Nerves Damaged Spinal Tap
Nerves Damaged During Spinal Tap: Can a spinal tap cause a person pain, numbness and weakness in the right lower leg for life?
The complications resulting from lumbar puncture (spinal tap) have been well documented in the neurosurgical literature. These complications include mild backache, persistent headache, meningitis, and herniated disc, as well as inoculation of epidermal tissue, and the associated growth of epidermoid tumors (Siddiqi and Buchheit, 1982).
There have also been documented cases of nerve root injury associated with spinal tap. Siddiqi and Buchheit have reported a case of an impacted or herniated nerve root associated with lumbar puncture. The patient presented with pain in the lower left leg into the ankle. Their finding of an impacted herniated nerve root, presumably causing postmyelogram sciatica and worsening of the preexisting low-back pain, appears unique. The mechanism of such an injury is thought to be herniation of the nerve root into the spinal needle while the contrast medium or cerebrospinal fluid is being withdrawn after the spinal tap. This suggests that the stylet should be placed before the needle is withdrawn. This phenomenon occurs as the etiology of sciatica and persistent headaches following myelography. In addition to the nerve...
A 66-year-old woman experienced progressive right-sided sciatic pain on gait without any causative episode. She had not had low back pain before this episode. She had hypertension and asymptomatic multiple cerebral infarction, which had been treated by hypotensor and anticoagulant.
On initial examination, she could not walk more than 100 m because of her right sciatic pain, which improved at rest. She showed no limitation on bilateral straight leg raising test. Neither sensory nor motor deficit of her lower extremities was apparent. Vesicorectal functions and reflexes were normal. Plain lumbosacral radiography showed mild lumbar spondylosis. Magnetic resonance imaging (MRI) of the lumbar region disclosed compression of the thecal sac at L4 -- L5 caused by a narrowed spinal canal. Lumbar puncture for myelography was performed without confirmation of the spinal level by an image intensifier. It was difficult to insert a needle (Termo spinal needle, 0.8 mm in diameter and 70 mm in length) into the intrathecal space at the lower…

manifestations of types of traumatic brain injury (focal, diffuse) and hemorrhage (epidural, subdural, subarachnoid)? Focal TBI occurs as a result of some mechanical force acting on the skull (and hence the brain) or penetrating injury to the brain. The manifestations of focal TBI will depend on the particular area of the brain that is damaged (Granacher, 2007). For example, damage to the posterior portion of the left frontal lobe will
Campylobacter jejuni is a helical shaped, non-spore forming, curved, Gram-negative bacteria which is most often found in animal feces. This bacteria comes from the intestinal tracks of animals where is exists as a mixed surface-associated community, protected by an extra cellular material called a biofilm. The protection afforded to the bacteria by the biofilm makes it an extremely resilient bacteria. (Siringan, 2011) It was originally discovered by Theodor Escherich in

Multiple Sclerosis The author of this report has been asked to write up a summary of multiple sclerosis. The subjects that will be talked about will include the definition, the methods of diagnosis, the symptoms of the disorder, the complications of the disorder, the treatments for the disorder, the methods of prevention (if any) and the directions of future research. While multiple sclerosis is not a death sentence by any means,
However, the case studies ignore the discrimination of the incidence of the problem by race or socio economic classification. (Showers, 1992) Generally, the brain and the blood vessels of the babies are considered to be highly vulnerable to the whiplash injuries as a result of their anatomic structures. Besides the head of the baby constitutes about 10% of the weight of the body which is only 2% among the adults.
Neuroscience Hormones and the Nervous System Of the many highly interesting features of the brain and the nervous system that are detailed in this chapter of the text, the one that I found most interesting is the relationship between the nervous system and the endocrine system, which controls the hormones secreted throughout the body. The initial comparison between hormones and neurotransmitters that the text makes initially helps to provide an immediate basic
