Silicone gel enhances the efficacy of Er:YAG laser treatment for atrophic acne scars: A randomized,split-face,evaluator-blinded,placebo-controlled,comparative trial

Background: The effect of topical silicone gel has been studied to prevent scars from burn, postoperative wound and to treat hypertrophic scars. No previous studies have been done to evaluate the efficacy of topical silicone gel on atrophic acne scars. Material and methods: Nineteen patients were treated with three sessions of ablative Er:YAG laser with 1-month intervals. Following each laser treatment, the randomlyassigned silicone gel or placebo was applied in split-face manner. Objective assessments, which included roughness, smoothness, hydration, transepidermal water loss were measured at baseline and prior to each treatment. Subjective assessments by dermatologists and subjects were done at baseline and 1 month after last laser treatment. Results: The laser treatments were well tolerated and resulted in clinical improvements. Topical silicone gel treatment resulted in significantly less roughness at weeks 4 and 12 compared with placebo (p < 0.05). Conclusion: Adding topical silicone gel to ablative Er:YAG laser treatment may provide additional benefits in improving acne scars.     

Effect of an orally administered arotinoid,Ro 15-0778, on sebum production in man

Summary 1,2,3,4-Tetrahydro-1,1,4,4-tetramethyl-y-[(E)-alpha-methylstyryl]-naphtalene (Ro 15-0778), a potent inhibitor of sebaceous gland activity in several animal models has been administered to male volunteers in dosages of 1, 2, 3, and 6 mg/kg/day and 2 g/day for 8 weeks. Sebum production was measured before treatment and after 4 and 8 weeks of therapy. At the dosage levels of 1,2,3, and 6 mg/kg/day there was no decrease in sebum secretion. With the dosage of 2 g/day, a significant decrease in sebum secretion was seen after 8 weeks of treatment with Ro 15-0778.Supported in part by a grant from Hoffmann-LaRoche, Nutley, NJ, and by US Public Health Service Grant AR 22083     

二氧化碳激光治疗中重度痤疮疗效观察

目的对比观察二氧化碳激光治疗中重度痤疮的疗效。方法将180例中重度痤疮患者随机分为治疗组和对照组,治疗组用二氧化碳激光打孔配合口服异维A酸胶丸、阿奇霉素片,外用克林霉素磷酸脂凝胶治疗;对照组仅口服相同药物和外用药治疗。结果治疗组疗效优于对照组(χ2=8.94,P<0.005)。结论二氧化碳激光(CO2)治疗中重度痤疮疗效确切。     

光、激光及射频技术治疗寻常痤疮

痤疮是一种十分常见﹑累及皮脂腺、毛囊的多因素疾病。痤疮治疗中,光疗法具有起效快、疗程短、不良反应少等优点,但这些尚不能完全代替常规的传统治疗,对于那些不愿接受传统治疗、治疗无效或不能耐受的患者,光、激光和射频是其理想选择。     

Demodex folliculorum infestations in common facial dermatoses: acne vulgaris,rosacea, seborrheic dermatitis

BackgroundDemodex mites are found on the skin of many healthy individuals. Demodex mites in high densities are considered to play a pathogenic role.ObjectiveTo investigate the association between Demodex infestation and the three most common facial dermatoses: acne vulgaris, rosacea and seborrheic dermatitis.MethodsThis prospective, observational case-control study included 127 patients (43 with acne vulgaris, 43 with rosacea and 41 with seborrheic dermatitis) and 77 healthy controls. The presence of demodicosis was evaluated by standardized skin surface biopsy in both the patient and control groups.ResultsIn terms of gender and age, no significant difference was found between the patients and controls (p > 0.05). Demodex infestation rates were significantly higher in patients than in controls (p = 0.001). Demodex infestation rates were significantly higher in the rosacea group than acne vulgaris and seborrheic dermatitis groups and controls (p = 0.001; p = 0.024; p = 0.001, respectively). Demodex infestation was found to be significantly higher in the acne vulgaris and seborrheic dermatitis groups than in controls (p = 0.001 and p = 0.001, respectively). No difference was observed between the acne vulgaris and seborrheic dermatitis groups in terms of demodicosis (p = 0.294).Study limitationsSmall sample size is a limitation of the study. The lack of an objective scoring system in the diagnosis of Demodex infestation is another limitation.ConclusionThe findings of the present study emphasize that acne vulgaris, rosacea and seborrheic dermatitis are significantly associated with Demodex infestation. Standardized skin surface biopsy is a practical tool in the determination of Demodex infestation.

An Open-Label, Split-Face Trial Evaluating Efficacy and Safty of Photopneumatic Therapy for the Treatment of Acne

Background

Acne vulgaris is the most common skin disease worldwide, with many available treatment modalities, including oral and topical medications and laser therapy. Recently, a novel device (Isolaz, Pleasanton, CA, USA) that combines vacuum pressure and a broadband light source (400 nm to 1,200 nm) was developed for the treatment of acne.

Objective

To determine the clinical efficacy and safety of photopneumatic therapy for the treatment of acne vulgaris of the face.

Methods

Twenty adults with mild to moderate facial acne vulgaris received 4 successive treatments on one side of the face with a combined photopneumatic device (intense pulsed light: fluence=5.8 J/cm²; negative pressure=iMP mode) at 2 week intervals. Acne lesions on the opposite side of the face were not treated. Lesion counts were performed at baseline, prior to each treatment session, and at 3 months after the final treatment session.

Results

Significant lesion improvements and reduced numbers of acne lesions were observed on the treated side of the faces. Most patients experienced global clinical improvement. No severe side effects occurred during the study, with only a few patients experiencing transient erythema, purpura and/or exacerbation of pre-existing acne.

Conclusion

Photopneumatic therapy is a safe and effective treatment for mild to moderate acne vulgaris.

Cardiff Acne Disability Index in Sarawak, Malaysia

Background

Acne is considered a cosmetic nuisance in Malaysia since no insurance coverage is provided for its treatment. Its psychological impact is unknown.

Objective

The aim of this study is to determine the impact of acne on quality of life and its relationship with severity.

Methods

A cross-sectional study using the Cardiff acne disability index (CADI) and Global Acne Grading System for acne severity grading was done in three government-run dermatology clinics in Sarawak, Malaysia.

Results

The study cohort of 200 patients had a mean CADI score of 5.1. Most of the patients (59.5%) had mild CADI impairment, with the domain of feelings most affected. Patients with a family income <1,000 United States Dollor/month had a higher mean CADI (mean 5.5 vs. 4.4; p=0.04). Females, indigenous groups, and patients with tertiary education tended to have more severe CADI impairment (p>0.05). The correlation between CADI and mild acne severity was low (Pearson correlation coefficient=0.35; p<0.001) but became insignificant for moderate and severe acne.

Conclusion

Acne impairment in Sarawak was moderate and must be addressed. It should be viewed as a psychologically disabling disease requiring optimal management and resource allocation.     

女性更年期痤疮患者的临床特征及睾酮和雌二醇水平的检测

目的 探讨女性更年期痤疮患者血清性激素水平的变化,临床特征及治疗方法。方法 对66例患者的临床特征及治疗进行了观察;测定其中35例患者的血清睾酮和雌二醇水平。结果 患者睾酮、雌二醇与正常人对照组相比较差异无显著性,但睾酮/雌二醇显著高于正常人对照组(P<0.05)。63.6%的患者在更年期发病。皮损以上唇及颏部最多,其次为颊部、额部,多呈散在分布,以粉刺及炎性丘疹或丘脓疱疹为主,少数有炎性结节。多为轻至中度痤疮。78.8%的患者一般治疗即可治愈,其余患者用性激素治愈。结论 更年期因卵巢功能衰退,雌激素分泌减少,雌雄激素比例失衡,肾上腺源性雄激素相对过甚而导致痤疮。更年期痤疮多为轻至中度,皮损以粉刺、炎性丘疹或丘脓疱疹为主,以上唇及颏部最多。绝大多数患者一般治疗即可治愈。
