Lumbar Epidural Varix Mimicking Disc Herniation.

Lumbar radiculopathy is generally caused by such well-recognized entity as lumbar disc herniation in neurosurgical practice; however rare pathologies such as thrombosed epidural varix may mimic them by causing radicular symptoms. In this case report, we present a 26-year-old man with the complaint of back and right leg pain who was operated for right L4-5 disc herniation. The lesion interpreted as an extruded disc herniation preoperatively was found to be a thrombosed epidural varix compressing the nerve root preoperatively.

Evaluation of the effects of mobile phones on the neural tube development of chick embryos.

Aim: The objective of this study is to examine the effects of radiation of mobile phones on developing neural tissue of chick embryos.

Material And Methods: There were 4 study groups. All Groups were placed in equal distance, from the mobile phones.

Simultaneous folate intake may prevent adverse effect of valproic acid on neurulating nervous system.

Purpose: The aim of this study is to elucidate the preventive effect of folic acid (FA) on teratogenic effects of valporic acid (VA) in early stage chick embryos on neural tube development.

Materials And Methods: One hundred and fifty specific pathogen-free (SPF) chick eggs were used to investigate the neurulation in five groups. Group A was the control group.

The results of nucleoplasty in patients with lumbar herniated disc: a prospective clinical study of 52 consecutive patients.

Background Context: Nucleoplasty is a minimally invasive, percutaneous procedure that uses radiofrequency energy to ablate nuclear material and create small channels within the disc.

Purpose: To evaluate the efficacy of nucleoplasty technique in patients with leg pain caused by radicular encroachment.

Study Design/setting: A prospective clinical study of subjects with lumbar disc herniation, and radicular pain resistant to previous medical treatment and physiotherapy for a period of at least 3 months.
