In order to ascertain whether erythropoietin plays a role in early and late repair processes following ischaemic skin flap injury, a dorsal, caudally based skin flap was created in rats. The rats were successively divided into four groups. Group 1 was not treated. The other groups were treated with a subcutaneous administration of 0.9% NaCl saline solution (group 2), a subcutaneous administration ...

Contact allergy to p- tert- butylphenol-formaldehyde resin is not rare. This resin consists of a large number of substances, most of which are unknown. For diagnostic and preventive reasons, the chemical identity of the sensitizers should be known as well as their sensitizing capacities, cross-reaction patterns and presence in the environment. The aim of this study was to investigate the sensitizi ...

Aberrant expression of bcl-gene products has been implicated in the development of non-melanoma skin cancers. Recently, altered expression of ? -smooth muscle actin has been proposed as predictive of tumour behaviour in basal cell carcinomas. The purpose of this study was to compare the aggressive and non-aggressive basal cell carcinomas in terms of bcl-gene products and ? -smooth muscle actin exp ...

We investigated ?-catenin and adenomatous polyposis coli (APC) gene abnormalities in human pilomatricoma, in which a high incidence of ?-catenin gene mutations has been reported. Nucleated tumour cells were microdissected from 20 paraffin-embedded pilomatricomas. Exon 3 of the ?-catenin gene was amplified using polymerase chain reaction and sequencing analysis was performed. Immunostaining for ?-c ...

Current information on the incidence of patch-test positivity and the spectrum of allergens in psoriatics is conflicting. We compared the rates of patch-test positivity to common allergens and topical medicaments in 200 patients suffering from chronic plaque psoriasis (group I) with 51 patients with other non-allergic skin complaints (group II) and 54 patients suspected of having allergic contact ...

The aim of this study was to investigate the suitability and effectiveness of heliotherapy in moderate or severe atopic dermatitis in adults in the Canary Islands. A total of 216 patients participated on 6 different 2- or 3-week heliotherapy trips. Using the Severity Scoring of Atopic Dermatitis Index (SCORAD), the severity of atopic dermatitis was assessed prior to the start of heliotherapy, afte ...

IgA pemphigus is a rare neutrophilic acantholytic skin disorder with only approximately 70 cases reported in the indexed literature to date. Here we describe two patients with IgA pemphigus (subcorneal pustular dermatosis type and intraepithelial neutrophilic type) that to our knowledge are the first Scandinavian patients with this disease. Initially, both patients were misdiagnosed as subcorneal ...

The gastrointestinal tract, particularly the oesophagus, is affected in about half of all patients with systemic sclerosis. Only a few studies so far have dealt with the anorectal tract. We studied the anal function using anorectal manometry in 12 patients with limited systemic sclerosis. We also studied the oesophageal function. For the oesophagus, we measured the difference between intragastric ...

Two previously healthy men who presented with hypotension, constitutional symptoms, and targetoid and discrete spotty erythematous plaques were diagnosed with toxic shock syndrome based on histopathological findings. Specifically, their biopsies revealed necrotic keratinocytes, neutrophils in the epidermis, and neutrophils surrounding dilated superficial vessels. In one case, the diagnosis of toxi ...

Superficial mucoceles are subepithelial extravasations of sialomucin that occur at the epithelial-connective tissue interface and are directly related to minor salivary glands. They have been described in association with oral lichen planus and, exceptionally, with chronic graft versus host disease. Three patients who underwent an allogeneic bone marrow transplantation for a chronic myelogenous le ...

We describe a form of junctional melanocytic neoplasm with a massive production of melanin accumulated in the dermis. The pigment is stored in macrophages, which are by far the most numerous cellular component of the lesion. Another peculiar aspect is the occasional presence of a few melanocytes scattered in a pagetoid pattern above the dermo-epidermal junction in the spinous layer. The histologic ...
