Randomized Controlled Trial Multicenter Study
5% lidocaine medicated plaster versus pregabalin in post-herpetic neuralgia and diabetic polyneuropathy: an open-label, non-inferiority two-stage RCT study.
To compare efficacy and safety of 5% lidocaine medicated plaster with pregabalin in patients with post-herpetic neuralgia (PHN) or painful diabetic polyneuropathy (DPN). ⋯ 5% lidocaine medicated plaster showed better efficacy compared with pregabalin in patients with PHN. Within DPN, efficacy was comparable for both treatments. 5% lidocaine medicated plaster showed a favourable efficacy/safety profile with greater improvements in patient satisfaction and QoL compared with pregabalin for both indications, supporting its first line position in the treatment of localized neuropathic pain.

Randomized Controlled Trial Multicenter Study
Efficacy and safety of combination therapy with 5% lidocaine medicated plaster and pregabalin in post-herpetic neuralgia and diabetic polyneuropathy.
Neuropathic pain is often difficult to treat due to a complex pathophysiology. This study evaluated the efficacy, tolerability and safety of combination therapy with 5% lidocaine medicated plaster and pregabalin for neuropathic pain in patients with post-herpetic neuralgia (PHN) or painful diabetic polyneuropathy (DPN). ⋯ In patients with PHN and painful DPN failing to respond to monotherapy, combination therapy with 5% lidocaine medicated plaster and pregabalin provides additional clinically relevant pain relief and is safe and well-tolerated.

Randomized Controlled Trial Multicenter Study
Three-month, randomized, parallel-group comparison of brimonidine-timolol versus dorzolamide-timolol fixed-combination therapy.
Fixed combinations of 0.2% brimonidine-0.5% timolol and 2% dorzolamide-0.5% timolol are used to lower intraocular pressure (IOP). The objective of this study was to evaluate the IOP-lowering efficacy and ocular tolerability of brimonidine-timolol compared with dorzolamide-timolol when used as monotherapy or as adjunctive therapy to a prostaglandin analog (PGA) in patients with glaucoma or ocular hypertension. ⋯ Fixed-combination brimonidine-timolol provided the same or greater IOP lowering compared with fixed-combination dorzolamide-timolol. Both fixed-combination medications were safe and well-tolerated. Brimonidine-timolol received higher ratings of ocular comfort than dorzolamide-timolol. The duration of the studies was 3 months, and additional studies will be needed to compare the efficacy and tolerability of brimonidine-timolol and dorzolamide-timolol during long-term treatment.

Multicenter Study
Relative strength of relationships of nasal congestion and ocular symptoms with sleep, mood and productivity.
Nasal congestion associated with allergic rhinitis has been shown to be the most bothersome symptom. Ocular symptoms may be troublesome to patients as well. ⋯ Although nasal congestion is generally more strongly related to the patient-reported outcomes, ocular symptoms have a significant negative effect on patients' lives. Study limitations include: (1) only baseline data were used because of greater severity and variability of symptoms scores; we are unable to establish causal relationships or discuss change, only correlation/covariation; (2) recruitment took place from September through November, thus different patients might have been recruited if sampling took place during the spring; (3) patients were screened for nasal congestion not for ocular symptoms, though there was high co-occurrence of each. These limitations aside, congestion and ocular symptoms are troublesome to patients and typically co-occur. Evaluating and treating these symptoms are key to managing allergic rhinitis and improving patient-reported outcomes.

Randomized Controlled Trial Multicenter Study Comparative Study
Comparison of postoperative pain outcomes after vertical or Pfannenstiel incision for major gynecologic surgery.
The Pfannenstiel incision is commonly used for gynecologic surgery. It is not known if this incision is associated with less postoperative pain compared to a vertical midline incision. Therefore, as part of a study to evaluate the postoperative analgesic effects and dose response of intravenous adenosine in patients undergoing open abdominal gynecologic surgery, this manuscript compares postoperative pain and analgesic consumption in patients who had a midline vertical incision or a Pfannenstiel incision. ⋯ There was no significant difference in postoperative pain and opioid consumption in patients undergoing major abdominal gynecologic surgery performed with either a midline or Pfannenstiel incision. However, it is important to note that since this a secondary analysis of data from a primary study investigating the dose response of IV adenosine, the patients were not prospectively randomized into the two incision types.
