Comparison of ultrathin bronchoscopy with conventional bronchoscopy for the diagnosis of peripheral lung lesions without virtual bronchial navigation

BackgroundFor the precise management of advanced lung cancers, bronchoscopy with a high diagnostic yield and abundant tumor specimens are required. In recent years, new devices and techniques have been rapidly developed, including the endobronchial ultrasound (EBUS) using a guide sheath, virtual bronchoscopic navigation (VBN), and ultra-thin bronchoscope (UTB), for the diagnosis of peripheral pulmonary lesions (PPLs). These techniques increase the diagnostic yield for PPL, thus requiring fewer biopsy specimens.VBN is generally not available at the city hospitals in Japan. In this study, using fluoroscopy without VBN, we studied whether the histologic diagnostic yield of radial EBUS for PPLs would be higher using a UTB (without guide sheath) or conventional bronchoscope (CB) (with guide sheath).MethodsWe retrospectively reviewed consecutive patients with suspected lung cancer who underwent bronchoscopy at the Hakodate Goryoukaku Hospital from April 2017 to March 2019. We analyzed 168 patients—102 using UTB and 66 using CB.ResultsThe diagnostic yields for PPL were significantly higher in the UTB group than in the CB group (74.5% vs. 59.1%; P = 0.04). The median examination time was significantly longer in the UTB group than in the CB group (24 vs. 20 min; P = 0.01). There were no statistically significant differences in the complication rate between the UTB and CB groups (3.9% vs. 3.0%; P = 0.69).ConclusionsUTB had a significantly higher tissue diagnostic yield than CB, without the use of VBN.     

颞叶癫痫发作间期PET-CT与VEEG检查对致癫灶的诊断价值比较

目的 比较分析颞叶癫痫发作间期正电子发射计算机断层显像（PET-CT）和视频脑电图（VEEG）检查对致癫灶的诊断价值。方法 回顾性分析2016年3月至2018年3月手术治疗的80例单侧颞叶癫痫的临床资料。另选取同期健康体检者30例作为对照。术前进行PET-CT和VEEG监测定位致痫灶，以术中监测结果为定位致痫灶的金标准。利用受试者工作特征（ROC）曲线评价PET-CT放射性分布不对称指数（AI）对颞叶癫痫致癫灶的诊断价值。结果 PET-CT、VEEG确定致癫灶的灵敏度分别为88.73%、47.89%，特异度分别为88.89%、66.67%。颞叶癫痫发作间期病灶侧AI显著高于非病灶侧（P<0.05），同时也显著高于健康体检者颞叶内侧AI（P<0.05）及颞叶外侧AI（P<0.05）。ROC曲线分析结果显示，AI=0.153诊断颞叶癫痫致癫灶的曲线下面积为0.730，95%置信区间在0.544~0.916。结论 颞叶癫痫发作间期PET-CT脑显像定位准确率优于VEEG，对手术治疗准确定位有很高的应用价值，且AI为0.153时诊断癫痫灶的效果最好。     

Intracranial thrombosed anastomosing hemangioma: Case report

An anastomosing hemangioma is a relatively new diagnosis of a benign vascular lesion that is typically found in the genitourinary tract. On imaging, anastomosing hemangiomas have a broad differential diagnosis and can resemble malignant lesions such as angiosarcoma. Here we present a case of a 33-year-old male with seizures who on imaging was found to have a presumed recurrent intracranial meningioma. After surgical resection of his lesion, this case was pathologically diagnosed as having anastomosing hemangioma. To our knowledge, this is the first report of a case of a thrombosed anastomosing hemangioma located at intracranial and intradural region.     

Litoplastia coronaria en lesiones calcificadas: registro multicéntrico de la práctica clínica

Introduction and objectivesCoronary lithoplasty (CL) is a balloon-based technique used to treat calcified lesions. This study reports the initial experience of treatment of calcified lesions with CL in an unselected and high-risk population.MethodsThis was a prospective, multicenter registry, which included all consecutive cases with calcified coronary lesions that underwent CL between August, 2018 and August, 2019. Exclusion criteria consisted of a target lesion located in a small vessel (< 2.5 mm) and the presence of dissection prior to CL. Quantitative coronary angiography and intravascular ultrasound/optical coherence tomography analysis were completed by an independent central core laboratory.ResultsThis registry included 57 patients (66 lesions). The population was elderly (72.6 ± 9.4 years) with high proportions of patients with diabetes (56%), chronic kidney disease (35%), and multivessel disease (84%). All lesions were classified as type B/C. More than 75% of lesions were predilated with noncompliant/semicompliant balloons or cutting-balloon. Rotablator was used in 5 lesions (7.6%) prelithoplasty. On average, CL required 1.17 balloons delivering a mean of 60 pulses. Successful CL was achieved in 98%. In 13% of cases, lithoplasty balloon was broken during therapy. There were few procedural complications: 2 cases of significant dissections (none related to lithoplasty balloon rupture) were successfully treated with drug-eluting stent implantation. One patient experienced stent thrombosis 2 days after successfully undergoing target lesion revascularization.ConclusionsThis is a real-world multicenter registry, which supports the feasibility, safety, and short-term efficacy of PCI for calcified coronary lesions using CL in an unselected and high-risk population with promising results.     

超分子水杨酸治疗痤疮的效果及对皮肤屏障的影响

目的:观察超分子水杨酸对于痤疮的疗效及皮肤屏障的影响。方法:采用随机对照实验。选取痤疮患者40例,随机分为实验组和对照组,每组20例。实验组:给予30%超分子水杨酸换肤治疗,1周1次并配合外用特护霜,共治疗4次;对照组:仅每日给予特护霜外用。疗程结束4周后随访观察。治疗前及随访时使用CK无创皮肤检测仪检测两组患者面部皮肤生理指标,计数面部皮损。使用VISIA皮肤分析仪拍照留存。结果:实验组总有效率90%,对照组总有效率15%,两组比较有显著性差异(P<0.05)。同治疗前相比,实验组治疗后经皮水分丢失量(TEWL)、红斑值、角质层含水量及p H值均有改善,差异均有统计学意义(P<0.05)。与对照组比较,实验组治疗后TEWL、角质层含水量及p H值均有改善,差异均有统计学意义(P<0.05)。两组患者均未出现色素沉着、瘢痕等不良反应。结论:超分子水杨酸治疗痤疮疗效确切,同时具有修复皮肤屏障的作用。
