Severe compensatory hyperhidrosis (CH) in the trunk occurs after sympathectomy in some patients. Limited treatment options for these cases have been proposed, and the overall results have been disappointing, but injection of botulinum toxin-A (BTX-A) is an emerging, reliable treatment method for focal hyperhidrosis. ⋯ BTX-A injection was a well-tolerated, effective, and safe method for treating severe truncal CH, although the considerable cost and limited duration of the treatment effects were major disadvantages.

Review Comparative Study
Comparative physical properties of hyaluronic acid dermal fillers.
Hyaluronic acid (HA) fillers are becoming the material of choice for use in cosmetic soft tissue and dermal correction. HA fillers appear to be similar, but their physical characteristics can be quite different. These differences have the potential to affect the ability of the physician to provide the patient with a natural and enduring result. ⋯ Combining the objective factors that influence filler performance with clinical experience will provide the patient with the optimal product for achieving the best cosmetic result. A careful review of these gel characteristics is essential in determining filler selection, performance, and patient expectations.

Randomized Controlled Trial Multicenter Study Comparative Study
Comparison of injection comfort of a new category of cohesive hyaluronic acid filler with preincorporated lidocaine and a hyaluronic acid filler alone.
A smooth, cohesive, 24-mg/mL hyaluronic acid (HA) gel with uniform consistency, even flow characteristics, and extended duration was designed for injection into the mid to deep dermis. ⋯ The smooth, cohesive HA gel with preincorporated lidocaine increased subject comfort during treatment and improved the injection experience.
