Trichophyton onychocola is a recently described geophilic dermatophyte that has been isolated from a toenail of Czech patient with a history of onychomycosis due to T. rubrum and clinical suspicion of relapse. In this study, we report a similar case from Denmark in an otherwise healthy 56-year-old man. The patient had a history of great toenail infection caused by T. rubrum in 2004 and presented with suspected relapse in 2011 and 2013. Trichophyton onychocola was the only microbial agent isolated at the second visit in 2013 and the identification was confirmed by DNA sequencing...

Onychomycosis is a common disease seen in dermatology practice. Most patients with onychomycosis opt for treatment due to the social stigma attached to the unsightly appearance, as well as the pain that can at times make walking difficult. However, in many cases, onychomycosis is resistant to oral antifungal medication, which is the first-line therapy for this disease. In recent years, we have attempted a new treatment method using a long-pulsed 1,064nm Nd :YAG laser (Cutera Inc., Brisbane, CA, USA) in refractory cases with onychomycosis...

Onychomycosis is a fungal infection of the nail unit, more common in toenails than in fingernails, and caused by a variety of fungi including dermatophytes, nondermatophyte molds, and <em>Candida.</em> There are 4 to 5 subtypes related to the method of fungal invasion of the nail unit, the most common being distal lateral subungual onychomycosis. Here the fungus enters the distal lateral part of the nail bed, the region of the hyponychium, often as an extension of tinea pedis. Hyperkeratosis occurs under the nail plate, resulting in detachment of the nail plate from the nail bed (onycholysis), with subungual thickening...

Onychomycosis is usually caused by dermatophytes, but some nondermatophytic molds and yeasts are also associated with invasion of nails. The genus Chaetomium is a dematiaceous nondermatophytic mold found in soil and plant debris as a saprophytic fungus. We report the first Korean case of onychomycosis caused by Chaetomium globosum in a 35-year-old male. The patient showed brownish-yellow discoloration and subungual hyperkeratosis on the right toenails (1st and 5th) and left toenails (1st and 4th). Direct microscopic examination of scraping on the potassium hydroxide preparation revealed septate hyphae and repeated cultures on Sabouraud's dextrose agar (SDA) without cycloheximide slants showed the same fast-growing colonies, which were initially velvety white then turned to dark gray to brown...

Onychomycosis is one of the most frequent infections affecting the fingernails or the toenails and it is caused mainly by dermatophytes. The aim of the study was to assess the frequency of onychomycoses in hemodialysis patients and to relate sex, age, duration of hemodialysis and causes of renal failure to the development of nail disorders. The study included 100 patients with chronic renal failure undergoing hemodialysis. The patients underwent detailed clinical examination of the toenails and those with any kind of clinical finding had nail scraping for mycological testing...

The study objective was to evaluate the safety, tolerability, systemic exposure, and pharmacokinetics (PK) of 10% luliconazole solution (luliconazole) when topically applied once daily to all 10 toenails and periungual areas in patients with moderate to severe distal subungual onychomycosis. In this single-center, open-label study, 24 patients applied 20 mg/ml of luliconazole (twice the clinical dose) for 29 days with a 7-day follow-up. Complete PK profiles were determined on days 1, 8, 15, and 29. Safety/tolerability assessments included application site reactions, adverse events, vital signs, clinical laboratory findings, and electrocardiograms...

Onychomyosis caused by Aspergillus sydowii is rare and difficult to diagnose. We report a case in which this disease was diagnosed by molecular-biological methods. The patient was a 53-year-old woman without any notable past history. She visited our hospital complaining of itching around the right first toenail in June 2010, although she had noticed nail opacification for 4 years. Opaque thickening of the nail, covering 57.3% of the normal nail area, was observed. Direct microscopic examination revealed thick mycelia with septa and black spores...

The aim of this investigation was to resolve a diagnostic problem and report toenail unit changes attributable to shoe friction that resemble onychomycosis, but that are fungus-negative, and identify common skeletal causes in patients with an asymmetric walking gait. X-ray and clinical feet inspections were performed to evaluate skeletal components that change normal foot biodynamics. Forty-nine patients, all dermatophyte-negative, were reviewed. All patients were those seen in our private practice who demonstrated skeletal and toenail unit abnormalities such as onycholysis, nail bed keratosis resembling distal subungual onychomycosis, nail plate surface abnormalities, distal toe skin keratosis, a diagnostic nail plate shape, as well as several skeletal abnormalities...
