“…However, when well-informed, 94% were favorable to the vaccination of their sons, what reinforces the need for educative interventions, for the diffusion of information regarding HPV, and for preventive measures. 10 In addition, the Brazilian Ministry of Health offers the cytopathological exam, whose main purpose is the early diagnosis of HPV in women between 25 and 59 years old. However, currently, Brazil does not reach its 80% goal for the target group, according to the World Health Organization (WHO).…”

Objective To evaluate the level of information possessed by pregnant adolescents regarding the human papillomavirus (HPV). Methods Descriptive study developed in the adolescent prenatal outpatient clinic of a tertiary hospital from the state of São Paulo, Brazil. Data were collected between June and December 2017 following approval from the ethics and research committee (CAAE: 1.887.892/2017). Pregnant adolescents, ≤18 years old, who attended the abovementioned outpatient section, composed the sample. Those diagnosed with a psychiatric disorder and those with hearing or cognitive disabilities were excluded. After acceptance to participate in the present study, the pregnant adolescents signed an Informed Consent Form. Regarding the statistical analysis, the chi-squared test and the Fisher exact test were used. Results Regarding the knowledge about HPV, 123 (80.92%) of the participants had already heard about the subject; for 77 (50.66%), their schools had been the source of the information; 101 (66.45%) did not know how they could be infected by the virus. Age variation did not influence their knowledge on how to prevent themselves from HPV (p = 0.2562). The variable vaccine is associated with HPV prevention (p < 0.0001). Conclusion The pregnant adolescents composing the sample have shown to have knowledge about HPV. However, they do not prevent themselves from it appropriately, given that little more than half of the sample was vaccinated, had not reported an understanding that the use of preservatives and vaccination are effective means of prevention, and did not correlate HPV with uterine cervical cancer.

Background: Retinoblastoma is the most common primary intraocular malignancy in children less than 4 years. Retinoblastoma (RB) contains about 3%-5% of all childhood cancers. Recent studies demonstrated that interacting between RB tumor suppressor and oncoproteins of DNA tumor viruses such as human papillomavirus (HPV). The objective of the current systematic review study was to present conducted studies in the field of HPV infection and its possible role in retinoblastoma.Methods: For this systematic review, all relevant original research studies were assessed by searching in electronic databases include PubMed, Embase, Scopus, Google Scholar, and Web of Science by using relevant keywords. The study was designed based on the PRISMA criteria. All publications with English literature and original researches are considered for screening. Results:Conducted search results lead to 4070 studies. The title and abstract screening lead to 11 studies. Data extraction was performed on 8 included studies. The prevalence of the HPV was ranged from 0 to 69%, and HPV genotype 16 and 18 were the most detected types. The most used method for the detection of the viruses was PCR, and the most assessed sample was formalin-fixed, paraffin-embedded tissue blocks. Conclusion:The association between HPV and retinoblastoma is still inconsistent.The prevalence of the HPV in RB was ranged from 0 to 69%, which indicates a wide range and highlights the importance of further investigation for more accurate statistical of HPV prevalence in RB. Thus, further worldwide studies of larger sample sizes of cohorts should be investigated to clarify this uncertainty.

“…Moreover, HPV-related anogenital cancers are increasing worldwide with an estimation of new cases yearly of 13 000, 27 000 and 27 000 for vaginal, vulvar and AC, respectively [ 4 ]. Limited data are available on the impact of HPV and its associated diseases in Mozambique, attesting a high prevalence ranging from 40 to 96% depending on the considered population, and listed the most common and known risk factors, such as multiple sexual partners, reproductive age and other STD, including HIV [ 5 ]. A recent study on women aged 30–49 years showed a prevalence of HPV infection of 23.7% and women living with HIV were twice as likely to test positive for HPV as HIV negative women (39.2 vs. 19.9%) [ 6 ].…”

The burden of cancer is increasing in sub-Saharan Africa due to ageing, common risk factors and population growth. Anal cancer is a human papillomavirus-related rare disease with an incidence rate of 1.8 per 100 000 persons overall with an increasing incidence of by 2% per year in the last three decades. Despite that gold standard management is well described, in low-income countries, there is no possibility for a proper management. We presented a late-stage anal cancer case that reflects the urgent necessity to create the adequate condition for the development of effective oncologic approach including prevention, diagnosis and management.
