ABSTRACT
[Objective] In the past, we reported results focusing on the immediate effect of psychosocial factors that influence the effects of acupuncture on patients with chronic low back pain. In the present study, we conducted a retrospective analysis of the data before and after four weeks of acupuncture therapy.[Materials and Methods] Fifty-three patients with an initial diagnosis of chronic low back pain who visited the Acupuncture Department of the Center for Integrative Medicine, Tsukuba University of Technology between August and December 2019 and showed baseline lumbar pain intensity by Visual Analogue Scale (VAS) > 30 mm, were subjects of this study. Psychosocial scales viz, Pain Catastrophizing Scale (PCS), Hospital Anxiety and Depression Scale (HADS), Pain Self-Efficacy Questionnaire (PSEQ), social factors (cohabitation family situation, final education, social participation status), Roland-Morris Disability Questionnaire (RDQ), and impression of acupuncture were recorded using a self-administered questionnaire at the first visit and at four weeks after the first acupuncture therapy. Based on VAS, RDQ, and anchor questions about low back pain before and four weeks after the acupuncture therapy, patients were classified into "effective group" and "non-effective group"; then, the logistic regression analysis was performed using this classification as a dependent variable. In addition, r repeated measures analysis of variance (rANOVA) was performed on the data before and after four weeks of acupuncture therapy.[Results and Discussion] The number of patients in the "effective group" and "non-effective group" were 24 and 29, respectively. Among items used as covariates in the logistic regression analysis, the PCS (OR: 0.924, P = 0.037) and age (OR: 0.418, P = 0.005) showed statistical significance. In the rANOVA, all the evaluated items showed statistically significant differences before and after four weeks; only VAS in motion showed a statistically significant difference (P = 0.046) regarding the presence or absence of an immediate effect. Therefore, it was suggested that it is important to focus on psychosocial factors from an early stage of therapy, and to make appropriate evaluations and judgments based on both physical and psychosocial aspects of patients to treat them effectively.
ABSTRACT
Objective: Various psychosocial factors were exploratively investigated in order to specify items that influence on immediate effect of acupuncture among patients with chronic low back pain. Method: Fifty-six outpatients with initial diagnosis of chronic low back pain, visiting the Acupuncture Department of Center for Integrative Medicine, Tsukuba University of Technology between August to December 2019 were included in the study. The baseline lumbar pain intensity of the patients evaluated using the Visual Analogue Scale (VAS) was >30 mm. Psychological scales viz., Pain Catastrophizing Scale (PCS), Hospital Anxiety and Depression Scale (HADS), Pain Self-Efficacy Questionnaire (PSEQ), social factors (cohabitation family situation, final education, social participation status), lumbar dysfunction, and impression on acupuncture were recorded using a self-administered questionnaire during the first visit. Patients showing decreased VAS scale (≦30 mm) after the first acupuncture treatment as well as self-recognition of improvement in pain were classified as “high responders” while the others were treated as “low responders”. Physical and psychosocial factors were exploratively compared between high and low responders and logistic regression analysis of the two groups was performed using a dichotomous dependent variable. Results and Discussion: The number of high and low responders were 22 and 34, respectively. On comparing these groups exploratively, positive (P＝0.001) and negative (P＝0.004) impression on acupuncture were the only items that showed statistical significance. Among items used as covariates in the logistic regression analysis, the PCS (OR: 0.886 (95% CI: 0.808 to 0.971); P＝0.010), positive impression on acupuncture (OR: 5.085 (95% CI: 1.724 to 15.002); P＝0.003), and number of people living together (OR: 0.355 (95% CI: 0.149 to 0.844); P＝0.019) showed statistical significance. Hence, it may be suggested that psychosocial factors influence the immediate effect of acupuncture among patients with chronic low back pain.

ABSTRACT
We report a 25-year-old man with ventricular septal perforation due to blunt chest trauma. He was transferred by ambulance to our hospital following a traffic accident. On admission, he had no cardiac murmur. Two days later, a pansystolic murmur appeared over the left lower sternal border. Doppler echocardiogram revealed a large left-to-right shunt through a ventricular septal perforation. We postponed surgical treatment as long as possible because he also exhibited bronchial bleeding due to a lung contusion. Surgical repair of the ruptured ventricular septum was performed 8 days after the chest trauma, because the pulmonary to systemic flow ratio was elevated to 4.6 and cardiac function had deteriorated. During the operation, the site of the septal perforation was easily detected by epicardial echocardiography. A 4-cm tear in the muscular septum was closed through a right ventriculotomy using a pericardial patch reinforced with a Dacron patch. Postoperative recovery was uneventful with the exception of transient right ventricular failure. There was no residual shunt.
ABSTRACT
A 61-year-old man, who had previously undergone quadruple coronary artery bypass graft surgery, was successfully treated for proximal descending aortic aneurysm using hypothermic circulatory arrest via a left thoracotomy. Preoperative angiograms revealed that the left internal thoracic artery bypass graft to the LAD was patent, and that the aneurysm was located at the descending aorta just distal to the left subclavian artery. Operative procedures were as follows. A left thoracotomy incision was made through the 4th intercostal space. The common femoral artery and vein were cannulated, and the venous cannula was positioned in the right atrium. The patient was cooled by partial cardiopulmonary bypass until the EEG was isoelectric (24°C rectal temperature), and then circulation was arrested. Left ventricular decompression was not performed. After opening of the aneurysm, proximal anastomosis was performed first at the aorta just distal to the left subclavian artery. Another arterial cannula, connected to the Y-shaped arterial line, was inserted into the graft, and perfusion to the brain was restored through this cannula. Distal anastomosis was then completed, and routine cardiopulmonary bypass was reestablished. After the heart was defibrillated, the patient was rewarmed to 34°C before discontinuing the bypass. Circulatory arrest time and total cardiopulmonary bypass time were 17 minutes and 139 minutes, respectively. Postoperative recovery was uneventful.
ABSTRACT
A 66-year-old man with an abdominal aortic aneurysm and coexisting horseshoe kidney is reported. The aneurysm was successfully replaced by a prosthetic graft without resection of the renal isthmus. Because of renal blood supply and location of renal isthmus, aortic reconstruction presents a significant technical problem. Preservation of multiple renal arteries may be facilitated by preoperative aortography, and retraction of the renal isthmus offers good operative exposure.
ABSTRACT
We have treated 12 popliteal aneurysms in ten patients from 1965 to 1989. There were seven men and three women, aged 34 to 78 years (mean, 61.5 years). Two patients had bilateral aneurysms. The chief complaint was pain at rest, claudication, coldness, etc. in eight patients, a mass or induration at the popliteus in two patients, peroneal nerve or vein compression in one patient each. Angiography showed thrombotic obstruction in six legs and distal occlusion in one leg. Ten of aneurysms of eight patients were treated surgically. In two patients, the operation was done on emergency basis. Amputation was not necessary in any case. The operative method was usually excision of the aneurysm. Reconstruction was made with artificial vessels in the first patient who underwent bilateral aneurysm surgery. Auto-saphenous vein were used in other seven patients. All vein grafts were patent at follow-up (mean follow-up period, 4 years and 3 months). Arteriosclerotic changes were histologically observed in all aneurysms. Complications such as thrombotic obstruction and distal occulsion are frequent and leg amputation is necessary in some cases. Arterial reconstruction with an auto-saphenous vein is necessary for popliteal aneurysm.
ABSTRACT
We did a retrospective review of 83 femoropopliteal bypasses with grafting of saphenous vein performed for two groups of limbs: those with arteriosclerosis obliterans (<i>n</i>=71) and thromboangiitis obliterans (<i>n</i>=12) over the past 15 years. The purpose of the study is to assess factors that influence long-term graft patency. We also examined methods used for reoperation. After a mean follow-up of 35 months (ranges, 1-164), the cumulative patency rate was 79% at 5 years and again 79% at 8 years, which was better than the patency of PTFE grafts or other prosthetics reported by other authors. The two groups were compared for the severity of ischemia, condition of the outflow tract, and whether anastomosis was above or below the knee. These factors were different between the two groups, but the difference in patency was statistically not significant. Two reoperations for claudication were needed. One was carried out with use of the bilateral saphenous veins from below the portions used earlier. The other was done for obstruction of a PTFE graft; anastomosis was done at the mid portion with the use of Vitagraft.
