The pathophysiological mechanism of fluid retention in advanced cancer patients treated with docetaxel, but not receiving corticosteroid comedication

Aims Fluid retention is a phenomenon associated with taxoids. The principal objective of this study was to investigate the pathophysiological mechanism of docetaxel-induced fluid retention in advanced cancer patients

Concordance between direct microscopy and fungical culture for the diagnostic of feet's onychomycosis Concordância entre o exame micológico direto e a cultura para fungos no diagnóstico das onicomicoses dos pés

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.<br>Estudo prospectivo avaliando a concordância entre os resultados do exame micológico direto e dacultura para fungos de material coletado de pacientes com suspeita clínica de onicomicose dos pés. Ocorreu concordância em 56,1% dos exames com dermatófitos, em 52,4% dos exames com outros fungos e em 90,4% dos exames negativos (0,54 de acordo com o teste kappa). Em 39,3% das onicomicoses por dermatófitos e em 31,8% das por não dermatófitos, os agentes etiológicos foram identificados somente pelo exame direto. O exame direto demonstrou maior sensibilidade, comparado ao cultural, sendo superior em 19,5% da amostra total e mantendo concordância com a cultura em 71,5% da amostra
