International Spinal Cord Injury Data Sets.

STUDY DESIGN: Discussion and development of final consensus. OBJECTIVE: Present the background, purpose, and process for the International Spinal Cord Injury (SCI) Data Sets development. SETTING: International. METHODS: An international meeting on SCI data collection and analysis occurred at a workshop on May 2, 2002, before the combined meeting of the American Spinal Injury Association (ASIA) and the International Spinal Cord Society (ISCoS) in Vancouver, British Columbia, Canada. At this meeting, a process was developed for selection of data elements to be included in International SCI Data Sets. RESULTS: An overall structure and terminology has been developed following the format of the International Classification of Functioning, Disability and Health (ICF). This includes definitions of the Core Data Set, as well as Modules with Basic Questions or Data Sets and Expanded Data Sets. The Core Data Set has been developed and will be presented separately. Working groups for additional modules are being established as well as general guidelines for the development of the modules. CONCLUSION: The presented format should help in developing data sets and modules within various topics related to SCI.

International Spinal Cord Injury Core Data Set.

STUDY DESIGN: Survey of expert opinion, feedback, and development of final consensus. OBJECTIVE: Present the background, purpose, development process, and results for the International Spinal Cord Injury (SCI) Core Data Set. SETTING: International. METHODS: A committee of experts was established to select and define data elements to be included in an International SCI Core Data Set. A draft core data set was developed and disseminated to appropriate organisations for comment. All suggested revisions were considered, and a final version of the core data set was disseminated again for approval and adoption. RESULTS: The core data set consists of 24 variables, including basic demographic characteristics, dates of admission and discharge from initial acute and rehabilitation care, cause of injury, place of discharge, presence of vertebral fractures and associated injuries, occurrence of spinal surgery, and measures of neurological and ventilator status. CONCLUSION: Collection of the core data set should be a basic ingredient of all future studies of SCI to facilitate accurate description of patient populations and comparison of results across published studies from around the world.

Pain classification following spinal cord injury: the utility of verbal descriptors.

OBJECTIVES: To determine the predictive utility of verbal descriptors to distinguish between pain types following spinal cord injury (SCI). DESIGN: Cross-sectional. SETTING: USA. METHODS: Participants (n=29) completed the Short Form - McGill Pain Questionnaire (SF-MPQ) for each pain site reported. A total of 64 pain sites were reported with 80% of the sample reporting multiple pain sites. Each pain site was categorized using three different SCI pain classification schemes. The predictive utility of verbal descriptors to distinguish between pain types was examined statistically using (1) each word separately, (2) a combination of words (ie, the SF-MPQ total subscales, the number of words chosen on each scale), and (3) discriminant function analysis. RESULTS: There was a substantial overlap in the use of verbal descriptors across pain types. Few differences across pain types were found for endorsement of individual words, and differences across pain types were not found for any of the word combination scores. The majority of the verbal descriptors did not enter the step-wise discriminant functions for each SCI pain classification scheme, however, 'tingling' and 'aching' showed modest predictive utility for neuropathic and musculoskeletal pain, respectively. Correct classification was in the low range (ie, 39% to 82%, average=60%, with a 33% chance level). All three pain classification schemes showed the same general pattern of results. CONCLUSION: In general, verbal descriptors alone offered marginal utility with regard to identifying specific pain types following SCI. Future directions alone and implications are discussed.

A region of adenylyl cyclase 2 critical for regulation by G protein beta gamma subunits.

Receptor-mediated activation of heterotrimeric guanine nucleotide-binding proteins (G proteins) results in the dissociation of alpha from beta gamma subunits, thereby allowing both to regulate effectors. Little is known about the regions of effectors required for recognition of G beta gamma. A peptide encoding residues 956 to 982 of adenylyl cyclase 2 specifically blocked G beta gamma stimulation of adenylyl cyclase 2, phospholipase C-beta 3, potassium channels, and beta-adrenergic receptor kinase as well as inhibition of calmodulin-stimulated adenylyl cyclases, but had no effect on interactions between G beta gamma and G alpha o. Substitutions in this peptide identified a functionally important motif, Gln-X-X-Glu-Arg, that is also conserved in regions of potassium channels and beta-adrenergic receptor kinases that participate in G beta gamma interactions. Thus, the region defined by residues 956 to 982 of adenylyl cyclase 2 may contain determinants important for receiving signals from G beta gamma.

Urological long-term follow-up in women with spinal cord injuries.

One hundred eight women and 434 men admitted with spinal cord injuries between 1973 and 1987 were observed prospectively to determine the effects of age, sex, neurological classification, and method of bladder management method on renal function and urological complications. The primary method of bladder management for women throughout the study period was indwelling urethral catheterization as compared to condom drainage for their male counterparts. Renal function was determined by effective renal plasma flow and urological complications were determined by clinical symptoms and/or objective findings on intravenous pyelography (IVP). Analysis reveals that as in the general population advancing age and being female were significantly associated with lower ERPF (p < .05). Only in men were neurological classification (quadriplegia) and bladder management (ileoconduit) associated with significant decreases in ERPF (p < .05). Furthermore, women and men showed no significant differences in urological complication rates. From the data it can be concluded that there is no particular method of bladder management for women that necessarily leads to impaired renal function.
