MRI evidence of mesial temporal sclerosis in subjects without seizures.

The identification of mesial temporal sclerosis (MTS) on magnetic resonance imaging (MRI) is critical in the evaluation for temporal lobectomy. The purpose of this study was to estimate the prevalence of MTS by MRI in the general population. We reviewed the charts of patients undergoing MRI scans over an 18-month period. In order to be included, patients had to have no history of seizures, and the MRIs had to read as 'normal'. Patients were excluded if there was a history of seizures, mental illness, or alcohol abuse, and if they had a family history of seizures. Ages had to be from 5 to 50 years. All patients had MRI scans performed in three planes on 1.5 T systems. MRI diagnosis of MTS was based on standard visual diagnostic criteria analyzing: (1) hippocampal atrophy and (2) increased hippocampal T2 signal. Out of 375 charts reviewed, 204 met the inclusion criteria. Of the 204, 29 (14%) had abnormal and asymmetric mesial temporal structures consistent with a diagnosis of unilateral MTS. Nineteen (9.3%) had hippocampal atrophy only, two (1%) had T2 signal abnormalities, and eight (4%) met both criteria. There are some 'false positives' and MRI evidence for MTS is only meaningful in the proper clinical context.

Does the neurologist contribute to the care of patients with chronic back pain?

OBJECTIVE: To review the disposition and outcome of patients with back pain seen in a neurology clinic, and determine the value of the neurologist's input. BACKGROUND: Back pain is a common cause of referral to the neurology clinic, but it is not clear how much the neurologist contributes to the care of such patients. DESIGN/METHODS: We reviewed all new patients and new consultations seen for the following reasons: low back pain; 'sciatica'; 'back and leg pain', and 'spinal stenosis'. Patients were evaluated by a single attending neurologist at a general neurology clinic over a 2-year period (January 1997 through December 1998). RESULTS: During the 2-year period, there were 97 patients seen for the above reasons. The chief complaint was low back pain alone in 73, while it was combined with another symptom in 24 (leg pain in 18, buttock or hip pain in 6). Thirty-three patients were self-referred, 56 were referred by a healthcare professional, 3 were referred by attorneys, and the referral source was unclear in 5. Median age was (range 25-90) years. Forty-eight were males. Based on the clinical data (history and examination), clinical diagnoses were radiculopathy in 28, myelopathy in 2, uncomplicated spondylosis in 27, and other non-neurologic conditions in 45. Tests performed after the visit included X-rays in 31, CT in 1, MRI in 16, and EMG in 17. 'Final' diagnoses were radiculopathy in 29 patients, myelopathy in 2 (total neurologic n = 30), uncomplicated spondylosis in 27, and other non-neurologic diagnoses in 41 (total non-neurologic n = 67). The non-neurologic diagnoses included periarticular pain, bursitis, muscle strain, soft tissue injury, and vertebral compression fractures. Final dispositions in the non-neurologic group (n = 67) were: nonsteroidal anti-inflammatories (NSAIDs) in 34 patients; analgesics or muscle relaxants in 37; physical therapy for 19, and none (including rest and observation) for 22. Four patients were referred for epidural blocks. (Many patients had more than one final disposition.) Final dispositions in the neurologic group (n = 39) were: physical therapy (n = 9); NSAIDs (n = 12); analgesics or muscle relaxants (n = 12), and epidural blocks (n = 3). Three patients were referred for surgery, but only 1 had an operation. CONCLUSIONS: Of patients with back pain and related symptoms seen in a neurology clinic, about two thirds have non-neurologic conditions. These patients are usually treated symptomatically with medications, rest, and physical therapy, all of which could be managed by primary care physicians. In the neurologic group, the vast majority is treated in the same way as the non-neurologic group. When more specific measures are needed, such as surgery or pain management procedures (e.g., epidural blocks), then the patients could be evaluated directly by the proper specialist (pain management or spine surgery) rather than the neurologist. The neurologist's input does not significantly affect the diagnosis or the management, so that the neurologist appears to have no useful role in the management of such patients.
