Measurements were done to determine the plasma concentrations of galanthamine and two of its metabolites, as well as the corresponding inhibition of acetylcholinesterase activity in erythrocytes after applying 5 and 10 mg galanthamine hydrobromide as a constant-rate intravenous infusion for 30 minutes and single oral doses of 10 mg in eight healthy male(More)
Galanthamine was determined in plasma and tissue extracts of mice, after the application of 4, 6 and 8 mg/kg (i.v.), by reverse phase HPLC, with fluorescence detection. A biexponential decline of concentrations in plasma, with a terminal half-life of 43.3 min, was observed after the dose of 4 mg/kg. The volume of distribution (Vss) of 2.17 l/kg was similar(More)
Galanthamine, physostigmine and 9-amino-1,2,3,4-tetrahydroacridine (tacrine) were evaluated as inhibitors of human acetylcholinesterase activity from samples of postmortem human brain, fresh brain cortex biopsies and human erythrocytes. Acetylcholinesterase activity was most effectively inhibited in all tissues by physostigmine, followed by tacrine and(More)
BACKGROUND Autologous breast reconstruction timing continues to be controversial. The purpose of this study was to examine delayed autologous breast reconstruction at a center favouring immediate reconstruction to better understand factors driving the decision to delay reconstruction. METHODS We performed a retrospective cohort study of all free(More)
BACKGROUND Panniculectomy (PAN) during ventral hernia repair (VHR) can be a challenging procedure associated with added risk. We utilized the ACS-NSQIP datasets to generate a risk model of morbidity following these combined interventions. METHODS The 2005-2012 ACS-NSQIP databases were queried to identify all patients undergoing VHR-PAN. Multivariate(More)
Certain patients who initiate expander/implant (E/I) reconstruction following mastectomy may require radiation therapy (XRT). XRT may be delivered during the tissue expander (TE) expansion process or after exchange for a permanent implant (PI). We studied a series of women treated with E/I reconstruction and XRT to determine whether there is a difference in(More)
BACKGROUND Selective estrogen-receptor modulators and aromatase inhibitors have become ubiquitous in the treatment of breast cancer. However, hormone therapy is a well-established thromboembolic risk factor. The purpose of this study is two-fold: (1) to further evaluate tamoxifen as a potential thrombotic risk factor and (2) to evaluate use of aromatase(More)
BACKGROUND Ventral hernias are a common, challenging, and expensive problem for both the general and reconstructive surgeons; therefore, the aim of this study is to critically assess perioperative factors related to cost in abdominal wall reconstructions (AWR). METHODS A retrospective review of AWR patients from 2007 and 2012 was performed. Analysis of(More)
BACKGROUND Although hernia repair with mesh can be successful, prophylactic mesh augmentation (PMA) represents a potentially useful preventative technique to mitigate incisional hernia risk in select high-risk patients. The efficacy, cost-benefit, and societal value of such an intervention are not known. The aim of this study was to determine the(More)
