ABSTRACT
The case history of a patient with polyradiculoneuritis with symmetrical ascending motor weakness and distal sensory impairment (Guillain-Barré syndrome) is reviewed in relation to a new application of electromyographic biofeedback. In addition to the normal therapeutic procedures, a special device was used to control the amount of therapeutic exercise delivered to the patient in one muscle grouping. Results indicate that this type of adjunctive therapy adds to the current methods of evaluation and treatment of maintaining a patient's interest over a lengthy hospitalization, allowing the therapist to attend several patients simultaneously, and enabling continuous quantitative evaluation of the patient's progress.

The prostaglandins are synthesized in a variety of tissues and participate in an extensive number of physiologic processes. As prostaglandin concentrations have not been reported in infants and children, we measured PGE levels from birth through childhood. PGE levels in cord blood were significantly higher than those in adults. By 48 to 72 hours of age, however, they had fallen to levels that were significantly lower than those in adults. Although PGE concentrations increased with age, they remained significantly lower than did adult levels. These low levels may be related to some of the functional pecularities of the immature kidney.

In order to gain insight into factors controlling aldosterone secretion during the first year of life, we studied the relationships between PRA, serum potassium, sodium, and serum aldosterone levels. While we found a dissociation during the early neonatal period, there was a high degree of correlation between serum aldosteron, PRA, and serum potassium by 3 to 12 months of age. This suggests that aldosterone secretion in the 3- to 12-month-old child, as in adults, is regulated by the circulating levels of potassium and angiotensin II.
