Objective:To determine the clinical implication of and intestinal carriage with methicillin resistant Staphylo-coccus aureus (MRSA)and extended spectrum β-lactamase (ESBL)-producing Enterobacteriacae.Methods:A total of 180 stool specimens were screened for MRSA and ESBL-producing enterobacteria .Identification of ESBL-producing Enterobacteriacae was done by MicroScan Walk Away 96 system (Dade Behring Inc.,West Sacramento,CA 95691,USA )and confirmation by double-disc synergy test.MRSA was identified by disc diffusion using 30 μg cefoxitin disc and the MicroScan.Results:The rate of fecal MRSA carriage was 7.8%(14 /180),35.7% (5 /14)were recovered from surgical wards.Three patients (21.4%)had MRSA recov-ered from other body sites,and 2 (14.2%)had in addition ESBL -producing Escherichia coli (E.coli)and Klebsiella pneumoniae (K.pneumoniae)respectively.Four (28.5%)patients with MRSA fecal carriage died. MRSA fecal carriage was recovered from both inpatients and outpatients.Four (2.2%)cases carried ESBL-producing Enterobacteriacae in feces .Three (75%)were from intensive care unit (ICU).One patient had both ESBL-producing E.coli and K.pneumoniae from stool as well as E.coli from tracheal aspirate .Two ICU patients with fecal ESBL died.Conclusion:Fecal screening for MRSA and ESBL of all patients at high risk admitted to different hospital wards and ICUs and implementing infection control measures were recommended.

药源性干眼症可致眼表潜在损伤,主要临床表现为眼部干涩、烧灼感、异物感、眼痒、眼红、畏光、视物模糊等,影响患者生活质量。引起药源性干眼症的药物包括全身使用的抗胆碱能药物如抗精神病药、抗组胺和减充血剂、激素、化疗药、抗病毒药、抗疟疾药、抗风湿药、螯合剂、神经毒素;眼周及眼局部使用的含或不含防腐剂的滴眼液及肉毒素等。药源性干眼症的发病机制与上述药物导致腺体分泌减少、影响水液层和黏蛋白层分泌、干扰泪膜脂质
神经内分泌肿瘤(NETs)是一组具有不同形态和生物学行为的罕见异质性肿瘤。由于其罕见性和异质性,在改善其诊断与治疗方面的研究进展缓慢。胰腺神经内分泌肿瘤(pNETs )是NETs家族中的一员,以前被称为胰岛细胞瘤,年发病率在(1~2)/10万,约占原发性胰腺肿瘤的3%。提高pNETs的诊疗技术很有必要。
自身免疫性胰腺炎(AIP)根据病变累及范围可分为弥漫性和局灶性,其中局灶性AIP的影像表现与胰腺癌非常相似,常常误诊,导致不必要的手术切除。本研究报道2例影像误诊为胰腺癌,经超声内镜下穿刺病理证实为局灶性AIP伴腹膜后纤维化。影像学上局灶性AIP累及的胰管呈炎症性狭窄,并无截断梗阻,上游胰管节段性轻度扩张;增强后呈渐进性延迟强化,强化程度高于胰腺癌。结合胰腺外IgG4相关性疾病可进一步提高诊断准确
