Randomized Controlled Trial Comparative StudyPressure garment therapy alone and in combination with silicone for the prevention of hypertrophic scarring: randomized controlled trial with intraindividual comparison.
Published trials evaluating pressure garment and/or silicone therapy as a treatment for hypertrophic burn scarring are of poor quality and highly susceptible to bias. The authors' aim was to compare the efficacy of pressure garment therapy alone and in combination with silicone gel sheet or spray therapy for the prevention of hypertrophic scarring. ⋯ Therapeutic, II.

Randomized Controlled Trial Comparative StudyThe ideal split-thickness skin graft donor-site dressing: a clinical comparative trial of a modified polyurethane dressing and aquacel.
The almost single disadvantage of conventional polyurethane film dressings, uncontrolled leakage, is probably as often described as its numerous advantages for split-thickness skin graft donor sites. This shortcoming can be overcome by perforating the polyurethane dressing, which permits controlled leakage into a secondary absorbent dressing. The study was conducted to compare the polyurethane dressing system and Aquacel, a hydrofiber wound dressing, which also seems to fulfill all criteria of an ideal donor-site dressing. ⋯ Therapeutic, II.

Occipital artery vasculitis not identified as a mechanism of occipital neuralgia-related chronic migraine headaches.
Recent evidence has shown that some cases of occipital neuralgia are attributable to musculofascial compression of the greater occipital nerve and improve with neurolysis. A mechanical interaction at the intersection of the nerve and the occipital artery may also be capable of producing neuralgia, although that mechanism remains one theoretical possibility among several. The authors evaluated the possibility of unrecognized vasculitis of the occipital artery as a potential mechanism of occipital neuralgia arising from the occipital artery/greater occipital nerve junction. ⋯ Therapeutic, IV.

Comparative StudyMicroscale electrode implantation during nerve repair: effects on nerve morphology, electromyography, and recovery of muscle contractile function.
The authors' goal is to develop a peripheral nerve electrode with long-term stability and fidelity for use in nerve/machine interfaces. Microelectromechanical systems use silicon probes that contain multichannel actuators, sensors, and electronics. The authors tested the null hypothesis that implantation of microelectromechanical systems probes does not have a detrimental effect on peripheral nerve function or regeneration. ⋯ The absence of a significant difference between the repair and the repair plus probe groups regarding histology, compound muscle action potential, walking tracks, and muscle force suggests that microelectromechanical systems electrodes are compatible with regenerating axons and show promise for establishing chemical and electrical interfaces with peripheral nerves.

Review Meta AnalysisRisk factors for complications of tissue expansion: a 20-year systematic review and meta-analysis.
Tissue expansion is a widespread and accepted concept in plastic and reconstructive surgery and burn treatment but is also associated with a variety of complications. Most research does not reveal the risk factors for multiple complications of tissue expansion. To determine the risk factors for tissue expansion complications and to evaluate average complication rates, the authors performed a systematic review and meta-analysis of observational studies exploring risk factors for complications of tissue expansion. ⋯ Risk, II.
