Concerns about drug-resistant infectious organisms are increasing in rehabilitation facilities. Resulting isolation protocols can potentially challenge the patients' access to medical care, psychological adaptation, mobility, and environmental interaction and therefore hinder the rehabilitation process. We report a systematic, retrospective case review of an active-duty Army sergeant who sustained a C5 American Spinal Cord Injury Association Impairment Scale A spinal cord injury while serving in Operation Iraqi Freedom. The patient's acute rehabilitation was complicated by an Acinetobacter calcoaceticus-baumannii complex infection, in the blood and urine, contracted while in Iraq. Isolation protocols were designed to enable regular hands-on contact for proprioceptive neuromuscular facilitation, transfers, wheelchair fitting, mobility training, and environmental control. After 1 mo of comprehensive acute interdisciplinary rehabilitation, delivered in a single room on the spinal cord injury unit, the patient acquired functional skills comparable with other complete C5 tetraplegics in our unit. If a patient with spinal cord injury must be placed in isolation, it is still feasible to conduct a comprehensive interdisciplinary rehabilitation program while strictly adhering to contact isolation protocols.
Enhancing the technology of bone-anchored limb prosthetics, we present a modified porcine model for developing an infection-free integration between the skin and a percutaneous bone implant. The deeply porous Skin and Bone Integrated Pylon (SBIP) presented an infection-free skin-implant interface both after implantation into the dorsum and after implantation into the residuum after below-knee amputation. However, deep ingrowth of skin into the porous cladding of the SBIP was achieved better in the dorsal procedure, while implantation to the residuum sometimes developed a stoma, probably due to the high mobility of the skin and soft tissues in the pig's thigh. Uncontrolled high skin mobility during the first week after implantation constituted a limitation for the porcine animal model, which we tried to address in the current study. As our previous studies showed that casting of the leg residuum did not sufficiently limit the skin's movement around the implant, we tested a modified protocol of the implantation, which included injection of botulinum toxin into the thigh muscles. During the course of the study, we identified proper botulinum toxin componentry, dosage, and the period after injections to achieve a maximal effect of immobilization of the muscles affecting skin movements. To verify the immobilization, we used kinetic data on the asymmetry of loading during gait with the Strideway System, Tekscan, Inc., Boston, MA, USA. We found that injections in the four muscles of the distal thigh of the left hind leg with MYOBLOC® (rimabotulinumtoxinB; 5,000 units/muscle) were sufficient to provide noticeable immobilization by the fourth week after the procedure. This conclusion was made based on the analysis of the dynamics of asymmetry in vertical ground reactions on the injected (left hind) and uninvolved (right hind) legs during gait over an instrumented walkway.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
