Abstract
Outcomes research in pediatric liver transplant (LT) has focused on mortality and morbidity but there is a need to also evaluate functional outcomes. Standardized cognitive testing was administered to a cohort of children with infantile chronic liver disease who were transplanted at the University of Alberta during their preschool years. Thirty children had comprehensive assessments with the Bayley Scales of Infant Development or Wechsler testing. Patient variables potentially associated with cognitive delay were analyzed with multiple regression analysis. The mean DQ/IQ score (developmental quotient/intelligence quotient) was 81 +/- 17. Delay (DQ/IQ score < 70), and borderline delay (DQ/IQ 70-84) were each present in 27% of the cohort, with only 46% demonstrating normal cognition. Regression analysis demonstrated that the decreased IQ was associated with pretransplant growth retardation and elevated calcineurin inhibitor levels. Performance IQ had strong correlation with pretransplant growth retardation and elevated serum ammonia, R(2)= 45%, compared to verbal IQ that was associated was elevated calcineurin inhibitor levels, R(2)= 23%. Children post-LT are at high risk for cognitive delay or borderline delay. This is the first study to demonstrate the association calcineurin inhibitors with impaired IQ and also the unique finding of different variables predictive of impaired verbal intelligence quotient (VIQ) versus performance intelligence quotient (PIQ).

Abstract
PURPOSE The satisfaction of families of adolescents and young adults with a diagnosis of cerebral palsy with the service delivery they had experienced in the areas of health, education, recreation, employment, housing and transportation was examined. Common themes across the six service areas were identified. METHOD Forty-nine adolescents (13-15 years) and 39 young adults (19-23 years) and their families rated their satisfaction with services and then participated in semi-structured interviews to discuss their experiences. RESULTS Using a constant comparative method of analysis, common themes were identified from the transcribed interviews. Four themes were identified and named: caring and supportive people; fighting and fatigue; communication/information; and disability awareness. CONCLUSIONS Families continue to experience dissatisfaction and frustration with service delivery in the six areas examined. Both bureaucratic structure and attitudes of service providers contribute to their dissatisfaction.

Abstract
This study compared adolescents with cerebral palsy (CP) and their families to adolescents without physical disabilities and their families as the child enters and leaves adolescence (age ranges 13 to 15 years and 19 to 23 years). Families of 90 individuals with CP (42 females, 48 males) and 75 individuals without physical disabilities (34 females, 41 males) participated. They completed the Family Assessment Device, Life Situation Survey, Multidimensional Scale of Perceived Social Support, and Future Questionnaire. There were few differences in family functioning, life satisfaction, or perceived social support between the groups. Expectations of young adults with CP and parents of both adolescents and young adults regarding future independence and success were lower than the expectations of the control group. While the group results emphasize similarities between families during the two stages of adolescence, individual families and individual family members report specific challenges.

Abstract
Higher level relationships among placental mammals, as well as the historical biogeography and morphological diversification of this group, remain unclear. Here we analyse independent molecular data sets, having aligned lengths of DNA of 5,708 and 2,947 base pairs, respectively, for all orders of placental mammals. Phylogenetic analyses resolve placental orders into four groups: Xenarthra, Afrotheria, Laurasiatheria, and Euarchonta plus Glires. The first three groups are consistently monophyletic with different methods of analysis. Euarchonta plus Glires is monophyletic or paraphyletic depending on the phylogenetic method. A unique nine-base-pair deletion in exon 11 of the BRCA1 gene provides additional support for the monophyly of Afrotheria, which includes proboscideans, sirenians, hyracoids, tubulidentates, macroscelideans, chrysochlorids and tenrecids. Laurasiatheria contains cetartiodactyls, perissodactyls, carnivores, pangolins, bats and eulipotyphlan insectivores. Parallel adaptive radiations have occurred within Laurasiatheria and Afrotheria. In each group, there are aquatic, ungulate and insectivore-like forms.

Abstract
Patient management in the current health care environment requires the provider to make reliable and valid clinical decisions regarding patient care, decisions that are cost effective and will lead to optimal functional improvement. Neurologic examination, according to the Standards for Neurological and Functional Classification of Spinal Injury developed by the American Spinal Injury Association, provides every clinician with simple clinical tools that are highly predictive of functional recovery following a spinal cord injury. The ability to predict motor recovery provides a rational basis to help support the provider's recommendation for the patient's goals and care planning, as well as differentiates care that is essential for improving functional outcomes from care that is not.

Abstract
PURPOSE We attempted to determine whether an introducer tip catheter reduces urinary tract infection in spinal cord injured patients on intermittent catheterization. MATERIALS AND METHODS The introducer tip catheter bypasses the colonized 1.5 cm. of the distal urethra. Enrolled patients were prospectively entered into the study in alternate groups depending on whether they reflex voided: group 1--on intermittent catheterization with the introducer tip catheter but not voiding spontaneously or wearing an external urinary catheter, group 2--same as group 1 but using a nonintroducer tip catheter; group 3--on intermittent catheterization with the introducer tip catheter, voiding by reflex and wearing an external urinary catheter, and group 4--same as group 3 but using a nonintroducer tip catheter. RESULTS Statistical significance was shown when comparing patients using versus not using the introducer tip catheter regardless of whether an external urinary catheter was worn (p = 0.0121). A greater difference was noted between patients using and not using the introducer tip catheter in the intermittent catheterization only group (p = 0.0093). CONCLUSIONS The introducer tip catheter decreased urinary tract infections in hospitalized men with spinal cord injury on intermittent catheterization.

Abstract
Quantitative cultures of the urethral meatus were obtained from women with SCI undergoing intermittent catheterization. When compared with the urethral cultures of a group of female subjects, women with SCI had a greater number of isolates of Klebsiella pneumonia and Pseudomonas aeruginosa in the urethral flora. However there was not a significantly greater number of isolates or log numbers of E. coli or Enterococcus sp. in the urethral flora. The E. coli and Enterococcus sp. isolated from the urine were not isolated from the urethra of female patients with SCI in one third of the patients. This poor correlation between the simultaneous urethral and urine cultures of female subjects with SCI may reflect colonization of the urine with organisms that were unable to adhere to the mucosa and colonize the urethra. To what extent these organisms colonize or are temporary residents may be important in the pathogenicity of the infection.

Abstract
Twenty-two people with no extremity disability were tested in a standard fashion using the Jamar Dynamometer to establish their maximum grip strength. Each participant was asked to grip first right-handed then left-handed three consecutive times. The directions were reexplained so that each participant would give a consistent, less than optimal effort; three trials right and three trials left were recorded. The standard deviations of each set of these trials were calculated for both right and left hands. These standard deviations were then tabulated as scores for 44 trials of 22 patients, both hands, for maximal and submaximal efforts. These scores were then compared, maximal versus submaximal, using a paired t-test. We found no statistical difference in the two groups in comparing the variability of results. Therefore, the current protocol for Jamar testing can allow a patient to make a consistently submaximal effort, resulting in a false apparent loss of grip strength.

Abstract
Assessment of strength using motor scores derived from the standards of the American Spinal Injury Association (ASIA) was compared with assessment using motor scores based on biomechanical aspects of walking in the prediction of ambulatory performance. Measurements of strength, gait performance, and the energy expenditure were performed in 36 spinal cord injured patients. The ASIA scoring system compared favorably with the biomechanical scoring system. The ASIA score strongly correlated with the percent increase in the rate of O2 consumption above normal (p < .0005), O2 cost per meter (p < .0006), peak axial load exerted by the arms on crutches (p < .0001), velocity (p < .0001), and cadence (p < .0001). Patients with lower extremity ASIA scores < or = 20 were limited ambulators with slower average velocities at higher heart rates, greater energy expenditure, and greater peak axial load exerted on assistive devices than patients with lower extremity ASIA scores > or = 30 who were community ambulators. We conclude the ASIA motor score is a simple clinical measure that strongly correlates with walking ability.

Abstract
Motor and sensory recovery were determined in five patients with ischemic myelopathy associated with traumatic laceration or surgical manipulation of the thoracic aorta. The neurologic level of injury was between T-2 and T-10. All patients had an anterior spinal artery pattern of incomplete spinal cord injury consisting of relatively greater loss of motor function than sensation and preservation of sacral sensation. None of the three patients with zero lower extremity motor function at 30 regained any motor function at 1 year. Two patients with partial motor function 1 month after infarction had further motor recovery at 1 year. One of these two individuals was able to ambulate independently with a reciprocal gait using orthoses.

Abstract
We performed a retrospective review of the medical records of 316 patients with spinal cord injury (SCI) secondary to gunshot wounds (GSW) admitted to Rancho Los Amigos Medical Center for rehabilitation between 1980 and 1988. There were 289 male and 27 female patients whose mean age was 25.9 years (range, 11-56 years). Of these, 238 were paraplegic (103 incomplete, 135 complete), and 78 were quadriplegic (45 incomplete, 33 complete). Forty were shot by handguns of known caliber and four by shotguns; in 272 cases, the type of weapon was unknown. A total of 230 cases sustained a single bullet wound, and 86 had multiple bullet wounds. The length of acute hospitalization, but not rehabilitation hospital stay, increased with the number of associated injuries. Rehabilitation and, hence, total length of stay was significantly less (mean, 100 and 130 days, respectively) for SCI/GSW victims than for SCI victims of motor vehicle accidents, falls, or diving accidents. The methods of calculating costs for admission were based upon Rancho Los Amigos Medical Center financial statistics. This hospital has charged for a daily occupancy fee. The fee is based upon an average of all charges for all patients. No additional fees are charged for special tests or procedures. In 1980, the average daily admission hospitalization charge was $785. In 1990, the last quoted hospital charge was $1,125. This is for the basic spinal cord injury rehabilitative stay. In general, at Rancho Los Amigos, patients are admitted for rehabilitation when all acute medical and surgical problems have been cleared and the patient is ready to participate in rehabilitation evaluation and therapy programs.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Dual-photon absorptiometry (DPA) is now widely used to determine bone mineral density of the lumbar spine and hips. Because the resulting images are often not of sufficient resolution to identify many bone or soft tissue abnormalities that may influence results, clinical and radiographic correlation is necessary. Presented are two cases in which results of DPA of the hips were elevated because of the presence of heterotopic ossification.

Abstract
Measurement of lower extremity muscle strength and the energy expenditure during walking was taken in 36 spinal cord injury patients to assess functional mobility. Patients were categorized according to the type of orthotic prescription (knee-ankle-foot orthosis [KAFO] or ankle-foot orthosis [AFO]) or upper extremity assistive device (cane, crutches, or walker) used during gait. The rates of O2 consumption per minute, O2 cost per meter, heart rate, respiratory quotient, velocity, cadence, and peak axial load exerted by the arms on upper extremity assistive devices were measured. The Ambulatory Motor Index (AMI), derived from the manual muscle grades of both lower limbs, was used as the indicator of the degree of paralysis. The AMI was strongly correlated with the percentage increase in the rate of O2 consumption above normal (p less than .0001), O2 cost per meter (p less than .0001), peak axial load (p less than .0001), velocity (p less than .0001), and cadence (p less than .0001). Differences in these parameters among patient groups categorized according to the type of orthotic prescription (no KAFO, one KAFO, two KAFOs) or upper extremity assistive device (no device, cane or one crutch, two crutches, or walker) were attributable to differences in the AMI. The AMI, therefore, could be used as a reliable clinical indicator of functional mobility after spinal cord injury.

Abstract
Thirty-eight (49 per cent) of seventy-seven paraplegic patients whose level of injury was at or caudad to the second thoracic vertebra were found to have signs and symptoms of carpal tunnel syndrome. The prevalence of carpal tunnel syndrome was found to increase with the length of time after the injury. In the eighteen patients in whom manometric studies were done, the carpal tunnel pressures when the wrist was in the neutral position were higher than those that have been reported in non-paraplegic patients who did not have carpal tunnel syndrome but were lower than the values in non-paraplegic patients who did have the syndrome. When the wrist was in flexion, the pressures were similar to the values that have been reported for non-paraplegic patients. However, in the paraplegic patients, regardless of whether or not they had carpal tunnel syndrome, the pressures that developed when the wrist was in extension were significantly higher than those in non-paraplegic patients, regardless of whether or not they had carpal tunnel syndrome. Most of the activities of daily living of paraplegic patients, including the maneuver to relieve ischial pressure that consists of arising from the seated position using the extended arms, are performed with the wrists locked in maximum extension. The pressure that develops in the carpal canal during this forced extension of the wrist, probably combined with the repetitive trauma to the volar aspect of the extended wrist while propelling a wheelchair, contributes to the high frequency with which carpal tunnel syndrome is found in paraplegic patients.
