[Pseudo-Bartter syndrome in diuretics abuse].

In a 45-year-old woman with chronic hypokalemia, clinical, chemical and endocrinological results pointed to Bartter's syndrome as cause of the disturbance. By screening the patient's urine twice, positive results for furosemide were obtained and we came to the conclusion, that the patient was suffering from Pseudo-Bartter's syndrome due to chronic abuse of diuretics.
