Beards in the operating room are controversial because of their potential to retain and transmit pathogenic organisms. Many bearded orthopedic surgeons choose to wear nonsterile hoods in addition to surgical masks to decrease contamination of the operative field. The goal of this study was to determine whether nonsterile surgical hoods reduce the risk of bacterial shedding posed by beards. Bearded (n=10) and clean-shaven (n=10) subjects completed 3 sets of standardized facial motions, each lasting 90 seconds and performed over blood agar plates, while unmasked, masked, and masked and hooded. The plates were cultured for 48 hours under aerobic and anaerobic conditions. Colony-forming units (CFUs) were quantified, expanded, and identified. Overall, the addition of surgical hoods did not decrease the total number of anaerobic and aerobic CFUs isolated per subject, with a mean of 1.1 CFUs while hooded compared with 1.4 CFUs with the mask alone (P=.5). Unmasked subjects shed a mean of 6.5 CFUs, which was significantly higher than the number of CFUs shed while masked (P=.02) or hooded (P=.01). The bearded group did not shed more than the clean-shaven group while unmasked (9.5 vs 3.3 CFUs, P=.1), masked (1.6 vs 1.2 CFUs, P=.9), or hooded (0.9 vs 1.3 CFUs, P=.6). Bearded surgeons did not appear to have an increased likelihood of bacterial shedding compared with their nonbearded counter parts while wearing surgical masks, and the addition of nonsterile surgical hoods did not decrease the amount of bacterial shedding observed.

Infectious complications are a major cause of morbidity and mortality in transplant recipients. We describe a case of fatal disseminated aspergillosis immediately following autologous peripheral stem cell reconstitution in a patient who had undergone orthotopic heart transplantation for systemic amyloidosis. The case described suggests that the infectious risks in patients undergoing these sequential procedures may be distinct from those occurring in patients undergoing either procedure independently. Potential prophylactic and therapeutic interventions are discussed. Since this experimental and evolving approach for the management of systemic amyloidosis is potentially applicable to a limited number of patients, multicenter collaboration may be needed to further define the infectious risks in this unique subset of transplant recipients.
