Cardiac myxoma with glandular component: case report

Cardiac myxoma has varying clinical presentation, uncertain histogenesis and debatable immunohis- tochemical profile. Glandular epithelial differentiation is a rare phenomenon, but glandular elements are known to be present in cardiac myxoma as an intrinsic component of the tumor. We present a case of cardiac myxoma having focal glandular differentiation, with special reference to the morphologic features and immunohistochemical profiles.     

Combined transbronchial needle aspiration and positron emission tomography for mediastinal staging of NSCLC.

There are no data available combining transbronchial needle aspiration (TBNA) of mediastinal lymph nodes and positron emission tomography (PET) in the staging of nonsmall cell lung cancer (NSCLC). The aim of the current study was to determine if these two methods can enhance the negative predictive value of the individual modality alone, for a specific lymph node station, and if this integrated approach can reduce the number of mediastinoscopies. A total of 113 patients with enlarged mediastinal lymph nodes (> or = 1 cm), who underwent both TBNA and PET scanning, were included. In 51 patients, histopathology, confirmed by surgical lymph node dissection, was compared with PET results and TBNA. Sensitivity, specificity, positive predictive value, negative predictive value and accuracy to detect malignant lymphadenopathy was 68 (13/19), 89 (119/134), 46 (13/28), 95 (119/125) and 86% (132/152) for PET, respectively; 54% (6/11), 100 (53/53), 100 (6/6), 91 (53/58) and 92% (59/64), respectively for TBNA; and 100 (11/11), 94 (50/53), 79 (11/14), 100 (50/50) and 95 (61/64) for combined TBNA and PET, respectively. Combination of transbronchial needle aspiration and positron emission tomography has the potential to allow adequate mediastinal staging of nonsmall cell lung cancer with enlarged lymph nodes in most patients without the need for mediastinoscopy.     

微波对医院用纸张类物品的消毒效果

目的了解微波对纸张的消毒效果,减少院内感染。方法采用乙型肝炎表面抗原(HBsAg)阳性血清,沙门菌、大肠埃希菌、黄曲霉菌、金黄色葡萄球菌、巨大芽孢杆菌制成模拟标本,分时分层进行微波处理。结果在75℃消毒10 min的情况下,对纸张类物品的表面及其他层微生物均有杀灭作用。结论待消毒纸张用牛皮纸包好,放在微波专用塑料蒸煲内,高火或中高火消毒2~3 min,可达消毒目的。     

Prevalence and risk behaviors of Chinese men who seek same-sex partners via the internet in Hong Kong.

To examine the prevalence of Internet sex networking among men who have sex with men (MSM) in Hong Kong and risk behaviors associated with the behavior, a telephone survey of 15,230 Hong Kong Chinese men aged 18-60 was conducted. Of the 283 active MSM (having engaged in some MSM behaviors in the last 6 months) identified, 17.7% had networked for MSM partners via the Internet in the last 6 months. Younger age (odds ratio [OR] for age < or = 25 vs. age >25 = 4.67, 95% confidence interval [CI] = 2.35-9.28) and being an anal-sex MSM (OR = 4.72, 95% CI=2.36-9.44) were independent predictors of Internet sex networking. Being an Internet sex networker was associated with some risk behaviors such as having contracted a sexually transmitted disease (adjusted OR = 4.79, 95% CI = 1.34-17.11), having had > or = 3 MSM partners (adjusted OR = 4.74, 95% CI = 2.20-10.23), and having engaged in anal sex (adjusted OR = 3.95, 95% CI = 1.89-8.23). HIV prevention programs for MSM should thereby include Internet-based interventions.     

喹诺酮类药物致急性肾衰临床分析

目的分析喹诺酮类药物对肾脏功能的影响。方法对近14年来应用喹诺酮类药物引起急性肾衰（ARF）29例进行分析。结果应用5d以内者ARF的发生率为10．3％，随着应用时间延长，发生率逐渐增高；55岁以下ARF发生率为2．0％，随年龄增大，发生率逐渐增高；非少尿型ARF预后较好，少尿型预后较差。结论年龄越大，疗程越长，ARF发生率越高。
