Pharmaceutics 2022 Jun 11;14(6). Epub 2022 Jun 11.

Department of Otorhinolaryngology, Head and Neck Surgery, Lower Saxony Center for Biomedical Engineering, Implant Research and Development (NIFE), Hannover Medical School, Stadtfelddamm 34, 30625 Hannover, Germany.

Postoperative restenosis in patients with external ear canal (EEC) atresia or stenosis is a common complication following canaloplasty. Our aim in this study was to explore the feasibility of using a three dimensionally (3D)-printed, patient-individualized, drug ((dexamethasone (DEX)), and ciprofloxacin (cipro))-releasing external ear canal implant (EECI) as a postoperative stent after canaloplasty. We designed and pre-clinically tested this novel implant for drug release (by high-performance liquid chromatography), biocompatibility (by the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay), bio-efficacy (by the TNF-α (tumor necrosis factor-alpha)-reduction test (DEX) and inhibition zone test (for cipro)), and microbial contamination (formation of turbidity or sediments in culture medium).

mSphere 2022 04 21;7(2):e0102221. Epub 2022 Mar 21.

Department of Plant Pathology and Environmental Microbiology, Center for Infectious Disease Dynamics, Pennsylvania State Universitygrid.29857.31, University Park, Pennsylvania, USA.

White-nose syndrome (WNS), responsible for the mass mortality of North American bats, lacks economically viable and practical models for infection, the causative agent of WNS. Not only are many susceptible North American insectivorous bats nearing extinction and, thus, scarce for experimental studies, but they are difficult to care for and maintain in captivity because of their specialized habitats and diets. In this study, we explored porcine ears as a potential substrate for studying infection development and the dynamics of growth in the laboratory. Read More

Department of Otolaryngology, Nepean Hospital, Kingswood, NSW, 2747, Australia.

Background: Ramsay Hunt Syndrome (RHS) is a neurotological disorder involving the reactivation of the varicella-zoster virus (VZV) in the geniculate ganglion of the facial nerve (Sweeney and Gilden in J Neurol Neurosurg Psychiatry 71:149-154, 2001). The characteristic presentation involves ipsilateral lower motor neuron type facial paresis, auricular pain with or without hearing impairment, and vesicular lesions of the external auditory canal and outer ear. Involvement of the facial and vestibulocochlear nerve is typical in RHS, whilst multiple cranial neuropathies are rare and associated with poorer prognosis and systemic complications (Arya et al.

[Herpes zoster of the external ear and face].

Rev Med Suisse 2021 Oct;17(753):1684-1689

Service d'ORL et chirurgie cervico-faciale, Réseau hospitalier neuchâtelois, 2000 Neuchâtel.

The development of vesicles on the pinna and external auditory canal will often correspond to a herpes zoster infection of one of the many nerves innervating the external ear. In case of associated facial paralysis, vertigo or sudden deafness the patient should undergo a thorough neuro-otologic examination and receive appropriate treatment. This article proposes a reminder of the various clinical presentations of herpes zoster oticus with some neuro-anatomical considerations. Read More

The Epithelial Cell Glycocalyx in Ocular Surface Infection.

Front Immunol 2021 23;12:729260. Epub 2021 Aug 23.

Department of Ophthalmology, Schepens Eye Research Institute of Massachusetts Eye and Ear, Harvard Medical School, Boston, MA, United States.

The glycocalyx is the main component of the transcellular barrier located at the interface between the ocular surface epithelia and the external environment. This barrier extends up to 500 nm from the plasma membrane and projects into the tear fluid bathing the surface of the eye. Under homeostatic conditions, defense molecules in the glycocalyx, such as transmembrane mucins, resist infection. Read More
