Abstract
Human papillomaviruses (HPVs) are widespread, sexually transmitted group of viruses that infect most individuals at some stage, causing genital warts and cancers. They are members of the Papillomaviridae family, which contains about 400 HPV types. China is among the high HPV burden countries with reported infections of multiple HPV types, accounting for 17.3% of global deaths and 18.2% of global new cases. Thus, understanding the genetic variation and geographic diversity characteristics of HPVs isolated in China is critical for global HPV prevention strategies. Thus, we analyzed the available HPV genome sequences isolated in China that grouped into two categories (alpha- and gamma-papillomaviruses) based on full-length genomes. The most common were HPV-16, -6, -58, and -52 respectively. In addition, four of the novel strains isolated in China, e.g. TG550, JDFY01, CH2, and L55 clustered with the HPV-mSK 159, 244, 201, and 200 respectively. Our phylogeographic network analysis indicated that the L55, TG550, and CH2 are genetically identical to the mSK 200, 046, and 201 respectively, while JDFY01 appeared separately, connected to the mSK-040 following five mutational steps. Also, we found ten recombination events among HPV-6/11 types within their E1, E2, E7, L1/L2 proteins, and Long Control Region ORFs. We achieved the consensus amino acid sequences of HPV proteins and found a conserved stretch of amino acids within E5A of all HPVs circulating in China. These findings offer valued insights into the genetic relationships, distribution, and evolution of the HPVs in China that may assist in adapting effective HPV preventive measures.

Abstract
BACKGROUND Oral focal epithelial hyperplasia (FEH) is an uncommon infection affecting humans, chimpanzees, bonobos, and howler monkeys. This study describes 10 cases of free-ranging brown howler monkeys (Alouatta guariba clamitans) diagnosed with FEH and Alouatta guariba Papillomavirus 1 (AgPV 1). METHODS We analyzed demographic characteristics, rescue conditions, clinical and pathological findings, and species-specific behavior factors in these cases. The study assessed the frequency of occurrence and potential contributing factors of FEH and AgPV 1 infection. RESULTS The frequency of FEH was 8.13%. Most affected howlers were adult or geriatric males with comorbidities or stressful conditions. Clinical and pathological observations were consistent with AgPV 1 infection. Species-specific behaviors and environmental stressors were identified as contributing factors. CONCLUSIONS FEH associated with AgPV 1 affected mainly adult or geriatric males with ongoing comorbidities or stressful conditions. Further research is needed to understand these factors for effective management.

Abstract
Squamous papilloma is a benign neoplasm that originates from the stratified squamous epithelium of the mucous membrane. Its principal etiological factor is human papillomavirus infection, with a predilection for manifesting within the oral cavity. Squamous papilloma predominantly affects regions on the palate, cheeks, lips and tongue. However, to the best of our knowledge, the occurrence of squamous papilloma within the confines of the mandible remains unreported hitherto. The present report documents a case of squamous papilloma involving the mandible who was managed at the First Affiliated Hospital of Sun Yat-sen University (Guangzhou, China) in January 2023. The patient underwent a series of recurrent jaw inflammations, manifesting with malignant imaging characteristics. Subsequent pathological analysis confirmed a diagnosis of papilloma in the jaw. The present report highlights the pivotal role of prolonged inflammation in the genesis of jaw squamous papilloma, prompting avenues for further investigation, including the potential of inflammation to induce aberrant cell growth, mediate cell interactions, orchestrate cytokine actions and influence stress mediators. In addition, the current study posits a plausible connection between persistent inflammation, compromised epithelial integrity and an increased likelihood of head and neck papilloma, particularly concerning human papillomavirus infection. This article delineates the clinical attributes of the uncommon manifestations of jaw papilloma and delves into the associated mechanisms, thereby contributing to an enhanced comprehension of jaw disorders. This comprehensive insight equips clinicians with a heightened knowledge base for more precise diagnosis and treatment of analogous cases.

Abstract
Oral squamous cell carcinoma (OSCC) is the most common malignancy of the oral cavity and accounts for >90% of all oral cancers. Despite advances in diagnostic procedures and therapeutic interventions, overall survival has not improved significantly in recent decades, primarily due to late diagnosis, locoregional recurrence and treatment resistance. Identifying reliable biomarkers for early detection, prognosis evaluation and treatment response prediction is critical for improving clinical outcomes in patients with OSCC. In the present review, the prognostic and predictive utility of circulating biomarkers, such as circulating tumour cells, serological biomarkers and histological and genetic biomarkers, were explored in the context of OSCC. In addition, the potential role of immune checkpoints in the treatment of OSCC was highlighted and the rapidly evolving field of liquid biopsy and its potential to revolutionize diagnosis, prognosis evaluation and treatment were examined. The existing evidence for the clinical utility of these biomarkers was critically evaluated and the challenges and limitations associated with their introduction into routine clinical practice were addressed. In conclusion, the present review highlights the promising role of biomarkers in improving the current understanding of the pathogenesis of OSCC and offers potential avenues for improving patient care through personalized medicine approaches.

HPV-Related Oral Lesions: YouTube Videos Suitability for Preventive Interventions including Mass-Reach Health Communication and Promotion of HPV Vaccination. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:5972.

Abstract
Given the need to improve patient knowledge about HPV-related oral lesions, awareness of HPV infection prevention measures, and compliance with vaccination, as well as patient demand for free and easy access to well-tailored and time-saving health information, the present cross-sectional study examined the accuracy of relevant YouTube videos and their suitability for mass-reach health communication and HPV vaccination promotion. A video search was performed, using keywords obtained from the Google Trends website, until 9 January 2023. Video selection and data collection were performed by independent, pre-calibrated examiners. Descriptive statistics were performed on videos' general characteristics, source reliability, popularity, information and quality, content topics, vaccination-encouraging/discouraging messages, and educational value. Pearson's correlation was calculated between educational value and all parameters. Mann-Whitney U test compared very low/low vs. medium/good/excellent educational value and HPV vaccination-encouraging vs. -discouraging videos. Most of the 97 YouTube videos analyzed were moderately accurate and reliable, 53% had moderate/good/excellent educational value, and 80% encouraged HPV vaccination, making them suitable for mass-reach communication. The limited role of oral healthcare providers in uploading relevant content, with the poor dissemination of information about HPV-related benign and malignant oral lesions, may be expanded by purposefully using YouTube and other mass media to improve patient knowledge of HPV-related oral lesions and promote HPV vaccination, which also underscores its potential beneficial oral effects.

Abstract
Human papilloma virus (HPV) causes cervical and many other cancers. Recent trend in vaccine design is shifted toward epitope-based developments that are more specific, safe, and easy to produce. In this study, we predicted eight immunogenic peptides of CD4+ and CD8+ T-lymphocytes (MHC class I and II as M1 and M2) including early proteins (E2 and E6), major (L1) and minor capsid protein (L2). Male and female Sprague Dawly rats in groups were immunized with each synthetic peptide. L1M1, L1M2, L2M1, and L2M2 induced significant immunogenic response compared to E2M1, E2M2, E6M1 and E6M2. We observed optimal titer of IgG antibodies (>1.25 g/L), interferon-γ (>64 ng/L), and granzyme-B (>40 pg/mL) compared to control at second booster dose (240 µg/500 µL). The induction of peptide-specific IgG antibodies in immunized rats indicates the T-cell dependent B-lymphocyte activation. A substantial CD4+ and CD8+ cell count was observed at 240 µg/500 µL. In male and female rats, CD8+ cell count for L1 and L2 peptide is 3000 and 3118, and CD4+ is 3369 and 3484 respectively compared to control. In conclusion, we demonstrated that L1M1, L1M2, L2M1, L2M2 are likely to contain potential epitopes for induction of immune responses supporting the feasibility of peptide-based vaccine development for HPV.

Abstract
The present systematic review aimed to assess the prevalence of oral HPV-related lesions, categorized as benign (verruca vulgaris "VV", squamous cell papilloma "SP", condyloma acuminata "CA", and focal epithelial hyperplasia "FEH") and malignant (oral squamous cell carcinoma "OSCC"), in descending order of occurrence in pediatric subjects (≤18 years of age). The secondary objectives were to evaluate the frequency and types of oral lesions described in relation to HPV genotypes and the HPV vaccine type (if any). The study protocol, compliant with the PRISMA statement, was registered at PROSPERO (CRD42022352268). Data from 60 studies, of which quality was assessed using the ROBINS-I tool, were independently extracted and synthesized. Along with seven poorly described benign HPV-related oral lesions that could not be categorized, a total of 146 HPV-related oral lesions, namely 47.26% (n = 69) VV, SP, and CA, 51.37% (n = 75) FEH, and 1.37% (n = 2) OSSC, were diagnosed in 153 pediatric subjects (M:F ratio = 1:1.4) with a mean age of lesion onset of 8.46 years. The viral genotypes detected were HPV-13 (30.61%), -6 (20.41%), -11 (16.33%), HPV-2 (12.24%), -32 (10.20%), -57 (6.12%), and -16 (4.08%). No HPV vaccination was reported in any case. Further studies should be conducted to evaluate the prevalence of HPV-related benign and malignant lesions and the potential role of HPV and associated vaccination in oral carcinogenesis in pediatric subjects.

Abstract
This report presents the case of a 36-year-old male who was diagnosed with oral squamous papilloma in the palatal region. Excision was planned. The patient in the meantime chewed upon custard apple leaves and reported that the lesion prolapsed over the next few days. On examination, the site showed no signs of scarring or contracture and presented with healthy palatal tissue. The patient was prevented from requiring surgery, which would have shown a longer healing period with heavy reliance on an expensive resource base. This novel observation highlights the benefits of custard apple (Annona squamosa) leaves and warrants that its hepatoprotective, anticancer, antidiabetic, antioxidant, antibacterial, anti-obesity, and lipid-lowering properties are studied in an astute scientific setup with a well-drawn-out research plan.

Abstract
Objective Human papillomavirus (HPV) comprises around 120 genotypically related viruses, classified into low- and high-risk HPVs, which are capable of replicating inside the keratinocytes of skin or mucous membranes. Studies suggest that infections with HPV-16 or HPV-18 have a higher rate of developing cancer. The aim of our study was to detect HPV early, and to estimate the genotype-specific prevalence of HPV in apparently healthy and asymptomatic females in Bangladesh. Method After cervical swab specimen collection, a VIA test was performed to identify any type of abnormality in the cervix. A multiplex PCR amplification of HPV DNA, using L1 consensus primer systems, was performed with type-specific primers, followed by sequencing to detect HPV genotypes. Result Of the 417 females, 121 were found to be HPV positive. The most prevalent high-risk HPV genotypes were found to be HPV-16 and HPV-18. Different patient demographic parameters, such as age, socioeconomic status, education, and history of first intercourse, were also studied to establish correlations with HPV infection. Conclusion Our results might provide some insights into factors that influence the development of cervical cancer. They might also help in guiding better patient management, increased public health awareness, further testing, and the implementation of existing vaccines.

Abstract
Human papillomavirus (HPV) is a virus with the potential to infect human epithelial cells and an etiological agent of many types of cancer, including head and neck cancer. The aim of the study was to determine the prevalence of HPV infection in patients with head and neck squamous cell carcinoma (HNSCC), patients with chronic tonsillitis, and healthy individuals, and to establish high- and low-risk HPV genotypes in these groups. The objectives also comprised the delineation of the relationship between the infection with high- or low-risk HPV subtypes and clinicopathological and demographic characteristics of the study groups. This study was composed of 76 patients diagnosed with HNSCC, 71 patients with chronic tonsillitis, and 168 cases without either of these conditions (the control group). HPV detection and identification of subtypes were performed on isolated DNA using a test which allowed detection of 33 common high-risk and low-risk HPV subtypes. The prevalence of HPV infection was 42.1%, 25.4%, and 37.5% in HNSCC, chronic tonsillitis, and control groups, respectively. HPV 16 was the most prevalent genotype in all groups and the non-oncogenic HPV 43/44 was frequent in HNSCC patients. This analysis provides insight into the prevalence of oral oncogenic and non-oncogenic HPVs in patients with head and neck cancer, patients with chronic tonsillitis and healthy individuals, and leads to the conclusion that further investigations are warranted to examine a larger cohort of patients focusing on high- and low-risk HPV genotypes. Efforts should be focused on screening and prevention strategies, and therefore, it is important to introduce tools for effective detection of HPV genotypes. Furthermore, given the role of vaccines against oral HPV infection, our observations lead to the suggestion that HPV vaccination should be of considerable importance in public health strategies.

Abstract
Papillomaviruses are one of the oldest viruses known, dating back 330 million years. During this long evolution, human papillomaviruses (HPV) have developed into hijackers of human cellular and immune systems in which they replicate and remain silent. Systematic studies on oral HPV infections and their outcomes are still scarce. Oral HPV infections have been linked to sexual behaviour, but recent evidence supports their horizontal, mouth‐to‐mouth, transmission. Most HPV infections in infants are acquired vertically from the mother during the intrauterine period, during delivery, or later via saliva. The best‐known benign clinical manifestations of HPV infection are oral papilloma/condyloma and focal epithelial hyperplasia. Evidence is emerging which suggests that some oral HPV infections might persist. Persistent HPV infection is mandatory for HPV‐associated malignant transformation. However, progression of HPV‐induced lesions to malignancy requires additional cofactors. In the early 1980s, we provided the first evidence that a subset of oral cancers and other head and neck cancers might be causally linked to HPV infection. This review summarizes current knowledge on the virus itself, its transmission modes, as well as the full spectrum of oral HPV infections – from asymptomatic infections to benign, potentially malignant oral lesions, and squamous cell carcinoma.

Abstract
PURPOSE Human papillomavirus (HPV) infection represents the primary cause of anogenital premalignant and malignant disease. Regarding the high prevalence of cervical HPV infection and the increasing incidence of HPV associated oropharyngeal cancer in recent years, a significant viral transmission from the cervical to the oral site, possibly depending on the sexual behavior must be considered. The present study aims to determine the prevalence of oral HPV infection in cervical HPV positive and negative women and their sexual partners. METHODS Cervical HPV positive and negative women and their sexual partners took part in the study. Cervical smears, oral smears and mouthwashes were taken from women attending gynecological outpatient clinics in two different institutions. Further, oral smears as well as mouthwashes of their sexual partners were obtained whenever possible. HPV genotyping was performed using the Cobas® polymerase chain reaction and nucleic acid hybridization assay for the detection of 14 high-risk HPV types. In addition, all participants were invited to complete a personal questionnaire. RESULTS 144 HPV positive and 77 HPV negative women and altogether 157 sexual partners took part in the study. Age, sexual behaviour, medication, smoking and alcohol consumption were distributed equally in both groups. Cervical HPV positive women had a significantly higher number of sexual partners. One woman with a HPV positive cervical smear and one partner of a woman with a HPV positive cervical smear showed an oral HPV infection. No oral HPV infections were detected in the HPV negative control group. The overall incidence of oral HPV infection was 0.5%, the incidence of oral HPV infection in women with a positive cervical smear was 0.7%. CONCLUSION The data demonstrate that the overall risk of an oral HPV infection is low. HPV transmission to the oropharynx by autoinoculation or oral-genital contact constitute a rare and unlikely event.

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.

Abstract
This study aimed to examine the possible association of human papillomavirus (HPV) with oral cavity squamous cell carcinomas (OCSCCs) in Saudi Arabia. Forty-five paraffin-embedded tumor blocks that represent different subsets of OCSCCs between 2010 and 2014 were retrieved and histologically evaluated. The presence of high-risk HPV (16, 18, 31, and 33) was assessed by p16-immunohistochemistry followed by DNA detection using in situ hybridization technique. Twenty-four patients were male with the mean age of 59.3 years, and 21 patients were female with the mean age of 61.2 years. Forty-one cases were positive for p16 immunostaining, and the remaining four cases were negative. However, none of the 45 cases showed DNA-expression for any HPV subtypes (16, 18, 31, and 33). High-risk HPV appears not to be involved in the etiology of OCSCCs in older Saudi patients, but further studies with cross section of a younger age group are still required.

Abstract
BACKGROUND This study presents a prediction of putative miRNA within several Human Papillomavirus (HPV) types by using bioinformatics tools and a strategy based on sequence and structure alignment. Currently, little is known about HPV miRNAs. METHODS Computational methods have been widely applied in the identification of novel miRNAs when analyzing genome sequences. Here, ten whole-genome sequences from HPV-6, -11, -16, -18, -31, -33, -35, -45, -52, and -58 were analyzed. Software based on local contiguous structure-sequence features and support vector machine (SVM), as well as additional bioinformatics tools, were utilized for identification and classification of real and pseudo microRNA precursors. RESULTS An initial analysis predicted 200 putative pre-miRNAs for all the ten HPV genome variants. To derive a smaller set of pre-miRNAs candidates, stringent validation criteria was conducted by applying <‒10 ΔG value (Gibbs Free Energy). Thus, only pre-miRNAs with total scores above the cut-off points of 90% were considered as putative pre-miRNAs. As a result of this strategy, 19 pre-miRNAs were selected (hpv-pre-miRNAs). These novel pre-miRNAs were located in different clusters within HPV genomes and some of them were positioned at splice regions. Additionally, the 19 identified pre-miRNAs sequences varied between HPV genotypes. Interestingly, the newly identified miRNAs, 297, 27b, 500, 501-5, and 509-3-5p, were closely implicated in carcinogenesis participating in cellular longevity, cell cycle, metastasis, apoptosis evasion, tissue invasion and cellular growth pathways. CONCLUSIONS The novel putative miRNAs candidates could be promising biomarkers of HPV infection and furthermore, could be targeted for potential therapeutic interventions in HPV-induced malignancies.

Abstract
OBJECTIVE This study was designed to investigate the co-prevalence of cervical and oropharyngeal human papillomavirus (HPV) infection in patients with HPV-related high-grade disease of the uterine cervix (high-grade squamous intraepithelial lesion [HSIL]). MATERIALS AND METHODS In a prospective cohort study, women with abnormal cervical cytology admitted to our colposcopy units received HPV testing of the uterine cervix and the oropharynx via smear. From a subset of patients, oral lavage was collected to compare detection rates of HPV DNA between lavage and swab. Patients with confirmed high-risk HPV (HR-HPV)-positive HSIL of the cervix were further investigated. Sexual behavior and lifestyle factors were documented with a standardized questionnaire. RESULTS Two hundred thirty-five women were included in the study. Of the 235 women, 135 (57.5%) were cervically HR-HPV positive with histologically confirmed high-grade cervical intraepithelial lesion (median [range] age = 30 [21-45] years). Of these, only 6 (4.4%) also had a positive oral specimen. In 3 (50%) of the 6 cases, the same HPV type was detected in oral and cervical samples (HPV 16, 35, and 45). Oral HPV detection was not higher when combining swab and lavage compared with swab alone. A relation between sexual behavior and oral HPV detection could not be demonstrated. CONCLUSIONS Oral HPV prevalence in women with cervical HPV infection and HSIL is low. Simultaneous testing of oropharyngeal and cervical HPV infection does not seem promising as future screening strategy.

SAGE Open Med 2018; 6:2050312118765604. [PMID: 29623202 PMCID: PMC5881963 DOI: 10.1177/2050312118765604] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2017] [Accepted: 02/26/2018] [Indexed: 12/19/2022] Open
Abstract
Background: Among developing countries, Thailand shows no increase in the incidence of human papillomavirus–driven oropharyngeal cancer. The causal role of human papillomavirus infection in this pathology has not been researched thoroughly. Methods: A hospital-based, case–control study was performed which included 104 patients with newly diagnosed oral and oropharyngeal squamous cell carcinomas and 104 individuals without cancer. The Cervista high-risk human papillomavirus and 16/18 assays were used to detect human papillomavirus. Odds ratios were used to assess the association between high-risk genotypes of human papillomavirus and the cancers. Results: High-risk human papillomavirus was detected in 4 of 52 (7.7%) oral cancer cases, 6 of 52 (11.5%) oropharyngeal cancer cases, and 1 of 104 (0.96%) control subjects. Of 104 cancer patients in the study, 83 were smokers. High-risk human papillomavirus was significantly associated with oropharyngeal cancer (odds ratio = 13.44, 95% confidence interval = 1.6–114.8) but was nonsignificantly associated with oral cancer (odds ratio = 8.58, 95% confidence interval = 0.9–78.9). However, after adjustment for smoking, high-risk human papillomavirus was determined to be nonsignificantly associated with oropharyngeal cancer (adjusted odds ratio = 5.83, 95% confidence interval = 0.8–43.5). Conclusion: Although low human papillomavirus prevalence was observed, the rate of high-risk human papillomavirus infection in the cancer group was still higher than that in the control group. Smoking may have an influence on the etiology of human papillomavirus–related cancers. However, the study is underpowered to clarify the role of human papillomavirus as the independent risk factor for oral and oropharyngeal cancers in the Thai population.

Abstract
Tanshinone IIA (TAN) is one of the major functional compounds of Salvia miltiorrhiza Bunge and possesses the ability to suppress the growth of multiple cancer cell types via its apoptosis‐ and autophagy‐inducing functions. In this study, the effect of TAN therapy on the survival of oral squamous cell carcinoma (OSCC) was evaluated, and the underlying mechanism involved in the treatment was investigated. Human oral squamous cell carcinoma cell SCC‐9 was used for in vitro assays and induction in an OSCC xenograft mouse model. The tumor cells were subjected to TAN administration at different concentrations. Then the apoptosis and autophagy processes in SCC‐9 cells were evaluated and the activities of Beclin‐1/Atg7/Atg12‐Atg5 and PI3K/Akt/mTOR pathways were determined. In addition, by knocking down the expression of Beclin‐1 in SCC‐9 cells, the study also assessed the role of the indicator in the anti‐OSCC effect of TAN. Results of in vitro assays were further validated with an OSCC xenograft mouse model. Administration of TAN‐induced cell apoptosis and upregulated the expression of cleaved‐caspase‐3. Simultaneously, the autophagy process in SCC‐9 cells was initiated by TAN, which was signaled by the formation of autophagosomes and increase in the ratio of LC3 II/LC3I. The above processes were associated with the activation of Beclin‐1/Atg7/Atg12‐Atg5 signaling and inhibition of PI3K/Akt/mTOR signaling. Our results also inferred a partially Beclin‐1‐dependent mechanism of action of TAN in OSCC cells: knockdown of the Beclin‐1 blocked the effect of TAN on SCC‐9 cells both in vivo and in vitro. Our study provided a preliminary explanation of the mechanism involved in TAN effect: the agent exerted its autophagy‐inducing effect against OSCC in a multipronged manner, by both inducing the Beclin‐1/Atg7/Atg12‐Atg5 pathway and suppressing the PI3K/Akt/mTOR pathway.

Abstract
BACKGROUND The aim of this study was to identify the presence and frequency of human papillomavirus (HPV) nucleic acid in p16-positive oral squamous cell carcinomas (OSCCs), to assess whether the virus was transcriptionally active and to assess the utility of p16 overexpression as a surrogate marker for HPV in OSCC. METHODS Forty-six OSCC patients treated between 2007 and 2011 with available formalin-fixed paraffin-embedded (FFPE) specimens were included. Twenty-three patients were positive for p16 by immunohistochemistry (IHC) and these were matched with 23 patients with p16-negative tumours. Laser capture microdissection of the FFPE OSCC tissues was undertaken to isolate invasive tumour tissue. DNA was extracted and tested for high-risk HPV types using a PCR-ELISA method based on the L1 SPF10 consensus primers, and a real-time PCR method targeting HPV-16 and HPV-18 E6 region. Genotyping of HPV-positive cases was performed using a reverse line blot hybridization assay (Inno-LiPA). RNAScope® (a chromogenic RNA in situ hybridization assay) was utilized to detect E6/E7 mRNA of known high-risk HPV types for detection of transcriptionally active virus. RESULTS HPV DNA was found in 3 OSCC cases, all of which were p16 IHC-positive. Two cases were genotyped as HPV-16 and one as HPV-33. Only one of the HPV-16 cases was confirmed to harbour transcriptionally active virus via HPV RNA ISH. CONCLUSION We have shown that the presence of transcriptionally active HPV rarely occurs in OSCC and that p16 is not an appropriate surrogate marker for HPV in OSCC cases. We propose that non-viral mechanisms are responsible for the majority of IHC p16 overexpression in OSCC.

[PMID: 28923272 DOI: 10.1016/j.joms.2017.08.030] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2017] [Revised: 08/10/2017] [Accepted: 08/10/2017] [Indexed: 10/19/2022]
Abstract
PURPOSE We sought to study the spectrum of oral pathologies presenting clinically with papillary-verrucous features. MATERIALS AND METHODS A 10-year (2007 to 2016) retrospective study of oral papillary lesions was undertaken. All biopsy reports that included a clinical description of papillary or verrucous architecture were retrieved. The data collected included clinical features, size, color, location, histopathologic diagnosis, age, and gender. RESULTS The study included 137 patients, with a total of 150 lesions. The ages ranged from 10 weeks to 84 years (mean, 49 years). Histopathologically, 60% of cases were human papillomavirus (HPV) related, 19% showed hyperplasia, 11% had hyperplastic candidiasis, 7% were dysplastic or malignant, and 3% were benign of unknown etiology. Among the 7% of lesions diagnosed with dysplasia or malignancy, only 60% were suspected to have malignancy at the time of biopsy. HPV-related lesions and hyperplasia were most frequently found on the tongue (38% and 41%, respectively) and soft palate (21% and 14%, respectively). Hyperplastic candidiasis was most frequently found on the buccal mucosa and tongue (35% and 24%, respectively). Squamous cell carcinoma was found in 1.3% of total lesions and verrucous carcinoma in 1.3%. Of the verrucous or papillary malignant lesions, 50% were found on the gingiva. Most malignant lesions occurred in the 40- to 60-year age group. CONCLUSIONS The results of this study suggest that, because of the wide spectrum of entities presenting clinically with a papillary-verrucous architecture, biopsy is necessary for diagnosis. The clinical presentation allowed for overall accurate diagnosis in only 47% of cases and 60% accuracy in dysplastic or malignant cases. It is of considerable importance to correctly identify those lesions that are HPV related but at the same time to rule out those lesions that are unrelated to HPV to help alleviate a patient's anxiety. Most important, biopsy is mandatory for the recognition of malignant lesions with a papillary-verrucous architecture, which may mimic other benign entities in the group of papillary-verrucous lesions.

Abstract
OBJECTIVE The level of awareness of patients receiving supportive periodontal therapy (SPT) concerning the role of smoking as a risk factor for oral health was investigated. MATERIALS AND METHODS A questionnaire was administered to 158 patients previously treated for periodontitis in four periodontally oriented private dental offices in Rome. The generalized linear model was used to test the simultaneous effect of questions posed to all patients. Fisher's exact test was used to verify significant associations among qualitative variables. RESULTS Only 53.79% of the total sample referred having been informed by the dentist/hygienist about smoking as an oral health risk factor. About 40% of patients did not know that oral cancer exists and only 36.08% of them reported being informed about it by their own dentist/hygienist. Females are significantly less frequent among ex-smokers than among smokers. Nonsmokers were on periodontal supportive therapy for a longer period than smokers. Patients who started smoking later found harder to quit smoking than those who started earlier. CONCLUSION Awareness of patients in SPT about health risks related to smoking does not assume a change in their harmful behavior. Among oral health professionals, there is not yet a widespread awareness of the importance of their role in increasing patient's motivation to quit.

Abstract
Tetrandrine, a bisbenzylisoquinoline alkaloid, is extracted from the root of the Chinese herb Radix Stephania tetrandra S Moore. This compound has antitumor activity in different cancer cell types. In this study, the effects of tetrandrine on human oral cancer CAL 27 cells were examined. Results indicated that tetrandrine induced cytotoxic activity in CAL 27 cells. Effects were due to cell death by the induction of apoptosis and accompany with autophagy and these effects were concentration- and time-dependent manners. Tetrandrine induced apoptosis was accompanied by alterations in cell morphology, chromatin fragmentation, and caspase activation in CAL 27 cells. Tetrandrine treatment also induced intracellular accumulation of reactive oxygen species (ROS). The generation of ROS may play an important role in tetrandrine-induced apoptosis. Tetrandrine triggered LC3B expression and induced autophagy in CAL 27 cells. Tetrandrine induced apoptosis and autophagy were significantly attenuated by N-acetylcysteine pretreatment that supports the involvement of ROS production. Tetrandrine induced cell death may act through caspase-dependent apoptosis with Beclin-1-induced autophagy in human oral cancer cells. © 2016 Wiley Periodicals, Inc.

Abstract
BACKGROUND Squamous cell carcinoma (SCC) is the most common malignancy of the oral cavity. A relationship between the human papilloma virus (HPV) infection and the prognosis of oral cavity SCC (OCSCC) has been discussed before. OBJECTIVES We investigated the prevalence rate of HPV status in patients with OCSCC, and its effects on clinicopathological characteristics of tumors and patients' prognosis. PATIENTS AND METHODS Sections of formalin-fixed, paraffin-embedded tissue blocks from 114 histopathologically confirmed OCSCC cases were investigated in this study. Polymerase chain reaction (PCR) was applied to evaluate the HPV status in the samples. RESULTS Fifteen (13.16%) cases were identified as HPV positive. The detected viral subtypes in this study were the subtypes 6 and 11. The stage and especially lymph node stage was significantly higher in the HPV positive group compared to the HPV negative group (P = 0.04). Disease free survival (DFS) was remarkably lower in the HPV positive group compared to the HPV negative group (13.9 vs. 49.9 months, P = 0.02). Overall survival (OS) was also significantly inferior in the HPV positive group (15.7 vs. 49.6 months, P = 0.01). In the current study, no significant differences were observed between two groups in relation to the variables of age, gender, tumors site, tumor size, tumor grading and also the recurrence rate. CONCLUSIONS The observed higher mortality rate among the HPV positive group indicates the poorer prognosis of this group in comparison with the HPV negative patients. The incidence rate of HPV infection was low in the studied samples; however, interaction of subtypes 6 and 11 of HPV in poorer prognosis of the patients and a carcinogenic role of HPV in OCSCC cannot be ruled out.

Abstract
Tetrandrine is a bisbenzylisoquinoline alkaloid that was found in the Radix Stephania tetrandra S Moore. It had been reported to induce cytotoxic effects on many human cancer cells. In this study, we investigated the cytotoxic effects of tetrandrine on human oral cancer HSC-3 cells in vitro. Treatments of HSC-3 cells with tetrandrine significantly decreased the percentage of viable cells through the induction of autophagy and apoptosis and these effects are in concentration-dependent manner. To define the mechanism underlying the cytotoxic effects of tetrandrine, we investigated the critical molecular events known to regulate the apoptotic and autophagic machinery. Tetrandrine induced chromatin condensation, internucleosomal DNA fragmentation, activation of caspases-3, -8, and -9, and cleavage of poly (ADP ribose) polymerase (PARP) that were associated with apoptosis, and it also enhanced the expression of LC3-I and -II that were associated with the induction of autophagy in human squamous carcinoma cell line (HSC-3) cells. Tetrandrine induced autophagy in HSC-3 cells was significantly attenuated by bafilomycin A1 (inhibitor of autophagy) pre-treatment that confirmed tetrandrine induced cell death may be associated with the autophagy. In conclusion, we suggest that tetrandrine induced cell death may be through the induction of apoptosis as well as autophagy in human oral cancer HSC-3 cells via PARP, caspases/Becline I/LC3-I/II signaling pathways.

Relationship between CK19 expression, deregulation of normal keratinocyte differentiation pattern and high risk-human papilloma virus infection in oral and oropharyngeal squamous cell carcinoma. Infect Agent Cancer 2015; 10:46.

Abstract
BACKGROUND Simple epithelial keratins appear early during embryonic development and are expressed in non-stratified, ductal and pseudo-stratified epithelial tissues. CK19, the lowest molecular weight keratin, is also expressed in basal layer of squamous epithelia of mucosal surfaces. Previous studies have shown that High Risk-Human Papilloma Virus (HR-HPV) epithelial infection induces cell immortalization via E6 and E7 viral proteins and this, in turn, impairs cytokeratin expression in cancerous cells lines derived from uterine cervix. Here, we demonstrate the possible relationship between HR-HPV(+) oral/oropharyngeal cancer and the high levels of CK19 expression. METHODS We analyzed 38 cases of Oral Squamous Cell Carcinomas/ Oro-Pharyngeal Squamous Cell Carcinomas (OSCCs/OPSCCs) by Immunohistochemistry (IHC) using specific antibody (Ab) detecting CK19, by In Situ Hybridization (ISH) and Polymerase Chain Reaction (PCR) based methods in order to define the HPV infectious status. We also evaluated the variation of CK19 expression in UPCI-SCC-131 (HPV(-)) and UPCI-SCC-154 (HPV(+)) cell lines by immunocytochemistry (ICC) and flow cytometry. RESULTS CK19 OSCC/OPSCC score has been identified multiplying percentage of cancer expressing cells to staining intensity. CK19 expression score in OSCCs/OPSCCs was very different between HPV(+) (mean: 288.0 ± 24.3) and HPV(-) cancers (mean: 66.2 ± 96.9). This difference was statistically significant (p < 0.001) with a strong evidence of correlation (p < 0.001; Spearman's R: +0.72). ROC curve analysis was performed on CK19 expression index related to HPV positivity. Heterogeneous areas of immunoreactivity varying in percentage value, intensity and/or localization were observed in normal epithelium, both perilesional and distant from the tumor with important differences between HR-HPV(+) and HR-HPV(-) carcinomas. By ICC and flow cytometry, the two analyzed cell lines were both CK19 positive but showed a different level of expression, in particular it should be noted that the UPCI-SCC-154 (HPV(+)) cell line had a higher expression than UPCI-SCC-131 (HPV(-)). CONCLUSIONS In this study we demonstrated, for the first time, strong association between CK19 up-regulation and HR-HPV(+) OSCCs/OPSCCs. This test has a good accuracy. We identified ROC curve with a cut-off > 195 for HR-HPV positive results (Sensitivity: 92.3 %; Specificity: 89.3 %). Furthermore, in OSCC/OPSCC, the CK19 test may be useful in identifying HR-HPV infection, the latter being related to HPV E7 potential to disrupt normal cytokeratin expression pattern.

Abstract
OBJECTIVE This study aimed to evaluate the association between human papillomavirus infection and salivary gland tumours in a Scottish cohort. METHODS Specimens from a range of salivary gland tumours operated on between 1997 and 2012 were studied. A tissue microarray constructed from tissue blocks was subjected to p16INK4 (cyclin-dependent kinase inhibitor 2A) immunohistochemistry and in situ hybridisation using probes specific for human papillomavirus, including types 16 and 18. RESULTS A total of 61 tumours (benign and malignant) were deemed suitable for the study. p16INK4 staining yielded three (4.9 per cent) positive samples: one small cell carcinoma, one squamous cell carcinoma and one poorly differentiated carcinoma. Human papillomavirus in situ hybridisation demonstrated a positive signal in the latter sample only (1.6 per cent). CONCLUSION This study demonstrated a very low human papillomavirus detection rate in salivary gland tumours. It can therefore be concluded that human papillomavirus infection is unlikely to play a role in salivary gland neoplasia. Rare human papillomavirus positive cases should be carefully evaluated to exclude the possibility of a metastatic lesion.

Abstract
AbstractObjectives:To evaluate the histopathological findings from post-treatment neck dissection of p16 positive and negative oropharyngeal carcinoma cases, after completion of chemoradiotherapy, and to question the role of neck dissection after a ‘clinically complete response’ to chemoradiotherapy.Methods:Data were collected retrospectively from a cohort of patients treated with curative intent using chemoradiotherapy and post-treatment neck dissection. Primary tumours underwent p16 immunohistochemistry. Neck dissection specimens were examined for viable cancer cells.Results:A total of 76 cases were assessed. Viable cancer cells were detected from neck dissection in 29 per cent of p16 negative cases. Locoregional recurrence occurred in 12.9 per cent of p16 negative cases. The association between p16 positivity in the primary tumour and histopathologically negative neck dissection was significant (p < 0.05).Conclusion:p16 status appeared to be an independent marker of disease control for the cohort in this study. The data raise questions about the role of post-treatment neck dissection in p16 positive cases with a ‘clinically complete response’ to chemoradiotherapy.

Abstract
Head and Neck Squamous Cell Carcinoma accounts for the sixth most common malignancy occurring worldwide with tobacco and alcohol being the two well established risk factors. In the recent years, substantial evidence has been obtained that Human Papilloma Virus (HPV) associated head and neck cancers are on the rise. This article provides an insight into the structure of HPV genome, molecular pathogenesis, detection methods and clinical implications of HPV positive Head and Neck Squamous Cell Carcinoma.

Abstract
High-risk human papillomaviruses (HR-HPV) are considered necessary for the development of cervical cancer. Furthermore, there is no doubt that some types of oral squamous cell carcinoma are associated with HR-HPV. The epidemiology of oral HPV infections in healthy subjects remains unclear due to a lack of knowledge. The objective of this study was to investigate the epidemiology of human papillomavirus infections of the oral mucosa without pathology. A cross-sectional study was performed; samples from 390 women seeking prenatal care, Pap smears, family planning or gynecological diseases were studied. Oral cells were collected by direct swab sampling. Information regarding sociodemographic status, sexual behavior, infectious diseases, contraceptive history and tobacco and alcohol consumption were obtained through direct interviews. HPV and genotypes were detected by type-specific polymerase chain reaction. Our results revealed that 14% of the women studied had an oral HPV infection. Women ≤ 20 years of age had the highest HPV prevalence (24.5%). In total, seven genotypes were identified, including the high-risk genotypes 16, 18, 58 and 59 and the low-risk genotypes 6, 81 and 13, the latter of which is a type exclusive to oral mucosa. Sexual behavior was not associated with the presence of genital HPV types in the oral mucosa. Genital HPV types were present in the oral mucosa of women without associated clinical manifestations; however, sexual behavior was not associated with infection, and therefore others routes of transmission should be explored.

Abstract
OBJECTIVE The aim of this study was to analyze the clinicopathological and immunohistochemical features of oral papillomas. MATERIALS AND METHODS Biopsies of oral papillomas analyzed in the laboratory between 1996-2012 were extracted from the database and used to conduct this retrospective review. The following clinical data were extracted: sex, age, location, clinical appearance, time of evolution, recurrence and first clinical diagnosis. Immunohistochemical analysis for Human Papillomavirus (HPV)and histological evaluation of the lesions were performed. RESULTS A total of 205 papillomas were identified in 197 patients (♂=110, ♀ = 87; mean age = 48.4 ± 17.9 years).The majority of the lesions (n = 47) occurred on the soft palate (23%). The border of the tongue was the second most common site (n = 20, 9.8%). Lesions were more common in males than in females (ratio = 1.26:1). Statistical analysis did not show any correlation between the assessed variables. Clinically, papillomas were predominantly described by the practitioners as small nodules, with a papillary surface (98.1%) and pedunculated attachment(83.1%). Data supported a low recurrence (2.0%) and multiplicity (2.0%). Evolution time varied from a few weeks to several years. Most frequent misdiagnosis was condyloma. Immunohistochemistry rarely showed HPV presence (9.3%). Microscopically, lesions were very often keratinized (93.2%) and showed chronic inflammatory cells (68.8%). CONCLUSIONS In this series papillomas showed a slight male predilection and occurred mostly in the sixth decade of life. Histologically, they were usually keratotic and exhibited variable inflammation. HPV virus was rarely detected by immunohistochemistry. No statistical correlation could be established between clinicopathological features.

Abstract
UNLABELLED Verruca vulgaris (common warts) is a benign lesion of skin and mucous membranes caused by human papillomavirus (HPV). The lesions are typically self-limited but may vary in size and number. The occurrence on the tongue is extremely rare. To the best of our knowledge, only one verruca vulgaris existing in the tongue had been reported in the literature. CASE PRESENTATION A rare case of verruca vulgaris of the tongue occurring in a 36-year-old Caucasian male is presented with a discussion on ethiopathogenesis and the treatment methods. Verruca vulgaris must be remembered in the differential diagnosis of tongue lesions and surgical treatment may provide satisfactory outcomes.

Abstract
Human papillomavirus (HPV) constitutes the majority of newly acquired sexually transmitted infections (STIs) in United States as per the centers for disease control factsheet 2013. Genital HPV is the most common STI with incidence of about 5.5 million world-wide, nearly 75% of sexually active men and women have been exposed to HPV at some point in their lives. Oral Sexual behavior is an important contributor to infection of HPV in the oral mucosa especially in cases known to practice high risk behavior and initiating the same at an early age. HPV infection of the oral mucosa currents is believed to affect 1-50% of the general population, depending on the method used for diagnosis. The immune system clears most HPV naturally within 2 years (about 90%), but the ones that persist can cause serious diseases. HPV is an essential carcinogen being implicated increasingly in association with cancers occurring at numerous sites in the body. Though there does not occur any specific treatment for the HPV infection, the diseases it causes are treatable such as genital warts, cervical and other cancers.

Abstract
O Papilomavírus Humano - HPV - assume especial destaque na Saúde Pública diante do reconhecimento de sua associação com a ocorrência do câncer uterino, entre outros. Levando em conta a necessidade de implementação de programas de esclarecimentos sobre a prevenção dos agravos relacionados à infecção pelo HPV, coloca-se o propósito da realização do presente diagnóstico sobre conhecimentos e práticas sexuais entre jovens. Direcionando, estrategicamente, para o segmento de universitários, o estudo foi realizado no Campus da Baixada Santista da UNIFESP, estruturado em torno da formação multiprofissional em saúde. O levantamento foi feito a partir da aplicação de questionário em sala de aula, junto aos alunos do primeiro e terceiro ano. Com uma concentração de iniciação sexual na faixa de 15 a 17 anos de idade, os alunos referiram uso de preservativos masculinos associado à preocupação com a contracepção, secundada pela prevenção de Doenças Sexualmente Transmissíveis - DSTs. O conhecimento sobre o HPV foi restrito na população investigada. Embora crescente do primeiro para o terceiro ano, sua apreciação é relativizada quanto ao conhecimento da transmissão, consequências e prevenção. A investigação apontou a necessidade de disponibilizar informações relativas ao HPV em atenção às especificidades da doença.

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
BACKGROUND Human papilloma virus causes benign and malignant abnormalities in different part of the body. The link between high risk types of HPV and some anogenital and aerodigestive tract cancer is well established. Oral HPV infection plays a role in developing oropharyngeal squamous cell carcinoma. We studied the prevalence of oral HPV in healthy individuals and its relative risk factors. METHODS Saliva samples of 114 healthy subjects were collected for HPV DNA analysis. Volunteers completed questionnaires and signed a written consent. For data analysis descriptive statistic, chi square test and odds ratio was used. RESULTS The frequency of oral HPV in healthy individuals was 6.1 %(seven participant).The most frequent type was HPV-18 in five of them. HPV-6 and HPV-66 each was detected in one case. Relation of oral HPV positivity to demographic features and risk factors was not statistically significant. CONCLUSIONS The prevalence of oral HPV infection in our community is the same as many other communities of developing countries, stressing that HPV-18 were the dominant type.

Abstract
A number of reports have investigated the relationship between laryngeal papilloma and human papilloma virus (HPV) infection. On the other hand, it is unclear whether the HPV infection is involved in the occurrence of pharyngeal papilloma. We hypothesized that HPV infection was involved in the occurrence of pharyngeal papilloma similarly to laryngeal papilloma. To verify this hypothesis, we investigated the presence of HPV infection. Furthermore, clinical manifestations of pharyngeal papilloma, which had rarely been reported, were discussed. A male-to-female ratio, solitary or multiple occurrences, and koilocytosis were examined in cases with pharyngeal papilloma. HPV DNA was examined with unfixed surgically resected specimens of pharyngeal papilloma. A screening test by the liquid-phase hybridization method was carried out for the HPV high-risk group (16, 18, 31, 33, 35, 39, 45, 51, 56, 58, 59, and 68) and HPV low-risk group (6, 11, 42, 43, 44). As a control, 15 cases with laryngeal papilloma for which the same screening test was carried out were employed. Pharyngeal papilloma occurred as a solitary lesion more often, whereas laryngeal papilloma occurred as multiple tumors more frequently. The HPV infection rate was 0% in pharyngeal papilloma cases, which was in stark contrast with 66.7% in the HPV low-risk group in laryngeal papilloma cases. Pharyngeal papilloma occurred as a solitary lesion in females more frequently. Contrary to our hypothesis, the involvement of HPV infection was unlikely in the occurrence of pharyngeal papilloma.

Abstract
BACKGROUND Public awareness of human papillomavirus (HPV) as the causal agent of cervical cancer and of the availability of HPV vaccines has increased. As a result, more patients are asking their dentists about oral HPV infection and its prevention by means of vaccination. Parents of pediatric dental patients also may be concerned when their children have HPV-associated oral lesions, because HPV infection still often is considered a purely sexually transmitted disease. In this review, the authors provide the latest information for dental professionals about HPV infection in the oral mucosa and in general. TYPES OF STUDIES REVIEWED The authors searched PubMed for all studies regarding HPV infection in the oral mucosa, and they reviewed relevant publications focusing exclusively on HPV infections of the oral cavity. In selecting studies for review, the authors made a clear distinction between studies regarding HPV infections in the mouth and those regarding HPV infection in the oropharynx or in other head and neck sites. RESULTS HPV can infect oral mucosa. A subgroup of oral cancer clearly is associated with HPV. Oral HPV infection is transmitted sexually but also can be transmitted from mouth to mouth and vertically from an infected mother during delivery. CONCLUSIONS AND CLINICAL IMPLICATIONS Persistent HPV infection in the oral mucosa might increase the risk of developing oral cancer. Regular and meticulous clinical examination is the dentist's most important tool in detecting HPV-associated changes in the oral mucosae. HPV-associated oral cancer may affect a population younger than that typically affected by HPV-independent oral cancer. Alcohol and tobacco use increase the risk of developing oral cancer, so good practice includes encouraging patients to avoid these habits. The available HPV vaccines cover the HPV genotypes found most commonly in the oral mucosa, but their protective effect against oral cancer remains to be elucidated.

Abstract
The link between head and neck squamous cell cancer (HNSCC), especially oropharyngeal cancer, and HPV has become established. HPV16 is the most common genotype in these tumours but HPV6 and HPV11 can also be found in a minority of these cancers, implying that these low-risk HPV types are not entirely benign in the head and neck region. HPV status is also associated with p16 expression and HPV+ tumours are less likely to harbour p53 mutations. HPV DNA is closely associated with poorly differentiated cancers, positive lymph nodes and late-stage disease, which all indicate poor prognosis. Contradictory to this, patients with HPV+ HNSCC seem to have significantly improved response to chemotherapy and radiotherapy as compared with HPV-negative tumours. Interestingly, the risk factors of HNSCC are the same as for HPV, including the number of sexual partners, younger age at first sexual intercourse, practice of oral sex, history of genital warts and younger age.

Abstract
UNLABELLED Human papillomaviruses (HPVs) are a very complex group of pathogenic viruses, with more than 80 types, causing human infection. Given the prevalence of HPV infection and its relationship with the development of cervical and many other cancers, HPV vaccine development has been a major public health initiative worldwide in the last decade. The aim of the presented study was to identify HPV DNA by MY-PCR in 4,150 school children and adolescents, aged 10-18 years in the Wielkopolska region, Poland. All individuals were asked to fill in extensive questionnaires; further normal, oral squamous cells were collected from each pupil. Cellular DNA was isolated and used as a MY-PCR template to estimate the incidence of HPV-active infection. Forty five subjects (1.08% of the sample) were carriers of oropharyngeal HPVs. HPV status and variables of interest, such as age, gender, socioeconomical status, and risk factors (smoking and sexual intercourse history, alcohol consumption) were not correlated. The presence of HPVs in the oral cavity was cumulated in several schools of the region. DNA sequencing of MY-PCR products revealed only four HPV genotypes. The most frequent genotype was HPV11 (38/45 HPV-positive cases), while other more rare genotypes were HPV6 (3/45), HPV12 (3/45), and HPV57 (1/45). CONCLUSION Our findings presented herein, reveal a relatively low prevalance of oropharyngeal HPVs in Polish adolescents and fill an important gap in the knowledge of oral HPV infections of children above 10 years and adolescents.

Abstract
Cancer statistics report an increased incidence of OSCC and OPSCC around the world. Though improvements in screening and early diagnosis have dramatically reduced the incidence of this neoplasm in recent years, the 5-year-disease-free survival, is still poor, specially for oropharyngeal cancer, despite the great scientific and financial efforts. Recently, several papers showed that HPV may be involved at least in the pathogenesis of a subgroup of oral and cervical SCC, leading to distinct molecular characteristics compared with HPV-negative ones. Nevertheless, OPSCCs associated with HPV infection seem to show a better prognosis and affect younger patients (< 40 yrs.), especially females. Therefore, there is the need to properly assess oropharyngeal SCC subgroups: 1) not HPV associated/classic oral SCC: less responsive to anticancer drugs: needs novel post-surgical treatment; 2) HPV associated/oral SCC: needs several management options and suitable "target" therapy against the virus, and/or immune-stimulating therapy. Further issues are: 1) the disclosure of putative targets for more efficient molecular therapy, which may work as cervical cancer post-surgical treatment, in anticipation of the effects of "global prevention" performed by WHO anti-HPV vaccination programs; 2) careful identification of precancerous lesions in both sites; dysplasia is currently treated by excisional or ablative procedures, which don't consider the concept of field carcinogenesis. In fact, it is probable that near or far from an excised precancerous lesion new foci of cell transformation may exist, which are not yet macroscopically evident, but, if detected, would put the patient into a high risk subgroup.Comparing findings reported in the recent literature, the data of this state of the art about HPV might add useful informations concerning oropharyngeal carcinogenesis. Moreover, our review would be useful in order to define novel perspectives of treatment choice for Head & Neck cancer patients, by combining well known chemotherapeutical drugs with new molecular "target" therapy.

Abstract
The aim of our study was to assess the overall trends in the incidence of head-and-neck cancer (HNC) among Danish men and women in 1978-2007, to describe the distribution and incidences of HNCs at different anatomical sites, and to determine whether the incidence of human papillomavirus (HPV)-associated cancers is increasing. Data were extracted from the nationwide Cancer Registry database. To assess the possible impact of HPV infection, the sites of squamous cell carcinomas were categorized as HPV-associated, potentially HPV-associated or HPV-unrelated. In total, 26,474 incident cases were identified and the overall incidence increased throughout the period. Significantly increasing incidence rates were notably seen for tumors in the oral cavity (2.2% per year), tonsils (4.8% per year), oropharynx (3.5% per year) and hypopharynx (4.4% per year). A significantly decreasing incidence of lip cancer was observed among men (-5.0% per year). Cancers at HPV-associated sites (n = 3650) showed strongly increasing incidence rates, primarily in individuals < 60 years. In contrast, HNCs at sites not related to HPV infection showed a significant decrease (in men) or virtually no change in incidence (in women). Our results suggest a marked impact of HPV infection on the epidemiology of HNCs in Denmark. HPV16 is the type most often found in HNCs; thus, the recent introduction of vaccination against HPV may in the future prevent HPV-associated cancers of the head and neck.

Abstract
Genital human papillomavirus (HPV) infection is one of the most commonly diagnosed sexually transmitted infections world-wide. Over the last two decades, research has established a strong causal link between specific types of HPV infection and cancer, particularly cervical, anal, vulvar/vaginal, penile, and oropharyngeal cancer. Limited epidemiological studies of anogenital HPV infection have been conducted in Hispanic populations (including Puerto Rico), and population-based incidence and prevalence estimates of HPV infection among Hispanics are limited. Studies that evaluate knowledge and awareness of HPV among men are also scarce. With the world-wide introduction of two new prophylactic vaccines against high-risk HPVs causing cervical cancer, and the recent FDA approval of the quadrivalent vaccine in preventing genital warts in men, there is an urgency to determine the burden of HPV in Hispanic populations before vaccine programs are implemented on a widespread basis. Knowledge and acceptability of the vaccine prior to implementation of these programs are also necessary to allow a targeted assessment. This review article summarizes existing research on HPV infection and HPV-related morbidities in men, with a particular emphasis on Hispanic men in the United States and Puerto Rico. Three major areas are discussed: (1) genital warts, (2) HPV and related cancers and (3) biobehavioral and psychosocial factors related to HPV infection and vaccination. Specific recommendations for advancing HPV research and knowledge among Hispanic populations also are suggested.
