Clinical parameters that predict histology of postchemotherapy retroperitoneal lymph node mass in testicular cancer 总被引:2,自引:0,他引:2
MIZUKI ONOZAWA KOJI KAWAI TAKAHIRO YAMAMOTO SHIRO HINOTSU SADAMU TSUKAMOTO KAZUNORI HATTORI NAOTO MIYANAGA TORU SHIMAZUI HIDEYUKI AKAZA 《International journal of urology》2004,11(7):535-541
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

Coexistence of renal replacement lipomatosis with xanthogranulomatous pyelonephritis 总被引:1,自引:0,他引:1
YUKO SAKATA NOBUTAKA KINOSHITA HIROMI KATO YASUSHI YAMADA YOSHIKI SUGIMURA 《International journal of urology》2004,11(1):44-46
We report on a case of coexistence of replacement lipomatosis with xanthogranulomatous pyelonephritis (XGP) in the same kidney associated with staghorn calculi. A 63-year-old man was admitted to hospital complaining of a right abdominal mass. Computed tomography (CT) showed renal parenchymal atrophy with extremely increased perirenal fat. Right nephrectomy was performed. Postoperative diagnosis was renal replacement lipomatosis with XGP. Renal replacement lipomatosis and XGP have several similarities in terms of clinical background and CT findings. Sometimes it is difficult to differentiate them from malignant diseases. It is extremely rare that both conditions coexist in the same kidney. To our knowledge, only one such case has been reported. 相似文献

Background: In Japan a new long‐term care insurance (LTCI) system, the so‐called ‘Kaigo‐Hoken’, was started in April 2000. The present study analyzes the change in the type of destination after discharge from a senile dementia therapy ward before and after the implementation of LTCI at Fukuoka Prefectural Onga Hospital, Japan. Methods: The present study examines data from 199 inpatients discharged from the Fukuoka Prefectural Onga Hospital that had been diagnosed with dementia and met the DSM IV criteria for Alzheimer's type, vascular dementia or other type of dementia. For the purposes of comparison two periods were defined, ‘the first period’ was defined as the period from 1 April 1999 to 31 March 2000, before LTCI was implemented, while ‘the second period’ was defined as the period from 1 April 2000 to 31 March 2001, after LTCI had started. Subject data was analyzed on the basis of where the subject had resided pre‐admission and their destination after discharge using the following classifications: nursing home or geriatric care facility, hospitalization, home and death. Results: While the certification rate of inpatients regarding long‐term care increased slightly in the second period, no significant change was observed based on where the subject had resided pre‐admission and their destination after discharge between the first and second periods. Conclusions: While LTCI is essential for Japan, it is necessary that people with dementia in senile dementia therapy wards are encouraged to return to their homes under the care and support of LTCI. 相似文献

EFFECTS OF SEED SAPONINS OF THEA SINENSIS L. (RYOKUCHA SAPONIN) ON ALCOHOL ABSORPTION AND METABOLISM 总被引:3,自引:0,他引:3

We evaluated the effects of the seed saponins of Thea sinensisL. on alcohol absorption and metabolism in rats and mice. Anethanolic extract from the seeds of T. sinensis was orally administeredto the rats 1 hr before or 0.5 hr after administration of ethanol(2 g/kg), and the blood ethanol assayed 0.5, 1, 2, 3, and 4hr after ethanol administration. The ethanol level decreasedafter both pie- and post- administration of the extract. Theextract was further purified to obtain a saponin fraction whichwas orally administered to mice 1 hr before ethanol administration.Blood, liver, and stomach were obtained 0, 1, 3, and 6 hr afterethanol administration, and the ethanol, acetaldehyde, acetate,and acetone concentrations in each specimen were measured byhead space gas chromatography. The saponin fraction decreasedthe ethanol levels in the blood and liver but increased thatin the stomach five-fold over the control level, suggestinginhibition of alcohol absorption. The ethanol disappearancetime from the blood was shortened, suggesting the promotionof alcohol disappearance. The acetate and acetone levels wereunaffected. However, the acetaldehyde level decreased in theblood, liver, and stomach. The decreases in the ethanol andacetaldhyde levels in the liver suggested the protective effectsof the seed saponins on the liver. The saponins did not directlyinhibit hepalic alcohol dehydrogenase activity. The seed saponinsof T. sinensis seem to suppress alcohol absorption by slowinggastric emptying and by inhibiting absorption across the cellmembranes of the digestive tract. 相似文献

The clinicopathological features, the immunophenotype, and the presence of Epstein–Barr virus (EBV)-associated genomes and gene products were examined in 17 cases of CD30+ anaplastic large cell lymphoma (ALCL) of B-cell type. Microscopically, the 17 cases were divided into ten cases of the monomorphic type and seven cases of the pleomorphic type. EBV was detected in 6 of 17 cases (38 per cent) by RNA in situ hybridization (ISH) with EBV-encoded RNA (EBER1). EBER1+ cases consisted of two cases (20 per cent) of the monomorphic type and four cases (57 per cent) of the pleomorphic type. The five EBER1+ cases showed clonality of the EBV genome by Southern blotting, consistent with the presence of EBV in a monoclonal proliferation. The EBV-encoded latent membrane protein 1 (LMP1) was found in all six EBER1+ cases and EBV-encoded nuclear antigen 2 (EBNA2) was present in two cases by immunohistochemistry. No expression of LMP1 or EBNA2 was observed in the EBER1− cases. The EBER1+ cases had a tendency for a more favourable prognosis than the EBER1− cases. It is concluded that EBV has an association with CD30+ ALCL of B-cell type in the Japanese population studied, and especially with the large pleomorphic type. EBV infection may play a pathoaetiological role and may influence clinical behaviour. 相似文献

BACKGROUND: The purpose of the paper was to determine the risk factors for small-for-gestational-age (SGA) infants at full term, in Japan. METHODS: The study was conducted at four hospitals and clinics in the Tokyo metropolitan area. A retrospective review of 2972 mothers and their infants born from singleton pregnancies at any time during the years 2002 and 2003 was conducted. RESULTS: Of these women, 8.4% gave birth to SGA infants. The proportion of SGA infants was significantly higher among heavy smokers (>10 cigarettes/day; 13.7%, P < 0.01). The odds ratio (OR) for SGA decreased significantly in proportion to the pregnancy body mass index (OR, 0.89; 95% confidence interval [CI]: 0.84-0.94, P < 0.001). The OR of SGA for stratified maternal weight gain was 1.79 (95%CI: 1.24-2.58, P = 0.01) for weight gain < 8.0 kg; 1.16 (95%CI: 0.79-1.71, P = 0.45) for weight gain 8.0-10.0 kg; and 0.49 (95%CI: 0.3-0.78, P < 0.01) for weight gain >12 kg. CONCLUSION: The present study clearly confirms the detrimental effect of a low prepregnancy body mass index, low maternal weight gain and maternal smoking during pregnancy on the incidence of SGA infants. 相似文献
