夫西地酸乳膏联合阿达帕林凝胶治疗寻常痤疮的疗效

 目的 探讨夫西地酸乳膏联合阿达帕林凝胶治疗寻常痤疮的疗效。方法 选择武警黑龙江总队医院诊治的寻常痤疮患者110例,随机分为对照组和观察组,每组各55例。对照组单独应用阿达帕林凝胶治疗,观察组联合应用夫西地酸乳膏与阿达帕林凝胶,两组均持续治疗4周。比较两组治疗后皮损数量、不良反应、复发率等。结果 治疗4周后,与对照组相比,观察组炎性皮损、非炎性皮损个数明显减少,差异有统计学意义(P＜0.05),两组治疗后不良反应差异无统计学意义。治疗后6个月,观察组的复发率3.64%(2/55)低于对照组14.55%(8/55),差异有统计学意义(P＜0.05)。结论 夫西地酸乳膏联合阿达帕林凝胶治疗寻常痤疮,可明显改善皮损情况,安全性较高,复发率低。     

The use of isotretinoin for acne – an update on optimal dosing,surveillance, and adverse effects

ABSTRACT

Introduction

Acne is a chronic, inflammatory, and immune mediated disease of pilosebaceous unit, highly prevalent in adolescents. It involves face, trunk, and back; may leave scars and affect quality of life. Early, effective, and safe treatment is the key for disease resolution. Oral isotretinoin is the unique treatment for cure or prolonged remission for moderate and severe acne, preventing psychosocial impact and scars. It inhibits sebaceous glands activity and has anti-inflammatory and immunoregulatory properties.     

寻常痤疮发病机制相关信号通路的研究进展

寻常痤疮是一种毛囊皮脂腺单位的炎症疾病,在青少年中的发病率高达85%,发病机制与雄激素、皮脂分泌、嗜脂性微生物感染、免疫-炎症反应等密切相关。本文从炎症信号通路、皮脂分泌通路方面,综述与痤疮相关的信号转导通路。     

超分子水杨酸治疗痤疮的效果及对皮肤屏障的影响

目的:观察超分子水杨酸对于痤疮的疗效及皮肤屏障的影响。方法:采用随机对照实验。选取痤疮患者40例,随机分为实验组和对照组,每组20例。实验组:给予30%超分子水杨酸换肤治疗,1周1次并配合外用特护霜,共治疗4次;对照组:仅每日给予特护霜外用。疗程结束4周后随访观察。治疗前及随访时使用CK无创皮肤检测仪检测两组患者面部皮肤生理指标,计数面部皮损。使用VISIA皮肤分析仪拍照留存。结果:实验组总有效率90%,对照组总有效率15%,两组比较有显著性差异(P<0.05)。同治疗前相比,实验组治疗后经皮水分丢失量(TEWL)、红斑值、角质层含水量及p H值均有改善,差异均有统计学意义(P<0.05)。与对照组比较,实验组治疗后TEWL、角质层含水量及p H值均有改善,差异均有统计学意义(P<0.05)。两组患者均未出现色素沉着、瘢痕等不良反应。结论:超分子水杨酸治疗痤疮疗效确切,同时具有修复皮肤屏障的作用。     

超脉冲CO2点阵激光联合PRP治疗面部痤疮凹陷性瘢痕疗效分析

目的:探究超脉冲CO2点阵激光联合富血小板血浆(PRP)治疗面部痤疮凹陷性瘢痕的疗效。方法:72例面部痤疮凹陷性瘢痕患者,随机分为观察组(36例)和对照组(36例)。对照组采用超脉冲CO2点阵激光治疗,观察组采用超脉冲CO2点阵激光联合PRP治疗。比较两组患者的灰度差异、时间指标、瘢痕程度、疼痛、不良反应及视觉评估。结果:观察组的并发症发生率为11.11%,低于对照组的36.11%,差异具有统计学意义(P<0.05)。治疗后,两组患者的灰度差异率均减小,且观察组患者的灰度差异率显著低于对照组,差异具有统计学意义(P<0.05)。治疗后,观察组的炎性渗出时间、红肿时间、愈合时间、停工时间及瘢痕程度评分均低于对照组,差异均具有统计学意义(P<0.05);但疼痛度评分组间比较,差异无统计学意义(P>0.05)。结论:超脉冲CO2点阵激光联合PRP治疗面部痤疮凹陷性瘢痕效果较好,可有效降低瘢痕程度,减少治疗时间及并发症的发生,帮助患者迅速回归正常工作与生活,值得临床推广使用。     

Topical 2% ketoconazole cream monotherapy significantly improves adult female acne: A double‐blind,randomized placebo‐controlled trial

The emergence of bacterial resistance is a global crisis. Prolonged use of antibiotics especially in acne is one issue of concern among dermatologists. Ketoconazole (KTZ) cream, a topical antifungal with anti‐inflammatory and antiandrogenic actions, can decrease lipase activity of Cutibacterium acnes in vitro. We evaluated the efficacy and safety of KTZ cream in mild adult female acne (AFA) by conducting a randomized, double‐blind, placebo‐controlled trial using KTZ 2% and placebo cream twice daily for 10 weeks. We assessed the improvement of clinical severity, measured by AFA score graded by investigators and participants, and the change of acne count. Forty‐one participants enrolled in our study. The proportion of participants with acne improvement from baseline (42.9% vs 9.5%, P = 0.015) and the success rate (45.0% vs 14.3%, P = 0.043) in the KTZ group were significantly higher than that of the placebo group. The most common adverse events were dryness and itching. The percentage change of acne count decreased significantly compared with baseline but did not differ statistically between the two groups (P = 0.268). We concluded that the KTZ monotherapy showed a plausible effect in improving AFA with excellent safety profile. It should be considered as a viable option for mild AFA treatment.     

丹芩消郁合剂结合刺络拔罐法治疗肝郁湿热型痤疮35例

目的:观察丹芩消郁合剂结合刺络拔罐法治疗肝郁湿热型痤疮的临床疗效。方法:选择肝郁湿热型中度痤疮患者70例,随机分为治疗组和对照组,每组各35例。治疗组口服丹芩消郁合剂结合刺络拔罐治疗,对照组口服丹参酮胶囊治疗。观察两组患者的临床疗效,比较两组患者治疗前后中医证候积分变化情况。结果:治疗组有效率为94.29%,对照组有效率为88.57%,两组患者有效率比较,差异无统计学意义(P0.05);治疗组愈显率为74.29%,对照组愈显率为51.43%,两组患者愈显率比较,差异具有统计学意义(P0.05)。治疗后两组患者中医证候积分较治疗前显著降低,且治疗组低于对照组,差异具有统计学意义(P0.05)。结论:丹芩消郁合剂结合刺络拔罐法治疗肝郁湿热型痤疮,可有效改善患者的临床症状。
