We report the successful repair of impending rupture of a pseudoaneurysm of the brachiocephalic artery (BCA) in a 70-year-old man. He had undergone a mediastinal tumor resection through a median sternotomy in 1995. Pathological examination revealed non-Hodgkin's lymphoma. Two years later, he underwent radiation therapy of 65 Gray for metastasis to the supraclavicular lymph nodes. On January 18, 2000, plastic surgeons planned to perform a pectoralis major musculocutaneous flap to repair a radiation skin ulcer. During the operation, the BCA was lacerated, possibly in an area of radiation tissue damage. We performed a prosthetic graft (10-mm Gelseal^TM) replacement of the BCA. The right subclavian artery had to be ligated. Postoperative digital subtraction angiography (DSA) showed excellent reconstruction of the artery. Magnetic resonance angiography of the brain showed a deficit in the anterior communicating artery and stenosis of the posterior communicating artery, which indicated that the reconstruction procedure was reasonable. Seven months later, on August 18, 2000, the patient was transferred to our hospital because of swelling of the right neck and oozing from the previous cutaneous wound. CT scan and DSA demonstrated the presence of a pseudoaneurysm of the proximal anastomosis site, which required emergency surgery. Before this third sternotomy, a saphenous vein graft was interposed between both external carotid arteries. Removal of the prosthetic graft and resection of the pseudoaneurysm were performed under mild hypothermia and cardiopulmonary bypass with left common carotid arterial perfusion. Then, the wound was closed completely using a left pectoralis major musculocutaneous flap. The postoperative course was uneventful and DSA showed good patency of the graft and intracranial arteries. The patient was discharged without neurological complications. We conclude that prior reconstruction of the carotid artery is a safe and effective procedure for patients with aneurysmal changes in the BCA, especially in the case of re-operation.

OBJECTIVES: Sarcopenia and osteoporosis affects activities of daily living and quality of elderly people. However, little is known about its impact on elderly locomotor diseases, such as osteoporotic vertebral fracture (OVF). There is no report investigating the influence of both sarcopenia and osteoporosis on outcomes of OVF. This study aimed to evaluate the clinical outcomes of OVF in elderly patients from sarcopenic perspectives. METHODS: This prospective study was conducted with 396 patients, aged 65 years or more, hospitalized for the treatment of OVF (mean age, 81.9 ± 7.1 years; 111 males, 285 females). The primary outcome was the Japanese Orthopaedic Association (JOA) score for lumbar disease (at first visit, hospital discharge, and 1 year after treatment) and Barthel index (at the same time and before hospitalization). The second outcome was living place after discharge. Susceptibility to sarcopenia and osteoporosis were evaluated and clinical results of conservative treatment were compared. RESULTS: Sarcopenia significantly affected Barthel index at first visit and discharge. Sarcopenia patients had significantly higher rate for discharge to nursing home and living in nursing home after 1 year than patients without sarcopenia. Osteoporosis significantly affected the JOA score at the first visit and the Barthel index before hospitalization, at the first visit, discharge, and after 1 year. Osteoporosis did not affect the living place at discharge and after 1 year. CONCLUSIONS: Sarcopenia and osteoporosis affected outcomes of conservative treatment for OVF; moreover, sarcopenia affected the living place of OVF patients at discharge and after 1 year.

OBJECTIVES: The prevalence of chronic low back pain (CLBP) increases with age and several mechanisms are involved in the development of CLBP, including osteoporosis; however, no associations with sarcopenia have yet been identified. METHODS: In total, 100 patients with CLBP and 560 patients without CLBP (nCLBP) aged over 65 years were studied. Skeletal muscle mass index (SMI) and percentage of body fat were evaluated using wholebody dual-energy X-ray absorptiometry. Sarcopenia was diagnosed when the relative SMI was more than 2 standard deviations below the mean in young adults. Thus, the cutoff value for sarcopenia was defined according to Sanada's Japanese population data. Paraspinal muscle cross-sectional areas of the lumbar multifidus and the erector spinae muscles were calculated using magnetic resonance imaging. RESULTS: Forty patients (40.0%) from the CLBP group and 149 (26.6%) from the nCLBP group met the criteria of sarcopenia. SMI was significantly lower and the body fat ratio was significantly higher in the CLBP group compared with the nCLBP group. Sarcopenic obesity was significantly observed in the CLBP group. Lumbar multifidus and the erector spinae muscle cross sectional area were significantly lower in the CLBP group. CONCLUSIONS: Elderly patients with CLBP have significantly lower skeletal muscle mass, and age-related mechanisms in sarcopenia are considered to be associated with chronic pain. Therapeutic procedures that are used to treat elderly aging muscle, including muscle strengthening and performance training, can possibly be a treatment for or used to prevent elderly CLBP.

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.

An adult male rufous turtle dove, Streptopelia (S.) orientalis (Aves: Columbiformes), was found dead in Yorii-machi Town, Osato District 369-1217, Saitama Prefecture, Japan, and subjected to necropsy. A large number of immobile hypopi (deutonymphs) of the hypoderatid mite, Hypodectes (H.) propus (Acarina: Hypoderatidae), were found individually encapsulated subcutaneously primarily in the adipose tissue. The mites were 1.43 mm in length and 0.44 mm in width on average, and had provoked mild inflammatory reactions that predominantly manifested as foamy macrophages and lymphoplasmocytes. PCR analysis using ribosomal DNA extracted from paraffin-blocked tissues produced a 240 bp band specific for hypoderatids. Based on the morphological features (distinct coxal apodemes, especially in the anterior portion) and PCR-based findings, the hypopi were identified as H. propus. To the best of our knowledge, this is the first case describing the subcutaneous mite H. propus in a rufous turtle dove, S. orientalis, in Japan. This study also highlights the use of paraffin blocks as a source of tissue DNA for molecular evaluation.

We have conducted acupuncture treatment for prevening the relapse of recurrent tonsillitis. We previously noted the effectiveness of this treatment in 121 of 239 patients treated in 1980, especially in elementary school children. In the present study, we compared the annual days of absence from school and the body dimensions of children with tonsillitis given acupuncture treatment with those having tonsillar hypertrophy chosen by a school study, although there is a question on the latter's propriety as a control group in a strict sense, in order to investigate the degree of spontaneous healing included in the preventive effects of acupuncture treatment on the relapse of recurrent tonsillitis.
By May 1983, our reseach was completed in 22 children with tonsillitis given acupuncture treatment and 19 with tonsillar hypertrophy not given such therapy. In children with tonsillitis given acupuncture treatment, the average annual days of absence from school before treatment was 14.0, which was more than that for all children in the S elementary school, and that in the year after treatment was 6.5, approximating that for all children in the school. In children with tonsillar hypertrophy not given acupuncture treatment, the average number of days of absence was close to that for all children in the S elementary school in both years.
Among 14 children with tonsillitis given acupuncture treatment, lower values of height and weight were noted in eight and 12 children, respectively, at the beginning of treatment, as compared with the national averages. The body dimensions of children with tonsillar hypertrophy not given acupuncture treatment were similar to the national averages. Of 14 children with tonsillitis given acupuncture treatment, an increase to a value exceeding the national average was observed with both the height and weight in six children, the height in two and the weight in one within the year after treatment.
The above results show that children with tonsillitis have a problem from the educational and developmental standpoint, even if they do not have a focal tonsil. We think that acupuncture treatment is worth attempting prior to tonsillectomy, although it is not so surely effective as tonsillectomy, when the severity of operative stress on the living body due to tonsillectomy and the burden of medical expenses and the load on the patient's family caused by hospitalization are taken into consideration.

Objective: To elucidate the patient characteristics and outcomes of emergency surgery for spinal metastases and identify risk factors for emergency surgery. Methods: We prospectively analyzed 216 patients with spinal metastases who underwent palliative surgery from 2015 to 2020. The Eastern Cooperative Oncology Group performance status, Barthel index, EuroQol-5 dimension (EQ5D), and neurological function were assessed at surgery and at 1, 3, and 6 months postoperatively. Multivariate analysis was performed to identify risk factors for emergency surgery. Results: In total, 146 patients underwent nonemergency surgery and 70 patients underwent emergency surgery within 48 hours of diagnosis of a surgical indication. After propensity score matching, we compared 61 patients each who underwent nonemergency and emergency surgery. Regardless of matching, the median performance status and the mean Barthel index and EQ5D score showed a tendency toward worse outcomes in the emergency than nonemergency group both preoperatively and 1 month postoperatively, although the surgery greatly improved these values in both groups. The median survival time tended to be shorter in the emergency than nonemergency group. The multivariate analysis showed that lesions located at T3–10 (p = 0.002; odds ratio [OR], 2.92; 95% confidence interval [CI], 1.48–5.75) and Frankel grades A–C (p < 0.001; OR, 4.91; 95% CI, 2.45–9.86) were independent risk factors for emergency surgery. Conclusion Among patients with spinal metastases, preoperative and postoperative subjective health values and postoperative survival are poorer in emergency than nonemergency surgery. Close attention to patients with T3–10 metastases is required to avoid poor outcomes after emergency surgery.
