New Research Published on Antibiotic resistance determinants in Acinetobacter spp

March 31, 2010

We explored the association of antibiotic-resistant phenotypes and genotypes in Acinetobacter spp with clinical outcomes and characteristics in 75 patients from a major military treatment facility. Amikacin resistance was associated with nosocomial acquisition of A baumannii, and carbapenem resistance and bla(OXA-23) were associated with the need for mechanical ventilation. The presence of bla(OXA-23) also correlated with longer hospital and ICU stay. Associations between bla(OXA-23) and complexity, duration, and changes made to antibiotic regimens also existed.

Read why Cushing’s syndrome: Why is diagnosis so difficult?

March 31, 2010

Practicing and perfecting the art of medicine demands recognition that uncertainty permeates all clinical decisions. When delivering clinical care, clinicians face a multiplicity of potential diagnoses, limitations in diagnostic capacity, and “sub-clinical” disease identified by tests rather than by clinical manifestations. In addition, clinicians must recognize the rapid changes in scientific knowledge needed to guide decisions. Cushing’s syndrome is one of several disorders in which there may be considerable difficulty and delay in diagnosis. This article describes a current model of clinical reasoning, some of its challenges, and the application of the principles of clinical epidemiology to meet some of those challenges.
