The most important effects of hyperbaric oxygen (HBO), for the surgeon, are the stimulation of leukocyte microbial killing, the enhancement of fibroblast replication, and increased collagen formation and neovascularization of ischemic tissue. Preoperative hyperbaric oxygen induces neovascularization in tissue with radionecrosis. Refractory osteomyelitis and(More)
BACKGROUND Data about the frequency of adverse events related to inappropriate care in hospitals come from studies of medical records as if they represented a true record of adverse events. In a prospective, observational design we analysed discussion of adverse events during the care of all patients admitted to three units of a large, urban teaching(More)
We describe a modified technique for the salvage of a total knee arthroplasty after disruption of the extensor mechanism. Between January and December 1992, seven patients had reconstruction of the extensor mechanism with use of a medial or an extended medial gastrocnemius flap. Six of the seven patients were followed for a mean of thirty-three months(More)
The material properties of ten 2-O suture materials were evaluated tensiometrically at time = 0 and again after 6 weeks incubation in rats. All suture material was incubated and tested without knots. Specialized machinery was used with a custom securing apparatus to pull suture material apart at constant speed. Stress-strain curves were derived, and from(More)
BACKGROUND Toxic epidermal necrolysis syndrome is a devastating disease, with mortality rates ranging between 20 and 60 percent. This study evaluated an alternative treatment approach using antishear wound care and compared outcomes using the severity of illness score for toxic epidermal necrolysis syndrome (SCORTEN) system. METHODS Records of 48 patients(More)
Frostbite injuries have traditionally been treated with expectant observation. With the exception of early blister aspiration tissues are allowed to demarcate before definitive debridement is accomplished. Triple-phase bone scanning has been used to define the extent of fatally damaged tissues in an attempt to allow for early debridement and wound closure.(More)
OBJECTIVE Two methods of subatmospheric pressure wound therapy--wall suction applied to a sealed gauze dressing (GSUC) and the vacuum-assisted closure device (VAC)--were compared in hospitalized patients at University of Chicago Medical Center. SUMMARY OF BACKGROUND DATA VAC therapy is widely used, but can be expensive and difficult to apply; it also(More)
The source and depth relationships of both isolated burns to the feet and pedal burns as part of multifocal thermal trauma are evaluated. Five years of cases at the University of Chicago Burn Center were selected at random and retrospectively reviewed. There were 33 isolated burns of the foot, with a source distribution of 70% scald, 9% grease, 9% hot(More)
Human capacity for physiologic adaptation to cold is minimal; we survive by insulating ourselves with protective clothing. In addition to the irreversible direct injury caused by ice crystallization, the authors have outlined four possible mechanisms by which indirect injury may damage tissue. Other than rapid rewarming, there is no uniformly accepted(More)
Traumatic amputation of the lip is a rare yet devastating event affecting both form and function. Considering the available methods for reconstruction, replantation may offer a reasonable solution. We sought to characterize the variables associated with lip replantation and to assess the outcome in a retrospective review of 13 lip replantations performed in(More)
