Penile, Uretral and Seminal Sampling for Diagnosis of Human Papillomavirus Infection in Men.
2006
ABSTRACT Methods that used specimens from three genital sites (penile brushing [PB], urethral brushing [UB], and the retrieval of semen [SE]) from 50 men were examined for human papillomavirus (HPV) DNA detection. The rates of detection by PB, UB, SE, PB and UB, and PB and SE were 88.9%, 50.0%, 33.3%, 100%, and 97.2%, respectively. The use of PB and UB appears to be the most accurate method; as an alternative to UB, the use of SE with PB could be used to improve the rate of HPV DNA detection in men.
A review of virus infections of cataceans and the potential impact of morbilliviruses, poxviruses and papillomaviruses on host population dynamics.
1999
Viruses belonging to 9 families have been detected in cetaceans. We critically review the clinical features, pathology and epidemiology of the diseases they cause. Cetacean morbillivirus (family Paramyxoviridae) induces a serious disease with a high mortality rate and persists in several populations. It may have long-term effects on the dynamics of cetacean populations either as enzootic infection or recurrent epizootics. The latter presumably have the more profound impact due to removal of sexually mature individuals. Members of the family Poxviridae infect several species of odontocetes, resulting in ring and tattoo skin lesions. Although poxviruses apparently do not induce a high mortali…
Distribution and density of CD1a+ and CD83+ dendritic cells in HPV-associated laryngeal papillomas.
2009
Summary Background Respiratory papillomatosis associated with human papilloma virus (HPV) infection is the most common benign laryngeal neoplasm. The age of patients at disease onset, HPV type, number of surgeries are well known prognostic factors of the disease course. The correlation between dendritic cell (DC) density in tumor tissue and clinical prognosis was established. Aim The aim of our study was to estimate the density of DC in laryngeal papillomas associated with HPV types 6/11 infection and to evaluate the relationship between the number of DC and the disease severity. Materials and methods Our study included 40 randomly selected biopsy specimens from patients with HPV-positive l…
Brushing of Oral Mucosa for Diagnosis of HPV Infection in Patients with Potentially Malignant and Malignant Oral Lesions
2006
Introduction: Adequate brushing of oral mucosa is important for accurate human papillomavirus (HPV) detection in potentially malignant (oral leukoplakia [OL], oral lichen planus [OLP]) and malignant (oral squamous cell carcinoma [OSCC]) lesions. Since various factors may limit the adequacy of oral brushing and, consequently, the accuracy of HPV detection, modified sampling procedures should be evaluated for their effect on HPV frequency and/or types detected. Aim: To compare the HPV frequency in samples obtained by brushing the lesion site with the frequency in samples obtained by brushing an apparently normal adjacent site. The correlation between HPV frequency and keratinization of the si…
HPV infection and oral carcinogenesis
2010
To the Editor,High risk human papilloma viruses (HPV) have been found in head and neck squamous cell carcinomas (HNSCC), particularly in oropharyngeal carcinomas (1). Nevertheless, there are some controversial aspects regarding this issue (2) such as whether the HPV infec-tion is a temporary or a persistent oral infection in these patients.Recently, Chuang et al. (3) have associated the presence of HPV-16 DNA in surveillance salivary rinses with a significant risk for recurrence in HNSCC.We hypothesized that the improved prognosis of many patients with HPV-related oropharyngeal carcinoma is due to the temporary nature of the infection, and there-fore in the absence of lesions no HPV genomic…

Vaccination against HPV-Associated Neoplasias
2014
Neoplasias associated with anogenital human papilloma viruses (HPV) are characterised by high patient morbidity and mortality and by appreciable limitations in the patientʼs quality of life. Each year 530,000 women worldwide and 4800 women in Germany develop cervical cancer 1, 2. Biomolecular and epidemiological studies carried out in the past 25 years have demonstrated causal link between persisting infections with HPV 16 and HPV 18 and at least 11 other so-called high-risk HPVs (HR-HPVs) and the development of cervical cancer and its precursor lesions (so-called dysplasias or, respectively, cervical intraepithelial neoplasias – CIN). HPV 16, HPV 18 and other HR-HPVs are also the causes of…
Oral HPV Infection: Current Strategies for Prevention and Therapy
2012
Infection with High Risk (HR) Human Papillomaviruses (HPVs) is the main aetiological agent of Cervical Squamous Cell Carcinoma (CSCC) and also associated in a subgroup of other neoplasms, including Oropharyngeal Squamous cell Carcinoma (OPSCC). HPV infection, in genital as in oral mucosa, can also be subclinical or associated with benign proliferative lesions (common warts, condylomas, papillomas) caused mostly by infection with Low Risk (LR)-HPVs. In the last decades, extensive research has resulted in growing knowledge on HPV biology and specifically viral life cycle, biochemical properties of viral proteins and their interaction with the host proteins leading to potential new targets of …
Prevalence and distribution of human papillomavirus findings in swab specimens from gynaecology clinics of the east coast of Spain.
2010
The objective of this study was to determine the prevalence of human papillomavirus (HPV) among females in the east coast of Spain. A total of 1956 women visiting gynaecology clinics for routine check-ups were included in the study. Swabs were analyzed for HPV DNA by consensus polymerase chain reaction followed by direct sequencing. The overall HPV prevalence was 12.99%. HPV vaccine types 6, 11, 16 and 18 were detected in 6.13% of female participants.
Detection of Human Papillomavirus DNA in Cervical Samples: Analysis of the New PGMY-PCR Compared To the Hybrid Capture II and MY-PCR Assays and a Two…
2004
ABSTRACT The PGMY-PCR for human papillomavirus (HPV) was evaluated, in parallel with nested PCR ( n PCR), in samples with noted Hybrid Capture II (HCII) and MY-PCR results. PGMY-PCR detected HPV DNA in 2.5% of HCII-negative-MY-PCR-negative samples and in 71.7% of HCII-positive-MY-PCR-negative samples; also, it detected the MY-PCR-negative- n PCR-negative types HPV-42, HPV-44, HPV-51, HPV-87, and HPV-89.
