OBJECTIVE To compare carbon 11-labeled Pittsburgh Compound B ([11C]PiB) positron emission tomography (PET) findings in patients with and without Alzheimer disease lesions in frontal cortical biopsy specimens. DESIGN Cross-sectional study of [11C]PiB PET findings in patients with or without beta-amyloid (Abeta) aggregates in frontal cortical biopsy(More)
STUDY DESIGN Systematic review. OBJECTIVE To define preoperative factors predicting clinical outcome after lumbar spinal stenosis (LSS) surgery. SUMMARY OF BACKGROUND DATA LSS is the most common reason requiring lumbar spine surgery in adults older than 65 years. There are no published systematic reviews on this topic. METHODS A literature search was(More)
OBJECTIVE Amyloid-β(Aβ) aggregates are presumed to be found in the brain at an early stage of Alzheimer's disease (AD) but have seldom been assessed by brain biopsy during life in often elderly patients. METHODS Between 1991 and 2006 we evaluated 468 patients with suspected normal pressure hydrocephalus with intraventricular pressure monitoring and a(More)
Low-density lipoprotein (LDL) uptake in gliomas was studied to find out if LDL has potential as a drug carrier of boron, especially for boron neutron capture therapy. Single photon emission tomography (SPET) was performed 2 h and 20 h after intravenous injection of autologous 99mTc-labelled LDL in four patients with untreated and five patients with(More)
OBJECTIVE To evaluate whether patients acquired normal physical function after cervical disk prolapse and surgery compared with healthy matched controls. DESIGN Cross-sectional study. SETTING Hospital in central Finland. PARTICIPANTS Fifty-three patients with cervical diskectomy and 53 healthy matched controls. INTERVENTIONS Not applicable. MAIN(More)
Normal pressure hydrocephalus (NPH) can be alleviated by cerebrospinal fluid shunting but the differential diagnosis and patient selection are challenging. Intraventricular intracranial pressure monitoring as part of the diagnostic workup as well as shunting enable to obtain cortical brain biopsies to detect amyloid-β (Aβ) and hyperphosphorylated tau (HPτ),(More)
The objective of this observational prospective study was to investigate the effect of depression on short-term outcome after lumbar spinal stenosis (LSS) surgery. Surgery was performed on 99 patients with clinically and radiologically defined LSS, representing ordinary LSS patients treated at the secondary care level. They completed questionnaires before(More)
BACKGROUND Idiopathic normal pressure hydrocephalus (iNPH) causes cognitive decline that can be alleviated by shunting, but long-term outcome studies are scarce. OBJECTIVE To elucidate the long-term cognitive condition of shunt-responsive iNPH patients. METHODS The follow-up data (Kuopio University Hospital NPH Registry) of 146 patients diagnosed with(More)
BACKGROUND The significance of amyloid precursor protein (APP) and neuroinflammation in idiopathic normal pressure hydrocephalus (iNPH) and Alzheimer's disease (AD) is unknown. OBJECTIVE To investigate the role of soluble APP (sAPP) and amyloid beta (Aβ) isoforms, proinflammatory cytokines, and biomarkers of neuronal damage in the cerebrospinal fluid(More)
BACKGROUND Differential diagnosis of ventricular enlargement with normal pressure hydrocephalus (NPH) related symptoms is challenging. Patients with enlarged ventricles often manifest cognitive deterioration but their long-term outcome is not well known. OBJECTIVES We aim to evaluate long-term cognitive outcome in patients with enlarged ventricles and(More)
