Low rate of oral Human Papillomavirus (HPV) infection in women with genital HPV infection
Brushing of Oral Mucosa for Diagnosis of HPV Infection in Patients with Potentially Malignant and Malignant Oral Lesions
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 in semen: evaluation of the link among infection, sperm parameters and viral genome integration
Human papillomaviruses (HPVs) are agents of the most common sexually transmitted diseases. Both in men and in women, HPVs cause a variety of clinical symptoms ranging from warts to cancer. It has been shown that infection with oncogenic HPV is the major cause of development of cervical cancer in women and less frequently of penile cancers in men. HPV infects epithelial cells and can bind other cell types. Its presence in semen is widely known, but the effects on fertility and reproductive function are still controversial. Partners of women with high-grade squamous intraepithelial lesions were enrolled. From each subject seminal parameters were evaluated. HPV was detected and genotyped both …
Oral human papillomavirus infection in women with cervical HPV infection: new data from an Italian cohort and a metanalysis of the literature.
Summary A key issue in oral HPV infection is whether it can be associated with a genital HPV infection, or whether it can be considered as an independent event. This analysis evaluated the frequency and type-concordance of oral HPV infection in women with cervical HPV infection by means of: (i) a cross-sectional study on a sample (n = 98) of Italian women; and (ii) a literature-based metanalysis, including the experimental study the subject of this Paper and nine other published studies (n = 1017), which also examined the influence of oral sampling procedure (oral brushing vs oral rinse) and HIV status on oral HPV detection. The prevalence of oral HPV infection in the Italian study was 14.3…

HPV Infection in partners of women with HPV positive cervical cytology: diagnosis by sampling different genital sites.
Penile, Uretral and Seminal Sampling for Diagnosis of Human Papillomavirus Infection in Men.
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.
Molecular analyses on HPV infections in semen
Introduction: Human Papillomaviruses (HPVs) are non-enveloped double stranded DNA viruses classified in different genera and several different genotypes. Depending on the genotypes, HPV infections can be asymptomatic or can cause from warts to malignant tumours. Some genotypes, such as HPV18 and HPV16, are considered high risk (HR) HPVs and they are the major cause of cervical cancer. HPV is highly tissue-tropic and infects epithelial cells, but it can also binds other cell types. It is known that HPV can be found in semen but its effects on spermatozoa and male reproductive system are not completely clarified. Materials and Methods: In order to study the HPV infection in semen, we develope…
LOW RATE OF ORAL HUMAN PAPILOMAVIRUS (HPV) INFECTION IN WOMEN WITH GENITAL HPV INFECTION.
Presence of Rickettsia conorii subsp. israelensis , the Causative Agent of Israeli Spotted Fever, in Sicily, Italy, Ascertained in a Retrospective Study
ABSTRACT A retrospective analysis by molecular-sequence-based techniques was performed to correctly identify the etiological agent of 24 Mediterranean spotted fever cases occurring in Western Sicily, Italy, from 1987 to 2001. Restriction analysis of a 632-bp PCR-amplified portion of the ompA gene allowed presumptive identification of five clinical isolates as belonging to Rickettsia conorii subsp. israelensis , the etiological agent of Israeli spotted fever (ISF). The remaining 19 rickettsial isolates were Rickettsia conorii subsp. conorii , the only pathogenic rickettsia of the spotted fever group reported in Italy until the present. Sequence analysis of the ompA gene confirmed the identif…
HPV DETECTION BY ORAL BRUSHING:A MODIFIED SAMPLING PROCEDURE FOR POTENTIALLY MALIGNANT LESIONS AND ORAL CANCER
CONCORDANCE AND DISTRIBUTION OF HPV GENOTYPES IN HPV INFECTED SEXUAL COUPLES
Introductions: The characteristics of HPV infection in women have been extensively investigates, however, only a few studies have analyzed the characteristics of HPV infection in men and in sexual couples. Materials and methods: 195 sexual couples positive for HPV-DNA were examined, at the Virology laboratory of the Department of Sciences for Health Promotion and Mother and Child Care (Policlinico, University of Palermo, Italy). HPV-DNA detection was performed by the INNOLiPA HPV Genotyping Extra II Test (Fujirebio) and nested PCR/sequencing method. All women (range: 20-60, mean age: 31.5 ys) had performed a pap smear and knew the cytological diagnosis: 73 (37.4%) negative at Pap smear, 21 …

HPV genotype prevalence in cytologically abnormal cervical samples from women living in south Italy
Human papillomavirus (HPV) infection is the commonest sexually transmitted infection, and high-risk HPV types are associated with cervical carcinogenesis. This study investigated: the HPV type-specific prevalence in 970 women with an abnormal cytological diagnosis; and the association of HPV infection and cervical disease in a subset of 626 women with a histological diagnosis. HPV-DNA was researched by nested PCR/sequencing and the INNOLiPA HPV Genotyping assay. The data were analysed by the chi-square test (p ? 0.05 significant). Overall, the HPV prevalence was 37.7%; high-risk genotypes were found in 88.5% of women and multiple-type infections in 30.9% of the HPV-positive women. The commo…

HPV group- and type-specific concordance in HPV infected sexual couples.
The concordance of human papillomavirus (HPV) groups and types was evaluated in 45 sexual couples with both partners HPV infected, by analyzing cervical samples from women and three genital sites (penile brushing, urethral brushing, and semen) from men. When grouping HPV types, no significant HPV group sharing was found between partners, either considering samples from any male site (concordance: 55.5%; P = 0.11) or from each site (concordance by penile brushing, 37.8%; urethral brushing, 24.5%; semen, 22.3%; P > 0.05). Examining individual HPV types, using samples from any male site, concordance was found in 29 (64.4%; P = 0.036) couples; significant concordance was evident for 16 HPV geno…

The EBV-DNA Can be Used as a Diagnostic and Follow-up Parameter of the Rhinopharyngeal Tumors in the Non-Endemic Population of the Western Sicily
To evaluate whether EBV-DNA can be used as a diagnostic and follow-up parameter for nasopharyngeal tumors in a non-endemic population. The study was carried out in a university hospital. A retrospective study was conducted on 40 paraffin samples of histological preparations. EB-DNA was detected by real-time PCR technique. A prospective study was also conducted on a group of 30 patients who underwent nasopharyngeal biopsy for suspected nasopharyngeal carcinoma (NPC) by comparing EBV-DNA concentrations between the histological specimen and the serum. Quantification of genomic copies of EBV-DNA in serum and detection of anti-EBV antibodies was performed. In both groups the presence of high vir…
Human Papillomavirus infection and genotypes among migrant women in Palermo, Italy: association with cervical lesions and socio-demographic features
Prevalence of cervical human papillomavirus infection and types among women immigrated to Sicily, Italy.
We determined the prevalence of human papillomavirus (HPV) cervical infection and HPV genotypes among 115 women immigrating to Sicily (Italy), with regard to abnormal cytology and socio-behavioral characteristics in a cross-sectional, observational study. Information was collected with the help of cultural mediators/translators. HPV-DNA was assayed by the INNOLiPA HPV assay and a nested PCR/sequencing method. Sixty (52.2%) women came from sub-Saharan Africa and 55 (47.8%) from Eastern Europe. HPV infection was found in 55 (47.8%) women. The most frequent types were the oncogenic types HPV-16 (7.8%), HPV-18 and 51 (6.0% each), HPV-52 (5.2%), 31, 53, and 68 (4.3% each). Twenty-seven (23.5%) w…
