Two novel bacterial strains, designated DOKDO 025(T) and DOKDO 023(T), were isolated on Dokdo Island, Korea, from the rhizosphere of the brown alga Ecklonia kurome. The strains were subjected to a polyphasic taxonomy study and were found to be Gram-negative, aerobic, rod-shaped, non-motile and orange-coloured. The isolates shared 96.3 % 16S rRNA gene(More)
OBJECTIVE Lumbar transforaminal epidural steroid injections are procedures often utilized in the treatment of low back pain associated with radicular pain. Particulate steroids have been known to play a role in embolism. It is, unknown whether nonparticulate steroids are as effective as particulate steroids. To investigate the effect of an epidural steroid(More)
BACKGROUND Chronic low back pain can be a manifestation of lumbar degenerative disease, herniation of intervertebral discs, arthritis, or lumbar stenosis. When nerve roots are compromised, low back pain, with or without lower extremity involvement, may occur. Local inflammatory processes play an important role in patients with acute lumbosciatic pain. The(More)
BACKGROUND Lumbar transforaminal epidural steroid injections (TFESIs) are procedures often utilized in the treatment of radicular pain. TFESIs with a preganglionic approach have been reported to be more effective than TFESIs performed using a classic approach. However, it is unknown whether TFESIs using a retrodiscal approach are as effective as other(More)
OBJECTIVE Peripheral nerve injury often leads to neuropathic pain, which is characterized by burning pain, allodynia, and hyperalgesia. The role of the sympathetic nervous system in neuropathic pain is a complex and controversial issue. It is generally accepted that the alpha adrenoreceptor (AR) in sympathetic nerve system plays a significant role in the(More)
Aspiration biopsy is a rapid and relatively painless technique for evaluating an abnormal prostate gland. It can be performed on outpatients without anesthesia and is easily tolerated. It sensitivity in detecting cancer is at least equivalent to that of core biopsies, in part because several areas of the prostate may be sampled in a relatively atraumatic(More)
BACKGROUND Spinal stenosis is a narrowing of the spinal canal, which causes mechanical compression of spinal nerve roots. The compression of these nerve roots can cause low back pain and/or leg pain, as well as neurogenic claudication. Lumbar epidural steroid injections have commonly been used in patients with lumbar spinal stenosis (LSS). In cases that are(More)
We present a case report in which spinal cord stimulator trial lead became lodged in the posterior lumbar soft tissue. The lead could not be removed even with moderate force or with spine in the flexed position. Radiologic evaluation revealed that edge of metallic lead was wedged into the soft tissue. We were able to remove the lead only after placing the(More)
BACKGROUND The objective was to evaluate the distance from the skin and the diameter of the piriformis muscle and their relationship to the body mass index (BMI). METHODS The study was a prospective study involving 60 patients. Patients were prepared on a radiological table in the prone position. Several images were obtained of each. In this view, the(More)
