RESUMO
An investigative study was performed to determine the diagnosis of onychomycosis in a South Florida geriatric population. In this study, 450 cases of suspected onychomycosis involving men and women 65 years of age and older from a private practice office and two nursing home settings were used. Samples were taken from the hallux toenail and sent to a mycology laboratory for fluorescent potassium hydroxide (KOH) preparation and microscopic examination of a fungal culture. Of the 450 cases studied, 46.4% of the patients had a single fungal organism cultured, 30.4% had a mixed fungal infection cultured, and 23.1% had no fungal growth. Saprophytes were found in 59.9% of the 526 total fungal organisms cultured while dermatophytes were found in only 23.8%. The results of this investigation demonstrate that there may be a shift from isolated dermatophyte infection to mixed saprophyte infections in a geriatric population with onychomycosis.

Onychomycosis is the most frequently encountered condition in podiatric practice in the United States. A variety of modalities are available to confirm the presumptive diagnosis of onychomycosis. This study was conducted to compare the results of in-office dermatophyte test medium cultures with those of mycology laboratory analysis for 100 cases of suspected onychomycosis in a geriatric population. The results demonstrated that 20% of the patients had dermatophyte involvement, 56% had saprophyte involvement, and 19% had yeast involvement. Only 50% of positive dermatophyte test medium cultures correlated with a positive microscopic fungal culture for dermatophytes. Given these results, it is questionable whether in-office dermatophyte test medium cultures should be routinely used in geriatric patients for the diagnosis of onychomycosis. The authors believe mycology laboratory testing with fluorescent potassium hydroxide preparations and microscopic fungal cultures to be superior to in-office dermatophyte test medium cultures for the diagnosis of onychomycosis in geriatric patients.

Three cases of intraosseous ganglion cysts of the ankle are presented with an average follow-up of 68 months (range, 48-78 months). Review of the literature revealed 251 cases of intraosseous ganglion cysts, with 75 located in the ankle and a recurrence rate of 6.1%. In the three cases presented, a satisfactory long-term result was obtained with bone graft and curettage in two cases and currettage alone in one case. No recurrences or complications occurred.
