目的:通过对深圳市某两所小学发生的流行性腮腺炎突发疫情的流行病学特点及差异性进行分析,为制定科学、高效的防控策略提供科学依据。方法2013年5~7月深圳市大鹏新区某两所小学爆发流行性腮腺炎,以学校为整体研究对象,分别标记为学校A(24个班,学生1210例)和学校B(27个班,学生1274例),对比两所小学的疫情流行病学差异性。结果分析发现,学校A流行性腮腺炎发病率为4.30%,发病班级所占比54.17%,均较学校B1.73%和29.63%高,对比差异有统计学意义(P<0.05);分析显示学校A学生出现疫病平均年龄为(11.2±1.1)岁,较学校B(9.34±1.0)岁,对比差异明显(P<0.05);且两组疫病患儿在接种疫苗率对比上差异无统计学意义(P>0.05);但疫情发生时,学校B疫苗紧急接种率明显高于学校A,对比差异有统计学意义(P<0.05)。结论小学作为流行性腮腺炎爆发的主要场所之一,疫病爆发高峰季节前,针对易感染人群给予相应的疫苗接种等预防控制措施,同时加强流行性腮腺炎的监测,对于降低感染人群数量,减轻、遏制疫情有着积极的意义,值得相关防控部门重视。  相似文献

Pathogenesis of carcinoma of the papilla of Vater   总被引:6,自引:0,他引:6  
Most adenomas and carcinomas of the small intestine and extrahepatic bile ducts arise in the region of the papilla of Vater. In familial adenomatous polyposis (FAP) it is the main location for carcinomas after proctocolectomy. In many cases symptoms due to stenosis lead to diagnosis at an early tumor stage. In about 80%, curative intended resection is possible. Operability is the most relevant prognostic factor. Most ampullary carcinomas resp. carcinomas of the papilla of Vater develop from adenomatous or flat dysplastic precursor lesions. They can be sited in the ampulloduodenal part of the papilla of Vater, which is lined by intestinal mucosa. They also can develop in deeper parts of the ampulla, which are lined by pancreaticobiliary duct mucosa. Intestinal-type adenocarcinoma and pancreaticobiliary-type adenocarcinoma represent the main histological types of ampullary carcinoma. Furthermore, there exist unusual types and undifferentiated carcinomas. Many carcinomas of intestinal type express the immunohistochemical marker profile of intestinal mucosa (keratin 7–, keratin 20+, MUC2+). Carcinomas of pancreaticobiliary type usually show the immunohistochemical profile of pancreaticobiliary duct mucosa (keratin 7+, keratin 20–, MUC2–). Even poorly differentiated carcinomas, as well as unusual histological types, may conserve the marker profile of the mucosa they developed from. These findings underline the concept of histogenetically different carcinomas of the papilla of Vater which develop either from intestinal- or from pancreaticobiliary-type mucosa of the papilla of Vater. Molecular alterations in ampullary carcinomas are similar to those of colorectal as well as pancreatic carcinomas, although they appear at different frequencies. In future studies, molecular alterations in ampullary carcinomas should be correlated closely with the different histologic tumor types. Consequently, the histologic classification should reflect the histogenesis of ampullary tumors from the two different types of papillary mucosa.  相似文献

Summary A survey of all members of the Swiss Medical Association of Manual Medicine was undertaken for the year 1989. Informative data were given by 425 respondents on the frequency of complications of manipulation as related to the spine. The number of thoraco-lumbar manipulations during 1989 (225 working days) was 805 for each respondent, and the number manipulations of the cervical spine 354. Thus, the total number of thoraco-lumbar manipulations was 342 125, and the total number of cervical manipulations was 150 450. The overall incidence of side-effects of transient complications due to cervical spine manipulation such as disturbance of consciousness or radicular signs was 1: 16716. Seventeen patients (ratio 1: 20 125) after manipulation of the lumbar spine presented, in addition to increased pain, a transient sensorimotor deficit with precise radicular distribution. Nine of the 17 patients (ratio 1: 38013) developed a progressive radicular syndrome with sensorimotor defict and radiologically verified disc herniation and had to be referred for surgery. Side effects and complications of cervical and lumbar spine manipulation are rare. Taking in to account the yearly number of manipulations performed by a single physician in Switzerland and the rate of complications, it can be calculated that a physician practicing manual medicine will encoutner one complication due to manipulation of the cervical spine in 47 years and one complication due to lumbar spine manipulation in 38 years of practice. However, it is important that a careful clinical assessment is carried out to avoid complications due to manipulation carried out on the basis of inappropriate indications. Furthermore, the decision as to which technique is indicated for any particular functional disorder of the spine should be made on the basis of rational criteria resting on a knowledge of clinical biomechanics, functional anatomy and neurophysiology. The authors recommend a prospective morbidity study to be carried out among physicians, chiropractors, osteopaths and physiotherapists, taking into account the different indications and therapeutic techniques in relation to complications.  相似文献

目的:探讨接受外科治疗的胰头癌患者的临床病理特点。方法:回顾性将根治性切除与姑息性切除手术病例进行对照,对其年龄、性别、症状、体征、围手术期情况、肿瘤标记物检查、临床病理、手术并发症、手术切除率、生存率及其影响因素进行分析。结果:63例中,52例(91.2%)获得随访,根治组中位生存时间(13.8个月)明显高于姑息组(6.2个月)(P0.05),姑息组(6.2个月)与非手术组(5.4个月)无明显差异(P0.05);根治组患者导管腺癌发生率与姑息组比较有显著差异(P0.05);T1期患者切除率高于T4期(P0.01),CA19-9数值与胰头癌可切除率无明显相关(P0.05)。结论:手术是提高胰头癌患者生存率的重要手段,具有不同临床分期的胰头癌病人手术切除率及术后生存期具有显著差异。CA19-9可作为胰头癌常规的筛查方法,但与疾病进展程度无关。  相似文献
