Purpose: Does longer study time motivate students to learn and make them feel a sense of accomplishment? Whilst “Human Biology,” one of the required courses in the first year of the medical school, was in need of a total course design reformation to make a shift from teaching to learning, it was necessary to examine whether longer study time is effective for better learning outcomes.　Methods: To get students to learn outside of class, we flipped the course. Since the scores from weekly quizzes, which are held at the beginning of every class, and mid-term and final exams were returned to the students, fully calculated and strictly applied to their grades, students became motivated to study before class. During class time, lessons were taught in the active learning style. We used covariance structure analysis to examine the relationship between the out of class learning design, the syllabus reformation, students’ learning attitudes in the class, and their sense of accomplishment.　Results: Study time outside of class increased from 4 hours per week in 2013 to 10 hours per week in 2016, and the students became more satisfied with the course. Our analysis shows that this well-structured syllabus and designing of lessons made the students study more both inside and outside of class, and allowed students to achieve the higher goals of the course.　Conclusion: Designing out of class learning and incorporating it well with assessment resulted in longer study time and a stronger sense of accomplishment.

Anomalous origin of the coronary artery from the pulmonary artery (ACAPA) is a rare congenital heart disease. A woman in her 60s was diagnosed as ARCAPA during examination for angina. A magnetic resonance image showed myocardial ischemia in a small area of the right coronary artery (RCA) and left anterior descending artery. Reimplantation of the RCA to the ascending aorta and patch plasty of the pulmonary artery were performed. Repositioning of the RCA orientation was necessary for relief of the kinking. The postoperative course was uneventful. She is now free from angina 15 months after surgery.

Background : Persistent endoleak is a major cause of aneurysmal enlargement or rupture after endovascular aneurysm repair (EVAR). Although several reports have described ligation of lumbar arteries and stent graft-conserving aneurysmorrhaphy as useful strategies, treatment for type II endoleak after EVAR is controversial. Objectives : We investigated the early results in 5 patients who underwent ligation of lumbar arteries and stent graft-conserving aneurysmorrhaphy for type II endoleak. Methods : A>10 mm increase in aneurysm diameter after primary EVAR or a maximum diameter>65 mm serve as indications for intervention for type II endoleak. Under general anesthesia, following transperitoneal exposure of the abdominal aorta, the infrarenal aorta was banded using a tape at the proximal landing zone. After the aorta was opened without clamping, the lumbar arteries were ligated, and a stent graft-conserving aneurysmorrhaphy was performed. Results : The mean interval from the primary EVAR was 47±17 months. The mean operation time was 215±76 min. Blood transfusion was necessary in 4 patients (estimated blood loss 1,260±710 ml). No in-hospital deaths were observed, and the mean postoperative hospital stay was 26±20 days. One patient developed aspiration pneumonia and 1 developed surgical site infection post-surgery. The diameter of the aneurysm changed from 68±8 to 47±5 mm during hospitalization and decreased further to 36±7 mm at the last follow-up. Conclusions : The early results of ligation of lumbar arteries and stent graft-conserving aneurysmorrhaphy were favorable. Although this strategy could be useful for aneurysmal dilatation secondary to persistent type II endoleak after EVAR, the indications for this approach should be determined following careful evaluation of the patient's status considering the invasiveness of the procedure.

Objective: Caffeine may cause dependence and sleep disturbance, and interact with psychotropic drugs.　Therefore, the caffeine intake of patients with mental disorders should be monitored.　However, in Japan, there is no report on the effects of caffeine in mental disease patients or on their caffeine intake.　Therefore, we conducted a questionnaire survey to clarify the perception of caffeine for psychiatric outpatients.Methods: We conducted an anonymous survey on caffeine recognition for outpatients at 8 medical institutions that advocate psychiatry.Results: We collected questionnaires from 180 people.　The knowledge of foods containing caffeine tended to be high in those who had a positive attitude toward caffeine.　More than 90% of those surveyed knew that coffee contains caffeine, but cocoa and jasmine tea were recognized by less than 25%.　Of those surveyed, 39.4% consumed caffeine‐containing beverages at night.　In addition, the rate of consumption of caffeine‐containing beverages tended to be higher at night because they had a positive attitude toward caffeine.Conclusion: The knowledge and intake situation of caffeine by patients with mental disorders differed depending on their interests and way of thinking about caffeine.　As caffeine intake may influence psychiatric treatment, correct knowledge regarding caffeine is important.

Surgical cases for pulmonary artery aneurysm after palliative operation for congenital heart disease are rare. A man in his 40s underwent Waterston operation (side-side anastomosis of the ascending aorta and right pulmonary artery) for pulmonary atresia and ventricular septal defect at the age of one. Medical follow-up was continued at a local clinic without definitive repair. He had complained of exertional dyspnea and cough for one month. CT scan on admission showed a large right pulmonary artery aneurysm and atelectasis of the right lung. An urgent operation was planned for the huge pulmonary artery aneurysm. Under cardiac arrest, the proximal end-to-side anastomosis to the aorta was conducted using a Y-shaped vascular prosthesis at the previous Waterston anastomosis. The peripheral pulmonary arteries were reconstructed by inclusion technique. Percutaneous cardiopulmonary support was necessary for one day after operation due to unstable hemodynamics. He was extubated on postoperative day (POD) 4 and transferred to our general ward on POD 5. He was discharged home on POD 38. He is now free from heart failure symptoms and recurrence of aneurysm one year after surgery. Careful follow-up is necessary for the dilatation of the pulmonary artery and aortic root. A definitive operation—Rastelli and closure of the ventricular septal defect—may be considered in the future if the pulmonary artery resistance is suitable for the repair.

BACKGROUND/AIMS: In clinical practice, colonoscopy has been regarded as the gold standard for the evaluation of disease severity as well as mucosal healing in ulcerative colitis (UC). Some activity indices incorporating patient symptoms as parameters have been shown to reflect the endoscopic activity of UC. The aim of this study was to examine whether self-reported symptoms with visual analog scales (VAS) can predict endoscopic activity. METHODS: A cross-sectional study of 150 UC patients who underwent colonoscopy with submission of VAS scores of 4 symptoms: general condition, bloody stools, stool form, and abdominal pain (0: no symptoms, 10: the most severe symptoms). Each VAS score was compared with colonoscopic activity assessed with the Mayo endoscopic subscore (MES). RESULTS: All VAS scores were significantly correlated with the endoscopic severity (Spearman correlation coefficients of general condition, bloody stools, stool form, and abdominal pain: 0.63, 0.64, 0.58, and 0.43, respectively). Mucosal healing defined as MES 0 alone was predicted by VAS score < 1.5 on general condition or 0 on bloody stools with sensitivity of 0.84 and 0.76 and specificity of 0.66 and 0.76, respectively. Additionally, VAS score < 2.5 on stool form predicted active lesions in distal colorectum alone with sensitivity of 0.67 and specificity of 0.66, suggesting that this item could predict the indication of topical therapy. CONCLUSIONS: Self-reported VAS scores on symptoms were correlated with endoscopic activity of UC. To clarify the relationship between VAS and mucosal healing, further validation studies are needed.

OBJECTIVE: To retrospectively evaluate relative enhancement (RE) in the hepatobiliary phase of gadoxetic acid disodium-enhanced magnetic resonance (MR) imaging as a preoperative estimation of future remnant liver (FRL) function in a patients who underwent portal vein embolization (PVE). MATERIALS AND METHODS: In 53 patients, the correlation between the indocyanine green clearance (ICG-K) and RE imaging was analyzed before hepatectomy (first analysis). Twenty-three of the 53 patients underwent PVE followed by a repeat RE imaging and ICG test before an extended hepatectomy and their results were further analyzed (second analysis). Whole liver function and FRL function were calculated on the MR imaging as follows: RE x total liver volume (RE Index) and FRL-RE x FRL volume (Rem RE Index), respectively. Regarding clinical outcome, posthepatectomy liver failure (PHLF) was evaluated in patients undergoing PVE. RESULTS: Indocyanine green clearance correlated with the RE Index (r = 0.365, p = 0.007), and ICG-K of FRL (ICG-Krem) strongly correlated with the Rem RE Index (r = 0.738, p < 0.001) in the first analysis. Both the ICG-Krem and the Rem RE Index were significantly correlated after PVE (r = 0.508, p = 0.013) at the second analysis. The rate of improvement of the Rem RE Index from before PVE to after PVE was significantly higher than that of ICG-Krem (p = 0.014). Patients with PHLF had a significantly lower Rem RE Index than patients without PHLF (p = 0.023). CONCLUSION: Relative enhancement imaging can be used to estimate FRL function after PVE.

1) In 2004, Shinshu University School of Medicine started a program for third-year medical students to experience nursing services during both the day and night shifts. The program included lectures on nursing sciences before practice and debriefing sessions after practice.2) Most students viewed this program favorably and felt that the night-shift training was particular meaningful. They also had favorable opinions about the nurses who taught them.3) Some practical issues remain to be solved, such as security during the night shift and the possible excessive burden upon nurses.

A 24-year-old woman with patent ductus arteriosus underwent division of the ductus. On the fifth postoperative day (POD 5), MRSA was detected in pus from the wound. On POD 8, an emergency operation was performed for left tension hemothorax due to a ruptured aorta with MRSA infection. The bleeding site in the descending aorta was covered with a viable omental flap under deep hypothermic circulatory arrest. Although MRSA was detected in the pleural effusion and the aortic wall, the patient recovered from pyothorax, and pneumonia caused by Pseudomonas aeruginosas and acute renal failure. On POD 37, a pseudoaneurysm of the descending aorta was found and graft replacement was performed on POD 56 due to enlargement of the aneurysm. However, MRSA was not detected in the left pleural effusion. The postoperative course was uneventful. Omental transfer should be considered for the treatment of severe aortic wall infection, even in the presense of MRSA infection.

Since 1976, allergic contact dermatitis caused by Chrysanthemum morifolium Ramalk (commercial name: Kinriki) occured on the grower in Tokushima Prefecture. Consequently, a systematic study aimed at the isolation of the allergen of the chrysanthemum was udertaken.
The allergens were contained in the fresh juice of the leaves of chrysanthemum and they were of two types: one was water-soluble and the other was fat-soluble, judging from the results of application test of the skin reaction for sensitized guinea pigs.
The fresh juice of the chrysanthemums was fractionated with ammonioum sulfate saturation method and the active precipitates were chromatographed on Sephacryl S-300 and DEAE-cellulose column, successively. The most active fractions contained sugar and protein, suggesting that the water-soluble principles are high molecular glyco-protein. The other hand fat-soluble fraction was obtained from ethyl acetate extract of the supernatant of 65% ammonium sulfate saturation. The extract was chromatographed on silica gel column and on the thin layer to yield 5, 7-dihydroxychromone (I) and sesquiterpens (II-VI). Unfortunately, at that time the sensitization of ginea pigs was unsuccessfuly. Therefore their compounds could not be tested for the allergenic reaction.
When the precipitates of ammonium sulfate were extrcted with ethyl acetate, the allergenic activeity of the precipitates decreased. However, re-addition of the ethyl acetate extracts to the extracted precipitates recovered the activity. Cross reaction between the juice of leaves and sesquiterpene lactone, alantolactone, failed on skin reaction of sensitized ginea pigs.
