mydriasis/seizures

Autonomic signs and symptoms are a common feature of epileptic seizures. Although sympathetic activation responses are predominant, we can also find sympathetic inhibition and even an activation of the parasympathetic division of the autonomic nervous system, especially in partial seizures. These

Pupillary dilatation was observed in a young boy who had a sudden onset of right focal seizures. Clinical and laboratory investigation revealed the presence of a benign left frontal epileptic focus. Lacking signs of third cranial nerve compression, this transient pupillary abnormality could be

OBJECTIVE To describe the clinical features of syncope-like epileptic seizures (SLES) and their frequency in Panayiotopoulos syndrome (PS). METHODS This was a 6-year prospective study of all children aged 1-15 years referred for an EEG. PS was defined by the occurrence of at least one autonomic

BACKGROUND A complex partial seizure can cause a variety of visual system signs and symptoms, including visual hallucinations, dilated pupils, and changes in vision. Little information is known about the influence of this disorder on the visual system during nonseizure moments. This case report

Electrographic and clinical observations were made as long as 2 months after the injection of ibotenic acid (IBO) solution (50 micrograms in 1 microliter of phosphate buffer solution) through a chronically implanted cannula into unilateral amygdala of freely moving and non-anesthetized cats. The

A 41-year-old woman presented unconscious with fixed dilated pupils following a massive overdose of carbamazepine and an unknown quantity of venlafaxine prescribed for the management of bipolar affective disorder. Her course in the intensive care unit was marked by a number of complications related

BACKGROUND Although arteriovenous malformations (AVM)-related intracranial hemorrhage (ICH) is infrequently devastating, there is a subgroup of patients that present comatose requiring immediate surgical treatment. We sought to determine the outcome and prognostic factors in those patients with

Lidocaine (a sodium channel blocker) serves as an antiepilepsy drug in neonates. We present a neonate with a seizure disorder who acutely developed pupillary mydriasis secondary to lidocaine overdose. We suggest adding this side effect to the list of untoward effects of lidocaine and to the

Introduction: Acute ischemic stroke (AIS) is a rare event in infancy. Besides vasculopathy, thrombophilia, or cardiac disorders, cancer and chemotherapy are known predisposing factors for AIS. Leukemia can be associated with different abnormal coagulation parameters, but severe bleeding or

A subject who apparently swallowed a baggie containing "crank" (methamphetamine) while being arrested, was admitted to hospital and then experienced a massive overdose of the drug. The subject went through a seizure with associated fixed dilated pupils, and a depressed pulse and blood pressure. His

A 21-year-old man sustained a closed fracture of the leg from an industrial accident, without associated head trauma. The orthopaedic treatment consisted of immediate immobilization by setting leg in plaster. Two hours after admission, the Glasgow coma scale score was 10. Four hours after admission

The subarachnoid bolt has been used extensively to monitor intracranial pressure in a variety of conditions. We have had two patients who had subarachnoid bolts in place that were thought to be functional in whom evidence of increased pressure was present. In one case, the patient had Reye's
