Left cardiac myxoma and consecutive embolization into the brain is well documented, whereas the association of myxoma with multiple fusiform cerebral aneurysms is rare. A 48-year old female with chronic renal failure had complained of syncope after receiving hemodialysis. An echocardiogram showed a 3 x 4 cm sized myxoma and brain MRI displayed multiple fusiform aneurysms. The myxoma was successfully removed. Postoperatively, she developed status epilepticus. Unfortunately, the patient did not recover and expired due to sepsis.

The incidences of seizures and epilepsy in the population show a peak after 60 years of age. Due to the lack of reported clinical aspects of seizure and epilepsy in the older patients in our region in Iran, this study was conducted to describe the clinical manifestation, etiology, differential diagnosis, and epilepsy subtypes of epilepsy and seizure. A cross-sectional retrospective study was performed on all consecutively elderly seizure and epilepsy patients, referred to the Epilepsy Association in the city of Qom, Iran over a 10-year period. A total of 466 patients aged >60 years were admitted. 31 % of the patients had epilepsy or seizure and 69 % of them had non-epileptic events. The most prevalent differential diagnoses in the beginning were syncope and cardiovascular disorders. The most frequent clinical symptom of epilepsy was generalized tonic-clonic seizures (75 %). The most common cause of seizure was systemic metabolic disorder (27 %). In epileptic elderly patients, no cause was ascertained for 38 % and the most frequently observed pathological factors were cerebrovascular diseases, which accounted for 24 %. The most common type of epileptic seizure was generalized epileptic seizures (75 %). 10 % of elderly epileptic patients suffered from status epilepticus, which was primarily caused by anoxia. Despite the rising rate and potentially profound physical and psychosocial effects of seizures and epilepsy, these disorders have received surprisingly little research focus and attention in Iran. Referring older patients to a specialist or a specialist epilepsy center allows speedy assessment, appropriate investigation and treatment, and less likely to miss the diagnosis.

Breath holding spells are a common and dramatic form of syncope and anoxic seizure in infancy. They are usually triggered by an emotional stimuli or minor trauma. Based on the color change, they are classified into 3 types, cyanotic, pallid, and mixed. Pallid breath holding spells result from exaggerated, vagally-mediated cardiac inhibition, whereas the more common, cyanotic breathholding spells are of more complex pathogenesis which is not completely understood. A detailed and accurate history is the mainstay of diagnosis. An EKG should be strongly considered to rule out long QT syndrome. Spontaneous resolution of breath-holding spells is usually seen, without any adverse developmental and intellectual sequelae. Rare cases of status epilepticus, prolonged asystole, and sudden death have been reported. Reassurance and education is the mainstay of therapy. Occasionally, pharmacologic intervention with iron, piracetam; atropine may be of benefit. Here we present 2 cases, one of each, pallid and cyanotic breath holding spells.

Electroencephalogram (EEG) recording in the laboratory lasts at least 20 minutes and uses 19 active electrodes. It includes rest periods, stimulation procedures, a 3-mn hyperventilation period and intermittent photic stimulation (IPS). Recorded at the bedside, the EEG uses at least eight electrodes; the stimulation procedures, duration of the EEG and need to repeat the examination depend on the indication. Simultaneous video recording is recommended. The EEG report describes the basic rhythm, its reactivity and pathological activities, whether epileptic or not, and their organization. The synthetic conclusion interprets the results while taking into account the clinical context and contributes, if possible, diagnostic and/or therapeutic help in patient management. EEG performed as soon as possible after a seizure is essential for the diagnosis and initial management of epilepsy. It is helpful to characterize the epileptic syndrome in order to initiate optimal treatment. EEG is also useful in managing the withdrawal of antiepileptic drugs. EEG is also extremely useful in case of impaired consciousness, confusional state or even acute or subacute cognitive disorders. It is the only available tool able to validate the diagnosis of non-convulsive status epilepticus presenting with confusional state. EEG helps in the diagnosis of toxic or metabolic encephalopathy and can assess its severity, especially in hepatic encephalopathy. Except in rare exceptions, EEG is not routinely indicated for the evaluation of typical vasovagal syncope, headaches, dizziness, typical transient global amnesia and transient ischemic attack. EEG is irreplaceable in the diagnosis and management of certain severe and frequent pathologies involving the cerebral cortex.

Neurologic complications have long been associated with influenza. A novel strain of influenza A (H1N1) first described in humans to have outbreak potential in 2009 in Mexico went on to become the first influenza pandemic of this century. We evaluated the neurologic complications of the novel influenza A (H1N1) 2009 in children and adults admitted to all public hospitals in Singapore during the influenza A (H1N1) 2009 pandemic between May 2009 and March 2010. All patients were positive for novel H1N1 infection and presented with neurologic symptoms prior to oseltamivir treatment. Ninety-eight patients (median age 6.6 years, range 0.4-62.6) were identified; 90 % were younger than 18 years; 32 % suffered from preexisting neurological, respiratory, or cardiac disease; and 66 % presented with seizures. Of those presenting with seizures, new onset seizures were the most common manifestation (n = 40, 61.5 %), followed by breakthrough seizures (n = 18, 27.7 %) and status epilepticus (n = 7, 10.8 %). Influenza-associated encephalopathy occurred in 20 %. The majority of children (n = 88) presented with seizures (n = 63, 71.6 %), encephalopathy (n = 19, 21.6 %), and syncope (n = 4, 4.5 %). Among adults, a wider range of neurological conditions were seen, with half of them presenting with an exacerbation of their underlying neurological disease. The neurological symptoms developed at a median of 2 days after the onset of systemic symptoms. The median length of hospital stay was 3 days, and 79 % were monitored in general wards. Neurologic complications associated with the novel influenza A (H1N1) 2009 strain were generally mild and had a good outcome. They occurred more frequently in patients with underlying neurological disorders. Seizures and encephalopathy were the most common manifestations, similar to other influenza virus strains.

Carbon monoxide (CO) poisoning is one of the most serious medical emergencies causing life-threatening conditions, including cardiovascular and neurological sequelae. Acute CO poisoning can lead to myocardial ischemia, ventricular arrhythmia, syncope, seizures, and coma. Seizures and other neurological complications in the early stages of presentation are related to severe intoxication in CO poisoning. In such situations, aggressive hyperbaric oxygen therapy is recommended. In CO poisoning, non-convulsive status epilepticus has rarely been observed following hyperbaric oxygen therapy (HBO2). We report a case of CO poisoning presenting as non-convulsive status epilepticus treated with HBO2. Mechanisms and implications for non-convulsive status epilepticus provocation during HBO2 treatment are discussed.
