Acute otitis externa is a common condition involving inflammation of the ear canal. The acute form is caused primarily by bacterial infection, with Pseudomonas aeruginosa and Staphylococcus aureus the most common pathogens. Acute otitis externa presents with the rapid onset of ear canal inflammation, resulting in otalgia, itching, canal edema, canal erythema, and otorrhea, and often occurs foll...

Ear mites (Otodectes cynotis) and ear canal tumors are highly prevalent among federally endangered Island foxes (Urocyon littoralis catalinae) living on Santa Catalina Island off the coast of Southern California. Since studies began in the 1990s, nearly all foxes examined were found to be infected with ear mites, and ceruminous gland tumors (carcinomas and adenomas) were detected in approximate...

During a survey of the occurrence of Malassezia species in the external ear canals of cats without otitis externa, Malassezia furfur was isolated. This is the first report of the isolation of M. furfur from cats.

OBJECTIVE To isolate and characterize bacteria and fungi from acute otitis externa (AOE) and to obtain susceptibility profiles on each bacterial isolate. STUDY DESIGN Prospective core series. METHODS Specimens were collected from the external canals of subjects with clinically diagnosed acute otitis externa. Species-level identification for each bacterial isolate recovered was obtained by c...

Acute otitis externa (AOE) is defined as a diffuse inflammation of the external ear canal, which may also involve the pinna or tympanic membrane (1). This condition is also known as “swimmer’s ear” or “tropical ear” due to a higher prevalence in individuals with prolonged water exposure during swimming or who live in warm and humid climates (2). The annual incidence of AOE is about 1:100 to 1:2...

Market collapse is one of the most dramatic events in economics. Such a catastrophic event can emerge from the nonlinear interactions between the economic agents at the micro level of the economy. Transient chaos might be a good description of how a collapsing market behaves. In this work, we apply a new control method, the partial control method, with the goal of avoiding this disastrous event...
