The mean intensity and the displacement from the initially given propagation direction of the optical beam passed through the shock wave have been calculated. It has been shown that the spatial inhomogeneity of the refractive index of air caused by the shock wave arising in supersonic flow flowing a conical body can cause the focusing of the beam and strong anisotropic distortions of the intensity distribution in its cross section. The angular displacement of the optical beam from the initially given propagation direction owing to the shock wave depends only on the height above the Earth's surface at which the shock wave is formed. As the height increases, the influence of the shock wave on the optical beam propagating through it decreases.

Objective: This study aims to quantitatively compare the effects of standard needle irrigation (SNI), passive ultrasonic irrigation (PUI), EDDY, photon-initiated photoacoustic streaming (PIPS), and shock wave-enhanced emission photoacoustic streaming (SWEEPS) on the apical extrusion of irrigation solutions in teeth with severe canal curvature.

Materials And Methods: Seventy-five teeth with a single root and canal, and curvature angles ranging from 20° to 40°, were selected for this study. Root canal curvatures were measured from buccolingual and mesiodistal radiographs using ImageJ software (version 1.

This Umbrella Review aims to gather high-quality evidence on urolithiasis outcomes and complications, comparing extracorporeal shockwave lithotripsy (ESWL), ureteroscopic lithotripsy (URSL), and retrograde intrarenal surgery (RIRS). We incorporated systematic reviews, some containing meta-analyses, into two separate reports, focusing on quantitative and qualitative results. Additionally, when data permitted, a secondary meta-analysis was conducted using final effect estimates from multiple meta-analyses.

Background Morton's neuroma is a common cause of forefoot pain, typically occurring in the third metatarsal space and characterized by symptomatic nerve compression. This condition often leads to significant functional impairment, affecting weight-bearing activities and limiting appropriate footwear due to pain and discomfort. Objective This study aims to evaluate the outcomes of conservative interventional treatment for Morton's neuroma, specifically focusing on corticosteroid injections.
