Therapy of percutaneous infection around craniofacial implants.

This study sought to develop treatment strategies for managing percutaneous infection around craniofacial implants. The present general pathogen situation together with a bacterial resistance were determined in 57 infected peri-implant sites. Forty-four implants were randomly assigned for wound cleaning and split into three groups-two with local antibiotics of proven efficacy and one with 3% hydrogen peroxide (H2O2).

Impact of microenvironment on the growth of primary human epidermal cells.

Although the conditions for in vitro cultivation of adult stem cells and tissue are easily standardized, little is known about the optimal conditions for biointegration after transfer of the tissue graft, playing an important role in the treatment of defects especially soft-tissue skin injuries. To examine the influence of the microenvironment, we investigated the doubling time of primary epithelial cells in relation to the culture medium. Serum from patients of different age groups (n = 15, <20 years; n = 9, >20 years; and fetal calf serum) was pooled independently of age and added to culture medium of epithelial cells from a skin donor (10%).

Cultured epithelial autografts in the treatment of facial skin defects: clinical outcome.

Purpose: To report the treatment of facial skin defects by cultured epithelial autografts and its clinical outcome.

Patients And Methods: Between 2002 and 2003, 18 patients with secondary facial skin defects (after tumor excision, trauma, or due to chronic wound healing dysfunction) were successfully treated with autologous cultivated keratinocytes. Overall, 12 patients were included in our study.

Spontaneous scalp arteriovenous fistula in a child with hartnup disease.

Purpose: To report the endovascular treatment of a spontaneous scalp arteriovenous fistula (AVF) in a child with Hartnup disease.

Case Report: A 6-year-old girl with Hartnup disease presented with recurrent attacks of intense, migraine-like, right-sided headache; a tender, pulsatile small mass was observed in the scalp. Selective digital subtraction angiography revealed a high-flow scalp AVF fed by the frontal branch of the right superficial temporal artery draining via the scalp veins.

Endovascular management of a mandibular arteriovenous malformation in a patient with severe hemophilia a.

The unusual case of a mandibular arteriovenous malformation in a patient with severe hemophilia A and hepatitis C is reported. Supplementary substitution of various coagulation factors allowed direct puncture and intralesional injection of a liquid adhesive, resulting in complete anatomic and clinical cure without peri- or postoperative bleeding. Replacement therapy providing normal levels of relevant coagulation factors enables endovascular treatment in a safe and effective manner in hemophiliac patients.
