Objectives: Secondary mitral regurgitation (MR) is negatively related to the prognosis of patients with myocardial infarction (MI). Renin-angiotensin system inhibitors (RASI) may favourably affect left ventricular remodelling and reduce afterload and thereby improve prognosis of secondary MR. The aim of this study was to investigate if use of RASI improves prognosis of patients with MI with secondary MR. Methods: A total of 953 patients with MI were enrolled in this study. Long-term prognosis was compared between patients with MI with no/mild MR (n=657), moderate MR (n=196) and severe MR (n=100). Patients with MI with significant (≥moderate) secondary MR were further divided into those treated with and without RASI. Survival and cardiac-event (all-cause death and congestive heart failure)-free survival were compared. Results: Long-term survival was significantly associated with severity of MR (log-rank, p<0.0001). In patients with significant MR (n=296), RASI was used in 130 patients (44%) and not used in 166 patients (56%). Ejection fraction (47.3±12.2 vs 46.6±13.4%, p=NS) and E/e′ (18.4±8.1 vs 16.5±7.0, p=NS) were similar between the two groups. Kaplan-Meier curves for cardiac-event-free survival demonstrated that use of RASI was associated with better survival ( p=0.006) as well as event-free survival ( p=0.02). By univariable and multivariable Cox proportional hazard analysis, age (HR 1.046, 95% CI 1.002 to 1.091, p=0.039) and RASI (HR 0.480, 95% CI 0.231 to 0.995), p=0.048) were independent predictors of cardiac events. Conclusions: Secondary MR affects prognosis in patients with MI. Use of RASI may be associated with better long-term prognosis in patients with MI with significant MR. © 2016, BMJ Publishing Group.

A 76-year-old man with dyspnea and left side chest pain was admitted to our hospital. Chest roentgenogram showed a left side pneumothorax. Chest computed tomography( CT) showed a mass shadow in S3 and a nodular shadow in S10 of left lung. Drainage of the pleural cavity and a trans-bronchial biopsy was performed, and primary lung adenocarcinoma was diagnosed. Abdominal CT showed a left enlarged adrenal gland. Because pneumothorax was resistant to the treatment by closed drainage, a surgical treatment was performed. Since the main tumor of left upper lobe was adjacent to emphysematous bullae, simple bullectomy was not possible. Accordingly, left upper lobectomy, partial resection of left lower lobe and lymph node dissection were performed. Positron emission tomography( PET)-CT after surgery strongly suggested adrenal gland metastasis and the pathological stage was established in combination with the histopathological examination. Appropriate surgical approach must be considered even for case with the advanced lung cancer, like present case. Source

The purpose of this study was to compare the compatibility of ROCEPHINE® Intravenous, the original manufacturer's ceftriaxone sodium preparation for injection, and seven generic versions thereof, with various calcium chloride injection 2%. The influence of calcium ion concentration, storage time and shaking strength on the appearance and quantity of insoluble microparticles in mixed solutions was examined using a light obscuration particle counter. In all products, the observed number of insoluble microparticles was proportional to the calcium ion concentration, storage time and shaking strength after the addition of calcium chloride solution. In several of the generic products, the number of insoluble microparticles was significantly higher than those of the original product, while in others it was lower. We evaluated the quality of the original and 7 generic preparations, measured the content of impurity and pH of the various ceftriaxone solutions, as impurity content and pH of solution are possible factor affecting compatibility. Three impurities were found in all products. The impurity content of several generic products, as estimated from their peak area on high performance liquid chromatography (HPLC), was significantly lower than that of the original product. pH of solution was difference between products. Although it was difficult that impurity and pH of solution verify critical factor affecting compatibility. The results show that there are differences in the appearance of insoluble microparticles between the original product and seven generic products, when calcium chloride injection 2% solution is added to the product. © 2012 The Pharmaceutical Society of Japan.

Background: The usefulness of laparoscopic low anterior resection for middle and lower rectal cancer remains controversial. Methods: Retrospective assessment was performed on 98 patients (51 with middle and 47 with lower rectal cancer) who underwent laparoscopic rectal surgery since 1998. Total mesorectal excision was standard. Cancers were classified as middle or lower rectal based on distance from the distal tumor border to the anal verge (<8 cm or ≥8 cm). Laparoscopic rectal surgery was performed with five or six ports and carbon dioxide pneumoperitoneum. Rectal mobilization was usually done by electrocautery and vessels were sealed with a LigaSureV. Pelvic anatomy was accurately visualized by endoscopic magnification, so autonomic nerves could be preserved. The rectum was mobilized just above the levator muscles. Operative variables and the short- and long-term outcomes were investigated. Results: Five open conversions were required, including three early cases related to rectal transection problems. The other two were for a large tumor and adhesions. Mean operating time was 236 min and blood loss was 147 g. Postoperative complications were 13 cases of anastomotic leakage (13.1%), 6 wound infections (6.1%), 4 cases of anastomotic bleeding (4.0%), and 3 cases of urinary retention (3.0%). Total morbidity was 32.2%, but there were no fatal complications or operative deaths. Mean postoperative period until bowel movement, oral intake, and hospital discharge was 1.6, 1.3, and 19.7 days, respectively. Twelve patients had recurrence: local in 3, lymph node in 2, lung in 5, and liver in 2. The 5-year disease-free/overall survival rates were 82.3/95.7% in stage I, 55.1/72.0% in stage II, and 59.5/80.7% in stage III. Conclusion: Laparoscopic low anterior resection achieves acceptable short- and long-term outcomes. It is a useful option even for advanced lower rectal cancer. © 2009 Springer Science+Business Media, LLC. Source

Background: Corrective osteotomy for malunited diaphyseal forearm fractures remains a challenging procedure. We developed a computer-assisted system for corrective surgery, including a three-dimensional simulation program and a custom-made osteotomy template, and investigated the results of corrective surgery for malunited diaphyseal forearm fractures with use of this technology. Methods: Twenty patients (fifteen male patients and five female patients) with malunited diaphyseal forearm fractures were managed with three-dimensional corrective osteotomy with a custom-made osteotomy template based on computer simulation. We performed osteotomy of both radius and ulna in fourteen patients and osteotomy of the radius alone in six patients. The median age at the time of surgery was eighteen years (range, eleven to forty-three years). The median duration between the time of injury and the time of surgery was thirty-three months (range, five to 384 months). The minimum duration of follow-up was twenty-four months (median, twenty-nine months; range, twenty-four to forty-eight months). To evaluate the results, we compared preoperative and postoperative data from radiographs, forearm motion, grip strength, and pain. Results: The average radiographic deformity angle preoperatively was 21° (range, 12° to 35°) compared with the normal arm; the radiographic deformity angle was improved to 1° (range, 0° to 4°) postoperatively. The distal radioulnar joints of both sides were symmetric on postoperative radiographs regarding the relative lengths of the radius and ulna. In eighteen patients who had a restricted range of forearm motion preoperatively, the mean arc of forearm motion improved from 76° (range, 25° to 160°) preoperatively to 152° (range, 80° to 180°) postoperatively (p < 0.01). However, forearm supination was still restricted by ≥70° in three patients who had been younger than ten years old at the time of the initial injury and who had long-standing malunion for ninety-six months or longer. Painful recurrent dislocation of the distal ulna or radial head resolved or decreased in five patients. Average grip strength improved from 82% to 94% compared with that of the contralateral, normal side. Conclusions: Computer-assisted osteotomy can provide excellent radiographic and clinical outcome for the treatment of malunited diaphyseal forearm fractures. Satisfactory restoration of forearm motion can be achieved even in relatively longstanding cases in adults. Level of Evidence: Therapeutic Level IV.
