Spinal cord infarction due to minor trauma in children.

In two children, ages 22 months and 4 years, after slight trauma, flaccid weakness of both arms developed, followed by flaccid quadriplegia with sphincter involvement. No vertebral fracture or dislocation was found, myelograms were negative, and diagnosis was made only after the full clinical syndrome developed. Pathologic studies revealed ischemic infarction involving the cervical cord and low medulla in one patient, and central gray matter of low cervical cord in the other, without hematomyelia or external compressive lesions. The pattern of infarction may be related to spasm of distal branches of the central sulcal arteries in a terminal arterial bed.

Adverse events following immunization: assessing probability of causation.

The Monitoring System for Adverse Events Following Immunization of the Centers for Disease Control collects data on events temporally related to immunization. Occasionally, reports are received of neurologic disturbances temporally related to receipt of vaccine. Most of these disturbances are events that regularly occur in the absence of immunization. It is then difficult to determine whether the relationship between the immunization and illness is causal or coincidental. We developed a method to assess causation of serious neurologic events by probability theory. By combining epidemiologic information on disease incidence with specific elements of the patient history, an estimate of the odds of vaccine causation can be derived, based on rational assumptions rather than observer bias. The result is not a diagnosis but an estimate of probability.
