Rapeseeds and Hypertension

PED visit 1: 9-year-old girl, refugee living in an orphanage, presented to the paediatric ED (PED) one day after eating rapeseed pods. She complained of gastrointestinal symptoms (6x non-bilious vomiting, one greenish diarrhoea) and reduced general state without fever.
Vital parameters were within normal limits. On clinical exam the patient appeared very tired but otherwise exam was unremarkable including a soft and non-tender abdomen.
According to Tox Info Suisse gastrointestinal symptoms can occur after ingestion of rapeseeds, though more serious symptoms are not expected.
