Intraoperatively administered, tranexamic acid (TA) does not reduce bleeding in total hip replacement (THR). Therefore, its prophylactic use was attempted in the present study because this has been shown to be more effective in cardiac surgery. We investigated 40 patients undergoing THR in a prospective, randomized, double-blinded study. Twenty patients received TA given in two bolus doses of 10 m

Phobic postural vertigo is characterized by subjective imbalance and dizziness while standing or walking, despite normal values for clinical balance tests. Patients with phobic postural vertigo exhibit an increased high-frequency sway in posturographic tests. Their postural sway, however, becomes similar to the sway of healthy subjects during difficult balance tasks. Posturographic recordings of 3

Objective: To examine how well ultrasound assessed occipitoposterior (OP) position or high sagittal (HS) position in primiparous women with a prolonged first stage of labor predicts a vaginal delivery and the duration of labor. Design: Prospective observational study. Setting. Stavanger University Hospital, a secondary referral center in Norway. Population. 105 primiparous women with prolonged f

Two relatives, a 61-year-old man and the 21-year-old grandson of his sister, suffered from bilateral visual loss and were diagnosed with Leber hereditary optic neuropathy. In both cases, the diagnosis was molecularly confirmed with the 11778 mitochondrial mutation. MRI showed increased T2 signal not only in the optic nerves and chiasm but also in the optic tracts, extending to the lateral genicula

Due to increased market orientation and deregulation, welfare services in Sweden have taken on the form of market-based services. The body of research on deregulation and privatization is quite substantial regarding the implications of this kind of development. However, studies of the actual process of how choices are made are less common. This article discusses the implications of greater freedom

The paper considers a problem of minimizing the total number of labels that are necessary to realize a given set of end-to-end connections in a GMPLS transport network where traffic is handled by means of Label Switched Paths-connections established using the label switching principle. The problem is important for the networks where labels are a scarce/expensive resource, like in optical networks.

Popular Abstract in Swedish Tänk dig ett system som kan bestämma hur olika typer av luftpartiklar skadar oss när dom hamnar i våra lungor. Ett system som dessutom kan skapa luftpartiklar för dessa studier vid behov och med väl uppmätta egenskaper. Denna avhandling handlar om just ett sådant system och experiment som är viktiga för att förstå om och hur det fungerar. Systemet kallas i denna avhandlExposure to nano-sized and nanostructured aerosol particles with tailored properties are likely to increase in society. Occupational exposure to various kinds of nanostructured aerosol particles such as soot and metal aggregates already exists. To understand the adverse human health effects of these particles, there is a need for systems that can Generate a stable output of aerosol particles, Char

Glycosaminoglycan (GAG) chains anchored to core proteins form proteoglycans, widely distributed cell-surface macromolecules with multiple functions, such as regulation of growth factor and cytokine signaling, cell-cell interactions, and uptake of biomolecules. The biosynthesis of GAG can be manipulated by xylosides attached to various hydrophobic groups, and we have earlier reported that a naphtho

The authors were requested to analyse the frequency of shoulder surgery at the different orthopaedic units of Sweden and to propose national indications according to evidence in literature.(nko.se) Three main groups of shoulder disorders were studied: subacromial pain, shoulder instability and pain caused by degenerative glenohumeral pathology. About 6500 shoulders were operatively treated in Swed
