“…Según los resultados de estudios observacionales obtenidos sobre otitis externa maligna, la cirugía y los antibióticos intravenosos tuvieron mejores resultados cuando fueron acompañados de terapia de oxígeno hiperbárico (26)(27)(28)(29). En lo que respecta al tratamiento antibiótico, se prefiere que sea anti pseudomona, por ser el principal agente causal, correspondiente al uso de fluoroquinolonas que incluyen levofloxacina, ciprofloxacina ya que son las quinolonas activas contra pseudomona, más el uso de betalactámicos, conformando el tratamiento inicial por un tiempo variable de 6 a 8 semanas (30).…”

INTRODUCCIÓN: La otitis externa maligna (OEM), o también llamada otitis externa necrotizante, es una infección potencialmente mortal, que afecta principalmente al canal auditivo externo, produciendo osteomielitis del hueso temporal; se extiende hasta la base del cráneo y tejido circundante, provocando sepsis; llegando a comprometer los nervios craneales y generar afección multisistémica. Objetivos General: Describir el manejo actual de la otitis externa maligna. Objetivos específicos: 1) Determinar la etiología de la otitis externa maligna. 2) Determinar las complicaciones de la de la otitis externa maligna. MÉTODOS: se realizó una revisión sistemática según las guías PRISMA 2020 con búsqueda de artículos científicos, con el termino otitis externa maligna. Se recuperaron 40 artículos correspondientes a los últimos 5 años, obtenidos de bases de datos como Cochrane, Google académico, Medline, Mendeley, ScientDirect, IntechOpen. Los riesgos de sesgo en los estudios observaron diferencias sistemáticas por la heterogeneidad de los pacientes y los tratamientos entre los grupos. RESULTADOS: el manejo de la otitis externa maligna incluye tratamiento con antibióticos anti pseudomona como las fluoroquinolonas en combinación con un betalactámico y un antifúngico como la anfotericina B, voriconazol, fluconazol o equinocandinas; además del tratamiento con desbridamiento quirúrgico del canal auditivo y mastoidectomía radical, para evitar el riesgo de sepsis neurocraneal, obteniéndose buenos resultados. DISCUSIÓN: La otitis externa maligna, es una patología de rara ocurrencia que afecta a pacientes inmunocomprometidos, cuya morbimortalidad es alta, si no se trata adecuadamente. Sus principales agentes causales son: pseudomona aeruginosa, estafilococo aureus, Cándida spp, Aspergillus spp y Geotrichum. La importancia de esta investigación radica en optimizar la atención en el paciente con OEM, realizando un diagnóstico clínico e imagenológico oportuno, para brindar una alternativa terapéutica eficaz, basada en antibioticoterapia de amplio espectro, el tratamiento antifúngico, complementario al tratamiento quirúrgico, para evitar complicaciones.

Due to the falling water level in the Aral Sea and Muynak Lake, the content of salts dissolved in the water has gradually increased, and toxic elements have been deposited at the lake’s bottom and subsequently washed into the Aral region by the river. Bacteria, archaea and fungi are crucial for the cycling of several important inorganic nutrients in soils. From 15 genera and 31 species of recovered microscopic filamentous fungi, a big group was melanized, of which most of them were also phytopathogenic. The second group consisted of keratinophilic species. Isolated bacteria mainly included members of the genera Arthrobacter, Bacillus, Massilia, Rhodococcus and Nocardiopsis. High-throughput sequencing analysis permitted a better view of the mycobiome and prokaryotic communities (comprising archaea). The cultivation and sequencing approaches were shown to be complementary. The aim of the work was to identify soil microorganisms, including the order Halobacteriales, and to discover the differences in species diversity depending on soil salinity and the presence of PTEs in soil.

“…[14], and species of the Mucorales group [10] are reported to be the cause of this infection [1,15]. Additionally, very unusual cases of otomycosis caused by Saksenaea vasiformis, a species of the order Mucorales [16], and Scedosporium apiospermum in an immunocompetent patient [17] have recently been published. This narrative review aims to highlight the significant characteristics of otomycosis by reviewing the literature on the etiological-mycological, clinical and epidemiological features, diagnostic procedures, and previous experiences related to the treatment of this disease.…”

Otomycosis (OM) is a superficial fungal infection of the external auditory canal (EAC) with a worldwide prevalence ranging from 9% to 30%. Commonly, otomycoses are caused by Aspergillus (A.) niger complex and Candida spp. Other causative agents are yeasts of the genera Cryptococcus spp., Rhodotorula spp., Geotrichum candidum, dermatophytes (Trichophyton mentagrophytes), and non-dermatophytes molds (Fusarium spp., Penicillium spp., Mucorales fungi). The widest range of different species causing OM are found in the territories of Iran, India, China, Egypt, Mexico, and Brazil. Fungal infection of the EAC varies from mild to severe forms. It can be acute, subacute, or chronic, and is often unilateral, while the bilateral form is more common in immunocompromised patients. From an epidemiological point of view, tropical and subtropical climates are the most significant risk factor for the development of otomycosis. Other predisposing conditions include clothing habits, EAC hygiene practices, long-term antibiotic therapy, diabetes, and immunodeficiency. Since it is often difficult to distinguish otomycosis from an infection of a different origin, laboratory-based evidence, including standard procedures (microscopy and cultivation), is essential for diagnosis. For the treatment of this superficial fungal infection, there are no official therapeutic guidelines and protocols. However, many antifungals for local application, such as polyene, imidazoles, and allylamines, can be applied, as well as systemic antimycotics (triazoles) in severe forms of infection.
