双侧延髓内侧梗死临床分析

目的分析并探究双侧延髓内侧梗死(BMMI)的血管病因、临床表现、MRI特征和预后,以期提高BMMI的早期诊断率.方法对青岛大学附属烟台毓璜顶医院诊治的14例BMMI患者临床资料进行分析.结果BMMI血管病因以动脉粥样硬化为主;临床症状表现为四肢瘫痪、舌瘫、感觉异常、头晕、构音障碍、饮水呛咳等,危重时出现呼吸衰竭.头颅DWI示双侧延髓内侧可呈特征性"心型"、"Y"字型、"V"字型或倒"八"字型高信号影.出院NIHSS评分、卒中进展(尤其呼吸衰竭)为BMMI的预后不良因素.结论BMMI临床少见,临床表现多样,预后较差;头颅MRI为其主要的影像学检查,有助于早期诊断.

经肺泡灌洗液宏基因组测序诊断肺隐球菌病一例并文献复习

肺隐球菌病(pulmonary cryptococcosis,PC)是由于患者吸入了环境中新生隐球菌或格特隐球菌后导致肺部感染而形成,是一种在临床上呈现亚急性或慢性感染的机会性疾病。常见于免疫功能低下患者,如传统免疫功能低下患者有血液系统肿瘤、长期使用免疫抑制剂或糖皮质激患者、后天获得性免疫缺陷综合征患者等。但是,近年的流行病学调查发现部分没有免疫抑制的患者也可能罹患PC约有1/3的肺隐球菌病发生在非免疫缺陷的健康人群。而在临床诊疗中肺隐球菌病患者的临床表现、实验室检查、影像学检查均相对缺乏特异性,非常容易被误诊为肺癌、转移性肿瘤、肺结核等疾病。本文回顾性分析一例经肺泡灌洗液行宏基因组测序确诊PC患者的临床资料,以增强临床对PC的诊断和认知能力,并最终提高临床确诊率。     

Using arterial spin labeling blood flow and its histogram analysis to distinguish early-stage nasopharyngeal carcinoma from lymphoid hyperplasia

To investigate the feasibility of arterial spin labeling (ASL) blood flow (BF) and its histogram analysis to distinguish early-stage nasopharyngeal carcinoma (NPC) from nasopharyngeal lymphoid hyperplasia (NPLH).Sixty-three stage T1 NPC patients and benign NPLH patients underwent ASL on a 3.0-T magnetic resonance imaging system. BF histogram parameters were derived automatically, including the mean, median, maximum, minimum, kurtosis, skewness, and variance. Absolute values were obtained for skewness and kurtosis (absolute value of skewness [AVS] and absolute value of kurtosis [AVK], respectively). The Mann–Whitney U test, receiver operating characteristic curve, and multiple logistic regression models were used for statistical analysis.The mean, maximum, and variance of ASL BF values were significantly higher in early-stage NPC than in NPLH (all P < 0.0001), while the median and AVK values of early-stage NPC were also significantly higher than those of NPLH (all P < 0.001). No significant difference was found between the minimum and AVS values in early-stage NPC compared with NPLH (P = 0.125 and P = 0.084, respectively). The area under the curve (AUC) of the maximum was significantly higher than those of the mean and median (P < 0.05). The AUC of variance was significantly higher than those of the other parameters (all P < 0.05). Multivariate analysis showed that variance was the only independent predictor of outcome (P < 0.05).ASL BF and its histogram analysis could distinguish early-stage NPC from NPLH, and the variance value was a unique independent predictor.
