输尿管部分切除术治疗原发性输尿管癌的长期随访分析

目的:探讨保留肾脏的输尿管部分切除术治疗原发性输尿管癌的长期疗效。方法:回顾性分析1999年3月~2013年2月行保留肾脏的输尿管部分切除术的31例输尿管癌患者临床资料:12例患者行输尿管膀胱再植术,19例行输尿管端端吻合术。随访14~171个月,观察术后尿路肿瘤复发率、患者总体生存率、肿瘤分期及病理分级方面分层生存率等情况。结果:术后尿路肿瘤复发率为19.35%(6/31);总体5年及10年生存率分别为77.41%、58.64%;低肿瘤分期组5年及10年生存率均为86.67%,高肿瘤分期组5年及10年生存率分别为74.93%和54.29%;低病理分级组5年及10年生存率均为76.00%,高病理分级组5年及10年生存率分别为78.26%和48.83%。结论:在严密随访下,输尿管部分切除术可以有效治疗低分期、低分级输尿管癌。     

ADAM33 polymorphisms and susceptibility to allergic rhinitis: a meta-analysis

European Archives of Oto-Rhino-Laryngology - Several polymorphisms in a disintegrin and metalloproteinase 33 (ADAM33) have been implicated in susceptibility to allergic rhinitis (AR), but the...     

In Vivo Kinematics of Functional Ankle Instability Patients and Lateral Ankle Sprain Copers During Stair Descent

Patients with mechanic ankle instability experience increased tibiotalar and subtalar joint laxity. However, in vivo joint kinematics in functional ankle instability (FAI) patients and lateral ankle sprain (LAS) copers, especially during dynamic activities, are poorly understood. Ten FAI patients, 10 LAS copers, and 10 healthy controls were included in this study. A dual fluoroscopic imaging system was used to analyze the tibiotalar and subtalar joint kinematics during stair descent. Five key poses of stair descent were analyzed. Kinematic data from six degrees of freedom were calculated utilizing a solid modeling software. The range of motion and joint positions in each degree of freedom were compared among the three groups. The tibiotalar joints of FAI patients and LAS copers were significantly more inverted than those of healthy controls during the foot strike (p = 0.016, = 0.264). The subtalar joints of FAI patients were significantly more anteriorly translated (pose 2, p = 0.003, = 0.352; pose 3, p < 0.001, = 0.454; pose 4, p = 0.004, = 0.334), inverted (pose 4, p = 0.027, = 0.234; pose 5,p = 0.034, = 0.221), and externally rotated (pose 4, p = 0.037, = 0.217; pose 5; p = 0.004, = 0.331) than those of healthy controls during the mid‐stance and the heel off. The FAI patients showed excessive tibiotalar inversion and subtalar joint hypermobility during stair descent. Meanwhile, the LAS copers maintained subtalar joint stability, and only showed excessive tibiotalar inversion in foot strike. These data provide insight into the mechanisms behind the development of FAI after initial LAS. © 2019 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.

Hypertension is a risk factor for adverse outcomes in patients with coronavirus disease 2019: a cohort study

Abstract

Background

Comorbidities are commonly seen in patients with coronavirus disease 2019 (COVID-19), but the clinical implication is not yet well-delineated. We aim to characterize the prevalence and clinical implications of comorbidities in patients with COVID-19.
