Variant GII.4 noroviruses in Italian children

Objectives: Among human noroviruses (NoVs), a few genogroup II strains of genotype 4 (GII.4) are dominant worldwide. GII.4 NoVs evolve rapidly and in 2006 two new epidemic variants have been identified. To investigate the circulation of GII.4 NoV variants in Italy a sequence analysis was performed on NoV strains obtained from children hospitalized for sporadic viral gastroenteritis in Palermo. Methods: A total of 465 faecal specimens were collected from children (< 5 years) hospitalized from January 2005 to December 2006. The presence of NoVs was detected by RT-PCR using primers JV12/JV13, targeting the region A of the RNA-dependent RNA-polymerase (RdRp) gene. NoV strains were genotyped by …

Giant condyloma acuminatum quickly growing: case report

Background. Giant Condyloma Acuminatum (GCA) is a rare, slow growing, large cauliflower tumor of the penile foreskin and peria- nal region with benign histologic appearance but high propensity for lo- cal invasion and recurrences. GCA is associated with Human Papillo- ma Virus (HPV) types 6 and 11 and it also has considerable risk of neo- plastic transformation into fully invasive squamous cell carcinoma in- to about 5 years. Objective. Because of the rarity of perianal GCA, to date there is no general agreement on the best method for treatment. We wanted to know if surgical approach only was a good method to treat our case. Case report. A 28 years old man, HIV-negative, with a 4 years hi- …
