Traumatic pulmonary pseudocysts are pulmonary lesions that occur after either blunt or penetrating trauma and tend to be overlooked. Most of these lesions are self-limiting, benign lesion.

Selvi, A. Kant, S. Arslan, M. Ozgel. Background: Residual pleural thickening (RPT) still occurs in most patients with tuberculosis pleurisy despite advances in the treatment of tuberculosis. The aim of this study was to evaluate the significance of RPT in tuberculosis pleurisy with the patients clinical findings, biochemical and microbiological properties of pleural effusion and with the total adenosine deaminase (ADA) and isoenzymes levels. Methods: 121 tuberculosis pleurisy patients were evaluated retrospectively. According to posteroanterior chest x-rays, the 63 (52%) cases with the thickness 2 mm or more in lower lateral hemithorax were grouped as I and the 58 (48%) cases without pleural thickness were grouped as II. The amount of pleural effusion was classified into small, medium or massive according to their chest x-rays. In both groups; sex, age, symptoms score, bacteriological and biochemical tests and ADA levels were recorded. Results: 81 (67%) male and 40 (33%) female, overall 121 patients were enrolled into the study. RPT was found higher in males (p=0.014) and the increase ran parallel with the amount of cigarette smoking (p=0.014). RPT was found to be lower in small effusions (p=0.001). The group with RPT, the serum albumin was found lower (p=0.002), pleural fluid total protein (p=0.047) and the ratio of pleural fluid protein to serum protein (p=0.002) were found higher. In group I, total ADA: 69.5±38.9 IU/L and ADA2: 41.3±31.6 IU/L were higher than the cases without RPT (p=0.032, p=0.017, respectively). Conclusions: We suggest that the immunological mechanisms are effective in the development of pleural thickening.

StreszczenieW pracy przedstawiono przypadek 65-letniej kobiety z nasileniem duszności i kołatania serca od 2 miesięcy. W badaniu echokardiograficznym stwierdzono obecność masy w śród-piersiu o wymiarach 61 × 47 mm uciskającej lewy przedsionek. Tomografia komputerowa (computed tomography -CT) i rezonans magnetyczny (magnetic resonance imaging -MRI) wykazały obecność dobrze zorganizowanej masy z hipotensyjnym ograniczeniem, umiejscowionej pomiędzy lewym przedsionkiem a aortą zstępującą i przylegającej do przełyku. Opisano bardzo rzadki przypadek ucisku lewego przedsionka przez guz śródpiersia, którym była schwannoma. Słowa kluczowe: masa w śródpiersiu, schwannoma. AbstractA 65-year-old woman presented with worsening of respiratory discomfort and palpitations for two months. Echocardiography revealed a mediastinal mass compressing the left atrium which measured 61 × 47 mm. Computed tomography (CT) and magnetic resonance imaging (MRI) showed a well-circumscribed mass with hypointense septation located between the left atrium and descending aorta and adjacent to the esophagus. We report a very rare case of the left atrium compressing a mediastinal tumor which was a schwannoma.

BackgroundCOPD is preventable and treatable and is characterized by completely nonreversible airflow obstruction. In this study, we aimed to investigate the effect of long-term oxygen therapy on patients with stage 4 COPD who were followed up and treated at the polyclinic or clinic service. We evaluated the effects of oxygen therapy on energy metabolism and physical activity in patients with COPD.MethodsNineteen patients with COPD (16 male/3 female), treated with oxygen therapy for the first time, were included in this study. Analysis of arterial blood gases and pulmonary function test was performed. Metabolic Holter device (SenseWear® Armband) was placed pre- and post-oxygen therapy on the patients’ arm for at least 3 days. This device captures Holter data in a digitized electronic system, and the daily average value was calculated from the data.ResultsPost-oxygen treatment showed a significant increase in energy expenditure by patients with COPD (pretreatment, 1,497±596 joule; posttreatment, 2,977±5,985 joule; P=0.044). Moreover, number of steps during walking (pretreatment, 2,056±256; posttreatment, 2,120±195; P=0.03), resting (pretreatment, 6.36±3.31 hours; posttreatment, 3.47±2.19 hours; P<0.03), and sleeping (pretreatment, 4.23±2.13 hours; posttreatment, 2.33±1.42 hours; P<0.00) showed significant differences. Increased daily energy expenditure in patients with respiratory failure was detected with long-term oxygen therapy. In addition, the immobility of patients decreased and duration of physical activity increased in patients with COPD.ConclusionIn this study, positive effects of long-term oxygen therapy have been demonstrated with respect to energy metabolism and physical activity of patients with COPD. Thus, we recommend that medication adherence and long-term oxygen therapy should begin early in patients with COPD.
