Evaluation of the efficacy of a bioerodible bupivacaine polymer system on antinociception and inflammatory mediator release.

Pain due to tissue injury is often characterized by the presence of hyperalgesia and allodynia. It is hypothesized that these perceptual states are mediated by sensitization of peripheral terminals of primary afferent neurons together with several changes in the central nervous system. This provides a rationale for preemptive analgesia, whereby the blockade of primary afferent input prior to injury may result in a reduction of post-injury pain.

Otodental syndrome, oculo-facio-cardio-dental (OFCD) syndrome, and lobodontia: dental disorders of interest to the pediatric radiologist.

Three unusual dental anomalies are presented which should be of interest to the pediatric radiologist: otodental syndrome - an autosomal dominant syndrome of bizarre, greatly enlarged teeth with bulbous crowns (globodontia) that spares the incisors, in combination with sensorineural hearing loss; oculo-facio-cardio-dental syndrome - an X-linked dominant syndrome that is lethal in males, characterized by congenital cataracts, unusual facies, atrial septal defect (ASD), ventricular septal defect (VSD), and canine teeth that cease to grow only when they cut off their own blood supply by growing through the orbit and lower border of mandible; and lobodontia - a dominant disorder characterized by teeth whose crowns resemble those of a wolf.
