Randomized Controlled Trial Comparative Study
High- Versus Low-Density Fractional Laser in the Treatment of Hypertrophic Postburn Scars: A Randomized Clinical Trial.
Fractional CO2 laser has been shown effective in improving pigmentation, pruritus, and tightness of hypertrophic burn scars. However, there is no consensus on the optimal treatment parameters. ⋯ High-density fractional CO2 laser treatment provides more improvement in burn scars both clinically and histopathologically.

Randomized Controlled Trial Comparative Study
Bupivacaine as an Adjunct to Lidocaine in Mohs Micrographic Surgery: A Prospective Randomized Controlled Trial.
In Mohs micrographic surgery (MMS), the standard local anesthetic agent used is lignocaine with adrenaline. However, MMS can be prolonged; thus reinjections of local anesthetics are often required. ⋯ Adjunctive use of 0.5% bupivacaine with 1:200,000 epinephrine is effective in prolonging anesthesia in MMS.

Randomized, Evaluator-Blinded Study Comparing Safety and Effect of Two Hyaluronic Acid Gels for Lips Enhancement.
Hyaluronic acid (HA) fillers may differ in terms of gel characteristics and ease of use and it is of interest whether this might affect safety and duration of effect. ⋯ Both products achieved durable improvement in lip fullness and aesthetic appearance. A significantly smaller amount of HA-RK was required compared with HA-JV to achieve optimal treatment effect.

Randomized Controlled Trial
Finer Needles Reduce Pain Associated With Injection of Local Anesthetic Using a Minimal Insertion Injection Technique.
The injection of local anesthetic into the skin is often the only memorable event described by the patient after dermatologic procedures. ⋯ This study further validates the use of this technique for the injection of lidocaine and the preference of a 33 gauge over a 30-gauge needle for the initial injection on the face and scalp.
