[A Lot of Hot Steam: the Cannabinoid Hyperemesis Syndrome]

The 43-year-old patient was admitted because of vomiting and abdominal pain. He had a history of depression and multiple discus prolapses. He reported the consumption of three beers per day.

The patient presented diffuse abdominal pain. The serume-kreatine was elevated (205 µmol/l), there was a leucocytosis (18,4^3/µl) and a mild elvation of y-GT (2,3µkat/l). Stool culture was negative. An abdominal ultrasound and a gastroscopy did not show groundbreaking findings.

The acute kidney injury was treated by administration of intravenous fluid. The vomiting persisted despite of administration of Metoclopramid and Dimenhydrinat. Just Lorazepam and hot showers brought relief of symptoms. A decided drug history revealed a marijuana abusus. After ceasing marijuana consumption and administration of Haloperidol the vomiting stopped.

The cannabinoid hyperemesis syndrome is characterized by vomiting, diffuse abdominal pain and taking hot showers. With typical combination of symptoms a drug history should be taken. The knowledge of this syndrome can help to avoid overdiagnostic.
