Background: Occupational musculoskeletal injuries are prevalent in healthcare workers and are reported to be profession-specific. There is, however, a paucity of information around the injuries sustained from working as a podiatrist. This paper looks at the incidence of injury from working as a podiatrist, the aggravating factors to sustain these injuries and whether the changes in workload due to the COVID-19 pandemic altered the incidence., Methods: A modified work based musculoskeletal injury questionnaire was distributed in the UK via podiatry led social media platforms. Open and Closed questions explored the demographics of the sample, perceived injury 12 months prior to the COVID-19 pandemic and then 6 months into the lockdown. Pre and post COVID-19 data were analysed for differences and thematic analysis was included to categorise reported experiences., Results: 148 podiatrists representing 3 % of HCPC registered practitioners responded to the questionnaire. Employment status altered as a result of the COVID-19 pandemic with a 13 % reduction in those working full time. Environments also changed with domiciliary and telehealth significantly increasing (p > 0.00) and non-clinical roles being extended (p > 0.002). Pain frequency and intensity significantly (p > 0.04) increased as a result of the pandemic with shoulder pain being most frequent before lockdown altering to the neck during the lockdown. Two main themes were identified that were attributed to the causes of pain including physical demands and working in awkward spaces., Conclusions: Work-related musculoskeletal pain in podiatrists is common with the shoulder and neck being the most frequently affected. Changes in work practices due to the restrictions enforced from the COVID-19 pandemic increased the frequency and intensity of pain mostly associated with increased domiciliary and telehealth working environments., (© 2021.

This study aims to build a scale for musculoskeletal discomfort based on the self-reported musculoskeletal pain by individuals. For this, methods such as factorial analysis and item response theory were used. A sample of 1821 workers of a footwear industry participated in this study. The scale consists of four levels ranging from mild to maximum discomfort. In mild discomfort (level 60), pain symptoms are rare or frequent in regions such as cervical and trapezoidal area, low back, shoulders, wrists, ankles and feet. At level 70, rare or frequent symptoms affect regions of the upper and lower limbs. At level 80, frequent symptoms become common in the trunk and in most of the upper and lower limbs. At level 90, the symptoms become daily in elbows, thighs and knees. The scale showed signs of validity and proved useful for studies in ergonomics. Practitioner Summary: Methods such as factor analysis and item response theory were used to build a four-level musculoskeletal discomfort scale that can be useful to complement the screening process for workers with musculoskeletal pain. The scale shows signs of accuracy, in addition to validity and reliability. Abbreviations: WMSD: work-related musculoskeletal disorders; CTT: classic test theory; IRT: item response theory; KMO: Kaiser-Meyer-Olkin; PR: pain rarely; PO: pain often; PE: pain everyday; DIF: differential item functioning.

The life of medical specialists worldwide has dramatically changed due to the spread of the coronavirus disease 2019 (COVID-19) pandemic. Health care professionals (HCPs) have personally faced the outbreak by being on the first line of the battlefield with the disease and, as such, compose a significant number of people who have contracted COVID-19. We propose a classification and discuss the pathophysiology, clinical findings, and treatments and prevention of the occupational skin hazards COVID-19 poses to HCPs. The multivariate pattern of occupational skin diseases during the COVID-19 pandemic can be classified into four subgroups: mechanical skin injury, moisture-associated skin damage, contact reactions, and exacerbation of preexisting dermatoses. The clinical pattern is versatile, and the most affected skin sites were the ones in contact with the protective equipment. Dermatologists should recognize the plethora of HCPs' occupational skin reactions that are occurring during the COVID-19 pandemic and implement treatment and preventive strategies., Competing Interests: Conflict of interest The authors declare no conflict of interest., (Copyright © 2021 Elsevier Ltd.

Objective: Occupational exposure to agents in plastics and rubber manufacturing has been associated with elevated risk of certain cancers. We sought to evaluate cancer risk among workers employed in occupations and industries with these exposures as part of an ongoing surveillance programme in Ontario, Canada., Methods: The Occupational Disease Surveillance System (ODSS) cohort was established using workers' compensation claims data and includes 2.18 million workers employed from 1983 to 2014. Workers were followed for site-specific cancer diagnoses in the Ontario Cancer Registry through 2016. Cox proportional hazard models were used to estimate adjusted HR and 95% CI., Results: We identified 81 127 workers employed in plastics and rubber manufacturing industries or materials processing and product fabricating occupations. Compared with all other women in the ODSS, those in materials processing occupations had an elevated rate of lung cancer (HR 1.38, 95% CI 1.20 to 1.58) that was not observed among men. An elevated rate of breast cancer was observed among female labourers (HR 1.36, 95% CI 1.01 to 1.82) and moulders (HR 1.47, 95% CI 0.91 to 2.37) in plastics and rubber product fabricating occupations. Overall, elevated rates were observed for oesophageal, liver, stomach, prostate and kidney cancer in job-specific subgroups, including mixing and blending, bonding and cementing, and labouring. There was little evidence of association for lymphatic or haematopoietic cancers., Conclusions: Findings for lung and breast cancer in women are consistent with other studies and warrant further attention in Ontario. Given the relatively young age at end of follow-up, surveillance in these workers should continue as the cohort ages., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

Purpose of Review: Occupational exposures remain an underrecognized and preventable cause of lung disease in high-income countries. The present review highlights the emergence of cleaning-related respiratory disease and the re-emergence of silicosis as examples of trends in occupational lung diseases in the 21st century., Recent Findings: Employment trends, such as the shift from large-scale manufacturing to a service economy, the growth of the healthcare sector, and changing consumer products have changed the spectrum of work-related lung diseases. Following decades of progress in reducing traditional hazards such as silica in U.S. workplaces, cases of advanced silicosis have recently re-emerged with the production of engineered stone countertops. With growth in the healthcare and service sectors in the United States, cleaning products have become an important cause of work-related asthma and have recently been associated with an increased risk of chronic obstructive pulmonary disease (COPD) in women. However, these occupational lung diseases largely go unrecognized by practicing clinicians., Summary: The present article highlights how changes in the economy and work structure can lead to new patterns of inhalational workplace hazards and respiratory disease, including cleaning-related respiratory disease and silicosis. Pulmonary clinicians need to be able to recognize and diagnose these occupational lung diseases, which requires a high index of suspicion and a careful occupational history.

Purpose of Review: Occupational rhinitis (OR), an inflammatory disease of the nose, refers to any nasal symptoms reported to be work-related. The purpose of this review is to provide a current overview of the classification, diagnosis, and treatment of OR., Recent Findings: Occupational rhinitis (OR) can further be classified into allergic or non-allergic depending on the causative agent(s) and pathogenesis. Presenting symptoms are similar to non-OR including nasal congestion, anterior and posterior rhinorrhea, sneezing, and nasal itching. Despite its high prevalence in a spectrum of workplaces, OR is under reported as it is often considered a nuisance rather than a potential precursor to occupational asthma (OA). The diagnosis of OR is obfuscated as it is difficult to determine if this condition was caused by environmental determinants in or outside the workplace. Furthermore, workers may have a pre-existing history of allergic or non-allergic rhinitis leading the clinician and worker to overlook inciting agents in the workplace. In this case, a diagnosis of OR is still possible depending on the exposures but must be differentiated from work-exacerbated rhinitis. Further complicating the diagnosis of OR is the lack of evidence-based research focused on this condition as it is often trivialized due to the perception that it has an insignificant impact on the worker's health. The reality is that OR can have a significant impact on the worker's quality of life and is associated with a number of comorbidities including occupational asthma, recurrent sinusitis, headaches, eustachian tube dysfunction, and sleep disorders similar to non-occupational rhinitis. However, one significant difference between these disorders is that workers diagnosed with OR are eligible for worker's compensation. Treatment of OR involves avoidance of the inciting agent(s) and medications similar to those used to treat non-OR conditions. This review summarizes recent progresses on the etiology, risk factors, diagnosis, and therapy of OR. In addition, suggested areas of further research with potential targets for modifications in the workplace environment as well as therapeutic interventions will be discussed.

Aim: To estimate the occupational disease linked to temporary incapacity (not work-related illness)., Background: The under-reporting of occupational disease is a recognized problem in Europe., Methods: Cross-sectional study conducted in Spanish adult population using periods of temporary incapacity recorded in primary care during 2015. Rates of occupational disease were estimated using the García & Gadea study., Results: A total of 130,771 episodes of temporary incapacity were studied from 91,448 people, and 56,092 were women (61.3%). The overall prevalence rate was 2,096 and was higher in women (2,504) than in men (1,665) (p < 0.001). It was estimated that 6,580 (7.2%) could be suffering from an occupational disease. Musculoskeletal complaints were the commonest, affecting 75,165 people (82.2%). For the binary logistic regression, the dependent variable was the existence or lack of incapacity due to a musculoskeletal pathology. Age acts as a protective factor (adjusted OR = 0.978). The periods off work due to musculoskeletal complaints are lower in the first quarter of the year [OR > 1; p < 0.001]., Conclusions: 7.2% of the population was estimated to be off work due to an occupational disease. This estimate reflects the well-known under-reporting of occupational diseases which are dealt with by the Public Health System instead of specialized clinics., Implications for Nursing Management: The interdisciplinary role of the occupational health nurse makes it an adequate professional to detect the cases of occupational diseases in primary care settings. Occupational Health Nursing has been recognized by the managers as the most suitable professionals to carry out the screening of occupational diseases in Primary Care., (© 2019 John Wiley & Sons Ltd.)

This Essay discusses the theme of teachers' work and health in Brazil. The objectives are to describe the initial history of research on teachers' health, discuss elements leading to a consensus on the characterization of the group's work and principal health problems, and systematize the main strides and challenges. The Essay draws on more than two decades of research and practice in this field. Based on this experience, the authors identify the movements, the accumulated evidence, and prospects for future development. The elements brought to the discussion point to substantial growth in the field: the number of studies, the diversity and scope of topics, the groups of men and women teachers studied, and the experiences with application of the knowledge (programs and interventions). Despite these strides, the studies and practices still emphasize the individual and the disease, with little or no attention to work factors (work process and management) in the health/disease process. Issues pertaining to gender differences (in work and in health status) also remain invisible. There is little linkage between researchers and teachers' movements (a relevant characteristic of the first initiatives in the field). There are no public policies to regulate the workplace and work management. The contributions to the discussion provide insight for thought to assist the identification of critical nodes and analytical scenarios with the potential for progress in this field of research and intervention.

Background: Musculoskeletal symptoms often occur in more than one anatomical site. The present study aimed to define specific patterns of multisite musculoskeletal disorders and examine how these patterns are related to common psychological problems., Methods: Using the data from an interview-based health survey of 358 samples of the industrial manufacturing male employees, we derived major patterns of musculoskeletal complaints using latent class analysis and investigated its association with psychological problems score extracted from depression, anxiety, and stress measured by Depression/Anxiety/Stress Scale (DASS-21). Musculoskeletal disorders were assessed by Nordic Musculoskeletal Questionnaire (NMQ). The statistical analysis was carried out by Mplus 8., Results: Complaints in the lower back (42.1%) and neck (30.7%) had the highest prevalence, and in the hip (15.0%) and ankle (12.2%) the lowest. Three major patterns of musculoskeletal disorders were extracted using latent class analysis. Class 1 (12.9%) was characterized by a high rate of complaints in upper musculoskeletal sites, such as the neck, shoulder, and joints; class 2 (38.2%) was identified by a higher rate of complaints in the lower and upper back; and class 3 (48.9%) was marked by low rates of complaints in all musculoskeletal sites. After adjustment for confounding variables and specifying class 3 as the reference, it turned out that there was a statistically significant association between the psychological problems score and the chance of being in class 1 (OR = 2.47, 95% CI 1.66-3.68), but not a significant association with the chance of being in class 2 (OR = 1.51, 95% CI 0.83-2.72)., Conclusion: Musculoskeletal disorders can be summarized in the latent class-derived patterns in the adult study population and provide additional prognostics. Common psychological problems are significantly associated with the type of musculoskeletal disorder patterns. The findings in this study could be useful for dealing with prevention and treatment programs.

Introduction: The evaluation of occupational exposures allows to guide preventive strategies and to suggest adequate solutions., Aim: Identify occupational exposures and constrains among workers of private sector in Tunisia., Methods: A descriptive study including all companies of the private sector who are adhering to a service of occupational health of 17 Tunisian governorates. The survey was exhaustive for the services having less than 500 companies and by sampling for the services with more than 500.The data collection was based on data sheet completed by the occupational physician., Results: This investigation concerned 1653 companies employing 161 517 employees. The industrial sector represented 52.8 %.Small and medium-sized enterprises represented 92.6 % of the studied companies. Companies having a committee of Health and Safety at work represented 16.82 % and 22.14 % had a safety officer. Posturales constraints are the most represented exposures (56%) followed by gestural constraints (27%). Heavy lifting concerned 17% of workers. Exposure to noise represented the third professional nuisance, 23% of employees are exposed. The employees exposed to organic solvents were among 16695 (10.34 %), distributed on 685 companies., Conclusion: This study allowed us to identify and to rank the professional exposures and constrains in the Tunisian private sector. This could lead to improving targeted strategies of prevention occupational risks.

Bakgrunn: Det finnes lite forskning på forekomst av frostskader, både sivilt og militært. Prognosen og tidsforløpet ved slike skader har ikke tidligere vært undersøkt i større kohorter., Materiale Og Metode: Deltagerne var personer registrert i Forsvarets helseregister med kulde- og frostskade i tidsrommet 1.1.2010-31.12.2014. Data om diagnostikk, forløp og behandling ble innhentet fra i alt 460 personer ved hjelp av et spørreskjema. Svarprosenten på undersøkelsen var 66., Resultater: 397 av 460 personer (86,3 %) som var registrert med frostskade i Forsvarets helseregister bekreftet at de hadde hatt en kulde- og frostskade. 123 av 397 personene som svarte (30,1 %) anga at de hadde hatt blemmer, noe som gir mistanke om at de hadde pådratt seg annengrads frostskade. 225 av 397 (56,7 %) anga at de hadde hatt frostskade, men ikke blemmer. De aller fleste fikk frostskaden under feltøvelse/vinterøvelse (81,1 %), og ⅔ av de som pådro seg skader var vernepliktige. Langt de fleste hadde skader på fingre/hender eller tær/føtter (96,0 %). To av tre (69,8 %) hadde fortsatt plager fra sin frostskade mer enn to år etter skadetidspunktet., Fortolkning: Mange i militæret pådrar seg frostskader under tjenestegjøring. En femdel anga kroniske helseplager som påvirker arbeidsevnen. Kunnskap om forekomsten av frostskader hos militært mannskap er viktig for Forsvarets videre skadeforebyggende arbeid.

Background: This study provides direct evidence of cancer risk from low dose and dose rate occupational external radiation exposures., Methods: Cancer mortality and incidence were studied in relation to external radiation exposure in the National Registry for Radiation Workers. A cohort of 167,003 workers followed for an average of 32 years was analysed using Poisson regression methods., Results: Mortality and incidence risks were significantly raised for the group of all malignant neoplasms excluding leukaemia (ERR/Sv mortality = 0.28; 90%CI: 0.06, 0.53, ERR/Sv incidence = 0.28; 90%CI: 0.10, 0.48) but with narrower confidence bounds compared with the previous analysis of this cohort reflecting the increased statistical power from the additional 10 years of follow-up information. The linear trends in relative risk for both mortality and incidence of these cancers remained statistically significantly raised when information relating to cumulative doses above 100 mSv was excluded (ERR/Sv mortality = 1.42; 90%CI: 0.51, 2.38 and ERR/Sv incidence = 1.18; 90%CI: 0.47, 1.92)., Conclusions: This study improved the precision of the cancer risk estimates seen in the third analysis of the NRRW cohort. The overall results remain consistent with the risk estimates from the Life Span Study and those adopted in the current ICRP recommendations.

Background: Causative factors may be different for the very first onset of symptoms of the 'disease' of low back pain (LBP) than for ensuing episodes that occur after a pain-free period. This differentiation hinges on a life-time absence of low back pain at first onset and short-term absence for further episodes. In this systematic review, we explored whether researchers make these distinctions when investigating the causality of LBP., Methods: A literature search of PUBMED, CINAHL, and SCOPUS databases was performed from January 2010 until September 2016 using the search terms 'low back pain' or 'back pain' and 'risk factor' or 'caus*' or 'predict*' or 'onset' or 'first-time' or 'inception' or 'incidence'. Two reviewers extracted information on study design, types of episodes of back pain to distinguish the disease of LBP and recurring episodes, and also to determine the definitions of disease- or pain-free periods., Results: Thirty-three articles purporting to study causes of LBP were included. Upon scrutiny, 31 of the 33 articles were unclear as to what type of causality they were studying, that of the 'disease' or the episode, or a mere association with LBP. Only 9 studies used a prospective study design. Five studies appeared to investigate the onset of the disease of LBP, however, only one study truly captured the first incidence of LBP, which was the result of sports injury. Six appeared to study episodes but only one clearly related to the concept of episodes. Therefore, among those 11 studies, nine included both first-time LBP and episodes of LBP. Consequently, 22 studies related to the prevalence of LBP, as they probably included a mixture of first-time, recurring and ongoing episodes without distinction., Conclusion: Recent literature concerning the causality of LBP does not differentiate between the 'disease' of LBP and its recurring episodes mainly due to a lack of a clear definition of absence of LBP at baseline. Therefore, current research is not capable of providing a valid answer on this topic., Competing Interests: Not applicable.Not applicable.Associate Professor Bruce Walker AM is the Editor-in-Chief of Chiropractic & Manual Therapies and Professor Charlotte Leboeuf-Yde is Senior Editorial Advisor to the same journal.

Given the increased prevalence of cancer, respiratory diseases, and reproductive disorders, for which multifactorial origins are strongly suspected, the impact of the environment on the population represents a substantial public health challenge. Surveillance systems have become an essential public health decision-making tool. Networks have been constructed to facilitate the development of analyses of the multifactorial aspects of the relationships between occupational contexts and health. The aim of this study is to develop and present an approach for the optimal exploitation of observational databases to describe and improve the understanding of the (occupational) environment-health relationships, taking into account key multifactorial aspects. We have developed a spectral analysis (SA) approach that takes into account both the multi-exposure and dynamic natures of occupational health problems (OHPs) and related associations. The main results of this paper are to present the construction method of the "spectrum" and "spectrosome" of OHPs (range and structured list of occupational exposures) and describe the information contained therein with an illustrative example. The approach is illustrated using the case of non-Hodgkin lymphoma (NHL) from the French National Occupational Diseases Surveillance and Prevention Network database as a working example of an occupational disease. We found that the NHL spectrum includes 40 sets of occupational exposures characterized by important multi-exposures, especially solvent combinations or pesticide combinations, but also specific exposures such as polycyclic aromatic hydrocarbons, formaldehyde and ionizing radiation. These findings may be useful for surveillance and the assessment of occupational exposure related to health risks.

Background: Although data on industry and occupation (I&O) are important for understanding cancer risks, obtaining standardized data is challenging. This study describes the capture of specific I&O text and the ability of a web-based tool to translate text into standardized codes., Methods: Data on 62 525 cancers cases received from eight National Program of Cancer Registries (NPCR) states were submitted to a web-based coding tool developed by the National Institute for Occupational Safety and Health for translation into standardized I&O codes. We determined the percentage of sufficiently analyzable codes generated by the tool., Results: Using the web-based coding tool on data obtained from chart abstraction, the NPCR cancer registries achieved between 48% and 75% autocoding, but only 12-57% sufficiently analyzable codes., Conclusions: The ability to explore associations between work-related exposures and cancer is limited by current capture and coding of I&O data. Increased training of providers and registrars, as well as software enhancements, will improve the utility of I&O data., (© 2017 Wiley Periodicals, Inc.)

Background: This preliminary study evaluates a real-time syndromic surveillance system to track occupationally-related emergency room visits throughout New Jersey., Methods: Emergency Department (ED) chief complaint fields were evaluated from 79 of 80 hospitals in NJ in 2014, using work-related keywords and ICD-9 E-codes, to determine its ability to capture non-fatal work-related injuries. Sensitivity analysis and descriptive statistics, were used to evaluate and summarize the occupational injuries identified., Results: Overall, 11 919 (0.3%) possible work-related ED visits were identified from all ED visits. Events with the greatest number of ED visits were slips, trips, and falls (1679, 14%). Nature of injury included cuts, lacerations (1041, 9%). The part of the body most affected was the back (1414, 12%). This work-related classifier achieved a sensitivity of 5.4%, a specificity of 99.8%, and a PPV of 2.8%., Conclusions: This evaluation demonstrated that the syndromic surveillance reporting system can yield real-time knowledge of work-related injuries., (© 2017 Wiley Periodicals, Inc.)

Chronic obstructive pulmonary disease (COPD) most often results from the inhalation of toxic agents. Cigarette smoking still remains the principal cause but the pertinence of occupational COPD is now clearly established. After a brief overview of the epidemiology of this "other COPD", the clinical and functional characteristics are summarized, taking into account recent advances in this field. The combined effects of occupational exposure and tobacco are also considered, providing evidence of the need to continuously reinforce campaigns of education and prevention in occupational COPD., (Copyright © 2017 SPLF.

The aim of this paper was to define an unexplained non-classified polyneuropathy condition as a new neurological disease. This new diagnosis of occupation related polyneuropathy has been named as "WORKING HAND SYNDROME (WHS)."This study collected and compared clinic and electrophysiological analyze data from healthy controls, WHS patients, carpal tunnel syndrome (CTS) patients and polyneuropathy patients. The WHS patients presented to the clinic with pain, numbness, tingling, and burning sensations in their hands that increased significantly during rest and nighttime. However, there was no weakness in the muscles, and the deep tendon reflexes were normal in this disease. The patients had all been working in physically demanding jobs requiring the use of their hands/arms for at least 1 year, but no vibrating tools were used by the patients. All of the cases were men. I supposed that overload caused by an action repeated chronically by the hand/arm may impair the sensory nerves in mentioned hand/arm. In patients with these complaints, for a definitive diagnosis, similar diseases must be excluded. Nonetheless, the specific electrophysiological finding that the sural nerves are normal on the lower sides, as well as the occurrence of sensory axonal polyneuropathy in the sensory nerves without a significant effect on velocity and latency in the work-ups of the upper extremity are enough to make a diagnosis.In conclusion, WHS has been defined as a polyneuropathy and occupational disease. Patients with WHS present with pain, numbness, tingling, and burning sensations in their hands that increases significantly during rest and nighttime. They also use their arms/hands for jobs that require heavy labor. The neurological examinations of patients with WHS are normal. Only the sensory nerves in the upper extremities are affected. This article is suggested to serve as a resource for patients, health care professionals, and members of the neurology community at large.

Objective: To investigate the application and effectiveness evaluation of the standard of GBZ/T 229.1-2010 in practice, and to explore the applicability, aiming to provide technical evidence for the revision of GBZ/T 229.1-2010. Methods: There were 2 questionnaire surveys carried out in the study, including general survey and specific survey. Databases were established and data were input with Excel 2010 and Epidata version 3.1 software. SPSS version 19.0 software was used for data cleaning and statistical analysis. Results: The general survey received 100 questionnaires, with 43 from facilities and 57 from professional expertise. There were 59 questionnaires from occupational health technical service organizations held by government, and 11 from colleges and universities. The leading three jobs using GBZ/T 229.1-2010 were the occupational hazards evaluation for constructive project (69.0%) , lecturing/training (55.0%) , occupational hazards monitoring (50.0%) , respectively. The high frequency used contents of GBZ/T 229.1-2010 were the fourth part "classification" (67.0%) , the fifth part "the principles of classification management" (59.0%) , annex A "the correct use instructions" (52.0%) , respectively. In the results of feasibility, scores of the fourth part "classification" , the fifth part "the principles of classification management" , annex A "the correct use instructions" were 3.07, 3.03, 3.23, respectively. The parts needed to be modified as priories were the fourth part "classification" (22.0%) , the fifth part "the principles of classification management" (13.0%) , annex A "the correct use instructions" (12.0%) . The specific survey received 15 questionnaires, with 12 from the employers and 3 from occupational health technical service organizations. The awareness rate of GBZ/T 229.1-2010 among occupational health professionals was 83.3%. Classification results in the employers were used for guidance on improvement measures (66.7%) , health surveillance and monitoring (58.3%) , certification for occupational health and safety management system (33.3%) , occupational disease diagnosis (33.3%) , and personal protective equipment issued (33.3%) , etc. In the results of feasibility, scores of the content of free SiO(2), occupational exposure ratio, physical labor intensity level, classification of industrial dust, principles of classification management, annex A "the correct use instructions" were 5.00, 4.33, 5.00, 5.00, 3.67, 3.67, respectively. Conclusion: GBZ/T 229.1-2010 indicates that the standard is feasible and practical. But there are still some problems, such as classification of different kinds of industrial dusts at workplace, and the interaction of occupational exposure to industrial dusts and other hazards at workplace, etc.

Introduction: A 2009 Government Accounting Office (GAO) report, along with numerous published studies, documented that many workplace injuries are not recorded on employers' recordkeeping logs required by the Occupational Safety and Health Administration (OSHA) and consequently are under-reported to the Bureau of Labor Statistics (BLS), resulting in a substantial undercount of occupational injuries in the United States., Methods: OSHA conducted a Recordkeeping National Emphasis Program (NEP) from 2009 to 2012 to identify the extent and causes of unrecorded and incorrectly recorded occupational injuries and illnesses., Results: OSHA found recordkeeping violations in close to half of all facilities inspected. Employee interviews identified workers' fear of reprisal and employer disciplinary programs as the most important causes of under-reporting. Subsequent inspections in the poultry industry identified employer medical management policies that fostered both under-reporting and under-recording of workplace injuries and illnesses., Conclusions: OSHA corroborated previous research findings and identified onsite medical units as a potential new cause of both under-reporting and under-recording. Research is needed to better characterize and eliminate obstacles to the compilation of accurate occupational injury and illness data., Practical Applications: Occupational health professionals who work with high hazard industries where low injury rates are being recorded may wish to scrutinize recordkeeping practices carefully. This work suggests that, although many high-risk establishments manage recordkeeping with integrity, the lower the reported injury rate, the greater the likelihood of under-recording and under-reporting of work-related injuries and illnesses., (Published by Elsevier Ltd.)

The authors studied two types of morbidity among adults of Moscow over 2012-2014 - primary and occupational. Findings are that those levels in the city are significantly lower than the general in Russia. Over the studied period, the structure of both types of morbidity did not change, but there was a tendency to decrease both in total and in main entity classes of general and occupational diseases.

The International Classification of Radiographs of Pneumoconioses is the scheme worked out by the International Labour Office in Geneva (ILO), to register radiographic chest abnormalities in a well-ordered, reproducible and comparable way. It is used for diagnosing abnormalities caused by dust exposure. Guidelines for the use of the ILO International Classification of Radiographs of Pneumoconioses contain detailed information and recommendations on how to use the classification, as well as how the chest X-ray examination should be performed and recorded. To facilitate the diagnosis of observed abnormalities the classification is completed by the set of standard radiograms illustrating typical irregularities referring to lungs and pleura, included in the classification. The article presents the key information on classification and the most important amendments adopted in the 2000 and 2011 ILO guidelines revisions. These changes refer to radiographs quality assessment, the way of presenting abnormalities registered in standard radiographs (QUAD set, digital images) and registration of failures not related to dust exposure. Particularly important complements result from the development of radiological imaging techniques. They are concerned about the classification of radiographic images of the chest recorded digitally.

Aim: To examine the quality of manual job coding carried out by occupational health teams with access to a software application that provides assistance in job and business sector coding (CAPS). Methods: Data from a study conducted in an Occupational Health Service were used to examine the first-level coding of 1,495 jobs by occupational health teams according to the French job classification entitled “PSC- Professions and socio-professional categories” (INSEE, 2003 version). A second level of coding was also performed by an experienced coder and the first and second level codes were compared. Agreement between the two coding systems was studied using the kappa coefficient (κ) and frequencies were compared by Chi2 tests. Results: Missing data or incorrect codes were observed for 14.5% of social groups (1 digit) and 25.7% of job codes (4 digits). While agreement between the first two levels of PCS 2003 appeared to be satisfactory (κ=0.73 and κ=0.75), imbalances in reassignment flows were effectively noted. The divergent job code rate was 48.2%. Variation in the frequency of socio-occupational variables was as high as 8.6% after correcting for missing data and divergent codes. Conclusions: Compared with other studies, the use of the CAPS tool appeared to provide effective coding assistance. However, our results indicate that job coding based on PSC 2003 should be conducted using ancillary data by personnel trained in the use of this tool.

Occupational exposure to solvents, including n-hexane, has been associated with acquired color vision defects. Blue-yellow defects are most common and may be due to neurotoxicity or retinal damage. Acetone may potentiate the neurotoxicity of n-hexane. We present results on nonhexane solvent and hexane exposure and color vision from a cross-sectional study of 835 automotive repair workers in the San Francisco Bay Area, California (2007-2013). Cumulative exposure was estimated from self-reported work history, and color vision was assessed using the Lanthony desaturated D-15 panel test. Log-binomial regression was used to estimate prevalence ratios for color vision defects. Acquired color vision defects were present in 29% of participants, of which 70% were blue-yellow. Elevated prevalence ratios were found for nonhexane solvent exposure, with a maximum of 1.31 (95% confidence interval (CI): 0.86, 2.00) for blue-yellow. Among participants aged ≤50 years, the prevalence ratio for blue-yellow defects was 2.17 (95% CI: 1.03, 4.56) in the highest quartile of nonhexane solvent exposure and 1.62 (95% CI: 0.97, 2.72) in the highest category of exposure to hexane with acetone coexposure. Cumulative exposures to hexane and nonhexane solvents in the highest exposure categories were associated with elevated prevalence ratios for color vision defects in younger participants., (© The Author 2016.

This study discusses the inclusion of mental disorders as work-related diseases in occupational health policies in Brazil. Mental disorders first appeared as a group of occupational diseases in 1999. Establishing mental disorders as occupational diseases was a result of the confluence of several factors: a broader notion of health, a positive shift in public perception regarding preconceived judgements relating to mental disorders and the improvement in the process that defines social security benefit entitlements due to the implementation of a new methodology in 2007., (© The Author(s) 2016.)

Purpose: To compare the responses related to vocal symptoms in two versions of the Vocal Production Condition - Teacher (CPV-T) questionnaire, with responses on a Likert scale and a Visual Analog Scale (VAS), in order to evaluate which is the best measurement method., Methods: A cross-sectional observational study was conducted with teachers with voice disorders during the period from July 2011 to July 2012. All teachers answered the CPV-T in two versions: with answers on a 4-point Likert scale and on a 50-mm VAS. The answers related to vocal symptoms dimension were analyzed., Results: Most of the symptoms showed good (hoarseness, high-pitched voice, unstable voice, weak voice, effort when speaking, throat clearing, burning throat, and pain when speaking) or regular concordance (loss of voice, failing voice, low-pitched voice, vocal fatigue, dry throat, lump in the throat, secretion in the throat, pain when swallowing, difficulty swallowing, and dry cough)., Conclusion: The CPV-T questionnaire with answers on Likert scale proved to be more suitable than the VAS owing to the ease of understanding and interpretation, in addition to facilitating the input of answers for the researcher. Therefore, the Likert scale was chosen for the CPV-T, considering it to be validated as the method to measure the answers. The dimension of vocal aspects evaluated in the present study, the Voice Disorder Screening Index (ITDV), can be used in epidemiological studies to estimate the prevalence of vocal symptoms and in the Speech-Language Pathology and Audiology clinic routine or in monitoring teachers throughout their careers.

The insurance branch that covers the risk of occupational disability ranks among the most important private entities for offering security as far as the limitation or loss of one's ability to work is concerned. The financial risk of the insurer, the existential concerns and expectations of the claimant, as well as the legal framework and the need for a careful interdisciplinary evaluation, necessitate a professional review and assessment of the facts conducted with a sense of both responsibility and sensitivity. Carefully deliberated and sustainable decisions benefit both insurers and the insured. In order to achieve this, an opinion is required in many--and especially the more complex--cases from an external medical expert, which in turn can only be plausible and conclusive when based on a comprehensive review of the claimant's working environment and its particular (and often unique) requirements. This article is intended to increase the reader's understanding of the coherencies of workplace analysis and medical assessments, as required by insurance law and legislation. In addition, the article delivers valuable clues and guidance, both for medical experts and claims managers at insurance companies. Primarily, the claimant's occupation, as conceived in the terms and conditions of the insurance companies, is explained. The reader is then introduced to the various criteria to be considered when a claimant has several jobs at the same time, is self-employed, could be transferred to another job, is simply unable to commute to the workplace, or is prevented from working due to legal restrictions related to an illness. The article goes on to address the crucial aspect of how the degree of disability is to be measured under different circumstances, namely using the quantitative and the qualitative approach. As a reliable method for obtaining the essential data regarding the claimant's specific working conditions, which are required by both the medical expert and the insurance company's claims manager, the reader is provided with an insider's insights into on-site workplace analysis. The value of this pragmatic and proven method is subsequently demonstrated when the article addresses the often decisive part of the medical expert's assessment. In its conclusion the article points out the importance of workplace analysis to the entire process of evaluating occupational disability claims and the effort and monies to be saved by attaching value to thorough workplace analysis at an early stage.

With the revision of the German Ordinance on Occupational Diseases, skin cancer due to UV irradiation was amended as a new occupational disease to the list of occupational diseases in Germany. The new occupational disease BK 5103 has the following wording: "Squamous cell carcinoma or multiple actinic keratosis of the skin caused by natural UV irradiation". Actinic keratoses are to be considered as multiple according to this new occupational diseases if they occur as single lesions of more than five annually, or are confluent in an area > 4 cm(2) (field cancerization). It is estimated that more than 2.5 million employees are exposed to natural UV irradiation due to their work (outdoor workers) in Germany and therefore have an increased risk of skin cancer. In this article the medical and technical prerequisites which have to be fulfilled for this new occupational disease in Germany are introduced.

The different definitions of skin disease in medicine and in law are frequently confusing for dermatologists. While a skin disease may be defined medically referring to the definition of health by the WHO as a pathological condition of the skin leading to a disruption of the physical, mental and social well-being of the individual, legal definitions vary depending on the field of insurance law that is referred to. In the law of private health insurance, a skin disease is defined as an anomalous condition of the skin requiring medical treatment that exists independently of the subjective judgement of the insured person and needs to be objectively confirmed by a medical evaluation. In contrast, in the law of the social health insurance, the Federal Court of Social Justice defines disease as irregular physical or mental condition, deviating from the perception of a healthy human being that requires medical treatment or leads to inability to work. Substantial bodily disfigurement may be regarded as an irregular physical condition. In the law of the statutory accident insurance, occupational skin diseases are defined under clause 5101 of the occupational disease regulation as serious or repeatedly relapsing skin diseases that have forced a person to refrain from any work activities causal for the development, the aggravation or the recurrence of the disease. The Federal Court of Social Justice interprets the term "skin disease" from the protective purpose of the law, i.e. the protection against the economic and health consequences of the exposure to harmful agents and a thereby forced change of profession. This broad interpretation of the term "skin disease" leads to the recognition of diseases of the conjunctiva of the eye or diseases of the blood vessels of the skin due to cold damage as skin diseases according to clause 5101. For the correct treatment and possibly notification of occupational skin diseases in collaboration with various insurance carriers, dermatologists should be familiar not only with the medical definition, but also with these different legal definitions of skin disease.

In Germany over 2.5 million employees have an increased risk of skin cancer due to their occupational exposure to natural UV-irradiation. The medical consultation board "Occupational diseases" of the Ministry of Labor and Social affairs has investigated the association between occupational UV-irradiation and skin cancer risk and recommends to add the following new occupational disease into the appendix1 of the German ordinance on occupational diseases: "Squamous cell carcinoma and multiple actinic keratosis due to natural UV-irradiation". In this article we report in the view of the German Society of Occupational and Environmental Dermatology (ABD) and the German Statutory accident insurance (DGUV), whose criteria have to be fulfilled for the notification and recognition of an occupational skin cancer due to natural UV-irradiation., (© 2014 Deutsche Dermatologische Gesellschaft (DDG).

Problem: Occupational injuries and diseases are costly for companies and for society as a whole. This study estimates the overall costs of occupational injuries and diseases in Québec, both human and financial, during the period from 2005 to 2007., Method: The human capital method is used to estimate lost productivity. A health indicator (DALY) is used in combination with a value of statistical life (VSL) to estimate, in monetary terms, the pain and suffering costs resulting from occupational injuries., Results: The costs of occupational injuries and diseases occurring in a single year in Québec are estimated at $4.62 billion, on average, for the 2005-2007 period. Of this amount, approximately $1.78 billion is allocated to financial costs and $2.84 billion to human costs. The average cost per case is $38,355. In view of the limitations identified in the study, it can be argued that this is an underestimation of the costs. Result analysis allows the injury/disease descriptors and industries for which the costs are highest to be identified., Practical Applications: The results of these estimates are a relevant source of information for helping to determine research directions in OHS and prevention. The methodology used can be replicated for the purposes of estimating the costs of injuries and diseases in other populations., (Copyright © 2014 Elsevier Ltd. All rights reserved.)

Objectives: This paper sought to assess organizational safety practices at three different levels of hierarchical workplace structure and to examine their association with injury outcomes among construction apprentices., Methods: Using a cross-sectional sample of 1,775 construction apprentices, three measures of organizational safety practice were assessed: contractor-, steward-, and coworker-safety practice. Each safety practice measure was assessed using three similar questions (i.e., on-the-job safety commitment, following required or recommended safe work practices, and correcting unsafe work practices); the summed average of the responses ranged from 1 to 4, with a higher score indicating poorer safety practice. Outcome variables included the prevalence of four types of musculoskeletal pain (i.e., neck, shoulder, hand, and back pain) and injury-related absence., Results: In adjusted analyses, contractor-safety practice was associated with both hand pain (OR: 1.27, 95 % CI: 1.04, 1.54) and back pain (OR: 1.40, 95 % CI: 1.17, 1.68); coworker-safety practice was related to back pain (OR: 1.42, 95 % CI: 1.18, 1.71) and injury-related absence (OR: 1.36, 95 % CI: 1.11, 1.67). In an analysis that included all three safety practice measures simultaneously, the association between coworker-safety practice and injury-related absence remained significant (OR: 1.68, 95 % CI: 1.20, 2.37), whereas all other associations became non-significant., Conclusions: This study suggests that organizational safety practice, particularly coworker-safety practice, is associated with injury outcomes among construction apprentices.

The authors analyzed the health status of military personnel (males) of the Northern Fleet who did call-up military service (n = 420) and served on contract (n = 1370) in special diving positions in the Kola Arctic over the past few years. For the comparison of the rate of the decline of health level in different conditions of service the authors presented the averaged results of studies previously performed in the same period of time in the service personnel of coastal military units in the European North, troops from the surface ship crews and crew nuclear submarine. In the article there are considered the features of the primary disease and injury. Research and monitoring of causative-consecutive relationships between the features of military professional activity and the level and structure of primary morbidity rate allow to form the main directions of vocational rehabilitation for fleet specialists.

The range of diseases covered by workers' compensation is constantly expanding. However, new regulations are required for the recognition of occupational diseases (ODs) because OD types evolve with changes in industrial structures and working conditions. OD criteria are usually based on medical relevance, but they vary depending on the social security system and laws of each country. In addition, the proposed range and extent of work-relatedness vary depending on the socio-economic conditions of each country. The Labor Standards Act (LSA) and the Industrial Accident Compensation Insurance Act (IACIA) of Korea employ lists based on their requirements without listing causes and diseases separately. Despite a considerable reshuffle in 2003, the basic framework has been maintained for 50 yr, and many cases do not fit into the international disease classification system. Since July 1, 2013, Korea has expanded the range of occupational accidents to include occupational cancers and has implemented revised LSA and IACIA enforcement decrees. There have been improvements to OD recognition standards with the inclusion of additional or modified criteria, a revised and improved classification scheme for risk factors and ODs, and so on.

This study analyzed the characteristics of Brazilian postal workers that received sick leave benefits in 2008. The databases were from the Unified Benefits System (SUB) and the National Registry of Social Information (CNIS). The incidence rate was 556.5 benefits per 10,000 employees, and the leading causes of work-related sick leave were injuries, musculoskeletal disorders, and mental disorders. Areas most frequently reported in injuries were knees and legs, wrists and hands, ankles and feet, and shoulders and arms, with higher incidence rates in men. Women were more affected by musculoskeletal disorders and mental disorders. Average sick leave lasted longer in men, and the incidence of benefits increased with age. The States with the highest incidence rates were Mato Grosso do Sul, Goiás, and Santa Catarina, and security benefits averaged BRL 1,847.00. Postal work may involve additional risk of injuries to the limbs, due to the long distances carrying heavy weight, assault, and dog bites.

Aerosinusitis more frequently affects the frontal sinus than the maxillary sinus and mostly occurs during descent. Sinonasal diseases and anatomic variations leading to obstruction of paranasal sinus ventilation favor the development of aerosinusitis. This Continuing Medical Education (CME) article is based on selective literature searches of the PubMed database (search terms: "aerosinusitis", "barosinusitis", "barotrauma" AND "sinus", "barotrauma" AND "sinusitis", "sinusitis" AND "flying" OR "aviator"). Additionally, currently available monographs and further articles that could be identified based on the publication reviews were also included. In part 2, diagnostic measures, drug therapy, balloon dilatation and endoscopic sinus surgery are presented, along with a discussion regarding when flight attendants and pilots are able to resume their work. Endoscopic surgery to expand the natural drainage pathways of the affected sinuses with minimal surgical trauma to the healthy mucous membranes is largely successful.
