[Investigation and analysis of acute poisoning of organic fluorine mixed gas in a fluorine polymerization plant].

In January 2021, an acute chemical poisoning incident occurred at a fluorine polymerization plant. Through the analysis of the occupational health situation of the enterprise, combined with the clinical manifestations of the poisoned patients and the laboratory examination results, it was determined that the incident was an acute poisoning incident caused by the inhalation of organic fluorine mixed gas in the fluorine polymerization plant. Subsequently, it was clarified that the accident was caused by the illegal operation of the employees of the fluorine polymerization plant, which caused the discharge of the organic fluorine mixed gas containing high concentration of octafluoroisobutene, resulting in the poisoning of the on-site construction personnel. In order to avoid the occurrence of similar incidents, enterprises should implement the main responsibility of safety production, regularly organize supervision and inspection, eliminate illegal operations, conduct safety education and training for the staff of the unit and outsourced staff, and improve the emergency rescue ability of sudden poisoning incidents.

Effectiveness of The Wikipedia Collaboration of Dental Schools' Training Programme: a new Paradigm for Teaching and Learning of Evidence-Based Dentistry.

BACKGROUND: The Wikipedia Collaboration of Dental Schools (WCODS) is a student-led initiative that aims to publish high quality scientific, evidence-based dental content on the Wikipedia online encyclopaedia by equipping its members to use research, critical appraisal and writing skills to create accurate content. In 2019, the Collaboration launched a standardised training programme developed by Wikimedia-trained committee members, academic dental school staff and the Cochrane Oral Health global community. OBJECTIVE: To evaluate the effectiveness of this training programme in ensuring WCODS editors follow the processes underpinning Evidence-Based Dentistry (EBD). METHOD: A cohort of dental students and staff (n=136) from six dental schools in the UK and Malaysia took part in a standardised and structured training programme at the annual WCODS training meeting. Participants' abilities and their perceived levels of confidence in carrying out critical analysis of the literature were measured using pre- and post-training surveys, and competency assessments. RESULTS: Participants' skills in conducting literature searches, critical appraisal of the findings and creating and editing a Wikipedia page improved after training. CONCLUSION: The training programme provided participants with the skill set and confidence to apply best practice to create and edit Wikipedia entries. This Collaboration intends to recruit more contributors to improve global oral health literacy using the free online Wikipedia encyclopaedia.

Hepatitis B virus infection among children of hepatitis B surface antigen positive mothers in a Malaysian hospital.

INTRODUCTION: There have been no published data on the transmission of hepatitis B virus (HBV) infection among children of hepatitis B surface antigen (HBsAg) positive mothers in Malaysia. METHODS: This is a cross-sectional study of all the children of HBsAg-positive mothers who delivered at the University of Malaya Medical Centre between 1993 and 2000. RESULTS: A total of 60 HBsAg-positive mothers and their 154 children participated in the study. HBsAg was detected in four children (2.6%) while IgG antibody to the hepatitis B core antigen (anti-HBc IgG) was detected in seventeen children (11.0%). The mother's age at childbirth was significantly lower in the children with detectable HBsAg (22.5±6.1 years vs. 29.7±4.5 years, p=0.043) and anti-HBc IgG (26.6±6.1 years vs. 30.0±4.3 years, p=0.004). Children born in the 1980s were significantly more likely to have detectable HBsAg (18.8% vs. 0.7%, p=0.004) and anti-HBc IgG (37.5% vs. 8.0%, p=0.000) compared with those born later. All children with detectable HBsAg were born via spontaneous vaginal delivery, and hepatitis B immunoglobulin was either not given or the administration status was unknown. The majority of mothers with chronic HBV infection (70.4%) were not under any regular follow-up for their chronic HBV infection and the main reason was the lack of awareness of the need to do so (47.4%). CONCLUSION: Transmission of HBV infection among children of HBsAg-positive mothers in Malaysia is low. However, attention needs to be given to the high rate of HBsAgpositive mothers who are not on any regular follow-up.

Traditional and Complementary Medicine (TCM) among Study Population with Cardiovascular Risk; use and Substitution for Conventional Medicine in Pahang, Malaysia.

INTRODUCTION: Cardiovascular diseases are the main cause of morbidity and mortality in Malaysia. There is evidence of high traditional and complementary medicine (TCM) use among population with cardiovascular risk and there have been anecdotal reports about substitution of conventional medicines with TCM. We investigated the prevalence of TCM use, treatment preference and substitution of conventional medicines in study population with cardiovascular risk factors in Pahang, Malaysia. METHODS: A cross-sectional survey was conducted using an interviewer-administered questionnaire in five districts of Pahang. A total of 1250 households were chosen through proportionate and systematic sampling. Respondents aged 18 years and above were selected. RESULTS: The study population with cardiovascular risk factors who used TCM was higher than the general population (31.7% versus 25.9%). There were no clear preferences in using TCM by gender, age groups, educational level and income even though other bumiputeras showed a slight inclination towards TCM use. Among the study population with cardiovascular risk factors who consumed TCM, 20-30% of them were using TCM as a substitute for their conventional medications. Respondents from the younger age group (18-40 years) (57.1%), highest educational level (43.2%), other bumiputeras (38.4%) and highest income group (31.4%) preferred the combination of both conventional and traditional medicine. CONCLUSION: TCM use among population with cardiovascular risk factors is high. The high preference for combination therapy of TCM and conventional medications among young adults and the use of TCM to substitute conventional medications show that much research is needed to provide proven TCM therapies to avoid self-mismanagement of cardiovascular risk in Malaysia.

Students' satisfaction with a dental summer programme and importance of influencing factors for choosing dentistry as their career.

AIM: To study the students' satisfaction with the week-long summer programme and the importance of common influencing factors (IFs) for choosing dentistry as their career. METHODS: Anonymous questionnaire was given to all 214 participants in July of 2011 and 2012. Demographic information including gender, age and education level was collected. The students were asked about their satisfaction with the programme with separate ratings for learning experiences, including hands-on workshops (HOW); clinic observations (CO); problem-based learning tutorials (PBL); and lectures (L). They also rated the relative importance of the ten common IFs. The Friedman test was used to study the order of their preferences of the programme's activities. The Chi-square test was used to study the influence of their demographic factors on the importance of the IFs. RESULTS: A total of 208 students returned their questionnaires. The majority were below the age of 18 (81%), and 44% were studying in an international school. Most of the students (96%) were satisfied with the programme overall. They liked the HOWs and COs more than the PBL tutorials and Ls. 'Altruism' and 'medical/health care career' were the two most important IFs overall. 'Altruism' and 'past experience with dentist' were considered more important by those aged 18 or above. 'Past experience with dentist' and 'working with hands' were considered more important by the international school students. CONCLUSIONS: Most participants were satisfied with the summer programme. They preferred practical, skill-based activities to knowledge-based activities. The importance of some IFs was associated with age and education system.

Outbreak of Occupational Brucellosis at a Pharmaceutical Factory in Southeast China.

Brucellosis is an occupational disease affecting workers in butcher shops, the milking and dairy product industry, causing more than 500 000 new cases around the world. As a national statutory B infectious disease in China, morbidity of brucellosis is rapidly increasing in recent years. We report an occupational outbreak of brucellosis infection in a pharmaceutical factory. Exposure was a result of manual operation in the process line, close contact with sheep placentas, insufficient disinfection and repeated using of protective suits and infected by aerosol dissemination. Improved preventive methods, appropriate public health measures and spread of health education would be helpful to prevent the occupational outbreak of brucellosis in future.

When the stork arrives unannounced - seven years of emergency deliveries in a non-obstetric general hospital.

INTRODUCTION: Emergency department deliveries are uncommon in the Singapore setting, but when they do occur, the emergency physician has to be able to deliver the child safely, perform neonatal resuscitation if needed, and try to prevent any birth trauma to the child or complications of delivery in the mother. We present our experience of emergency room deliveries spanning 7 years in a community hospital without obstetric or neonatal backup. MATERIALS AND METHODS: This is a retrospective case series. A search was made through our electronic medical records system for patients presenting in labour or with deliveries from March 1997 to October 2004. They were studied for demographic and social factors, gravidity and parity, as well as any complications (during birth and in the immediate post-delivery period) in both parent and child. RESULTS: Twenty-three patients presented to our emergency department with labour contractions, and 14 progressed to vaginal deliveries. Twelve were single mothers who had hidden their pregnancies, while another 2 married patients had unsuspected pregnancies. No neonate needed resuscitation or airway support, but there were 4 patients without episiotomy who sustained perineal tears, and another 2 patients in whom the placenta could not be delivered. A child (born to a single mother without antenatal care) had a low Apgar score, but improved with oxygen and suctioning. CONCLUSIONS: An emergency department in a non-obstetric hospital should have in place adequate preparations to cater for the occasional unexpected emergency delivery and the associated need for neonatal resuscitation. In our series, there was a high proportion of concealed (hidden) and "unaware" pregnancies presenting in labour. Prompt referral to a maternity hospital with neonatal care should be made for any complications.

Stroke in the Lehigh Valley: racial/ethnic differences.

We investigated black/white differences in stroke rate (standardized morbidity), severity, and subtype, and the relative frequencies of 5 primary risk factors (hypertension, diabetes, myocardial infarction, other heart diseases, and transient ischemic attack [TIA]) using the Lehigh Valley Stroke Register. Blacks had a statistically significant higher, age-adjusted rate of stroke than whites. We found no differences in stroke severity using our measures but blacks had a statistically higher proportion of lacunar stroke, while whites had a higher proportion of embolic stroke. There were no differences in proportions of thrombotic stroke or intracerebral hemorrhage. The relative frequencies of hypertension, myocardial infarction, other heart diseases, and diabetes were higher for blacks, while the relative frequency of TIA was higher for whites. These observations are consistent with other reports that blacks have a higher frequency of stroke and tend to have more small-vessel cerebrovascular pathology than whites.

Defining post-stroke recovery: implications for design and interpretation of drug trials.

Measurement of stroke recovery is complex because definition of successful recovery is highly variable across measures and cut-off points for defining successful outcomes vary. The purpose of this paper is to describe patterns of recovery in stroke patients of varying severity when different measures are used and when different cut-off points are selected. 459 individuals enrolled in a prospective cohort study were assessed within 14 days post stroke and re-evaluated at 1, 3, and 6 months. Recovery was assessed using the NIH Stroke Scale, the Fugl-Meyer Assessment of Motor Recovery, the Barthel Index of Activities of Daily Living, the Physical Function Index of the SF-36, and the Modified Rankin Outcome Scale. Subjects also defined their preference (utility) for their current health state with a time-trade off question. We compared patterns of recovery using the different measures and varying the cut-off points for defining successful recovery. The percentage of patients who are believed to have recovered depends on how recovery is defined. If recovery is defined at the disability level (Barthel > 90), the majority 57.3% of stroke survivors experience a full recovery. Fewer individuals are considered to be fully recovered if impairments are measured (NIH 90, 36.8%. Less than 25% of stroke survivors are considered recovered if recovery is defined relative to reported prior function in higher levels of physical activity. Shifting the definition of recovery on the modified Rankin scale from

Thromboxane synthase inhibitors. Synthesis and pharmacological activity of (R)-, (S)-, and (+/-)-2,2-dimethyl-6-[2-(1H-imidazol-1-yl)-1-[[(4-methoxyphenyl)- methoxy]methyl]ethoxy]hexanoic acids.

A series of substituted omega-[2-(1H-imidazol-1-yl)ethoxy]alkanoic acid derivatives were synthesized and evaluated for their ability to inhibit thromboxane synthase both in vitro and in vivo. Compound 13 was identified as a potent and selective competitive inhibitor of human platelet thromboxane synthase having a Ki value of 9.6 X 10(-8) M. In collagen-treated human whole blood, 13 potentiated levels of 6-keto PGF1 alpha. Enantiospecific syntheses afforded the R and S enantiomers of 13, of which the S enantiomer 13b was the more potent. Compounds 13 and 13b were potent in vivo inhibitors of thromboxane synthase with good oral activity and duration of action.

Structure-activity relationships in an imidazole-based series of thromboxane synthase inhibitors.

Analogues of 4-[[2-(1H-imidazol-1-yl)-1-[[(4-methoxyphenyl)methoxy]methyl] ethoxy]methyl]benzoic acid (5m) were prepared and evaluated as thromboxane synthase inhibitors. A series of esters of 5m showed a parabolic relationship between lipophilicity and inhibition of TxB2 generation in intact platelets, with activities up to 50 times greater than that of dazoxiben. However, on administration to rabbits the ethyl ester 5d had a short duration of action, due to rapid metabolism and excretion via deesterification and beta-glucuronidation. Attempts at replacing the carboxylate group with other potential pharmacophores were unsuccessful.

Predicting stroke recovery: three- and six-month rates of patient-centered functional outcomes based on the orpington prognostic scale.

OBJECTIVE: To provide recovery rates after stroke for specific functions using the Orpington Prognostic Scale (OPS). DESIGN: Prospective cohort. SETTING: Hospital and community. PARTICIPANTS: 413 stroke survivors entered the study 3 to 14 days after suffering a stroke. MEASUREMENTS: A cohort of hospitalized stroke survivors were recruited 3 to 14 days after stroke and assessed at 1, 3, and 6 months poststroke for neurological, functional, and health status. Baseline OPS score was used to predict five functional outcomes at 3 and 6 months using development and validation datasets and receiver operating characteristic (ROC) curves. RESULTS: In 413 stroke survivors, functional recovery rates at 3 and 6 months were similar. Baseline OPS predicted significant differences in recovery rates for all five outcomes (P < .0001 for all five outcomes at 3 and 6 months). Personal care dependence was present at 3 months in only 3% of persons with baseline OPS scores of 3.2 or less compared with over 50% with OPS of 4.8 or higher. Independent personal care, meal preparation, and self-administration of medication were achieved by 80% who had baseline OPS scores of 2.4 or lower compared with less than 20% when OPS scores were 4.4 or higher. Independent community mobility was achieved in 50% of those who had OPS scores of 2.4 or lower but only 3% of those with OPS scores of 4.4 or higher. The area under ROC curves assessing OPS scores against each of the five outcomes ranged from 0.805 to 0.863 at 3 months and 0.74 to 0.806 at 6 months. CONCLUSION: OPS scores can predict widely differing rates of functional recovery in five important functional abilities. These estimates can be useful to survivors, families, providers, and healthcare systems who need to plan for the future.

Lymph node histopathologic findings in cutaneous T-cell lymphoma. A prognostic classification system based on morphologic assessment.

The histopathologic features of 251 lymph nodes obtained from 200 patients with various clinical expressions of cutaneous T-cell lymphoma (mycosis fungoides and Sezary syndrome) were reviewed retrospectively. Lymphomatous involvement, defined as partial or complete effacement of lymph node architecture by malignant cells, was identified in 89 specimens (35%) and was characterized by morphologic variability from case to case. The involved specimens were classified into four major histologic subtypes according to the morphologic appearance of the malignant cells in a manner analogous to a modified Rappaport classification of diffuse non-Hodgkin's lymphomas. Although lymph node involvement was associated with a poor prognosis regardless of histologic subtype, the survival of patients with small cell (cerebriform) subtype was found to be significantly better (median survival time, 40 months) than other subtypes (median survival time, 20 months), possibly because this type of involvement sometimes preceded the development of the more aggressive mixed and large cell subtypes. Dermatopathic lymphadenopathy compared to other reactive patterns had no special prognostic importance other than its more frequent occurrence in black patients and in patients with more extensive skin involvement.

Synaptic relationships between corticocuneate terminals and glycine-immunoreactive neurons in the rat cuneate nucleus.

The present study describes the ultrastructural synaptic relationships between corticocuneate terminals (CCTs) and glycine-immunoreactive (glycine-IR) neurons in the cuneate nucleus of rats using anterograde tract-tracing of wheatgerm agglutinin conjugated with horseradish peroxidase (WGA-HRP) and anti-glycine immunoperoxidase labeling methods. The HRP-labeled CCTs made axodendritic synapses preferentially in the ventral part of the cuneate nucleus near the obex. In a total of 182 CCTs surveyed, 14 of them made direct synaptic contacts with immunoperoxidase-labeled glycine-IR dendrites. The present results suggest that cortical modulation on the sensory transmission of cuneate nucleus may be mediated through glycine-IR neurons.

On techniques for detecting circumscribed masses in mammograms.

A method for detecting one type of breast tumor, circumscribed masses, in mammograms is presented. It relies on a combination of criteria used by experts, including the shape, brightness contrast, and uniform density of tumor areas. The method uses modified median filtering to enhance mammogram images and template matching to detect the tumors. In the template matching step, suspicious areas are identified by thresholding the cross-correlation values, and a percentile method is used to determine a threshold for each film. In addition, two tests are used to remove false alarms from the resulting candidates. The results obtained by applying these techniques to a set of test images are described. They are judged encouraging.

Scoliosis correction maintenance in skeletally immature patients with idiopathic scoliosis. Is anterior fusion really necessary?

STUDY DESIGN: A retrospective evaluation of the occurrence of the crankshaft phenomenon in skeletally immature patients with idiopathic scoliosis. OBJECTIVE: To determine what factors, if any, contribute to a decreased occurrence of crankshaft phenomenon in patients treated with posterior surgery only. SUMMARY OF BACKGROUND DATA: Reports have described the progression of scoliotic deformity, termed the crankshaft phenomenon, in a region of solid posterior arthrodesis in skeletally immature patients. This has led some authors to advocate the use of concomitant anterior discectomy and fusion to prevent crankshaft. METHODS: From 1989 through 1994, 18 Risser 0 patients with thoracic or thoracolumbar idiopathic scoliosis underwent Isola (De Puy-Acromed, Raynham, MA) posterior instrumentation and fusion. They were assessed for evidence of the crankshaft phenomenon, identified by coronal plane deformity progression of 10 degrees or more, or a rib vertebra angle difference of 10 degrees or more. The average age of the patients was 12.5 years (range, 10.5-15.5 years), and the average follow-up period was 39 months (range, 24-68 months). RESULTS: Eleven patients (10 girls and 1 boy) had closed triradiate cartilage at the time of surgery. Their average Cobb angle was 62 degrees before surgery, 21 degrees after surgery, and 22 degrees at follow-up assessment. No patients in this group met the criteria for crankshaft. Seven patients (6 girls and 1 boy) had open triradiate cartilage at the time of surgery. Their average Cobb angle was 62 degrees before surgery, 18 degrees after surgery, and 20 degrees at follow-up evaluation. No patient had a 10 degrees or more increase in rib vertebra angle difference. One patient had more than a 10 degrees increase in her Cobb angle (11 degrees) from postoperative to latest follow-up assessment. Her instrumentation construct, performed in 1989, used sublaminar wires as the caudal anchors. Hooks and pedicle screws are now used. Two of the seven patients with open triradiate cartilage underwent surgery during or before their peak height velocity and displayed no evidence of crankshaft. No deaths, neurologic complications, or infections occurred in either group. CONCLUSIONS: These findings suggest that scoliotic deformity progression can be prevented in skeletally immature patients with idiopathic scoliosis as young as 10 years of age with the use of stiff segmental posterior instrumentation, without the necessity of concomitant anterior arthrodesis.

Reoperation after primary posterior instrumentation and fusion for idiopathic scoliosis. Toward defining late operative site pain of unknown cause.

STUDY DESIGN: Retrospective case series. OBJECTIVES: To determine the frequency and categorize the indications for reoperation in three implant systems (Harrington, Cotrel-Dubousset [C-D], and Isola). To define late operative site pain (LOSP) of no apparent cause as an indication for implant removal and determine the success of implant removal in relieving LOSP. SUMMARY OF BACKGROUND DATA: Late operative site pain of no apparent cause has been discussed briefly in the literature but has not been investigated as a major indication for implant removal. METHODS: One hundred eighty-two of 190 consecutive patients with idiopathic scoliosis (96%) who underwent primary surgery between January 1, 1981, and December 31, 1992, by one surgeon in one hospital, with use of Harrington, C-D, or Isola instrumentation were studied an average of 9 years after surgery to determine the indications for and frequency of reoperation. RESULTS: The overall frequency of reoperation for all instrumentation types combined was 19%: Harrington, 19%; C-D, 24%; and Isola, 14%. By 6 years' follow-up the cumulative risk of reoperation by Kaplan-Meier analysis was Harrington, 14%; C-D, 21%; and Isola, 14%. (statistically nonsignificant difference). The most frequent indication for reoperation was LOSP of no apparent cause: 8% (14 patients) for all instrumentation types combined. The average interval between the initial operation and reoperation for LOSP was 46 months (range, 20-97 months). The frequency of each implant type was Harrington, 6%; C-D, 12%; and Isola, 6%. By 6 years' follow-up, the cumulative Kaplan-Meier risk for reoperation due to LOSP was Harrington, 5%; C-D, 13%; and Isola, 8% (statistically non-significant difference). Of the 14 patients who had instrumentation removal for LOSP, 10 (71%) had successful relief of pain after implant removal. CONCLUSIONS: Occurring regardless of implant type, LOSP of no apparent cause after posterior instrumentation of scoliosis is a distinct clinical entity and is relieved by implant removal in most patients.

The selection of fusion levels using torsional correction techniques in the surgical treatment of idiopathic scoliosis.

STUDY DESIGN: This is a retrospective, consecutive case series, with the index patient included. OBJECTIVES: To evaluate the evolution and effectiveness of instrumentation techniques designed to untwist the scoliosis deformity. SUMMARY OF BACKGROUND DATA: Three-dimensional studies of the idiopathic scoliosis deformity are consistent with the theory that the deformity or deformities evolve as an imperfect torsion or torsions. METHODS: From 1989 through 1995, 102 consecutive patients (84 females, 18 males) underwent surgery with increasing emphasis on torsional correction. One hundred patients (98%), with an average age of 14.3 years (range, 10.5-20.8 years), were observed for an average of 40 months (range, 24-81 months). The upper instrumented vertebra evolved to be the centered vertebra. The lower instrumented vertebra was chosen based on its ability to become horizontal on contralateral bend radiographs and was termed the caudal foundation vertebra. Because these techniques evolved over the first 3 years of the study period, a split analysis was performed to evaluate improvements in correction and correction maintenance over the course of the study. RESULTS: The average Cobb angle was 59 degrees before surgery, 18 degrees after surgery (69% correction), and 22 degrees (63% correction) at latest follow-up. A comparison of the first half of the series with the second half showed no significant demographic differences. Curve correction was significantly improved for King-Moe IIB (thoracolumbar-lumbar curve only), King-Moe III, and King-Moe V curve types in the second half of the series. In the last 4 years, curve correction at latest follow-up for King-Moe IIB curves was 61% for the thoracic curve and 65% for the thoracolumbar-lumbar curve. King-Moe III curves had a 68% correction, and King-Moe V curves had a 50% high thoracic and a 72% thoracic curve correction. Thoraco-lumbar, lumbar, and King-Moe I curves averaged 81% correction of the thoracolumbar-lumbar curve. The angle of thoracic curve inclination improvement at 1 year was maintained at latest follow-up. CONCLUSIONS: This method of selecting instrumentation levels while using torsional correction techniques is safe and reliable. The results were improved with the evolution of these techniques and appear to provide improved correction and correction maintenance compared with that of historical controls.

Patients' perceptions of overall function, pain, and appearance after primary posterior instrumentation and fusion for idiopathic scoliosis.

STUDY DESIGN: This outcome study used patients' responses to the Scoliosis Research Society Outcomes Instrument to discriminate among patients who had undergone surgery for correction of juvenile or adolescent idiopathic scoliosis. OBJECTIVES: To evaluate a surgically treated population by using the SRS Outcomes Instrument. SUMMARY OF BACKGROUND DATA: The Scoliosis Research Society outcomes instrument was developed to help evaluate patient-perceived outcomes after treatment for idiopathic scoliosis. It includes 24 questions designed to investigate seven domains. METHODS: Eligible patients underwent posterior surgery for the first time before their 21st birthdays. One surgeon performed the surgery at one medical center. Of 168 eligible patients, 121 (72%) completed the Scoliosis Research Society outcomes questionnaire. RESULTS: Females reported better outcomes in the function after surgery (P = 0.005) and self-image after surgery (P = 0.01) domains. Preoperative curve pattern comparison demonstrated a significant difference in self-image after surgery among four groups classified according to curve pattern. The thoracolumbar and lumbar group recorded image scores of 5, the highest possible score, 85% of the time. The King-Moe (KM) V group scored 5, 75% of the time; the KM I and II group 48%; and the KM III and IV group 46% (P = 0.0015). After eliminating confounding variables, it was found that white patients reported experiencing less pain in follow-up than did black patients (P = 0.0098). Results were also suggestive that less pain was associated with increased number of fused vertebrae (P = 0.027). CONCLUSIONS: The strongest predictors of self-perceived favorable outcome among patients were female sex and white race. It is also suggested that longer fusions to L1 through L3 lead to less perceived pain than with shorter fusions.

Development of a comprehensive assessment toolbox for stroke.

Comprehensive databases for the assessment of individuals with stroke are essential for clinical management and evaluation of outcomes for quality management and research. The purpose of this article is to describe a comprehensive data system or "toolbox" developed by clinicians and researchers at the Center on Aging at the University of Kansas Medical Center. The choice of assessments for the toolbox resulted from the Agency for Health Care Policy and Research Post-Stroke Rehabilitation Guidelines, results of the Kansas City Stroke Study, and the authors' work to develop a new stroke measure-the Stroke Impact Scale.
