Retiform hemangioendothelioma was differentiated from low-grade cutaneous angiosarcoma by Calonje et al. [1] in 1994; retiform hemangioendothelioma is a very rare tumor of the blood vessels, with less than 30 cases(More)
BACKGROUND Temporalis muscle transfer produces prompt surgical results with a one-stage operation in facial palsy patients. The orthodromic method is surgically simple, and the vector of muscle action is similar to the temporalis muscle action direction. This article describes transferring temporalis muscle insertion to reconstruct incomplete facial nerve(More)
BACKGROUND The aim of this study was to investigate whether a small dose of midazolam and lessening the propofol dosage could prevent cardiovascular change at tracheal intubation for induction in aged patients. METHODS Eighty patients over 65 years (ASA physical status 1, 2) scheduled for elective surgery received general anesthesia with remifentanil and(More)
A DPCM system employing a median predictor, which is c:illcd tlic predictive mcdi;in-DPCM(PM~DPCM), is proposed. An interesting property that in PM-DPCM transmission noise is often isolated and not propagated ovci-tlic reconstructed signals i s ohser\,cd ancl is analy/.cd dctci-ministically and statistically. In order to examine tlic pcrlomiancc(More)
BACKGROUND Restoring orbital volume in large blowout fractures is still a technically challenge to the orbital surgeon. In this study, we restored the orbital wall using the combination of transorbital and transnasal approach with additional supports from the paranasal sinuses, and we compared the surgical outcome to that of a conventional transorbital(More)
BACKGROUND Bioabsorbable plates and screws are commonly used to reduce maxillofacial bones, particularly in pediatric patients because they degrade completely without complications after bone healing. In this study, we encountered eight cases of a delayed foreign body reaction after surgical fixation with bioabsorbable plates and screws. METHODS A total(More)
We propose an algorithm to perform jointly the azimuthal direction-of-arrival (DOA) estimation and multi-user detection (MUD) of signals that impinge an array of antennas. We treat DOA estimation and MUD as an inverse problem of finding specific sets of parameters, viz., {/spl phi//sub i/} and the corresponding {s/sub i/}. We reformulate this nonlinear(More)
