Suture materials and other factors associated with tissue reactivity, infection, and wound dehiscence among plastic surgery outpatients.
The most common complications in plastic surgery are tissue reactivity, infections, and wound dehiscence. In the literature, there are only a few studies with sample sizes large enough and methods of statistical analysis appropriate for evaluating the role of suture materials in inducing such complications. In the 1000 plastic surgery outpatients in this study, the association of different suture materials, individual patient characteristics, surgeon skill, and wound site and length with postoperative wound complications (i.e., tissue reactivity, infection rate, and wound dehiscence) were investigated. ⋯ Wound length was associated with the risk of tissue reactivity in one-layer sutures (OR, 2.92; 95 percent CI, 1.51 to 5.65). An increased risk of both tissue reactivity (OR, 1.53; 95 percent CI, 1.03 to 2.27) and dehiscence (OR, 2.44; 95 percent CI, 1.1 to 5.43) was observed for operations performed by less-experienced surgeons. Rather than factors related to suture materials and different surgical techniques, and with the exception of surgeon experience, general characteristics of the patients (i.e., sex and age) and of the wounds (i.e., length and site) seemed to be primarily responsible for local wound complications.

Interposition of a pedicle fat flap significantly improves specificity of reinnervation and motor recovery after repair of transected nerves in adjacency in rats.
Despite highest standards in nerve repair, functional recovery following nerve transection still remains unsatisfactory. Nonspecific reinnervation of target organs caused by misdirected axonal growth at the repair site is regarded as one reason for a poor functional outcome. This study was conducted to establish a method for preventing aberrant reinnervation between transected and repaired nerves in adjacency. ⋯ These findings were confirmed by a significantly lower rate of misdirected axonal growth as compared with groups A and B using sequential retrograde double labeling technique of the soleus motoneuron pool. We conclude that a pedicle fat flap significantly prevents aberrant reinnervation between repaired adjacent nerves resulting in significantly improved motor recovery in rats. Clinically, this is of importance for brachial plexus, sciatic nerve, and facial nerve repair.

Influence of restraining devices on patterns of pediatric facial trauma in motor vehicle collisions.
In the Commonwealth of Pennsylvania, it is required that all children under the age of 4 years be restrained by an infant seat or car seat appropriate for their age and weight. Furthermore, all individuals riding in the front seat must be restrained by a seatbelt. This study examined the relationship between patterns of facial injuries and the use of restraining devices in the pediatric population. ⋯ Of children with facial fractures, 70 percent of those 5 to 12 years old and 90 percent of those 13 to 15 years old were unrestrained (p = 0.166). In conclusion, despite legislation mandating the use of restraints, a large proportion of children involved in motor vehicle collisions were unrestrained. Furthermore, there seems to be a direct relationship between the age of a child and the incidence of facial fractures sustained in motor vehicle collisions.
