lumbar disc herniation (ldh) is the most common cause of sciatica and only in about 10% of the affected patients, surgical intervention is necessary. the side of the patient (the side of most prominent clinical complaints) is usually consistent with the side of imaging (the side with most prominent disc herniation on imaging scans). in this case series, we presented our experience in four cases...

background and objectives : resistance among bacterial isolates is the leading cause of increased mortality and morbidity worldwide. carbapenems once thought to be effective are becoming ineffective mostly due to the emergence of carbapenemase. this study was designed to determine in vitro efficacy of modified hodge test for detection of carbapenemase production in gram negative rods. material ...

Disc Degeneration: Spondylosis (Spondylosis Deformans) is a general term used for age-related changes to the disc. This includes disc dessication, bulging and marginal osteophyte. Disc degeneration (Intervertebral osteochondrosis) (Resnick) is characterized by disorganization and dessication of the nucleus pulposis and by disc space narrowing. With loss of disc space height there is annular bul...

INTRODUCTION Varied definitions of disc pathology exist in the literature. Magnetic Resonance Imaging (MRI) classification systems incorporate several qualitative features including disc appearance, the distinction between the nucleus and the annulus, signal intensity and intervertebral disc height. The lack of a continuous measure has made it difficult to sensitively examine degenerative disc ...

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 wa...

antibiotic resistance of intensive care unit (icu) born aerobic gram-negative bacteria was evaluated during a six months period at a teaching hospital in tehran, and determination of the validity of the results obtained from disc diffusion tests, using discs manufactured in iran. disc susceptibility tests using iranian and standard discs (diffusion discs available in international markets) were...
