Water hemlock is a ubiquitous plant that can be mistaken for a turnip as in the case reported. Oral ingestion causes an explosive illness consisting of nausea, vomiting, abdominal cramps, and grand mal seizures that can progress to cyanosis and death. In the reported case a 30-year old man was found semi-comatose some 75 minutes after ingesting a "turnip". The history revealed profuse emesis shortly after eating lunch that changed from bile to frank blood. There was a mean orthostatic blood pressure change of 30 torr, with an increase in the heart rate of 10%. Neurologic examination revealed a lethargic patient. Following administration of 4 liters of Ringer's lactate the patient's blood pressure stabilized and with continued isotonic fluid maintenance he improved rapidly. This case indicates that appropriate management should be directed toward protecting the patient's airway from gastric aspiration, restoring the intravascular and extracellular volume deficit, and controlling cerebral edema.

A 42-year-old man with refractory epilepsy experienced a 1-min generalized tonic-clonic seizure followed by persistent inspiratory stridor and cyanosis while being monitored in our epilepsy monitoring unit (EMU). Although his cardiac parameters remained stable throughout the event, the patient's respiratory status rapidly declined, despite the urgent administration of oxygen via bag-valve-mask. He was subsequently intubated by the emergency code team, who noted severe laryngospasm while trying to insert the endotracheal tube. The patient was successfully resuscitated. This monitored case demonstrates that postictal laryngospasm may represent another potential cause of sudden unexpected death in epilepsy (SUDEP).

Sudden unexpected death in epilepsy (SUDEP) is the most important direct seizure-related cause of death, and most cases usually occur in patients with intractable, longstanding epilepsy. Suspected mechanisms for SUDEP include central and obstructive apnea, cardiac arrhythmia, postictal respiratory arrest, and primary cessation of brain activity. We report a patient who experienced a near SUDEP following his first prolonged tonic-clonic seizure requiring intubation. Chest X-ray examination showed severe bilateral congestion of the middle and superior pulmonary fields and an enlarged heart. Observations of pulmonary compromise in near-miss patients are extremely rare. Our patient showed marked cyanosis and respiratory distress after the index seizure, in agreement with the view that respiratory distress was the primary etiology in this case. Moreover, this observation confirms that SUDEP is not exclusively an issue for patients with chronic, uncontrolled epilepsy.

A 40-year-old man presented to the emergency department with dyspnoea and fatigue after bupropion and popper consumption. Clinical examination was remarkable for central cyanosis not responding to supplementary oxygen. Arterial blood gas analysis showed a methaemoglobin value of 30.3%. Methaemoglobinemia was diagnosed and the patient was treated with methylene blue. However, during methylene blue administration, the patient developed a generalized tonic-clonic seizure that was successfully managed with diazepam. Combined intoxications can be a critical problem in the emergency department. Early recognition and treatment of poisoning are key for good patient outcome.
