Gastroenteritis-related seizures have increasingly gained attention in recent years. Most cases follow a brief, benign course with very few episodes of seizure recurrence and without development of epilepsy. Published reports usually do not make a distinction between febrile and afebrile patients, and most authors include only nonfebrile convulsions in their reported series. This study evaluated the impact of fever in children presenting with seizures during a mild gastroenteritis episode and found that the presence or absence of fever did not affect seizure characteristics or duration. However, mild hyponatremia affected some seizure features, particularly seizure duration, as hyponatremic children sustained more prolonged seizures than patients with normal serum sodium levels, irrespective of body temperature.

Torticollis can be either congenital or acquired. Acquired torticollis is often the manifestation of an underlying central nervous system disorder. Acute painless torticollis should always raise suspicion of a posterior fossa tumor. Acute disseminated encephalomyelitis is an inflammatory demyelinating disease of the central nervous system involving the subcortical white matter, and to a lesser extent, the gray matter. The illness typically has a monophasic course characterized by a variable combination of fever, headache, meningismus, seizures, spasticity, cranial nerve palsies, ataxia, and psychosis. The course, although often clinically severe, is generally benign with most children making a full recovery. A toddler presenting with subacute painless torticollis as the only manifestation of acute disseminated encephalomyelitis is described. The authors believe the neck twist in this child represented a form of dystonia because of basal ganglia involvement. Torticollis has not been reported as a presenting or only sign of disseminated encephalomyelitis.
