Voluntary work in our hospital by women belonging to the Women's Division of the Agricultural Cooperatives Association (JA) in Nagano got started in 1973, when the hospital accepted the organized activity of the women. In the beginning, participants were mostly officials of the Women's Division, but later on, other people joined them. They formed a society of volunteers known as Aspara Kai. The voluntary activities are wide-ranging from those directly concerned with care of patients to collecting materials. They have played an important role as a bridge connecting health care to the community by telling people how things are going on in the hospital. Among the activities our hospital sponsors or supports, there are short courses in nursing care, health, mutual help and so on. Doctors and many other specialists on the hospital staff participate in these projects as volunteer lecturers. To enrich the content of these activities, we wish to join hands more tightly with the agricultural cooperatives and become a bearer of health care, medical service and welfare in the region. By carrying out our activities with a sense of unity, comprehensively and efficiently, we will be able to build a society of mutual aid.

We perfomed an aortic valve replacement and intraoperative plasma exchange with Cell Saver 4^® made by Haemonetics for removal of bilirubin. Diluted blood after cardiopulmonary bypass and suctioned blood (total volume 11, 300ml) was washed, concentrated and transfused. Plasma bilirubin level was decreased to 5.4mg/dl from 9.9mg/dl during operation. It was concluded that intraoperative plasma excange with Cell Saver 4^® was safe and effective technique for removal of bilirubin during open heart surgery.

Cor triatriatum is an uncommon congenital malformation in which the fibromuscular abnormal septum divides the atrium into two compartments. Generally it is used to mean cor triatriatum sinister in which the left atrium is divided into two lumens. In typical cor triatriatum, an abnormal fibromuscular septum divides a proximal chamber that receives the pulmonary vein from a distal chamber that communicates with the left atrial appendage and the mitral valve. Several hypothesis were proposed concerning the mechanism of the abnormal septation of the atrium, but no single hypothesis could explain all the cases convincingly. We report the successful surgical treatment of a 6-month-old male patient with the rare variant of the cor triatriatum with pulmonary hypertension. The left pulmonary vein and superior right pulmonary vein drained into an accessory chamber which opened to the right atrium through a sinus venousus type atrial septum defect. The left inferior pulmonary vein drained into the true lumen which opened to right atrium through the patent foramen ovale.

We performed coronary artery bypass operation on 258 patients from July 1974 to February 1993, of whom 10 underwent a total of 11 reoperations. These 10 patients were not significantly different from the other patients with respect to gender, coronary risk factors and number of grafts used in the first operation, aside from older age and lower LVEF. The interval between the two operations was <1 year (early) or about 10 years (late) in most instances. The most common reasons for reoperation were graft failure from technical problems in early and time-related alterations in graft and progression of original disease in late cases. The outcome of reoperation was less than satisfactory, with 2 operative deaths, IABP required in 5, reoperation for bleeding needed in 3 and severe sternal wound infection of the patent vein graft postoperatively, of which atheromatous debris released from the atherosclerotic vein graft was strongly suspected to be the cause. The old vein graft should be immediately ligated at the beginning of CPB in cases with diffuse atherosclerotic vein graft in which more than several years have passed since initial operation. In reoperation, arterial graft is preferable, especially GEA graft can be used advantageously even with a left thoracotomy approach. Bypass reoperation for occlusion of LAD or Cx should be performed by a left thoracotomy approach.

We investigated the effectiveness of hangekobokuto in alleviating dysphagia and aspiration pneumonia attributed to late­stage neurosyphilis. Our study subject, a 67-year-old man treated for his leg pain in our department, hoped this treatment would relieve his severe cough and sore throat. According to a neurological investigation and the analysis of blood and cerebrospinal fluid, his symptoms (swallowing disturbance and aspiration pneumonia in the lower lobes of both lungs) led to the diagnosis of cerebral bulbar paralysis caused by latestage neurosyphilis. The patient requested drug therapy ; thus, we prescribed 7.5 g/day of hangekobokuto, to be administered orally, based on his medical findings of qi stagnation and tan yin. Dysphagia was relieved one week after oral administration of hangekobokuto, and after three weeks, the patient's discomfort had almost disappeared. Moreover, aspiration pneumonia was also improved in his chest CT image finding. Late-stage neurosyphilis symptoms usually develop within 20 to 30 years of contracting syphilis, an infection caused by the bacterium Treponema pallidum. Symptoms may include a loss of swallowing reflex and cough reflex due to the paralysis of cerebral basal ganglia. However, hangekobokuto was found to increase the concentration of substance P released in the pharyngeal head and tracheal mucosa, and thus improve swallowing function. We conclude that hangekobokuto is a useful agent for alleviating the swallowing abnormality of late-stage neurosyphilis.

Crowned dens syndrome (CDS) is a pseudogout of the cervical vertebra, which shows calcification around the dens of the axis. We report a case of CDS that was successfully treated with daiobotampito and shimotsuto. An 83-year-old woman visited our clinic because of neck pain. She was diagnosed with CDS and was initially administered daiobotampito and eppikajutsuto. Her neck pain improved slightly, but recurred. She was then administered daiobotampito and shimotsuto, after which her neck pain disappeared. We considered that daiobotampito and shimotsuto were effective for this prolonged illness based on persistent stasis and blood deficiency according to her treatment course and laboratory findings.

PURPOSE: This study evaluated the availability of multi-directionally forged (MDF) titanium (Ti) as a component of removable partial dentures (RPDs). MDF-Ti remarkably improved the mechanical properties of RPDs due to its ultrafine-grained structure. MATERIALS AND METHODS: The wear resistance, plaque adhesion, and machinability of MDF-Ti were tested. As controls, commercially pure (CP) titanium was used for wear, plaque adhesion, and machinability tests. For wear resistance, the volume losses of the titanium teeth before and after wear tests were evaluated. Plaque adhesion was evaluated by the assay of Streptococcus mutans. In the machinability test, samples were cut and ground by a steel fissure bur and carborundum (SiC) point. An unpaired t-test was employed for the analysis of the significant differences between MDF-Ti and the control in the results for each test. RESULTS: Wear resistance and plaque adherence of MDF-Ti similar to those of CP-Ti (P>.05) were indicated. MDF-Ti exhibited significantly larger volume loss than CP-Ti in all conditions except 100/30,000 g/ rpm in machinability tests (P<.05). CONCLUSION Although the wear resistance and plaque adherence of MDFTi were comparable to those of controls, MDF-Ti showed better machinability than did CP-Ti. MDF-Ti could be used as a framework material for RPDs.

Although palliative sedation therapy (PST) is considered to alleviate intolerable and refractory symptoms in dying patients with advanced cancer, there have been few studies regarding the situation of tertiary cancer center. We conducted a retrospective survey of the medical records of the patients who died between April 2015 and March 2016 at the National Cancer Center Hospital in Japan. PST was conducted in 75 out of 431 patients (17.4%). The patient demographics were as follows: sex (male/female), 48/27; median age, 61 years (range 5-83; 11 patients (14.7%) were aged under 39 years); and primary sites were lung, 18 (24.7%)/ pancreas, 11 (14.7%)/ hematopoietic organs, 11 (14.7%)/ bones and soft tissues, 8 (10.7%)/ and the others, 27 (36.0%). The main target symptoms for PST were dyspnea (38, 50.7%) and delirium (30, 40.0%). The most commonly used sedative agent was midazolam (72, 96.0%). Continuous deep sedation was intended in 61 patients (81.3%) at the death. Median survival from the start of PST were 2 days (range 0-54). The differences between palliative care team (PCT) intervention group and control group were lower age (58 vs. 62.5, P=0.048) and uniformity of initial midazolam dose (5-12 vs. 9.6-25.2 mg/day). Distinctive feature in this study was large proportion of adolescent and young adult patients with rare cancers. PCT might have different approaches to sedation in comparison to non-PCT medical staffs.

Painful orthopedic diseases are sometimes aggravated because of weather changes ; this is referred to as meteorological pain. We report two cases of great occipital neuralgia (GON) due to traffic accident in patients whose pain was aggravated by weather changes. Case 1 involved a 41-year-old woman who developed lumbago and cervical pain following a traffic accident. Two months after the accident, she had irregular occipital pain. Three months after the accident, a great typhoon occurred, and she suffered from severe occipital pain since that morning. She was diagnosed with GON as meteorological pain and was administered goreisan ; her occipital pain then improved. Case 2 involved a 31-year-old woman who developed cervical pain following a traffic accident. Three months after the accident, she experienced severe occipital pain due to weather changes. She was diagnosed with GON as meteorological pain and was administered goreisan ; her occipital pain then improved. Goreisan is dramatically effective for GON as meteorological pain caused by cervical sprain.
