Methods@#Thirty patients with LSS scheduled for spine surgery participated in this study. Lower limb pain was assessed using the Visual Analog Scale (VAS), and the patients were divided into two groups based on the mean scores (patients with scores above and below the mean were classified as the high-VAS and low-VAS groups, respectively). The kinematics of the spine, pelvis, and hip joints during gait were then measured using a 3D motion analysis system. Student paired t -tests were used to compare the angles of the spine, pelvis, and hip during gait between the two groups. @*Results@#Compared to those in the low-VAS group, the spine was significantly extended and bent toward the more painful lower limb side, and the pelvis was significantly anteriorly tilted among individuals in the high-VAS group. @*Conclusions@#Patients with LSS experiencing severe pain in their lower limb tend to keep the spine in a more extended position, bend laterally toward the painful side, and have an anteriorly tilted pelvic posture. The dynamic spinal and pelvic alignment was closely related to the intensity of the lower limb pain.

The patient was a 68-year-old woman who had undergone initial mitral repair at 24 years of age, and had undergone mitral replacement using the Björk-Shiley convexo-concave valve at 30 years of age. She developed exertional dyspnea 38 years after mitral replacement with hemolytic anemia. Precise examination revealed mitral stenosis and perivalvular leak. At the reoperation, severe calcified pannus was found at the ventricular side just beneath the mitral artificial valve, and made stenosis with the inadequate leaflet opening. The mitral valve remnant ring was severely calcified and the sawing ring was detached partially. Repeated valve replacement was successfully done by the reinforcement of the mitral valve ring with xenopericardium.

A 61-year-old woman underwent a regular echocardiography in October 2008 in which a mass of 1 cm in diameter was pointed out in the left ventricle apex. It did not dcrease, in spite of anticoagulation therapy, and therefore we performed surgery. The tumor was confirmed on the septal side of the cardiac apex by intraoperative cholangioscopy, and it was excised through the mitral valve. It was diagnosed as myxoma on immediate intraoperative pathological examination, and we confirmed that there was no tumor remnants on the resected stump histologically. The patient was discharged on the 13th day after the operation and 2 years later she was alive without recurrence of the tumor. This is the 25th case of left ventricular myxoma in Japan. In these reports, an initial resection of the tumor in the left ventricle was performed in 23 cases and the approach methods were described in 20 cases. The evaluation of the resected stump, regardless of remaining tumor, was described in only 3 cases. There were no reports of relapse after the operation. There are many reports which emphasize the usefulness of echocardiography, which is very helpful not only in the diagnosis, but also in periodic evaluations after the operation.

We report a successful staged repair of anomalous origin of right pulmonary artery from the ascending aorta in a neonate. A two-day-old girl, who suffered from severe circulatory failure, was admitted. In spite of all medical treatment, acidosis and systemic hypotension developed. Right pulmonary artery banding was performed in an emergency procedure, resulting in immediate elevation of systemic blood pressure. Definitive operation was subsequently performed on the 48th day after birth. The right pulmonary artery, which was de-banded and divided from aorta, was anastomosed directly to the pulmonary trunk in a side-to-end manner. The postoperative course was uneventful and the pulmonary artery pressure was within the normal range.
