||The first study
in which the disease was associated to oil ingestion was performed in a pediatric hospital
in Madrid. After checking that antibiotic administration to children did not improve their
health status and they presented symptoms like those produced by an intoxication, a
correct hypothesis was established in order to develop a study in which they observed the
first evidence of a relationship between a specific type of oil and the disease.
