Uveitis and central nervous system vasculitis.

Vasculitis confined to the central nervous system (CNS) is a rare disease usually characterized by headache and focal neurologic symptoms. Patients with primary vasculitis of the CNS may have symptoms and laboratory findings of systemic disease such as fatigue and elevated erythrocyte sedimentation rate, but by definition, focal inflammation should not be present outside the CNS. We describe 3 patients with uveitis in association with this diagnosis. The recognition of this association adds to the complex differential diagnosis of uveitis in association with CNS disease, and indicates that "isolated" angiitis of the CNS may display clinical features outside the brain and spinal cord.

Endogenous antibody production to botulinum toxin in an adult with intestinal colonization botulism and underlying Crohn's disease.

A patient with obstruction of the terminal ileum from Crohn's disease developed complete paralysis in week 1 of hospitalization. Features initially suggested Guillain-Barre syndrome, but botulinum toxin was identified in serum and stool specimens from week 1 and type A toxin-producing Clostridium botulinum in stool specimens from weeks 3 to 19, confirming botulism due to intestinal colonization. In week 19, the inflamed small bowel was resected, and C. botulinum disappeared from the stool. In week 31, the patient was able to breath without assistance. Testing for an active immune response with neutralizing antibodies to C. botulinum at week 19 was positive; these antibodies remained at a protective level for >1 year. Intestinal colonization botulism, rare in adults, should be considered for patients with descending paralysis, especially those with a preceding alteration in small bowel function. An active immune response to botulinum toxin with production of protective antibodies has not been demonstrated previously in a patient with botulism and may have contributed to this patient's recovery.

American Association of Electrodiagnostic Medicine guidelines for outcome studies in electrodiagnostic medicine.

Based on a review of the literature and the clinical research experience of the authors and reviewers, the AAEM proposes 17 criteria which should be used to construct and evaluate diagnostic and/or therapeutic outcome studies for patients with symptoms and signs of neuromuscular diseases. Neuromuscular diseases are defined as diseases that cause pathology and/or dysfunction of the sensory, motor, and/or autonomic nerve offers and/or muscles.

Peripheral nerve and neuromuscular disorders.

Mononeuropathies, plexopathies, and radiculopathies may occur with increased incidence during pregnancy and the puerperium. Immunologically mediated disorders of peripheral nerve, neuromuscular junction, and muscle have distinctive management problems when they occur during pregnancy.

The role of imaging in the diagnosis of carpal tunnel syndrome.

Potentially, imaging of the carpal tunnel may expand our understanding of the pathogenesis of CTS. Future studies should correlate imaging results with the patients' clinical status and results of electrodiagnostic tests. Canal pressure studies are not clinically routine, but a research study correlating canal pressure with canal appearance might be of interest. The diagnostic accuracy of imaging studies needs further clinical validation. Currently, it is premature to promote or advertise carpal tunnel imaging as a diagnostic modality for CTS.

Neuromuscular blockade with anti-axoplasmic antibodies.

In the process of developing an immunopharmacologic method for identifying a "trophic" protein released from motor nerve terminals, a soluble fraction of peripheral nerve axoplasm was prepared. An attempt was made to eliminate contaminating myelin and basic protein. Antibodies were produced to soluble nerve proteins in all sheep immunized. On boosting, after a 6-week interval, the animals became weak, and some could not stand on the fifth day after injection. A distinct component of neuromuscular blockade was demonstrated electrically and in response to edrophonium. Because this syndrome was (1) in the broadest sense, an experimental allergic neuropathy but produced by a distinctly different antigen than has been utilized previously (the soluble nerve proteins represented the axoplasmic compartment) and (2) a clinical condition associated with a defect in neuromuscular transmission, this may represent a new and potentially important model in the study of neuromuscular and other neurologic diseases.
