When the original TASH-Score was applied onto the 2004-2007 TR-DGU database, a slight increase in discrimination was observed while precision was considerably lower. The predicted rate for MT within the development dataset was 13·9% while the observed incidence was 14·1%. In contrast, the predicted rate for MT within the revalidation dataset was 11·7%, while the observed rate was 8·4%. The logistic function to calculate MT probability was modified, and the TASH-Score was again evaluated against the most recent TR-DGU 2004-2007 database. The high performance of the score was not only restored but enhanced reflected by an increased ROC/AUC of 0·905. The score can be calculated quickly upon arrival of the patient in the emergency department and may be supportive to correct coagulopathy, to activate logistics and for research.
Perineural catheters are increasingly used worldwide for the treatment of postoperative pain in orthopedics. Long-term complications associated with the placement of a perineural catheter remain largely unstudied. We investigated the efficacy and the acute and late complications associated with the continuous popliteal nerve block. One-thousand-one patients undergoing elective surgery of the ankle or foot and scheduled to have a continuous popliteal nerve block were prospectively evaluated. All patients received an initial bolus of 40 mL ropivacaine 0.5% through the catheter. A continuous infusion of ropivacaine 0.3% initiated 6 h after the initial bolus was administered for the first 24 h and then decreased to ropivacaine 0.2% until the end of the study period. The success rate and acute complications were recorded. The overall success rate was 97.5%. The highest success rate was associated with foot inversion. Acute complications consisted of paresthesias during nerve localization (0.5%), pain during local anesthetic application (0.8%), and blood aspiration (0.4%). No central nervous system toxicity or cardiotoxicity occurred. Late complications were checked at 10 days and 3 mo after surgery. These included two cases of inflammation at the puncture site. No infection or neuropathy was observed. The use of continuous popliteal nerve block for ankle or foot surgery is associated with frequent success and few acute and late complications.
Vertical reduction mammaplasty using a superomedial pedicle is a well-accepted technique giving good results in mild to moderate breast hypertrophy. We describe modifications of the vertical reduction technique to achieve safe reductions even for very large breasts and minimize unsightly scarring, skin necrosis and poor shape. Over the past 4 years, 162 patients have undergone bilateral breast reduction using the vertical mammaplasty technique with a superomedial dermoglandular pedicle. We present a retrospective study of 23 cases of gigantomastia (reductions over 1100g) who underwent bilateral reduction mammaplasty, using our technique. The mean age was 49 years, BMIs ranged from 28 to 52 kg/m. The mean suprasternal notch-to-nipple distance was 40.5 cm on the right and 41.4 cm on the left. The average resection weight per breast was 1303 g on the right, and 1245 g on the left side. The suprasternal notch-to-nipple distance was reduced by between 13.2 and 36.0 cm (mean, 16.1 cm). Mean follow-up was 14 months. We observed a superficial infection in 2 patients, a deep hematoma in one patient, partial necrosis of the nipple-areola complex in 1, and 2 patients needed correction surgery due to dog-ear formation. By using the described modifications, the nipple and areola were safely transposed on a superomedial dermoglandular pedicle producing good breast shapes, while scarring and complications in vertical reduction mammaplasty for oversized breasts were effectively minimized.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
