A clinical evaluation of a transparent, absorbent, adhesive wound dressing.

The performance of a transparent absorbent adhesive wound dressing (TAAWD) was observed over 7 days in five plastic surgery clinics across Germany. The study included 47 diverse postoperative linear wounds and donor sites with dry or minimal exudate levels. Data on ease of application and removal, adhesive strength, skin compatibility, conformability to the body, visual wound inspection and parameters of wound assessment were collected and analysed.

Aesthetically pleasant umbilicoplasty.

The umbilicus is an important aesthetic feature of the abdomen and thus calls for an optimized reinsertation technique. Localization and characteristics of the umbilicus were assessed in 137 adults. In addition, age, height, weight, pregnancy, and gender were recorded.

Platelet-rich plasma in burns.

Platelet-rich plasma stimulates angiogenesis, promoting vascular in-growth and fibroblast proliferation. In addition, PRP functions as haemostatic by forming a fibrin clot. Also application of PRP enhances wound-healing in both soft and hard tissue.

Early and long-term evaluation of perfusion changes in free DIEP-flaps for breast reconstruction via IC-view and duplex ultrasound: autonomous or peripheral perfusion?

Controversy surrounds the question whether free flaps remain dependent for blood supply on their vascular pedicle or if there is an autonomization by neovascularization from the surrounding wound bed. This becomes important when flap shaping or repositioning are performed. Our study involved 23 patients who received a deep inferior epigastric perforator (DIEP) flap for breast reconstruction.

The effect of cross-linking of collagen matrices on their angiogenic capability.

The poor vascularization rate of matrices following cell invasion is considered to be one of the main shortcomings of scaffolds used in tissue engineering. In the past decade much effort has been directed towards enhancing the angiogenic potential of biomaterials. A great many studies have appeared reporting about enhancement of vascularization by immobilizing angiogenic factors, such as vascular endothelial growth factor (VEGF) and basic fibroblast growth factor-2 (FGF-2).

Human bone marrow mesenchymal stem cells seeded on modified collagen improved dermal regeneration in vivo.

In the correction of functional and aesthetic impairments, loss of soft connective tissue creates the need for adequate implant material. The reconstruction of defects resulting from radical excisions, trauma, or hereditary diseases has seen the use of combined grafts and flaps. With the aim of minimizing donor site morbidity, new methods have been evaluated.

Human serum from platelet-poor plasma for the culture of primary human preadipocytes.

In adipose tissue engineering, the use of human serum is essential to achieve the goal of an autologous system. Serum from conventional human plasma (SCP) contains platelet-derived growth factor (PDGF), a growth factor known to be both a potent inhibitor of adipose differentiation and also the most important stimulator of proliferation in human serum. Serum from platelet-poor plasma (SPPP) is considered to be PDGF-deprived and should therefore inhibit the differentiation of preadipocytes to adipocytes to a lesser extent.
