The impact of stenosis and translation on spinal cord injuries in traumatic cervical facet dislocations.

Background Context: Although facet dislocations account for only 6% of cervical trauma, the consequences are often devastating. Cervical facet dislocations are associated with a disproportionate amount of spinal cord injuries; however, neurologic examination of patients is often difficult, as patients commonly present with reduced levels of consciousness. There are limited studies that have investigated the impact of spinal canal diameter and translation on neurologic injury following facet dislocations.

Simple steps to minimize spine infections in adolescent idiopathic scoliosis.

Background: To examine the surgical site infection (SSI) rates in patients undergoing posterior spinal fusion surgery for adolescent idiopathic scoliosis (AIS) after implementation of a change in antibiotic prophylaxis and intraoperative irrigation.

Methods: A retrospective review of all consecutive spinal fusions for AIS from 1996 to 2008 was performed. In 2003, 2 changes in our protocol were implemented: (1) routine antibiotic prophylaxis was changed from cefazolin alone to vancomycin and ceftazidime; (2) intraoperative irrigation technique was changed from bulb syringe to pulse lavage irrigation.

Formula-fed and breast-fed baboons: Weight growth from birth to adulthood.

The objective of this study was to compare the immediate and long-term effects of type of infant diet (formula-fed vs. breast-fed) on the weight growth of baboons. Longitudinal (serial) weight data were collected from 44 savannah baboons (Papio cynocephalus anubis) for the total preadult period of growth from birth to approximately 8 years of age.

Positional and activity behavior in a captive slow loris: A quantitative assessment.

This study examines the positional and activity behavior of a captive slow loris, Nycticebus coucang. The male individual was housed in a primate facility providing a seminatural environment and was subjected to a series of videotape recordings from which 1,878 point observations were taken. The enclosure was designed to allow maximum flexibility of substrate use.

Growth and development in the saddle-back tamarin: The sequence and timing of dental eruption and epiphyseal union.

A cross-sectional sample of 121 colony-born saddle-back tamarins, Saguinus fuscicollis, was examined to identify the sequence and timing of dental eruption and epiphyseal union. The state of dental development of the deciduous and permanent dentitions was recorded as erupted or non-erupted on the basis of gingival penetration. Eighteen areas of union of long bone epiphyseal and other secondary centers, the union of the primary elements of the innominate, and the spheno-occipital synchondrosis were examined.
