A 65-year-old woman was admitted with a diagnosis of unstable angina after PTCA. She was diagnosed with acromegaly 8 years ago. She underwent an emergency coronary artery bypass grafting (LITA-LAD, SVG-HL-Cx). Serum growth hormone (GH) levels were 65.5ng/ml (normal limit<5ng/ml) before the operation. During a cardiopulmonary bypass GH levels elevated to 92.7ng/ml, but decreased to 15.9ng/ml after the operation. After 3 postoperative days GH levels increased gradually again and blood sugar levels became unstable. Finally it was necessary to increase the dose of bromocriptine. To our knowledge, there are only a few patients who have undergone coronary artery bypass grafting associated with acromegaly. This case suggests it is important to control GH levels at the operation and during the postoperative period.

We administered Bofutsushosan (Bo) to 127 obese patients who consulted our clinic, and investigated the effect of this herbal formula on reducing body weight in 33 obese patients who received continuous adminis tration for more than six months. The abdominal muscle tension of these 33 patients was assessed mainly as “strong” (four) under the five-grade scale of Kampo diagnostics, which was higher than that of 9 other patients with side effects (including diarrhea and abdominal pain) assessed mainly as “middle” (three). Sixteen patients reported a decrease in appetite following administration of Bo. Weight before medication in the patients with decreased appetite was 67.1±2.5kg, and that in 17 patients with unchanged appetite was 75.9±2.4kg. There was a significant difference between the two. Weight change in the patients with decreased appetite was -4.8±1.0kg and was significantly lower than -1.4±0.7kg in the patients with unchanged appetite. Their blood triglycerides levels decreased significantly following administration of Bo. This decrease in appetite was considered to be due not only to activation of the adrenaline β₃ receptor, through the administration of Ephedrae Herba, Schizonepetae Spica, Rhei Rhizoma, Forsythiae Fructus and Glycyrrhizae Radix but also to the psychotropic actions of Ephedra Herba, Rhei Rhizoma and Gardeniae Fructus. Recently severe side effects of Bo have been reported. This study suggested that patients showing a grade of strong (four) or more in abdominal muscle tension, were indicated for this treatment and that the long-term administration of this herbal formula should be continued in patients whose appetite was identified as being suppressed.

Objective: Finger-tip unit (FTU) has been used in Western countries to apply a specific amount of steroid ointment available in tube form.  Although prescription ointments for treating skin disorders are available in Japan, there are no indications for patients regarding the amount to be used.  Therefore, we investigated the factual assessment of patient compliance instructions on using the ointments given by pharmacists and conducted a comparative test on the amount of ointment in 1 FTU using commercially available ointment tube products.
Methods: We conducted a questionnaire survey for 21 hospital pharmacists on patient compliance instructions for ointments.  Using six types of ointments, we measured the aperture area of ointment tube, weight of 1 FTU and squeezing number of tube.
Results: Fewer than 50% of pharmacists explained the application methods and amounts for one-time use when they provided patient compliance instructions.  There were many patients who used an ointment inadequately.  The most were problems about the quantity of application.  Wide variations were found among the amount of ointment in 1 FTU weight and number of available uses.
Conclusion: The survey results demonstrated that the methods used to apply the ointments are items that must also be emphasized by pharmacists when providing patients compliance instructions.  Furthermore, the patient compliance instructions should include the amount of ointment in 1 FTU and number of available uses within pharmaceutical products.

　　With a view to preventing surgical site infection (SSI), administration of antimicrobial agents during surgery should be performed every 3-4 hours after the first administration before surgery begins. In our hospital, the infection control team (ICT) tried to intervene with surgeons and all operating room staff to improve compliance with the administration of antimicrobial agents. The purpose of this study was to evaluate the impact of this intervention by the ICT on correct administration of antimicrobial agents during surgery. In total, 435 surgeries which included ≥ 210 min under anesthesia or 180 min of the operation were analyzed. All antimicrobial agents were first administered within 60 min before the start of surgery. At some point, the ICT intervened, recommending that antimicrobials be administered every 3 h during surgery. The compliance rate (CR) of surgeries for the correct administration of antimicrobial agents was investigated. Differences in CR were evaluated (1) among departments (gastroenterology and general medicine [GM], orthopedic surgery [OR], otorhinolaryngology [OL], gynecology [GY], and urology [UR]), (2) whether intervention of ICT was carried out or not, and (3) in terms of specific procedures (endoscopy and laparoscopy). Total CR was 51.0% (GM: 67.0%, OR: 27.1%, OL: 40.5%, GY: 45.5%, and UR: 37.5%). CR was significantly higher in GM than in any other departments. CR with and without intervention was 69.9% and 42.7%, respectively, and this was statistically significant. CR in endoscopy was 25.8%, which was significantly lower than that in other surgeries (55.2%). CR in laparoscopy was 63.1%, which was significantly higher than that in other surgeries (47.3%). Intervention by the ICT resulted in significant improvement of CR for correct administration of antimicrobial agents. However, CR was low in some situations. This could be improved by more careful dialogue with surgeons and operating room staff.

The patient is a 47-year-old male who presented with abnormal shadows in his chest X-ray. On the third intercostal space, diastolic regurgitant murmur and systolic ejection murmur were heard. X-ray of the chest showed a projection of the right second costal arch in addition to the right atrium shadow. Cardiac catheterization showed no abnormalities except for a rise in the left ventricular end diastolic pressure which was 18mmHg. The patient was found to have Grade II aortic regurgitation. All there findings diagnosis of the case as extra-cardiac right Valsalva sinus aneurysm with aortic regurgitation. Incision of the aneurysm, showed a Valsalva sinus aneurysm having an opening of approximately 3cm just above the right aortic valve ring with the orifice of the right coronary artery occluded. Complete patch closure was performed with elevation of the aortic valve ring. No reconstruction for the right coronary artery was made.

We evaluated 13 patients (4 men & 9 women, mean age: 61 years-old) who required steroid treatment for more than 1 month before open heart surgery. The subjects included 3 patients with collagen diseases, 3 with dermatopathy, 2 with bronchial asthma, one each with Takayasu's disease, autoimmune hemolytic anemia, paroxysmal nocturnal hemoglobinuria, brain tumor and post-renal transplantation. Surgical procedures were performed with an AC bypass in 9 cases, one each with AVR, MVR, reMVR and ASD patch closure. The steroid treatment before open heart surgery had been continued for a mean of 4 years and 11 months at a mean dose of 9.4mg/day equivalent of prednisolone. We evaluated the adrenocortical function on the rapid ACTH test and found hypoadrenalism in 5 of 8 cases (63%). In these cases we gave either 100mg of hydrocortisone or 1, 000mg of methylprednisolone before open heart surgery. The total perioperative dosage of steroid was a mean of 2, 488mg equivalent of prednisolone, including 4mg/kg of betamethasone during the extra corporeal circulation. Postoperatively we lost one case due to ventricular rupture after MVR. Other major complications were seen in one case each, cardiac tamponade, temporary clamp, wound infection and lumbar vertebral fracture. For steroid treated patients, it is important to select the patient who really need steroid by the rapid ACTH test, and to use the minimum dosage of steroids in open heart surgery.

A 72-year-old woman underwent simultaneous combined surgical treatment for descending aortic aneurysm, coronary artery disease and left common iliac artery stenoses. The operation was performed through the left posterolateral thoracotomy via the 6th intercostal space and a left retroperitoneal approach. At first, 10mm woven Dacron graft was anastomosed to the abdominal aorta as an inlet of the cardiopulmonary bypass and the left femoral vein was used for venous drainage. A saphenous vein graft was anastomosed to the left anterior descending artery during partial cardiopulmonary bypass with the heart beating. Secondly, the aneurysm was replaced with 24mm woven Dacron graft. Thirdly, the proximal end of the vein graft was anastomosed to the Dacron graft of the descending aorta. Finally after cardiopulmonary bypass was terminated, the distal end of the woven Dacron graft for arterial perfusion was anastomosed to the left external iliac artery in end-to-side fashion. The postoperative course was uneventful. We conclude that simultaneous operation for descending aortic aneurysm and coronary artery bypass grafting through left thoracotomy with the heart beating is useful in these combined diseases.

The Ministry of Health and Welfare of Japan is planning a pooling system for multiple-choice questions (MCQs) for the national examination for medical practitioners. To clarify possible problems of such a system, a field study was performed by 10 medical schools in Japan using 90 MCQs from previous examinations. Nine hundred twenty-four 6th-year students participated in the field test. For each MCQ, the correct-response rates at the originating school and those obtained in the field test were significantly correlated. Thus, the correct-response rates to questions on the field test could be predicted from the rates at the originating schools. However, for each question the correct-response rate was significantly higher for students of the originating school than for students of other schools. In the national examination, care should be taken to prevent differences in scores on the basis of question sources.

This study was designed to evaluate the late changes of coronary bypass grafts in 60 patients who had undergone coronary bypass surgery and postoperative angiography in the period from 1994 to 1999. Angiography was performed at mean intervals of 84 months and a total of 134 grafts and 162 anastomoses were visualized. The Left internal thoracic artery and saphenous vein had a patency of 85% and 82%, there was not statistically significant. In this series, late graft function did not relate to the site of implantation, that was mainly due to excellent results of saphenous vein grafts. With increasing proximal stenosis severity (under 75% versus over 90%), there was an increase in patency rates and this relationship was statistically significant (p=0.0005). That was why about 20% of the grafts to moderately stenotic target vessels had occluded within 1 month after surgery. Ten patients among these 60 had cardiac symptoms, 6 were due to graft failure and the other 4 were due to new lesions in the right coronary artery. In the other 12 patients new coronary artery lesions without cardiac symptoms had been detected. Periodic coronary examinations should be recommended for the patients after surgery, regardless of the absence of symptoms.

A 71-year-old woman underwent mitral valve replacement with Carpentier-Edwards Pericardial Xenograft for mitral regurgitation on January 8, 1987. She had nocturnal hematuria and paroxysmal nocturnal hemoglobinuria was diagnosed in November, 1992. She had congestive heart failure in February, 1993. Cineradiographical analysis revealed a fracture of the wireform in three locations of the Xenograft and the stent was distorted inward. A second mitral valve replacement was successfully performed on March 16, 1993. She was discharged 45 days after operation after an uneventful course.
