Randomized Controlled Trial Multicenter Study Comparative Study
Efficacy and safety of the fentanyl iontophoretic transdermal system (ITS) and intravenous patient-controlled analgesia (IV PCA) with morphine for pain management following abdominal or pelvic surgery.
The fentanyl HCl iontophoretic transdermal system (ITS) has effectively managed pain following several types of surgery. This study evaluated the efficacy, safety, and ease of care associated with fentanyl ITS and morphine intravenous patient-controlled analgesia (IV PCA) for pain management following abdominal or pelvic surgery. ⋯ Fentanyl ITS and morphine IV PCA were comparable methods of pain control following abdominal or pelvic surgery; however, fentanyl ITS was rated better than morphine IV PCA for ease of care by patients and nurses.

Randomized Controlled Trial Multicenter Study
Use of the Synera patch for local anesthesia before vascular access procedures: a randomized, double-blind, placebo-controlled study.
This randomized, double-blind, placebo-controlled, paired study compared the Synera patch, a drug delivery device comprised of an eutectic mixture of lidocaine (70 mg) and tetracaine (70 mg) whose onset is accelerated by a controlled heating device, with placebo. The objective of the study was to evaluate the efficacy of Synera in inducing local anesthesia before a vascular access procedure. ⋯ A 20-minute application of Synera consistently provided clinically useful anesthesia for vascular access procedures, and appears to be well suited for topical dermal anesthesia due to its reduced time required to produce adequate anesthesia and high subject and investigator acceptance.

Randomized Controlled Trial Multicenter Study
An open-label 52-week clinical extension comparing duloxetine with routine care in patients with diabetic peripheral neuropathic pain.
To assess the safety of duloxetine at a fixed-dose of 60 mg twice daily (BID) for up to 52 weeks, and compare duloxetine with routine care in the management of patients with diabetic peripheral neuropathic pain (DPNP). ⋯ The results of this study provide support for the use of duloxetine in the long-term management of DPNP.

Randomized Controlled Trial Multicenter Study
A double-blind, randomized, placebo-controlled comparison of botulinum toxin type a injection sites and doses in the prevention of episodic migraine.
Several randomized, controlled studies have reported benefits of botulinum toxin type A (BoNTA; Allergan Inc., Irvine, CA, USA) over placebo in the treatment of migraine. Some studies reported significant benefits at dosages as low as 16 U, while other studies reported safety, tolerability, and efficacy at dosages up to 260 U. However, the optimal treatment paradigm and patient population have yet to be defined. ⋯ In this exploratory study of episodic migraine patients, low-dose injections of BoNTA into the frontal, temporal, and/or glabellar muscle regions were not more effective than placebo. BoNTA was safe and well tolerated. Future studies may examine higher BoNTA doses, flexible injection sites, multiple treatments, and disallow concomitant prophylactic medications.

Randomized Controlled Trial Multicenter Study
Duloxetine for the management of diabetic peripheral neuropathic pain: response profile.
The current analysis examines the response profile in patients receiving duloxetine for the management of diabetic peripheral neuropathic pain (DPNP). ⋯ Patients with DPNP receiving duloxetine 60 mg QD or 60 mg BID had significantly higher rates of treatment response, when compared with patients receiving placebo, regardless of the chosen response criterion. Response to duloxetine treatment tended to occur early in therapy.
