Non-occupational work-related diseases refer to health problems of multifactorial etiology, the occurrence, development and prognosis of which may be affected by work environment or by the way the work is performed but are not treated as occupational diseases under the applicable law. When analyzing their impact on labor market, it is necessary to also consider the employees' right to put in a claim for compensation due to the consequences of the occurrence of such diseases. Legal regulations as well as judicial decisions on the possibilities and methods of pursuing claims for compensation from an employer due to the occurrence of non-occupational work-related disease were analyzed. The analyzed legal regulations and judicial decisions referred to the regulations of the Labour Code, Civil Code and Resolution of the Supreme Court of 4 December 1987. The paper presents examples of non-occupational diseases considered to be work-related and conditions necessary to assert a claim by the employee at the court. Despite the lack of precise legal regulations in Poland, non-occupational work-related diseases may impact the legal situation of employees as well as employers. Employees are granted the right to claim for compensation from their employers in accordance with the Civil Code. Depending on the employer's legal responsibility, it is necessary to prove the meeting of the appropriate essential conditions to put in a claim for damage. Raising the employers' awareness of the legal and financial consequences shall support the occupational medicine services in intensifying their activity aimed at preventing all work-related diseases.

Objectives: The role of cross-reactive carbohydrate determinants (CCDs) in diagnostics of occupational allergy remains unclarified and its clinical relevance is still questioned. The aim of the study was to assess the frequency of positive response to CCDs in the subjects with suspected occupational allergy and the relationship between other diagnostic test results and final diagnosis. Material and Methods: The study group included 201 patients. They underwent clinical examination, skin prick test (SPT) to common and occupational allergens, specific serum immunoglobulin (sIgE) determinations, spirometry and specific inhalation challenge test. Moreover, sIgE to CCDs from bromelain was assessed in all subjects. Results: Occupational respiratory allergy was recognized in 64.3% of CCD-positive and 52.4% of CCD-negative patients. Positive SPT results to common and occupational allergens were found in 64.3% and 35.7% of CCD-positive subjects, respectively. In all subjects with CCDs, the sIgE to grass pollens as well as to occupational allergens were detected. The total IgE level > 100 kU/l was significantly associated with the presence of sIgE to CCDs. Conclusions: sIgE to CCDs were found in 7% of subjects suspected to suffer from occupational respiratory allergy. The presence of CCDs is not significantly associated with occupational respiratory allergy. It is also not more frequent in subjects reporting work-related respiratory symptoms in whom occupational allergy was not confirmed. The elevated total IgE level was related with CCD positivity. In patients with suspected occupational allergy, the presence of sIgE to CCDs in serum did not indicate the irrelevance of positive sIgE to occupational allergens.

Methemoglobinemia is a relatively rare, but potentially life-threating medical condition, which may be induced by application of topical anaesthetic agents commonly used during endoscopic procedure. The aim of our study was to assess the influence of lidocaine used prior to transesophageal echocardiography (TEE) on the blood level of methemoglobin in vivo. Additionally we attempted to establish the occurrence rate of clinically evident lidocaineinduced methemoglobinemia on the basis of data collected in our institution. We retrospectively analyzed patient records from 3,354 TEEs performed in our echocardiographic laboratory over the course of 13 years in search for clinically evident methemoglobinemia cases. Additionally, 18 consecutive patients referred for TEE were included in the prospective part of our analysis. Blood samples were tested before and 60 min after pre-TEE lidocaine anesthesia application. Information concerning concomitant conditions and pharmacotherapy were also obtained. In 3,354 patients who underwent TEE in our institution no cases of clinically evident methemoglobinemia occurred. In the prospective part of the study, none of 18 patients [16 (89 %) men, mean age 63 ± 13] was diagnosed with either clinical symptoms of methemoglobinemia or exceeded normal blood concentration of methemoglobin. Initial mean methemoglobin level was 0.5 ± 0.1 % with mild, statistically (but not clinically) significant rise to 0.6 ± 0.1 % after 60 min (p = 0.02). Among the analyzed factors only the relation between the proton pump inhibitors intake and methemoglobin blood level rise was identified as statistically relevant (p = 0.03). In adults, pre-TEE lidocaine anesthesia with recommended dosage results in significant increase in methemoglobin blood level, which however does not exceed normal values and does not result in clinically evident methemoglobinemia.

In Poland patients with psychiatric problems form a large group; in 2010 there were almost 1.5 million people for whom outpatient psychiatric care was provided, whereas approximately 200 thousand ill individuals were treated in 24-h psychiatric wards. Only 17% of the mentally disabled are professionally active. The results of many researches show that despite the detrimental influence of mental disorders on the employment (e.g., lower productivity, absenteeism, presenteism, increased risk of accidents at the workplace), professional activity can play a key role in the7stabilization of the mental state, it can also help in disease recovery. People with mental disorders are a social group that is at the higher risk of exclusion from the job market. The opinion prevailing among employers is that mentally ill individuals have decreased ability to conduct professional activity, and social attitudes towards them tend to be based on marking and stigmatizing. This review tackles the advantages of working during the illness, barriers which people with mental disorders face on the job market when they want to either start or continue work, and professional functioning of people with diagnosed depression (e.g., affective disorders) and schizophrenia (representing psychotic disorders). The analysis of existing data show that to improve the situation of mentally ill people present on the job market close cooperation between the representatives of various medical specializations is necessary, as well as their active participation in the process of social and professional rehabilitation of people affected by mental disorders.

Although specific sensitization to black tea was not observed in our study groups, cough and skin symptoms were significantly more frequently among the tea packers than in office workers. The irritant impact on the airways and the skin of tea dust and/or sensitization to moulds contaminating tea leaves are being suspected.

Over many years, allergy to natural rubber latex has been a major problem among health care workers (HCW). The diagnosis of occupational allergy requires methods of high diagnostic accuracy in view of certification implications (e.g., a sick worker quits a job). With the development of molecular methods, the frequency of application of recombinant allergens it the diagnostics of allergic diseases continues to increase. This paper reviews the applicability of laboratory tests which use recombinant allergens in the diagnostics of occupational allergy. The diagnosis of latex allergy is based on the presence of clinical symptoms linked with exposure to latex allergens, positive skin prick tests and detection of specific IgE antibodies to latex in serun. Moreover, in some cases specific challenge tests are conducted. The analysis of literature indicates that applying the panel of recombinant latex allergens in diagnostic tests, cross-reactivity can very likely be excluded and/or sensitization can be confirmed without the need for specific challenge tests, which in case of latex allergens carries a potential risk of aeneralized reactions.

The key activity in good practice of occupational medicine is to control, on a regular basis, the workers’ health and how it is affected by the work environment and – consequently – to provide the employers and employees with advice regarding the organization, ergonomics, physiology and psychology of work. Occupational medicine practitioners should remember that certain duties are performed both at work and at home. This issue is particularly important in preventive healthcare of pregnant working women. Taking the above into consideration, we reviewed the literature with respect to nuisance and occupational risk factors, which might be associated with professional and household duties. The research indicates the need to reduce activities that require frequent bending or lifting, put a women at risk of falling or cause excess occupational stress for pregnant women. We would like to draw the doctors’ attention to the possibility of exceeding a 4-hour limit of work at video display terminals and negative effects of low physical exercise and sitting for a long time both at work and at home. Since long working hours (over 40 h/week) affect the course of pregnancy negatively, total working time at work (including any additional jobs) and at home must be taken into account in the occupational risk assessment. To sum up, we emphasize that preventive healthcare of pregnant working women should mainly include education programmes. Women need to know how to perform their work safely and pay attention to the scope and frequency of household tasks (duties).

The system of occupational health care in Poland, based on occupational medicine service, takes care of almost 12.5 million employees subjected to over 4.5 million obligatory periodic medical check ups. This form of providing prophylactic care comes down to examinations dictated by legal regulations, whose scope is not oriented towards a comprehensive workers’ health assessment, but to the examination of the systems and organs critical to work-related dangers. Simultaneously, epidemiological data indicate a large number of chronic diseases, which may influence the professional activity, like hypertension or diabetes and a high percentage of patients not aware of their illness. Since patients participating in obligatory examinations usually feel healthy and do not use health care services on a daily basis, an occupational medicine physician has a unique opportunity to detect health disorders at an early stage, which can prevent the development of health complications affecting the condition of the patient, limiting their professional activity, but also causing additional costs of the health care system. The authors have proven the need to involve occupational medicine services in the prevention of chronic diseases and the need to introduce additional sources of financing for procedures enabling early detection of diseases the patient may not be aware of or control of the effectiveness of already diagnosed illnesses. They addressed the need to change the current legal form of establishing and announcing the range of examinations and directives for certifying the lack or presence of health contraindications to work to the specified and updated standards prepared by scientific research institutes and occupational medicine societies. System ochrony zdrowia pracujących w Polsce, oparty na świadczeniach realizowanych przez służbę medycyny pracy, obejmuje opieką niemal 12,5 mln pracowników. Rocznie wykonuje się u nich ponad 4,5 mln obowiązkowych badań okresowych. Tak sprawowana opieka profilaktyczna sprowadza się jednak najczęściej tylko do wykonywania badań określonych przepisami Kodeksu pracy. Ich zakres nie jest ukierunkowany na kompleksową ocenę stanu zdrowia pracujących, lecz na ocenę tych układów i narządów człowieka, które są krytyczne dla zagrożeń występujących na stanowisku pracy. Tymczasem dane epidemiologiczne wskazują na wysoką chorobowość z powodu chorób przewlekłych, które wpływają na utrzymywanie aktywności zawodowej (takich jak nadciśnienie tętnicze czy cukrzyca), oraz na znaczny odsetek chorych nieświadomych swojej choroby lub nieuzyskujących odpowiednich efektów terapeutycznych. Na obligatoryjne badania lekarskie zgłaszają się osoby przekonane o swoim zdrowiu, niekorzystające na co dzień z opieki zdrowotnej, dlatego lekarz medycyny pracy ma unikalną możliwość wykrycia zaburzeń w stanie zdrowia pracownika na ich wczesnym etapie. Dzięki temu może zapobiegać rozwojowi powikłań z jednej strony obciążających zdrowie samego pracownika, a z drugiej powodujących dodatkowe obciążenie finansowe dla całego systemu ochrony zdrowia. Konkludując, w artykule wskazano potrzebę zaangażowania służby medycyny pracy w profilaktykę chorób przewlekłych i związaną z tym konieczność wprowadzenia dodatkowych (oprócz pracodawców) źródeł finansowania działań profilaktycznych, umożliwiających wczesne wykrywanie stanów chorobowych, których pacjent nie jest świadomy, lub kontrolę skuteczności leczenia chorób już zdiagnozowanych. Podniesiono także potrzebę zmiany ustanawiania i publikowania zakresu badań oraz wytycznych do orzekania o braku lub istnieniu przeciwwskazań zdrowotnych do pracy z dotychczasowej formy prawnej na rzecz standardów określanych i na bieżąco publikowanych przez instytuty badawcze i towarzystwa naukowe działające w obszarze medycyny pracy.

Background: Hairdressers are occupationally exposed to many allergenic and irritating substances. Additionally, hairdressing apprentices are exposed to the same allergens as professional hairdressers, due to the fact that vocational training starts in the beginning of the education. This study was undertaken to investigate early occurrence of sensitization to occupational allergens in hairdressing apprentices before the onset of the vocational training. Material and Methods: Three hundred and seven hairdressing apprentices were assessed using a questionnaire and skin prick tests (SPTs) to common and occupational allergens. The level of total and serum specific immunoglobulin E (IgE) to occupational allergens was evaluated and spirometry was performed. Results: At least one skin and/or respiratory and/or conjunctival symptom was reported by 29.9% of subjects. Among subjects with at least one symptom, 28.2% of them were atopic whereas among 43.4% of them total IgE level was elevated. Atopy was found in 20% cases. In the case of one apprentice, positive SPT for paraphenylenediamine was found. Nearly 33% of apprentices had elevated total IgE level and 5 of them had specific IgE for occupational allergens. Conclusions: The study revealed that hairdressing apprentices might be sensitized to occupational allergens even before the beginning of vocational training, due to prior non-professional exposure to hairdressing agents. Furthermore, many of them report skin, respiratory and conjunctival symptoms, often connected with chronic disease diagnosis. Thus, candidates for hairdressers should be examined thoroughly before the start of the education and tests for allergy to hairdressing substances are indicated.

Evaluation of serum specific IgE is characterized by inadequate sensitivity, specificity and predictive value to take the place of specific inhalation challenge test in diagnostics of occupational respiratory allergy. Med Pr 2017;68(1):31-43.
