Cervical sagittal spinal canal size in spine injury.

This study investigated the relationship between cervical spine sagittal canal diameter and neurologic injury in cases of spinal fracture-dislocation. A group of 98 patients with such injuries was reviewed; 45 had no neurologic deficits, 39 had incomplete quadriplegia, and 14 had complete quadriplegia. Spinal canal sagittal diameter was measured in all, and large diameter and small canals were defined. Small diameter canals were correlated significantly with neurologic injury, while large diameter canals allowed protection from neurologic injury in cervical fracture dislocation.

Craniofacial anomalies in the Upper Missouri River over a millennium: archeological and clinical evidence.

Congenital facial clefting occurs more often in Native Americans from the Upper Missouri River Basin (UMRB) than it does in the general population. However, no facial clefts were seen in 3,750 ancient UMRB skeletons. Very few reports concerning defective palate crania are in the literature of paleopathology. Findings regarding craniofacial anomalies in today's native Americans in the UMRB are presented briefly and compared to those in skeletons from this region. There is a marked difference between the frequency of anomalies which occurred in the past and those which are present today. Although the people sampled here were from many cultures and lived during different time periods, encompassing over a millenium, the fundamental denominator was a common geographic location. Reasons for the differences between the past and the present are advanced. It may be possible to estimate the frequency of anomalies which have not been found in archeological specimens but which are present today. By comparing data concerning "occult" congenital anomalies of the past with those of the present, the actual prevalence of past cranio-facial anomalies may be estimated through careful extrapolation.

Significance of pneumatosis cystoides intestinalis after jejunoileal bypass.

In 148 radiographs taken two weeks to twenty-seven months postoperatively in a series of 402 jejunoileal bypass patients at the University of Minnesota, twenty-four patients demonstrated roentgen evidence for pneumatosis intestinalis on twenty-eight separate episodes. This primarily involved the right colon. Clinical signs and symptoms were reviewed in association with the roentgen findings. Symptoms of nausea, vomiting, fever, and abdominal stress were noted but were not universal. Six patients had no significant change in abdominal complaints at the time the pneumatosis was seen and seven patients had similar clinical findings without roentgen evidence for pneumatosis. Thus, the radiographic findings of pneumatosis intestinalis do not represent a specific sign for bypass enteritis.
