Traumatic brain injury (TBI) is a major cause of morbidity and mortality in Western countries. Effective management planning for these patients requires knowledge of TBI epidemiology. The purpose of this study was to describe and analyze the development of TBI mortality in the Nordic countries during the period 1987-2001. Data on TBI deaths were retrieved(More)
The cervical collar has been routinely used for trauma patients for more than 30 years and is a hallmark of state-of-the-art prehospital trauma care. However, the existing evidence for this practice is limited: Randomized, controlled trials are largely missing, and there are uncertain effects on mortality, neurological injury, and spinal stability. Even(More)
Brain metastasis is associated with a particular poor prognosis. Novel insight into the brain metastatic process is therefore warranted. Several preclinical models of brain tumor metastasis have been developed during the last 60 years, and they have in part revealed some of the mechanisms underlying the metastatic process. This review discusses mechanisms(More)
Our goal was to develop strategies to quantify the accumulation of model therapeutics in small brain metastases using multimodal imaging, in order to enhance the potential for successful treatment. Human melanoma cells were injected into the left cardiac ventricle of immunodeficient mice. Bioluminescent, MR and PET imaging were applied to evaluate the(More)
BACKGROUND Traumatic brain injury (TBI) is the major cause of death among young adults in western countries. In the context of a joint Nordic initiative regarding future management of patients with severe TBI, it was of interest to look into the magnitude of the problem and the most recent developments. MATERIAL AND METHODS We have conducted a survey of(More)
Oligodendroglioma poses a biological conundrum for malignant adult human gliomas: it is a tumor type that is universally incurable for patients, and yet, only a few of the human tumors have been established as cell populations in vitro or as intracranial xenografts in vivo. Their survival, thus, may emerge only within a specific environmental context. To(More)
Surgery for chronic subdural hematoma (CSDH) is performed to relieve brain displacement and high intracranial pressure (ICP). However, the intraoperative impression is often that the pressure inside the CSDH is low, despite marked clinical symptoms. We wanted to quantify the CSDH pressure and relate this to radiological and clinical characteristics. This(More)
OBJECTIVE The aim of this study is to map and evaluate the available resources and the premises of traumatic head injury management in the Nordic countries, before the implementation of a Nordic adaption of the Brain Trauma Foundation guidelines for prehospital management. METHODS The study is a synthesis of two cross-sectional surveys. Questionnaires(More)
Biologic and therapeutic advances in melanoma brain metastasis are hampered by the paucity of reproducible and predictive animal models. In this work, we developed a robust model of brain metastasis that empowers quantitative tracking of cellular dissemination and tumor progression. Human melanoma cells labeled with superparamagnetic iron oxide(More)
OBJECTIVES We have previously determined the incidence and prevalence of idiopathic normal pressure hydrocephalus (iNPH) in the county of Vestfold in Norway. This study aimed at determining the incidence of surgeries for iNPH. MATERIALS AND METHODS Information about age, sex, operation year and operation type was collected retrospectively for all patients(More)
