[Assessment of Asbestos-related Occupational Diseases: Socio-medical and Legal Aspects]. / Sozialmedizinische und sozialjuristische Aspekte in der Zusammenhangsbegutachtung asbestbedingter Berufskrankheiten.

Occupational diseases are certain diseases designated as such by law. Whereas the medical conditions are described in guidelines, their recognition is based on judicial administrative procedures. Establishing causality is based on requirements of social law. The basic socio-legal concepts are mentioned and the principles of causality in asbestos-related occupational diseases are listed. Exemplary social court judgments are cited. Judgements may not infrequently differ from the medical point of view. The aim of this article is to describe the correct use of social medical understanding in order to carry out adequate assessment of occupational diseases, which implements the legal requirements.

Asbestosis and silicosis hospitalizations in Italy (2001-2015): results from the National Hospital Discharge Registry.

BACKGROUND: This work is aimed at evaluating the quality of Italian hospitalizations data about asbestosis and silicosis, assessing the impact of these diseases on the national health system and providing advice related to public health. METHODS: Italian hospital discharge data (2001-15) with diagnosis of asbestosis or silicosis were analysed by the multiple correspondence analysis and diseases epidemics were evaluated through hospitalization rates. RESULTS: Hospitalizations were concentrated in the northwestern area, referred mainly to males and oldest people, the most treated tumors were lung cancer and mesothelioma (for asbestosis) and cares were aimed at reducing symptoms and increasing blood oxygenation. Overall adjusted Italian hospitalization rates of asbestosis and silicosis were, respectively, 25.2 and 74.9 per 1 000 000 residents. With respect to asbestosis, hospitalizations treating silicosis reported doubled mortality (10.5 vs. 5.7%), longer stays (10.4 vs. 8.6 mean days) and older patients (77 vs. 72 years on average). Diseases rates reduced over time (with a steeper slope for silicosis) and in both fibroses increased hospital mortality (92.1% in asbestoses, 59.5% in silicoses) and percentage of urgent hospitalizations (116.0% in asbestoses, 56.6% in silicoses). CONCLUSION: Hospitalizations data regarding asbestosis and silicosis are consistent. Silicosis had a higher impact than asbestosis on the Italian health system. Although data show decreasing incidence of both fibroses, multiple correspondence analysis highlights that levels of illness severity were higher in silicosis and increased over time in both diseases. Further studies investigating the effectiveness of the current health surveillance programs concerning these diseases are suggested.

[Asbestosis and pleural plaques].

Asbestos was used in numerous products until its total ban in Denmark in 1988. The prevalence of asbestosis and pleural plaques does not yet appear to be falling. Unfortunately the statistics are unreliable due to errors in the Danish translation of the ICD-10 codes of the disease. In this review, clinical and radiologic diagnostic criteria of asbestosis and pleural plaques and recommendations for follow-up of patients are described. Typical changes on a high-resolution CT scan combined with relevant asbestos exposure is essential for the diagnosis. Asbestosis and pleural plaques are both notifiable in Denmark.

Occupational lung diseases in Australia.

Occupational exposures are an important determinant of respiratory health. International estimates note that about 15% of adult-onset asthma, 15% of chronic obstructive pulmonary disease and 10-30% of lung cancer may be attributable to hazardous occupational exposures. One-quarter of working asthmatics either have had their asthma caused by work or adversely affected by workplace conditions. Recently, cases of historical occupational lung diseases have been noted to occur with new exposures, such as cases of silicosis in workers fabricating kitchen benchtops from artificial stone products. Identification of an occupational cause of a lung disease can be difficult and requires maintaining a high index of suspicion. When an occupational lung disease is identified, this may facilitate a cure and help to protect coworkers. Currently, very little information is collected regarding actual cases of occupational lung diseases in Australia. Most assumptions about many occupational lung diseases are based on extrapolation from overseas data. This lack of information is a major impediment to development of targeted interventions and timely identification of new hazardous exposures. All employers, governments and health care providers in Australia have a responsibility to ensure that the highest possible standards are in place to protect workers' respiratory health.

Recomendaciones sobre el diagnóstico y manejo de la enfermedad pleural y pulmonar por asbesto / Recommendations for the Diagnosis and Management of Asbestos-Related Pleural and Pulmonary Disease

Asbesto, también conocido en España como amianto, es el término utilizado para nombrar a un conjunto de silicatos minerales que suelen romperse en fibras. Su uso ha comportado la aparición de numerosas enfermedades, especialmente pleuropulmonares, todas ellas caracterizadas por su prolongada latencia. El asbesto es, además, un carcinógeno del grupo IA reconocido por la OMS desde 1987. En España está prohibido desde 2002. La publicación en 2013 de la 3.a edición del protocolo de vigilancia sanitaria específica del amianto junto con la aparición de nuevas técnicas diagnósticas han motivado al grupo EROM de SEPAR a promover la elaboración de esta normativa que revisa aspectos clínicos, radiológicos y funcionales de las diferentes enfermedades relacionadas. También establece recomendaciones para el diagnóstico y seguimiento de los pacientes expuestos. Dichas recomendaciones han sido establecidas mediante sistema GRADE (AU)

Asbestos is the term used for a set of mineral silicates that tend to break up into fibers. Its use has been associated with numerous diseases affecting the lung and pleura in particular, all of which are characterized by their long period of latency. Asbestos, moreover, has been recognized by the WHO as a Group IA carcinogen since 1987 and its use was banned in Spain in 2002. The publication in 2013 of the 3rd edition of the specific asbestos health monitoring protocol, together with the development of new diagnostic techniques, prompted the SEPAR EROM group to sponsor publication of guidelines, which review the clinical, radiological and functional aspects of the different asbestos-related diseases. Recommendations have also been made for the diagnosis and follow-up of exposed patients. These recommendations were drawn up in accordance with the GRADE classification system (AU)

Exercise training for asbestos-related and other dust-related respiratory diseases: a randomised controlled trial.

BACKGROUND: The study aimed to determine the short and long-term effects of exercise training on exercise capacity and health-related quality of life (HRQoL) compared to usual care in people with dust-related pleural and interstitial respiratory diseases. No previous studies have specifically evaluated exercise training in this patient population. METHODS: Participants with a diagnosis of a dust-related respiratory disease including asbestosis and asbestos related pleural disease were recruited and randomised to an eight-week exercise training group (EG) or a control group (CG) of usual care. Six-minute walk distance (6MWD), St George's Respiratory Questionnaire (SGRQ) and Chronic Respiratory Disease Questionnaire (CRQ) were measured at baseline, eight weeks and 26 weeks by an assessor blinded to group allocation. RESULTS: Thirty-three of 35 male participants completed the study. Sixty-nine percent of participants had asbestos related pleural disease. At eight weeks, compared to the CG, the EG showed a significantly increased 6MWD (mean difference (95%CI)) 53 metres (32 to 74), improved SGRQ total score, -7 points (-13 to -1) and increased CRQ total score, 6.4 points (2.1 to 10.7). At 26 weeks significant between-group differences were maintained in 6MWD, 45 metres (17 to 73) and CRQ total score, 13.1 points (5.2 to 20.9). CONCLUSION: Exercise training improved short and long-term exercise capacity and HRQoL in people with dust-related pleural and interstitial respiratory diseases.

Malignant pleural mesothelioma: incidence, etiology, diagnosis, treatment, and occupational health.

BACKGROUND: The incidence of malignant mesothelioma in Germany is about 20 cases per million persons per year. Its association with asbestos exposure, usually occupational, has been unequivocally demonstrated. Even though the industrial use of asbestos was forbidden many years ago, new cases of mesothelioma continue to appear because of the long latency of the disease (median, 50 years). Its diagnosis and treatment still present a major challenge for ambulatory and in-hospital care and will do so for years to come. METHODS: This article is based on a selective review of the literature, along with data from the German Mesothelioma Register. RESULTS: 1397 people died of mesothelioma in Germany in 2010. A plateau in the incidence of the disease is predicted between 2015 and 2030. Most mesotheliomas arise from the pleura. The histological subtype and the Karnofsky score are the main prognostic factors. Only limited data are now available to guide treatment with a combination of the available methods (chemotherapy, surgery, radiotherapy). The prognosis is still poor, with a median survival time of only 12 months. Symptom control and the preservation of the patient's quality of life are the main aspects of care for patients with mesothelioma. CONCLUSION: The incidence of mesothelioma is not expected to drop in the next few years. The available treatments are chemotherapy, surgery, and radiotherapy. Specialized treatment centers now increasingly provide multimodal therapy for treatment of mesothelioma.

[What counselling to give to workers occupationally exposed to asbestos?]. / Quels dispositifs d'information pour les travailleurs ayant été exposés professionnellement à l'amiante?

When one approaches the issue of the follow-up of workers occupationally exposed to asbestos the first question to resolve is "what counselling to give?" This constitutes an essential first step because it allows people to decide whether or not they wish to accept the proposed follow up programme. The difficulty relates to the idea of exposure to a carcinogen. Facing this question is never easy and generates emotional responses that cannot be ignored. Therefore the content should include elements that allow an understanding of the diseased concerned, the risk (depending on the type of exposure), the benefits and limits of screening, and an awareness of the possible consequences of follow up. The programme should allow enough time for one to one discussion with a professional to consider all aspects. It may be necessary to meet for a second time. This counselling may be given, to subjects over 50 years old, in the framework of either the occupational health or social security services. The counselling of people exposed to asbestos justifies, in itself, a follow up programme and represents its main benefit. It should guarantee the worker's most elementary right: to decide for himself in full knowledge of the facts.

[Pilot data from the Spirale project -- follow-up of occupational respiratory exposures]. / Les dispositifs pilotes existants du suivi post-professionnel : Spirale.

INTRODUCTION: The medical follow-up of individuals who have had occupational exposures to potential respiratory hazards is little known and under-utilised. The Spirale program aims to deliver this intervention effectively to all potential beneficiaries. METHODS: Spirale was introduced in two stages; i) identification of occupational exposures to asbestos or wood dust through a postal questionnaire; ii) for those initially identified, confirmation of exposure through attendance at a health centre for examination and further medical follow-up as necessary. RESULTS: In 2007, Spirale contacted 50,662 men born between 1942 and 1943, living in 13 departments in France. The initial response rate was 24%, rising to 50% after reminders. Seventy-two percent of people were identified as possibly having been exposed; 50% to asbestos, 3% to wood dust and 19% reporting a mixed exposure. Among the 8641 people located, 3843 (44.5%) benefited from an evaluation of their exposure. In total, 73.4% of people had their exposure to asbestos confirmed and in 1751 (64.2%) this was at a level to justify follow-up. CONCLUSION: TheSpirale program largely achieved its objective of location and initiation of medical monitoring of people who have been exposed through their work to respiratory carcinogens. It should now be implemented throughout the country.

[Opinions and expectations of patients with health problems associated to asbestos exposure]. / Opiniones y expectativas de pacientes con enfermedades relacionadas con la exposición al amianto.

BACKGROUND: The prevalence of diseases related to asbestos exposure requires the development of monitoring programs and specific health care protocols. The aim of this study is to determine the opinions and expectations of former workers of an asbestos factory, in order to adapt the care process to the needs of the affected population, and to learn about the activity of the association that represents them. METHODS: Qualitative study. Focus groups with former employees of a corrugated asbestos factory, members of the association AVIDA (Seville). Recording and transcription of interviews. Discourse analysis with Nudist Vivo 1.0. RESULTS: All respondents have health problems, including asbestosis, lung cancer and mesothelioma. Through the association, they are involved in an ongoing process of negotiation with the public administration, to improve healthcare, achieve recognition as having an occupational disease and the payment of compensation. The lack of monitoring and continuity in care is designated as the major problem in the current care process. They welcome the creation of special care units, the good treatment received and the quality of technical instruments in the public health system. On the contrary, they criticize the difficulties in finding an accurate diagnosis, the lack of continuity of care, and the bureaucratic difficulties and lack of specific care directed to affected relatives. The participants' expectations highlight their intention to participate in the development of future programs and protocols. CONCLUSIONS: This study confirms the multifactor nature of diseases related to asbestos exposure and the importance of determining the needs and demands of the affected population in order to improve health care.

Mesothelioma and asbestosis in a young woman following occupational asbestos exposure: Short latency and long survival: Case Report.

A 27-year-old female white-collar worker was diagnosed in 1998 with mesothelioma eight and one-half years following first exposure as a bystander to debris in a site in which asbestos-containing building materials were being dismantled and rebuilding work took place. Prodromal back pain had been present for a year and a half. She underwent extrapleural pneumectomy and received an intrapleural infusion of cisplatin post-operatively. Exposure to asbestos was verified by contemporary reports and lung biopsy, which demonstrated asbestos bodies and microscopic interstitial fibrosis -conforming evidence for asbestosis. The patient is alive and well 12 years after diagnosis and 14 years after onset of symptoms. The combination of an extremely short latency period and long survival following occupational exposure to asbestos dust is unique.
