  • Background: Most studies of human papilloma virus (HPV) are aimed at the natural history of the infection and its relation to cancer; however, there are few studies to assess knowledge of the general population. Our aim was analyze the degree of knowledge of Argentinians about HPV infection and its prevention. Materials and Methods: We conducted a voluntary, anonymous and non-binding survey with 27 multiple-choice items, in twelve private and public establishments, selected to include a broad population in terms of education, age and gender. The survey consisted of three sections: individual characteristics of the volunteer, HPV infection basic knowledge, its prevention and the virus relationship with other cancers. Results: One thousand two hundred ninety seven volunteers aged 18 to 80 participated. The total number of correct answers was 45.1%. The correct answers for relationship HPV and cervical cancer was 62.1%. Almost 55% did not know about types of HPV that the vaccines for protection. Statistical analysis showed that women, single people, workers, the better educated, those who have had a STDs or HPV and receiving information through medical or educational establishments had greater knowledge of the topic. Only 0.2% of participants answered all questions correctly. Conclusions: Knowledge plays an important role in health care and the deficiency found in our population could influence the success of the measures taken in the fight against cervical cancer. In this regard, we believe it would be appropriate, not only to emphasize early diagnosis and vaccine implementation, but also incorporate new communication strategies, facilitating reception of accurate and precise information by all strata of society.

  • Background:Squamous cell carcinoma(SCC)of the palatine tonsils represents approximately 15-23% of all intraoral SCC. The most frequently reported risk factors for oropharyngeal cancer are smoking and alcohol. In a recent overview of HPV and tonsillar squamous cell carcinoma(TC), 51% contained HPV DNA, and HPV-16 being the most frequent type. We aimed to clarify whether HPV directly effects on the oncogenesis and biologic behavior of TC by comparison with infection prevalence, and physical status of virus. Material and Method:We used HPV genotyping DNA chip(Biocore, Korea, Seoul) arrayed by multiple oligonucleotide probes of L1 sequence of 26 types of HPV and HPV genotypes are identified by fluorescence scanner. The copy numbers of HPV E2 and E6 open reading frames(ORF) were assessed using a TaqMan-based 5'-exonuclease quantitative real-time PCR assay. The ratio of E2 to E6 copy numbers was calculated to determine the physical status of HPV-16 viral gene. Results:We observed a significant difference in HPV prevalence between 52 TCs and 69 CFTs(73.1% vs. 11.6%), and most of the HPVs were type 16(87.2%)and non-episomal(94.1%) state. Conclusions:This study regarding HPV infection prevalence and mechanism in the largest population of palatine tonsillar squamous cell carcinoma with chronic follicular tonsillitis revealed significant difference pf HPV prevalence between TC and CFT. Most of HPV were 16 type and integrated or mixed, HPV-16 integration could be directly related to tonsillar carcinogenesis.

  • The detection of high-risk human papilloma virus (HPV) allows us to predict the presence and future development of cervical intraepitheliallesion. In this study, we compared Hybrid Capture II and DNA chip methods for detection of HPV in cervical swab samples. And we evaluated the clinical efficacy and diagnostic performance of HPV DNA chip and Hybrid Capture II for detecting HPV in cervical neoplastic lesions. Seventy four patients were classified into three groups according to their histologic diagnosis: Group I (nonspecific chronic cervicitis), Group II (low-grade squamous intraepithelial lesion (SIL); koilocytosis, and mild dysplasia), and Group III (high-grade SIL;, moderate, severe dysplasia and in situ carcinoma). Cytologic diagnosis were based on the Bethesda System. Hybrid Capture II and DNA chip methods were performed to detect HPV. In 41 of the 74 cervical samples $(55.4\%)$, HPV DNAs were detected by Hybrid Capture II. In Group III, HPV-positive cases were detected in 15 $(20.3\%)$ of 74 patients by Hybrid Capture II. 25 patients with ASCUS cytology were histopathologically examined: 9 cases $(36\%)$ were Group II. In 18 patients with low-grade SIL cytology, 13 cases $(72.2\%)$ were Group II and 3 cases $(16.7\%)$ were Group III. 12 cases $(92.3\%)$ were Group ill of 13 patients with high-grade SIL cytology. The sensitivity of each test was $82\%$ in Hybrid Capture II and $53.9\%$ in DNA chip test. And the specificity was $74.3\%,\;85.7\%$ in Hybrid Capture II and DNA chip. In conclusion, Hybrid Capture II test is more sensitive than DNA chip in detecting women with cervical neoplastic lesions. Especially, in diagnosing of ASCUS, Hybrid Capture II test is more sensitive. Therefore, Hybrid Capture II test for cancer-associated HPV DNA is a viable option in the management of women with ASCUS.

  • Cervical cancer is one of the leading causes of morbidity and mortality amongst the gynecological cancers worldwide, especially in developing countries. There are few to no initial symptoms and signs. This study was conducted to assess the awareness level of young Pakistani women about cervical cancer and to educate them about this deadly disease. A detailed questionnaire regarding demographic data and information about cervical cancer was distributed in different cities of Punjab. A total of 873 women took part in this survey and 70.1 percent were totally unaware of this cancer. Only 8.5% of the whole surveyed population knew accurately about cancer of cervix, 7% of the surveyed respondents correctly specified the human papilloma virus as the causative agent. Only 5.2% respondents were able to identify the Pap smear test as a diagnostic measure. Out of all the surveyed population only 4.3% of individuals were found to be vaccinated against this disease and the majority was found from the medical profession. Medical professionals, students, working women, housewives and uneducated individuals took active part in this survey. This study demonstrates a low level of awareness among Pakistani women and a need for an active campaign by media and government to increase understanding as well as introducing measures for improved prevention and treatment of cervical cancer.

  • Cervical cancer (CaCx) is the second most fatal cancer contributing to 14% of cancers in Indian females, which account for 25.4% and 26.5% of the global burden of CaCx prevalence and mortality, respectively. Persistent infection with high-risk human papilloma virus (HPV- strains 16 and 18) is the most important risk factor for precursors of invasive CaCx. Comprehensive prevention strategies for CaCx should include screening and HPV vaccination. Three screening modalities for CaCx are cytology, visual inspection with acetic acid, and HPV testing. There is no Indian national policy on CaCx prevention, and screening of asymptomatic females against CaCx is practically non-existent. HPV vaccines can make a major breakthrough in the control of CaCx in India which has high disease load and no organized screening program. Despite the Indian Government's effort to introduce HPV vaccination in the National Immunization Program and bring down vaccine cost, challenges to implementing vaccination in India are strong such as: inadequate epidemiological evidence for disease prioritization, duration of vaccine use, parental attitudes, and vaccine acceptance. This paper reviews the current epidemiology of CaCx and HPV in India, and the current status of HPV vaccination in the country. This article stresses the need for more research in the Indian context, to evaluate interventions for CaCx and assess their applicability, success, scalability and sustainability within the constraints of the Indian health care system.

  • This study was conducted to assess the predictive value of p-glycoprotein (p-gp) and p53 immunoexpression in human papillomavirus (HPV) infected cases of cervical dysplasia. Expression of both p-gp and p53 proteins was detected in cervical smears from 177 squamous intraepithelial lesions (SIL) cases along with 183 "atypical squamous cells of unknown significance" (ASCUS) and 150 normal cases. HPV 16 and 18 infection was detected by polymerase chain reaction using type-specific primers for HPV sub-types. There were no significant detectable p53 and p-gp expression in the normal cervix smears (p>0.05). In the ASCUS group 10 cases were positive for both p53 and p-gp immunoreactivity. In cervical dysplasia cases, p53 was positive in 86 (48.58%) while p-gp was positive in 93 (52.54%) and the two markers showed a highly significant correlation (r=0.92, p<0.001). Expression of p53 and p-gp was associated with grade of SIL (p<0.001). A positive correlation between the presence of HPV and expression of proteins p53 and p-gp in smears of patients with cervical lesions was also noted (p<0.001). Thus, p53 and p-gp immunostaining in cervical smears may act as an auxiliary biomarker for detection of HPV-associated cervical lesions. Additionally, a significant positive correlation between ascending grades of SIL and labeling indices of markers suggests that p53 and p-gp can be used as an adjunct to cytomorphological interpretation of conventional cervical Pap smears.

  • Background: Human papilloma virus (HPV) occurs in women of all age groups, and causes cervical, anal, vaginal, vulvar, penile and oropharyngeal cancers. The aim of the study was to discover what nurses know about HPV infection, testing and vaccination and to determine vaccine practice of their daughters and perceived barriers. Materials and Methods: This cross-sectional and prospective study was carried out nurses who have worked in a hospital between January and June 2014. Pre-test and post-test were used to evaluate the nurses' knowledge about HPV infection, testing and vaccination. This study was performed with nurses who had girls between 9 and 26 years of age for evaluating the behavior of vaccination after three months of education. Results: The mean of pre-test and post-test scores about HPV infection, which included 22 items, were $8.2{\pm}5.6$ and $19.2{\pm}1.5$, respectively. Before education the HPV testing knowledge score was remarkably poor ($1.9{\pm}1.7$ over 5), after education it increased to $4.8{\pm}0.5$. The mean HPV vaccine knowledge score were $3.7{\pm}2.7$ (pre-test) $7.3{\pm}0.8$ (post-test) on a 0-8 scale. The difference between mean total pre-test ($13.9{\pm}9.1$) and post-test ($31.3{\pm}1.9$) scores was statistically significant (p<0.001). After three months of education, only two of the nurses' daughters were vaccinated. The main reason was noted by nurses were not willing to be vaccinated was cost, doubts about safety and efficacy related to the vaccine. About one-third of nurses declared that they would receive the vaccine for their daughter later. Conclusions: Nurses have a crucial role in the prevention, treatment, increasing public awareness and care for population. The education of the nurses about HPV infection, test and vaccination will play an important part decreasing cancer mortality and morbidity.

  • The presence of HPV DNA and the expression of p53 protein and proliferating cell nuclear antigen(PCNA) in head and neck squamous cell carcinoma were determined to evaluate the relationship of these factors and their association with their pathologic stages and cervical lymph node metastasis. Among 65 patients the presence of HPV DNA was found in 12 cases(18.5%), p53 was found positive in 32 cases(49.2%) and expression of PCNA was observed in 24 cases(36.9%). The expression of PCNA was more frequent in the HPV positive cancers compared with the HPV negative ones(p =0.0018), and p53 revealed its higher rate of cooccurrence with the expression of PCNA(p =0.008), which might suggest that PCNA expression has a positive relationship with HPV and p53 mutation in head and neck cancer. There might be inverse relationship between HPV and p53 mutation(p =0.063), but 3 cases showed both HPV DNA positivity and p53 expression. HPV was detected at a higher rate in the early pathologic stages than in the advanced stages of cancer, and p53 expression was more frequently found in the advanced stages(p =0.044). These results suggests that HPV and p53 mutation might have different etiologic roles in the development of head and neck cancer, or cases with p53 mutation might have more aggressive behavior. PCNA expression showed no difference between early and late stages of cancer, and between cases with and without cervical lymph node metastasis.
