微创治疗方法在输尿管上段结石中应用进展

输尿管上段结石为临床中常见泌尿系结石类型之一,如不能及时诊治,可引起重度积水、泌尿系感染,甚至脓毒血症,对患者肾功能、健康造成严重影响。随着微创治疗技术在泌尿系结石中应用,微创治疗方法能降低对患者造成治疗性创伤,降低相关并发症发生率,促进患者康复,了解临床中微创治疗输尿管上段结石方法,对临床中合理治疗输尿管上段结石有重要价值。     

577 nm激光光凝联合玻璃体内注射康柏西普治疗糖尿病性黄斑水肿的效果观察

目的　探讨577 nm激光光凝联合玻璃体内注射康柏西普治疗糖尿病性黄斑水肿的效果。方法　选取2016年1月至2017年3月在我院治疗的糖尿病性黄斑水肿患者81例81眼，根据患者最终选取的治疗方案分为观察组43例43眼和对照组38例38眼，观察组给予577 nm激光光凝联合玻璃体内注射康柏西普治疗，对照组仅给予577 nm激光光凝，观察两组治疗前后最佳矫正视力（best corrected visual acuity，BCVA）和黄斑中心凹厚度（central fovea of macula thickness，CMT），分析观察组BCVA和CMT变化值与初始因素的相关性。结果　随治疗时间延长，观察组和对照组BCVA、CMT相应改善（均为P＜0.05）；观察组治疗后1个月、3个月和6个月BCVA分别为0.37±0.09、0.44±0.10和0.52±0.13，均明显高于对照组（均为P＜0.05）；观察组治疗后1个月、3个月和6个月CMT分别为（351.03±41.43）μm、（270.32±40.03）μm和（220.01±32.91）μm，均明显低于对照组（均为P＜0.05）；BCVA变化值与糖尿病性黄斑水肿病程、治疗前BCVA呈负相关（r=-0.422、-0.410，均为P＜0.05）；CMT变化值与糖尿病性黄斑水肿病程、治疗前CMT呈负相关（r=-0.430、-0.415，均为P＜0.05）。结论　577 nm激光光凝联合玻璃体内注射康柏西普治疗糖尿病性黄斑水肿效果较好，其效果与患者基线BCVA、糖尿病性黄斑水肿病程有一定相关性。     

Hailey–Hailey disease improved by fractional CO2 laser

Hailey–Hailey disease (HHD), also known as benign familial pemphigus, is an autosomal dominant skin condition that affects the adhesion of epidermal keratinocytes. Although the initial manifestation of flaccid vesicles on erythematous or normal skin in flexure sites frequently goes unnoticed, large, macerated, exudative plaques of superficial erosions with crusting are observed at the time of diagnosis. There is no specific treatment for HHD, and most cases are symptomatically supported. However, infrared laser ablation has been somewhat helpful. We present a case successfully treated with fractional CO₂ laser showing a long-term favourable outcome and no adverse effects. Thus, this modality could be an alternative to full ablation for this condition.

Advance in Functional Restoration of Injured Nerve with Low Level Laser and its Utilization in the Dental and Maxillofacial Region

The inferior alveolar nerve and facial nerve are the two most important nerves in the dental and maxillofacial region. The injury to them is one of the major postoperative complications after alveolar surgery and orthognathic surgery. However, recovering the nerve function after injury takes a long time and the recovery effect tends to be unsatisfactory. In recent years, an intensively investigated technique, low level laser which has been applying in assisting the recovery of nerve function, has been gradually proved to be effective in clinically treating postoperative nerve injury. In this article we review in terms of the mechanisms involved in low level laser-assisted functional restoration of nerve injury and its clinical application in the recovery of nerve function in the dental and maxillofacial area as well.     

Ospemifene plus fractional CO2 laser: a powerful strategy to treat postmenopausal vulvar pain

Abstract

This study is a single-center, retrospective analysis of postmenopausal women presenting with dyspareunia and vulvar pain, aiming to evaluate relative effectiveness of vestibular CO₂ laser therapy as a treatment. Three monthly sessions of laser were performed to each patient and thereafter a three-months follow-up was stablished. A total number of 72 patients undergoing vestibular laser treatment were recruited from patient files in the period between 2016 and 2018. Among these, 39 women also received a concomitant treatment with ospemifene (60?mg/day) during the study period. There was a statistically significant reduction of all the symptoms in both groups up to the three month follow-up. Regarding dryness and dyspareunia, the relief tent to be more prominent in the ospemifene?+?laser group at all follow-ups and remained statistically significant at three-month follow-up. Specifically, vestibular dryness was significantly lower in the ospemifene?+?laser group compared with the laser treatment group (?87% vs???34%, respectively), and the vestibular health score started declining faster in the ospemifene?+?laser group. Although, additional research is needed to understand the mechanism of action, our data shows that a combination regimen of laser and ospemifene may improve clinical effectiveness for long-term treatment of symptoms associated with the under-recognized genitourinary syndrome of menopause.
