herpes zoster is a rare cause of non-discogenic sciatica. a combination of case rarity and name similarity was nearly leading to an inopportune surgery in a 21 years old woman. the clinical presentation was completely similar to a cauda equina syndrome associated with urinary incontinence and bilateral leg involvement. concurrently, lumbosacral imaging of another patient with exactly similar na...

The SW Sex stars are a class of cataclysmic variables, originally identified because they shared a number of enigmatic properties – most notably, single-peaked emission lines instead of the double-peaked lines one would expect from their high-inclination accretion discs. We present high-time-resolution spectrophotometry of the eclipsing nova-like variables SW Sex and DW UMa, two of the founding...

localizing the optic disc (od) in retinal fundus images is of critical importance, since it is very similar to hard exudates (found in pathology) in color and brightness. because of the importance of od localization in clinical applications, many techniques have been developed. in this paper, we present the results obtained from two methods, correlation and least square, to approximate the opti...

in a retrospective study the clinical presentations, neurological findings, contrast studies, operative findings, and the follow-up results of 314 patients with disc herniation were studied over a 10-year period. this disease was most frequent between the ages of 30 to 40 and mostly in males. low back pain with or without radicular pain was the most frequent symptom, involving the left leg in t...

The nonlocal geometric variational problem derived from the Ohta-Kawasaki diblock copolymer theory is an inhibitory system with self-organizing properties. The free energy, defined on subsets of a prescribed measure in a domain, is a sum of a local perimeter functional and a nonlocal energy given by the Green’s function of Poisson’s equation on the domain with the Neumann boundary condition. Th...

Intervertebral disc (IVD) homeostasis is mediated through a combination of micro-environmental and biomechanical factors, all of which are subject to genetic influences. The aim of this study is to develop and characterize a genetically tractable, ex vivo organ culture model that can be used to further elucidate mechanisms of intervertebral disc disease. Specifically, we demonstrate that IVD di...

BACKGROUND Degenerative discs are thought to produce nerve root pain either mechanically or chemically. Particularly in the case of advanced degenerative disc disease, this clinical entity has often proven to be symptomatically resistant to peridural steroids, Intra-discal Electrothermoplasty (IDET) and direct surgical intervention. Exposure of irritated nerves to hypertonic dextrose is thought...
