Triple combination as adjuvant to cryotherapy in the treatment of solar lentigines: investigator-blinded, randomized clinical trial.

BACKGROUND: Post-inflammatory hyperpigmentation is a frequent concern when treating solar lentigines. OBJECTIVES: To assess the safety and efficacy of a triple combination cream with fluocinolone acetonide 0.01%, hydroquinone 4% and tretinoin 0.05% as adjuvant to cryotherapy in the treatment of solar lentigines in hands dorsum, and in the prevention of post-inflammatory hyperpigmentation after cryotherapy. METHODS: This prospective, randomized, controlled, investigator-blinded, single-centre study enrolled 50 patients. Twenty-five patients received a 2-week daily triple combination cream plus sunscreen pre-treatment and 25 received sunscreen alone. After that, cryotherapy was performed in all patients followed by a 3-week recovery period. After this period, patients received the same initial treatment and were followed up for 8 weeks. Melanin and erythema levels of a target and a control lentigo were objectively measured using a narrowband reflectance spectrophotometer. Lentigines count, colour homogeneity and global improvement were also assessed. RESULTS: The number of solar lentigines reduced in the first 2 weeks only in patients who used the triple combination 25 ± 7 vs. 22 ± 8 (P < 0.0001), and reduced at the end of the study for both groups (P < 0.0001). The melanin levels also reduced in the first 2 weeks only in patients who used the triple combination 297 ± 69 vs. 273 ± 66 (P < 0.0001) and reduced at the end of the study for both groups (P < 0.0001). Erythema and residual blisters from cryotherapy were the reported adverse reactions. CONCLUSION: Triple combination cream can be used to enhance the resolution of solar lentigines, and to significantly reduce melanin levels and lentigines count, improving treatment results. It was well-tolerated and did not increase the occurrence of neither erythema nor other side-effects after the cryotherapy.

A validated photonumeric cellulite severity scale.

BACKGROUND: With recent advances in the treatment of cellulite and localized fat, a comprehensive objective method of measuring cellulite can be potentially useful, especially since important morphological aspects of cellulite are not part of the current classification. Objective To develop and to validate a new photonumeric cellulite severity. METHODS: Based on standardized photographs of 55 patients with cellulite, five key morphological aspects of cellulite were identified. A new photonumeric severity scale was developed and validated. RESULTS: The five key morphological features of cellulite were identified and included the number of depressions, depth of depressions, clinical appearance of evident raised lesions, and presence of flaccidity and the grade of cellulite. Each item was graded from 0 to 3, allowing final classification of cellulite as mild, moderate, and severe. Results for validation of the scale are statistically significant (P < 0.05) and are as follows: intraclass correlation coefficient > 0.7; correlation item-total > 0.7, with the exception of the right buttock; intraclass correlation coefficients 0.881-0.922; Cronbach's alpha 0.851-0.989 and factor analysis 68-76%. CONCLUSION: The proposed photonumeric scale is a consistent, comprehensive, reliable, and reproducible tool for the standardized and objective assessment of the severity of cellulite.
