The purpose of this study was to compare the prevalence of trigger fingers in patients with acromegaly versus an unaffected control group. ⋯ Trigger fingers were observed in 25% of the acromegalic patients but in none of the control participants. The A1 pulley was significantly thicker in the acromegalic patients and normalized after 1 year in some who were treated for the disease.

Randomized Controlled Trial Comparative Study
Ultrasound guidance versus electrical stimulation for femoral perineural catheter insertion.
Continuous femoral nerve blocks provide potent analgesia and other benefits after knee surgery. Perineural catheter placement techniques using ultrasound guidance and electrical stimulation (ES) have been described, but the optimal method remains undetermined. We tested the hypothesis that ultrasound guidance alone requires less time for femoral perineural catheter insertion and produces equivalent results compared with ES alone. ⋯ Placement of femoral perineural catheters takes less time with ultrasound guidance compared with ES. In addition, ultrasound guidance produces less procedure-related pain and prevents inadvertent vascular puncture.

Randomized Controlled Trial
Ultrasound guidance versus electrical stimulation for infraclavicular brachial plexus perineural catheter insertion.
Electrical stimulation (ES)- and ultrasound-guided placement techniques have been described for infraclavicular brachial plexus perineural catheters but to our knowledge have never been previously compared in a randomized fashion, leaving the optimal method undetermined. We tested the hypothesis that infraclavicular catheters placed via ultrasound guidance alone require less time for placement and produce equivalent results compared with catheters placed solely via ES. ⋯ Placement of infraclavicular perineural catheters takes less time, is more often successful, and results in fewer inadvertent vascular punctures when using ultrasound guidance compared with ES.
