Pulmonary Hypertension in Patients With Severe Aortic Stenosis: Prognostic Impact After Transcatheter Aortic Valve Replacement: Pulmonary Hypertension in Patients Undergoing TAVR

Objectives

The authors investigated the development of pulmonary hypertension (PH), predictors of PH regression, and its prognostic impact on short, mid-, and long-term outcomes in patients undergoing transcatheter aortic valve replacement (TAVR) for severe aortic stenosis (AS).

力因素引起楔状缺损的研究进展

楔状缺损是一种常见的牙体硬组织非龋性疾病,刷牙、酸的作用、牙颈部结构及力作用是其常见的病因。近20年来,临床研究中根据该病的一些特殊表现,研究了力对楔状缺损形成的影响,本文就引起楔状缺损的力因素这个病因作一综述。

??Centric relation is a vital factor in the prosthodontics of full denture?? occlusion reconstruction?? checkup and treatment of occlusion dysfunction?? dental prosthodontics?? orthodontic treatment?? temporomandibular joint disorder and so on. Traditional methods to construct the centric relation mainly include gothic arch tracing??swallowing and occluding method??retroflex licking method ??functional reflex method??Chin-point guidance method??bimanual manipulation method??recording of mandibular movement?? Myo-monitor?? and so on. All of them are quite flexible and difficult to repeat the same position??which is not suitable for the beginners. Patients' active cooperation is also necessary. This review summarized traditional methods to construct the centric relation?? and introduced a new tool named Leaf Gauge which can be used to record the accurate centric relation. It does not need sufficient clinical experience and is easy to grasp.     

超声引导下竖脊肌平面阻滞和椎旁神经阻滞对VATS患者术后镇痛和恢复影响的比较

目的比较超声引导下竖脊肌平面阻滞和椎旁神经阻滞对VATS患者术后镇痛和恢复的影响。方法纳入拟择期进行VATS的患者80例,年龄18～80岁,ASA分级Ⅰ～Ⅱ级,体重≥40kg。患者被随机分配到竖脊肌平面阻滞组（ESPB组,n=40）和椎旁神经阻滞组（PVB组,n=40）,分别使用30、20mL 0.375%罗哌卡因进行阻滞。主要观察指标是术后第1天的40项恢复量表（QoR-40）评分,次要观察指标是术后1、6和12h的NRS疼痛评分。同时记录患者术中舒芬太尼的使用量、术后并发症的发生情况以及患者满意度。结果ESPB组和PVB组术后第1天的QoR-40量表评分（P=0.829）及术后1、6和12h的NRS疼痛评分差异均无统计学意义（P=0.0655、P=0.423、P=0.426）。两组患者术中舒芬太尼的使用量和术后并发症的发生情况也均无明显差异。ESPB组的患者满意度更高（P=0.0033）。结论超声引导下竖脊肌平面阻滞在加快VATS患者康复和术后镇痛方面与椎旁神经阻滞效果相当。竖脊肌平面阻滞可以作为一种新型的区域神经阻滞技术广泛应用于临床。     

Fabrication of maxillary single complete denture in a patient with deranged mandibular occlusal plane: A case report

Construction of a single complete denture (SCD) is a challenging clinical situation especially when the opposing natural dentition is not in a normal plane of occlusion. Mal-aligned, tilted or supra-erupted teeth in the opposing arch are some of the problems that should be corrected to achieve a balanced occlusion in patients who require SCD. Achieving harmonious occlusal plane is a primary objective of any restorative procedure to facilitate natural mandibular movements and ease of mastication. Establishment of normal occlusal plane in opposite arch is pre-requisite to maintain the stability of the SCD. This clinical report describes restoration of mandibular teeth (with severe attrition and deranged occlusion) by establishing normal plane of occlusion with the help of custom made occlusal plane template (OPT) followed by construction of a complete denture in maxillary arch.     

开张式双殆垫与塑料殆垫治疗磨牙症的对比研究

目的：比较开张式双胎垫在治疗磨牙症中与塑料殆垫的临床疗效。方法：分别用自制的开张式双殆垫与塑料殆垫对48例磨牙症患者进行治疗,随访9个月。统计治疗结束1个月和9个月时的停止磨牙病例和平均减少的磨牙时间。结果：戴用1个月停止磨牙病例数比为6：12,戴用9个月时停止磨牙病例数比为10：21。其差异具有显著性（P〈0．01）。结论：开张式双殆垫治疗磨牙症优于塑料殆垫。
