There is a correlation with lung pathologic physical findings, lower values of FEV1 (in a range of normal values) and the degree of nonspecific bronchial sensitivity as objective indices of activity of bronchial asthma. There is no correlation of these parameters with patient's symptoms as subjective indices of bronchial asthma.
Background/Aim. Lung cancer is one of the most common malignant tumors. About 80% of all lung cancers are non-small cell lung cancer (NSCLC). According to histopathological characteristics, the most common types of NSCLC are squamous cell carcinoma and adenocarcinoma. The aim of this study was to evaluate the overall survival rate in the NSCLC patients initially received surgery according to its histopathological type and T-primary tumor, N-regional lymph nodes, M-distant metastasis (TNM) stages which were treated with surgical treatment, and after that, according to the TNM stage, chemotherapy protocols and/or radiation therapy. Methods. This retrospective case series study included all patients with NSCLC admitted to the Military Medical Academy in Belgrade in the period 2010-2015. A total number of selected patients was 85 (27 females and 58 males). Results. Out of 41 patients with squamous cell carcinoma, 19.5% deceased. On the other hand, in the group of patients with adenocarcinoma, 43.2% Ključne reči: pluća, nesitnoćelijski karcinom; adenokarcinom; karcinom skvamoznih ćelija; preživljavanje; recidiv.
We presented a rare clinical entity with typical clinical features and clinical and radiological course of the disease, in order to improve differential diagnostic approach to patients with bilateral lung infiltrations. In patients with pulmonary alveolar proteinosis timely diagnosis and adequate treatment can improve a prognosis.
Background/Aim. Bronchial asthma is a disease that is characterized by the variability of the clinical picture, physical and functional status and the existence of bronchial hypersensitivity and hyperreactivity with varying degrees. Bronchial responsiveness and sensitivity are tested in patients with clinically suspected existence of asthma and normal spirometry test. The aim of the study was to analyze the patients with atopic asthma and study test results of skin sensitization to inhaled allergens, nonspecific bronchial hyperreactivity and specific hyperreactivity estimated by bronchial provocation tests with inhalant allergens. Methods. The prospective study at the Pulmonology Clinic of the Military Medical Academy in Belgrade Serbia, during 2014, included 70 male subjects aged 18?30 years, who had perennial asthma symptoms. All subjects were nonsmokers, with normal spirometry findings, with normal radiological chest findings and with no symptoms of respiratory infection over the past two months. All respondents were tested with skin prick tests with inhalant allergens and nonspecific bronchial provocation test with histamine. On the basis of histamine test, subjects were divided into two groups: the group I, in which there was a slight degree of hypersensitivity [provocation concentration of histamine causing a 20% fall in forced expiratory volume ? PC20 = 6.09 ? 1.1 mg/mL], and the group II with negative histamine test (PC20 = 14.58 ? 6.34 mg/mL). Specific bronchial provocation test was performed in all patients, and the selection of the allergens was carried out based on the results of testing of skin hypersensitivity. Results. Results of skin sensitization show the highest incidence of mites Dermatophagoides pterronissinus (83.3% group I and 85.0% group II) followed by grass pollen (53.3% group I and 52.0% group II), and house dust (33.3% group I and 50.0% group II). There were no statistically significant differences in allergens between groups (p > 0.05). In both groups, spirometry findings were within normal values [forced vital capacity ? FVC and forced expiratory volume 1 ? FEV1 > 80% predictive value], but statistically significant difference was found in FEV1 between groups (p < 0.05). Specific bronchial provocation tests with solutions of inhaled allergens in both groups caused a significant decline in FEV1 (? 20%) in all patients individually. No statistically significant differences were found neither between groups, nor between individual allergens (average decline in FEV1: Group I 32.9 ? 2.4% and group II 31.5 ? 2.2%). Conclusion. There is no relationship between the degree of specific and non-specific bronchial hyperreactivity in patients with allergic asthma.
Pseudomesotheliomataus carcinoma of the lungs can be a diagnostic problem. Its diagnosis is based on recognition of histopathological characteristics which enable its discernment from the epithelial variant of malignant pleural mesothelioma.
Cholesterol and carcinoembryonic antigen (CEA) levels in pleural effusion and sera, were measured in 199 patients with pleural effusions of various origins. Malignant cause was found in 93, and nonmalignant in 106 patients. Mean cholesterol level in sera of patient with malignant disease was 5.0 +/- 0.93 mmol/L, and in nonmalignant group 4.34 +/- 1.32 mmol/L. The difference was not statistically significant. Mean cholesterol level in nonmalignant pleural effusions was higher thAn those in malignant (2.51 +/- 1.23 mmol/L; and 2.28 +/- 1.06 mmol/L), but the difference was also not significant. Average pleural fluid/serum cholesterol ratio (Holl/S) in nonmalignant group was 0.61 +/- 0.32 and in malignant group 0.46 +/- 0.22. The difference between those mean values was significant. Higher ratio, at the cut off value of 0.5 was found in 79/106 and in 25/93 malignant patients. Calculated sensitivity was 75%, specificity 73%, positive predictive value 76%, negative predictive value 65% and accuracy 69%. Significant negative correlation between Holi/S and pleural fluid CEA was found (p < 0.05). It was assumed that pleural fluid/serum cholesterol ratio lower than 0.5 could be of great benefit, as an additional test in the differentiation of malignant from benign pleural effusion.
