An extremely rare case of a primary carcinoid tumor arising in a mature retroperitoneal teratoma is reported. A 53-year-old woman was admitted for further examination of an incidental retroperitoneal mass with calcification. Computed tomography scans demonstrated a tumor with fat, soft tissue and bone densities on the left renal hilum. Surgical excision of the tumor was performed with a preoperative diagnosis of retroperitoneal teratoma. The pathological diagnosis was mature teratoma, including all three germ layers. A carcinoid tumor was evident among teratoid tissues and it was thought to be a teratoma with malignant transformation. The patient did not have a carcinoid syndrome and had an uneventful recovery. She has been followed for 31 months with no recurrence. Carcinoid tumors rarely occur in teratomas of the ovary and the testis and, to our knowledge, this is the first case of carcinoid arising in a retroperitoneal mature teratoma. 相似文献

BACKGROUND: Although many factors have been reported as predictors of the recurrence of renal cell carcinoma (RCC), none of the factors are consistent among different studies. In the study presented here, the potential clinicopathological predictors of the recurrence of N0M0 RCC were examined. METHODS: A total of 201 patients who underwent nephrectomy for N0M0 RCC were examined to determine the pathological tumor stage (pT stage), pathological tumor grade of malignancy (tumor grade), symptoms, and tumor size. RESULTS: RCC recurred in 29 patients (14.4%), 50% of whom developed new tumors within 24 months after nephrectomy. The disease-free 3- and 10-year survival rates declined as the pT stage and tumor grade increased: these rates were, respectively, 98.6% and 86.5% for pT1a; 93.7% and 87.9% for pT1b; 100% and 100% for pT2; 78.6% and 58.0% for pT3a; and 88.9% and 16.7% for pT3b. Significant differences in the recurrence rate were noted between pT3 and pT1 or pT2, as well as between grade 3 disease and grade 1 or grade 2 tumors. Multivariate analysis showed that a combination of the pT stage, grade, and presence of symptoms was useful for predicting the recurrence of RCC. CONCLUSION: The present study showed that patients undergoing nephrectomy for N0M0 RCC should be followed-up carefully for 2 years postoperatively with special attention to high pT stage, high grade, and the development of symptoms. 相似文献

Abstract Recently in Japan, 'door-to-door sales' has become of concern because it has created numerous legal and social problems. In this paper, a 47 year old dissociative trance disorder case who presented with possession by God is discussed. Specific types of door-to-door sales is known to use superstition and folk beliefs as tools to lure customers. In this particular case, these religious factors seemed to have played an important role in the precipitation of the disorder and its presentation. In addition, the brain-washing environment observed in video lectures used in door-to-door sales seemed to play an important role in the development of the possessive state. We also performed social psychiatric analysis of the occurrence of the possessive state in a city area, which has been considered to develop within traditional culture. Phenomenological classification by one of the authors was useful for diagnosing underlying disorders in the possessive state. 相似文献

Nifekalant (NF), a pure K+ channel blocker developed in Japan, has been reported to be effective in the treatment of life-threatening ventricular arrhythmias. We studied its efficacy in 18 men and 4 women with out-of-hospital ventricular fibrillation (VF) admitted to our emergency department between August 2001 and March 2004. The number of DC shocks delivered for out-of-hospital VF, serum Na+ and K+ , arterial blood pH, and base excess were compared in 8 patients treated with NF, 0.3 mg/kg i.v. followed by a continuous intravenous (group N) versus 14 patients treated with lidocaine, 2 mg/kg, i.v. (group C). The two groups were similar with respect to their baseline characteristics. Sinus rhythm returned in 5 of 8 patients in group N versus 2 of 14 patients in group C (P < 0.05). These seven patients were admitted to the intensive care unit, though all died within 1 month. The results of this study suggest that NF may be effective in defibrillation of out-of-hospital VF, though controlled studies are needed to confirm our observations. 相似文献

Background and Aim: Epidemiological studies have shown that 10–48% of people in developed countries have gastroesophageal reflux disease (GERD) symptoms such as heartburn and acid regurgitation. The present study aimed to examine the prevalence of GERD symptoms and GERD in Japanese subjects.
Methods: A cross-sectional study of Japanese subjects who visited a clinic for a routine health check up was carried out. Subjects were asked to fill out a self-report questionnaire. GERD was defined as the presence of heartburn and/or acid regurgitation at least twice per week.
Results: Of the 6035 eligible subjects, 2662 (44.1%) reported having had heartburn and/or acid regurgitation during the past year: 124 (2.1%) daily, 275 (4.6%) twice per week, 773 (12.8%) twice per month and 1490 (24.7%) less than twice per month. Three hundred and ninety-nine (6.6%) subjects were diagnosed as having GERD and there was no relationship between the prevalence of GERD and either sex or age. The prevalence of bothersome GERD symptoms was significantly higher in subjects with GERD than in those without GERD.
Conclusion: Approximately 6.6% of Japanese have GERD and most persons with GERD described heartburn or acid regurgitation as bothersome. 相似文献

Abstract Sensitivity training (ST), which originated in the USA during the late 1940s, has been used as part of training seminars in Japanese corporations since the late 1950s. The possibility of negative psychiatric effects of ST, and especially its role in inducing psychiatric symptoms, is yet to be clarified. A case of a 41-year-old male company worker whose brief psychosis was induced by a sensitivity training seminar held by the company he worked for is presented. In reviewing the psychopathology of the case with records from the ST seminar, we found similarities between the patient's ST seminar and brainwashing situations. Specifically, the patient experienced severe conflict (of thought process) between his Christian beliefs and being labeled a coward at the seminar. We conclude that monitoring of the ST programs is crucial in order to ensure the psychological safety of ST participants in Japan. 相似文献

The parotid saliva test was performed in 146 subjects, including 48 patients with pancreatic disorders, 82 with nonpancreatic disorders and 16 healthy persons. The following results were obtained: 1. The salivary output as well as the maximum bicarbonate concentration and amylase content in the parotid saliva of patients with pancreatic disorders were significantly less than those of patients with nonpancreatic disorders. 2. An abnormal saliva test was found in 83.3% of the patients with the pancreatic disorders. 3. Comparison was made of the parotid saliva test with the pancreozyminsecretin test in regard to diagnostic reliability in 44 subjects, including 22 with pancreatic disorders and 22 with nonpancreatic disorders. The data indicated that, in this series, an abnormal parotid saliva test was 88.6% accurate in diagnosing pancreatic disorders, whereas positive pancreozyminsecretin was only 65.9%. 相似文献
