BACKGROUND: Fiberglass has a larger aerodynamic diameter and is less likely to be inhaled into the lungs. Further, it will be cleared even if it is mechanically broken into smaller pieces and inhaled into the lungs. Fiberglass lung disease has been well documented if long term exposure but was thought reversible and would not cause severe diseases. The diagnosis of fiberglass lung disease depends on exposure history and histopathological findings. However, the exact occupational exposure history is often difficult to identify because mixed substance exposure often occurs and fiberglass disease is not as well-known as asbestosis.
METHODS: A 66-year-old man had unexplained transudative pericardial effusion requiring pleural pericardial window operation twice at another medical center where asbestosis was told because of his self-reported long-term asbestosis exposure and the histopathological finding of a ferruginous body in his lung. Constrictive pericarditis developed two years later and resulted in congestive heart failure. Radical pericardiectomy combined with lung biopsy was performed following chest computed tomography imaging and the transudative nature of pericardial effusion not compatible with asbestosis. However, the histopathologic findings of his lung and pericardium at our hospital only showed chronic fibrosis without any asbestosis body. The patient\'s lung was found to be extremely fragile during a lung biopsy; histopathologic specimens were reviewed, and various fragments of fiberglass were found in the lung and pericardium. The patient\'s occupational exposure was carefully reevaluated, and he restated that he was only exposed to asbestosis for 1-2 years but was heavily exposed to fiberglass for more than 40 years. This misleading exposure history was mainly because he was only familiar with the dangers of asbestos. Since most fiberglass lung diseases are reversible and the symptoms of heart failure resolve soon after surgery, only observation was needed. Ten months after radical pericardiectomy, his symptoms, pleural effusion, and impaired pulmonary function eventually resolved.
CONCLUSIONS: Fiberglass could cause inflammation of the pericardium, resulting in pericardial effusion and constrictive pericarditis, which could be severe and require radical pericardiectomy. Exact exposure history and histopathological examinations are the key to diagnosis.

BACKGROUND: Questions concerning under-reporting of occupational diseases (OD) linked to asbestos exposure are regularly voiced in France. Monitoring of the French multicenter Asbestos-Related Disease Cohort (ARDCO), which ensures post-occupational medical surveillance of subjects having been exposed to asbestos, provides information on (1) the medico-legal steps taken following screening by computed tomography (CT) for benign thoracic diseases, and (2) recognition of OD as a causal factor in malignant diseases.
METHODS: OD recognition - and possible compensation - was analyzed in July 2021 among 13,289 volunteers in the cohort recruited between 2003 and 2005.
RESULTS: Fifteen percent of the subjects in the cohort were found to have at least one recognized asbestos-related OD (78.2% benign pleural disease, 10.3% asbestosis, 14.2% lung cancer, and 6.0% mesothelioma). Only 58% of pleural plaques reported by the radiologist who performed the CT resulted in their recognition as ODs. On a parallel track, 88.7% of the mesotheliomas identified based on French National health insurance data and 46.9% of lung cancers were recognized as ODs.
CONCLUSIONS: This study confirms the feasibility of a system designed to facilitate recognition, leading to possible compensation, of asbestos-related occupational diseases. The system could be improved by better training of the medical actors involved.

A variety of workplace exposures (organic or inorganic dusts as well as gases, fumes, or vapors) can cause diffuse interstitial lung disease. The latency period until onset of the disease can exceed 30 years. The disease course varies greatly and depends on the quantity of the inhaled substance and its fibrogenic effect. Pulmonary high-resolution computed tomography (HRCT) patterns do not differ significantly from those of interstitial lung diseases (ILD) of other etiologies. Therefore, without knowledge of the occupational history, work-related ILDs are often classified as idiopathic. In addition, there is increasing evidence in the recent literature that high exposure to silica dust can trigger autoimmune diseases (also involving the lungs). For this reason, a qualified occupational history is now an indispensable part of the interdisciplinary diagnosis of ILDs.
UNASSIGNED: Eine Vielzahl von Expositionen am Arbeitsplatz (organische bzw. anorganischen Stäube, Gase, Rauche oder Dämpfe) kann eine diffuse interstitielle Lungenerkrankung (ILD) verursachen. Die Latenzzeit bis zum Auftreten der Erkrankung kann mehr als 30 Jahre betragen. Der Verlauf ist sehr unterschiedlich und hängt von der Menge der eingeatmeten Substanz und deren fibrogener Wirkung ab. Die pulmonalen Muster in der hochauflösenden Computertomographie (HRCT) unterscheiden sich nicht wesentlich von ILD anderer Ursachen. Ohne Kenntnis der beruflichen Vorgeschichte werden arbeitsbedingte ILD daher oft als idiopathisch eingestuft. Aus diesem Grund ist eine qualifizierte Berufsanamnese heute ein unverzichtbarer Bestandteil der interdisziplinären Diagnose von ILD.

In the German Ordinance on Occupational Diseases (BKV), there are currently 82 occupational diseases listed, of which 18 partially or completely fall within the field of ENT medicine due to the associated health disorders. Noise-induced hearing loss is usually the focus of attention for the ENT specialist, but it has long since ceased to be the only occupational disease. In order to help uncover possible causalities between occupational noxious substances and diseases, it is important that physicians report their own observations and new scientific findings regarding suspected cases to the German Social Accident Insurance, especially in situations where cancer may be linked to occupational influences.
UNASSIGNED: In der deutschen Berufskrankheiten-Verordnung (BKV) sind unter den zzt. 82 gelisteten Berufskrankheiten 18 zu finden, die aufgrund der Gesundheitsstörungen teilweise oder ganz in das Fachgebiet der HNO-Heilkunde fallen. Die Lärmschwerhörigkeit steht für den HNO-Arzt/die HNO-Ärztin meist im Mittelpunkt, sie ist aber schon lange nicht mehr die einzige Berufskrankheit (BK). Eigene Beobachtungen und neue Erkenntnisse sollten im klinischen HNO-ärztlichen Alltag Anlass sein, gerade bei unklaren Fällen eine Verdachtsanzeige zu stellen, um mögliche Kausalitäten zwischen beruflichen Noxen und Erkrankung aufdecken zu helfen.

BACKGROUND: A pooled study on Italian asbestos cement plant cohorts observed mortality risk for asbestos-related diseases. This study analysed the mortality of workers cohort of an asbestos cement plant in Syracuse, Italy.
METHODS: Workers\' vital status and causes of death, during 1970-2018, were identified in regional health databases. Standardized mortality ratios (SMRs) by sex and temporal variables were calculated.
RESULTS: Of the 900 cohort\'s subjects (636 men, 259 women, 5 unknown sex), for 867 the vital ascertainment was possible: 505 died during study period. All-cause mortality is similarly to the expected among men and lower among women. Pleural and lung malignant neoplasms (MN) exceeded in men (SMR=27.1, SMR=1.95), retroperitoneal and peritoneal MN in both sexes, no cases of larynx MN were observed. Mortality excess for ovarian MN (SMR=1.5) and asbestosis in both sexes (men: SMR=431.9, women: SMR=116.6) were found.
CONCLUSIONS: Exceeding mortality from asbestos-related diseases, particularly in men was highlighted.

UNASSIGNED: The need for health surveillance of former workers exposed to asbestos was provided by law in Italy after the asbestos ban in 1992.
UNASSIGNED: We describe the results of the health surveillance of former workers exposed to asbestos, conducted over 27 years, from 1994 to 2020, at the Operative Unit of Occupational Medicine of the University Hospital of Bari.
UNASSIGNED: We adopted the health surveillance protocol, which was validated at the national level in 2018.
UNASSIGNED: A total of 1,405 former workers exposed to asbestos were examined. We proceeded with diagnosing pathologies in 339 cases (24% of the cohort subjected to surveillance), with diagnoses of some cases involving multiple pathologies. Specifically, pleural plaques were diagnosed in 49.2% of the 339 cases, asbestosis in 35.9%, malignant pleural mesothelioma (MPM) in 20.3%, mesothelioma of the vaginal tunic of the testis (MTVT) in 9.1%, lung cancer in 5.8%, and laryngeal cancer in 0.8%.
UNASSIGNED: Despite the 1992 asbestos ban, asbestos-related diseases remain a serious public health issue. It is important to establish criteria that ensure the health surveillance of formerly exposed workers minimizes costs, reduces the number of invasive examinations, and optimizes achievable results.

OBJECTIVE: In Italy, asbestos was used intensively until its ban in 1992, which was extended for asbestos cement factories until 1994. The aim of this study was to evaluate the dose-response between asbestos exposure and asbestosis mortality across a pool of Italian occupational cohorts, taking into account the presence of competing risks.
METHODS: Cohorts were followed for vital status and the cause of death was ascertained by a linkage with mortality registers. Cause-specific (CS) Cox-regression models were used to evaluate the dose-exposure relationship between asbestosis mortality and the time-dependent cumulative exposure index (CEI) to asbestos. Fine and Gray regression models were computed to assess the effect of competing risks of death.
RESULTS: The cohort included 12,963 asbestos cement workers. During the follow-up period (1960-2012), of a total of 6961 deaths, we observed 416 deaths attributed to asbestosis, 879 to lung cancer, 400 to primary pleural cancer, 135 to peritoneal cancer, and 1825 to diseases of the circulatory system. The CS model showed a strong association between CEI and asbestosis mortality. Dose-response models estimated an increasing trend in mortality even below a CEI of 25 ff/mL-years. Lung cancer and circulatory diseases were the main competing causes of death.
CONCLUSIONS: Asbestos exposure among Italian asbestos-cement workers has led to a very high number of deaths from asbestosis and asbestos-related diseases. The increasing risk trend associated with excess deaths, even at low exposure levels, suggests that the proposed limit values would not have been adequate to prevent disability and mortality from asbestosis.

OBJECTIVE: The aim of this study was to confirm the relationship between several parameters of exposure to asbestos and pleural plaques (PP) using data from a large cohort of retired workers occupationally exposed to asbestos in France.
METHODS: A large screening programme, including high-resolution CT (HRCT) examinations at inclusion and two other HRCT campaigns, was organised from 2003 to 2016 in four regions of France for voluntary, formerly asbestos-exposed workers. Exposure to asbestos has been evaluated by industrial hygienists based on the complete work history. The time since first exposure, the time since last exposure, Cumulative Exposure Index and maximum level of exposure to asbestos, were used in logistic regression using fractional polynomials to model the relationship with PP.
RESULTS: The study included 5392 subjects with at least one HRCT available. There was a significant non-linear effect of time since first exposure, time since last exposure and Cumulative Exposure Index to asbestos on the presence of PP. The risk of PP increased with increasing Cumulative Exposure Index to asbestos adjusted for time since first exposure, age and smoking status. Models also show that PP odds rise with increasing time since first exposure adjusted for cumulative index exposure, age and smoking status. PP odds decrease when time since last exposure increases.
CONCLUSIONS: The study provides new data on the link between asbestos exposure and the presence of PP using fractional polynomials with non-linear relationships for time exposure parameters and asbestos exposure parameters.

All six fiber types called asbestos can cause all the diseases related to exposure, including lung cancer. Known to the ancients, the modern history of asbestos hazards started in the 1890s with more and more data accumulating over time. Use increased exponentially in the middle of the 20th century with major use coming in construction and ship building. The recognition of asbestos as causing lung cancer dates to the early 1940s.
