Background: It is important for dental students to be aware of the HPV vaccination as they are prone to cervical cancer caused due to HPV 16 and 18. HPV can be transmitted through saliva from the patient's oral cavity to the dentist. To evaluate the knowledge, attitude and practices regarding HPV vaccination among dental students in Chennai. Materials and Methods: A self-administered questionnaire was prepared to evaluate the knowledge, attitude and practices regarding HPV vaccination. The questionnaire was circulated among 150 students. Results: 90 students were undergraduates and 60 were postgraduates, p<0.05. 72.7% of the students were aware of HPV vaccination. 45.5% of the students were aware that HPV vaccination is administered against cervical cancer. Only 30% of the students were immunised against HPV. Conclusion: Within the limitations of the study it was found that most of the students were aware of HPV vaccination, although very few were immunised with HPV vaccination.

Purpose Cervical squamous cell carcinoma (SCC) continues to be a significant cause of cancer morbidity and is the third leading cause of cancer-related death in women worldwide. In sub-Saharan Africa, cervical cancer is not only the most common female cancer but also the leading cause of cancer-related deaths in women. Malawi, in particular, has the highest burden of cervical cancer. With the increasing use of human papillomavirus (HPV) vaccination, documenting the prevalent HPV types in those high-risk populations is necessary to both manage expectations of HPV vaccination and guide future vaccine development. Materials and Methods In this study, we performed HPV typing on 474 cervical SCC samples and analyzed the potential impact of HPV vaccination in this population. Results Ninety-seven percent of tumors were positive for at least one HPV type, and 54% harbored more than one HPV type. HPV 16 was the most common type (82%), followed by HPV 18 (34%), HPV 35 (24%), and HPV 31 (12%). A vaccine against HPV 16 and 18 would ideally prevent 53% of cervical SCC, and the nonavalent HPV vaccine (covering HPV 16, 18, 31, 33, 45, 52, and 58) would prevent 71% of cervical SCC in Malawi (assuming 100% vaccine efficacy). The main reason for a lack of coverage was high prevalence of HPV 35, which was also present as a single infection in a small subset of patients. Conclusion Although any HPV vaccination in this population would likely prevent a significant proportion of cervical cancer, the nonavalent vaccine would provide better coverage. Furthermore, investigation of the role of HPV 35 in this population, including possible cross-protection with other HPV types, should be pursued.

Abstract 11 In Myanmar, cervical cancer ranks as the first most frequent cancer among women aged between 15 to 44 years and Human Papillomavirus (HPV) vaccination program is not established yet. Information on HPV genotypes distribution in cervical cancer is crucial to predict the future impact of HPV vaccines. This study aimed to determine the HPV-DNA and genotypes among women with cervical pre-cancer and cancer in Myanmar. A cross-sectional descriptive study was performed in 169 women with cervical neoplasia during 2012 to 2014. After obtaining informed consent, cervical cells were collected from 134 women with cervical intraepithelial neoplasia (CIN) and 35 with squamous cell carcinoma (SCC) of the cervix attending Sanpya General Hospital, Yangon, and Central Women Hospital, Mandalay. HPV-DNA testing and genotyping was performed by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP). HR-HPV was identified in CINI (39.3%), CINII (58.6%), CINIII (66.7%), and SCC (77.1%). Overall, the most common genotypes were HPV-16 (68.1%), followed by HPV-31 (16.5%), HPV-18 (7.7%), HPV-58 (6.6%), and HPV-35 (1.1%). Among SCC, HPV-16 was the most common genotype (66.7%) followed by HPV-18 (14.8%), HPV-31 (11.1%), HPV-35 (3.7%), and HPV-58 (3.7%). In CINI, the most common genotype were HPV-16 (69.7%) followed by HPV-31 (21.2%), HPV-18 (6.1%) and HPV-58 (3.0%). In CINII, HPV-16 was most commonly determined (52.9%) followed by HPV-31 (23.5%), HPV-58 (17.6%), and HPV-18 (5.9%). In CINIII, HPV-16 was also the most common genotype (85.7%) followed by HPV-31 (7.1%) and HPV-58 (7.1%). Vaccine preventable genotype, HPV-16 was the most common genotype in Myanmar. This study highlighted that the establishment of National HPV vaccination program is needed to reduce the incidence and mortality of cervical cancer in Myanmar.[Table: see text][Table: see text] AUTHORS' DISCLOSURES OF POTENTIAL CONFLICTS OF INTEREST: No COIs from the authors.

Introduction: Cervical cancer is the second most prevalent cancer among women in Cameroon. In November 2020, the HPV vaccine was introduced into the expanded programme on immunisation. However, uptake of the vaccine has been slow in the Centre region as opposed to other regions in the country. We therefore sought to describe vaccinators' perception of HPV vaccination in Saa health district.Methods: A self-administered questionnaire with both open-ended and closed questions was used to assess the perception of HPV vaccination among 24 vaccinators from the Saa health district. Quantitative data were summarised as proportions while qualitative data were deductively and inductively coded and thematically analysed.Results: Most vaccinators (75%, n = 18) had a good knowledge about cervical cancer and HPV vaccination. Fourteen (58.3%, n = 14) vaccinators correctly reported the target group, number and spacing of doses for the HPV vaccine. Fourteen (58.3%) vaccinators favoured HPV vaccination while the others (n = 10) were sceptical. Sceptics felt manufacturers hadn't given enough proof of the safety of the vaccine and lacked confidence in government's assessment of the epidemiological situation. The COVID 19 pandemic, fear of infertility and the negative influence of social media were perceived as the main reasons for community hesitancy. Vaccinators criticised health authorities for failing to sensitise the population about the HPV vaccine before its introduction.Conclusion: Vaccinators' perceptions of HPV vaccination may influence the offer of HPV vaccination services. Measures to increase acceptance of HPV vaccination and ownership of the activity among vaccinators have to be put in place.

Recently, there has been a steady growth of cervical cancer all over the world, especially in Russia. Patients with cervical cancer have become much younger. At the same time, the human papillomavirus is not only the main factor in the neoplastic process, but it is also one of the most common sexually transmitted infections in the world. The aim of the paper is to assess the prevalence and characteristics of human papillomavirus genotypes in patients with cervical intraepithelial neoplasia. Materials and Methods. During the periodic screening we examined 213 women of a reproductive age with HPV infection. All patients underwent liquid-based cytology and human papillomavirus genotyping by polymerase chain reaction. Results. We revealed that the prevalence of cervical intraepithelial neoplasia among women with papillomavirus infection was 80.3 % (n=171). According to human papillomavirus genotyping, HPV 16 (38 %) and HPV 33 (32 %) prevailed. We also observed positive high correlation between high-grade squamous intraepithelial lesions (HSIL) and HPV 18 (r=+0.759, p=0.001), a negative mean correlation between HPV 45 and low-grade squamous intraepithelial lesions (LSIL) (r=-0.643, p=0.002). A cohort of patients with severe intraepithelial cervical lesions demonstrated high viral load rates. Conclusion. According to the results obtained, we established the dominance of HPV 16 and HPV 33 genotypes in cervical intraepithelial neoplasia. There were significant differences between HSIL and LSIL patients with HPV 18 and HPV 45. There was also a correlation between an increase in the viral load with the severity of the pathological process. Keywords: human papillomavirus, intraepithelial cervical neoplasms, cervical cancer. В последние годы в мире, особенно в России, наблюдается неуклонный рост и «омолаживание» рака шейки матки. При этом вирус папилломы человека является не только основным фактором прогрессирования неопластического процесса, но и одной из наиболее распространенных инфекций, предаваемых половым путем, в мире. Цель. Оценить распространенность и характеристику генотипов папилломавирусной инфекции у пациенток с цервикальными интраэпителиальными неоплазиями. Материалы и методы. Проведено обследование 213 пациенток репродуктивного возраста с ВПЧ-инфекцией, пришедших на профилактический осмотр. Всем женщинам было выполнено цитологическое исследование жидкостным методом и генотипирование вируса папилломы человека методом полимеразной цепной реакции. Результаты. Распространенность цервикальных интраэпителиальных неоплазий среди женщин с папилломавирусной инфекцией составила 80,3 % (171 пациентка). Согласно данным генотипирования вируса папилломы человека превалировал 16-й (38 %) и 33-й типы (32 %). Выявлена положительная высокая корреляционная связь между цервикальными неоплазиями высокой степени онкогенного риска (HSIL) и 18-м типом ВПЧ-инфекции (r=+0,759 при р=0,001), отрицательная средняя корреляционная связь 45-го типа ВПЧ с низкой степенью онкогенного риска (LSIL) (r=-0,643 при р=0,002). Продемонстрированы высокие показатели вирусной нагрузки в когорте пациенток с тяжелыми внутриэпителиальными цервикальными поражениями. Выводы. По результатам полученных данных установлено доминирование 16-го и 33-го генотипов ВПЧ при цервикальных интраэпителиальных неоплазиях с наличием значимых различий между пациентами с HSIL и LSIL в отношении 18-го и 45-го типов, а также связь роста уровня вирусной нагрузки с увеличением степени тяжести патологического процесса. Ключевые слова: вирус папилломы человека, интраэпителиальные новообразования шейки матки, рак шейки матки.

Backgroud: Cervical cancer is a common disease after breast cancer. That is caused by Human papillomavirus (HPV) and now, we have HPV vaccin to prevent the disease with objectives: to determine rate of correct knowledge, attitudes and practice towards HPV vaccination against cervical cancer of mothers who have daughters aged 1 to 26 years old in An Binh ward, Ninh Kieu district, Can Tho city and to determine the relationship between correct knowledge and correct attitudes and correct behaviors towards vaccination against cervical cancer of these mothers. Materials and method: Cross-sectional, community survey on 410 mothers who are interviewed face to face by using a questionnaire. Results: The rate of correct knowledge, attitude and practice towards HPV vaccination against cervical cancer is 4.4%; 89.5%; 12.2%; respectively. There’s a correlation between correct knowledge and correct behaviors towards vaccination against cervical cancer among mothers (p<0.05), but no correlation between correct knowledge and correct attitudes. Conclusion: the rate of mothers who have correct knowledge and behaviors is relatively low but whose correct attitude is high. Therefore, may be they want to know more information about vaccination against cervical cancer so that it should have appropriate information-education-counseling and health care campaign to community.
