Study design The University of Illinois Medical Center at Chicago dischar ge database was used to identify 135 women from 1999 through 2001 whose disease was coded as having preeclampsia or eclampsia. With American College of Obstetri cs and Gynecology criteria as the gold standard, the diagnosis that was determin ed through chart review was compared with the International Classification of Di seases-9th revision code that was present in the discharge database. Patients w ere classified as true cases if the International Classification of Diseases-9t h revision code matched the American College of Obstetricians and Gynecologists diagnosis; the positive predictive value of the code was then calculated. Result s The overall positive predictive value for the complete sample was only 54%, b ut the positive predictive value for severe preeclampsia was 84.8%, which was h igh compared with mild preeclampsia (45.3%) and eclampsia (41.7%). Diagnostic (clinician) error was the most common reason for miscoding error. Conclusion The findings suggest that International Classification of Diseases-9th revision co des for preeclampsia/eclampsia vary greatly in their accuracy of diagnosis. Ther efore, a review of medical records is required when data are being gathered on t he incidence of preeclampsia and eclampsia.展开更多

On the basis of chemical and spectral studies especially 2D NMR including COSY, HETCOR, HOHAHA, ROESY and HMBC techniques, its structure has been established as 3-O-beta -D-glucopyranosyl-(1 -->6)-beta -D-glucopyranosyl-2 beta ,3 beta -dihydroxy-olean-12-en-23 alpha ,28-dioic acid-28-O-alpha -L-arabinopyranosyl-(1 -->3)-alpha -L-rhamnopyranosyl-(1 -->2)-beta -D-fucopyranoside.展开更多

They are placed either in the neck or groin based primarily upon the surgeon’ s preference. There is meager published in-formation available about the relative risks of these lines. This is a retrospective analysis of all the tunneled central venous catheters placed in NICU babies at a children’ s hospital over a nearly 5-year period. Single lumen Broviac catheters were used in all cases. A total of 137 catheters were placed in 126 patients. There were 88 neck lines and 49 groin lines. Age, gestational maturity, and body weight were significantly lower for babies who underwent groin line placement. There was no significant difference in the number of days the catheters were live between the 2 groups. Total complication rates and catheter infection rates were significantly higher with neck lines. The accidental removal rate was higher with neck lines but did not reach statistical significance. Broviac catheters placed in the groin of NICU babies are associated with significantly fewer complications compared with those placed in the neck.展开更多
