Clinical Study of Mamushi Viper Bites in 35 Cases / 日本農村医学会雑誌

Mamushi is a species of pit viper distributed throughout Japan excluling the Ryukyu Islands and sighted from spring to autumn. It is estimated that about ten people dies in a year. It is important in the rural medicine because a lot of people are bitten in mountains and fields. A total of 35 cases of mamushi viper bite were treated from 1999 to 2006 in our hospital. The patients were 17 men and 18 women ranging in age from 7 to 80 years old (average: 60). Local swelling and pain were manifest in all the cases. Sixteen patients had systemic symptoms, and toxic effects commonly appeared in the eyes. The blood tests revealed elevated CPK levels in 24 patients (69%). The elevation correlated to the seriousness of the clinical symptoms. In accordance with our manual for mamushi viper bites, all patients were hospitalized after incision for exclusion of the toxin. The median length of time before the worst symptoms began to subside was 3 days. The median length of hospitalization stays was 7 days. It took long before the patients fully recovered. The severity of envenomation was different from patient to patient and one case needed intensive care. The median of treatment period was 31 days. The quick and appropriate primary care for the mamushi viper bits is important to prevent serious complications.

Perioperative Management to Prevent Postoperative Pulmonary Embolism in General Surgical Patients / 日本農村医学会雑誌

Recently, the incidence of pulmonary embolism (PE) after surgery began to increase in Japan and to prevent PE has become essentially important. During the period between July 2003 and August 2004, we placed 203 general surgical patients under our perioperative management using intermittent pneumatic compression (IPC) and compression stockings (CS). We evaluated the effect of our management on the prevention of postoperative PE in those patients. The incidence of PE, prognosis, complications, patient's complaints, cost-benefit were examined. No fatal PE occurred. One patient with low SpO2 had a chest pain and dyspnea but pulmonary scintigrams revealed no PE. Two other patients had contact dermatitis by CS and another patient using an epidural catheter suffered temporary paraplegia after heparin injection. The government has approved a fee for PE prophylaxis since April 2004. Our management using IPC and CS for PE prophylaxis after surgery proved to be an effective in reducing the risk of PE. However, we must take the atmost care in injecting heparin into patients with epidural catheters.

Evaluation of Quality of Life in Patients with Breast Cancer Treated with Chemotherapy / 日本農村医学会雑誌

Recently the evaluation of health-related quality of life (QOL) in cancer patients has become important in carrying out a treatment strategy. During a period between June and August 2004, we studied the QOL in 16 breast cancer patients with or without chemotherapy. The regimens of chemotherapy were EC (n=6), AT (n=1) and CMF (n=1). We made the Functional Assessment of Cancer Therapy Scale-General (FACT-G) in all patients. The patients treated without chemotherapy were superior to those with chemotherapy with respect to physical and emotional well-being (p<0.05). There were no differences in social well-being and relationship to families between the two groups. The patients treated without chemotherapy made significantly higher scores in the basic activities of daily living than those with chemotherapy (p<0.05). Compared with patients receiving chemotherapy, patients treated without chemotherapy had better quality of life (p<0.05). We concluded that it was important for us to assist in decision making about treatment and supportive care needs.

Surgical Treatment of Multiple Aneurysms / 日本心臓血管外科学会雑誌

Morphology, location, timing of operation, and complications of multiple aortic aneurysms were investigated in 14 patients (10 men and 4 women with a mean age of 66 years). The locations of the aneurysms were as follows: aortic arch and thoracoabdominal aorta in 1, aortic arch and infrarenal abdominal aorta in 6, descending thoracic aorta and suprarenal abdominal aorta in 1, descending thoracic aorta and infrarenal abdominal aorta in 5, and thoracoabdominal aorta and infrarenal abdominal aorta in 1. Thoracic aortic aneurysms had a mean diameter of 63±13mm. The mean diameter of the abdominal aortic aneurysms was 54±13mm. In 1 patient, thoracoabdominal and infrarenal abdominal aortic aneurysms were operated on simultaneously. Eight patients, 5 with aneurysms of the aortic arch and infrarenal abdominal aorta, 2 with aneurysms of the descending aorta and infrarenal abdominal aorta, and 1 with aneurysms of the aortic arch and thoracoabdominal aorta, underwent two-staged operation. Aortic arch aneurysm was operated first in 3 patients, and abdominal aortic aneurysm in 5. Postoperative complications included spinal cord injury in 1 patient, bowel necrosis in 1, renal impairment in 2, respiratory impairment in 2, and hepatic impairment in 1. There was no perioperative death. Three late deaths occurred. Two staged operation is better for multiple aortic aneurysms. The first operation should be performed for the larger aneurysm.
