Abstract
BACKGROUND Dental infections, which are the main cause of tooth loss, are known to be caused by bacteria. However, recent research suggests that other organisms, such as viruses, may also play a role. In this study, we aim to detect the presence of human papillomavirus (HPV)-16 and assess its prevalence in tissues infected with various dental infections, including aggressive and chronic periodontitis, pericoronitis, and periapical infection, as well as healthy gingival tissues, saliva, and gingival crevicular fluid, for comparison. METHODS A cross-sectional study including 124 adult healthy patients presenting with dental infections requiring dental extractions were conducted to assess the prevalence of HPV-16 in saliva, infected, and healthy tissues using quantitative polymerase chain reaction (PCR) tests. Samples were collected and a categorical scale was used for the prevalence. Statistical analyses were performed using Chi-square for the prevalence of HPV-16. RESULTS Among the HPV-16-positive PCR cases, the prevalence of HPV-16 was highest in periapical infection tissues as compared to chronic periodontitis, aggressive periodontitis, pericoronitis, and control tissues. CONCLUSION The prevalence of HPV-16 in periapical infection samples was the highest among the studied dental infection samples. Thus, a primary conclusion can be drawn about the presence of an association between HPV-16 and the occurrence of periapical infection.

Abstract
Simple Summary Human papillomavirus (HPV) infection is a sexually transmitted disease with high prevalence worldwide. Although most HPV infections do not lead to cancer, some HPV types are correlated with the majority of cervical cancers, and with some anogenital and oropharyngeal cancers. Moreover, enzymes known as proteases play an essential role in the pathogenic process in HPV-induced carcinogenesis. This review highlights the role of proteases and recent epidemiological data regarding HPV-dependent carcinogenesis. Abstract Persistent infection with Human papillomavirus (HPV) is the main etiologic factor for pre-malignant and malignant cervical lesions. Moreover, HPV is also associated with oropharynx and other anogenital carcinomas. Cancer-causing HPV viruses classified as group 1 carcinogens include 12 HPV types, with HPV 16 and 18 being the most prevalent. High-risk HPVs express two oncoproteins, E6 and E7, the products of which are responsible for the inhibition of p53 and pRB proteins, respectively, in human keratinocytes and cellular immortalization. p53 and pRB are pleiotropic proteins that regulate the activity of several signaling pathways and gene expression. Among the important factors that are augmented in HPV-mediated carcinogenesis, proteases not only control processes involved in cellular carcinogenesis but also control the microenvironment. For instance, genetic polymorphisms of matrix metalloproteinase 1 (MMP-1) are associated with carcinoma invasiveness. Similarly, the serine protease inhibitors hepatocyte growth factor activator inhibitor-1 (HAI-1) and -2 (HAI-2) have been identified as prognostic markers for HPV-dependent cervical carcinomas. This review highlights the most crucial mechanisms involved in HPV-dependent carcinogenesis, and includes a section on the proteolytic cascades that are important for the progression of this disease and their impact on patient health, treatment, and survival.

Abstract
OBJECTIVE To report the signalment, staging, surgical treatment, and survival time of juvenile dogs treated surgically for oral squamous cell carcinoma (OSCC). STUDY DESIGN Retrospective study. ANIMALS OR SAMPLE POPULATION Twenty-five dogs, <2 years of age with OSCC treated with surgery. METHODS Cases were solicited from the Veterinary Society of Surgical Oncology. Data retrieved included sex, breed, age, weight, clinical signs, tumor location, preoperative diagnostics and staging, histopathological diagnosis with margin evaluation, disease-free interval, and date and cause of death. A minimum follow-up time of 3 months was required for inclusion. RESULTS Eighteen dogs were <12 months of age, and seven were <24 months. Various breeds were represented, with a mean body weight of 22.3 ± 14.4 kg. No dogs had evidence of metastatic disease prior to surgery. All dogs underwent partial maxillectomy or mandibulectomy. Histological margins were complete in 24 dogs and incomplete in one. No dogs had evidence of metastatic disease or tumor recurrence. The median follow-up time was 1556 days (92 to 4234 days). All dogs were alive at the last follow-up except for one documented death, due to dilated cardiomyopathy. Median disease-specific survival time was not reached. CONCLUSION The prognosis after wide surgical excision of OSCC in juvenile dogs was excellent. CLINICAL SIGNIFICANCE OSCC in juvenile dogs can be effectively treated with surgery alone.

Abstract
OBJECTIVE This study aimed to evaluate the presence of human papillomavirus (HPV) and Epstein-Barr virus (EBV) and the expression of p53, p16, E-cadherin, COX-2, MLH1, and MYC in oral squamous cell carcinoma (OSCC). MATERIALS AND METHODS One hundred OSCC specimens were submitted to in situ hybridization for HPV and EBV, and immunohistochemistry for detection of the human proteins. RESULTS Thirty-one cases showed HPV in tumor tissue. EBV was not detected in any case investigated. The HPV(+) group demonstrated an increase of staining scores for nuclear p16 (p = .047), cytoplasmic MYC (p = .002), while a decrease for nuclear MLH1 (p = .048), suggesting that HPV may upregulate the expression of the first two proteins and down-regulate the latter. CONCLUSION Our findings reinforce the hypothesis of the HPV-related oral carcinogenesis involving the expression of p16 and MYC, and MLH1 suppression. Exclusively cytoplasmic stainings for p16, MLH1, and MYC were also associated with more advanced tumors. Finally, in view of the lack of studies correlating the HPV or EBV infection to the expression of oncoproteins, more researches assessing a broader panel of markers and employing different approaches are still necessary in order to understand the role of these viruses as well as the molecular mechanisms involved in the development and progression of oral carcinomas.

Abstract
Objective: The aim of our retrospective study is to compare the long-term recurrence rate of the benign oral squamous papilloma (OSP) with different laser-assisted treatments and conventional procedures (use of scalpels) aiming to suggest the most suitable surgical protocol showing the lowest recurrence rate. Background: A retrospective multicenter DATA collection between 1985 and 2019 covering 781 OSP cases concerning different surgical protocols used for the treatment of OSP was done and included the use of different laser wavelengths [neodymium-doped yttrium-aluminum-garnet (Nd:YAG), carbon dioxide (CO2), and Diode 980 nm] and the conventional surgeries using the scalpel. The age, sex, and the oral location of the OSP were noted. Methods: Three different surgical protocols were selected in our study: protocol 1 regrouped surgical procedures performing the excision of OSP with an in-depth safety margin of 1 mm and just at the base of the tumor with reduced excision of the grossly normal marginal mucosa around the tumor (0-1 mm). Protocol 2 and 3 were similar to protocol 1, but with an additional excision of 1-2 mm and ≥3 mm of the grossly normal marginal mucosa, respectively, for group 2 and 3. All laser-treated OSP wounds were left without sutures. In the conventionally treated OSP, sutures were regularly performed. Follow-up was done after 15 days and at 1, 6, and 18 months. The three included wavelengths were Nd:YAG (1064 nm), CO2 laser (10,600 nm), and diode laser (980 nm). Results: After 18 months of follow-up, the highest success rate was obtained with protocol 3 (100% with Nd:YAG, 99% with CO2, 98.4% with diode, and 99% with the scalpel), which was significantly higher than the values of protocol 2 (96.6% with Nd:YAG, 91% with CO2, 96% with diode, and 95% with the scalpel) and the protocol 1 (38% with Nd:YAG, 29% with CO2, 33% with diode, and 30% with the scalpel). The oral locations of OSP were 30% on palates, 30% on the tongue, 16% on cheek, 14% on lips, and 10% on other locations. Conclusions: The lowest recurrence rate was observed when a minimum of three millimeters (≥3 mm) of grossly normal aspect mucosa around the OSP was included in the excisions. The laser wavelengths and the use of scalpel did not show any significant difference in terms of recurrence.

Abstract
OBJECTIVES To estimate the association of human papillomavirus (HPV) infection with oral lichen planus (OLP) and oral leukoplakia (OLK), and determine risk cofactors. STUDY DESIGN Seven databases were searched for case-control or cross-sectional studies of OLP and OLK with healthy controls, published between 1976 and 2020. The Meta package of R software was applied to calculate the pooled odds ratios (OR) and 95% confidence interval (CI). RESULTS Thirty-six articles were finally included. OLP and OLK cases had a higher association with HPV infection than controls (OLP: OR: 4.91, 95% CI: 2.76-8.72; OLK: OR: 2.51, 95% CI: 1.55-4.07). In subgroup analyses, the OR of HPV infection was higher with erosive lesions than with nonerosive lesions (OLP: OR: 5.36 and 3.47, respectively; OLK: OR: 3.34 and 3.21, respectively). Oral lesions were more strongly associated with HPV16/18 than with HPV6/11 (OLP: OR: 7.84 and 1.42, respectively; OLK: OR: 6.05 and 1.87, respectively) and varied by geographic region (OLP: OR: 4.01-7.02; OLK: OR: 1.46-27.13). CONCLUSIONS Oral HPV infection, particularly infection with HPV 16/18, was strongly associated with OLP and OLK. Risk cofactors included erosive lesions and geographic region.

Abstract
The purpose of this systematic review and meta-analysis was to estimate the overall and type-specific prevalence of human papillomavirus (HPV) DNA in oral epithelial dysplasia and assess p16INK4a overexpression in relation to HPV-status. A systematic literature search identified 31 eligible studies (832 cases) evaluating the presence of HPV DNA in oral epithelial dysplasia cases by PCR. Of these, six studies evaluated p16INK4a overexpression in relation to HPV-status. The overall pooled prevalence of HPV DNA in oral epithelial dysplasia was 27.2% (95% CI: 17.6-38.1). We observed substantial interstudy heterogeneity, which could not be explained by differences in continent, tissue type, or severity of epithelial dysplasia. HPV16 was the predominant genotype detected. Moreover, 62.2% of HPV positive and 17.8% of HPV negative oral epithelial dysplasia samples stained intensively positive for p16INK4a . This meta-analysis found that 27% of oral epithelial dysplasia harbor HPV DNA. Whether this represents a transient infection or has a carcinogenic role is unknown.

Human papillomavirus (HPV) can establish productive infection in dysplastic oral mucosa, but HPV status is poorly predicted by histological features and p16 expression.

Abstract
AIMS Previous studies have reported the presence of high-risk human papillomavirus (HR-HPV) in a subset of dysplastic oral epithelial lesions. Many cases show a histological spectrum of atypia similar to that seen in non-human papillomavirus (HPV) severe epithelial dysplasia, but some studies have suggested that HPV status can be inferred on the basis of histological features. We aimed to assess the utility of such histological features and p16 as surrogate markers of HPV infection in a retrospective cohort of 33 cases of severe epithelial dysplasia, with matched clinicopathological data and histological features. METHODS AND RESULTS Tissue sections were assessed for the expression of p16, minichromosome maintenance 2, HPV E4 and HPV L1 by the use of immunohistochemistry. HPV16/18 E6 and E7 expression was assessed by the use of RNA in-situ hybridisation (RNAScope). In the cohort, 18.2% of cases (6/33) were HR-HPV-positive, with no age/gender differences between the HPV-positive and HPV-negative groups. HPV E4 and HPV L1 were expressed in surface keratinocytes in four of six (66%) HPV-positive cases, indicative of productive HPV infection. Lack of p16 expression was predictive of HPV-negative status, but sensitivity and specificity varied according to the cut-off. Histologically, the presence of karyorrhectic nuclei and abnormal mitotic figures was higher in HPV-positive lesions (P < 0.05), but the predictive specificity and sensitivity were suboptimal (sensitivity, 0.75; specificity, 0.52). CONCLUSIONS This study demonstrates, for the first time, that a minority of severely dysplastic oral lesions harbour productive, biologically relevant HPV infection. Consideration should be given to the specific assessment of HPV status in severe epithelial dysplasia cases, as both p16 status and the presence of karyorrhectic cells are poor predictive markers of HPV status.

Extracapsular extension of neck nodes and absence of human papillomavirus 16-DNA are predictors of impaired survival in p16-positive oropharyngeal squamous cell carcinoma. Cancer 2020; 126:1856-1872. [PMID: 32032442 DOI: 10.1002/cncr.32667] [Citation(s) in RCA: 27] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2019] [Revised: 10/25/2019] [Accepted: 11/11/2019] [Indexed: 12/13/2022]
Abstract
BACKGROUND Human papillomavirus (HPV)-driven oropharyngeal squamous cell carcinomas (OPSCCs) demonstrate superior outcome compared with HPV-negative OPSCCs. The eighth edition of the American Joint Committee on Cancer/Union for International Cancer Control (AJCC/UICC) tumor, lymph node, metastasis (TNM) classification (TNM 2017) modifies OPSCC staging based on p16 positivity as a surrogate for HPV-driven disease. In p16-negative OPSCCs, lymph node (N) categories include extracapsular/extranodal extension (ECE); and, in p16-positive OPSCCs, N categories are based on the number of positive neck lymph nodes omitting ECE status. The objective of the current study was to assess the prognostic impact of positive ECE status and the detection of HPV16 DNA in patients with p16-positive OPSCC. METHODS In a cohort of 92 patients with p16-positive, lymph node (N)-positive (stage III-IVB) OPSCC who underwent surgery and neck dissection, allowing for a pathologic examination of positive lymph nodes, 66 of 92 patients (71.4%) were p16-positive/HPV16 DNA-positive, 62 of 92 (67%) were ECE-positive, and 45 of 62 (72.6%) were ECE-positive, p16-positive, and HPV16 DNA-positive. Differences in outcome were assessed using Kaplan-Meier plots and Cox proportional hazard regression (CoxR) for tumor-specific survival and overall survival (OS). RESULTS The mean numbers of positive lymph nodes in ECE-positive patients (5.0 positive lymph nodes; 95% CI, 3.8-6.4 positive lymph nodes) and ECE-negative patients (2.4 positive lymph nodes; 95% CI, 1.8-2.9 positive lymph nodes) were different (P = .0007). ECE affected OS and tumor-specific survival in p16-positive patients (P = .007 and P = .047, respectively) and in p16-positive/HPV16 DNA-positive patients (P = .013 and P = .026, respectively). Related to the unequal distributions of ECE-positive/HPV16 DNA-negative tumors, the TNM 2017 failed to discriminate OS in patients with UICC stage I, II, and III disease (mean OS, 54.5, 73.4, and 45 months, respectively; median OS, 64.7 months, not reached, and 41.1 months, respectively). According to a univariate CoxR, the presence of ECE predicted impaired OS in patients with p16-positive OPSCC (hazard ratio, 3.40; 95% CI, 1.17-9.89; P = .025) and even greater impaired OS in those with p16-positive/HPV16 DNA-positive OPSCC (HR, 8.64; 95% CI, 1.12-66.40; P = .038). Multivariate CoxR confirmed ECE and HPV16 DNA detection as independent predictors. CONCLUSIONS ECE and HPV16 DNA status should be included in the prognostic staging of patients with p16-positive OPSCC because several lines of evidence demonstrate their impact on survival.

Abstract
Oral epithelial dysplasia is a spectrum of architectural and cytological epithelial changes caused by accumulation of genetic changes, and is associated with an increased risk of progression to squamous cell carcinoma. It is a microscopic diagnosis of immense clinical importance. The initial reports of oral potentially malignant disorders with oral epithelial dysplasia transforming to oral cancer helped in understanding the nature of oral malignancies. Since then, clinical studies on oral potentially malignant disorders have combined microscopic findings of oral epithelial dysplasia to assess the malignant transformation potential of different grades of epithelial dysplasia. A significant amount of scientific literature has amassed on oral epithelial dysplasia relating to aspects of its diagnosis and management. However, the evidence base is weak as a result of the significant variability of published research. Poorly described study methods, variability in different oral epithelial dysplasia grading systems, inter- and intra-examiner variability causing issues of reliability, inadequate sample size, and inconsistent durations of follow-up are some of the methodological issues contributing to the failure to provide dependable information. Randomized clinical trials on the malignant transformation potential of oral epithelial dysplasia and its treatment outcomes are limited. This comprehensive literature review on oral epithelial dysplasia summarizes the scientific knowledge published in the scientific literature in English since its first description. The historical development, etiological factors, grading systems, diagnostic criteria, assessment of risk factors and prevention of malignant transformation, management principles of different grades of oral epithelial dysplasia (surgical and nonsurgical), recommendations on follow-up, and prognostic indicators are discussed in detail.

Abstract
BACKGROUND Oral papillomas and verruca vulgaris have been associated with human papillomavirus (HPV) infection. However, approximately half of these have remained HPV-negative when tested for mucosal HPV genotypes. In this study, we evaluated presence of α-, β-, and γ-HPVs in benign papillary and verrucous lesions. METHODS Eighty-three clinical lesions with suspected HPV etiology were analyzed for HPV types of genus α (n = 24), β (n = 46), and γ (n = 52). Immunohistochemistry was used for p16 as a possible surrogate marker of high-risk HPV, accompanied by Ki-67 proliferation marker. RESULTS Altogether, α-HPVs were detected in 6.4%, β-HPVs in 2.4%, and γ-HPV in 4.8%. The following genotypes were identified: HPV6, 8, 11, 16, 22, 161, and 170. Neither Ki-67 nor p16 positivity alone were associated with HPV but combined staining showed significant inverse association (P = .042). CONCLUSION HPV infection is found only in a minority of benign verrucous and papillary oral lesions, with the predominance of α-HPVs. LEVEL OF EVIDENCE 4.

Human papillomavirus in premalignant oral lesions: No evidence of association in a Spanish cohort. PLoS One 2019; 14:e0210070.

Abstract
Background Human papillomavirus (HPV) is the cause of a fraction of head and neck squamous cell carcinoma. Although this relation is well-known, it is still not clear the role of HPV in premalignant oral lesions such as oral lichen planus (OLP) and dysplasia. We aimed to evaluate the HPV-DNA prevalence and type distribution in a set of oral biopsies obtained from patients diagnosed with OLP and dysplasia, as well as the role of HPV in these lesions. Methods A retrospective cohort of all premalignant oral lesions consecutively diagnosed from March 30th 1995 to May 21st 2014 at Hospital of Bellvitge and Odontological University Hospital of Bellvitge was identified and classified in four groups: OLP (groups 1 and 2) and dysplasias (groups 3 and 4) that progressed or not to invasive cancer during follow-up. A random selection targeting 25 cases was aimed to be performed for each group. All selected cases were subjected to pathological evaluation, DNA quality control and HPV-DNA detection. HPV-DNA positive samples were further subject to p16INK4a analysis. Results A total of 83 cases yielded a valid HPV-DNA result. From those, 7 and 34 cases were OLP that progressed or not to invasive cancer during follow-up, whereas 24 and 18 cases were displasias that progressed or not to invasive cancer during follow-up, respectively. HPV-DNA was detected in 4 samples (3 dysplastic lesions and 1 OLP). Two samples were HPV16 positive (2%), 1 sample HPV18 positive (1%) and 1 sample (1%) was HPV indeterminate. Two out of four HPV-DNA positive cases had high p16INK4a expression and none of the HPV positive cases progressed to invasive cancer during long-term follow-up. Conclusions We found a low HPV-DNA attributable fraction in premalignant lesions of the oral cavity, suggesting that HPV is unlikely to play a significant role in oral carcinogenesis in our setting.

Abstract
The aim of this study was to investigate the association between fine particulate matter 2.5 (PM2.5) and oral cancer among Taiwanese men. Four linked data sources including the Taiwan Cancer Registry, Adult Preventive Medical Services Database, National Health Insurance Research Database, and Air Quality Monitoring Database were used. Concentrations of sulfur dioxide, carbon monoxide, ozone, NOx (nitrogen monoxide and nitrogen dioxide), coarse particulate matter (PM10-2.5) and PM2.5 in 2009 were assessed in quartiles. A total of 482 659 men aged 40 years and above were included in the analysis. Logistic regression was used to examine the association between PM2.5 and oral cancer diagnosed from 2012 to 2013. After adjusting for potential confounders, the ORs of oral cancer were 0.91 (95% CI 0.75 to 1.11) for 26.74≤PM2.5<32.37, 1.01 (95% CI 0.84 to 1.20) for 32.37≤PM2.5<40.37 µg/m3 and 1.43 (95% CI 1.17 to 1.74) for PM2.5≥40.37 µg/m3 compared with PM2.5<26.74 µg/m3. In this study, there was an increased risk of oral cancer among Taiwanese men who were exposed to higher concentrations of PM2.5.

Abstract
Objective: To determine the prevalence of human papillomavirus (HPV) DNA in oral squamous cell carcinoma (OSCC). Methods: A total of 88 OSCC specimens collected between 2006 and 2013 were available for the study. DNA was extracted using formalin-fixed, paraffin-embedded specimens and analysed for the presence of 18 HPV genotypes using a nested polymerase chain reaction using consensus forward primer (GP-E6-3F) and two consensus back primers (GP-E7-5B and GP-E7-6B). Plasmid DNA of HPV 16 and 18 was used as positive controls. Results: HPV DNA was detected in 3 of the 88 samples, a prevalence of 3.4%. Genotypes detected were 16, 18 and 52. Conclusion: The overall prevalence of HPV DNA was 3.4%. Only high-risk genotypes were detected. This low prevalence of high-risk types of HPV suggests that the HPV virus may not have a significant role in the development of oral cancers in Ghana, unlike higher rates described elsewhere in the world, especially in Western countries. Surveillance of future prevalence of HPV and attention to other major risk factors is warranted.

Abstract
Cigarette smoking has been associated with both the diagnosis of bacterial vaginosis (BV) and a vaginal microbiota lacking protective Lactobacillus spp. As the mechanism linking smoking with vaginal microbiota and BV is unclear, we sought to compare the vaginal metabolomes of smokers and non-smokers (17 smokers/19 non-smokers). Metabolomic profiles were determined by gas and liquid chromatography mass spectrometry in a cross-sectional study. Analysis of the 16S rRNA gene populations revealed samples clustered into three community state types (CSTs) ---- CST-I (L. crispatus-dominated), CST-III (L. iners-dominated) or CST-IV (low-Lactobacillus). We identified 607 metabolites, including 12 that differed significantly (q-value < 0.05) between smokers and non-smokers. Nicotine, and the breakdown metabolites cotinine and hydroxycotinine were substantially higher in smokers, as expected. Among women categorized to CST-IV, biogenic amines, including agmatine, cadaverine, putrescine, tryptamine and tyramine were substantially higher in smokers, while dipeptides were lower in smokers. These biogenic amines are known to affect the virulence of infective pathogens and contribute to vaginal malodor. Our data suggest that cigarette smoking is associated with differences in important vaginal metabolites, and women who smoke, and particularly women who are also depauperate for Lactobacillus spp., may have increased susceptibilities to urogenital infections and increased malodor.

Abstract
Background: Recently, associations of the human papillomavirus (HPV) with head and neck cancer have become well established. Of particular concern, the severity and pathological outcomes of squamous cell carcinomas are remarkably affected by the genotypes of HPV present in such lesions. This study was conducted to investigate the occurrence of HPV genotypes, particularly high risk 16 and 18, among oral and laryngeal squamous cell carcinomas in Jordan. Methods: During the period of May 2015 to March 2016, we evaluated a total of 108 paraffin-embedded tissue samples, histologically confirmed as SCC, of both oral and laryngeal tumors for the presence of HPV DNA. DNA was extracted using a Zymogen commercial kit. HPV genotypes were detected by nested PCR using consensus primers followed by primer-specific PCR for HPV-16 and HPV-18 genotypes. The genotypes were confirmed by DNA sequencing methods. Results: Sixteen samples were positive for HPV DNA (14.8%) with higher rates in oral tumors compared to their laryngeal counterparts (20% and 6% respectively). The HPV-16 genotype predominated, being detected in 81.3% of the cases as a single infection and in 18.7% in combination with HPV-18. A significant association between the anatomical location and the HPV-16 genotype was observed (p < 0.05). In contrast, no significant associations could be established with tumor grade and gender or age. Conclusions: A relatively high rate of high-risk HPV genotypes, especially HPV 16, is evident in head and neck cancers SCCs in Jordan. Genotyping of HPV might be of considerable value for evaluation of progression.

Abstract
Our objective was to compare archived tissue biopsy samples from the oral cavity and oropharynx, in terms of human papillomavirus (HPV) 16 infection. We used Taqman real-time PCR assay to detect HPV16 in 121 archived biopsy samples from the oral cavity and 100 samples from the oropharynx. Among patients with oral cavity cancer (OCC), 9% (6/65) had HPV16 infection which was significantly less than those with oropharyngeal cancer (OPC) where 79% (39/50) were HPV16 positive (P < 0.001). Our results demonstrated a significant difference between genders where males had a seven times higher chance of having HPV16 infection (P < 0.001). Viral load variation between each group was demonstrated. The median viral load in OPC was similar in OCC cases, but cancer samples were significantly higher than in non-cancer cases (oral cavity samples P = 0.015; oropharynx samples P = 0.09). From our results, we conclude that there is a significant difference in HPV16 detection between OCC and OPC, and HPV16 differs greatly between male and female cancer patients.

Abstract
Normal somatic cells terminate their replicative life span through a pathway leading to cellular senescence, which is triggered by activation of p53 and/or pRb in response to critically shortened telomere DNA. Potentially neoplastic cells must first overcome the senescence checkpoint mechanisms and subsequently activate telomerase to propagate indefinitely. Although telomerase activation is closely associated with cellular immortality, telomerase alone is not sufficient to warrant tumorigenicity. Environmental factors, including chemical carcinogens and viral infection, often contribute to aberrant changes leading to tumorigenic conversion of normal cells. Of particular importance in oral cancer development are tobacco-related chemical carcinogens and human papillomavirus (HPV) infection. To describe the molecular mechanisms by which these environmental factors facilitate the genesis of oral cancer, we first established an in vitro multistep oral carcinogenesis model by sequential exposure of normal human oral keratinocytes (NHOK) to "high risk" HPV and chemical carcinogens. Upon introduction of the HPV genome, the cells bypassed the senescence checkpoint and entered into an extended, but not immortal, life span during which telomere DNA continued to shorten. In a few immortal clones surviving beyond the crisis, we found a marked elevation of telomerase activity and stabilization of telomere length. Furthermore, the E6 and E7 oncoproteins of "high risk" HPV disrupted the cell cycle control and DNA repair in immortalized HOK, and enhanced mutation frequency resulting from genomic instability. However, HPV infection alone failed to give rise to a tumorigenic cell population, which required further exposure to chemical carcinogens in addition to HPV infection. Analysis of the data presented suggests that oral carcinogenesis is a series of discrete genetic alterations that result from a continued genotoxic challenge by environmental risk factors. Our in vitro model may be useful for investigators with interest in furthering our understanding of oral carcinogenesis.

Abstract
OBJECTIVE The aim of the study was to assess the clinicopathological characteristics of patients with verrucous carcinoma (VC) of the vulva. MATERIALS AND METHODS We reviewed data on the age, disease course, clinical manifestation, pathologic diagnosis, treatment, and follow-up of patients with vulvar VC who were treated at Tianjin Medical University General Hospital and cases that were reported in the Chinese and English literature during the past 20 years. RESULTS Six cases were identified in Tianjin Medical University General Hospital, the mean age of patients was 55 years, and their mean disease course was 26 months. Primary symptoms were exophytic neoplasm with pruritus and/or pain. Surgical treatment included wide local excision, simple vulvectomy, and radical vulvectomy with or without lymph node dissection in the groin. Vulvar VC occurred simultaneously with vulvar intraepithelial neoplasia in 2 cases and well-differentiated squamous cell carcinoma in 2 cases. The mean follow-up was 16.8 months with no recurrence in those 6 cases. During the 20-year period, 20 and 41 cases were reported in Chinese and English literature, respectively. Three cases were misdiagnosed with giant condyloma acuminatum in China. One case (1/20) was reported with coexistent squamous carcinoma in Chinese literature and 8 cases (8/41) in the English literature. The recurrence rate was 12.5% (2/19) and 17.5% (7/40) in Chinese and English literature, respectively. CONCLUSIONS Vulvar VC is a distinct type of slow-growing, nonmetastatic tumor with unclear etiology. These tumors should be distinguished from giant condyloma acuminatum and well-differentiated squamous cell carcinoma. Surgery is the most effective treatment.

Abstract
INTRODUCTION Over the last few years, oral and pharyngeal signs and symptoms due to oral sex have increased significantly. However, no review articles related to this subject have been found in the medical literature. The objective of our study was to identify otorhinolaryngological manifestations associated with orogenital/oroanal contact, both in adults and children, in the context of consensual sex or sexual abuse. METHODS We performed a review of the medical literature on otorhinolaryngological pathology associated with oral sex published in the last 20 years in the PubMed database. RESULTS Otorhinolaryngological manifestations secondary to oral sex practice in adults can be infectious, tumoral or secondary to trauma. The more common signs and symptoms found in the literature were human papillomavirus infection (above all, condyloma acuminata and papilloma/condyloma), oral or pharyngeal syphilis, gonococcal pharyngitis, herpes simplex virus infection and pharyngitis from Chlamydia trachomatis. The incidence of human papillomavirus -induced oropharyngeal carcinoma has dramatically increased. In children past the neonatal period, the presence of condyloma acuminatus, syphilis, gonorrhoea or palatal ecchymosis (the last one, unless justified by other causes) should make us suspect sexual abuse. CONCLUSIONS Sexual habits have changed in the last decades, resulting in the appearance of otorhinolaryngological pathology that was rarely seen previously. For this reason, it is important for primary care physicians to have knowledge about the subject to perform correct diagnosis and posterior treatment. Some sexual abuse cases in children may also be suspected based on the knowledge of the characteristic oropharyngeal manifestations secondary to them.

Abstract
The aim of this study was to evaluate the use of GP5+/6+, MY09/11 and PGMY09/11 primer sets for the detection of human papillomavirus (HPV) DNA by single step polymerase chain reaction (PCR) and nested PCR in formalin-fixed and paraffin-embedded (FFPE) tissues from oral squamous cell carcinomas (OSCCs). DNA extracted from FFPE tissues were tested for amplification of the human beta globin gene with PCO3/4 primers. Positive samples for this gene were tested for HPV DNA using single step PCR with GP5+/6+, MY09/11 and PGMY09/11 primer sets. All negative samples at single step PCR with MY09/11 and PGMY09/11 were subjected to a further PCR with GP5+/6+ primers using the non-amplified product in the previously reactions (nested PCR) as samples. Among 26 samples, 23 were positive for the human beta globin gene and were considered viable for HPV DNA detection by PCR. Single step PCR with GP5+/6+ and MY09/11 primers and MY/GP+ nested PCR did not amplify HPV DNA in any samples. PGMY09/11 primers detected HPV DNA in 13.0% of OSCC cases and this rate was raise to 17.4% with the use of PGMY/GP+ nested PCR. According to our results the PGMY/GP+ nested PCR is the most appropriate primer set for the detection of HPV DNA using FFPE samples from OSCC.

Abstract
BACKGROUND The role of human papillomavirus (HPV) infection in oropharyngeal cancer (SCC) is well established. The annual incidence of oropharyngeal SCC in Israel is considerably lower than that in the United States. The purpose of this study was to assess the rate of HPV-related oropharyngeal SCC in Israel. METHODS The cohort included patients with oropharyngeal SCC who were treated during 1999 to 2011 in Israel. HPV typing was carried out using reverse hybridization and immunohistochemistry. RESULTS Of the 74 patients analyzed, 25 (33.7%) had detectable HPV DNA. Patients in the HPV-positive group tended to be younger, with a higher rate of nodal metastases, and no history of smoking (p < .02). CONCLUSION This study demonstrated a rate of HPV-related oropharyngeal SCC in Israel as approximately 3-fold lower than in Western countries. Low exposure to HPV-16, a lower rate of transformation, to cancer or protective genetic factors may contribute to the lower rate of oropharyngeal SCC in Israel. © 2015 Wiley Periodicals, Inc.

Abstract
The prevalence of oral squamous cell carcinoma (OSCC) has significantly increased over decades in several countries and human papilloma virus (HPV) has been indicated as one of the underlying causes. This suggests that HPV plays a role in the early stages of carcinogenesis but is not a requisite for the maintenance and progression of malignant state. p53 is a tumor suppressor gene that checks the cell and promotes apoptosis and cell repair that can be deactivated by mutations and a viral interaction leading to cancer and individuals with particular polymorphic variant of p53 is more susceptible to HPV-induced carcinogenesis. The present study has been carried out to detect and correlate p53 polymorphism/mutation, HPV DNA in the biopsy samples of oral cancer patients who had tobacco habits.

Abstract
There is increasing evidence of a causal association between human papillomavirus (HPV) and oral squamous cell carcinoma (OSCC). Several studies have shown that HPV is associated with increased risk of oral cancer independent of exposure to tobacco and alcohol. The association is valid for HPVs 16 and 18, which generally are considered high risk types, because they have been detected in oral dysplastic lesions and cancers. We determined the baseline prevalence of HPVs 16 and 18 in normal oral mucosa of individuals with and without tobacco habit. PCR was used for DNA collected by oral smears to detect HPV 16/18 DNA in normal oral mucosa of 60 healthy individuals who were assigned to two groups of 30 subjects each. One group had a tobacco habit, the other did not. The tobacco user group comprised individuals who were tobacco chewers only. Sixty-five percent of individuals were positive for HPV 16/18 DNA, but HPV 16/18 positivity was less in individuals with tobacco habit than in those without tobacco habit. No significant association was found between the presence of HPVs and gender, age or duration of chewing habit, or between groups with and without a tobacco habit. We propose that HPVs16 and 18 commonly are present in normal oral mucosa and emphasize the importance of distinguishing clinical, subclinical and latent HPV infections when investigating HPVs and OSCC.

Abstract
OBJECTIVES To evaluate the role of HPV in oral carcinogenesis, we examined the prevalence of HPV in malignant, potentially malignant and normal oral epithelium and studied the relation of HPV prevalence with other factors obtained from the patient's records. MATERIALS AND METHODS Our material consisted of 291 tissue specimens from 258 individuals. From every individual formalin fixed and paraffin embedded tissues were examined by nested Polymerase Chain Reaction (NPCR) for the detection of HPV DNA and by immunohistochemistry (IHC) for the in situ detection of HPV L1 protein. Positive PCR products were sequenced in order to type HPVs. Also 33 fresh tissues were obtained, fixed and used to detect HPV particles by transitional electron microscopy (TEM). RESULTS HPV was detected in 32.9% of the tissue specimens by NPCR, in 4.7% by immunohistochemistry and in 28.1% by TEM. In detail, by nested PCR HPV L1 DNA was detected in 40% of normal tissues, 40% of fibromas, 35.8% of non-dysplastic leukoplakias, 31.6% of dysplastic leukoplakias and 22.2% of oral squamous cell carcinomas. The HPV viral load of 96.5% of the samples was very low (1 viral copy per 10(2)-10(4) cells). HPV16 prevails in all histological groups in 89-100%. CONCLUSION We conclude that HPV does not seem, from the specific sample examined, to play a substantial role in oral carcinogenesis. However, it cannot be excluded that HPV could be involved in oral carcinogenesis only in cases with high viral load or at early stages of carcinogenesis possibly through the hit-and-run mechanism.

Abstract
Abnormal chromosome number, or aneuploidy, is a common feature of human solid tumors, including oral cancer. Deregulated spindle assembly checkpoint (SAC) is thought as one of the mechanisms that drive aneuploidy. In normal cells, SAC prevents anaphase onset until all chromosomes are correctly aligned at the metaphase plate thereby ensuring genomic stability. Significantly, the activity of this checkpoint is compromised in many cancers. While mutations are rather rare, many tumors show altered expression levels of SAC components. Genomic alterations such as aneuploidy indicate a high risk of oral cancer and cancer-related mortality, and the molecular basis of these alterations is largely unknown. Yet, our knowledge on the status of SAC components in oral cancer remains sparse. In this review, we address the state of our knowledge regarding the SAC defects and the underlying molecular mechanisms in oral cancer, and discuss their therapeutic relevance, focusing our analysis on the core components of SAC and its target Cdc20.

Abstract
UNLABELLED Human papillomavirus (HPV) causes a number of neoplastic diseases in humans. Here, we show a complex normal HPV community in a cohort of 103 healthy human subjects, by metagenomics analysis of the shotgun sequencing data generated from the NIH Human Microbiome Project. The overall HPV prevalence was 68.9% and was highest in the skin (61.3%), followed by the vagina (41.5%), mouth (30%), and gut (17.3%). Of the 109 HPV types as well as additional unclassified types detected, most were undetectable by the widely used commercial kits targeting the vaginal/cervical HPV types. These HPVs likely represent true HPV infections rather than transitory exposure because of strong organ tropism and persistence of the same HPV types in repeat samples. Coexistence of multiple HPV types was found in 48.1% of the HPV-positive samples. Networking between HPV types, cooccurrence or exclusion, was detected in vaginal and skin samples. Large contigs assembled from short HPV reads were obtained from several samples, confirming their genuine HPV origin. This first large-scale survey of HPV using a shotgun sequencing approach yielded a comprehensive map of HPV infections among different body sites of healthy human subjects. IMPORTANCE This nonbiased survey indicates that the HPV community in healthy humans is much more complex than previously defined by widely used kits that are target selective for only a few high- and low-risk HPV types for cervical cancer. The importance of nononcogenic viruses in a mixed HPV infection could be for stimulating or inhibiting a coexisting oncogenic virus via viral interference or immune cross-reaction. Knowledge gained from this study will be helpful to guide the designing of epidemiological and clinical studies in the future to determine the impact of nononcogenic HPV types on the outcome of HPV infections.

Abstract
Oral cancer is one of the most common cancers and it constitutes a major health problem particularly in developing countries. Oral squamous cell carcinoma (OSCC) represents the most frequent of all oral neoplasms. Several risk factors have been well characterized to be associated with OSCC with substantial evidences. The etiology of OSCC is complex and involves many factors. The most clearly defined potential factors are smoking and alcohol, which substantially increase the risk of OSCC. However, despite this clear association, a substantial proportion of patients develop OSCC without exposure to them, emphasizing the role of other risk factors such as genetic susceptibility and oncogenic viruses. Some viruses are strongly associated with OSCC while the association of others is less frequent and may depend on cofactors for their carcinogenic effects. Therefore, the exact role of viruses must be evaluated with care in order to improve the diagnosis and treatment of OSCC. Although a viral association within a subset of OSCC has been shown, the molecular and histopathological characteristics of these tumors have yet to be clearly defined.

Abstract
Objectives Papilloma frequently develops as a benign tumor of the head and neck area, but its potential for malignant transformation has yet to be studied. This study aims to provide basic information for papillomas using the immunohistochemical staining of matrix metalloproteinase 2 (MMP-2) and human papilloma virus (HPV) 16 and 18. Materials and Methods To evaluate the malignant transformation of papillomas, the selected tissue samples were serially diagnosed with pre-cancerous papilloma (with epithelial dysplasia, pseudo-epitheliomatous hyperplasia) or malignant lesion (squamous cell carcinoma, SCC) after the first diagnosis (squamous papilloma, inverted papilloma). The selected tissues were stained with an antibody to MMP-2 and HPV 16-E7, HPV 18-L1. A statistical analysis was performed according to each transformation step. Results The epithelial layer of papilloma and pre-cancerous papilloma lesions had a similar MMP-2 expression, but that of the malignant lesion had a significantly increased MMP-2 expression. HPV 16 and 18 infection rates were 28.6%, 33.3% and 63.6% in papillomas, pre-cancerous papilloma lesions, and SCC. Conclusions A relatively high MMP-2 expression and HPV 16 or 18 infection of papillomas may be associated with early events in the multistep processes of malignant transformation of papillomas.

Abstract
BACKGROUND Human papillomavirus (HPV) prevalence in oropharyngeal squamous cell cancer (SCC) remains variable and studies have estimated that up to 60% may be positive. METHODS One hundred five treatment-naïve oropharyngeal SCC patients were included. HPV genotyping was done by consensus polymerase chain reaction (PCR) and reverse line-blot hybridization assay. HPV prevalence was co-related with sex, age, tobacco consumption, alcohol use, and high-risk sexual behavior. RESULTS HPV prevalence was 22.8%. No significant associations were seen between tobacco or alcohol consumption with HPV status. The mean number of lifetime sexual partners and indulgence in high-risk sexual behavior was significantly more in patients who are HPV positive. There were no significant associations between the 2 groups with respect to the stage of the tumor. CONCLUSION Results of this study confirms that patients who are HPV positive are younger, and with high-risk sexual behavior. We did not find any impact of smoking and alcohol consumption on HPV status.

Abstract
OBJECTIVES The aim of this study was to verify human papillomavirus (HPV) transmission and genotype concordance among heterosexual couples. MATERIALS AND METHODS Thirty-one married couples were evaluated. All male subjects presented with clinically diagnosed HPV-related malignant or potentially malignant lesions and underwent peniscopy and penile swab. Their female counterparts underwent swabs of the uterine cervix and oral mucosa. HPV-DNA detection was performed by polymerase chain reaction and restriction fragment length polymorphism. RESULTS HPV-DNA was detected in the penis, vagina/cervix, and oral cavity of 16 couples (51.61%). Of these, HPV-DNA concordance was observed in 14 couples (87.5%). HPV-DNA was amplified in penile and oral sites of 14 couples. Of these, 13 couples reported fellatio (92.85%), most of them (10 couples, 76.9%) without condom use. HPV-DNA concordance was observed in 7/10 of these couples (70%). The three couples (100%) who reported use of condom during fellatio were HPV-DNA discordant (p = 0.025). CONCLUSIONS Lifetime number of female sexual partners and detection of HPV-DNA in the penile mucosa are surrogate markers of exposure to HPV during marriage. Consistent use of condoms may reduce the risk of HPV transmission. CLINICAL RELEVANCE Oral acquisition of HPV from oro-genital contact is influenced by lack of condom use and previous sexual behavior of the male partner. In addition, oral transmission of the virus due to fellatio is as common as genital transmission.

Abstract
Medical records of dogs diagnosed with oral papillary squamous cell carcinoma between December 2008 and April 2011 were reviewed. Information abstracted included signalment, tumor location, tumor size, computed tomographic (CT) features, evidence of metastatic disease based on cytologic examination of lymph node aspirates and thoracic radiography, treatment, surgical margins, histologic features, and treatment outcome. Dogs included in the study were all sexually altered, predominantly large breed dogs with a mean age of 3.9-years (range, 0.5 to 9.0-years). The most common location was the rostral maxilla. Invasion of underlying bone and lymphadenopathy were evident on CT imaging in most dogs. No evidence of metastasis was found on mandibular lymph node cytology and thoracic radiography. Histologic analysis revealed similar morphologic findings for all surgically resected tumors. Surgical excision with 1–2 cm margins was complete in all cases, with a mean tumor-free interval of 12.1-months.

Abstract
BACKGROUND Little is known about the rates and determinants of oral human papillomavirus (HPV) infection, an infection that is etiologically linked with oropharyngeal cancers. METHODS A cohort of male university students (18-24 years) was examined every 4 months (212 men, 704 visits). Oral specimens were collected via gargle/rinse and swabbing of the oropharynx. Genotyping for HPV-16 and 36 other α-genus types was performed by polymerase chain reaction-based assay. Data on potential determinants were gathered via clinical examination, in-person questionnaire, and biweekly online diary. Hazards ratios (HR) were used to measure associations with incident infection. RESULTS Prevalence of oral HPV infection at enrollment was 7.5%, and 12-month cumulative incidence was 12.3% (95% confidence interval [CI], 7.0, 21.3). Prevalence of oral HPV-16 was 2.8% and 12-month cumulative incidence was 0.8% (95% CI, 0.1%-5.7%). None of the incident oral HPV infections and 28.6% of the prevalent oral HPV infections were detected more than once. In a multivariate model, incident oral HPV infection was associated with recent frequency of performing oral sex (≥1 per week: HR, 3.7; 95% CI, 1.4-9.8), recent anal sex with men (HR, 42.9; 95% CI, 8.8-205.5), current infection with the same HPV type in the genitals (HR, 6.2; 95% CI, 2.4-16.4), and hyponychium (HR, 11.8, 95% CI, 4.1-34.2). CONCLUSIONS Although nearly 20% of sexually active male university students had evidence of oral HPV infection within 12 months, most infections were transient. Human papillomavirus type 16 was not common. Sexual contact and autoinoculation appeared to play independent roles in the transmission of α-genus HPV to the oral cavity of young men.

Abstract
OBJECTIVE To evaluate reproducibility of oral rinse self-collection for human papillomavirus (HPV) detection and investigate associations between oral HPV, oral lesions, immune and sociodemographic factors, we performed a cross-sectional study of older adults with human immunodeficiency virus (HIV) infection. STUDY DESIGN We collected oral rinse samples from 52 subjects at 2 different times of day, followed by an oral examination and interview. We identified HPV with the use of polymerase chain reaction platforms optimized for detection of mucosal and cutaneous types. RESULTS Eighty-seven percent of individuals had oral HPV, of which 23% had oncogenic alpha, 40% had nononcogenic alpha, and 46% had beta or gamma HPV. Paired oral specimens were concordant in all parameters tested. Significant associations observed for oral HPV with increased HIV viral load, hepatitis C seropositivity, history of sexually transmitted diseases, and lifetime number of sexual partners. CONCLUSIONS Oral cavity may be a reservoir of subclinical HPV in older adults who have HIV infection. Understanding natural history, transmission, and potential implications of oral HPV warrants further investigations.

Abstract
Human papillomavirus (HPV) infections have received considerable attention in recent years. Of the 120 or so known types of the virus, some cause a variety of benign wart-like lesions of the skin and genital and oral mucosae, whilst others are aetiologically associated with cervical and anogenital cancers. Recent epidemiologic evidence suggests that HPV may also be an independent risk factor for oropharyngeal cancer. In this context it has been suggested that HPV virus may modulate the process of carcinogenesis in some tobacco and alcohol induced oropharyngeal cancers and act as the primary oncogenic agent for inducing carcinogenesis among non-smokers. Dental practitioners have a major role in detecting all lesions of the oral mucosa caused, or possibly caused, by HPV. This paper briefly reviews the current state of knowledge of molecular and clinical aspects of HPV infections of the oral mucosa.

Abstract
BACKGROUND There are no previous longitudinal studies on genotype-specific natural history of human papillomavirus (HPV) infections in oral mucosa of women. METHODS In the Finnish Family HPV Study, 329 pregnant women were enrolled and followed up. HPV-genotyping of oral scrapings was performed with nested PCR and Multimetrix® test (Progen, Heidelberg, Germany). Incidence and clearance times and rates for each HPV-genotype identified in oral mucosa were determined. Predictors for incident and cleared HPV infections for species 7/9 genotypes were analyzed using Poisson regression model. RESULTS Altogether, 115 baseline HPV-negative women acquired incident oral HPV infection, and 79 women cleared their infection. HPV16 and multiple HPVs most frequently caused incident infections (65% and 12%) in 13.3 and 17.1 months respectively, followed by HPV58, HPV18 and HPV6 (close to 5% each) in 11-24 months. HPV58, HPV18 and HPV66 were the most common to clear. HPV6 and HPV11 had the shortest clearance times, 4.6 months and 2.5 months, and the highest clearance rates, 225.5/1000 wmr and 400/1000 wmr, respectively. The protective factors for incident oral HPV-species 7/9 infections were 1) new pregnancy during follow-up and 2) having the same sexual partner during FU. Increased clearance was related with older age and a history of atopic reactions, whereas previous sexually transmitted disease and new pregnancy were associated with decreased clearance. CONCLUSIONS HPV16 was the most frequent genotype to cause an incident oral HPV-infection. Low risk HPV genotypes cleared from oral mucosa more quickly than high risk HPV genotypes. Pregnancy affected the outcome of oral HPV infection.

Abstract
PURPOSE A history of allergies is associated with a decreased risk of several types of cancers. Potential mechanisms include enhanced immune surveillance against tumor cells early in disease development and/or carcinogenic infectious agents. We tested whether allergies are inversely associated with oral squamous cell carcinoma (OSCC), accounting for factors that may modify the association, such as tumor site, stage, and HPV infection. METHODS We estimated odds ratios (OR) and 95 % confidence intervals (CI) for the association between allergy history (including different types of allergies) and OSCC, adjusted for potential confounders, among 400 cases and 613 controls. Analyses were also stratified by site, stage, and measures of HPV infection. RESULTS We observed a weak inverse association between history of any allergy and OSCC (OR = 0.81, 95 % CI 0.61-1.08). This association was present only for allergies to airborne allergens (dust/pollen/mold) (OR = 0.67; 95 % CI 0.48-0.93). The inverse associations with airborne allergies were slightly stronger for oropharyngeal SCC (OR = 0.56; 95 % CI 0.35-0.90) than for oral cavity SCC (OR = 0.71; 95 % CI 0.49-1.05) and present only for later-stage cancers (OR = 0.42; 95 % CI 0.26-0.66) as opposed to earlier-stage cancers (OR = 0.98; 95 % CI 0.66-1.46). Inverse associations were not particularly present or stronger among HPV-16-seropositive individuals or for HPV DNA-positive OSCC. CONCLUSION There is an inverse association between history of allergies to dust, pollen, or mold and OSCC. Whether the inverse association involves heightened immune surveillance, increased immune response to HPV or other antigen, or other carcinogenic mechanism remains to be determined in more definitive studies.

Abstract
Background Human papillomavirus (HPV) infections have been linked to a subset of oral and oropharyngeal cancers. However, little is known on the natural history of oral HPV infections. We designed the prospective Finnish HPV Family Study to assess the dynamics of HPV infections in parents and their infants. This study reports HPV genotype distribution and virus persistence in oral mucosa of the mothers. Materials and Methods Totally, 324 pregnant women were enrolled at the 3rd trimester of pregnancy and followed-up for 6 years. Oral scrapings taken with a brush were collected and HPV-genotyping was performed with nested PCR and Multimetrix® test (Progen, Heidelberg, Germany). The predictors of persistent oral HPV species 7/9 infections were analyzed using generalized estimating equation models. Results The point prevalence of oral HPV varied from 15% to 24% during the 6-year follow-up. Altogether, 18 HPV genotypes were identified either as single or multiple-type oral infections. HPV16 was the most prevalent type at 9.7%–18.4%, followed by HPV18, HPV6, and multiple infections. Altogether, 74 women had persistent oral HPV infection determined as at least two consecutive samples positive with the same HPV genotype. HPV16 and HPV6 were the two most frequent types to persist (76% and 9%) for a mean of 18.6 and 20.2 months, respectively, followed by multiple infections (8%) for 18.3 months. An increased risk for persistent oral HPV infection with species 7/9 was associated with being seropositive for low-risk (LR)-HPV-types at baseline, whereas the use of oral contraceptives and a second pregnancy during follow-up were protective. Clinical oral lesions were detected in 17% of these women, one-third of whom had persistent oral HPV-infections. Conclusion HPV16 and HPV6 were the most common genotypes in oral HPV-infections and were also most likely to persist. Use of oral contraceptives and a second pregnancy protected against oral HPV persistence.

Abstract
Oral cancer is one of the most common cancers and it constitutes a major health problem particularly in developing countries. Oral squamous cell carcinoma (OSCC) represents the most frequent of all oral neoplasms. Several risk factors have been well characterized to be associated with OSCC with substantial evidences. While tobacco and alcohol are the primary risk factors for OSCC development, many epidemiological studies report a strong association with human papillomavirus (HPV) in a subset of OSCC. This article presents our current knowledge on the relationship between HPV and development of OSCC. HPVs are DNA viruses that specifically target the basal cells of the epithelial mucosa. Most experimental data are consistent with the hypothesis that HPV plays a causal role in oral carcinogenesis. Genotypes, such as HPV1 infect epidermal cells, whereas HPV6, 11, 16 and 18 infect epithelial cells of the oral cavity and other mucosal surfaces. Several studies have shown that there is an increased risk of head and neck cancer in the two major HPV 16 oncogenes E6 and E7 -positive patients. The presence of antibodies to HPV E6 and E7 proteins was found to be more associated with tumors of the oro-pharynx than of the oral cavity. However, HPV alone appears to be insufficient as the cause of OSCC but requires other co-factors. Although a viral association within a subset of OSCC has been shown, the molecular and histopathological characteristics of these tumors have yet to be clearly defined.

Abstract
BACKGROUND In addition to the anogenital malignancies, human papillomavirus (HPV) has been linked to oropharyngeal cancer as an important risk factor in both men and women. Knowledge of oral HPV infection among males is needed to elucidate the transmission routes and potential for prevention. OBJECTIVE To assess the prevalence, genotype distribution, and incidence of oral HPV infections among healthy Finnish men followed for 7 yr. DESIGN, SETTING, AND PARTICIPANTS Oral scrapings for HPV testing were taken from 131 fathers-to-be (mean age: 28.9 yr) at baseline and at 2-mo, 6-mo, 12-mo, 24-mo, 36-mo, and 7-yr follow-up visits to detect prevalent and incident HPV infections. Purified DNA extracted from scrapings was used for HPV genotyping, with the Multimetrix kit (Progen Biotechnik, Heidelberg, Germany) detecting 24 genotypes. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Point prevalence, genotype distribution, and incident rates of oral HPV infections. Demographic data were collected using structured questionnaires, and covariates of incident oral HPV infections were analysed using uni- and multivariate Poisson regression (for panel data). RESULTS AND LIMITATIONS The point prevalence of oral HPV infection fluctuated from 15.1% to 31.1% during the follow-up period. In total, 17 different HPV genotypes were found. At baseline, the single most frequent genotype among the HPV-positive samples was HPV16 (33.3%; 8 of 24), followed by HPV33 (12.5%) and HPV82 (12.5%). Multiple-type infections comprised 16.7% (4 of 24), HPV16 being involved in all combinations. For baseline-negative men, the mean time to the first incident infection ranged from 3.9 mo (HPV82) to 25.7 mo (HPV56). None of the demographic factors was a significant independent predictor of incident oral HPV infections in multivariate models. CONCLUSIONS Detection of oral HPV DNA carriage in men is common, HPV16 being the most prevalent genotype. Oral mucosa may play a significant role in HPV transmission.
