Case series: the effectiveness of Fatty acids from pracaxi oil in a topical silicone base for scar and wound therapy.

ABSTRACT:

Introduction

Wounding affects the integrity of the skin and can ultimately result in skin scarring. Current therapeutic goals of wound treatment focus on the reduction of scar formation and severity. However, scar formation itself varies not only between individuals based on factors such as ethnicity, but also within an individual based on the location of the wound. Therefore, the preparation of customized treatments for individual patients represents an important therapeutic goal in the fields of dermatology and wound healing. The objective of this study was to evaluate the usefulness of fatty acids found in pracaxi oil in a compounded topical anhydrous silicone base for wound and scar therapy.

Methods

Initially, 21 patients with various surgical, traumatic, or burn wounds and scars were enrolled into this case series. Patients applied a compounded topical anhydrous silicone base containing pracaxi oil with or without additional active ingredients, including pentoxifylline, caffeine, tranilast, and mupirocin. Wound/scar photographs taken before and after application of the compounded pracaxi oil topical formulation (with/without additional ingredients) were reviewed and adjudicated by a blinded dermatology reviewer. Improvements in wound size, coloration, and overall appearance before and after treatment were determined. Patient satisfaction was assessed after application of compounded topical formulation using a self-report questionnaire distributed at the time of dispensing.

Results

A total of seven patients were considered available for analysis and were included in the study. In all seven cases, patients reported improvement in scar and wound attributes, including scar and wound size, severity, color, and pain associated with the scar or wound after application of the compounded medicine. On average, patients rated their satisfaction with treatment highly, with a mean score of 10 on a rating scale of 1-10. Retrospective review of wound/scar photographs demonstrated clinically relevant improvements in wound attributes as assessed by a dermatologist. Six of the seven wounds examined were considered "much improved" from baseline.

Conclusions

Application of a compounded anhydrous silicone base containing pracaxi oil alone or in combination with other active substances led to considerable improvements in wound healing and scar attributes and is a potentially useful option in the treatment of surgical, traumatic, or burn wounds and scars.

Project description:BackgroundIn dogs, increasing the tissue n-3 fatty acid (FA) content is associated with potential benefit in some medical conditions, e.g. atopic dermatitis, cancer or heart disease. Therefore effectively and conveniently increasing tissue n-3 FA levels in dogs is of interest. Incorporation of dietary n-3 FA into cell membranes may be studied by FA analysis of erythrocyte membranes (EM), because of the correlation of its FA composition with the FA composition of other cells. Aim of the study was to determine whether an n-3 FA additive added to a control diet is as effective in increasing EM n-3 FA content as feeding an n-3 FA enriched diet. Furthermore the time course of the incorporation of dietary n-3 FA into canine EM was investigated.MethodsThirty dogs were randomly divided into three dietary groups with ten dogs per group. CONT got a dry dog food diet which did not contain EPA or DHA. FO got a dry dog food diet with a high EPA and DHA content. ADD got the CONT diet combined with an n-3 FA additive rich in DHA and EPA. After a feeding period of 12 weeks the additive was discontinued in ADD and these dogs were fed CONT diet for another four weeks to observe washout effects. Erythrocyte lipids were extracted from venous blood samples and their FA composition was determined by gas chromatography. The Mann-Whitney-U-test was used to detect significant differences between the different groups and time points.ResultsAfter one week the proportions of n-3 FA, DHA and EPA were already significantly increased in ADD and FO, apparently reaching a plateau within eight weeks. In our study DHA and not EPA was preferably incorporated into the EM. After discontinuing the administration of the additive in ADD, the n-3 FA values declined slowly without reaching baseline levels within four weeks.ConclusionsIn dogs, an increase of dietary n-3 FA content leads to a rapid inclusion of n-3 FA into EM, regardless of whether the n-3 FA are offered as an enriched diet or as a normal diet supplemented with an n-3 FA additive.
