A 64-year-old man with a history of abdominal aortic occlusion was admitted because of anterior chest pain. Angina pectoris with ischemic mitral regurgitation were diagnosed by transthoracic echocardiography and coronary artery angiography. He underwent coronary artery bypass grafting and mitral valve annuloplasty with a 26-mm Physio-ring. Because of difficulty in weaning from cardiopulmonary bypass, he required IABP support which was introduced via the ascending aorta. On the 2nd postoperative day, IABP was discontinued and the sternum was closed. His postoperative course thereafter was uneventful without any neurological complications. Postoperative echocardiogram showed good mitral valve function. He was discharged 16 days after surgery.

A 6-year-old boy was admitted with infective endocarditis and aortic regurgitation. Clinical signs of infection were severe. The leukocyte count was 13, 100/μl and the C-reactive protein (CRP) was elevated to 17.2mg/dl. Blood culture was positive for Staphylococcus aureus. Echocardiography showed a vegetation 3mm in diameter on the aortic valve, and a perforation of the right coronary cusp with moderate aortic regurgitation. With antibiotic therapy, clinical signs and laboratory data of infection improved at an early stage. We decided to operate after his complete recovery from infection. Laboratory data normalized completely in 6 weeks, but echocardiography demonstrated aneurysmal change of the right coronary sinus and severe aortic regurgitation. The Ross operation was performed on the 44th day. At operation, it was noted that the non-coronary cusp was destroyed completely leaving only strings of fibrous tissue. A perforation of 3mm in diameter was also found on the right coronary cusp. There was a mural aneurysm near the right coronary orifice without abscess formation in the surrounding structure. A pulmonary autograft was transplanted to the aortic root after resection of the destroyed aortic cusps, aortic root and the mural aneurysm. The right ventricular outflow tract was reconstructed using an autologous pericardium as a posterior wall and the Monocusp ventricular outflow patch (MVOP) #22 as an anterior transannular patch. The postoperative course was uneventful. Postoperative echocardiography revealed no aortic regurgitation.

The very first session of the symposium on ‘cancer and acupuncture’ was held at the 53rd Annual Conference of the Japan Society of Acupuncture and Moxibustion (JSAM). It suggested the efficacy and potential of acupuncture and moxibustion not only for cancer but also for cancer patients. This is the second session for further discussion. In recent years, acupuncture and moxibustion treatment for cancer patients has come to the world's attention, and many reports about its expediency and beneficial effect have been conducted in Japan and in the world. However, the adaptation range of acupuncture and moxibustion treatment for cancer is still limited because there is not enough evidence, so compilations of more sufficient case reports or research for presentation and effects in preventing relapse of cancer are required to prove its reliability. Acupuncture and moxibustion are used as one of the medical treatments directed at relieving symptoms and life-sustaining treatment in hospitals today. Earlier, frequent acupuncture treatment led to significant efficacy for cancer patients, and it is also reported that the number of lymphocytes increases in sequential acupuncture treatment but the number tends to return in a short time after cessation of treatment. Sequential autonomic immune therapy over a long term revealed several significant effects as follows; lymphocyte activation while the lymphocyte count remained, increase of cytokine (IL 12, IFNγ, TNFα, etc.) production and Th 1, Th 1/Th 2, immunostimulatory activity effect, reduction of tumor markers down to or close to normal, reduction or resolve of malignant neoplasm and recurrence prevention for unoperated cancer patients, QOL improvement with symptoms relief and life prolongation. In this seminar, it suggested that acupuncture and moxibustion are potential and appropriate treatments for cancer and further research in this field is required.

This is the third symposium on 'cancer and acupuncture and moxibustion'. Many physicians and intellectuals are skeptical of the use of Western medicine for cancer patients, which often lead to serious adverse events. Acupuncture and moxibustion, which is capable of improving quality of life (QOL) and activating immunity with minimal side effects is also expected to have beneficial effects on various stages of cancer patients, such as prevention of development or recurrence of cancer and palliative care. In fact, evidence has recently accumulated in the field. Dr. Fukuda, Associate Professor of Meiji University of Integrative Medicine, who reported the usefulness of acupuncture and moxibustion in palliative care in the first symposium and bibliographical information in the second has reported this time on the topic of safety and effectiveness of acupuncture on chemotherapy-induced peripheral neuropathy. Dr. Kurokawa from the National Defense Medical College reported the effectiveness of acupuncture on physical and psychological symptoms, QOL, prevention of adverse events, and pre-and post-operative disorders in cancer patients. Dr. Kouchi from Saitama Medical School reported on the usefulness of acupuncture in the university hospital and factors which influence the effect. Dr. Nakamura from Morinomiya University presented a case with chemotherapy-related symptoms who had been cared for with a long-term application of moxibustion. In contrast to these reports on the efficacy of the acupuncture for chemotherapy-and radiotherapy-induced side effects, Dr. Magara from Somon Hachipuji Clinic, who had consistently reported a preventive effect of autonomic immune therapy that involves acupuncture without Western clinical treatment from the first symposium, this time presented topics regarding improvement in the immunity by increasing various cytokines, the possibility of reduction of a tumor even in a case of advanced cancer that cannot be treated with a surgical approach, reduction of the recurrence rate among cases who were treated with his approach as compared with those under conventional approaches. He insisted we should concentrate our efforts on research on preventing the recurrence of cancer with approaches that activates the natural healing process of human beings.
We concluded that clinical trials with a larger sample are needed to clearly identify the usefulness of acupuncture and moxibustion for cancer patients.

A 28-year-old man was involved in a traffic accident that sandwiched his chest between a wall and a truck. Shortness of breath and other symptoms started to appear several years later. Echocardiography at that time showed severe tricuspid regurgitation due to a failed valve and ruptured chordae in the anterior leaflet. He was followed up with medication. Leg edema developed at the age of 62 years and worsening symptoms of heart failure over a period of 6 months indicated a need for surgery. Intraoperative findings revealed the ruptured chordae attached to the anterior leaflet and a scarred myocardium at the septomarginal trabeculation. The tricuspid valve was surgically repaired, the anterior leaflet chordae were surgically reconstructed, an annuloplasty ring was implanted to address the tricuspid regurgitation and atrial fibrillation was treated using the Maze procedure. Surgery 34 years after trauma has improved hemodynamic cardiac function and normalized the cardiac rhythm in this patient.

Objective: The Hyogo Hospital Pharmaceutical Society has been conducting an original pharmacy postgraduate education program, “lifelong learning program (to nurture pharmacy specialists)”, since 2002 using the Internet. To understand the status of using this program, this study employed a questionnaire survey involving all registered members.
Methods: Subjects were all members (1,870) of the society. Questionnaires were distributed and collected by mail.
Results: Only 20.1% of the members had experience of using the program, and the frequency of using it was less than once per 6-12 months in 60% of the members. Their level of awareness concerning the acquisition of credits for lifelong learning was 36.9%. The program category they wished to take was an infection-related program in 26.1% of the members, which was the highest.
Conclusion: As reasons for only a small number of members using the program, the following are considered: loss of user’s ID and password required to login, and lack of awareness concerning the acquisition of credits for lifelong learning offered by the Japanese Society of Hospital Pharmacists. As future issues, we must encourage members to obtain a new password and be proactively involved in preparing new program categories that the members wish to take, in order to promote the continuous use of the program.

We have previously reported that hot-spring hydrotherapy for a short duration can change hormone levels in the blood and quantitatively as well as qualitatively regulate leukocytes and their subpopulations. In this study, we examined the effect of hot-spring hydrotherapy on the lymphocytes expressing β2-adrenergic receptors (β2-ARs). We obtained peripheral blood from 9 healthy volunteers (age, 49.7±11.2 years) at the same sampling time before and after (the next day) hot-spring hydrotherapy, and measured the total and differential leukocyte counts and the levels of 3 catecholamines (adrenaline, noradrenaline, and dopamine). We also analyzed the β2-AR of lymphocyte subsets by combination with fluorescent monoclonal antibodies (CD3, CD4, CD 8, CD 19, and CD56) by using flow cytometry.
The number of granulocytes significantly decreased after hot-spring hydrotherapy (p < 0.05). The ratio of β2-AR+ CD4+ cells and β2-AR+ CD3+ cells was low, but that of β2-AR+ CD56+ cells and β2-AR+ CD8+ cells was high. The CD8+ cell and CD56+ cell counts tended to increase after hot-spring hydrotherapy, but no significant variation was found in the β2-AR+ cells of each subset. Adrenaline levels also significantly decreased after hot-spring hydrotherapy (p < 0.05). The rate of change in adrenaline levels before and after hot-spring hydrotherapy was highly correlated with the rate of change in the levels of CD56+, CD8+, and β2-AR+ CD56+ cells. Thus, we found a difference in thepercentage of β2-AR-expressing cells in the lymphocyte subsets. Therefore, it is possible that a short duration of hot-spring hydrotherapy decreased adrenaline levels and quantitatively influenced the natural killer cells and CD8+ cells, which express large amounts of β2-AR.

From 1985 through 1994, 12 consecutive patients with Taussig-Bing anomaly underwent an arterial switch. Age at operation varied from 8 to 42 months (mean 21 months). Coarctation of the aorta was present in 6 patients (including 4 with hypoplasia of the aortic arch), interruption of the aortic arch in one, straddling mitral valve in one and subaortic stenosis in two. The relationship of the great arteries was D-transposition in 11 patients (oblique in 6 and anteroposterior in 5) and side-by-side in one. Eleven patients had previous palliative surgery. Pulmonary artery banding was done in 11 patients, Blalock-Hanlon in 3, carotid flap aortoplasty in 3, subclavian flap aortoplasty in 2, extended aortic arch anastomosis in 2 and ligation of PDA in 1. The Lecompte maneuver was adopted in all but one patient with side-by-side great vessels. Intraventricular reconstruction was done through the right ventricle in 11 patients and through the right atrium in one who underwent one-stage repair. There was one early death, which was related to thrombosis of the superior mesenteric artery. One patient with side-by-side great vessels died at home 6 months after the arterial switch operation. The suspected cause of death was myocardial infarction due to compression of the left coronary artery by the pulmonary artery. In the follow-up of 10 patients ranging from 1.8 to 9.4 years (average 6.3 years), one required reoperation for pulmonary stenosis. We conclude that two-staged arterial switch operation of Taussig-Bing anomaly with D-transposition can be performed with low mortality, but there seems to be some risk of the compression of the left coronary artery in the original Jatene method for Taussig-Bing anomaly with side-by-side great vessels.

A 5-year-old boy with tricuspid atresia who underwent the Björk procedure died due to right atrial thrombus and left pulmonary embolus 37 days after operation. It is suggested that thromboembolism may be a frequent complication after the Björk procedure due to the turbulent blood flow at the right atrio-ventricular anastomosis and also due to congestive blood flow. Anticoagulation therapy seems to be essential for postoperative management.

Locally advanced breast cancer (tumor > 5 cm, widespread infiltration of the skin and muscle, or metastases to lymph nodes) is difficult to resect by surgery, and even when it is resectable, there is a high probability of local recurrence and distant metastasis. Therefore, systemic therapy should be administered first. However, as cutaneous infiltration progresses, the patient's quality of life is impaired by pain, bleeding, presence of exudates, and a foulsmelling odor. Treatment with Mohs paste with systemic therapy can control symptoms associated with skin infiltration and can also be expected to decrease tumor volume.Herein, we report a case in which a tumor was resected following Mohs paste and systemic chemotherapy administration, and the skin defect was reconstructed with a latissimus dorsi myocutaneous flap. We also review the literature for previously reported cases of breast cancer involving Mohs paste.
