Auricular electroacupuncture reduces frequency and severity of Raynaud attacks.

Background: Acupuncture has been shown to influence skin perfusion and the subjective cold perception threshold. Therefore, we hypothesized that auricular electroacupuncture (EA) might reduce symptoms in primary Raynaud's phenomenon (PRP).

Methods: Twenty-six patients with PRP received 6 cycles of auricular EA.

Correlation of infrared thermography and skin perfusion in Raynaud patients and in healthy controls.

Background: We aimed to investigate the correlation of infrared thermography (IT) with laser Doppler perfusion imager (LDPI) among patients with primary Raynaud's phenomenon and healthy controls.

Methods: Forty-seven individuals were included: we examined 25 patients with primary Raynaud's phenomenon and 22 age and gender matched healthy controls. IT of the volar surface of the subjects' left hands was performed to record skin temperature while skin perfusion of the same area was determined using LDPI.
