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.To develop and to validate a new photonumeric cellulite severity.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.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%.The proposed photonumeric scale is a consistent, comprehensive, reliable, and reproducible tool for the standardized and objective assessment of the severity of cellulite.The authors hereby affirm that neither the manuscript nor any part of it has been published or is being considered for publication elsewhere.

Vitiligo is an acquired leukoderma that results from the loss of epidermal melanocytes, and is characterized by macules and patches of depigmented skin. With a relatively high rate of prevalence, vitiligo occurs in localized, generalized, or segmental patterns; it can run a rapidly progressive course or remain stationary. The pathogenesis of vitiligo is not yet fully understood, but the autoimmune hypothesis is the most commonly accepted one, based on which, many treatment modalities have been described. Although many therapeutic options exist and new modalities are still emerging, treatment challenges persist, as not all patients respond to available therapies. Variables that affect the choice of treatment include the extent, distribution, and progression rate of the lesions. Another challenge is the lack of a standardized scoring system, which hampers the production of level 1a evidence studies for the treatment of this condition.

BACKGROUND:Photoadaptation to ultraviolet (UV) B phototherapy is due to both pigmentary and nonpigmentary influences.OBJECTIVES:To measure photoadaptation in vitiliginous skin and to compare it with normal pigmented skin.METHODS:Seventeen patients with Fitzpatrick skin phototypes III-VI with vitiligo received six to nine UVB treatments, two to three times weekly. Minimal erythema dose (MED) testing was done at baseline and after all treatments; the percentage change in MED was analysed as a measure of photoadaptation. The percentage decrease in cyclobutane pyrimidine dimers (CPDs) over 24 h after a single exposure of 1 MED was analysed on vitiliginous and normal skin.RESULTS:The mean +/- SD percentage change in MED from before to after treatments was: treated vitiliginous skin 28.5 +/- 39.9% (P = 0.015), treated normal skin 35.9 +/- 49.9% (P = 0.015), untreated vitiliginous skin 11.9 +/- 22.6% (P =0.070), untreated normal skin 25.1 +/- 41.3% (P = 0.041). Of these patients, two-thirds had a positive percentage change in MED (photoadaptation). The mean amount of CPDs induced per megabase of DNA immediately after exposure was significantly higher in vitiliginous skin. The mean +/- SD percentage decrease in CPDs (rate of repair) in 24 h was 35.7 +/- 26.8% in vitiliginous skin (P = 0.027) and 46.2 +/- 19.5% in normally pigmented skin (P = 0.001); no difference was noted in the repair in vitiliginous skin compared with normal skin (P = 0.4).CONCLUSIONS:Photoadaptation in vitiliginous and normal skin was observed in two-thirds of patients. Vitiliginous skin had significantly more CPDs following UVB exposure; the rate of repair of UVB-induced DNA damage was equivalent to that in normal skin.

Inguinal Hyperhidrosis (IH) is a focal and primary form of hyperhidrosis in which the individual has intense sweating in the inguinal region. It usually appears in adolescence, not later than the age of 25, in the most cases, and continues into adulthood. With a sample of 26 patients we described Inguinal Hyperhidrosis (IH). Fifty percent of the patients have a positive family history of this condition or other forms of focal or generalized hyperhidrosis, which suggests a familial pattern. Biopsies performed on the inguinal area in a patient with IH and control patient showed normal histology. Excessive perspiration in the inguinal area significantly affects the quality of life of the patients. It is an embarrassing condition that produces large wet stains on the clothes, therefore making daily activities difficult and compromising the emotional, professional and social life of the affected patients. The therapies commonly used for other forms of focal hyperhidrosis are not yet referred in the literature specifically for IH. Intradermal injections from botulinum toxin provide positive results for the patients and controls the sweating for 6 months or more. It is a simple, safe and effective treatment for this condition and the results significantly improve the quality of life of the affected individuals.
