We report a case of type A dissecting aneurysm occurring after aortic valve replacement (AVR). The patient was a 67-year-old man with a history of AVR 4 years previously. Preoperative CT scan revealed a type A dissecting aneurysm 10cm in diameter, close to the sternum. Under preparation for selective cerebral perfusion (SCP), re-do median sternotomy was safely performed using partial extracorporeal circulation (ECC) via a femoral artery and vein. Because of severe adhesion in the upper part of the ascending aorta and aortic arch, a graft replacement of the ascending aorta was impossible. Under SCP via bilateral common carotid arteries exposed in the neck, the entry of the dissection, which was located in the previous aortotomy line, was closed with an ePTFE patch. SCP via bilateral common carotid arteries exposed in the neck appeared to be very useful and safe for such patients at risk for injury to the aorta during re-do median sternotomy and with severe adhesion, which made it difficult to establish SCP via the usual operative field. Although graft replacement is the standard operation for the treatment of the ascending aortic dissection, patch closure of the entry should be considered as a second-choice method in some case.

We treated one rheumatoid arthritis (RA) patient with Toki-shakuyaku-san-ka-bushi. A 51-year-old woman was diagnosed as RA in another hospital and was treated with salazosulfapyridine (SASP) and methotrexate (MTX). She was living a restricted daily life while taking MTX. She had to lie down for almost 48 hours after taking MTX once a week because of general fatigue. She was also suffering from depression. After the administration of Toki-shakuyaku-san-ka-bushi, her malaise after taking MTX and her depressive-mood disappeared. Her quality of life improved measurably.

We show here that stress proteins (Mr 70K, 85K and 100K) were induced by both electroacupuncture and moxibustion.
Rats (Wister strain, male, 250g) were cauterized with moxa on the hip, and the subcutaneous and intramuscular temperatures of the hip were kept at 45°C and at 39-40°C for 15 minutes. While, another group of rats were electrically stimulated for 15min inserting acupuncture needles as electrodes into the muscle of the hips in the depth of 1cm and using current pulse acupuncture system (5Hz, 3-5mA). Both groups of rats were sacrificed under deep anesthesia and the muscular tissues were excised 3 hours after the stimulations. The proteins extracted from the homogenized and centrifuged tissues in the two groups of rats and control rats were analyzed by two-dimensional gel electrophoreses. The heat shock proteins with molecular weight of 70000 (Mr 70K, hsp 70), 85000 (Mr 85K, hsp 85) and 100000 (Mr 100K, hsp 100) were detected in the rats stimulated by moxibustion. The stress proteins of molecular mass 70000, 85000 and 100000 similar to hsps induced by moxibustion were found in the rats stimulated by electroacupuncture.

Objective: There are few reports of the long-term outcomes of elderlypatients with prostate cancer. We analyzed data from our institution from the past 12years, including the patient history, treatment methods, and prognosis of patients withprostate cancer aged 80 years or more.
Patients and Methods: A total of 179 cases of prostate cancer in patientsaged 80 years or more were retrospectively evaluated. We divided them chronologically intogroups A, B, C, and D: Group A included 40 cases from 2002–2004; Group B, 48 cases from2005–2007; Group C, 46 cases from 2008–2010; and Group D, 45 cases from 2011–2013.
Results: Sixty-one (30%) patients changed treatment course. Interestingly,no cancer deaths occurred in the patients who changed treatment course. Although 14 (7.8%)cancer deaths occurred (A: B: C: D = 4: 4: 6: 0, respectively), all occurred in 2011 orlater.
Conclusion: In our study, over 50 patients who underwent treatment survivedfor 5 years or more. By treating prostate cancer in elderly patients when appropriate, wecan lower the mortality rate due to prostate cancer. Our results support the activetreatment of prostate cancer in elderly patients.

Although there are a number of reported cases of increased cerebral blood flow during exercise, there are no reports on the relation between changes of blood flow during exercise and attentional function. The purpose of this study is to clarify the relation between changes of blood flow during exercise with AT intensity and attentional function, using near-infrared spectral analysis. The subjects were 10 healthy males. The research protocol was to conduct steady load exercise. We randomly conducted two invention trials: 1) an exercise/task trial in which a trail making test (TMT) was performed as an attentional assignment during steady load exercise, and 2) a rest/task trial in which TMT was performed during rest as a control. As a result, we observed the following: increase of oxy-Hb in the prefrontal cortex during AT exercise, the significant shortening of TMT during exercise from 69.1±10.2 seconds to63.2±7.2seconds, and, with further control, that the more oxy-Hb rises, the more TMT time is shortened. From these results, it is suggested that 10 minutes of exercise would improve attentional function, and furthermore, there is a possibility that increased cerebral blood flow may be involved with the improvement of attentional function.

Enterovesical fistula is a relatively uncommon complication of colorectal and pelvic malignancies, diverticulitis, inflammatory bowel disease, radiotherapy, and trauma in Asian countries. A case of vesico-ileosigmoidal fistula and a literature review of this disease in Japan are presented. A 70-yr-old male was referred with complaints of urinary pain and pneumaturia. On admission, urinary tract infection and pneumaturia were presented. A barium enema demonstrated multiple diverticulum in his sigmoid colon and the passage of contrast medium into the bladder and ileum. Under the diagnosis of vesico-ileosigmoidal fistula due to suspected diverticulitis of the sigmoid colon, sigmoidectomy and partial resection of the ileum with partial cystectomy were performed. The histopathology revealed diverticulosis of the sigmoid colon with diverticulitis and development of a vesico-ileosigmoidal fistula. No malignant findings were observed. Until the year 2000, a total of 173 cases of vesico-sigmoidal fistula caused by diverticulitis had been reported in Japan. Pneumaturia and fecaluria are the most common types, presenting symptoms in 63% of the cases. Computed tomography, with a sensitivity of 40% to 100%, is the most commonly used diagnostic study. For patients with vesico-sigmoidal fistula, resection of the diseased sigmoid colon and partial cystectomy with primary anastomosis are the safest and most acceptable procedures, leading to the best results.

The purpose of this study was to evaluate the effect of keishibukuryogan (KB) against the cognitive symptoms associated with silent brain infarction in a prospective cohort study. The subjects were 93 patients with silent brain infarcts who visited the Department of Japanese Oriental Medicine, University of Toyama, and its allied hospitals. They consisted of 24 males and 69 females, mean age (± S.E.) 70.0±0.8.Group SK (n=51) consisted of patients who used KB extract for more than6months per year. Group SC (n=42) consisted of patients who did not use Kampo formulas. The NS group (n=44) consisted of elderly subjects who had no silent brain infarction, 21 males and 23 females, with a mean age (± S.E.) of 70.7±0.7 years. Among the three groups, the revised version of Hasegawa's dementia scale, apathy scale and self-rating depression scale were compared between the study start and after three years. In the SK and SC groups, these scores, and the subjective symptom levels (head heaviness, headache, dizziness or vertigo, stiff shoulder) were also studied. The results showed that the self-rating depression scales at study start for the SK and SC groups were significantly higher compared to the NS group. In spite of the scores for the NS group increasing after three years, the SK group scores were significantly decreased compared to the SC and NS groups. KB was effective against head heaviness, which often complicates silent brain infarction. In the above mentioned, KB was effective in treating cognitive disorders and subjective symptoms related to silent brain infarction.

Methods:
We reviewed 125 patients (79 men and 46 women) who had lumbar spinous process splitting laminectomy (LSPSL) for LSS. We assessed the following clinical information: Japanese Orthopedic Association (JOA) score; numerical rating scale (NRS) for low back pain (LBP), leg pain, and leg numbness; Zurich Claudication Questionnaire; JOA Back Pain Evaluation Questionnaire; Roland- Morris Disability Questionnaire (RMDQ); and Short Form 8 (SF-8) as HRQOL. We compared the HRQOLs of men and women pre- and postoperatively.
Results:
Although the preoperative NRS results for LBP were significantly higher in women (p <0.05), there were no significant differences in clinical outcomes between men and women postoperatively. For HRQOL, the RMDQ scores were significantly worse in women preoperatively (p <0.05), but no significant differences were found postoperatively between men and women. Similarly, the SF-8 mental health score was also significantly lower in women preoperatively (p <0.05), but no significant differences were noted between the two groups postoperatively.
Conclusions
LSPSL greatly reduced LBP, leg pain, and leg numbness in both genders. There were limited differences in pain and several HRQOL questionnaire responses between men and women after surgery. We found that women had greater sensitivity to and/or lower tolerance for pain than men, which led to lower HRQOL mental health scores preoperatively.

Objectives: Gauze remnants form gauzeomas after surgery, if infection has not occurred. We present a case of gauzeoma diagnosed after surgery.Patient: A 72-year-old man noticed a mass in his lower abdomen. He had undergone surgery for left inguinal hernia 21 years ago. A retroperitoneal mass was found on computed tomography (CT) and magnetic resonance imaging (MRI), and he was then referred to our hospital. A detailed abdominal ultrasonography, CT, and MRI revealed a cystic mass with a bulkhead-like structure near the bladder. These findings indicated the possibility of a malignant cyst; hence, an open surgery was performed to excise the mass. Macroscopically, the specimen was clearly bound, covered with a capsule, and filled with pus and had a gauze inside.Results: Based on the patient history and position of the mass, it was diagnosed as gauzeoma, which had strayed into the retroperitoneal cavity during the surgery for inguinal hernia.Conclusion: The imaging findings of gauzeoma are diverse; hence, it is often difficult to diagnose without surgery. However, gauzeoma can be lethal if the cystic mass is infected; thus, it is important to diagnose it correctly.
