Recent works have shown that scaling causes the number of repeaters to grow rapidly. We demonstrate that this growth leads to massive placement perturbations that break the convergence of today’s interleaved placement and repeater insertion flows. We then present two new force models for repeaters targeted towards quadratic placement algorithms. Our experiments demonstrate the effectiveness of ...

Background and Aim: One of the weaknesses of Class II composite resin restorations is gingival microleakage which contributes to postoperative sensitivity and secondary caries. The aim was to evaluate the microleakage in Class II composite resin restorations with different thicknesses of resin-modified glass ionomer (RMGI). Materials and Methods: In this in-vitro study, standardized Class II s...

OBJECT The objective of this study was to compare the accuracy of 3 methods of ventricular catheter placement during CSF shunt operations: the freehand technique using surface anatomy, ultrasonic guidance, and stereotactic neuronavigation. METHODS This retrospective cohort study included all patients from a single institution who underwent a ventricular CSF shunting procedure in which a new v...

Responsive neurostimulation (RNS) is rapidly gaining traction as a therapy for medically refractory epilepsy. Depth electrode placement for stimulation of a deep seizure focus may be indicated after the focus has been electrophysiologically localized using depth electroencephalography (depth EEG). We describe a simple technique whereby the bony trajectories created during initial stereotactic p...

INTRODUCTION We aimed to compare the accuracy between the standard anterior technique of shoulder injection and the new superomedial technique modified from Neviaser arthroscopic portal placement. Intra-articular placement, especially at the long head of biceps (LHB) tendon, and needle depth were evaluated. METHODS Fifty-eight patients (ages 57 ± 10 years) requiring shoulder arthroscopy in th...

Introduction: Traditional artificial urinary sphincter (AUS) implantation requires the patient be placed in lithotomy, a perineal incision for cuff placement, and a inguinal incision for reservoir and pump placement. We believed AUS could also be placed more through one transverse scrotal incision (J Urol I 69:26 1, 2003). Cuffs placed in this procedure were usually 4.0 cm. Questions about the ...

This is a case report describing the ultrasound-guided placement of a peripheral intravenous catheter into the internal jugular vein of a patient with difficult vascular access. Although this technique has been described in the past, this case is novel in that the Seldinger technique was used to place the catheter. This allows for safer placement of a longer catheter (2.25″) without the need fo...
