急性胰腺炎病因和诊治十年变迁(附725例报道)

急性胰腺炎的病因和早期诊治一直是临床医师关注的问题。目的：探讨近十年来急性胰腺炎病因、诊断和治疗的变迁及其对预后和住院费用的影响，总结急性胰腺炎的治疗经验。方法：采用回顾性临床研究方法，将725例人选患者分为两组．1993年4月～1998年12月就诊的患者为第一组，1999年1月～2002年8月就诊的患者为第二组：分析两组患者病因、诊断指标、治疗方案、并发症、预后、住院费用方面的变化。结果：比较两组病因，两组患胆囊炎胆结石者分别占72．3％和75．8％，高脂血症者分别占25．3％和25．8％，酗酒者分别占10．6％和9．7％。血清淀粉酶水平高于正常上限3倍的总检出率为66．9％．CT诊断总阳性率为92．0％。第一组46．9％的患者应用生长抑素，31．1％的重症患者发生胰腺假性囊肿，2．2％发生胰腺脓肿，死亡率为15．6％。第二组72-3％的患者应用生长抑素，13．2％的重症患者发生胰腺假性囊肿，2．2％发生胰腺脓肿，死亡率为6．5％。第二组的住院费用与第一组相比呈下降趋势，但无显著差异。结论：胆道疾病仍为急性胰腺炎的主要病因，血清淀粉酶和CT是急性胰腺炎较常用和可靠的检查手段。通过早期足量应用胰酶抑制剂(尤其是生长抑素)、肠道去污和改善胰腺微循环，可改善急性胰腺炎的预后，降低并发症发生率、死亡率和住院费用。     

护士礼仪课的教学与实践

传染病流行的社会因素及社会控制策略刍议

传染病与社会文化因素的关系密切。应重视社会因素对传染病的发生发展影响，从社会根源上探究其发病原理，包括经济因素、科学技术、文化、人口、卫生服务和其它社会因素。人类要有与传染病长期斗争的思想准备，并制定包括大卫生观和技术合作等相应的社会策略。     

改良Foerster-Dandy手术治疗痉挛性斜颈

目的 探讨改良Foerster-Dandy手术治疗痉挛性斜颈的疗效。方法 回顾分析2001年7月至2004年6月显微手术治疗的26例痉挛性斜颈病人，全部采用改良Foerster-Dandy手术，即枕后正中入路硬膜下双侧副神经根、C1脊神经根切断、C2～C4脊神经前、后根选择性部分切断术。结果 全部病人平均随访12．8个月。100％病人术后立即感痉挛状态明显缓解，随访期间缓解率为100％。生活质量提高率在随访期间为96％。术后所有病例发生不同程度转颈无力、耸肩无力、双臂外展受限，随访期间均有所好转，1例病人发生头颈部支撑困难，并因此而影响生活质量。随访期间无复发病例。结论 改良Foerster-Dandy手术是治疗痉挛性斜颈安全有效的手术方法。选择合适病例、熟悉局部解剖、掌握显微手术技巧是保证疗效的关键。     

Physical symptoms/side effects during breast cancer treatment predict posttreatment distress

Background: Studies suggest that the period following completion of treatment can be distressing for cancer patients. One potentially important predictor of distress is physical symptoms/side effects during treatment.Purpose: A longitudinal, observational design was used to examine whether the number of physical symptoms/side effects experienced during treatment was a correlate of cancer-related distress and general distress 4 months after treatment completion, as measured by the Impact of Events Scale and the Mental Health subscale of the Short Form-36, respectively.Methods: Participants were 151 women who had completed chemotherapy and/or radiotherapy for ductal carcinoma in situ or stage 1 or 2 breast cancer. Hierarchical multiple regression was conducted with relevant sociodemographic, clinical, and psychiatric variables entered as controls.Results: Greater physical symptoms/side effects predicted greater total cancer-related distress, intrusive thoughts, and general distress. Physical symptoms/side effects did not significantly predict avoidance. Follow-up analyses indicated that the relationship between physical symptoms/side effects and general distress was mediated by both total cancer-related distress and intrusive thoughts.Conclusions: These results suggest that patients who experience greater physical symptoms/side effects during treatment are at greater risk for later cancer-related distress and, in turn, general distress. Future research should evaluate whether early intervention with these patients is effective in preventing or reducing distress in the posttreatment period.

Prevalence of knee abnormalities in patients with osteoarthritis and anterior cruciate ligament injury identified with peripheral magnetic resonance imaging: a pilot study.

OBJECTIVES: 1) To assess, with a peripheral magnetic resonance imaging system (pMRI), the prevalence of bony and soft tissue abnormalities in the knee joints of normal subjects, osteoarthritis (OA) patients, and individuals who have suffered an anterior cruciate ligament (ACL) rupture; and 2) to compare the prevalence among groups. METHODS: Magnetic resonance (MR) images of 28 healthy, 32 OA, and 26 ACL damaged knees were acquired with a 1.0-T pMRI system. Two radiologists graded the presence and severity of 9 MR image features: cartilage degeneration, osteophytes, subchondral cyst, bone marrow edema, meniscal abnormality, ligament integrity, loose bodies, popliteal cysts, and joint effusion. RESULTS: Ten of 28 healthy (35.7%), 24 of 26 ACL (92.3%), and all OA knees (100%) showed prevalent cartilage defects; 5 healthy (17.9%), 20 ACL (76.9%), and all OA knees (100%) had osteophytes; and 9 normal (32.1%), 21 ACL (80.8%), and 29 OA knees (90.6%) had meniscal abnormalities. One-half of the knees in the OA group (16 of 32, 50%) had subchondral cysts, and almost one-half had bone marrow edema (15 of 32, 46.9%). These features were not common in the ACL group (7.7%, and 11.5%, respectively) and were not observed in healthy knees. The OA group had the most severe cartilage defects, osteophytes, bone marrow edema, subchondral cysts, and meniscal abnormalities; the ACL group showed more severe cartilage defects, osteophytes, and meniscal abnormalities than did normal subjects. CONCLUSION: The results suggest that knees that have sustained ACL damage have OA-like reatures; most subjects (19 of 26, 73.1%) could be identified as in the early stage of OA. The prominent abnormalities present in ACL-damaged knees are cartilage defects, osteophytes, and meniscal abnormalities.
