退变性腰椎侧凸合并类风湿性关节炎患者侧凸程度的影响因素分析

目的 :分析退变性腰椎侧凸(degenerative lumbar scoliosis,DLS)合并类风湿性关节炎(rheumatoid arthritis,RA)患者的发病特征和侧凸程度的影响因素。方法 :单中心纳入2013年1月～2018年4月61例合并RA拟行腰椎手术的患者,分为患有DLS者27例(DLS组)和无脊柱畸形患者34例(NDLS组)。提取信息包括人口统计学信息[如性别、年龄和体重指数(body mass index,BMI)等]、RA相关信息[如Steinbrocker分级、是否服用改变病情抗风湿药(disease-modifying anti-rheumatic drugs,DMARDs)等]、手术相关信息和DLS信息[如Cobb角、顶椎旋转角度、冠状位顶椎偏移距离、髂嵴连线高度、骨质疏松、全膝关节置换(total knee arthroplasty,TKA)史和膝关节功能评分(knee society score,KSS)],Steinbrocker分级用来评价RA活动性,Cobb角反映腰椎侧凸程度,KSS用以评价膝关节功能。结果:患者平均RA病程为16.8±12.7年,Steinbrocker分级Ⅰ～Ⅲ级分别为14例、34例和13例。两组患者以女性为主,DLS组(男∶女=1∶26)和NDLS组(男∶女=8∶26)在性别上存在统计学差异(P=0.031),而在年龄、BMI上无统计学差异(P0.05);两组在Steinbrocker分级、服用DMARDs比例和骨质疏松患者比例上无统计学差异(P0.05)。两组共11例实施TKA手术,两组间TKA分布比较无统计学差异(P=0.153)。DLS组平均侧凸程度(Cobb角)为18.4°±9.0°(10.4°～39.2°),实施TKA患者其Cobb角(11.8°±1.5°)小于无TKA者(20.6°±9.5°)(P=0.001)。DLS组顶椎旋转角度为8.4°±6.8°,冠状位偏移距离为47.3±7.8mm,髂嵴连线均位于L4/5椎间隙。Cobb角与顶椎旋转角度、冠状位偏移距离和TKA存在相关性(P0.05),与其余参数均无显著相关性。针对DLS患者侧凸程度回归分析,显示既往行TKA为其影响因素(P=0.029),但TKA发生时间、TKA患者DLS病程与侧凸程度无明确相关性。行TKA患者KSS评分(88.7±5.3分)高于未行TKA者(80.4±10.0分)(P=0.034),KSS和Cobb角之间存在负相关性(r=-0.717,P0.001),以Cobb为因变量的两者之间的拟合曲线为Cobb角=70.38-0.64×KSS。结论:合并RA的DLS患者在中老年女性更易出现;在既往行TKA的RA患者中,DLS侧凸程度较小;KSS与DLS侧凸程度存在高度相关性。

普通外科医师如何识别和紧急救治肺动脉栓塞

肺动脉栓塞(PE)在普通外科病人中并不少见。普通外科医师有必要掌握诊断和治疗的基本知识,提高及时识别PE能力。在紧急抢救时,早期处理和快速启动会诊系统非常重要。发现病人存在PE的可疑临床表现和体征时,监测血D-二聚体,如果阳性启动Wells评分,当评分≥2分时,进行相关确诊检查。高度疑诊和确诊的高危PE的紧急救治需要区别对待,前者难度和风险更大,需要多学科团队的快速联合干预。     

Can the unnecessary operations for suspected thyroid nodules be avoided by the combined use of the strain ratio and elastography score?

IntroductionOnly 5%–15% of thyroid surgical specimens are reported as malignant. Most of the operations are performed due to suspicion of malignancy as a result of fine needle aspiration biopsy but invasiveness, non-diagnostic results and potential repeat biopsies are disadvantages of fine needle aspiration biopsy.ObjectiveThe aim of this study was to investigate the effectiveness of simultaneously using both the strain ratio and elasticity score in the differential diagnosis of thyroid nodules, as well as to assess the compatibility of these two methods.MethodsA total of 144 nodules were included in the study. The final histopathologic diagnosis was used as the reference standard. The area under the curve sensitivity, specificity, and cut-off values of the strain ratio and elasticity score were determined using receiver operating characteristic curve analysis. The compatibility and comparison of strain ratio and elasticity score were also performed.ResultsTwenty eight nodules (19.4%) were malignant. The strain ratio and elasticity score results were found to be significantly successful in predicting thyroid malignancy (p < 0.001 for both). Moreover, the area under the curve for the strain ratio and elasticity score were found to be 0.944 and 0.960, respectively. The diagnostic accuracy of the elasticity score was found to be superior to that of the strain ratio, but this difference was not statistically significant (p = 0.456). When the compatibility of the strain ratio and elasticity score was examined, the two evaluations were revealed to be statistically consistent with each other (Kappa = 0.767; p < 0.001). When the strain ratio and the elasticity score were used together, the specificity of capturing the correct diagnosis increased from 84.5% to 93.1%.ConclusionWhen the strain ratio an elasticity score were used together for the differential diagnosis of thyroid nodules, more accurate results were obtained. Thus, combining both methods may be a promising alternative to fine needle aspiration biopsy in order to prevent unnecessary surgical interventions for suspected thyroid nodules.     

Association between hemoglobin glycation index and subclinical myocardial injury in the general population free from cardiovascular disease

Background and aimsThe relationship between hemoglobin glycation index (HGI) and the diagnosis and prognosis of cardiovascular disease (CVD) has been verified by previous studies. However, it remains unknown whether HGI has a predictive effect on subclinical myocardial injury (SC–MI). The purpose of the present study was to explore the relationship between HGI and SC–MI in the general population free from CVD.Methods and resultsThe present study included 6009 participants free of CVD from the third National Health and Nutrition Examination Survey. Binary Logistic regression analysis was used to tested the association between HGI and SC–MI. As results, the HGI was significantly higher in participants with SC–MI compared with those without, and the HGI was positively correlated with SC–MI and other metabolic disorder parameters. Each 1-unit increase of HGI and glycated hemoglobin A1c (HbA1c) was independently associated with higher risk of SC–MI (P < 0.05), while fasting plasma glucose (FPG) was no longer a predictive indicator of SC–MI with the increase of confounding factors [OR (95% CI): 1.001 (0.999–1.003), P = 0.305]. And in the subgroup analysis, HGI, only in participants without diabetes, was independently associated with higher risk of SC–MI, while HbA1c and FPG had no independent predictive role in both diabetic and non-diabetic participants.ConclusionsHGI was a significant predictor of SC–MI in the general population free from CVD.     

Buried Bumper Syndrome: A common complication of levodopa intestinal infusion for Parkinson disease

BackgroundPercutaneous endoscopic gastrostomy (PEG) is required for Levodopa/Carbidopa Intestinal Gel (LCIG) delivery in patients with advanced Parkinson's disease (PD) as well as for enteral feeding in a variety of neurological disorders. Buried Bumper Syndrome (BBS) is a serious complication of PEG. The frequency of BBS in patients receiving LCIG treatment has never been reported.ObjectivesTo compare the frequency of BBS in patients on LCIG treatment or on enteral feeding over the past 12 years and identify possible risk factors.MethodsWe reviewed prospectively recorded data from 2009 to 2020 on two case-series: LCIG-treated PD patients and non-PD patients on enteral nutrition. We identified all BBS incidences. Patients’ characteristics, clinical manifestations, BBS management, possible risk factors and outcomes were analyzed.ResultsDuring the 12 years, 35 PD patients underwent PEG insertion for LCIG infusion, and 123 non-PD patients for nutritional support. There were eight cases of BBS in six PD patients (17.1%). Six of them were effectively managed without treatment discontinuation. Of the enteral feeding patients, only one developed BBS (0.8%) (p < 0.001). We identified inappropriate PEG site aftercare, weight gain, early onset PD, longer survival, treatment duration, dementia and PEG system design as potential risk factors for BBS development.ConclusionsBBS occurs more frequently in LCIG patients than in patients receiving enteral feeding. If detected early, it can be successfully managed, and serious sequalae or treatment discontinuation can be avoided. Regular endoscopic follow-up visits of LCIG-treated patients and increased awareness in patients and clinicians are recommended.
