Acute and chronic wound fluids influence keratinocyte function differently.

Wound healing requires a proper functioning of keratinocytes that migrate, proliferate and lead to a competent wound closure. Impaired wound healing might be due to a disturbed keratinocyte function caused by the wound environment. Basically, chronic wound fluid (CWF) differs from acute wound fluid (AWF).

Acute and chronic wound fluids inversely influence adipose-derived stem cell function: molecular insights into impaired wound healing.

Wound healing is a complex biological process that requires a well-orchestrated interaction of mediators as well as resident and infiltrating cells. In this context, mesenchymal stem cells play a crucial role as they are attracted to the wound site and influence tissue regeneration by various mechanisms. In chronic wounds, these processes are disturbed.

Staphylococcus aureus bacteremia after thermal injury: the clinical impact of methicillin resistance.

Objective: To evaluate the impact of methicillin resistance in Staphylococcus aureus bacteremia (SAB) on mortality and length of stay in burn patients.

Design: Retrospective cohort study.

Setting: A 750-bed tertiary care university hospital in Cologne, Germany.

[3-dimensional imaging systems: first experience in planning and documentation of plastic surgery procedures].

A reproducible 3-dimensional photographic system enables plastic surgeons to perform preoperative planning and helps them to understand the patient's expectations. There are a few systems available that allow a reproducible 3-dimensional scans of the patient with direct simulation of the planned procedure. The Vectra Volumetric 3D Surface Imaging® by Canfield® provides such an option and helps the surgeons to document and compare postoperative changes at different time points.

[Microscope-integrated intraoperative indocyanine green angiography in plastic surgery].

The knowledge of tissue perfusion has not only a prognostic value in microvascular surgery but also the intraoperative detection of malperfusion can lead to a quick surgical intervention. Indocyanine green (ICG) angiography allows a topographic analysis of perfusion and is used to assess lymphatic drainage pathways and to analyse the depth of burn injuries. Integrating the technique into an operating microscope enables visualisation of the flow over microanastomoses and allows the assessment of the transit time of blood flow between arterial and venous anastomosis.
