All that glitters is not gold: A spinal epidural empyema following epidural steroid injection

2020

Background: Therapeutic epidural spinal injections (ESIs) of steroids are one of the most common nonsurgical management modalities employed for alleviating pain due to chronic persistent lumbar spinal disease. However, it is well documented that they have significant risks and complications without any long-term efficacy. ESI may result in epidural empyema which may be difficult to diagnose with delays resulting in significant permanent neurological sequelae. Case Description: A 45-year-old female presented with a lumbar spinal epidural empyema after receiving ESI for low back and right leg pain due to a lumbar disc herniation. Laboratory studies showed elevations of multiple inflammatory …

Microsurgical fenestration of perineural cysts to the thecal sac at the level of the distal dural sleeve

2011

Background Surgery for symptomatic sacral perineural cysts remains an issue of discussion. Assuming micro-communications between the cyst and thecal sac resulting in a valve mechanism and trapping of CSF as a pathomechanism, microsurgical fenestration from the cyst to the thecal sac was performed to achieve free CSF communication. Methods In 13 consecutive patients (10 female, 3 male), MRI revealed sacral perineural cysts and excluded other pathologies. Micro-communication between the thecal sac and the cysts was shown by delayed contrast filling of the cysts on postmyelographic CT. Surgical fenestration achieved free CSF communication between the thecal sac and cysts in all patients. The p…

Somatosensory evoked potentials after posterior tibial nerve stimulation — normative data in children

2000

We report normative data of somatosensory evoked potentials to posterior tibial nerve stimulation from 47 children 4–15 years of age. We recorded near-field potentials from the peripheral nerve, the cauda equina, the lumbar spinal cord and the somatosensory cortex. Far-field potentials were recorded from the scalp electrodes with a reference at Erb's point and on the earlobe. The near-field potentials N8 (peripheral nerve) and P40 (cortex) were present in all children. N20 (near-field from the cauda equina) was recorded in 38 subjects. N22 (near-field from the lumbar spinal cord), P30 and N37 ( both farfield waveforms probably generated in the brainstem) were recorded in 46 subjects each. T…

Herniation of an intervertebral disc with cauda compression syndrome in childhood.

1979

A case of a lumbosacral disc herniation of traumatic origin with compression of the cauda equina in a child is reported. The problems of early diagnosis, timely operative procedure, and prognosis of neurological deficit of operated disc herniation in childhood are discussed.

Catheters in Regional Anesthesia

2014

Anesthesiologists use different types of catheters in the performance of continuous regional anesthetic techniques such as epidural, subarachnoid, and paravertebral blocks, as well as peripheral nerve blocks.

3D interactive model of lumbar spinal structures of anesthetic interest

2014

A 3D model of lumbar structures of anesthetic interest was reconstructed from human magnetic resonance (MR) images and embedded in a Portable Document Format (PDF) file, which can be opened by freely available software and used offline. The MR images were analyzed using a specific 3D software platform for biomedical data. Models generated from manually delimited volumes of interest and selected MR images were exported to Virtual Reality Modeling Language format and were presented in a PDF document containing JavaScript-based functions. The 3D file and the corresponding instructions and license files can be downloaded freely at http://diposit.ub.edu/dspace/handle/2445/44844?locale=en. The 3D…

Neurogenic bladder and disc disease: a brief review.

2013

Neurogenic bladder refers to morphofunctional alterations of the bladder-sphincter complex secondary to central or peripheral neurological lesions. Discal etiology can be suggested by clinical observation in patients complaining of classical lower back pain, but not excluded even without musculoskeletal pain. This review provides a brief overview of associations between neurogenic bladder and disc disease, analyzing neuroanatomy, pathophysiology, clinical and urodynamic findings. Therapy is reviewed focusing on etiological treatments.The literature search was performed on PubMed, Medline and Google scholar using the following keywords: 'neurogenic bladder', 'disc herniation', 'disc prolapse…

Pseudopathological vertebral changes in a young individual from Herculaneum (79 C.E.)

2019

Post mortem abnormal modification of bone are known as pseudopathologies. The geochemical characteristic of the burial soil and/or the presence of biological agents may produce marked changes in bone preservation. This could be the case for a young individual, E74, from Herculaneum, which was a Roman town near Naples completely destroyed by the volcanic eruption of Mt. Vesuvius in 79 CE. E74 is an incomplete skeleton of a male individual of 7-8 years of age. Its second and third cervical vertebrae, the eighth thoracic vertebra and the first lumbar vertebra show a septum dividing the vertebral foramen. This condition could be diagnosed as diastematomyelia that consists of the splitting of th…
