Clinical background of cases showing a positive culture of pleural effusion at Shin-Kokura Hospital over a period of 5 years

We investigated the clinical background of patients at Shin-Kokura Hospital who showed a positive culture of pleural effusion during the period from January 1998 through December 2002. Microorganism cultures of the pleural effusions of 127 patients were performed in this 5-year period. Seventeen patients showed a positive microorganism culture from a pleural effusion, and 12 of these patients (70.6%) were 60 years old or more. Ten patients were diagnosed with thoracic empyema. Thirteen patients had an underlying disease such as malignancy (5 cases), diabetes mellitus (4 cases), etc. A purulent effusion and a high concentration of lactic dehydrogenase (LDH) in the pleural fluid were more frequently recognized in the positive-culture group. A total of 21 strains of microorganism were isolated from the 17 patients, including 10 strains of Gram-positive cocci, 6 strains of Gram-negative bacilli, 3 strains of anaerobes, 1 strain of mycobacterium (Mycobacterium tuberculosis), and 1 strain of fungus. Susceptibility to antimicrobial agents was generally good for most of the microorganisms isolated. Of the 17 patients, chest-tube drainage was performed in 13, and 6 needed a surgical operation. Twelve patients improved, but 5 died. In this study, thoracic empyema accounted for 58.8% of the 17 cases with a positive culture of pleural effusion. Of the 10 thoracic empyema patients, 5 patients needed surgical treatment in spite of adequate antimicrobial treatment and chest-tube drainage. Our data indicate that thoracic empyema is still difficult to treat, and thus adequate and rapid treatment is needed for any pleural infection.     

168例食管烧伤后瘢痕狭窄的预防和治疗

目的 总结食管烧伤后瘢痕狭窄预防和治疗的经马命。方法 168例中158例进行了172次外科治疗，11例进行了2次以上手术。早期人院Ⅱ度期以上34例采用改良食管腔内置管预防食管烧伤后瘢痕，末切除瘢痕狭窄结肠重建77例，切除狭窄食管胃重建27例，颈阔肌皮瓣修复颈部食管狭窄22例，其他类型手术12例。结果 29例拔出支撑管后治愈（85％）；5例再狭窄，其中1例扩张治愈。77例结肠重建术后5例死亡，颈部吻合口瘘14例，吻合口狭窄4例，腹部切口裂开2例。27例胃重建中，吻合口狭窄2例。脓胸1。颈阔肌皮瓣修复颈段狭窄22例中，3例发生颈部瘘。其他手术12例中，1例术后死于肠梗阻。所有生存出院患者均能进普食。 结论 管腔内置管能有效预防食管烧伤后瘢痕形成，根据瘢痕狭窄部位确定食管重建时是否切除狭窄食管。颈阔肌皮瓣是修复颈段食管狭窄或吻合口狭窄的优良方法。

64排螺旋CT冠状动脉造影与DSA的对照研究

目的:通过和冠脉造影对比,评价64排螺旋CT冠状动脉成像在冠状动脉狭窄中的临床应用价值。方法:28例患者同时行64排螺旋CT冠状动脉成像和有创性冠脉造影检查,依据AHA17段分段法,评价所有有效节段,并将两者进行对比。结果:冠脉造影显示阴性病例占7.1%(2例),单只病变占21.4%(6例),多支病变占71.4%(20例)。按节段分析,CT检出冠脉狭窄的敏感度,特异度,阳性预测值和阴性预测值分别为91.1%,94.6%,90.0和95.3%。结论:64排螺旋CT冠状动脉成像和传统的冠脉造影检查对检出正常冠脉节段以及狭窄节段具有很好的一致性。

Vertebral body replacement system Synex in unstable burst fractures of the thoracic and lumbar spine

A prospective longitudinal study was performed to evaluate the vertebral body replacement system Synex associated with posterior fixation in unstable burst fractures of the lumbar and thoracic spine. Within 24 months, we treated 28 patients (average age, 41 years; range, 22–64 years; 14 women, 14 men) with acute unstable burst fractures without osteoporosis of the thoracolumbar region (n=16) and the thoracic (n=3) as well as the lumbar (n=9) spine in two stages (primary dorsal transpedicular stabilization and secondary vertebral body replacement). The complications were analyzed and the postoperative follow-up result was evaluated regarding stability, bone fusion, correction loss, pain and neurological status. One patient showed a transient irritation of the lumbosacral plexus and one patient had a superficial wound infection (complication rate, 7.1%). At the follow-up examination (mean follow-up, 13 months) only in two cases a minimal loss of correction (<5°) was measured. Radiologically, 27 patients showed secure bone fusions and all patients had stability of the osteosynthesis. Most of the patients stated no or just slight pain at follow-up. Only two patients with pain to a medium degree had to take painkillers. The vertebral body replacement system Synex seems to be a good alternative for vertebral body replacement in unstable burst fractures of the thoracic and lumbar spine since at present follow-up it shows a high rate of bone fusion and minimal loss of correction.     

氟伐他汀对老年动脉粥样硬化所致肾动脉狭窄的临床疗效观察

目的观察氟伐他汀对老年肾动脉粥样硬化所致肾动脉狭窄(ARAS)的治疗作用及其抗炎机制。方法将在我院门诊及住院的54例老年ARAS患者,随机分为治疗组及对照组,对照组给予常规降压治疗,治疗组每晚加服氟伐他汀40 mg。比较两组治疗前及治疗后尿蛋白排泄率(UAER)、血肌酐(Scr)、C反应蛋白(CRP)及肾脏血管多普勒超声中肾动脉收缩期峰值速度(PSV)、肾动脉血流加速度时间(AT),肾动脉峰值流速与肾动脉开口处腹主动脉流速之比(RAR)等指标。结果观察期间,两组上述指标均呈下降趋势,治疗组UAER,PSV,AT,RAR下降较对照组明显(P<0.05,P<0.01),治疗组CRP下降明显(P<0.05,P<0.01),对照组CRP变化不明显(P>0.05)。而且在两组血脂正常的老年ARAS所致肾动脉狭窄的患者进行比较分析也得出类似结果。结论氟伐他汀因降低CRP的致炎效应而改善肾动脉狭窄,且不依赖氟伐他汀的降血脂作用。
