Our school of medicine began a new curriculum for medical students in April of 1999. In their final year medical students are allowed to schedule a 3-month clinical clerkship. This clerkship gives the students three 4-week periods to do rotations in their areas of interest. Our clinics have had a hard time finding the time to teach students evidence-based medicine (EBM) owing to their clinical workloads. Even when the divisions want to teach EBM there are few resources available for the students. Therefore, students are sometimes unable to receive adequate training in EBM. With the introduction of the new curriculum the Department of Hygiene and Public Health thought that the clinical clerkship program offered a good opportunity to teach students EBM with a one-to-one student-teacher relationship. We report here on our preliminary program that uses a scenario approach to EBM education. We determined the students' level of development by studying the detailed progress reports written by their teachers. The students were found to understand EBM when presented with its basic concepts which are then used in multiple discussions. Students will continue to use self-directed learning throughout their careers if they learn to think using EBM early in their training and practice it during their residency. We also show here a worksheet based on the Journal of the American Medical Association User's Guide series to use systematic EBM in daily clinics. Our program is just one of several methods we hope to develop to educate medical students in EBM.

Although the combined administration of glycyrrhizin (SNMC) and ursodeoxycholic acid (UDCA) is usually used for intractable patients with active HCV-associated chronic hepatitis (HCV-CH) or cirrhosis (LC), there are many cases that do not respond to this combination therapy. In this study, we examined the effects of adding Juzen-taiho-to (TJ-48) to lower the serum alanine aminotransferase (s-ALT=s-GPT) levels in such cases. Methods: The average s-ALT levels for 6 months were compared before and after 7.5g of Juzen-taiho-to was added to the combined therapy of SNMC and UDCA for 9 HCV-CH and 12 HCV-LC patients. In some cases, the effectiveness of the therapy over 12 months was also evaluated. Results: In the HCV-CH cases s-ALT levels were significantly decreased in 3 of 9 (33%) cases in 6 months (about 30 INU in average). In the HCV-LC cases, s-ALT levels were significantly decreased in 5 of 12 (42%) cases in 6 months (more than 40 INU in average). There were some patients whose s-ALT levels decreased significantly after 6 months. As to the improvement of clinical symptoms, general fatigability improved in 12 out of 20 cases (60%) and anorexia improved in 10 out of 19 cases (53%). Conclusions: Juzen-taiho-to (TJ-48, 7.5g daily) added to the combined therapy of SNMC and UDCA may be an effective therapy for intractable cases of active HCV-CH or LC.

BACKGROUND: physicians' awareness regarding evidence-based medicine (EBM), clinical practice guidelines, and clinical information resources were rarely examined in Japan. We need to know them prior to the initiation of the Medical Information Network Distribution Service (Minds) by the Japan Council for Quality Health Care (JCQHC) .
METHODS: A total of 10, 000 directors/owners of private clinics (CDs: clinic physicians) affiliated with the Japan Medical Association (JMA) and 8682 physicians working for hospitals certified by the JCQHC (HDs: hospital physicians) were randomly selected and surveyed by a mailed questionnaire.
RESULTS: The response rate to the questionnaire was 18.7% (n=1865) among CDs and 67.8% (n=5885) among HDs. The percentage of respondents who uses internet was 39.9% among CDs and 69.3% among HDs. The information resource most commonly used by all respondents was medical journals, followed by textbooks. The percentage of respondents who used medical literature database was 10.8% among CDs and 49.7% among HDs, respectively. Approximately 80% of all respondents approved implementing EBM in daily practice. Fifty percent of all respondents indicated to have used clinical practice guidelines, and 90% of all the guideline users replied that clinical practice guidelines are useful tools for clinical decision-making. Over half of HDs required to access to the abstracts of the literature cited in the guidelines.
CONCLUSIONS: Many physicians who responded to the survey acknowledged that EBM will contribute to improving the quality of medical services. They are positive in using clinical practice guidelines that include a series of recommendations proposed by specialists in the relevant field (s) in accordance to the reviewed evidence.

BACKGROUND: The purpose of our study was to compare the characteristics of medical practitioners who prefer using the Internet as their information resource and those who prefer using printed materials.
METHODS: From December 2002 to January 2003, a non-anonymous questionnaire was sent out by post to members of the Japanese Medical Association (JMA) and physicians working in hospitals. Contributing factors were examined by using logistic regression analysis.
RESULTS: The response rates for the questionnaires were 18.7% (n=1868) for JMA physicians and 68.0% (n=5901) for hospital physicians. Factors associated with the preference for using the Internet were: ‘younger age’; ‘use of the Internet to solve clinical problems and uncertainties’; ‘use of personal computers at work’; and, ‘use of personal computers at home’.
CONCLUSION: The results of this study show that, although some younger physicians prefer printed materials, providing medical information via the Internet is better suited for younger physicians who are making full use of computers. In contrast, older physicians prefer printed materials because they tend to be less familiar with using computers and may have limited accessibility to the Internet. Therefore, using both the Internet and printed materials to provide medical information is necessary to meet the needs of the larger physician population.

A 49-year-old man who had no history of cardiac disease or intravenous drug abuse was referred to our hospital complaining of fever despite antibiotic chemotherapy. Blood culture was positive for Streptococcus agalactiae, and transesophageal echocardiography revealed vegetation attached to the tricuspid valve and moderate tricuspid regurgitation. Two-thirds of the anterior leaflet and a part of the posterior leaflet of the tricuspid valve were excised with the vegetation, and the remaining anterior leaflet was sutured to the posterior leaflet after annular plication. DeVega's annuloplasty was added to a diameter of two fingers. Following this procedure tricuspid regurgitation was minimal.

This study examined the effectiveness of a communication program in undergraduate medical education in improving communication in physicians' clinical practice. The effectiveness of the program was assessed with a mail survey using self-rated questionnaires 9 years later. Ninety participants were follwed up in late 1994; 57.8% of them replied to the questionnaire. Of the respondents, 60% replied that programs concerned with active listening and role-playing had benefits on communicating with patients and families. In addition, 40% of respondents answered that case studies aimed at teaching comprehensive medicine with the team approach was effective in improving communication with co-medical staff. These results suggest that the communication program in undergraduate medical education is effective in improving clinical communication in clinical practice when students are highly motivated.

Sixteen cases of malignant soft tissue sarcoma (STS; 10 canines and six felines) were treated with a novel triple therapy that combined photodynamic therapy, hyperthermia using indocyanine green with a broadband light source, and local chemotherapy after surgical tumor resection. This triple therapy was called photodynamic hyperthermal chemotherapy (PHCT). In all cases, the surgical margin was insufficient. In one feline case, PHCT was performed without surgical resection. PHCT was performed over an interval of 1 to 2 weeks and was repeated three to 21 times. No severe side effects, including severe skin burns, necrosis, or skin suture rupture, were observed in any of the animals. No disease recurrence was observed in seven out of 10 (70.0%) dogs and three out of six (50.0%) cats over the follow-up periods ranging from 238 to 1901 days. These results suggest that PHCT decreases the risk of STS recurrence. PHCT should therefore be considered an adjuvant therapy for treating companion animals with STS in veterinary medicine.

OBJECTIVE: Electroconvulsive therapy (ECT) has proven to be effective in treatment-resistant depression (TRD). In recent reports, 70% to 90% of patients with TRD responded to ECT. However, post-ECT relapse is a significant problem. There are no studies investigating risk factors associated with reintroducing ECT in depressive patients after remission previously achieved with former ECT. The aim of the present study is to examine such risk factors using a sample of TRD patients. METHODS: We conducted a chart review to examine patient outcomes and adverse events over short- and long-term periods. Forty-two patients met the criteria for major depressive disorder. RESULTS: The response rate was 85.7% (36/42). There were no significant differences in the baseline characteristics of patients exhibiting remission, response or non-response. The rate of adverse events was 21.4% (9/42). Among 34 patients who were available for follow-up, 18 patients relapsed (relapse rate, 52.9%), and 6 patients were reintroduced to ECT. The patients' age and age of onset were significantly higher in the re-ECT group than non re-ECT group. CONCLUSION: Our results suggest that older age and older age of onset might be considered for requirement of re-ECT after remission previously achieved with former ECT.

Background/Aims:
The optimal length of the uncovered portion of partially covered self-expandable metal stents (PCSEMSs) used in endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) remains unclear. This study investigated the safety and efficacy of PCSEMSs with different uncovered lengths, with a focus on stent migration and time to recurrent biliary obstruction (RBO).
Methods:
Outcomes of patients undergoing EUS-HGS using PCSEMSs with 5-mm and 20-mm uncovered portions at our institution from January 2016 to December 2021 were compared.
Results:
Sixty-two patients underwent EUS-HGS using PCSEMS (5/20-mm uncovered portions: 32/30). Stent migration occurred only in the 5-mm group. There were no differences in RBO rates (28.1% vs. 40.0%) or median time to RBO (6.8 vs. 7.1 months) between the two groups. Median overall survival (OS) was longer in the 20-mm group (3.1 vs. 4.9 months, p=0.037) due to the higher number of patients that resumed chemotherapy after EUS-HGS (56.7% vs. 28.1%, p=0.029). Good performance status, absence of hepatic metastases, and chemotherapy after EUS-HGS were independent predictors of longer OS.
Conclusions
No migration was observed in patients treated with PCSEMS with 20-mm uncovered portions. Patients treated with PCSEMS with 20-mm uncovered portions performed at least as well as those treated with 5-mm uncovered portions in all material respects.

Purpose:
Accelerated atherosclerosis is a major complication in patients with end-stage renal disease and it plays an important role in the pathogenesis of erectile dysfunction (ED). However, the association between aortic calcification burden and the severity of ED remains unclear. The aim of the present study was to investigate this association in men undergoing dialysis.
Materials and Methods:
This cross-sectional study included 71 men undergoing peritoneal dialysis and/or hemodialysis between July 2016 and May 2018 at Mutsu General Hospital. ED was assessed with the Sexual Health Inventory for Men (SHIM). Patients were divided into the mild/moderate (SHIM score ≥8) and severe ED groups (SHIM score ≤7). Aortic calcification index (ACI) was examined as a clinical indicator of abdominal aortic calcification. Multivariable logistic regression analysis was performed to identify the significant factors associated with severe ED.
Results:
The median age of the study participants was 64 years; all had ED, with 64.8% having severe ED. In the multivariable analyses, a slight association was observed between ankle-brachial index and severe ED (odds ratio [OR], 0.058; p=0.072), whereas ACI was significantly associated with severe ED (OR, 1.022; p=0.022).
Conclusions
Aortic calcification burden was independently associated with severe ED.
