SOUZA, Paulo Ricardo Martins et al. Concordance between direct microscopy and fungical culture for the diagnostic of feet's onychomycosis. An. Bras. Dermatol. [online]. 2012, vol.87, n.1, pp.157-159. ISSN 1806-4841. http://dx.doi.org/10.1590/S0365-05962012000100028.
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.
