Epileptic seizures provoked by bathing with water at room temperature Volume 14, issue 3, September 2012

A partial seizure with generalisation was provoked in the infant by immersion with lukewarm water during bathing. The seizure onset was characterised by staring, confusion, non-forced right head deviation, and immobility. EEG showed a paroxysmal slowing of the basic rhythm followed by 2-3 Hz high-voltage delta waves, starting above the right fronto-temporal region. The fast unilateral spreading of slow activity and sharp waves was registered with increasing amplitude and decreasing frequency over the whole right hemisphere. After 42 seconds from the seizure onset, the EEG showed diffuse dissemination of high-amplitude (200-300 mcV) rhythm at 2-3 Hz, with clinical correlation of seizure generalisation. After 68 seconds from seizure onset, diazepam was given rectally and the seizure stopped after one minute. During the last 20 seconds of the course of the seizure, oral and hand automatisms were observed while EEG showed rhythmic repetitive sharp waves over the left temporal-parietal region. A) 08.21.24: seizure onset; B) 08.22.05: generalisation; C) 08.22.32: diazepam application; D) 08.23.30: the end of the seizure. EEG conditions: longitudinal montage, calibration: 70 mcV; speed: 10 s/page.
