Insertion of two chest tubes is not more effective than the insertion of a single chest tube after pulmonary lobectomy. Moreover, using a single tube is in fact more effective than using two tubes in that it causes less postoperative pain and less pleural fluid loss.

The open decortication for chronic pleural empyaema significantly increases FEV(1) and FVC. Due to the re-expansion of the lung and enlargement of the intercostal spaces, the chest wall deformity also improves considerably after the operation.

Expansion of the lung is necessary for successful pleurodesis therapy in patients with malignant pleural effusion (MPE). However, this is often impossible in multiloculated MPEs. The aim of this study was to investigate the effect of the fibrinolytic agent, streptokinase, on pleurodesis therapy used in the management of multiloculated MPE. Forty patients with multiloculated MPEs were randomly assigned to two groups: fibrinolytic and control. In the fibrinolytic group, 250,000 IU of streptokinase in 50 ml saline was applied into the pleural space at 24-36-48-60 h after opening a tube thoracostomy. In the control group, the same procedure was carried out using only 50 ml saline solution. Both groups were compared based on the following: (1) volume of pleural drainage at 24-48, 48-72, and 24-72 h, (2) chest computer tomography images before and after therapy, (3) dyspnea symptoms after therapy, and (4) recurrence rate. The mean drainage volumes for the fibrinolytic and control groups were 493 and 248 cc at 24-48 h, 446 and 198 cc at 48-72 h, and 939 and 446 cc at 24-72 h (P < 0.001). Comparison of the two groups by computer tomography revealed that 17 patients (85 %) in the fibrinolytic group had greater than 40 % improvement, whereas only 7 patients (35 %) in the control group had the same degree of improvement (P = 0.001). The dyspnea symptoms disappeared in 90 % of the patients in the fibrinolytic group and in 55 % of the patients in the control group (P = 0.03). Recurrence rate was 11 % in fibrinolytic group and 45 % in control group (P = 0.07). Streptokinase is a reliable treatment option in obtaining effective pleural drainage and increasing lung expansion in patients with multiloculated MPE.

The purpose of this study was to explore the accuracy of (18)F-fluorodeoxyglucose (FDG)-positron emission tomography/computed tomography (PET/CT) in the assessment of mediastinal lymph node in coal workers who had non-small cell lung cancer. We retrospectively reviewed 42 retired coal workers who had lung cancer without distant metastasis, between May 2007 and May 2010. Regarding the mediastinal lymph nodes, when the standard uptake value was greater than 2.5, it was considered "malignancy positive." After histological examination of the mediastinal lymph nodes, anthracotic and metastatic ones were detected. The results of PET/CT were analyzed to determine its accuracy. Of these 42 patients, PET/CT detected 47 positive mediastinal lymph nodes in 24 patients with a mean SUV maximum of 6.2 (2.6-13.8). One hundred and thirty-one mediastinal lymph node foci were dissected. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of FDG-PET/CT in detecting nodal metastases were 84% (16/19), 65% (15/23), 66% (16/24), 83% (15/18), and 74% (31/42) on a per-patient basis, respectively. Mediastinal node staging with FDG-PET/CT in coal workers is insufficient due to the high false-positive rates due to the presence of pneumoconiosis. In these patients, an invasive technique such as mediastinoscopy seems mandatory for confirmation of ipsilateral or contralateral mediastinal lymph node metastasis.

BackgroundThe goal of our study is to evaluate the effects of antioxidant vitamins (vitamin C and E), Coenzyme Q10 (CoQ10) and dexamethasone (Dxm) in experimental rat models with pulmonary contusion (PC).MethodsRats were randomly divided into six groups. Except for the control, all subgroups had a moderate pulmonary contusion. Animals in the group I and group II received intraperitoneal saline, group III received 10mg.kg-1 CoQ10 group IV received 100mg.kg-1 vitamin C, group V received 150mg.kg-1 vitamin E, and group VI received 10mg.kg-1 Dxm. Blood gas analysis, serum nitric oxide (NO) and malondialdehyde (MDA) levels as well as superoxide dismutase (SOD) activity assays, bronchoalveolar lavage (BAL) fluid and histopathological examination were performed.ResultsAdministration of CoQ10 resulted in a significant increase in PaO2 values compared with the group I (p = 0.004). Levels of plasma MDA in group II were significantly higher than those in the group I (p = 0.01). Early administration of vitamin C, CoQ10, and Dxm significantly decreased the levels of MDA (p = 0.01). Lung contusion due to blunt trauma significantly decreased SOD activities in rat lung tissue compared with group I (p = 0.01). SOD levels were significantly elevated in animals treated with CoQ10, Vitamin E, or Dxm compared with group II (p = 0.01).ConclusionsIn our study, CoQ10, vitamin C, vitamin E and Dxm had a protective effect on the biochemical and histopathological outcome of PC after experimental blunt thorax trauma.

Artificial prophylactic intraoperative pneumoperitoneum is a simple and safe procedure that decreases the postoperative amount of fluid drainage, residual pleural space, duration of chest tube drainage, and hospital stay.

The purpose of this study was to investigate the effects of ghrelin on inflammatory response and tissue damage following trauma-induced acute lung injury. Thirty male wistar albino rats (300-400 g) were randomly assigned into three groups: control group (n = 6), lung contusion plus saline (saline-treated, n = 12), and lung contusion plus ghrelin (ghrelin-treated, n = 12). Saline- or ghrelin-treated traumatic rats were sacrificed at two time points (24 and 72 hours) after lung contusion. Blood was collected for the analysis of serum adenosine deaminase (ADA). Tissue transforming growth factor-beta 1 (TGF-β1) and matrix metalloproteinase-2 (MMP-2) levels were measured by enzyme-linked immunosorbent assay and histopathological examination was performed on the lung tissue samples. Our results indicated that ghrelin significantly reduced morphologic damages. Serum ADA activities were significantly decreased after lung contusion and this decline started early with ghrelin treatment. TGF-β1 and MMP-2 levels in lung tissue were elevated at 72 hours after lung contusion and treatment with ghrelin significantly increased TGF-β1 level and reduced MMP-2 level. In conclusion, our study demonstrates that acute lung injury initiated proinflammatory responses and ghrelin administration showed an anti-inflammatory effect in lung contusion.

Chylothorax is characterized by accumalation of milky fluid called chyle into the plural space. Most common causes of cyhlothorax are trauma or surgery of thoracic duct and malignancies. Among the malignancies lymphoma is responsible approximately 70% of cyhlothorax but other lymphocytic tumors including chronic lymphocytic leukemia (CLL) is rarely reported. A 71 years old man with known CLL, presented with dispnea and pleural effusion and diagnosed cyhlothorax due to leukemic infiltration that confirmed by immuno flow cytometric analyse.
