A 12-year-old girl had chronic nonspherocytic hemolytic anemia due to triosephosphate isomerase deficiency. Developmental and motor delay and muscular weakness were followed by cerebellar dysfunction and finally spasticity with hyperreflexia. Abnormal histopathological findings were hyaline cell bodies and axonal "spheroids" in the hypothalamus and(More)
The orbicularis oculi reflex and direct facial nerve conduction were studied in 38 normal children ranging in age from 1 month to 9 years. Direct facial nerve conduction in all groups was within adult normal values. The early response of the orbicularis oculi reflex obtains normal adult values by age 24 months. Both ipsilateral and contralateral delayed(More)
Feedback loops involving soil microorganisms can regulate plant populations. Here, we hypothesize that microorganisms are most likely to play a role in plant–soil feedback loops when they possess an affinity for a particular plant and the capacity to consistently affect the growth of that plant for good or ill. We characterized microbial communities using(More)
The orbicularis oculi reflex was studied in 12 children with intrinsic brain stem gliomas and in six children with other posterior fossa pathology. The results were compared with previously established childhood normal values. Seventy-eight percent of the children demonstrated a pathologic alteration of the reflex comparable to reported results in adult(More)
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(More)
