Background. There are relatively few studies published examining the sensitivity and specificity of potassium hydroxide (KOH) smear and fungal culture examination of tinea pedis. Objective. To evaluate the sensitivity and specificity of KOH smear and fungal culture for diagnosing tinea pedis.
BACKGROUND
Traditional diagnostic testing for dermatophyte infection currently requires skin scraping for light microscopy and/or fungal culture or skin biopsy. Immunofluorescent microscopy can also be used with calcofluor stain. All of these tests can be time-consuming to perform, require a waiting
In this study, we investigated the role of successive potassium hydroxide (KOH) tests for the diagnosis of tinea pedis with different clinical presentations. The study included 135 patients with 200 lesions that were clinically suspicious for tinea pedis. Three samples of skin scrapings were taken
BACKGROUND
The diagnosis of tinea versicolor can usually be made by clinical examination. Either potassium hydroxide (KOH) or Wood's light fluorescence are used to corroborate the diagnosis. Albert's solution has been reported as a method of visualizing dermatophytes. We compared Albert's solution
The current upsurge of complicated dermatophytosis in India and other parts of the world has necessitated the development of rapid and accurate diagnostic techniques. Conventional methods such as potassium hydroxide (KOH) mount lack color contrast and require a trained eye, whereas BACKGROUND
Microscopy of a potassium hydroxide preparation of skin scrapings or nail clippings, although widely advocated as a test for dermatomycosis, is used in only a small proportion of cases.
OBJECTIVE
This study set out to investigate the effect of potassium hydroxide testing on the
BACKGROUND
The diagnosis of superficial mycosis such as dermatophytosis is often done clinically. However, in difficult cases, a rapid test with high sensitivity and specificity helps in the immediate confirmation and administration of treatment.
METHODS
The efficacy, rapidity of detection, and
Dermatophytes are fungi that cause infections affecting hair, nail, and skin; in nails they cause onychomycosis, while in hair they lead to tinea capitis. Detection of dermatophytes using traditional methods, including potassium hydroxide (KOH) and culture on agar-based media leads to Dermatophytosis is a superficial fungal infection of keratinized tissues. Dermatophytes can cause discomfort but are not usually life threatening. However, the infection can spread and may lead to systemic fungal infections in immunocompromised patients. Currently available diagnostic methods
