OBJECTIVE To examine the effect of selective preoperative biliary drainage (BD) on perioperative resuscitation, morbidity, and mortality in patients undergoing pancreaticoduodenectomy. Biliary drainage prior to pancreaticoduodenectomy remains controversial. Proponents argue that it facilitates referral to high-volume tertiary centers, while detractors(More)
BACKGROUND Noninsulinoma pancreatogenous hypoglycemia (NIPH) is a rare cause of hypoglycemia, especially affecting postbariatric surgery patients, related to excessive insulin secretion. Partial pancreatectomy controls hypoglycemia in the early postoperative period; however, multiple patients have experienced symptomatic relapse. The study goal was to(More)
OBJECTIVE To evaluate the effects of resident duty-hours restrictions on teaching faculty, patient care, and the institutional climate at a single center. METHODS An anonymous questionnaire was provided to all teaching faculty (N = 606) at a single institution from March through October 2006. The questionnaire focused on perceptions of job satisfaction,(More)
BACKGROUND Pheochromocytomas and paragangliomas are highly vascular neuroendocrine neoplasms that often secrete catecholamines. Percutaneous biopsy has been associated with life-threatening hemorrhage, hypertensive crisis, capsular disruption with tumor implantation, and death. We sought to determine the outcomes of biopsy in 20 consecutive patients. (More)
Understanding how physicians acquire and adopt new technologies for cancer diagnosis and treatment is poorly understood, yet is critical to the dissemination of evidence-based practices. Sentinel lymph node biopsy (SLNB) has recently become a standard technique for axillary staging in early breast cancer and is an ideal platform for studying medical(More)
Sentinel lymph node biopsy (SLNB) has become a standard for axillary staging for early breast cancer patients. Prior studies suggest that SLNB may be more sensitive for the identification of lymph node disease than axillary lymph node dissection (ALND). We hypothesized that SLNB use increases the incidence of node-positivity in early breast cancer patients(More)
Sentinel lymph node biopsy (SLNB) has largely replaced axillary dissection (ALND) for axillary staging in early breast cancer. However, intense pathologic evaluation is not routinely available intraoperatively; therefore, patients with SLN metastasis may require a second surgery for completion ALND. We hypothesized that a single-section approach (by either(More)
Thiazole-4-carboxamide adenine dinucleotide (TAD) analogue 7 containing a fluorine atom at the C2' arabino configuration of the adenine nucleoside moiety was found to be a potent inducer of differentiation of K562 erythroid leukemia cells. This finding prompted us to synthesize its hydrolysis-resistant methylenebis(phosphonate) and(More)
Inosine monophosphate dehydrogenase (IMPDH) controls a key metabolic step in the regulation of cell growth and differentiation. This step is the NAD-dependent oxidation of inosine 5' monophosphate (IMP) to xanthosine 5' monophosphate, the rate-limiting step in the synthesis of the guanine nucleotides. Two isoforms of IMPDH have been identified, one of which(More)
BACKGROUND Despite the recent completion of several trials of adjuvant therapy after resection for pancreatic adenocarcinoma, the absolute impact on survival and the identification of appropriate patients for treatment has remained controversial. In the current study, the authors sought to identify the impact of adjuvant therapy and factors associated with(More)
