Systemic toxicity from topically applied lidocaine in conjunction with fractional photothermolysis.

BACKGROUND: Topical anesthetics, unlike injectable anesthetics, can be applied painlessly and can provide sufficient pain control to maintain patient comfort throughout a variety of laser procedures. Although the use of topical lidocaine is considered relatively safe, instances of cardiotoxic and neurotoxic adverse events have been reported to occur. OBSERVATIONS: A 52-year-old woman underwent fractional photothermolysis for management of severe hypopigmentation and scarring of several years' duration. Shortly after termination of treatment to her face and neck, which required prolonged exposure to a 30% lidocaine gel compound both before and during surgery, she developed clinical signs and symptoms consistent with systemic lidocaine toxicity. The results of laboratory studies confirmed serum lidocaine levels within the toxic range. We postulate that the combination of the high concentration of topical lidocaine required to achieve sufficient anesthesia, together with the laser-induced disruption in epidermal barrier function, may have been responsible for this phenomenon. CONCLUSIONS: Application of a 30% topical lidocaine gel to a limited area in conjunction with fractional photothermolysis may generate serum lidocaine levels high enough to elicit systemic toxicity. Laser surgeons should be alert to this phenomenon, particularly in patients with underlying hepatic, endocrine, cardiac, or central nervous system/psychiatric dysfunction; in patients with a low body mass index; and in patients who are taking medications that may interfere with hepatic lidocaine metabolism.

Skin rejuvenation using intense pulsed light: a randomized controlled split-face trial with blinded response evaluation.

OBJECTIVE: To evaluate efficacy and adverse effects of intense pulsed light rejuvenation in a homogeneous group of patients. DESIGN: Randomized controlled split-face trial. SETTING: University dermatology department. PATIENTS: Thirty-two female volunteers with Fitzpatrick skin type I through III and class I or II rhytids. INTERVENTIONS: Subjects were randomized to 3 intense pulsed light treatments at 1-month intervals or to no treatment of right or left sides of the face. MAIN OUTCOME MEASURES: Primary end points were skin texture and rhytids. Secondary end points were telangiectasia, irregular pigmentation, and adverse effects. Efficacy was evaluated by patient self-assessments and by blinded clinical and photographic evaluations up to 9 months after final treatment. Adverse effects were assessed clinically and by noninvasive skin reflectance measurements. RESULTS: Skin texture was significantly improved at all clinical assessments except at the 6-month examination (P<.006). The improvements peaked at 1 month after treatment, at which time 23 (82%) of 28 patients had better appearances of treated vs untreated sides. Most patients obtained mild or moderate improvements, and 16 patients (58%) self-reported mild or moderate efficacy on skin texture. Rhytids were not significantly different on treated vs untreated sides, and 19 patients (68%) reported uncertain or no efficacy on rhytids. Significant improvements of telangiectasia (P<.001) and irregular pigmentation (P<.03) were found at all assessments. Three patients withdrew from the study because of pain related to treatment. CONCLUSIONS: Three intense pulsed light treatments improved skin texture, telangiectasia, and irregular pigmentation but had no efficacy on rhytids. Adverse events were minimal, but included scar in 1 patient.

Bilateral facial capillary malformation associated with eye and brain abnormalities.

OBJECTIVE: To establish whether the prognosis of bilateral facial capillary malformation (BFCM) is worse compared with that of unilateral facial port-wine stain. DESIGN: Retrospective study. SETTING: Paediatric Dermatology Department, Great Ormond Street Hospital for Children NHS Trust, a tertiary referral center for vascular anomalies. PATIENTS: A cohort of 350 children who presented with facial CM was seen between January 1, 1994, and June 30, 2004. Twenty-seven children with BFCM were identified. A control group of 27 children with unilateral CM was randomly selected from the total cohort. MAIN OUTCOME MEASURES: Demographic, clinical, and radiographic characteristics were recorded and compared between the 2 groups: age at presentation, sex, distribution, extension, extrafacial lesions, glaucoma, ipsilateral leptomeningeal angiomatosis, and epilepsy. The recorded information was collected from the database of the Paediatric Dermatology Department, the hospital records, and the patients' photographs. RESULTS: Compared with the 27 children with unilateral facial CM, the 27 with BFCM showed a higher frequency of association with extrafacial lesions (17 [63%] vs 6 [22%]), glaucoma (21 [78%] vs 2 [7%]), and ipsilateral leptomeningeal angiomatosis (14 [52%] vs 2 [7%]). All patients who had BFCM with bilateral and complete involvement of the ophthalmic area had ipsilateral leptomeningeal angiomatosis. CONCLUSION: Patients with BFCM must be considered as a group with a worse prognosis compared with patients with unilateral facial CM.

The histopathology of closed and open comedones of Favre-Racouchot disease.

OBJECTIVE: To determine the distinction between a comedo and an infundibular cyst of Favre-Racouchot disease. SETTING: A university hospital. PATIENTS: From the 8 patients included in the study, 19 cysts and comedones were evaluated. MAIN OUTCOME MEASURE: The distinguishing features between the cysts and comedones of Favre-Racouchot disease. RESULTS: All lesions were histologically indistinguishable from the primary comedones of acne vulgaris, except for the presence of a marked actinic elastosis in the surrounding dermis. The presence of a variable number of hair shafts and an abundant amount of bacteria, which was positive in the results of Gram staining and periodic acid-Schiff reaction and intermingled with sebum and eosinophilic laminated horny material within the dilated infundibulum, characterizes a comedo and differentiates it from an infundibular cyst. CONCLUSIONS: The cysts and comedones of Favre-Racouchot disease are closed and open comedones. They can be easily differentiated from an infundibular cyst by the histopathologic features rather than by the connection to the surface.
