We present herein the unusual case of a 75-year-old woman in whom an esophageal cyst was preoperatively identified with the aid of transesophageal ultrasonography. She underwent successful extirpation and has remained well since her discharge from hospital. The transesophageal ultrasonogram was shown to be a powerful diagnostic tool for the identification(More)
The highly radioresistant Rubrobacter radiotolerans, contains red pigments. Since the pigments could not be extracted by usual methods, a new method was developed in which the pigments were extracted with organic solvents after addition of 10 N KOH to the intact cells, followed by neutralization. These pigments were also extracted after treatment with(More)
The whitefly, Aleurocanthus camelliae Kanmiya and Kasai (Hemiptera: Aleyrodidae), is an invasive species in Japan that was first discovered in 2004 on tea in Kyoto. Soon after its arrival epizootics of an entomopathogenic fungus were observed in populations of the whitefly in many tea-growing regions. Here we identify this fungus as Paecilomyces cinnamomeus(More)
A 41-year-old man was diagnosed as having primary parotid carcinoma on the right side. After radical parotidectomy, radiation therapy and systemic chemotherapy, the primary parotid carcinoma was completely remitted. Two years later, right abducens nerve palsy and Horner syndrome appeared. Neuroimaging demonstrated a gadolinium-enhanced lesion in the(More)
PURPOSE To evaluate, in Japan Clinical Oncology Group study 0403, the safety and efficacy of stereotactic body radiation therapy (SBRT) in patients with T1N0M0 non-small cell lung cancer (NSCLC). METHODS AND MATERIALS Eligibility criteria included histologically or cytologically proven NSCLC, clinical T1N0M0. Prescribed dose was 48 Gy at the isocenter in(More)
CONCLUSION A long-term study was carried out on 57 patients treated with radiation alone who had T2N0M0 squamous cell carcinoma of the glottic larynx. The response and survival rates were satisfactory, but the complete response (CR) and the larynx preservation rates showed a need for improvement. Thirty-four patients underwent salvage operations and a safe(More)
We report herein the case of a 61-year-old man with myelodysplastic syndrome causing pancytopenia who underwent successful coronary artery bypass grafting (CABG). Preoperatively, his hemoglobin (Hb) value was 10.4 g/dl while receiving transfusions of 1 or 2 units of red blood cells (RBC) every 2 weeks, his white blood cell (WBC) count was 8200/μl with(More)
CONCLUSION Patients who received concurrent chemoradiation therapy with carboplatin were followed up on a long-term basis. In 25 patients treated with carboplatin at an AUC of 2.0 mg/ml, the complete response (CR), 10-year survival, and 10-year larynx preservation rates were 96.0%, 91.1%, and 75.2%, respectively, and the safety margin for partial(More)
OBJECTIVE We discuss the clinical aspects related to mechanical valve dysfunction based upon 20 years' experience of our cases. METHODS Between January 1982 and December 2001, 21 patients underwent surgical interventions because of mechanical valve dysfunction. Thirteen men and 8 women (mean age 47 +/- 20, range 3-75 years-old), were included. RESULTS(More)
BACKGROUND We have previously reported mid-term results of a study, which ended in January 2000, on the Bicarbon valve. The study concluded that the valve showed excellent clinical results, associated with a low incidence of valve-related complications. In the present study, the same patients were prospectively followed for an additional 5 years. METHODS(More)
