Otalgia (ear pain) is a common presentation in the primary care setting with many diverse causes. Pain that originates from the ear is called primary otalgia, and the most common causes are otitis media and otitis externa. Examination of the ear usually reveals abnormal findings in patients with primary otalgia. Pain that originates outside the ear is called secondary otalgia, and the etiology can be difficult to establish because of the complex innervation of the ear. The most common causes of secondary otalgia include temporomandibular joint syndrome and dental infections...

BACKGROUND: Antimicrobial resistance and antimicrobial stewardship are of ever-increasing importance in veterinary medicine. Re-purposing of old drugs that are not used in human medicine is one approach that addresses the emergence of multidrug resistance in canine skin and ear infections, and can reduce the use of critically important human antibiotic classes. HYPOTHESIS/OBJECTIVES: To determine the antimicrobial activity of narasin, a polyether ionophore conventionally used as a rumen modifier and anticoccidial agent in production animals, against common clinical isolates of canine otitis externa (OE)...

A new species of Demodex was detected in the earwax of a dog with otitis externa in Saitama Prefecture, Japan, in July 2010. The opisthosoma length of the mite was slightly shorter than 1/2 of its body length, which was different from the other species in domestic dogs, D. canis and D. injai, but was similar to the form of mites termed "short-bodied species", including D. cornei. However, the stubby external form was morphologically different from those of "short-bodied species", excluding a case without a species description reported from Greece...

In patients with repeated exposure to cold water, such as cold water surfers and kayakers, the reactive exostoses can occur in the external auditory canal. The external auditory canal exostoses are multiple, benign bony growths. They can cause external auditory canal stenosis, leading to repeated otitis externa and potentially conductive hearing loss. It is vital to consider this entity in susceptible patients who report hearing loss, as timely intervention such as proper ear protection equipment can lower the risk of developing severe external auditory canal exostoses...

REVIEW
Florian Sparber, Salomé LeibundGut-Landmann
The skin of mammalian organisms is home for a myriad of microbes. Many of these commensals are thought to have beneficial effects on the host by critically contributing to immune homeostasis. Consequently, dysbiosis can have detrimental effects for the host that may manifest with inflammatory diseases at the barrier tissue. Besides bacteria, fungi make an important contribution to the microbiota and among these, the yeast Malassezia widely dominates in most areas of the skin in healthy individuals. There is accumulating evidence that Malassezia spp...

A four-year-old female French bulldog was presented for evaluation of acute, left-sided peripheral vestibular syndrome. Computed tomographic (CT) examination of the head revealed the presence of air within the left cochlea and vestibule, consistent with pneumolabyrinth. This was concurrent with ipsilateral otitis media and externa. Pneumolabyrinth is an uncommon finding in humans and is most frequently due to head trauma and temporal bone fracture. This is the first report describing pneumolabyrinth in a dog, apparently of nontraumatic origin in this case...

Christopher Thompson, Rohit Gohil, Alex Bennett
An 80-year-old Caucasian man presented with an incidental and asymptomatic lesion in his right ear thought to be secondary to his use of hearing aids for presbycusis. He used Lyric hearing aids, designed for 24 hours-a-day use for 4 months at a time and had no other previous otological problems. He underwent a bony meatoplasty and vascular flap reconstruction via a retroauricular approach to remove the lesion for histological analysis and regrafting of the area. The lesion was confirmed on histopathology as an ear canal cholesteatoma...
