Aims: Cervical radiculopathy is a significant cause of pain and morbidity. For patients with severe and poorly controlled symptoms who may not be candidates for surgical management, treatment with transforaminal epidural steroid injections (CTFESI) has gained widespread acceptance. However, a paucity of high-quality evidence supporting their use balanced against perceived high risks of the procedure potentially undermines the confidence of clinicians who use the technique.

Indeed, symbionts have a dual niche composed of traits of their individual hosts and the abiotic environment external to the host, and often combine active dispersal at finer scales with host-mediated dispersal at broader scales. The biotic complexity in the determinants of species distribution and abundance should be even more pronounced for hyper symbionts (symbionts of other symbionts).

- A new three-dimensional method was developed to detect differences in scleral curvature using topography data from the eyes, ensuring the results weren't affected by common edge artefacts.
- The study analyzed data from 88 participants with varying demographics, processing the information using custom MATLAB software, first on raw data and then again after removing noise.
- Results showed significant differences in scleral elevation between the right and left eyes, with the most asymmetry observed in the nasal direction, indicating that the method could effectively highlight scleral asymmetry.
Kyphoplasty Augmentation in Thoracolumbar Spine - Clinical Outcomes after 2 Years.
Acta Chir Orthop Traumatol Cech
November 2019
PURPOSE OF THE STUDY With the ageing of population the vertebral insufficiency fractures are increasing in number and occur ever more frequently. Symptomatic relief is often difficult to achieve by non-operative treatment. The aim of this study was to determine the level of pain relief and functional outcomes in patients who failed initial non-operative treatment and, because of persisting or growing symptoms, underwent kyphoplasty.

- A novel lens design method was developed to reduce residual astigmatism in non-orthogonal astigmatic eyes using an optimized light ray-tracing algorithm, moving beyond conventional methods.
- Three sets of refraction trial lenses were created with controlled angles between power axes and varying cylindrical power to assess their performance on astigmatic eyes through computer simulations.
- Clinical trials on three patients with irregular astigmatism demonstrated significant improvements in vision correction with non-orthogonal lenses compared to traditional orthogonal lenses, highlighting a better approach for managing non-orthogonal astigmatism in eye care.
