RATIONALE: Trans-sacral epiduroscopic laser decompression (SELD) is reported to have strong positive short-term effects in controlling lower back pain (LBP) or radicular leg pain following herniated lumbar disc (HLD). However, little is known about the possible complications following SELD. PATIENT CONCERNS: A 36-year-old man received SELD with YAG laser for controlling LBP and radicular pain due to HLD on L5-S1. However, after SELD, voiding and defecation difficulties and sensory deficits on the S3-5 dermatome were presented...

Introduction. Lyme borreliosis is a multisystem tick-borne disease caused by Borrelia burgdorferi. Neurological manifestations are reported in up to 15 % of adult patients with Lyme disease, while the frequency among children is higher. The most common manifestations are painful radiculopathy, facial nerve paresis and lymphocytic meningitis. Epileptic seizures and cerebral vasculitis with stroke or aneurysms are very rare complications. Case presentation. We describe a paediatric patient with sensorineural auditory dysfunction, headache, fatigue and epileptic seizures as sequelae of meningoencephalitis/Lyme neuroborreliosis (LNB) caused by B...

Leg pain from lumbar disc herniation is a common presentation. However, certain muscular and peripheral nerve variants may present similarly and represent an unrecognized etiology of femoral nerve dysfunction. Such cases might affect the outcome of specific treatment regimes. Therefore, recognition of these variations in anatomy may be useful to the clinician when treating the patient with medically refractory lower limb pain. Some reports have reported variant slips of the psoas and iliacus muscles, which may split the femoral nerve causing a potential risk for nerve entrapment...

Lumbar spinal stenosis (LSS) is a frequent cause of chronic low back and lower extremity pain in older patients. Symptomatic LSS typically is described as neurogenic claudication consisting of pain, weakness, numbness, and/or fatigue arising in the back and radiating into the buttock, thigh, or lower leg. The diagnosis is complicated by lack of reliable clinical or x-ray criteria. North American Spine Society guidelines recommend magnetic resonance imaging study without contrast to confirm anatomic narrowing of the spinal canal or nerve root impingement...

We present a case of double-crushed L5 nerve root symptoms caused by inside and outside of the spinal canal with spur formation of the lumbosacral transitional vertebra (LSTV). A 78-year-old man presented with 7-year history of moderate paresis of his toe and left leg pain when walking. Magnetic resonance imaging (MRI) revealed spinal stenosis at the L3/4 and 4/5 spinal levels and he underwent wide fenestration of both levels. Leg pain disappeared and 6-min walk distance (6MWD) improved after surgery, however, the numbness in his toes increased and 6MWD decreased 9 months after surgery...

Young-Jin Kim
Incidental durotomies are a frequent complication during spinal surgery. Cerebrospinal fluid (CSF) leakage from a dural tear may be visually apparent intraoperatively, but occasionally, a tear may not be recognized during the procedure. We report our experience in 2 cases of postoperative incarceration of nerve root as a cause of sciatica, without CSF leakage intraoperatively. When durotomy attributable to surgical manipulation does occur, intraoperative identification is mandated. If a patient develops unexplainable postoperative pain and neurological deficits after lumbar discectomy, incarceration of nerve root should be considered in the differential diagnosis...

We report the first extraforaminal location of a lumbar discal cyst. The patient was treated by hemilaminectomy, arthrectomy, cyst resection and unilateral arthrodesis, achieving complete release of the nerve root. Extraforaminal lumbar discal cyst may represent an unexpected cause of sciatic pain with favorable outcome after surgical resection.

REVIEW
Aneta S Petkova, Christo B Zhelyazkov, Borislav D Kitov
Spontaneous spondylodiscitis is a rare but serious infectious disease which is a combination of an inflammatory process, involving one or more adjacent vertebral bodies (spondylitis), the intervertebral discs (discitis) and finally - the neighboring neural structures. In most cases the condition is due to a hematogenous infection and can affect all regions of the spinal cord, but it is usually localized in the lumbar area. The most common clinical symptom is a pronounced, constant and increasing nocturnal paravertebral pain, while consequently different degrees of residual neurological symptoms from nerve roots and/or spinal cord may appear...

N-methyl-D-aspartate receptor (NMDAR) activity in the hypothalamic paraventricular nucleus (PVN) is increased and critically involved in heightened sympathetic vasomotor tone in hypertension. Ca(2+)/calmodulin-dependent protein kinase II (CaMKII) binds to and modulates NMDAR activity. In this study, we determined the role of CaMKII in regulating NMDAR activity of PVN presympathetic neurons in male spontaneously hypertensive rats (SHRs). NMDAR-mediated excitatory postsynaptic currents (EPSCs) and puff NMDA-elicited currents were recorded in spinally projecting PVN neurons in SHRs and male Wistar-Kyoto (WKY) rats...
