Randomized study comparing the efficacy and tolerance of a lipophillic hydroxy acid derivative of salicylic acid and 5% benzoyl peroxide in the treatment of facial acne vulgaris.
ABSTRACT New topical treatments for acne vulgaris are needed for patients who have tolerance problems with current treatments.
To compare the efficacy and tolerance of a lipophillic derivative of salicylic acid (lipo hydroxy acid or LHA) containing formulation and 5% benzoyl peroxide in subjects with acne vulgaris.
Eighty subjects with mild to moderate facial acne were randomized to receive either the LHA formulation twice a day or benzoyl peroxide once a day for 12 weeks. Efficacy and tolerance were evaluated at days 0, 28, 56 and 87. Results LHA formulation and benzoyl peroxide decreased the number of inflammatory lesions from baseline to week 12 by 44% and 47% and noninflammatory lesions by 19% and 23%, respectively. There was no statistically significant difference between the two treatments (P = 0.748; P = 0.445).
These results suggest that the LHA formulation could be a treatment option to consider in mild to moderate acne vulgaris patients that are intolerant to benzoyl peroxide.

ABSTRACT: A wide range of evidence supports policies which encourage people to cycle more and drive less, for health and environmental reasons. However, the likely energy implications of such a modal shift have remained relatively unexplored. In this paper we generate scenarios for increasing the cycling rate in Sheffield between 2010 and 2020. This is done through the novel application of a simple model, borrowed from population ecology. The analysis suggests that pro-cycling interventions result in energy savings through reduced consumption of fuel and cars, and energy costs through increased demand for food. The cumulative impact is a net reduction in primary energy consumption, the magnitude of which depends on a number of variables which are subject to uncertainty. Based on the evidence presented and analysed in this paper, we conclude that transport policy has a number of important energy implications, some of which remain unexplored. We therefore advocate the formation of closer links between energy policy and transport policy in academia and in practice; our approach provides a simple yet flexible framework for pursuing this aim in the context of modal shift.Energy Policy 04/2011; · 2.74 Impact Factor

ABSTRACT: Objective : The purpose of this study is to study trends in Western(North America and Europe) medical treatments for the acne vulgaris. This study analyzed research on acne vulgaris in PubMed. Methods : We searched PubMed related the latest medical treatments for acne vulgaris. We analyzed 21 research papers and examined published journals, years, countries, and their methods, results, interventions, participants, periods and instruments of assessment. Results : The method of studies was mostly double-blind, randomized controlled trial. There were research papers concerning treatment with light-lazer, topical agents, and oral contraceptives. There were more positive results compared to negative results for efficacy of treatment. The median for number of participants was 364.0 persons. The median for periods was 67.8 days. Assessment for outcomes were lesion counts, adverse effects, VAS, etc. Conclusions : It is necessary to study latest trends of Western medical treatments for acne vulgaris and understand strengths and weaknesses of those. It will be helpful to more in-depth develop clinical treatments of Oriental Medicine for acne vulgaris.The Journal of Korean Medicine Ophthalmology and Otolaryngology and Dermatology. 01/2011; 24(2).

ABSTRACT: Objective: Comparative trials of benzoyl peroxide (BPO) have yielded contradictory results on its effectiveness for acne vulgaris. The aim of the study was to synthesise the evidence for the effectiveness of BPO-containing topical products for facial acne vulgaris. Design: Systematic review. Methods: The Cochrane Central Register of Controlled trials, Cochrane Library, MEDLINE and other relevant databases were searched without publication date or language restriction. Results: We identified 22 trials involving 2212 participants; 12 trials compared BPO as single agent while the other 10 trials compared BPO in combination products. All trials reported lesion count as the outcome measure but only five trials provided numerical data. However, pooling of data from these trials was inappropriate due to variations between trials in terms of acne severity, comparator used and trial duration. Overall the study quality was fair but most studies had some bias particularly in method of random generation and allocation concealment. Although the results provide some evidence that BPO reduces acne-lesion count, the available evidence is not robust enough for firm conclusions. Conclusions: There is no high quality evidence that topical BPO improves facial acne vulgaris, and further research is needed.Journal of Dermatological Treatment 06/2012; · 1.50 Impact Factor
