Introduction : Recommendations from healthcare providers are considered by vaccinees and their parents when they decide whether to receive an immunization. However, in Japan, the attitudes of primary care physicians toward vaccination are unknown. We assessed some practices and recommendations of, and barriers to, primary care physicians regarding vaccinations in Japan.
Methods : A self-administered questionnaire was mailed (in 2012) to 3000 randomly selected physician-members of the Japan Primary Care Association. Excluded were physicians within two years after graduation, living abroad or retired. We described respondent practices, recommendations, and barriers to the provision of routine and voluntary vaccinations.
Results : The overall response rate was 25.8%. The rates at which physicians gave routine and voluntary vaccines in their own practices were 29.0-91.4% and 15.2-89.5%, respectively. The vaccine recommendation rates for routine and voluntary vaccines were 58.2-70.2% and 14.1-50.9%, respectively. The physicians reported that their barriers to recommendation of routine vaccines were vaccination schedule complexity (32.9%), opinions of vaccinees and parents (28.9%), and vaccine safety (27.7%). They also reported that perceived vaccine safety (62.1%), lack of understanding of vaccine-preventable diseases (55.7%), and complexity of vaccine schedules (44.4%) were reasons given by vaccinees and parents for noncompliance. Physicians' barriers to recommendation of voluntary vaccines were cost (45.3%), safety (35.1%), and lack of information (30.1%). They reported that vaccinees and parents expressed concern about cost (61.8%), safety (51.8%), and lack of vaccine information (50.7%).
Conclusion : We clarified practices, recommendations, and barriers to primary care physicians regarding routine and voluntary vaccination in Japan.

Among 62 patients who underwent hybrid arch TEVAR, which is a combination of supra-aortic bypass and TEVAR to treat arch aneurysm, 5 patients encountered postoperative cerebral infarction. In 2 patients, whose thoracic aorta were extremely shaggy, cerebral infarction were multiple and fatal. Other 3 patients, whose aorta were not shaggy, developed visual disturbance after TEVAR and minor cerebral infarction were detected in the area of vertebral artery. To prevent cerebral infarction after hybrid arch TEVAR, the blood flow from the left subclavian to vertebral artery is considered to be significant.

Destructive aortic valve endocarditis or poor controlled aortitis cause the development of left ventricular-aortic discontinuity. We reported our experience with aortic root replacement for cases of severe aortic annular destruction. Between 1999 and 2006, 9 patients with severe aortic annular destruction underwent aortic root replacement at our institute. There were 8 men and one women with a mean age of 55 years. Seven patients were in New York Heart Association functional class III. Four of 9 patients had native valve endocarditis, 4 had prosthetic valve endocarditis (previous aortic valve replacements in 2, aortic root replacements in 2) and one had active aortitis with a detached mechanical valve. Radical debridement of the infected cavity and necrotic tissue was performed in all cases, followed by reconstruction of the aortic annulus using autologous or xenogenic pericardium in 3 cases. Antibiotic-saturated fibrin glue was applied to the cavity. Aortic root replacement was achieved with a pulmonary autograft (Ross procedure) in 4 and stentless aortic root xenograft in 4. One patient who had advanced liver cirrhosis underwent aortic valve replacement with a stentless xenograft by subcoronary implantation method. No mortality was observed during hospitalization and follow-up. Reoperation within 5 years was not necessary in 66.7% of the patients. Excellent outcome can be achieved by radical exclusion of the abscess cavity and viable pulmonary autograft or stentless aortic root xenograft in patients with severe aortic annular destruction.

Snapping pes syndrome is defined as a snapping sensation in the medial knee caused by pes anserinus and rarely occurs. Snapping pes syndrome after unicompartmental knee arthroplasty (UKA) has not been reported yet. We experienced two cases with this syndrome after UKA. Conservative treatment was effective in one case, while surgical excision of the gracilis tendon was necessary to relieve painful snapping in the other case. The main cause of the first case might be posteromedial overhang of the tibial tray that reached up to 5 mm. The probable cause of the second case was posteromedial overhang of the mobile bearing.

Background: We evaluated the effectiveness of gemcitabine and paclitaxel therapy in patients with metastatic urothelial carcinoma for whom two lines of sequential chemotherapy had been unsuccessful.
Methods: A total number of 105 patients who had previously received first-line chemotherapy consisting of gemcitabine and cisplatin or carboplatin, were treated with second-line gemcitabine and docetaxel therapy between June 2006 and May 2015. Of these patients, 15 with an Eastern Cooperative Oncology Group Performance Status of 0 or 1 were administered gemcitabine and paclitaxel as third-line treatment from 2013 after failure of the second-line therapy. For each 21-day cycle, gemcitabine (1000 mg/m2) was administered on days 1, 8, and 15, and paclitaxel (200 mg/m2) on day 1. Patients were assessed for each cycle and any adverse events were noted. Furthermore, a Short Form Health Survey questionnaire was used to assess each patient’s quality of life.
Results: Third-line gemcitabine and paclitaxel treatment cycles were undertaken for a median of four times (range 2–9). The disease control rate was 80.0%. After second-line gemcitabine and docetaxel therapy was completed, median progression-free survival and median overall survival were determined as 9.8 and 13.0 months, respectively. The only prognostic factor for overall survival, as determined by univariate and multivariate analyses, was third-line gemcitabine and paclitaxel therapy. Neutropenia (66.7%) and thrombocytopenia (53.3%) were noted as the grade 3 treatment-related toxicities. After two cycles of third-line gemcitabine and paclitaxel therapy, the pre- and post-treatment quality of life scores did not differ significantly.
Conclusions: Results demonstrate that third-line combination therapy using gemcitabine and paclitaxel is a feasible option for metastatic urothelial carcinoma patients.

Computed diffusion-weighted MRI is a recently proposed post-processing technique that produces b-value images from diffusion-weighted imaging (DWI), acquired using at least two different b-values. This article presents an argument for computed DWI for prostate cancer by viewing four aspects of DWI: fundamentals, image quality and diagnostic performance, computing procedures, and future uses.

BACKGROUND/AIMS: Venous thromboembolism (VTE) is a major extraintestinal manifestation in inflammatory bowel disease (IBD), regarded as an independent risk factor for VTE according to reports from Western countries. However, the incidence and risk factors of VTE in Asian IBD patients are not fully understood. We aimed to reveal the incidence and risk factors of VTE in Japanese IBD inpatients. METHODS: The incidence of VTE in inpatients with IBD (n=340), gastrointestinal cancers (n=557), and other gastrointestinal diseases (n=569) treated at our hospital from 2009 to 2013 was retrospectively investigated. The characteristics and laboratory data of IBD inpatients with and without VTE were compared in univariate and multivariate analyses. Clinical courses of VTE in IBD were surveyed. RESULTS: VTE was detected in 7.1% of IBD inpatients, significantly higher than in gastrointestinal cancer inpatients (2.5%) and inpatients with other gastrointestinal diseases (0.88%). The incidence of VTE in ulcerative colitis (UC) patients (16.7%) was much higher than that in those with Crohn's disease (3.6%). In the univariate analysis, the risk factors were an older age, central venous catheter, prednisolone, surgery, low serum albumin, high serum C-reactive protein and D-dimer. According to a multivariate analysis, >50 years of age and surgery were the only risk factors. The in-hospital mortality rate of IBD inpatients with VTE was 4.2%. CONCLUSIONS: The incidence of VTE with IBD, especially UC, was found to be high compared with other digestive disease, which was almost equivalent to that of Western countries. The efficacy of prophylaxis needs to be investigated in Asian IBD patients.
