  2. 21. Autonomic cardiac control in patients with epilepsy : spectral analysis of heart rate variability

    Author : Håkan Persson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : SUDEP; autonomic nervous system; heart rate variability; epilepsy; carbamazepine; epilepsy surgery;

    Abstract : The heart is affected by the central nervous system via sympathetic and para-sympathetic efferents from autonomic centres in the brain stem. By assessing the beat to beat variation of the RR-intervals of the heart, i.e. the heart rate variability (HRV) it is possible to separately analyse sympathetic and parasympathetic effects on the heart.

    Abstract : ConclusionsPaper I: Complications in Extracorporeal Shock Wave Lithotripsy (ESWL): A cohort study, conclusion: We conclude that there are few complications to modern ESWL treatment. 1 Hz should be used to reduce complications (p=0.025). As there is no indication that 1Hz is less effective than 1. READ MORE

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

    Abstract : If sound and noise from an engine, say a lawn mower, is to be reduced, it is of advantage to know from which part of the machine the noise is coming. An interesting medical application for localization of sound sources is optoacoustic imaging of tissue. READ MORE

  7. 25. On various protocols for direct loading of implant-supported fixed prostheses

    Author : Pär-Olov Östman; Göteborgs universitet; []
    Keywords : dental implants; immediate loading; clinical studies; radiography; implant stability; resonance frequency analysis;

    Abstract : Backgrund: Prosthetic rehabilitation of the edentulous patient with implant-supported bridges is today a routine and predictable treatment modality. The original protocol prescribed a healing period of 3 to 6 months prior to loading which means that the total treatment time can be extensive and that the patients often need to wear removable provisional prostheses during healing and treatment.
