Motor unit territories in juvenile myoclonic epilepsy patients.

In this study, the scanning EMG technique was implemented to investigate electrophysiological cross-sections of the motor unit (MU) territories in healthy volunteers and in subjects with juvenile myoclonic epilepsy and spinal muscular atrophy. Measurements were taken intramuscularly by means of two concentric needle electrodes from biceps brachialis muscles. 3-D maps of the MU territories were plotted for each MU to determine the lengths of MU cross-section and the maximum amplitudes of each MU. There was evidence of a preponderance of large MUs in patients with juvenile myoclonic epilepsy.

Relapsing significant bacteriuria: effect on urinary tract infection in patients with spinal cord injury.

OBJECTIVE: To evaluate whether there is a relation between relapsing significant asymptomatic bacteriuria (ASB) and symptomatic urinary tract infection (UTI), and to determine the frequency rate of UTI in patients with spinal cord injury (SCI) using indwelling catheters (IC). DESIGN: Cohort study. Patients were followed up for 24 to 270 days (mean, 66.3 +/- 42.2). SETTING: A department of physical therapy and rehabilitation in a research hospital of a university referral center. PATIENTS: Fifty patients with SCI using IC. Patients with severe concurrent illness, known vesicouretheral reflux, urinary calculi, and severely disturbed renal function were excluded. MAIN OUTCOME MEASURE: Symptomatic UTI, relapsing ASB, and recurrent significant ASB. RESULTS: There was significant difference between relapsing ASB and recurrent ASB with regard to occurring symptomatic UTI (chi 2, 4.92; p < .03). Symptomatic UTI was observed at a rate of 9.35, relapsing ASB 35.59, and recurrent ASB 55.80 per 1,000 patient-days. CONCLUSION: Relapsing ASB is an important factor in the development of symptomatic UTI.
