Background:Candida auris is a globally emerging, multidrug-resistant fungal pathogen that causes healthcare-associated outbreaks and can be misidentified in clinical laboratories. Most US C. auris cases occur in hospitalized or long-term care patients with underlying medical conditions. Also, 4 global phylogenetic C. auris clades largely cluster geographically. Receiving health care abroad is a risk factor for US C. auris cases. In December 2019, the Minnesota Department of Health (MDH) confirmed Minnesota’s first C. auris case, isolated from the external ear canal of a healthy young adult outpatient with right-sided otitis externa. We describe the investigation and response for this uncommon US presentation of C. auris. Methods: The MDH initiated mandatory reporting and submission of confirmed or possible C. auris isolates in August 2019. The MDH Public Health Laboratory (MDH-PHL) confirmed C. auris by MALDI-TOF (Bruker) from an isolate submitted by a hospital laboratory as C. duobushaemulonii to rule out C. auris. The MDH-PHL performed broth microdilution antifungal susceptibility testing (AFST). The CDC Mycotics Diseases Branch laboratory performed whole-genome sequencing (WGS). The MDH epidemiologists obtained a patient history through interviews with healthcare staff and the patient, and they collected environmental samples from otoscopes. The MDH-PHL tested environmental samples by C. auris RT-PCR and culture. The MDH recommended disinfection of examination rooms and otoscopes and 3 months of C. auris surveillance for patients evaluated with otoscopes who later returned with otic inflammation. Swabs from the patient’s axilla, groin, and external ear canals were tested for C. auris by PCR at the MDH-PHL. Results: The patient reported recurrent right ear infections in 2016 during a 16-month visit to South Korea, with treatment in multiple ENT clinics. December 2019 otitis resolved after treatment with oral amoxicillin/clavulanate and otic ciprofloxacin/dexamethasone. AFST showed resistance to fluconozale and susceptibility to 8 antifungals, including echinocandins. WGS placed the isolate in the East Asian clade, indicating similarity to isolates from South Korea and Japan. Environmental cultures were negative. The asymptomatic left ear was colonized with C. auris; other sites were negative. As of January29, 2020, no additional cases were detected. Conclusions: We identified prolonged colonization of C. auris in the external ear canals of a healthy patient. WGS and travel in South Korea, including ENT clinic exposure, provide strong evidence of C. auris acquisition in South Korea. No spread has been reported in Minnesota. Deliberate communication with clinical laboratories regarding ruling out C. auris was key to case discovery. Clinicians should be aware of C. auris epidemiology, including healthcare exposure abroad, particularly in young, healthy patients.Funding: NoneDisclosures: None

Canal Atresia

A 3 yr old male castrated Labrador retriever presented for evaluation and treatment of bilateral atresia of the external ear canals. The owners reported that the dog could hear only loud and high-pitched noises. Computed tomography of the head revealed intact vertical and horizontal ear canals filled with debris and a debris-filled right tympanic bulla. Air- and bone-conducted brainstem auditory evoked response (BAER) testing revealed an elevated response threshold to air-conducted stimuli and greater amplitude waveforms evoked by bone-conducted stimuli. The ear canals were surgically corrected via lateral ear canal resection. BAER testing postoperatively revealed a decrease in the air-conducted BAER threshold. This case is an example of the use of bone-conducted BAER testing to aid in the diagnosis of conductive deafness, and in determining prognosis for normal hearing after surgical treatment of external ear canal atresia.

Biofeedback was reported as an effective concept for bruxism treatment, through increasing patient’s awareness of the habit. During bruxing both ear canals become tighter, therefore, an in-ear device can provide biofeedback. The in-ear device is fitted to the ear canal in physiological status, during bruxing the ear-canal tightens resulting in stress on the canal walls and unpleasant feeling. Subsequently, patients stop their bruxing habit. The aim of this study is to provide first clinical evidence that in-ear devices have a positive impact on relieving bruxism in patients. Despite the low number of patients, this early study was designed as a controlled prospective study. The trial included seven female patients with a median age of 47.3 years (23–64 years). Only two patients implemented their devices for eight and seven months, respectively. One patient reported a relief in her symptoms, like headaches and pain intensity during the night, by 50% after three month and 80% after six months. Despite the limited number of participants, the study reflects a potential of Intra-aural devices as effective biofeedback devices in treating bruxism.

Objectives Feline otitis externa is a multifactorial dermatological disorder about which very little is known. The objective of this study was to map the prevalence of external ear canal disorders and the pathogens causing otitis externa in stray cats roaming around the region of Ghent, Belgium. Methods One hundred and thirty stray cats were randomly selected during a local trap–neuter–return programme. All cats were European Shorthairs. This study included clinical, otoscopic and cytological evaluation of both external ears of each cat. Prospective data used as parameters in this study included the sex, age and body condition score of each cat, as well as the presence of nasal and/or ocular discharge, and the results of feline immunodeficiency virus (FIV) and feline leukaemia virus (FeLV) Snap tests. Results Remarkably, very few (sub)clinical problems of the external ear canal were found in the stray cat population. Malassezia species was by far the most common organism found in the external ear canals of the 130 stray cats. A total of 96/130 (74%) cats were found to have Malassezia species organisms present in one or both ears based on the cytological examination. No correlation was found between the parameters of sex, age, body condition score, the presence of nasal and/or ocular discharge and FIV and FeLV status, and the presence of parasites, bacteria or yeasts. Conclusions and relevance This study provides more information about the normal state of the external ear canal of stray cats. The ears of most stray cats are relatively healthy. The presence of Malassezia species organisms in the external ear canal is not rare among stray cats.

Rate Of Growth

This paper assessed 300 surfboard riders, comprising 229 males and 71 females to determine the prevalence and rate of growth of exostoses in this population. A group of cold water swimmers and a control group were also examined. Significant obstruction, defined as two thirds or more occlusion of the ear canal was noted in 90 of the male surfers and 10 female surfers. This degree of occlusion was found in seven of the 32 cold water swimmers. A male surfer who has surfed regularly for 20 years or more has a one in two chance of developing significant obstruction of the external ear canal resulting from exostoses and this is a three in seven chance for females.

AbstractReports concerning the lesions of the skin coverage of the external ear canal in malignant external otitis (M.E.O.) are very few. To evaluate this problem, we studied the skin lesions of 45 skin biopsies from 40 M.E.O. patients, 23 from regions covering the osseous part of the ear structure, seven from the cartilaginous part of the external canal and 15 from both parts. The epidermis was normal in nine, thickened in 16, with acanthotic thickening and pseudoepitheliomatous hyperplasia in 20. In the dermis the amount of collagen was normal, but it was infiltrated by the inflammatory process. Acute inflammation was observed in 16 biopsies, subacute in 23, chronic in six. A mixture of acute and chronic changes was present in 18 biopsies. No major abnormalities of the vasculature could be detected. The distinguishing pathological feature of M.E.O. concerns the typical topographic distribution of the inflammation in the osseous part of the external ear canal.

Veterinary Surgeon

Otitis externa is a common problem in primary care veterinary practice. While the diagnosis and treatment of disease is the responsibility of the attending veterinary surgeon, the veterinary nurse, as an integral part of the veterinary surgeon-led team, plays an important role in the investigation and management of disease. Veterinary nurses are more than capable of assessing the external ear canal both macroscopically and cytologically to help the veterinary surgeon to make a diagnosis. Client facing nurse communications can help with the administration of therapy, provide owner support during treatment to increase compliance and help with follow-up assessments.
