even though intervertebral disc degeneration can be found in the natural course of alkaptonuria, detection of the disease by black disc color change in a patient without any other presentation of alkaptonuria is an exceptionally rare condition. we have reported a very rare case of alkaptonuria presented with low back pain and steppage gait in a 51-year-old male with a complaint of chronic low-b...

Coating is one of the innovative approaches used to improve the wear resistance and load-carrying capacity of surfaces in rolling-sliding contact, such as gears and rolling element bearings. In this study, the tribological performance of standard gear material (EN 16MnCr5) and two kinds of powder metallurgy (PM) gear material (Distaloy AQ + 0.2% C and Astaloy 85Mo +0.2% C) with and without trib...

STUDY DESIGN Cross sectional and observational. PURPOSE To evaluate the different aspects of lumbar disc degenerative disc disease and relate them with magnetic resonance image (MRI) findings and symptoms. OVERVIEW OF LITERATURE Lumbar disc degenerative disease has now been proven as the most common cause of low back pain throughout the world. It may present as disc herniation, lumbar spina...

Intervertebral disc degeneration remains a pervasive and intractable disease arising from a combination of aging and stress on the back and spine. The growing field of regenerative medicine brings the promise of stem cells in the treatment of disc disease. Scientists and physicians hope to employ stem cells not only to stop, but also reverse degeneration. However, there are many important outst...

Sagebrush genus (Artemisia scoparia) is the one of the most important genus of Asteraceae family. It has numerous values because of medicine properties. Sagebrush genus has numerous application in traditional medicine from ancient times. In this research, the isolation and identification of essential oil and antibacterial activity of Artemisia scoparia have been studied. Samples were collected ...

In all of 100 consecutive patients referred for retinal angiography with a clinical diagnosis of probable or possible papilloedema a definite diagnosis was made from neurological assessment, neuroradiological investigations, and follow-up. The cases have been divided into 2 groups--those with proved papilloedema and those which have been called either normal or pseudopapilloedema. In all cases ...

INTRODUCTION The lumbar disc represents a complex biological ecosystem dependent on a homeostatic environment. Consistent with a natural ecosystem, demise and degeneration occurs as a consequence of one or a combination of environmental disruptions. With this understanding, we must move away from the general term “degenerative disc disease” (DDD) and move toward the determination of etiology-sp...

Spontaneous intracranial hypotension is frequently idiopathic. The authors report on a patient presenting with symptomatic intracranial hypotension caused by a transdural calcified thoracic disc herniation. Cranial magnetic resonance (MR) imaging revealed classic signs of intracranial hypotension, and a combination of spinal MR and computerized tomography myelography confirmed a mid-thoracic tr...

BACKGROUND Prosthetic replacement of spinal discs is emerging as a treatment option for degenerative disc disease. Posterior dynamic transpedicular stabilization (PDTS) and prosthetic disc nucleus (PDN) devices have been used sporadically in spinal surgery. METHODS This was a prospective study of 13 patients averaging 40.9 years of age with degenerative disc disease who underwent posterior pl...
