We have managed information on adverse drug reaction using the clinical records to obtain data from within our hospital and using Medicine-Pocketbooks to obtain data outside our hospital.  Our system for management of side effect information does not require the development of a separate specialized system.  Our method of collecting side effect information was changed in April 2007.  Therefore, we evaluated our present method of collecting information on side effects by comparing the method used before the change with the new method.  The amount of side effect information collected has clearly increased since April 2007.  Although the amount of data collected directly from doctors has increased eight-fold, the amount collected from other data sources has hardly changed.  Side effect symptoms have hardly changed, with skin symptoms being the most frequent side effect.  Suspected drugs have also hardly changed, with antibiotics being the most frequently suspected drugs.  In addition, we conducted questionnaire surveys on the use of Medicine-Pocketbooks by patients who registered side effect information at our hospital to determine whether Medicine-Pocketbooks were being used effectively as a tool for the management of side effect information.  Among patients who registered their side effect information at our hospital, 76% also presented their Medicine-Pocketbooks to other medical institutions.  In addition, all patients received a change in prescription or were questioned about their side effect information when they presented their Medicine-Pocketbooks.  Our present method of collecting side effect information is considered appropriate since there was an increase in the amount of side effect information collected from doctors.  Medicine-Pocketbooks have also been effectively used as a tool for managing side effect information.

Although sequential bypass with in situ arterial conduits (the left and right internal thoracic arteries; LITA and RITA, the right gastroepiploic artery; GEA) in coronary artery bypass grafting (CABG) is technically demanding, it is one of the most important procedures using a limited number of in situ arterial conduits to revascularize a wide area. In this report, we retrospectively investigated the clinical outcome of CABG with 4 or more distal anastomoses using only in situ arterial conduits. From December 1990 to May 1999, 62 patients underwent CABG with in situ arterial conduits, with at least one sequential bypass. There were 59 men and 3 women patients with mean age of 59.6 years (41 to 82 years). Mean postoperative follow-up period was 32 months (1 to 101 months). The total number of distal anastomoses was 4 (1 sequential bypass) in 54 patients, 4 (2 sequential bypasses) in 6 patients, 5 (1 sequential bypass) in 1 patient and 6 (3 sequential bypasses) in 1 patient. There were 5 emergency operations (8%), 37 patients (60%) had a history of myocardial infarction, 30 patients (48%) had diabetes mellitus and 6 patients (10%) had chronic renal failure and were on hemodialysis. Left ventricular ejection fraction was 40% or less in 15 patients (24%). There were no early deaths. Angiographic patency was satisfactory for each graft (sequential: individual, LITA 96.7%: 100%, RITA 100%: 100%, GEA 89.5%: 97.4%). Patency of a distal anastomoses of GEA was rather poorer than that of proximal (p=0.03). Three patients died during the follow-up period (all of them due to malignancy). The 5-year actuarial survival and cardiac event-free rate was 94.6% and 87.2%, respectively. In conclusion, although an indication of GEA sequential grafting needs further study, in situ arterial grafting with at least one sequential arterial conduit was associated with excellent results and achieved more complete revascularization with exclusive use of in situ arterial conduits in patients with diffuse coronary artery disease.

BACKGROUND: We investigated whether the calcar femorale, a cortical septum in the region of the lesser trochanter of the femur, correlates with results of femoral stem implantation in patients with osteoarthritis of the hip secondary to developmental dysplasia using computed tomography. METHODS: This retrospective study included 277 hips (41 males and 236 females; age, 37 to 92 years) of patients who had presented to Okayama Medical Center with hip pain. Of these, a total of 219 hips (31 males and 188 females) had previously undergone total hip arthroplasty. According to the Crowe classification, 147 hips were classified as Crowe grade I, 72 hips as Crowe grade II–IV, and 58 hips as normal. RESULTS: The calcar femorale was identified in 267 hips (96.4%). The calcar femorale was significantly shorter and more anteverted in Crowe grade II–IV hips than in Crowe grade I or normal hips. Significant differences in the shape of the calcar femorale were found according to the severity of hip deformity. Three stem designs were analyzed: single-wedge (59 hips), double-wedge metaphyseal filling (147 hips), and modular (13 hips). Single-wedge stems were inserted more parallel to the calcar femorale rather than femoral neck anteversion, while other types of stems scraped the calcar femorale. CONCLUSIONS: The angle of the calcar femorale differs according to the severity of hip deformity, and the calcar femorale might thus serve as a more useful reference for stem insertion than femoral neck anteversion in total hip arthroplasty using a single-wedge stem.

STUDY DESIGN: Retrospective case series. PURPOSE: To investigate the oncological outcomes, including distant relapse, after en bloc spondylectomy (EBS) for spinal metastases in patients with a minimum of 2-year follow-up. OVERVIEW OF LITERATURE: Although EBS has been reported to be locally curative and extend survival in select patients with spinal metastases, detailed reports regarding the control of distant relapse after EBS are lacking. METHODS: We conducted a retrospective review of 18 consecutive patients (median age at EBS, 62 years; range, 40–77 years) who underwent EBS for spinal metastases between 1991 and 2015. The primary cancer sites included the kidney (n=7), thyroid (n=4), liver (n=3), and other locations (n=4). Survival rates were estimated using the Kaplan–Meier method, and groups were compared using the log-rank method. RESULTS: The median operative time and intraoperative blood loss were 767.5 minutes and 2,375 g, respectively. Twelve patients (66.7%) experienced perioperative complications. Five patients (27.8%) experienced local recurrence of the tumor at a median of 12.5 months after EBS, four of which had a positive resection margin status. Thirteen patients (72.2%) experienced distant relapse at a median of 21 months after EBS. The estimated median survival period after distant relapse was 20 months (95% confidence interval, 0.71–39.29 months). No association was found between resection margin status and distant relapse. Overall, the 2-year, 5-year, and 10-year survival rates after EBS were 72.2%, 48.8%, and 27.1%, respectively. Importantly, the era in which EBS was performed did not impact the oncological outcomes. CONCLUSIONS: Our results suggest that EBS by itself, even if margin-free, cannot prevent further dissemination, which occurred in >70% of patients at a median of 21 months after EBS. These results should be considered and conveyed to patients for clinical decision-making.
