A case of cellulitis causing tissue defect during etanercept therapy.

Tumor necrosis factor-alpha (TNF-α) antagonists are employed increasingly during recent years in patients with active rheumatoid arthritis who do not respond to disease-modifying anti-rheumatic drugs. Contraindications such as infections, auto-antibody formation and hypersensitive reactions can be observed during the treatment with TNF-α antagonist drugs. Our case was a 52-year-old woman, followed by several centers for a period of 21 years with a seropositive, erosive and nodular RA diagnosis.

Expansion of surviving skin paddle of neurocutaneous island flaps in rats by VEGF.

The purpose of this study was to investigate whether vascular endothelial growth factor (VEGF) can enlarge the skin paddles of neurocutaneous flaps in rats. Wistar albino rats were used in four groups: Group 1, (n = 10): neurocutaneous island flap; Group 2, (n = 10): neurocutaneous island flap, surgical delay; Group 3, (n = 10): neurocutaneous island flap, VEGF; Group 4, (n = 10): graft. A 3 x 3-cm, neurocutaneous island flap was elevated on the anterolateral skin of the thigh of the rats.
