Tacrolimus in Solution as an Option to Inflammatory Conditions of the Scalp.

INTRODUCTION: Several dermatological diseases lead to inflammatory conditions of the scalp. Most of these afflictions are recalcitrant and require long term maintenance treatment. OBJECTIVES: We present a case series where topical tacrolimus was used in a solution vehicle for these conditions. METHODS: A total of 22 patients (aged 24-90 years) with confirmed diagnosis of lichen planus pilaris (LPP), discoid lupus (DL), frontal fibrosing alopecia (FFA), erosive pustulosis of the scalp (EPS) or folliculitis decalvans (FD) were evaluated and treated with tacrolimus solution (0.1%) applied twice daily for 1 month, then once daily for another month and alternate days for 4 months. Efficacy was evaluated by an investigator global assessment, clinical and dermoscopic evaluation at weeks 4, 8 and 24. The safety assessment included monitoring of all adverse events. RESULTS: The study included 13 patients with LPP, 2 with DL, 2 with FD, 2 with EPS and 3 with AFF. After 1 month, 14 patients (63.6%) had a good response and 7 (31.8%) had excellent response. After 2 months, 16 patients (72.7%) had excellent response, and this response was persistent after 6 months of treatment. CONCLUSIONS: Tacrolimus in solution, even if not yet commercially available, was an effective and well tolerated alternative for the maintenance treatment of inflammatory conditions of the scalp.

Real-World Experience With Topical 5-Fluorouracil 4% (40 mg/g) Cream for the Treatment of Actinic Keratosis.

INTRODUCTION: 5-fluorouracil (5-FU) is one of the most effective topical treatments for actinic keratosis (AK). A new 4% formulation of 5-FU was recently approved in Europe. OBJECTIVES: This study aimed at evaluating 4% 5-FU cream safety and effectiveness in a real-world setting. METHODS: Adult AK patients were retrospectively selected from the University of Campania Dermatology Unit database. Selection criteria included a diagnosis of non-hyperkeratotic, non-hypertrophic AK (Olsen grade I and II) of the face, ears, and/or scalp, treatment with 4% 5-FU once daily for 4 weeks, and at least 3 follow-up visits (4 and 8 weeks after treatment initiation, and 6 months after treatment end). The primary objectives were to evaluate AK lesions improvement at 8 weeks and relapse rate at 6 months. Patient-reported erythema and burning sensation intensity were also assessed at 4 weeks. RESULTS: Ninety-eight patients were included in this analysis (male/female 80/18, mean age 74.7 years). AK lesions improvement at 8 weeks resulted complete or significant in 74.5% and 20.4% of the patients, respectively. At 6 months, 65.3% of the patients did not show AK relapses. Burning sensation at 4 weeks was reported as light, moderate, or absent by 44.9%, 22.4%, and 31.6% of the patients, respectively. Erythema was reported as light, moderate, or absent by 37.8%, 51%, and 10% of the patients, respectively. Burning sensation and erythema disappeared gradually during follow-up. No other side effects were reported. CONCLUSIONS: In this real-world study 4% 5-FU proved to be highly effective for AK lesions clearance with a favorable safety profile.

Real-life experience with oral oxybutynin long-term continuous therapy in severe hyperhidrosis and systematic review of the literature.

Hyperhidrosis is a disorder of excessive sweating severely impacting on patient's quality of life (Qol). Several studies have been published about oral oxybutynin, but no studies focused on the achievement of complete clinical and Qol response. The aim of this study was to report our real-life experience with oral oxybutynin in patients with severe hyperhidrosis significantly affecting their Qol. In this cohort retrospective study, we enrolled, in a 3-year period, patients affected by severe hyperhidrosis with poor Qol, continuously treated with oral oxybutynin. Our outcome was the obtainment of complete clinical and Qol improvement. A systematic review of the literature was also performed reporting efficacy and safety of oral oxybutynin for primary hyperhidrosis. We enrolled 62 patients, of which 53 (85.5%) received a mean daily dose of 10 mg and nine (15.5%) of 5 mg. Complete clinical response was achieved in 77.4% (48/62) of cases, while complete Qol improvement occurred in 51.6% (32/62) of cases. Adverse events were only reported as mild, with dry mouth being the most frequently observed (16.1%). Kaplan-Meier survival analysis highlighted that both median clinical and Qol complete responses were reached after 1 year of continuous therapy with oral oxybutynin. The main limitation of our study is the small number of patients enrolled. Long-term therapy with oral oxybutynin for severe hyperhidrosis, continuously administered at a mean daily dosage of 5 to 10 mg, allowed the majority of our patients to reach both clinical and Qol complete improvement, without significant adverse events.

Plasma radiofrequency ablation for treatment of benign skin lesions: Clinical and reflectance confocal microscopy outcomes.

BACKGROUND: In the latest few years, plasma radiofrequency ablation has turned out a good option for treatment of several benign skin lesions. The technique can be easily performed to treat skin lesions with limited tissue invasion and no residual scars or hypo/hyperpigmentation areas. OBJECTIVE: The aim of this study was to assess the effects of plasma radiofrequency ablation in treatment of benign skin lesions, through clinical and reflectance confocal microscopy outcomes. METHODS: Six patients who presented benign skin lesions underwent long-wave plasma radiofrequency ablation treatment with DAS medical device (Technolux, Italia). Reflectance confocal microscopy analysis was performed at baseline and after 1 month. RESULTS: The treatment was well tolerated; only a slight erythema and a thin crust on the treated area were referred for 3-7 days after treatment. After one month from treatments, we observed the complete disappearance of the lesions and no significant signs of inflammation, redness, hypo/hyperpigmentation, or scars on the site of the treated areas; these clinical data were also confirmed by reflectance confocal microscopy analysis. CONCLUSIONS: Long-wave plasma radiofrequency ablation actually can be considered a well-tolerated, painless, safe, effective, and low-cost procedure for skin treatments.

Efficacy and safety of secukinumab in a psoriatic patient affected by comorbid metabolic disorders.

Psoriasis is a common, chronic, immune-mediated disease occurring more frequently in association with comorbid metabolic disorders. The management of patients with multiple organ dysfunction is challenging since the use of all conventional systemic agents is limited or contraindicated. In the last two decades, the introduction of biological drugs has revolutionized treatment paradigms of psoriasis and enabled numerous patients to achieve disease control with an acceptable safety profile. We reported for the first time the case of a 66-year-old female psoriatic patient affected by myocardial infarction, hypertension, chronic renal failure, hyperthyroidsm and morbid obesity, who experienced remarkable improvement in skin and joint synthoms and metabolic parameters after 48 weeks of secukinumab monotherapy. In our patient, secukinumab was well tolerated and no side effects have been observed. Our observation suggests that secukinumab could be a safe therapeutic option in patients with organ impairment or failure in which the majority of conventional systemic agents are contraindicated.
