The purpose of this study was to identify, using an intensive literature review, the primary historical factors and events that shaped the evolution of current splinting technique and practice. Publication dates determine the chronological order of events, and splints are defined according to the ASHT Splint Classification System. Purposes of splinting are analyzed and listed according to frequency of citation in splint manuals and books, and a historical review of splinting practice describes splints, events, and persons who influenced the evolution of splinting from the time of Hippocrates through the 20th century. Factors influencing splint development include disease, political conflict, advancements in medicine and technology, agency and organizational decision making, centers of practice, and availability of information. Infection, polio, war, technology, plastics, surgical advances, soft tissue remodeling, anatomy, biomechanics, government agencies, hand centers, seminars, professional organizations, publications, and a classification system have all played important roles in 20th century splinting practice.
UNLABELLED: Two experiments examined reliability and classification accuracy of a narration-based dynamic assessment task. PURPOSE: The first experiment evaluated whether parallel results were obtained from stories created in response to 2 different wordless picture books. If so, the tasks and measures would be appropriate for assessing pretest and posttest change within a dynamic assessment format. The second experiment evaluated the extent to which children with language impairments performed differently than typically developing controls on dynamic assessment of narrative language. METHOD: In the first experiment, 58 1st- and 2nd-grade children told 2 stories about wordless picture books. Stories were rated on macrostructural and microstructural aspects of language form and content, and the ratings were subjected to reliability analyses. In the second experiment, 71 children participated in dynamic assessment. There were 3 phases: a pretest phase, in which children created a story that corresponded to 1 of the wordless picture books from Experiment 1; a teaching phase, in which children attended 2 short mediation sessions that focused on storytelling ability; and a posttest phase, in which children created a story that corresponded to a second wordless picture book from Experiment 1. Analyses compared the pretest and posttest stories that were told by 2 groups of children who received mediated learning (typical and language impaired groups) and a no-treatment control group of typically developing children from Experiment 1. RESULTS: The results of the first experiment indicated that the narrative measures applied to stories about 2 different wordless picture books had good internal consistency. In Experiment 2, typically developing children who received mediated learning demonstrated a greater amount of pretest to posttest change than children in the language impaired and control groups. Classification analysis indicated better specificity and sensitivity values for measures of response to intervention (modifiability) and posttest storytelling than for measures of pretest storytelling. Observation of modifiability was the single best indicator of language impairment. Posttest measures and modifiability together yielded no misclassifications. CONCLUSION: The first experiment supported the use of 2 wordless picture books as stimulus materials for collecting narratives before and after mediation within a dynamic assessment paradigm. The second experiment supported the use of dynamic assessment for accurately identifying language impairments in school-age children.
PURPOSE/OBJECTIVES: To provide an overview of childhood acute lymphoblastic leukemia (ALL), including epidemiology, clinical presentation, diagnostic classification, prognostic factors, current treatment, long-term sequelae, and nursing management. DATA SOURCES: Journal articles, books, and clinical experience. DATA SYNTHESIS: Childhood ALL is a heterogeneous disorder, and current treatment is tailored to risk factors (e.g., initial white blood count, cytogenetic properties of the leukemic blasts). Risk-directed therapy ensures that children with a higher risk of relapse receive more intensive treatment, whereas those with lower risk disease receive less toxic therapy with decreased potential for treatment-related morbidity. Quality of life in long-term survivors is a significant issue. Late sequelae of treatment can include neurocognitive difficulties, endocrine dysfunction, secondary malignancies, and cardiomyopathy. CONCLUSIONS: With risk-directed therapy, cure rates for childhood ALL continue to improve. At least 80% of children diagnosed with ALL today are expected to survive their disease. IMPLICATIONS FOR NURSING PRACTICE: Nurses caring for children with ALL can have a significant impact on the children's overall health, from diagnosis through long-term follow-up. Nursing interventions encompass the domains of physical and psychosocial care, as well as patient and family education. Assisting the child and family to maintain normalcy in the face of chronic illness, as well as fostering the family's hope for the future and their belief in the child's potential for survival, are key nursing strategies that promote the child's growth, development, and psychological health.
OBJECTIVE: To develop a standardized histopathological classification system for chronic prostatitis (standardized description of prostatic inflammatory infiltrates) based on a literature review, extensive prospective evaluations in two recognized prostatitis research centres and widespread consensus of international urological centres identified as having major expertise or interest in chronic prostatitis. METHODS: Relevant articles for review were identified by a Medline search undertaken by the Cochrane Review Group in Prostate Diseases and Urologic Malignancies, and cross-checking bibliographies of retrieved studies, reviews, book chapters and abstracts of the American Urological Association and International Prostatitis Collaborative Network Annual Meetings. Initial drafts were based on classification systems independently developed by the Prostatitis Research Centers at Queen's University in Canada and University of Washington in the USA. A collaborative draft was distributed to 20 urological/pathological clinical centres who participated in the North American Chronic Prostatitis Collaborative Research Network and First International Prostatitis Collaborative Network. A consensus classification system was then distributed to the participating panel for acceptance. RESULTS: The literature review identified a reasonably consistent description of inflammatory infiltrate locations and patterns that were further incorporated into the draft based on the Queen's University and University of Washington proposals. Eighteen (90%) of the identified Prostatitis Centers participated in the revision of the draft and the final consensus process. The final consensus document classifies prostatic inflammation according to its extent and grade/severity in each tissue compartment (location). Conclusion The consensus of the expert panel was that this classification system can be used in the evaluation of prostatic inflammation in prostate biopsies, transurethral resected prostate chips or prostatectomy specimens. A standardized accepted framework to describe histopathological prostate inflammation will prove useful in evaluating prostate disease.
The present TNM classification of ophthalmic malignant tumors (lid cancer, malignant melanoma of the lid, conjunctival cancer, conjunctival malignant melanoma, uveal malignant melanoma, retinoblastoma, orbital sarcoma and lacrimal gland cancer) has been explained according to the UICC in a book edited by M. H. Harmer and J. A. Oosterhuis. Five studies concerning the difference in clinical results with and without a treatment were shown to confirm the meaning and importance of TNM classification of ophthalmic malignancies.
The purpose of this study was to find out whether taxonomic classification of MCQ items reflected differences in student behaviour. The data from one of this University's official open-book exams, in which students answer sixty MCQ items distributed over twelve content-areas of physiology were examined. The responses from all 153 candidates were then subjected to factor analysis. Analysis of individual item scores was unrewarding. Analysis of scores for item-groups based on taxonomy and content resulted in the identification of three factors, which carried predominant loadings from recall or look-up items, interpretation items, and problem-solving items, respectively.
Alice Hamilton described fatal work injuries from acute hydrogen sulfide poisonings in 1925 in her book Industrial Poisons in the United States. There is no unique code for H2S poisoning in the International Classification of Diseases, 9th Revision; therefore, these deaths cannot be identified easily from vital records. We reviewed US Occupational Safety and Health Administration (OSHA) investigation records for the period 1984 to 1994 for mention of hazardous substance 1480 (hydrogen sulfide). There were 80 fatalities from hydrogen sulfide in 57 incidents, with 19 fatalities and 36 injuries among coworkers attempting to rescue fallen workers. Only 17% of the deaths were at workplaces covered by collective bargaining agreements. OSHA issued citations for violation of respiratory protection and confined space standards in 60% of the fatalities. The use of hydrogen sulfide detection equipment, air-supplied respirators, and confined space safety training would have prevented most of the fatalities.

The kingdom Protoctista comprises some 30 phyla, including the eukaryotic anaerobes that permanently lack mitochondria, the Phylum Archaeprotista, with its three classes: (i) Archamoebae, e.g., Pelomyxa, Mastigina, (ii) Metamonada, e.g., Giardia, Pyrsonympha, and (iii) Parabasalia, e.g., Trichomonas, Calonympha, and the Phylum Microspora (Microsporidia), e.g., Vairimorpha. These and all algae, protozoa, labyrinthulids, "water molds" (oomycota, plasmodiophorans, hyphochytrids, chytrids, etc.) and other eukaryotes excluded from plants, animals and fungi are detailed in the Handbook of Protoctista. The Illustrated Glossary of Protoctista contains descriptions of the morphology and taxonomy of these microorganisms, including the many equivalent and homologous structures with different names. The Glossary has also been made into a Macintosh-compatible CD-ROM disk.
OBJECTIVE: A pilot study was conducted to undertake a baseline assessment of errors reported in community optometric practice. The feasibility and acceptability of a method for recording staff-reported errors in optometric community practice was investigated. DESIGN: An anonymous self-reporting system was introduced in order to collect information regarding errors/untoward events in community optometric practice. SETTING: UK community optometric practice. MAIN OUTCOME MEASURES: Classification of errors according to a previously published study pertaining to general medical practice in the same geographical area. RESULTS: Thirty-six notebooks were distributed to 10 participating community optometric practices. At the end of the 1 month study period the note books were returned and the 439 entries made were classified into seven categories: optical prescriptions (18.2%), communication (35.5%), administrative (15%), appointments (2.3%), equipment (11.9%), clinical (10.3%) and other (6.9%). CONCLUSION: A previously developed classification of errors in general medical practice was found to be equally applicable to community optometric practice. This study forms the basis of providing an acceptable and practical methodology, which can be applied by Primary Care Trusts (PCTs) when developing their risk management strategy to include optometry.
Alexander Marcet was an authority on urinary calculi and their analysis when few medical practitioners appreciated the usefulness of chemistry in the explanation and treatment of disease. In An Essay on The Chemical History and Medical Treatment of Calculous Disorders, he described the discovery of an xanthine stone. He drew line illustrations of simple chemical apparatus useful for bedside analysis. His microtechnique used drops of solution and pinhead pieces of calculi; reagents were acids and alkalies and the blowpipe in conjunction with a small alcohol lamp. He reported the earliest description of a disorder later named "alcaptonuria". Marcet's work and that of a few others, on the chemical composition of urine and calculi, laid the foundations of our present knowledge. Between 1807 and 1820, his lectures to the medical students at Guy's Hospital were illustrated by experiments. Jane Haldimand Marcet wrote the very popular CONVERSATIONS: on Chemistry (16 editions in Great Britain). Her book dominated elementary chemical instruction during the first half of the 19th century. She followed Lavoisier's scheme of classification and explained chemical reactions in terms of affinity, aggregation, gravitation, and repulsion. Her advocacy that experimentation accompany lecture was new. The availability of serious scientific education in the new women's academies set the stage for increasing women's involvement in science. She also published a series of CONVERSATIONS: The topics were Political Economy, Natural Philosophy, and Vegetable Physiology.
Acute pancreatitis, a broad spectrum pathology, has a variable incidence, closely related to the geographic differences in its most frequent etiologies. Its pathogenesis remains to be cleared, with several proposed mechanisms. Pancreatitis' diagnosis, severity evaluation and the use of imagiologic and endoscopic auxiliary exams must be based in scientifically settled criteria. Treatment depends, mostly, on the episode's severity, but is mainly supportive. Pancreatitis' complications are responsible for the lethal cases and their classification as early, intermediate and late has practical utility. Based on a literature review of the pathology, including reference books and computer data bases, a systematized approach algorithm is proposed.
Conceptual models are useful devices for organizing complex material and examining interrelationships among variables. For example, speakers at the 1990 II STEP Conference presented a systems model of motor control, the dynamical systems model as used in studying infant motor development, and the World Health Organization model as a systematic approach to the description of impairments, functional limitations, and disability. The purpose of this perspective is to provide examples of the usefulness of models of disability in organizing research, educational materials, and measurement in clinical practice. The disability model of the National Center for Medical Rehabilitation Research was used: (1) to design a measurement strategy for assessing effects of spasticity reduction in a child with cerebral palsy, (2) to develop a new assessment of functional motor performance in infants, and (3) as the conceptual framework for a comprehensive reference book for the practice of pediatric physical therapy (the current edition has been reformatted to conform to the International Classification of Function, Disability and Health). Similar models of the dimensions of disability have guided extensive development of tests designed by physical therapists for assessing function and quality of life in children with neurologic conditions.
OBJECTIVE: To review the clinical presentation, current methods of diagnosis and classification, treatment modalities, and novel treatment approaches of acute myelogenous and lymphoblastic leukemia. DATA SOURCES: Professional journals, web sites, and books. CONCLUSION: The incidence of acute leukemia is increasing. As the population ages, it is anticipated that an even greater number will be diagnosed with this malignancy. The development of monoclonal antibodies, the recognition of the benefit of graft versus leukemia effect, and targeted therapies have improved overall survival rates. Still, age remains a significant prognostic variable. More research is needed to improve both the quality and the quantity of life for these patients. IMPLICATIONS FOR NURSING PRACTICE: Nurses must understand the rationale and implications of each phase of treatment to educate patients, administer treatments, manage side effects, and provide support throughout the continuum of care.
A comparison is made between compilations of times of origination and extinction of fossil marine animal families published in 1982 and 1992. As a result of ten years of library research, half of the information in the compendia has changed: families have been added and deleted, low-resolution stratigraphic data been improved, and intervals of origination and extinction have been altered. Despite these changes, apparent macroevolutionary patterns for the entire marine fauna have remained constant. Diversity curves compiled from the two data bases are very similar, with a goodness-of-fit of 99%; the principal difference is that the 1992 curve averages 13% higher than the older curve. Both numbers and percentages of origination and extinction also match well, with fits ranging from 83% to 95%. All major events of radiation and extinction are identical. Therefore, errors in large paleontological data bases and arbitrariness of included taxa are not necessarily impediments to the analysis of pattern in the fossil record, so long as the data are sufficiently numerous.
Aretaeus of Cappadocia's classification of headache has been referred to for many centuries. Several Latin translations and an English translation (1856) of his books have been published in the past. We translated the pertinent texts on headache from the Greek text as published by Hude in 1958. In this paper, we present an annotated translation preceded by an outline of contemporary knowledge of headache from Celsus' De Medicina. Although symptomatic headache was most probably involved in the types of headache identified by Aretaeus and the making of retrospective diagnoses is hazardous, the terms heterocrania and cephalea may be compared with what today we would call migraine and tension type headache respectively.
BACKGROUND: The aim of the present study was to describe, on the basis of specific classification criteria and for a period of two years after delivery, the prognosis for women suffering from pregnancy-related pelvic joint pain, and to describe the characteristics influencing the prognosis. METHODS: One thousand seven hundred and eighty-nine pregnant women who were booked for delivery at Odense University Hospital formed a cohort to investigate the prognosis. Women whose reported daily pain from pelvic joints could be objectively confirmed were divided, according to symptoms, into five subgroups (n=405) - four classification groups (pelvic girdle syndrome, symphysiolysis, one-sided sacroiliac syndrome and double-sided sacroiliac syndrome) and one miscellaneous. The women in the five subgroups were re-examined at regular intervals for two years after delivery or until disappearance of symptoms (whichever was less). Thre hundred and forty-one women from the 5 subgroups participated in the postpartum follow-up. RESULTS: The majority (62.5%) of women in the four classification groups experienced disappearance of pain within a month after delivery. Two years after parturition 8.6% were still suffering from pelvic joint pain (determined subjectively and objectively). Persistence of pain was found to vary significantly from one classification group to another. None of those initially classified as suffering from symphysiolysis had pain 6 months after delivery in comparison to the 21 percent of those with pelvic girdle syndrome who continued to have pain at the two-year mark. CONCLUSIONS: This study shows that pregnancy-related pelvic joint pain had an excellent postpartum prognosis (in general) in three out of four classification groups. The women with pelvic girdle syndrome (pain in all 3 pelvic joints) had a markedly worse prognosis than the women in the other three classification groups. High number of positive test and a low mobility index were identified as giving the highest relative risk for long term pain.
