Cutaneous leishmaniasis typically presents as a painless papule progressing to an ulcer or plaque. In this case study of the ear, the disease manifested as a small painful bump progressing into redness and swelling about the ear with purulent drainage. After multiple oral/intravenous antipseudomonal, antistaphylococcal, and antifungal treatments, there was no improvement. The skin progressed to an erythematous plaque and hemorrhagic ulcer; punch biopsy and speciation revealed Leishmaniasis guyanensis. The patient was switched to a seven-dose course of intravenous L-amphotericin B (visceral leishmaniasis protocol)...

Jonathan C Simmonds, Mark Vecchiotti
OBJECTIVE: To determine if patients with Langerhans Cell Histiocytosis (LCH) of the temporal bone have a higher risk of developing cholesteatoma. METHODS: Review of literature and cross-sectional weighted analysis of patients under 19 with a diagnosis of LCH from the National Inpatient Sample (NIS) and Kids' Inpatient Database (KID) from 2000 to 2013. ICD-9 codes and demographics were analyzed; pairwise comparisons and multivariate analyses were performed. RESULTS: Only seven cases of cholesteatoma after the treatment for LCH of the temporal bone have been documented in the literature...

BACKGROUND: The German Shepherd Dog (GSD) has been widely used for a variety of working roles. However, concerns for the health and welfare of the GSD have been widely aired and there is evidence that breed numbers are now in decline in the UK. Accurate demographic and disorder data could assist with breeding and clinical prioritisation. The VetCompass(TM) Programme collects clinical data on dogs under primary veterinary care in the UK. This study included all VetCompass(TM) dogs under veterinary care during 2013...

OBJECTIVE: Otowicks are used to treat otitis externa with significant ear canal oedema. This study investigates how well drops penetrate through to reach the deep canal and whether it is safe to leave otowicks in the canal for more than 2 days. METHODS: Sterile otowicks were inserted into mock ear canals and vertically over pseudomonas-seeded agar plates whilst gentamicin or ciprofloxacin drops were administered. The time taken for drops to penetrate through the otowick was recorded...

The meatoplasty of the external auditory canal is a frequently performed otologic procedure in recurrent otitis externa, eczema or frequent accumulation of cerumen due to a narrow meatus of the external ear canal. Numerous surgical techniques have been described. The M-meatoplasty described by Mirck for addressing the external meatus is widely used. However, this technique does not sufficiently enlarge the external ear canal in all cases. Specifically in patients where the ear canal narrowing is most prominent in the postero- and/or anterosuperior quadrants of the lateral meatus the technique needs some modifications...

OBJECTIVE: Otitis externa is normally treated with daily topical medication. Longer application intervals may be useful to facilitate therapy. In this study, the in vivo efficacy of a gel preparation containing marbofloxacin, dexamethasone and enilconazole was compared to that of a commercial otologic agent containing marbofloxacin, dexamethasone and clotrimazole based on clinical signs, ear cytology and bacterial/fungal cultures. MATERIAL AND METHODS: A gel preparation (group A) or a registered otologic agent (group B), respectively, was applied to 41 dogs...

Otitis externa caused by fungi (otomycosis) occurs more commonly in tropical areas with high moisture than in temperate regions. Bilateral otomycosis is, however, rarely reported. In a case of bilateral otitis externa in a 56-year-old male patient in Taiwan, direct microscopic examination of the cerumen as well as isolation of strains indicated the presence of two Aspergillus species being different in each of both ears. The species were identified by DNA sequence comparisons and additional morphological confirmation of diagnostic characteristics as Aspergillus flavus and Aspergillus terreus...

CASE SUMMARY: A 14-year-old female spayed cat was referred for recurrent otitis externa and unusual proliferative lesions in both ear canals. The affected pinnae and external ear canals were covered with large reddish-to-dark-brown verrucous and necrotic tissue. Friable material and exudates occluded both ear canals. Proliferative lesions developed in both ears 2-3 weeks before referral. The histopathological diagnosis from two biopsies obtained from the friable materials with endoscopic biopsy forceps was proliferative and necrotising otitis externa (PNOE)...

PURPOSE: Skull base osteomyelitis (SBOM) is an inflammatory process which often arises from malignant otitis externa (MOE); the diffuse skull base and adjacent soft tissue involvement may be mistaken at initial imaging for advanced nasopharyngeal carcinoma (NPC), especially if there is no prior knowledge of MOE, direct spread from the sphenoid sinus or in atypical presentations of MOE. This study aims to evaluate imaging features on MR that may differentiate SBOM from NPC. MATERIALS AND METHODS: The MR examinations of 26 patients diagnosed with SBOM between January 1996 and January 2013 were retrospectively reviewed...

OBJECTIVE: Knowledge of ENT is important for many doctors, but undergraduate time is limited. This study aimed to identify what is thought about ENT knowledge amongst non-ENT doctors, and the key topics that the curriculum should focus on. METHODS: Doctors were interviewed about their views of ENT knowledge amongst non-ENT doctors, and asked to identify key topics. These topics were then used to devise a questionnaire, which was distributed to multiple stakeholders in order to identify the key topics...

INTRODUCTION: Although otitis externa (OE) is a common disease, data related to (military) divers are limited. This study aimed to determine the incidence of OE in military divers during their initial training. We also wished to consider seasonal influences on incidence and whether early detection increases completion of the diving course. METHODS: From January 2011 to October 2016 the Royal Netherlands Navy Diving School trained 189 divers. Up to December 2015 we used the training records for the analyses...
