Case report of a 35 years old patient, who, without previous history of epilepsy, within two years experienced two long-lasting psychotic episodes due to non-convulsive status epilepticus with complex partial seizures. During the second psychotic episode she developed ictal vegetative phenomena such as profuse sweating, flush, apnoea, and, above all and most alarming, periods of severe bradycardia and asystolia with clinical signs of syncope. Ictal asystolia, though being an uncommon sing of epileptic seizures, may be one cause of sudden unexpected death in epileptics.

A recently proposed diagnostic class, psychotic trigger reaction, is deduced from careful clinical studies of eight white men, who upon a very specific trigger stimulus committed murder or attempted to (and in one case also rape). The new class is defined as a sudden ego-alien, motiveless (at least with respect to aggression), motor-wise well organized, violent complex action without emotional concomitants. The action is evoked (not provoked) by an individually unique stimulus within a specific context reviving repeated past traumatic experience. Typically there is no (significant) loss of consciousness and practically full recall. Observed are first-time hallucinations (visual, auditory, tactile, somesthetic, but not olfactory as in temporal lobe epilepsy) and signs of imbalance in the autonomic nervous system (loss of bladder control, ejaculation, profuse sweating, nausea). Only four of these men had previous psychiatric diagnoses (and then various ones) or abnormal EEGs at some time in their lives. Variety in prior diagnoses would be consistent with a seizure-like disorder, here specifically implicating an imbalance in functioning between limbic and frontal lobe systems. Clinical tests for the latter were prevailingly indicative of dysfunctioning. A detailed clinical analysis of the violent acts within their context suggests behaviors are analogous to certain limbic system mechanisms, especially the kindling phenomenon.

An aqueous solution of norfloxacin nicotinate (NFN) was administered to donkeys (Aquus asinus) intravenously (once at 10 mg/kg), intramuscularly and orally (both routes once at 10 and 20 mg/kg, and for 5 days at 20 mg/kg/day). Blood samples were collected at predetermined times after each treatment and urine was sampled after intravenous drug administration. Serum NFN concentrations were determined by microbiological assay. Intravenous injection of NFN over 45-60 s resulted in seizures, profuse sweating and tachycardia. The intravenous half-life (t1/2 beta) was 209 +/- 36 min, the apparent volume of distribution (Vd(area)) was 3.34 +/- 0.58 L/kg, the total body clearance (ClB) was 1.092 +/- 0.123 x 10(-2) mL/min/kg and the renal clearance (C1R) was 0.411 +/- 0.057 x 10(-2) mL/min/kg. Oral bioavailability was rather poor (9.6% and 6.4% for the 10 and 20 mg/kg doses respectively). Multiple oral treatments did not result in any clinical gastrointestinal disturbances. After intramuscular administration (20 mg/kg), serum NFN concentrations > 0.25 microgram/mL (necessary to inhibit the majority of gram-negative bacteria isolated from horses) were maintained for 12 h. The intramuscular bioavailability was 31.5% and 18.8% for the 10 and 20 mg/kg doses respectively. After multiple dosing some local swelling was observed at the injection site. About 40% of the intravenous dose was recovered in the urine as parent drug. The results of comprehensive haematological and blood biochemistry tests indicated no abnormal findings except elevation in serum CPK (creatine phosphokinase) values after multiple intramuscular dosing.(ABSTRACT TRUNCATED AT 250 WORDS)

Autonomic dysreflexia (AD) is a syndrome that consists of facial flushing, excessive sweating, nasal congestion, throbbing headache and paroxysmal hypertension which may occur in response to bladder distension in patients with spinal cord lesions above the T6 level. We report the case of a C2 quadriplegic patient who developed clinical features of AD along with cortical blindness and seizures after administration of meglumine (Hypaque) for diagnostic cystogram.

The aim of this study was to examine the characteristics of gamma-hydroxybutyrate (GHB) users, their GHB and other drug use patterns, and the harms associated with GHB use. Seventy-six GHB users were recruited and administered a structured interview on GHB use and related harms. GHB users appeared to be a stable, highly educated and well-functioning group. They had had extensive experience with a range of drugs, and GHB was typically used in conjunction with other drugs. Despite the fact that most GHB users had not had a long or extensive experience with GHB use, the proportion reporting significant negative side effects when using GHB was high (99% reported at least one), and the mean number of side effects ever experienced was 6.5. Notably, half (52%) reported becoming unconscious, 53% reported vomiting, 58% reported profuse sweating, and 8% reported having a fit or seizure. The high rate of problems reported by a group with limited use of this drug suggests that in a context of polydrug use, GHB use is associated with significant risks to users.

The authors reported a case of niclofolan intoxication occurred during the trial of clonorchiasis treatment. The case, a 15 years old Korean schoolboy, took niclofolan(Bilevon(R)) of total 473 mg(11 mg/kg) in 11 divided doses during 20 days. And the case suffered from neurologic symptoms such as severe headache, dizziness, nausea, vomiting, blurred vision, papilledema, retinal hemorrhage, an epsiode of seizure attack and elevated intracranial pressure, and hepatotoxic symptoms such as hepatomegaly, increased serum transaminases, and shoulder pain, excessive sweating and weight loss. Therapy was concentrated to the management of the elevated intracranial pressure. Hepatotoxic manifestations subsided within one month. The clinical signs related to elevated intracranial pressure persisted two months. Body weight regained after 2 months. And the symptoms of headache, dizziness and vomiting were complained intermittently until 4 months after onset. However, no subsequent clinical problems related with this episode has been noted until this record.

(1) When people who are physically dependent on alcohol stop drinking, they experience an alcohol withdrawal syndrome. The symptoms generally resolve spontaneously within a week, but more severe forms may be associated with generalised seizures, hallucinations and delirium tremens, which can be fatal. (2) We carried out a literature review in order to obtain answers to the following questions: how to predict or rapidly diagnose a severe alcohol withdrawal syndrome; how to prevent and treat this syndrome; how to manage severe forms; and how to deal with the risk of vitamin B1 deficiency. (3) The main risk factors for severe withdrawal syndrome are: chronic heavy drinking; a history of generalised seizures; and a history of delirium tremens. (4) Anxiety, agitation, tremor, excessive sweating, altered consciousness and hallucinations are signs of a severe withdrawal syndrome. (5) Individual support and effective communication seem to reduce the risk of severe withdrawal syndrome. (6) Oral benzodiazepines are the best-assessed drugs for preventing a severe alcohol withdrawal syndrome, particularly the risk of seizures. When given for a maximum of 7 days, the adverse effects are usually mild. (7) Clinical trials of other antiepileptics suggest they are less effective than benzodiazepines, and their addition to benzodiazepine therapy offers no tangible advantage. (8) Betablockers increase the risk of hallucinations, and clonidine increases the risk of nightmares, and the efficacy of these two drugs is not well documented. Neuroleptics increase the risk of seizures. There are no convincing data to support the use of magnesium sulphate or meprobamate (the latter carries a risk of serious adverse effects). Acamprosate, naltrexone and disulfiram are not beneficial in alcohol withdrawal. (9) Gradual withdrawal, i.e. ingestion of decreasing amounts of alcohol, has not been compared with other methods but is generally not recommended. (10) There are no specific recommendations on hydration. Note that excessive water-sodium intake carries a risk of pulmonary oedema in patients with heart disease. (11) As vitamin B1 deficiency is frequent and can lead to serious complications in alcohol-dependent patients, oral vitamin B1 supplementation is widely recommended, despite the absence of comparative trials. High doses must be used to compensate for poor absorption. Intravenous administration is best if patients have very poor nutritional status or severe complications such as Gayet-Wernicke encephalopathy (a medical emergency), even though rare anaphylactic reactions have been reported after vitamin B1 injection. (12) Planned alcohol withdrawal in specialised hospital units has been extensively studied. Outpatient withdrawal may be more appropriate for patients who are at low risk of developing severe withdrawal syndrome. (13) A large proportion of alcohol-dependent patients were excluded from trials of withdrawal strategies. These include elderly patients, patients with serious psychiatric or somatic disorders, and patients who are also dependent on other substances. (14) An oral benzodiazepine is the best-assessed treatment for a single episode of generalised seizures or hallucinations during alcohol withdrawal. (15) In randomised comparative trials benzodiazepines were more effective than neuroleptics in preventing delirium-related mortality. Currently, with appropriate fluid-electrolyte support, continuous monitoring of vital signs, and respiratory support if necessary, the mortality rate for delirium tremens is under 3%. (16) In practice, patients who are attempting to stop drinking alcohol need close personal support and communication, and a reassuring environment, as well as regular monitoring for early signs of a withdrawal syndrome; the latter may require benzodiazepine therapy.

This retrospective study aimed to examine the safety of botulinum toxin A (BoNT-A) treatment in a paediatric multidisciplinary cerebral palsy clinic. In a sample of 454 patients who had 1515 BoNT-A sessions, data on adverse events were available in 356 patients and 1382 sessions; 51 non-fatal adverse events were reported (3.3% of the total injections number, 8.7% of the patients). On five occasions, the adverse reactions observed in GMFCS V children were attributed to the sedation used (rectal midazolam plus pethidine; buccal midazolam) and resulted in prolongation of hospitalization. Of the reactions attributed to the toxin, 23 involved an excessive reduction of the muscle tone either of the injected limb(s) or generalized; others included local pain, restlessness, lethargy with pallor, disturbance in swallowing and speech production, seizures, strabismus, excessive sweating, constipation, vomiting, a flu-like syndrome and emerging hypertonus in adjacent muscles. Their incidence was associated with GMFCS level and with the presence of epilepsy (Odds ratio (OR) = 2.74 - p = 0.016 and OR = 2.35 - p = 0.046, respectively) but not with BoNT-A dose (either total or per kilogram). In conclusion, treatment with BoNT-A was safe; adverse reactions were mostly mild even for severely affected patients. Their appearance did not necessitate major changes in our practice.

Palpitations are a common symptom of presentation in medical practice. They are usually caused by cardiac arrhythmias, psychiatric problems or other miscellaneous causes, such as anaemia or endocrine causes. They are rarely due to autonomic seizures. We report a 55-year-old woman who presented at Sultan Qaboos University Hospital, Oman, with recurrent episodes of palpitations. Her associated symptoms included breathlessness and excessive sweating, followed by a sensation of dizziness. During subsequent episodes, she experienced symptoms of rising abdominal pain followed by a loss of consciousness. Positive electroencephalogram findings, as well as the response of the symptoms to antiepileptic drugs, were strongly suggestive of temporal lobe epilepsy as the possible diagnosis. The fact that the cardiac investigations, performed during an interictal period, were unremarkable also supports the hypothesis that the palpitations were linked to seizures. Epilepsy should be considered as a differential diagnosis of palpitations, especially if the palpitations are episodic.

Benign focal epilepsy with affective symptoms (BFEAS) is a rare childhood epilepsy syndrome essentially characterized by "epileptic attacks with affective symptoms of a terrifying type". Since the original description, approximately 50 cases have been reported. To our knowledge, however, none of the studies included video-EEG data. Herein, we detail the electroclinical features of a neurodevelopmentally normal 9-year-old boy with epilepsy since the age of 2 years. His seizure semiology essentially consisted of nocturnal focal seizures featuring abrupt fear and autonomic phenomena (such as excessive sweating, repeated swallowing, and coughing), associated with impaired consciousness. These seizures were often secondary generalized, and he had multiple episodes of convulsive status epilepticus. He has been seizure-free for the past year and a half on dual antiepileptic therapy with sulthiamine and valproate. His intellectual and social abilities are excellent (IQ of 116), although he does have difficulties particularly in language learning, and was recently diagnosed with phonological dyslexia with dysorthography. By presenting our patient's history and video-EEG, we intend to further detail the semiology of seizures with affective symptomatology. [Published with video sequence on www.epilepticdisorders.com].
