Abstract
When CD4(+) T cell-rich population appears in theinitial trial in induction cultures of humanautologous cytotoxic T lymphocytes (CTL), the cultureresults frequently in no or weak killing activity andtherefore usually be discarded as an ;unsuccessful'CTL induction culture. However, addition of theinitial CD4(+) T cell-rich population enabledefficient induction of the autologous CTL in theensuing trials. The CTL thus generated exhibitedstronger killing activities against autologous braintumor cells and ovarian tumor cells than previouslyobserved. This simple recycling of the primed butinert CD4(+) T cell-rich population for CTLinduction will promote clinical practice of adoptiveimmunotherapy of human tumors with autologous CTL.

Abstract
Diffuse esophageal spasm (DES) has been reported as a potential cause of dysphagia or chest pain; however, the patho-physiology of DES is unclear. The aim of this study was to examine the manometric correlates of dysphagia and chest pain in this patient population. All patients undergoing manometry at our institution are entered into a prospectively maintained database. After institutional review board approval, the database was queried to identify patients meeting criteria for DES (≥20% simultaneous waves with greater than 30 mm Hg pressure in the distal esophagus). The patient-reported symptoms and manometric data, along with the results of a 24-hour pH study (if done), were extracted for further analysis. Out of 4923 patients, 240 (4.9%) met the manometric criteria for DES. Of these, 217 patients had complete manometry data along with at least one reported symptom. Of the patients with DES, 159 (73.3%) had dysphagia or chest pain as a reported symptom. Patients reporting either dysphagia or chest pain had significantly higher lower esophageal sphincter (LES) pressure than patients without these symptoms (P= 0.007). Significant association was noted between reported dysphagia and percentage of simultaneous waves. Chest pain did not correlate with percent of simultaneous waves, mean amplitude of peristalsis, or 24-hour pH score. The origin of reported chest pain in patients with DES is not clear but may be related to higher LES pressure. Simultaneous waves were associated with reported dysphagia. Using current diagnostic criteria, the term DES has no clinical relevance.

Abstract
BACKGROUND Patients with gastric cancer who have positive cytologic results for cancer cells in peritoneal washings (CY1) have poor outcomes, even in the absence of other distant metastases. A standard treatment for such patients remains to be established. METHODS We conducted a phase II trial with the 2-year survival rate as the primary endpoint. Patients who had gastric cancer with CY1 status but no other residual disease received postoperative chemotherapy with S-1 (1M tegafur-0.4M gimestat-1M otastat potassium) at a daily dose of 80mg/m(2) for 4 weeks, followed by 2 weeks of rest. This cycle was continued until disease progression or intolerable adverse events. D2 dissection was the recommended surgical procedure; splenectomy could be omitted at the discretion of the surgeon. Accrual of 50 patients was planned, and a 2-year survival rate of more than 36% was needed to exceed the historical control. RESULTS Forty-eight patients were enrolled, among whom 47 were assessable for survival and 46 for adverse reactions. Median overall survival was 705 days, and progression-free survival was 376 days. The 2-year survival rate was 47%. Median time to treatment failure was 288 days. Neutropenia was the commonest > or = grade 3 toxicity (6 patients), and anorexia was the most frequent > or = grade 2 non-hematologic toxicity (10 patients). CONCLUSIONS Gastrectomy followed by S-1 monotherapy resulted in survival that surpassed historical data and can serve as an active control treatment for future trials in patients who have gastric cancer with CY1 status in the Far East.

Abstract
Malignant hyperthermia (MH) is a genetic disorder of skeletal muscle in susceptible individuals that is triggered by exposure to anesthetic agents, and can cause death. Mutations in the ryanodine receptor type 1 gene (RYR1) are associated with MH-susceptibility. MH is also triggered in susceptible individuals by severe exercise in hot conditions or by overheating in infants. Here, we report a case of a child, 2years, 9months of age, who was left in a car and exposed to a high environmental temperature. The child was suspected to have died of heat stroke by autopsy examinations. Postmortem mutation analysis revealed that the child possessed two distinct RYR1 mutations. Since each mutation had previously been identified in a separate MH-susceptible patient, MH-susceptibility with over-response to the environmental high temperature might have occurred in this child with RYR1 mutations. These findings suggest that a MH-susceptible case may have died with a presumed diagnosis of heat stroke at autopsy.

Abstract
The purpose of this study is to assess the long-term outcomes after surgical repair of intrathoracic stomach. Prospectively collected data was retrospectively reviewed. Patients underwent a phone questionnaire 1 year postoperatively to assess gastroesophageal reflux disease-related symptoms and surgical satisfaction. In addition, objective evaluation for integrity of hiatal hernia repair was undertaken either by esophagram or endoscopy. Any recurrence was considered a failure. Forty-one patients underwent surgical repair of a large paraesophageal hernia with intrathoracic stomach during the study period. Thirty-four patients underwent a laparoscopic repair, and seven patients underwent a transthoracic repair. An antireflux procedure was performed on 28 patients, and 13 patients had only hernia reduction and hiatal closure. In the laparoscopic group, two patients required conversion to open laparotomy, as one was unable to tolerate the pneumoperitoneum, and the other had mediastinal bleeding. Thirty-eight (93%) were available for 1-year follow-up. There were three (7.8%) recurrences, one requiring emergency transabdominal repair, and the other two being asymptomatic 1-cm recurrences. All patients report a high degree of satisfaction with surgery. There is a high incidence of short esophagus in patients with intrathoracic stomach. The surgical repair is safe and durable, with high patient satisfaction at 1-year follow-up.

Abstract
A subset of patients does not report improvement of symptoms or satisfaction after antireflux surgery. The aim of this study is to assess the effect of pre-existing depression as a factor in patient satisfaction and gastrointestinal quality of life index (GIQLI) outcomes after antireflux surgery. Patients undergoing antireflux surgery who had filled a preoperative quality of life score and had more than 1 year follow-up were included in this study. Based on available history and self-reported medication use, patients were divided in two groups: with depression (group A) and without depression (group B). Fifty-four patients with completed preoperative GIQLI questionnaire were contacted for this study; 32 (59%) patients completed the postoperative questionnaire. Seven patients (22%) had psychological disorder (group A) in the form of depression The GIQLI in groups A and B increased significantly from 64.4 +/- 17.3 and 89.6 +/- 18.6 to 88.6 +/- 23.7 (P < 0.001) and 102.2 +/- 18.6 (P = 0.02), respectively, after the surgery. There was significant improvement in the quality of life in patients after antireflux surgery based on the GIQLI assessment. This improvement was also reported in patients with history of depression.

Abstract
BACKGROUND AND PURPOSE Although radiation skin injuries associated with interventional radiology have been known as a critical issue, there are few reports mentioning direct measurement of the entrance skin dose (ESD). Thus, the purpose of this study was to clarify the regional distributions of ESDs in neurointervention. MATERIALS AND METHODS Using photoluminescence glass dosimeters (PLDs), we measured the ESDs in 32 patients with a median age of 61.5 years. Angiographic parameters, including exposure time, dose-area product (DAP), and the number of digital subtraction angiography (DSA) studies and frames, were recorded. The ESDs of operators were analyzed by the same method. RESULTS The maximum ESD of 28 therapeutic procedures was 1.8 +/- 1.3 Gy. Although the averaged ESD on the right temporo-occipital region was higher than that in other regions, disease-specific patterns were not observed. Statistically positive correlations were found between the maximum ESD and exposure time (r = 0.5283, P = .005), DAP (r = 0.7917, P < .001), the number of DSA studies (r = 0.5636, P = .002), and the number of DSA frames (r = 0.8583, P < .001). As for operators, ESDs to the left upper extremity were significantly higher than those to other regions. However, most of the ESDs were <0.2 mGy. Lead protective garments reduced the exposure doses to approximately one half to one tenth. CONCLUSION It was shown that the regional ESD could be measured by applying the PLD. This method should contribute to reducing the dose accumulation in patients as well as in operators.

Abstract
The objective of this study was to describe the correlation between changes in colonic motility and defecatory disorders in four experimental canine models, with an emphasis on denervation. Therefore, we constructed a model by dividing 20 healthy mongrel dogs into four groups, i.e. control, denervation, transection and anterior resection of the rectum (AR) (denervation plus transection), and focused on the correlation between colonic motility and defecatory disorders by counting the colonic migrating motor complexes (CMMCs) and colonic non-migrating motor complexes (CNMCs). Gastrointestinal and colonic contractile activities were continuously recorded on a computer with strain gauge force transducers. The dogs' feces were checked daily, and their consistency was recorded as normal, semisolid, or watery. Compared with the control group, the transection group showed elongation of the propagation time (P < 0.05), and the mean motility index of colonic contractile activity at C4 and C5 in the denervation group was greater than that in the control group (P < 0.05). The AR group showed three features of colonic motility: (i) elongation of the mean CMMC cycle (P < 0.05); (ii) shortening of the propagation time (P < 0.05); and (iii) increment of the number of CNMCs. Concerning fecal consistency, the AR group only showed watery diarrhoea. In conclusion, we revealed the existence of a correlation between defecatory disorders and changes in colonic motility. Increased knowledge among colorectal surgeons of the changes in colonic motility that occur following colorectal surgery is very important and could lead to the curtailment of defecatory disorders among patients.

Abstract
Mutations of the cardiac ryanodine receptor (RyR2) gene cause catecholaminergic polymorphic ventricular tachycardia, which sometimes results in a finding of sudden unexplained death (SUD) at autopsy. We found a novel mutation (V2321M) in exon 46 of the RyR2 gene in a SUD case. V2321M was localized in a highly conservative site of the RyR2 gene, but was not found in 400 reference alleles. We previously reported two SUD cases with R420W mutations in exon 14 of the RyR2 gene. We examined possible phenotypic characteristics of all three of these cases of SUD with the RyR2 gene mutations. All cases displayed mesenteric lymph node hypertrophy as well as tendencies for aortic narrowing. By contrast, only one of the 14 SUD cases without RyR2 mutations displayed these phenotypes. This study supports the concept that postmortem genetic testing of RyR2 mutations should be considered in autopsy examinations of SUD cases. It also raises the possibility that some cases with RyR2 mutations may display phenotypic changes in lymphoid and cardiovascular organs.

Abstract
2085 Background: This clinical pilot study is to investigate the safety, feasibility, plus clinical response of autologous formalin- fixed tumor vaccine (ATFV) in primary glioblastoma multiforme (GBM) patients. Methods: Eleven (8 recurrent and 3 initially treated) primary GBM patients were evaluated. AFTV was prepared from formalin-fixed tumor tissue or paraffin-embedded tissue and premixed with original adjuvant materials. A delayed-type hypersensitivity test (DTH) was performed before and after each course of ATFV treatment that comprised 3 vaccinations at a 5-site intradermal inoculation. In addition, immunohistochemical analysis of MIB-1, p53, and MHC class-I complex was performed on the tumor tissue to analyze the difference in the response to the treatment. Results: The treatment was well tolerated with only local induration and low-grade fever. Among the 11 patients, the best responses were 1 complete remission, 2 partial response, 1 no change, and 7 progressive disease. In this series, the median survival period was 7 months from the initiation of the AFTV treatment, and 3 of the 4 responders survived for more than 20 months after AFTV inoculation. DTH reactions, immunohistological analysis of p53 and MHC class-I complex, and patient status may be useful to predict the efficacy of this therapy. Conclusion: This study demonstrated that AFTV treatment is safe, feasible, and potentially beneficial. Further clinical investigation is highly desirable in order to improve the outcome of GBM patients. No significant financial relationships to disclose.

Abstract
BACKGROUND The usefulness of the anatomy-function-pathology (AFP) score was examined to evaluate its prediction of recurrence after laparoscopic fundoplication for erosive reflux esophagitis. METHODS Of the patients undergoing laparoscopic fundoplication for erosive reflux esophagitis of Los Angeles classification grade A or higher from December 1994 to December 2004, 107 who underwent preoperative barium esophagogram, pH monitoring, and endoscopy were selected as subjects. The AFP score was calculated by A, F, and P factor grades of the AFP classification. By comparing patients with and without recurrence, the usefulness of the AFP score for predicting recurrence was examined. RESULTS Reflux esophagitis recurred in seven patients. No significant difference in age, sex, or A or F factor was observed between the groups, whereas a significant difference was observed in the P factor (p = 0.008). On the other hand, the mean AFP score in the recurrence group was 16.9 +/- 5.3, whereas that in the nonrecurrence group was 8.9 +/- 5.3 (p = 0.0021). Among the patients with a score of 17 points or more (n = 23), recurrence was found in 6 patients (26%). On the other hand, among the patients with a score lower than 17 points (n = 84), recurrence was found in 1 patient, but not in the remaining 83 patients (1%). Sensitivity was thus 85.7% (95% confidence interval [CI], 42.1-99.6), and specificity was 83% (95% CI, 74.2-89.8). The positive predictive value was 26.1% (95% CI, 10.2-48.4), and the negative predictive value was 98.8% (95% CI, 93.5-99.9). Multiple logistic regression analysis was performed, and receiver operating characteristics curves were obtained. The area under the curve for the AFP score was 0.8457, whereas that for the P factor was 0.7907 (p = 0.0045), suggesting that the AFP score may more accurately predict recurrence than the P factor. CONCLUSION The AFP score may be useful for predicting postoperative recurrence. If surgery is performed when the AFP score is lower than 17 points, the likelihood of postoperative recurrence is expected to be very low.
