1.  Community acquired fungemia caused by Candida pulcherrima: diagnostic contribution of MALDI-TOF mass spectrometry 
Background
Community-onset candidemia constitute a distinct clinical entity the incidence of which is increasing. Contribution of non-albicans Candida species is rising.
Case presentation
We describe here the first reported case of community acquired fungemia due to Candida pulcherrima. Identification to the species level was performed by MALDI-TOF mass spectrometry. Treatment with fluconazole was successful.
Conclusion
This case confirms the pathogenic role of C. pulcherrima and the contribution of MALDI-TOF mass spectrometry for identification of rare Candida species.

2.  Bilateral One-Stage Revision of Infected Total Hip Arthroplasties: Report of Two Cases and Management of Antibiotic Therapy 
Case Reports in Orthopedics  2016;2016:3621749.
Recommendations for the management of chronic and bilateral total hip arthroplasty (THA) infection are lacking. However, this type of infection involves medical problems concerning the management of the antibiotic therapy. We report two cases of such infections operated as one-stage revision. For each case, both hips were infected with the same bacteria (Staphylococcus caprae for one patient and methicillin-sensitive Staphylococcus aureus for the other). The probabilistic antibiotic treatment started during the first side (after harvesting intraoperative samples) did not prevent the culture of the bacteriologic harvested during the intervention of the second side. Cultures were positive for the same bacteria for both sides in the two cases presented herein. After results of intraoperative cultures, patients received culture-guided antibiotic therapy for three months and were considered cured at the end of a two-year follow-up. Our results suggest one-stage bilateral change of infected THA is a viable option and that early intraoperative antibiotic, started during the first-side exchange, does not jeopardize microbiological documentation of the second side. This work brings indirect arguments, in favor of the use of prophylactic antibiotics during revision of infected THA.

3.  First Case of Osteomyelitis Caused by “Staphylococcus pettenkoferi”▿  
Journal of Clinical Microbiology  2007;45(3):1069-1071.
“Staphylococcus pettenkoferi” (proposed name) was identified as an unusual agent of osteomyelitis in a diabetic foot infection. The phenotypical tests used failed to give a good identification. Molecular 16S rRNA gene and rpoB sequencing allowed us to correctly identify this new species of coagulase-negative staphylococcus responsible for this chronic infection.
