Comparative Study
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.

Experience using radiofrequency ablation (RFA) for treating unresectable hepatic malignancies is expanding, with promising outcomes and fewer complications compared with cryotherapy. ⋯ In contrast to previous reports using cryotherapy, systemic inflammatory responses as measured by increased cytokines were not observed after RFA. The cryotherapy-induced "cryoshock" phenomenon was not observed in patients undergoing RFA in our study. We conclude that RFA ablation is fundamentally different than cryotherapy and apparently does not stimulate Kupffer and other hepatic macrophages to produce proinflammatory cytokines.

Orbital fractures are associated with ocular and periocular injuries. The role of the ophthalmologist in the evaluation and management of facial trauma, including orbital fractures, has not been clearly defined. The purpose of this study is to identify and characterize ocular and periocular injuries associated with orbital fractures to define the role of the ophthalmologist in the management of facial trauma. ⋯ Facial trauma and orbital fractures are associated with significant ocular and periocular injuries, the minority of which require immediate evaluation and treatment by an ophthalmologist. These results differ from those previously reported.
