Atypical Gianotti-Crosti syndrome in two HIV and hepatitis B co-infected adults.

We describe an atypical Gianotti-Crosti syndrome in two 43-year-old, unrelated adult male patients with coexistent hepatitis B and HIV infection. Both cases shared many of the hallmarks of childhood Gianotti-Crosti syndrome. We believe that this is the first report in the literature of a Gianotti-Crosti syndrome-like paraviral eruption in HIV and hepatitis B positive adults.

Surgical masks: operative field contamination following visor-to-visor contact.

Background: Clashing of surgical visor masks frequently occurs when two surgeons bend over an operative field simultaneously; however, it is unknown whether this results in contamination. The purpose of the present study was to determine the potential for operative field contamination following surgical visor-mask clashes. The nature of bacterial contamination was also assessed.
