Complications Related to Dapsone Use for Pneumocystis Jirovecii Pneumonia Prophylaxis in Solid Organ Transplant Recipients

Dapsone, used for prevention of Pneumocystis jirovecii infections, has been reported to cause hemolytic anemia and methemoglobinemia; its tolerability in solid organ transplant recipients is not well described. We investigated dapsone-related adverse events in patients undergoing solid organ transplantation from 1999 to 2004. Transplant providers identified patients for the investigators who then reviewed the patients' hospital and outpatient records. Sixteen solid organ transplant recipients fit case definitions for dapsone-related hemolytic anemia (n = 11) or methemoglobinemia (n = 5). Median time from event to dapsone discontinuation was 15 days; all patients improved after drug discontinuation. G6PD enzyme activity was normal in all patients whose test results were available. Dapsone may be associated with hemolytic anemia or methemoglobinemia, even with normal G6PD levels. These events are often not promptly recognized, and drug discontinuation is delayed. Dapsone-related hemolytic anemia or methemoglobinemia should be considered in solid organ transplant recipients with unexplained anemia or hypoxia.     

Excessive daytime somnolence in Japanese patients with Parkinson''s disease

To investigate the prevalence and severity of excessive daytime somnolence (EDS) in Japanese patients with Parkinson's disease (PD) and to examine the main cause of EDS. Fifty-three Japanese patients with PD (PDs: 32 females and 21 males) and 17 controls (10 females and seven males) were evaluated using the Epworth Sleepiness Scale (ESS). The severity of the disease was evaluated by Unified Parkinson's disease Rating Scale (UPDRS), and information about quality and quantity of medications was collected. The correlations amongst EDS and age, severity of PD, duration of illness and medications were analyzed. The mean ESS score was significantly higher in advanced PDs than in controls, and correlated with the UPDRS score (r(s) = 0.743, P < 0.0001). Age, duration of illness and the dose of levodopa weakly correlated with ESS score. The intake of dopamine agonists did not affect the severity of EDS. The mean ESS score in PDs was lower than that reported in PD in European and American studies. EDS in Japanese patients with PD was milder compared with Caucasian patients, which might be due to the lower doses of the medications used in Japan. The results suggest that EDS in PD is mainly because of neuropathological changes of the disease itself.     

Critical review of treatment trials in hypertension

Summary: Despite numerous deficiencies in some antihypertensive drug treatment trials, and some questionable selections of studies for inclusion in several meta-analyses, undoubtedly such trials have shown treatment benefits from reducing hypertension. Complications that can be corrected or prevented include malignant hypertension, hypertensive heart failure, stroke and coronary artery morbidity. the all-cause mortality has been lowered in several trials. the benefits have been seen in subjects aged over 60 years, in women and men, and in patients with isolated systolic hypertension. the benefits have been achieved using a wide range of drugs, not only with beta-blockers or diuretics. Non-pharmacological means of lowering blood pressure have not been evaluated in relation to morbidity.     

急性颅脑损伤患者脑脊液中兴奋性和抑制性氨基酸含量改变及其临床意义

采用氨基酸自动分析仪检测了１８例急性颅脑损伤患者脑脊液中谷氨酸、天门冬氨酸、牛磺酸、甘氨酸、丙氨酸、γ－氨基丁酸、脯氨酸含量的动态变化。结果发现，伤情越重、预后越差的患者，脑脊液中牛磺酸、γ－氨基丁酸、丙氨酸含量伤后早期升高越明显，恢复至正常的时间也越长；其中２例早期死于急性弥漫性脑肿胀、脑水肿的患者，伤后当天脑脊液中牛磺酸含量分别为９２．６和５１．５μｍｏｌ／Ｌ，是对照值的９．６倍和５．４倍，γ－氨基丁酸含量分别为１１９．８和２４６．２μｍｏｌ／Ｌ，是对照值的２．７倍和５．５倍。表明伤后脑脊液中牛磺酸、γ－氨基丁酸和丙氨酸含量的动态变化可初步反映颅脑损伤的严重程度及颅脑损伤患者的脑功能恢复状况，并可能与急性脑水肿、脑肿胀的病理生理过程有关。     

克林霉素在老年患者呼吸道感染中的应用

目的:探讨克林霉素在老年呼吸道感染中的应用价值.方法:38例老年呼吸道感染惠者随机分为治疗组(克林霉素)和对照组(青霉素 丁胺卡那霉素),观察临床疗效.结果:治疗组在退热时间和治疗时间上均短于对照组,差异具有显著性意义,而副反应少而轻微.结论:克林霉素治疗老年呼吸道感染安全有效.     

老年病人睡眠状况及护理干预研究进展

功能性矫治器在正畸矫治中运用的伦理思考

功能性矫治器是正畸临床中常用的一种矫治器，作者从口腔正畸学理论基础出发，探讨了功能性矫治器在正畸矫治作用中存在的伦理道德问题，主要有（1）不能正确的诊断、制定周密的矫治计划。（2）操作不规范、不细致、缺乏敬业精神。（3）态度简单，粗曝，缺乏与患者良好的交流。并提出解决方法（1）刻苦学习专业知识，不断提高诊疗水平及个人修养。（2）建立高度的道德责任感，以严谨的作风，规范的操作为病人服务。（3）尊重、善待青少年，建立良好的医患关系。     

肺部疾病中痰巨噬细胞对结核菌素试验反应的临床研究

目的:测定肺结核、肺肿瘤及非特异性炎症患者注射结核菌素前后痰巨噬细胞的不同数量变化,由此提供一种新的鉴别诊断方法。方法:皮内注射结核菌素、收集注射前、后痰液,测定痰巨噬细胞在不同时间的数量变化。结果:肺结核病人在结核菌素试验后痰巨噬细胞明显增加,肺部肿瘤及非特异性炎症则无显著性变化。结论:肺部患者测定结核菌素前后痰巨噬细胞变化,可作为菌阴肺结核与肺部肿瘤及非特异性炎症鉴别诊断依据之一。     

老年肝外胆管梗阻85例治疗分析

目的：探讨老年性肝外胆管梗阻的治疗。方法：85例老年胆管梗阻中良性疾病引起的梗阻为59例，主要是由于胆管结石嵌顿MIRRIZI‘S综合征；恶性肿瘤引起的梗阻为26例，主要为壶腹部周围癌，肝门区肿瘤等。手术分别采取胆囊切除术、胆总管切开取石＋T管引流术、胰十二指肠切除术、腹部探查＋内外引流术以及ERCP下行置管内支撑术后引流和ENBD等。结果：良性疾病引起的梗阻中仅1例术后死于ARDS，恶性肿瘤 引起的梗阻者中有11例术后死于肝肾综合征、ARDS和DIC等。结论；手术仍是老年肝外胆管梗阻的首选方法。老年患者合并其它脏器病变，病情较重者如先行胆管引流，能有效降低病死率及延长生命。
