Infections in primary total ankle replacement: Anterior approach versus lateral transfibular approach

Background

Total ankle replacement (TAR) represents an alternative to fusion for the treatment of end-stage ankle osteoarthritis. The aim of the present study was to retrospectively assess the frequency of infections between TARs with anterior and lateral transfibular approach at 12-months follow-up.

Treatment of oral manifestations of toxic epidermal necrolysis with low‐level laser therapy in a pediatric patient

Drug‐induced reactions are complications associated with high mortality and significant morbidity. Stevens–Johnson Syndrome (SJS) and toxic epidermal necrolysis (TEN) are examples of these conditions, which are characterized by skin and mucous lesions. Here, we report a case of a 9‐year‐old girl who presented with blisters associated with an extensive vesicular rash and multiple ulcerations on the lips and oral cavity. A drug‐induced hypersensitivity reaction to antibiotics was suspected, and a diagnosis of TEN was made. The patient was managed with withdrawal of the suspected causative agent, and the oral lesions were treated with low‐level laser therapy (LLLT) and oral hygiene. This case highlights that TEN requires interdisciplinary intervention with dental assistance and follow‐up to improve symptoms, nutrition, systemic condition, and quality of life.     

痛风患者的健康素养：一项关于东北地区中青年患者的质性研究

背景　痛风是一种代谢性疾病，可以并发肾、心脑血管等多器官疾病，目前痛风发病和预后的影响因素已经得到揭示，但鲜有通过质性研究方法全面评估痛风患者的疾病认知和健康素养状态。目的　探讨东北地区中青年痛风患者的健康素养，并了解痛风患者的一般感知能力及知识需求状况，为增强我国痛风患者的健康素养水平，改善其自身管理能力、提高痛风患者的生活质量提供理论依据。方法　招募2017年3月-2018年3月于大庆油田总医院、大庆市人民医院、大庆市第五医院3家医院确诊为痛风的中青年患者，信息饱和后停止招募，共招募13例患者。采用非结构式与半结构式访谈相结合的方式对患者资料进行收集，采用Colaizzi的现象学资料分析方法进行分析。结果　对访谈资料进行分析，提炼如下主题：痛风患者的疾病感知能力〔包括对痛风的认知及知晓情况较差；严重的疼痛可影响痛风患者的生活质量；自我感知导致疾病发作或加重的原因为饮食习惯及生活方式等〕、就诊状况及行为（包括首次发病对疾病认识缺乏；就医体验不良）、痛风药物管理计划（包括药物选择依从性低、治疗方案的知晓及应对差）、痛风非药物管理计划（包括生活方式的调整、社会资源互动、疾病信息挖掘）。结论　东北地区中青年痛风患者健康素养水平较低，对疾病相关信息获取途径单一，对疾病和治疗判断片面，因此不能有效进行疾病管理，阻碍医疗决策制定。提示根据需求状况、针对具体薄弱环节提升痛风患者的健康素养、提高知识水平对改善患者健康结局很有必要。     

CT扫描在胸膜外孤立性纤维瘤中的诊断价值

目的探讨CT扫描在胸膜外孤立性纤维瘤(E-SFT)中的诊断价值。方法回顾性分析2015年4月至2018年4月于我院接受手术治疗的90例E-SFT患者术前CT检查影像资料和术后病理、免疫组织化学资料,评估CT检查在E-SFT诊断中的应用价值。结果 90例E-SFT患者均为单发肿瘤,免疫组织化学及病理学检查示良性80例,恶性10例;CT检查结果为良性72例,平扫表现为圆形或类圆形软组织密度影,密度不均匀,大部分边缘清晰,增强扫描表现为均匀强化;恶性18例,平扫示肿瘤体积较大,边界不清,密度不均,可见大片不规则低密度区,增强扫描瘤体强化不均匀,低密度区无明显强化;CT诊断的敏感度、准确度、特异性阳性率、阴性率分别为60%(6/10)、82%(74/90)、85%(68/80)、33%(6/18)、94%(68/72)。结论 E-SFT的CT检查影像图像具有一定的特征性,尤其是增强扫描有助于评估纤维瘤的良恶性,可将其作为术前诊断及术后复查评估的有效依据用于临床诊疗工作中。     

关节镜联合关节牵张成形术治疗踝关节创伤性关节炎

目的对比分析单纯关节镜手术与关节镜手术联合Ilizarov外固定架关节牵张术治疗踝关节创伤性关节炎的临床疗效。 方法纳入2016年10月至2018年4月聊城市中医医院收治的早中期踝关节创伤性关节炎患者30例，排除非创伤性关节炎和终末期踝关节炎。其中接受单纯踝关节镜手术者纳入对照组(n＝15)，接受关节镜手术联合Ilizarov外固定架关节牵张成形术者纳入研究组(n＝15)，术后随访6个月，对比分析两组患者的治疗效果：疼痛视觉模拟评分(VAS)、踝关节功能评分(Kofoed评分)以及生活质量的变化。计数资料比较采用卡方或Fisher精确检验，计量资料比较采用独立样本t检验。 结果研究组治疗有效率大于对照组(χ²＝7.214，P<0.05)，术后疼痛视觉模拟评分明显低于对照组(t ＝10.342，P<0.05)，Kofoed评分高于对照组(t ＝10.452，P<0.05)；研究组生活质量显著高于对照组(P<0.05)。 结论关节镜手术联合关节牵张成形术对早中期踝关节创伤性关节炎较单纯关节镜手术短期效果更好，可成为临床治疗中的一种选择，但远期效果尚需进一步研究。     

二维斑点追踪技术评价低温兔左室纵向功能

目的:探讨应用二维斑点追踪技术评价低温条件下兔左心室纵向功能的价值。方法:30只新西兰兔随机分成对照组(n=10),低温组A(n=10),低温组B(n=10)。先行常规心脏数据测量,然后采用组织多普勒(TDI),之后应用斑点追踪成像(STI)中的获取基底段、中间段、心尖段及整体水平SL、SrLs.SrL E,SrL A及分层应变技术获取3个长轴切面心内膜下、中层和心外膜下心肌收缩期纵向峰值应变(SL)。结果:①与对照组相比,A组心内膜下心肌LS值的减低,差异有统计学意义(P<0.05),B组3层心肌SL值的减低明显,差异有统计学意义(P<0.01)②与对照组相比,A组大部分纵向应变及应变率减低(P<0.05);B组基底段、中间段、心尖段及整体水平SL,SrL S、SrLE、SrLA均减低(P<0.01)结论:随低温时间延长,左室壁3层心肌SL值受累程度不同,心内膜应变较心外膜更加敏感,二维班点追踪技术比LVEF及TDI更早发现左室功能减低。     

Epidemiology of gout and hyperuricemia in New Caledonia

ObjectivesNew Caledonia is a Pacific island of 270,000 inhabitants with mixed ethnicities, including Polynesians (10.2%), people from European ancestry (27.2%), and Melanesians (39.1%),. This study aimed at determining the prevalence of gout and hyperuricemia in the general population and the various ethnicities of New Caledonia.MethodsA 3-degree random sample of the population aged 18 to 60 years was adjusted according to the 2014 New Caledonia census. Face-to-face planned interviews and physical measurements were performed by trained nurses. All consenting participants underwent capillary measurement of creatinine; all consenting men and only women older than 40 years underwent point-of-care uricemia testing. Gout was defined by a validated algorithm. Two definitions of hyperuricemia were used: capillary level equivalent to plasma uric acid level > 360 μmol/l (6 mg/dl) and > 420 μmol/l (7 mg/dl) and/or urate-lowering drug treatment for both thresholds.ResultsWe included 1144 participants (adjusted mean age 37.7 ± 12.0 years; adjusted sex ratio 50.4% men). The adjusted prevalence of gout was 3.3% (95% confidence interval 2.2–4.9). Prevalence was 6.7% (2.5–16.8), 4.1% (1.8–8.9), and 2.6% (1.4–4.7) for Polynesians, Europeans and Melanesians, respectively, and 1.9% (0.5–6.6) for other ethnicities. Prevalence of hyperuricemia, determined in 658 participants, was 67.0% (61.9–71.6) and 37.0% (32.3–42.0) for the 360- and 420-μmol/l thresholds, respectively, and was significantly greater for Polynesians and Melanesians than Europeans for both thresholds.ConclusionsThe prevalence of gout and hyperuricemia in New Caledonia was high, including in patients of European descent.
