Evaluation of therapy of peripheral polyneuritis

Peripheral polyneuritis is not a disease entity but a mystery. The underlying cause should be searched for, but since often it cannot be found, treatment should be started simultaneously with the search. Conservative measures should be tried first-vitamin B complex, niacin, riboflavin, pyridoxine and thiamine chloride; next, injections of liver extract. Then, if no specific condition amenable to treatment has been discovered and if the patient is seriously incapacitated and becoming worse, hospitalization for trial with BAL is indicated.
