Pancreatic fistula is a major source of morbidity after distal pancreatectomy (DP). We reviewed 462 consecutive patients undergoing DP to determine if the method of stump closure impacted fistula rates. A retrospective review of clinicopatologic variables of patients who underwent DP between February 1994 and February 2008 was performed. The International(More)
In a cohort of gay men responding to the threat of acquired immunodeficiency syndrome (AIDS), dispositional optimism was associated with less distress, less avoidant coping, positive attitudes as a coping strategy, and fewer AIDS-related concerns. Men who knew they were seropositive for human immunodeficiency virus (HIV) were significantly more optimistic(More)
PURPOSE Thoracoscopic lobectomy for congenital cystic lung lesions is an accepted technique in pediatric surgery. Since an increasing number of these lesions are detected prenatally, the safety and efficacy of infant resections have been questioned. We reviewed our experience over a 10-year period to evaluate early resection of these lesions. METHODS From(More)
BACKGROUND Transfemoral carotid artery stenting (CAS) has been associated with a high incidence of embolic phenomena and silent brain infarction. The goal of this study was to compare the incidence of new ischemic cerebral lesions on diffusion-perfusion magnetic resonance imaging (MRI) sequences after transcervical CAS performed with carotid flow reversal(More)
Electrophysiological properties of spiking neurons receiving complex stimuli perturbed by noise are investigated. A semi-analytical estimate of firing probabilities and subthreshold behavior of the stochastic system can be made in terms of the solution of a purely deterministic system. The method comes from an approximation for the distribution function and(More)
The objective of this study was to compare the treatment plan designed on the basis of preoperative duplex scanning evaluation of the critical limb ischemia with the treatment plan finally carried out, after assessing the findings obtained during surgical or endovascular treatment. Over a period of 51 months a preoperative duplex scanning study was carried(More)
BACKGROUND The introduction of fluorescence-guided resection allows a better identification of tumor tissue and its more radical resection. We describe our experience with a modified exoscope to detect 5 ALA-induced fluorescence in neuronavigation-guided brain surgery or biopsy of malignant brain tumors. METHODS Thirty-eight patients with a suspected(More)
This phase II trial evaluated the efficacy and safety of docetaxel 85 mg/m2 (day 1) and cisplatin 80 mg/m2 (administered as 40 mg/m2 doses each on days 1 and 2) every 3 weeks as first-line treatment of patients with advanced non-small cell lung cancer (NSCLC). Forty-two NSCLC patients were enrolled, most of them with stage IV disease (74%). A total of 195(More)
An increase in cases of death from overdose and abuse from fentanyl or sufentanil is being encountered by the Bexar County Forensic Science Center in San Antonio, Texas. These drugs have been abused almost solely by health care professionals. The fentanyl derivatives cannot currently be detected by routine laboratory drug-screening programs. Forensic(More)
A case of death from self-injection of fentanyl and a method for its detection in autopsy specimens are reported. Fentanyl was measured by extraction of biological samples with ethyl acetate, partitioning into 0.1N HCl, then reextracting into ethyl acetate after alkalinization of the acid phase. After reducing to a residue, the fentanyl was measured by(More)
