Fungal infections have become more frequent in recent years, presenting themselves with greater prevalence in patients with basic diseases that compromise the immune system and predispose to other risk factors such as invasive devices and use of antibacterial. The etiological agents of these mycoses are filamentous dermatophyte fungi, filamentous nonBrazilian Journal of health Review Braz. J. Hea. Rev., Curitiba, v. 3, n. 5, p. 12873-12880 set./out. 2020. ISSN 2595-6825 12875 dermatophyte fungi (FFND) and yeasts. This study has shown importance in the observation of the clinical aspects of lesions suggestive of mycosis, as well as the direct mycological examination in the presumptive diagnosis of superficial mycoses in internal patients in the Intensive Care Unit (ICU) of the University Hospital (HU) located in Petrolina-PE. The patients who entered the HU ICU from January 2018 to January 2019, after ethical procedures, were analyzed for the presence of suspected superficial mycoses and the respective clinical samples were collected and processed for direct examination through clarification with 30% potassium hydroxide (KOH). The mean age of the patients was 39.4, ranging from 24 to 68 years and a mean length of stay of 15.1 days. None of the patients was in use of antifungal. Of 23 patients, 10 had characteristic lesions of ungual mycosis, 4 had characteristic lesions of tinea corporis. Of the 10 suspected nail mycoses, 4 cases were confirmed, all in toenails and caused by round, blastosporated and hyaline yeasts, with pseudo hyphae and pseudo-mycelium suggestive of Candida sp. No case of tinea corporis was confirmed. The nails of the pododactyls went to the most affected areas. The use of closed shoes and even vascular impairment in the lower limb are considered primordial predisposing factors for the development of such infection. This study exposes the presence of yeasts considered potentially pathogenic in nails of patients admitted to the ICU, which suggests the need for further studies regarding the prevalence of these microorganisms in our region, since their relevance is due to the fact that they are associated with infections in immunosuppressed individuals dependent on intensive care. The simple observation of the clinical aspects and the direct mycological examination in suspected deinfectionsfungal lesions are important for identifying possible outbreaks of systemic infections, besides being a fast and low cost diagnostic method, making possible in a fast way the management of the patient with a nail disease.
