RESUMEN

Importance: Use of systemic therapies for moderate to severe psoriasis in children is increasing, but comparative data on their use and toxicities are limited. Objective: To assess patterns of use and relative risks of systemic agents for moderate to severe psoriasis in children. Design, Setting, and Participants: A retrospective review was conducted at 20 centers in North America and Europe, and included all consecutive children with moderate to severe psoriasis who used systemic medications or phototherapy for at least 3 months from December 1, 1990, to September 16, 2014. Main Outcomes and Measures: The minimal core data set included age, sex, severity of psoriasis, systemic interventions, monitoring, adverse events (AEs), and reason for discontinuation. Results: For 390 children (203 girls and 187 boys; mean [SD] age at diagnosis, 8.4 [3.7] years) with psoriasis who used 1 or more systemic medications, the mean interval between diagnosis and starting systemic therapy was 3.0 years. Methotrexate was used by 270 patients (69.2%), biologic agents (primarily etanercept) by 106 (27.2%), acitretin by 57 (14.6%), cyclosporine by 30 (7.7%), fumaric acid esters by 19 (4.9%), and more than 1 medication was used by 73 (18.7%). Of 270 children taking methotrexate, 130 (48.1%) reported 1 or more AEs associated with methotrexate, primarily gastrointestinal (67 [24.8%]). Folic acid 6 days per week (odds ratio, 0.16; 95% CI, 0.06-0.41; P < .001) or 7 days per week (OR, 0.21; 95% CI, 0.08-0.58; P = .003) protected against gastrointestinal AEs more than once-weekly folic acid, regardless of the total weekly dosage. Methotrexate-associated hepatic transaminase elevations were associated with obesity (35 of 270 patients [13.0%]), but a folic acid regimen was not. Injection site reactions occurred in 20 of 106 patients (18.9%) treated with tumor necrosis factor inhibitors, but did not lead to discontinuation of treatment. Having 1 or more AEs related to medication, gastrointestinal AE, laboratory abnormality, or AE leading to discontinuation of the drug was more likely with methotrexate than tumor necrosis factor inhibitors, but having 1 or more infections related to medication (predominantly upper airway) was less likely. Six patients developed a serious treatment-related AE (methotrexate, 3; fumaric acid esters, 2; and adalimumab, 1), but methotrexate and biologic agents were taken for a mean duration that was 2-fold greater than the mean duration for cyclosporine or fumaric acid esters. No patient developed tuberculosis or a malignant neoplasm. Conclusions and Relevance: Medication-related AEs occur less often with tumor necrosis factor inhibitors than with methotrexate. Folic acid administration 6 or 7 times per week protected more against methotrexate-induced gastrointestinal AEs than did weekly administration. A prospective registry is needed to track the long-term risks of systemic agents for pediatric psoriasis.

RESUMEN

BACKGROUND: On 30 January 2012, the US FDA approved vismodegib (Erivedge®, Genentech, CA, USA) for the management of both metastatic and locally advanced basal cell carcinoma. OBJECTIVE: Our objective was to identify evidence of hepatotoxicity with vismodegib in the FDA Adverse Event Reporting System (FAERS) in treated patients in two National Cancer Institute Comprehensive Cancer Centers. METHODS: FAERS was searched for reports dated 1 January 2009 through 31 December 2015 using terms including hedgehog pathway and vismodegib and hepatic-related terms such as liver, jaundice, and hepatitis, among others. Disproportionality analyses with estimates of proportional reporting ratio and empirical Bayesian geometric mean were conducted. A comprehensive literature review was conducted, and the clinical databases at the University of Texas MD Anderson Cancer Center and Robert H. Lurie Comprehensive Cancer Center of Northwestern University were searched. RESULTS: Two cases of severe liver dysfunction were published (Common Terminology Criteria for Adverse Events [CTCAE] class III), and 94 reports of adverse events (AEs) were detected in FAERS, 35 of which were serious AEs. Safety notifications related to hepatotoxicity have not been issued by the manufacturer or the FDA, although vismodegib is listed in LiverTox and the European Medicines Agency website. CONCLUSION: We identified a detectable safety signal for hepatotoxicity for vismodegib within 4 years of FDA approval. Vismodegib should be used in patients with severe liver disease only after careful consideration, and concomitant hepatotoxic medications should be avoided. Rapid dissemination of such safety concerns is expected to result in fewer serious hepatotoxic AEs and more optimal outcomes for patients with cancer receiving vismodegib.

RESUMEN

BACKGROUND: Guided imagery and music can reportedly reduce pain and anxiety during surgery, but no comparative study has been performed for cutaneous surgery to our knowledge. OBJECTIVES: We sought to determine whether short-contact recorded guided imagery or relaxing music could reduce patient pain and anxiety, and surgeon anxiety, during cutaneous surgical procedures. METHODS: Subjects were adults undergoing excisional surgery for basal and squamous cell carcinoma. Randomization was to guided imagery (n = 50), relaxing music (n = 54), or control group (n = 51). Primary outcomes were pain and anxiety measured using visual analog scale and 6-item short-form of the State-Trait Anxiety Inventory, respectively. Secondary outcomes were anxiety of surgeons measured by the 6-item short-form of the State-Trait Anxiety Inventory and physical stress of patients conveyed by vital signs, respectively. RESULTS: There were no significant differences in subjects' pain, anxiety, blood pressure, and pulse rate across groups. In the recorded guided imagery and the relaxing music group, surgeon anxiety was significantly lower than in the control group. LIMITATIONS: Patients could not be blinded. CONCLUSION: Short-contact recorded guided imagery and relaxing music appear not to reduce patient pain and anxiety during excisional procedures under local anesthetic. However, surgeon anxiety may be reduced when patients are listening to such recordings.

RESUMEN

IMPORTANCE: Keratosis pilaris (KP) is a common skin disorder of follicular prominence and erythema that typically affects the proximal extremities, can be disfiguring, and is often resistant to treatment. Shorter-wavelength vascular lasers have been used to reduce the associated erythema but not the textural irregularity. OBJECTIVE: To determine whether the longer-wavelength 810-nm diode laser may be effective for treatment of KP, particularly the associated skin roughness/bumpiness and textural irregularity. DESIGN, SETTING, AND PARTICIPANTS: We performed a split-body, rater-blinded, parallel-group, balanced (1:1), placebo-controlled randomized clinical trial at a dermatology outpatient practice of an urban academic medical center from March 1 to October 1, 2011. We included all patients diagnosed as having KP on both arms and Fitzpatrick skin types I through III. Of the 26 patients who underwent screening, 23 met our enrollment criteria. Of these, 18 patients completed the study, 3 were lost to or unavailable for follow-up, and 2 withdrew owing to inflammatory hyperpigmentation after the laser treatment. INTERVENTIONS: Patients were randomized to receive laser treatment on the right or left arm. Each patient received treatment with the 810-nm pulsed diode laser to the arm randomized to be the treatment site. Treatments were repeated twice, for a total of 3 treatment visits spaced 4 to 5 weeks apart. MAIN OUTCOMES AND MEASURES: The primary outcome measure was the difference in disease severity score, including redness and roughness/bumpiness, with each graded on a scale of 0 (least severe) to 3 (most severe), between the treated and control sites. Two blinded dermatologists rated the sites at 12 weeks after the initial visit. RESULTS: At follow-up, the median redness score reported by the 2 blinded raters for the treatment and control sides was 2.0 (interquartile range [IQR], 1-2; P = .11). The median roughness/bumpiness score was 1.0 (IQR, 1-2) for the treatment sides and 2.0 (IQR, 1-2) for the control sides, a difference of 1 (P = .004). The median overall score combining erythema and roughness/bumpiness was 3.0 (IQR, 2-4) for the treatment sides and 4.0 (IQR, 3-5) for the control sides, a difference of 1 (P = .005). CONCLUSIONS AND RELEVANCE: Three treatments with the 810-nm diode laser may induce significant improvements in skin texture and roughness/bumpiness in KP patients with Fitzpatrick skin types I through III, but baseline erythema is not improved. Complete treatment of erythema and texture in KP may require diode laser treatment combined with other laser or medical modalities that address redness.

RESUMEN

BACKGROUND: Pain is expected during noninvasive skin tightening and can be anxiety provoking, especially for those who have not had prior treatments. OBJECTIVE: To compare pain reported by patients naïve to nonablative skin tightening energy devices with those who were not naive. METHODS AND MATERIALS: The non-naïve group at least three nonablative laser procedures or one nonablative skin tightening procedure, and the naïve group no previous treatments. Four sites at each of two anatomic locations (periorbital and midface or cheek) were treated in each subject with needle prick, pulsed dye laser, radiofrequency, and ultrasound with the order of the interventions randomized. All interventions except ultrasound were also applied to three abdominal sites. The difference in mean pain scores between naïve and nonnaïve subjects were averaged over the anatomic sites. RESULTS: Ten naïve and 10 non-naïve subjects completed study procedures. Mean pain scores ranged from 1.3 to 4.9. The mean for all naïve conditions was 2.3 ± 1.0, vs 2.2 ± 1.4 for non-naïve conditions. There was no overall difference according to group, device, or anatomic area. CONCLUSIONS: There was no significant difference in pain between naïve and non-naïve subjects undergoing cutaneous energy treatments. Individual devices may elicit more pain at specific anatomic locations.

RESUMEN

BACKGROUND: Anticancer therapies cause a wide range of dermatologic adverse events (AE). Although the frequency and severity of these events have been described, their effects on health-related quality of life (QoL) remain poorly understood, and the ones having a greater impact have not been ascertained. OBJECTIVE: To assess QoL in patients on conventional versus targeted anti-cancer therapies using a dermatology-specific questionnaire. METHODS: Patients (n = 283) completed the Skindex-16, a QoL questionnaire measuring the effects on three domains: symptoms, emotions, and function. Patients were grouped into two categories according to the types of oncology treatments received: (1) targeted therapies and (2) non-targeted therapies. Correlations of Skindex-16 scores with type of anti-cancer therapy, number of AEs, and specific dermatologic AEs were investigated. RESULTS: Significant differences between patients treated with targeted versus non-targeted therapy with regards to total Skindex-16 (p = 0.02) and emotion subdomain (p = 0.02) scores were observed. Additionally, patients on targeted therapies experienced a significantly greater number of AEs (p < 0.001) compared with patients on non-targeted therapies. Patients who exhibited epidermal growth factor receptor (EGFR) inhibitor-induced rash had higher Skindex-16 scores (p = 0.009) and higher scores in the symptom (p < 0.001), emotion (p = 0.01), and function (p = 0.001) subdomains than patients without this AE. Similar results were observed for pruritus. All p values were two sided. CONCLUSIONS: Dermatologic AEs are associated with a diminished QoL. Targeted therapies are associated with a significantly increased number of AEs and worse total and emotion Skindex-16 scores in comparison with non-targeted therapies. EGFR inhibitor rash and pruritus produced the greatest negative impact.

RESUMEN

BACKGROUND: Pruritus is a debilitating aspect of atopic dermatitis (AD). Acupuncture has been reported to diminish pruritus, but self-administered acupressure has not been previously evaluated. OBJECTIVES: To evaluate the effectiveness of acupressure on the severity of eczema in a pilot trial. METHODS: Adult patients with AD were randomised to an intervention group (acupressure with standard of care) or a control group (standard of care alone). Subjects in the intervention group performed acupressure using a 1.2 mm acupellet at the LI11 point, applying pressure for 3 min three times per week for 4 weeks. The severity of itching and AD at baseline and at 4 weeks were measured on a visual analogue scale (VAS), the Investigator's Global Assessment (IGA) and the Eczema Area and Severity Index (EASI). RESULTS: Fifteen subjects were enrolled, 12 of whom completed the study between November 2009 and May 2011. There was no significant change between baseline and follow-up survey scores within the control group. In the investigation group there was a decrease in the VAS score (p=0.05) and EASI lichenification (p=0.03), although without significant change in the overall EASI score. Comparison of the scores between groups showed a greater decrease in VAS in the experimental group than in the control group (p=0.04), and a decrease in the IGA (p=0.03) and EASI lichenification score (p=0.03). The overall EASI scores were unchanged. CONCLUSION: Subjects using acupressure at LI11 for 4 weeks had improvement in pruritus and lichenification. Acupressure may prove to be an easily administered alternative treatment, but larger-scale studies are needed to confirm these preliminary findings.

RESUMEN

This case report describes a patient who developed diffuse large B-cell lymphoma (DLBCL) after receiving courses of two investigational biologic agents and cyclosporine followed by more than four years of subcutaneous efalizumab for the treatment of extensive chronic plaque psoriasis. Three years later, the patient remains free of lymphoma and his psoriasis is well controlled with thrice-weekly narrow-band ultraviolet phototherapy. This case emphasizes the importance of continued long-term post-marketing safety surveillance and the early reporting of all possible serious side effects, including cancers, related to the use of any newly available product. In particular, surveillance should focus on the immunomodulating biologic agents in order to identify possible dangerous sequelae.

RESUMEN

BACKGROUND: There is a lack of randomized split-face studies investigating treatments for dermatosis papulosa nigra (DPN) in dark skin. OBJECTIVE: To compare the efficacy, safety, and tolerability of potassium-titanyl-phosphate (KTP) laser with efficacy, safety, and tolerability of electrodesiccation in the treatment of DPN in subjects with Fitzpatrick skin phototypes IV to VI. METHODS: Fourteen subjects with Fitzpatrick skin phototypes IV to VI were randomized to receive two KTP laser treatments 4 weeks apart to half of the face. The contralateral half received two electrodesiccation treatments 4 weeks apart. Response was evaluated by photography reviewed by blinded dermatologists at 4 weeks after the second treatment. A treatment quality questionnaire about side effects and cosmetic outcome was also administered. RESULTS: Difference in improvement of DPN between the KTP side and the electrodesiccation side per each rater (p=.99, p=.54) and per raters combined (p=.50) did not reach statistical significance. There was no treatment difference for subjective effectiveness (p=.06) or subjective confidence improvement (p=.99), although there was a significant treatment difference for subjective discomfort (p=.002) in favor of KTP. Both treatments were well tolerated without significant adverse effects. CONCLUSIONS: Although treatment of DPN with KTP laser and electrodesiccation are comparable in efficacy, KTP laser is preferable for patient comfort.

RESUMEN

OBJECTIVE: An examination glove that delivers aloe vera (AV) gel to the gloved hand was studied in 30 adult females with bilateral occupational dry skin with or without irritant contact dermatitis (with or without erythema, fissures, and excoriations). METHODS: All participants were factory assembly-line workers with repeated superficial skin trauma who attributed their dry, irritated, emollient-dependent skin to a common cause (occupational exposure). Participants were sequentially enrolled (after written informed consent, n = 29 evaluable participants) into an open, contralateral comparison study to evaluate efficacy of AV glove use 8 h/day to one hand versus no use to the opposite hand for 30 days, followed by 30 days rest, followed by 10 days of repeated use. Participant's dorsal hands were documented by standardized photos at baseline, during, and at the end of study. RESULTS: Unblinded investigator baseline assessment rated dry skin as mild to moderate (n = 27), or moderate to severe (n = 2). Mean time to noticeable improvement for the AV glove hand was 3.5 days (range: 2-6 days) whereas marked improvement was 10.4 days (range: 7-17 days) for the AV glove hand. No improvement was detected for nonglove hands. Blinded photo assessment was rated independently by dermatology research staff. End-of-study mean global assessment of AV glove hands versus nonglove hands was 1.3 for AV glove hand (0 = no change, 1 = good [10%-89% global improvement], 2 = marked improvement [90%-100% global improvement]) versus 0 for nonglove hand (P <.0001). Mean global end-of-study assessments by the participants = 2.0 for AV glove hand versus 0 for nonglove hand. CONCLUSION: Dry-coated AV gloves that provide for gradual delivery of AV gel to skin produced a uniformly positive outcome of improved skin integrity, decreased appearance of fine wrinkling, and decreased erythema in the management of occupational dry skin and irritant contact dermatitis.
