简介:AbstractIntroduction:Papular scarring of the nose and chin due to acne is an under-reported, under-recognized, and under-treated condition. Ablative carbon dioxide laser therapy (10,600 nm, continuous mode, energy of 15W) under local anesthesia is one of the choice. Here, we report series of patients with papular acne scars successfully treated with ablative carbon dioxide laser.Cases presentation:Five patients with papular scars of the nose and chin due to acne were treated at an outpatient dermatology clinic. All had type V skin according to the Fitzpatrick skin classification. Ablative carbon dioxide laser therapy (10,600 nm, continuous mode, energy of 15 W) was performed under topical anesthesia. The patients were re-examined at 2- to 3-week intervals, and laser treatment was repeated as needed.Discussion:All of the five patients showed encouraging results. Good cosmetic results were achieved in all patients. The drawbacks of treatment were mild to moderate pain during the procedure and the need for post-treatment skin care.Conclusion:Ablative carbon dioxide laser therapy can potentially be used as a safe and effective treatment for papular scars of the nose and chin due to acne.
简介:摘要:目的 对直肠癌患者应用NOSE手术的效果进行研究。方法 选择本院在2018年5月至2021年5月期间收治的50例直肠癌患者,随机分成人数相等的两组,记为对照组和研究组,各25例。对照组行腹腔镜下结直肠癌根治术,研究组行NOSE结直肠癌根治术,对比两组患者各项围术期指标及并发症发生率。结果 研究组术中出血量、手术时长、排气恢复时间和排便恢复时间等均低于对照组(P<0.05);研究组并发症发生率为8.00%,低于对照组的20.00%,组间对比无显著差异(P>0.05)。结论 NOSE技术针对直肠癌患者效果明显,可有效加快患者康复进程,降低不良反应发生率,值得作为主要术式广泛推广。
简介:AbstractObjective:To compare and correlate the efficacy of the NOSE score & the VAS score in determining the symptomatic benefit in patients undergoing septoplasty.Materials and methods:Eighty patients with deviated nasal septum undergoing septoplasty were included in the study. NOSE score & VAS score (out of 100) was documented before and after surgery. Results were correlated and compared statistically.Results:In the NOSE score, the most bothersome symptom was trouble breathing through the nose (85.83); followed by Nasal obstruction or blockage (82.50). Wilcoxon test showed significant improvement with NOSE score and VAS score in all patients at 1 month and 3 months. Spearman’s coefficient showed a positive correlation between the two, though the score improvement and patient satisfaction rate was significantly high with NOSE score.Conclusions:NOSE score and the VAS score both provide effective framework for evaluating treatment responses after septoplasty. However, the NOSE score showed higher improvement and better patient satisfaction rate when used to measure of nasal obstruction as compared to the VAS score.
