Oral and periodontal manifestation related during human papilloma virus infections: Update on early prognostic factors. Heliyon 2024; 10:e31061. [PMID: 38813162 PMCID: PMC11133762 DOI: 10.1016/j.heliyon.2024.e31061] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2024] [Revised: 04/11/2024] [Accepted: 05/09/2024] [Indexed: 05/31/2024] Open
Abstract
Human Papilloma Virus (HPV) is considered one of the most common sexually transmitted infections and has been shown to play an important role in the pathogenesis of squamous cell carcinomas (SCC) of the cervix and head and neck. Manifestations of HPV infections can be manifold, ranging from asymptomatic infections to benign or potentially malignant lesions to intraepithelial neoplasms and invasive carcinomas. The heterogeneity of clinical manifestations from HPV infection depends on the interactions between the viral agent and the host, a direct consequence of the ability on the part of HPV is to remain silent and to evade and convey the action of the host immune system. The oral mucosa represents one of the tissues for which HPV has a distinct tropism and is frequently affected by infection. While much information is available on the role that HPV infection plays in the development of SCC in the oral cavity, there is less information on asymptomatic infections and benign HPV-induced oral lesions. Therefore, the purpose of this review is to analyze, in light of current knowledge, the early clinical and bio-humoral prognostic features related to the risk of HPV malignant transformation, focusing on subclinical conditions, benign lesions, and the correlation between oral infection and infection in other districts. The data show that the main risk associated with HPV infection is related to malignant transformation of lesions. Although HPV-driven OPSCC is associated with a better prognosis than non-HPV-driven OPSCC, primary prevention and early detection of the infection and affected genotype are essential to reduce the risk of malignant neoplastic complications and improve the prognosis.

Evaluation of Oral Squamous Cell Carcinoma Patients Using Polymerase Chain Reaction Regarding the Prevalence of Human Papillomavirus Types 16 and 18. Cureus 2024; 16:e51938. [PMID: 38333435 PMCID: PMC10851917 DOI: 10.7759/cureus.51938] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2023] [Accepted: 01/07/2024] [Indexed: 02/10/2024] Open
Abstract
BACKGROUND Epstein-Barr virus, human papillomavirus (HPV), and herpes simplex virus type 1 (HSV-1) are examples of viruses that have been associated with the development of oral squamous cell carcinoma (OSCC). These viruses can infect various epithelial tissues in the human body. The use of incredibly accurate cellular biology techniques, such as the polymerase chain reaction (PCR), which permits the rapid identification of viruses following infection, has increased. The parameters of human head and neck oncology have been widened. AIM In this study, using the PCR, the presence of HPV variants such as HPV 18 and HPV 16 in patients with OSCC was assessed. MATERIALS AND METHODS Tissue specimens were obtained from clinically presumed OSCC individuals taken as cases, and tissues from the retromolar region were obtained from people who experienced an operation for partially and completely impacted tooth and taken as controls. The study included 80 samples divided into two separate categories: case category (n = 40) = OSCC-diagnosed individuals; control category (n = 40) = controls with a comparable age. For verification of the diagnosis, a specimen of the tissue has been processed and sections have been stained and inspected for standard hematoxylin and eosin stain. Deoxyribonucleic acid (DNA) was extracted from the leftover histopathologically verified tissue specimens and then exposed to PCR for the assessment of HPV infiltration. RESULTS It was observed in this research that 22 cases out of 40 cases of OSCC were found positive for HPV-DNA. While 12 out of 40 age-matched healthy controls were found positive for HPV-DNA. Out of 40 cases of OSCC, 12 cases were found positive for HPV 16. While six out of 40 age-matched healthy controls were found positive for HPV 16. Six cases out of 40 cases of OSCC were found positive for HPV 16. While two out of 40 age-matched healthy controls were found positive for HPV 18. Four cases out of 40 cases of OSCC were found positive for HPV 16. While four out of 40 age-matched healthy controls were found positive for HPV 16 and HPV 18. On carrying out statistical analysis, the variation between the two categories was non-meaningful statistically (p = 0.662). However, the prevalence was greater in the case (OSCC) subgroup. CONCLUSION When evaluated against controls in the current investigation, OSCC cases had a greater level of HPV expression and a greater proportion of HPV 16 positives. However, there was no statistically noteworthy change.

Correlation between Oral Lichen Planus and Viral Infections Other Than HCV: A Systematic Review. J Clin Med 2022; 11:jcm11185487. [PMID: 36143134 PMCID: PMC9501453 DOI: 10.3390/jcm11185487] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2022] [Revised: 09/15/2022] [Accepted: 09/16/2022] [Indexed: 12/11/2022] Open
Abstract
OBJECTIVES This review aimed to evaluate the correlation between viral infections (HPV, EBV, HSV-1, CMV) other than HCV and oral lichen planus to assess if there is sufficient evidence to establish if these viruses can play a role in the etiopathogenesis of the disease. MATERIALS AND METHODS We reviewed the literature using different search engines (PubMed, ISI Web of Science, and the Cochrane Library), employing MeSH terms such as "oral lichen planus" and "OLP" in conjunction with other terms. We utilized the Population, Intervention, Comparison, Outcomes, and Study design (PICOS) method to define our study eligibility criteria. RESULTS A total of 43 articles of the 1219 results initially screened were included in the study. We allocated the 43 selected items into four groups, according to each related virus: HPV, EBV, HSV-1, and CMV. CONCLUSIONS Heterogeneous results neither confirm nor exclude a direct correlation between the investigated viral infections and oral lichen planus etiopathogenesis and its feasible malignant transformation. Many viral agents can cause oral lesions and act as cancerizing agents. Future studies could be desirable to produce comparable statistical analyses and enhance the quantity and quality of the outcomes to promote the translation of research into clinical practice.

Abstract
Objective: The objective of the study was to use polymerase chain reaction (PCR) to examine and compare the genotype distribution of human papillomavirus (HPV) in oral lichen planus (OLP). Materials and Methods: Deoxyribonucleic acid (DNA) was extracted from 20 OLP biopsy specimens. Conventional PCR assay employing consensus HPV primers was used to identify HPV DNA. Positive PCR samples were then subjected to PCR assay with HPV type-specific primers. Results: Out of the total 20 OLP specimens evaluated, eight samples (40%) were positive for HPV. Females had a 41.7% higher HPV-positive rate than males. The most common type in the HPV type-specific PCR assay was HPV-18 (75%), which is a high-risk type of HPV linked to malignant diseases. The erosive kind of OLP had the greatest percentage of HPV positives (50%). Conclusion: The present study confirms the detection of HPV in OLP lesions, as determined by PCR-coupled HPV gene sequencing, as well as its likely mechanism of malignant transformation.

Abstract
OBJECTIVE To determine the persistence of human papillomavirus (HPV) infection following treatment of HPV-positive oropharyngeal squamous cell carcinoma (HPV + OPSCC). METHODS A cross-sectional study was undertaken at The Ottawa Hospital (Ottawa, ON, Canada), a tertiary academic hospital and regional cancer center. Adult patients who were diagnosed with HPV + OPSCC between the years of 2014 and 2016 and treated with curative intent, and who were alive and willing to consent were eligible for inclusion. A saliva assay was used to test for the presence of HPV DNA in a random sample of patients. qPCR was used to amplify DNA from saliva samples. RESULTS Saliva samples were obtained from 69 patients previously treated with HPV + OPSCC. All patients had a minimum of 2 years of follow-up. 5 patients tested positive for HPV: 2 were positive for HPV-16, 2 for HPV-18, and 1 "other" HPV type. No patient in our study cohort had suffered recurrence post-treatment. CONCLUSIONS This study is the first to demonstrate the prevalence of persistent oncogenic HPV DNA in saliva following treatment for HPV + OPSCC. This prevalence appears to be low, despite the fact that persistent HPV infection is a precursor for the development of HPV + OPSCC. This finding raises questions about what factors influence the clearance or persistence of HPV DNA in saliva after treatment for HPV + OPSCC, and may add to our understanding about the longitudinal effects of HPV infection in these cancers.

Abstract
Background Oral cancer is often preceded by a mucosal lesion called an oral potentially malignant disorder (OPMD). Many plant-derived compounds are of value in medicine. The objectives of this study were to develop a soluble mucoadhesive film containing α-mangostin (α-MG), a compound extracted from the peel of mangosteen fruit, and determine its activities against oral cancer cells, against human papillomavirus type 16 (HPV-16) pseudovirus, and its anti-inflammatory properties. Methods A soluble mucoadhesive film containing α-MG was prepared. Oral squamous carcinoma cell line (SCC25), murine macrophage cells (RAW264.7), and human gingival fibroblast cell line were cultured. Anticancer activity and viability of SCC25 cells in response to α-MG film solution were determined by MTT assay. HPV-16 pseudovirus was constructed and effects of the film solution on attachment and post-attachment steps of the infection were investigated. Anti-inflammatory activity was assessed by nitric oxide (NO) inhibition. Fibroblast cell migration was determined by in vitro scratch assay. Results The soluble α-MG film showed cytotoxic effects on SCC25 cells in concentration > 125 µg/ml with IC50 of 152.5 µg/ml. Antiviral activity against HPV-16 pseudovirus was observed at attachment step, but not at post-attachment step. The film also possessed a strong anti-inflammatory effect and promoted wound healing without cytotoxicity. Conclusions Mucoadhesive film containing α-MG has a cytotoxic effect on oral squamous carcinoma cell line and an inhibitory effect on HPV-16 pseudovirus at attachment step. The α-MG film also shows a potent anti-inflammatory activity and enhances wound healing. Thus, the soluble α-MG film may have a potential role in treating oral cancer.

Abstract
Human papilloma virus infection (HPV) is the most common sexually transmitted disease. Little is known about male infection. Nonavalent vaccine against types 6/11/16/18/31/33/45/52/58 was approved and neutral gender immunization programs have been proposed. This study evaluates the potential impact of nonavalent vaccine compared to quadrivalent in male living in Sicily (Italy). 58.7% of samples were HPV positive and forty-four types of HPV were identified. A significant higher estimated coverage of nonavalent vaccine than quadrivalent was observed (64.3% vs. 45.8%), with absolute and relative additional impact of 20.1% and 47.2%, respectively. Low impact of the vaccine were calculated as the empirical probability of HPV genotypes 6/11/16/18/31/33/45/52/58 alone or in combination; the high impact as empirical probability of HPV6/11/16/18/31/33/45/52/58 genotypes alone or in association with other genotypes. The potential impact of the nonavalent vaccine vs quadrivalent was significant for low and high impact (29.7% > 18:8%; 34:6% > 26.6%, respectively). Particularly, in men with lesions and risky sexual contact was significant only for low impact (35.5% > 29.7%; 31.4% > 19.7%, respectively). In partners with positive females was significant for low impact (26.3% > 15.1%) and high impact (33.7% > 23.2%). Nonavalent vaccine offers broader protection in men with HPV positive partners, who would have a potential role in the transmission of the infection.

Abstract
Papillomavirus (PV) infection is associated with development of epithelial cancer in different species, including domestic cat (Felis catus). Felis catus PV type-2 (FcaPV-2) is considered the causative agent of a proportion of feline cutaneous squamous cell carcinoma (SCC), through the transforming properties of its E6 and E7 oncogenes. However, the possible role of FcaPVs in the aetiology of feline oral SCC (FOSCC) is still unclear. The aim of this study was to assess the presence and gene expression of FcaPV-2 in FOSCC samples. We detected FcaPV-2 DNA in 10/32 (31%) of the analysed FOSCC by the use of PCR methods. Importantly, viral mRNA was detected by RT-PCR in 7/10 (70%) of DNA positive samples. In particular, FcaPV-2 L1, E2 and E6E7 genes were found to be expressed in 5/10 (50%), 3/10 (33%) and 5/10 (50%) samples, respectively. Viral DNA was also detected in non neoplastic oral ulcerative lesions (ULs) (4/11, 36%); qPCR suggested a difference in viral load between ULs and FOSCCs, particularly in those expressing E6E7, although it was not statistically significant. These data suggest, but do not definively prove, a possible role of FcaPV-2 in the development of a proportion of FOSCC. Moreover, L1 and E2 gene expression results indicate that FcaPV-2 infection associated with these tumours may possibly be productive.

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
Objective: The diverse subset of oral squamous cell carcinoma (OSCC) with different clinical appearance and outcome, independent of traditional risk factors has led to increasing attention in human papillomavirus (HPV) infection. Materials and Methods: The investigation followed a case–control design. Information pertaining to the subjects was retrieved from hospital records. Twenty cases of OSCC and twenty age-matched controls were analyzed to ascertain the prevalence of HPV types 16 and 18. DNA was extracted from the blocks of formalin-fixed paraffin embedded tissues, and HPV-DNA was amplified using HPV type-specific primers by polymerase chain reaction (PCR) method. Data analysis was carried out using Chi-square test. Results: HPV-DNA was detected in 55% of cases (11/20; HPV 16 = 6, HPV 18 = 3 and HPV 16 and 18 = 2) and 30% of controls (6/20; HPV 16 = 3, HPV 18 = 1 and HPV 16 and 18 = 2) indicating higher percentage of HPV presence among OSCC cases. No significant association was found between the presence of HPV and gender, age, site and grade of differentiation of OSCC. Conclusion: Although the presence of HPV was higher in cases compared to controls, none of these differences were statistically significant. HPV 16 and 18 are commonly found in normal oral mucosa mandating the need for distinguishing clinical, subclinical and latent HPV infections.

Abstract
Context: Oral leukoplakia (OL) is a well-recognized precancerous lesion with various etiological factors. Most commonly deleterious oral habits such as tobacco smoking and viral etiologies mainly human papillomavirus (HPV) play an important role. p53 polymorphisms mostly homozygous Arginine (Arg) allele has a greater risk of degradation by HPV. Hence, HPV infection and p53 polymorphisms may act as synergistic factors for increased the risk of malignant transformation in oral precancerous lesions. Aims: The aim of this study is to evaluate the risk of OL and its malignant transformation due to infection by HPV and p53 polymorphisms in the oral biopsy samples through polymerase chain reaction (PCR). Subjects and Methods: A total of 40 individuals were involved– 10 individuals were controls without deleterious habits, 15 were controls with deleterious habits, and 15 were with histologically confirmed OL individuals with deleterious habits. PCR and restriction fragment length polymorphism using sma1 enzyme were carried out to evaluate the expression of HPV and p53 polymorphisms. Statistical Analysis Used: Chi-square test, Fischer's exact t-test, and odds ratio. Results: (1) HPV DNA expression was higher in Leukoplakia individuals than controls. (2) p53 genotype with homozygous Arg was more in HPV-infected individuals. Conclusions: To conclude HPV infected OL cases were mostly with Arg/Arg type of p53 polymorphism.

Abstract
Background The role of human papilloma virus (HPV) in oral lichen planus (OLP) is controversial. Objectives The primary aim of the current study is to calculate the pooled risk estimates of HPV infection in OLP when compared with healthy controls. Methods Bibliographic searches were conducted in three electronic databases. Articles on the association between HPV and OLP were selected from case-control studies or cross-sectional studies, following predefined criteria. Pooled data were analyzed by calculating odds ratios (OR) and 95% confidence interval (CI). Results Of the 233 publications identified, 22 case-control studies met the inclusion criteria. Collectively, 835 cases and 734 controls were available for analysis. The summary estimate showed that OLP patients have significantly higher HPV prevalence (OR: 6.83; 95% CI: 4.15–11.27) than healthy controls. In subgroup analyses, the association of HPV and OLP varied significantly by geographic populations. The ORs ranged from 2.43 to 132.04. The correlation of HPV and erosive-atrophic oral lichen planus (EA-OLP) (OR: 9.34) was comparable and well above that of HPV and non-EA-OLP (OR: 4.32). Among HPV genotypes, HPV 16 showed an extremely strong association with OLP (OR: 11.27), and HPV 18 showed a relatively strong one (OR: 6.54). Conclusion In conclusion, a significant association was found between HPV and OLP. The strength of the association varied across geographic populations, clinical types of OLP, and HPV genotypes. The results suggest that HPV might play an important causal role in OLP and in its malignant to progression.

Abstract
Objectives: Oral cancer ranks third among all cancers in the Indian population. Human papilloma virus (HPV) plays a significant role in oral carcinogenesis. Population-based subtype variations are present in the HPV prevalence. This study gives an emphasis on the parameters to be considered in formalin fixed paraffin embedded tissues for polymerase chain reaction (PCR)-based research work. Materials and Methods: Cross-sectional study on archival paraffin-embedded tissue samples of oral squamous cell carcinoma (OSCC), epithelial dysplasia, and normal oral mucosa surrounding impacted tooth was amplified by PCR for the E6 gene of HPV type 16 and E1 gene of HPV type 18. Results: HPV 18 was positive in three OSCC cases. There was no statistically significant association of the positivity of HPV with the age, gender or habit. The HPV positive patients had a tobacco habit and were of a younger age group. Conclusion: The presence of HPV in carcinomatous tissue highlights the possible role of HPV in carcinogenesis and archival paraffin embedded tissue specimen can be used for this analysis. Recent studies on genomic analyses have highlighted that the HPV positive tumors are a separate subgroup based on genomic sequencing. The results of a larger retrospective study will help further in our understanding of the role of HPV in carcinogenesis, this study could form the baseline for such follow-up studies.

Abstract
BACKGROUND Infection with human papillomavirus (HPV) is necessary for the development of cervical carcinoma. By contrast, the role of HPV in the pathogenesis of other malignancies, such as head and neck cancers, is less well characterised. This study aimed to address key information gaps by conducting a systematic review and meta-analysis of the prevalence of HPV infection in head and neck cancers, focusing on data for European populations. METHODS MEDLINE, Embase and grey literature sources were systematically searched for primary studies that were published in English between July 2002 and July 2012, and which reported on the prevalence of HPV infection in head and neck cancers in European populations. Studies on non-European populations, those not published in English, and those assessing patients co-infected with human immunodeficiency virus were excluded. Eligible studies were combined in a meta-analysis. In addition, the potential statistical association between the head and neck cancers and certain HPV types was investigated. RESULTS Thirty-nine publications met the inclusion criteria. The prevalence of HPV of any type in 3,649 patients with head and neck cancers was 40.0% (95% confidence interval, 34.6% to 45.5%), and was highest in tonsillar cancer (66.4%) and lowest in pharyngeal (15.3%) and tongue (25.7%) cancers. There were no statistically significant associations between the HPV types analysed and the geographical setting, type of sample analysed or type of primer used to analyse samples in head and neck cancers. CONCLUSIONS The prevalence of HPV infection in European patients with head and neck cancers is high but varies between the different anatomical sites of these malignancies. There appears to be no association between HPV type and geographical setting, type of samples analysed or type of primer used to analyse samples in such cancers.

Abstract
BACKGROUND Human papilloma virus oral infection can be related to several factors including HIV infection, cigarette smoking, marijuana consumption and number of sexual partners. We conducted a study on oral HPV prevalence and clearance among the hosts of the San Patrignano community, a population considered at "high-risk" for HPV due to their previous habits. METHODS From March 2007 to September 2010 all subjects were submitted to oropharyngeal brushing and saliva collection at baseline, after 6, 12 and 48 months (for subjects HPV positive at baseline). Samples were analyzed to detect HPV DNA and virus genotypes. The correlation between HPV prevalence and demographic, behavioral or immunological characteristics was assessed. RESULTS Among 194 subjects, 30 (15%) were HPV positive with 25 (13%) high-risk (HR)-HPV at baseline brushing. At 12 months HPV infection was cleared in all cases. However at 48 months HPV was newly detected in 33% of subjects. A correlation between time spent in the community and increase in the ratio of "low-risk" (LR) HPV and HR-HPV was observed. HPV infection was not associated with age, gender, HIV status, HCV, alcohol and/or drug exposure, number of years spent in community, sex with drug-addicts and condom use. Only AIDS under antiretroviral treatment was inversely correlated with the risk of infection. CONCLUSIONS At 1 year a complete HPV clearance was observed which could be related to adoption of healthier lifestyles of participants. New HPV infections were detected even in the absence of the recognized and declared risky behavioral factors, suggesting a re-expression from a latent infection.

Abstract
OBJECTIVE To investigate the presence and persistence of human papillomavirus (HPV) infection in the oral mucosa of patients with head and neck squamous cell carcinoma (HNSCC), and its correlation with prognosis. STUDY DESIGN HPV infection was characterized in tumors and pre and posttreatment oral scrapings in 51 patients with HNSCC and matched controls using the SPF10 LiPA Extra assay. p16INK4A immunostain and in situ hybridization for high-risk HPV genotypes recognized transcriptionally active infection in tumor samples. The risk of infection was compared in patients and controls. The association of pretreatment HPV status with recurrence and survival and with posttreatment HPV persistence was assessed. RESULTS Oral HPV infection risk was significantly higher in patients with HNSCC than in controls (P < .001). Oral HPV infection was associated with infection in the first posttreatment scrapings (P = .015), but did not affect recurrence or prognosis. CONCLUSION Oral HPV infection is frequent in patients with HNSCC and has no prognostic implications, suggesting that posttreatment polymerase chain reaction monitoring on oral cells is not effective to monitor patient recurrence risk.

Abstract
The critical factors and etiological role of human papillomavirus (HPV) infection in the development of female bladder tumor were examined. Eighty-four female patients with primary bladder tumor were studied. After DNA extraction from each paraffin-embedded tissue, HPV-DNA and genotype were checked. In cases of all HPV-positive cases and some HPV-negative cases, in situ hybridization (ISH) for high-risk HPV-DNA, and immunohistochemical analysis for p16-INK4a were performed. HPV-DNA was detected in 5 (6.0%) of 84 eligible patients, and HPV16 was detected in 3 patients, and HPV6 and HPV52 was detected in one case, respectively. HPV-DNA was detected frequently in younger patients and in patients with a history of cervical cancer. In four high-risk HPV-positive cases, high-risk HPV-DNA was present in tumor tissues, and p16-INK4a was expressed moderately or strongly. Two cases had a past history of cervical cancer. In these 2 cases, the same HPV type (HPV16) was detected from bladder tumor and cervical cancer. High-risk HPV-DNA ISH signals and p16-INK4A expression were also detected widely in these cervical cancer tissues. HPV infection is likely to play an important role in the development of female bladder tumor at younger cases with a past history of cervical cancer.

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.

Exfoliated cells of the oral mucosa for HPV typing by SPF10 in head and neck cancer. J Virol Methods 2012; 186:99-103.

Abstract
HPV infection in the superficial cells of the oral mucosa could reflect the presence of HPV in head and neck cancer cells. Due mostly to the use of heterogeneous analytical methods, discordant data exist in the literature regarding the agreement between the presence of HPV in non-neoplastic oral mucosa and in tumour tissue from the same patient. The presence of HPV DNA and viral types were compared in paired cytological and biopsy samples from 56 patients with head and neck neoplastic and preneoplastic lesions using the highly sensitive SPF10 LiPA Extra assay, which has been validated recently for formalin-fixed paraffin-embedded tissue using paired cervical cytology and biopsy samples. Kappa statistics were used to measure the inter-rater agreement. The overall agreement with respect to HPV infection was 96.43% (kappa=0.8367). For 76.79% of subjects (kappa=0.6937), the same number of HPV types was detected in cytological and biopsy specimens. The overall positive typing agreement was 90.90%, comprising 130 out of 143 individual HPV type analyses. The agreement shown was good for HPV 18, 44, 45, 54 and 66 (kappa=0.6585-0. 7321), excellent for HPV 6, 16, 40, and 54 (kappa=0.8108-0.8679), and absolute for HPV 11, 31, 33, 35, 39, 51, 52, 53, 59, 74, and 69-71 (kappa=1.0000). The high sensitivity of the SPF10 LiPA and its excellent performance both for recognising HPV infection and for identifying the viral types present in tumour tissue and in oral exfoliated cells make it a useful method for the assessment of HPV infection in patients with head and neck cancer. The excellent agreement for HPV infection and genotyping in paired samples suggests that oral exfoliated cells can be used for HPV detection in the head and neck region.

Abstract
INTRODUCTION Adequate brushing of oral mucosa is important for accurate human papillomavirus (HPV) detection in potentially malignant (oral leukoplakia [OL], oral lichen planus [OLP]) and malignant (oral squamous cell carcinoma [OSCC]) lesions. Since various factors may limit the adequacy of oral brushing and, consequently, the accuracy of HPV detection, modified sampling procedures should be evaluated for their effect on HPV frequency and/or types detected. AIM To compare the HPV frequency in samples obtained by brushing the lesion site with the frequency in samples obtained by brushing an apparently normal adjacent site. The correlation between HPV frequency and keratinization of the site affected by the lesion, as well as sociodemographic variables (age, sex, smoking and drinking habits), was also examined. METHODS HPV DNA was detected in brushing samples from 50 patients with OL, 49 with OLP, and 17 with OSCC. Polymerase chain reaction (PCR) amplification was performed by MY09/MY11 and GP05+/GP06+ primers; the HPV type was identified by DNA sequencing and a reverse hybridization (line probe) assay. Data were analyzed by the Z test, the Fisher's exact test, the chi-square test, odds ratio (OR), and a logistic regression model. RESULTS HPV DNA was detected in 22% of samples from lesion sites and in 16% of samples from adjacent sites (p = 0.22) in patients with OL, in 24.5% and 22.4% of samples from lesion and adjacent sites, respectively, in patients with OLP (p = 0.40), and in 35.3% and 41.2% of samples from lesion and adjacent sites, respectively, in patients with OSCC (p = 0.36). Lesions adjacent to HPV-positive normal sites had an increased rate of HPV detection (OR = 30; 95% CI 9.57, 94.1). HPV-18 was the most frequent genotype, followed by HPV-6, -16, -33, and -53. HPV prevalence was reduced in lesions at keratinized sites (14.5%) compared with non-keratinized sites (34.4%; p = 0.007; OR = 0.32; 95% CI 0.13, 0.81). DISCUSSION In patients with OL, OLP, or OSCC, a high prevalence of HPV infection was shown in apparently normal sites adjacent to lesion sites infected by HPV. The lower HPV frequency in lesions at keratinized sites suggests that HPV detection by lesion brushing is affected by keratinization. The keratinized epithelium may be less susceptible to HPV infection or, alternatively, the highly proliferative activity in non-keratinized sites may predispose to HPV infection. CONCLUSION Results from this study indicate that taking samples from normal sites adjacent to oral lesions may be of value in HPV detection, particularly when the lesions are located at keratinized sites. This sampling procedure may allow more accurate diagnosis of HPV infection compared with sampling only the lesion site, and may also represent a reliable method to investigate the biological characteristics of HPV infection and related oral carcinogenesis.

[PMID: 22498489 DOI: 10.1016/j.oraloncology.2012.03.002] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2011] [Revised: 03/02/2012] [Accepted: 03/02/2012] [Indexed: 11/16/2022]
Abstract
BACKGROUND HR HPV infection was proposed as aetiological factor of oral squamous cell carcinomas (OSCC). HPV frequency in OSCC is highly variable, due to the discrepancy in oral sampling procedures, HPV testing methods and inclusion criteria regarding tumour site (strictly oral cavity vs. nearby structures). Our aim was to compare HPV DNA frequency and type-specific distribution in paired cytological and histological samples of SCC strictly located in oral cavity. The correlation between HPV detection rate by each method of sampling and demographical, behavioural and clinical-pathological variables was also examined. PATIENTS AND METHODS HPV DNA was detected in brushed cells and formalin-fixed paraffin-embedded biopsies obtained from 83 consecutive unselected immunocompetent adults with OSCC. HPV DNA detection was performed in all samples by nPCR followed by direct DNA sequencing and the assay INNO-LiPA HPV Genotyping. Univariate and multivariate statistics were used, including Cohen κ index to evaluate agreement between two methods and association between HPV infection and demographical, behavioural and clinical-pathological variables for each method of sampling (p<0.05 statistically significant). RESULTS HPV DNA was detected in 15.7% (13/83) of brushings and 12.1% (10/83) of biopsies (p>0.05). High risk HPV 51, 16 and 39 were genotypes more frequently detected, especially among biopsies; no concordance between two methods was found (Cohen κ index=0.04, p=0.34). CONCLUSION A fraction of OSCC could be linked to HR HPV infection in the Mediterranean area. Although without a statistical significance, biopsy specimen demonstrated more accurate for HR HPV detection than brushing in OSCC.

Abstract
INTRODUCTION Human papillomavirus (HPV) is an important risk factor for oropharyngeal cancer. Individuals with human immunodeficiency virus (HIV) have higher oral HPV prevalence but the risk factors for oral HPV infection are not well understood for either HIV-positive or HIV-negative individuals. METHODS This study was nested within the Multicenter AIDS Cohort Study (MACS; men) and Women Interagency HIV Study (WIHS; women) cohorts. Exfoliated oral epithelial cells were collected from 379 HIV-positive and 266 at-risk HIV-negative individuals using a rinse and gargle with Scope mouthwash. Samples were tested for 36 types of HPV DNA using PGMY09/11 consensus primers and reverse line blot hybridization. Risk factors for oral HPV infection were explored using logistic regression with generalized estimating equations in this cross-sectional analysis. RESULTS Prevalent oral HPV infection was common (34%), including HPV16 infection in 5.7% of participants. HIV-positive individuals had increased odds of prevalent oral HPV infection compared with HIV-negative individuals [adjusted OR = 2.1; 95% confidence interval (CI), 1.6-2.8]. Risk factors for prevalent oral HPV differed in HIV-positive and HIV-negative participants. Among HIV-negative individuals, higher number of recent oral sex or rimming partners were strong risk factors for prevalent oral HPV infection (each P(trend) < 0.01). In contrast, among HIV-positive individuals, lower CD4 T-cell count (P(trend) < 0.001) and higher number of lifetime sexual partners (P(trend) = 0.03) were strong risk factors. CONCLUSIONS Oral HPV prevalence was elevated in HIV-positive individuals after controlling for differences in cigarette smoking and sexual behavior, supporting the possibility that HIV may affect the natural history of oral HPV. IMPACT Immunosuppression may contribute to increased persistence or progression of oral HPV infection.

Abstract
Background There is increasing evidence for the role of High Risk (HR) Human PapillomaVirus (HPV) in the pathogenesis of Oral Squamous Cell Carcinoma (OSCC). The E6 and E7 oncogenes from HR HPVs are responsible for the deregulation of p53 and pRB proteins involved in cell cycle and apoptotic pathways. In cell lines experiments, the HPV E7 protein seems to be able to enhance Hypoxia Inducible Factor-1 alpha (HIF-1α) activity, normally involved in the response to hypoxia and able to enhance angiogenesis. Results We studied tumor specimens from 62 OSCC; a higher prevalence of tumors in TNM stage II and also in pT2 class between OSCC infected positive HPV16 DNA than non-infected ones was observed. HIF-1α positivity was detected throughout the analysed fields, not associated with areas of necrosis and also observed in cells immediately adjacent to blood vessels. A significant increase in mean values of the HIF-1α labeling indexes was observed for pT1-T2, as well for stage I-II, in the infected positive HPV16 DNA tumors than non-infected ones. HIF-1α and HPV16 E7 labeling indexes showed a significantly positive correlation which suggested a positive association between HPV16 E7 and HIF-1α expression. Conclusions In our specimens HIF-1α immunoreactivity hints for an O2-independent regulatory mechanism in infected positive HPV16 DNA tumors, especially for pT1-T2 and stage I-II tumors, suggesting a very early involvement in the development of HPV-induced OSCC. HIF-1α and HPV16 E7 labeling indexes suggest also a positive association between the two proteins in infected positive HPV16 DNA OSCC.

Human papillomavirus types 16 and 18 in epithelial dysplasia of oral cavity and oropharynx: a meta-analysis, 1985-2010. Oral Oncol 2011; 47:1048-54.

Abstract
Human papillomavirus (HPV) types 16 and 18 are causally related to a sub-set of oral cavity and oropharyngeal squamous cell cancers. However, a clear estimate of the prevalence of HPV-16/18 in oral cavity and oropharyngeal dysplasia (OOPD) is not available. This literature review and meta-analysis was conducted to provide a prevalence estimate for HPV-16/18 in OOPD. Twenty-two studies that reported prevalence of HPV-16 and/or 18 in 458 OOPD lesions were analyzed. Meta-analysis was used to evaluate the prevalence of HPV-16/18 and logistic regression was used for stratified analysis by age, gender, and histological grade. The overall prevalence of HPV-16/18 in OOPD lesions was 24.5% [95% confidence interval (CI), 16.4-36.7%)]. The individual prevalence for HPV-16 alone was 24.4%. The prevalence of HPV-16/18 in oral cavity lesions alone was 25.3% (95% CI, 14.2-45.2%). The odds of detection of HPV-16/18 in dysplastic lesions in males were twice that of females [odds ratio (OR), 2.44]. HPV-16/18 were 3 times more common in dysplastic lesions (OR, 3.29; 95% CI, 1.95-5.53%) and invasive cancers (OR, 3.43; 95% CI, 2.07-5.69%), when compared to normal biopsies. There was no significant difference in HPV-16/18 rates between dysplastic lesions and cancers or between mild, moderate or severe dysplastic lesions. This meta-analysis provides a quantification of the prevalence of HPV types 16/18 in OOPD lesions. These results also support the assumption that HPV-16/18 infection occurs during the early phase of the oral cavity and oropharyngeal carcinogenesis.

Abstract
BACKGROUND Oral cancer is the sixth most common malignancy in developed countries, representing almost 3% of malignant tumors. Tobacco use and alcohol consumption are well-established risk factors. However, the observation that most patients with oral cancer have not been exposed to these risk factors suggests that additional causes may promote oral carcinogenesis. A link has been suggested between human papillomavirus (HPV) and oral cavity cancer but the significance of HPV contribution to oral carcinogenesis as well as the prevalence of HPV infection in normal oral cavity mucosa remains debated. METHODS In this study, the prevalence of oral HPV infection was evaluated in 81 randomly selected Northern Italian subjects with clinically normal oral mucosa using a nested PCR on DNA extracted by oral smears. RESULTS AND CONCLUSIONS No HPV-related lesions were detectable in any of the smears analyzed by cytological approach. nPCR identified HPV DNA in only one (1.2%) of the specimens obtained from clinically healthy oral mucosa and subsequent characterization assigned the positive case to HPV type 90. These data suggest that the incidence of HPV infection in the healthy population might be very low and that other risk factors are likely responsible to promote oral carcinogenesis.

Abstract
OBJECTIVES Human papillomavirus (HPV) in oral carcinoma (OSCC) and potentially malignant disorders (OPMD) is controversial. The primary aim was to calculate pooled risk estimates for the association of HPV with OSCC and OPMD when compared with healthy oral mucosa as controls. We also examined the effects of sampling techniques on HPV detection rates. METHODS Systematic review was performed using PubMed (January 1966-September 2010) and EMBASE (January 1990-September 2010). Eligible studies included randomized controlled, cohort and cross-sectional studies. Pooled data were analysed by calculating odds ratios, using a random effects model. Risk of bias was based on characteristics of study group, appropriateness of the control group and prospective design. RESULTS Of the 1121 publications identified, 39 cross-sectional studies met the inclusion criteria. Collectively, 1885 cases and 2248 controls of OSCC and 956 cases and 675 controls of OPMD were available for analysis. Significant association was found between pooled HPV-DNA detection and OSCC (OR = 3.98; 95% CI: 2.62-6.02) and even for HPV16 only (OR = 3.86; 95% CI: 2.16-6.86). HPV was also associated with OPMD (OR = 3.87; 95% CI: 2.87-5.21). In a subgroup analysis of OPMD, HPV was also associated with oral leukoplakia (OR = 4.03; 95% CI: 2.34-6.92), oral lichen planus (OR = 5.12; 95% CI: 2.40-10.93), and epithelial dysplasia (OR = 5.10; 95% CI: 2.03-12.80). CONCLUSIONS The results suggest a potentially important causal association between HPV and OSCC and OPMD.

Abstract
Squamous cell carcinoma is the most frequent malignant tumour of the oral cavity. It is widely known that tobacco and alcohol consumption are the major causes of the development of oral squamous cell carcinoma (OSCC). The human papilloma virus infection has also been postulated as a risk factor for squamous cell carcinoma, although conflicting results have been reported. The aim of this study is to evaluate the presence of high-risk and low-risk type human papillomavirus in a large sample of squamous cell carcinoma limited to the oral cavity by means of quantitative real-time polymerase chain reaction. Data were obtained from 278 squamous cell carcinoma limited to oral cavity proper. Sequencing revealed that 5 samples were positive for HPV type 16, 5 for HPV type 11, and 1 for HPV type 6. Human papillomavirus 11 was detected in 5 tumours out of the 278 examined. The prevalence rate for Human papillomavirus 11 was 1.8% (C.I. 0.7–3.9). The matched case-controls analysis indicated that the prevalence among controls did not significantly differ with respect to cases and that Human papillomavirus 11 alone did not correlate with squamous cell carcinoma.

Abstract
BACKGROUND Nasopharyngeal carcinoma (NPC) is a malignant tumor which arises in surface epithelium of the posterior wall of the nasopharynx. There's is evidence that Epstein Barr virus (EBV) is associated to NPC development. However, many epidemiologic studies point to a connection between viral infections by the human papillomavirus (HPV) and NPC. METHOD Seventy Moroccan patients with NPC were screened for EBV and HPV. EBV detection was performed by PCR amplification of BZLF1 gene, encoding the ZEBRA (Z Epstein-Barr Virus Replication Activator) protein, and HPV infection was screened by PCR amplification with subsequent typing by hybridization with specific oligonucleotides for HPV types 16, 18, 31, 33, 35, 45 and 59. RESULTS The age distribution of our patients revealed a bimodal pattern. Sixty two cases (88.9%) were classified as type 3 (undifferentiated carcinoma), 6 (8.6%) as type 2 (non keratinizing NPC) and only 2 (2.9%) cases were classified as type 1 (keratinizing NPC). EBV was detected in all NPC tumors, whereas HPV DNA was revealed in 34% of cases (24/70). Molecular analysis showed that 20.8% (5/24) were infected with HPV31, and the remaining were infected with other oncogenic types (i.e., HPV59, 16, 18, 33, 35 and 45). In addition, statistical analysis showed that there's no association between sex or age and HPV infection (P > 0.1). CONCLUSION Our data indicated that EBV is commonly associated with NPC in Moroccan patients and show for the first time that NPC tumours from Moroccan patients harbour high risk HPV genotypes.

Abstract
BACKGROUND Fanconi's anemia (FA) is a rare recessive genetic disorder characterized by bone marrow failure, developmental and congenital abnormalities, which frequently evolves to aplastic anemia and neoplasias, primarily acute leukemia and head-neck carcinomas. Risk of malignancies increases after hematopoietic stem cell transplantation (HSCT), and the role of human papillomavirus (HPV) in FA carcinogenesis have been proposed. OBJECTIVE To investigate prevalence of oral HPV in FA patients without oral malignant lesions. MATERIALS AND METHODS After oral examination, 76 subjects without detectable oral malignant lesions were included and classified in four groups: 20 FA submitted to HSCT (I), 22 FA not submitted to HSCT (II), 18 severe aplastic anemia (SAA) submitted to HSCT (III) and 16 healthy subjects (IV). Liquid-based cytology sampling, HPV screening by polymerase chain reaction and genotyping by reverse hybridization were performed. RESULTS The HPV detection rates were: group I 35%, group II 27.3%, group III 38% and group IV 6.25%. Prevalence of high risk HPV types, mainly HPV16, was detected. Compared with control group, suggestions for increased likelihood of being HPV infected in SAA (OR = 9.55, 95% CI: 1.01-125.41) and FA patients submitted to HSCT (OR = 8.08, 0.83-72.29) emerged. CONCLUSION Patients without oral malignant lesions submitted to HSCT, have high prevalence of oral HPV. HPV screening and close follow up should be considered in these patients.

Abstract
Background Previous studies have either investigated the relationship of HPV with oral cancer or the prevalence of HPV on the oral cavity. The purpose of this investigation was to study the prevalence of HPV in oral cavity of women with oral sex practices and cervical lesions. Methods Forty six (46) non-smokers and non-alcoholic patients attended the "Clínica de Displasias" of "Ciudad Juarez" were sampled. This population had a CIN diagnosis sometime between the previous six months. On previous consent they filled out a questionnaire related to their oral sex practices. Afterwards one swab from cheeks and another from palate/gum were taken; PCR was used to determine generic HPV, HPV16 and HPV18. Results Seventy two percent (72%) of the patients stated to have oral sex practices regularly which all of them were positive to HPV either in oral mucus, palate/gum or both. The total of the given results showed that 35% had HPV16; among those distributed in 26% with regular oral sex practices and 9% stated as never practiced oral sex. An association was found between oral HPV16 positivity and progression to cervical CIN advanced lesions. On the other hand HPV18 was not detected. The frequency of HPV16 was higher in buccal mucosa (23%) versus palate/gum (16%). Conclusions This study suggests that buccal HPV16 infection is associated with CIN progression.

Abstract
BACKGROUND The authors elucidated an etiologic role of human papillomavirus (HPV) infection in carcinoma of the bladder. METHODS One hundred seventeen of 224 patients with bladder carcinoma who were treated between 1997 and 2009 were enrolled in this study. The presence of HPV DNA was tested on frozen carcinoma tissues that were obtained by transurethral resection using a polymerases chain reaction-based method. Localization of HPV was observed on archival tissue specimens by in situ hybridization (ISH) for high-risk HPV DNA. Cyclin-dependent kinase (CDK) inhibitor 2A (inhibits CDK4) (p16-INK4a) and minichromosome maintenance protein-7 (mcm-7)-surrogate markers for high-risk HPV-E7 oncoprotein-and HPV-L1 (capsid) protein expression were evaluated by immunohistochemistry. RESULTS HPV types 16, 18, 31, 33, 52, and 58, and an unknown HPV type were detected in 18 of 117 samples (15%) from patients with bladder carcinoma. HPV16 was identified in 6 samples, HPV18 was identified in 4 samples, and HPV33 was identified in 3 samples. All were single HPV type infections. HPV was detected in 38% (12 of 28) of histologic grade 1 bladder carcinomas, 8.5% (6 of 71) of grade 2 bladder carcinomas, and in 0% (0 of 18) of grade 3 bladder carcinomas. Multivariate analysis indicated that younger age (<60 years; odds ratio [OR], 10.9; 95% confidence interval [CI], 2.6-45.3) and grade 1 tumors (OR, 4.5; 95% CI, 1.2-17.0) were associated with HPV infection. ISH analysis indicated that high-risk HPV DNA was localized in the nuclei of tumor cells of all HPV-positive samples. p16-INK4a and mcm-7 were expressed in 94% and 89% of HPV-positive carcinoma cells, respectively. HPV-L1 protein expression, which suggested reproductive HPV infection, was not observed in any carcinoma. CONCLUSIONS The current results indicated that high-risk HPV is likely to be a causative agent of some low-grade bladder carcinomas that develop in younger patients.

Abstract
Human papillomaviruses (HPVs) seem to play an important role in the pathogenesis of gynecological carcinomas and in head and neck carcinomas. The aim of this study was to detect and genotype HPVs in fresh oral squamous cell carcinoma (OSCC) from a Sardinian population, and to determine whether HPV presence was significantly associated with the development of OSCC. The oral mucosa tissues were obtained from 120 samples (68 OSCC and 52 control samples) taken from a Sardinian population seen at the Dental Clinic of the Department of Surgery and Odontostomatological Sciences, University of Cagliari (Italy) and the “ Ospedale SS Trinità”, Cagliari (A.S.L. 8) between 2007 and 2008. PCR was used for the detection of HPV DNA and the genotype was determined by DNA sequencing. The frequency of HPV infection was evaluated in relation to age, sex, smoking and alcohol use. Statistical analysis was performed using the SPSS 11.5 software. The results showed the presence of HPV-DNA in 60.3% of OSCC with HPV-16 (51.2%) being the most frequent genotype. In these Sardinian OSCC patients, HPV-DNA was detected more in males (65.8%) than in females (34.1%) while controls show a 0% of HPV presence. HPV positive was highly associated with OSCC among subjects with a history of heavy tobacco and alcohol use and among those with no such history. A greater frequency of high risk HPV presence was observed in patients with OSCC compared to health control patients. In addition these results suggested that oral HPV presence could be associated in OSCC subjects. Our results need more analyses to detect the HPV-DNA integration into tumoral cells.

Abstract
There is considerable debate within the literature about the significance of human papilloma virus in head and neck squamous cell carcinoma, and its potential influence on the prevention, diagnosis, grading, treatment and prognosis of these cancers. Cigarette smoking and alcohol consumption have traditionally been cited as the main risk factors for head and neck cancers. However, human papilloma virus, normally associated with cervical and other genital carcinomas, has emerged as a possible key aetiological factor in head and neck squamous cell carcinoma, especially oropharyngeal cancers. These cancers pose a significant financial burden on health resources and are increasing in incidence. The recent introduction of vaccines targeted against human papilloma virus types 16 and 18, to prevent cervical cancer, has highlighted the need for ongoing research into the importance of human papilloma virus in head and neck squamous cell carcinoma.

Abstract
PURPOSE The purpose of this study was to evaluate the role of HPV and p53 polymorphisms in oral squamous cell carcinomas (OSCC) affecting Malaysian population. METHODS We analysed frozen samples from 105 OSCC as well as 105 oral specimens derived from healthy individuals. PCR assays targeting two regions of the virus were used. PCR amplification for the analysis of p53 codon 72 arginine/proline alleles was carried out in a separate reaction. RESULTS HPV DNA was detected in 51.4% OSCC samples, while 24.8% controls were found to be HPV positive. HPV was found to be significantly associated with OSCC (P < 0.001, OR = 4.3 after adjustment for habits) when compared to controls. High-risk HPV was found to be significantly associated with OSCC cases (P < 0.05). Demographic profiles of age, gender, race and habits were not associated with HPV presence in cases and controls. However, significantly less HPV positivity was seen in poorly differentiated compared to well-differentiated OSCCs. No significant association was found between HPV positivity and p53 polymorphisms in cases and control groups. Additionally, we found no association of codon 72 polymorphism with oral cancer. CONCLUSIONS This study indicates that high-risk HPV infection is one of the contributing factors for OSCCs. HPV 16 was the predominant type found in Malaysian patients with OSCC. Further, we did not find any association between p53 codon 72 polymorphism and HPV infection or between the p53 polymorphism and the risk of oral cancer.

Abstract
BACKGROUND This study describes the histopathological, immunohistochemical (IHC) and in situ hybridization (ISH) data of 25 cases of oral ulcers in HIV-positive patients, with clinical and microscopical features similar to ulcers not otherwise specified (NOS)/necrotizing ulcerative stomatitis (NUS). METHODS Sex, age and clinical history were obtained from the clinical records. Histological analysis for H&E, Gomori-Grocott and Ziehl-Neelsen stains, IHC analysis to detect infectious agents and to characterize inflammatory cellular infiltrate, and ISH for cytomegalovirus (CMV) and EBER1/2 were performed. RESULTS Twenty-one patients were men and four were women (mean age of 34.6 years). The tongue was preferentially affected. Microscopically, the lesions showed extensive necrosis, leukocytoclasia, vasculitis with luminal fibrin clots and an intense inflammatory cellular infiltrate predominated by CD68(+) atypical large cells, normal-sized and crescent-shaped nuclei macrophages, interspersed by CD8(+) T lymphocytes. Mast cells were also observed in all samples studied. CD4(+) T lymphocytes, CD20(+) B lymphocytes and VS38c(+) plasma cells were practically absent. CMV and EBER1/2 were identified in scarce cells of 3 and 16 of 25 cases respectively. CONCLUSION These results show that CD68(+) macrophages, followed by CD8(+) T lymphocytes, were the predominant inflammatory cells, indicating they are relevant to the pathogenesis of the ulcers, possibly reflecting an abnormal immune response in the oral mucosa. The clinicopathological and immunoprofile features of the present cases are similar to NOS ulcers/NUS in HIV-positive patients.

Abstract
Head & Neck Cancer (HNC) represents the sixth most common malignancy worldwide and it is historically linked to well-known behavioural risk factors, i.e., tobacco smoking and/or the alcohol consumption. Recently, substantial evidence has been mounting that Human Papillomavirus (HPV) infection is playing an increasing important role in oral cancer. Because of the attention and clamor surrounding oral HPV infection and related cancers, as well as the use of HPV prophylactic vaccines, in this invited perspective the authors raise some questions and review some controversial issues on HPV infection and its role in HNC, with a particular focus on oral squamous cell carcinoma. The problematic definition and classification of HNC will be discussed, together with the characteristics of oral infection with oncogenic HPV types, the frequency of HPV DNA detection in HNC, the location of HPV-related tumours, the severity and prognosis of HPV-positive HNC, the diagnosis of oral HPV infection, common routes of oral infection and the likelihood of oro-genital HPV transmission, the prevention of HPV infection and novel therapeutic approaches.

Abstract
This study investigated the presence of human papillomavirus (HPV) DNA and viral types in 33 cases of oral squamous cells carcinoma (OSCC) and compared the immunohistochemical expression of the cell-cycle markers p21 and pRb between cases of the disease with and without HPV. DNA was extracted from paraffin-embedded tissue and amplified by PCR for the detection of HPV DNA. Viral typing was performed by dot blot hybridization. Immunohistochemistry was performed by the streptavidin-biotin technique. HPV DNA was detected in 11 (33.33%) of the 33 cases. The prevalent viral type was HPV 18 (81.81%). A significant association was observed between the presence of HPV and immunohistochemical expression of pRb, but not between p21 expression and the presence of the virus. The low frequency of detection of HPV DNA in OSCC suggests a possible participation of the virus in the development and progression of only a subgroup of these tumors.
