Intravenous cidofovir treatment for recalcitrant warts in the setting of a patient with myelodysplastic syndrome

Cidofovir is an acyclic nucleoside phosphonate with broad-spectrum activity against DNA viruses, including human papilloma virus (HPV). However, data on the efficacy of cidofovir in an immunosuppressive setting remain contradictory. We report for the first time on the promotion of the healing of recalcitrant warts in a patient with myelodysplastic syndrome with intravenous cidofovir treatment.

十二烷氮酮氟尿嘧啶凝胶治疗疣及银屑病150例

443例(男225例,女218例;年龄36±14a)皮肤病患者,其中150例(扁平疣52例、寻常疣55例、银屑病43例)外用含1.8％十二烷氮(艹卓)酮的1％氟尿嘧啶(5-FU)凝胶作为治疗组,148例外用1％5-FU凝胶及145例外用2.5％5-FU霜作为2个对照组。经双盲对照临床试验,结果表明含1.8％十二烷氮(艹卓)酮的1％5-FU凝胶的疗效明显优于2个对照组(P<0.01及P<0.005)。证明氮(艹卓)酮对5-FU确有渗透促进作用。     

Successful treatment of periungual warts using photodynamic therapy: a pilot study

AIM: The aim of this pilot study was an investigation on photodynamic therapy (PDT) whether it is a good alternative for treating periungual and subungual warts of the hands. STUDY DESIGN: Twenty patients (mean age: 30.5 years) with a total of 40 periungual and subungual warts were treated with PDT. A photosensitizer, 20%delta-aminolevulinic acid was applied on the warts. After a mean incubation time of 4.6 h (SD: 1.2), the warts were irradiated with the VersaLight for 5-30 min (15.2 +/- 4.3 min). RESULTS: After a mean of 4.5 treatments a mean clearance of 100% was achieved in 90% of the patients. One patient (5%) showed a clearance of 50% and another showed no improvement. The subungual or periungual location of the wart had no influence on the number of treatments or end result (P > 0.05). There were two recurrences during the mean follow-up period of 5.9 months (SD: 7.6). Besides mainly pain and hyperpigmentation, most treatments had no side-effects. CONCLUSION: PDT can offer a good alternative for treating periungual warts of the hands. Larger studies are indicated.     

银黄洗剂治疗下肢血栓性浅静脉炎的临床疗效观察

目的:观察银黄洗剂治疗下肢血栓性浅静脉炎的临床疗效。方法:将62例诊断为下肢血栓性浅静脉炎的患者随机分为对照组和观察组,各31例。对照组在常规治疗的基础上应用硫酸镁湿敷,观察组在常规治疗的基础上应用银黄洗剂湿敷,疗程均为10 d。比较两组患者临床症状评分(皮肤颜色、患肢肿胀、硬索结节及疼痛的评分)、相关实验室指标(超敏C反应蛋白及纤维蛋白原)的变化情况以及总有效率。结果:观察组总有效率90.32%,高于对照组的64.52%(P<0.05)。与治疗前比较,两组症状体征评分明显改善,超敏C反应蛋白及纤维蛋白原明显降低(P<0.05)。观察组在改善症状体征及降低炎性反应方面较对照组更明显(P<0.05),两组治疗后纤维蛋白原数值比较,差异无统计学意义(P>0.05)。结论:银黄洗剂治疗下肢血栓性浅静脉炎,可有效改善患者临床症状及降低炎性反应,明显提高临床疗效。     

薄层扫描法测定洁阴洗液中苦参碱的含量

目的：采用双波长薄层扫法测定洁阴洗液中苦参碱的含量。方法：用反射式锯齿扫描法测定,测定波长λｓ＝５２０ｎｍ,参比波长λＲ＝ｎｍ;展开剂为：氯仿－甲醇－氨水（３０：１：０．５）,显色剂为稀碘化铋钾试液。结果：点样量在０．６１３￣３．０６４μｇ范围内呈良好的线性关系,平均回收率为９９．５４％,ＲＳＤ为１．３５％（ｎ＝６）。结论：该法分离效果好,简便,快速,结果准确,适用于该制剂的质量控制。
