HautTief Multidisciplinary Educational Program for Patients with Psoriasis or Atopic Dermatitis: A Randomized Controlled Study
BACKGROUND
Improving health-related quality of life (HRQoL), disease severity, and treatment adherence through patient education is an increasingly important, yet relatively new area in dermatology. This randomized controlled trial aims to contribute to this growing area of research by exploring the effects of a 9-week educational program for patients with chronic skin diseases.
OBJECTIVE
The aim of the study was to evaluate the effect of a multidisciplinary educational program on HRQoL and disease severity in patients with psoriasis or atopic dermatitis (AD).
METHODS
Sixty-four patients with diagnosed psoriasis or AD were recruited from University Hospital Zurich and randomized (1:1) to the intervention or control group. To assess HRQoL, the following self-reported questionnaires were used: Dermatology Life Quality Index (DLQI), Skindex-29, EuroQol-5D (EQ-5D), RAND 36-Item Short Form Survey (SF-36), and Beck Depression Inventory (BDI) to measure depression symptoms. Psoriasis Area and Severity Index (PASI) and the Eczema Area and Severity Index (EASI) were used to capture disease extent. These scores were assessed at four study visits, which were performed at baseline and 3, 6, and 9 months after the start of the program.
RESULTS
At month 6, an improvement of at least 25% in BDI was recorded in 15 (68.2%) of 22 patients in the intervention group and 6 (27.3%) of 22 patients in the control group (difference 40.9%, p = 0.016). 53.3% (16 of 30) of patients achieved an improvement in one subdomain of the SF-36 score (role limitations due to emotional problems) at 6-month follow-up, compared with 23.1% (6 of 26) of those not attending the educational program (difference 30.2%; p = 0.042). No significant differences in DLQI, Skindex-29, EQ-5D, PASI, and EASI between both groups at the three time points were found.
CONCLUSION
An educational program may improve HRQoL and depression status of patients with psoriasis or AD
Buffered lidocaine 1%/epinephrine 1:100,000 with sodium bicarbonate (sodium hydrogen carbonate) in a 3:1 ratio is less painful than a 9:1 ratio: A double-blind, randomized, placebo-controlled, crossover trial
Background: Neutralizing (buffering) lidocaine 1%/epinephrine 1:100,000 solution (Lido/Epi) with sodium hydrogen carbonate (NaHCO3) (also called sodium bicarbonate) is widely used to reduce burning sensations during infiltration of Lido/Epi. Optimal mixing ratios have not been systematically investigated.
Objectives: To determine whether a Lido/Epi:NaHCO3 mixing ratio of 3:1 (investigational medicinal product 1) causes less pain during infiltration than a mixing ratio of 9:1 (IMP2) or unbuffered Lido/Epi (IMP3).
Methods: Double-blind, randomized, placebo-controlled, crossover trial (n = 2 × 24) with 4 investigational medicinal products (IMP1-4).
Results: The 3:1 mixing ratio was significantly less painful than the 9:1 ratio (P = .044). Unbuffered Lido/Epi was more painful than the buffered Lido/Epi (P = .001 vs IMP1; P = .033 vs IMP2). IMP4 (NaCl 0.9% [placebo]) was more painful than any of the anesthetic solutions (P = .001 vs IMP1; P = .001 vs IMP2; P = .016 vs IMP3). In all cases, the anesthesia was effective for at least 3 hours.
Limitations: Results of this trial cannot be generalized to other local anesthetics such as prilocaine, bupivacaine, or ropivacaine, which precipitate with NaHCO3 admixtures.
Conclusions: Lido/Epi-NaHCO3 mixtures effectively reduce burning pain during infiltration. The 3:1 mixing ratio is significantly less painful than the 9:1 ratio. Reported findings are of high practical relevance, given the extensive use of local anesthesia today
Radiotherapy as a Treatment Option for Local Disease Control in Primary Cutaneous Diffuse Large B-Cell Lymphoma, Leg Type
BACKGROUND
Primary cutaneous diffuse large B-cell lymphoma, leg type (PCDLBCL, LT) is an aggressive lymphoma variant. Anthracycline-based chemotherapy with rituximab is recommended as first-line treatment. Radiotherapy (RT) has been considered as a therapeutic option for local disease control in patients with solitary or localized lesions.
METHODS
We report the results of a retrospective analysis of PCDLBC, LT patients treated either with RT alone or with physician's decision as first-line treatment, aiming to assess disease progression and/or first recurrence in these treatment groups.
RESULTS
We retrospectively analyzed 20 patients treated either with RT alone (n = 8) or with investigator's choice treatment (n = 12), which included chemotherapy alone or combined with local therapy (RT and wide local excision). Complete response (CR) was achieved in 8 patients from the first group and 9 patients from the second group, with 1 treatment failure. Six patients treated with RT alone progressed with a median time to progression (TTP) of 12.5 months. In the second group, 5 patients progressed with a median TTP of 5.2 months. RT showed good local disease control in both groups without any skin relapses during the follow-up period.
CONCLUSION
RT as first-line monotherapy followed by watchful waiting did not significantly improve the overall risk of disease progression but resulted in good local disease control. After progression, RT could still easily be combined with systemic treatment. The strength of this analysis needs to be evaluated in a larger patient cohort
Topical Over-the-Counter Antiaging Agents: An Update and Systematic Review
Over-the-counter antiaging formulations aim to prevent or minimize the signs of aging skin, and to maintain the benefits obtained from different cosmetic procedures. Even though a huge selection of such products is available on the market, evidence and good clinical practice of the data supporting their use are oftentimes lacking. In this systematic review, the authors reviewed scientific data available in the published literature on the most common ingredients used in antiaging cosmetics, with a particular focus on in vivo studies

Radiotherapy in Periocular Cutaneous Malignancies: A Retrospective Stud
BACKGROUND
Due to the importance of function and cosmetics, periocular skin malignancies represent a therapeutic challenge.
OBJECTIVE
To evaluate the safety and efficacy of radiotherapy (RT) treating periocular skin tumors.
METHODS
Data of patients with periocular tumors treated with grenz or soft X-rays at the University Hospital Zurich, Switzerland, between 2009 and 2014 were reviewed. Basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) with associated in situ lesions, cutaneous melanoma, lentigo maligna (LM), cutaneous lymphoma and Kaposi's sarcoma were included in the analysis.
RESULTS
We found 159 periocular lesions in 145 patients. Overall recurrence was highest for actinic keratosis and Bowen's disease (27%), melanoma (17%) and LM (15%), whereas SCC and BCC showed recurrence in 11 and 10%, respectively. 45% of all recurrences occurred within 12 months after treatment, with a median time to recurrence of 13 months (range 3-73).
CONCLUSION
RT, which provides a good therapeutic response with minimal adverse events, is a therapy option for periocular cutaneous malignancies
