2005年云南省克山病病情监测结果分析

目的为了全面掌握云南省克山病病情态势,科学指导和评价云南省克山病防制工作。方法按照《克山病监测》标准(W S/T78-1996)及《克山病诊断标准》(GB17021-1997)进行。监测内容包括临床检诊、心电图描记、可疑对象摄胸部后前位X线片。结果9个省级克山病监测点共检出克山病病例48例(1.03%),其中潜在型克山病(简称“潜克”)39例(0.84%),慢型克山病(简称“慢克”)9例(0.19%)。检出率与2004年相比,无显著性差异(χ2=1.362,P>0.05)。无急型克山病(简称“急克”)和亚急型克山病病例(简称“亚急克”)检出。全年累计新发慢克62例,发病率0.14/10万。结论目前云南省克山病病情处于平稳低发态势。克山病监测是了解克山病病情的一种科学手段,工作重点应放在病情监测、病情调查和对慢克病人的管理治疗,以及巩固和加强防治队伍建设等方面。

2005～2012年楚雄市克山病病情监测结果分析

目的掌握楚雄市克山病患病情况及发病趋势,为制定防治对策、措施提供依据。方法按《中央转移支付资金克山病病情调查项目云南省技术方案》的要求,在病区7个乡(镇)32个历史行政重病村中每年抽取1个自然村以上(调查点),2005~2012年共对15个自然村居民进行克山病病情调查:对调查点3~65岁常住居民进行体格检查,12导联心电图描记,对可疑克山病患者摄距2 m心脏x线后前位胸正位片,克山病人诊断按《克山病诊断标》(WS/T201-2011);收集、汇总2005~2012年8年克山病发病、死亡,病例搜索结果和克山病人现患情况,对克山病病情进行描述性分析和判断。结果 8年累计居民病情调查7174人,检出克山病人共44例,其中慢型占29.5%(13/44),潜在型占70.5%(31/44),3~14岁检出7例,占15.9%(7/44),年度检出率在0.2%~1.9%之间,平均检出率为0.6%(44/7174);年度克山病发病率在0.27/10万~2.91/10万之间,年平均为1.53/10万(44/2 873 064);8年累计登记克山病人123例,克山病人死亡64人,死亡率为52.0%;扩张型心肌病人中筛查出成人克山病人79人,均为慢型;2012年现患(现存)克山病人112人,最大年龄81岁,最小年龄9岁。结论克山病病人虽以潜在型为主,但3~14岁克山病人仍占病情调查总检出病人的近五分之一,2012年克山病发病率为2.71/10万(10/367 734),接近2005年的水平(2.91/10万),以及从扩张型心肌病人中搜索出的成人克山病人存在,表明楚雄市病情总体趋于平稳或略有回升,克山病致病因子(因素)还没有根本消除。

Objective To study the current incidence of Keshan disease in Yunnan Province,and provide scientific basis for Keshan disease(KD) prevention and control. Methods Based on the Scheme of KD Surveillance, 16 villages in 11 counties were chosen as surveillance sites by the historical data. An survey was made to the residents in the 16 surveillance sites by filling in the questionnaire, inquiry medical history, clinical examination, electrocardiogram and 2 meters post-anterior chest X-ray for suspected cases. KD cases were diagnosed according to the Diagnostic Criteria for Keshan Disease(GB 17021-1997). The prevalence data of KD in the whole province were collected from the KD case report in 2007 and the trace surveys. Results There were 6877 residents in 16 surveillance sites of 11 surveillance counties and totally 39 KD cases were diagnosed with a detection ratio of 0.57% (39/6877). The detection ratio of latent and chronic KD were 0.41%(28/6877) and 0.16%(11/6877), respectively and no acute or subacute cases were found. The cases aged 5 to 14 years old accounting for 66.67% (26/39). Electrocardiogram examination of 6877 residents were made and 5.25% (361/6877) abnormal electrocardiograms were detected in the 16 surveillance sites. Fifty-five people were checked by chest X-ray and there were 31 cases with heart-chest ratio ≤0.50, 16 cases with heart-chest ratio from 0.51 to 0.55 and 8 cases with heart-chest ratio from 0.56 to 0.60. The prevalence rate and incidence rate of chronic KD were 4.24 per 100 000 and 0.50 per 100 000 in Yunnan. No acute or subacute cases were found and the latent cases were listed. The prevalence rate and incidence rate were 7.76 per 100 000 and 1.18 per 100 000 in the 16 surveillance sites. Conclusions The incidence of KD is low incidence in Yunnan Province. Higher ineidence of chronic KD was detected in the some areas and the corresponding control measures need to be adopted.

Objective To study the current incidence of Keshan disease in Yunnan Province,and provide scientific basis for Keshan disease(KD) prevention and control. Methods Based on the Scheme of KD Surveillance, 16 villages in 11 counties were chosen as surveillance sites by the historical data. An survey was made to the residents in the 16 surveillance sites by filling in the questionnaire, inquiry medical history, clinical examination, electrocardiogram and 2 meters post-anterior chest X-ray for suspected cases. KD cases were diagnosed according to the Diagnostic Criteria for Keshan Disease(GB 17021-1997). The prevalence data of KD in the whole province were collected from the KD case report in 2007 and the trace surveys. Results There were 6877 residents in 16 surveillance sites of 11 surveillance counties and totally 39 KD cases were diagnosed with a detection ratio of 0.57% (39/6877). The detection ratio of latent and chronic KD were 0.41%(28/6877) and 0.16%(11/6877), respectively and no acute or subacute cases were found. The cases aged 5 to 14 years old accounting for 66.67% (26/39). Electrocardiogram examination of 6877 residents were made and 5.25% (361/6877) abnormal electrocardiograms were detected in the 16 surveillance sites. Fifty-five people were checked by chest X-ray and there were 31 cases with heart-chest ratio ≤0.50, 16 cases with heart-chest ratio from 0.51 to 0.55 and 8 cases with heart-chest ratio from 0.56 to 0.60. The prevalence rate and incidence rate of chronic KD were 4.24 per 100 000 and 0.50 per 100 000 in Yunnan. No acute or subacute cases were found and the latent cases were listed. The prevalence rate and incidence rate were 7.76 per 100 000 and 1.18 per 100 000 in the 16 surveillance sites. Conclusions The incidence of KD is low incidence in Yunnan Province. Higher ineidence of chronic KD was detected in the some areas and the corresponding control measures need to be adopted.     

1997年山西省克山病监测结果分析

2005年四川省克山病监测结果分析

目的了解四川省克山病病情现状。方法根据《2004年国家地方病防治项目克山病监测技术方案》要求,对监测点区居民进行询问并记录克山病病史,听、叩诊心、肝、肾,测量血压,描记12导联心电图,对克山病病人及可疑病例拍摄心脏正位X线片。观察急型、亚急型、自然慢型、潜在型克山病检出率及转归情况。用荧光法测定人群发硒、环境水硒、粮食中硒,并调查病区人群经济水平和日常生活膳食结构。结果克山病临床检诊率93．1％,各型克山病临床总检出率2．23％;重点人群(3-14岁儿童)检出率1．50％,非重点人群(15- 70岁成人)检出率3．47％;心电图检查的异常率13．5％;儿童发硒(0．3669±0．0990)mg／kg,粮食硒(0．0105±0．0066)mg／kg,水硒均值<0．25μg／L。结论目前四川省仍有亚急型、慢型克山病新发,儿童潜在型克山病检出率相对较高。     

2011年蛟河市克山病监测结果分析

吉林市所辖县（市）区均为克山病病区,10余年来均无急型和亚急型克山病发生,但自然慢型和潜在型病人经常被检出,为掌握克山病的增长趋势,我市按照《全国克山病监测方案（试行）》的内容和要求,于2010～2011年分别开展了克山病的监测工作,现将监测结果报告如下。
