A 53-year-old woman underwent mitral valve replacement for congestive heart failure due to mitral stenosis and regurgitation. She had been receiving hemodialysis because of diabetic nephropathy since 1993, and had had congestive heart failure since 1999. Echocardiography demonstrated mitral stenosis (MVA; 1.10cm²) and regurgitation with a severely calcified mitral annulus. Annular calcification extended to the posterior wall of the left ventricle and the base of bilateral papillary muscles. After removing all calcium from the mitral annulus to the base of the papillary muscle, the left ventricular posterior wall and mitral annulus were reconstructed by glutaraldehyde-preserved autologous pericardium. Then, a Carbo-Medics mechanical valve was placed at the mitral annulus using everting mattress sutures. Although her hemodynamics were stable, bacteremia and multi-organ failure developed 3 months after surgery and she died. Autopsy showed that the reconstructed left ventricular posterior wall and mitral annulus using glutaraldehyde preserved autologous pericardium were in excellent condition without any thrombus. No dehiscence was found at the suture line of the mechanical valve. Mitral annulus reconstruction with glutaraldehyde preserved autologous pericardium is thought to be effective for patients with calcified mitral annulus who require mitral valve surgery.

Myxoma of the left ventricle is exceedingly rare and to the best of our knowledge not a single case of its recurrence has been reported in Japan. We have recently experienced a case in which a myxomatous tumor of the left ventricle recurred at the same site as the primary lesion 2.5 years after operation and was treated by surgical excision. The patient was a 28-year-old female who, under the diagnosis of myxoma of the left ventricle, underwent surgical removal of the tumor and mitral valve replacement at her age of 25 years. Although her postoperative course was uneventful, she was noticed, at her age of 28 years, of her inaudible prosthetic valve clicks on auscultation at the outpatient service. Echocardiography revealed a tumor mass in the left ventricle, which tended to grow with the elapse of time. Echocardiography on rehospitalization disclosed a mobile cystic tumor on the posterior wall of the left ventricle, while pulmonary arteriography also revealed a movable tumor in the left ventricle. Intraoperatively, there was noted a solid tumor, composed partly of cystic structure, on the posterior wall of the left ventricle and quick pathology led to a suspected diagnosis of myxoma. Since the tumor was found to have involved the ventricular septum and myocardial tissue of the posterior wall of the left ventricle, its complete surgical excision was impossible. The tumor, with its growth pattern and morphology, was diagnosed as a malignant clinical behavior one, although histopathological evidence indicates its benignancy.

To analyze the effect of trabeculotomy on open angle glaucoma in Kansai Medical University, Kouri Hospital, thirty-eight eyes of 26 patients underwent trabeculotomy procedure by one surgeon.The average of intraocular pressure (IOP) after trabeculotomy was 17.7+_ 7.6 mm Hg and their success rate of 5 years was 51.2% by Kaplan-Meier's life analysis method.Trabeculotomy had no serious complications, but 21% showed progression in Goldman perimetry study.Setting the target IOP under 14 mm Hg, such as in progressive glaucomatous eyes, trabeculotomy is second to filtering surgery with MMC.But traceculotomy is basically maintenance-free procedure, so it is useful for actively working patients to reduce some eye drops for glaucoma,

Objective: Several evidence-based practice guidelines have been developed to better treat bipolar disorder. However, the articles cited in these guidelines were based on clinical or basic studies with specific conditional settings and were not sufficiently based on real-world clinical practice. In particular, there was little information on the doses of mood stabilizers. Methods: The MUlticenter treatment SUrvey on BIpolar disorder in Japanese psychiatric clinics (MUSUBI) is a study conducted to accumulate evidence on the real-world practical treatment of bipolar disorder. The questionnaire included patient characteristics such as comorbidities, mental status, treatment period, Global Assessment of Functioning (GAF) score, and details of pharmacological treatment. Results: Most patients received mood stabilizers such as lithium (n = 1,317), valproic acid (n = 808), carbamazepine (n = 136), and lamotrigine (n = 665). The dose of lithium was correlated with age, body weight, number of episodes, depression and GAF. The dose of valproic acid was correlated with body weight, number of episodes, presence of a rapid cycle and GAF. The dose of carbamazepine was correlated with age, mania, and the presence of a rapid cycle. The dose of lamotrigine was correlated with the number of episodes, depression, mania, psychotic features, and the presence of a rapid cycle. Doses of coadministered mood stabilizers were significantly correlated, except for the combination of valproic acid and lamotrigine. Conclusion The dose of mood stabilizers was selectively administered based on several factors, such as age, body composition, current mood status and functioning. Further prospective studies are required to confirm these findings.
