Randomized Controlled Trial Comparative StudyComparative sensitivity of stopwatch methodology and conventional pain assessment measures for detecting early response to triptans in migraine: results of a randomized, open-label pilot study.
The standard measure of efficacy used in migraine trials is a 4-point patient-rated headache pain intensity (HPI) scale. However, it has been suggested that using a stopwatch to measure the time to meaningful pain relief can provide a more precise measurement of treatment response. ⋯ The results of this open-label pilot study suggest the convergent validity of 3 pain-assessment methods in migraine, but indicate that the use of a stopwatch may be a more sensitive method for detecting between-group differences.

Patterns of dosage changes with transdermal buprenorphine and transdermal fentanyl for the treatment of noncancer and cancer pain: a retrospective data analysis in Germany.
Previous studies have suggested that buprenorphine may have a low association with tolerance development compared with other strong opioids. In a previous study by our group, mean cohort and intraindividual dosage increases over an entire course of treatment and on a per-day basis were significantly lower with transdermal (TD) buprenorphine than with TD fentanyl. However, no information concerning the relationship between qualitative and quantitative dose changes is available. ⋯ In this retrospective data analysis, compared with TD buprenorphine, the increase in mean daily dosage was significantly greater in patients treated with TD fentanyl. Also, compared with TD buprenorphine, alternating dosage changes were seen in a significantly greater proportion of patients receiving TD fentanyl. On the other hand, a significantly greater proportion of patients treated with TD buprenorphine had stable dosages over their entire treatment periods.

Randomized Controlled Trial Multicenter Study Comparative StudyA post hoc subgroup analysis of meropenem versus imipenem/cilastatin in a multicenter, double-blind, randomized study of complicated skin and skin-structure infections in patients with diabetes mellitus.
In a multicenter, international, double-blind, randomized clinical trial involving hospitalized patients with complicated skin and skin-structure infections (cSSSIs), meropenem and imipenem/cilastatin (both administered 500 mg intravenously every 8 hours) were not significantly different in their efficacy and safety profiles. ⋯ This subgroup analysis found that 500 mg every 8 hours intravenously of meropenem or imipenem/cilastatin appeared efficacious and well tolerated for the treatment of cSSSIs among these patients with and without DM.

Randomized Controlled Trial Multicenter Study Comparative StudyLevofloxacin 750 mg QD for five days versus amoxicillin/clavulanate 875 mg/125 mg BID for ten days for treatment of acute bacterial exacerbation of chronic bronchitis: a post hoc analysis of data from severely ill patients.
This post hoc analysis of data from a previous randomized, blinded, multicenter, parallel, noninferiority study assessed the bacterial etiology, symptom resolution, and tolerability of severe acute bacterial exacerbation of chronic bronchitis (ABECB) patients treated with either levofloxacin 750 mg QD for 5 days or amoxicillin/clavulanate 875 mg/125 mg BID for 10 days. Severe ABECB was defined as ABECB and forced expiratory volume in 1 second (FEV(1)) <50% of the predicted value, or (FEV(1)) of 50% to 65% of the predicted value plus comorbidities, or > or =4 exacerbations per year. A total of 369 patients were included in the intent-to-treat (ITT) population (187 treated with levofloxacin and 182 treated with amoxicillin/clavulanate), and 175 patients were microbiologically assessable (MA) (86 treated with levofloxacin and 89 treated with amoxicillin/clavulanate). ⋯ A total of 341 pathogens were isolated, of which 143 (41.9%) were traditional ABECB flora, 181 (53.1%) were other gram-negative organisms, and 17 (5.0%) were gram-positive organisms. Overall susceptibility of the pathogens was 97.1% for levofloxacin and 90.6% for amoxicillin/clavulanate (P < 0.001). The prevalence of treatment-emergent adverse events was 42.1 % in patients who received levofloxacin and 48.6 % in those who received amoxicillin/clavulanate (95% CI,-4.0 to 17.0).

Randomized Controlled TrialInfluence of age on flurbiprofen axetil requirements for preventing pain on injection of propofol in Japanese adult surgical patients: a prospective, randomized, double-blind, vehicle-controlled, parallel-group, dose-ranging study.
Pain on injection is a recognized adverse event (AE) of propofol administration for the induction of general anesthesia. Preceded by venous occlusion, flurbiprofen axetil, a prodrug of the NSAID flurbiprofen, has been associated with a reduction in pain induced by propofol injection. A review of the literature determined that no published data were available on the influence of age on the requirements for flurbiprofen axetil dose. ⋯ In this small clinical trial in Japanese surgical patients undergoing general anesthesia, flurbiprofen axetil requirements for the reduction of pain during injection of propofol were found to be 50 mg in young adults (age 20-40 years) and 25 or 50 mg in older adults (age 60-80 years), regardless of weight, preceded by venous occlusion for 2 minutes.
