Thoracic sympathetic block for the treatment of complex regional pain syndrome type I: a double-blind randomized controlled study.

Pain relief in complex regional pain syndrome (CRPS) remains a major challenge, in part due to the lack of evidence-based treatment trials specific for this condition. We performed a long-term randomized, double-blinded active-control study to evaluate the efficacy of thoracic sympathetic block (TSB) for upper limb type I CRPS. The study objective was to evaluate the analgesic effect of TSB in CRPS.

Histamine iontophoresis on the viability of random skin flap in rats.

Purpose: To evaluate the effects of the histamine iontophoresis on the random skin flap viability in rats.

Methods: Sixty adult male Wistar rats were used. A cranially-based dorsal skin flap measuring 10 x 4 cm was raised and a plastic barrier was placed between the flap and its bed.
