  2. 1. Lumbar fusion for chronic low-back pain in isthmic spondylolisthesis

    Author : Per Ekman; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Exercise; Outcome; Long-term; interbody fusion; spinal fusion; lumbar; Adjacent segment degeneration; Isthmic spondylolisthesis; Degenerative disc disease; Chronic low back pain; predictor; prospective; pain drawing; sciatica; psychologic screening; Randomized controlled trial;

    Abstract : Manifestation of isthmic spondylolisthesis (IS), with a prevalence of 5% in the general population, varies from totally asymptomatic to severe disability. Although fusion has positive short-term effects, the long-term outcome of such treatment, as well as possible accelerated degeneration of adjacent segment discs (ASD) and its clinical significance, are unknown.

  4. 2. Fusion for chronic low back pain. Treatment effects, complications and cost-effectiveness. The Swedish lumbar spine study

    Author : Peter Fritzell; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Chronic low back pain is rarely fatal or completely cured but constitutes a considerable suffering from those afflicted by it. When conservative treatment fails, lumbar fusion may occasionally be performed in order to reduce pain and decrease disability. READ MORE

  5. 3. Clinical Electrocochleography in Menière´s disease

    Author : Kornel Sass; Lund Institutionen för kliniska vetenskaper; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intrathoracic pressure; perilymphatic fistula; pressure exposure; endolymphatic hydrops; Menière´s disease; reproducibility; specificity; sensitivity; rarefaction click; condensation click; electrocochleography; summating potential; Otorhinolaryngology; audiology; auditive system and speech; Otorinolaryngologi; audiologi; hörsel- och talorganen;

    Abstract : Electrocochleography (ECoG) is an objective method to evaluate cochlear electrophysiology. The recordings are considered to reflect the mechano-electric processes of the cochlea, and can indicate the presence of suspected endolymphatic hydrops. READ MORE

  6. 4. Sensitivity-Enhanced Raman Spectroscopy and High-Speed Fluorescence for In Situ Gas-Phase Diagnostics

    Author : Haisol Kim; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Laser; Raman Spectroscopy; Laser-Induced Fluorescence; Combustion; Pyrolysis; Gasification; Gas turbine; Fysicumarkivet A:2022:Kim;

    Abstract : In this work, combustion and thermal decomposition processes were studied employing laser-based diagnostic techniques, and the techniques were improved and demonstrated to achieve enhanced detection sensitivity. Raman spectroscopy was employed to study flames under elevated and atmospheric pressures with various fuels, such as methane, hydrogen-enriched methane, DME, ethylene, and ammonia. READ MORE
