Radiofrequency induced thermotherapy (RFITT) of varicose veins compared to endovenous laser treatment (EVLT): a non-randomized prospective study concentrating on occlusion rates, side-effects and clinical outcome.

Background: Radiofrequency obliteration (RFO) and endovenous laser treatment (EVLT) are established techniques in varicose therapy. A novel bipolar RFO technique - Radiofrequency Induced Thermotherapy (RFITT) - was introduced in 2007. Comparative studies of RFITT and EVLT with one year follow-up are missing.

Focal dermal hypoplasia (Goltz-Gorlin syndrome) associated with obstructive papillomatosis of the larynx and hypopharynx.

A 14-year-old girl with focal dermal hypoplasia (Goltz-Gorlin-syndrome) presented with dysphagia, hoarseness, inspiratory stridor, intermittent dry cough and a 10% weight loss. Endoscopy showed that these symptoms were caused by papillomatosis of the hypopharynx and the larynx. The papillomatous masses were resected subtotally by endoscopic laser treatment.

Colocalization of basic fibroblast growth factor and CD44 isoforms containing the variably spliced exon v3 (CD44v3) in normal skin and in epidermal skin cancers.

Previous in vitro studies have shown CD44 isoforms containing the alternatively spliced exon v3 (CD44v3) to be modified with heparan sulphate (HS) and to bind HS-binding basic fibroblast growth factor (bFGF). Here, we demonstrate that exogenously added bFGF is also bound in vivo by CD44v3-positive keratinocytes in normal skin and by tumour cells in basal cell carcinoma and squamous cell carcinoma (SCC), two skin cancers of keratinocyte origin. bFGF binding and CD44v3 expression were colocalized in cultured human normal keratinocytes (HNK) and on the SCC cell line A431.

Metastasizing porocarcinoma of the head with lethal outcome.

Porocarcinoma is a very rare malignant tumor arising from the duct of eccrine sweat glands. Its prognosis is variable. We report on a patient who developed lymph node and multiple distant metastases, and who died of this malignancy only 6 months after the initial diagnosis.

Effects of Mahonia aquifolium ointment on the expression of adhesion, proliferation, and activation markers in the skin of patients with psoriasis.

Objective: To examine the effects of topical therapy with Mahonia aquifolium on the expression of pathogenetically relevant molecules in psoriatic skin by immunohistochemistry.

Study Design: Prospective-randomized, half-side comparison study with subsequent immunohistochemical assessment of biopsies.

Methods: The study areas were treated with Mahonia aquifolium ointment 3( daily and with dithranol in rising concentrations 1( daily, respectively.
