Following the Great East Japan Earthquake, many pharmacy students conducted support activities which was no requirement of pharmacist’s license. Although some pharmacy students reported their activities, there are no studies comprehensively analyzing this phenomenon. The purpose of this study was to survey the support activities of pharmacy students and to analyze the corresponding conditions. We conducted personal interviews with 22 pharmacy students involved in the support activities. The questionnaire included items about a student’s general attributes, activities, activity duration, and relevant locations. Further, we analyzed data on their attributes and personal information with respect to the support activities. Data on the activities were classified into 10 categories and evaluated based on pharmaceutical knowledge levels required for the support activities. According to the results of the interviews, the phases of the activities were classified into “sub-acute phase” and “chronic phase.”The relevant locations were medication collection points, shelters, and transit points for medical teams, temporary clinics, and temporary housing. Furthermore, according to the classification of activities by knowledge levels, activities depended on the students’ pharmaceutical knowledge; if they appropriately selected the activities (based on their pharmaceutical knowledge level), they could effectively participate in the support activities. The results of our survey suggest that pharmacy students can assist healthcare professionals, although the relevant activities are limited by the duration and pharmaceutical knowledge.

A 65-year-old-man was admitted with congestive heart failure and septic shock associated with suspected mitral valve infective endocarditis. An echocardiogram revealed vegetation attached to the chordae, high density lesions in both papillary muscles, and severe mitral regurgitation. An emergency operation was performed. Vegetation was been attached to the chordae. Multiple myocardial abscesses were noted in both papillary muscles and surrounding myocardium. However, there were few noticeable lesions on mitral valve leaflets and annulus. The anterior mitral leaflet was resected together with the chordae and the papillary muscles containing the myocardial abscesses. Mitral valve replacement was performed using a 27mm SJM valve after the other myocardial abscesses were drained. Klebsiella pneumoniae was cultured from the vegetation and the myocardial abscesses. Cases of myocardial abscess associated with infective endocarditis at the site of the papillary muscles and in the areas of the myocardium are very rare. It was assumed that the myocardial abscesses were probably due to the septic state from infective endocarditis, since myocardial abscesses was recognized in multiple sites and at a distance from the valve leaflets and annulus.

An 81-year-old woman developed abdominal pain after off-pump CABG (OPCAB) for unstable angina pectoris. X-ray film and CT scan showed paralytic ileus the day after surgery. A presumptive diagnosis of mesenteric ischemia was made and exploratory laparotomy was performed. During surgery, however, there was no sign of mesenteric ischemia. The patient still complained of abdominal pain after the laparotomy, so selective angiography of the mesenteric artery was performed. The angiography showed remarkable vasospasm of the superior mesenteric artery (SMA) and diagnosis of nonocclusive mesenteric ischemia (NOMI) was made and continuous intra-arterial perfusion of papaverine into the SMA was started. Control angiography during papaverine perfusion showed a clear reduction of vasospasm. Thereafter, the patient developed diffuse peritonitis due to intestinal gangrene on postoperative day 12 and was compelled to undergo extensive resection of the intestine and sigmoidectomy. She could not be weaned from the ventilator due to respiratory insufficiency and died of multiple organ failure about 5 months after OPCAB. NOMI can develop even in OPCAB, in which cardiopulmonary bypass is not required. Therefore maintenance of stable hemodynamics intraoperatively, careful management of the postoperative state and early diagnosis and therapy are essential to prevent NOMI.

A 70-year-old-woman was admmitted to receive an operation for aortic arch aneurysm. Total arch replacement was carried out under deep hypothermic circuratory arrest with selective cerebral perfusion. During sternal closure, her blood pressure dropped to 60/30mmHg suddenly, and massive venous bleeding started from the substernal space which turned out to be hemorrhage from the laceration of the pulmonary trunk. Controlling the bleeding by finger compression, rapid introduction of cardiopulmonary bypass was carried out and the laceration was closed by a pericardial patch. The postoperative course was uneventful. In this case, compression of the pulmonary trunk by the aortic arch aneurysm may have caused the fistula formation between them, and decompression of the aneurysm probably induced the rupture of the pulmonary trunk. If the preoperative computed tomogram had showed the compression of the pulmonary artery by the aneurysm, a careful exploration of the main pulmonary artery and a removal of the thrombus should have been performed, even when the preoperative diagnostic evaluation failed to reveal aortopulmonary fistula.

A 45-year-old man underwent total arch replacement for acute type A aortic dissection. Vital signs during the operation remained stable, but sinus tachycardia was recognized about 7h postoperatively, followed by a high level of PaCO₂, low level of PaO₂ and metabolic acidosis. Then, blood pressure decreased, accompanied rapid elevation of body temperature to 39.7°C. Body temperature was decreased gradually by cooling the whole body, however, coma, anuria and hypoxemia persisted. A diagnosis of malignant hyperthermia was made and Dantrolene was administered. However, the patient died of multiple organ failure 7 days postoperatively. The serum level of CPK increased to 12, 446IU/l and serum myoglobin elevated to a very high level (36, 500ng/ml) 2 days postoperatively. Although, it is very rare for malignant hyperthermia to develop after open-heart surgery, physicians must keep this disease in mind if sudden hyperthermia of unknown origin is demonstrated.

A 74-year-old man was admitted to our hospital to undergo an operation for distal aortic arch aneurysm with chronic aortic dissection. The first operation was attempted through left lateral thoracotomy. Since the aorta had a severely calcified false lumen, conventional aortic replacement was considered to entail greater risk and graft replacement was given up. As an another option, endovascular stent grafting via the aortic arch through median sternotomy was selected as a second operation. Deep hypothermic circulatory arrest with selective cerebral perfusion was used during delivery and deployment of the stented graft through the aortotomy site. The distal stented graft was deployed into the true lumen at the ninth thoracic vertebral level. Neither endoleaks nor complications were observed. Postoperative computed tomography showed complete thrombosis of the distal aortic arch aneurysm and the false lumen. The postoperative course was uneventful. Transaortic endovascular stent grafting is an effective and less invasive treatment for aortic arch aneurysms with severely calcified aorta.

We have previously reported on a predictive model for deficiency-excess pattern diagnosis that was unable to predict the medium pattern. In this study, we aimed to develop predictive models for deficiency, medium,and excess pattern diagnosis, and to confirm whether cutoff values for diagnosis differed between the clinics. We collected data from patients' first visit to one of six Kampo clinics in Japan from January 2012 to February 2015. Exclusion criteria included unwillingness to participate in the study, missing data, duplicate data, under 20 years old, 20 or less subjective symptoms, and irrelevant patterns. In total, 1,068 participants were included. Participants were surveyed using a 153-item questionnaire. We constructed a predictive model for deficiency, medium, and excess pattern diagnosis using a random forest algorithm from training data, and extracted the most important items. We calculated predictive values for each participant by applying their data to the predictive model, and created receiver operating characteristic (ROC) curves with excess-medium and medium-deficiency patterns. Furthermore, we calculated the cutoff value for these patterns in each clinic using ROC curves, and compared them. Body mass index and blood pressure were the most important items. In all clinics, the cutoff values for diagnosis of excess-medium and medium-deficiency patterns was > 0.5 and < 0.5, respectively. We created a predictive model for deficiency, medium, and excess pattern diagnosis from the data of six Kampo clinics in Japan. The cutoff values for these patterns fell within a narrow range in the six clinics.
