| Abstract: | Objective: The purpose of this study was to analyze the efficacy and safety of the 585nm pulsed dye laser for the treatment of idiopathic flushing with dysesthesia. Design: This was a retrospective study of patients treated with a 585nm pulsed dye laser with fluences ranging from 3.5 to 7.5J/cm2 (purpura threshold fluences), a pulse duration of 450μsec, and a spot size of 5 or 10mm. Setting: The Ronald 0. Perelman Department of Dermatology at New York University Medical Center. Participants: Ten adult subjects who presented with flushing with dysesthesia. Measurements: Participants subjectively evaluated the decrease in dysesthesia and the number of flushing episodes. The objective response to treatment was evaluated by a single physician using pre- and postoperative photographs. The severity of postoperative erythema was compared with baseline using an ordinal scale ranging from zero (resolution of erythema) to four (76-100% of baseline erythema). Results: The mean number of treatments received by the subjects was seven. The mean fluence was 6.66J/cm2. Subjectively, 100 percent of subjects reported a decrease in dysethesia and the number of flushing episodes. Objectively, subjects demonstrated at least a 62.5-percent reduction in erythema. Conclusion: Laser surgery provided subjective relief of dysesthesia and decreased the number of flushing episodes with a greater than 62-percent objective reduction in the severity of erythema. The 585nm pulsed dye laser is a safe, efficacious treatment for the signs and symptoms of idiopathic flushing with dysesthesia.Flushing is a transient, episodic redness of the face, neck, upper chest, and/or epigastric area that is associated with certain diseases, ingestion of certain drugs or other substances, heat, emotional factors, or physical exertion.1 Blushing is flushing exclusively provoked by an emotional stimulus.2,3 Dysesthesia is defined as an unpleasant, abnormal sensation that is produced by normal stimuli.4Idiopathic flushing is a diagnosis of exclusion.3,5-8 In a subset of patients with idiopathic flushing, dysesthesia may be noted, and patients describe this symptom as a warm, unpleasant, burning sensation. Patients with this constellation of signs and symptoms, which is henceforth referred to as idiopathic flushing with dysesthesia, consistently deny concomitant pruritus. Furthermore, associated signs and symptoms, such as bronchospasm, abdominal cramps, diarrhea, headache, hypotension, or tachycardia, are rare in these patients.The objectives of this study were to define the characteristics of a poorly defined disorder, idiopathic flushing with dysesthesia, and to evaluate the treatment of subjects with this disorder using the 585nm pulsed dye laser. |
