Effects of hypothermia on corticoidogenesis (CG) were investigated in primary cultured bovine adrenocortical cells. In order to evoke CG, adrenocorticotropic hormone (ACTH), dibutyryl cyclic AMP (db-cAMP), and high K⁺ were used. In the presence of the above mentioned secretagogues, cells were incubated at 37°C, 27°C, and 20°C for 1 hour. Although there was no difference between the ACTH-induced CGs at 37°C and 27°C, CG was significantly lower at 20°C. Both db-cAMP and high K⁺-induced CGs were significantly lower at 27°C, and were not observed at 20°C.
These results indicate that CG is not affected by moderate hypothermia, and is not eliminated even by deep hypothermia. It is also suggested that ACTH influences not only adenylate cyclase and Ca²⁺ channels, but also various processes of glucocorticoid production and could evoke CG at 20°C in bovine adrenocortical cells.

Emerging ethical issues have prompted Western countries to focus more attention on public health ethics in medical education. To assess the current and future states of public health ethics education in Japan, we analyzed the opinions of public health educators in Japanese medical institutions and explored potential topics for public health ethics curriculums. 1) We mailed self-administered questionnaires to 201 hygiene and public health departments to inquire about their current curriculums and the state of public health ethics education at their institutions. 2) Of the 101 responding institutions, 60.4% were spending 8% of teaching hours on lectures related to ethical issues in public health. 3) Most institutions agreed with a proposal to require the completion of a public health ethics course in medical education programs. 4) Among the major topics chosen to be included in the potential course were ethical issues surrounding public health policy and medical research.

PURPOSE: Ticlopidine hydrochloride, an antiplatelet agent, is believed to have saved life years in many patients with ischemic cerebral vascular diseases in Japan. But severe adverse events have also been reported. The current investigation aimed to compare two hypothetical cohorts treated with and without ticlopidine in terms of risks and benefits of ticlopidine treatment using Markov model.
METHODS: We conducted Markov decision analysis to estimate the number of lives saved and the increase in quality-adjusted life years (QALYs) over the past 20 years by ticlopidine in Japan. Two cohorts of 60-year-old male patients with previous histories of cerebral infarction, one of which treated with ticlopidine and the other not treated with ticlopidine, were compared with respect to the number of deaths and quality of life (QOL) . Data incorporated were the probabilities of the recurrence of cerebral infarction and the associated mortality, adverse events of the drug, and the utility of health status treated with ticlopidine.
RESULTS: Approximately 1, 630, 000 patients were estimated to be on ticlopidine for variable periods of time during the past 20 years in Japan. With treatment, 17, 130 lives were saved, while 1, 338 patients died because of cerebral bleeding, agranulocytosis, severe hepatic dysfunction, or thrombotic thrombocytic purpura, resulting in a net benefit of 15, 792 lives saved by ticlopidine over the past 20 years. In terms of QOL, there was a total increase of 382, 191 QALYs. Sensitivity analyses showed that the older the patients when ticlopidine therapy was started, the smaller the benefits that were gained by treatment.
CONCLUSIONS: Ticlopidine is considered to have made a great contribution in savingmany lives and improving QALYs in the past 20 years in Japan. This kind of analysis based on Markov model can be employed to demonstrate effectiveness of drugs and medical technologies in terms of population health outcomes.

A 74-year-old woman was admitted to our hospital with a diagnosis of a pseudoaneurysm 5 months after graft replacement of the ascending aorta, and underwent re-replacement employing left ventricle venting through a left anterior thoracotomy. Culture of the thrombi in the pseudoaneurysm revealed Psuedomonas infection. On the 11th postoerative day, a single-stage procedure of irrigation, debridment, and immediate closure with omental transposition was performed. Although the chest CT scan 1 month after the omental transposition revealed a residual abcess, it was completely obliterated after 2 months without further operation.

Objectives

  The aim of this study was to investigate the knowledge, attitude, and practice (KAP) of healthcare providers regarding the utilization of oxytocin for induction or augmentation of labor.

Methods

  A qualitative study composed of direct observation and individual interview was conducted at a national tertiary maternity hospital in Phnom Penh, Cambodia in January and February 2013. The progress of labor in women who received oxytocin for induction or augmentation of labor was directly observed to confirm the healthcare providers’ management of oxytocin infusion. The attending doctors and midwives were individually interviewed after the women delivered.

Results

  During the study period, 10 women were observed, and 12 healthcare providers (three doctors and nine midwives) were interviewed individually. Indications for labor induction or augmentation seemed to be appropriate for nine women. However, we found discrepancies between the national protocol and healthcare providers’ knowledge and actual practices. For example, 11 healthcare providers had never read the national protocol for the management of labor induction and augmentation, which implied limited access to the correct knowledge. A misconception was noted in that the sudden increase of oxytocin was not dangerous during the second stage of labor, despite the establishment of a good contraction pattern. Furthermore, a lack of unified initial dose and extremely high maximum dose above that recommended by the national protocol were observed. About half of observed women were not monitored for more than 2 hours from the beginning of oxytocin infusion.

Conclusion

  　In the present study, lack of knowledge, misconceptions regarding the management of oxytocin infusion, and a large gap between the national protocol and the actual clinical practices were confirmed. To maximize patient safety and therapeutic benefit, dissemination of the national protocol through in-service training is required.

The decrease in physical activity in elementary school children is an important problem in Japan. Previous studies have shown that physical activity during the summer vacation is lower than during the school days, and a program for increase in physical activity during the summer vacation are required. Therefore, the purpose of this study is to assess the effectiveness of physical education homework and exercise events during summer vacation in elementary school children. A total of 67 children in grade 4 were assigned to the two groups for each school: the control school (n = 39) or the intervention school (i.e., did physical education homework and participated in exercise events; n = 28). Physical education homework was constituted of four exercise programs per day. Additionally, exercise events were carried out four times during the summer vacation. Physical activity before and during the summer vacation were measured by accelerometer (Lifecorder EX). The decline in physical activity of the intervention school was less than the control school, and significant interactions were indicated by two-way repeated ANOVA (Step count: F (1, 65) = 6.704; Light-intensity physical activity, LPA: F (1, 65) = 4.365; Moderate- to vigorous-intensity physical activity, MVPA: F (1, 65) = 6.088, all P < 0.05, respectively). After adjusted for sex, percentage of overweight, participation of sport activity, and each physical activity, significant trends of interactions about the step count, LPA, and MVPA were shown (Step count: F (1, 61) = 3.982, P = 0.050; LPA: F (1, 61) = 3.243, P = 0.077; MVPA: F (1, 61) = 2.916, P = 0.093). These results suggest that combined use of physical education homework and exercise events are effective to attenuate the decrease in physical activity during summer vacation in elementary school children.

We performed combination therapy with modified oxaliplatin/l-LV/5-FU (mFOLFOX) in a patient with recurrent colorectal cancer who had peritonitis carcinomatosis. In this patient, mFOLFOX therapy resulted in disappearance of ascites and a decrease in carbohydrate antigen 19-9 (CA19-9), and improved quality of life (QOL) of the patient. This 62-year-old man was diagnosed with ascending colon cancer and metastatic cancer of the liver. Right hemicolectomy and right hepatic lobectomy were performed. We had started to treat with TS-1 in ambulatory care, however, he had peritonitis carcinomatosis with massive ascite reservoir on CT and peritoneal dissemination after a half year postoperatively. Furthermore, his ECOG Performance Status (PS) was rated as level 3. Therefore, we performed puncture of ascites and palliative mFOLFOX6 therapy. After ten courses, ascites and abdominal induration had disappeared and PS recovered to level 1. At present, CPT-11/l-LV/5-FU (FOLFIRI) are being administered for peripheral neuropathy and metastatic tumor associated with mFOLFOX6. The patient is spending his daily life satisfactory after FOLFIRI without abdominal swelling or ascites, and thus mFOLFOX6 may be an option for palliative therapy against massive ascites in patients with advanced colorectal cancer. The usefulness of palliative mFOLFOX6 therapy for patients with massive ascites should be evaluated in a well-designed clinical trial.Palliat Care Res 2008; 3(2): 316-320

This paper proposes a method for evaluating and scoring the activities of rehabilitation service users in order to pinpoint the problems with the health service of this kind and set the adequate targets for each user. Sincs the Nursing Care Insurance System was introduced in Japan in 2000, it has been argued that home-visit rehabilitation services should be excluded from home-nursing care services. However, the methods of certifing that nursing care is required are not fully established yet for setting the rehabilitation targets for service users. As things stand, it is recommended that such a method as the Functional Independence Measure (FIM) or the Barthel Index (BI) should be utilized. However, these methods only evaluate “performing activities” (the activities that a user usually performs). In order to set the users' targets, we thought it necessary to establish a method for evaluating “possible activities” (the activities that a user is able to perform at his/her full capacity). We have established a method called Functional Scoring (FS) which evaluates and scores the both performing and possible activities based on the same evaluation items. We conducted experimental evaluations on the home-visit rehabilitation users for one year from October 2005 to September 2006. When the first evaluations in 2005 were compared with the second evaluations in 2006, the total score of the performing activities significantly increased from 44.1±13.7 to 47.8±14.2 (P<0.05). Although the total score of the possible activities did not significantly increase, it demonstrated an upward trend from 49.6±13.2 to 51.6±13.5. The result suggests that our method is useful for distinguishing between the performing and possible activities. The proposed method enables us to adequately recognize the problems each user has, and to set the rehabilitation target for each user, which can be shared between the user, care personnel, and care service provider.
