Abstract
Onychomycosis is a common nail infection with several risk
factors such as genetic predisposition, ageing, psoriasis, HIV, certain
occupations, repeated trauma, continuous immersion in water and
contact with detergents. It is most commonly caused by
dermatophytes followed by moulds and yeasts. Lately, NDMs and
yeasts have been considered to be the principal aetiological agents of
onychomycosis in several studies.
Onychomycosis classification included DLSO, superficial
onychomycosis, PSO, endonyx onychomycosis and TDO, and was
extended to include mixed and secondary forms of infection.
Onychomycosis should be differentiated from other nail altering
diseases as; chronic paronychia, chronic dermatitis, psoriasis,
twenty-nail dystrophy, trauma, and tumors. Diagnosis is confirmed
using direct microscopy and fungal culture, or newer diagnostic
techniques which are not usually available. Treatment includes
topical and systemic antifungals, nail avulsion and debridement,
laser devices, PDT, iontophoresis, and ultrasound. Patient education
is mandatory to reduce recurrence and to seek treatment on
recurrence.
The study was conducted to evaluate the role of fractional
carbon dioxide laser and tioconazole 28% nail solution in the
treatment of fingernail onychomycosis as sole treatment modalities
and in combination. It included thirty female patients with fingernail
onychomycosis randomly divided into three equal groups.
