大鼠脑出血后体感诱发电位的改变与脑水肿的形成

目的:使用体感诱发电位(SEP)对脑出血(ICH)模型进行评价,并观察ICH后不同时期脑水肿的形成过程。方法:采用脑立体定向术制备大鼠脑内囊出血的模型。观察大鼠在手术前及手术后不同时期内神经系统功能、SEP、脑组织形态学及脑组织含水量的改变。结果:与假手术组相比,实验组(6h、12h、1d、5d)、各波潜伏期延长(P<0.05),脑组织含水量增多(P<0.05);实验组(2d、3d)各波潜伏期明显延长(P<0.01),脑组织含水量明显增多(P<0.01);实验组(7d)各波潜伏期缩短(P>0.05),脑组织含水量减少(P>0.05)。脑组织形态学与神经系统功能呈现相应的改变。结论:SEP是评价脑立体定向术制备大鼠脑内囊出血模型的最客观指标,脑出血后脑水肿的形成是一个动态过程,SEP的改变与脑水肿的形成有直接的关系     

微量激光治疗糖尿病性黄斑病变的临床疗效

目的探讨微量激光治疗糖尿病性黄斑病变的临床疗效。方法将180例210眼临床确诊为轻至中度的背景型糖尿病性黄斑病变患者随机分为传统激光治疗组(90例108眼)和微量激光治疗组(90例102眼)。随访12个月,以三面镜裂隙灯显微镜、光学相干断层扫描仪(OCT)评估两组光凝前、后黄斑水肿严重程度、渗漏范围和硬性渗出的数量变化,同期进行视力、中心10°静态视野检查。结果术后12个月,传统激光治疗组中48例54 眼(50％)、微量激光治疗组中42例49眼(48％)OCT黄斑区厚度变薄。术后12个月在硬性渗出数量和程度上,传统激光治疗组好转54眼(50％),微量激光治疗组好转48眼(47％)。两组在OCT视网膜厚度、视力、视敏度等方面的改变均无明显差异(P>0．05)。结论微量激光与传统激光在治疗背景型糖尿病性黄斑病变方面的疗效相似。     

Massive ovarian edema associated with ovarian serous cystadenoma: a case report and review of the literature

Abstract.   Khalbuss WE, Dipasquale B. Massive ovarian edema associated with ovarian serous cystadenoma: a case report and review of the literature. Int J Gynecol Cancer 2006; 16(Suppl. 1): 326–330.
Massive ovarian edema is a rare entity that can be confused with an ovarian neoplasm. A few ovarian lesions have been reported that are associated with massive ovarian edema. This article describes the first case of an ovarian serous cystadenoma associated with a massive ovarian edema. The patient was a 17-year-old female who was referred to the emergency room because of lower abdominal pain. Subsequent ultrasound and computed tomography scanning studies revealed an abdominopelvic cystic mass suggestive of an ovarian neoplasm. She underwent an exploratory laparoscopy, and a left salpingo-oophorectomy was performed. The specimen weighed 1610 g and consisted of a cystic mass measuring 17 × 15 × 8 cm attached to a solid mass measuring 13 × 11 × 4 cm. Microscopy revealed a cystic and a solid lesion. The cystic structure was composed of a flat or cuboidal single-layer lining showing ciliated epithelium and focal areas of papillary structures compatible with a diagnosis of ovarian serous cystadenoma. The solid mass had an intact capsule and diffuse interstitial edema, preserving the overall structure of the ovary and sparing the outer cortex. These findings are compatible with the diagnosis of ovarian massive edema. This report of an association of serous cystadenoma with massive ovarian edema broadens the histologic spectrum in which a massive ovarian edema may be encountered.     

Critical management in patients with severe enterovirus 71 infection

OBJECTIVE: The aim of this study was to analyze clinical details occurring in children with severe enterovirus 71 (EV71) infection and synthesize the critical care experience for patients with severe EV71 infection. METHODS: A retrospective clinical, laboratory, and hemodynamic study was performed in a pediatric intensive care unit in a university hospital. From March 1998 to April 2000, seven consecutive pediatric patients with severe EV71 infection were retrospectively analyzed as the comparison group. From May 2000 to March 2003, eight consecutive patients with severe EV71 infection who had received the protocol therapy were enrolled as the study group. Detailed information about clinical treatment and pharmacological therapy was collected for comparison. RESULTS: The clinical presentations and laboratory findings between the comparison and the study groups were not significantly different. The amount of intravenous fluid in the first 24 h was significantly higher in the comparison group (9.2+/-5.0 vs 4.9+/-1.3 mL/kg per h). More patients in the study group received low doses of dopamine infusion, patients in the comparison group received more epinephrine, and none of them received milrinone. The acute-stage and long-term survival rates were higher in the study group (100% vs 43%, 87% vs 29%). CONCLUSION: Early cardiopulmonary support may prevent the vicious cycle of cardiopulmonary failure and improve the clinical outcome of severe EV71 infection. Milrinone may be the ideal inotropic agent for these patients. Echocardiography, a central line, and an arterial line could be an alternate method to replace direct intracardiac hemodynamic monitoring for guiding critical management.
