RESUMEN
BACKGROUND: Optimal pain management after video-assisted thoracic surgery (VATS) remains an open issue. We prospectively studied the analgesic effect of intercostal analgegia (ICA) by comparison with epidural analgesia. METHODS: Twenty-two patients undergoing VATS procedures were randomly divided into ICA (n = 8) or epidural (n = 14) group. Postoperatively 2 ml x hr(-1) of 0.2% ropivacaine was delivered continuously through intercostal or epidural catheter. Moreover, each group received the equal dose of fentanyl (0.25 x µg(-1). kg(-1) x hr(-1)) intravenously or epidurally. When no pain relief was achieved, iv fentanyl was given as a rescue. Requirement of additional fentanyl and pain score using a visual analogue scale (VAS) were documented for 19 hours. RESULTS: The mean pain scores at rest, mobilization and with coghing were slightly higher in the ICA group. Total additional dose of iv fentanyl was significantly different between the groups (ICA 147 ± 41 vs Epidural 39 ± 15 µg; P = 0.015). Pain scores and fentanyl requirements spread over the lower range. The mean of VAS in ICA group was less than 5 even at coughing, suggesting clinically irrelevant. CONCLUSIONS: In patients with coagulopathy, multimodal approach using intercostal analgesia supplemented by intravenous patient-controlled analgesia may be an alternative to epidural analgesia for postoperative pain management.

We report a new type of secondary malignant giant cell tumor of bone, the malignancy of which was assigned to a carcinosarcoma, i.e., osteosarcoma and squamous cell carcinoma. It occurred 25 years after curettage and bone graft surgery under the diagnosis of giant cell tumor of the right distal femur. Although secondary malignant giant cell tumor is known as a sarcoma arising at the site of a previously diagnosed giant cell tumor, this case should be regarded as a new type of secondary malignant giant cell tumor of bone.

BACKGROUND AND AIMS: This study examined the impact of CD14++CD16+ monocytes on coronary plaque vulnerability, as assessed by optical coherence tomography (OCT), and investigated their association with daily glucose fluctuation. Although increased CD14++CD16+ monocyte levels have been reported to increase cardiovascular events, their impact on coronary plaque vulnerability in coronary artery disease (CAD) patients with or without diabetes mellitus (DM) remains unclear. METHODS: This prospective observational study included 50 consecutive patients with CAD, receiving lipid-lowering therapy and undergoing coronary angiography and OCT. Patients were divided into 3 tertiles according to the CD14++CD16+ monocyte percentages assessed by flow cytometry. Standard OCT parameters were assessed for 97 angiographically intermediate lesions (diameter stenosis: 30-70%). Daily glucose fluctuation was analyzed by measuring the mean amplitude of glycemic excursion (MAGE). RESULTS: CD14++CD16+ monocytes negatively correlated with fibrous cap thickness (râ¯=â¯-0.508, pâ¯<â¯0.01). The presence of thin-cap fibroatheroma (TCFA) was increased stepwise according to the tertile of CD14++CD16+ monocytes (0 [tertile 1] vs. 5 [tertile 2] vs. 10 [tertile 3], pâ¯<â¯0.01). CD14++CD16+ monocytes were a significant determinant of TCFA (OR 1.279, pâ¯=â¯0.001). In non-DM patients, a significant relationship was found between CD14++CD16+ monocytes and MAGE (râ¯=â¯0.477, pâ¯=â¯0.018). CONCLUSIONS: CD14++CD16+ monocytes were associated with coronary plaque vulnerability in CAD patients with well-regulated lipid levels both in DM and non-DM patients. Cross-talk between glucose fluctuation and CD14++CD16+ monocytes may enhance plaque vulnerability, particularly in non-DM patients. CD14++CD16+ monocytes could be a possible therapeutic target for coronary plaque stabilization.

RESUMEN
BACKGROUND: The standard treatment for patients with stage IV non-small cell lung cancer (NSCLC) is systemic chemotherapy. However, certain patients, such as those with oligometastasis or M1a disease undergo resection of the primary lesion. METHODS: We conducted a retrospective review of the records of 1,471 consecutive patients with NSCLC who underwent resection of the primary lesion for between June 2005 and May 2016. The present study included 38 patients with stage IV NSCLC who underwent complete resection of the primary lesion as first-line treatment. RESULTS: The median follow-up duration for the 38 patients (27 men) was 17.7 months (range, 1-82.3 months). The T factors were T1/T2/T3/T4 in 4/16/12/6 patients, respectively. The N factors were N0/N1/N2/N3 in 16/8/12/2 patients, respectively. The M factors were M1a/M1b/M1c in 19/13/6 patients, respectively. Of the 19 M1a patients, 11 were classified as cM0. We introduced the novel classification M-better/M-worse. M-better includes cM0 patients and M1b and M1c patients in whom all lesions have been locally controlled. M-worse includes cM1a patients and M1b and M1c patients in whom lesions cannot be locally controlled. The new M-better/M-worse statuses were 24/14 patients, respectively. The histology of NSCLC was adenocarcinoma/squamous cell carcinoma/others in 30/5/3 patients, respectively. The 5-year overall survival rate was 29%, and the median survival time was 725 days. Squamous cell carcinoma and M-worse were significant factors predicting poor outcomes (P=0.0017, P=0.0007, respectively). CONCLUSIONS: Even for stage IV NSCLC patients, resection of the primary lesion may be beneficial, especially for those with M-better status and those not diagnosed with squamous-cell carcinoma (SCC).
RESUMEN
We herein present the pathological findings of a bulla covered using an absorbable polyglycolic acid sheet applied with fibrin glue. These findings indicated that the membrane of the bulla was reinforced. Covering the bulla with an absorbable polyglycolic acid sheet (Neoveil, Gunze Ltd, Kyoto, Japan) and applying fibrin glue was effective to prevent the recurrence of the pneumothorax. Moreover, this report is the first case report showing the pathological findings of a bulla which was covered with an absorbable polyglycolic acid sheet and fibrin glue.

Pulmonary ground-glass opacity (GGO) nodules, which do not grow remarkably, are often observed without treatment. Lung tumors coexisting with inflammation and infection are difficult to diagnose. In this paper, we describe a very rare case of a pulmonary mixed GGO nodule with pleural dissemination. In 67-year-old female, chest computed tomography (CT) showed a mixed GGO nodule that had not grown remarkably in the right lung. For 6 years, the mixed GGO had been treated as nontuberculous mycobacterial infection. She was referred to our department for further investigation of the mixed GGO. We suspected lung cancer and performed lung segmentectomy. The tissue showed pleural dissemination. Coexisting nontuberculous mycobacteria (NTM) delayed the clinical diagnosis. Peripheral lung nodules should be resected or diagnosed as soon as possible, despite manifesting as a slow growth.
RESUMEN
BACKGROUND: This study analysed the humoral immune response in asbestos exposed lung cancer patients to identify new surrogate markers of the carcinogenic risk in populations exposed to asbestos. METHODS AND RESULTS: A serological analysis identified five distinct antigens reactive with IgG derived from a lung cancer patient with high asbestos exposure. In one of the isolated antigens, quantitative RT-PCR indicated that annexin A2 (AnxA2) was overexpressed in lung cancer tissues and normal lung from patients with high asbestos exposure. Antibody against AnxA2 was detected in 9/15 (60%) of lung cancer patients with high asbestos exposure; however, in only 1/12 (8%) of lung cancer patients with low asbestos exposure. AnxA2 was also overexpressed in malignant mesothelioma cells, and the antibody was also positive in 8/15 (53%) of patients with malignant mesothelioma. CONCLUSION: The antibody titer against AnxA2 may be a potentially useful new diagnostic surrogate marker for asbestos-related lung cancer and malignant mesothelioma.
