Epidemiological studies on tinea pedis and onychomycosis, common fungal infections, have been conducted in many parts of the world. There are currently no studies of tinea pedis and/or onychomycosis in Algeria. The aim of this paper was to study the epidemiology of foot diseases, including tinea pedis and onychomycosis and to identify the aetiological factors of these infections in outpatients attending the Department of Dermatology of the Central Hospital of Army in Algiers, Algeria. A total of 1300 male subjects, mean age 35.9 +/- 16 years (range: 16-80) were recruited during the period November 2003 to November 2004 and were clinically examined. A complete dermatological examination was performed on all subjects, and skin and nail specimens of the feet were taken from those patients presenting signs of tinea pedis and/or onychomycosis for microscopy and fungal culture. Clinical diagnosis for tinea pedis and onychomycosis was suspected in 249 and 72 subjects, respectively, and confirmed in 197 and 60 cases, respectively, by positive cultures, resulting in a global prevalence of tinea pedis and toenail onychomycosis of 15% and 4.6% respectively. The age groups most commonly infected were 50-59 and 20-29 years. The yeast species Candida parapsilosis and the dermatophytic species Trichophyton rubrum were shown to be the most common pathogens in both tinea pedis (C. parapsilosis 20.4%; T. rubrum 17%) and onychomycosis (T. rubrum 35%; C. parapsilosis 28.3%). This is the first investigation dealing with fungal foot diseases in Algeria. The clinical and epidemiological data collected would serve as reference for future research and may be useful in the development of preventive and educational strategies.
There have been few studies on fungal infection of the foot in military personnel. The aim of this study was to determine the prevalence and aetiological factors of superficial mycoses of the foot in military personnel attending the Department of Dermatology of the Army Central Hospital in Algiers, Algeria. A complete dermatological examination was performed in 650 male military personnel. Cultures of skin and nail specimens of the feet were performed for each participant. Fungal infection of the foot (including tinea pedis and Candida interdigital infection) was clinically diagnosed in 147, and confirmed in 119 by positive cultures, resulting in a total prevalence of 18.3%. When subjects were grouped according to military rank, fungal infection of the foot was prevalent in troop soldiers; when grouped according to years of service to the army, the infection was frequent in military recruits. The dermatophyte species Trichophyton rubrum (20.9%) and the yeast species Candida parapsilosis (18.7%) were shown to be the major causal agents isolated. Tinea pedis and Candida interdigital infection are the most prevalent (68%) superficial fungal infections among Algerian military personnel.
