Since adverse effects due to angiotensin-converting enzyme (ACE) inhibitors frequently occur in cutaneous locations, this review summarizes the spectrum of expected and unexpected adverse effects of these drugs, possible associated mechanisms, and their basic functions for dermatologists. ACE inhibitors block the activity of the metalloproteinase ACE by binding to its active site, thus displacing ...

The cosmetic effect of many mature scars is largely due to their paler appearance than the surrounding skin. The aim of the study was to identify whether melanocytes are present and functioning within pale scars. Cryosections from scar and normal tissue were stained with murine monoclonal antibodies mel-5, c-kit and NKI/beteb to detect melanocytes and precursor melanocytes. The mean number of mel- ...

In analysing radiation-induced connective tissue changes, we studied tenascin expression, elastic fibres, angiogenesis and physio-mechanical properties in irradiated and contralateral healthy skin of radiotherapy-treated breast cancer patients. Skin biopsies were obtained from a radiotherapy-treated skin area and a corresponding non-treated skin area. Haematoxylin-eosin and Verhoeff stainings as w ...

The center, edge and distant regions of the venous leg ulcer differ in inflammatory cell composition, suggesting that these represent different developmental stages. Our goal was to determine which recruitment pathways contribute to the differences in leukocyte composition between the various ulcer regions. The multiple region biopsy approach, which enables to study the different development phase ...

Atopic dermatitis is a multifactorial disorder probably caused by environmental factors in combination with susceptibility genes. The clinical similarity between atopic dermatitis and the eczema manifestation in patients with Wiskott-Aldrich syndrome made the previously identified WAS gene in chromosome subband Xp11.23 an interesting candidate gene for atopic dermatitis. We studied linkage and as ...

A considerable number of people complain about enhanced skin sensitivity. The aim of this study was to investigate the characteristics of subjective statements and objective measurable parameters in subjects with self-estimated enhanced skin susceptibility. Four-hundred-and-twenty volunteers completed a questionnaire form with a self-estimation of skin susceptibility, possible triggering factors a ...

In vitro evidence suggests that intracellular calcium metabolism influences keratinocyte differentiation. However, only a few reports have described exacerbation of psoriasis or psoriasiform eruptions due to intake of calcium channel blockers. We conducted a case-control study to evaluate the association between exposure to calcium channel blockers and psoriasis. Data were obtained through a retro ...

Muscle-related complaints and high creatine kinase (CK) blood levels have been reported in 16-51 % of patients with acne treated with isotretinoin. It has been suggested that this retinoid and exercise have a synergistic effect on muscle. The presence of marked hyperCKemia during the treatment raises concern about rhabdomyolysis. The objective of this report was to evaluate the incidence, course a ...

Hyperkeratotic dermatitis of the palms - also called eczema keratoticum - is a chronic, sometimes disabling condition in middle-aged persons. We carried out a single-blind, placebocontrolled study using acitretin in 29 patients. Fourteen patients received active therapy (30mg acitretin daily) and 15 placebo. All had hyperkeratotic changes of the palms with painful fissures and most had involvement ...

Variegate porphyria is a rare disease caused by a deficiency of protoporphyrinogen oxidase. In most cases, the clinical findings are a combination of systemic symptoms similar to those occurring in acute intermittent porphyria and cutaneous lesions indistinguishable from those of porphyria cutanea tarda. We report on a 24-yearoldwoman with variegateporphyriawho,after intake of lynestrenol, develop ...

We describe a unique patient with mosquito-bite hypersensitivity who had extremely high titres of Epstein-Barr virus antibodies. For many years he developed intractable ulcers on the sites of mosquito-bite. Epstein-Barr virus infection was detected in almost all inflammatory cells in the ulcers and in the peripheral blood lymphocytes by using in situ hybridization to Epstein-Barr virus-encoded sm ...
