Immunologically mediated photodermatoses: diagnosis and treatment.

Electromagnetic radiation may cause distinct skin conditions. The immunologically mediated photodermatoses (IMP, previous term: idiopathic photodermatoses) represent a heterogenous group of disorders presenting with pathologic skin reactions caused by optical radiation, particularly in the UVA wavelength region. The exact pathomechanism in IMP remains to be elucidated; however, it is very likely (auto)-immunologic in nature.

Skin conditions in instrumental musicians: a self-reported survey.

Background: Instrumental musicians are a risk group for a variety of skin conditions.

Objectives: To determine the frequency and risk factors of instrument-related skin disorders in musicians.

Method: We mailed an 11-item survey to 19 German universities of music and performing arts.

Review of literature on amicrobial pustulosis of the folds associated with autoimmune disorders.

Amicrobial pustulosis of the folds (APF) is characterized by relapsing, primary aseptic, pustular eruptions mainly affecting the cutaneous folds, scalp, and periorificial regions such as the mouth, external ear canal, and nostrils. APF is a rare condition that has previously been reported in 25 women exhibiting a wide spectrum of autoimmune abnormalities, particularly systemic lupus erythematosus. Histology of the skin lesions usually shows spongiform pustulation in the upper layer of the epidermis and a polymorphonuclear infiltrate in the dermis.

Acute skin alterations following ultraviolet radiation investigated by optical coherence tomography and histology.

Optical coherence tomography (OCT) appears to be a promising technique to study skin in vivo. As part of an exploratory study to investigate UV induced effects non-invasively we aimed to evaluate the kinetics of acute UVB- as well as UVA1 induced skin alterations by means of OCT, and to correlate the results obtained with routine histology. Twelve healthy subjects received daily 60 J/cm2 of UVA1 and 1.

Comparison of histometric data obtained by optical coherence tomography and routine histology.

There is a lack of systematic investigations comparing optical coherence tomography (OCT) with histology. OCT assessments were performed on the upper back of 16 healthy subjects. Epidermis thickness (ET) was assessed using three methods: first, peak-to-valley analysis of the A-scan (ET-OCT-V); second, manual measurements in the OCT images (ET-OCT-M); third, light microscopic determination using routine histology (ET-Histo).

Narrowband UVB phototherapy in skin conditions beyond psoriasis.

Background: Narrowband (NB) UVB phototherapy has been proven to be clearly more effective than broadband UVB and safer and/or more practicable than psoralen-UVA in the management of psoriasis. However, the role of NB UVB seems to be less clear in the management of skin conditions beyond psoriasis.

Objectives: We sought to give an update on clinical experiences in NB UVB of nonpsoriatic skin conditions, and to establish its current position within the spectrum of competing photo(chemo)therapeutic options.

Pimecrolimus 1% cream for anogenital lichen sclerosus in childhood.

Background: Lichen sclerosus is a chronic inflammatory disease with a predilection of the anogenital region. Because of the potential side effects of repeated local application of potent glucocorticosteroids, equally-effective, safer therapeutic options are required, especially in the treatment of children.

Case Presentations: We report on the efficacy of twice-daily application of pimecrolimus 1% cream in four prepubertal girls (range of age: 4 to 9 years) who suffered from anogenital lichen sclerosus.

Contact dermatitis and other skin conditions in instrumental musicians.

Background: The skin is important in the positioning and playing of a musical instrument. During practicing and performing there is a permanent more or less intense contact between the instrument and the musician's skin. Apart from aggravation of predisposed skin diseases (e.
