Plasma lipemia: When the blood donor becomes a patient.

Lipemic plasma donations are not a strange phenomenon to blood bankers. According to quality standards for plasma fractionation, lipemic plasma donations must be discarded. Beyond quality control and inventory aspects, plasma lipemia is also an important risk factor for cardiovascular diseases, acute pancreatitis and is associated with overall mortality, however little attention is given to the management of these donors in the literature.

Topic platelet gel application in chronic diabetic foot ulcers.

Unlabelled: In this observational study performed during 45 months we evaluated patients with chronic and recalcitrant diabetic ulcers who were treated with homologous platelet gel.

Methods: platelet gels were obtained from homologous platelet concentrates that were aliquoted and freezed, being then activated with calcium gluconate and applied in the ulcer after cleaning and debridement. We evaluated patient's comorbidities, wound characteristics (size, tissue, inflammatory signs, pain), number and time of treatment as well as outcome (classified as complete epithelialization; partial improvement- 50% reduction in wound size or pain relief; no evolution).
