Bortezomib, an antineoplastic agent that is the standard of care in patients with multiple myeloma, has been reported to be associated with Sweet's syndrome. We describe a 69-year-old man who developed Sweet's syndrome during his initial course (after cycle 4) of bortezomib for treatment of multiple myeloma; he again experienced Sweet's syndrome 3.5?years later when rechallenged with bortezomib (after cycle 5) for treatment of relapsed multiple myeloma. The patient's signs, symptoms, and biopsy results were identical during both presentations of Sweet's syndrome. In both instances, the syndrome spontaneously resolved without incident and without supportive treatment with corticosteroids or antihistamines. To our knowledge, this is the first case report of a patient who developed Sweet's syndrome during an initial course of treatment with bortezomib and after rechallenge with bortezomib for relapsed disease. As proteasome inhibitors continue to be a mainstay selleck products of therapy for SCH772984 both treatment and salvage therapy for multiple myeloma, this case demonstrates that rechallenge with bortezomib is an option for patients who develop Sweet's syndrome. ""Study Objective. To determine if increased expression of efflux pumps, mutations in the genes encoding regulatory proteins for efflux pumps, or the combination is associated with multidrug-resistant (MDR) Pseudomonas aeruginosa isolates. Design. Microbiologic evaluation of prospectively collected Pseudomonas aeruginosa isolates. Setting. University teaching hospital. Isolates. One hundred eight unique P. aeruginosa isolates��50 non-MDR and 58 MDR isolates��obtained from pulmonary or blood sources from patients admitted to the intensive care unit between January 1, 1999, and December 31, 2004. Measurements and Main Results. Isolates were considered MDR if they were resistant to at least three of the following four drugs: ciprofloxacin, tobramycin, ceftazidime, or imipenem. Possible mutations in efflux Ritonavir regulatory genes mexR, nfxB, and mexZ were analyzed by using polymerase chain reaction amplification and DNA sequencing. Determination of the expression of outer membrane proteins OprM and OprJ was performed by using sodium dodecyl sulfate-polyacrylamide gel electrophoresis immunoblotting. Differences in regulatory gene mutations and outer membrane protein expression were compared between non-MDR and MDR isolates. Among the 108 P. aeruginosa isolates, the MDR isolates were more likely to overexpress OprM compared with non-MDR isolates (64% vs 2%, p
