A Preliminary Longitudinal Study Of White Matter Alteration In Cocaine Use Disorder Subjects, Liangsuo Ma, Joel L. Steinberg, Qin Wang, Joy M. Schmitz, Edward L. Boone, Ponnada A. Narayana, F. Gerard Moeller

Radiology Publications

Background

Previous diffusion tensor imaging (DTI) studies have consistently shown that subjects with cocaine use disorder (CocUD) had altered white matter microstructure in the corpus callosum. It is believed that these alterations are due to preexisting factors, chronic cocaine use, or both. However, there is no published longitudinal DTI study on human cocaine users yet which could shed light on the relationship between cocaine use and DTI findings.

Methods

This study used a longitudinal design and DTI to test if the white matter microstructure shows quicker alteration in CocUD subjects than controls. DTI data were acquired from eleven CocUD subjects …

A Randomized Prospective Long-Term (> 1 Year) Clinical Trial Comparing The Efficacy And Safety Of Radiofrequency Ablation To 980nm Laser Ablation Of The Great Saphenous Vein, Malcolm Sydnor, John Mavropoulos, Natalia Slobodnik, Luke Wolfe, Brian Strife, Daniel Komorowski

Radiology Publications

Purpose

To compare the short- and long-term (>1 year) efficacy and safety of radiofrequency ablation (ClosureFAST™) versus endovenous laser ablation (980 nm diode laser) for the treatment of superficial venous insufficiency of the great saphenous vein.

Materials and methods

Two hundred patients with superficial venous insufficiency of the great saphenous vein were randomized to receive either radiofrequency ablation or endovenous laser ablation (and simultaneous adjunctive therapies for surface varicosities when appropriate). Post-treatment sonographic and clinical assessment was conducted at one week, six weeks, and six months for closure, complications, and patient satisfaction. Clinical assessment of each patient was conducted …
