We successfully performed one-stage definitive repair for 3 infants weighing 4.2, 6.1 and 5.2kg with complex coarctation without homologous blood transfusion. The priming volume of the bypass circuits was 195ml, and their lower hematocrit values during cardiopulmonary bypass were 15, 16 and 13%, respectively. In order to diminish the aortic cross clamp time, the aortic arch was repaired with the heart beating, using isolated cerebral and myocardial perfusion methods. The base excess in each patient decreased to -9.4, -8.0 and -4.9mEq/l during the rewarming phase, however, their postoperative hemodynamic and respiratory conditions were satisfactory. They have grown without any sequelae for at least 2 months.

In the present study, the effects of bulb type palatal lift prosthesis (bulb-PLP) therapy on nasality and velopharyngeal function (VPF) of patients with velopharyngeal incompetence (VPI) following palatoplasty were longitudinally assessed.The subjects included 18 patients (3 to 52 years of age) who had shown persistent VPI following palatoplasty and who had received bulb-PLP therapy. Nasality and VPF were assessed by perceptual voice analysis, nasometer test, blowing test, and cephalometric radiographic examination. Based on the outcomes of bulb-PLP therapy, the subjects were classified into two groups: the effective group and the ineffective group. Furthermore, the obturating and VPF-activating effects by bulb-PLP therapy were analyzed, and factors relating to different VPF activities were determined.All subjects achieved adequate VPF by wearing a bulb-PLP. After treatment, 10 patients (55.6%) achieved successful activation of VPF without bulb-PLP (the effective group), while persistent VPI remained in 8 patients (the ineffective group). The beginning-blowing ratio of the effective group was significantly greater than that of the ineffective group (P < 0.05) and the velopharyngeal distance (V-P distance) of the effective group tended to be smaller (P = 0.07). Regarding the shape of the bulb head, the angular type was dominant in the ineffective group, while the round type was dominant in the effective group.Bulb-PLP therapy was useful for providing adequate VPF activation. Possible signs of the subsequent effective activation of VPF are considered to be: 1) preexisting adequate VPF on blowing, 2) smaller V-P distance, and 3) synchronized palatopharyngeal movement.

Teaching ambulatory-care medicine is essential for primary-care education. However, few studies of ambulatory-care training have been done in the past decade. We performed a nationwide survey to examine whether and how ambulatory medicine is taught to medical students and residents. We sent questionnaires to all medical schools (n=80) and accredited teaching hospitals (n=389) in February 2001. The response rates were 83.3% and 79.2%, respectively. Fifty-one (78.5%) of the 65 medical schools provided ambulatory-care education, although the programs varied considerably from school to school. Only 104 teaching hospitals (26.7%) had an ambulatory-care training program.

Background: Globalization urges us to discuss rationale and policy towards establishing a medical education accrediting body in Japan. Experience of General Medical Council （GMC） suggests us some useful lessons.
Method: Based on our visits and investigation into in GMC, we inquire how Quality Assurance （QA） was introduced in UK with what incentives and how QA has brought reforms in the medical schools in UK.
Result: Since 2003, GMC has changed its policy for QA from ‘inspection’ to ‘dialogue’. Dialogical QA asks a medical school to think critically of their education and consider vigorous actions for further improvements.
Discussion: Implications from the experience of GMC are: 1.QA process in GMC makes medical schools take robust steps towards changes, 2. Sharing the rational and policy for QA created the solid base for its effective implementation, 3. There are possible difficulties in establishing structure to do an enormous amount of coordinating work, which is necessary for constructing ‘dialogue with medical schools’.

Objective: From September 2009, the Department of Pharmacy of Kitasato University Kitasato Institute Hospital started operation room services, and the pharmacist in charge also responds to the inquiries from the operation room staff (doctors and nurses) concerning pharmaceutical compounds.  In the present study, we collected the inquiries and analyzed their contents in order to understand the information of pharmaceutical compounds required by the operation room staff.
Methods: The inquiries from operation room staff received between October 2009 and March 2012 were collected and the contents were analyzed.
Results: A total of 625 inquiries (mean, 20.8 inquiries per month) were received.  Regarding the contents of inquiry, the most frequent inquiry was on “the presence or absence of the stock” (70.7%), followed by “drug information” (17.0%), “handling of controlled substances” (5.9%), and “handling of non-controlled substances” (4.2%).  For “the presence or absence of the stock,” the most common pharmaceutical compounds inquired were antibacterial agents, anesthetics, and infusion fluids.  For “drug information,” the contents were diverse, ranging from drug efficacy to operation method, whether compounds are included in hospital drug list, in-hospital preparations, and drug selection.  For “handling of non-controlled substances,” the most frequent inquiries were associated with the expiration date after unsealing.
Conclusion: The most frequent inquiry from the operation room staff was on “the presence or absence of the stock,” and the common subject of inquiry was presumably pharmaceutical compounds frequently used at the time of surgery.  The analysis showed that the operation room requires a wide range of information.

Although postgraduate training in an ambulatory care setting is recognized as beneficial in Japan, such training has not been widely implemented. In April 2001 we surveyed all 389 accredited teaching hospitals in Japan about their ambulatory care training. We asked 1) whether they provide a postgraduate training program in ambulatory care, particularly for problems commonly encountered in primary care settings, 2) if such a program was provided, how it was organized, and 3) if such a program was not provided, what the reasons were. One hundred eighty physicians responsible for the residency programs of 120 hospitals replied (response rate, 87%). Most residents at these hospitals see patients in outpatient clinics regularly during their training. Many faculty members supervise their residents at the outpatient clinic and also see their own patients. Sixty-eight percent of the respondents did not set teaching objectives for ambulatory care training. Frequently mentioned barriers to providing ambulatory care training were limited space and tight outpatient schedules. To promote postgraduate ambulatory care training in accredited teaching hospitals, adequate resource allocation and a national policy are needed.

  In the health resorts of Germany, the empirical effects of the unique natural capital and environment on humans are verified by scientific methods such as medicine, meteorology, and chemistry, and then approved as therapeutic drugs. Natural capital is provided in various forms for the maintenance of health, treatment of diseases, and recovery from fatigue and stress. Natural capital include hot springs, natural gases, and peloid (from the soil), as well as climate and oceans. The categorization of health resorts is defined by the type and quality of natural capital available. Due to their unique characteristics, a system that allows users to select the health resorts that suit their specific needs has been established, enabling them to utilize natural capital effectively for health promotion.  Considering the current state of Japan, country with an abundance of natural capital that is considered underutilized, we visited Bad Homburg and six health resorts located in Germany’s Black Forest located in the southwestern part of the country to learn about the current state of their health resorts.  All the health resorts we visited were excellent centers certified by the German Spas Association and German Tourism Association. Bad Wildbad and Keidel Mineral-Thermalbad, both thermal health resorts, maintain the provision structure for medical treatment and tourism. Against a background of growing interest in the environment, they utilize the land and natural capital to their advantage by incorporating the elements of trendiness, fun, and excitement to revitalize the local and the health resorts’ communities.  Due to the differences in the structure, environment, and systems between the hot springs in Japan and those in Germany, it would not be easy to apply the current state of the German health resorts to similar resorts in Japan. However, Japan is rich in natural environments such as forests and hot springs and is blessed with a quantity and diversity comparable to that of Germany’s Black Forest. Therefore, we believe that there is potential for further utilization of Japan’s natural capital for health promotion. The efforts of the German health resorts could direct and inspire us.

Today, well over 160, 000 patients undergo dialysis throughout Japan. The number of patients who are newly required to receive it is increasing year by year. Given that situation, our hospital has annually held a seminar since October 1994 for patients with renal diseases. The purpose is to slow the deterioration of renal function and to delay the introduction of dialysis by encouraging the patients to acquire a habit of taking high calory, low protein food.
This seminar must have help the patients get more knowledgeable about morbidity and learn the benefit of low protein rice-based diet. Now that three years have passed since the opening of the course, we reviewed the outcome, comparing the effects of old and new restrict diets.
A difference began to appear 9-2 months after the lst seminar between the seminar participants and the non-participants (control group) who received guidance only at the outpatient ward. The average rate of decrease in the serum creatine level of those participants who eated lowprotein rice was 0.029 and that of those participants who did not eat the restricted food was 0.166 (p<0.05), compared with 0.262 in the control group. We concluded that the difference is ascribable to the effect of the seminar. We would like to contribute to the well-being of the patients by enriching the content of the seminar and continuing to hold it.

Vascular ring is a congenital anomaly of the aorta and its branches that compresses the trachea and/or esophagus. Infants with vascular ring may have critical dyspnea due to airway obstruction, which is called a dying spell. In addition, vascular ring leads to secondary malacia of the trachea and bronchus. To prevent dying spells and progression of malacia, vascular ring should be diagnosed as soon as possible. We report here a case of a 5-month-old girl with vascular ring affecting the right aortic arch, aortic diverticulum, and ligamentum arteriosum. She had stridor from birth and afebrile convulsions due to dying spells at 5 months of age. Transthoracic echocardiography revealed right aortic arch, and plain computed tomography (CT) revealed severe tracheal stenosis. Finally, we diagnosed vascular ring based on contrast-enhanced CT imaging. We should consider vascular ring when we encounter infants with stridor. Echocardiography is helpful for examining the structure of aorta, and if an aortic anomaly is noted, contrast-enhanced CT should be performed to diagnose vascular ring immediately.

BACKGROUNDSeveral studies have suggested that the exposure to cadmium (Cd) increased mortalities from renal diseases, cardiovascular diseases and malignant neoplasm, including lung cancer and prostate cancer among inhabitants living in Cd-polluted areas and factory workers. This study aimed to assess the influence of environmental exposure to Cd on long term outcome of inhabitants living in an area polluted by Cd.

METHODSA 22-year follow-up study was conducted with 3119 inhabitants (1403 men and 1716 women) living in the Cd polluted Kakehashi River basin in Japan. The subjects were divided into 4 groups according to the amount of urinary Cd level (< 3.0 µg/g creatinine (Cr), 3.0 - 4.9 µg/g Cr, 5.0 - 9.9 µg/g Cr, and ≥ 10.0 µg/g Cr). Mortality was calculated by the person-years method. Hazards ratios (HR) and 95% confidence intervals (CI) were assessed by the Cox's proportional hazard model.

RESULTSCompared with urinary Cd < 3.0 µg/g Cr group, the HR of 5.0 - 9.9 µg/g Cr and ≥ 10.0 µg/g Cr groups were significantly increased after adjustment for age in both sexes: 1.24 (95%CI 1.01 - 1.51) and 1.48 (95%CI 1.17 - 1.90) for men; 1.64 (95%CI 1.17 - 2.28) and 1.78 (95%CI 1.27 - 2.50) for women. The most frequent cause of death was malignant neoplasm in men and cardiovascular diseases in women. The significant increase in mortality risk for cardiovascular diseases was observed in the subjects with ≥ 10 µg/g Cr in both sexes: 1.79 for men (95%CI 1.02 - 3.12) and 2.38 for women (95%CI 1.11 - 5.07). When the subjects were divided into 2 categories (< 20 µg/g Cr and ≥ 20 µg/g Cr), the HR of the urinary Cd ≥ 20 µg/g Cr group for nephritis and nephrosis were 4.82 (95%CI 1.07 - 21.61) in men and 7.92 (95%CI 1.77 - 35.33) in women, respectively. The significant increase was not observed for malignant neoplasm.

CONCLUSIONThese results suggest a dose-response relationship between Cd body burden and mortality for cardiovascular diseases, cerebrovascular diseases and nephritis and nephrosis.
