RESUMEN

Skin laxity and Oedematous Fibrosclerotic Panniculopathy are common issues affecting the women population. Finding and developing treatments to counteract ageing indications and conform to social norms of beauty has been increasingly important in aesthetic medicine in recent times. Many non-invasive techniques, including radiofrequency, lasers, and ultrasounds, have been created. This study used a multi-handpiece device with laser (808 nm) and ultrasound (37 kHz) handpieces, as well as radiofrequency and various temperature-controlling applicators depending on the body site (3 or 6 tips). Based on their clinical features, 12 women with skin laxity on their arms, face/neck area, or lower limbs at phases I-III were divided evenly into two study groups. The majority of patients reported 'Excellent-3' treatment outcomes after it was over, and their impression of the course of treatment was generally better than the investigators. An objective analysis of the anthropometric measurement data shows a progressive decrease in circumferences, tight plicometry and body weight. In summary, the specific use of an radiofrequency handpiece with a temperature sensor decreased the likelihood of side effects, even with a small study population group. This increased patient compliance with treatment and overall satisfaction with the outcomes.

RESUMEN

Background: The mechanism of action of fractional carbon dioxide (CO2) laser in the management of skin scarring is stimulation of collagen and fibroblasts in the dermis, resulting in remodeling and shrinking of the skin. Objective: The purpose of this research is to assess the safety and performance of a new CO2 laser scanner for treatment of acne scars. Methods: The study was carried out on 20 patients of both sexes, with a mean age of 25.7 ± 6.7 years. To assess the performance and safety of this new CO2 scanner, a preclinical histological evaluation was done. A clinical evaluation of acne scars was performed using Goodman and Baron's quantitative global acne scarring grading system (GBQGASGS) and a crusting scale where crusting scores ranged from 1 = none to 4 = severe. Digital photographs were taken to obtain esthetic results. Results: GBQGASGS showed a significant improvement in patients' scars and the treatment was well tolerated, with no lasting side effects. Conclusions: The new scanner seems to be an effective and safe device for skin scarring treatment, speeding up the healing time of scars.

RESUMEN

Tattoo colorants decompose under solar radiation and when exposed to laser light for their removal, leading to the accumulation in the dermis of toxic products. Aim of this study was to develop lipid microparticles (LMs) loaded with the colorant, Acid Red 87 (C.I. 45380) used in tattoo inks, and to investigate the effect of this system on the photostability of the colorant under simulated sunlight or laser irradiation. LMs loaded with C.I. 45380 were prepared by melt emulsification using tristearin and phosphatidylcholine as excipients. They were characterized by optical microscopy, laser diffraction, X-ray diffraction and release studies. Free C.I. 45380 and the colorant-loaded LMs were irradiated with a solar simulator or a Q-switched laser. Irradiation with a solar simulator demonstrated that photodecomposition of C.I. 45380 was markedly reduced by incorporation of the dye in the LMs, from 20.5 ± 4.6% to 1.3 ± 1.8%. Conversely, the laser-induced degradation of the colorant (30.1 ± 6.6%) was not significantly influenced by encapsulation in the LMs (the encapsulated C.I. 45380 loss was 27.4 ± 5.5%). Incorporation of C.I. 45380 in lipid microparticles enhances the photostability under sunlight of tattoo inks containing this colorant, without affecting its laser-induced degradation and hence laser removal efficiency.

RESUMEN

Background: Treatment of actinic keratosis (AK) and field cancerization with photodynamic therapy (PDT) is an effective therapeutic approach with a significant reduction in the number of AK lesions (-75% or more) associated with a significant cosmetic improvement of the photodamaged skin. Recently, also, the daylight PDT (DL-PDT) has proven to be as effective as the conventional PDT (C-PDT), but with a better tolerability. After C-PDT and DL-PDT it is advised to use photoprotection strategies to improve the clinical evolution and prevent the appearance of new AK lesions that usually appear 3-6 months after the last phototherapy session. However, there are no robust clinical data regarding the type of photoprotection to be used (SPF level, duration of treatment, etc.) after successful PDT.Study aim: The present study (ATHENA trial) evaluated the efficacy and tolerability of a topical product based on 0.8% piroxicam and 50+ solar filters (ACTX), applied twice a day as sequential therapy after C-PDT or DL-PDT on the evolution of AK lesions number compared to the use of very high photoprotection products commonly used in this clinical setting (SPF50+ or SPF100+ associated with photolyase) (Standard Sunscreens: SS group). Subjects and methods: This was a multicenter, randomized, two-arm, prospective controlled, assessor-masked outcome evaluation, parallel group (1:1), pragmatic study of 6 months duration in patients with multiple AK lesions suitable for photodynamic therapy. The objectives of the study were the evaluation of the evolution of the number of AK lesions during the period of treatment/application of the study products, and the Investigator global clinical assessment score (IGA score; 4: marked improvement, 3: good, 2: moderate; 1 no improvement; 0: worsening) 2, 3, and 6 months after the last PDT session. A total of 68 subjects (50 men, 18 women; mean age 70 years), 34 assigned to treatment with ACTX and 34 to treatment with SS (17 treated with a SPF50+ and 17 with a photolyase-containing SPF100+ products), were enrolled in the study.Results: The number of AK lesions present before C-PDT/DL-PDT was 11.8 ± 5.8 in the ACTX group and 12.4 ± 6.9 in the SS group. In both groups, there was a progressive reduction of AK lesions observed at baseline (-86% and -87% after 2 months and -88% and -83% at month 3 in ACTX and in the SS group, respectively). At month 6, AK mean lesion number was 1.8 ± 1.6 in the ACTX and 3.2 ± 2.3 in the SS group; this difference was statistically significant (p = 0.03). The IGA score at the end of the study was 3.2 in the ACTX and 2.7 in the SS group (p = 0.05). The percentage of subjects with an IGA score of 4/3 (very good or good) was 81% in the ACTX and 55% in the SS group (p = 0.06).Conclusion: In subjects with AK treated with C-PDT or DL-PDT, a "medicalized" photoprotection treatment is associated with a favorable clinical outcome with progressive reduction of lesions. In contrast to a very high photoprotection (SPF50+ or SPF100+/photolyase), the use of piroxicam 0.8%/SPF 50+ is associated with a significantly greater improvement in clinical evolution of AK lesions.

RESUMEN

INTRODUCTION: Sunscreen protection in subjects with actinic keratosis (AK) is highly recommended to prevent clinical evolution of this in situ skin cancer condition. Use of topical anti-cyclooxygenase drugs such as diclofenac and piroxicam reduces the number of lesions and improves the cancerization field. A film-forming medical device in a cream formulation containing organic and inorganic sun-filters (50+ SPF) and piroxicam 0.8% (ACTX) has shown in a pilot, single-center, open trial to reduce AK lesions improving the cancerization field. AIM: We evaluated in a multicenter, assessor-blinded, 3 month trial the efficacy of ACTX in AK. METHODS: A total of 70 subjects with at least three AK lesions on the scalp or face were enrolled after written informed consent. Primary outcomes of the study were the clinical evolution of number of AK lesions on a target zone area and the evolution of dermoscopy features of the target lesion, assessing erythema, scaling, pigmentation, and follicular plug, using a 5 point score (from 0 to 4; maximum score: 16). Lesion count and dermoscopy score were evaluated in a blind fashion assessing digital color high definition coded images. A secondary outcome was the Investigator Global Score (IGS) of clinical evolution of the target area using a 7 point scale from -2 (significantly worse) to +4 (completely cured). IGS was evaluated in an open fashion. Subjects were instructed to apply the cream twice daily on the target area, using one finger-tip unit for the treatment of a 35 cm2 area. RESULTS: All but one subject (40 men and 30 women, mean age 73 years) concluded the study period. At baseline the mean (±SD) number of AK lesions in the target area were 7.0 (5.9) with a median value of 5 and the dermoscopy score of the target lesion was 7.0 (2.3) with a median value of 7.0. ACTX treatment reduced AK lesions to 3.2 (2.9), (p = .0001; Wilcoxon Test), representing a 55% relative reduction. Dermoscopy score was reduced to 3.3 (2.6) (p = .0001) (a reduction of 53%). The IGS after ACTX treatment was +1.9 (1.1), with a median of 2.0. A total of 86% of subjects showed a clinical improvement of IGS (≥1) with a very significant/complete clearance (score +3 or +4) in 42% subjects. No change or a worsening of AK lesions was observed in 14% of the subjects. The product was well tolerated. No serious adverse events were reported during the duration of the trial. CONCLUSION: In this multicenter, assessor-blinded trial, the use of a film-forming medical device with sun protection and anti-inflammatory actions was effective in reducing AK lesions and improving the dermoscopy aspect of the target lesion in 86% of treated subjects. A head-to-head trial evaluating the efficacy of this medical device in comparison with diclofenac is warranted to establish whether this therapeutic approach could offer additional advantages in term of AK lesion reduction compared to an established topical treatment.

RESUMEN

The macrozoobenthos living around two offshore gas platforms, Barbara NW (pB) and Calipso (pC) located in the northwestern Adriatic Sea were investigated for three years after their construction to detect eventual effects due to the platforms. The sampling stations were spaced at increasing distance from the platforms up to 1000 m. Both multivariate and univariate analysis showed an initial defaunation (short-term effect) at pB and within a 120 m radius at pC. A general recovery in terms of abundance, species richness and diversity was observed for the benthic communities after one year. During the third monitoring year a mussel mound developed at both the platforms (longer-term effect) extending up to 30 m from pC, whereas similar soft-bottom communities were found at all the other distances. The geographical position plays an important role in the "timing" of the above effects. Moreover, despite the different environmental features, a 3-year monitoring plan can be effective to evaluate the potential impact on benthic communities of offshore gas platforms in the north-central Adriatic Sea.
