Lymphatic mapping and sentinel node biopsy has been rapidly and widely adopted by the surgical community as an oncologic equivalent elective lymphadenectomy for regional node staging in both melanoma and breast cancer. Despite being the de facto standard of care, it remains a highly unstandardized procedure surrounded by many unresolved controversies for(More)
The term acute mesenteric ischemia (AMI) is applied to a wide spectrum of bowel injury within the distribution of the superior mesenteric vessels, ranging from reversible alterations in bowel function to transmural necrosis of the bowel wall. Intensivists not only are called upon to manage this catastrophic disease but also may be faced with AMI as a(More)
An aggressive diagnostic and therapeutic approach to acute mesenteric ischemia can dramatically lower the mortality of this lethal disease. The cornerstones of this approach are the earlier and more liberal use of angiography and the use of intra-arterial infusions of vasodilators in the treatment of both nonocclusive and occlusive mesenteric ischemia.
The incidence of acute mesenteric ischemia (AMI) has increased substantially over the last few decades. Death rates of 70% to 90% have been reported for traditional methods of diagnosis and therapy. Use of an aggressive radiologic, pharmacologic and surgical approach has decreased the mortality and morbidity associated with AMI. The cornerstones of(More)
PURPOSE To evaluate the efficacy and effect on patient care of performing stereotactic core needle biopsy of more than one site in the presence of multiple breast lesions. MATERIALS AND METHODS Twenty-five patients underwent stereotactic core needle biopsy of more than one site. Histologic findings at core biopsy were correlated with mammographic(More)
The urinary excretion of leucine aminopeptidase (LAP), N-acetyl-beta-glucosaminidase (NAG), and beta 2-microglobulin was measured in 12 cancer patients receiving cis-platinum to evaluate the sensitivity of these indices for renal tubular damage. NAG and LAP excretion rose markedly in all patients, and beta 2-microglobulin rose in 11. Seven of the 9 patients(More)
The aspartate transcarbamoylase inhibitor, N-(phosphonacetyl)-L-aspartate (PALA), synergistically enhanced the cytotoxicity of a combination of 5-fluorouracil (5-FU) and interferon-alpha (IFN) against human colon cancer cell lines in vitro. To test the efficacy of this combination in the clinical setting, patients with locally advanced or advanced gastric(More)
OBJECTIVE The Montefiore Medical Center experience with women with gastrointestinal (GI) cancer was reviewed to: (1) evaluate clinical parameters in patients with Krukenberg tumor (GI cancer metastatic to the ovaries) and (2) evaluate oophorectomy in GI cancer patients. METHODS (1) Charts of all female patients admitted between 1985 and 1996 with gastric(More)
