BACKGROUND: Since the advent of cisplatin-based chemotherapy, the majority of metastatic testicular cancers can be cured by chemotherapy followed by retroperitoneal lymph node dissection (RPLND). However, postchemotherapy RPLND confers no therapeutic benefit if the residual mass contains no viable cells. Therefore, to determine which parameters predict a patient's likelihood of having only necrosis in the residual mass, we retrospectively analyzed clinical parameters of patients who underwent postchemotherapy RPLND. METHODS: Data from 27 patients with metastatic testicular cancer were analyzed. The histology of the primary tumor was seminoma in 11 cases and non-seminoma in 16 cases. All of the patients with non-seminoma showed a normalization of tumor markers after chemotherapy. Analysis of clinical parameters included data for the initial histology, pretreatment tumor marker levels, postchemotherapy retroperitoneal mass size, and the histology of the dissected RPLNs. RESULTS: Histological examination of dissected RPLNs showed residual tumor in 27% of seminoma patients and 38% of non-seminoma patients. In seminoma patients, no viable cells were found in all six patients with pretreatment lactate dehydrogenase (LDH) levels below 7.5 times the upper limit of normal, or in all five of the patients with postchemotherapy RPLNs less than 2.5 cm. In non-seminoma patients, no viable cells were found in nine of 10 patients with pretreatment alpha-fetoprotein (AFP) levels less than 2700 ng/mL, or in eight of nine patients with residual mass less than 2.5 cm. CONCLUSIONS: Both postchemotherapy RPLN mass size and pretreatment tumor marker levels are possible predictors for necrosis of the residual mass in testicular cancer patients. 相似文献

AIM: To evaluate the incidence, nature and prognosis of multiple primary malignancies involving renal cell carcinoma (RCC) in Japan. METHODS: Between 1975 and 1998, 319 patients underwent an operation for RCC at Hokkaido University, Sapporo, Japan. The incidence of other primary malignancies was determined and classified as antecedent, synchronous or subsequent. Follow-up was obtained by thorough chart review or telephone interview, and ranged from 0 to 276 months (median 49.0 months). To analyze the influence of other primary malignancies on prognosis, overall and cause-specific survival rates of the patients with an antecedent or synchronous malignancy were compared to the remaining patients. RESULTS: Of the 319 patients there was at least one other malignancy in 38 patients (12%). Four patients had two other malignancies. The other malignancies were antecedent in 13, synchronous in 19 and subsequent in 10 patients. Twenty-two patients had gastrointestinal cancer. In cases of antecedent or synchronous diagnosis of other primary malignancies, RCC was commonly incidental, small or low-stage. Multivariate analysis using Cox's proportional hazards model showed that, for overall survival, the presence of other antecedent or synchronous malignancies was the second most significant prognostic factor, following the pathological stage of RCC. CONCLUSIONS: In Japanese patients with RCC, the incidence of other primary malignancies was not uncommon and these malignancies contributed to the prognosis of these patients. Therefore, the malignant potential of individual tumors should be paid careful attention in the management of these patients. 相似文献

Background: Bleeding is one of the main symptoms of internal hemorrhoids. However, the conventional Goligher's classification of internal hemorrhoids does not consider the severity of bleeding. We intended to establish a useful method for evaluating internal hemorrhoids using a colonoscope that reflected the severity of the symptoms.
Methods: Using a colonoscope in the retroflexed and forward viewing position, 104 patients with symptomatic internal hemorrhoids were evaluated based on the criteria of range, form and red color signs (RCS). Range was determined by the circumferential distribution of internal hemorrhoids and scaled from 0 to 4. Form was determined by size and scaled from 0 to 2. The presence of RCS was also evaluated. Symptoms were determined by interview and scaled from 0 to 3. Patients were treated by endoscopic band ligation (EBL) and were examined endoscopically before and 4 weeks after the treatment.
Results: Before the treatment, range, form and RCS were significantly correlated to bleeding ( P < 0.01), and form was significantly correlated to prolapse ( P < 0.05). The endoscopic classification scores at 4 weeks after EBL improved significantly (range from 3.25 ± 0.05–0.56 ± 0.08 [ P < 0.01] and form from 2.81 ± 0.04–0.56 ± 0.07 P < 0.01).
Conclusion: The new endoscopic classification of internal hemorrhoids proved to be closely correlated to symptoms, particularly bleeding, and thus highly useful in evaluating the effectiveness of the treatment. 相似文献

Hypertrophic cardiomyopathy and dilated cardiomyopathy are two major clinical phenotypes of “idiopathic” cardiomyopathy. Recent molecular genetic analyses have now revealed that “idiopathic” cardiomyopathy is caused by mutations in genes for sarcomere components. We have recently reported several mutations in titin/connectin gene found in patients with hypertrophic cardiomyopathy or dilated cardiomyopathy. A hypertrophic cardiomyopathy-associated titin/connectin mutation (Arg740Leu) was found to increase the binding to actinin, while other dilated cardiomyopathy-associated titin/connectin mutations (Ala743Val and Val54Met) decreased the binding to actinin and Tcap/telethonin, respectively. We also reported several other mutations in the N2-B region of titin/connectin found in hypertrophic cardiomyopathy and dilated cardiomyopathy. Since the N2-B region expresses only in the heart, it was speculated that functional alterations due to the mutations cause cardiomyopathies. In this study, we investigated the functional changes caused by the N2-B region mutations by using yeast-two-hybrid assays. It was revealed that a hypertrophic cardiomyopathy-associated mutation (Ser3799Tyr) increased the binding to FHL2 protein, whereas a dilated cardiomyopathy-associated mutation (Gln4053ter) decreased the binding. In addition, another TTN mutation (Arg25618Gln) at the is2 region was found in familial DCM. Because FHL2 protein is known to tether metabolic enzymes to N2-B and is2 regions of titin/connectin, these observations suggest that altered recruitment of metabolic enzymes to the sarcomere may play a role in the pathogenesis of cardiomyopathies. 相似文献

Relationship between severity and symptoms of reflux oesophagitis in elderly patients in Japan 总被引:6,自引:0,他引:6
TORU MAEKAWA YOSHIKAZU KINOSHITA AKIHIKO OKADA HIROKAZU FUKUI SHINYA WAKI SAZZAD HASSAN YUMI MATSUSHIMA CHIHARU KAWANAMI KIYOHIKO KISHI TSUTOMU CHIBA 《Journal of gastroenterology and hepatology》1998,13(9):927-930
Since information concerning reflux oesophagitis in the elderly is limited, particularly in Japan, the severity and symptomatic profiles of reflux oesophagitis in elderly patients were investigated. One hundred and nineteen patients with reflux oesophagitis found among 2278 endoscopy cases between 1993 and 1996 were investigated in this study. The patients were divided into two groups, elderly and non-elderly. The severity of reflux oesophagitis was estimated by the Los Angeles classification. The presence or absence of typical symptoms (heartburn and regurgitation) was determined by interview. Reflux oesophagitis was not only more frequently found in the elderly group, but was more severe than in the non-elderly. Although the degree of manifestation of typical symptoms was similar between the elderly and the non-elderly with high-grade oesophagitis, the elderly patients with mild reflux oesophagitis were less symptomatic than the non-elderly. Mild reflux oesophagitis in the elderly may be missed due to its rarity of typical reflux symptoms and a substantial number of elderly persons might have subclinical reflux oesophagitis. 相似文献

This study attempted to determine whether patients with major depression and panic disorder could be differentiated by personality features, measured by the Munich Personality Test (MPT). One of the six MPT personality dimensions, `rigidity', was developed in relation to the `melancholic type of personality', which may be a specific personality feature of depressive subjects. We therefore hypothesized that the MPT might be sensitive to possible personality differences between patients with major depression and panic disorder. Sixty-six patients with major depression and 27 patients with panic disorder, taken from consecutive intakes at an outpatient unit, were compared in terms of six personality dimensions of the MPT. The results demonstrated that rigidity could significantly differentiate the two patient groups, even after the possible confounding effects on the personality assessments were statistically partialled out. The MPT was suggested to be powerful for describing distinctive personality features of depressive subjects from anxiety subjects. 相似文献

Renal involvement is a major complication of systemic lupus erythematosus (SLE) and occurs in 30-70% of patients with SLE. Lupus nephritis is classified into six classes (I-VI) by the International Society of Nephrology and Renal Pathology Society (ISN/RPS). Although nephrotic syndrome is commonly associated with diffuse (ISN/RPS class IV) or membranous (ISN/RPS class V) lupus nephritis, several reports have described nephrotic syndrome in adult patients with minimal mesangial lupus nephritis (ISN/RPS class I) or mesangial proliferative lupus nephritis (ISN/RPS class II). However, nephrotic syndrome in mesangial proliferative lupus nephritis has rarely been reported in children. Although the pathogenesis of nephrotic syndrome with mesangial lupus nephritis is incompletely understood, three potential mechanisms have been postulated including lupus nephritis itself, non-steroidal anti inflammatory drug (NSAID)-induced minimal change nephrotic syndrome (MCNS) and coincidental occurrence of MCNS. We describe here a child with mesangial proliferative lupus nephritis who developed MCNS. 相似文献

ABSTRACT. Okada, S., Seino, V., Kodama, H., Yutaka, T., Inui, K., Ishida, M., Yabuuchi, H. and Seino, Y. (Department of Pediatrics, Osaka University Hospital, Fukushima-ku, Osaka and The Third Division, Department of Medicine, University of Kobe, Kobe, Japan). Insulin and glucagon secretion in hepatic glycogenoses. Acta Paediatr Scand 68: 735, 1979.—Insulin and glucagon secretion was investigated in ten patients with hepatic glycogenosis, types I and III, in order to understand the relationship between hypoglycemia and pancreatic function. In all patients, both oral glucose tolerance and intravenous arginine infusion tests revealed hypoinsulinemia. Decreased urinary C-peptide levels with standard food intake also supported hypofunction of pancreatic beta cells. On the contrary, the normal secretion pattern of glucagon in both types indicated in the arginine loading test, intact alpha cells in the pancreas. Persistent hypoinsulinism, which is apparently an adaptation to hypoglycemia, could be an important cause of nutritional dwarfism in both types of glycogenosis. The usefulness of the measurement of urinary C-peptide, which evaluates the pancreatic function and provides management for normal body growth, is discussed. 相似文献
