Ten Years of Participatory Cinema as a Form of Political Solidarity with Refugees in Italy. From ZaLab and Archivio Memorie Migranti to 4CaniperStrada

This paper introduces the context of European mobilizations for and against refugees and how participatory cinema has become a way of expressing political solidarity with refugees in Italy. We present and discuss ten years of the artistic work of ZaLab and Archivio Memorie Migranti and focus on two film projects of 4CaniperStrada. Central to the production of participatory cinema in Italy is challenging the mainstream narrative of migration through the proactive involvement of asylum seekers, with their political subjectivity, by using a self-narrative metho

Prevalence and type distribution of human papillomavirus infection in women from North Sardinia, Italy

<p>Abstract</p> <p>Background</p> <p>Human papillomavirus (HPV) has been associated with several disorders of the genital tract, skin and oropharynx. The aims of our study were to evaluate the prevalence of HPV infection in women between 15 and 54 years of age in North Sardinia, Italy, to identify the prevalence of High Risk - Human papillomaviruses (HR-HPV) genotypes and to establish a correlation between molecular and cytological results.</p> <p>Methods</p> <p>From 2007 to 2009 we consecutively enrolled women aged 15-54 years admitted to public and private outpatient settings. All the participants filled in a questionnaire about the socio-cultural state, sexual activity and awareness about HPV. 323 cervical specimens were tested for HPV-DNA and HPV genotypes with INNO-LiPA HPV Genotyping CE Amp kit. Samples showing positivity to some HPV genotypes were re-tested using "in house" quantitative Real-Time PCR assays.</p> <p>Results</p> <p>Overall HPV-DNA positivity was detected in 35.9% of the women. The prevalence of HR-HPV infection among HPV positive samples was 93.1% with a specific prevalence of HPV 16, 51, 31, 53 and 18 of 54.3%, 37.9%, 10.3%, 6.9% and 5.2%, respectively. Co-infection with any HPV, HR-HPV, LR-HPV and HR/LR-HPV type was 18.3%, 14.9%, 0.9% and 2.5%, respectively; HPV 16/51 co-infection was detected in 64.6% of the HR-HPV co-infection group. The most frequent HPV-genotypes detected were 16 (32.5%) and 51 (22.7%). Among the 57 patients harboring mono-infection the most prevalent HPV genotypes were 16 (38.6%) and 31(10.5%). A multivariate analysis identified a statistical significant association between HPV infection and age and between HPV infection and previous sexual transmitted diseases. A statistically significant association between cytological cervical lesions and generic HPV exposure was identified.</p> <p>Conclusions</p> <p>To our knowledge, this is the first survey evaluating the prevalence of HPV infection in Northern Sardinia and drawing attention to the unusual high proportion of genotype HPV 51. Given the recent implementation of a widespread immunization program with vaccines not containing HPV 51, it has been relevant to prove the high prevalence of this HPV genotype from the start of the vaccination campaign, in order to avoid in the future attributing to the vaccination program a possible selection effect (HPV replacement).</p

Molecular methods for the detection of human papilloma virus infection: new insights into their role in diagnostics and epidemiological surveillance

Human papillomaviruses (HPVs) comprise more than 180 genotypes. HPV infection is mainly diagnosed by molecular methods. The aim of our study was to review the main molecular methods used to diagnose HPV infection, underscoring their characteristics. Several methods have been developed for molecular diagnosis of Papilloma infection, such as those based on PCR technique. Another commercial non-PCR based diagnostic method is Hybrid Capture test; it is the only commercially available HPV DNA detection test approved by the FDA. Several Authors have suggested that viral load and E6/E7 transcripts could be used as surrogate markers of persistent HPV infection, being more specific predictors of progressive disease than the simple presence of HPV DNA. Validating clinical sensitivity and specificity of each technique and improving the interpretation of the results are essential; consequently, there is a clear need for well characterized international quality control panels to compare the various diagnostic methods. HPV DNA testing could be useful both as a primary screening test, alone or in combination with a Pap smear, for the early detection of cervical cancer precursors, and as triage test to select women with minor cytological abnormalities who will need further follow-up and to predict possible treatment failure in women with diagnosed high-grade intraepithelial lesions who have undergone excisional therapy. In the next future surveillance for HPV infections, based on these molecular methods, could represent an important step for the development of primary and secondary prophylactic interventions, such as new vaccines targeted to genotypes who might replace those previously prevalent

High HPV-51 prevalence in invasive cervical cancers: results of a pre-immunization survey in North Sardinia, Italy.

BACKGROUND: Human Papilloma virus (HPV) is recognized as the etiological agent of benign and malignant ano-genital lesions. The most prevalent genotypes associated with cervical carcinoma are HPV-16 and -18 worldwide. However, recent studies have emphasized the role of other genotypes, such as HPV-51, in the pathogenesis of cervical dysplasia. The aim of the study was to estimate the burden of HPV-51 infection in invasive cervical malignant lesions in Northern Sardinia, Italy. METHODS/PRINCIPAL FINDINGS: An observational, retrospective, prevalence, mono-center study was carried out to evaluate the presence of HPV genotypes in tissues biopsies of cervical lesions (CIN-1, CIN-2, CIN-3 and invasive carcinoma) gathered from 1996 to 2009. Biological samples were collected from women admitted consecutively to a tertiary university hospital situated in Sassari, Italy. Molecular methods were used to identify 28 oncogenic HPV types. A total of 155 formalin-fixed and paraffin-embedded cervical tissue samples were analyzed. Approximately half of the cervical lesions were classified as invasive carcinoma. HPV-DNA was detected in 71% of the samples, with a higher frequency (100%) in those categorized as invasive neoplasia. Mono- or co-infections were demonstrated in 45.8% and 25.8% of the cervical samples, respectively. Overall, the most prevalent HPV types were -16 (49%) and -51 (19.4%), with an increased frequency of detection associated with the severity of the cervical lesions. CONCLUSIONS/SIGNIFICANCE: This survey highlights for the first time the relevant role of HPV-51 infection in the pathogenesis of invasive cervical cancer prior to the introduction of a vaccination program. Although a selection bias could have influenced the results, other recent studies have described the impact of HPV-51. This remarkable epidemiological element should be carefully evaluated, particularly in the view of opting for preventive vaccines, whose cross-protection patterns determine their efficacy in protecting against infection from HPV types that are not included in the vaccine itself
