This study was performed to evaluate management of cancer pain in 322 patients who were treated in our pain clinic between January 1986 and December 1997. For this purpose, the change in the number of cancer patients and the annual morphine consumption during the period in our hospital were investigated. We found that as morphine consumption increased, the number of cancer patients visited the pain clinic decreased. Although 90% of them who visited the pain clinic underwent neural block therapy before 1996, the parcentage dropped to only 79% in 1996 and 50% in 1997. The increasing rate of morphine consumption in our hospital was on a par with the national average between 1986 and 1996. The use of adjuvant drugs did not change throughout the 12-year period.
We believe the consumption of morphine is not enough. It is necessary for us to become more skilled in using narcotics for relief of cancer pain along the guidelines of the World Health Organization.

A successful surgical correction of an incomplete endocardial cushion defect (ECD) with an ostium primum defect in a 63-year-old man is reported. Incomplete ECD with ostium primum defect often causes severe heart failure in infancy. Reports of its surgical correction in elderly patients are few. The patient had upper abdominal discomfort and grade 1 mitral valve regurgitation. The preoperative diagnosis was complete ECD (Rastelli type A) because we misdiagnosed a leakage from a cleft between the left superior leaflet and the left inferior leaflet for a flow through a ventricular septal defect when we analyzed a preoperative left ventriculography. The importance of not misdiagnosing the leakage and echocardiography in preoperative diagnosis of ECD was therefore realized. The operative procedure involved patch closure of the ostium primum defect and mitral valve annuloplasty by Kay's procedure and the mitral valve regurgitation completely disappeared. The postoperative course was uneventful. The upper abdominal discomfort and cardiomegaly improved. If there is no severe dysfunction of other organs, surgical correction of incomplete ECD should be recommended even for elderly patients.

Purpose : The purpose of the present study was to examine the relationship between respiratory function and ADL/QOL among community-dwelling elderly requiring support or care.
Methods : The study included 87 elderly aged ≥65 years who were certified to require support (yousienn)or care (youkaigo)level 1-3 and who used day care at a rehabilitation center. We evaluated their respiratory, mental, physical, and swallowing functions. ADL, IADL, and QOL were estimated using a questionnaire. Spearman's rank correlation test and multiple regression analysis were used to examine correlations of the functions with ADL/QOL.
Results : Respiratory, physical, and swallowing functions showed statistically significant correlations with ADL/IADL/QOL. Multiple regression analysis showed that forced expiratory volume in 1 second and swallowing function were related to ADL, IADL, and QOL (SF8body & mental).
Conclusion : ADL and QOL were associated with respiratory function in elderly subjects requiring support or care. Our data suggested that pulmonary rehabilitation to enhance respiratory and swallowing functions in elderly requiring support or care may improve their ADL and QOL.

In this report, we describe three hemodialysis patients with carpal tunnel syndrome (CTS) that were successfully treated with Goshakusan, one of the well-known traditional Japanese herbal (Kampo) medicines.
Case 1 was a 77-year-old woman suffering from sleep disorder due to night pain in the bilateral forearms. Case 2 was a 66-year-old woman complaining of sleep disorder due to lancinating pain in right upper and lower limb. They had undergone surgical decompression procedures for CTS several times in the bilateral forearms. However, they still needed a periodical injection of glucocorticoid into the region of carpal tunnel for the relief from pain. Case 3 was a 54-year-old man, who has been suffering from the recurrence of numbness of the left fingers since surgical treatment for CTS.
We diagnosed that the symptom of CTS in those three patients may be due to kan-shitsu (damp-cold or interior cold with dampness), because all of them were anuric hemodialysis patients, who tend to easily acquire phlegm and dampness, and their symptom was partially relieved by warming the forearm and fingers. Therefore, they were prescribed an oral goshakusan extract formula to remove kan-shitsu. Soon after they started taking the formula, the intensity of their pain or numbness markedly decreased. Taken together, our report suggests that it is worth trying to remove kan-shitsu by Kampo medicines for the conservative treatment of CTS.

A 22-year-old woman had been treated with a Ross operation for aortic root aneurysm and aortic regurgitation 10 years previously. In the initial Ross operation, a handmade tri-leaflet conduit was used for the right ventricle outflow tract (RVOT) reconstruction. The conduit was prepared preoperatively, by sewing a folded 0.1 mm expanded polytetrafluoroethylene (ePTFE) membrane onto the luminal cavity of the 24 mm woven double velour vascular graft, thereby creating a tri-leaflet valve. During ambulatory follow up after discharge, dilation of the pulmonary autograft had been observed, and its maximal diameter reached 60 mm. Furthermore, preoperative a pressure study revealed a 25 mmHg pressure gradient between the right ventricle and the pulmonary artery. At the time of reoperation, we performed an aortic root replacement combined with RVOT conduit replacement. A 24-mm woven double velour vascular graft integrating a 21-mm On-X mechanical prosthesis was used for aortic root replacement. A handmade ePTFE tri-leaflet conduit, 26 mm in size, was used to replace the previous RVOT conduit. The operation was successful, and the postoperative course was uneventful. The explanted conduit was sent for microscopic examination, which revealed that the graft was covered by a fibrocollagenous membrane. On the contrary, no surface membrane was found on the ePTFE valve. Moreover the microscopic examination showed cystic medionecrosis of the pulmonary autograft. Both dilatation of the pulmonary autograft and RVOT conduit failure were successfully treated at the second operation. However this young patient will require follow-up of the mechanical prosthesis and RVOT conduit for the rest of her life.

In this report, we describe four hemodialysed patients with upper abdominal discomfort successfully treated with Heiisan, one of the known traditional oriental herbal medicine.Case 1 was a 61-year-old man suffering from upper abdominal discomfort after each meal even though daily taking some medicine for gastritis. Case 2 was a 45-year-old man, who has also been suffering from upper abdominal discomfort after breakfast and supper despite daily taking H₂-blocker. Case 3 was a 61-year-old man complaining of upper abdominal discomfort. He has had loss of appetite despite being treated with H₂-blocker and gastroprokinetic medication. Case 4 was a 69-year-old woman complaining of upper abdominal discomfort with dull pain before eating. She was diagnosed as chronic gastritis and healing stage of duodenal ulcer and prescribed H₂-blocker. However, this medicine did not work.We diagnosed that upper abdominal discomfort in all the patients came from shitsu-jya (pathogenic dampness) in hii (Spleen-Stomach functional unit), and treated them with Heiisan, which was popular to remove shitsu-jya in Hii. Their symptom disappeared soon after taking this medicine.It is also difficult for hemodialysed patients to control their weight due to anuria and they tend to easily gain the weight due to inappropriate eating and drinking, leading to shitsu-jya in such patients. Therefore, our reports suggested that Heiisan was good for hemodialysed patients to control various upper abdominal symptoms that might be caused by shitsu-jya in Hii.

A 62-year-old woman was admitted to a regional hospital for acute myocardial infarction. Emergency coronary angiography revealed occlusion of the first diagonal branch, and transesophageal echocardiography showed severe mitral regurgitation due to anterior papillary muscle rupture. She was transferred to our hospital in a state of cardiogenic shock despite the use of high-dose catecholamine and intra-aortic balloon pumping. We immediately performed mitral valve replacement. The patient's postoperative course was uneventful and she was ambulatory when transferred to another hospital on foot on postoperative day 19. Physicians should be aware that fatal anterior papillary muscle rupture may be caused by isolated occlusion of the diagonal branch.

A 58-year old man without Marfan syndrome was referred to our hospital for congestive heart failure due to severe mitral regurgitation. He had undergone sternal turnover with a rectus muscular pedicle for pectus excavatum 36 years previously. We were able to perform mitral valve repair via median sternotomy using a usual sternal retractor. There was no adhesion in the pericardium and the exposure of the mitral valve was excellent. We closed the chest in ordinary fashion without any problems in the fixation of the sternum or costal cartilage. There were no complications such as flail chest or respiratory failure.

BACKGROUND : Previous studies have suggested positive association between residents' workload and medical errors. However, few studies have investigated the possible associations between procedural errors, workload, and the individual characteristics of residents, including personality, mental state and job satisfaction.
OBJECTIVE : To explore possible associations of workload and individual characteristics of residents with their procedural error rates.
DESIGN : Prospective observational study based on a daily questionnaire.
PARTICIPANTS : Residents of postgraduate year 1 and 2.
MEASUREMENTS : Residents' workload (on-calls, work hours, sleep and napping hours), residents' physical and mental health state, personality inventory, and procedural error rate (defined as procedural error counts divided by overall procedural attempts).
RESULTS : On average, the residents (N=49) were responsible for 9.8 inpatients per day (range, 1.9-23.1), worked for 16.0 hours per day (range, 12.6-19.8), slept for 4.4 hours per day (range, 2.8-5.7), napped for 0.2 hours per day (range, 0-0.7), and experienced 1 overnight work shift every 7.2 days. The procedural error rate was 2.2 per 10 procedures (range, 0.4-5.0). Using a multivariable adjusted regression model, significant factors associated with lower error rates included : longer napping ; reflective personality ; better mental state ; higher job satisfaction ; and, less on-call frequency.
CONCLUSIONS : Procedural error of residents is positively associated with higher on-call frequency and inversely associated with napping, reflective personality, better mental state, and higher job satisfaction. For reducing procedural error among residents, improvement of modifiable factors, such as workload and mental health, is needed.
