OBJECTIVETo observe the correlation between human papillomavirus (HPV) infection and cervical lesion among women living in community of Beijing.

METHODSA total of 795 women at age 20-54, living in Zhanlanlu District of Beijing were screened for cervical lesion. Samples of cervical cytology (LCT) and HPV test (hc2) were collected. Colposcopy and biopsy were conducted in women with positive LCT.

RESULTSIn those 795 women, the infection rate of HPV was 14.1% (112/795). In 40 women who were LCT positive 1 early invasive cervical cancer, 4 cervical intra-epithelial neoplasia (CIN3), 3 CIN2 and 7 CIN1 were noticed. In 750 women with negative LCT, 5 CIN1 and 1 low-grade CGIN were diagnosed. In those women who were Cyto(+) and HPV(+), 15 cases (55.6%, 15/27) were diagnosed with > or = CIN1 (including 7 CIN1, 3 CIN2, 4 CIN3 and 1 early invasive cancer).

CONCLUSIONThe risk of cervical lesion significantly increased in women showing positive in cytology and HPV test.

AIMTo investigate whether urine is a good medium for screening and whether there is a correlation between the amount of extracted DNA and human papillomavirus (HPV)-positivity.

METHODSIn the present study, 30 first-voided urine (FVU) specimens and 20 urethroglandular swabs using cervex-brushes from male partners of HPV-positive patients, and 31 FVU specimens and 100 liquid-based cervix cytology leftovers sampled with cervix-brushes from HPV-positive women were examined for the presence of beta-globin. Oncogenic HPV were detected using type-specific PCR.

RESULTSbeta-globin was found in all the brushed samples, whereas it was found in only 68.9% of the FVU specimens. HPV-PCR was positive in 60.0% of the male brushes, in 29% of the female brushes and in 0% of the male FVU specimens. DNA concentration was, respectively, 0.9998 ng/microL, 37.0598 ng/microL and 0.0207 ng/microL.

CONCLUSIONUrine is not a good tool for HPV detection, probably because the low DNA concentration reflects a low amount of collected cells. beta-globin is measurable in FVU by real time quantitative PCR, but the DNA concentration is lower compared to brush sampling for both genders. beta-globin-positivity of urethral and cervical swabs is 100%, showing a higher mean concentration of DNA, leading to a higher detection rate of HPV. This is the first article linking DNA-concentration to the presence of HPV.

ObjectiveTo investigate the association of circumcision with the incidence of human papillomavirus (HPV) infection in men.

METHODSWe collected the samples from the surface of the coronal sulcus, glans penis, penile shaft and scrotum of 351 males examined for HPV infection in our hospital from January 2016 to August 2017, of whom 118 had received circumcision while the other 233 had not. We compared the incidence rate of HPV infection between the circumcision and non-circumcision groups and analyzed the association of the age of circumcision with the incidence of HPV infection.

RESULTSHPV infection was found in 135 (38.46%) of the males, 29 (24.58%) in the circumcision group and 106 (45.49%) in the non-circumcision group, significantly lower in the former than in the latter (χ² = 14.48, P < 0.01). The incidence rate of HPV infection was also remarkably lower in the males circumcised at ≤17 years (13.16% ［5/38］) than in those circumcised at >17 years of age (30.0% ［24/80］) (χ² = 3.942, P = 0.047).

CONCLUSIONSMale circumcision helps reduce the incidence rate of HPV infection in men and earlier surgery may achieve even better effect.

PURPOSE: Recent reports suggest the association of human papilloma virus (HPV) with retinoblastoma. This study was performed to elucidate whether HPV infection is related to retinoblastoma among Koreans. METHODS: A total of 54 cases diagnosed with retinoblastoma were enrolled from Seoul National University Children's Hospital and Seoul Metropolitan Government-Seoul National University Boramae Medical Center. Presence of human papilloma viral DNA was detected by in situ hybridization in formalin-fixed paraffin-embedded retinoblastoma tissues using both probes against high- and low risk HPV types. RESULTS: The mean age at diagnosis was 22.0 months (range, 1.1 to 98.0 months), and the mean age at enucleation was 27.8 months (range, 1.5 to 112.7 months) among the 54 patients with retinoblastoma. HPV was not detected in any of the retinoblastoma samples using either high risk or low risk HPV probes. CONCLUSIONS: Our study, being the first study in the Korean population, proposes that HPV infection may have no causal relationship with retinoblastoma in Koreans.

OBJECTIVETo review the diagnosis methods and treatment modalities of vulvar intraepithelial neoplasia III (VINIII) and to analyse its prognostic factors.

METHODSThe data of 24 patients with VINIII from 1992 to 2002 were retrospectively reviewed and analysed.

RESULTSAmong these 24 patients, 62.5% (15 patients) were aged less than 40 years and 37.5% (9 patients) over 40 years. Human papillomavirus (HPV) infection was found in 53.3% and 2/9 of these two groups. Treatment modality for all patients was surgical excision including extended local excision (33.3%) and simple vulvectomy (66.7%). 3 patients (12.5%) developed recurrence. Positive resection margin was correlated with recurrence, while age, HPV infection, multifocality and resection modality were not.

CONCLUSIONDuring recent years, the incidence of VIN has been on the increase in younger woman patients which maybe due to the increase of HPV infection, and the data show that the recurrence rate is correlated with positive margin. Treatment should be individualized and either extended local excision or simple vulvectomy is appropriate. Periodical follow-up should be done.

OBJECTIVE: This study was performed to evaluate the clinical performance of APTIMA human papillomavirus (AHPV) assay and Hybrid Capture 2 (HC2) assay in screening for cervical disease, especially in women with atypical squamous cell of undetermined significance (ASC-US) and low-grade squamous intraepithelial lesion (LSIL). METHODS: A total of 411 women diagnosed with ASC-US or LSIL were referred and further triaged by HC2 test. Prior to colposcopy, liquid-based cytology specimens were collected for the AHPV assay. Sensitivity and specificity were established based on the histological findings of cervical intraepithelial neoplasia (CIN). RESULTS: In all 411 subjects, the positive detection rate of AHPV assay was 70.8% (95% confidence interval [CI], 66.4 to 75.2), which was significantly lower than the positive detection rate of 94.9% obtained using HC2 test (95% CI, 92.3 to 96.8). Only one CIN 3-positive case was detected among the 120 AHPV-negative women, which was then confirmed by Pap smear test to be LSIL. The sensitivities of AHPV and HC2 for CIN 3 were similar (94.1% and 100%, respectively). However, AHPV showed a significantly higher specificity than HC2 test (30.2% and 5.3%, respectively; p<0.001). CONCLUSION: AHPV assay is effective in identifying CIN 3-positive cases because of its high specificity and lower false-negative rate. The use of AHPV for the triage of ASC-US and LSIL might help to reduce the referral rate of colposcopy during cervical cancer screening.

OBJECTIVETo evaluate the application value and feasibility of various cervical screening methods and to explore a rapid and efficient cervical cancer screening program for the women in the rural areas of China.

METHODSWe sequentially conducted human papillomavirus (HPV) DNA test by hybrid capture-2 (hc2) with cervical cells, liquid-based thinprep cytology test (TCT), visual inspection with acetic acid (VIA), visual inspection with iodine (VILI), colposcopy respectively for the 2499 married women between 30 and 49 years from Xiushui county of Jiangxi province. All the detection methods were performed independently under double-blind design. Women who were diagnosed positive for having any VIA,VILI and colposcopy inspection or for those women who were diagnosed negative for VIA, VILI and colposcopy but with positive result of HPV or TCT test underwent cervical biopsy directly and endocervical curettage (ECC)when necessary. We performed cervical biopsy endocervical curettage within two weeks to observe the sensitive (SE), specificity (SP), negative predict value (NPV) and positive predict value (PPV) of these detection methods when used alone or combined each other, including HPV test, TCT inspection, VIA, VILI, and colposcopy, the pathological diagnosises of cervical tissue were confirmed by IARC (International Agency for Research on Cancer) while the cytological findings were underegone through the updated program of TBS (The Bethesda System) in 2001.

RESULTSA total of 2499 women underwent the screening and found 443 women who were diagnosed as HPV positive, 337 women with abnormal cervical cytology and 27 women with ASC-H, 157 cases with ASCUS; 103 cases with HSIL, 49 cases with LSIL and 1 cervical cancer. According to the pathological findings. There were 181 women diagnosed as cervical intraepithelial neoplasia (CIN) or cervical cancer, including 81 cases with CIN1 37 cases with CIN2,60 case cervical cancer. The sensitivity rates of HPV, TCT, HPV+ TCT, VIA, VILI, VIA+VILI and colposcopy were 96.67%, 89.47%, 97.98%, 56.57%, 36.36%, 63.64% and 39.39%, and the specificity rates were 85.00%, 96.91%, 86.97%, 94.60%, 96.23%, 92.97% and 98.14% respectively.

CONCLUSIONHPV + TCT seemed to be more sensitive than other screening methods in the cervical cancer screening program.

OBJECTIVETo investigate the epidemiological characteristics of human papillomavirus (HPV) infection in men attending a sexually transmitted diseases (STD) clinic in Hangzhou area.

METHODSMale subjects (n=375) aged 18-70 years, attending the STD clinic were recruited. Urethral swabs were assessed for HPV DNA using polymerase chain reaction (PCR) with the consensus primers MY09/11. HPV genotypes of positive PCR products were determined by restriction fragment length polymorphisms and direct sequence analysis.

RESULTSOf the 375 swabs collected, 305 (81.3%) yielded sufficient DNA for the subsequent HPV analysis. Among the 305 subjects, the prevalence of HPV was 13.8%. Nononcogenic HPV types were found in 8.5% (26/305) of subjects, oncogenic types in 4.3% (13/305), and multiple types in 1.0% (3/305). The prevalence of HPV infection was higher in subjects from urban area than in those from rural area (P < 0.05). The prevalence was also higher in those who received fewer years of education (P < 0.05) and those who had more sex partners (P < 0.05).

CONCLUSIONSHPV infection among men at high risk is not uncommon. The detection rate of HPV DNA is significantly related to some sociodemographic factors, such as residence, educational level and the number of sex partners.
