Abstract

Prospective study compared the agreement between the direct microscopy and fungical culture from subungueal samples of the patients with clinical suspicion of feet's onychomycosis. The agreement occurred in 56.1% of the exams with dermatophytes, in 52.4% by others fungi and in 90.4% of the negative cases, 0,54 according to the Kappa`s test. In 39.3% of the onychomycosis caused by dermatophytes and 31.8% by nondermatophytes, these were identificated only for direct microscopy. The direct microscopic showed more sensibility compared with the culture, being superior in 19.5% of the total sample and maintaining agreement with the culture in 71.5% of the sample.

摘要

前瞻性研究比较了临床怀疑足部甲真菌病患者甲下样本直接显微镜检查与真菌培养结果的一致性。皮肤癣菌检查中56.1%结果一致，其他真菌检查中52.4%结果一致，阴性病例中90.4%结果一致，根据卡帕检验为0.54。在由皮肤癣菌引起的甲真菌病中，39.3%仅通过直接显微镜检查得以鉴定，非皮肤癣菌引起的甲真菌病中这一比例为31.8%。与培养相比，直接显微镜检查显示出更高的敏感性，在总样本中高出19.5%，在71.5%的样本中与培养结果一致。
