Recognition COVID-19 as an occupational disease in Poland - definition, criteria and recommendation.

A major challenge over the pandemic period was to establish the criteria for recognizing COVID-19 as an occupational disease. The European Center for Disease Prevention and Control has attempted to estimate the incidence of COVID-19 in individual occupational groups and economy sectors in the European Union and the United Kingdom, and to identify possible factors increasing the transmission of the virus at workplaces. Legal regulations of various countries in the world allow COVID-19 to be recognized as an accident at work and/or an occupational disease. In Poland, an occupational disease is defined as a disease caused by harmful factors occurring in the work environment or connected with performing a given job, included in the official list of occupational diseases. When assessing occupational exposure in the healthcare sector, it should be considered that healthcare workers include all persons in contact with patients or their biological material, as well as employees who are not medical professionals but who share a common space with patients due to the nature of their work. The latter group includes administrative and technical employees, control and rescue service workers, people supporting medical staff, and employees of nursing homes. In the case of non-medical occupations, the decision to recognize COVID-19 as an occupational disease should be made on an individual basis, after confirming a significant risk of contracting a SARS-CoV-2 virus infection at the workplace and in the absence of evidence of a non-occupational source of infection. An assessment of occupational exposure should always include evaluating the possibility of SARS-CoV-2 transmission. Med Pr Work Health Saf. 2023;74(5):435-42.

Concept of health surveillance programme for workers exposed to respirable crystalline silica at present and in the past.

In the paper authors present general assumptions of health surveillance programme concept for workers employed in respirable crystalline silica (RCS) exposure at present and in the past. There is no effective treatment for silicosis thus disease prevention is of paramount significance. For decades efforts of World Health Organization (WHO) and International Work Organization (ILO) have been focused on eliminating silicosis globally. Unfortunately silicosis is still one of the most lethal occupational diseases and the preventative programmes have not yet been successful. The authors identify main steps to complete an overview of RCS exposure and suggest lines of actions to be taken before launching the health surveillance programme. Introduction of the health surveillance programme would increase awareness of harmful health effects of the RCS exposure, emphasize the significance of preventive medical check-ups and early diagnostics of occupational diseases as well as the importance of using appropriate protective equipment. The programme development on a national level might be carried out with the cooperation of multiple backgrounds and institutions. This would allow for detailed planning, implementation, monitoring and effective evaluation of its results. Having a better and updated knowledge of silicosis epidemiology, early diagnostics, the possible sources of RCS occupational exposure and evaluation of undertaken preventive actions are crucial factors in disease prevention. The programme introduction would be of educational significance for all the stakeholders and the groups engaged in the project implementation, which would contribute to high effectiveness of the preventive activities and their improvement in the future.

Monkeypox (Mpox) and Occupational Exposure.

Recently, there has been a significant increase in interest in biological risk factors, which are increasingly perceived as an important problem in occupational medicine. Exposure to harmful biological agents may be associated with the deliberate use of microorganisms in the work process or with unintentional exposure resulting from the presence of biological risk factors in the work environment. Monkeypox (mpox) is a viral infectious disease that may afflict humans and non-human primates. Since May 2022, mpox has occurred in Europe, North and South America, Asia, Australia and Africa, with some 76,713 cases (75,822 in locations that have not historically reported mpox) and 29 total deaths reported to date. Between 2018 and 2021, several cases of mpox were reported worldwide in high-income countries (Israel, Singapore, United Kingdom, United States: Texas and Maryland). We conducted a literature search in PubMed and Google Scholar web databases for occupational exposure to mpox. The highest work-related risk for mpox transmission has been noted among healthcare professionals, people working with animals, and sex workers. There is general agreement that a paramount issue to avoid transmission of infection in occupational settings is an appropriate decontamination of often-touched surfaces and usage of appropriate personal protective equipment by the workers at high risk of infection. The group that should especially protect themselves and be educated in the field of early symptoms of the disease and prevention are dentists, who are often the first to detect the symptoms of the disease on the oral mucosa.

Epidemiology of silicosis reported to the central register of occupational diseases over last 20 years in Poland.

OBJECTIVES: The aim of the study was to investigate and assess the incidence of silicosis cases acknowledged as occupational diseases in Poland in 2000-2019. MATERIAL AND METHODS: The cases of all medically recognized pneumoconioses, including silicoses, certified as occupational diseases were studied. The records were extracted from the Central Register of Occupational Diseases, the only official Polish central electronic data base of occupational diseases. RESULTS: During the period 2000-2019, 2066 confirmed cases of silicoses and 10 665 cases of other pneumoconioses including asbestosis and coal workers' pneumoconiosis were reported to the Central Register of Occupational Diseases. Silicoses accounted for 12.8-21.2% of all pneumoconioses. The number of confirmed silicoses cases was growing along with the length of latency period and was the highest for the period of ≥40 years (513 cases). Over 70% of silicoses cases occurred after occupational exposure >20 years. The most workers who evolved silicosis were employed in manufacturing, predominantly casting of iron, mining and quarrying and construction. CONCLUSIONS: The number of confirmed cases of silicosis in Poland decreased in 2000-2019 but the disease still remains an important health problem. Prevention is crucial to reduce further disease incidence. The medical monitoring standards of exposed workers should be improved. Developing new diagnosing guidelines with the use of other imaging examinations, like high-resolution computed tomography, has to be considered. The analysis should contribute into the implementation of silicosis preventative programmes, both at the enterprise and national level. Int J Occup Med Environ Health. 2022;35(5):561-70.

[A dancer, a groomer, a folk artist and a viola player - case reports of occupational musculoskeletal and peripheral nervous system diseases]. / Tancerka, groomerka, twórczyni ludowa i altowiolistka ­ opisy przypadków chorób zawodowych ukladu ruchu i obwodowego ukladu nerwowego.

Work-related diseases of the musculoskeletal and the peripheral nervous system are classified as overload cumulative microtrauma diseases, resulting from chronic overload and/or damage of specific neuromusculoskeletal structures. Occupational activities which predispose to them are characterised by monotypy (repetition of movements during a significant part of the working shift). Authors described 4 cases of women with musculoskeletal and peripheral nervous system disorders qualified as occupational background just in the 2nd instance of medical certification. Detailed analysis of occupational exposure and medical interview with individual diagnostic approach allowed to determine the occupational etiology of diseases, regardless of non-occupational risk factors in some cases, even if the workstation was not common. Difficulties in estimating the probability of disease process induction on the background of occupational exposure are caused by frequent coexistence of non-occupational risk factors. The 2-tier system of certification provides an independent evaluation of medical history and occupational exposure. Med Pr. 2022;73(1):71-8.

The role of occupational health services in cancer prevention - which factors determine the implementation of preventive measures?

OBJECTIVES: Epidemiological data on cancer diseases are alarming. The workplace has become an increasingly important site for disseminating health information and implementing health promotion activities. Occupational medicine physicians (OMPs) have the opportunity to carry out primary and secondary preventive activities focused on civilization diseases, especially cancer. The aim of this study was to evaluate the potential of OMPs in cancer prevention, including the analysis of factors determining the implementation of preventive measures, as part of standard healthcare for employees. MATERIAL AND METHODS: The study was conducted among 362 OMPs. The interviews were carried out by the computer assisted telephone interview (CATI) method. RESULTS: Over 60% of the surveyed OMPs are ready to implement cancer preventive activities among employees. The doctors with the longest seniority in occupational health services are more likely to declare unwillingness to implement cancer preventive activities. Patient's consent, informing women about the program and adjusting the time of the medical visit are the most important conditions for introducing cancer prevention programs by OMPs. Neither seniority nor the number of examinations performed by a physician influenced the currently implemented cancer preventive activities as part of occupational health services (including the evaluation of cancer risk factors occurrence among employees). CONCLUSIONS: In Poland, OMPs are willing to implement cancer preventive activities among employees, but their current activity in this area is limited and needs development. The most specific actions should be addressed to doctors with the longest seniority in occupational health services, who are frequently unwilling to implement cancer preventive activities. Strengthening the preventive potential of Polish occupational health services requires a systemic approach to the scope and way of action of healthcare professionals.

Occupational Asthma Caused by Quaternary Ammonium Compounds: A Multicenter Cohort Study.

BACKGROUND: Quaternary ammonium compounds (QACs) are used extensively for cleaning and disinfection and have been documented in scattered reports as a cause of occupational asthma (OA) through bronchoprovocation tests (BPTs). OBJECTIVE: To examine the clinical, functional, and inflammatory profile of QAC-induced OA compared with OA caused by other low-molecular weight (LMW) agents. METHODS: The study was conducted in a retrospective multicenter cohort of 871 subjects with OA ascertained by a positive BPT. Subjects with QAC-induced OA (n = 22) were identified based on a positive BPT to QACs after exclusion of those challenged with cleaning products or disinfectants that contained other potential respiratory sensitizers. They were compared with 289 subjects with OA caused by other LMW agents. RESULTS: Most subjects with QAC-induced OA were working in the health care sector (n = 14). A twofold or greater increase in the postchallenge level of nonspecific bronchial hyperresponsiveness was recorded in eight of 11 subjects with QAC-induced OA (72.7%) and in 49.7% of those with OA caused by other LMW agents. Although sputum assessment was available in only eight subjects with QAC-induced OA, they showed a significantly greater median (interquartile) increase in sputum eosinophils (18.1% [range, 12.1% to 21.1%]) compared with those with OA caused by other LMW agents (2.0% [range, 0% to 5.2%]; P < .001). CONCLUSIONS: This study indicates that QAC-induced OA is associated with a highly eosinophilic pattern of airway response and provides further evidence supporting the sensitizing potential of QACs. The findings highlight the heterogeneous nature of the pathobiologic pathways involved in OA caused by LMW agents.

Evaluation of selected risk factors for cardiovascular diseases and diabetes as a background for the prevention program in occupational healthcare.

OBJECTIVES: Cardiovascular and metabolic disorders constitute major health problems in the working populations in Europe. The aim of this project was to evaluate the health condition of workers employed in a Polish research and medical institution, and then to establish the necessary preventive actions by creating a modern model of occupational healthcare integrated with civilization disease (CivD) prevention. MATERIAL AND METHODS: Overall, 100 workers voluntarily participated in a health program for CivD prevention during mandatory prophylactic examinations. Data from these examinations was collected in a system of electronic documentation to enable the analysis of the workers' health condition and risk factors of CivDs. RESULTS: Women accounted for 72% of the employees who voluntarily participated in the prevention program, and 80% of the subjects had university education. As regards the health condition, 27% of the patients had elevated systolic, and 23% diastolic, blood pressure, and 21% had an abnormal fasting glucose level. Stressful job was an important factor correlated with an excessive body mass index, diastolic blood pressure, as well as total and low-density lipoprotein cholesterol levels. Smoking, sedentary work and a lack of physical activity were significant factors for abdominal obesity. Generally, 94% of the program participants required some further interventions in lifestyle, diagnostics or treatment. CONCLUSIONS: Civilization disease prevention should focus on increasing physical activity both in leisure time and at the workplace as far as practicable. There is a need for implementing projects leading to occupational stress reduction and smoking cessation. Men as well as workers with vocational and elementary education need to be recruited for prevention programs dedicated to employees. Int J Occup Med Environ Health. 2021;34(3):403-13.

[Health protection of employees against SARS-CoV-2 coronavirus infection causing the COVID-19 disease - the current state of knowledge and recommendations]. / Ochrona zdrowia pracujacych przed zakazeniem koronawirusem SARS-CoV-2 wywolujacym COVID-19 ­ aktualny stan wiedzy i zalecenia.

The COVID-19 pandemic, despite the restrictions and preventive measures applied, has rapidly spread and reached Poland. The adaptation to the dynamically changing epidemiological situation requires a prompt implementation of effective preventive measures. The aim of the publication is to provide current knowledge to all persons involved in the preventive care system, i.e., employees, employers and professionals of occupational medicine, about the epidemiological situation related to SARS­CoV- 2, as well as recommendations and possible solutions. In order to analyze these issues, a review of literature was conducted based on medical research databases: PubMed, SCOPUS, and the Web of Science Core Collection. The literature was supplemented with studies found on websites of the Ministry of Health and the World Health Organization. Data on the cases of and deaths due to COVID-19 come from reports provided by the Ministry of Health, data published on the websites of the European Center for Disease Prevention and Control, and ourworldindata.org. By the time of submitting the publication, 34 154 cases and 1444 deaths due to coronavirus had been recorded in Poland. Data from published studies suggest that the virus is mainly transmitted via droplets or through contact with contaminated objects and surfaces. Therefore, in the absence of an effective vaccine, preventive actions are based mainly on strategies that minimize the risk of pathogen transmission. In addition to discussing the current epidemiological situation, diagnostic procedures, risk groups and COVID-19 characteristics, the paper presents recommendations and proposed solutions for employers and employees regarding the prevention of SARS­CoV- 2, along with currently applicable laws and recommendations on employee prophylactic examinations during the pandemic. Subsequently, COVID-19 was discussed in the aspect of an occupational disease and other health threats related to the pandemics. The epidemiological situation regarding coronavirus indicates the need to take immediate and effective actions to minimize infection transmission among employees, and to develop procedures for a quick and effective ability to locate the COVID-19 outbreaks in workplaces.

[Recommendations for performing specific inhalation challenge tests: Polish experience in relation to the European Respiratory Society guideliness]. / Wytyczne do przeprowadzania swoistych wziewnych testów prowokacyjnych: stanowisko Europejskiego Towarzystwa Chorób Ukladu Oddechowego (ERS) w kontekscie polskich doswiadczen.

A diagnosis of occupational diseases implicates some medical and legal consequences; therefore, the most specific and objective methods are needed in the diagnostic process. Specific inhalation challenge (SIC) tests currently play an irreplaceable role in diagnosing allergic airway diseases (e.g., allergic rhinitis, asthma) as well as allergic conjunctivitis and systemic reactions, also the occupational ones. In 2014, a team of the European Respiratory Society experts published a statement that provides practical recommendations for performing SIC tests in diagnosing occupational asthma. In the current publication, the authors discuss the European guidelines in the context of Polish experience of the reference center - the Department of Occupational Diseases and Environmental Health, the Nofer Institute of Occupational Medicine in Lódz. The article describes the procedures and diagnostic criteria employed during SIC tests in diagnosing occupational asthma. Med Pr. 2020;71(3):381-97.

Mannitol vs. methacholine in the evaluation of airway responsiveness in bakers' asthma.

OBJECTIVES: Various indirect or direct airway challenge tests are used to measure nonspecific bronchial hyper-responsiveness (NSBHR). The evaluation of NSBHR in diagnosing occupational asthma (OA) is performed, e.g., to monitor the specific inhalation challenge test (SICT). The aim of this study was to preliminarily compare the results of methacholine and mannitol inhalation challenge tests in SICT monitoring in bakers with work-related airway symptoms. MATERIAL AND METHODS: Four bakery workers with a suspicion of OA underwent single-blind placebo-controlled SICTs involving workplace allergens, accompanied by the evaluation of NSBHR with mannitol and methacholine, both before and after SICTs. Clinical examinations, spirometry tests, skin prick tests (SPTs) to common aeroallergens and occupational allergens, as well as tests to determine serum specific IgE antibodies to occupational aeroallergens were also performed. RESULTS: Positive SPTs results to occupational aeroallergens were found in all bakery workers, and specific IgE antibodies to flour were detected in 2 subjects. Three patients displayed positive SICT reactions. In all of these 3 patients, airway responsiveness to methacholine increased significantly. In 2 patients, airway reaction to mannitol was significant, whereas in 1 subject there was no increase in NSBHR after mannitol inhalation. The patient with a negative SICT result did not reveal any changes in NSBHR before and after the test, either to methacholine or mannitol. CONCLUSIONS: The data obtained by the authors show that there is no clear correlation between the methacholine and mannitol inhalation challenge tests in SICT monitoring. Preliminary results indicate the need for further investigations to evaluate the usefulness of the mannitol challenge test in the diagnostics of OA. Int J Occup Med Environ Health. 2020;33(2):235-9.

Bronchial Response to High and Low Molecular Weight Occupational Inhalant Allergens.

PURPOSE: Occupational asthma may be induced by high- or low-molecular weight allergens (HMWA or LMWA, respectively). The study was conducted to compare the pattern of bronchial response in 200 HMWA-induced asthmatics (n = 130) and LMWA-induced asthmatics (n = 70). METHODS: The study participants underwent a single-blind, placebo-controlled specific inhalation challenge (SIC) with workplace allergens, accompanied by evaluation of non-specific bronchial hyperresponsiveness (NSBHR) with methacholine before and after the SIC. RESULTS: A single early bronchial response more frequently occurred in HMWA-induced asthmatics than in LMWA-induced asthmatics (86.2% vs. 20%). An isolated late bronchial response or atypical patterns were more frequently observed in LMWA-induced asthmatics than in LMWA-induced asthmatics (45.7% vs. 3.8% or 34.3% vs. 10%, respectively). Baseline NSBHR before SIC was more often detected in LMWA-induced asthmatics than in HMWA-induced asthmatics (81.4% vs. 54.6%), and the median value of the provocation concentration of methacholine was relevantly lower in these patients before and after SIC. A significant 3-fold increase in NSBHR after SIC was observed more often in LMWA-induced asthmatics than in HMWA-induced asthmatics (82.8% vs. 66.1%). In addition, compared to LMWA-induced asthmatics, HMWA-induced asthmatics were older, were more frequently active smokers, showed lower level of NSBHR, and more frequently continued their work in harmful occupational exposure. CONCLUSIONS: The results of this study suggest that HMWA-induced asthmatics may have milder clinical courses and that there is a possibility of job continuation despite asthma exacerbation requiring medical surveillance.

[Workers' view on the preventive needs for civilization diseases' in prophylactic care taken on employees]. / Potrzeba dzialan prewencyjnych dotyczacych chorób cywilizacyjnych w opiece profilaktycznej sprawowanej przez sluzbe medycyny pracy ­ opinia pracujacych.

BACKGROUND: Every year in Poland almost 5 million prophylactic examinations (PEs) are carried out by occupational medicine specialists (OMPs) among workers, for the purposes envisaged in the Polish Labour Code. The aim of this study was to collect workers' opinions on the possible extension of these check-ups in the field of prophylaxis and prevention of civilization diseases (CivDs), focusing also on the "healthy lifestyle" recommendations. MATERIAL AND METHODS: The study group comprised 325 employees who filled out an anonymous questionnaire containing questions about the possible extension of the PE scope for CivD and cancer prophylaxis. During medical check-ups, evaluation of the incidental glucose (IG) and total cholesterol (TCh) levels, waist circumference measurement and electrocardiography (ECG) were proposed. The respondents were asked about the most interesting issues for discussing with OMPs. RESULTS: Screening tests for some cancers (69.5%) and risk factors for CivDs (61.5%) were indicated as the most interesting topics to discuss with OMPs. The possibility for evaluating the levels of IG and TCh during PEs was approved by approx. 94.8% and 95.3% of the respondents, respectively. Almost 96% accepted having ECG and 80% agreed to waist circumference measurement. As many as 89.5% of the respondents supported the idea of organizing physical activities at their workplaces, and 77.8% were eager to learn about "healthy lifestyles" during training sessions conducted at their workplaces. CONCLUSIONS: Restricting the aim of PEs just to certifying the ability to work, or identifying certain medical contraindications, means losing a chance for implementing the prophylaxis and prevention of diseases' development among active working subjects. The kinds of activities proposed by the authors of this publication have been approved by the employees. Med Pr. 2019;70(4):425-33.

Food processing and occupational respiratory allergy- An EAACI position paper.

Occupational exposure to foods is responsible for up to 25% of cases of occupational asthma and rhinitis. Animal and vegetable high-molecular-weight proteins present in aerosolized foods during food processing, additives, preservatives, antioxidants, and food contaminants are the main inhalant allergen sources. Most agents typically cause IgE-mediated allergic reactions, causing a distinct form of food allergy (Class 3 food allergy). The allergenicity of a food protein, allergen exposure levels, and atopy are important risk factors. Diagnosis relies on a thorough medical and occupational history, functional assessment, assessment of sensitization, including component-resolved diagnostics where appropriate, and in selected cases specific inhalation tests. Exposure assessment, including allergen determination, is a cornerstone for establishing preventive measures. Management includes allergen exposure avoidance or reduction (second best option), pharmacological treatment, assessment of impairment, and worker's compensation. Further studies are needed to identify and characterize major food allergens and define occupational exposure limits, evaluate the relative contribution of respiratory versus cutaneous sensitization to food antigens, evaluate the role of raw versus cooked food in influencing risk, and define the absolute or relative contraindication of patients with ingestion-related food allergy, pollinosis, or oral allergy syndrome continuing to work with exposure to aerosolized food allergens.

[The prophylactic operational model integrated with occupational healthcare - Prophylactic of some types of cancers among women]. / Model dzialan profilaktycznych zintegrowany z opieka profilaktyczna nad pracownikami ­ zapobieganie niektórym typom nowotworów wsród kobiet.

Periodical medical examinations are mandatory for employees in Poland. This rule makes a unique opportunity during occupational health services for implementation of prophylactic activities focused on early diagnosis of various diseases, including cancers. Epidemiological data about cancers is alarming and what is more, further increase in development of cancers is being predicted in population overall. The highest incidence of cancers in the case of Polish women belongs to breast cancer (21.7% of diagnosed cancers in general), while the morbidity rate for uterine cancer, ovarian cancer and cervical cancer amounts to 7.4%, 4.7% and 3.5%, respectively. The aim of this study was to elaborate an algorithm of prophylactic activities integrated with the occupational healthcare system, based on medical literature review and guidelines concerning prophylaxis of selected cancers. Polish cancers' prophylaxis programs related to risk factors were presented in this publication and practical indications for occupational healthcare physicians were worked out. Med Pr 2018;69(4):439-455.

Can Periodical Examinations of Employees Be Useful in Detection of Glycaemia Impairment and Improving Patients' Adherence to Medical Recommendations?

Worldwide epidemiological data indicates insufficient diagnosis of diabetes as an increasing public health problem. In the search for solutions to this disadvantageous situation, occupational medicine health services seem to open up a unique opportunity to recognize some abnormalities in the early stages, especially among the asymptomatic working-age population. 316 workers underwent obligatory prophylactic examinations. In patients with twice assayed FGL ≥ 126 mg/dL (7.0 mmol/L) an additional intervention was implemented, including further diagnostic processes and therapy in General Practice (GP), followed by examination by an occupational health specialist within 3 months. The diagnosis of previously unknown diabetes was established among 2.5% of examined workers. All patients referred to the GP due to detected glycaemia impairment visited their doctor and finished the diagnostic process, took up therapy constrained by the occupational health physician to show the effects of intervention within 3 months. Prophylactic medical check-ups allow improved compliance and medical surveillance over glycaemia impairment in patients with prediabetes states, unknown diabetes or uncontrolled clinical course of diabetes. Considering fasting glucose level during mandatory prophylactic examination helps effective prevention of diabetes and its complications and thus provides public health system benefits.

Is it possible to improve compliance in hypertension and reduce therapeutic inertia of physicians by mandatory periodic examinations of workers?

BACKGROUND: Due to high prevalence, insufficient recognition, and ineffective treatment, hypertension (HT) still remains a major medical and socio-economic problem. There is a real necessity to develop effective prophylaxis for cardiovascular disorders (CVD), based on strategies that support compliance during long-term therapy. The Polish scheme of occupational health services with mandatory periodical employee check-ups creates a unique opportunity for effective HT prophylaxis. As a result, visiting a doctor is required not only due to health ailments but also by law, which is especially important for those feeling well. It enables an improvement in tertiary prevention, including actions taken not only by the doctors of the occupa-tional health services, but also by the physicians in charge of treating the patients. AIM: Evaluation of the usefulness of mandatory health check-ups of employees concerning frequency of diagnosis and im-provement of treatment outcomes of HT. METHODS: The study group comprised 1010 Polish workers referred by their employers for mandatory medical examinations. All of the study participants filled in a questionnaire focused on self-assessment of their health, current blood pressure (BP) mea-surements, and in cases where HT had been previously detected - compliance with medical recommendations. Then in the doctor's office BP measurements were taken twice. Workers who fulfilled a criterion indicating a need for intervention were educated on optimal diet, physical activity, and risk factors for CVD. They also received medical instructions for three-step action. The first recommendation: measure BP three times a day for one week and record the results. The second: visit a gen-eral practitioner (GP) for a professional assessment of those results. The third: re-visit the occupational health physician within three months. The criterion for intervention was prior HT and a mean of two BP measurements ≥ 180/110 mmHg - in each case, or ≥ 140/90 mmHg - in the case of occupational exposure to risk factors for CVD. RESULTS: The mean age of the study participants was 41.7 years (similar in both genders). A previous diagnosis of HT was declared by 20.1% of patients. 11% of patients involved in the intervention did not comply with medical advice. The current HT therapy of all of the subjects with HT (100% of those with abnormal BP, who visited their GP) was modified. CONCLUSIONS: Prophylactic medical check-ups of workers gives improved compliance and medical surveillance of HT in patients with an uncontrolled clinical course of this disease. Obligations and periodic examinations encourage both patients and physicians to improve compliance and reduce the risk of therapeutic inertia.

Spirometric and hygienic criteria in recognition of occupational COPD in Poland - A retrospective analysis of medical records.

OBJECTIVES: Chronic obstructive pulmonary disease (COPD) may be work-related. It has been estimated that 15% of the population burden of COPD is attributable to occupational exposure. However, in Poland COPD is rarely recognized as an occupational disease. The aim of the study has been to analyze the causes of the low prevalence of work-related COPD in the context of the existing criteria as well as to analyze which part of the assessment - clinical or hygienic one - is responsible for such a low rate of occupational COPD recognitions. MATERIAL AND METHODS: The study group included 150 patients hospitalized with a suspicion of occupational COPD. Each patient underwent a clinical examination, spirometry and reversibility test using bronchodilator. Moreover, hygienic evaluation of work conditions was performed in all the considered cases. RESULTS: In the case of the patients who fulfilled the criteria for COPD diagnosis in accordance with the Global Initiative for Chronic Obstructive Lung Disease (GOLD) occupational origins of the disease, the disease was not recognized because 24.1% of the individuals did not meet spirometric criteria included in a definition of COPD in the Polish list of occupational diseases, while 27.8% of the individuals did not fulfill the criterion of a documented exposure to dusts and irritant gases. None of these criteria was fulfilled by 42.6% of the patients. CONCLUSIONS: In our country, both clinical and hygienic criteria result in limitations in recognition of occupational COPD. There is the need to establish new guidelines for the recognition of COPD as a compensable disease in Poland. Int J Occup Med Environ Health 2018;31(2):139-150.

[Occupational cancers - Epidemiology and certification]. / Choroby nowotworowe pochodzenia zawodowego ­ epidemiologia i aspekty orzecznicze.

The etiology of cancer is multifactorial. Malignant tumors caused by factors occurring in the work environment, classified as carcinogenic in humans, can be recognized as an occupational disease. Analysis of epidemiological data indicates a significant underestimation of occupational cancer, mainly due to long latency period of these diseases. This publication provides guidance to certify occupational etiology of malignant tumors, based on the reviews of existing legislation and medical literature, as well as on the experience of their authors. The publication presents the epidemiology of cancers, including occupational cancers, risk factors, occupational carcinogens and presents the principles of occupational cancer certification. Med Pr 2018;69(1):93-108.
