Abstract
BACKGROUND Genital warts are important causes of morbidity and their prevalence and incidence can be used to evaluate the impact of HPV vaccination in a population. METHODS We enrolled 1020 women in a prospective cohort study in Nigeria and followed them for a mean (SD) of 9 (4) months. Nurses conducted pelvic examinations and collected ectocervical samples for HPV testing. We used exact logistic regression models to identify risk factors for genital warts. RESULTS The mean age of study participants was 38 years, 56% (535/962) were HIV-negative and 44% (427/962) were HIV-positive. Prevalence of genital warts at enrolment was 1% (4/535) among HIV-negative women, and 5% (23/427) among HIV-positive women. Of 614 women (307 HIV negative and 307 HIV positive women) for whom we could compute genital wart incidence, it was 515 (95% CI:13-2872) per 100,000 person-years in HIV-negative and 1370 (95% CI:283-4033) per 100,000 person-years in HIV-positive women. HIV was associated with higher risk of prevalent genital warts (OR:7.14, 95% CI:2.41-28.7, p < 0.001) while higher number of sex partners in the past year was associated with increased risk of incident genital warts (OR:2.86, 95% CI:1.04-6.47. p = 0.04). HPV11 was the only HPV associated with prevalent genital warts in this population (OR:8.21, 95% CI:2.47-27.3, p = 0.001). CONCLUSION Genital warts are common in Nigeria and our results provide important parameters for monitoring the impact of future HPV vaccination programs in the country. HIV infection and number of sexual partners in past year were important risk factors for prevalent and incident genital warts respectively.

Abstract
OBJECTIVE Human papillomaviruses (HPV) are etiologically associated with the development of virtually all genital warts. HPV-6 and HPV-11 are the most commonly detected HPV genotypes, but at least 20 other HPV genotypes have occasionally been found in genital wart tissue specimens. STUDY DESIGN The aim of this study was to determine from 100 genital wart tissue specimens collected from female patients using multiplex gap-PCR technique the prevalence of various genital HPV among women with HPV genital warts in south of Iran. 100 genital wart tissue specimens were tested for the presence of HPV PG5/PG6 and also for HPV type using polymerase chain reaction (PCR). RESULTS Based on the collected data, 73 (73 %) samples were detected positive for HPV DNA and 23 (23 %) samples out of 100 samples were detected negative for HPV DNA. 49 (49 %) and 67 (67 %) of patients were detected positive for HPV type 6 and 11, respectively. There was a significant association between marital status and HPV genotype 6 (OR = 0.51, 95 % CI = 0.37-0.70, P = 0.01). Nevertheless, no significant association was found between marriage and HPV genotype 11 (OR = 0.85, 95 % CI = 0.58-1, 24, P = 0.7). Similarly, this result was demonstrated, in combined marriage and HPV-general (OR = 0.80, 95 % CI = 0.62-0.05, P = 0.4). CONCLUSION Concerning the prevalence of HPV in our study, determination of genital HPV prevalence and multiple infections among the normal population of women of Hormozgan Province is recommended.

Abstract
OBJECTIVES The national seroprevalence of the nononcogenic human papillomavirus (HPV) type 11, one of the types targeted by the quadrivalent HPV vaccine, has not been evaluated in the United States. The objectives of this study were to estimate the national seroprevalence and evaluate predictors of HPV-11 seropositivity. STUDY DESIGN We tested serum samples for HPV-11 antibodies and analyzed questionnaire data from the second phase of the National Health and Nutrition Examination Survey III, 1991--1994. Seroprevalence estimates were weighted to represent the US population. RESULTS : Overall seroprevalence of HPV-11 infection was 4.7%. Seroprevalence was significantly higher among females (5.7%) than among males (3.6%). Independent predictors of HPV-11 seropositivity included sex, race/ethnicity, lifetime number of sex partners, education, and HPV-16 seropositivity. CONCLUSION This study represents the most comprehensive picture of HPV-11 infection in the United States to date, and provides baseline data on the prevalence of HPV-11 before availability of the quadrivalent HPV vaccine.

Abstract
To clarify the causal relationship between human papillomavirus (HPV) and cervical intraepithelial neoplasia (CIN), we analyzed 386 unfixed biopsy specimens by blot hybridization at Tm -40 degrees C, targeting 38 skin and 42 genital HPVs. By the recognition of PstI, BanI, and MspI cleavage patterns, single genital, but no skin's HPVs were identified with more than 10 copies per cell in 354 CIN (88 CIN I, 94 CIN II, and 172 CIN III). HPVs 40, 42, 43, 54, 62, or 71 was found in 10 CIN I, while HPVs 18, 30, 39, 51, 56, 59, 66, 68, 69, or 82 was found in 35 CIN I, 20 CIN II, or 8 CIN III. On the other hand, HPVs 16, 31, 33, 35, 52, 58, or 67 was identified in 43 CIN I, 74 CIN II, or 164 CIN III. The results are strongly indicative that most genital HPVs have potency to induce CIN I; however, HPV 16 and its closely related types are able to efficiently induce CIN III. We discuss the definition of causal HPV for CIN with regard to viral prevalence and viral load.

Abstract
Recurrent respiratory papillomatosis (RRP) is a potentially devastating disease that can have significant morbidity, and can even result in mortality due to airway compromise or, less commonly, malignant transformation. Two distinct types of RRP exist: adult-onset RRP (AO-RRP) and juvenile-onset RRP (JO-RRP). Acquisition of human papillomavirus (HPV), the causative agent of RRP, is believed to occur in the peripartum period in the case of JO-RRP, with disease symptoms (primarily hoarseness) becoming apparent during the first several years of life. Treatment currently consists of surgical debulking of the papillomas to relieve airway obstruction. However, numerous antiviral therapies have also been evaluated, albeit primarily under uncontrolled settings. This article will review the biology, natural history and management of HPV infection, with particular emphasis on JO-RRP.

Abstract
Thirty-nine patients with condylomas (12 women and 27 men) attending a dermatology clinic were tested for genital human papillomavirus (HPV) DNA and for seroprevalence to HPV type 6 (HPV6) L1 virus-like particles. The L1 consensus PCR system (with primers MY09 and MY11) was used to determine the presence and types of HPV in sample specimens. All 37 (100%) patients with sufficient DNA specimens were positive for HPV DNA, and 35 (94%) had HPV6 DNA detected at the wart site. Three patients (8%) had HPV11 detected at the wart site, and one patient had both HPV6 and -11 detected at the wart site. Thirteen additional HPV types were detected among the patients; the most frequent were HPV54 (8%) and HPV58 (8%). Baculovirus-expressed HPV6 L1 virus-like particles were used in enzyme-linked immunosorbent assays to determine seroprevalence among the patients with warts. Seronegativity was defined by a control group of 21 women who were consistently PCR negative for HPV DNA. Seroprevalence was also determined for reference groups that included cytologically normal women who had detectable DNA from either HPV6 or HPV16 and women with HPV16-associated cervical intraepithelial neoplasia. Among the asymptomatic women with HPV6, only 2 of 9 (22%) were seropositive, compared with 12 of 12 (100%) female patients with warts. A similar trend in increased HPV6 seropositivity with increased grade of disease was found with the HPV16 DNA-positive women, whose seroprevalence increased from 1 in 11 (9%) in cytologically normal women to 6 in 15 (40%) among women with cervical intraepithelial neoplasia 1 or 3. However, only 4 of 25 (16%) male patients were seropositive. No factors examined, such as age, sexual behavior, or a history of warts, were found to definitively account for the gender difference in seroresponse.

Abstract
We have established a critical identification method for the full spectrum of genital human papillomaviruses (HPVs) in clinical specimens. It was based on the recognition of PstI, BanI and MspI cleavage patterns of HPV DNA detected by blot hybridization with HPV 58 DNA probe at Tm -40 degrees C. By this method, we identified 24 different types of genital HPV including 5 novel types (HPV 59, 61, 62, 64 and 67) in the specimens collected at one hospital and found almost all the HPVs with the authentic cleavage patterns of their respective prototypes. In 235 cervical biopsy specimens, HPV 6 or 11 was found in exophytic condyloma acuminatum (15/15) but not in any cervical intraepithelial neoplasia (CIN) specimens. In contrast, HPV 18, 30, 43, 54, 56, 59, 62, 66 and 67 were identified in CIN I (28/71) or II (4/56) but not in CIN III, while HPV 16, 31, 33, 35, 39, 51, 52 and 58 were identified in CIN III (83/93) as well as in CIN I (34/71) and II (47/56). The result indicates that heterogeneous genital HPVs prevail all over the world. In addition, HPV 6 and 11 are etiologic agents only of exophytic condyloma, whereas the other HPVs are etiologic agents of CIN with the segregation of specific HPVs in CIN III. We propose a new clinicopathologic grouping of genital HPVs founded on nucleotide homology of the HPV genome.

Abstract
We established a murine monoclonal antibody (K1H8) to human papillomavirus (HPV) using alkaline-disrupted virions of HPV type 1 (HPV-1) as the immunogen. K1H8 recognized a 57 kD capsid protein of HPV-1 and detected the antigen in paraffin sections of formalin-fixed tissue. With K1H8, we examined immunohistochemically 68 biopsy specimens obtained from the female genital tract. The specimens were histologically condyloma acuminatum or koilocytotic lesions with or without dysplasia and each specimen was found to harbour a single type of genital HPV, such as types 6, 11, 16, 18, 31, 33, 42, 51, 52, 56, and 58, by Southern blot hybridization analysis. The antigen was localized in the nuclei and occasionally in the cytoplasm of squamous cells showing koilocytotic changes. Eighty-four per cent of the specimens (57 cases) showed positivity for the antigen, indicating that K1H8 is a broadly-reactive antibody to various genital HPVs. The results suggest that benign mucosal lesions of the female genital tract are more frequently associated with viral production and are a potential source of transmission.

Abstract
In a plantar cyst composed of the wall of the squamous cell layer and the horny inner substance in the lower dermis, we found characteristic pathological changes, such as cytoplasmic eosinophilic inclusions and vacuolated structure, and, immunohistochemically, the papillomavirus capsid antigen. The human papillomavirus (HPV) DNA cloned from the cyst showed no homology with other known prototypes of HPV (HPV 1 through HPV 59) by Southern blot analysis under stringent conditions and was named as HPV 60. HPV 60 DNA was found in three other cases of plantar cyst with the identical pathological changes, but not in a plantar cyst without such changes. The results suggest that HPV 60 has unique biological properties to induce a plantar cyst as a distinct type of cutaneous HPV.

Abstract
Immunosuppressed patients such as transplant recipients are known to develop multiple lesions suggestive of human papillomavirus (HPV) infection. A giant anal condyloma was obtained from a transplant patient; several fragments taken from different areas were examined for the presence of HPV DNA using in situ hybridisation, polymerase chain reaction (PCR) and Southern blot. Typical koilocytes were seen in routinely stained tissue sections, suggesting an HPV infection; furthermore, group specific HPV antigen was detected in one of four frozen fragments. Different results were obtained by in situ hybridisation according to the fragment tested. HPV types 6/11 were detected in each of the five fragments, frozen or fixed in Bouin's or formalin solutions. However, the number of HPV DNA positive cells and the intensity of the reaction greatly varied with the specimen. HPV 16 and 18 probes also reacted positively with the sample fixed in formalin; a stronger signal was observed with HPV 18 in one large focus than with HPV 16. HPV type 5 was detected in a few isolated cells of two frozen fragments. With the Southern blot technique, the profile of an HPV 6/11 was seen only in one of two frozen fragments; in this case, the bands were intense. A slight positive reaction was also obtained in one frozen fragment with HPV 16 probe. Four frozen fragments were analyzed with PCR: HPV 6/11 was detected in each fragment; HPV 18 was detected in the four samples but with different intensities; HPV types 5 and 16 did not show any positive signal. In conclusion, the lesion is an example of infection with several HPV types, demonstrated by three different techniques. This suggests the need for careful dermatological or colposcopic follow-up of transplant recipients, in order to prevent possible malignant transformation of anogenital lesions.

Abstract
The complete nucleotide sequence of human papillomavirus type 58 (HPV 58) DNA cloned from an invasive cervical carcinoma was determined. The HPV 58 genome consists of 7824 nucleotides, containing 37.9% of GC residues, and has a similar genome organization of other HPVs. On the nucleotide sequence level, it conserves the signal sequences for regulation of gene expression as with other genital HPVs and exhibits an extensive homology with HPV 33 (77%). Comparative analysis of amino acid sequences reveals that HPV 58 is closely related with HPVs 16, 31, and 33, and is more distantly related with HPVs 6, 11, 18, and 39. HPVs 58, 16, 31, and 33 can be regarded as a group in HPV.
