Randomized Controlled Trial Comparative Study
Randomized, double-blind, prospective study to compare topical 5-aminolaevulinic acid methylester with topical 5-aminolaevulinic acid photodynamic therapy for extensive scalp actinic keratosis.
5-aminolaevlinic acid methylester (MAL) and 5-aminolaevulinic acid (ALA) photodynamic therapy (PDT) are both effective treatment options for actinic keratosis (AK). While MAL is significantly more expensive than ALA, no studies have directly compared their efficacy in the treatment of extensive scalp AK. ⋯ This study demonstrates that both ALA-PDT and MAL-PDT result in a significant reduction in scalp AK. There is no significant difference in efficacy. However, ALA-PDT is more painful than MAL-PDT in the treatment of extensive scalp AK.

Artificial reduction in transepidermal water loss improves skin barrier function.
Artificial reduction of abnormal transepidermal water loss (TEWL) is considered to improve skin diseases associated with a defective barrier function. Treatment of the skin with moisturizers is also known to influence skin barrier function. Whether or not differences in occlusion between creams contribute to their effects on the skin barrier function is unknown. ⋯ Differences between creams in terms of their effect on skin barrier function cannot be solely explained by their occlusive properties.

Idiopathic hyperhidrosis may be a disabling condition causing emotional stress and negative impact on a patient's quality of life. Oral anticholinergics are one of the treatments available. There are few published data on the use of the anticholinergic drug glycopyrronium bromide (glycopyrrolate) given orally in the treatment of hyperhidrosis. ⋯ A prospective clinical study to compare the efficacy and side-effects of oral anticholinergics is warranted.

Pruritus in patients with psoriasis has been reported to be more common than previously thought. ⋯ Pruritus is a common feature in psoriasis. Considering the well-known roles of neuropeptides in pathogenesis of both psoriasis and pruritus, increased SPR, TrkA and CGRPR may be involved in the pathogenesis of pruritus in psoriasis and in the severity of psoriasis.

Multicenter Study
Prevalence of physical symptoms of itch, pain and fatigue in patients with skin diseases in general practice.
Physical symptoms of skin diseases have been shown to negatively affect patients' wellbeing. Although insight into physical symptoms accompanying skin diseases is relevant for the management and treatment of skin diseases, the prevalence of physical symptoms among patients with skin diseases is a rather unexplored territory. ⋯ Itch and fatigue and, to a somewhat lesser extent, pain have a high prevalence among patients with skin diseases. Clinicians should be encouraged to carefully assess itch, pain and fatigue in patients with skin diseases, and where appropriate focus treatment to these symptoms.
