The prevalence of Candida onychomycosis in Southeastern Serbia from 2011 to 2015.

Despite the increasing of onychomycosis caused by Candida spp., in referent literature, there is still data insufficiency about this nail infection. The objectives of this retrospective study were to determine epidemiological characteristics of Candida onychomycosis, the antifungal susceptibility of isolated species in vitro, and to compare the results of antifungal susceptibility testing with conducted treatment in period from 2011 to the end of March 2015. Out of 761 patients who were underwent clinical and mycological examinations, 137 had Candida species isolated from nails. The dominant species was Candida albicans (C. albicans) (36.59%) followed by C. parapsilosis (23.78%), C. krusei (9.76%), and C. guilliermondii (6.71%). Antifungal susceptibility in vitro testing showed good susceptibility to antimycotics, except C. krusei, which was resistance to fluconazole (FCZ) and isolates of C. tropicalis and C. glabrata which were dose dependent to itraconazole (ITZ) and fluconazole. Evaluation of medical histories determined that combined therapy, which included pulsed systemic regimen of ITZ with topical application of clotrimazole, had better clinical outcomes regarding the proscribed only topical application of clotrimazole. Multidisciplinary approach of dermatologists and mycologists is required in solving the problem of onychomycosis, which is the dominant nail disease.

[Kyrle's disease]. / Kyrleova bolest.

INTRODUCTION: Hyperkeratosis follicularis et parafollicularis in cuten penetrans known as Kyrle's disease is a recessive hereditary genodermatosis. Generally, Kyrle's disease appears between 30 to 50 years of age and women are affected more than men. CASE REPORT: We report a case of a 40-year-old man, a worker in a cement factory, who noticed the first skin lesions six years ago. Those were follicular papules on the left leg. He had been in good health beforehand, although an alcoholic for many years. Based on laboratory and other findings, chronic hepatitis was diagnosed. Histopathological analysis of skin lesions showed presence of hyperkeratosis and partial parakeratosis with acanthosis of the epidermis. DISCUSSION: Kyrle's disease is classified among the perforating dermatoses with perforating folliculitis, perforating serpiginous elastosis and perforating reactive collagenosis. Kyrle's disease is often associated with hepatic, renal or diabetic disorders, and may be a paraneoplastic disease. CONCLUSION: The course of this disease is chronic. If the associated diseases are treated, patients may have a better prognosis.
