Disabilities of the arm, shoulder and hand (DASH) questionnaire: Determining functional activity profiles in patients with upper extremity disorders.

The Disability of Arm, Shoulder and Hand (DASH) questionnaire is a standardized measure which captures the patients' own perspective of their upper extremity health status. Based on the scores of the DASH modules: symptoms, function and sport, this follow-up study of 590 hand-injured subjects from 11 diagnostic groups evaluated impairments and disabilities perceived 2 to 5 years postoperatively. Secondly, we explored the relationships between the diagnostic groups at the individual DASH item level. Exploratory testing of statistical significance showed that the DASH modules differentiated well among the groups (ANOVA P-value 0.001) and further differences existed at the item level, so that functional activity problem profiles could be developed for each diagnostic group. Our findings confirm that the DASH is a useful instrument for outcome evaluation. Moreover, in view of the continuing challenge to provide comprehensive care which meets patients' needs in the shortest space of time, we consider that DASH has potential in the development of patient-centred treatment programmes which are tailored to the individual patients' requirements and have relevance to their daily activities.

[Does the disability of shoulder, arm and hand questionnaire (DASH) replace grip strength and range of motion in outcome-evaluation?].

Scoring systems currently used to evaluate functional disabilities in upper extremity conditions frequently combine so-called "objective" parameters such as grip strength and range of motion with "subjective" parameters such as pain. Since its introduction, the Disabilities of Arm, Shoulder and Hand Questionnaire has proven useful in the pre- and postoperative evaluation of functional limitations of the upper extremity. This study examines the relationship between DASH scores, the so-called "objective" parameters of grip strength and range of motion and those of "mixed scores" such as Krimmer and Cooney Scores. Based on the data of six diagnostic groups, Spearman's correlation coefficients were calculated. There was no correlation between DASH scores and range of motion, however, some of the diagnostic groups showed a moderate correlation between DASH scores and grip strength. Both the Krimmer and Cooney scores showed a significant correlation with the DASH scores, indicating that these "mixed-scores" can be replaced by the DASH. Since it has been shown that grip strength and range of motion do not capture patients' functional limitations adequately, their continued use in the evaluation of upper extremity conditions should be the topic of further discussion.

[Standardisation and validation of the German version 2.0 of the Disability of Arm, Shoulder,Hand (DASH) questionnaire].

The Disability of Arm, Shoulder, Hand (DASH) Version 2.0 questionnaire captures the subjective experience of patients regarding their own health. This 78-item instrument was developed by the American Academy of Orthopedic Surgeons (AAOS), the Council of Musculoskeletal Specialty Societies and the Institute for Work and Health,Toronto and measures components of health-status relevant to upper-extremity conditions. We translated and validated DASH with the aim of producing a tool which could also be used in German-speaking countries. The paper reports the method of translation and cross-cultural adaptation which was carried out according to the AAOS guidelines. The result was a standardised German version of DASH. Psychometric testing of the translated questionnaire was carried out with 6 samples (n=342) who had undergone hand surgery for a variety of conditions. The study yielded good results across all groups with regard to the construct, criterion and content validity. We confirm that the German version is suitable for use in future studies.

[The "Shoulder, Arms and Hand Disability Questionnaire" as a scale for identification of the diagnosis-specific activity profile].

Functional disabilities of the upper extremities have a considerable social and economic impact so that interest was aroused in developing a valid and reliable instrument suitable for international use. The Disabilities of the Arm, Shoulder, and Hand questionnaire is a self-report measure recording functional limitations in the upper extremity. A German version is now available in German-speaking countries. Previous studies have been concerned with the evaluation of DASH scores. Based on the data of four diagnostic groups, this study explores DASH's ability to identify diagnosis-specific limitations at the item level. The data were pooled and examined with regard to significant differences within the groups. Diagnosis-specific limitations could be identified within all groups, indicating that DASH is capable of expressing diagnostic entities as well as summed scores. Consideration of the individual profiles opens the possibility of using DASH as a prognostic tool to anticipate functional problems arising during rehabilitation following surgical interventions.

[The DASH(Disability of Arm-Shoulder-Hand) Questionnaire--a new instrument for evaluating upper extremity treatment outcome].

The paper presents the translation of a new measurement tool, the DASH Questionnaire. The DASH (Disability of Arm--Shoulder--Hand) is an outcomes data collection instrument which has been developed by the "American Academy of Orthopaedic Surgeons", the Council of the "Musculoskeletal Specialty Societies", and the "Institute for Work and Health", in order to assess outcomes among patient groups with musculoskeletal disorders. Using a self-report system, patients attribute scores of 1 to 5 on 30 items relating to functional activities and symptoms; a further optional module contains four items relating to disability levels among musicians and athletes. The raw score is then transformed to a 0 to 100 scale, whereby 0 reflects minimum and 100 maximum disability. The subjective nature of this instrument makes it suitable for both postal or in situ clinical surveys. The instrument is in the process of validation for use with a German population.

Inverted Y duplication of the ureter associated with a distal limb ectopic to the seminal vesicle.

Inverted Y duplication of the ureter is a rare anomaly. We report on a 24-year-old man who presented with urolithiasis and azoospermia in a solitary functioning kidney with an inverted Y ureteral duplication. To our knowledge our case represents the first documentation of ectopic emptying of 1 limb of the inverted Y ureter into the seminal vesicle. The embryology and management of this complex case are discussed.

Study of upper extremity growth and development using human embryos and computer-reconstructed models.

This study investigated the apical ectodermal ridge and early vasculature of the human limb bud by use of histologic techniques and a new method of computer modeling. Fourteen human embryos were studied (more than 10,000 sections) microscopically and the embryonic limbs were reconstructed three-dimensionally by use of a serialized programming method. The apical ectodermal ridge consists of an extensive band of specialized cells, located over the rim of the limb surmounting a strip of rapidly-dividing mesenchymal cells. It is consistently supplied by a large vessel that shows extensive central branching.

Three-dimensional computer graphic modeling of ballistic injuries.

Multiple variables affect the tissue destruction caused by missiles, and the interaction of these variables is incompletely understood. The recently developed technology of computerized solid modeling now makes it possible to analyze these parameters in three dimensions. A technique for creating solid models of organic structures is described. The tissues within the boundaries thus defined are ascribed physical attributes by means of finite element analysis with data derived from empirical studies. An interactive user-friendly program is being developed combining this modeling with a probabilistic scheme (Monte Carlo simulation) to describe a variety of wounding scenarios. The data from these predictions will be compared with information from wound registries and the model refined until it can project consistently accurate patterns of injury.

Computer graphic modeling in surgery.

The application of computer-based solid modeling techniques to human anatomy shows great promise for enhancing surgical instruction and research. Such advances will directly benefit patient care. The increasing availability of powerful modeling programs for the microcomputer and the interactive peripheral technologies make the delivery of this new modality practical at the present time. We continue to refine our methodology for producing accurate and esthetic anatomic models and have developed a technique for three-dimensional "sculpting" of elongated structures. We continue to explore the possibility of using sectional scanning data to create anatomic images. Several applications have been described, ranging from surgical simulations to a ballistic injury model, in order to indicate the potential scope of this powerful technology.

Bright-light amaurosis fugax: an unusual symptom of retinal hypoperfusion corrected by external carotid revascularization.

The eye often serves as an important monitor of carotid artery disease by manifesting visual disturbances before cerebral events. The most typical ocular symptom complex is amaurosis fugax characterized by loss of vision in one eye that occurs suddenly and clears within seconds to minutes. This symptom is a hallmark of carotid artery disease and is usually caused by an embolic event. Although monocular visual disturbance on a hemodynamic basis is a more unusual manifestation of carotid artery disease, significant stenosis in combination with a low-flow state can cause transient, unilateral telescoping of vision. This report describes another visual disturbance associated with carotid artery disease in which unilateral visual loss occurred upon exposure to bright light. We term this syndrome bright-light amaurosis fugax and document successful treatment by external carotid artery revascularization in two patients.

Obstructive jaundice secondary to hepatoma. Case report and literature review.

A 67-year old male, who presented a clinical picture of obstructive jaundice with cholangitis, was found to have hepatoma tumor embolus blocking the common duct. The site of invasion was the right hepatic duct. There are 15 such cases reported in the literature. Hepatoma rarely presents with obstructive jaundice. A clinical picture of biliary colic or cholangitis is frequently misleading. Invasion of a hepatic duct large enough to allow formation of a tumor embolus implies tumor close to the bifurcation of right and left hepatic ducts and has precluded effective surgical treatment in all but one case.
