Although the prevalence of human papillomavirus (HPV)-related oropharyngeal squamous cell carcinoma (OPSCC) is increasing in developed countries and becoming a relevant health issue, the natural history of oral HPV infection is still unclear. Estimating the infection's prevalence in specific populations and identifying risk factors can widen our understanding of its natural history and help to delineate appropriate prevention strategies. This study sought to (i) determine oral HPV prevalence and genotype distribution in a large series of young Italian adults, (ii) validate an oral rinse sampling/storage protocol, and (iii) pinpoint factors associated with oral HPV infection...

Chronic mucocutaneous candidiasis (CMC) is characterized by recurrent or persistent infections affecting the nails, skin and oral and genital mucosae caused by Candida spp., mainly Candida albicans. CMC is an infectious phenotype in patients with inherited or acquired T-cell deficiency. Patients with autosomal-dominant (AD) hyper IgE syndrome (HIES), AD signal transducer and activator of transcription 1 (STAT1) gain-of-function, autosomal-recessive (AR) deficiencies in interleukin (IL)-12 receptor β1 (IL-12Rβ1), IL-12p40, caspase recruitment domain-containing protein 9 (CARD9) or retinoic acid-related orphan receptor γT (RORγT) or AR autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) develop CMC as a major infectious phenotype that is categorized as Syndromic CMC...

In recent years, buccal pouch oral mucosa cells were used as a source of potential biological grafting material in advanced tissue engineering. However, there are several limitations in the process of graft fabrication: donor and recipient patient availability as well as an incomplete knowledge of in vitro procedures related to tissue surgical recovery, in vitro cell culture (IVC) and/or tissue processing in “human somatic cell therapy.” Therefore, the animal model for oral mucosa grafting is still recognized as a source for xenografts and a useful model for biomedical research...

PURPOSE: Nasotracheal intubation is a widely performed technique to facilitate anesthesia induction during oral, dental, and maxillofacial surgeries. The technique poses several risks not encountered with oropharyngeal intubation, most commonly epistaxis due to nasal mucosal abrasion. The purpose of this study was to test whether the use of the Parker Flex-Tip™ (PFT) nasal endotracheal tube (ETT) with a posterior facing bevel reduces epistaxis when compared with the standard nasal RAE ETT with a leftward facing bevel...

BACKGROUND: Oral mucositis occurs in patients undergoing chemoradiation for cancer treatment. It is believed that colonization of ulcerated mucosa by bacteria, fungi and virus results in secondary infections. The effect of chlorhexidine (CHX) on the incidence and severity of oral mucositis in cancer patients was evaluated in this review. METHODS: Studies were limited to randomized placebo-controlled trials. Three databases were searched: MEDLINE (via PubMed), Web of Science and the Cochrane Library up to May 25, 2016...

While investigation of the microbiome on natural oral surfaces has generated a wealth of information, few studies have examined the microbial communities colonizing dentures and their relationship to oral health. To address this knowledge gap, we characterized the bacterial community associated with dentures and remaining teeth in healthy individuals and patients with denture stomatitis. The microbiome compositions of matched denture and tooth plaque samples of 10 healthy individuals and 9 stomatitis patients were determined by 16S rRNA gene pyrosequencing...

The protective efficacy and immunological profiles of chickens immunized with an attenuated Salmonella Enteritidis (SE) constitutively secreting double mutant heat labile enterotoxin (dmLT) were investigated. The dmLT is a detoxified variant of Escherichia coli heat labile toxin and is a potent mucosal adjuvant capable of inducing both humoral and cell-mediated immunity. In this study, four-week-old chickens were inoculated with SE-dmLT strain JOL1641, parental SE strain JOL1087 or phosphate buffered saline control...

The oral mucosa is constantly exposed to an immense amount of microorganisms, while some colonize the various anatomical niches existing in the oral cavity. To deal with such a complex challenge, the oral mucosal immune system must tolerate commensal microorganisms but prevent invasion of pathogens. Such activity is likely to be achieved by a wide range of mechanisms that could be similar or different to those employed by other mucosal tissues. The dental biofilm represents a unique challenge to the mucosal immune system, and inadequate immune responses might lead to periodontal diseases and the associated adverse systemic complications...

The mucosa-draining lymphoid tissue favors differentiation of inducible Foxp3(+) regulatory T cells. Adoptive transfer of T-cell receptor (TCR) transgenic (Tg) T cells is a powerful tool to study antigen-specific regulatory T-cell differentiation in lymphoid tissues in vivo. The kinetics and nature of the T-cell response largely depend on the route of antigen administration and degree of clonal competition. Here, we describe that adoptive transfer of CD4(+) DO11.10 TCR Tg T cells can be used for monitoring Foxp3(+) regulatory T-cell differentiation in the gut-draining lymph nodes...

BACKGROUND: Recurrent aphthous stomatitis (RAS) is the most common chronic oral mucosal condition of the oral cavity. Investigators in clinical trials have evaluated the effectiveness of Chinese patent medicines in the treatment of RAS. However, the results are conflicting rather than conclusive. To evaluate the efficacy and safety of Chinese patent medicines for the treatment of RAS, the authors conducted a systematic review. TYPES OF STUDIES REVIEWED: The authors searched 9 electronic databases to identify randomized controlled trials (RCTs) or potential clinical controlled trials (CCTs), published in any language, in which the investigators compared Chinese patent medicines with vitamin tablets or placebos for the treatment of RAS...
