| scytalidium and scytalidiosis: what's new in 2012? | fungi belonging to the genus scytalidium are widespread around the world. among them, two species are responsible for human superficial infections mimicking dermatophytosis: neoscytalidium dimidiatum and scytalidium hyalinum. whereas these ascomycetous fungi are endemic in tropical or subtropical countries, both species have a different geographical distribution. scytalidiosis represents approximately 40% of dermatomycoses in these areas. a few cases of invasive infections due to scytalidium sp. ... | 2013 | 23416171 |
| onychomycosis in cameroon: a clinical and epidemiological study among dermatological patients. | there are currently no studies on epidemiology and clinical aspects of nail fungal infections in the general population of cameroon. | 2012 | 23171013 |
| successful identification of clinical dermatophyte and neoscytalidium species by matrix-assisted laser desorption ionization-time of flight mass spectrometry. | dermatophytes are keratinolytic fungi responsible for a wide variety of diseases of glabrous skin, nails, and hair. their identification, currently based on morphological criteria, is hindered by intraspecies morphological variability and the atypical morphology of some clinical isolates. the aim of this study was to evaluate matrix-assisted laser desorption ionization-time of flight mass spectrometry (maldi-tof ms) as a routine tool for identifying dermatophyte and neoscytalidium species, both ... | 2012 | 22535981 |
| [subcutaneous infection spread by scytalidium (neoscytalidium) dimidiatum]. | s. dimidiatum (recently reclassified as n. dimidiatum) is a fungus that causes nail and/or superficial skin infection. it may also cause subcutaneous and deep infection, chiefly in immunocompromised patients. | 2012 | 22401686 |
| successful eradication of scytalidium dimidiatum-induced ungual and cutaneous infection with voriconazole. | we report the successful treatment of extensive cutaneous infection and onychomycosis caused by scytalidium dimidiatum in a 30-year old nigerian woman. | 2014 | 22377678 |
| in vitro antifungal susceptibility of neoscytalidium dimidiatum clinical isolates from malaysia. | neoscytalidium dimidiatum is an opportunistic fungus causing cutaneous infections mostly, which are difficult to treat due to antifungal resistance. in malaysia, n. dimidiatum is associated with skin and nail infections, especially in the elderly. these infections may be mistaken for dermatophyte infections due to similar clinical appearance. in this study, neoscytalidium isolates from cutaneous specimens, identified using morphological and molecular methods (28 neoscytalidium dimidiatum and 1 n ... | 2017 | 27815659 |
| cutaneous murine model of infection caused by neoscytalidium dimidiatum: a preliminary study of an emerging human pathogen. | neoscytalidium dimidiatum is an emerging fungus that causes a skin infection similar to dermatophytosis; it affects both immunocompetent and immunosuppressed individuals, and it may invade deeper tissues and organs and cause systemic disease. little is known about the etiopathogenesis of the infection caused by this fungus, and no standard effective treatment is available. the aim of the present experimental study was to develop an animal model of skin infection with n. dimidiatum. balb/c mice w ... | 2016 | 27250925 |
| efficacy of 5% amorolfine nail lacquer in neoscytalidium dimidiatum onychomycosis. | amorolfine nail lacquer was mentioned as an effective treatment for non-dermatophyte nail infection. onychomycosis that caused by neoscytalidium dimidiatum is considered recalcitrant onychomycosis. | 2016 | 26471716 |
| pulmonary fungal infection caused by neoscytalidium dimidiatum. | neoscytalidium dimidiatum is a mold known to cause onychomycosis and dermatomycosis; however, it is an extremely rare cause of systemic infection. we report a case of pulmonary infection with neoscytalidium dimidiatum in an immunocompromised patient and discuss in vitro susceptibility data from this case and previous literature. | 2015 | 25948605 |
