Continuous increase in HIV-1 incidence after the year 2000 among men who have sex with men in Rome: insights from a 25-year retrospective cohort study.

To assess trends in HIV-1 incidence and risk factors for seroconversion among men who have sex with men (MSM) resident in Rome, Italy, a retrospective longitudinal cohort study was conducted over 25 years. Incidence rates and trends were modelled using Poisson regression and risk factors were assessed by multivariate Cox models. Of 1,862 HIV-1-negative individuals, 347 seroconverted during follow-up.

Comparative evaluation of different DNA extraction methods for HPV genotyping by linear array and INNO-LiPA.

In order to investigate the influence of DNA extraction on two PCR-based HPV genotyping tests (Linear Array, Roche and INNO-LiPA Extra, Innogenetics), three different procedures were used to purify DNA from 28 cervico-vaginal samples tested previously by the Hybrid Capture 2: the AmpliLute Liquid Media Extraction kit (Roche), the QIAamp DNA Blood mini kit (QIAGEN), and the NucliSENS EasyMAG automated platform (bioMérieux). All HC2-positive samples were found positive by both assays, independently of the extract used. Type-specific concordance (i.

Increased HIV incidence among men who have sex with men in Rome.

Among 976 men who have sex with men (MSM) who had undergone repeat HIV testing between 1984 and 2003 at a sexually transmitted infection clinic in Rome, Italy, we observed a dramatic increase in HIV incidence in 2002 and 2003, with the cumulative incidence for 2000-2003 being twice as high as that for 1984-1995, and significantly higher than that for 1996-1999. This trend suggests the need for interventions aimed at encouraging behavioural changes among MSM.

Prevalence of human papilloma virus type 5 DNA in lesional and non-lesional skin scales of Italian plaque-type psoriatic patients: association with disease severity.

Human papilloma virus type 5 (HPV-5) has been associated closely with psoriatic skin in Polish patients, while findings from other countries have indicated a more limited prevalence. The results of the present study, in which a type-specific nested PCR was used, indicated that scales of plaque-type psoriatic skin from 54 Italian patients had a high prevalence (74.1%) of HPV-5 DNA in lesional areas, and a reduced prevalence (33.
