Introduction: Chronic diseases of the respiratory system are serious problem of modern medicine. Constant increase of occurrence of such diseases in the last few decades is particularly disturbing as it has a direct correlation to the rapid increase of costs intended for health care. Asthma is one of the most common chronic diseases of the respiratory system. Purpose: The aim of this thesis was to evaluate chosen pathogenetic and clinical parameters among patients hospitalized because of asthma in the Department of Allergology and Internal Medicine between 2007 and 2009. Materials and methods: The data included in the medical documentation of 544 patients hospitalized because of asthma, was undergone a statistical analysis. Results: The analysis of the medical documentation shows that the presence of such symptoms as whizzing, dyspnea, intensifying of symptoms after exertion or contact with allergens and infections can indicate asthma. Appearance of whizzing, exertion of symptoms after contact with allergens as well as the presence of allergies and asthma in the family are crucial in diagnosing asthma. Additionally, the presence of a cough, shortness of breath and the connection of the symptoms with exertion and infections were characteristic of high sensitivity and moderate chance of a positive prognosis. The measurements of the concentration of nitric oxide in the exhaled air was more specific and sensitive in recognizing asthma in comparison to spirometric tests, eosinophilia and the total concentration of IgE. Conclusion: The results of the research conducted indicate a great demand for specialist care for asthmatic patients which include both diagnostic procedures and intensification of treatment during exacerbations.

Introduction. Breast cancer is the second most prevalent reason for cancer deaths after lung cancer. Incidence rates have increased worldwide. Aim. To present epidemiology of breast cancer in Podkapackie voivodship. Material and methods. This analysis was performed using a systematic literature search. Results. In the Podkarpackie voivodship up until 2014, the incidence rate of female breast cancer was rising and in 2015 it dropped by 68 cases. Even though the survival rate is increasing, it is still one of the leading causes of cancer deaths placing second after lung cancer. Conclusion. Mortality rate, unfortunately, rose gradually. This shows that even though there is a National Health Program aiming at breast cancer awareness and prevention, it is still not enough to reduce the number of breast cancer deaths.

Introduction. Physical activity is known to be an important factor influencing health throughout human life. This issue has become crucial for public health due to the aging of the population in both developed and developing countries. Aim. is to present a literature review on the forms of physical activity undertaken by the elderly, as well as on issues related to physical activity and the population aging. Material and methods. The study was prepared on the basis of a review of Polish and foreign literature. The following databases and data sources were used: EBSCO, ScienceDirect and Google Scholar. An additional source of data were the websites of the Central Statistical Office. Strictly defined key phrases were used during the collection of literature. The work has been divided into thematic subsections on the aging of the society, the impact of physical activity on health and the main topic, i.e. forms of physical activity selected by the elderly. Analysis of the literature. The number of elderly people in Polish society has increased by almost 3.7 million over three decades. Therefore, an important topic is prophylaxis aimed at increasing the number of days in good health, largely covering the broadly understood activation of the elderly. The available data indicate that only 12% of elderly people undertake physical activity once a week. The most common form of spending free time actively is walking (as many as 73% of people in this population declare this form of physical activity in one of the presented studies). Conclusion. Organized forms of physical activity are undertaken much less frequently by the analyzed age group mainly due to financial limitations and limited availability of sports infrastructure

Wstęp. Urazy i wypadki to główna przyczyna hospitalizacji i zgonów dzieci i młodzieży w Polsce. Cel pracy. Opisanie epidemiologii urazów głowy i kończyn u dzieci i młodzieży zgłaszających się do izby przyjęć (IP) o profilu chirurgicznym wybranego szpitala dziecięcego. Materiał i metody. Dokonano analizy retrospektywnej dokumentacji medycznej 3435 pacjentów w wieku 0–18 lat zgłaszających się do IP w latach 2005–2011. Wyselekcjonowano grupę 2245 pacjentów z urazami głowy lub kończyn i dokonano analizy struktury demograficznej pacjentów, określając także okoliczności, miejsce urazu, rodzaj transportu do izby przyjęć oraz postępowanie po urazie (hospitalizacja vs. porada ambulatoryjna). Wyniki. W badanym okresie z powodu urazu głowy zgłosiło się 1216 (35%) pacjentów, z powodu urazu kończyn – 1029 (30%) pacjentów. Większość urazów, zarówno głowy, jak i kończyn, dotyczyła chłopców (61,9% z powodu urazów głowy, 71,2% z powodu urazów kończyn), miała miejsce w II i III kwartale roku (odpowiednio: 36,1 i 43,1%), najczęściej dzieci w wieku 10–14 lat i powyżej 14 lat (odpowiednio: 28 i 24,4%). Większość dzieci z urazami głowy lub kończyn zgłaszała się do lekarza w ciągu 24 godzin od urazu (odpowiednio: 97 i 91% pacjentów). Większość pacjentów (74,6%) nie wymagała hospitalizacji. Wnioski. Urazy głowy i kończyn stanowią główną przyczynę zgłaszania się dzieci w trybie pilnym do izby przyjęć. Konieczne jest wdrożenie i propagowanie akcji edukacyjnych adresowanych do rodziców, nauczycieli, dzieci, młodzieży, mających na celu zwiększenie zasad profilaktyki urazów i wypadków u dzieci i młodzieży. Wskazane jest większe zaangażowanie pracowników medycznych w promowanie zasad profilaktyki wypadków i urazów u dzieci i młodzieży.

Background. Injuries and accidents are the main cause of hospitalization and deaths of children and youth in Poland. Objectives. The aim of this study was to describe the pidemiology of head and leg injuries in children and adolescents admitted to the emergency department (IP) profile of the selected children’s hospital surgery. Material and methods. A retrospective analysis of 3435 medical records of patients aged 0–18 years admitted to the IP in 2005–2011. Selected group of 2245 patients with head and limb injury and an analysis of patient demographics, determining the circumstances of the place of injury, type of transport to the emergency department and the treatment after the injury (vs. tip-patient hospitalization). Results. In the analyzed period due to a head injury 1216 (35%) patients were admitted and with limb trauma – 1029 (30%) patients. Most of the injuries, both head and limbs involved males (61.9% as a result of head injuries, 71.2% of the injuries of the limbs), took place in the second and third quarters of the year (respectively 36.1% and 43.1%), most often children age was 10–14 years and above 14 years (28% and 24.4%). Most children with head or limb injury reported to the doctor within 24 hours of injury (97% and 91% respectively). Most patients (74.6%) did not require hospitalization. Conclusions. Injuries of head and limbs are the leading cause of children reporting to the emergency room for surgery. It is necessary to implement and promote educational campaigns targeted at parents, teachers, children, youth, aimed at increasing the principles of prevention of injuries and accidents of children and adolescents. A greater involvement of health professionals in promoting the principles of prevention of accidents and injuries of children and adolescents is recommended

The essay describes the Polish episode in the 1918–20 influenza pandemic, situating the occurrence in the European and international context, and covering some relevant research issues. The topic is introduced by a brief discussion of the most recent hypotheses regarding the genesis of the pandemic and how it related to the World War in its declining phase. The core section, discussing the situation in Poland, begins with a description of the civilisation crisis caused by the frontline recurring across the country and the policies pursued by the occupational powers and the tough sanitary conditions implied by these developments. A survey of accessible sources is preceded by an outlined reconstruction of the course of the epidemic in various areas of the country, delineation of its timeframe, description of the symptoms and of the responses to the disease, attempts made to prevent its dissemination, and treatment methods in use at the time. The author seeks to determine the basic figures such as the morbidity and mortality rates, as compared against the data available for the other countries. In conclusion, considered are the presumed reasons behind the disappearance of the ‘Spanish flu’ epidemic experience from Polish collective memory.

This study outlines an analysis of selected anthropo-demographic data ofDer Bielitzer Zionpopulation from parish registers and historical sources. The analysis focuses on three epidemics: cholera (two) and typhoid fever (one) which took place in mid-19th century in Bielitz. The aim of this paper is to explore the demographic structure of the fatalities due to the epidemics and to propose possible causes of any variations. Analysis shows the divergence in the age structure of deceased parishioners between the normal and epidemic years. Also, similar outbreaks of infection but of different pathogenesis could lead to observable discrepancies in the overall demographics of the deceased. In the case of cholera: more fatal cases were seen in the city, a higher frequency of deaths occurred in Bielitz females, the disease occurred only in the warm months and the outbreaks were of short duration. For typhoid fever: more fatal cases were seen in the peri-urban villages, a higher frequency of deaths occurred in the female of the peri-urban villages and the outbreak was of long duration. Frequencies and mortality rates of the above causes of death were compared with younger, more advanced populations. The similarities between these groups suggest a high socio-economical status ofBielitzer Zion.

Bielski Syjonstanowił grupę luteran wyznania ewangelicko-augsburskiego, żyjącą w dziewiętnastowiecznym Bielitz, Bielsku (dzisiaj: Bielsko-Biała), jak również był dzielnicą miasta zamieszkiwaną głównie przez protestantów (Fig. 1). Celem artykułu było przybliżenie wybranych informacji o stanie bio-demograficznym wspomnianej populacji w kontekście analizy danych metrykalnych parafii oraz zródeł historycznych. Zagadnienie badawcze stanowią trzy epidemie: dwie cholery oraz jedna duru brzusznego, które miały miejsce w połowie XIX wieku. Analizie poddano strukturę demograficzną populacji zmarłych, przyczyny zgonów (Tab. 2, 3) oraz zróżnicowanie pomiędzy przypadkami cholery i duru brzusznego w aspekcie różnych zmiennych (płeć, wiek, pochodzenie: miasto lub okoliczne wioski; Tab. 2, 4), a następnie zaproponowano możliwe przyczyny obserwowanych różnic.Praca obrazuje dostrzegalną zmienność pomiędzy strukturą wieku zmarłych parafian w latach normalnych i epidemicznych (Fig. 5). Dodatkowo, zwraca uwagę na obserwowalne różnice w strukturze demograficznej zmarłych w wyniku dwóch rodzajów epidemii (Tab. 4), takie jak wyższa częstość przypadków cholery w mieście (Fig. 3-4; Tab. 1), wyższa częstość zgonów wśród mieszczanek (Tab. 2), krótkie okresy trwania wspomnianych katastrof, czy występowanie ich podczas miesięcy letnich (Fig. 3-4). W przypadku epidemii duru brzusznego obserwowano wyższą częstość zgonów w otaczających Bielsko wioskach, w szczególności wśród kobiet (Fig. 2; Tab. 1), czy długi okres trwania katastrofy (Fig. 2). Uzyskane w wyniku analizy wybrane częstości przyczyn zgonów oraz wskazniki śmiertelności (dla cholery, duru brzusznego, chorób infekcyjnych, gruzlicy) porównano z danymi dla innych, dziewiętnastowiecznych populacji. Grupa bielskich protestantów w połowie XIX wieku mogła charakteryzować się stosunkowo wysokim statusem społecznym, jako że uzyskane wartości odpowiadają charakterystycznym dla populacji z ostatniej dekady dziewiętnastego stulecia.

Objectives About 5–10% of asthmatics do not respond well to standard treatment plan. Occupational exposure may be one of the factors that can be linked with treatment failure. The aim of the study was to assess the prevalence of work-related asthma (WRA) among adult asthmatics under follow up in an outpatient allergy clinic and to create a useful tool for detecting individuals with possible WRA. Material and Methods Preliminary 5-question questionnaire designed to recognize WRA was presented to 300 asthmatics. All patients with positive preliminary verification along with 50 subjects from control group were asked to fill up a detailed questionnaire. The WRA was diagnosed by positive match for asthma symptoms in combination with workplace exposure indicated in the detailed WRA questionnaire followed by confirmation of each WRA case by detailed exposure analysis. Results Work-related asthma was recognized in 63 subjects (21% of study group). The preliminary questionnaire has 76.9% sensitivity and 94% specificity in recognition of WRA. Occupational exposure to irritants is a risk factor of WRA recognition (relative risk (RR) = 2.09 (1.44:3.03)). Working in exposure-free environment is a factor against WRA recognition (RR = 0.38 (0.24:0.61)). Among subjects with work-related asthma, the uncontrolled course of the disease is significantly more frequent (p = 0.012). Subjects with WRA more often report sickness absenteeism due to asthma than those without WRA (9.6% vs. 3.2%, respectively), but the observed differences did not reach the statistical significance. Conclusions Short 5-question questionnaire seems to be a promising tool to detect individuals with possible work-related asthma in the outpatient setting for further evaluation and additional attention.

Aim. The aim of the study was to review the literature on the prevalence of cervical spine injuries divided between the level of the injury and the causes of fractures. Material and methods. A review of Polish and foreign literature was performed. The following databases were searched: PubMed, Medline, Science Direct, Termedia, and Polish Medical Bibliography. Literature analysis. In Poland the incidence of spinal injuries, including damage to the cord, is estimated at the level of 25–35 persons per one million of the population, half of these being cervical spine injuries. More than one in three of all spinal injuries affect the atlantoaxial and occipital area. It is estimated that axis fractures occur in up to 40% of the cases involving cervical spine injury. Odontoid fractures constitute 10–15% of all cervical spine fractures. Hangman fractures account for 20% of vertebral fractures. Cervical spine injuries more frequently occur in males than in females, and the relevant rates for males are from 1.5 to 2.7 times higher. The most common causes of cervical spine injuries include road traffic accidents, accounting for 33 to 75% of the cases, falls from heights (15–44%) and sports injuries (4–18%). Cervical spine injuries are most often diagnosed in subjects over thirty years of age. Such injuries most commonly are related to the second, fifth and sixth cervical vertebrae. On the other hand damage to the first and second cervical vertebrae is often observed in the same patients who are found with injury to lower cervical vertebrae (approx. 9% of the cases). In the group of advanced age subjects the most frequent cervical spine injuries are axial fractures and they are diagnosed in 15% of adult patients with cervical spine fractures.

The increasing prevalence of acquired carbapenemases in Gram – negative bacteria is one of the biggest problems in the prevention and therapy of infectious diseases. NDM (New Delhi Metallo--Lactamase) is a recently discovered enzyme which has the ability to hydrolyze all -lactam antibiotics, except aztreonam. Making that scenario more worrisome is the fact that mobile fragments of DNA carrying blaNDM genes, also keeps a number of other genes encoding antibiotic resistance. NDM enzymes are currently present in different species of bacteria all over the world. NDM-producing bacteria are resistant to virtually all available antimicrobial agents except tigecycline, colistine and fosfomycine

Laryngeal cancer is the most common cancer of the head and neck. The main predisposing factor is exposure to cigarette smoke, alcohol, occupational factors and HPV infections. An analysis of the incidence of laryngeal cancer in Poland shows that since the beginning of the 1990s the incidence in females has been increasing, while in Podkarpackie Voivodship there is very slight increase. The aim of the work is to explore model-based assessment of dynamics of cancer incidence and to analyze the causes of changes in the incidence of laryngeal cancer in females in Podkarpackie Voivodship in the years 1990–2012, including lifestyle, socio-economic situation, and making comparisons with the incidence trends in the country as a whole. For this purpose, a retrospective analysis of cases of laryngeal cancer in Podkarpackie Voivodship in the years 1990–2012 has been performed. Data have been obtained from the publication of the Department of Epidemiology of Podkarpackie Center of Oncology in Rzeszow and the Centre of the Maria Skłodowska-Curie Institute of Oncology in Warsaw. Dynamics of cancer incidences derived from raw data is misleading. Therefore, to analyze the dynamics of the phenomenon three regression models have been used to remove random disturbance: ARX(1), SVR and Poisson regression model. The models have been compared based on standard statistics. In Podkarpackie the model-based absolute number of cases per year in females increased slightly between 1990–2012. In Poland, the model-based absolute number of cases in females increased over 30% in the last two decades in the years 1990–2012. The percentage share of cases of laryngeal cancer in females among all malignant cancers decreased by 0,5% to 0,4% in the years 1990–2012. The average age of the incidence for females increased from 55,6 years in 1989 to 65,4 in 2010. Dynamics analysis based on raw data solely may produce misleading results in opposition to a model based approach. A model-based approach seems to be relevant especially for the ill-behaved time series for such a number of cancer incidences.

Rak krtani jest najczęściej występującym nowotworem regionu głowy i szyi. Podstawowym czynnikiem predysponującym jest ekspozycja na dym tytoniowy, alkohol, czynniki zawodowe. Analiza zachorowalności na raka krtani w Polsce wykazuje, że od początku lat 90. dynamika zachorowalności u kobiet wykazuje tendencję rosnącą podczas gdy w województwie podkarpackim widoczny jest zaledwie słaby wzrost. Celem pracy jest zastosowanie modeli regresji do oceny dynamiki zachorowań oraz analiza przyczyn zmian w zachorowalności na raka krtani u kobiet w latach 1990–2012 na obszarze województwa podkarpackiego z uwzględnieniem stylu życia, sytuacji społeczno-gospodarczej oraz odniesienie ich do trendów w zachorowalności na obszarze kraju. W tym celu dokonano retrospektywnej analizy zachorowań na raka krtani w latach 1990–2012 dla województwa podkarpackiego. Dane dotyczące zachorowań uzyskano z publikacji Zakładu Epidemiologii Podkarpackiego Centrum Onkologii w Rzeszowie oraz Centrum Onkologii Instytutu Marii Curie-Skłodowskiej w Warszawie. Dynamika zachorowań wyznaczona tylko na podstawie surowych danych może być bardzo myląca. Dlatego do badania dynamiki zjawiska zastosowano trzy modele regresji: ARX(1), SVR i regresję Poissona. Modele zostały porównane w oparciu o standardowe statystyki. W województwie podkarpackim bezwzględna liczba zachorowań w skali roku u kobiet w latach 1990–2012 wyznaczona z modelu wzrosła nieznacznie. W Polsce liczba bezwzględna zachorowań u kobiet wyznaczona z modelu wzrosła w tym czasie ponad 30%. Odsetkowy udział zachorowań na raka krtani u kobiet wśród wszystkich nowotworów złośliwych w Polsce w latach 1990–2012 zmniejszył się z 0,5% do 0,4%. Średnia wieku zachorowań dla kobiet w regionie Polski południowo-wschodniej wzrosła z 55,6 lat w 1989 do 65,4 w 2010 roku. Przeprowadzone badania skłaniają do wnioski, że ocena dynamiki zjawiska tylko w oparciu o surowe dane może prowadzić do sprzecznych wniosków w przeciwieństwie do podejścia opartego o model. Zastosowanie modelu regresji jest uzasadnione w szczególności dla szeregów czasowych o dużej zmienności takich jak zachorowania na raka.

Objectives: The epidemiology of acute poisonings, observed in Toxicology Unit in Łódź, is the main objective of the study. The authors present frequency of respective kinds of poisoning cases and associated mortality. They discuss also the structure of poisonings with regard to type and causative agents over a period between 2003 and 2007. Materials and methods: The data used for the analysis were obtained from National Poison Information Center in Łódź. They were divided into two groups. The first one comprised information about patients treated at the Toxicology Unit (TU), whereas the other one included cases treated in other hospitals and only consulted by TU staff. Results: Analysis of the data shows that overdosage of medications was the most frequent cause of hospitalization during 2006-2007. It constituted also the leading cause of deaths due to poisoning during 2003-2005. However, it was superseded during the subsequent period of 2006-2007 by intoxication with alcohols which was associated with the highest number of deaths in the latter period. Situation changed dynamically also with regard to the intention of poisoning. Suicidal poisonings constituted the largest group in 2003, whereas poisonings caused by abuse, including dependence-related abuse, were the most frequent in subsequent years. Patients between 15 and 30 years old formed the largest group among the total number of poisonings. Conclusions: The results of our study on epidemiology of acute poisoning in Łódź between 2003-2007 show that poisoning is a frequent cause of admission to hospital and constitutes a major health problem in Łódź district because of large number of hospital admissions, associated mortality and the high proportion of patients at young age.

maintaining sleep and/or waking up too early. As a result, patients may complain about physical and mental fatigue and general malaise during the day. Hence, people suffering from insomnia often look for treatment options. Objectives. To assess the frequency of insomnia in seniors; to establish the main predisposing factors and to evaluate the pharmacotherapy. Material and methods. The study was conducted in the group of 298 aged 60+ residents of Lodz region, Poland. An anonymous questionnaire concerning lifestyle, sleep disorders, and hypnotics use was conducted by each patient. The Athens Insomnia Scale – a standardized questionnaire to diagnose insomnia was also performed. Patients were allocated into 2 groups: with and without insomnia. Collected data were statistically analyzed with the use of the t-student and chi-square tests. Results. 25.8% of all patients were diagnosed with insomnia, and greater age, female sex, and mental or neurological disorders were found to be associated with insomnia in the elderly. Moreover, 22.8% of all patients took hypnotics despite the fact that 41.2% of them did not fulfill the criteria of insomnia. H1-blockers (32.4%) were the most often used. Conclusions. While H1-blockers are not recommended as the first choice insomnia drugs, they are the most frequently used hypnotics. A significant group of patients take these without medical recommendation. The implementation of a simple tool for diagnosing insomnia in everyday practice would be useful.

Celem pracy była analiza zmian w zachorowaniach na nowotwory odbytnicy w latach 1990–2005, sformułowania wniosków oraz odniesienie ich do analogicznych danych dla Polski oraz innych krajów Europy. Materiał i metody: Analizie poddano 2573 zachorowania na raka odbytnicy. Metodą retrospektywnej analizy oceniano zachorowalność na nowotwory odbytnicy na Podkarpaciu opracowano współczynniki zachorowalności surowe i standaryzowane oraz wskaźniki struktury zachorowań. Wyniki: W latach 1990 – 2005 zarejestrowano 1464 zachorowania na raka odbytnicy u mężczyzn i 1109 u kobiet – razem 2573. W 1990 r. zachorowania u mężczyzn stanowiły 29,5% wszystkich zachorowań na nowotwory odbytnicy, a u kobiet 70,5%. Współczynnik mężczyźni /kobiety wynosił 0,66. W roku 1990 nowotwory odbytnicy stanowiły 0,83% wszystkich nowotworów u mężczyzn na Podkarpaciu i 1,5% u kobiet. W 2005 r. zachorowania u mężczyzn stanowiły 60,5% zachorowań na nowotwory odbytnicy, a u kobiet 39,5%. Współczynnik mężczyźni/kobiety wynosił 1,53. Wnioski: W latach 1990–2005 zachorowania na nowotwory odbytnicy wzrosły 5-krotnie oraz zwiększyły swój odsetek w ogólnej liczbie nowotworów 6-krotnie u mężczyzn i 3-krotnie u kobiet. W liczbie tej 66,9% chorych stanowili mężczyźni, a 33,1% kobiety. Współczynnik surowy zachorowań dla mężczyzn wzrósł w tym okresie 8-krotnie, a u kobiet 3,5-krotnie. Współczynniki standaryzowane wzrosły u mężczyzn ponad 6-krotnie, a u kobiet prawie 2-krotnie.

Introduction and the aim of the study: Between 1990 and 2005, the number of incidence cases of the malignant neoplasm of the alimentary tract in Podkarpacie region rose from 727 to 1154 and it led to a 63% increase. The aim of the study was to analyse incidence rates for rectal neoplasm within the Podkarpacie area between 1990 and 2005, to make conclusions and confront them with the corresponding data for Poland and other European countries. Research material and methods: Incidence cases for rectum carcinoma were assessed by the retrospective analysis of material covering 2573 reports. The standardized and crude incidence ratios were formulated and incidence percentage rates were determined, as well. Results: The registered rectum carcinoma in the period under study totaled 2753 incidence cases, out of which 1464 in men and 1109 in women. In 1990, the number of rectal cancer incidence cases for men was 29,5% of all rectal cancers, and for women was 70,5%. The proportion of rectal cancer incidence cases for men and women was 0,66. In 1990, rectal cancers constituted 0,83% of all carcinomas in men and 1,5% in women in Podkarpacie region. In 2005, morbidity in men was 60,5% of all rectal cancers and 39,5% in women. The proportion of rectal cancer incidence cases for men and women was 1,53. Conclusions: Between 1990 and 2005, rectum cancer morbidity generally increased fivefold which led to the rise of all neoplasms sixfold in men and threefold in women. The neoplasm of the rectum constituted 66,9% in men and 33,1% in women. The crude incidence ratio increased eightfold in men and 3.5-fold in women. The standardized incidence ratio rose more than six times in men and about two times in women.

Though much evidence indicates that work stress increases the risk of incident of coronary heart disease (CHD), little is known about the role of work stress in the development of recurrent CHD events. The objective of this study was to review and synthesize the existing epidemiological evidence on whether work stress increases the risk of recurrent CHD events in patients with the first CHD. A systematic literature search in the PubMed database (January 1990 – December 2013) for prospective studies was performed. Inclusion criteria included: peer-reviewed English papers with original data, studies with substantial follow-up (> 3 years), end points defined as cardiac death or nonfatal myocardial infarction, as well as work stress assessed with reliable and valid instruments. Meta-analysis using random-effects modeling was conducted in order to synthesize the observed effects across the studies. Five papers derived from 4 prospective studies conducted in Sweden and Canada were included in this systematic review. The measurement of work stress was based on the Demand- Control model (4 papers) or the Effort-Reward Imbalance model (1 paper). According to the estimation by meta-analysis based on 4 papers, a significant effect of work stress on the risk of recurrent CHD events (hazard ratio: 1.65, 95% confidence interval: 1.23–2.22) was observed. Our findings suggest that, in patients with the first CHD, work stress is associated with an increased relative risk of recurrent CHD events by 65%. Due to the limited literature, more well-designed prospective research is needed to examine this association, in particular, from other than western regions of the world.

Przemieszczanie się ludności między kontynentami jest coraz częstsze, szybsze i łatwiejsze. W ostatnich latach popularnym celem wypraw turystów są głównie kraje strefy tropikalnej. Bardzo gorący klimat oraz nie najlepszy stan sanitarno-higieniczny powodują ogromne zagrożenie nabycia wielu chorób, które są charakterystyczne dla rejonów egzotycznych. Malaria obecnie jest na trzecim miejscu wśród najważniejszych chorób zakaźnych na świecie, zaraz po AIDS i gruźlicy. Te choroby łącznie powodują więcej niż połowę wszystkich zgonów na całym świecie z powodu chorób infekcyjnych. Malaria jest najczęstszą chorobą człowieka w skali globu. Uważa się, że 40–45% populacji, w tym aż 40% dzieci, żyje na obszarach endemicznych malarii. Trudno o dokładne dane statystyczne pokazujące zachorowalność w Polsce na choroby tropikalne. Pierwszorzędowym zarażeniem pasożytniczym o globalnym znaczeniu jest malaria. Liczba przeniesionych z terenów malarycznych do Europy przypadków przekracza rocznie 10 000, a wywołana nimi śmiertelność stanowi kilka procent. W pracy przedstawiono kierunki rozprzestrzeniania się tej choroby na świecie z uwzględnieniem jej występowania na terytorium Polski.

Population movements between continents is becoming more frequent, faster and easier. In recent years, tropical countries are the most popular travel destination. Very hot climate, poor sanitary-hygienic state cause a huge threat of acquire many diseases that are characteristic of the exotic regions. Malaria is now in third place among the most important infectious diseases in the world, after AIDS and tuberculosis. In total, they cause more than half of all deaths worldwide caused by infectious diseases. Malaria is the most common human disease in the global scale. It is believed that 40–45% of the population, including 40% of children living in malaria endemic areas. It is difficult to obtain accurate statistics on the incidence of tropical diseases Poland. The primary parasitic infection of global importance is malaria. Total transferred cases from malarial areas to Europe exceed 10 000 and mortality mortality is a few percent. The paper presents trends in the spread of the disease in the world with regard to its presence on Polish territory.

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.

Introduction: Studies based on the ISAAC questionnaire suggest a correlation between the use of antibiotics and the prevalence of asthma and allergy in children aged 6-7 years. The number of courses of antibiotic therapy is an important factor. Objectives: To investigate the relationship between the use of antibiotics during the fi rst years of life and the prevalence of allergy and asthma among children (aged 6-8 years) in the urban population of Poland. Materials and Methods: A survey-based study with a self-completed questionnaire. The respondents were parents of children aged 6-8 years living in Warszawa, Poland. 1461 completed questionnaires were collected. Results: Asthma was declared in 4.3% of the children. Wheezing and/or sibilant rhonchi within 12 months before the study was observed in 13.5% of the cases. Asthma medication was taken by 21.8% of the children. Allergic rhinitis was declared in 18.7% of the children. Problems with sneezing, rhinorrhea, and nasal congestion not associated with cold or fever were observed in 40.7% of the children. The a nalysis of the odds ratios between the use of antibiotics and the symptoms of allergic diseases revealed a clear correlation. The highest odds ratio was observed between the completion of over three courses of antibiotic therapy prior to the age of 12 months and the declaration of one of the following: asthma (OR = 5.59, 95% CI: 2.6-12.01), wheezing and/or sibilant rhonchi (OR = 4.68, 95% CI: 3.01-7.27) and taking medicines for breathlessness (OR = 5.12, 95% CI: 3.42-7.68). Conclusions: There is a direct relationship between antibiotic use in the fi rst 3 years of life and asthma and allergy symptoms in children aged 6-8 years old.

Introduction and aim. With the third wave of COVID-19 hitting the country, there is an urgent need to systematically document the clinical-epidemiological and vaccination details of the patients to formulate evidence-based decisions. So, this study was planned to describe the profile of patients attending the flu clinic of a tertiary care hospital in eastern India. Material and methods. This hospital-based cross-sectional study was done for 6 weeks (Jan-Feb 2022) among 623 patients using a pre-tested, structured questionnaire related to COVID-19. An unadjusted odds ratio was calculated and statistical significance was attributed to a p-value <0.05. Results. Out of 623 patients, almost 90% of the patients were vaccinated against COVID-19 with at least one dose of any vaccine. Cough (57.8%) was the most common complaint. Patients aged > 60 years and those having one or more than one comorbidity suffered from moderate-severe COVID-19 infection when compared to their counterparts (p<0.001). Also, 2.1% of fully vaccinated, 3.8% of one dose vaccinated and 10.9% of unvaccinated patients suffered from moderate-severe COVID-19. Conclusion. During the third wave of the COVID-19 pandemic, a smaller number of elderlies compared to the previous two waves were affected indicating age shifting. The severity of COVID-19 was less among vaccinated individuals compared to unvaccinated highlighting the importance of COVID-19 vaccination.

Since one of the main mode of the COVID-19 transmission is through close contact with the infected person (<1.5 m distance) and body fluids (saliva, blood, aerosol particles), the dentists have become one of the groups being at most risk of being infected. The aim of this article is to present, based on the research search (publications from the last year 2020 and from the beginning of the current year 2021), the general overview of the situation during the COVID-19 pandemic with regard to patients and dentist as well as supporting personal protection. Authors identified 7 questions related to this topic. They address among others such issues as identification of the COVID-19 patients coming to the dental practice; protection of both the dentist and the patient from infection and a need for guidelines on the scope of emergency dental services during the pandemic. Opinions on the subject, expressed by the experts in the field, including general guidelines were also taken into consideration. In general, based on the literature overview, the COVID-19 pandemic has completely transformed the healthcare system, including dentistry. The identification of the COVID-19 patients coming to the dental practice has become a necessity (including taking epidemiological survey, temperature measurement). Currently, since “the group zero” in significant part has completed the full vaccination process, the health personnel (including dentists) might feel safer. The efficacy of the vaccines is high and provides a certain sense of security.
