후두유두종은 호흡기계에 발생하는 양성종양중 가장 흔한 질환으로 연령에 따라 소아형과 성인형으로 분류하는데 다발성 병변이 흔하고 재발율이 높다고 알려져 있다. 후두유두종의 원인으로는 human papillomavirus의 감염으로 생각되며 잠복 감염으로 인하여 후두유두종이 재발된다고 알려져 있다. Gissman등에 의해 HPV 11이 발견되었음이 보고된 이래 최근까지 HPV 6와 11이 후두유두종의 원인이 된다고 알려져 있다. HPV의 검출에는 Southern blotting이나 in-situ hybridization 방법이 알려져 있는데 저자들은 현재까지의 바이러스 검색방법 중 가장 예민한 방법인 PCR을 이용하여 후두유두종의 HPV DNA를 조사하여 보고자 한다. 저자들은 1989년 10월부터 1900년 12월까지 서울대병원 이비인후과에서 수술을 시행받은 후두유두종 환자 15예를 대상으로 하였으며 이중 소아형은 9예이었고 성인형은 6예였으며 대부분 다발성 병변이었다. HPV 6는 15예중 10예에서 HPV 11은 15예중 6예에서 발견되었으며 두가지 형이 같이 발견된 경우는 1예가 있었다. 소아형의 경우에는 HPV 6와 11이 각각 5예로 비슷한 비율로 검출된 반면 성인형에서는 HPV 6가 주로 검출되었다.

Human Papillomavirus (HPV) infection is known as the main factor for cervical cancer which is a leading cause of cancer deaths in women worldwide. Because there are more than 100 types in HPV, it is critical to discriminate the HPVs related with cervical cancer from those not related with it. In this paper, the risk type of HPVs using their textual explanation. The important issue in this problem is to distinguish false negatives from false positives. That is, we must find high-risk HPVs as many as possible though we may miss some low-risk HPVs. For this purpose, the AdaCost, a cost-sensitive learner is adopted to consider different costs between training examples. The experimental results on the HPV sequence database show that the consideration of costs gives higher performance. The improvement in F-score is higher than that of the accuracy, which implies that the number of high-risk HPVs found is increased.

To investigate a population-based survey of the prevalence of human papillomavirus (HPV) infection in South Korea, we performed Papanicolaou smears and tests for HPV DNA and anti-HPV antibody detection in 909 sexually active general women (age range; 20-74 years, median 44 years) who were randomly selected residents from S district of Busan City. The presence of DNA of 36 different HPV types was detected by means of a GP 5+/6+ primer-mediated PCR enzyme immunoassay in cervical exfoliated cells, and IgG antibodies against L1 virus-like particles (anti-VLPs) of 5 HPV types 16, 18, 31, 33, and 58 were tested by means of enzyme linked immunoassay. The incidence of cytologic abnormality was 5.2% in Pap smear. The positive rate of HPV DNA was 10.4%, high in young women younger than 35 years old and proportionally increased according to the cytologic grades. The most often found HPV type was HPV 70, followed by HPV 16 and 33, and high-risk HPV types were more frequent in women younger than 35 years old. The most common HPV type in abnormal cytologic smears was HPV 16, followed by HPV 58 and 66. Anti-VLPs was positive in 19.7% and the frequent anti-VLPs type was against HPV 18, followed by HPV 31 and 16. The concordance between the markers for each specific HPV type was noted in 10 women and HPV 16 was the most frequent one. The incidence of multiple HPV infection was 18.9% and that of multiple anti-VLPs antibodies was 31%. Among 103 self-reported virgins, 4.9% had anti-VLP antibodies.

Background: Infections with human papillomavirus (HPV) are highly prevalent among sexually active young women in India. However, not much is known about the incidence of type-specific human papillomavirus (HPV) infections and their patterns of persistence, especially in the Indian context. Objective: The objective of this study was to evaluate the rate of acquisition and persistence of HPV types in young women. Methods: Women residing in an urban slum in Delhi (n=1300) were followed for 24 months at 6 monthly intervals. Exfoliated cervical cells collected at each visit were tested for the presence of HPV DNA. Genotyping was performed using the reverse line blot assay. Results: The incidence rate for any HPV type was calculated to be 5 per 1000 women-months. Among high risk HPV types, HPV16 had the highest incidence rate followed by HPV59, HPV52 and HPV18, i.e., 3.0, 0.58, 0.41 and 0.35 women per 1000 women-months respectively. The persistence rate was higher for high-risk than low-risk HPV types. Among low-risk types, HPV42, HPV62, HPV84 and HPV89 were found to persist. Whereas almost all high risk types showed persistence, the highest rate was found in women with HPV types 16, 45, 67, 31, 51 and 59. The persistence rate for HPV16 infection was 45 per 1000 women-months. Conclusion: Incident HPV infections and high risk HPV type-specific persistence were found to be high in our study population of young married women. Understanding the patterns of HPV infection may help plan appropriate strategies for prevention programs including vaccination and screening.

Background and Objective: Any role of human papillomavirus (HPV) in the development of breast cancer is conjectural. The aim of this study was to investigate possible links between HPV and breast cancer in women, Sanandaj, Iran. Methods: In this case-control study, 70 formalin fixed and paraffin embedded blocks of breast malignant tumors as a case group and 70 blocks of lesions without malignancy were selected as controls. Sections about $10{\mu}m$ thick were prepared. After removing the paraffin, DNA was extracted. Samples were tested by PCR using general and high-risk specific HPV primers. Results: All 70 malignant breast tumors (cases) were invasive ductal carcinomas, and of the 70 controls, 17 (24.3%) were fibrocystic tumors and 53 (75.7%) fibroadenomas. The age range of women in the case group was 25-72 years old and in the control group It was13-66 years. Using HPV general primers two samples were positive in the case group, confirmed to be HPV-18 using high-risk specific primers. Conclusion: No statistically significant association was found between breast cancer and HPV. It is necessary to confirm this result by further investigations in other populations.

To prevent cervical cancer, human papillomavirus (HPV) bivalent and quadrivalent vaccinations are common, but there is a need for a vaccination system based on the high-risk human papillomavirus (HR-HPV) genotype that differs by region. This study aimed to investigate the prevalence of HPV and the distribution of HR-HPV genotypes in 2,014 women who were not vaccinated against HPV. In this study, HPV DNA testing was performed on 2,014 women not vaccinated against HPV and who visited the Busan Obstetrics and Gynecology Department from September 2020 to July 2021. In addition, liquid-based cytology (LBC) test was performed on 493 cases of HR- HPV genotype infection confirmed by HPV DNA test. The prevalence of HPV among women in Busan was positive in 609 (30.2%) out of 2,014 cases. Among the 609 HPV-positive cases, HR-HPV infection accounted for 493 cases (81.0%), which is a high proportion. Of the total 493 HR-HPV infection cases, liquid-based cytology (LBC) was within normal limits (WNL) in 266 cases (54.0%), atypical squamous cells of undetermined significance (ASCUS) in 97 cases (19.7%), low-grade squamous intraepithelial lesion (LGSIL) in 88 cases (17.8%), and high-grade squamous intraepithelial lesion (HGSIL) in 42 cases (8.5%). Single HR-HPV 52 and 16 accounted for the highest and second highest infection rates, respectively. The high infection rate among women aged 18~39 underscores the need for continuous monitoring. In addition, when there were abnormal findings in the cervical epithelium, HPV 52 was the most common, while in the case of HGSIL, HPV 16 was the most common. The HR-HPV genotypes related to cervical cancer should be continuously collected and monitored for use in health policies, including local and national vaccinations.

Purpose: The purpose of this study was to identify predictors of HPV (Human papillomavirus) vaccination among female university students. Methods: The participants in this study were 1,486 female university students. Data were collected using self-administered questionnaire from september 1, 2010 to June 30, 2011. Data were analysed using descriptive statistics, t-test, $x^2$-test and logistic regression. Results: The rate of HPV vaccination was 7.2%. Factors that influence HPV vaccination included residential region, smoking experience, family history of cervical cancer, experience having heard about the HPV vaccination, awareness that HPV is a sexual disease, HPV knowledge, perceived seriousness, perceived benefit and perceived barrier in health beliefs. Conclusion: The results suggest a need to increase HPV vaccination campaigns to increase awareness of HPV vaccination. University and health care facilities should provide health education emphasizing perceived seriousness and perceived benefits. Also, the national health insurance corporation should consider addressing cost issues as a barrier to HPV vaccination.

Objectives: Human papillomavirus (HPV) is the major etiological agent of cervical cancer, a leading cause of morbidity and mortality in women worldwide. Screening strategies for reducing the burden of HPV-mediated carcinogenesis are emerging as an effective means for cervical cancer control and prevention in developing countries. Our study, therefore, aimed to identify HPV infection status in North Indian women during random population screening. Methodology: Cervical/vaginal exfoliated cells and/or Pap smear specimens were collected from 890 women of North Indian ethnicity residing in Lucknow and adjoining areas, during random population screening from June 2009-March 2012. HPV viral loads in clinical specimens were determined by the Hybrid Capture (hc)-2 HPV DNA assay, and subsequently, positive/negative/borderline HPV status was calculated. Results: The HPV incidence in the present study was 11.7%. 751 out of a total of 890 women (84.4%) participating in our HPV screening program were HPV negative (HPV -), 104 (11.7%) tested positive (HPV +) while 35 (3.9%) showed borderline (HPV $^*$) infection status. Furthermore, in the HPV + subjects (N=104), 18 (17.3%) showed strong positivity. We observed that HPV positivity tends to increase with age in North Indian women; the higher the viral load with increasing age, higher is the susceptibility to HPV-mediated cervical cancer. Conclusions: HPV viral load/genotyping may help in identifying women at risk of developing cervical cancer. However, cost-effective HPV screening protocols with a wider population coverage are warranted so as to reduce the burden of cervical cancer in women worldwide in the vaccine-era.
