| prevalence of low and high risk human papillomavirus types in cervical cells from hong kong pregnant chinese using filter in situ hybridization. | filter in situ hybridization, using separate probes for human papillomavirus deoxyribonucleic acid types 6, 11, 16 and 18, was used to determine the prevailing hpv types amongst a group of pregnant chinese women. this group had been previously identified using a mixture of probes for hpv types 6, 11, 16, 18, 31, 33, 35 (virapap). specimens from six of the eleven cases contained one hpv type (55%) while five were positive for two types (45%). the "low-risk" types (hbv6, 11) were identified as fre ... | 1991 | 1654045 |
| human papillomavirus infection in hong kong chinese women with normal and abnormal cervix--detection by polymerase chain reaction method on cervical scrapes. | detection of human papillomavirus (hpv) was accomplished by utilizing polymerase chain reaction methods on cervical scrapes from a total of 488 hong kong chinese women attending the colposcopy, general, and antenatal clinics. from colposcopy clinic, 10% of normal cervix, 31% of condyloma, 56, 50, and 57% of cin i, cin ii, and cin iii, respectively, and 88% of squamous cell carcinoma contain hpv. the overall detection rate is 30%. the most prevalent type is 16. four percent of scrapes from normal ... | 1996 | 8631541 |
| presence of human papillomavirus in esophageal squamous cell carcinomas of hong kong chinese and its relationship with p53 gene mutation. | there is no scientific study that has investigated the association between human papilloma virus (hpv) and p53 mutation in hong kong chinese patients with esophageal cancers. the aim of this survey is to evaluate in details the prevalence and relationship of hpv and p53 mutation in these patients with esophageal squamous cell carcinomas. fresh tissues from the resected specimens of 70 chinese patients (59 men, 11 women) with primary esophageal squamous cell carcinomas (20 well-differentiated, 36 ... | 1997 | 9190999 |
| profile of viral load, integration, and e2 gene disruption of hpv58 in normal cervix and cervical neoplasia. | the clinical utility of viral-load and integration status of human papillomavirus (hpv) infection remains uncertain. we examined 75 women infected with hpv58, a worldwide rare type found to be prevalent in cervical cancers in eastern asia. viral load was significantly higher for cervical intraepithelial neoplasia (cin) 1/2, but those for a normal control group and for cin 3 or cancer overlapped substantially. a pure integrated genome was found for all lesion grades, giving a poor positive predic ... | 2007 | 17703417 |
| the effect of school-based cervical cancer education on perceptions towards human papillomavirus vaccination among hong kong chinese adolescent girls. | objective: to evaluate the effects of school-based cervical cancer education on hong kong chinese adolescent girls. methods: adolescent girls (n=953) in local secondary schools attended a tailored educational program on cervical cancer prevention. self-administered questionnaires were used before and after the program to measure its effects on participants' knowledge, attitude and perceived social norms towards human papillomavirus (hpv) vaccination and their intention to be hpv vaccinated. resu ... | 2010 | 20650592 |
| prevalence and risk factors of human papillomavirus (hpv) infection in southern chinese women - a population-based study. | persistent high-risk type human papillomavirus (hpv) infection is recognized as a necessary cause of cervical cancer. this study aimed to compare the hpv prevalence and risk factors between women residing in hong kong (hk) and guangzhou (gz) region of china. | 2011 | 21559276 |
| prevalence of human papillomavirus, epstein-barr virus, p21, and p53 expression in sinonasal inverted papilloma, nasal polyp, and hypertrophied turbinate in hong kong patients. | background: the purpose of this study of human papillomavirus (hpv), epstein-barr virus (ebv), p21, and p53 in sinonasal inverted papilloma (ip) was to help elucidate its pathogenesis. methods: seventy-three ips, 48 nasal polyps, and 85 hypertrophied turbinates were subjected to hpv polymerase chain reaction (pcr) study. seventy-three ips, 30 nasal polyps, and 32 hypertrophied turbinates were subjected to ebv in situ hybridization (ish), p21, and p53 immunohistochemical (ihc) studies. results: h ... | 2011 | 21608063 |
