Severe Ocular Bacterial Infections: A Retrospective Study Over 13 Years.

PURPOSE: To report data of samples collected from January 2000 to August 2013, in the Department of Diagnosis and Laboratory Analysis, Ophthalmic Hospital, Turin, Italy, from different types of ocular infections and their antibiotic susceptibility. METHODS: Collected samples were cultured using both liquid and solid media. Then bacterial isolates were tested for antibiotic susceptibility using the Kirby-Bauer diffusion method and the National Committee for Clinical Laboratory Standards (NCCLS) serum standards. RESULTS: Staphylococcus aureus is the most common bacteria isolated in ocular samples. CONCLUSIONS: In vitro susceptibility tests showed that levofloxacin and moxifloxacin (introduced only in 2010) had the highest efficacy against bacterial isolates.

The extrahepatic manifestations of hepatitis B virus infection include reactive arthritis, vasculitis (panarteritis nodosa) and primary glomerulonephritis (membranous nephropathy, membranoproliferative glomerulonephritis and, less frequently, IgA nephropathy, focal and segmental glomerulosclerosis, minimal change disease, and extracapillary glomerulonephritis). No specific histomorphological patterns have been reported in association with HDV infection. Cryoglobulinemic glomerulonephritis is the only pattern of glomerular involvement unequivocally related to HCV infection. The treatment of HBV-related glomerulopathies is essentially antiviral. Corticosteroids have been proven to be ineffective (except in panarteritis nodosa), while immunosuppressants can lead to exacerbation of HBV infection. The treatment of HCV-related nephritis, especially cryoglobulinemic glomerulonephritis, encompasses various options including both conventional and novel immunomodulatory agents, possibly combined with antiviral therapy.
