Voiding patterns in men and women with lower urinary tract symptoms combined with nocturia

AIM: We evaluated differences between men and women with lower urinary tract symptoms (LUTS) combined with nocturia. METHODS: A total of 71 age-matched female-male pairs (median 58, range 20-81 years) who had moderate to severe LUTS and nocturia of more than once per night were enrolled in this study. RESULTS: In the younger group (<50 years), the International Prostate Symptom Score (I-PSS) results of the sexes were not significantly different. However, although total I-PSS results in the elderly group (> or =50 years) were not significantly different, quality of life index scores for women were higher (P = 0.002). On frequency-volume (FV) charts, mean total daytime voided volume (DVV) was significantly higher in younger men than in younger women (P = 0.017), but the mean nocturnal polyuria index (NPi) for women was higher than that for men (P = 0.047). However, maximum DVV (P = 0.009), mean DVV (P < 0.0001), total DVV (P < 0.0001), and mean nocturnal urine volume (P = 0.009) were significantly higher in elderly men than in elderly women. However, numbers of daytime voids were not different. CONCLUSION: Elderly women with LUTS have lower functional bladder capacities than elderly men, as suggested by their smaller mean voided volumes. However, no significant differences were observed between numbers of daytime voids, which was probably due to the smaller total daytime voided volumes of elderly women. In addition, although NPi for younger women and nocturnal urine volume for elderly men was higher, no other differences were observed in terms of other night-time parameters.     

外引流术后的白内障超声乳化手术

目的：探讨抗青光眼餐引流术后的白内障患眼进行超声乳化吸除术的手术入路，操作方式及临床效果。方法：避开功能性滤过泡，选择角巩膜隧道切口或透明角膜切口，瞳孔麻痹性散大时，做一个完美的直径约5mm的连续环形撕囊以补偿之；恰当处理虹膜后粘连后，在病理性小瞳孔下完成超声乳化手术；眼压失控者行青光眼白内障人工晶体植入三联术。结果：无后囊破裂，人工晶体全部囊袋内植入，术后1周视力≥0．5者20只眼（64．5％），0．1－0．4者8只眼（25．8％），＜0．1者3只眼（9．7％）。随访1－16个月，眼压均在20.55mmHg以下。结论：体外流术后的白内障患眼，超声乳化手术因其切口小，并发症少，不破坏功能性滤过泡，不损伤瞳孔，是目前各种手术方法中的最佳选择。     

Additive effect of TRAIL and p53 gene transfer on apoptosis of human lung cancer cell lines

TRAIL is a cytokine that can induce tumor-specific apoptosis through its specific death receptors (DR4 and DR5) and p53 has been proven to increase the expression of death receptors. To examine their interaction in tumor suppression, p53 and TRAIL genes were inserted in recombinant adenovirus vectors and transferred simultaneously into non-small cell lung cancer cell lines (NCI-H157, NCI-H358, NCI-H460 and A549). Western blot assay demonstrated production of TRAIL protein in NCI-H157 and A549 cell lines. Increased expressions of DR4 and DR5 of NCI-H157 and DR4 of A549 after p53 overexpression were confirmed by flow cytometry. p53 or TRAIL gene transfer increased sub-G1 fraction in cell cycle analysis and inhibited the tumor growth dose-dependently and the degree was potentiated by co-transfer. But isobologram analysis indicated an additive effect. Together, these data indicate that p53 and TRAIL interact additively on tumor apoptosis despite theoretical synergism.     

Patterns of dysphoria in a Puerto Rican urban community.

This study was undertaken to explore the prevalence of perceived dysphoria in a poor, urban, predominantly Puerto Rican community. A cross-sectional sample of 704 adult respondents were asked a single validated question, with a five-item Likert scale response, about their level of perceived dysphoria. Chi-squared analysis and Spearman''s correlation coefficients were used to assess the association of level of dysphoria with social characteristics, barriers to health care, health status, and substance use. Linear regression modeling was used to control for confounding variables. Twenty percent of the respondents were dysphoric. Respondents with no health insurance or no source of health care were least likely to be dysphoric. Persons who perceived distance to the hospital and the doctor, and understanding language of the doctor and office staff as barriers to care were more likely to be dysphoric. Ethnicity was not correlated with level of perceived dysphoria; however, age, gender, and health status were found to be associated with level of dysphoria after controlling for other correlated variables. These results indicate that the psychological needs of communities need to be understood and interventions that are appropriate for the population need to be devised.
