BACKGROUND: Worldwide, dermatophytic infections are running a chronic course either due to ineffective treatment or emerging drug resistance. In the past three decades, there has been an increase in incidence and non-responsiveness to conventional antifungals, which suggests that there is a need of antifungal sensitivity testing. AIMS: This study was aimed at identifying clinico-mycological pattern of dermatophytic infections in patients attending thedermatology outpatient department of a tertiary care hospital, and to obtain the sensitivity pattern of isolates against six commonly used oral antifungals (fluconazole, terbinafine, itraconazole, ketoconazole, griseofulvin and voriconazole)...

Dermatophytes comprising the genera Trichophyton, Microsporum, and Epidermophyton are important causes of superficial mycoses. The number of infected patients and the distribution of species of these organisms in our hospital were unknown. We therefore aimed to investigate the clinical pattern of dermatophyte infections and to identify the species of these dermatophytes at the Dermatological Clinic of the Hospital for Tropical Medicine, Faculty of Tropical Medicine, Mahidol University, Bangkok in a 1-year period...

White and opaque cells of Candida albicans have the same genome but differ in gene expression patterns, metabolic profiles, and host niche preferences. We tested whether these differences (which include the differential expression of drug transporters) resulted in different sensitivities to 27 antifungal agents. The analysis was performed in two different strain backgrounds; although there was strain-to-strain variation, only terbinafine hydrochloride and caspofungin showed consistent, two-fold differences between white and opaque cells across both strains...

Fusarium are ubiquitous hyalohyphomycoses, usually encountered in the soil. They are the second unusual fungal pathogens after the Trichosporon. Intertrigo Fusarium sp. is a rare achievement. We report a case of intertrigos interorteils in an immunocompetent 45years old and a same case associated with a total onychodystrophy in an immunocompromised 75year-old. Laboratory diagnosis has found Fusarium solani confirmed with the positivity of a pure culture twice. Good progress was noted with terbinafine treatment...

Sporothrix brasiliensis has emerged as an important cause of sporotrichosis, particularly associated with feline and zoonotic cases. Owing to the paucity of data on antifungal activity against this species, the present study aimed to evaluate the in vitro susceptibility of clinical isolates of S. brasiliensis in the mycelial and yeast phases to itraconazole (ITZ), terbinafine (TRB), and amphotericin B (AMB). Thirty-five isolates from an outbreak of feline sporotrichosis in Southern Brazil were used. All of them were assessed in the yeast and filamentous phases using the broth microdilution technique in accordance with the respective reference protocols M27-A3 and M38-A2 of the Clinical and Laboratory Standards Institute (CLSI)...

Medications should be employed with caution in women of childbearing age who are pregnant or considering pregnancy. Compared to oral or parenteral agents, topical medications have limited systemic absorption and are deemed safer. However, their safety profile must be assessed cautiously due to the limited available data. In this article, we aggregate human and animal studies to provide recommendations on utilizing topical antiviral and antifungal medications in pregnancy. For antiviral medications, acyclovir and trichloroacetic acid are safe to use in pregnancy...

BACKGROUND: Sporothrix brasiliensis is the most virulent sporotrichosis agent. This species usually responds to antifungal drugs, but therapeutic failure can occur in some patients. Antifungal susceptibility tests have been performed on this species, but no clinical breakpoints (CBPs) are available. In this situation, minimal inhibitory concentration (MIC) distributions and epidemiological cutoff values (ECVs) support the detection of identification of resistant strains. OBJECTIVES: To study the MIC distributions of five antifungal drugs against S...

Terbinafine is one of the allylamine antifungal agents, whose target is squalene epoxidase (SQLE). This agent has been extensively used in the therapy of dermatophyte infections. The incidence of patients with tinea pedis or unguium tolerant to terbinafine treatment prompted us to screen terbinafine resistance of all Trichophyton clinical isolates from the laboratory of Centre Hospitalier Universitaire Vaudois collected over a three-year period, and to identify their mechanism of resistance. Among 2056 tested isolates, 17 (≈ 1%) showed reduced terbinafine susceptibility, all of which were found to harbor SQLE gene alleles with different single point mutations, leading to single amino acid substitutions at one of four positions (Leu(393), Phe(397), Phe(415) and His(440)) of the SQLE protein...

BACKGROUND: Chromomycosis, or chromoblastomycosis, is caused by cutaneous inoculation of dematiaceous fungi of telluric or plant origin. It is generally seen in tropical or subtropical zones. Treatment of the condition is known to be complex. Herein we report a case of chromomycosis contracted in a temperate region of Eastern Europe/Central Asia that was effectively treated with oral itraconazole and terbinafine in combination with cryotherapy. PATIENTS AND METHODS: A 44-year-old immunocompetent male subject consulted for a lesion on the buttocks that he had sustained 16 years earlier, and which, although never previously treated, had only become troublesome within the last few months...

Ophidiomyces ophiodiicola, the causative agent of snake fungal disease, is proposed as a serious threat to the conservation of several snake populations. The objective of this study was to determine the pharmacokinetic parameters of terbinafine administered through nebulization and a sustained subcutaneous implant as potential treatments of Ophidiomyces in reptiles. Seven adult cottonmouths (Agkistrodon piscivorus) were used in single-dose trials. Each snake was nebulized with terbinafine (2 mg/ml) for 30 min and had blood collected before nebulization and up to 12 hr after nebulization...

Subacute cutaneous lupus erythematosus (SCLE) is a well-defined subtype of lupus erythematosus, characterised by photosensitivity, annular and/or psoriasiform lesions, variable systemic involvement and presence of circulating SSA/anti-Ro antibodies. SCLE may be idiopathic or drug-induced. Both the idiopathic and drug-induced forms of SCLE are analogous in their clinical, serological and histological features. Drug-induced SCLE has been reported with various oral agents, but to our knowledge this is the first reported case due to a topical medication...
