BACKGROUND: Tinea pedis and onychomycosis are among the commonest fungal diseases in the world. Dermatophytes and, less frequently, non-dermatophyte molds are etiological agents of foot mycosis and could be able to form biofilms. Fungal biofilm has demonstrated increasing drug resistance OBJECTIVES: This work aims to evaluate in vitro the ability to form biofilm and the susceptibility to antifungal drugs of sessile dermatophytes and non-dermatophyte molds involved in foot mycosis. Methods Thirty-six dermatophytes and non-dermatophyte molds isolated from Tunisian patients with foot mycoses, and identified with MALDI-TOF have been tested...

The study evaluated the newly formatted Aspergillus-specific lateral-flow-device (LFD), and compared its performance to the original prototype "old" LFD test using BALF samples from 28 patients (14 patients with probable/proven invasive pulmonary aspergillosis [IPA] and 14 patients with no evidence for IPA). A total of 10/14 (71%) of BALF samples from patients with probable/proven IPA resulted positive with the new LFD, including 8/9 with true-positive and 2/5 with false-negative results with the old LFD. All 14 samples from patients without IPA resulted negative with the new LFD; specificity of the new LFD was significantly improved compared to the old LFD...

BACKGROUND: Fungal rhinosinusitis has a worldwide distribution, comprises distinct clinical entities but is mostly due to Aspergillus among which A. fumigatus plays a major role in European countries. Although, there is accumulating evidence for the emergence of environmentally acquired-azole resistance in A. fumigatus (such as TR34 /L98H) in various clinical settings, there is few data for patients with fungal rhinosinusitis. OBJECTIVES: To investigate the prevalence of A...

The diagnosis of invasive pulmonary aspergillosis (IPA) increasingly relies on non-culture-based biomarkers in bronchoalveolar lavage (BAL) fluid. The Aspergillus lateral flow device (LFD) is a rapid immunoassay that uses a novel Aspergillus monoclonal antibody to gain specificity. The objective of the study is to compare specificity and sensitivity of the prototype LFD and the galactomannan (GM) enzyme immunoassay in BAL fluid in high-risk patients. A total of 114 BAL samples from 106 patients at high risk for IPA were studied: 8 patients had proven/probable IPA, 16 had possible IPA and 82 did not have IPA...

Mucormycosis is an aggressive and life-threatening opportunistic fungal infection, which predominantly affects immunocompromised patients. It typically manifests in rhinocerebral, pulmonary or disseminated forms in patients with immunosuppressive conditions. Mucormycosis limited to the oral cavity is rare, and to the best of our knowledge only seven cases have previously been reported in English literature. We present five consecutive cases of oral mucormycosis in patients with leukaemia, and provide a literature review...

Nail psoriasis and onychomycosis can often be hard to differentiate clinically and may coexist, complicating each other's course. The aim of this study was to determine the prevalence of onychomycosis among patients with nail psoriasis not being treated with immunosuppressive agents, which constitute an independent risk factor for fungal infections. A cross-sectional study was performed. All adult patients with nail psoriasis who were not receiving antifungal and/or immunosuppressive treatment were recruited at the 2nd University Dermatology Department of Aristotle University of Thessaloniki from 10/2016 till 02/2017...
