To evaluate the effectiveness of gabapentin in adults with phantom limb pain. ⋯ Given the results of these trials, oral gabapentin in patients aged 18 years or older may decrease phantom limb pain. A strong recommendation for the effectiveness of gabapentin in phantom limb pain cannot be ascertained until more methodologically sound studies are executed in this population.

Guidelines recommend that agents other than vancomycin be considered for some types of infection due to methicillin-resistant Staphylococcus aureus (MRSA) when the minimum inhibitory concentration (MIC) to vancomycin is 2 μg/mL or more. Alternative therapeutic options include daptomycin and linezolid, 2 relatively new and expensive drugs, and trimethoprim/sulfamethoxazole (TMP/SMX), an old and inexpensive agent. ⋯ TMP/SMX monotherapy compared favorably to linezolid and daptomycin in terms of treatment efficacy and mortality. Use of TMP/SMX instead of linezolid or daptomycin could potentially significantly reduce antibiotic costs. TMP/SMX should be considered for the treatment of MRSA infection with MIC of 2 μg/mL to vancomycin.

Role of new drugs for management of atrial fibrillation.
To evaluate the role of newer agents in the management of atrial fibrillation (AF). ⋯ Use of dronedarone should be limited to patients with paroxysmal or persistent AF and should not be used in patients with heart failure or with permanent AF. Newer antithrombotic agents appear to be promising alternatives for the prevention of stroke in patients with AF; however, more data are needed to understand their role.

To investigate the nature of the interaction between selective serotonin reuptake inhibitors (SSRIs) and tramadol to mitigate or avoid serotonin syndrome. ⋯ Coadministration of tramadol and SSRIs has caused serotonin syndrome. An attempt should be made to identify individuals who are poor metabolizers of CYP2D6 and avoid this combination in those patients. When SSRIs and tramadol must be used in combination, it is critical that patients be aware of the signs and symptoms of serotonin syndrome, should they occur.

Comparative Study
Vitamin K dosing to reverse warfarin based on INR, route of administration, and home warfarin dose in the acute/critical care setting.
Vitamin K is commonly used for reversal of anticoagulation of warfarin. However, the optimal dose and route of vitamin K that does not increase the duration of bridging therapy is unknown. ⋯ Vitamin K dose, route, and initial INR influence subsequent INR values. INR reduction is similar for intravenous vitamin K doses of 2 mg or greater. Preadministration of FFP does not alter INR values at 48 hours or more after vitamin K administration.
