创伤病人的手术与焦虑状态调查

采用状态——特质焦虑问卷及１０项躯体性焦虑测试题，对４０例外科创伤病人手术前后的焦虑状态调查显示：术前状态焦虑量表评分显著高于术后；术前躯体性焦虑评分显著高于术后；高特质焦虑评分亚组与低特质焦虑评分亚组术前状态焦虑评分无显著差异，但术后则前者显著高于后者；急诊手术者手术前后状态焦虑评分显著高于择期手术者。     

Quantitative Whole Body Autoradiographic Disposition of Glycol Ether in Mice: Effect of Route of Administration

Glycol ethers such as ethylene glycol monomethyl ether (EGME)are common solvents used in many industrial products. A largenumber of individuals are exposed to EGME through differentexposure routes. We investigated the differential distributionof EGME following various routes of administration using wholebody autoradiographic (WBA) techniques. Male B6C3F1 mice weretreated with tracer iv or oral doses of [2-¹⁴C]EGME.(4.05 µgEGME/kg equivalent to 0.8 mCi/kg) and euthanized at 1 and 24hr following treatment. In both groups of animals the highestlevels of radioactivity were detected in the liver, urinarybladder, bone marrow, kidney, and epididymis, at 1- and 24-hrtime periods. Computer-assisted quantitation of WBA indicatedthat there was markedly higher deposition of [2-¹⁴ and/or itsmetabolites in various tissues of the orally treated animalsthan in animals treated intravenously. Our studies also suggestthat [2-¹⁴C]EGME is rapidly distributed either from blood orstomach to various tissues. Preferential deposition of radioactivityin the peripheral tissues of the bone, with a progressive inwardaccumulation in the bone marrow, was observed. Selective permeabilityof EGME and/or its metabolites was indicated by the higher uptakeby the epididymis than that by testis. The high levels of radioactivityin biosynthetically active tissues, e.g., the liver, bone marrow,and gastric mucosa, is an indication of persistent interactionof the compound with cellular components of these tissues. Theseinteractions may lead to EGME toxicity.     

Mucormycosis: A retrospective study

A retrospective study has been carried out in a hospital over the past 5 years on 13 patients of mucormycosis. The study included evaluating the etiology, pathology, clinical features, management, and complications of mucormycosis. The results and conclusions have been studied and summarised in our paper.

CT与磁共振成像在儿童人工耳蜗植入术前研究

目的　评价CT与磁共振成像 (magneticresonanceimaging ,MRI)在儿童人工耳蜗植入术前的诊断作用 ,以及对手术选择的影响。方法　 71例 ( 142耳 )双耳重度耳聋、拟行人工耳蜗植入的患儿进行术前CT与MRI检查。结果　CT与MRI均发现 ,12例 ( 2 2耳 )患者有前庭水管扩大 ( 15 5 % ) ;14例 ( 2 5耳 )患儿有Mondini畸形 ( 17 6% ) ;3例 ( 5耳 )患儿有内耳道扩大 ( 3 5 % ) ;2例 ( 4耳 )患者有可疑内耳道底骨质缺损 ( 2 8% )。MRI发现有 5例 ( 5耳 )患者单侧耳蜗纤维化 ( 3 5 % ) ,而CT未见异常。1例 ( 2耳 )患儿的CT显示面神经裸露 ( 1 4% ) ,MRI正常。结论　人工耳蜗植入术前应该进行CT与MRI检查。对于发现前庭水管综合征、Mondini畸形、内耳道扩张及内耳道底骨质缺损有重要意义。这二种影像学检查结果可以相互补充诊断耳蜗纤维化与面神经裸露。对手术适应证的选择以及保证手术正常进行有重要意义     

Pelvic malignant hemangiopericytoma mimicking an ovarian neoplasm; a case report

BACKGROUND: Malignant hemangiopericytoma (MHPC) is a rare vascular tumor and has been reported to occur in the musculature of the extremities, retroperitoneum and pelvis. Omental hemangiopericytomas (HPCs) are extremely rare. Synovial sarcomas and solitary fibrous tumors share histologic features with HPCs, causing diagnostic difficulties. Immunohistochemistry is essential for the diagnosis. CASE: A 74-year-old woman presented with an abdominopelvic mass. A malignant ovarian tumor was suspected on clinical features, ultrasound and computed tomography. Staging laparotomy revealed a large, vascular tumor adherent to loops of small bowel, colon, cecum and appendix, but the ovaries and uterus were normal. The tumor was completely removed after extensive dissection. Histopathology and detailed immunohistochemistry established the diagnosis of a malignant hemangiopericytoma arising from the omentum. The patient developed recurrent subacute bowel obstruction and died 4 months after the initial diagnosis. CONCLUSION: MHPCs are rare tumors and not likely to be diagnosed preoperatively. Treatment is therefore individualized and based on the findings at laparotomy. Some tumors, such as the one described here, exhibit very aggressive behavior.     

A multicentric study to evaluate efficacy and safety of cefetamet pivoxyl in lower respiratory tract infections in Indian patients

This multicentric, open label, non-comparative study was designed to evaluate the extended spectrum of third generation oral cephalosporin, cefetamet pivoxyl in the treatment of patients with lower respiratory tract infections. This study was conducted among 111 patients with clinical, radiological and bacteriological findings consistent with the diagnosis. After obtaining written informed consent, patients were given cefetamet 500 mg tablet twice a day for 7 days. Cefetamet consistently decreased all clinical signs and symptoms at post-therapy visit. All the treated patients were either cured or improved. Cefetamet was well tolerated with a low incidence of drug related adverse events. The findings of this study indicate that cefetamet pivoxyl was well tolerated and is suitable option for the treatment of patients with lower respiratory tract infection.
