ReviewCollective review: bioactive implants coated with poly(D,L-lactide) and growth factors IGF-I, TGF-beta1, or BMP-2 for stimulation of fracture healing.
Demographic data reveal that due to the increasing aging of the population, complications with the musculoskeletal system will increase in the next years. One major problem in orthopedic and trauma surgery are the delayed healing or non-unions of long bone fractures. The exogenous application of growth factors can stimulate the bone healing to reduce these complications. ⋯ All investigated growth factors stimulated the fracture healing as assessed with biomechanical tests and histological analysis. The local application of combined IGF-I and TGF-beta1 had the most stimulating effect on fracture healing, followed by the effect of BMP-2, IGF-I, and TGF-beta1 alone. Bioactive coating of biomechanical well-established implants can on the one hand stabilize the fracture and on the other hand stimulate healing processes to increase healing and to reduce the rate of complications.

Biography Historical ArticleOutstanding scientist of the year 2006: Rogel Patawaran, BS.
Rogel Patawaran is cofounder of iQSecure Solutions, Inc., a secure web mail company, which began in 2002 and is currently based in Santa Monica, California. Its unique service enables hospitals, clinics, and doctors' offices the opportunity to have secure web-based video and telephone conferencing by simply switching online services offered by this innovative company. In addition, he is cofounder of AuthoTecq, based in Long Beach, California, and inventor of the AuthoTecq system in 1999. ⋯ These remarkable accomplishments in patient safety are accomplished at a rapid speed that ensures that data-sensitive patient files can be securely transmitted between and within hospitals. Finally, with the growing need for an electronic system within the medical field, doctors will be able to securely access all such data from anywhere and at any time, thus reducing the age-old problem of time constraints that a paper system presented doctors and hospitals alike. In recognition of Rogel Patawaran's contributions to the medical field through the use of encryption teamed with the transferring of sensitive data such as hospital records, Rogel Patawaran has been selected as the Outstanding Scientist of 2006.

A revolutionary advance in skin closure compared to current methods.
Six pigs were used to evaluate the influence of three separate modalities on contaminated wounds. Full-thickness skin wounds on the abdomen were contaminated with 10(4) or 10(5) Staphylococcus aureus and then closed with one of three methods. The three closure modalities included (1) a new absorbable staple (Insorb) placed in the subcuticular tissue, (2) a braided Vicryl suture, and (3) percutaneous metal staples. ⋯ Compared to metal staples, the Insorb subcuticular staplers demonstrated comparable closure time without the need for later staple removal. In conclusion, the closure of contaminated wounds with the Insorb staples is a superior choice to Vicryl suture because they have a significantly (p = 0.009) lower incidence of infection. The Insorb staple is a revolutionary advance in subcuticular skin stapling.
