A novel noninvasive magnetic resonance imaging (MRI) method was developed to determine in vivo blood oxygen saturation and its changes during motor cortex activation in small cerebral veins. Specifically, based on susceptibility measurements in the resting states, pial veins were found to have a mean oxygen saturation of Yrest=0.544+/-0.029 averaged over 14(More)
We report a case showing delayed hemothorax superimposed on extrapleural hematoma after blunt chest injury. The patient was a 56-year-old man with a medical history of alcoholic hepatopathy who presented with a chief complaint of dyspnea on exertion. One month prior to presentation, he had sustained a fall that had resulted in left simple rib fracture. A(More)
We present a primary spontaneous pneumothorax involving a possible diagnostic and surgical pitfall. A 25-year-old man with a previously identified azygos lobe was admitted to our hospital because of right primary spontaneous pneumothorax. A preoperative chest X-ray at the onset of the pneumothorax as well as after resolution by tube drainage showed an(More)
Lung cancer is a leading cause of cancer mortality worldwide and patients occasionally develop local recurrence or distant metastasis soon after curative resection. Reports of new therapeutic strategies for lung squamous cell carcinoma (SqCC) are extremely rare, while selective anticancer therapy has been reported(More)
We report a case of descending necrotizing mediastinitis (DNM). DNM is a serious infection, and preventing death requires early diagnosis and draining of the infection focus. An 84-year-old man was admitted to our hospital complaining of a swollen neck and pain when swallowing. He had had a tooth extracted at a neighboring dental clinic 2 days previously.(More)
CASE A 41-year-old man survived deep pulmonary and hepatic lacerations by treatment with fluid resuscitation, blood transfusion, thoracotomy, and transcatheter hepatic artery embolization. The patient was transferred to our hospital 46 minutes after his motorbike struck a station wagon from behind. Hemorrhagic shock with systolic blood pressure of 68 mmHg(More)
We performed a video-assisted thoracoscopic segmental resection without doing a mini-thoracotomy in two patients (one octogenarian and one with poor lung function) with early stage (T1-2N0) lung cancer located at the lung hilum who required preservation of their cardiopulmonary function. After 2 years of follow-up, both patients are alive without(More)
Liposome-encapsulated hemoglobin (LEH) has been reported to accelerate wound healing in the stomach and skin in an experimental setting. LEH was tested in bronchial anastomotic healing after radiation and pneumonectomy in the rat. Sprague-Dawley rats (n = 61) received preoperative radiation (20 Gy) to the chest and underwent left pneumonectomy with(More)
Hepatocellular carcinoma occasionally metastasizes to extrahepatic organs, rarely to the mediastinal lymph nodes. We present the case of a 64-year-old man who presented with nodules in the upper and right lower lobes of the lung 4 years after undergoing resection of a hepatocellular carcinoma. We performed wedge resection of both lesions. Pathological(More)
The predictors of oxygen desaturation during exercise in patients submitted to major pulmonary resection for lung cancer are to be determined. We analyzed retrospectively the relation between the oxygen saturation by pulse oxymetry (Spo2) during exercise and the predictions of postoperative pulmonary function. A hundred twenty-two patients with lung cancer(More)
