Efficacy and tolerance of superoxidized solution in the treatment of mild to moderate inflammatory acne. A double-blinded, placebo- controlled, parallel-group, randomized, clinical trial.
J Dermatolog Treat. 2009 Jan 1; 1-4Tirado-Sanchez A, Maria Ponce-Olivera RIntroduction: Superoxidized solution (SOS) is an electrochemically processed aqueous solution manufactured from pure water and sodium chloride. Inflammatory skin disorders have all improved their outcomes with the use of SOS. These indications suggest that SOS could be useful in acne. Methods: A total of 89 patients were enrolled in this double blinded, clinical trial. Patients presented with 10--50 inflammatory lesions (papules and pustules) and an absence of nodulocystic lesions. Results: Improvement was excellent in nine patients (23%) using SOS, compared with five patients (21%) using benzoyl peroxide (BP) (p = 0.378); good in 21 patients (54%) using SOS and 12 patients (50%) using BP (p = 0.794), compared with four patients (18%) taking placebo (p = 0.001); and fair in six patients (15%) using SOS and five patients (21%) using BP (p = 0.415), compared with 12 patients taking placebo (55%) (p = 0.014). In three patients using SOS (8%) the response was poor, compared with two patients (8%) using BP (p = 0.725) and six patients (27%) taking placebo (p = 0.075). We did not need to change a dose during the study period and no systemic effect was observed. Conclusions: We found that SOS is an important choice to treat inflammatory acne, comparable with benzoyl peroxide; however, a larger sample is needed.
In vitro activities of three synthetic peptides derived from epinecidin-1 and an anti-lipopolysaccharide factor against Propionibacterium acnes, Candida albicans, and Trichomonas vaginalis.
Peptides. 2009 Jun; 30(6): 1058-1068Pan CY, Chen JY, Lin TL, Lin CHThe synthetic epinecidin-1(22-42) peptide was derived from positions 22-42 of Epinephelus coioides epinecidin-1. The synthetic SALF(55-76) cyclic peptide (csSALF(55-76)) and SALF(55-76) linear peptide (lsSALF(55-76)) contained sequences from positions 55 to 76 of the Penaeus monodon anti-lipopolysaccharide factor (ALF), respectively. We studied the in vitro activities of epinecidin-1(22-42), csSALF(55-76), and lsSALF(55-76) against Propionibacterium acnes, Candida albicans, and Trichomonas vaginalis. The minimum inhibitory concentrations (MICs) of epinecidin-1(22-42) for the test pathogen strains ranged 12.5-200mug/ml, those of csSALF(55-76) ranged 100-200mug/ml, and those of lsSALF(55-76) ranged 25-200mug/ml. epinecidin-1(22-42) exhibited cytotoxicity towards P. acnes, C. albicans, and T. vaginalis (one strain of which was a metronidazole-resistant strain, while the other strain was not), suggesting that epinecidin-1 functions like a lytic peptide. Similar cytotoxicity was identified against T. vaginalis treated with the csSALF(55-76) and lsSALF(55-76) peptides. The antimicrobial activities of these peptides were confirmed by scanning electron microscopy (SEM), transmission electron microscopy (TEM), a viable cell count assay, and flow cytometric analysis. TEM and SEM examinations of T. vaginalis treated with these three peptides showed that severe swelling preceded cell death and breakage of the outer membrane, and the intracellular inclusion was found to have effluxed extracellularly. This phenomenon was also found with epinecidin-1(22-42) treatment of P. acnes and C. albicans. Our results suggest that the epinecidin-1(22-42), csSALF(55-76), and lsSALF(55-76) peptides may be good candidates for treating trichomoniasis, and epinecidin-1(22-42) may have potential as a drug supporting therapy for acne and candidiasis.
[Hidradenitis suppurativa.]
Tidsskr Nor Laegeforen. 2009 May 14; 129(10): 992-996Tolaas E, Knudsen CW, Sviland L, Tønseth KABACKGROUND: Hidradenitis suppurativa is a chronic inflammatory skin disease characterized by recurrent tender nodules and boils, usually in the armpits and groins. Draining fistulas and hypertrophic scarring are hallmarks of more severe disease. The objective of this article is to review the clinical presentation, diagnostic considerations and treatment of the disease. MATERIAL AND METHODS:. The article is based on a non-systematic literature search in PubMed, review of dermatology textbooks and the author's personal clinical experience. RESULTS: Hidradenitis suppurativa, also known as acne inversa, is a follicular occlusion disease that can severely reduce quality of life. Staphylococci and other pathogenic bacteria frequently colonize the lesions, but the disease is not primarily a bacterial infection. Smoking and obesity can worsen disease activity. Moderate and severe disease is usually treated with excisional surgery. Antibiotics, often tetracyclines, are indicated for mild disease and as an adjunct to surgery in more severe disease. Antibiotics, however, are not curative. New treatment options, such as TNF-α inhibitors and zinc gluconate should still be considered experimental. INTERPRETATION: Hidradenitis suppurativa is probably underdiagnosed. The disease is often recalcitrant to treatment. The effect of medical treatment is not supported by high quality evidence.
Clinical Trial of Dual Treatment with an Ablative Fractional Laser and a Nonablative Laser for the Treatment of Acne Scars in Asian Patients.
Dermatol Surg. 2009 Apr 27; Kim S, Cho KHBACKGROUND Many methods have been proposed for the treatment of acne scars, with variable cosmetic results. Nonablative skin resurfacing is one method that has been proposed. Because of a need for more noticeable clinical improvements, the ablative fractional laser was recently introduced. OBJECTIVE To reduce complications and improve the results of ablative fractional laser resurfacing by combining this treatment of acne scars with nonablative lasers. METHODS A series of 20 patients (skin phototypes IV-V) with atrophic facial acne scars were randomly divided into two groups that received three successive monthly treatments with an ablative fractional laser using high (group A) and low (group B) energy on one facial half and an ablative fractional laser with low energy plus a nonablative resurfacing laser on the other facial half. Patients were evaluated using digital photography at each treatment visit and at 3 months postoperatively. Clinical assessment scores were determined at each treatment session and follow-up visit. RESULTS Although the use of the ablative fractional laser with high energy resulted in an improvement in patients' acne scars, the combination of ablative fractional laser resurfacing and nonablative laser resurfacing yielded the best results, as assessed in photographs as well as by the overall appearance of the acne scars. With the combination method, fewer complications were observed. The authors have indicated no significant interest with commercial supporters.
