Favre-Racouchot syndrome: a novel two-step treatment approach using the carbon dioxide laser.

BACKGROUND: Favre-Racouchot syndrome (FRS) is both disfiguring and difficult to treat. Available medical and surgical therapies are of variable efficacy. Most treatments do not achieve complete resolution and do not show maintenance of therapeutic response. OBJECTIVES: To assess the response to a novel two-step treatment using the CO2 laser in patients with FRS. METHODS: Seven patients with FRS were treated with the CO2 laser in resurfacing mode with manual expression of comedones under infiltrative local anaesthesia. The procedure was completed in one treatment session lasting 30 min and the wound was left to heal by secondary intention. A topical antibiotic was applied to treated areas, which were covered with a nonadherent dressing. All patients were assessed 3 months postoperatively by the operating laser surgeon and a visual assessment of clinical response to treatment in comparison with pretreatment photographs was made. Patient satisfaction was also recorded. RESULTS: All patients achieved complete resolution of FRS. The follow-up duration for our cohort ranged from 8 months to 3 years. Two patients required further treatment within a 2-3-year period from initial treatment. Disease relapse was noted over 1 year after the primary treatment; both these cases were smokers and repeat treatment with similar laser parameters maintained reproducible results. Our longest disease-free follow-up duration was 3 years postprimary treatment. The laser surgeons and patients reported high levels of therapeutic benefit and satisfaction with the results. CONCLUSIONS: This two-step treatment of FRS (CO2 laser resurfacing and manual pressure-induced expression of comedones) is an effective and durable treatment for FRS with an excellent cosmetic outcome. Long-term follow-up beyond 3 years is planned to determine whether later recurrence occurs with this technique.

A study of the efficacy of carbon dioxide and pigment-specific lasers in the treatment of medium-sized congenital melanocytic naevi.

BACKGROUND: Treatment of medium-sized congenital melanocytic naevi (CMN) can be challenging. OBJECTIVES: To present the results of treatment of 55 CMN with the carbon dioxide (CO(2) ) and pigment-specific lasers. METHOD: CO(2) and Q-switched lasers (frequency-doubled Nd:YAG, Nd:YAG and alexandrite) were used to treat 55 CMN. Patients were treated at 3-month intervals until maximum clearance. Clinical response at 3-6 months after final treatment was graded as poor (< 50%), good (50-75%) or excellent (> 75%). Outcomes were evaluated on case note review and questionnaire. RESULTS: Thirty-six of the 55 CMN were macular and 19 were mammillated. Twenty-seven CMN were present on the head and neck. For macular CMN, outcomes were better for truncal CMN. Scarring and pallor were seen in three lower limb macular CMN treated with a CO(2) laser. Mammillated CMN on the head and neck showed most improvement. Pigment-specific lasers were of no additional benefit. Repigmentation occurred in 6% of macular and 21% of mammillated CMN. Partial or complete regimentation of CMN was reported by 46% of patients. CONCLUSIONS: Compared with macular CMN, mammillated CMN show a marginally better response to laser treatment. CMN on the limbs respond poorly. Pigment-specific lasers do not lighten mammillated CMN. Adverse effects can occur with CO(2) laser treatment of macular CMN on lower limbs.

Efficacy of topical tacrolimus 0.3% in clobetasol propionate 0.05% ointment in therapy-resistant cutaneous lupus erythematosus: a cohort study.

BACKGROUND: Despite a range of available topical and systemic therapies, treatment of cutaneous lupus erythematosus (CLE) can be challenging. Objectives. To evaluate the efficacy of a specially formulated preparation of tacrolimus 0.3% in clobetasol propionate 0.05% ointment (TCPO) in the treatment of CLE. METHODS: Case notes of 13 patients with treatment-resistant CLE (11 discoid LE, 1 systemic LE and 1 subacute cutaneous LE) who had used twice-daily TCPO (TCPO group) were reviewed. These were compared with five similar patients with resistant CLE who had been given 0.1% tacrolimus ointment alone (TO group). RESULTS: In the TCPO group (mean treatment duration 20 months, range 1-72), a good or excellent response was seen in five and six patients, respectively; one patient showed slight improvement. Telangiectasia and acne were observed in two patients. No systemic side-effects were noted. In the TO group (mean treatment duration 6 months, range 1-24), one patient showed good improvement and two showed slight improvement. CONCLUSION: The results of our small retrospective study suggest that TCPO may be more effective than either 0.1% tacrolimus or clobetasol propionate 0.05% ointment monotherapy in the treatment of recalcitrant CLE. Randomized controlled trials are needed to confirm these preliminary findings.

Carbon dioxide laser treatment of rhinophyma: a review of 124 patients.

BACKGROUND: Rhinophyma is a progressive, localized or generalized nasal deformity resulting from hypertrophy of sebaceous and connective tissue. The CO(2) laser has been used for treatment of rhinophyma, but the long-term efficacy of the treatment is unknown. OBJECTIVES: To review the outcome of 124 patients with rhinophyma treated with the CO(2) laser between 1996 and 2008 in our centre. PATIENTS AND METHODS: Exuberant sebaceous tissue was ablated using the Sharplan 40C CO(2) laser (Sharplan Lasers UK Ltd, London, U.K.) under local anaesthesia. The technique varied with the severity of rhinophyma; the laser was used in a continuous mode to debulk the larger rhinophymas, and in a resurfacing mode (Silk Touch scanner; Sharplan, 4-7-mm spot at 20-40 W) or continuous mode (10-20 W using a defocused 2-3-mm beam) to reshape the nasal contours. Outcomes were determined by case notes, clinical review and questionnaire. RESULTS: Laser treatment was completed in a single session in 115 of 124 patients. All patients were reviewed 3 months post-treatment. Results were classified as good to excellent in 118 and poor in six patients. All patients were sent a satisfaction questionnaire in 2008 and 52 patients replied. Patients reported high levels of satisfaction following treatment. The post-treatment response at 3-month review was maintained long term. The main complications were pain associated with injection of local anaesthetic, scarring and hypopigmentation (four patients) and open pores (two patients). CONCLUSIONS: The CO(2) laser is an effective and durable treatment for rhinophyma. Treatment carries a low risk of side-effects and is associated with high patient acceptability and satisfaction.

Pulsed-dye laser treatment of angioma serpiginosum.

Angioma serpiginosum (AS) is a rare, benign, vascular disorder comprising nonblanchable punctate red to purple lesions in a gyrate or serpiginous configuration. Tunable pulsed-dye laser (PDL) therapy has been successfully used in the treatment of AS. We report our results of treatment of 12 AS sites in eight patients who were treated with PDL. After an average of 3.75 treatments, complete resolution of AS was seen in five lesions, an excellent response in four and a good response in three. Self-limiting hyperpigmentation at the test sites was noted in two patients. This study provides further evidence of the efficacy of PDL for treatment of AS.

Outcomes of treatment of nine cases of recalcitrant severe hidradenitis suppurativa with carbon dioxide laser.

BACKGROUND: Hidradenitis suppurativa (HS) is a chronic and often a recalcitrant inflammatory skin condition. OBJECTIVES: To present the results of carbon dioxide (CO2) laser treatment of recalcitrant HS in nine patients who had failed to improve on medical and other surgical treatments. METHODS: HS lesions consisting of abscesses, sinuses and granulation tissue were completely excised using the cutting mode of a CO2 laser, leaving only healthy residual subcutaneous fat. The wounds were closed by primary intention where possible and left to granulate otherwise. Outcomes were determined by clinical review and questionnaire. RESULTS: Twenty-seven sites were treated in 19 sessions on nine patients. Seven procedures were performed under general anaesthesia and 12 under local. All patients rated their postoperative discomfort as less or equal to their preoperative state. Seven of the nine patients had complete remission for 12 months or longer after their last laser treatment and ceased all medications. High levels of patient satisfaction were reported with CO2 laser treatment. The main complication was axillary scar contracture in two patients but this was insufficient to limit limb movement. CONCLUSIONS: CO2 laser treatment should be considered as a treatment option in recalcitrant HS, where multiple medical treatments have been ineffective.

The choice of topical steroids--a personal view.

Topical steroids are the most commonly prescribed drugs for use on the skin. Various factors affecting the choice of such a steroid in the UK are considered and explained.

Cutaneous necrosis due to cetrimide application.

Reports of necrosis caused by quaternary ammonium compounds, such as cetrimide, are rare. The case is reported of a 77-year-old woman who was admitted to hospital for four months with cutaneous necrosis of the left foot and leg owing to the topical application of cetrimide powder.

Cryosurgery in the treatment of lichen sclerosus et atrophicus of the vulva.

Twelve patients with lichen sclerosus et atrophicus of the vulva were treated by a nitrous oxide cryoprobe. All had had severe itching which was relieved in the post-operative period in 75% and for 3 years in 50%. Eight had histologically proven leukoplakia which cleared post-operatively in five (62.5%) and remained clear at three years in four (50%). In one patient pruritus, leukoplakia and ultimately squamous carcinoma appeared.

Evaluation of the Nd/YAG laser for treatment of amateur and professional tattoos.

Two hundred and twenty-one amateur tattoos and 27 professional tattoos were treated with a Nd/YAG laser (lambda 1064 nm and 532 nm). The response was expressed as the percentage area cleared of tattoo. Seventy-nine per cent of amateur black tattoos were > or = 75% clear after one to five treatments (mean 2) at 1064 nm. The response of professional tattoos was slower and less complete. Seventy-four per cent of black professional tattoos were > or = 75% clear after one to 11 treatments (mean 6.3) at 1064 nm. Red tattoos responded well to 532 nm and were > or = 75% clear after one to five treatments. Yellow, orange, blue and green tattoos were resistant to treatment. Side-effects included minor scarring in 1.2% of tattoos and transient pigmentary changes in 77% of patients.

Report of nine cases of accidental injury to man with Freund's complete adjuvant.

Nine cases of accidental injury with Freund's complete adjuvant to man are reported. One case is reported in detail and the other eight have been seen and reviewed retrospectively. Reactions developed in Mantoux positive individuals, who injected Freund's complete adjuvant with another protein. However, not all such injections produced the reaction. Treatment was unsuccessful, although one reaction may have been aborted by early surgical excision of the site of injection.

Urticaria successfully treated by desensitization with grass pollen extract.

We report a case of severe incapacitating seasonal urticaria and angioedema in an 11-year-old boy due to grass pollen sensitivity, who responded well to desensitization therapy with Timothy grass pollen extract.

Cushing's syndrome and pituitary-adrenal suppression due to clobetasol propionate.

Widespread application of clobetasol propionate resulted in suppression of the hypothalamic pituitary axis in four patients. Three patients showed Cushigoid features and developed symptoms of adrenocortical insufficiency on withdrawal of clobetasol.

Alopecia totalis in a patient with Crohn's disease and its treatment with azathioprine.

A patient with Crohn's disease and alopecia totalis is described. Despite relative inactivity of the Crohn's disease, treatment with azathioprine was commenced. This led to complete regrowth of hair which was lost when the drug was discontinued. Re-institution of azathioprine restored hair to normal again and the patient has since declined to try stopping the drug despite the knowledge of potential side effects.
