Comparative Study Clinical TrialFDG-PET imaging for lymph node staging and pathologic tumor response after neoadjuvant treatment of non-small cell lung cancer.
A number of studies have demonstrated that 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) is effective for staging of lung cancer. However, the efficacy of FDG-PET for staging lung cancer after neoadjuvant treatment is still controversial. This study compared FDG-PET and computed tomography (CT) for lung cancer staging, and evaluated the ability of the two methods to predict the pathologic response of the primary tumor to neoadjuvant treatment. ⋯ FDG-PET did not appear to offer any advantages over CT for lymph node staging or for predicting the pathologic response after neoadjuvant treatment of non-small cell lung cancer.

Comparative Study Controlled Clinical TrialMeasurement of cerebral-oxygenation status when commencing cardiopulmonary bypass in pediatric open-heart surgery.
We hypothesize that there is a difference in the cerebral-oxygenation status between cyanotic and non-cyanotic congenital heart disease when commencing a crystalloid-primed cardiopulmonary bypass (CPB). We tested this hypothesis by using near-infrared spectroscopy (NIRS). ⋯ NIRS revealed that the cerebral-oxygenated hemoglobin could be maintained at a similar level at the beginning of CPB in both groups. However, it showed a different distribution of cerebral-deoxygenated and total hemoglobin between the groups. An inadequate cerebral-oxygenation status may occur in the early phase of CPB in patients with cyanotic congenital heart diseases.

Case ReportsA case complicated with Horner's syndrome after off-pump coronary artery bypass.
In the present report, a case complicated with Horner's syndrome after off-pump coronary artery bypass (OPCAB) was presented. This case showed ptosis and miosis in the left eye promptly after OPCAB. No abnormal neurological findings other than Horner's syndrome were observed in postoperative examinations including head magnetic resonance imaging (MRI), and this case was thought to have Horner's syndrome as a complication after cardiac surgery through median sternotomy.

Case ReportsKissing pleural metastases from metastatic osteosarcoma of the lung.
Two patients with osteosarcoma lung metastases of which migrated to the parietal pleura due to contact are reported. The first patient was a 16-year-old male who had a pleural metastasis in the diaphragm within an area in contact with a single lung metastasis. Both of the tumors were resected, followed by systemic chemotherapy. ⋯ The patient is alive without recurrence 84 months after the first resection of the metastases. The second patient was an 11-year-old female with a pleural metastasis of osteosarcoma which was within an area in contact with a single lung metastasis, which had been resected 4 months before. We concluded (1) that a lung metastasis of osteosarcoma occasionally metastasizes to the pleura due to contact; and (2) that because this kissing metastases of osteosarcoma could be cured by a complete resection, the intrathoracic cavity should be thoroughly observed.

Case ReportsIsthmus of a horseshoe kidney overlying a ruptured abdominal aortic aneurysm: a case report.
Horseshoe kidney is a rare congenital anomaly showing various degrees of fusion and accessory blood supply. Coexistence of horseshoe kidney and aortic aneurysm therefore presents a technical challenge to vascular surgeons. ⋯ The aneurysm was exposed via a transperitoneal approach, and grafting was performed successfully together with division of the isthmus of the horseshoe kidney. Renal function showed no impairment postoperatively.
