[A case of primary intrapulmonary thymoma: its entity and the problem of lymph node dissection].

Primary intrapulmonary thymomas are defined as primary thymomas arising in an intrapulmonary location without an associated mediastinal component, and they are very rare. A total of 20 cases have been reported only sporadically in the English literature since 1951. We reported the case of 41-year-old woman who had a 3.

Determining factors of mortality in the elderly with hip fractures.

We conducted a retrospective study of the influence of various factors on the mortality of 114 patients with hip fractures. The mortality rate one year after surgery was 18%, which was 2.5 times larger than that of the general population.

[Current status of cancer pain control in home hospice care--assessment by family members].

To improve the quality of life of terminally ill cancer patients, we care for them in the home whenever possible, making use of home parenteral nutrition (HPN) and continuous intravenous infusion of morphine. The purpose of this study was to assess the current status of and problems associated with our home hospice care program, with emphasis placed on the effectiveness of cancer pain control as viewed by the family of the patient. A questionnaire was sent to six families of patients who died at home.

[Continuous injection therapy of morphine solution for terminally-ill patients at home].

We surveyed 21 terminally-ill patients with cancer pain who received continuous injection therapy of morphine at home in the three years from 1995 to 1997. The period of home therapy was 179.3 +/- 257.

Comparison of patient-controlled epidural analgesia with and without background infusion after gastrectomy.

Unlabelled: To assess the analgesic efficacy and side effects of concurrent infusion in patient-controlled epidural analgesia (PCEA) after upper abdominal surgery, 40 patients undergoing elective gastrectomy under general anesthesia were allocated to two groups in this randomized, double-blind study: one received a 2.5-mL incremental bolus in a solution of 0.2% bupivacaine and 10 microg/mL fentanyl, and the other received the same bolus dose plus a 2.

[The necessity of mediastinal lymph node dissection for yolk sac tumor of the anterior mediastinum].

Combined treatment with preoperative chemotherapy and surgical resection is the universally accepted effective treatment of mediastinal yolk sac tumors. However, a problem on the need and efficacy of lymph node dissection in mediastinal yolk sac tumors has been not enough discussed in the past. We reported a case of mediastinal yolk sac tumor with nodal metastasis.

[Small cell lung cancer with acute monocytic leukemia after combined chemotherapy including etoposide].

Small cell lung cancer (stage IIIB) developed in a 61-year-old woman. She was treated with chemotherapy in which the cumulative dose of carboplatin was 662 mg/m2 and that of etoposide was 2,000 mg/ m2, and with concurrent irradiation in which the total dose of X-rays was 44.8 Gy.

[Permanent pacemaker implantation in patients aged 80 years or older].

Forty-five patients aged 80 years or older at the time of initial permanent pacemaker implantation were followed for 3 to 132 months (mean 40.8). There were 27 males and 18 females.

An autopsy case of intravascular malignant lymphoma presenting with intracranial B-cell type malignant lymphoma.

This report concerns a 79-year-old man with intravascular malignant lymphoma who was admitted to our hospital for slight right side hemiparesis. Radiological examinations showed a mass in the left parietal lobe, and a brain biopsy revealed a B-cell type malignant lymphoma. The tumor could not be detected on magnetic resonance images following focal radiotherapy, but the patient died of acute progressive pneumonia about 3 months after the onset of symptoms.

[Repeated administration of protamine attenuates protamine-induced systemic hypotension].

Protamine may act on endothelial cell receptors to stimulate the production of nitric oxide, which would promote vasodilation. If so, the repeated administration of protamine may attenuate protamine-induced systemic hypotension. To confirm this hypothesis, we examined whether repeated administration of protamine attenuates protamine-induced systemic hypotension in rats.

[A case of coronary artery bypass grafting using patch mounted graft technique for aortitis syndrome with left coronary ostial stenosis].

Coronary artery bypass grafting (CABG) was performed on a 36-year-old female for treatment of aortitis syndrome with left coronary ostial stenosis. The left anterior descending artery was anastomosed with the left internal thoracic artery. The circumflex artery was anastomosed with the saphenous vein.

[Graft replacement for repair of coarctation of the aorta in adults: a case report].

A 42-year-old woman admitted to the hospital because of systolic murmur and upper body hypertension. Cardiac catheterization revealed tubular coarctation of the aorta and 60 mmHg pressure gradient across the coarctation. The graft replacement for repair of coarctation of the aorta was performed under femoro-femoral cardiopulmonary bypass.

[Primary carcinosarcoma of TE lung--a report of two cases].

Carcinosarcoma is a rare lung tumor and accounts for less than 0.3% of primary lung malignancies. Since the first description by Kika in 1908, only 36 cases with this kind of tumor have been appeared in the Japanese literatures by 1993.

[An elderly patient with traumatic acute subdural hematoma who "talked and deteriorated"].

A 62-year-old man was transferred to our hospital 20 min after a motor vehicle accident. The CT scan on admission revealed mixed density area of acute subdural hematoma, but he was asymptomatic on physical examination. Course observation without brain edema therapy resulted in severe disturbance of consciousness 2 hours after the traffic accident.

[The effect of continuous epidural infusion of combination of buprenorphine and bupivacaine for postoperative pain relief using a portable 0.5 ml.h-1 type infuser with patient control module].

Using a portable 0.5 ml.h-1 type infuser with Patient Control Module (Baxter infuser BB+ PCM), we compared patients receiving continuous epidural infusion with patients using self controlled analgesia system for postoperative analgesia after upper abdominal surgery.

[Airway management in complete transection of the trachea due to traffic accident].

Oro-tracheal intubation to prevent the development of subcutaneous emphysema after blunt trauma by a traffic accident resulted in progressively worsening dyspnea because of complete transection of the trachea. Emergent tracheal reconstruction was required for life-saving. In order to secure a safe and effective airway in such a patient, we should diagnose accurately and select the methods of securing the airway earlier in the post-traumatic period.

[Chondrosarcoma of the skull base associated with fatal intratumoral hemorrhage : report of an autopsy case and review of the literature].

We report a case of intracranial chondrosarcoma of the skull base with fatal intra- and peritumoral hemorrhage. A 75-year-old woman complained of right blepharoptosis and diplopia in 1989. An initial diagnosis of Tolosa-Hunt syndrome was made, and the patient was treated with steroid hormone therapy at a local hospital.

[Transesophageal echocardiographic evaluation of the effect of isoflurane on cardiac systolic and diastolic function].

In this study, we used transesophageal echocardiography to investigate the effect of isoflurane (0.0, 0.3, 0.

[Home therapy approach in cancer patients--pain control (case 3-1)].

We present a case study of 34 years old female patient who had intractable pain in terminal stage of lung cancer. She complained severe persistent shooting pain in left lateral pectoral region, where was a wound of thoracotomy. She was given several analgesics orally in order of their efficacy, but could not get sufficient pain relief.

[The effect of subcutaneous administration of buprenorphine with patient controlled analgesia system for post-operative pain relief].

We conducted a study comparing patients receiving continuous subcutaneous administration of analgesia with self controlled analgesia system (CSAA group) with those receiving continuous epidural infusion (Epi group) for postoperative analgesia after abdominal surgery. Fourteen patients were randomized into two groups: CSAA group (n = 7) received 20 micrograms.h-1 of buprenorphine (Bu) subcutaneously with additional 20 micrograms of Bu using Baxter infusor BB+PCA; Epg group (n = 7) received continuous epidural infusion of 0.

[Mitral valve aneurysm in a patient with mitral regurgitation: a case report].

A 66-year-old man admitted to our hospital complaining of severe dyspnea. Echocardiography demonstrated severe mitral regurgitation and an abnormal echo at the anterior leaflet of the mitral valve. It was a persistent bulge that protruded toward the left atrium throughout systole and diastole.
