The clinicopathologic characteristics and the expression of apomucin (MUC) in intrahepatic cholangiocarcinoma (ICC) with respect to gross morphology have not been comprehensively examined. ⋯ It is apparent that the IG type of ICC should be distinguished from the other types of ICC because a favorable prognosis can be expected after complete surgical resection.

Comparative Study
A cost and outcomes comparison of a novel integrated pediatric air and ground transportation system.
The purpose of this study is to compare air transportation of critically ill pediatric patients with a mixed air-ground transportation system by evaluating timeliness, safety, and cost. The setting was a tertiary care "hub" center with three outlying-referral "spoke" facilities. ⋯ We have demonstrated that a "hub-and-spoke" ground transportation system supplements air transportation in a safe, timely, and cost-effective manner.

Portal versus systemic drainage of small bowel allografts: comparative assessment of survival, function, rejection, and bacterial translocation.
Portal venous drainage of small bowel grafts is theoretically more physiologic than systemic drainage, but is technically more demanding. Comparisons in animal models have not demonstrated a clear advantage of one technique over the other, but clinical data are lacking. ⋯ Systemic venous drainage of small bowel transplants is a dependable technique, associated with similar results as portal venous drainage, in terms of overall mortality, morbidity, rejection, function, and patient and graft survival. But attention should be paid to an impaired clearance of intestinal bacterial translocation after systemic drainage.

Comparative evaluation of duplex-derived parameters in patients with chronic venous insufficiency: correlation with clinical manifestations.
Quantification of venous reflux is still a matter of debate. Our goal was to compare the duplex-derived parameters between patients with early and advanced chronic venous insufficiency (CVI), and to determine indicative parameters reflecting the progression of CVI. ⋯ Superficial venous insufficiency might play a major role in the development of advanced CVI. The peak reflux velocity and peak reflux volume improve discrimination power between early-stage and advanced CVI.
