Predictors of outcome following severe head trauma: follow-up data from the Traumatic Coma Data Bank

Outcome as a function of employment status or return to school was evaluated in severely head-injured patients. A priori we selected the most salient demographic, physiological, neuropsychological and psychosocial outcome predictors with the aim of identifying which of there variables captured at baseline or 6 months would best predict employability at 6 or 12 months. Based on the patients evaluated at 6 months, 18% of former workers had returned to gainful employment and 62% of former students had returned to school. For those not back to work or school at 6 months, 31% of the former workers and 66% of the former students had returned by 12 months. Age, length of coma, speed for both attending and motor movements, spatial integration, and intact vocabulary were all significantly related to returning to work or school. The three most potent predictors for returning to work or school were intactness of the patient's verbal intellectual power, speed of information processing and age.     

EEG pharmacodynamics upon single administration of seduxen in healthy volunteers

We have examined the type I collagen protein, RNA, and cDNA of 2 children with moderately severe (type IV) osteogenesis imperfecta (OI). They have in common a non-lethal form of OI with ambulatory potential, overmodification of type I collagen protein, and a substitution of serine for glycine in the collagen chain produced by one alpha 1(I) allele. The first child (Marini et al.: J Biol Chem 264:11893-11900, 1989) is now 7 years old, with the height of a 3-year-old. Her course includes significant remodeling of lower long bones and 4 femur fractures. She walks independently. A mishmatch was detected in her alpha 1(I) mRNA using RNA/RNA hybrids; it was demonstrated to be due to a G-->A point mutation in one allele of alpha 1(I), resulting in the substitution of serine for glycine 832. The second child is now 6 1/2 years old, with the height of 1 1/2-year-old. Her history includes significant bowing of femurs and tibias, 6 femur fractures, S-curve scoliosis, compression of all lumbar vertebrae, and limited short-distance walking with braces. Her alpha 1(I) mRNA has also been studied by RNA hybrid analysis; there is a single G-->A change in one alpha 1(I) allele causing the substitution of serine for gly 352. Both children have moderately severe OI. However, the serine substitution at gly 352 is associated with a more severe phenotype then is the serine substitution at gly 832. Compared to substitutions described in other cases of OI, the serine 352 is located in the middle of a cluster of cysteine substitutions associated with non-lethal OI.(ABSTRACT TRUNCATED AT 250 WORDS)     

Chapter scholarship development

The Great Lakes Chapter of the Intravenous Nurses Society developed a scholarship program to reward members for participation in INS activities and to promote the INS goals of education and knowledge sharing. Scholarships were awarded for holding office or committee work, educational activities or authorship, meeting attendance and recruitment efforts, and certification/recognition by INS. This article describes the point system used for awarding scholarships, program funding, and pitfalls in the program.     

Functional analysis of linker insertions and point mutations in the alpha-Amy2/54 GA-regulated promoter

First metatarsal fractures are rare because of their thick size and shape. They are to be treated aggressively because of the prolonged disability associated with such fractures. Any injury to the first ray may drastically alter the pattern of normal gait and weight-bearing. Most of the literature regarding such fractures is anecdotal, and there is little in the way of scientific articles that investigate their management. The general consensus for treatment of closed, nondisplaced first metatarsal fractures is to use some form of plaster immobilization. Nevertheless, there is much variation in the literature concerning the length of time patients should be casted. Rigid internal fixation using AO techniques is preferred if open reduction is to be instituted. Long-term complications with first metatarsal fractures are attributed mostly to malunion in the sagittal plane, resulting in a nonplantigrade foot.
