Objectives: To update and extend the examination of cancer incidence in a cohort of Danish firefighters, now adding 7 years of follow-up and 2766 additional firefighters. The primary focus was directed toward cancer sites that recently contributed to the hazard evaluation conducted by the International Agency for Research on Cancer (IARC)., Methods: The updated cohort consisted of 11,827 male Danish firefighters who were followed up for cancer from 1968 to 2021. Cohort cancer morbidity was compared with a working population reference group, and standardized incidence ratios (SIR) were used for estimation of relative risks, along with 95% confidence intervals (95% CI)., Results: Among full-time firefighters, SIR of skin melanoma was 1.30 (95% CI: 1.02-1.66), and SIR = 1.37 (95% CI: 1.02-1.85) for over 5 years of employment. Slightly positive associations were also observed for cancer of the urinary bladder (SIR = 1.16; 95% CI: 0.93-1.45), prostate (SIR = 1.11; 95% CI: 0.97-1.28), and testis (SIR = 1.11; 95% CI: 0.75-1.63)., Conclusions: This updated study provides evidence indicating an elevated risk of skin melanoma in firefighters. Consistent with IARC's evaluation, we also identified positive associations for urinary bladder, prostate, and testis cancer. In contrast, our findings did not suggest an increased risk of colon cancer, non-Hodgkin lymphoma, and mesothelioma. The latter may be due to small numbers in our still relatively young cohort. Continuous follow-up for cancer in firefighters is warranted, including assessment of influence from surveillance bias., (© 2024 Wiley Periodicals LLC.)

Introduction: The seafood industry is the largest industry in Greenland. Work-related diseases and accidents appear to constitute health risks in this sector. The aim was to describe the prevalence of work-related diseases and accidents among workers in the seafood industry in Greenland., Methods: Data from 311 workers included a questionnaire, lung function measurements, skin prick tests, blood samples, clinical examinations, personal inhalable dust samples and stationary dust measurements. Accident risk was evaluated by work site observations and safety walks. Statistical analyses included mean values and percentage distribution., Results: Exposure levels were highest in shrimp production; 16.1% were sensitised to snow crab, 10.1% to shrimp and 0.3% to fish; 5.2% had probable occupational asthma. Regarding accidents, the annual incidence rate per 100 workers was 10.3%., Conclusions: Workers in the seafood industry in Greenland have a high prevalence of sensitisation to work-related allergens and occupational asthma closely related to high exposures to shrimp and snow crab allergens. The rate of severe workplace injuries was high. Preventive measures are required., Funding: The Health Science Research Council; The Work Environment Council of Greenland; The Greenlandic Workers' Union; Greenland Business Association; Royal Greenland; Polar Seafood; The BANK of Greenland; The Danish Working Environment Research Fund., Trial Registration: The Scientific Ethical Committee for Greenland (2015-11317); The Danish Data Protection Agency, the Central Denmark Region (2012-58-006)., (Articles published in the DMJ are “open access”.

Objective: Firefighters are exposed to numerous respiratory hazards, but large studies on the risk of pulmonary disease are scarce. The objective of this study was to examine incidence of asthma and chronic obstructive pulmonary disease (COPD) in a nationwide cohort of Danish firefighters., Methods: We used individual historical employment records on 11 968 Danish male firefighters primarily supplied by trade unions and fire agencies. Furthermore, we used the Supplementary Pension Fund Register to form an occupational reference group consisting of military employees. Information on respiratory incidence was retrieved from the nationwide Danish National Patient Registry. Age and calendar time standardised incidence ratio (SIR) and Poisson regression analyses (incidence rate ratio) were used for estimation of risks, including 95% CIs., Results: Compared with military employees, the overall age and calendar-time adjusted risk for asthma was significantly increased among full-time firefighters (SIR=1.58, 95% CI 1.32 to 1.88), but not among part-time/volunteer firefighters. Full-time firefighters' risk for asthma did not vary by duration of employment. No consistent evidence of an increased risk for chronic obstructive pulmonary disease was detected., Conclusion: Danish firefighters have an increased risk of asthma, but the causes, whether occupational or not, remain to be established., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2018.

Purpose: Occupational exposure of firefighters involves a complex range of potential health threats from toxic chemicals, shift work, extreme heat, physical and emotional strain. The aim of this study is to examine overall and disease-specific mortality among Danish firefighters., Methods: Through systematic collection of personnel and membership records from employers and trade unions, past and present male Danish firefighters were identified (n = 11,775). Using the unique Danish personal identification number, information on additional employment, vital status and cause of death was linked to each member of the cohort from the Supplementary Pension Fund Register, the Danish Civil Registration System and the Danish Register of Causes of Death. Standardized mortality ratios (SMRs) were calculated for specific causes of death using rates for two reference groups, a random sample of the male working population (n = 262,168) and the military (n = 396,739), respectively., Results: Overall mortality was significantly reduced among the firefighters compared to both the sample of the working population and the military (SMR 0.74, 95% CI 0.69-0.78 and SMR 0.88, 95% CI 0.83-0.93). Further, the SMRs for endocrine diseases, mental disorders, non-traffic related accidents and other external causes were significantly lower against both reference groups. Death from stomach cancer was significantly increased among the full time firefighters, while part time/volunteer workers shared a significant increase in prostate cancer death compared to both references., Conclusions: Despite potential exposure to several occupational hazards, male Danish firefighters have a lower mortality than both the Danish working population in general and Danish military employees.

Introduction: Skin cancer may, in some cases, be caused by occupational exposures. The aim of this study was to investigate the prevalence of and exposures leading to occupationally induced skin cancers in Denmark during a ten-year period., Material and Methods: The study is a descriptive, register-based study comprising all patients with recognized occupational malignant and premalignant skin conditions in Denmark in the 01/01 2000-31/12 2009 period. Data were obtained from The National Board of Industrial Injuries and comprise information about diagnosis, occupational and domestic exposure, anatomic localization, occupation, degree of permanent disability, age and sex., Results: A total of 36 patients were recognized as occupational skin cancer cases. The mean age was 61 years (44-75 years), 31 men and five women. The most frequent diagnosis was basal cell carcinoma followed by squamous cell carcinoma. No cases of malignant melanoma were recognized. The primary risk factor for development of occupational skin cancer was ultraviolet (UV) exposure during outdoor working., Conclusion: Data based on recognized cases of occupational skin cancer during a ten-year period in Denmark show that non-melanoma skin cancer was the most frequent diagnosis, while the primary risk factor was UV radiation in outdoor occupations. A total of 36 cases were reported over a period of ten years, and underreporting may be suspected. The purpose of the present study was to raise the awareness of occupational skin cancer, and on the basis of existing data to contribute to criteria for the diagnosis of occupational skin cancer., Funding: not relevant., Trial Registration: not relevant.

The purpose was to assess disorders related to disaster victim identification (DVI) in a group of Danish forensic personnel that had performed disaster victim identification in Thailand after the 2004 tsunami. All individuals from the DVI team were screened using a questionnaire to identify disorders presenting in relation to DVI work in Thailand. All participants who had a positive screening result were examined clinically by an occupational physician and had a standard lung function test. Individuals with skin disorders were examined by a dermatologist and a skin patch was performed. Individuals with respiratory disorders were evaluated by a specialists in pulmonary medicine, based on the results of an extended lung function test and a skin prick test. Out of the 165 persons that worked with DVI in Thailand, 152 (92%) answered the questionnaire, and 24 underwent subsequent clinical examination. On examination, five persons were found to have skin disorders and four had airway disorders associated with the DVI work in Thailand. The allergy tests gave no support to the conditions being caused by exposure to disinfectants or other specific chemicals in any of the examined individuals. Working in disaster areas may cause or aggravate skin and airway disorders. It is suggested that an assessment of risk is performed before sending personnel abroad to challenging working conditions, and that a health check is carried out upon their return.

Purpose: The aim of this study was to create a job-exposure matrix (JEM) for wet work. A JEM is a tool used to assess exposure to potential health hazards in occupational epidemiological studies. It can be used when counselling concerning job change/job choice, as a medico-legal tool when recognizing diseases as occupational and when planning interventions regarding prevention of, in this case, occupational hand eczema. Methods: The study population was based on results from national surveys on working environment performed by the National Research Centre for the Working Environment in Denmark in 2000, 2005, and 2010 (National Research Centre for the Working Environment). We assessed responses on questions regarding wet hands, glove wear and total wet work. For the JEM a cutoff of 2 h total wet work/day was chosen as the exposure measurement. The proportion of responses of 2 h total wet work/day in each profession is illustrated as a number between 0 and 1 equal to 0–100% of the responses. Results: Total wet work was most frequent among cleaners (domestic, office, and hotel cleaning), butchers and fishmongers, cooks, beauticians (hairdressers, barbers, related work) and health care workers (home-based personal workers, dentists, dental assistants). Regarding differences between sexes we found that indifferent of age and profession, women had 78% higher odds of having wet work. Conclusion: We found that wet work as an exposure varies among professions depending on whether wet hands or glove wear is assessed. A JEM is a useful tool to assess the extent of the exposure, wet work, independent of prior perceptions of classical wet work professions. [ABSTRACT FROM AUTHOR]

Summary: Background: Wet work is an important risk factor for occupational hand eczema. Objectives: To examine the effect of job change in workers with occupational hand eczema caused by wet work, and to evaluate the dose–response relationship between intensity of wet work and eczema. Method: The study is based on a subgroup (n = 954) from a descriptive, registry‐based study including all participants with occupational hand eczema caused by wet work recognized by the Danish Labour Market Insurance Authority in 2010 and 2011. A follow‐up questionnaire was sent out 4–5 years later (response 58%). Results: Change of profession and being outside the labour market had a positive effect on healing and improvement of hand eczema. Inverse dose–response relationships were found between the amount of time spent with wet hands at work and healing (p = 0.001) and improvement (p < 0.001), and between the frequency of hand washing at work and healing (p = 0.013) and improvement (p < 0.001). Conclusions: Leaving the profession has a positive effect on eczema; however, even minor changes in exposure to wet work were associated with healing and improvement. This information has implications with respect to advice given to patients with occupational hand eczema caused by wet work. [ABSTRACT FROM AUTHOR]

Summary: Background: An inverse relationship between disease severity and health‐related quality of life (HR‐QoL) in patients with hand eczema is well established, but modifying effects of demographic variables have been less well studied. Objective: To identify the influence of metropolitan versus non‐metropolitan residence on the relationship between disease severity and HR‐QoL in patients with occupational hand eczema. Methods: The city of Copenhagen and the rest of Zealand were defined as metropolitan and non‐metropolitan areas, respectively. Participants were 773 persons with occupational hand eczema. A questionnaire on the severity of hand eczema and HR‐QoL was sent to all participants. Results: The odds for reporting moderate to high severity of occupational hand eczema were significantly lower in the metropolitan population than in the non‐metropolitan population [odds ratio (OR): 0.42; 95%CI: 0.23–0.75], whereas low dermatology‐related quality of life was more prevalent in metropolitan than in non‐metropolitan patients (OR: 1.31; 95%CI: 0.83–2.05), indicating that hand eczema had a more pronounced negative effect in metropolitan patients, in spite of less severe eczema. Conclusion: Our data indicate that area of residence has a modifying effect on the relationship between disease severity and HR‐QoL, with a more negative impact on HR‐QoL in metropolitan than in non‐metropolitan areas. This information is important with respect to fully appreciating the burden of occupational hand eczema. [ABSTRACT FROM AUTHOR]

Background Patch testing is mandatory for diagnosing contact dermatitis. It is, however, crucial that patients understand and remember the result of the test. Objectives The aim of our study was to evaluate the impact of patch testing with respect to patients' ability to remember patch test results and the results of natural rubber latex protein allergy after 2 years. Methods One hundred and ninety-nine patients diagnosed with relevant occupational epoxy or rubber chemical contact allergy, or allergy to natural rubber latex protein, were invited to participate in a questionnaire study about their knowledge of contact allergies after 2 years. Results The response rate was 75%. Of the respondents, 13% did not remember their occupational contact allergy to rubber chemicals or epoxy. Ability to remember was not significantly influenced by sex or Dermatology Life Quality Index, but was decreased by age >60 years ( p < 0.01). Of patients with an additional contact allergy, <36% remembered this correctly. Of patients allergic to natural rubber latex proteins, 50% remembered this correctly. Conclusions The impact of patch testing depends on the patients' ability to understand and remember the results of the test. Attention should be drawn to the importance of this, and patients with increased need for information should be identified. [ABSTRACT FROM AUTHOR]

Background Skin disorders accounted for one third of all recognised occupational diseases in Denmark in 2010. Wet work is a risk factor for the development of occupational hand eczema. The consequences of occupational hand eczema include sick leave, loss of job and impaired quality of life. Objectives The aim of the present study was to investigate exposures related to cleaning and the effect of an evidence-based educational intervention on the prevention of hand eczema among hospital cleaners. Patients/Materials/Methods The intervention consisted of a 1 hr course in hand protective behaviour. All full-time cleaners working at Bispebjerg Hospital in January 2013 were invited to participate. The outcome measures were self-reported skin behaviour, exposures, knowledge of skin protection and hand eczema severity index ( HECSI). Results One hundred and five cleaners were invited to participate, of these 86 (82%) were included. At follow-up after 3 months there was a shift towards fewer daily hand washings and hand disinfections ( p < 0.001 and p = 0.001 respectively). The number of correct answers to the knowledge questions rose from 6.3 to 7.3 ( p = 0.006). The mean HECSI score decreased from 2.8 to 1.8 at follow-up ( p = 0.002). Conclusions Data indicates a positive effect of a low-cost on-site educational intervention for hospital cleaners. [ABSTRACT FROM AUTHOR]

Background Skin diseases are the most commonly recognized occupational diseases in Denmark, and occupational contact dermatitis (OCD) comprises ∼95% of all cases. Objectives To prevent occupational contact dermatitis, it is important to specifically identify exposures and work routines related to outbreak of the disease. The aim of this study was to give an overview of exposures for patients with occupational contact dermatitis in Denmark in 2010, and relate this to line of work and disease severity. Material and methods The study was a descriptive, register-based study including patients with recognized occupational contact dermatitis in Denmark in 2010. Data were obtained from the National Board of Industrial Injuries in Denmark, and comprised information about the skin disease as well as the occupation/industry of employment and exposures. Results One thousand five hundred and four patients, 1020 women and 484 men, were included in the study. Irritant contact dermatitis accounted for 70% of all cases; 68% of these were caused by wet work. Forty-six per cent of all patients were employed either in the healthcare sector, in cleaning, or as kitchen workers. Among contact allergies, the most common were to rubber additives from gloves and epoxy in patients employed in the windmill industry. Conclusion The data are important for planning preventive efforts in the future. The workers in the healthcare sector, kitchen workers and cleaners constitute almost half of all cases, and future preventive efforts should be directed at these occupations. [ABSTRACT FROM AUTHOR]

The article reports on the result of the study which assesses the role of smoking and occupational exposure to organic solvents in the development of chronic bronchitis (CB) among men. The study was participated by 3387 men at the Glostrup Hospital in the University of Copenhagen where a health questionnaire was given to each participant. It provides a comparison on the health condition of men smoking and exposed to occupational organic solvents compared to those who were nonsmokers. It reveals that tobacco smoking and long-term exposure to organic solvents are the major factors that contribute to the prevalence of the respiratory disease.
