RESUMEN

INTRODUCTION: Since skin and hair quality are potent vitality signals, and hair growth deficiency can cause significant psychological morbidity. In addition to clearly-defined hair loss disorders, milder forms of hair thinning or hair loss appear to be increasingly common, with a suggestion that sub-optimal diets and stressful lifestyles may be involved. METHODS: Here we assess the value of a dietary marine-extract based dietary supplement in premenopausal women with subclinical hair thinning or hair loss conditions. This multi-site, randomized double-blind, placebo-controlled clinical trial was conducted with impact on hair shedding rate and hair fiber diameter (assessed by phototrichogram) as primary end points upon consumption of the oral supplement compared to a placebo. A total of 96 eligible female subjects were enrolled aged 21-55 years of age from Asian, Caucasian, and Hispanic ethnic backgrounds. RESULTS: This study showed that hair shedding was significantly reduced in the first 3-6 months of daily consumption of the oral supplement. Moreover, phototrichogram image analysis revealed a statistically significant increase in the mean vellus-like hair diameter after 6 months of supplement consumption, when compared to the mean vellus-like hair diameters measured at baseline. DISCUSSION: These results support the view that a nutritional supplement approach may be useful for women in this age group to deal with subclinical hair thinning or hair loss conditions, and those components of this marine extract-based oral supplement may be a useful adjunct.

RESUMEN

BACKGROUND: The effectiveness of psoriasis therapies in real-world settings remains relatively unknown. OBJECTIVE: We sought to compare the effectiveness of less commonly used systemic therapies and commonly used combination therapies for psoriasis. METHODS: This was a multicenter cross-sectional study of 203 patients with plaque psoriasis receiving less common systemic monotherapy (acitretin, cyclosporine, or infliximab) or common combination therapies (adalimumab, etanercept, or infliximab and methotrexate) compared with 168 patients receiving methotrexate evaluated at 1 of 10 US outpatient dermatology sites participating in the Dermatology Clinical Effectiveness Research Network. RESULTS: In adjusted analyses, patients on acitretin (relative response rate 2.01; 95% confidence interval [CI] 1.18-3.41), infliximab (relative response rate 1.93; 95% CI 1.26-2.98), adalimumab and methotrexate (relative response rate 3.04; 95% CI 2.12-4.36), etanercept and methotrexate (relative response rate 2.22; 95% CI 1.25-3.94), and infliximab and methotrexate (relative response rate 1.72; 95% CI 1.10-2.70) were more likely to have clear or almost clear skin compared with patients on methotrexate. There were no differences among treatments when response rate was defined by health-related quality of life. LIMITATIONS: Single time point assessment may result in overestimation of effectiveness. CONCLUSIONS: The efficacy of therapies in clinical trials may overestimate their effectiveness as used in clinical practice. Although physician-reported relative response rates were different among therapies, absolute differences were small and did not correspond to differences in patient-reported outcomes.

RESUMEN

BACKGROUND: Despite widespread dissatisfaction and low treatment persistence in moderate to severe psoriasis, patients' reasons behind treatment discontinuation remain poorly understood. OBJECTIVES: We sought to characterize patient-reported reasons for discontinuing commonly used treatments for moderate to severe psoriasis in real-world clinical practice. METHODS: A total of 1095 patients with moderate to severe plaque psoriasis from 10 dermatology practices who received systemic treatments completed a structured interview. Eleven reasons for treatment discontinuation were assessed for all past treatments. RESULTS: A total of 2231 past treatments were reported. Median treatment duration varied by treatment, ranging from 6.0 to 20.5 months (P < .001). The frequency of each cited discontinuation reasons differed by treatment (all P < .01). Patients who received etanercept (odds ratio [OR] 5.19; 95% confidence interval [CI] 3.23-8.33) and adalimumab (OR 2.10; 95% CI 1.20-3.67) were more likely to cite a loss of efficacy than those who received methotrexate. Patients who received etanercept (OR 0.34; 95% CI 0.23-0.49), adalimumab (OR 0.48; 95% CI 0.30-0.75), and ultraviolet B phototherapy (OR 0.21; 95% CI 0.14-0.31) were less likely to cite side effects than those who received methotrexate, whereas those who received acitretin (OR 1.56; 95% CI 1.08-2.25) were more likely to do so. Patients who underwent ultraviolet B phototherapy were more likely to cite an inability to afford treatment (OR 7.03; 95% CI 3.14-15.72). LIMITATIONS: The study is limited by its reliance on patient recall. CONCLUSIONS: Different patterns of treatment discontinuation reasons are important to consider when developing public policy and evidence-based treatment approaches to improve successful long-term psoriasis control.

RESUMEN

OBJECTIVE: To compare the effectiveness of biologic systemic therapy, nonbiologic systemic therapy, and phototherapy for treatment of psoriasis. DESIGN: A cross-sectional design was used. SETTING: Ten outpatient dermatology sites across the United States participating in the Dermatology Clinical Effectiveness Research Network contributed to the study. PARTICIPANTS: A total of 713 patients with plaque psoriasis receiving systemic monotherapy (ie, methotrexate sodium, adalimumab, etanercept, or ustekinumab) or narrowband UV-B phototherapy. MAIN OUTCOME MEASURES: The primary outcome of the study was clear or almost clear skin on the Physician Global Assessment scale. Secondary outcomes were score on the Psoriasis Area and Severity Index, affected body surface area, and score on the Dermatology Life Quality Index. RESULTS: The proportion of patients with clear or almost clear ratings on the Physician Global Assessment scale differed among treatments: methotrexate (23.8%), adalimumab (47.7%), etanercept (34.2%), ustekinumab (36.1%), and narrowband UV-B (27.6%) (P < .001). In adjusted analyses, patients receiving adalimumab (relative response rate, 2.15; 95% CI, 1.60-2.90), etanercept (1.45; 1.06-1.97), and ustekinumab (1.57; 1.06-2.32) were more likely to have clear or almost clear skin vs patients receiving methotrexate. Patients receiving phototherapy showed no significant difference (1.35; 95% CI, 0.93-1.96) compared with those receiving methotrexate. No response difference was observed with respect to quality of life. Treatment doses were double the recommended doses in 36.1% of patients taking etanercept and 11.8% of those taking adalimumab;10.6% of patients undergoing phototherapy received the recommended treatment frequency. CONCLUSIONS: The effectiveness of psoriasis therapies in clinical practice may be lower than that reported in previous trials. Although relative differences in objective response rates among therapies may exist, absolute differences are small and may not be clinically significant. Dosing of common therapies varied from trial recommendations. These results provide novel benchmarks emphasizing the critical importance of studying effectiveness in real-world practice.

RESUMEN

Vitamin A and its derivatives (commonly termed retinoids) are widely used in topical anti-aging products. Certain retinoids such as retinol and its esters are available without a prescription, while others such as tretinoin are available only via prescription. A randomized, double-blind, controlled clinical study was conducted to compare the efficacy and tolerability of a tri-retinol 1.1% gradual release cream vs. tretinoin 0.025% cream in females with mild-to-moderate facial photodamage. Subjects applied the test product to the entire face in the evening after cleansing in a progressively increasing frequency starting twice weekly for the first week, followed by three times weekly during the second week and then daily as tolerated for the third week and beyond. Treatment was continued for a total of three months. Clinical evaluations and standardized digital photographs were performed at baseline and after four, eight, and 12 weeks of treatment. Self-assessment questionnaires were completed by the subjects at four, eight, and 12 weeks to assess perceived efficacy of the test products. Thirty-four subjects (16: tri-retinol and 18: tretinoin) completed the study. Both test products significantly improved signs of photodamage, including fine and coarse periocular wrinkles, skin firmness, skin tone, mottled pigmentation, tactile roughness, overall photodamage and global photodamage improvement. There were no significant differences in efficacy between the two products for these assessments. The adverse effects (which were graded as mild or less) were those typically seen with topical retinoids. Subjects reported >93 percent overall satisfaction with both products at weeks 8 and 12.

RESUMEN

BACKGROUND: Intense pulsed light (IPL) systems emit non-coherent, polychromatic light and are increasingly used for various dermatologic indications. Although generally regarded as safe therapy, IPL is not without risk. OBJECTIVE: We report a 21-year-old woman who experienced a severe blistering eruption after IPL treatment by a nonphysician. MATERIALS AND METHODS: Case report. RESULTS: The patient reported a 10-year history of persistent redness on her medial and lateral cheeks. She had tried no previous oral or topical therapies. She was diagnosed with rosacea and was treated with IPL. The following day, intense vesiculation and bullae formation occurred, progressing to dramatic facial edema by day 3 and eschar formation by day 5. Ten weeks later, prominent erythema with papularity remained on both cheeks and the lateral neck, with textural change and reticulated dyschromia. She continued to recover 20 weeks after treatment. CONCLUSION: This case most likely represents high-fluence photothermal tissue injury induced by the laser-like qualities of the IPL source, with resulting acantholysis leading to formation of vesicobullae in the context of an uncertain primary diagnosis. This case highlights the potential hazards of IPL therapy and raises questions regarding appropriate use of this medical technology.

RESUMEN

Papular mucinosis is a rare, idiopathic cutaneous mucinosis that is typically chronic and progressively severe. We present a case of a 59-year-old woman with a 6-month history of a dramatic papular eruption on her face and neck, with no associated internal organ involvement. A biopsy specimen demonstrated increased dermal mucin with associated plump fibroblasts, consistent with a diagnosis of papular mucinosis. Multiple therapeutic interventions were unsuccessful, and after 2 years the lesions resolved spontaneously without treatment. During the following 3 years, the patient has had no recurrence of disease.

RESUMEN

The role of gold in allergic contact dermatitis is poorly understood and is a subject of increasing interest. Recent studies demonstrate that gold-positive patch testing is not uncommon, but persistent patch test reactions are rarely reported. We present a case of a 53-year-old woman with a 7-year history of a scattered, pruritic papular dermatitis. Patch testing demonstrated a persistent, positive reaction to gold sodium thiosulfate. The histopathology of the patch test site and that of the cutaneous eruption were similar in nature but differing in severity. No other allergens have been identified, but gold avoidance has not yet resulted in the clearing of her eruption. This case underscores the difficulty in making a clinical correlation despite suggestive clinical pathologic evidence.
