Low back pain (LBP) is currently the most prevalent and costly musculoskeletal problem in modern societies. Screening instruments for the identification of prognostic factors in LBP may help to identify patients with an unfavourable outcome. In this systematic review screening instruments published between 1970 and 2007 were identified by a literature(More)
STUDY DESIGN Retrospective case-referent study. OBJECTIVE To assess whether the new sedimentation sign discriminates between nonspecific low back pain (LBP) and symptomatic lumbar spinal stenosis (LSS). SUMMARY OF BACKGROUND DATA In the diagnosis of LSS, radiologic findings do not always correlate with clinical symptoms, and additional diagnostic signs(More)
Protein kinase CK2, a vital, pleiotropic and highly conserved serine/threonine phosphotransferase is involved in transcription-directed signaling, gene control and cell cycle regulation and is suspected to play a role in global processes. Searching for these global roles, we analyzed the involvement of CK2 in gene expression at cell cycle entry by using(More)
The sedimentation sign (SedSign) has been shown to discriminate well between selected patients with and without lumbar spinal stenosis (LSS). The purpose of this study was to compare the pressure values associated with LSS versus non-LSS and discuss whether a positive SedSign may be related to increased epidural pressure at the level of the stenosis. We(More)
BACKGROUND CONTEXT The nerve root sedimentation sign in transverse magnetic resonance imaging has been shown to discriminate well between selected patients with and without lumbar spinal stenosis (LSS), but the performance of this new test, when used in a broader patient population, is not yet known. PURPOSE To evaluate the clinical performance of the(More)
Zac is a C2H2 zinc finger protein, which regulates apoptosis and cell cycle arrest through DNA binding and transactivation. During tumorigenesis and in response to mitogenic activation, Zac gene expression is down-regulated in a methylation-sensitive manner. As yet, no target genes have been identified that could explain the potent antiproliferative(More)
Lumbar spinal stenosis is a frequent indication for spinal surgery. The predictive quality of treadmill testing and MRI for diagnostic verification is not yet clearly defined. Aim of the current study was to assess correlations between treadmill testing and MRI findings in the lumbar spine. Twenty-five patients with lumbar spinal stenosis were prospectively(More)
OBJECTIVE Occupational low back pain (LBP) is considered to be the most expensive form of work disability, with the socioeconomic costs of persistent LBP exceeding the costs of acute and subacute LBP by far. This makes the early identification of patients at risk of developing persistent LBP essential, especially in working populations. The aim of the study(More)
Lumbar spinal stenosis is a common degenerative disorder of the spine in elderly patients that can be effectively treated with decompression surgery in some patients. Radiological findings in the diagnostic work-up of the patients do not always correlate well with clinical symptoms, and guidance about when to proceed to surgery is inconsistent. The recently(More)
The yeast one-hybrid system (1H-system) is applied to studies of transcription-linked DNA-protein interactions under in vivo conditions detected by reporter gene expression. By use of a variant of green fluorescent protein (GFP) as a reporter, the new 1H-system generation represents a time- and work-saving alternative to the established HIS3/lacZ-based(More)
