BACKGROUND Metastasis of unknown origin (MUO) is a diagnostic challenge in clinical practice even with the state of current advanced diagnostic technology. To evaluate the value of autopsy in determining the primary site of MUO, this study reviewed the Hamilton experience-over the last 20 years-with patients autopsied with clinical diagnosis of MUO.

CONTEXT Undifferentiated (anaplastic) carcinoma of the pancreas with osteoclast-like giant cells is exceedingly rare. The prognosis of undifferentiated carcinoma is worse than that of poorly differentiated ductal adenocarcinoma of the pancreas; however, undifferentiated carcinoma with osteoclast-like giant cells might have a more favorable prognosis.

Multicenter clinical trials are often larger and more complex than other methods of clinical inquiry. They tend to involve a number of research or clinical centers and several formal committees. In many of these trials a coordinating center is one of the participating organizational units. This article describes one such coordinating center, that of the(More)
Oxytocin is a commonly used uterotonic that can cause significant and even fatal hypotension, particularly when given as a bolus. The resulting hypotension can be produced by a decrease in systemic vascular resistance or cardiac output through a decrease in venous return. Parturients with normal volume status, heart valves and pulmonary vasculature most(More)
The influence of ageing on the fracture mechanics of cortical bone tissue is well documented, though little is known about if and how related material properties are further affected in two of the most prominent musculoskeletal diseases, osteoporosis and osteoarthritis (OA). The femoral neck, in close proximity to the most pertinent osteoporotic fracture(More)
The Sellick maneuver or cricoid pressure is an effective means of preventing passive aspiration of gastric contents. Recent studies recommend a pressure of 20 newtons (N) when the patient is awake, increasing to 30-40 N with unconsciousness. This study was proposed to determine whether with education and practice, anesthesia providers and assistants could(More)
