Methadone is a difficult medicine to assess the efficacy at an initial stage because the blood concentration of it varies greatly among individuals and it takes days to reach a steady state and cannot be increased for 7 days. Nevertheless, there are few reports of blood concentration together with effects after administration of methadone about Japanese cancer patients. In this study, we investigated changes in blood concentration and pain score (NRS), and factors that affect blood concentration. Dose per body weight was only correlated with blood concentration of methadone. In the effective cases, NRS decreased chronologically until the 7th day after treatment initiation, and significantly decreased from the 1st day compared to before treatment initiation, but in the ineffective cases, it tended to decrease until the 3rd day, but there was no change thereafter. The blood concentration increased to 110 ng/ml on the 7th day in the effective cases, and in the ineffective cases, it reached the concentration on the 3rd day. Thus there was no correlation between the blood concentration and the drug efficacy. The individual blood concentrations tended to increase slightly or decrease after the 3rd day, but in only one case, it continued to increase. From the above-mentioned, it was shown that the effect could be judged at an early stage, however, since there was a case in which the blood concentration continued to rise until the 7th day, it was considered that the early dose increase within 7 days after initiation should be performed carefully.

A 70-year-old woman who was bedridden because of right hemiplegia attributable to a history of cerebral hemorrhage underwent surgical thrombectomy for pulmonary embolism four years previously. Symptoms of heart failure appeared one year previously, and she was diagnosed with constrictive pericarditis and had been treated with medication by a previous doctor. In the current situation, she visited the previous doctor with the chief complaint of fever, and pericardial effusion was observed on echocardiography. Cardiac tamponade was suspected and she was transferred to our hospital. She was then diagnosed with purulent pericarditis because purulent fluid was observed during pericardiocentesis drainage. Bacteroides fragilis was isolated from the culture of the abscess. The abscess was resistant to conservative antibiotic therapy ; therefore, we performed a pericardiotomy with a left small thoracotomy. The pleural effusion was found to be negative for culture and the patient exhibited a good postoperative course. Purulent pericarditis is refractory with poor prognosis. An appropriate surgical procedure must be chosen considering the patient's activities of daily living. Here, we report a surgical case wherein we chose the left thoracotomy approach and achieved positive results.

The first case was a 67-year-old woman. She had been given a diagnosis of fulminant myocarditis and received a biventricular assist device as a bridge to recovery. A Nipro ventricular assist device (VAD) was implanted into her left heart. She was also found to have moderate aortic insufficiency before the operation, so she received aortic valve replacement (AVR) with a bioprosthetic valve (CEP Magna Ease 21 mm) at the same time. Her cardiac function recovered gradually. Therefore, a weaning operation was scheduled for three months after the VAD implantation. However, her left ventricle motion was very poor when she was taken off of the extracorporeal circulation after removing the VAD, and transesophageal echocardiography (TEE) revealed severe bioprosthetic valve stenosis. When her heart was stopped again and the bioprosthetic valve was observed, the leaflets of the bioprosthetic valve were fused. Commissural fusion of bioprosthetic valve was able to be released using forceps, and the punnus extending under the leaflet was removed. In this way, the function of the bioprosthetic valve was restored. Her cardiac motion became good, and removal from extracorporeal circulation was easily achieved. She left the hospital 100 days after weaning from the VAD. The second case was a 68-year-old woman. She also had fulminant myocarditis. She underwent biventricular assist device implantation and AVR (CEP Magna Ease 19 mm). Her cardiac function recovered, and a weaning operation was scheduled on the 73rd-postoperative day. Preoperative TEE before the weaning of VAD showed severe bioprosthetic valve stenosis. The commissural fusion of the bioprosthetic valve was released and the punnus extending under the leaflet removed at the same time as the VAD was removed. Re-valve replacement was not required. We should therefore consider the possibility of bioprosthetic valve stenosis when VAD implantation and AVR with a bioprosthetic valve are performed at the same time in patients with an extremely reduced cardiac function.

Since students who would like to study Kampo medicine more have no opportunity to communicate each other in Northern Japanese Universities, we newly started joint study conferences held by medical students in 2013. The objectives of this paper are to report on these annually held student-based Kampo study conferences in the Hokkaido and Tohoku areas, and the ways each university studies Kampo medicine. In the conference, the students reported on their club activities. Then they studied the history of Kampo medicine and simulation of abdominal diagnosis, and performed group work on case reports together. The number of student participants in these conferences has tripled over 3 years from 18 to 58 (for a total of 111 participants). All members were satisfied with the content. And this reflects medical students' need for a wider perception of Kampo medicine, rather than a limited one gained in their university club activities. We hope this conference will play a major role in other nationwide student-based Kampo study conferences in the years to come.

Left ventricular thrombus is a complication of left ventricular dysfunction, including acute myocardial infarction, cardiomyopathy, and severe valvular heart disease. Surgical removal should be considered when a thrombus is mobile, when thromboembolism occurs, and when cardiac function has the potential to improve. Two patients with left ventricular thrombus underwent totally thoracoscopic transatrial thrombectomy. A thrombus developed in the apex of the left ventricle after acute myocardial infarction in one patient (Case 1) and during treatment for congestive heart failure in the other (Case 2). The minimally-invasive transatrial approach requires no sternotomy or left ventriculotomy and is thus particularly beneficial for treating left ventricular dysfunction. Moreover, totally endoscopic surgery confers the advantage of a deep and narrow visual field. Therefore, we consider that this strategy is highly effective for treating left ventricular thrombus.

Because adenine is effective for managing cases of radiation-induced and drug-induced leukopenia, it may be effective in cases of antipsychotic-induced leukopenia and neutropenia. Here, we report our experience with patients with leukopenia and neutropenia caused by an antipsychotic overdose or discontinuation of lithium carbonate, in whom adenine administration ameliorated the white blood cell and neutrophil counts. The progress of patients suggests that adenine is effective in cases of leukopenia and neutropenia associated with lithium carbonate discontinuation and an antipsychotic overdose.

In stroke patients, excessive oxidative stress impairs brain nerve cells and leads to arteriosclerosis. On
the other hand, rehabilitative exercise is necessary for the functional improvement and maintenance
after stroke, and exercises themselves increase reactive oxygen species production simultaneously.
Therefore, it is essential to elucidate how exercises influence oxidative stress in stroke patients. We
assessed the effects of exercises on 29 Japanese subacute-phase stroke patients (exercise group, 20;
control group, 9), in terms of oxidative stress by examining changes in reactive oxygen metabolite
(ROM) level (i.e., oxidative stress) and biological antioxidant potential (BAP) level (i.e., antioxidant
capacity) in blood plasma. The exercise group performed two sets of 1-hour exercises 6 days/week for
56 days. The control group performed the same 1-hour exercises, but only on days 1 and 56. ROM and
BAP levels in blood plasma in both groups were measured immediately before and after the exercises
and at rest on days 1 and 56. ROM level significantly decreased and BAP level significantly increased
at rest from days 1 to 56 in the exercise group. However, no significant change was observed in these
levels in the control group.
Conclusion: Regular rehabilitative exercise can improve antioxidant capacity and attenuate oxidative
stress even in stroke patients.

Background: Given the shortage of medical professionals in the Philippines, Barangay Health Workers (BHWs) may play a role in providing postpartum healthcare services. However, as there are no reports regarding BHW activities in postpartum healthcare, we conducted this study to understand postpartum healthcare services and to explore the challenges and motivations of maternal health service providers. Methods: Focus group interview (FGI) of 13 participants was conducted as qualitative research methodology at Muntinlupa City. The results were analyzed according to the interview guide. The proceedings of the FGI were transcribed verbatim, and researchers read and coded the transcripts. The codes were then used to construct categories. Results: Four important activities were highlighted among 11 analysis codes. These activities were “Assessment of postpartum women’s conditions,” “Recommendation to visit a health facility,” “Measurement of blood-pressure and vitamin intake,” and “Providing postpartum health information.” Among five analysis codes, we identified three challenges that BHWs face, which were “No current information regarding postpartum care,” “Some postpartum women do not want to receive healthcare services from BHW,” and “Too many assigned postpartum women.” Among five analysis codes, we identified two reasons for continuing BHW activities, which were “Hospitality to help postpartum women and their family in the community” and “Performance of mission in providing BHW services.” Conclusion: This study is the first to evaluate BHW activities in postpartum healthcare services. Our results indicate that BHWs play a potentially important role in evaluating postpartum women’s physical and mental conditions through home-visiting services. However, several difficulties adversely affected their activities, and these must be addressed to maximize the contributions of BHWs to the postpartum healthcare system.
