It is normal practice for patients in intensive care units to be turned regularly--every two hours, or more, depending on their medical condition and at-risk status. Manual turning makes high demands on nursing time and can result in a high incidence of back injuries. The introduction of kinetic therapy as a means of keeping patients moving is proving beneficial in both intensive care and high-dependency care settings to patients and their carers. It is a therapy that can be initiated by both nursing and medical staff.

Regeneration of peri-implant infrabony defects using PerioGlas: a pilot study in rabbits.

PerioGlas is a silicate-based synthetic bone augmentation material that has been used to fill periodontal defects with bonding and integration to both soft tissue and bone. The purpose of this research was to determine the PerioGlas interface with titanium dental implants and bone. Seven live rabbits were used; however, one rabbit was euthanized at 3 days as a result of a tibial fracture through the implant placement site. Each rabbit received four 3.3 x 8 mm Imtec titanium plasma-sprayed dental implants, two in each proximal tibia. One implant in each rabbit was placed in the standard fashion. Two implants in each rabbit had a surgically created defect adjacent to one side of the coronal aspect of the implant. The defect was subsequently filled with PerioGlas. One implant in each rabbit had a surgically created defect that was not filled with PerioGlas. The rabbits were sacrificed at 1, 2, 3, 6, 12, and 24 weeks. Each specimen was prepared for histologic viewing, yielding a nondecalcified specimen demonstrating the interface of bone, implant, and PerioGlas. The results demonstrate peripheral formation of osteoid, followed by bone deposition within the defect from host (surgical margin) bone, toward the implant. The new osteoid and bone form around the PerioGlas particles. Newly formed trabeculae connect these areas of osteoid and new bone around the PerioGlas, interconnecting the PerioGlas particles. The new bone eventually reaches the implant, and osseointegration occurs with incorporation of the PerioGlas particles.

Shear bond strength of immediately repaired light-cured composite resin restorations.

The goal of this study was to examine the extent to which the state of the surface of newly placed restorations made of one of two commercial formulations of composite resin (Pertac-Hybrid and Z-100) affects the interfacial bond strength when such restorations are immediately repaired with the same resin. Three groups of specimens for each material were prepared: one group in which there was an air-inhibited film on the surface of the initial layer of the restoration, another in which that film was prevented from being formed, and a third in which that surface was abraded prior to placement of the repair layer. All specimens were stored for 6 weeks in water at 23 degrees C before being loaded to fracture in shear at a rate of 5 mm/min. The shear bond strength results were treated using the three-parameter Weibull equation and a clearly defined index of performance (I), which is a measure of both the magnitude and variability of the shear bond strength. It was found that, for two states of the surface of the initial layer, I for Pertac-Hybrid specimens is about the same as that for Z-100 specimens. For specimens made of either material, there was a demonstrable difference in I between specimens with or without an air-inhibited film on the initial layer, while abrading the surface of that layer severely degraded I.
