Acne Medications

Clin Exp Dermatol. 2009 Jun 22; Madan V, August PJ, Chalmers RJSummary Background. Despite a range of available topical and systemic therapies, treatment of cutaneous lupus erythematosus (CLE) can be challenging. Objectives. To evaluate the efficacy of a specially formulated preparation of tacrolimus 0.3% in clobetasol propionate 0.05% ointment (TCPO) in the treatment of CLE. Methods. Case notes of 13 patients with treatment-resistant CLE (11 discoid LE, 1 systemic LE and 1 subacute cutaneous LE) who had used twice-daily TCPO (TCPO group) were reviewed. These were compared with five similar patients with resistant CLE who had been given 0.1% tacrolimus ointment alone (TO group). Results. In the TCPO group (mean treatment duration 20 months, range 1-72), a good or excellent response was seen in five and six patients, respectively; one patient showed slight improvement. Telangiectasia and acne were observed in two patients. No systemic side-effects were noted. In the TO group (mean treatment duration 6 months, range 1-24), one patient showed good improvement and two showed slight improvement. Conclusion. The results of our small retrospective study suggest that TCPO may be more effective than either 0.1% tacrolimus or clobetasol propionate 0.05% ointment monotherapy in the treatment of recalcitrant CLE. Randomized controlled trials are needed to confirm these preliminary findings.

Gynecol Endocrinol. 2009 Jun 23; 1-6Zacche MM, Caputo L, Filippis S, Zacche G, Dindelli M, Ferrari ABackground. Polycystic ovary syndrome (PCOS) is the most common endocrine cause of hirsutism, acne and pattern alopecia, often characterised by ovulation disorders (usually manifested as oligo- or amenorrhea). In addition, 30-40% of women with PCOS have impaired glucose tolerance, and a defect in the insulin signalling pathway seems to be implicated in the pathogenesis of insulin resistance. For this reason, insulin-lowering medications represent novel approach in women with PCOS. The aim of this study was to evaluate the effects of myo-inositol (MYO), an isoform of inositol, belonging to the vitamin B complex, in the treatment of cutaneous disorders like hirsutism and acne. Methods. Fifty patients with PCOS were enrolled in the study. BMI, LH, FSH, insulin, HOMA index, androstenedione, testosterone, free testosterone, hirsutism and acne were evaluated at the baseline and after receiving MYO therapy for 6 months. Results. After 3 months of MYO administration, plasma LH, testosterone, free testosterone, insulin and HOMA index resulted significantly reduced; no significant changes were observed in plasma FSH and androstenedione levels. Both hirsutism and acne decreased after 6 months of therapy. Discussion. MYO administration is a simple and safe treatment that ameliorates the metabolic profile of patients with PCOS, reducing hirsutism and acne.

Clin Exp Dermatol. 2009 Jun 22; Law MP, Chuh AA, Molinari N, Lee ASummary Background. The association between diet and acne vulgaris has long been suggested but remains unproven in western medicine. In contrast, the diet-acne relationship is considered important in traditional Chinese medicine (TCM). Aim. To investigate the association between diet and acne, using a TCM approach. Methods. Using a cross-sectional study of 322 entrants to a university in Hong Kong, China, we examined the participants' clinical severity of acne using the Global Acne Grading System and the participants' yin and yang scores using a quantitative method. We then divided them into two groups, a yin-predominant group (yin-PG) and a yang-predominant group (yang-PG) before the diet-acne relationship was investigated. Results. In total, 82 (25.2%) participants were in the clinical acne group and 240 (74.5%) were in the reference group. There were 155 (48.1%) participants in the yin-PG and 167 (51.9%) in the yang-PG group. No association of diet and acne was found when the participants were considered as a homogenous group. In yin-PG, intake of foods from street stalls (P = 0.04) was significantly associated with a lower incidence of acne. In yang-PG, the intake of desserts (P = 0.04) and fresh fruit juices (P = 0.02) was significantly associated with a higher incidence of acne, whereas the intake of dairy and soy products (P = 0.04) was significantly associated with a lower incidence of acne. Conclusions. The application of a TCM approach led to the detection of significant associations between diet and the incidence of acne.

Telemed J E Health. 2009 Jun; 15(5): 426-30Bergman H, Tsai KY, Seo SJ, Kvedar JC, Watson AJDigital imaging of dermatology patients is a novel approach to remote data collection. A number of assessment tools have been developed to grade acne severity and to track clinical progress over time. Although these tools have been validated when used in a face-to-face setting, their efficacy and reliability when used to assess digital images have not been examined. The main purpose of this study was to determine whether specific assessment tools designed to grade acne during face-to-face visits can be applied to the evaluation of digital images. The secondary purpose was to ascertain whether images obtained by subjects are of adequate quality to allow such assessments to be made. Three hundred (300) digital images of patients with mild to moderate facial inflammatory acne from an ongoing randomized-controlled study were included in this analysis. These images were obtained from 20 patients and consisted of sets of 3 images taken over time. Of these images, 120 images were captured by subjects themselves and 180 were taken by study staff. Subjects were asked to retake their photographs if the initial images were deemed of poor quality by study staff. Images were evaluated by two dermatologists-in-training using validated acne assessment measures: Total Inflammatory Lesion Count, Leeds technique, and the Investigator's Global Assessment. Reliability of raters was evaluated using correlation coefficients and kappa statistics. Of the different acne assessment measures tested, the inter-rater reliability was highest for the total inflammatory lesion count (r = 0.871), but low for the Leeds technique (kappa = 0.381) and global assessment (kappa = 0.3119). Raters were able to evaluate over 89% of all images using each type of acne assessment measure despite the fact that images obtained by study staff were of higher quality than those obtained by patients (p < 0.001). Several existing clinical assessment measures can be used to evaluate digital images obtained from subjects with inflammatory acne lesions. The level of inter-rater agreement is highly variable across assessment measures, and we found the Total Inflammatory Lesion Count to be the most reliable. This measure could be used to allow a dermatologist to remotely track a patient's progress over time.
