and life expectancy even 20-30 years after initial exposure. The Dutch Institute of Asbestos Victims (IAS) mediates between the victims and their employers or former employers about payment of compensation. Liability procedures against a previous employer are long and stressful. Since 1 April 2014 it has, therefore, been possible to receive financial aid from the state...

The Tyler asbestos plant produced pipe insulation from 1954 to 1972 and exclusively used amosite asbestos. There were 1130 former workers of this plant during the period of operation. A death certificate mortality analysis was published regarding this plant in 1998 for the period through 1993. This study represents an update of the mortality analysis with additional certificates collected for deaths occurring through 2011.Searches of the National Death Index database were conducted in 2004 and again in 2013...

REVIEW
Mutlay Sayan, Brooke T Mossman
The concept of the inflammasome, a macromolecular complex sensing cell stress or danger signals and initiating inflammation, was first introduced approximately a decade ago. Priming and activation of these intracellular protein platforms trigger the maturation of pro-inflammatory chemokines and cytokines, most notably, interleukin-1β (IL-1β) and IL-18, to promulgate innate immune defenses. Although classically studied in models of gout, Type II diabetes, Alzheimer's disease, and multiple sclerosis, the importance and mechanisms of action of inflammasome priming and activation have recently been elucidated in cells of the respiratory tract where they modulate the responses to a number of inhaled pathogenic particles and fibres...

Asbestosis is the most important change noted in the lung parenchyma after environmental and occupational exposure to asbestos fibers. It is characterized by diffuse interstitial pulmonary fibrosis. In Korea, the incidence of asbestosis will continue to increase for many years to come and the government enacted the Asbestos Damage Relief Law in 2011 to provide compensation to those suffering from asbestos-related diseases. Radiologic evaluation is necessary for diagnosis of asbestosis, and radiologists play a key role in this process...

OBJECTIVES: Asbestos bodies (AB) in bronchoalveolar lavage (BAL) can be detected by light microscopy and their concentration is indicative of past cumulative asbestos exposure. We assessed clinical and exposure characteristics, as well as possible time trends, among patients in whom AB had been quantified in BAL. METHODS: BAL samples obtained from 578 participants between January 1997 and December 2014 were available for analysis. The processing of samples and the microscopic analysis were performed by a single expert and 76% of samples came from a single tertiary care hospital, allowing clinical and exposure data to be extracted from patient files...

To measure the toxic potential of asbestos fibers-a known cause of asbestosis, lung cancer, and malignant mesothelioma-asbestos minerals are generally first ground down to small fibers, but it is unknown whether the grinding condition itself changes the fiber toxicity. To evaluate this, we ground chrysotile ore with or without water for 5-30 min and quantified asbestos-induced reactive oxygen species generation in elicited murine peritoneal macrophages as an indicator of fiber toxicity. The toxicity of dry-ground fibers was higher than the toxicity of wet-ground fibers...

In Poland, the use of asbestos was banned in 1997 and asbestos plants have been closed since then. Despite their closure, cases of asbestos-related occupational diseases among former asbestos workers are still being recorded in the Central Register of Occupational Diseases. Between 2001 and 2014, there were 2726 asbestos-related illnesses, classified and reported as diseases associated with occupational exposure to asbestos. In 2000, Poland introduced a programme called Amiantus, targeted at former asbestos-processing plant workers...

Endometriosis remains a challenging condition for clinicians to treat. To improve our results we have to develop new treatment strategies based on pathophysiological mechanisms targeting the etiologic and pathogenic processes involved. It is essential to understand the inflammatory reaction and immunity incorporating the new molecular concepts. Inflammasome has been described as a multiprotein complex and is considered a key regulator of the innate and adaptive host response that surveys the cytosol and other compartments into the cell...

Anthophyllite is an amphibole form of asbestos historically used in only a limited number of products. No published resource currently exists that offers a complete overview of anthophyllite toxicity or of its effects on exposed human populations. We performed a review focusing on how anthophyllite toxicity was understood over time by conducting a comprehensive search of publicly available documents that discussed the use, mining, properties, toxicity, exposure and potential health effects of anthophyllite...

Lung tissue from 42 peritoneal mesothelioma cases was analyzed by light microscopy and scanning electron microscopy/energy dispersive spectrometry. There were 34 men and 8 women with a mean age of 61 ± 10 years. Also, 17% of cases had histologically confirmed asbestosis, and 26% had only parietal pleural plaques. The asbestos body count exceeded our normal range in 22 of 42 cases (52%). Cases with asbestos-related pulmonary disease had higher fiber burdens than those without. The vast majority of fibers were commercial amphiboles (amosite with lesser amounts of crocidolite)...

Idiopathic pulmonary fibrosis (IPF) is a specific form of chronic interstitial lung pneumonia associated with the histologic pattern of usual interstitial pneumonia (UIP). Although UIP is a distinct histologic lesion, this histologic pattern is not specific for IPF and can also be found in other diseases (e.g., connective tissue disease and asbestosis). Clinical features of IPF include progressive cough, dyspnea, restrictive ventilatory defect, and progressive fibrosis and destruction of the lung parenchyma...

Idiopathic pulmonary fibrosis (IPF) is a primary fibrosing pulmonary process. Due to the ineffectiveness of current therapeutic strategies and unfavorable prognosis, IPF is the most serious example of idiopathic interstitial lung diseases (ILD). Etiology and pathogenesis of this disorder have not been fully clarified yet; but it is anticipated, that the fibroproliferation is caused by the imbalance of reparative and immunologic processes in the genetically predisposed patients. Radiologically and histopathologically, IPF is characterized by specific pattern called usual interstitial pneumonia (UIP), however, this pattern is not fully typical in all cases, and, moreover, it could be seen in other ILD´s, e...
