“…Our results showed that 6.1% of patients had onyxis of both hands and feet. Our findings are similar to previous reports 1,3,16 . With respect to age, onyxis was shown to mainly occur in 20–50 years old women and 40–50 years old men.…”

“…On the other hand, fingers’ onyxis was more frequent in women than men (85.4% vs. 77.5%), whereas no gender predominance was shown in toes’ onyxis (74.8% vs. 73.7%). In this respect, our results are similar to many previous studies 6,12–14 ; in other studies, however, a female predominance was reported for all localisations 1,3,15 . The higher proportion of hand onyxis in women may again be attributed to the aesthetic factors because the damage is more obvious in hands as compared with feet, so that the frequency of feet onyxis looks similar in both sexes.…”

“…So that, the culture must systematically be associated. However, culture itself may be negative despite a positive direct examination as shown in 5.5% of our patients and as already mentioned in many previous studies 1,3,5,11 …”

“…The high frequency of this pathology in adults was highlighted in many previous studies where in some regions, the prevalence of fungal onyxis reaches 50% 3–8 . Previous Tunisian studies are in accordance with these findings 1,9 . Such high frequency mainly in women can be attributed to domestic chores, humidity, the use of detergents and alkalis, diabetes, the lack of hygiene and etc.…”

“…On the other hand, the female predominance mentioned above could be demonstrated whatever the age of the patient. The scarcity of onychomycosis in children included in our study has already been reported 1,6,9,13,15,18 . In infants <1 year, onyxis are mainly caused by C. albicans , dermatophytes being exceptionally involved.…”

Onychomycosis is the most frequently encountered nail disease and may be difficult to diagnose and treat. The objective of this study was to determine the prevalence, the clinical and mycological characteristics of onychomycosis in central Tunisia. It is a retrospective study performed over a 22-year period (1986-2007). It included 7151 patients (4709 women and 2442 men) with suspected fingernails and/or toenails onychomycosis. The patients were referred to the Mycology-Parasitology Laboratory of Farhat Hached hospital in Sousse for mycological examination. Both direct microscopy and culture of the nail material were performed to diagnose and identify the causative fungal species. Onychomycosis was confirmed in 78.6% of investigated patients (5624/7151). The positivity rate was higher in women as compared with men. In both men and women, fingernails were most frequently involved than toenails. No significant relation was found between gender and toenails onychomycosis, whereas fingernails were frequently involved in women. As far as aetiological agents are considered, dermatophytes, yeast and moulds were responsible for 49.9%, 47.4% and 2.7% of onyxis cases respectively. In fingernail infections, yeast were the most frequent fungi (83.6%), Candida albicans being the leading species (51.6%). In contrast, in toenail infections, dermatophytes were more frequent (74.1%). Trichophyton rubrum was by far the dominant species (88.1%). Yeast were observed more frequently in women whereas dermatophytes were more common in men. Moulds were involved in 4.2% of cases. The most frequent species were Aspergillus sp. and Chrysosporium sp. Onychomycosis is a frequent disease in central Tunisia. T. rubrum is the predominant agent in toenails infection and yeast, mainly C. albicans, in fingernails onychomycosis.
