Metastatic Mammary Carcinoma Presenting as a Large Cystic Axillary Mass: A Report of an Unusual Case.

The differential diagnosis of cystic axillary masses is broad and includes intranodal lesions. Cystic metastatic tumor deposits are rare, and have been reported in a few tumor types, most commonly in the head and neck region, but rarely described with metastatic mammary carcinoma. We report a case of a 61-year-old female who presented with a large right axillary mass.

Spontaneous colonic perforation: a rare complication of collagenous colitis.

Collagenous colitis is a clinicopathologic syndrome characterized by chronic watery diarrhea and unique histopathologic features. Spontaneous colonic perforation in the setting of collagenous colitis is a highly unusual complication, with only three cases reported in the literature to date. We present a fourth case and propose a potential pathologic mechanism for acute colonic perforation in this patient population.

Effect of obesity and decompressive laparotomy on mortality in acute pancreatitis requiring intensive care unit admission.

Background: Controversy still exists on the effect that obesity has on the morbidity and mortality in severe acute pancreatitis (SAP). The primary purpose of this study was to compare the mortality rate of obese versus nonobese patients admitted to the ICU for SAP. Secondary goals were to assess the potential risk factors for abdominal compartment syndrome (ACS) and to investigate the performance of validated scoring systems to predict ACS and in-hospital mortality.

The use of tegaserod in critically ill patients with impaired gastric motility.

Studies have shown that early enteral nutrition in critically ill patients reduces the incidence of morbidity and death. Nonetheless, intolerance to gastric enteral nutrition is common in these patients as a result of gastroparesis. The use of prokinetic agents such as metoclopramide, domperidone, cisapride, and erythromycin can improve gastric emptying, but these agents are not without deleterious adverse effects.

Ten years of breast screening in the Nova Scotia Breast Screening Program, 1991-2001. experience: use of an adaptable stereotactic device in the diagnosis of screening-detected abnormalities.

Objective: To evaluate and present 10-year outcomes of the Nova Scotia Breast Screening Program (NSBSP), a population-based screening program in the province of Nova Scotia, Canada, total population 900 000.

Setting: Organized Breast Screening Program in Nova Scotia, Canada.

Methods: Rates of participation, abnormal referrals, cancer detection rates, and benign:malignant (B:M) rates for core biopsy and surgical biopsy were calculated for asymptomatic women receiving a mammogram through the NSBSP 1991-2001.
