The purpose of this research was to clarify factors that make early hospital discharge difficult. We found that this hospital was different from other general hospitals. We repeatedly revised early discharge guidelines and were able to find factors reliable about 24% higher.
  Our findings would contribute to the shortening of hospital stay, the promotion of the efficiency of our work, the strengthening of regional alliances. What we should consider most important is the realization of the discharge that is not forced.

A 38-year-old woman was referred to our hospital for treatment of infective endocarditis associated with abscesses in the brain and the left lower limb. A causative organism had not been detected by serial blood cultures. Preoperative brain CT revealed mycotic aneurysms and echocardiography showed a mobile vegetation (8mm in size) on the anterior leaflet of the mitral valve. We performed resection of the vegetation together with a small triangle of the anterior leaflet, after which the margins of the defect were approximated. Then bilateral Kay procedures and reinforcement with autologous pericardium were done to obtain proper coaptation. The patient's fever, left lower limb pain, and intracerebral mycotic aneurysms resolved after surgery. The brain abscess also became smaller. Mitral valve plasty should sometimes be considered in the active phase of endocarditis, even in patients with cerebral complications and without congestive heart failure.

A study was conducted to evaluate the clinical and hemodynamic performance of the 19-mm Medtronic Mosaic Valve (MMV) in the aortic position, which is a third-generation stented porcine bioprosthesis. Between 2003 and 2006, 9 patients underwent AVR using the 19-mm MMV. None of the patients were suitable for a 19-mm Perimount bioprosthetic valve due to having a small annulus and sinotubular junction. The patients included 3 men and 6 women with a mean age of 73.2±4.97 years and mean body surface area of 1.35±0.11m². Preoperatively, 8 patients were in New York Heart Association class II and 1 was in class III. The reason for surgery was aortic stenosis in 8 patients and aortic regurgitation due to infective endocarditis in 1 patient. Four patients had chronic renal failure and were on hemodialysis, while 1 patient had Crohn's disease. Concomitant coronary artery bypass grafting was performed in 3 patients, and tricuspid valve annuloplasty was done in 1 patient. The follow-up period was 12.0±7.71 months. No deaths occurred, but there was 1 cerebral infarction. Postoperatively, the peak pressure gradient decreased from 81.3±32.7 to 40.3±16.3mmHg (p<0.01). The mean pressure gradient also decreased significantly from 48.8±11.6mmHg to 23.9±9.32mmHg (p<0.01). Left ventricular end-diastolic diameter was 47.9±3.82mm preoperatively and 45.1±7.53mm postoperatively, showing no significant change. The left ventricular mass index also improved from 217.3±46.9 to 160±54.9g/m² (p<0.05). The ejection fraction was 72.0±8.93% preoperatively and 67.6±6.37% postoperatively, showing no difference. Although the postoperative indexed effective orifice area (EOAI) was 0.90±0.11cm²/m², mild patient-prosthesis mismatch (EOAI 0.77cm²/m²) was noted in 1 patient. In conclusion, the early clinical and hemodynamic performance of the 19-mm MMV in small elderly patients was acceptable.

Perivalvular leakage (PVL) is one of the serious complications of mitral valve replacement. Between 1991 and 2006, 9 patients with mitral PVL underwent reoperation. All of them had severe hemolytic anemia before surgery. The serum lactate dehydrogenase (LDH) level decreased from 2,366±780 IU/l to 599±426 IU/l after surgery. The site of PVL was accurately defined in 7 patients by echocardiography. PVL occurred around the posterior annulus in 3 patients, anterior annulus in 2, anterolateral commissure in 1, and posteromedial commissure in 1. The most frequent cause of PVL was annular calcification in 5 patients. Infection was only noted in 1 patient. In 4 patients, the prosthesis was replaced, while the leak was repaired in 5 patients. There was one operative death, due to multiple organ failure, and 4 late deaths. The cause of late death was cerebral infarction in 1 patient, subarachnoid hemorrhage in 1, sudden death in 1, and congestive heart failure (due to persistent PVL) in 1. Reoperation for PVL due to extensive annular calcification is associated with a high mortality rate and high recurrence rate, making this procedure both challenging and frustrating for surgeons.

Objective: Collection of the latest information for appropriate and safe drug use is clinically essential, and the “Japan Pharmaceutical Association Drug Information” (JPADI) is a useful source.  We prepared a text on the basis of JPADI for undergraduates to learn adverse drug events (ADEs).  The objective of this study was to report the outcomes of our educational plan and student perspectives regarding the management of ADEs.
Methods: We provided 20 students with a self-study text for ADEs, including ADE reports, relief services by the Pharmaceuticals and Medical Devices Agency, and pharmacist medication errors.  Case reports were categorized by disease discipline. Students were administered a questionnaire regarding their evaluation and interest regions of our text, the significance of relief services, and roles of drug information specialist.
Results: Fifteen students (75%) completed the questionnaire.  Interest regions were pharmacist medication errors (n=9), systemic and multi-organ disorders (n=9), and cardiovascular disorders (n=5).  We received comments such as “these errors are experiences creating cascades for the prevention of recurrence” (n=2).  In terms of relief services, “expenses relief ” (n=4) as a merit and “vagueness of relief standards” (n=4) as a demerit were provided.  Roles of drug information specialist included “provide easy-to-understand drug information to patients” (n=4) and “share with other medical staff ” (n=2).  No specific improvements for the text were suggested.
Conclusion: Our educational plan using a self-study text based on drug information is useful for developing student responsibility and expertise for becoming pharmacist.

To assess the changes in attitudes toward smoking after the smoking-prevention classes presented by Kumamoto Tobacco-Free Forum, this study administered a questionnaire survey to first-year junior high school students before and after a smoking-prevention class at a junior high school. The questionnaire that was used to pre and post comparison comprised thirteen items, ten from the Kano Test for Social Nicotine Dependence (KTSND-Youth) and three as follows: “I think I will be a smoker in the future,” “I think I will smoke about once,” and “What do you think of people around you who smoke tobacco?” The results of this pre- and post-class questionnaire indicate that attitudes toward seven items improved in a statistically significant way. These included four from KTSND-Youth: “Smokers cannot stop even if they want to,” “Smoking is adult-like and cool,” “Smoking is enjoys taste and a fragrance,” and “If it’s a place with an ashtray, it’s okay to smoke.” The smoking-prevention classes significantly decreased total KTSND-Youth scores. Furthermore, the analysis has clarified that the KTSND-Youth items: “Smoking is adult-like and cool” and “Doctor and school teachers say, ‘Tobacco is no good too much”, as well as the item “What do you think of people around you who smoke tobacco?” are significantly influencing factors for the item “I will be a smoker in the future.” These results indicate that the smoking-prevention classes presented by Kumamoto Tobacco-Free Forum were effective for decline in social nicotine dependence of the first-year students in junior high school.

Isolated unilateral absence of the right pulmonary artery without any intracardiac anomaly is a rare congenital cardiovascular disorder. We performed a successful surgical reconstruction with autologous tissue of this anomaly. The patient was a 1-month-old boy who had been transferred to our center at 3 days of age because of tachypnea and heart murmur. Multi-detector CT and radial angiography imaging revealed isolated unilateral absence of the right pulmonary artery and left patent ductus arteriosus. Conservative treatment did not help his progressive heart failure and pulmonary hypertension due to an acute increase of pulmonary blood flow. Therefore surgical correction was determined to avoid the worsening of those symptoms. Under cardiopulmonary bypass, the right pulmonary artery branching off from the brachiocephalic artery was removed and anastomosed to the main pulmonary artery with an autologous pericardium roll. Symptoms improved postoperatively and he was discharged in good condition on the 21st of postoperative day. Cardiac catheterization, 3 months later, showed excellent results.

A 66-year-old woman who had percutaneous mitral valve commissurotomy 12 years before was admitted complaining of dyspnea on effort. Echocardiography showed severe mitral stenosis and regurgitation, and moderate tricuspid regurgitation associated with atrial fibrillation. Based on her past history we suspected allergy to metal, and skin patch tests showed a positive reaction to zinc, manganese, nickel, cobalt, dichromate, stainless steel, titanium alloys, and nickel-chromium-cobalt alloys. We selected an artificial organ which would not cause an allergic reaction. The St. Jude Medical standard cuff mechanical valve was the only compatible prosthetic valve. Anterolateral right thoracotomy, instead of median sternotomy, was selected. Mitral valve replacement with a 27-mm St. Jude Medical standard cuff mechanical valve and tricuspid valve annuloplasty with a 27-mm Duran flexible band were performed. Her postoperative course was uneventful. She is doing well without any allergic symptom 18 months after the surgery.

Periannular abscess and mycotic aneurysm due to infective endocarditis are very difficult conditions to treat surgically. Beginning in 1983, we introduced a translocation technique on 9 such cases. In particular, 7 patients who underwent a new sutureless translocation technique all showed an uneventful course and were discharged. There was no hospital death, but four patients died in the late period (2 heart failure, 1 ventricular tachycardia and 1 thrombotic valve). The sutureless translocation method consists of insertion of a composite valve into the ascending aorta (a ring was detached from an intraluminal ringed graft and a prosthetic valve was sutured to it at that point) and coronary artery bypass grafting to the right and left coronary arteries. Our new technique was simple, required only a short aortic clamping time (mean 173.9min) and there was no significant bleeding. This new translocation technique provides a solution for the treatment of periannular abscess and mycotic aneurysm due to infective endocarditis.
