Chronological versus skeletal age, an evaluation of craniofacial growth.

Skeletal and chronologic ages of both female and male populations were compared relative to the degree of concurrence between the two age-indices at the various age levels. Maxillary and mandibular cephalometric measurements were similarly compared for both sex groups. Individual's comparisons of facial changes were made relative to their respective chronologic and skeletal ages. The significance of a skeletal vs. chronologic age discrepancy and its relationship to the timing of facial growth was demonstrated. Clinical implications were discussed.

Scintigraphic detection of congenital intracranial vascular malformations.

Nine children with arteriovenous malformations (AVMs), and a tenth with a cerebral aneurysm, had computer-processed dynamic scintigraphy with static scintigrams, transmission computed tomography (CT) both with and without contrast injection, and radiopaque cerebral angiography. All ten lesions were detected by dynamic scintigraphy and angiography, whereas two AVMs were missed on CT scans and the aneurysm and two AVMs (one missed by CT) were not identified on static scintigrams. Time-activity curves generated from regions of interest placed over the cerebral hemispheres, AVMs and/or various venous structures permitted, respectively, estimation of interhemispheric partition of perfusion, estimation of the fraction of total cerebral hemispheric perfusion preferentially directed into a malformation, and indication of the route of venous drainage from the lesions. While dynamic scintigraphy and CT scanning both identified the aneurysm, scintigraphy was the most effective screening test for detecting AVMs owing to its accuracy, lower cost, and lack of required anesthesia, heavy sedation or iodinated contrast agents.

Acute infantile motor unit disorder. Infantile botulism?

Eight infants with an acute reversible motor unit disorder are described, including two infants from whom Clostridum botulinum type A was isolated from stool specimens. The clinical spectrum includes constipation, cranial nerve deficits, pupillary involvement, and generalized hypotonic weakness. There were no deaths, and all infants have had complete clinical recovery. A characteristic electromyographic (EMG) pattern was present in part until clinical recovery. This distinctive pattern consisted of brief, small, abundant for power exerted motor unit potentials. This EMG pattern in the context of the clinical syndrome may well be diagnostic for acute infantile motor unit disorder.

Dental and skeletal relationships to attritional occlusion.

Dental attrition has been investigated in depth. Besides alterations in arch length due to attrition, skeletal and intra-arch differences were discovered. It is felt that these findings do have value in helping us realize that present-day concepts of proper occlusion cannot necessarily be applied to dentitions that existed at another time. A more thorough knowledge of occlusions exhibiting dental attrition provides information that is helpful in understanding more fully the nature of tooth eruption and associated dental arch occlusion and the interrelationships of these factors with supporting skeletal structures.
