A 58 year-old man was referred to our hospital with a fever after dental treatment. He had undergone an operation for aortic root replacement 9 months earlier. Streptococcus species were cultured with venous blood culture. An echocardiogram revealed vegetation attached to the prosthetic valve. The prosthetic valve function was good and he did not suffer from heart failure, therefore he was treated with antibiotics. Five days after starting antibiotics, we observed embolization of the brain and the kidney as well as an elevation of his inflammatory reaction. Accordingly, we performed emergency surgery. There was no paravalvular abscess or valve dysfunction, so we simply resected the vegetation and debrided the surrounding tissue. Post-surgical antibiotic therapy was continued for 5 weeks and then he was switched to oral medication. Three years after surgery, he is free from any PVE recurrence.

Japan introduced a mandatory residency program in 2004. Teaching hospitals are now responsible for improving patient safety and the overall teaching environment. Questionnaires were sent to teaching hospitals in Kyushu to evaluate residents' work environments and to ask them about improving patient safety. Questionnaires asked about the work environment, experience with medical errors and adverse events, self-reported work conditions, personal anxiety levels about medical errors, and personal suggestions for decreasing medical errors. One hundred eight questionnaires were mailed, and 76 (70.3%) were returned complete and were analyzed. Most residents in Japan work long hours, feel extremely busy, and are anxious about medical errors; many of them reported personal involvement in medical errors or adverse events. Their suggestions to improve patient safety included improvement of the work environment, establishment of a resident support system, and better organization of medical charts and equipment. Considering residents' viewpoints for patient safety is important to help reduce errors in teaching hospitals.

We report a rare case of severe aortic regurgitation after mitral valve replacement (MVR) and tricuspid annuloplasty (TAP). An 83-year-old woman underwent MVR and TAP for mitral regurgitation and secondary tricuspid regurgitation. The early postoperative course was not eventful until 6 days after surgery. However, 7 days after surgery, she suffered from acute heart failure and transthoracic echocardiography showed severe aortic regurgitation. We performed a second operation 13 days after the first surgery. Intraoperatively, we found the annulus suture of the TAP just under the NCC-RCC commissure of the aortic valve. We speculated that the suture pulled the aortic valve annulus, resulting in severe aortic regurgitation. We removed the suture and replaced the aortic valve with bioprosthetic artificial valve. Postoperative recovery was uneventful, and she was discharged 22 days after the second surgical procedure.

BACKGROUND/AIMS: The aim of this study was to examine the convenience of the quality of life and utility evaluation survey technology (QUEST) questionnaire and the frequency scale for the symptoms of gastroesophageal reflux disease (FSSG) questionnaire as self-assessment diagnostic instrument. METHODS: This was a two-way crossover study conducted over 6 weeks from September 2010 to November 2010. The subjects were 60 consecutive patients admitted to the Hiratsuka city hospital with a gastrointestinal condition, regardless of the coexistence of heartburn. They were assigned to fill in both the QUEST and FSSG questionnaires in random order. We analyzed the time taken to complete the questionnaires, whether subjects asked any questions as they filled in the questionnaire, and the questionnaire scores. RESULTS: Comparison of the QUEST and the FSSG revealed significant differences in the completion time (196.5 vs. 97.5 seconds, respectively; P < 0.0001) and in whether subjects asked any questions (37 vs. 15 subjects, respectively; P < 0.0001). Completion time in QUEST scores of > or = 4 was lower than < 4 (170.5 vs. 214.0 seconds, respectively; P = 0.022), and the QUEST score was significantly higher without questions than with question (3 vs. 1 points, respectively; P = 0.025). CONCLUSIONS: This study revealed that the FSSG questionnaire may be easier for Japanese subjects to complete than the QUEST questionnaire.

BACKGROUND/AIMS: The effects of Histamine-2 receptor antagonists and proton pump inhibitors on the gastrointestinal motility have not yet been sufficiently investigated. The aim of this study was to determine the effects of intravenous bolus administration of famotidine and omeprazole on the rate of gastric emptying using the continuous 13C breath test (BreathID system, Exalenz Bioscience Ltd, Israel). METHODS: Twelve healthy male volunteers participated in this randomized, 3-way crossover study. After fasting overnight, the subjects were randomly assigned to receive 20 mg of famotidine, 20 mg of omeprazole or 20 mL of saline alone by intravenous bolus injection before a test meal (200 kcal per 200 mL, containing 100 mg of 13C-acetate). Gastric emptying was monitored for 4 hours after the ingestion of test meal by the 13C-acetic acid breath test performed using the BreathID system. RESULTS: No significant differences in the calculated parameters, namely, the T1/2, Tlag, GEC, beta and kappa, were observed among the 3 test conditions. CONCLUSIONS: The study revealed that intravenous administration of gastric acid suppressant drugs had no significant influence on the rate of gastric emptying in comparison with that of saline alone as a placebo. Our results indicating the absence of any effect of either famotidine or omeprazole on accelerating the rate of gastric emptying suggest that both medications can be administered safely to patients suffering from hemorrhagic peptic ulcers who need to be kept nil by mouth from the viewpoint of possible acceleration of gastrointestinal motility in the clinical setting.

Infective endocarditis of the aortic valve tends to cause structural damage such as aortic root abscess, and aortic valve replacement is the standard treatment. However, there have been several reports on aortic valve repair for the treatment of infective endocarditis, and it has subsequently emerged as a feasible alternative to aortic valve replacement in selected patients. We report a case of aortic valve repair for infective endocarditis of the aortic valve caused by α-hemolytic Streptococcus. A 50-year-old man was admitted to our hospital with a two-month history of fever of unidentified origin. Transthoracic echocardiography revealed infective endocarditis of the aortic valve. Transesophageal echocardiography confirmed vegetation in the right coronary and non-coronary cusps, and mild aortic regurgitation. Although infection was controlled by approximately one month of antibiotic treatment, there was markedly more severe aortic regurgitation compared to the previous examination. These findings were confirmed on transesophageal echocardiography, and residual vegetation on the right coronary cusp as well as a perforation in the non-coronary cusp were confirmed. Intraoperative findings revealed a perforation in the non-coronary cusp and dehiscence, with vegetation on the right coronary cusp. The vegetation was carefully removed, the non-coronary cusp perforation was repaired with a pericardium patch, and the defect on the right coronary cusp was directly sutured with 6-0 polypropylene. Intraoperative transesophageal echocardiography revealed trivial aortic regurgitation. The postoperative course was uneventful and the patient was discharged 7 days after surgery without any complications. Antibiotics were prescribed for 3 months, and transthoracic echocardiography was performed 5 days, 1 month, and 3 months after surgery. No evidence of recurrence of aortic regurgitation or infection of the aortic valve was observed.

Reoperative valve surgery is known to be more complex and associated with increased morbidity and mortality, especially for patients with patent coronary artery bypass grafts. A 69-year old man with a history of coronary artery bypass grafting was referred to our hospital with breathing difficulties and a heart murmur. Bypass grafts were all patent, but due to severe ischemic mitral valve regurgitation, we performed beating heart mitral valve replacement via right thoracotomy. The procedure was performed with video assistance, and both the anterior and the posterior chordae tendineae were preserved. The postoperative course was uneventful. He was discharged 7 days after surgery without any complications. This technique is a safe and feasible option for a mitral valve reoperation that avoids graft injuries, minimizes the risks of bleeding, and shortens the operative time.
