Treatment of chronic low back pain exhibiting radicular symptoms poses a clinical problem that has not yet been solved. The technique of percutaneous minimally invasive neurolysis described by Racz is being performed increasingly to treat chronic radiculopathy. A total of 61 patients with corresponding symptomatology after screening for inclusion and exclusion criteria in the region of the lumb...

results at three days, one month, three months, and six months after pea compared to pre-pea evaluations, the pain scores and medication intake were significantly decreased. significant pain relief declined from 95% at three days to 75% at six months. conclusions pea for low back pain due to contained disc herniation is a safe and effective procedure. therefore, it may be considered as an optio...

OBJECTIVES The authors evaluated the effectiveness of percutaneous epidural adhesiolysis (PEA) in patients with low back pain due to contained disc herniation. PATIENTS AND METHODS Twenty patients with low back pain due to contained disc herniation underwent PEA treatment with the Racz technique. The patients were evaluated for pain score, medication intake, significant pain relief, and compl...

BACKGROUND Percutaneous adhesiolysis (PA) is considered to be a reasonable nonoperative treatment for herniation of intervertebral disc (HIVD), spinal stenosis, and post-lumbar-surgery syndrome (PLSS). The success of PA depends on the removal of epidural fibrosis and drug delivery to the target region. However, prognostic predictors of the effects of PA are not well known. OBJECTIVE The aim o...

A 39-year-old woman with no history of trauma or meningitis presented to the neurology department of our hospital with an occipital headache, neck pain, nausea, and dizziness that had worsened during the previous month. The headache worsened when sitting or standing and partially regressed when lying down. She was diagnosed with spontaneous intracranial hypotension (SIH) and received conservati...

This paper examines the performance of Dynamic Neural Tree Networks (DNTNs) which perform hierarchical clustering on unlabelled data. DNTNs are a form of competitive learning neural networks where the competitive neurons are created dynamically, forming a tree configuration which represents the structure inherent in the data set. Two such models have been produced independently by Racz and Klot...
