Rituximab was introduced resulting in B-cell depletion and disappearance of anti-PR3 antibody. Palatal holes have substantially diminished and all bronchial perforations disappeared, covered by fibrous tissue. In the fourth month after rituximab administration, large scarring obstruction of the right main bronchus with upper and middle lobes atelectasis emerged. Because of increasing dyspnoea, stenotic bronchus was re-opened by bronchoscopy. Intervention was complicated by bilateral pneumothorax and later, on the seventh day, by fatal pulmonary bleeding. To our knowledge, this is the first report of GPA refractory to cyclophosphamide complicated by palatal and bronchial perforations.

Since 1939, only 22 patients (10 with immediate type I reactions and 12 with delayed) have been documented with allergy to mango. History of atopy and geographical region may influence the type of reaction. Immediate reactions occurred most often in patients with history of atopy, while delayed reactions developed in non-atopic individuals. Clustering of delayed hypersensitivity reports from Australia and immediate reactions from Europe has been documented. We report a 50-year-old man with immediate type I hypersensitivity to mango, who developed cough, wheezing dyspnoea, generalised itching and abdominal discomfort after ingestion of mango. Life threatening event can also happen making it imperative to diagnose on time, so as to prevent significant morbidity and potential mortality.

Some studies of the prevalence of latent tuberculosis infection (LTBI) have already been performed in Poland, showing that almost a quarter of the Mazovia population could be infected. It also indicated a higher prevalence of LTBI among seniors. Those studies were based on indirect diagnostic methods. MATERIAL AND METHODS: We randomly collected hilar lymph nodes from decedents aged 40 years and older during post-mortem examination. We excluded patients with previous confirmed tuberculosis. In addition, an autopsy was performed in all patients. Finally, we used real-time PCR Xpert MTB/RIF (Cepheid, USA) for the specific capture of mycobacterial DNA. RESULTS: Twenty-two of 23 patients had a negative result of the real-time PCR examination and no signs of caseous necrosis in hilar lymph nodes. We found the only positive sample in a patient with histopathological signs of tuberculosis (the presence of caseous necrosis in the specimens obtained from lymph nodes and lung). Due to the change of cartridges from version G3 to G4, further reactions were inhibited and no more post-mortem samples were tested. CONCLUSIONS: Real-time PCR Xpert MTB/RIF was capable of detecting M. tuberculosis complex DNA in a patient with tuberculosis recognised on autopsy. In the remaining patients, no M. tuberculosis complex DNA was found, in accordance with negative results of histological examination. Since the technology of cartridges has changed, it is no longer possible to use real-time PCR Xpert MTB/RIF (Cepheid USA) on post-mortem material.

MATERIAL AND METHODS: 50 NSCLC patients (25 adenocarcinoma, 21 squamous cell and 4 adenosquamous), clinical stages I and II, age 42-89 years, entered the study. CEA, Cyfra 21-1 and CRP concentrations were measured in serum taken before surgery, CEA and Cyfra 21-1 in 50 patients, CRP - in 46 patients. The survival was calculated from the date of surgical treatment until death or until the end of the observation time. The results were expressed as medians (95%CI). RESULTS: Cyfra 21-1 concentration was 2.1 (0.7-14.5) ng/mL. Survival time in the patients with Cyfra 21-1 ≤ 2 ng/mL, and > 2 ng/ /mL was 79 (14.85-88.2) and 29 (5.7-87.6) months, (p < 0.026). CEA concentration was 2.68 (0.87-72.7) ng/mL, significantly higher in adenocarcinoma than in squamous cell lung cancer - 4.38 ng/mL (1.67-41.35) vs. 2.2 ng/mL (1.0-6.1), p = 0.002. CRP concentration was 5.45 (0-122.6) mg/L. Significant dependence was found between CRP and pathological tumour size (pT). Median CRP values in pT1, pT2 and pT3+4 tumours were: 2.8 mg/L, 6.9 mg/L and 23.5 mg/L, respectively. Survival time of the patients with CRP ≤ 10 mg/L and CRP > 10 mg/L was 79 (14.85-88.2) and 29.5 (5.7-87.6) months, respectively (p = 0.045). CRP > 10 mg/L and Cyfra 21-1 > 2 ng/mL were the only significant preoperative prognostic indicators (HR 2.08 and 2.04, respectively). Among the postoperative parameters, pathological stage of disease (p-stage) and pT were the significant prognostic indicators (HR 2.1 and 2.42, respectively). CONCLUSIONS: In the present study, concerning surgically treated NSCLC patients, preoperative CRP > 10 mg/L and Cyfra 21-1 > 2 ng/mL were the only negative prognostic indicators, while pT and p-stage were significant postoperative prognostic indicators.

MATERIAL AND METHODS: Eligible patients had an average age of 64.8 years and smoked at least 10 pack-years. COPD was defined according to GOLD fixed cut-off criterion FEV1/FVC < 0.70. In all patients postbronchodilator spirometry was performed. Categories were defined with the mMRC dyspnoea scale and CAT scale. COPD exacerbations in the previous year and lung function were evaluated. Statistical comparisons were done using t-student test. RESULTS: 315 COPD patients, 99 (31.4%) women and 216 (68.6%) men, were examined. Mean pack-years in the whole group was 47.1 ± 17.8. In women this figure was less than in men, 43.7 ± 19.2 vs 49.5 ± 16.5 (p > 0.05), respectively. At study entry, 144 subjects (45.7%) were current smokers, and the majority of them (n-87, 60.4%) belonged to category D - 26/66 (54.5%) women and 51/102 (50%) men. Based on spirometry alone, the patients were classified as moderate COPD 144 (45.71%), severe - 154 (48.89%), and very severe 17 (5.4%). According to the 2011 GOLD report stratification, 60 patients (19.04%) were graded as category A, 63 (20%) as category B, 24 (7.62%) as category C, and 168 (53.33%) as category D, although 21 (12.5% of them) were in category B, but the number of exacerbations classified them as category D. CONCLUSIONS: The COPD population is heterogeneous in reference to the symptoms, value of FEV1, and susceptibility to exacerbations. Clinical symptoms assessed using validated questionnaires characterized COPD patients better than the value of spirometric parameters (which are necessary for diagnosis of this disease). Some patients were difficult to classify, especially those belonging to category C.

Almost 30% of cases of tuberculosis are known to be sputum smear negative. There is a diagnostic dilemma in such cases leading to inadvertent delays in management of these cases. The present study was planned to assess the role of bronchoscopy in immediate diagnosis of smear negative pulmonary tuberculosis. MATERIAL AND METHODS: The present study is a retrospective analysis of 132 sputum smear negative tuberculosis suspects who underwent bronchoscopic evaluation during the period 2002-2013. The diagnosis of tuberculosis was based on the finding of bacilli in aspirate or in tissue biopsy or the demonstration of caseous necrosis on tissue biopsy. RESULTS: The present study showed that bronchoscopy could lead to immediate, accurate diagnosis in 68.2% of suspected smear negative cases. Bronchial aspirate and bronchoalveolar lavage alone were diagnostic in 51.5% of such cases while tissue biopsy added to the yield in another 16.5% cases. CONCLUSIONS: The results of the present study suggests an important place of bronchoscopy in immediate diagnosis of suspected smear negative tuberculosis, thus avoiding inadvertent delays in diagnosing and instituting appropriate treatment.

The patients diagnosed with tuberculosis in the higher notification rate areas were younger and there were more cases of primary tuberculosis (tuberculous pleurisy and tuberculosis of chest lymph nodes) than in the patients diagnosed in the lower notification areas. The aim of the present study was to assess the possible causes of the different epidemiological situation of tuberculosis in various regions of Poland. MATERIAL AND METHODS: Analysis was done at the same regions as in the previous paper. A comparison was made between two groups: Group I, which included three voivodeships with higher rates of notification, from 23.7 to 32.3/100,000 (mean rates in the analysed period of time); and Group II, which included five voivodeships with lower notification rates (mean rates from 12.2 to 18.6/100,000). The wealth of the regions (GDP, gross domestic product per capita), the level of unemployment, and social status of the patients were analysed. We compared the population density in both regions. The results of treatment in both regions were also analysed. RESULTS: We did not find any differences in GDP and unemployment rates between the compared regions. The results of treatment were different in particular regions, but there was no clear tendency for worse results in voivodeships in Group I compared to voivodeships in Group II. However, the number of patients lost from observation was significantly higher in the regions from Group I than in those from Group II. There was also a significantly higher death rate from tuberculosis in younger patients (£ 59 years) from Group I than from Group II. This is additional proof that the epidemiological situation in the two regions was different. Finally, we found that the mean density of population in the regions from Group I was higher than that from Group II. The density of population may influence transmission of tuberculosis. There is also the possibility that the differences in the epidemiological situation in various regions of Poland are caused by historical events. In the past the epidemiological situation of tuberculosis was much worse in the east of Europe than in the west. Just after the Second World War, according to the changes of the Polish territory, many Polish citizens (mainly ancestors of those from Group I) were displaced from the east to the west. CONCLUSIONS: In conclusion, the greater number of patients lost from observation, together with the higher density of population in the regions from Group I in comparison with those from Group II, seems to be partly responsible for the difference in the epidemiological situation in the two regions. It is also possible that some patients from Group I are more susceptible to infection and disease caused by Mycobacterium tuberculosis due to their ancestors, who lived in the east of Europe.

This naturally imposes covering patients with bronchial asthma with a holistic model of care. Assessment of health-related quality of life (HRQoL) is one component of this model. HRQoL of asthma patients can be determined with an array of generic instruments, e.g. Medical Outcomes Survey Short Form 36 (SF-36), EuroQoL questionnaire (EQ-5D) or World Health Organization Quality of Life Questionnaire (WHOQOL), as well as with the specific tools, among which Saint George's Respiratory Questionnaire (SGRO) and Asthma Quality of Life Questionnaire (AQLQ) belong to the most widely used. HRQoL is significantly associated with the degree of asthma control. However, literature data suggest that a determination of HRQoL alone, with either specific or generic instrument, can be insufficient, as the level of health-related quality of life turned out to be modulated by three groups of factors: 1) demographic characteristics of patients, 2) clinical parameters, and 3) personality traits of respondents. Due to particularly strong effect of psychological characteristics on the quality of life of patients with bronchial asthma, also the level of depressiveness should be examined along with the HRQoL determination. Furthermore, complex assessment of the quality of life and its determinants should be conducted longitudinally, either in individual patients or in epidemiological studies.

Equally unclear is the role of medications used for bowel disease treatment in lung disease development. We present three patients with ulcerative colitis, all treated with mesalazine, in whom unexplained lung disease developed. Due to different clinical and radiological presentation, different conditions were initially placed on the top of the differential list in each of them. The outcome was favourable in all patients despite differences in management. We compared our patients with similar cases from literature. We show the level of difficulty and complexity in the issue of lung disease in patients with inflammatory bowel disease.

Chronic active Epstein-Barr virus infection (CAEBV) is associated with multiple life-threatening conditions, including interstitial lung disease with fibrosis and lymphoid and lymphohistiocytic infiltrations. We report on a pediatric patient in whom CAEBV resulted in severe pneumopathy with a fatal outcome.

The typical clinical scenario, such as chest retractions, tachypnoea, hypoxaemia, crackles, characteristic changes in high-resolution computed tomography and histological examination of the lung parenchyma, is the cornerstone for diagnosis. In the article, the authors describe clinical manifestation of neuroendocrine cell hyperplasia and a present case of an infant with this rare interstitial lung disease.

MATERIAL AND METHODS: The study group consisted of 62 non-small cell lung cancer patients, (21 women and 41 men), aged 51-84 years, hospitalised due to the chemotherapy. The survey included SF-20 test and a questionnaire prepared by the authors. RESULTS: The most frequent adverse events indicated by the patients were: weakness (79%), nausea and vomiting (77%), loss of appetite (56%) and diarrhoea (45%). It was found that the side-effects of chemotherapy were not dependent on age (p = 0.9882) or sex (p = 0.9968). The chemotherapy negatively influenced the quality of the patients' life (p < 0.000001). It was shown that there is a statistically significant correlation between age and limitations on social roles, professional life and performing housework (p < 0.0133), and also the inability to perform specific types of activities (p < 0.01). CONCLUSIONS: The results of the study show that chemotherapy of non-small cell lung cancer was connected with decreased quality of life, especially in patients over 65 years of age. The patients under 65 years of age could not deal with the disease in respect of psychological aspects, whereas people over 65 years of age had greater problems with physical, social and professional functioning.

The aim of the study was to assess whether there are elements that might confirm that these differences are true. To answer this question, we compared the population of TB patients from regions with higher notification rates to the population of patients from regions with lower notifications rates. The data collected during three consecutive years were analysed. We selected for comparison the regions with the lowest and highest notification rates and those in which the notification rates for 3 years (2010-2012) were relatively stable. MATERIAL AND METHODS: Eight regions were chosen: three regions (Group I) with high notification rates (from 23.7 to 32.3/100,000 - mean rates in the analysed period of time) and five (Group II) with low notification rates (mean rates from 12.2 to 18.6/100,000). RESULTS: It was found that the proportion of sputum culture-positive patients was significantly higher in Group II. Thus, the difference in the notification rate of cases with culture-confirmed tuberculosis was smaller than the difference in the whole notification rate. Nevertheless, it was still significant. Tubercle bacilli in patients from Group I were significantly more often resistant to one drug. The incidence of chronic fibro-cavernous disease and of tuberculous pneumonia was significantly higher in Group I. The proportion of patients with symptoms was higher in Group I than in Group II. In addition, patients in Group I had the so-called primary tuberculosis (tuberculous pleuritis and tuberculous lymphadenopathy in the chest) significantly more often. It was also found that among patients from Group I there were significantly more children, more (though not significantly) youngsters and significantly fewer elderly patients. CONCLUSIONS: Based on these observations, it was concluded that there is a real difference in the epidemiological situation of tuberculosis in the selected regions of Poland with high and low rates of notification. Possible causes of this situation will be presented in a following publication.

Therefore, the detection of P.a. as early as possible is an important goal of care. Regular determination of antibodies to P.a. antigens in serum may be useful in patients who have not yet been infected or were infected intermittently. The aim of the present study was to assess the concentrations of antibodies to selected antigens of P. aeruginosa in the serum of children with CF and with known status of P.a. infection. MATERIAL AND METHODS: The study was performed in 111 CF patients (27 not infected with P. aeruginosa, 29 with intermittent infection and 55 with chronic infection). The concentrations of IgG antibodies to the alkaline protease (AP), elastase (ELA) and exotoxin A (Exo-A) were measured. The increased concentration of antibodies was defined as exceeding 500 units (according to the manufacturer). The results of antibodies assessment were analysed according to previous infection status and the results of present culture. RESULTS: At the time of the study, P.a. was cultured from sputum of 57 patients: 9 out of 29 (31%) with intermittent infection, and 48 out of 55 (87%) with chronic infection. Increased concentrations of antibodies to one or more P.a. antigens were found in 60 patients, and to all three types of antigens in 30 patients. Increased serum antibody concentration was found significantly more often in the patients with chronic P.a. infection compared to those with intermittent infection (82% vs. 35%, p = 0.0001). In the patients with chronic P.a. infection (especially with mucoid type), serum antibody concentrations were significantly higher than in other patients. Higher concentrations of antibodies were also found in the patients with positive result of P.a. culture at the time of the study, compared to those with negative culture. In 19% of patients not infected with P.a., increased serum antibodies to at least one P.a. antigen were found. The clinical significance of such findings is unclear and needs further investigation. CONCLUSIONS: In the present study, the increased serum concentrations of IgG antibodies to P. aeruginosa antigens (AP, ELA and Exo-A) were found most often in the patients with chronic P.a. infection and in those in whom P.a. (especially mucoid type) was cultured at the time of the study. The clinical significance of the elevated antipseudomonal antibodies level in 19% of the patients never infected with P.a. is unclear and needs further investigation.

Impulse oscillometry (IOS) may be an interesting alternative for spirometry as the examination is made during quiet breathing and gives information about resistive properties of the respiratory system. MATERIAL AND METHODS: This work presents the results of oscillometric measurements made in 277 patients aged 65-96 years, in whom spirometry was also performed. RESULTS: Resistances measured with IOS (R5, R5-R20) and the resonant frequency Fn correlated significantly with FEV1 (r = -0.503; -0.570 and -0.673, respectively). A comparison of the results from patients with airway obstruction confirmed in spirometry with those of the non-obstructed group showed highly significant differences in mean values of oscillometric parameters (p < 0.001). CONCLUSIONS: As R5-R20 is regarded as a measure of peripheral airways resistance, IOS may serve as an interesting complementary or alternative method for spirometry in elderly subjects for evaluation of the state of respiratory system.
