Objective: This study examined the relationship between bothersome symptoms of nocturia and erectile function. Methods: Subjects comprised patients with lower urinary tract symptoms (LUTS) suggestive of benign prostatic hyperplasia (BPH). Patients were prospectively followed on treatment with the alpha‐1 blocker naftopidil for 8 weeks. Patient backgrounds and efficacy of naftopidil associated with LUTS and sexual activity were evaluated. Results: The percentage of patients who identified nocturia as the most bothersome symptom was 30.2% (n = 135), representing the highest percentage among International Prostate Symptom Score (IPSS) items. The number of patients with nocturia as the most bothersome symptom plateaued at an IPSS for nocturia of two or three points. In contrast, the number of patients with slow stream as the most bothersome symptom increased with symptom severity according to IPSS for slow stream. Logistic regression analysis on association between nocturia and erectile function confirmed that the odds ratio was 1.41 (P < 0.05). Naftopidil showed excellent efficacy related to male LUTS, but International Index of Erectile Function 5 (IIEF5) total score was almost unchanged. Among patients with nocturia improved by naftopidil, IIEF5 total score was significantly changed in the group with IPSS nocturia score ≤1 as compared to the group with IPSS nocturia score ≥2 per night (P = 0.038). Conclusion: Nocturia the most bothersome symptom correlated with aging. Nocturia could associate erectile dysfunction, and keeping the frequency of nocturia at ≤1 episode might be meaningful for maintaining quality of life in elderly men. 相似文献

SUMMARY: A 73-year-old man who had been undergoing chronic haemodialysis (CHD) for 3 years developed haemophagocytic syndrome (HPS) that might have been triggered by Epstein-Barr virus (EBV) infection. the patient finally died of miliary tuberculosis (TB) reactivation that promoted the progression of HPS. Immunological abnormalities in patients undergoing CHD may be notable. the early diagnosis of TB reactivation may be important for reducing the mortality in cases of HPS, as a high incidence of TB is encountered in patients undergoing CHD. In contrast, the simultaneous occurrence of an EBER-positive hybridization signal with T cell-specific immunolabelling of CD45RO cells was well detected in the spleen and lymph nodes, and interferon gamma was elevated in the serum. These findings coincide with the reported preferential expansion of T cells rather than B cells in EBV infection, and support the hypothesis that systemic hypercytokinaemia caused by the proliferation of EBV-infected T cells may play a crucial role in the development of HPS. 相似文献

We describe a very rare case of synchronous granular cell tumor of the bladder, endometrial carcinoma and endometrial stromal sarcoma. A 55‐year‐old woman with a 4‐month history of genital bleeding was cytologically diagnosed with endometrial carcinoma. Imaging studies suggested concomitant bladder tumor with the possibility of direct invasion from endometrial carcinoma. Total abdominal hysterectomy with bilateral salpingo‐oophorectomy and transurethral resection of bladder tumor was performed. The bladder tumor comprised polygonal cells with abundant eosinophilic, finely granular cytoplasm, separated by collagenous tissue. Neither nuclear pleomorphism nor tumor necrosis was found. Immunohistochemical expression of neural markers of neuron‐specific enolase and S‐100 allowed the diagnosis of granular cell tumor (GCT) of the bladder. Microscopic examination of endometrium revealed endometrioid adenocarcinoma with squamous differentiation (EAC). Ill‐defined nodular lesion comprising endometrial stromal sarcoma (ESS) was accidentally found in myometrium. Postoperatively, the patient underwent radiotherapy. This is the first well‐documented case of synchronous triple tumors comprising GCT of the bladder, uterine EAC and ESS. 相似文献

Host immunity has been suspected of playing a role in recurrent herpes simplex. In this preliminary ultrastructural study of two patients with acute herpetic eruption, it was noted that the keratinocytes exhibiting the most severe damage are those adjacent to large granular lymphocytes. In contrast, many keratinocytes filled with viral particles of herpes simplex show little or no signs of keratinocyte damage. These observations suggest that in recurrent herpes simplex the epidermal damage may be due, at least in part, to cell-mediated host immunity as well as to the viral infection. 相似文献

A cytogenetic study of 1000 spontaneous abortions 总被引:2,自引:0,他引:2
T. HASSOLD N. CHEN J. FUNKHOUSER T. JOOSS B. MANUEL J. MATSUURA A. MATSUYAMA C. WILSON J. A. Yamane P. A. JACOBS 《Annals of human genetics》1980,44(2):151-164
Cytogenetic analysis of 1000 spontaneous abortions showed 463 to have an abnormal chromosome constitution. The proportion of chromosome abnormalities varied with the gestational age of the abortus and the type of tissue cultured but was not significantly different among the five racial groups represented in the study population. It was suggested that differences in the rate of chromosome abnormalities among cytogenetic studies of spontaneous abortions were the result of methodological differences in sample selection rather than real biological variation among study populations. The only factor found to be unequivocally associated with the aetiology of chromosome abnormalities in spontaneous abortions was increasing maternal age in trisomies. 相似文献

In order to determine whether or not IFN-γR is associated with regulatory mechanisms on human eosinophil function, we examined the expression of functional IFN-γR on human peripheral eosinophils. In this study, peripheral blood eosinophils were obtained from seven normal controls and 12 patients (bronchial asthma, n = 9, and hypereosinophilic syndrome (HES), n = 3), and the purity of eosinophils was 97.11 ± 2. 31%, n = 19. We first showed that anti-IFN-γR α-chain MoAb reacted with all tested eosinophils of both normal controls and patients by flow cytometry analysis. We also showed expression of mRNA for the α-chain of IFN-γR in all purified eosinophils of six individuals. Further, to characterize IFN-γR on eosinophils, we did binding experiments with 125I-IFN-γ on purified peripheral eosinophils. The linear Scatchard plot indicated a single type of high-affinity binding sites (dissociation constant (Kd) = 3.89–4.95 × 10−10 m, numbers of binding sites = 183–233/cell, n = 3). To determine whether IFN-γR on eosinophils is functional, we examined surface eosinophilic cationic protein (ECP) and CD69 induction after IFN-γR ligation with recombinant human IFN-γ (rhIFN-γ) on eosinophils by flow cytometry. rhIFN-γ stimulation significantly induced both ECP and CD69 expression on the 2–18 h-cultured eosinophils in a dose-dependent manner. Further, the effects of rhIFN-γ stimulation were significantly blocked by both a neutralizing anti-IFN-γ MoAb and a blocking anti-IFN-γR MoAb. These results suggest that human peripheral eosinophils express functional IFN-γR. 相似文献

The reasons for morphological changes of urinary red blood cells (RBC) in patients with glomerulonephritis are still controversial. In order to evaluate the importance of mechanical damage by the glomerular basement membrane (GBM), we examined urinary RBC taken from the patients with two different diseases which have characteristic GBM changes. Urinary RBC taken from 20 patients with Alport syndrome and nine with thin GBM disease were examined using a scanning electron microscope. Nineteen out of the 20 patients (95.0%) with Alport syndrome showed ‘glomerular type’, while five of the nine patients (55.6%) with thin GBM disease showed ‘glomerular type’. These results suggest that more complicated GBM abnormalities cause more severe RBC distortion. Therefore, we conclude that mechanical damage by the GBM may be the major factor in dysmorphism of urinary RBC. 相似文献

The effects of a newly synthesized quinolinone derivative, 7-{4-(4-(2,3-dichlorophenyl)-1-piperazinyl) butoxy}-3,4-dihydro-2-(1H)-quinolinone (OPC-14597), a novel antipsychotic drug, on electrically evoked dopamine release in rat striatal slices were investigated. OPC-14597 (0.1–10 μm) had no effect on the dopamine release evoked in the striatal slices. The decrease induced by quinpirole, a dopamine receptor agonist, in evoked dopamine release was attenuated by supervision with OPC-14597 (1 and 10 μm) which by itself had no effect on evoked dopamine release. The increase induced by (–)-sulpiride, a dopamine receptor antagonist, in evoked dopamine release was, moreover, also attenuated by 1 and 10 μm OPC-14597. These findings indicate that OPC-14597 antagonizes both dopamine agonist- and antagonist-induced changes in evoked dopamine release in striatal slices in rats. 相似文献

Flow cytometry (FC) is widely utilized in the diagnosis of lymphoma and the light chain ratio (LCR) is especially useful in the diagnosis of B‐cell malignancy. In this study we analysed, retrospectively, the predictive value of the LCR in the diagnosis of B‐cell lymphoma in 105 consecutive patients with persistent lymph node enlargement or extranodal masses who underwent biopsy. We used a receiver‐operating characteristic curve to establish a LCR threshold value of 2.0. The specificity, sensitivity, positive and negative predictive values were 92.3%, 73.1%, 90% and 77%, respectively. We concluded that determination of LCR is a useful adjunct to pathological diagnosis. 相似文献
