Histopathologic Spectrum of Intraoral Irritant and Contact Hypersensitivity Reactions: A Series of 12 cases.

Head Neck Pathol 2021 Apr 26. Epub 2021 Apr 26.

Department of Oral Medicine Infection and Immunity, Harvard School of Dental Medicine, 188 Longwood Avenue, Boston, MA, 02115, USA.

Background: Irritant contact stomatitis (ICS) and contact hypersensitivity stomatitis (CHS) are often caused by alcohol, flavoring agents and additives in dentifrices and foods, and contactants with high or low pH. A well-recognized contactant for ICS is Listerine™ mouthwash, while that for CHS is cinnamic aldehyde. However, many other flavoring agents and even smokeless tobacco are contactants that cause mucosal lesions that are entirely reversible. Read More

High dose of vesicular stomatitis virus-vectored Ebola virus vaccine causes vesicular disease in swine without horizontal transmission.

Emerg Microbes Infect 2021 Dec;10(1):651-663

Department of Diagnostic Medicine/Pathobiology, Center of Excellence for Emerging and Zoonotic Animal Diseases (CEEZAD), College of Veterinary Medicine, Kansas State University, Manhattan, KS, USA.

The recent impact of Ebola virus disease (EVD) on public health in Africa clearly demonstrates the need for a safe and efficacious vaccine to control outbreaks and mitigate its threat to global health. ERVEBO® is an effective recombinant Vesicular Stomatitis Virus (VSV)-vectored Ebola virus vaccine (VSV-EBOV) that was approved by the FDA and EMA in late 2019 for use in prevention of EVD. Since the parental virus VSV, which was used to construct VSV-EBOV, is pathogenic for livestock and the vaccine virus may be shed at low levels by vaccinated humans, widespread deployment of the vaccine requires investigation into its infectivity and transmissibility in VSV-susceptible livestock species.

Validation of a binary ethylenimine (BEI) inactivation procedure for biosafety treatment of foot-and-mouth disease viruses (FMDV), vesicular stomatitis viruses (VSV), and swine vesicular disease virus (SVDV).

Vet Microbiol 2021 Jan 16;252:108928. Epub 2020 Nov 16.

Foreign Animal Disease Diagnostic Laboratory, National Veterinary Services Laboratories, Animal and Plant Health Inspection Service, United States Department of Agriculture, Plum Island Animal Disease Center, 40550 Route 25, Orient Point, NY 11957, USA. Electronic address:

Binary ethylenimine (BEI) has been widely used as a virucide to inactivate viruses. For regulatory exclusion of a select agent, the United States Federal Select Agent Program (FSAP) requires an inactivation procedure that renders a select agent non-viable but allows the select agent to retain antigenic characteristics for future use must be validated, and the inactivated agent must be confirmed by a viability testing. In this curve-based validation study, we examined impacts of BEI concentration, treatment temperature, and time on our in-house inactivation procedures of Foot-and-Mouth Disease Virus (FMDV), Vesicular Stomatitis Virus (VSV), and Swine Vesicular Disease Virus (SVDV).

Development of Spray Formulations Applied to the Oral Mucosa Using Non-lamellar Liquid Crystal-Forming Lipids.

Chem Pharm Bull (Tokyo) 2020 ;68(11):1025-1033

Faculty of Pharmacy and Pharmaceutical Sciences, Josai University.

We examined the physicochemical and biochemical properties of mono-O-(5,9,13-trimethyl-4-tetradecenyl)glycerol ester (MGE), including ease of handling, high bioadhesiveness, quick and stable in vivo self-organization (forming a non-lamellar lyotropic liquid crystal [NLLC]), and high biomembrane permeation enhancement. We prepared MGE oral mucosa-applied spray preparations containing triamcinolone acetonide (TA), which is widely used in the treatment of stomatitis, and we examined the usefulness of the MGE preparations compared with commercially available oral mucosal application preparations containing 2,3-dihydroxypropyl oleate (1-mono(cis-9-octadecenoyl)glycerol (GMO) (previously studied as an NLLC-forming lipid) preparation. As a result, the MGE preparation applied to the oral mucosa can rapidly formed an NLLC with reverse hexagonal or cubic structures, or a mixture, on contact with water. Read More

Ebola virus - one of the deadliest viral diseases, with a mortality rate around 90% - damages the immune system and organs, with symptoms including episodic fever, chills, malaise and myalgia. The Recombinant Vesicular Stomatitis Virus-based candidate vaccine (rVSV-ZEBOV) has demonstrated clinical efficacy against Ebola in ring-vaccination clinical trials. In order to evaluate the potential effect of this candidate vaccine, we developed risk equations for the daily risk of Ebola infection both currently and after vaccination. Read More

Oral Vaccination With Recombinant Vesicular Stomatitis Virus Expressing Sin Nombre Virus Glycoprotein Prevents Sin Nombre Virus Transmission in Deer Mice.

Front Cell Infect Microbiol 2020 8;10:333. Epub 2020 Jul 8.

Department of Medical Microbiology and Infectious Diseases, University of Manitoba, Winnipeg, MB, Canada.

Sin Nombre virus (SNV) is the major cause of hantavirus cardiopulmonary syndrome (HCPS) in North America, a severe respiratory disease with a high fatality rate. SNV is carried by , or deer mice, and human infection occurs following inhalation of aerosolized virus in mouse excreta or secreta, often in peri-domestic settings. Currently there are no FDA approved vaccines or therapeutics for SNV or any other hantaviruses, therefore prevention of infection is an important means of reducing the disease burden of HCPS.

Arch Oral Biol 2020 Sep 20;117:104822. Epub 2020 Jun 20.

Department of Prosthodontics and Periodontology, University of Campinas (UNICAMP), Piracicaba Dental School, Piracicaba, Brazil. Electronic address:

Objective: Overcoming substantial shortcomings of soft liners as physico-chemical changes and liner-biofilm-related infections remains a challenge in the rehabilitation treatment. In this study, protective non-thermal plasma (NTP) treatments were developed on the soft liner surface to improve its surface and physico-chemical properties and to reduce fungal colonization after biofilm inhibition challenge.

Methods: Resinous liner specimens (Coe-Soft) were prepared and distributed in 3 groups according to the surface treatments: (1) untreated (control); (2) treated with sulfur hexafluoride-based NTP (SF); and (3) treated with hexamethyldisiloxane-based NTP (HMDSO). Read More

A Single Amino Acid Substitution in the Matrix Protein (M51R) of Vesicular Stomatitis New Jersey Virus Impairs Replication in Cultured Porcine Macrophages and Results in Significant Attenuation in Pigs.

Front Microbiol 2020 29;11:1123. Epub 2020 May 29.

Foreign Animal Disease Research Unit, USDA/ARS Plum Island Animal Disease Center, Greenport, NY, United States.

In this study, we explore the virulence of vesicular stomatitis New Jersey virus (VSNJV) in pigs and its potential relationship with the virus's ability to modulate innate responses. For this purpose, we developed a mutant of the highly virulent strain NJ0612NME6, containing a single amino acid substitution in the matrix protein (M51R). The M51R mutant of NJ0612NME6 was unable to suppress the transcription of genes associated with the innate immune response both in primary fetal porcine kidney cells and porcine primary macrophage cultures.

Mucoadhesive in situ forming gel for oral mucositis pain control.

Int J Pharm 2020 Apr 16;580:119238. Epub 2020 Mar 16.

Department of Pharmaceutical Sciences, University of Connecticut, Storrs, CT 06269, United States.

The current first line therapy for oral mucositis pain control is unsatisfactory as it results in only a short duration of modest pain relief. Developing mucoadhesive in situ forming formulations to prolong pain relief is challenging due to their complex physicochemical properties and the unique requirements for oral mucosa application. The objective of this study is to develop a mucoadhesive in situ forming gel to deliver a novel drug molecule, Bupivacaine γ-linoleate (Bup-γL), for prolonged and more potent oral mucositis pain control.
