Multimedia Capture, Collaboration and Knowledge Management 145 Enriching Collaborative Consultations During a telehealth consultation between patient and clinician various medical docu- ments might be used including laboratory reports, photos of injury/skin lesions, x-rays, pathology slides, EKGs, MR/CT images, medical claim forms, prescriptions, clinical results, case reports, and other documents. Some of the documents like photos and images might have been captured using camera during patient visits, while other clinical (lab reports) or financial information (insurance claim) were gleaned from other informa- tion systems. Face-to-face video conferencing is commonly used in telemedicine not only for personalized remote communications, but also for regulatory reasons as evidence of a consultation the costs for which can subsequently be reimbursed. It would be convenient if a clinician could combine, interface, convert, and extract disparate medical information such as those listed above from peripheral devices like photo cameras, video conferencing session, content management systems, PACS, and regular office documents into a Web-based composite document. Thereafter, it would be convenient if this composite document could be used as the basis for browser-based collaboration (whether it is offline or real time) between various participants. Such a composite document generated should combine all relevant information needed for a particular collaboration session into one seamless document so that effective offline or real time collaboration can occur. A user could choose specific pages from document(s) stored locally and automatically have the selected pages converted to HTML format and hyperlinked with each other to form a composite document. Then, he or she could highlight important parts of the document and add personal comments with the help of voice and graphic annotations using our multimedia presentation software, called ShowMe (Sastry, Lewis, & Pizano, 1999). The multimedia annotation technology developed is unique as it not only captures the spatial nature but also the temporal aspects. For instance, the multimedia annotation on a document would capture a synchronized temporal voice, graphic and mouse pointer annotations. Finally, the user could save the composite document along with the annotations on the local web server, and this document is referred to as the collaboration document. Associated with this collaboration document is some metadata in the form of an XML schema that describes this document. This metadata is finally uploaded to the central server and its URL on this central server can then be sent to other participants. Participants can view the collaboration document via the URL of the metadata stored on the central Web server using a lightweight Web-browser player. As the collaboration documents are stored locally, they are amenable to document management tasks, including deleting, moving, and so on. However, any such document management task must be accompanied by making an appropriate change in the metadata located at the central Web server. The above process allows various users to collaborate over documents quickly and easily by only sharing information relevant to the topic in question. In addition, there is increase in productivity as users can quickly exchange information without having to exchange e-mail to explain problem/solution. Figures 2, 3, and 4 show a particular workflow implemented to demonstrate the spectrum of modes of browser-based collaboration using office documents and Web content.

As only specific parts of different documents might be needed for a particular collaborative session, participants are able to combine, on the fly, specific pages from several documents with different formats into one seamless Web-based composite document. Multimedia Enhanced Store & Forward Collaboration: A clinician can quickly create one seamless web-based composite multimedia document by combining various medical information segments like images, photos, EKGs together. Synchronous voice, graphic and mouse annotations can then be easily added on top of the composite document before sending it via regular e-mail. The recipient needs only a web browser to view the composite document along with the voice and graphic annotations. Instant Messaging Based Document Collaboration: This uses presence and availability of different participants to setup collaboration. Also, this allows asynchronous messaging of voice and graphic annotations within a real-time collaboration session.

Multi-participant Real-Time Collaboration: Several remote participants using their web browser can collaborate on the generated composite medical document. These modes of collaboration—whether off-line, IM-based, or real-time—take place using a regular web browser with the requisite collaboration plug-ins.
Most of the labral contribution is posterior 36 6 Classifications of pathology of long head of the biceps tendon c d Fig buy cheap cialis professional 40 mg erectile dysfunction evaluation. There are equal contributions to both the anterior and the posteri- or parts of the labrum buy generic cialis professional 40 mg on-line causes of erectile dysfunction in late 30s. Most of the labral contribution is anterior, with a small contribution to the posterior labrum 6. When this is encountered, it has to be classified as a complex SLAP type 2 and 3 or type 2 and 4 lesion. Of these, 62% had lesions that fit within the classifications system of Sny- der [122, 123]. Thirty-eight percent in this study had significant biceps tendon-superior labrum injury that did not fit into the classification system proposed by Snyder [122, 123]. The authors have observed three types of type II SLAP lesions by anatomic location: n Anterior SLAP lesion: anterosuperior type II SLAP lesion (Fig. Topographical classification of LHB lesions Lesion Zone Pathology Lesions of the origin of the LHB I SLAP lesions I±IV Andrews lesions Supratubercular lesions II Isolated tendinosis/tendinitis (Partial) tears of LHB (Partial) tears of LHB in Rotator cuff lesions Supratubercular instability (Walch I) Sulcus associated lesions III Subluxation/dislocation out of the bicipital groove (Walch II) without lesions of postero- superior rotator cuff but where applicable accompanied with a lesion of the subscapularis tendon (and capsule) Lesions below the bicipital groove IV Peripheral of proximal LHB (e. It must be stressed that the distinction is not always clear; the degenerated and inflamed tendon is more prone to trauma and, conversely, repeated trauma may result in changes in the tendon indistinguishable from those of inflammation. Nevertheless, this classifi- cation can help with the organization of the pathogenesis of these disor- ders and formulation of protocols for appropriate management. Subluxation n Type I: superior subluxation n Type II: unstable at proximal portion of groove n Type III: subluxation following melanin or nonunion of lesser tuber- osity 2. Dislocation n Type I: extraarticular, combined with partial tear of subscapularis n Type II: intraarticular, combined with full-thickness tear of subscapu- laris III. Superior labral tears (SLAP lesion) n Type I: significant fraying n Type II: complete detachment of biceps tendon and superior labrum from glenoid n Type III: ªbucket-handleº tear of superior labrum n Type IV: central superior labrum tear with extension into the biceps 42 6 Classifications of pathology of long head of the biceps tendon 6. Three different types of biceps tendon subluxation were recognized: n Superior subluxation (type I): The circular sling of the superior glenohumeral and coracohumeral liga- ments (i. The subscapularis tendon, which attaches to the lesser tubercle just below the superior glenohumeral ligament, is largely intact; otherwise a true dislocation is present. The lesion above the en- trance to the groove is sometimes marked by an accompanying partial lesion of the supraspinatus tendon on the articular side, directly at the lateral groove entrance, where it forms the roof for the biceps tendon. The pathologic substrate of the type I subluxation is discontinuity in the tendo-ligamentous rotator interval sling surrounding the long biceps tendon (i. With this type of lesion, the tendon slips over the medial rim of the bony groove and ªridesº on the border of the lesser tuberosity. The causal lesion is a detachment of the outermost fibres of the subscapularis tendon. Tearing of the superficial (outer) portions that line the floor of the groove and help anchor the long biceps tendon al- lows the tendon to displace to a medially subluxated position. The prin- cipal criterion for a type II biceps tendon subluxation is a partial rup- ture of the outer, superficial tendinous portions of the subscapularis muscle, allowing the biceps tendon to ride over the bone of the lesser tuberosity. The type II lesion may be confined to the superior half of the groove or may involve its entire length. The deeper portions of the subscapu- laris tendon still insert into the lesser tuberosity, separating the bi- ceps tendon from the joint space. Invariably there is a rupture of the common attachment of the superior glenohumeral ligament and cor- acohumeral ligament. The biceps tendon, then, is displaced over the anterior wall of the groove and slips or glides medially over the torn fibres of the subscapularis tendon. The clavipectoral fascia covers this 44 6 Classifications of pathology of long head of the biceps tendon lesion externally, and this might give the impression that the supsca- pularis tendon is intact over its full-thickness. It has been shown, however, that the outer attachment of the supscapularis tendon is al- ways torn. This type of dislocation corresponds in its evolution to a type II subluxation but represents a more advanced stage. Besides the superficial lesion of the subscapularis tendon, there is frequently an associated tear of the rotator cuff.
This fascinating history extends to the present day purchase cialis professional 20 mg without prescription erectile dysfunction caused by hydrocodone, as radio frequency lesion generation generic cialis professional 40mg erectile dysfunction treatment cincinnati, deep brain stimulation (DBS), and other approaches to disorders of the basal ganglia are proposed and tested in patients with movement disorders. First, the neural systems likely to subserve motor control (basal ganglia, globus pallidus, and ventral thalamus) are still only loosely integrated into schemes that can account for normal motor control, although lesions of these structures are clearly associated with pathological disorders of movement. This chapter provides an overview of the spectrum of movement disorders, discusses the functional connectivity of basic motor-associated circuits in the brain, and reviews current surgical treatments of movement disorders. We hypothesize that the next generation of movement disorder treatments will involve a number of new approaches including more sophisticated sensing and stimulation systems, novel medical delivery systems, new medications, and gene therapy. These treatment-related dyskinesias are relatively newly discovered phe- nomena, noticed only in the past 20 years when patients have remained on L-dopa therapy for longer periods. This crossover from a predom- inantly hypokinetic to a predominantly hyperkinetic movement disorder solely due to treatment effects has blurred the traditional distinctions among movement disor- ders. As understanding of the genetic basis of movement disorders increases, a more proper classification scheme for movement disorders may become available. The clinical features of parkinsonism arise in a wide variety of degenerative disorders including striatonigral degeneration, progressive supranu- clear palsy, corticobasilar degeneration, and Shy–Drager syndrome. Parkinsonism may also result from toxins such as carbon monoxide, methanol, mercury or MPTP from stroke or from head injury. It is typically given with the dopamine decarbox- ylase inhibitor carbidopa to prevent degradation of L-dopa in peripheral tissues. After 8 to 12 years of levodopa–carbidopa (Sinemet) therapy, patients may begin to © 2005 by CRC Press LLC experience the long-term side effects of these medications, including dyskinesias, and may be considered for DBS. DBS appears to allow a long-term reduction in Sinemet dosage, reducing the severity of medication- induced dyskinesias. Furthermore, the resistance of many symptoms to both medical and surgical therapy, including speech impairments, abnormal postures, gait and balance problems, autonomic dysfunctions, cognitive impairments, and psychi- atric disturbances provides goals for the development of new forms of treatment. Pathological tremor occurs in a range of 4 to 7 Hz and preferentially affects particular muscle groups, such as distal limbs. Pathological tremor may be subclassified into two main categories: action (or postural) tremor and rest tremor. Such tremor often arises in the second decade of life, may worsen with age, and is most pronounced during attempts to maintain a fixed posture. The tremor is typically worsened with emotion, fatigue, or caffeine and is generally improved with alcohol. Pharmacological thera- pies for essential tremor include the beta-blocker propranolol and the anticonvulsant primidone. Other forms of action tremor may occur with neurological disorders such as multiple sclerosis or meningoencephalitis. The tremor subsides with action such as lifting a cup, but immediately resumes when the hand is still, such as when a cup is held close to the mouth. The tremor may respond to pharmacological therapy with the phenothiazine derivative ethopropazine (Parsidol) or the anticho- linergic trihexyphenidyl (Artane). Manifestations of dystonic conditions may be progressive, initially appearing as mannerisms, and later becoming more persistent. This disorder, termed torsion dystonia of childhood, involves progression from intermittent and focal involuntary movements to persistent contor- tions of the entire body. In some instances, dystonia may be occupationally related, such as spasms of the hand (writers), spasms of the hand and neck (violinists), and spasms of the lip (trombonists). Although L-dopa, bromocriptine, benzodiazepines, and other pharmacological interventions may be helpful in some cases, few dystonia patients generally respond to medical management. In many cases of focal dystonia, therapy consists of transient disruption of muscle function with botulinum toxin. In the past, stereotactic lesioning of the ventrolateral thalamus or the pallidum resulted in substantial improvements in axial symptoms for some patients. Interestingly, such pallidal stimulation requires a considerable period before showing treatment effects.
