Effects of single moxibustion on platelet aggregation and ATP-release in mice have been studied. Male ddY mice (6 weeks old) were used as experimental animals. 15mg and 5mg of moxa were divided into 6 cones and mice were treated by each 3 cones at right and left LV-14. The electronic aggregometer was used for measuring platelet aggregation and ATP-release using whole blood. Platelet aggregation and ATP-release activities were determined by collagen (final concentration; 2μg/ml) and ADP (final concentration; 20μM) as inducers.
No significant changes on platelet and red blood cell numbers were found after the moxibustion with 15mg of moxa. However, white blood cell numbers were decreased at 1hr and increased at 24hr after the moxibustion.
After the moxibustion with 15mg of moxa, platelet aggregation activity induced by collagen showed no change, but the mild shortness of lag time was observed from 1 to 5hr. While, the mild suppressive effect on platelet aggregation induced by collagen was observed at 1 and 5hr after the moxibustion with 5mg of moxa.
After the moxibustion with 15mg of moxa, mild increase in platelet aggregation activity at 24hr and in ATP-release activity from 1 to 5hr was found. After the moxibustion with 5mg of moxa, an apparent increase in ATP-release activity was observed at 1 and 3hr.
These results suggested that the mild changes in platelet functions were closely related with the response of the coagulation and the fibrinolytic activity in mice.

The Republic of Senegal (hereinafter referred to as “Senegal”) became independent from its former colonial master, the Republic of France in 1960 and formed a democracy. Operations of nursing schools that had been established under the colonial rule were taken over by the Senegal government after the independence. Though having been influenced strongly by French nursing education system, they has developed uniquely and now grown to leading nursing schools of francophone West African countries.
The objective of this manuscript is to focus on nurses that account to the largest number of healthcare workers in Senegal and to trace the historical transition of Senegal's nursing education. The research methods are collection of reference materials, classification of contents, and interviews. As a result, we found that a visiting nursing school established in 1922 is the oldest public nursing school and a total of eight public schools had been established before the independence. The Senegal government laid down National Economic and Society Development Planning and set forth measures for healthcare problems as a priority issue, and has concentrated on nursing education since the independence in 1960. In 1992, the former Ministry of Social Health Activity established the National School of Health and Social Development by integrating 14 public schools related to health welfare. In 2003, it started a practical nurse training program aimed at increasing of the number of nurse graduates and decentralizing nursing education. In 2010, the nursing education standard was revised to improve the quality of nursing education and it will be applied to all nursing schools hereafter.
The need for strengthening management of human resource development and ensuring the quality of that by using the estimates of nurse supply and demand and the like can be suggested as future tasks for the nursing education in Senegal.

Purpose: In Japanese hospitals, it is customary for medical staff to offer condolences to patients who have died before they are discharged. We conducted a preliminary survey to learn the actual status of sending off patients nationwide, we investigated the process from confirmation of death to discharge from the hospital. Methods: An Internet-based questionnaire survey was conducted on medical staff in hospitals nationwide. Results: The number of accesses was 345, and the number of valid responses was 101. Deaths were confirmed by the doctor on duty at night or on holidays in 87% of all hospitals. The carrier came to the patient’s room in 77%. Ceremonies were performed in 13%. The discharge route was the main entrance (8%), back entrance (82%), emergency exit (5%), and dedicated exit (5%). The percentage of positive and negative opinions about holding a ceremony was 23% and 19%. Discussion: A small number (13%) of hospitals offered ceremonies at the time of the send-off.

Objective: As part of the revision on remuneration for medical services in 2012, a new system has been implemented to allow an additional fee for inpatient pharmaceutical services to be added to the basic hospitalization fee.
Methods: We at Kitasato University Kitasato Institute Hospital satisfied all institutional requirements for the new system and were preparing to introduce it from April 2012; however, there was concern about the increased workload due to the additional work of preparing diaries for pharmaceutical services used in calculating the additional fee.
Results: We therefore developed a database titled Diary System for Inpatient Pharmaceutical Services for the preparation and management of diaries. This system allows pharmacists from various divisions to enter data simultaneously and realizes the unified management of records of services performed at various places in the pharmacy.
Conclusions: Since entered data are automatically reflected in the inpatient pharmaceutical service diary and the monthly summary, an advantage compared to paper diaries in terms of efficiency may be expected. Furthermore, the monthly summary of the number of service hours by ward and service type may also be used for service analysis.

In order to promote regional cooperation in palliative care, we developed a regional cooperation clinical pathway for home palliative care that offers simple support and is easy to use. We then administered a questionnaire survey to 14 healthcare professionals with various specialties who were involved in the introduction of the pathway, and we revised the pathway on the basis of the survey results. The revised pathway was then tested in 13 patients who were discharged from 3 designated cancer care hospitals in Toyama City to home care, and another questionnaire survey was conducted afterwards in the same manner. The mean overall score on the questionnaire was 2 in seven, 3 in seven (on a scale of 0 to 3) at the time of introduction, whereas the score after trial use was 1 in one, 2 in four, 3 in five. We believe that more innovative approaches to the implementation of such pathways are required.

Enterovesical fistula is a relatively uncommon complication of colorectal and pelvic malignancies, diverticulitis, inflammatory bowel disease, radiotherapy, and trauma in Asian countries. A case of vesico-ileosigmoidal fistula and a literature review of this disease in Japan are presented. A 70-yr-old male was referred with complaints of urinary pain and pneumaturia. On admission, urinary tract infection and pneumaturia were presented. A barium enema demonstrated multiple diverticulum in his sigmoid colon and the passage of contrast medium into the bladder and ileum. Under the diagnosis of vesico-ileosigmoidal fistula due to suspected diverticulitis of the sigmoid colon, sigmoidectomy and partial resection of the ileum with partial cystectomy were performed. The histopathology revealed diverticulosis of the sigmoid colon with diverticulitis and development of a vesico-ileosigmoidal fistula. No malignant findings were observed. Until the year 2000, a total of 173 cases of vesico-sigmoidal fistula caused by diverticulitis had been reported in Japan. Pneumaturia and fecaluria are the most common types, presenting symptoms in 63% of the cases. Computed tomography, with a sensitivity of 40% to 100%, is the most commonly used diagnostic study. For patients with vesico-sigmoidal fistula, resection of the diseased sigmoid colon and partial cystectomy with primary anastomosis are the safest and most acceptable procedures, leading to the best results.

Objective:
This study aimed to investigate the prognosis of patients with intermediate-risk cervical cancer and to evaluate the necessity of adjuvant therapy.
Methods:
We conducted a retrospective chart review of patients with stage IB–II cervical cancer who underwent type III radical hysterectomy with pelvic lymphadenectomy between 2008 and 2017. In our institution, radical hysterectomy is performed as an open surgery and not as a minimally invasive surgery, and adjuvant therapy is not administered to patients with intermediate-risk cervical cancer. The intermediate-risk group included patients with 2 or more of the following factors: tumor size >4 cm, stromal invasion >1/2, and lymphovascular stromal invasion. Intermediaterisk patients with squamous cell carcinoma were included in the I-SCC group, whereas those with endocervical adenocarcinoma, usual type, or adenosquamous carcinoma were included in the I-Adeno group.
Results:
There were 34 and 18 patients in the I-SCC and I-Adeno groups, respectively. The 5-year recurrence-free survival (RFS) and overall survival rates in the I-SCC group were 90.5% (95% confidence interval [CI], 85.3–95.7%) and 100% (95% CI, 100%), respectively, whereas those in the I-Adeno group were 54.9% (95% CI, 42.0–67.9%) and 76.1% (95% CI, 63.7–88.4%), respectively. Multivariate analysis revealed that endocervical adenocarcinoma, usual type, or adenosquamous carcinoma, and tumor size >4 cm had worse RFS.
Conclusion
The I-SCC group had good prognosis without adjuvant therapy; therefore, adjuvant therapy may be omitted in these patients. In contrast, the I-Adeno group had poor prognosis without adjuvant therapy; therefore, adjuvant therapy should be considered in their treatment.

Placental abruption occurs suddenly and may cause maternal and fetal mortality. Forced delivery is the only way to improve perinatal outcome, but the aftereffects could be severe despite a high survival rate. Our hospital manages approximately 170 cases of maternal transport annually, including cases of severe placental abruption. Longer transport time can lead to undesirable maternal and fetal outcome. Hence this study, we compared the perinatal backgrounds and outcome of placental abruption retrospectively between the cases managed by maternal transport and by the local hospital (our hospital). The study included 54 cases of placental abruption during the period from January 2008 to December 2012, of which 27 cases were managed by our hospital, the other halves were managed by maternal transport. There were 6 intrauterine fetal deaths but not a single maternal death. There were no significant differences in the amount of blood lost and obstetric DIC (disseminated intravascular coagulopathy) score between two groups (p=0.342, p=0.649), and the number of cases that needed anti-DIC therapy and blood transfusion in each group was statistically similar (p=0.807, p=0.115). The time taken from the on-set of placental abruption to delivery was significantly shorter for the cases managed by our hospital (in-hospital management 143±133 minutes, maternal transport management 265±176 minutes, p‹0.05), while obstetric DIC score and Apgar score showed no significant differences (p=0.336, p=0.780) between the two groups. Thus, it could be said there were no correlations between the time taken from onset to delivery and perinatal outcome. It should be noted, however, maternal and fetal outcome of placental abruption could be fatal even with the rapid intervention, so quick diagnosis and management at the first contact are crucial. Thus, we concluded that forced delivery managed by the local hospitals is necessary for the potential better perinatal outcome, and an ideal system to manage maternal and/or neonate transport after the delivery should be established immediately.
