Tumor-like presentation of multiple sclerosis.

Multiple sclerosis patients may present with clinical data suggestive of cerebral tumor, however, most of the lesions do not show expansive signs in computerized tomography of brain or magnetic resonance imaging. We report in this paper, 2 patients who had shown expansive radiological signs suggestive of neoplasm. Cerebral biopsy was an important diagnostic procedure in these 2 cases which revealed the diagnosis of demyelinating disease.

Parkinson's disease. Clinical and electrophysiological evaluation.

Objectives: Identification of the clinical spectrum and the electrophysiological responses of a Saudi population with Parkinson's disease as opposed to a matched normal population.

Methods: Fifty four subjects (41 males and 13 females) were selected for the study. The patients were clinically evaluated for the occurrence of Parkinson's disease symptoms, as well as other associated medical conditions.

Random total antiepileptic drug levels and seizure control during pregnancy.

Objective: To study the correlation of randomly-tested total antiepileptic plasma levels and seizure control in a retrospectively collected group of pregnant epileptic Saudi women.

Methods: The medical records of 30 Saudi epileptic female patients were reviewed during their subsequent pregnancies (total of 50). The type of antiepileptic drugs used during each pregnancy, the dose of each drug and the corresponding total plasma levels were noted.

Motor terminal latency index in carpal tunnel syndrome.

We determined the motor terminal latency index (MTLI) of the median nerve across the carpal tunnel in 41 upper extremities of 31 patients with carpal tunnel syndrome. Changes in motor nerve conduction velocity (MNCV), motor terminal latency (MTL), sensory action potential and the amplitude of the compound muscle action potential recorded from the abductor pollicis brevis muscle were all suggestive of proximal and distal segment involvement of the nerve across the carpal tunnel. There was no correlation between forearm MNCV and MTL (r = 0.
