As the natural course of the disease may vary, the treatment should take into account an individual approach to a patient. The appropriate treatment makes it possible to control the symptoms, improves effort tolerance and decreases the risk of exacerbations and death. Tiotropium is a muscarinic receptor antagonist, which is taken once daily, in maintenance therapy, in every stage of the disease progress. The efficacy of tiotropium in regards to exacerbations of chronic obstructive pulmonary disease has been evaluated in many clinical trials against placebo and several different active comparators. This review presents the results of those studies with the main goal to evaluate the efficacy of treatment with tiotropium in terms of prevention and course of exacerbations.

Recent guidelines recommend regular assessment of asthma control and indicate questionnaires as important tools that can facilitate its evaluation. Questionnaires relate to GINA or NAEPP guidelines. Questionnaires constitute complex numerical or categorical scales and consist of several to over a dozen questions relating to the patient's symptoms of asthma, limitations in daily activities and usage of rescue medications within a period of time. Each questionnaire is characterized by the features that affect its reliability and usefulness. In the following paper we discuss most of the questionnaires which assess asthma control. We focus on the items they include and present the results of studies that prove the effectiveness of individual questionnaires in assessment of asthma control. Attention was drawn to the patient groups to which the questionnaires are addressed. We list the features of the questionnaire which should be considered before choosing a test, so that it satisfies both the doctor's and the patient's needs. The role of questionnaires as the easy-to-use tools is growing steadily. Unfortunately, not all are available in Polish language. Conducting appropriate validation studies may allow to use many of them in Polish conditions.

We report a rare case of acute laryngeal dyspnea and rapidly progressive pulmonary changes as first manifestations of disease. A 53 year-old woman presented with symptoms of two-week dyspnea, which aggravated rapidly in the preceding hours. Laryngological examination revealed subglottic infiltrations and vocal fold oedema which required urgent tracheotomy. During few days she developed gingival ulcerations and pulmonary infiltration with negative serum c-ANCA titers. The histopathological examination of subglottic and gingival biopsies and the clinical picture established the diagnosis of GPA. She was treated with prednisone and cyclophosphamide with recovery; however, during over 3 years of follow-up, pulmonary symptoms relapsed and subglottic stenosis persisted. The difficulties in diagnosis and treatment in this unusual presentation of GPA are outlined with conclusion that in patients with subglottic infiltration, which develops rapidly, even when this is a sole presentation of the disease, and when c-ANCA are negative, GPA should always be considered.

We present the case of a 55-year-old woman with synchronous two distinct neuroendocrine lung cancer lesions in the right upper lobe. Initially she showed no signs or symptoms related to lung lesions and was admitted to Thoracic Surgery Ward for the investigation of two oval, solitary pulmonary nodules (11 and 19 mm in diameter) detected on a chest X-ray performed three months earlier. The radiological imaging showed a variability of growth of both lesions (smaller tumor has enlarged while the larger one remained unchanged). After the CT-guided lung biopsy, patient underwent right upper lobectomy. Histological examination revealed a small cell carcinoma in one of the tumors and a large cell neuroendocrine carcinoma in the other one. The patient was discharged in good condition and lung inflation in chest X-ray and qualified for adjuvant chemotherapy with a combination of cisplatin and etoposide and the prophylactic cranial irradiation. Very important issues, having impact on outcome of patients with multiple lung tumours is differentiation whether the lesions are metastases or synchronous primary lung tumors and the optimal management of these patients.

Three distinct histological forms have been identified viz, mucinous, non-mucinous and mixed or indeterminate. The mucinous variety of BAC may present as a consolidation which is very difficult to differentiate from an infective pneumonia. We present a case of a middle aged female who was evaluated for a "non-resolving consolidation" for a period of two years. She had undergone an inconclusive bronchoscopy and had received several courses of antibiotics including anti-tuberculous therapy without relief. The size of the lesion had remained largely unchanged during this period and there was no significant clinical deterioration in the patient. Transbronchial biopsy done on presentation revealed BAC of the mucinous variety. BAC presenting as a large consolidation without significant change for a period of two years has rarely been documented in the literature.

The objective of this study was evaluation of serum high-mobility group box 1 (HMGB1) protein concentration in subjects exposed to fire smoke (SEFS). MATERIAL AND METHODS: The study group consisted of 40 consecutive patients admitted to the Toxicology Unit, Lodz, Poland after exposure to fire smoke. Serum HMGB1 concentrations were measured upon admission to hospital and rechecked on the 2nd and on the day of discharge. Patients also underwent routine toxicological diagnostic procedures applied in case of those exposures, such as carboxyhaemoglobin (COHb) levels and urinary thiocyanate concentrations. The same diagnostic tests were performed in 10 healthy volunteers not exposed to smoke of the control group. RESULTS: The average serum SEFS concentration of HMGB1 protein was not significantly higher on admission in comparison with the respective values recorded on the 2nd day and on the day of discharge. The mean serum level of HMGB1 protein of exposed group was higher than that one in the control group, however the difference was not statistically significant. The highest concentration of HMGB1 protein was noted in serum of 28 subjects exposed to fire smoke reporting at least one symptom and the difference was statistically significant in a comparison with the control group. CONCLUSION: As indicated, an acute exposure to smoke may lead to transient increase of HMGB1 in serum in exposed subjects. Further studies are necessary in order to confirm the importance of this protein in pathogenesis of acute airway injury due to exposure to fire smoke.

In 2005 a single primary care practice, COPD was diagnosed in 183 out of 1,960 eligible subjects ≥ 40 years (9.3%). The aim of this study was to assess mortality rate and causes of deaths in this group after 6 years. MATERIAL AND METHODS: In 2011 we invited all 183 patients with COPD recognised in 2005. We performed spirometry, physical examination, questionnaire of respiratory symptoms, smoking habits, concomitant diseases and treatment. Information about deaths was taken from primary care register, furthermore, family members were asked to deliver medical documentation or death certificate. RESULTS: In 2011 we studied only 74 subjects (40.4%), 43 subjects died (23.5%) and 66 subjects were lost from the follow-up (36.1%). Cardiovascular diseases were the most frequent causes of deaths - 21 subjects (48.8%) (heart attack - 8 patients and stroke - 8 patients). Respiratory failure in the course of COPD exacerbation was the cause of 10 deaths (23.3%). Neoplastic diseases lead to 9 deaths (20.9%) (lung cancer 7 patients). Renal insufficiency was responsible for one death (2.325%), and the causes of 2 deaths remained unknown (4.65%). Subjects who died (predominantly males) were older, had higher MRC score and lower FEV₁. CONCLUSIONS: Study performed six years after COPD diagnosis revealed that 23.5% of subjects died. The main causes of deaths were the following: cardiovascular diseases (mainly heart attack and stroke), COPD exacerbations and lung cancer (more than 75%). Death risk in COPD patients was associated with age, male sex, dyspnoea and severity of the disease.

According to the WHO, they are getting the fourth position amongst the most frequent diseases after cancers, cardiovascular diseases and AIDS. Anaphylaxis is a severe, life-threatening, systemic or generalised immediate hypersensitivity reaction. The analysis of the causes and the clinical picture of anaphylaxis in patients treated at single academic hospital centre was the purpose of the study. MATERIAL AND METHODS: The study was based on retrospective analysis of case records of the patients hospitalised at the Chair and Department of Allergology, Clinical Immunology and Internal Diseases, the Jan Biziel University Hospital in Bydgoszcz in the years 2005-2010. 132 patients, in whom anaphylactic reaction appeared, were analysed. The examined population included 70 men and 62 women at 16-95 years of age. RESULTS: The conducted examinations allowed to obtain information about the causes and the course of anaphylactic reactions. The problem of hypersensitivity to substances of various origin (biological or synthetic) can concern everyone irrespective of sex and age. Nevertheless, the phenomenon of anaphylaxis more often occurred in the examined men than women. Most cases of anaphylactic reactions were reported in the 26-50 age range. Based on the presented results, no regularity was observed in anaphylaxis clinical picture and its causative factor. CONCLUSIONS: It is difficult to forecast the course of the reaction based on the causative factor, for anaphylactic reaction is characterised by a great individual changeability and intensity of the first symptoms.

The epidemiological data indicate that the problem of asthma concerns approximately 4 million people in Poland, whereas almost approximately 70% of them have no diagnosis and are not aware of their illness, and on the other hand in 39% of persons who declared the diagnosis of asthma in a survey the diagnosis was negatively verified (overdiagnosis of asthma). So far, no detailed comparative studies for asthma incidence rate in urban and rural areas were conducted in Poland. The aim of the study was to analyze patients with asthma in Poland in the years 2008-2012, with regard to province and type of commune (rural/urban). MATERIAL AND METHODS: The study used data from National Health Fund (NFZ) - reported by health care providers regarding the patients diagnosed with asthma. Using structured query language (SQL) a set of patients was selected and created, for whom at the same time ICD-10 code: J45.X-bronchial asthma was reported. In order to estimate the number of patients with asthma we used the PESEL social security number as a unique identifier of the patient. Code of the patient's commune of residence in conjunction with the Central Statistical Office data formed the basis for the division of municipalities into urban and rural areas. The analysis of asthma incidence trends in Poland was performed on the basis of health services provided to patients. The analysis was performed by using the Statistica 10 software using a negative binomial regression model. RESULTS: In 2009 a significant increase in the number of patients with asthma was observed compared with the previous year, whereas after 2009 the number of patients diagnosed with asthma remained relatively constant. A significant increase of predominance of women among asthma patients in recent years can be noticed: from 107% in 2008 to almost 115% in 2012 (F:M ratio). Regardless of the analyzed year and the diagnosis the incidence rate remained constant: approximately 55-57% for urban areas and about 43-45% in rural areas. CONCLUSIONS: The average prevalence rate for rural areas is significantly lower than for urban areas. The use of adjusted incidence rate leads to the conclusion that the number of sufferers in urban areas is higher (about 10%) of the number of sufferers in the rural areas. The results of the analysis are consistent with information from previous studies in Poland and in the world.

Occurrence of organizing pneumonia in leukemic patients is most commonly correlated with bone marrow transplant or treatment with antimitotic agents. There have been only four reported cases of organizing pneumonia related solitarily to leukemia or lymphoma. We present a case of 65-year old gentlemen, diagnosed 8 months earlier with B-cell chronic lymphocytic leukemia with no previous hematologic treatment, who presented symptoms of persistent pneumonia with no significant reaction to antibiotics. Chest computed tomography scans showed well-localized consolidation with ground glass opacities and some air bronchogram, suggesting infectious disease. All results of microbiological examinations were negative. Due to radiological progression of parenchymal consolidation despite two intravenous courses of antibiotics open lung biopsy was performed. The histologic examination of lung specimen revealed structures typical for organizing pneumonia pattern. There was no evidence for leukemic involvement in lung tissue, as no sign for infectious factors from histological staining was observed. In the inferior mediastinal lymph node sample progression of chronic lymphatic leukemia to mixed cell lymphoma was diagnosed. Patient was commenced on prednisone 60 mg/daily with fast improvement. We believe that this is the first case of organizing pneumonia as a reaction to the conversion of B-cell chronic lymphocytic leukemia progression to more malignant stage.

However, an ACT does not include assessment of airway inflammation, which is better reflected when measuring nonspecific bronchial hyperresponsiveness (BHR). The authors aimed to find out if the level of asthma control quantified by an ACT correlates with BHR and pulmonary function tests. MATERIAL AND METHODS: 118 asthmatics participated in the study. All patients completed an ACT. The scores of the ACTs were compared with pulmonary function tests and BHR assessed with the methacholine challenge test and expressed as a provocative concentration of methacholine, inducing a 20% decline in the FEV1 (PC20 M in mg/ml). RESULTS: Patients with controlled asthma amounted to 52 (44%) while those with uncontrolled asthma amounted to 66 (56%). In patients with controlled asthma (ACT score ≥ 20) the mean geometric value of PC20M was 2.72 mg/ml (range from 0.25 to > 8.0), whereas 0.94 mg/ml (range from 0.28 to 8.0) (p = 0.02) was observed in patients with uncontrolled asthma (ACT score < 20). Almost 64% (21/33) of uncontrolled asthmatics achieved normal lung function (FEV1 > 80% pred. value) while 19% (5/26) patients with controlled asthma presented an FEV1 < 80% predicted value. Asthma duration in years in controlled asthmatics was significantly shorter than in uncontrolled patients (6.2 ± 8.9 vs. 12.0 ± 11.4, p = 0.005) CONCLUSION: In determining the most accurate level of asthma control it is reasonable to use an ACT in conjunction with BHR, which provides more accurate assessment of bronchial inflammation than ventilatory parameters alone.

MATERIAL AND METHODS: We retrospectively analyzed the documentation of 119 patients, aged 1 to 18 years (mean age: 7.21 ± 4.82), who were seropositive in Toxocara sp. antibodies. In all cases, peripheral blood eosinophils and leukocyte counts, serum total IgE, IgG levels and specific IgG antibodies against excretory and secretory Toxocara sp. antigens were measured at the first presentation. After the confirmation of seropositivity, all children had a routine radiological examination. RESULTS: In the documentation of 23 children (mean age 3.58 ± 2.63 years) we found abnormalities in the radiological examination of their lungs. Fifteen children who had abnormalities in radiological findings presented clinical respiratory complaints such as chronic cough, wheezing, asthma and haemoptysis. Eight children were asymptomatic. The analysis of peripheral eosinophils and leukocyte number, the level of IgE and specific anti-Toxocara IgG presented significantly higher values in children with radiological lesions than in children who had correct radiology. The concentrations of total IgG and gamma globulins were not significantly different. In 10 patients CT showed irregular round nodules with and without halo ranging from 1 to 13 mm. The number of nodules varied from a single lesion to multiple, disseminated ones. All nodules were located in peripheral areas of the lungs. None of them were found in the central areas. In 13 patients, CT images showed ground-glass opacities with ill-defined margins. None of the CT images presented lymphadenopathy and pleural effusion. CONCLUSION: The pulmonary lesions in small children with high eosinophilia and hyperimmunoglobulinemia E could be related to toxocariasis and for this reason they are eligible to undergo therapy with prolonged observation for several months, rather than start invasive malignancy investigations.

Synergistic effect of both mechanisms of bronchodilation can maximize the efficacy of separately administered drugs. The effectiveness of the combination of LABA and LAMA is already confirmed, nevertheless the question about the safety profile of this therapy is still remaining, particularly with regard to the cardiovascular system. The paper discusses the overall safety profile of the combined preparation compare to placebo as well as the active comparators, especially the cardiovascular safety of fixed-dose formulation. Based on the data it has been demonstrated, that the combination of two ultra-long-acting bronchodilators with different complementary mechanisms of action increases the effectiveness of COPD therapy without affecting the safety.

Therefore...Optimal medication should be characterized by good bioavailability, rapid onset of action, a long period of therapeutic activity, with preserved high safety profile and the lowest possible risk of side effects. Therefore, in addition to traditional drug administration routes, such as oral or injection, novel methods for drug applications, for example in the form of a nasal application have been developed. Because of the anatomy of the nose, drugs administered intranasally can be rapidly absorbed and, depending on the nature of the active substance, may act locally on the mucosa or can have a significant systemic effect. Most nasal drugs are developed in the form of solution administered as aerosol. In some cases, these solutions are thixotropic. They are able to change their physical properties under agitation to facilitate supply of the drug and its adhesion to the mucosa. Intranasal corticosteroids represent the mainstay of treatment for any form of chronic allergic rhinitis (AR) and moderate to severe periodic AR, especially with impaired nasal obstruction and frequent occurrence of symptoms. The article discusses the rheological properties of intranasal corticosteroids, their role in therapy and efficacy in the everyday clinical practice.

On physical examination, a loud systolic murmur over the heart was found. Echocardiography revealed narrowing of pulmonary artery with high pressure gradient. Computed tomography of the chest revealed the presence of large tumour localised in the upper anterior mediastinum. Due to the risk of total closure of the pulmonary artery, interventional mediastinotomy was performed and diagnosis of carcinoma embryonale was established. Subsequent chemotherapy (BEP regimen) has brought regression of tumour and significant improvement in haemodynamic parameters (relief of pressure gradient in pulmonary artery). During the second surgery, the resection of all accessible tumour mass together with marginal resection of the right upper lobe was performed. No signs of cardiac or great vessels infiltration was found. Histopathologic examination revealed the necrotic masses and neoplastic foci diagnosed as teratoma immaturum. In a four-month follow-up the patient's condition remained good. The patient is still under the care of both oncological and cardiological specialists. Thus far he has not required further chemotherapy. Holter ECG monitoring revealed no arrhythmia, but the patient is still treated with mexiletine. The patient is planning to return to work.

ABPA rarely presents as lung collapse and such kind of presentation is very rare in non asthmatic patients. We are presenting a series of three cases in which ABPA presented as lobar or total lung collapse. ABPA presenting as opaque hemithorax is a rarity with only a few of them reported in the literature. CASE SERIES: the first case described is a 45-year non-smoker with history suggestive of bronchial asthma and on chest radiological examination was found to have opaque right hemithorax. The second case is of 62-year non-smoker non-asthmatic patient who presented to us as left lung collapse. The last case is of middle lobe collapse in asthmatic male. All cases ultimately were proved to be having ABPA and after treatment showed marked clinical and radiological improvement. CONCLUSIONS: The present case series highlights the need for aggressive approach in diagnosing this treatable condition in cases presenting as segmental or total lung collapse. The condition has a good prognosis if detected early.
