Marinesco-Sjögren syndrome is rarely reported in the Middle East. This is the 2nd report of Marinesco-Sjögren syndrome in an Arab family. The clinical features of 2 affected brothers are described. Electrophysiological studies of the 2 patients showed primarily myopathic changes, whereas sural nerve biopsy revealed segmental demyelination and axonal(More)
Clinico-radiological assessment of three mentally retarded members of a large Bedouin kindred showed lissencephaly, spastic paraparesis, myoclonic epilepsy and cerebellar hypoplasia. It seems that the familial association of lissencephaly/myoclonic epilepsy/cerebellar hypoplasia represents a new entity.
Forty one patients with the clinical diagnosis of Behçet's syndrome from two teaching hospitals in Kuwait were studied. There were 34 male and seven female patients. Age at presentation ranged from 14 to 48 years. Neurological manifestations were present in 24 patients. Eleven patients showed evidence of increased intracranial pressure, and 10 of these had(More)
The vertex Readiness Potential (RP) (Bereitschaftspotential) preceding self paced voluntary movements is reduced in duration and amplitude in patients with Parkinsonism. It cannot be used as an index for delayed initiation of movement. The negative potential is commonly replaced by a positive slow wave. In hemi-Parkinsonism, the abnormal RP is more apparent(More)
We report a 35-year-old patient with megaloblastic anemia who presented with features of subacute combined degeneration of the cord. Electrophysiological studies showed features of axonal neuropathy. In addition, there was evidence of prominent focal proximal conduction block in several nerves. After treatment with cyanocobalamin the neuropathy improved,(More)
A technique is described of measuring the motor end plate jitter in the orbicularis oculi muscle activated by extra-muscular nerve stimulation, standardised for routine use in diagnosis and evaluation of neuromuscular transmission disorders. Among the advantages of the technique are comparatively quick and easy sampling of adequate number of single motor(More)
Electrical microstimulation of motor axons in conjunction with single fiber EMG (SFEMG) is increasingly used to measure the jitter of the motor endplates. This study examines the jitter of the stimulation site on the axon when stimulus strength is at threshold. In the absence of spurious blocking, this was found to be 5 microseconds on the average. With(More)
Nineteen healthy volunteers (median age, 25; range, 18-51 years) were enrolled in a study to obtain normative values for stimulated jitter in the masseter muscle. Axonal microstimulation was performed via a monopolar needle electrode introduced in the masseter 2-2.5 cm above the mandibular angle on the line connecting it with the lateral canthus. The(More)
Jitter after axonal microstimulation in the masseter muscle was studied in 30 consecutive patients (12 women) with myasthenia gravis (MG). Patients' mean age was 42.3 (12-75), median disease duration was 3 months (1-72), and onset was ocular (15 cases), oculobulbar (7), bulbar (6), or generalized (2). There were 23 newly-diagnosed patients. Nine cases(More)
OBJECTIVE Studies in the literature have demonstrated a gender effect on sensory nerve action potential (SNAP) amplitude for the median and ulnar nerves by use of the antidromic method of recording. The objective of this study was to determine if performing orthodromic sensory nerve stimulation eliminates the gender bias by removing the finger circumference(More)
