RESUMO
Atopic dermatitis is a chronic inflammatory disease that mainly affects children, causing a strong impact on the quality of life. The most affected subjects live in urban areas or in developed countries, with prevalence increased up to 15%-20% in children and from 1% to 3% in adults during the past 30 years. Most adults had the first signs of illness before the age of 5, many of them before the age of 1. Many therapies in use are associated with side effects and often induce intolerance; therefore, many studies are based on the search for topical products that have an effective benefit, are well tolerated and appreciated by patients. Natural products are expected to have promising prospects in the management of atopy. Cardiospermum halicacabum is a member of the Sapindaceae family that seems to express its cortisone-like anti-inflammatory activity by activating phospholipase A2 while maintaining the stability of cell membranes, an effect due to the presence of phytosterols, having an affinity for lipids in the epidermis and cell membranes. We report our experience during a 15 days observational clinical study aimed to demonstrate efficacy and safety of the treatment with HALICAR: a cream containing C. halicacabum. Clinical data indicates that the treatment with HALICAR leads to positive effects in subjects with dermatitis of various degrees, regardless of which concomitant treatment is considered.

Daylight-photodynamic therapy (D-PDT) and ingenol mebutate (IM) are novel therapies directed to actinic keratoses (AK). The purpose of our study was to compare effectiveness, tolerability, cosmetic outcome and patient preference of D-PDT versus IM in the treatment of grade I and II AK. Twenty-seven patients with AK on the face or scalp were enrolled. Each patient received, in a 25 cm(2) target area, D-PDT on right side and IM on left side. Overall 323 AK were treated. Both target areas achieved complete response in 40.47% of the cases and average AK clearance rate was similar for D-PDT and IM (p=0.74). In D-PDT areas mean grade II AK clearance rate was lower compared with that of grade I AK (p=0.015). In IM areas grade I and II AK average clearance rates were similar (p=0.28). At week 1 and month 1, mean local skin responses (LSR) score were higher in areas treated with IM. IM areas showed more severe pain and cosmetic sequelae. D-PDT had similar effectiveness to IM, even if IM demonstrated higher grade II AK clearance rate. Tolerability profile was superior for D-PDT in terms of LSR and pain. D-PDT was more cosmetically acceptable. Patients preferred D-PDT to IM in most cases.

Actinic cheilitis (AC) is a common premalignant condition that requires an effective treatment to reduce the risk of malignant transformation. Photodynamic therapy (PDT) has been recently added to the armamentarium available for AC treatment. Daylight PDT (D-PDT) is a novel PDT modality in which the activation of the topical photosensitizer is induced by the exposure to natural daylight instead of artificial light sources without preliminary occlusion. This simplified procedure was found to be more tolerated as compared to conventional PDT. We report our preliminary experience on the use of D-PDT using methyl-aminolevulinate cream in 10 patients with refractory AC of the lower lip. Patients received two consecutive D-PDT sessions with an interval of 7-14 days. At 3 months after therapy, a complete response was observed in seven patients, with sustained results in five patients over an observational period of 6-12 months. Treatment was well tolerated.

BACKGROUND: Daylight photodynamic therapy (D-PDT) is a novel modality of PDT in which the activation of the topical photosensitizer is mediated by the exposure to daylight instead of artificial light sources without the need of preliminary occlusion. This simplified modality has been found to be well tolerated. We report our experience with D-PDT in patients with actinic keratoses (AK). METHODS: The data relative to 53 patients consecutively treated for AK with a single session of D-PDT using methyl aminolaevulinate cream were retrospectively reviewed. Most patients had grade I and/or II AK on the face and/or the scalp. Some patients had additional cutaneous lesions, including non-melanoma skin cancers, in the AK-associated field, that were simultaneously treated with D-PDT. RESULTS: At 3 months, a complete response (AK number=0) was achieved by 54.7% of patients, and the lesion clearance rate was 82.7%. Treatment was more effective in thinner lesions, with complete clearance involving 93% of grade I AK. At 6-9 months after treatment, response was maintained in 85.7% of the lesions previously cleared, and 72.4% of the initial complete responders did not relapse. No relevant effect of D-PDT was instead observed on senile lentigo, nodular basal cell carcinoma and squamous cell carcinoma, whereas a complete response was seen in 7 of the 9 superficial basal cell carcinomas treated. Local skin reactions mostly consisted in slight erythema. Mild symptoms (burning and tingling sensations) were reported by 12 patients. CONCLUSIONS: These preliminary results support the favorable efficacy and tolerability profile of D-PDT, which seems to be an interesting, valid, and convenient therapeutic option for AK, and possibly also for superficial basal cell carcinomas.
