简介:【摘要】目的:探究分析在普外科护理教学中采取以问题为导向的教学方法应用效果。方法:从2018年2月至2020年2月我院普外科护理实习生中抽选108名,采用数字随机分配法将其分为两组,实验组55名,采取以问题为导向的护理教学方法,对照组53名,采取常规教学法,对比两组临床护理教学效果。结果:两组内容理解评分无明显差异,P>0.05;实验组注意力、知识记忆深刻、参与情况、师生交流、协作能力、知识灵活应用、自主思考、思维拓展、表达能力等评分均明显高于对照组,且实验组理论成绩、实践操作成绩和总成绩均明显高于对照组,P
简介:[ 摘要 ] 报告 1 例水光针注射术后继发带状疱疹。患者女, 38 岁,水光针注射术后 11 天,左侧额面部红斑、水疱伴疼痛 5 天。通过对本例的分析总结,对我们今后临床工作中水光针注射术后不良反应的防治有一定意义。

简介:【摘要】目的:结合2019版WHO消化系统肿瘤分类对阑尾杯状细胞腺癌的研究,分析1例以右侧盆腔包块为首发症状的阑尾杯状细胞腺癌的临床特点,病理特征和免疫表型。方法:回顾性分析1例阑尾杯状细胞腺癌伴右侧卵巢转移的临床特点,组织学特征,免疫表型分析及复习相关文献进行讨论。结果:女性,年龄48岁,行右侧卵巢切除,术中冰冻结果(右侧附件)间质内见大量印戒样细胞浸润,低分化癌浸润或转移不能除外。与临床沟通建议检查胃肠道及阑尾。追加阑尾切除,术中冰冻结果(阑尾)见印戒样细胞浸润,杯状细胞腺癌可能,切缘阴性。术后常规病理显示典型的杯状细胞腺癌成分。免疫组化:CK7,CK20,SYN,CgA,CD56均阳。结论:阑尾的杯状细胞腺癌是一种少见肿瘤,大部分没有明确的肿块,术前检查难以发现阑尾病变。以盆腔包块为首发症状,冰冻中见大量印戒细胞时,要考虑到阑尾的杯状细胞腺癌可能,找到原发病灶,为临床进行正确的手术方式提供依据。
