临床表现诊断饮水型氟骨症价值评析

目的 比较饮水型地方性氟骨症临床表现诊断与X线诊断的差异,评价临床表现对该病的诊断价值,为按照临床表现对该病进行早期诊断提供理论依据.方法 调查244例高氟病区居民的临床症状和体征,统计各种症状、体征检出率,并依据临床表现进行诊断与分度;拍摄骨关节X线照片,按照WS192-1999标准进行X线诊断与分度;比较临床与X线方法诊断及分度结果的差异;计算临床诊断方法的真实性、可靠性等指标,并根据上述指标对其诊断价值进行评价.结果 饮水型地方性氟骨症最常见的临床表现为骨关节的疼痛和僵硬;临床和X线方法检出率分别为69.3%和63.1%,两种方法诊断结果的差异没有统计б庖?P>0.05);临床与X线诊断方法的符合率为69.3%;二者在分度上表现出交叉;临床诊断方法灵敏度为80.5%,特异度为50.0%,假阴性率为19.5%,假阳性率为50.0%;ROC曲线下面积为0.653.结论 临床与X线诊断方法对氟骨症的检出率相同.依据临床表现对该病进行诊断的特异度不高,可能由于临床表现为非客观性指标,不好控制;临床表现诊断法误诊率较高;临床诊断与X线诊断方法对该病的诊断结果较一致,虽不可单独诊断,却可为确诊该病提供重要线索.
