Introduction: The purpose of this study was to assess velocity-encoded cardiac magnetic resonance imaging (Ve-CMR) in a population of patients referred for cardiac magnetic resonance imaging (CMR), to determine the variability of atrial function, and to identify clinical parameters associated with left atrial function. Methods: This is a prospective study evaluating patients who were referred to our CMR center for a clinical CMR. Left atrial function was obtained via Ve-CMR thru-plane images across the mitral valve after acquiring 2 perpendicular in-plane images as “scouts”. The atrial function and mitral inflow were quantified by computer analysis (Argus, Siemens). Atrial function was defined as atrial contraction (A-wave) volume divided by total inflow volume. Left atrial volumes were calculated via computer analysis. Mitral regurgitation and left ventricular ejection fractions were assessed visually. Results: Thirty-nine patients, with mean age 56 +/- 10 years, were enrolled. The mean left atrial function was 22.9% +/-14.5%;the range in left atrial function was 0% - 57%. There was a significant positive correlation between atrial function and increased left ventricular ejection fraction (r = 0.44, p p p = 0.02). Conclusion: Our results indicate a wide variability in left atrial function and a significant association between left atrial function and left ventricular ejection fraction, left atrial volume and mitral regurgitation.

Anomalies of the epididymis are most commonly associated with an undescended testis but also found occasionally in a normally descended testis. Our 11- year-old patient presented with an acute scrotum and Doppler ultrasound that suggested epididymitis. painful symptoms required scrotal exploration with the finding of a torsion and infarction of the epididymis. The etiology of the torsion was an abnormal attachment of the epididymis to the testis. Torsion of the epididymis has not previously been reported.

目的比较MR成像与眼底镜检查对视网膜母细胞瘤分期的诊断价值。方法经机构审查委员会批准,回顾性评估36例接受眼球摘除术病人的MR及眼底镜影像。以组织病理学作为参考标准,比较两种诊断方法对于生长方式、虹膜新生血管、视网膜脱落、玻璃体种植及视神经侵犯的敏感性和特异性。通过McNemar’s检验对数据进行分析。结果两种方法检测不同的肿瘤生长方式的准确度差异无统计学意义（p=0.80）。眼底镜对于玻璃体种植的检出优于MRI（p<0.001）。对于巩膜筛板前视神经受累,MR成像与眼底镜检查敏感度相似,但特异度增加[40%（CI:0.12～0.74）∶20%（CI:0.03～0.56）]。MRI检测视神经受累突破巩膜筛板的敏感度为80%（CI:0.28～0.99）,特异度为74%（CI:0.55～0.88）。视神经无强化可排除组织病理学浸润,但视神经强化具有很高的假阳性率（22%24%）。结论眼底镜检查仍然是确定球内肿瘤范围的方法,而MR成像有助于评估球外肿瘤的范围。因此,两种检查方法对于视网膜母细胞瘤的分期各具优势和特点。要点①眼底镜检查是确定视网膜母细胞瘤球内范围的首选方法。②MR成像可以很好地评估巩膜外和球外肿瘤的范围。③MRI上视神经的强化不一定表明其受累。

purpose: A prospective study to evaluate the macular structural and functional effects of pars plana vitrectomy (ppV) for persistent diffuse clinically significant macular oedema (CSMO). Method: A total of 12 patients with persistent diffuse CSMO were recruited and underwent assessment including best-corrected visual acuity, fundus fluorescein angiography, optical coherence tomography (OCT) and fine matrix mapping (FMM)at baseline and over a period of a year poststandard three-port ppV. Results: The median baseline ETDRS letters score for all 12 patients was 52 (range 41-63) while at 12 months it had increased to 65 (range of 27-68), an improvement of two complete ETDRS lines (p=0.037). Similarly, there was an improvement in the perifoveal cone thresholds (p=0.02). The foveal thickening for all 12 patients ranged from a median of 183 to 751μm (normal range 126-180 μm) and the macular volume ranged from a median of 2.13 to 6.42mm3 (normal p=0.01). On baseline OCT, the patients fell into two anatomically distinct groups: Group 1 (n=4) had a dome-shaped thickened macula with a partial posterior hyaloid separation and a significantly higher foveal thickness and macular volume than Group 2 (n=8)which had a diffuse low-elevation profile of the thickened macula (p=0.007). Conclusions: In this prospective study of ppV for persistent fovea-involving CSMO there was structural and functional improvement.

Introduction: Focal macular photocoagulation for clinically significant macular oedema (CSME) is the proven method for treatment of this condition, but with little chance of visual improvement. pars plana vitrectomy (ppV) may produce resolution of macular oedema and improvement in visual acuity. However, there have been no randomised trials to ascertain role of vitrectomy in the management of persistent CSME. Methods: patients with persistent CSME despite previous macular photocoagulation and Snellen visual acuity 6/15 to 6/60 were recruited. Dilated fundoscopy, best-corrected visual acuity including Early Treatment Diabetic Retinopathy Study (ETDRS) vision, ocular coherence tomography and fundus fluorescein angiography (FFA) at baseline and up to 12 months post-treatment was performed. Exclusion criteria were signs of posterior vitreous detachment, macular traction or the taut posterior hyaloid face syndrome, or macular ischaemia on FFA. In all, 20 patients were randomised (10 in each arm) to either standard macular photocoagulation or ppV and removal of the posterior hyaloid face. Results: Of the 20 patients recruited, seven patients completed the protocol in the vitrectomy and eight in the laser arms, respectively. There was little evidence of any difference in the foveal thickness at 12 months between the two treatment arms despite a gradual improvement. Only one patient, from the vitrectomy arm, suffered moderate visual loss (defined as loss of 15 ETDRS letters) (our primary outcome). Discussion: In this pilot RCT, standard ppV provides little visual benefit compared tomacular photocoagulation,but a larger definitive study is required to confirmthis early appraisal.

目的评估乳头状肾细胞癌(pRCC)的MRI表现中的先兆性提示和病理学特征。方法共115例病人128处pRCC病变术前行MRI检查,观察病理学类型(1型或2型),MRI表现(局灶性或浸润性)和其他的MRI征象。根据是否出现转移性疾病将病人分组。结果共有65处病变为局限性1型,54处为局限性2型和9处为浸润性pRCC。所有的浸润性pRCC在组织病理学上均属2型。89%的浸润性pRCC出现肾静脉血栓,而局限性pRCC则无肾静脉血栓。3.7%的局限性1型,7.5%的局限性2型和75.0%的浸润性2型pRCC出现了转移。MRI上浸润性的表现是预测病变转移、独立的病理学类型、病变大小和T分期的重要因子(p≤0.020)。MRI表现为局限性pRCC病人中,病理学2型并非转移性病变的有效预测因子(p=0.648)。其他征象相结合在准确预测病变转移性时均不高于仅有肾静脉血栓一种表现(p>0.5)。结论以MRI上浸润性表现和肾静脉血栓为特征的组织病理学2型pRCC的亚型发生转移的风险显著增高。要点①MRI为术前认知肾细胞肾癌(RCC)提供了新的方法。②某些特定的MRI征象与转移性乳头状RCC具有相关性。③转移性病灶较易出现浸润性表现和肾静脉血栓。

Objective: The pilot study was intended to test the feasibility of a multiple-component lifestyle intervention targeting African American adults in a weight control and cardiometabolic risk reduction program on diet, activity, and stress, using community-engagement principles. Methods: Applying mixed qualitative and quantitative measures, the intervention had a two-part sequential study design consisting of 12 weekly small group sessions that provided individual and group counseling in nutrition, exercise, and mindfulness, while incorporating focus group and interactive techniques to learn about barriers and acceptable practices for this population. The program was implemented at an African-American church in Nashville, Tennessee. Results: Thirty-four participants (aged 56.1 ± 11 years, body mass index (BMI) 36.7 ± 6.6 kg/m2) completed the intervention. Lifestyle changes after the 12 weekly sessions showed some positive trends including reduced sodium intake (from 2725.3 ± 326.5 to 2132 ± 330, mg/day, p = 0.008), increased walking steps (from 4392.1 ± 497.2 to 4895.3 ± 497.9, steps/day, not significant), and slightly decreased perceived Stress Scale (pSS) scores (from 13.7 ± 1.4 to 12.4 ± 1.5, not significant). Body fat % among male participants decreased significantly (from 33.8 ± 2.6 to 28 ± 2.6, %, p = 0.043). Among cardiometabolic risk biomarkers, hemoglobin A1c (HbA1c) decreased significantly (from 6.6 ± 0.2 to 6.1 ± 0.2, %, p β = 2.4, p = 0.006). Twenty-one participants took part in focus groups during the program to identify barriers to healthy lifestyle changes. primary barriers reported were price, time for preparing healthy meals, unfamiliarity with mindfulness activities, their health condition, and daily schedule available for physical activities. Conclusions: This church-based pilot intervention was proven feasible by showing modest progress in reducing adiposity and decreasing HbA1c levels. The focus group and interactive methods facilitated program di
