Cystadenoma is an uncommon benign epithelial neoplasm. Cystadenoma usually occurs on the palatal and buccal mucosa, but is less commonly found in the retromolar regions.A 43-year-old male patient noticed a swelling on his gingiva distal to the right mandibular second molar. Physical examination showed a diffuse poorly circumscribed swelling extending from the lingual gingiva distal to the right mandibular second molar to the floor of the mouth and pharynx. The tumor size was 20 x 27 mm. The surface mucosa was purply-blue in parts. About 4 ml of pale yellow serous fluid was aspirated. The tumor was surrounded by a capsule and was excised successfully above the periosteum, incorporating a 2 mm safety margin including the surface mucosa. The tumor consisted of a fibrous capsule with multiple cystic cavities of various sizes. The cysts were lined by a layer of columnar epithelium, with intracystic papillary proliferation in some areas. No cytologic atypia or invasion of the surrounding tissues were observed.There is no evidence of recurrence ten years after excision, suggesting that complete excision is sufficient treatment in such cases.

This study aimed to investigate the effects of Ball Exercise on physical functions related to fall prevention among community-dwelling elderly. Nineteen healthy elderly women voluntarily participated in a Ball Exercise course that consiste of 60-min classes once a week for three months. We assessed their physical functions at baseline and then again after the Ball Exercise course. Significant improvements (p<0.05) were observed in one leg standing without vision (+7.2 s), functional reach (+14.4%), trunk flexibility test (+7.1%), maximum walking speed (+17%), and the isometric muscle strength of the knee and ankle joints (+9.8〜35.7%), but no changes were observed in grasping power. This study suggested that Ball Exercise might be a suitable fall prevention and health promoting exercise for elderly people. We therefore concluded that ensuring a high level of physical functions is important to prevent falls and maintain a high quality of life for elderly people.

The purpose of this study was to analyse electromyographic characteristics of Tai Chi. The subjects, six healthy men, performed ; (1) the maximum voluntary contraction (MVC) of each tested muscle ; (2) three forms in 24-style Tai Chi ; (3) on a bicycle ergometer (100 w) and jogging (120 m/s). For each muscle, the maximum integrated EMG for one second was computed and standardized by MVC(%MVC). The results were as follows : (1) High muscle activity was observed during Tai Chi. In five muscles, the %MVC exceeded 60%. (2) In the rectus femoris m., the %MVC of Tai Chi was 6.8 times that of the bicycle ergometer and 10.3 times that of jogging (p<0.01). In a similar way, in the tibialis anterior m., the %MVC was 7.1 and 4.8 times (p<0.01), and in the rectus abdominis m., the %MVC was 6.3 and 4.9 times (p<0.01). We conclude that Tai Chi might be useful as an exercise in muscle strength training.

Two cases of secondary oral squamous cell carcinoma (SCC), which developed in recipients of hematopoietic stem cell transplantation (HSCT) for leukemia, are reported. The first patient underwent allogeneic HSCT for chronic myelogenous leukemia at 32 years of age. He suffered from chronic graft-versus-host-disease (GVHD) of the oral mucosa after HSCT, and has subsequently received immunosuppressive therapy. He experienced metachronous multiple SCCs in the maxillary gingiva and the dorsum of the tongue at 36 years and 40 years of age, respectively. The second patient received autologous HSCT for acute myelogenous leukemia at 22 years of age, and she did not experience GVHD after transplantation. SCC developed in the lateral border of the tongue at 27 years of age. PCR analysis detected both HPV16 and HPV18 in the tongue tumor of the first patient, and only HPV18 in that of the second patient, suggesting that the infection of high-risk HPVs was possibly involved in the development of post-HSCT oral cancers in these patients. Since risk factors for post-HSCT oral SCC are not yet well recognized, long-term close follow-up is necessary for the early detection of secondary oral cancers in all transplant recipients.

A 59-year-old man was admitted for treatment of Stanford type B acute dissecting aneurysm with acute renal failure. He had begun hemodialysis one month after onset, because digital subtraction angiography (DSA) revealed that the truelumen was narrowed by a dilated false channel just above the renal artery. Initially axillo-femoral bypass was performed to treat renal failure, and the patients was easily weaned from hemodialysis. Eight months after the first operation, descending thoracic aorta replacement was performed. The patient is doing well one year after operation. In conclusion, axillo-femoral bypass yielded good results because our patient recovered from renal failure and could undergo radical operation safely. Axillo-femoral bypass allowed evaluation of the hemodynamic study before radical operation.

Introduction: The purpose of this study was to clarify the relationship between the available service information on small-scale multifunctional in-home nursing care (KANTAKI) and its operational status via text mining.Methods: We obtained nationwide textual information on KANTAKI from the Nursing Care Service Information Disclosure System and the Ministry of Health, Labour, and Welfare, and analyzed the characteristics of the word usage using KH Coder. The number of users and employees and the implementation of services were compared among the facilities that used terms relating to medical dependency and end-of-life care, which are KANTAKI characteristics, and with other facilities.Results: The facilities that used terms relating to medical dependency and end-of-life care showed significantly more users requiring nursing care level 5 and more full-time nursing staff than those not using such terms. Moreover, regarding service provision, the rate of procedures was significantly higher in 11 of 12 items, except for stoma.Conclusion: The facilities that use terms relating to medical dependency and end-of-life care in their information have more users and provide a greater variety of services. In the future, educational support is required to enable facility managers to understand the services and translate them into their work.

BACKGROUND: In Japan, there have been few reports about drug compliance, which is an important determinant of effectiveness, in the management of bronchial asthma patients. To clarify drug compliance and its relationship with various aspects of asthma management, a questionnaire survey was performed on asthmatic patients and their pharmacists.
METHODS: This survey was carried out, from October to November in 2001. The subjects were limited to the regular inhaled corticosteroid (ICS) users, and were restricted to patients whose medication had not been changed for at least 6 months before the survey. The questionnaires inquired about asthma status, various factors that have been reported to be associated with drug compliance and asthma management. Patients' pharmacists were asked about prescribed medications and drug compliance based on the pharmaceutical records.
RESULTS: Completed questionnaires were received from 610 patients. ICS compliance was not lower than that of anti-allergic drug but lower than that of oral sustained-released theophylline (OSRT) . Multiple regression analysis revealed a significant correlation between ICS and OSRT compliance.
CONCLUSION: These results might suggest that OSRT could improve patient's compliance to drug therapy through its bronchodilatory effect, thus resulting in better compliance to ICS. If this were the case, OSRT would play an important role in asthma management.

BACKGROUND: Following the increase in the number of children with food allergies, support systems are now required for school lunches, but a large-scale factual investigation has not been carried out. OBJECTIVE: We evaluated the features of elimination diet due to food allergy and the support system in kindergartens and schools. METHODS: A prefecture-based questionnaire survey regarding measures for food allergies in school lunches of all kindergartens, public elementary schools, and public junior high schools (631 facilities) was conducted in Oita Prefecture, Japan. RESULTS: The recovery rate of the questionnaire was 99.5%, which included 106,008 students in total. A total of 1,562 children (1.5%) required elimination diets. The rate of children on elimination diets in kindergartens and elementary/junior high schools that required medical certification by a physician was 1.2% (324 among 27,761 children), which was significantly lower than the 1.8% of children (1,227 among 68,576 students) on elimination diets at the request of guardians without the need for medical certification (p < 0.0001). A total of 43.9% of the kindergartens and schools said that they would contact guardians if symptoms were observed after accidental ingestion, while a low 8.1% stated that they provided support to children themselves, including the administration of adrenaline auto-injectors. CONCLUSION: Medical certification reduces the number of children requiring elimination diets, but it has not been adequately implemented. Furthermore, waiting to contact guardians after symptoms are observed may lead to the delayed treatment of anaphylaxis. Cooperation between physicians and teachers is desired to avoid the overdiagnosis and undertreatment of children with food allergies.

The first case was a 67-year-old woman. She had been given a diagnosis of fulminant myocarditis and received a biventricular assist device as a bridge to recovery. A Nipro ventricular assist device (VAD) was implanted into her left heart. She was also found to have moderate aortic insufficiency before the operation, so she received aortic valve replacement (AVR) with a bioprosthetic valve (CEP Magna Ease 21 mm) at the same time. Her cardiac function recovered gradually. Therefore, a weaning operation was scheduled for three months after the VAD implantation. However, her left ventricle motion was very poor when she was taken off of the extracorporeal circulation after removing the VAD, and transesophageal echocardiography (TEE) revealed severe bioprosthetic valve stenosis. When her heart was stopped again and the bioprosthetic valve was observed, the leaflets of the bioprosthetic valve were fused. Commissural fusion of bioprosthetic valve was able to be released using forceps, and the punnus extending under the leaflet was removed. In this way, the function of the bioprosthetic valve was restored. Her cardiac motion became good, and removal from extracorporeal circulation was easily achieved. She left the hospital 100 days after weaning from the VAD. The second case was a 68-year-old woman. She also had fulminant myocarditis. She underwent biventricular assist device implantation and AVR (CEP Magna Ease 19 mm). Her cardiac function recovered, and a weaning operation was scheduled on the 73rd-postoperative day. Preoperative TEE before the weaning of VAD showed severe bioprosthetic valve stenosis. The commissural fusion of the bioprosthetic valve was released and the punnus extending under the leaflet removed at the same time as the VAD was removed. Re-valve replacement was not required. We should therefore consider the possibility of bioprosthetic valve stenosis when VAD implantation and AVR with a bioprosthetic valve are performed at the same time in patients with an extremely reduced cardiac function.
