Internal Hernias: Clinical Findings,Management, and Outcomes in 49 Nonbariatric Cases

Internal hernia, the protrusion of a viscus through a peritoneal or mesenteric aperture, is a rare cause of small bowel obstruction. We report the clinical presentation, surgical management, and outcomes of one of the largest series of nonbariatric internal hernias. Ten-year retrospective review of patients at our institution yielded 49 cases of internal hernias. Majority of patients presented with symptoms of acute (75%) or intermittent (22%) small bowel obstruction. While 16% of CT scans were suspicious for internal hernia, in no cases the preoperative diagnosis of internal hernia was made. The most frequent internal hernias were transmesenteric (57.0%) and 34 hernias (69%) were caused by previous surgery. All internal hernias were reduced and the defects were repaired. Compromised bowel was present in 22 cases and 11 patients underwent small bowel resection. The mean postoperative hospitalization was 10.9 days. The overall mortality rate from our series is 2%, and the morbidity rate is 12%. Transmesenteric hernias, as complications of previous surgeries, are the most prevalent internal hernias. Preoperative diagnosis of internal hernia is extremely difficult because of the nonspecific clinical presentation. However, if discovered promptly, internal hernias can be repaired with acceptable morbidity and mortality.

抗神经元抗体对副肿瘤综合征早期诊断的临床意义

目的 探讨抗神经元抗体抗-Hu、抗-Yo、抗-Ri抗体的检测与副肿瘤综合征早期诊断的关系。方法 采用蛋白免疫印迹分析(Western Blot)法对12例确诊为副肿瘤综合症(PNS)的患者血清及32例非PNS血清进行检测。结果 12例确诊患者血清中检测到一项或多项抗体阳性;PNS患者血清中抗-Hu、抗-Yo、抗-Ri抗体的阳性率高于非PNS对照组,差异有极显著性意义(P<0.01);正常对照组血清抗-Hu,抗-Yo,抗-Ri抗体全部为阴性。结论 抗神经元抗体抗-Hu、抗-Yo、抗-Ri抗体可作为PNS早期诊断及确诊的指标。     

Morphometric diagnosis of bladder tumor

This paper reports the morphometric analysis results of 100 cases of bladder tumor cells with a Q-900 computer-assisted image analysis system. According to the nuclear area, axis ratio and area ratio of tumor nuclei, bladder transitional cell tumors were divided into 4 grades. This system is called the morphometric grading system (M grading). The results show that the higher the M grading, the lower the survival rate and the higher the recurrence rate. As the M grade increases the tumors could be accompanied by muscular invasion. When recurring, the tumor has a poor prognosis if M grading increases. We conclude that the morphometric grading system is able to yield a quantitative pathologic diagnosis and can predict the biological behavior of bladder tumors. Recently, new techniques for diagnosing and predicting the biological behavior of bladder tumors have been developed. One such technique is morphometric analysis of bladder transitional cell carcinoma with computer-assisted image instruments [1]. Because this morphometric method is easily applicable to pathological section routinely stained with HE and the results are reproducible and more objective, the studies about morphometric analysis of bladder tumor have increased in recent times. This paper reports the preliminary morphometric analysis results of bladder tumor cells examined by a Q-900 image analysis instrument for 100 cases.     

上海市长宁区社区居民健康行为咨询点状况评估

目的了解社区居民健康行为咨询点现况,以进一步规范咨询点工作,为居民提供一流健康服务。方法采用资料法、现场观察法及问卷调查方法,对全区所有咨询点的硬件、软件配备情况、工作开展情况和规范程度以及咨询点服务对象对咨询点知晓情况、满意度进行综合评估。结果60.5%的咨询点工作完全达标;99.2%的居民知晓服务信息;97.8%的居民接受过咨询服务,居民对咨询点服务满意率达97.2%;分别有25.7%的咨询员、50.4%的居委干部、23.2%的居民提出增加服务时间、内容,改善服务条件等建议。结论调查对象对健康行为咨询点服务满意度逐年上升,但咨询点的整体服务水平还有待提高,特别在服务时间、服务内容以及服务条件等方面,还有待完善。     

The laterally extended medial hemisoleus flap for reconstruction of a tibial wound in the distal third of the leg

A soleus flap as a local reconstructive option for soft-tissue coverage of a tibial wound in the distal third of the leg has never been well recognized. In a 2-year period, seven patients underwent reconstruction of a less extensive tibial wound (4 × 3 to 10 × 4 cm) in the distal third of the leg after orthopedic trauma with the laterally extended medial hemisoleus flap. The flap was elevated with emphasis on the preservation of the most distal perforators from the posterior tibial vessels to the flap as possible while allowing adequate rotation of the flap to cover the exposed tibia and/or hardware and on the possible preservation of foot planter flexion by reconstruction of the proximal Achilles’ tendon. In this series, there was no total or partial flap loss. All patients healed their tibial wounds primarily with reliable soft-tissue coverage, evidenced fracture healing, and good cosmetic outcome during follow-up. Thus, the laterally extended medial hemisoleus flap described by the author can be a reliable option for soft-tissue coverage of a less extensive tibial wound in the distal third of the leg. It offers a more cost-effective approach for managing this unique problem and can be performed by most reconstructive surgeons without microsurgical expertise.     

南山区与某社区常住人口6年恶性肿瘤发病调查

目的：了解某社区常住人口恶性肿瘤平均年发病率是否高于周边人群，重点是白血病平均年发病率。方法：采用回顾性调查法及个案调查表收集该社区1998年6月～2004年9月常住人口中的确诊恶性肿瘤病人22例，将该社区恶性肿瘤平均年发病率与南山区在该时段恶性肿瘤平均的发病率进行比较。结果：1998年6月～2004年9月南山区常住人口恶性肿瘤平均年发病66．1／10万，某社区常住人口恶性肿瘤平均年发病率29．9／10万，两地差异有统计学意义（F=0．0001，P〈0．05）；南山区常住人口白血病平均年发病率2．79／10万，某社区常住人口白血病平均年发病率4．07／10万，两者无统计学意义差异（F=0．467，P〉0．05）。结论：该社区常住人口恶性肿瘤及白血病平均年发病水平低于南山区全区水平。
