A 55-year old man was admitted to our hospital owing to endograft collapse after TEVAR. He had undergone total arch replacement for acute aortic type A dissection at age 39, and undergone thoracic endovascular aortic repair (TEVAR) for chronic aortic type B dissection at age 54. TEVAR was successfully performed and the false lumen was shrunk. However, one year after TEVAR, computed tomography showed endograft collapse. Technical success was not achieved by the balloon technique to treat endograft collapse, so we performed additional TEVAR. After this procedure, endograft collapse was repaired. The postoperative course was uneventful.

We report the findings in a 75-year-old woman who was given diagnosis of rupture of the internal thoracic artery (ITA) and was successfully treated by coil embolization. The patient suddenly felt chest pain, and a chest CT revealed a mediastinal hematoma. She was suspected to have an acute aortic dissection, and therefore transferred to our hospital. Upon careful examination, a CT showed a hematoma in the superior mediastunum and the extravasation of the left internal thoracic artery. Emergency coil embolization was thus performed to stop the bleeding. After the embolization, no further hemorrhaging was observed. The patient was uneventfully discharged in a healthy state 2 weeks later. Rupture of the internal thoracic artery is rare. However, it is important to include this potential disease in the differential diagnosis when encountering a patient presenting with an atraumatic mediastinal hematoma.

The method of cardioplegic myocardial protection is often controversial for re-cardiotomy after a coronary artery bypass grafting (CABG). A 69-year-old woman with a history of three previous surgeries consisting of closed mitral commissurotomy (CMC), dual valve replacement (DVR), and CABG underwent mitral valve replacement (MVR) and CABG for perivalvular leakage (PVL). As a result, the bilateral coronary ostium and the bypass graft to the right coronary artery (RCA) were totally occluded. The left internal thoracic artery (LITA) graft to the left anterior descending (LAD) coronary artery was the only inflow to the left coronary artery system and the right coronary artery system developed collateral inflow. Cardioplegia was carried out by performing a temporary anastomosis graft on the saphenous vein graft (SVG) in the left anterior descending coronary artery and a new bypass graft in the RCA was used for the administration of cardioplegic solution with no complications. There are various strategies for cardioplegic myocardial protection. The best method should be selected depending on the patient characteristics and condition.

Chromosomal loss of heterozygosity (LOH) is a common mechanism for the inactivation of tumor suppressor genes in human epithelial cancers. LOH patterns can be generated through allelotyping using polymorphic microsatellite markers; however, owing to the limited number of available microsatellite markers and the requirement for large amounts of DNA, only a modest number of microsatellite markers can be screened. Hybridization to single nucleotide polymorphism (SNP) arrays using Affymetarix GeneChip Mapping 10 K 2.0 Array is an efficient method to detect genome-wide cancer LOH. We determined the presence of LOH in oral SCCs using these arrays. DNA was extracted from tissue samples obtained from 10 patients with tongue SCCs who presented at the Hospital of Tokyo Dental College. We examined the presence of LOH in 3 of the 10 patients using these arrays. At the locus that had LOH, we examined the presence of LOH using microsatellite markers. LOH analysis using Affymetarix GeneChip Mapping 10K Array showed LOH in all patients at the 1q31.1. The LOH regions were detected and demarcated by the copy number 1 with the series of three SNP probes. LOH analysis of 1q31.1 using microsatellite markers (D1S1189, D1S2151, D1S2595) showed LOH in all 10 patients (100). Our data may suggest that a putative tumor suppressor gene is located at the 1q31.1 region. Inactivation of such a gene may play a role in tongue tumorigenesis.

Objective:
BRCA1 and BRCA2 mutation carriers are recommended to undergo risk-reducing salpingo-oophorectomy (RRSO) by age 40 and 45, respectively. However, the carriers have a different way of thinking about their life plan. We aimed to investigate the distribution of age at diagnosis of ovarian cancer (OC) patients to examine the optimal timing of RRSO in the carriers.
Methods:
We examined a correlation between age at diagnosis of OC and common mutation types in 3,517 probands that received BRCA genetic testing. Among them, germline BRCA1 mutation (gBRCA1m), germline BRCA2 mutation (gBRCA2 m) and germline BRCA wild-type (gBRCAwt) were found in 185, 42 and 241 OC patients, respectively.
Results:
The average age at diagnosis of OC in gBRCA1m and gBRCA2 m was 51.3 and 58.3 years, respectively, and the difference from gBRCAwt (53.8 years) was significant. The gBRCA2 m carriers did not develop OC under the age of 40. The average age was 50.1 years for L63X and 52.8 years for Q934X in BRCA1, and 55.1 years for R2318X and 61.1 years for STOP1861 in BRCA2 . The age at diagnosis in L63X or R2318X carriers was relatively younger than other BRCA1 or BRCA2 carriers, however their differences were not significant. With L63X and R2318X carriers, 89.4% (42/47) and 100% (7/7) of women were able to prevent the development of OC, respectively, when RRSO was performed at age 40.
Conclusion
There appears to be no difference in the age at diagnosis of OC depending on the type of BRCA common mutation. Further analysis would be needed.

The purpose of this study was to clarify the number of types and frequencies of fundamental movement patterns (FMP) during Soccer Kids Program (SKP) recommended by the Japan Football Association for preschool children, and to clarify the relationship between FMP and Moderate to Vigorous Physical Activity (MVPA; ≥3 METs). The participants were 12 children (six boys and six girls). The SKP was conducted for 50 minutes with video recording, and researchers counted the number of FMP during SKP by replaying the video. The FMP during SKP was classified into three movement categories: stability (eight types), locomotion (eight types), and manipulation (18 types). The participants wore a triaxial accelerometer (Active Style Pro, OMRON) on their waist during SKP and measured their activity (intensity and step) every ten seconds. Partial correlation analysis was performed on the relationship between MVPA and FMP using age in months and gender as covariates. MVPA during SKP was 24.3±5.0 minutes (48.7%), which was considerably more than in previous studies. Total number of FMP during SKP was 637.8±183.5 (stability: 27.8±12.4, locomotion: 399.7±156.6, manipulation: 210.3±48.4) and the mean number of types of FMP was 14.6±2.0 types. The FMP was confirmed in all three categories. There were significant correlations between MVPA and the total FMP (r = 0.72), the number of stability (r = 0.83), and the types of FMP (r = 0.69). This study suggested that an association between MVPA and FMP (total FMP, total stability, and type of FMP) in SKP.

PURPOSE: Deciding on treatment carcinoma of the tongue when the tumor has a thickness of 1.5 cm or more is difficult. Surgery often requires wide resection and re-construction, leading to considerable functional impairment. A cesium implant is an attractive option, but according to the Manchester System, a two plane implant is needed. MATERIALS AND METHODS: According to the textbook, a tumor is sandwiched between the needles, which are implanted at the edge of the tumor. This may cause an unnecessarily high dose to the outer surface of the tongue, which sometimes leads to a persistent ulcer. To avoid this complication, we invented a modified implantation method, and applied the method to five consecutive patients. RESULTS: With a minimum follow-up of 2 years, all primary tumors in 5 consecutive patients have been controlled. No complications occurred in soft tissue of the tongue or in the mandible. CONCLUSION: Our modified Manchester System was feasible and effective for tumors that has a thickness of 1.5 cm or more.

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.

We reported nine cases of metastatic skin carcinoma experienced at the Department of Dermatology, Obihiro Kosei Hospital during the period from April 1991 to March 1993. Lung was the most common primary lesion (four out of nine cases), followed by uterus (two) and stomach, breast, and kidney (one each). The clinical features of the metastases were classified into nodular (five cases), inflammatory (one case) and sclerotic (three cases) types. Peculiar zoster-like inflammation was seen in metastatic gastric cancer. Pathologically, adenocarcinoma was more common than squamous cell carcinoma. The average interval between the diagnosis of the primary cancers and the development of the skin metastases was about 30±25 months. The average life span after the detection of the skin metastases was 6.8±5.6 months. Poor prognosis of skin metastasis was thus reconfirmed.

Objective: To develop an effective and safe therapeutic strategy, we studied the effect of the clinical characteristics of patients with acute drug intoxication on the duration of hospitalization.
Subjects and Methods: The subjects were 89 patients hospitalized for acute drug intoxication. They were divided into two subgroups; the short hospitalization group (duration of hospitalization < 7 days) and the long hospitalization group (duration of hospitalization ≥ 7 days). We compared age, sex, vital signs, drugs, and therapy between the two groups.
Results: There were no significant differences in sex or severity of consciousness disturbance between the short- and long-hospitalization groups. Age in the latter group was higher than that in the former, and age was significantly and positively correlated with the duration of hospitalization. Prolongation of hospitalization in patients with Japan Coma Scale (JCS) I or II is associated with psychiatric disease, and in patients with JCSIII, with physical disease. We used direct hemoperfusion (DHP) to treat patients with severe acute drug intoxication. The duration of hospitalization in patients treated by DHP tended to be shorter than those not so treated.
Conclusions: The present results suggest that aging is associated with prolongation of hospitalization and the onset of physical disease among patients with acute drug intoxication. When elderly patients with acute drug intoxication are treated in a primary-care setting, the question of whether or not physical diseases are present as complications should be considered. The appropriate use of DHP for the treatment of patients with severe acute drug intoxication requires further study.
