Abstract
AbstractPersistent infection with high-risk human papillomavirus (HPV) is the main cause of cervical cancer and the prevalence of HPV types varies depending on the geographic region. Therefore, this study assessed the prevalence of HPV types in women with cervical lesions from Sergipe state, Northeastern Brazil. A cross-sectional study was conducted in women with cervical lesions from March to December 2014. These lesions were investigated by PCR and HPV types were identified by DNA sequencing. 432 patients were included, of which 337 patients tested positive for HPV. Eighteen different HPV types were detected, and high-risk HPV types were detected in 69.2%. HPV 16 (63.4%) was the most prevalent HPV type found, followed by HPV 66 (4.6%), HPV 18 (1.6%) and HPV 45 (1.4%). These results highlight the importance of the high prevalence of HPV 66, which is a possibly carcinogenic virus type not covered by the available vaccines. The prevalence of HPV 16 was high in the studied population, reaffirming the importance of young vaccination. However, the high prevalence of HPV 66 found in this study shows the importance of monitoring the diversity of HPV types in different populations and geographic regions to better understand the impacts of current HPV vaccines.

REVISTA BRASILEIRA DE EPIDEMIOLOGIA 2017; 19:160-6.

Abstract
INTRODUCTION Human papillomavirus (HPV) is considered a necessary causative agent for developing oropharyngeal, anal and cervical cancer. Among women in Ecuadorian population, cervical cancer ranks as the second most common gynecological cancer. Not many studies about HPV burden have been published in Ecuador, and genotypes distribution has not been established yet. The little data available suggest the presence of other genotypes different than 16 and 18. OBJECTIVES In the present study, we attempt to estimate the prevalence of HPV 16, HPV 18 and other 35 genotypes among Ecuadorian women undergoing cervical cancer screening. The overall prevalence of HPV infection was also estimated. METHODS Routine cervical samples were analyzed using Linear Array(r) HPV Genotyping test (Roche). RESULTS A total of 1,581 cervical samples obtained from Ecuadorian women undergoing cervical cancer screening were included in this study. HPV DNA was detected in 689 cervical samples (43.58%). Of these samples, 604 (38.20%) were positive for a single HPV genotype, while another 85 (5.37%) samples were positive for multiple HPV types. Genotype 16 (5.50%) resulted in the most frequently detected type in both single and multiple infections. HPV 33 (4.55%) and HPV 11 (3.80%) occupied the second and the third place in frequency among all detected genotypes. CONCLUSIONS Viral genotypes different from HPV 16 and HPV 18 are frequently detected among Ecuadorian women. The overall prevalence of HPV resulted higher than the one reported in other South American countries with a greater burden in the second and third decades of life.

Abstract
BACKGROUND Increasing evidence suggests that human papillomavirus (HPV) intratype variants (specific lineages and sublineages) are associated with pathogenesis and progression from HPV infection to persistence and the development of cervical cancer. OBJECTIVES This study aimed to verify the prevalence of HPV infection and distribution of HPV types and HPV16 variants in southern Brazil in women with normal cytology or intraepithelial lesions. METHODS HPV typing was determined by L1 gene sequencing. To identify HPV16 variants, the LCR and E6 regions were sequenced, and characteristic single nucleotide variants were identified. FINDINGS A total of 445 samples were studied, with 355 from cervical scrapes and 90 from cervical biopsies. HPV was detected in 24% and 91% of these samples, respectively. The most prevalent HPV types observed were 16 (cervical, 24%; biopsies, 57%) and 58 (cervical, 12%; biopsies, 12%). Seventy-five percent of the HPV16-positive samples were classified into lineages, with 88% defined as lineage A, 10% as lineage D, and 2% as lineage B. MAIN CONCLUSIONS This study identified a high frequency of European and North American HPV16 lineages, consistent with the genetic background of the human population in southern Brazil.

Abstract
STATEMENT OF THE PROBLEM Sinonasal papilloma (SNP) is a rare benign lesion characterized by high recurrence rate and malignant transformation. PURPOSE This study aimed to investigate the prevalence of human papilloma virus (HPV) infection in these lesions in South of Iran. MATERIALS AND METHOD In this cross sectional retrospective study, a total of 41 patients, 38 SNP and 3 SNP/Squamous cell carcinoma cases, from 2007 to 2014 were studied. Human papilloma virus (HPV) DNA detection was performed by nested PCR method and positive cases were analyzed for high risk HPV-16 and HPV-18. RESULTS HPV was detected in 31.7%; HPV- 16 in 4.9% and HPV 18 was not detected at all. Dysplastic epithelium was detected in 53% that was not associated with HPV. Three cases were accompanied with malignant transformation that HPV genome was detected in only one case and none of them were positive for HPV16 /18 genomic DNA. CONCLUSION Current research suggests that HPV may be involved in the development of SNP. But the high risk HPV is not important in malignant transformation. More studies are needed to elucidate the possible etiologic mechanism between HPV, inverted papilloma, and squamous cell carcinoma.

Abstract
Human papillomavirus (HPV) infection is common in sexually active women and viral persistence may cause intraepithelial lesions and eventually progress to cervical cancer (CC). The present study aimed to investigate epidemiological factors related to HPV infection and to evaluate viral persistence and CC precursor lesions frequencies in women from a city in the countryside of South Brazil. Three hundred women were recruited from a primary public health care clinic. The patients were interviewed and underwent sampling with cervical brushes for HPV-DNA detection/typing by a PCR-based assay and cytological analysis by Pap smear test. HPV was detected in 47 (15.7%) women. HPV infection was significantly associated with young age (<30 years) and low socio-economic status. Seventeen (5.7%) women presented cytological abnormalities, three of them with precursor CC intraepithelial lesions. A subgroup of 79 women had been previously analyzed and thirteen (16.4%) were persistently infected, two with precursor CC intraepithelial lesions and high-risk HPV types infection (both of them without cervical abnormalities in the first exam). In conclusion, HPV infection was associated with young age (<30 years) and low family income; viral persistence was low (16.4%) but related to CC precursor lesions; and HPV-DNA high risk types detection would help to screen CC in the population.

Abstract
This study aimed to determine the prevalence of high-risk human papillomavirus (HR-HPV) in population of hospital opportunistic screening and to identify the correlation of prevalent genotypes and cervical cytological abnormalities. A cross-sectional study was employed between July 2013 and July 2014 in the Chaoyang hospital, in Beijing. Cervical samples were collected for the Type-specific HPV and the cervical cytological analyses in the population of hospital opportunistic screening. Total of 8975 samples from female patients aged 17-86 years were tested. Of these, 10.4% were infected by HR-HPV, the highest prevalence of HR-HPV in the youngest group and decreasing with aging (X(2)=19.68, P=0.02). Of these, 78.73% were single infections and 21.27% were multiple infections. Age-specific prevalence of multiple HPV exhibited a "U" shaped curve (X(2)=19.98, P=0.018). The most prevalent genotype is HPV 52, then descending order of frequency were HPV-58, 16, 39, 51, 56, 59, 18, 31, 33, 35, 68 and 45. 15.9% had an abnormal cytology in HR-HPV positive women, vs 4.13% in HR-HPV negative women. The prevalence of HR-HPV were 9.2%, 26.8%, 32%, 35.3% and 36.4% in normal cell, ASCUS, LSIL, ASC-H and HSIL, respectively (X(2)=234.67, P=0.000). Women with HPV 52, 16, 18, 58, 39, 51, 59, 56, 33, 31 infections related to the abnormal cytology, while the HPV68, 45, 35 didn't. The prevalent characteristic in population of the hospital opportunistic screening is similar to the population of cervical screen, But the most five prevalent genotype in rank are different .Women with HR-HPV infections were more likely to have the cervical abnormal cytology.
