1. Kerion celsi caused by Trichophyton tonsurans in an adult
Abstract Tinea capitis is an uncommon infection in adults, and predominantly affects women and the elderly with hormonal disorders and immunosuppression. Clinical features are often polymorphic and atypical. A kerion celsi case in an elderly female patient with type 2 diabetes mellitus and menopause is presented. The diagnosis was established by direct exami

2. Deep dermatophytosis caused by Trichophyton rubrum in immunocompromised patients
Abstract In immunosuppressed patients, dermatophytosis can be more invasive, affecting the dermis and subcutaneous tissues. The authors describe the cases of two patients with kidney and heart transplanted, respectively, that developed a deep dermatophytosis caused by Trichophyton rubrum, confirmed by culture and DNA sequencing. Both patients had concomitant

3. Synthesis, Spectroscopic Characterization, DFT Calculations and Preliminary Antifungal Activity of New Piperine Derivatives
Four new piperine derivatives, PC1-PC4, were synthesized, and their structures were fully characterized by infrared (IR) and 1H and 13C nuclear magnetic resonance (NMR) spectroscopies. Quantum chemical calculations were performed using density functional theory (DFT) with the B3LYP-D3/6-31G(d,p) and 6-311+G(2d,p) basis sets. Electronic properties, such as th

4. Pandemia, distanciamento social e academia - Dançando no escuro 20 anos depois
Abstract Pseudomycetoma is an extremely rare deep mycosis, caused by dermatophytic fungi that penetrate the tissue from infected follicles of tinea capitis. Both clinically and histopathology are similar to eumycetoma, being distinguished through the isolation of the fungus, which in the case of pseudomycetoma can be Microsporum spp. or Trichophyton spp. gen

6. Tinea capitis: dermoscopy and calcium fluorescent microscopy as highly efficient and precise diagnostic tools
Abstract Tinea capitis comprising of tinea favosa and kerion is mostly seen in school-aged children. Some tinea capitis often presented with insignificant findings under the naked eyes are easily overlooked. The authors describe an unusual case of tinea capitis caused by Trichophyton violaceum. The patient was an 8-year-old girl, with a history of pruritus o

7. In situ immune response in human dermatophytosis: possible role of Langerhans cells (CD1a+) as a risk factor for dermatophyte infection
ABSTRACT Dermatophytosis is a cutaneous mycosis caused by a plethora of keratinophilic fungi, but Trichophyton rubrum is the most common etiological agent. Despite its high prevalence worldwide, little is known about the host defense mechanisms in this infection, particularly the in situ immune response. Using an immunohistochemistry approach, we investigate

8. Occurrence of dermatophytoses in patients from the Sistema Único de Saúde
Abstract: Background: Dermatophytosis is a cutaneous disease caused by filamentous keratinophilic fungi belonging to the genera Trichophyton, Microsporum and Epidermophyton, which present a high prevalence in the general population, being among the most common mycoses affecting about 20% of the world's population. Objective: To carry out the epidemiologica

9. Evaluation of the antimicrobial and antioxidant activity of 7-hydroxy-4’, 6-dimethoxy-isoflavone and essential oil from Myroxylon peruiferum L.f
Abstract: This study evaluated the antibacterial, antifungal, and antioxidant effect of 7-hydroxy-4’,6-dimethoxy-isoflavone and essential oil of Myroxylon peruiferum. The compound was isolated and its structure elucidated by NMR. The chemical composition of essential oil determined by GC-MS analysis. To evaluation of antimicrobial activity, the Minimum Inh

11. Copaiba Oil and Its Constituent Copalic Acid as Chemotherapeutic Agents against Dermatophytes
Copaiba oil, an oleoresin extracted from Copaifera genus, has been widely used in popular medicine for the treatment of several diseases. The aim of this study was to investigate the antifungal activity of the copaiba oil and its isolated compounds caryophyllene oxide, copalic acid and acetoxycopalic acid against Trichophyton rubrum, Trichophyton mentagrophy

12. In vitro antifungal activity of organic compounds derived from amino alcohols against onychomycosis
Abstract Onychomycosis is a fungal infection of the nail caused by high densities of filamentous fungi and yeasts. Treatment for this illness is long-term, and recurrences are frequently detected. This study evaluated in vitro antifungal activities of 12 organic compounds derived from amino alcohols against standard fungal strains, such as Trichophyton rubru
