[Prevalence of G20210A prothrombin gene mutation in Poland].

The G20210A mutation of the prothrombin (PT) gene has recently been identified as a risk factor for venous thromboembolism (VTE). This mutation was shown to be present mainly among Caucasian populations, with a higher frequency in southern than in northern Europe. The aim of our study was to determine the prevalence of the PT 20210A allele in the Polish general population and in patients with a history of venous thrombosis. The patient group comprised 323 subjects with VTE before the age of 45, recurrent VTE or thrombosis in an unusual site. The control group consisted of 399 healthy individuals. Heterozygosity for the PT 20210A allele was found in 21 (6.5%) patients and 7 (1.8%) controls. In 7 (33.3%) of the 21 heterozygous patients the PT 20210A allele was associated with the factor V Leiden mutation, in 1--with the homozygous C677T mutation of the methylenetetrahydrofolate reductase (MTHFR), and in 1--with lupus anticoagulant. Our results indicate that the presence of the 20210A allele is a mild risk factor for venous thrombosis if not associated with other thrombophilic defect (odds ratio 2.2; 95% CI: 0.8-5.5). The risk is greater in double heterozygous carriers of the PT 20210A allele and factor V Leiden mutation.

[Secondary prophylaxis of venous thromboembolism: analysis of 49 fatal cases].

The analysis of 49 fatal cases of venous thromboembolism--VTE (15% of total ambulatory patients number during long observation was performed. The advanced age of patients, multiple risk factors, underlying circulatory and respiratory tract diseases, malignancies, previous episodes of VTE especially with secondary pulmonary hypertension were the most important factors determining fatal prognoses in those patients.

[Pulmonary embolism in malignancy of the lung: a retrospective clinical evaluation and pathomorphologic personal material].

The incidence and clinical significance of pulmonary embolism (PE) in pulmonary malignancy were analysed among 111 autopsy cases including: 65 primary and 24 metastatic lung cancer, 8 hematological malignancies and 14-malignant pleural mesothelioma. In 34 (31%) cases PE was found, in 4 (12%) patients cancer tissue emboli was documented. In nonsmall cell lung cancer the frequency of PE was 40%, compared to 24% in small cell, 25% in metastatic lung cancer and 14% in mesothelioma. Deep venous thrombosis of lower extremities was the source of thrombotic material in 35% cases. In remaining cases the sources of thrombotic material were different (caval vein inferior, superior, and their main branches, right heart cavities, pulmonary artery). In 8 patients with PE the acute form of DIC was observed. In 15 (44%) patients the clinical ante mortem diagnosis of PE was done. In 26% of all analysed cases PE was the direct cause of death. We concluded that PE is a frequent and dangerous complication of lung neoplasms. Clinical diagnosis can be extremely difficult.

[Secondary prevention by using oral anticoagulants in patients with clinically acute massive pulmonary embolism].

Oral anticoagulants are generally accepted as secondary prophylaxis in patients with thromboembolic disease. Long term oral anticoagulant treatment of 24 survivors of clinically acute massive pulmonary embolism (AMPE) was assessed. There were following indications for such a treatment: recurrent PE/DVT in history and/or continuous risk factors. In the group of survivors of AMPE with continuing risk factors or the recurrence of that disaster the long-term oral anticoagulant therapy is effective, relatively safe and therefore justified.

[Evaluation of agreement between clinical and pathomorphologic diagnosis of pulmonary embolism].

The rate of both: false-positive and false-negative diagnoses of pulmonary embolism (PE) is high. To determine the accuracy of the ante-mortem diagnosis of PE we reviewed 78 autopsies and compared the clinical and pathological diagnoses in that group. In 64 cases PE was diagnosed clinically: in 43 it was confirmed by autopsy (67%). In 21 cases (33%) the clinical diagnoses were false-positive. There were 57 pathological diagnoses altogether: in 14 cases (25%) the clinical diagnoses were false-negative. Among falsely diagnosed patients, the diagnoses of myocardial infarction, pneumonia and malignancy were most frequent. We tried to find some distinctive features separating the cases in the subgroups. Among them venous diseases were more frequent in PE than in falsely diagnosed patients.

[Incidence of pleural mesotheliomas in Poland (preliminary report)].

Mesothelioma is a rare malignancy, difficult to diagnose and rarely found in a population not exposed to asbestos. In the immediate past incidence rates of this disease have increased due to extensive use of this mineral in the industry of the 1950's. The aim of this study was to assess the incidence of mesotheliomas basing on results of a questionnaire posted in 1987 to all pneumonology clinics, oncological departments in Poland, and data from the Central Oncological Register from the years 1970-1985. Incidence of this malignant disease was 1-2 cases per 1,000,000 of general population during the years 1970-1985 and did not rise in 1986. Regional differences were observed, in some areas the incidence rate was 5-6 per 1,000,000. Data from the Occupational Medicine Institute disclosed in these regions more extensive industrial use of this mineral. The authors have also concluded that "at-life" diagnosis of mesothelioma rises, mainly due to the use of open pleural biopsy.

[Intensive treatment of respiratory failure--personal experiences].

Controlled oxygen-therapy was used in 30 out of 49 patients (61%) with the acute respiratory failure or exacerbations of the chronic respiratory failure treated at ICU (Group Y), while artificial ventilation in the remaining 19 patients (39%; Group B). An improvement was achieved in 70% of patients of Group A and 42% in Group B. Overall improvement was achieved in 59% of the treated patients. There were 69% of treated patients with infections. Totally 41% of the treated patients died (30% of Group A and 58% of Group B). An analysis of the results has been carried out in various subgroups of the treated patients, i.e. the acute and exacerbated respiratory failure as well as partial and complete respiratory insufficiency. The result of high risk patients have also been analysed. This subgroup included sudden cardiac arrest, shock and non-compensated acidosis. Favourable effects of the intensive care of patients with infections have been discussed with particular reference to the life hazard in case of septic complications. Emphasis is on the unfavorable effects of therapy in patients with respiratory failure complicated with pulmonary embolism. Indications to the use of respirator and complications of the artificial ventilation have been discussed.

[Respiratory failure treated at the intensive care unit "R" of the Internal Disease Clinic of the Institute of Tuberculosis and Pulmonary Diseases (1986-1987)].

A picture and clinical course of the acute and exacerbated chronic respiratory failure have been analysed. An analysis embraced a group of 49 patients, i.e. 16 percent of all patients treated at the Intensive Care Unit. Four subgroups were distinguished depending on the etiology of the disease in which infectious, thrombo-embolic, circulatory or toxic factors caused respiratory failure. An emphasis is on the prevalence of the infectious etiology of disease being noted in 65% of patients. Acute respiratory failure was observed in 37% of patients whereas exacerbation of the chronic respiratory failure in 63%. Complete respiration distress was noted in 55% of cases and partial respiratory failure in the remaining 45%. Gasometric differences characteristic for each subgroup of the patients have also been analysed. 41% of the patients died. The highest mortality rate was seen in pulmonary embolism complicating various pulmonary diseases. Sudden cardiac arrest, shock and not compensated acidosis have been most unfavourable factors in the prognosis.
