BACKGROUND: Lentigo maligna is a slowly growing melanoma in situ. Current guidelines advise wide local excision with a margin of 5 mm as the treatment of first choice, which has recurrence rates ranging from 6% to 20%.

OBJECTIVES: To determine retrospectively the recurrence rate of lentigo maligna after staged surgical excision.

METHODS: Records of all patients with lentigo maligna treated with our method of staged surgical excision between 2002 and 2011 were retrieved. To identify ...

BACKGROUND: Secukinumab has shown sustained efficacy and safety in several manifestations of psoriasis.

OBJECTIVES: GESTURE investigated the long-term (2·5-year) safety and efficacy of 150 mg and 300 mg subcutaneous secukinumab in 205 patients with moderate-to-severe palmoplantar psoriasis.

METHODS: GESTURE was a randomized, double-blind, placebo-controlled, multicentre, phase IIIb trial conducted across 15 countries. The study was 140 weeks long and consisted of four periods: screening ...

Biological drugs such as the tumour necrosis factor inhibitors have revolutionized the treatment of psoriasis, but some have the potential to induce an unwanted immune response. This immunogenicity may be associated with low trough drug levels, reduced clinical efficacy, reduced drug survival and an increased risk for adverse events. This article presents a literature review of the evidence on immunogenicity of biologics used in the treatment of psoriasis and considers the implications ...

Imiquimod (IMQ) is often used as a topical challenge agent to provoke local skin inflammation. The objective of this study was to develop and refine a rapid, temporary, and reversible human skin inflammation model with IMQ for application in clinical drug development. A randomized, vehicle-controlled, open-label, dose-ranging study was conducted in 16 healthy male subjects. IMQ (5 mg) was applied once daily for 72 hours under occlusion to intact skin (n = 8) or tape stripped (TS) skin (n ...

Omiganan (OMN; a synthetic cationic peptide) and imiquimod (IMQ; a TLR7 agonist) have synergistic effects on interferon responses in vitro. The objective of this study was to translate this to a human model for proof-of-concept, and to explore the potential of OMN add-on treatment for viral skin diseases. Sixteen healthy volunteers received topical IMQ, OMN, or a combination of both for up to 4 days on tape-stripped skin. Skin inflammation was quantified by laser speckle contrast imaging ...

Omiganan is an indolicidin analog with antimicrobial properties that could be beneficial for patients with atopic dermatitis. In this randomized, double-blind, placebo-controlled, phase II trial we explored the efficacy, pharmacodynamics, and safety of topical omiganan once daily in 36 patients with mild to moderate atomic dermatitis. Patients were randomized to apply topical omiganan 1%, omiganan 2.5%, or vehicle gel to one target lesion once daily for 28 consecutive days. Small but ...

Pain is a common side-effect of dermatological laser procedures. Non-invasive anaesthetic drugs and anaesthetic procedures can be used to provide pain relief and increase patient satisfaction and treatment efficacy. However, it remains unclear which method provides the best pain relief. The objective of this systematic review was therefore to assess the efficacy and safety of non-invasive anaesthetic methods during dermatological laser procedures. A systematic literature search was ...

BACKGROUND: Pain is a common adverse effect of dermatological laser procedures. Currently, no standard topical anaesthetic cream exists for deeper dermal laser procedures.

OBJECTIVES: To compare the efficacy of lidocaine/tetracaine cream and lidocaine/prilocaine cream in reducing self-reported pain during deeper dermal laser treatment of acne keloidalis nuchae (AKN) and tattoos.

METHODS: We conducted two randomized, double-blind, controlled clinical trials with intrapatient, split-lesion ...
