Introduction: CPT-11 induced diarrhea reduces patient compliance, lowers quality of life, and can be potentially life threatening. Loperamide is effective in the majority of cases of CPT-11-induced diarrhea. However, the case of advanced gastrointestinal cancer where oral administration is difficult. We adapted octreotide for use in a case of CPT-11-induced diarrhea where oral administration was difficult due to digestive tract stenosis. Case Report: A 61-year old man was diagnosed with advanced gastric cancer. He was treated with CPT-11 100mg/m² weekly for three weeks followed by a 1-week rest. CPT-11-induced diarrhea developed after 10 days of treatment. At the same time, his digestive tract stenosis worsened, making Loperamide unusable. We administered octreotide 200μg continuous intravenous drip infusion. One day after octreotide administration, the number of diarrhea has decreased from 20 times to four times. Conclusions: Octreotide is one of the effective treatments for CPT-11-induced diarrhea. Palliat Care Res 2010; 5(2): 338-341

The aim of this study was to investigate the relationship between heart rate variability (HRV) during exercise and ventilatory threshold (VT), using the MemCalc system which is superior in spectral analysis. Nine healthy male subjects with no cardiopulmonary disease performed an exercise test to exhaustion to determine VT on a bicycle ergometer. Low frequency (LF : 0.04-0.15 Hz), high frequency (HF : 0.15-0.40Hz) and LF/HF ratio power spectra were calculated by maximum entropy method (MEM) spectral analysis, using the MemCalc system. In each case, when the subject started exercise, the HF component declined rapidly during the first 30 seconds ; and compared to the resting value, it declined to approximately 5 % at VT. The possibility of using this phenomenon as a criterion for setting intensity of exercise is tinder consideration. The LF/HF ratio showed different patterns of variation among the subjects. A significant linear relationship was seen between the declining rate of the HF component and VT (r=0.93, p<0.001), suggesting a corres pondence between the heart's capability of adjusting to maintained exercise and high endurance capacity.

The magnitude of mechanical stress at the shoulder and elbow appears to be directly correlated with the degree of maximum shoulder external rotation (MER) during throwing. Therefore, it is very important to prevent excessive MER to minimize the risk of throwing injuries. The purpose of this study was to investigate the relationships between MER during throwing and the kinematic parameters of throwing mechanics, shoulder muscle strength, and shoulder range of motion in high school baseball players. The subjects were 40 male high school baseball players with no elbow or shoulder joint problems. Three-dimensional analysis was performed to calculate the MER angle. Then, the shoulder and elbow angles at initial foot contact (IFC) were computed. ROM and muscle strength of shoulder joint were also measured in each subject. Multiple linear regression analysis was used to relate the MER angle to these factors. Significant correlations were observed between the MER angle and the external rotation (ER) angle (r=−0.51, p<0.001) at IFC, and the ER range of motion (r=0.84, p<0.01). The MER angle significantly correlated with shoulder internal rotation (IR) at IFC. This finding suggests that stress on the shoulder and elbow could be increased by the degree of shoulder IR angle at the moment of IFC. Further, excessive ER range of motion may also be a risk factor.

We studied the incidence of associated ischemic heart disease (IHD) among 143 consecutive patients (male 118, female 25, mean age 68.5±6.9 years) operated upon for abdominal aortic aneurysm (AAA), excluding ruptured aneurysms. The screening of IHD was routinely performed by using dipyridamole thallium scintigraphy, and when it was positive, the lesion was further confirmed by selective coronary angiography. More than 50% luminal stenosis of the major coronary arteries was judged positive for IHD. Sixty-two patients (43%) with AAA were simultaneously afflicated with IHD. We also compared the 62 AAA patients with IHD with the remaining 81 AAA patients in this series. The patients with IHD had higher incidences of risk factors such as diabetes mellitus (p=0.0031) and hyperlipidemia (p=0.0029) than those without IHD. Five patients were operated on for AAA after coronary artery bypass grafting (CABG), 11 were operated on for AAA and IHD (CABG) simultaneously, 10 were operated on after PTCA, thirty-two patients underwent elective surgery for AAA and four had emergency procedures due to impending rupture of AAA with continuous infusion of nitroglycerin with or without diltiazem. There was no significant difference in surgical mortality between AAA patients with IHD and those without IHD (3%vs2%), and no cardiac death in this series. When both AAA and IHD are severe enough to warrant surgical treatments at the earliest opportunity, we recommend concomitant operations for AAA and IHD (CABG) since these have been performed quite successfully in our series.

A 48-year-old man complained of hemoptysis. Chest CT scan showed a large cardiac tumor invading the atrial septum and both atria, as well as multiple small nodules in bilateral lung fields. They were diagnosed as a malignant cardiac tumor and its lung metastases. As the tumor in the left atrium was extremely massive, operation was performed to prevent sudden death due to occlusion and to make a pathological diagnosis. The cardiac tumor invaded the atrial septum from the right atrium and occupied the left atrium. After the cardiac tumor was completely removed, the bilateral atria, the atrial septum, SVC, IVC and the right lower pulmonary vein were reconstructed with prosthetic pericardial patches. The tumor was angiosarcoma. During the postoperative period, Interleukin-2 was used as the treatment for angiosarcoma. Unfortunately the patient died of lung failure on the 107th postoperative day. Though IL-2 could not stop the development of lung metastasis in this case, the effectiveness of radiotherapy or IL-2 for angiosarcoma has recently been reported. In such cases where complete resection of the primary cardiac lesion is possible, postoperative radiotherapy or IL-2 administration seems to be effective for cardiac sarcoma.

The working group to improve foreign language education in medical schools established in 1994 and chaired by K. Uemura, M.D. sent questionaire about their present curricula and future plans for teaching English to the deans of all 49 public and 31 private medical schools from January 9 to March 9, 1995, and collected the responses from 30 (61.2%) public, 24 (77.4%) private, in total 54 (67.5%) medical schools. The teaching of useful English includes English conversation in 37 (68.5%), medical English in 34 (63.0%), and structures of medical papers in 9 (16.7%) schools. Medical English is also taught as extracurricular and other activities in 40 (74.1%) schools. These figures have increased as compared with the ques-tionaire conducted two years previously. English conversation can be taught to junior (1st & 2nd yrs) students, for whom medical English can only be taught on general medical topics such as the medical care delivery system, bioethics, roles of physicians, and primay care. Therefore medical English is more and more taught to middle-class (3rd & 4th yrs) and senior (5th & 6th yrs) students. It seems necessary to annually conduct a workshop for medical English teachers to improve their strategies of teaching.

The working group to improve foreign language education in medical schools established in 1994 and chaired by K. Uemura, M.D. here proposes a model curriculum for teaching useful English in medical schools at three levels. The major objectives are listening, speaking, rapid reading, and sentence structuring including paragraphing for junior (1st & 2nd yrs) students, reading medical papers and charts in English, structures of medical scientific papers, and listening to medical English for middleclass (3rd & 4th yrs) students, and writing and orally presenting papers in English on given medical subjects are for senior (5th & 6th yrs) students.

The Working Group for the Improvement of Foreign Language Education in Medical Schools in Japan, organized in 1994 and chaired by Prof. K. Uemura, M.D. lists here English teaching materials for medical purposes. More than half of the materials listed are those that one of the group members, T. Ohki, has used or wants to use in his classes. The list has been enlarged due to the responses to the questionnare sent to those who participated in the first workshop held in 1995. The list is divided into 12 categories: listening & reading, writing, medical terminology, pronunciation, textbooks for training the four skills, essays on medicine, fictional stories about medicine & medical doctors, medical ethics and terminal care, handbooks for medical students and doctors, writing medical charts, self-teaching materials. and video materials.
It is hoped that the materials listed here will supplement a model curriculum for teaching ‘useful’ English in medical schools, as proposed by the working group.

Ruptured type B acute aortic dissection (AAD) is a life-threatening condition, in which surgical treatment most often yields unsatisfactory results. We report a case of a ruptured type B AAD in a 67-year-old man detected on computed tomography that required a partial aortic arch replacement with reconstruction of the left subclavian artery with adjunct deep hypothermic circulatory arrest (DHCA). Although the patient had a postoperative stroke, he recovered markedly with rehabilitation. DHCA and open proximal anastomosis are useful for the surgical treatment of type B AAD, however, an elaborate strategy to prevent an intraoperative cerebral embolism is especially important.
