Ringworm/Dermatophytosis/Tinea Infections
Published in Charles Theisler, Adjuvant Medical Care, 2023
Ringworm, also known as dermatophytosis, is not a worm but a fungal (tinea) infection of the skin. The fungi live on the dead tissues of the skin, hair, and nails. Tinea infections are commonly referred to as ringworm due to the characteristic circular lesions. These infections are named for the affected body part, such as tinea pedis (feet), tinea capitis (scalp), and tinea corporis (body). Typically, it results in a circular red, itchy, scaly rash. Ringworm occurs in people of all ages, but it is particularly common in children. It occurs most often in warm, moist climates. Ringworm is a contagious disease and can be passed from person to person by contact with infected skin areas or by sharing combs and brushes, other personal care items, or clothing.'
Therapeutic effectiveness

Dermatophytosis is a superficial fungal infection of keratinized tissue. The infection is commonly known as tinea. The fungal growth rate must either equal or exceed the epidermal turnover rate, as otherwise the organism will be shade quickly. The infection spontaneously resolves. If a second infection by the same organism is produced, the site becomes inflamed very early and resolves relatively quickly (Kanwar & De, 2008, pp. 252–254). Warts are benign proliferation of the skin resulting from infection with human papillomavirus. Warts occur at any age. Most cutaneous warts are self-limiting and spontaneously regress within two years of onset. About 65% of common warts disappear spontaneously within two years. The regression is earlier in male children. Regression of common warts is asymptomatic and occurs gradually over several weeks usually without any sequelae (Criton, 2008, pp. 366–370).

Topical therapy may be sufficient for dermatophytosis other than nail and scalp infections—for example, terbinafine topical formulations, tolnaftate, imidazole, amorolfine, cyclopiroxolamine, clotrimazole, miconazole, econazole, ketoconazole, bifonazole and tioconazole. Terbinafine, which has the shortest treatment time of topical antifungals, takes about one week to kill the fungus but the skin will take about 2–4 weeks to return to normal.

We assessed the NAMCS for all visits where international classification of disease ninth-modification (ICD-9) codes 110.0, 110.1, 110.3, 110.4, 110.5, 112.9, 112.3, 111.0 and ICD-10 codes B35.0, B35.1, B35.4, B35.4, B35.6, B37.9, B37.2, and B36.0 were a primary through quinary diagnosis. These represent “dermatophytosis of scalp and beard,” “dermatophytosis of nail,” “dermatophytosis of groin and perianal area,” “dermatophytosis of foot,” “dermatophytosis of the body,” “candidiasis of unspecified site,” “candidiasis of skin and nails,” and “pityriasis versicolor.” We performed the analysis using the survey procedures of SAS University Edition (SAS Institute Inc., Cary, NC, USA.). To adjust for the multiple hypothesis tests performed, we adjusted the standard alpha value of .05 to .01 by the Bonferroni correction (7).

The age range of visit that most frequently presented with nail complaints was 45–64 (6.2 [5.1–7.3] million visits), followed by 25–44 (5.7 [4.5–6.9] million visits) (Figure 1). The other age groups had fewer visits involving nail complaints and nail diagnoses. The diagnoses with the most variable age group differences were paronychia of toe, paronychia of finger, and dermatophytosis of nail (Figure 2). Paronychia of toe was most commonly diagnosed in the age ranges 0–14 (424 [153–696] thousand visits) and 15–24 (464 [117–811] thousand visits). Paronychia of finger was most commonly diagnosed in the age ranges 0–14 (371 [95.7–647] thousand visits) and 45–64 (323 [116–531] thousand visits). Dermatophytosis of nail was primarily diagnosed in ages 25–44 (3.42 [2.49–4.35] million visits) and 45–64 (3.47 [2.65–4.29] million visits).

Dermatophytes are filamentous fungi belonging to the genera Microsporum, Trichophyton and Epidermophyton, which use keratin as their main nutritional source (Segal and Frenkel 2015; Moriello et al. 2017). Dermatophytosis is the name of the infection caused by these fungi and is the most frequent dermatomycosis in animals. A prevalence of 49.7% has been reported in animals with fungal infections (Shokri and Khosravi 2016). Previous studies indicate that M. canis, M. gypseum and T. mentagrophytes are the most commonly isolated species, accounting for 95% of the cases of dermatophytosis in companion animals (Mattei et al. 2014; Shokri and Khosravi 2016). There is no sexual predilection for the occurrence of dermatophytosis, but higher incidence is observed in young and old animals. As for the breed, higher prevalence and more severe lesions have been observed in Yorkshire Terrier dogs and Persian cats. In these breeds, cases of dermatophytosis presented as subcutaneous infections or pseudomycetomas have been reported (Moriello et al. 2017).
