The authors have achieved excellent to good results in 90% of patients with a 1.2% complication rate. Patients preferred ECTR to open surgery. However, ECTR is technically more demanding and complications may occur even with considerable experience; the single tendon injury the authors have had occurred on the 35th patient. More importantly, in 8 procedures the authors could not predict that ECTR could not be performed. They believe this recognition is crucial to good results; if they had persisted with ECTR in those 8 patients, the complication rate may have been higher and the success rate lower. The surgical error rate was far higher during cadaver operations and the authors feel that they learned a great deal during this experience. They strongly believe that ECTR is not a technique that can be adequately learned in a weekend seminar. Reported complications of ECTR have increased as more surgeons use this method to release the carpal ligament. More data should be gathered before ECTR can become the standard practice of surgical release of the carpal ligament.","PeriodicalId":294120,"journal":{"name":"Proceedings of the 1996 Fifteenth Southern Biomedical Engineering Conference","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115292838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditionally, the output of the apparatus is sent to a chart recorder where the data is recorded on chart paper for later analysis. An interface has been designed in which the signals from the Harvard Apparatus are digitized and sent to a computer for display and analysis. The hardware design consists of an Analog to Digital Converter interfaced to an IBM compatible computer through a printer port. The cost of this interfacing hardware, including the printer port, is approximately thirty dollars. The software is a short program which controls the interface and allows the display of the smooth muscle contractions as a function of time on the computer screen. The program can also create a data file for future display and analysis, and can mimic the chart recorder output by printing the graph to a printer. This system has several advantages compared to using a chart recorder. The computer interfaced experiment allows for paperless data collection and display. The data may be exported to other programs (spreadsheets or graphing software) for further manipulation and analysis. Finally, it exposes the biology student to computer technology for data collection and analysis.","PeriodicalId":294120,"journal":{"name":"Proceedings of the 1996 Fifteenth Southern Biomedical Engineering Conference","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116972355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The majority of these efforts have attempted to utilize the analysis of the capsular tissues and blood serum as a measure of the release rate and behavior. To gain a better understanding of the effect of porosity on the rate of drugs released, the authors have studied the sustained delivery of steroids from a tricalcium-phosphate-lysine steroid delivery system (TCPL) in human plasma as a model for ultrastructural evaluations. A microcrystal of TCP was prepared by following the authors' standard laboratory procedures. Three different steroids (testosterone (T), progesterone (P) and estradiol (E)) were incorporated (individually) into the TCPL matrix. Each matrix contained 60 mg of steroid and the homogeneous material was compressed with a 7400 kg compression load. The total amount of steroid released was monitored spectrophotometrically. Standard sterilized technique was used throughout the entire study. At the end of 1, 2, 3, 5, 7, 14 days of incubation, the capsules were retrieved and prepared for SEM analysis. The results of this study showed that: (1) As previously documented, the TCPL devices were capable of releasing steroids at sustained levels, and the ease of delivery was found to be: P>T>E. (2) At the end of 14 days there was a remarkable increase in the size of micro and macropores observed in all experimental and control capsules. (3) Steroid-filled capsules exhibited a higher (p<0.01) mechanical strength value (78/spl plusmn/16 MPa) compared to the mechanical strength of sham control capsules (43/spl plusmn/14 MPa). The overall conclusion of this study is that the admixture of steroid with ceramic material acted as another binder and contributed tremendously to the higher mechanical strength of the capsules compared to sham controls.","PeriodicalId":294120,"journal":{"name":"Proceedings of the 1996 Fifteenth Southern Biomedical Engineering Conference","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125281516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This gives the image its \"see through\" character. However, portions of a transparent image can be considered non-transparent if no superimposed structures are present. By defining a new type of pixel uniqueness, which the authors call \"pattern uniqueness\", the nontransparent portions of transparent images can be identified, and either removed to clarify the adjacent image features or used as templates to find and separate superimposed structures. Several adjustable criteria were defined in order to optimize the algorithm's performance: main parameters include two types of pattern similarity and minimum pattern cohesiveness. Simulated stereo image lines were processed by the algorithm with various parameter settings. An analysis of variance determined the influence of parameter alteration on algorithmic performance. It was found that the matching similarity, cohesiveness, and interaction between these variables were very important and could be adjusted to optimize noise tolerance and performance.","PeriodicalId":294120,"journal":{"name":"Proceedings of the 1996 Fifteenth Southern Biomedical Engineering Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128650887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
