Introduction: Sciatic pain is a frequent clinical problem. An important manifestation of the degenerative lumbar spine is pain radiating to the legs, also called sciatica. The straight-leg-raising (SLR) test is one of the most significant signs for making a clinical diagnosis of lumbar disc herniation [1]. Our previous study showed that intraradicular blood flow and electrophysiological values ...

background & aim: low back pain is the most debilitating condition, and can lead to decreased physical function, compromised quality of life, and psychological distress. several studies have been conducted to recognize the risk factors of low back pain, but despite of strong relationship between obesity and low back pain, the underlying mechanisms are unclear. the aim of this study was to evalu...

Background: Once identified as Staphylococcus aureus, it is imperative to understand their methicillin resistance status for institution of appropriate therapy. Conventional disc diffusion tests may not accurately identify MRSA strains and may not be in concordance with PCR results. Objectives: Relative abilities of phenotypic and molecular methods to detect MRSA strains was evaluated to unders...

Between 1994 and 1996 we detected 28 out of 7054 (0.4%) clinical isolates of Escherichia coli with abnormal or reduced inhibition diameters to co-amoxiclav and ceftazidime in a disc diffusion test. The increased MIC of ceftazidime (1-32 mg/L) and the effect of synergy between this antibiotic and co-amoxiclav according to the disc diffusion test suggest the presence of an extended-spectrum beta-...

Discography is an exquisitely sensitive but not specific diagnostic test for the diagnosis of discogenic low-back pain. The restriction of the definition of a positive discographic study to one that elicits concordant pain from a morphologically abnormal disc improves the definition's accuracy. Fusion surgery based on discography alone, however, is not reliably associated with clinical success....

Several studies have been conducted to recognize the risk factors of low back pain, but despite of strong relationship between obesity and low back pain, the underlying mechanisms are unclear.

BACKGROUND The goal of this study was to identify the in vivo effects in patients with hyposalivation of a novel slowly dissolving adhering test disc upon on enamel remineralization, oral biofilm, salivary production, pH and buffering, gingival health, and on self-evaluation of oral well-being. METHODS Five subjects with xerostomia wore custom made retainers carrying 5 demineralized enamel ch...

This study was performed to standardize a dentin barrier test with the substitute and evaluate the cytotoxicity of one-step self-etching bonding agents. Each of the natural bovine dentin and polyurethane discs were 500-μm thick and were tested using a perfusion device. Following the treatment with 0.05% phenol on the natural bovine disc or three kinds of polyurethane discs-30, 40, and 50 pcf (p...
