Opis:: The purpose of the research is to prepare a mathematical and numerical model for the phenomenon of heat transfer during cryopreservation. In the paper, two popular methods, slow freezing and vitrification, are compared. Furthermore, the basic model of thermal processes is supplemented by the phenomenon of phase transitions. To determine the temperature distribution during cryopreservation processes, one uses the heat transfer equation proposed by Pennes. An integral part of the energy equation is the substitute thermal capacity (STC) performed according to the concept named one domain method (fixed domain method), The numerical model is developed using the finite difference method (FDM) connected with directed interval arithmetic. The final part of the article contains the results of numerical simulations.

Opis:: Objectives: Viral hepatitis is the second most often identified infectious illness acquired at work and it is mostly registered among health care personnel. This group of workers is at greater risk of exposure to blood and bloodborne pathogens, including hepatitis B and C viruses. The aims of this study were to evaluate the efficacy of methods promoting work safety in healthcare settings, to assess the frequency of exposures in the last 12 months prior to the study and to determine a rate of reporting them to appropriate authorities. Methods: A total of 1138 Polish healthcare workers were interviewed during the study period (between 2009 and 2010). Results: Sustaining accidental occupational percutaneous exposure during last 12 months was declared by 242 workers (21% of the whole group). Only in 146 cases these incidents were reported to authorities. Exposure incidents were associated with self-perception of high risk of exposure (OR = 3.69, p = 0.0027), employment in out-patient (vs. hospital-based) healthcare setting (OR = 1.71, p = 0.0089), conviction that the level of information about bloodborne infections conveyed at work was insufficient, lack of both exposure reporting system and knowledge about the ways of reporting. Conclusions: Despite the different established proposals of the post-exposure procedures, it turns out that particularly in small, not providing 24 hours service healthcare settings these procedures are not known or are not respected. More attention should be given to education, especially in regard to the risk of infection, advantages of post-exposure prophylaxis and reporting exposure incidents. Med Pr 2013;64(1):1–10
Wstęp: Wirusowe zapalenie wątroby jest drugą najczęściej stwierdzaną zakaźną chorobą zawodową i rozpoznawaną głównie u pracowników ochrony zdrowia. Ta grupa zawodowa jest najbardziej narażona w miejscu pracy na ryzyko ekspozycji na patogeny krwiopochodne, w tym wirusy HBV i HCV. Celem badania była ocena skuteczności działań ukierunkowanych na bezpieczeństwo pracy w placówkach ochrony zdrowia, częstości incydentów ekspozycji na materiał biologiczny w ostatnich 12 miesiącach poprzedzających badanie oraz ich zgłaszalności. Materiał i metody: Do analizy użyto badania kwestionariuszowego przeprowadzonego w latach 2009-2010 wśród 1138 pracowników ochrony zdrowia. Wyniki: Ekspozycja na materiał biologiczny miała miejsce u 242 pracowników (21% całej grupy). Tylko 146 osób zgłosiło te zdarzenia odpowiednim służbom. Przypadkowe przerwanie ciągłości tkanek miało związek z postrzeganiem pracy jako obarczonej wysokim stopniem narażenia (OR = 3,69, p = 0,0027), zatrudnieniem w ambulatoryjnych (w porównaniu ze stacjonarnymi) placówkach ochrony zdrowia (OR = 1,71, p = 0,0089), przekonaniem o niewystarczającym poziomie przekazywanych przez zakład pracy informacji na temat zakażeń krwiopochodnych oraz brakiem procedur i wiedzy dotyczących raportowania ekspozycji. Wnioski: Mimo prezentowania w różnych publikacjach wytycznych dotyczących postępowania poekspozycyjnego, szczególnie w placówkach nieświadczących usług całodobowych, procedury te są nieznane bądź nieprzestrzegane. Powinien być kładziony większy nacisk na szkolenie pracowników, szczególnie w zakresie ryzyka transmisji zakażeń oraz korzyści płynących z przestrzegania procedur poekspozycyjnych i zgłaszania przypadków ekspozycji.

Opis:: Objectives: Hepatitis B (HBV) and C viruses (HCV) are among the most frequent blood borne pathogens. According to WHO, 5% of healthcare workers (in central Europe), are exposed to at least one sharps injury contaminated with HBV per year, 1,7% - contaminated with HCV. Aims: The aims of the study were to determine prevalence of HCV and HBV infections, vaccination efficacy against hepatitis B and usefulness of alanine aminotransferase (ALT) testing in prophylactic examinations in healthcare workers (HCWs). Material and Methods: In a group of 520 healthcare workers, a survey, laboratory and serologic tests such as ALT, HBsAg, anti-HBs, anti-HBcT and anti-HCV were carried out. Results: The study revealed a low rate of workers with presence of HBsAg and anti-HCV (1,2% and 0,8% respectively). Anti-HBcT was found in 99 subjects (19%) without a significant association with experiencing an occupational percutaneous injury. Being vaccinated against HBV was declared by 90% of the subjects. There was no relationship between ALT level rise and positive HBsAg, anti-HCV and anti-HBcT tests. Conclusion: A seroprevalence of HBV and HCV markers in HCWs found in the study is low and similar to the one found in general population. Current or past hepatitis B infections were independent of needle stick injuries. Vaccination against HBV coverage, although found to be high, should improve to 100%. Occupational prophylactic medical examinations found performing ALT test (obligatory in Poland for HCWs) not helpful. It seems that determination of anti-HBcT and anti-HCV status would be essential in pre-employment medical examinations.

Opis:: Introduction. The aim of the study is the evaluation of the usefulness of High-Speed Digital Imaging (HSDI) in the diagnosis of organic dysphonia in a form of oedematous-hypertrophic changes of vocal fold mucosa, morphologically confirmed by Transmission Electron Microscopy (TEM) method in patients working with voice occupationally. Material and methods. The group consisted of 30 patients working with voice occupationally with oedematous-hypertrophic changes of vocal fold mucosa. Parameters of vocal folds vibrations were evaluated using HSDI technique with a digital HS camera, HRES Endocam Richard Wolf GmbH. The image of vocal folds was recorded with a rate of 4000 frames per second. Postoperative material of the larynx was prepared in a routine way and observed in transmission electron microscope OPTON 900–PC. Results. HSDI technique allows to assess the real vibrations of vocal folds and determine many parameters. The results of TEM in the postoperative material showed destruction of epithelial cells with severe vacuolar degeneration, the enlargement of intercellular spaces and a large number of blood vessels in the stroma, which indicates the presence of oedematous-hypertrophic changes of the larynx. Discussion. The ultrastructural assessment confirm the particular usefulness of HSDI method in the diagnosis of organic dysphonia in a form of oedematous-hypertrophic changes.

Opis:: Introduction: Voice express the psyche and personality of a person. Psychogenic dysphonia is called Phononeurosis. Neurosis, depression or family, occupational and social conflicts are the cause of voice disturbances. The most frequent type of dysphonia is hyperfunctional dysphonia, rarer – hypofunctional type. Aim: The aim of this study is an analysis of voice quality and diagnosis of clinical type of psychogenic dysphonia. Material and methods: The analyzed group consisted of 50 patients with voice disorders treated in 2017 and the control group – 30 people with physiological voice. In the diagnosed group 60% of patients were treated for neurosis, 12% due to depression, the others reported conflict situations. In the diagnosis of clinical type of psychogenic dysphonia GRBAS scale was used, maximum phonation time (MPT) and type of breathing were assessed. The visualisation of the larynx was performed using High Speed Digital Imaging (HSDI) technique. The parametric acoustic evaluation of voice was conducted. Results: The most often clinical type of psychogenic dysphonia was hyperfunctional dysphonia, rarer hypofunctional type and vestibular voice. Dysphonia occurred the most often in women during the highest professional activity period. In the diagnosis of clinical type HSDI technique was especially useful allowing to visualization of the real vocal fold vibration and objective differentiation of hyper- and hypofunctional dysphonia. The acoustic analysis of the voice objectively confirmed the presence non-harmonic components – noise generated in the glottis in hypofunctional dysphonia. Disturbances in the way and breathing type caused irregularities in respiratory-phonic and articulation coordination.

Opis:: Objectives: Wood dust is a known occupational allergen that may induce, in exposed workers, respiratory diseases including asthma and allergic rhinitis. Samba (obeche, Triplochiton scleroxylon) is a tropical tree, which grows in West Africa, therefore, Polish workers are rarely exposed to it. This paper describes a case of occupational asthma caused by samba wood dust. Material and Methods: The patient with suspicion of occupational asthma due to wood dust was examined at the Department of Occupational Diseases and Clinical Toxicology in the Nofer Institute of Occupational Medicine. Clinical evaluation included: analysis of occupational history, skin prick tests (SPT) to common and occupational allergens, determination of serum specific IgE to occupational allergens, serial spirometry measurements, metacholine challenge test and specific inhalation challenge test with samba dust. Results: SPT and specific serum IgE assessment revealed sensitization to common and occupational allergens including samba. Spirometry measurements showed mild obstruction. Metacholine challenge test revealed a high level of bronchial hyperactivity. Specific inhalation challenge test was positive and cellular changes in nasal lavage and induced sputum confirmed allergic reaction to samba. Conclusions: IgE mediated allergy to samba wood dust was confirmed. This case report presents the first documented occupational asthma and rhinitis due to samba wood dust in wooden airplanes model maker in Poland.

Opis:: Long-term exposure to hypercholesterolemia is the cause of atherosclerosis, which in turn causes cardiovascular and cerebrovascular events. In developed countries, including Poland, vascular diseases are the main cause of death. They affect an ever younger part of the population, including the working population. The authors address the problem of epidemiology of cardiovascular diseases, unsatisfactory detection and treatment, economic consequences for the health care system, and the possibilities of using occupational medicine services in the prevention of this health problem. Due to the fact that the early detection of diseases caused by high blood cholesterol levels is relatively low in Poland, obligatory occupational medicine examinations seem to be a key element of the second-line prevention. Therefore, it seems natural to consider the idea of extending the scope of obligatory examinations and introducing tests that allow lipid disorders to be detected at an early stage. This can contribute to a general improvement of the health of the population, and to economic benefits, such as a decrease in the costs of treatment of the disorders that have been detected too late. Broadening the scope of occupational examinations is also important from the perspective of public health and epidemiology of cardiovascular diseases, thus being an element of prevention of civilization diseases. It means improving health and building health awareness, and it should translate into regular health examinations. The performance of these examinations should result not only from the obligation, but also from the patient’s conviction about the importance of early detection of disorders, including lipid disorders, for an effective therapy.

Opis:: Objectives: To evaluate the risk factors for the development of occupational allergy to birds among Polish zoo garden keepers. Methods: A total of 200 bird zookeepers employed in the Polish zoo gardens in Łódź, Warsaw, Gdańsk, Chorzów and Płock and exposed occupationally to bird allergens were examined using a questionnaire, skin prick tests (SPTs) to common allergens and bird allergens, spirometry and cytograms of nasal swab. The level of total IgE in serum and serum-specific IgE to parrot, canary, pigeon feathers and serum were also evaluated. Results: Eight percent of bird zookeepers were sensitized to at least one of the bird allergens. The most frequent allergens yielding positive SPT results were D. farinae — 32 cases (16%), D. pteronyssinus — 30 cases (15%) and grass pollens (16.5%). In the studied group, allergen-specific IgE against bird allergens occurred with the following frequency: 87 (43.5%) against canary feathers and/or serum, 80 (40%) against parrot feathers and/or serum and 82 (41%) against pigeon feathers and/or serum. Occupational allergy was diagnosed in 39 (26.5%) cases, occupational rhinitis was present in 22 (15%) cases, occupational asthma in 20 (13.6%) subjects, occupational conjunctivitis in 18 (12.2%) cases, whereas occupational skin diseases in 11 (7.5%) cases. More eosinophils were found in nose swab cytograms among bird zookeepers with occupational airway allergy. Conclusions: The findings indicate that occupational allergy to birds is an important health problem among zoo bird keepers in Poland.
