Ulnar nerve involvement is the second most common local mononeuropathy. The ulnar nerve consists of motor and sensory fibers that arise in C8-T1 roots and extends to the lower trunk and medial cord of brachial plexus. Manifestations of this nerve involvement range from elbow pain and intermittent hand paresthesia to marked sensory loss, wasting and weakness  of hand muscles and a claw hand. Ulnar nerve lesion in the elbow region commonly follows surgery in which general anesthesia is used (particularly in patients with coronary artery bypass graft surgery). The patient presented in this article was a 56-year-old male who was involved in left ulnar nerve lesion after undergoing coronary artery bypass graft. In electrodiagnostic study we noticed diffused demyelination lesion of the ulnar nerve with dominancy in elbow region along with secondary axonal degeneration. Therefore, suitable positioning of elbow is recommended to avoid the  nervous complications of these operations.

 Background & Objectives: Acute optic neuritis in majority of cases, especially young females, is a common presentation of multiple sclerosis. Visual evoked potential (VEP) study is a non-invasive method for evaluation of nerve conduction of optic nerve. This study is an attempt of follow patients with acute optic neuritis and VEP variations over the time.

 Methods: VEP was studied in 30 patients with acute optic neuritis (25 females (83.3%) and 5 males (16.7%) with a mean age of 28.77±9). Clinical examinations and brain MRI study were performed on each. Examinations were repeated 1 and 6 months later. Statistical analyses were performed with SPSS software(rel.11).

 Results: Physical examination revealed another neurologic abnormality in 12 patients (40%). Brain MRI in 19 patients (63.3%) was abnormal. Latency of P100 was abnormal in all cases and only in 7 cases VEP was in normal range after 6 months. Definite MS was diagnosed in 15 cases (50%) and probable MS in 4 patients (13%). P100 amplitude in first study had no prognostic value for recovery.

 Conclusion: VEP has a sensitivity of about 80% for optic nerve injury and the comparison between two eyes is required for the diagnosis of this disorder. Careful clinical examination and brain MRI in the first admission as well as follow-up activities should be done for early detection of multiple sclerosis.
