conclusions in this study, we found that in spite of previous beliefs, discopathies were not common etiologies of lbp. thus, even in patients with proven ldh by imaging studies, the physician should perform a thorough evaluation for other causes of lbp to avoid unnecessary lumbar surgeries. results in our study, among 1250 patients with proven ldh by mri, 500 patients (40%) had chronic lbp and ...

STUDY DESIGN Intradiscal pressure was measured after percutaneous disc decompression by nucleoplasty in human cadavers with different degrees of disc degeneration. OBJECTIVES To assess intradiscal pressure change after disc decompression, and to analyze the influence of degeneration on the intradiscal pressure change. SUMMARY OF BACKGROUND DATA Partial removal of the nucleus has been shown ...

The utilization of agricultural machinery represents the main aspect contributing to total energy input in system. trials were achieved using five tractor speeds(3.6, 5.4, 7.2, 9.0 and 10.8 km/hr) tillage depths(10, 15, 20, 25 30 cm) determine implement speed at different depths for 3-bottom disc plough, spring tine cultivator offset harrow on a clay loam soil. design experiment used two factor...

AIMS To determine if 'Defocus Incorporated Soft Contact' (DISC) lens wear slows childhood myopia progression. METHODS A 2-year double-blind randomised controlled trial was carried out in 221 children aged 8-13 years, with myopia between -1.00 and -5.00 Dioptres (D) and astigmatism ≤1.00 D. Subjects were randomly assigned to the DISC (n=111) or single vision (SV; n=110) contact lens group. DIS...

We present a chemical abundance analysis on the basis of high signal-tonoise and high resolution spectra for 12 stars of our newly defined sample. The selection criterion for the stars of this sample was their position in the ‘RVTauri’ box in the [12] − [25], [25] − [60] two-colour diagram. An additional requisite was the presence of a near-IR excess. We found that the photospheres of nine star...

OBJECTIVE Percutaneous techniques are rapidly replacing traditional open surgery. This is a randomized controlled trial study of clinical outcomes of Percutaneous Plasma Disc Coagulation Therapy (PDCT) in patients with HLD(herniated lumbar disc) as a new percutaneous access in comparison with Automated Percutaneous Lumbar Discectomy (APLD) in its clinical application and usefulness as a reliabl...

introduction: this study is aimed to compare phenotypic test methods and determine antibiotic susceptibility pattern of ampc beta-lactamase producing uropathogenic escherichia coli and klebsiella pneumoniae in clinical isolates. method: e. coli and k. pneumoniae were identified by standard microbiological procedures. screening of ampc beta-lactamase production was done by using cefoxitin disc (...

High resolution spectra of 5 candidate metal-weak thick-disc stars suggested by Beers & Sommer-Larsen (1995) are analyzed to determine their chemical abundances. The low abundance of all the objects has been confirmed with metallicity reaching [Fe/H]= −2.9. However, for three objects, the astrometric data from the Hipparcos catalogue suggests they are true halo members. The remaining two, for w...

Medical records of 363 patients who had a diagnosis of lumbar disc disease and were managed by a posterior approach lumbar discectomy over a 7 year period were reviewed: 33 patients had a preoperative diagnosis of diabetes, an incidence in this patient population of 9.1%. The results for these 33 patients who had a diagnosis of diabetes mellitus were compared with those of 33 age and sex matche...

Glaucoma is a pathological condition, progressive neurodegeneration of the optic nerve, which causes vision loss. The damage to the optic nerve occurs due to the increase in pressure within the eye. Glaucoma is evaluated by monitoring intra ocular pressure (IOP), visual field and the optic disc appearance (cup-to-disc ratio). Cup-to disc ratio (CDR) is normally a time invariant feature. Therefo...
