Fire-eater's lung

Fire eater's lung (FEL) is an acute hydrocarbon pneumonitis caused by aspiration or inhalation into airways of liquid hydrocarbons. This disorder is classified into distinct form of chemical toxic pneumonitis. An amateur fire-eater is presented in this work. He accidentally aspirated into airways about 1/3 of glass of grill lighter fluid composed of mixture of liquid hydrocarbons. A few hours after this incident he had severe symptoms like weakness, high temperature, midsternal pleuritic chest pain, myalgia of the back, shortness of breath, and dry cough. Radiologic examination revealed consolidations with well-defined cavitary lesions (pneumatoceles) in lower lobes mainly in the left lower lobe. After one week of this event clinical improvement was observed. The lesions resolved nearly completly during three months. The review of the literature connected with fire-eater's lung is also presented.

Severe congestive heart failure as the main symptom of eosinophilic granulomatosis and polyangiitis (Churg-Strauss syndrome)

Patients with cardiovascular symptoms are mainly diagnosed in cardiological wards. However, sometimes the other reasons for acute coronary syndrome and heart failure are found. One of such reasons is hypereosinophilia which can be recognized if number of blood eosinophils exceeds 1500/mm3. High eosinophilia is connected with production of cytotoxic eosinophilic proteins which can cause eosinophilic vasculitis or eosinophilic myocarditis. One of the better known hypereosinophilic syndromes is EGPA described by the pathomorphologists Churg and Strauss. The further research works allowed for the clinical characteristics of patients with EGPA. In the course of this disease the following three phases were recognized : prodromal-allergic, eosinophilic, vasculitic. The definitive diagnosis can be established only in the third phase, when vasculitis causes organ involvement. Besides symptoms of the respiratory tract (asthma, nasal polyps, eosinophilic lung infiltrations) also cardiovascular symptoms, gastrointestinal tract symptoms, as well as skin lesions and kidneys involvement can appear. The most dangerous for patients is involvement of the nervous and cardiovascular systems. We present a patient with asthma and eosinophilia in whom EGPA was diagnosed in the course of acute recurrent substernal chest pain, with subsequent signs of cardiac insufficiency.

[Pneumocystis pneumonia in HIV-infected patients with cytomegalovirus co-infection. Two case reports and a literature review]

Pneumocystis pneumonia (PCP) is one of the infectious lung diseases diagnosed in HIV-infected patients. The pathogen responsible for the development of this opportunistic infection is an atypical fungus called Pneumocystis jiroveci. PCP remains the most common disorder diagnosed at the onset of acquired immunodeficiency syndrome (AIDS), especially in individuals not aware of their HIV infection. The most important risk factor of PCP development in HIV-infected person is the decrease of T CD4+ cell number below 200/mcL. Clinical symptoms consist of: chronic cough, dyspnoea and weakness. Arterial blood gas analysis often reveals the presence of hypoxaemia, and high-resolution computed tomography imaging shows diffuse ground glass opacities. Treatment is based on intravenous administration of trimetoprim-sulfamethoxasole. In patients with moderate and severe symptoms of PCP it is recommended that corticosteroids are used. Co-infection with cytomegalovirus (CMV) is a poor prognostic sign in PCP. CMV-related organ disease should be suspected in patients with T CD4+ cell number lower than 50/mcL. It is arguable whether CMV infection in symptomatic PCP patients should be treated. There are suggestions that corticosteroids used in PCP patients with CMV co-infection could promote the development of CMV pneumonia. In the present paper we present two patients with PCP, unaware of their HIV infection. In both cases a CMV co-infection was found.

Association of Genetic Dependences between Lung Cancer and Chronic Obstructive Pulmonary Disease

Introduction: Recent studies have shown an increased risk of lung cancer in patients with bronchial obstructive changes, including patients with COPD. It seems that there are common factors of pathogenesis of both diseases associated with oxidative stress. In the present paper the genes linked to the repair of oxidative damage of DNA, associated with cancer, of iron metabolism and coding proteolytic enzymes were assessed. Material and Methods: The study was conducted in two groups of patients: 53 patients with non-small cell lung cancer and chronic obstructive pulmonary disease, and 54 patients only with chronic obstructive pulmonary disease. The polymorphisms of the single nucleotide were determined in the case of the majority of genes using the PCR-RFLP method. The statistical analysis of quantitative variables was executed using the Mann-Withney U-test and the test of medians; the analysis of genetic variables was executed using the χ² test. Results: Regarding the polymorphisms of genes involved in iron metabolism, statistically significant differences between the two groups have been demonstrated only in the case of haptoglobin gene HP1/2. A higher incidence of form 1/1 was found in patients with COPD and a higher incidence of form 1/2 in patients with lung cancer and COPD. Analysis of gene polymorphisms of proteolytic enzymes and inhibitors of the enzyme gene showed statistically significant differences between the two groups only for the MMP3 gene 6A/5A. In the case of the MMP12 gene polymorphism (A-82G) a tendency toward differences in the occurrence of specific alleles was identified. Conclusions: These results indicate that patients with coincidence of COPD and lung cancer have disorders of the genes involved in iron metabolism, and they have different genetic polymorphisms of proteolytic enzymes comparing to COPD patients.

Association of genetic dependences between lung cancer and chronic obstructive pulmonary disease

INTRODUCTION

Recent studies have shown an increased risk of lung cancer in patients with bronchial obstructive changes, including patients with COPD. It seems that there are common factors of pathogenesis of both diseases associated with oxidative stress. In the present paper the genes linked to the repair of oxidative damage of DNA, associated with cancer, of iron metabolism and coding proteolytic enzymes were assessed.

MATERIAL AND METHODS

The study was conducted in two groups of patients: 53 patients with non-small cell lung cancer and chronic obstructive pulmonary disease, and 54 patients only with chronic obstructive pulmonary disease. The polymorphisms of the single nucleotide were determined in the case of the majority of genes using the PCR-RFLP method. The statistical analysis of quantitative variables was executed using the Mann-Withney U-test and the test of medians; the analysis of genetic variables was executed using the chi² test.

RESULTS

Regarding the polymorphisms of genes involved in iron metabolism, statistically significant differences between the two groups have been demonstrated only in the case of haptoglobin gene HP1/2. A higher incidence of form 1/1 was found in patients with COPD and a higher incidence of form 1/2 in patients with lung cancer and COPD. Analysis of gene polymorphisms of proteolytic enzymes and inhibitors of the enzyme gene showed statistically significant differences between the two groups only for the MMP3 gene 6A/5A. In the case of the MMP12 gene polymorphism (A-82G) a tendency toward differences in the occurrence of specific alleles was identified.

CONCLUSIONS

These results indicate that patients with coincidence of COPD and lung cancer have disorders of the genes involved in iron metabolism, and they have different genetic polymorphisms of proteolytic enzymes comparing to COPD patients.

Modulatory effect of sera from sarcoidosis patients on mononuclear cell-induced angiogenesis

Sarcoidosis (SAR) is a systemic granulomatous inflammatory disease characterized by recruitment and activation of peripheral blood mononuclear cells to the sites of disease. Neovascularisation is a principal vascular response in chronic inflammation and hypoxia. The aim of the study was to evaluate the effect of sera from sarcoidosis patients on angiogenic capability of different subsets of normal peripheral human mononuclear cells (MNC) in relation to IL-6 and IL-8 serum levels, to radiological stages of disease and to the presence of extrapulmonary changes. Serum samples obtained from 42 sarcoidosis patients were examined. There were 12 patients in stage I, 16 patients in stage II, and 14 in stage III. In order to quantify angiogenesis, a leukocyte-induced angiogenesis assay was performed by a method of Sidky and Auerbach. MNC were depleted in monocytes by glass adherence and phagocytosis of iron particles techniques. IL-6 and IL-8 in sera from sarcoidosis patients were evaluated by an ELISA-based assay. Sera from sarcoidosis patients enhanced angiogenic capability of normal MNC significantly stronger than sera from healthy donors (P<0.001). Angiogenic activity of sera in sarcoidosis depended on the stage of disease and appeared most pronounced in stage II (P<0.05). Sera from patients with extrapulmonary changes exerted stronger effect on angiogenesis than sera from patients with thoracic changes only (P<0.001). IL-6 and IL-8 serum level correlated with each other, but no correlation was found between IL-6 and IL-8 serum level and angiogenic activity of the examined sera. Removal of monocytes from MNC eliminated the effect of sera from sarcoidosis patients on angiogenesis compared with the effect of these sera on intact MNC (P<0.001). Sera from sarcoidosis patients and from healthy people constitute a source of mediators participating in angiogenesis. Sera from sarcoidosis patients prime monocytes for production of proangiogenic factors.

Invasive Aspergillosis (IA) In Patients Treated in the Institute of Tuberculosis and Chest Diseases in the Years 1993–2005—Diagnostic Problems

The aim of this study was to present the diagnostic problems in pts treated for invasive aspergillosis (IA) in the Illrd Clinic of the Institute of Tuberculosis in the years 1993–2005. The material consisted of clinical documentation of 18 pts. 15 out of 18 pts (83.4%) died. In all those cases autopsy examination was done. In 13 pts IA was the main and in another 2 only the accessory cause of death. AU pts were treated with corticosteroids and/or cytostatic drugs because of lung cancer (13 pts), haematologic disorders (1 pts), Wegener's granulomatosis (3 pts) and idiopathic pulmonary fibrosis (1 pts). In 13 out of 18 pts granulocytopenia was revealed (on an average from 0.008 × 109/L to 0.95 × 109/L) one month before death. In 13 pts IA was limited to the lungs, in 5 others there were also fungal lesions in brain, kidneys, liver, spleen, pleura, pericardium and heart. Pts with disseminated fonn ofIA had significantly lower granulocyte count and were treated with higher doses of corticosteroids than others. Immunosupressive drugs and granulocytopenia can be regarded as predisposing factors. IA was diagnosed before death only in 5 out of 18 pts. This was mainly caused by the lack of the symptoms of in­fection (4 pts) and negative results ofmycological (6 pts) and serological examination (8 pts). We should underline that mycological examination was only done in 11 pts and serological examination of blood for fungal antigen only in 6 pts. We conclude that mycological infection ought to be searched in all pts treated with high doses of corticosteroids and those with prolonged granulocytopenia, especially if they have the symptoms of infection which does not respond to antibiotic therapy.

[The significance of the serum tumour markers as a prognostic and predictor factors in nonsmall cell lung cancer patients]

The aim of the study was to assess the role of serum tumour markers (NSE, Cyfra 21-1, CEA, LDH, ferritin) as a prognostic and predictive factors in 79 patients with advanced NSCLC treated with chemotherapy. Objective response to treatment was significantly more frequent in the patient with serum NSE > 12.5 ng/ml. Progression of disease was observed more often in patients with serum Cyfra 21-1 >10 ng/ml or LDH >480 U/L. CEA >3 ng/ml, LDH >480 U/L, for coefficient >1, NSE >20 ng/ml and Cyfra 21-1 >10 ng/ml had a negative impact on survival in univariate analysis. Independent negative prognostic significance of fer coefficient >1 was confirmed by multivariate analysis.

Cellular components of the bronchoalveolar lavage correlate with lung function impairment and extrapulmonary involvement markers in active sarcoidosis

Sarcoidosis is a chronic inflammatory multiorgan disease of unknown origin. Our previous study demonstrated a significant correlation between the relative count of non CD4(+), non CD8(+) lymphocytes in bronchoalveolar lavage of active sarcoidosis patients and proangiogenic activity of BAL homogenates. The aim of the present study was to evaluate in a group of 40 patients with active sarcoidosis the possible relationship between the intensity of alveolitis, particularly the non CD4(+), non CD8(+) lymphocyte subset, and other parameters characterizing the level of pulmonary (lung function tests) and extrapulmonary (spleen longitudinal dimension) disease activity. We found that the relative count of non CD4(+), non CD8(+) lymphocytes in BAL correlated positively with spleen size (r=0.50, P<0.01) and negatively with static compliance (r=0.43, P<0.05). We concluded that the lymphocytes belonging to the non CD4(+)non CD8(+) subset participate in the inflammatory process in sarcoidosis. However, more detailed phenotypic and functional characteristics of this cellular population are needed.

[Organizing pneumonia--analysis of 18 own cases]

Organizing pneumonia (OP) is a rarely diagnosed disease, however the incidence ratio was estimated as 6-7/100000. Disease can occur in cryptogenic form or as a secondary reaction to various noxious agents, drugs, and ionising radiation, as a concomitant disease to infections, lympho- and myeloproliferative disorders, and connective tissue diseases. Symptoms of OP are non-specific therefore lung biopsy and histological examination are necessary for diagnosis. Eighteen cases of OP, 15 women and 3 men, aged 40 to 76 years, are presented with analysis of clinicopathological characteristic and therapeutic problems. In all cases diagnosis was confirmed by open lung biopsy. In one case radiotherapy and in one trastuzumab treatment was the cause of OP. In further 3 women antibodies against Chlamydia pneumoniae and in one--against Mycoplasma pneumoniae were found in serum. Probably Hashimoto disease was the cause of one case. In 12 patients the OP was idiopathic. Majority of patients were treated by prednisone (0.5 mg/kg). In one patient regression without any treatment was noticed and in other one--after cessation of trastuzumab. Five women were treated by clarithromycin. In 3 of them regression was observed but in other 2 corticotherapy was necessary. The observation period ranged from 1 month to 9 years, mean 34 months.

[Pulmonary mycobacterioses--frequency of occurrence, clinical spectrum and predisposing factors]

Various types of non-tuberculous mycobacteria can be the aetiologic factors of chronic lung infections especially in patients with underlying chronic lung diseases. The aim of this study is to present the cases of pulmonary mycobacterioses observed in Institute of Tuberculosis and Lung Diseases in the years 1995-2001. There were 23 patients, 12 men and 11 women in the age between 35-77 years, mean 56 years. 16 out of 23 patients had underlying respiratory problems, mainly healed tuberculosis (7) and COPD (6). Two additional patients suffered from other diseases with potential immunosuppression (leukopenia). In 5 patients no disease other than mycobacteriosis was found, but they were chronic smokers. In 19 cases cough and expectoration of purulent sputum lasting from several months to several years was observed. In 5 patients onset of disease was acute or subacute with high fever. Eight patients had haemoptysis. In chest X-ray pathological lesions including (18 cases) lung cirrhosis (10) and cavities (15) were found. In 4 cases disseminated bronchiectases with small nodules were the main radiologic feature. Mycobacteriosis was caused by M. kansasii in 11 cases, by M. intracellularae in 6, by M. xenopi in 5 and by M. scrofulaceum in 1 case.

[Invasive aspergillosis in autopsy material of patients treated at the Institute of Tuberculosis and Chest Diseases during the years 1993-2000]

The aim of this paper is an analysis of clinical documentation and results of autopsy of 21 patients (pts) who died of invasive aspergillosis (IA) in the Institute of Tuberculosis and Chest Diseases in years 1993-2000 and the assessment of predisposing factors for IA. In 17 pts IA was the main and in other 4 only an accessory cause of death. All pts were treated with corticosteroids and/or cytostatic drugs--because of lung cancer (11 pts), cancer in other site (2 pts), haematologic disorders (2 pts), Wegener's granulomatosis (1 pt), polymyositis (1 pt), idiopathic pulmonary fibrosis (1 pt) and other diseases (3 pts). In 15 out of 21 pts granulocytopenia was revealed (from 0.008 x 10(9)/L to 0.82 x 10(9)/L) on an average one month before death. In 15 pts IA was limited to the lungs, in 6 others there were also fungal lesions in brain, kidneys, liver, spleen and heart. Pts with disseminated form of IA had significantly lower granulocyte count and were treated with higher doses of corticosteroids than others. Immunosuppressive drugs and granulocytopenia can be regarded as predisposing factors. Fatal course of IA depended also on the late diagnosis.

[Pulmonary amyloidosis--own experience]

Three cases of amyloidosis were described. In all diagnosis was confirmed by histological examination. There was amyloidosis limited to the lungs in 2 cases and in 1 generalised. In 1 patient lobectomia was performed. Next 2 pts were treated with prednisone and cytostatic drugs (melphalane and cyclophosphamide).

[The effect of small cell lung cancer extension on secretion of interleukin-2 (IL-2) and interferon gamma (IFM gamma) in whole blood culture stimulated with mitogens]

The aim of this study was to assess the role of SCLC extension on II-2 and IFN gamma secretion in whole blood cell cultures stimulated with mitogens. Material consisted of 42 SCLC patients, 19 with extensive and 23 with limited disease. In 22 patients partial or complete regression of tumour occurred after treatment. There was a tendency to lower II-2 and IFN gamma secretion before treatment in patients with extensive disease in comparison to those with limited lesions but this was not statistically significant. The ability to secrete cytokines in 22 patients after partial or complete regression of tumour decreased or increased but median values after treatment were not statistically different from those before treatment.

[The relation between lymphocyte profile in BALF and the course of sarcoidosis based on short term observation]

The aim of this study was to assess how the extent of the number and percentage of lymphocytes in BALF and also the CD4 to CD8 ratio can help to predict the short outcome in sarcoidosis. Material consisted of 74 patients, 39 men and 35 women in the age from 23 to 58 years. 11 patients had chest lesions in stage I, 43 in stage II and 20 in stage III. Clinical markers of activity (fever, erythema nodosum) were present in 22 cases. Extrathoracic lesion were present in 31 and abnormal pulmonary function in 30. In all patients BAL was done before treatment and lymphocyte count, percentage and CD4/CD8 ratio was calculated. 50 patients were treated with corticosteroids and 24 were observed without treatment. After 6-12 month of observation regression of sarcoid lesions was observed in 46 of 50 patients treated with corticosteroids and in 17 out of 24 patients observed without treatment. There were no differences in lymphocyte count and percentage in BALF and in the short term outcome between group treated with corticosteroids and without treatment. The patients in whom regression of lesions was observed have however significantly higher CD4/CD8 ratio than others.

Interferon gamma and interleukin-2 secretion in whole blood cell cultures from small-cell lung cancer patients

Secretion of interleukin-2 (IL-2) and interferon-gamma (IFNgamma) in whole blood cell cultures after phytohemagglutinin (PHA) and pokeweed mitogen (PWM) stimulation was evaluated in 42 small-cell lung cancer patients before treatment. Blood cultures from patients with extensive and limited disease have lower IFNgamma secretions after PWM stimulation and lower IL-2 secretions after PWM and PHA stimulation, but this was not statistically significant. IFNgamma but not IL-2 secretion was significantly higher after PWM stimulation in cultures from patients with better clinical performance status (0 + 1, WHO scale). Blood cultures from patients with tumor regression after treatment had a higher secretion of IFNgamma after PWM stimulation. In contrast, blood cultures from patients with a poor prognosis had significantly lower IL-2 and IFNgamma secretions after stimulation with PWM, and a lower IL-2 secretion after stimulation with PHA.

[Secretion of interleukin-2 (IL-2) and interferon (IFN gamma)in whole blood cell culture stimulated with mitogens in patients with lung neoplasms]

The aim of this study was to compare the ability of blood lymphocytes from lung cancer patients to secrete interleukin-2 (IL-2) and interferon gamma (IFNg) upon stimulation with mitogens with that of healthy donors. 42 patients with small cell lung cancer (SCLC), 30 patients with non small cell lung cancer (NSCLC) and 30 healthy donors were studied. The test was done in lung cancer patients before treatment. IL-2 and IFNg levels were measured with Elisa ready kits (Genzyme) in the supernatants of whole blood culture after stimulation with Pokeweed (PWM) and Phytohemagglutinin (PHA) mitogens. The results of the cytokine levels after stimulation were not normally distributed and thus were transformed to logarthms for statistical evaluation. The t-test for transformed results were used to asses the difference between groups. The median level of IFNg in the supernatant of whole blood cultures was significantly lower in lung cancer patients than in healthy blood donors both after PWM as well as after PHA stimulation. When patients with NSCLC and SCLC were regarded separately the lower level of IFNg in comparison with healthy donors was found in the supernatant of the blood cultures only after stimulation with PWM. The median level of IL-2 in the supernatant of whole blood culture in lung cancer patients was lower than in healthy blood donors only after PWM stimulation. The same was true for SCLC patients. In NSCLC IL-2 levels were significantly lower after stimulation with PWM as well after PHA stimulation.

IN CONCLUSION

secretion of IL-2 and IFNg in whole blood culture after mitogen stimulation in lung cancer patients is significantly lower than in healthy donors. No significant differences between SCLC and NSCLC were found.

[Pseudochylothorax during the course of rheumatoid arthritis]

Psudochylothorax is uncommon among pleural fluids. It can be observed during tuberculosis or rheumatoid arthritis in majority. A case of a 62 years old man with chronic pleural fluid is presented. Patient had rheumatoid arthritis diagnosed 40 years ago. For last 13 years symptomsless bilateral pleural fluid was observed. Antituberculous drugs were used without success. Plural fluid obtained after puncture had high level of cholesterol with it[symbol: see text]s crystals, without chylomikrons and triglycerides. Diagnosis of pseudochylothorax in the course of rheumatoid arthritis was established. After plural puncture fluid was removed and did not appear later. Differential diagnosis of pleural fluids is presented.

[Pulmonary thromboembolism as the main or secondary cause of death in patients treated for small cell lung cancer]

The aim of this study was to assess the frequency of pulmonary thromboembolism in small cell lung cancer (SCLC) patients (pts) treated in the Institute of Tuberculosis and Chest Diseases in the years 1980-1994. The second aim was to assess whether the occurrence of thromboembolism is connected with the progression of cancer. Pulmonary thromboembolism was recognised in 17 out of 845 pts (2.01%) treated for small cell lung cancer, that is in 2.01% of pts. The frequency of thromboembolism was 8% among patients in which autopsy was done. Pulmonary thromboembolism occurred in 7 pts during progressive disease but also in 9 with partial or complete regression of SCLC. The potential role of chemo- and radiotherapy in the development of thromboembolism in the last group was discussed.

[Ocular manifestations in sarcoidosis]

PURPOSE

The ophthalmic examination of patients with diagnosed systemic sarcoidosis.

MATERIAL AND METHODS

33 patients (17 women, 16 men), aged 22-60 years had ophthalmic examination (visual acuity, anterior and posterior segment evaluation, applanation tonometry). In 8 patients repeated examination was performed (duration of observation: 2-31 months).

RESULTS

In 27 patients no characteristic features of ocular sarcoidosis were found. In 6 persons (18.2%) variety of ocular lesions was recognized (nodular infiltrations of the eyelids, chronic uveal inflammation, signs of anterior and posterior uveitis in the past, optic disc oedema). In 3 cases ocular lesions preceded the signs of systemic sarcoidosis. This emphasizes the importance of the routine ophthalmic examination of patients with suspected or proven sarcoidosis.

[Usefulness of measuring serum IGG antibodies against A60 mycobacterial antigen for diagnosis of tuberculosis]

Measurement of antimycobacterial antibody may be used as potential diagnostic tool in tuberculosis. The aim of the study was to evaluate the diagnostic value of serum IgG level against A60 mycobacterial antigen measured by ELISA method. Material consisted of 144 persons divided into 5 groups (76 tuberculosis patients, 20 sarcoidosis patients, 17 lung cancer patients, 8 patients with mycobacterial infections other than tuberculosis and 23 healthy controls). In the tuberculosis group there were 50 culture positive cases and 26 culture negative ones, 43 new cases and 32 chronic cases. Positive results were obtained in 51% of tuberculosis patients. Sensitivity increased to 62% in culture positive group and 63% in chronic cases. Specificity of the test was 96%. The results indicate that Immunozyme Mycobacterium test is a valuable tool in tuberculosis diagnosis.

[Coronary artery vasospasm as a cause of chest pain in a patient with small cell lung cancer]

Case of 67 years old man with small cell lung cancer and coronary artery spasm has been presented. After administration calcium channel blockers and nitroglycerin very good therapeutical effect was achieved.

Tuberculosis in the autopsy material: analysis of 1500 autopsies performed between 1972 and 1991 in the Institute of Tuberculosis and Chest Diseases, Warsaw, Poland

SETTING

The present study is based on 1500 autopsies done in the Institute of Tuberculosis and Chest Diseases Warsaw, Poland during the years 1972-81 and 1982-91.

OBJECTIVE

To assess the correctness of tuberculosis diagnosis before death in the above mentioned time periods.

DESIGN

The autopsy reports were examined for the diagnosis of active tuberculosis proved by microscopy. The form and localisation of tuberculosis was assessed. The postmortem diagnosis was compared with clinical diagnosis. In those cases in which tuberculosis was not recognised before death the possible causes of this failure were analyzed.

RESULTS

Active tuberculosis was found in 119 cases, 7.9% of all autopsies. It was localised in the lungs exclusively in 72 cases, in lungs and in extrapulmonary sites in 45 and in extrapulmonary sites only in 2. The frequency of active tuberculosis was the same for the two periods under evaluation. Tuberculosis was however not recognised before death in a much higher proportion of cases in 1982-92 (54%) than in 1972-81 (24%). The main cause of diagnostic failure was connected with atypical localisation of lesions on chest X-ray and with dissemination outside the lungs. Previous tuberculosis was a factor which facilitated the diagnosis of tuberculosis.

CONCLUSIONS

In parallel with the decline of tuberculosis incidence in Poland, many doctors lack experience in diagnosing this disease, especially in cases with atypical X-ray presentation and with extrapulmonary localisation. This may lead to late or even very late diagnosis and have a significant impact on the epidemiological situation.
