Opis:
Objectives Traffic-related particulate matter (PM) is one of the major sources of air pollution in metropolitan areas. This study is to observe the interactive effects of gene and fine particles (particles smaller than 2.5 μm – $\text{PM}_\text{2.5}$) on the respiratory system and explore the mechanisms linking $\text{PM}_\text{2.5}$ and pulmonary injury. Material and Methods The participants include 110 traffic policemen and 101 common populations in Shanghai, China. Continuous 24 h individual-level $\text{PM}_\text{2.5}$ is detected and the pulmonary function, high-sensitivity C-reactive protein (hs-CRP), Clara cell protein 16 (CC16) and the polymorphism in CXCL3, NME7 and C5 genes are determined. The multiple linear regression method is used to analyze the association between $\text{PM}_\text{2.5}$ and health effects. Meanwhile, the interactive effects of gene and $\text{PM}_\text{2.5}$ on lung function are analyzed. Results The individual $\text{PM}_\text{2.5}$ exposure for traffic policemen was higher than that in the common population whereas the forced expiratory volume in 1 s (FEV₁), the ratio of FEV₁ to forced vital capacity (FEV₁/FVC) and lymphocytes are lower. In contrast, the hs-CRP level is higher. In the adjusted analysis, $\text{PM}_\text{2.5}$ exposure was associated with the decrease in lymphocytes and the increase in hs-CRP. The allele frequencies for NME7 and C5 have significant differences between FEV₁/FVC ≤ 70% and FEV₁/FVC > 70% participants. The results didn’t find the interaction effects of gene and $\text{PM}_\text{2.5}$ on FEV₁/FVC in all the 3 genes. Conclusions The results indicated that traffic exposure to high levels of $\text{PM}_\text{2.5}$ was associated with systemic inflammatory response and respiratory injury. Traffic policemen represent a high risk group suffering from the respiratory injury.

Opis:
Introduction and objective. Firefighters are considered a healthy and fit group of individuals, well-prepared for taking action in disaster situations. While working, they suffer from exposure to certain toxic agents, especially combustion products generated when a fire takes place. Among them, the most frequent and the most toxic are: carbon monoxide, hydrogen cyanide, ammonia, and those resulting from PVC combustion – hydrochloride, phosgene and chloride. Additionally, fireextinguisher powder can be inhaled and lead to certain lesion in the airways. The aim of study was to ascertain the influence of toxic agents present at the scene of fire on the lung tissue of firefighters, and also to study this on an animal model. Materials and methods. The study group consisted of firefighters who had a minimum of 10 years service. After completing a questionnaire, their clinical status was ascertained based on a general examination, laboratory tests and lung function tests. Results. Questionnaire analysis showed a high percentage of pathological symptoms in the studied group. The incidence of the symptoms correlated with the duration of occupational exposure to toxic agents. Among other results, obstruction of flow in medium airways in about 30% of the studied individuals represented the most important finding. Experimental tests were next performed on male Wistar rats, aged 3 months. They were insufflated with the solution of powdered fire-extinguisher, after which morphology specimens of lung tissue were studied. Evidence for disseminated fibrosis was obtained, which supported the previous clinical findings in the firefighters. Conclusion. The above shows correlation between occupational exposure and respiratory system involvement in firefighters. This justifies covering the group of firefighters with special medical care focused on prophilaxis, early detection and therapy of pulmonary diseases.

Opis:
W pracy przedstawiono specyfikę rzadko występujących chorób układu oddechowego o nietypowych przyczynach. Omówiono zespół Ardystilu, charakteryzujący się wystąpieniem organizującego się zapalenia płuc, który pojawił się po raz pierwszy u pracowników tekstylnej fabryki sitodruku w wyniku narażenia na inhalację substancji używanych w przemyśle malowania aerograficznego. Opisano wtórną postać proteinozy pęcherzyków płucnych, związaną z narażeniem na czynniki chemiczne i pyły organiczne, a także wystąpienie u robotników rolnych w Portugali i płuca opryskiwaczy winnic. Przedstawiono eozynofilowe zapalenie oskrzeli, wykazujące duże podobieństwo do astmy oskrzelowej, które wystąpiło m.in. u piekarza, pielęgniarki i pracowników narażonych na akrylany, α-amylazę i gazy spawalnicze. Zagrożenie dla układu oddechowego może nieść ze sobą także praca w ekspozycji na diacetyl u pracowników fabryki wytwarzającej popcorn. Nowym czynnikiem, który może powodować choroby oskrzeli i płuc, jest włókno szklane używane przez pracowników budujących małe łodzie i statki. Zwiększone ryzyko wystąpienia dolegliwości ze strony dróg oddechowych występuje też u osób zatrudnionych we włókiennictwie, zawodowo eksponowanych na surowce lub pył bawełny. Czynnikiem ryzyka tych schorzeń są także środki przeznaczone do ochrony różnych powierzchni przed wilgocią. Rzadkie występowanie niektórych zawodowych chorób układu oddechowego powoduje, że niemożliwa jest szczegółowa analiza epidemiologiczna i ocena zależności między czynnikiem etiologicznym a rozwojem schorzenia. W niniejszym przeglądzie piśmiennictwa podkreślono, że wystąpienie choroby układu oddechowego każdorazowo wymaga zwrócenia szczególnej uwagi na narażenie zawodowe i środowiskowe.
This paper reviews rare occupational respiratory diseases with uncommon causes. Among others, it refers to the Ardystil syndrome characterized by the occurrence of organizing pneumonia in the textile printing sprayers, as a result of inhalation of substances used in aerographic textile printing. Furthermore, secondary pulmonary alveolar proteinosis due to exposure to chemical and organic dusts was described, and so was the occurrence of the “vineyard sprayer’s lung” in farm workers in Portugal. Eosinophilic bronchitis, showing a strong resemblance to bronchial asthma, was found to occur, among others, in a baker, a nurse and workers exposed to acrylates, α-amylase or welding gases. Occupational exposure to diacetyl in popcorn production workers might also create a threat to their respiratory system. A newly recognized factor that may cause bronchitis and lung diseases is the fiberglass used by workers building small boats and ships. An increased risk for respiratory ailments is observed in people employed in the textile industry, exposed to commodities or cotton dust. Even the resources used to protect different surfaces against moisture have been recognized as the causative agents of lung diseases. The rare occurrence of some occupational respiratory diseases enables a detailed analysis of the epidemiology and evaluation of the relationship between the etiologic agents and the development of the disease. This literature review highlights the fact that most respiratory diseases require a special analysis of occupational and environmental exposure.

Opis:
Introduction: Most of the pesticides have, by nature, some degree of toxicity because they are intended to kill certain organisms and thus create a risk of damage. The use of pesticides has raised serious concerns, mainly about the potential effects on human health and especially on respiratory system. Thousands of people (from 20,000 to 220,000) lose their life due to pesticide poisoning. Ninety nine percent of them (99%) live in developing countries. Purpose: To review the literature, to identify the harmful effects of pesticides on human health, and particularly on the respiratory system, and to define the ways of dealing with them. Materials and methods: Extensive review of the relevant literature was performed via electronic databases (Medline, Pubmed, Cihnal and Google scholar) and scientific journals (Greek and international) using the appropriate key words: pesticides, respiratory symptoms, pulmonary disease and a combination of them. Results: The effects on human health due to exposure to pesticides depend on a number of factors, including the category of pesticides involved, the amount and type of active substance, as well as their form, route of contamination, exposure time and pesticides' residual dose. Pesticides, especially those that inhibit the action of cholinesterase, lead to the onset of respiratory symptoms. A number of respiratory symptoms and diseases have been associated with occupational pesticide exposures, such as wheezing, asthma cough, phlegm, dyspnoea and influenza like syndrome are reported especially among agricultural workers. Conclusions: Pesticides are dangerous substances for the human body and especially for the respiratory system, if they are used without control. Proper use of pesticides can ensure both the quality of the environment and citizen's safety and health. New scientific data require periodic review of safety levels.

Opis:
The head is an important element of the biokinetic chain. Under physiological conditions, it should extend along the midline of the body. Due to its location and the fact that it constitutes approx. 6% of the total body weight, many authors believe it has a significant impact on its functioning. The aim of this study was to conduct a systematic literature search and to synthesize the evidence of the impact of the head posture on the functioning of the human body. A systematic review was conducted within 3 databases: PubMed, Medline OVID, and EBSCO, using the following terms: “forward head,” “posture,” “position,” and “neck.” For the analysis, scientific articles published after 2013 were selected. A total of 16 studies matched the inclusion criteria of this systematic review. Their results have proven that the position of the head has a significant effect on the human body. Research findings show that abnormal head position changes affect muscle activity, proprioception, the pattern of breathing and neck pain. This is the first systematic review of the relationship between the head posture, and the functioning of the human body. The results of this study seem to be promising if used in therapeutic practice.

This article is a review of research studies conducted in the Central Institute for Labour Protection (CIOP) on ergonomic aspects of personal protective equipment (PPE) design and use. Research was related to, among other things, a comparison of body strain and work time limitation for users wearing gas-tight and drill suits. Some other studies were connected with the biophysical properties of clothing materials for medical use. On the basis of the measurement results, a proposal of clothing construction with an optimum combination of protection and comfort was created. Research leading to the development of test methodology concerning automatic welding filters with switchable luminous transmittance is also conducted n CIOP. The article also brings up the subject of designing new PPE assuring a high level of comfort. A modei of material to be used under tight protective clothing, an inflammable harness for working at a height, and a model of intelligent clothing that will assist human thermoregulation processes during physical effort are examples of new PPE.

This work presents studies on secondary school children inhabiting two regions of Warsaw: Śródmieście (Central part) and Międzylesie (East part). These two locations significantly differ according to air pollution, which is much higher in Śródmieście than in Międzylesie. the sample consist of 219 boys and 225 girls aged 13-16 years. The main aim of this work concerns the evaluation of physical development (body height and weight, BMI and chest circumference, Marty index – chest circ./height) and respiratory parameters (VC, Ziemssen index – VC/height, MV, FEV1 RR, TV, IRV, ERV, Ap) of studied children depending on the place of residence. The data were presented in “z” scores and the difference was calculated using t-test for independent samples. The results show that there were not significant differences in body build as well as in most respiratory functions between children from the Central and East parts of Warsaw. The significant differences were found for IRV and Ap which were greater in children from Śródmieście and for TV and MV which were greater in girls from Międzylesie. The more detailed analysis of these studies, including data concerning living conditions of studied children and smoking habits within their families is under preparation.

Opis:
Na podstawie archiwalnych materiałów źródłowych z 1801 r. przedstawiono przypadek leczenia ostrego schorzenia dróg oddechowych, prawdopodobnie zapalenia płuc, u 72-letniego mężczyzny. W skład zespołu leczącego wchodził doktor, cyrulik, ówczesna „pielęgniarka”, aptekarz, którzy praktykowali w 1801 r. w Koniecpolu. W leczeniu zastosowano leki mukolityczne, przeciwkaszlowe, nasercowe, przeciwgorączkowe, przeciwbólowe, poprawiające apetyt. Leczenie to z współczesnego medycznego punktu widzenia było prawidłowe. Zaordynowano także lekarstwa, które zalecała obowiązująca nadal od starożytności teoria humoralna. Teoria ta zakładała istnienie w ciele człowieka czterech płynów — humorów: krwi, śluzu, żółci, czarnej żółci. Brak proporcji i równowagi między płynami prowadził do choroby. Leczenie miało na celu przywrócenie zaburzonych proporcji i równowagi przez stosowanie leków przeczyszczających, moczopędnych, upustów krwi itp. Z współczesnego medycznego punktu widzenia było to leczenie szkodliwe, gdyż powodowało niedokrwistość, zaburzenia homeostazy wodnej, elektrolitowej i kwasowo-zasadowej. Leczenie zakończyło się zgonem chorego.
According to archival sources from 1801 year treatment of acute respiratory disorder, probably pneumonia in 72 — year old man was presented. The patient was treated by a doctor, barber surgeon, so - called “nurse” and apothecary, who were practicing in 1801 year in Koniecpol. Mucokinetics, anti-cough, cardiac, antipyretic, analgesic and improving appetite medications were used. From the current medical point of view this treatment was correct. Moreover, the medications recommended by still actual from antiquity humoral theory were used. According to that theory the human body was thought to contain four humors: blood, phlegm, bile, black bile. Lack of proportion and balance between humors led to disease. The treatment was designed to restore the proper humoral balance by enemas, diuretics, bloodletting etc. From the current medical point of view the treatment was incorrect. It caused anaemia, disturbances in water, electrolyte and acid — base homeostasis. The treatment resulted in death of patient.

Opis:
This review article presents fundamental mechanisms of the local mucosal immunity in selected regions of the respiratory tract in healthy birds and in some pathological conditions. The respiratory system, whose mucosa come into direct contact with microorganisms contaminating inhaled air, has some associated structures, such as Harderian gland (HG), conjunctive-associated lymphoid tissue (CALT) and paranasal glands (PG), whose participation in local mechanisms of the mucosal immunity has been corroborated by numerous scientific studies. The nasal mucosa, with structured clusters of lymphoid tissue (NALT – nasal-associated lymphoid tissue) is the first to come into contact with microorganisms which contaminate inhaled air. Lymphoid nodules, made up of B cells with frequently developed germinal centres (GC), surrounded by a coat of CD4+ cells, are the major NALT structures in chickens, whereas CD8+ cells are situated in the epithelium and in the lamina propria of the nasal cavity mucosa. Studies into respiratory system infections (e.g. Mycoplasma gallisepticum) have shown the reactivity of the tracheal mucosa to infection, despite a lack of essential lymphoid tissue. Bronchus-associated lymphoid tissue (BALT) takes part in bronchial immune processes and its structure, topography and ability to perform defensive function in birds is largely age-dependent. Mature BALT is covered by a delicate layer of epithelial cells, called follicle-associated epithelium (FAE). Germinal centres (GC), surrounded by CD4+ cells are developed in most mature BALT nodules, while CD8+ lymphocytes are dispersed among lymphoid nodules and in the epithelium, and they are rarely present in GC. Macrophages make up the first line of defence mechanisms through which the host rapidly responds to microorganisms and their products in the respiratory mucosal system. Another very important element are polymorphonuclear cells, with heterophils being the most important of them. Phagocytic cells obtained from lung lavages in birds are referred to as FARM (free avian respiratory macrophages). Their number in chickens and turkeys is estimated to be 20 times lower than that in mice and rats, which indicates a deficit in the first-line of defence in the birds’ respiratory system. There are numerous B cells and antibody secreting cells (ASC) present throughout the respiratory system in birds. Their role comes down to perform antigen-specific protection by producing antibodies (IgM, IgY or IgA class) as a result of contact with pathogenic factors.

Opis:
The comparative study of the acid-base balance (ABB) parameters has been performed on 20 clinically healthy mature Małopolski horses. An arterial blood sample from the facial artery and a sample of venous blood from the external cervical vein were colected from each animal. In the samples tested, the blood pH, pCO₂, tCO₂, HCO₃-, concentration of Na+, K+, Cl-, and a value of the anion gap were determined. The difference among pCO₂, tCO₂, and HCO₃ - in both samples tested was statistically significant, whereas the pH of the arterial blood and the pH of the venous blood did not differ significantly. The anion gap in both types of blood did not differ significantly. Conclusions: 1) ABB parameters such as pCO₂, HCO₃-, and tCO₂ determined in the arterial and venous blood of the Małopolski horses differ from each other significantly. 2) In spite of the lack of the differences between pH of the arterial and venous blood, the ABB parameters in horses should be determined in the arterial blood, because the comparative study performed proves that the analysis of the ABB parameters determined for the venous blood of a healthy horse may lead to a wrong diagnosis of the compensated respiratory acidosis. 3) The mean value of anion gap in horses aged 8-12 years amounts to 20.9 mmol/l for the arterial blood and 19.93 for the venous blood; the difference between the two values is not statistically significant.

Opis:
Choroba Coronavirus Disease 2019 (COVID-19) rozprzestrzeniła się w całym świecie. Atakuje głównie układ oddechowy organizmu, ale powikłania ujawniają się w wielu narządach oraz tkankach. Struktury ochrony zdrowia zostały postawione w stan gotowości do walki z wirusem, którego nie zdążono dobrze poznać. Fizjoterapia post-covidowa skupia się głównie na rehabilitacji układu oddechowego oraz na przeciwdziałaniu skutkom zmian w układzie mięśniowo-szkieletowym. Wśród postępowania fizjoterapeutycznego znalazły się pozycje ułożeniowe, toaleta drzewa oskrzelowego, ćwiczenia czynne oraz fizykoterapia. Ważnym elementem fizjoterapii jest działanie w zespole wraz z lekarzami, pielęgniarkami oraz psychologami. Słowa kluczowe: Covid-19, fizjoterapia post-covidowa, układ oddechowy
Coronavirus disease 2019 (COVID-19) has spread worldwide. It mainly attacks the respiratory system of the body, but complications appear in many organs and tissues. Healthcare teams were put on standby to fight a virus that they did not get to know well. Post-covid physiotherapy focuses mainly on the rehabilitation of the respiratory system and counteracting the effects of changes in the musculoskeletal system. Physiotherapeutic procedures included posture positions, bronchial tree cleansing, active exercises and physical therapy. An important element of physiotherapy is working in a medical team with doctors, nurses and psychologists.

Opis:
Introduction. Bordetella pertussis is a Gram-negative rod which attacks the respiratory system and causes whooping cough disease. Despite the high percentage of childhood vaccination amongst the population an increasing number of pertussis cases have been observed over time, especially among adolescents and young adults. Objective. The aim of the study was to analyze the concentration of IgG anti-PT Bordetella antibodies in the serum of young adults in the aspect of maintaining immunity. Materials and method. The study group consisted of 30 patients, medical students aged 21–26 years. They were interviewed with a questionnaire, which asked about their general health, medications taken, basic information about whooping cough, or vaccination status against B. pertussis. The anti-PT Bordetella levels were measured in the collected serum by a commercial ELISA kit (enzyme-linked immunosorbent assay). Results. All patients had previously received a mandatory vaccination for pertussis as a child, and 36.6%had received a booster dose after the age of 18. The total average antibody level was 13.977 IU/mL (range: <5.00 – 50.74) and 40% of samples had a very low concentration (<5 IU/mL). Conclusions. Current findings suggest that post-vaccine immunity decreases over time, while infection susceptibility among younger age groups who have not yet been fully immunized has increased. Methods that could prevent and enable risk stratification of whooping cough include the screening test for anti-PT Bordetella antibody, the improvement of diagnostics, and an additional booster dose.
