浅析病案缺陷及其防范措施

在新形势下,全国各地实行了医疗、保险制度的改革.规范病案管理,提高病案的管理质量显得更为重要.如何使病案管理更科学、更规范,使病案管理在法律的监督下制度更健全;如何减少病案缺陷的出现,防止医疗纠纷的发生,是医院面临的新课题.     

从疾病构成比谈医院发展

医院住院病人疾病构成比,是从量上显示在特定范围内的某一疾病的患病比重,是一个不可忽视的统计指标,能了解医疗需求变化趋势,为医院床位、人员的配备、拟就工作规划及调整医院服务工作等方面提供重要信息,是医院管理工作的重要指标.本文就我院近五年的住院疾病构成作一个简要分析.     

胸部螺旋CT最大密度投影重建的参数优化

目的探讨胸部螺旋CT最大密度投影(MIP)重建合理的扫描和重建参数。方法6例煤工的尸检离体肺脏制成充气固定肺标本,分别行不同参数组合的螺旋CT扫描,包括层厚1.5mm,2mm,4mm及8mm,重建间隔1mm,3mm,5mm;曝光量150mA,100mA;螺距1.5;滤过算法包括标准、锐利和平滑3种。每组图像均行MIP重建,重建厚度为12.5mm～13mm,比较不同参数MIP重建图像对支气管血管束的显示。结果a)曝光量对MIP重建图像的影响甚微,150mA、100mA两组剂量MIP无显著性差异(P>0.05);b)重建算法对MIP重建无显著影响。c)扫描层厚影响MIP图像,以薄层(1.5mm)扫描重建为最佳,1.5mm、2mm、4mm层厚MIP图像之间无显著性差异(P>0.05),8mm层厚与前4者MIP图像有显著性差异(P<0.01)。d)重建间隔影响MIP重建效果,8mm层厚扫描,1mm和5mm重建间隔重建图像MIP之间有显著性差异(P<0.05)。结论影响MIP重建的参数主要为扫描层厚和重建间隔,薄层扫描可获得理想的MIP图像,随层厚的增加,减小重建间隔有利于获得理想的MIP图像。建议以中等层厚(4mm)扫描,小重建间隔(1.5mm,2mm)行MIP重建。     

Agilent 2100 Bioanalyzer在人乳头瘤病毒检测中的应用

目的：探讨Agilent2100Bioanalyzer芯片分析系统（简称Bioanalyzer)在人乳头瘤病毒（HPV）的PCR检测和分组中的应用。方法：先分别进行通用引物介导PCR（GP－PCR）和型特异性引物介导PCR，扩增HPV高保守区（L1区）的共同序列和各型（包括HPV6，11，16和18型）的特型性序列，然后分别用常规的琼脂糖凝胶电泳技术和Bioanalyzer对PCR产物进行检测，并比较两种检测方法的准确度，重复性和灵敏度。结果：Bioanalyzer在确定片段长度时的准确度和重复性比琼脂糖凝胶电泳高，前者的准确度在95％以上，后者仅为85％，Bioanalyzer的检测灵敏度比琼脂糖凝胶电泳高100倍，结论：Bioanalyzer芯片分析系统结合PCR方法可对HPV进行特异，准确，稳定，灵敏的检测和型别鉴定，具有重要的推广价值。     

Comparison of Minimum Alveolar Concentration between Intravenous Isoflurane Lipid Emulsion and Inhaled Isoflurane in Dogs

Background: As in inhaled isoflurane anesthesia, when isoflurane lipid emulsion (ILE; 8%, vol/vol) is intravenously administered, the primary elimination route is through the lungs. This study was designed to determine the minimum alveolar concentration (MAC) and the time course of washout of isoflurane for intravenously infused ILE by monitoring end-tidal isoflurane concentration.

Methods: Twelve healthy adult mongrel dogs were assigned randomly to an intravenous anesthesia group with 8% ILE or to an inhalation anesthesia group with isoflurane vapor. An up-and-down method and stimulation of tail clamping were used to determine MAC of 8% ILE by intravenous injection in the intravenous anesthesia group and MAC by the inhaled approach in the inhalation anesthesia group, respectively. Isoflurane concentration and partial pressure in end-tidal gas, femoral arterial blood, and jugular venous blood were measured simultaneously just before each tail clamping and during washout.

Results: The induction time in the intravenous anesthesia group (105 +/- 24 s) was shorter than that in the inhalation anesthesia group (378 +/- 102 s; P < 0.01). MAC of 8% ILE by intravenous injection (1.12 +/- 0.18%) was significantly less than MAC by the inhaled approach (1.38 +/- 0.16%; P < 0.05). No significant difference was found between the two groups in the time course of washout of isoflurane.

The results of topical application of 13-cis-retinoic acid on basal cell carcinoma. A correlation of the clinical effect with histopathological examination and serum retinol level

A group of 50 patients with basal cell carcinoma of the face was treated by 13-cis-retinoic acid. The treatment resulted in diminution of the tumors. Complete regression was observed in 4 cases. Histological examination revealed necrosis of cancer cells and mononuclear infiltration into the treated tumors. In the group with weak clinical and histological reaction to the treatment all basal cell carcinomas were of adenoid type. A better effect was observed in the group with lower serum retinol level. This treatment method seems to be supplementary to surgery in prevention of the tumor recurrence.     

50例甲状腺癌的临床病理分析

甲状腺癌是临床和病理易于误诊的恶性瘤之一,高分化甲状腺癌与甲状腺腺瘤很难鉴别,甲状腺癌的组织学分类和病理诊断标准至今尚未统一。本文根据50例甲状腺癌的临床病理分析,参阅有关文献,对甲状腺癌的诊断标准、鉴别诊断和地方性甲状腺肿与癌的关系进行讨论。
