Early onset benign occipital susceptibility syndrome (EBOSS) is a recently delineated form of idiopathic childhood partial epilepsy, which is still not recognized by the International League Against Epilepsy as a distinct epileptic syndrome. It occurs with generally nocturnal, prolonged partial seizures, which can become a status epilepticus. The seizures are characterized by tonic eye deviation, vomiting, progressive impairment of consciousness, autonomic symptoms, frequent progression to hemiconvulsions or generalized tonic-clonic seizures. Age at onset is usually between 3 and 7 years, frequency is remarkably low (often a single seizure), and outcome is excellent. Interictal EEG shows occipital paroxysms with fixation-off sensitivity. We present the first video-EEG documentation of a typical case of EBOSS and discuss the clinical and EEG features of the case. The documentation is useful for a better definition of the syndrome and also permits a differential diagnosis with respect to other occipital forms of epilepsy and other sleep related paroxysmal disorders.

Three unusual cases of salivary gland enlargement and hypersialosis in the dog that responded to anticonvulsant therapy are reported. Presenting complaints included weight loss, hypersalivation, retching and vomiting of several weeks' duration. Two dogs were presented with enlarged painful mandibular salivary glands. The third dog exhibited bizarre behaviour (including jaw chattering) and developed enlarged painful mandibular salivary glands during hospitalisation. Fine needle aspirate cytology and biopsies from the enlarged salivary glands revealed no significant pathological changes. In one dog, an electroencephalogram revealed changes consistent with epilepsy. Hypersialism and salivary gland enlargement resolved completely during phenobarbital administration in all cases. Two dogs were successfully weaned off treatment six months after diagnosis. The remaining dog relapsed after eight months, but normalised with the addition of oral potassium bromide. It is hypothesised that the syndrome idiopathic hypersialosis may in fact be an unusual form of limbic epilepsy.

We report a 36-year-old woman, without any past or family histories of epilepsy, who presented frequent vomiting and generalized convulsions. About 4 h before the convulsion, she had consumed approximately 70-80 gingko nuts, seeds of Gingko biloba, in an attempt to improve her health. It is important to know that convulsion may be induced if a large amount of gingko nuts is consumed. The neurotoxicity of gingko nuts, particularly their convulsion-inducing effect, should be recognized.

A longitudinal prospective approach was used to investigate clinical correlations of interictal occipital paroxysms with or without fixation-off sensitivity (FOS). Occipital paroxysms were recorded in the electroencephalograms (EEGs) of 76 children with heterogeneous clinical conditions including seizures in 39 patients. Occipital paroxysms with FOS (42 patients ) were only fractionally more frequent than non-FOS (34 patients ) and were not specific of any clinical condition. Although present and FOS-related in all 11 children with benign childhood epilepsies with occipital paroxysms (CEOP), they were also frequently encountered in symptomatic occipital epilepsy. The differentiation of CEOP from other syndromes established on clinical grounds could also be aided by the analysis of background EEG activity that was frequently significantly more abnormal in symptomatic than CEOP. Clinical characteristics and ictal seizure semiology as well as follow-up clearly distinguish two type of idiopathic CEOP syndromes: (1) early onset type or Panayiotopoulos syndrome characterized by excellent prognosis and rare, prolonged nocturnal seizures with tonic deviations of the eyes and vomiting, and (2) late onset or Gastaut type showing a common ictal visual symptomatology, co-occurrence of migraine, diurnal complex partial seizures and less favourable EEG-clinical prognosis.

The lack of a common, widely acceptable criterion for the definition of trivial, minor, or mild head injury has led to confusion and difficulty in comparing findings in published series. This review proposes that acute head-injured patients previously described as minor, mild, or trivial are defined as "mild head injury," and that further groups are recognized and classified as "low-risk mild head injury," "medium risk mild head injury," or "high-risk mild head injury." Low-risk mild injury patients are those with a Glasgow Coma Score (GCS) of 15 and without a history of loss of consciousness, amnesia, vomiting, or diffuse headache. The risk of intracranial hematoma requiring surgical evacuation is definitively less than 0.1:100. These patients can be sent home with written recommendations. Medium risk mild injury patients have a GCS of 15 and one or more of the following symptoms: loss of consciousness, amnesia, vomiting, or diffuse headache. The risk of intracranial hematoma requiring surgical evacuation is in the range of 1-3:100. Where there is one computed tomography (CT) scanner available in an area for 100,000 people or less, a CT scan should be obtained for such patients. If CT scanning is not so readily available, adults should have a skull x-ray and, if this shows a fracture, should be moved to the "high-risk" category and undergo CT scanning. High-risk mild head injury patients are those with an admission GCS of 14 or 15, with a skull fracture and/or neurological deficits. The risk of intracranial hematoma requiring surgical evacuation is in the range 6-10:100. If a CT scan is available for 500,000 people or less, this examination must be obtained. Patients with one of the following risk factors--coagulopathy, drug or alcohol consumption, previous neurosurgical procedures, pretrauma epilepsy, or age over 60 years--are included in the high-risk group independent of the clinical presentation.

Twenty-six patients were studied who had the clinical and electroencephalographic features of benign childhood epilepsy with occipital paroxysms (BCEOP) as defined by the Commission of the International League Against Epilepsy (ILAE). Twelve patients were characterized as having early-onset benign childhood occipital seizures (EBOS) susceptible syndrome, as described by Panayiotopoulos, and 14 patients had late onset childhood idiopathic occipital seizures (LOS). Patients with symptomatic epilepsy and whose EEGs exhibited occipital spikes were excluded. The age of onset of the EBOS group ranged from 2.6 to 9.4 years (mean: 4.9+/-1.7 years), which was significantly younger than the LOS group (range: 4-12 years, mean:8.4+/-2.5 years). Both sexes were equally affected. The patients in the EBOS group had less frequent and longer seizures, ictal vomiting, more frequent deviation of the eyes, adversive seizures and more frequent nocturnal and secondary generalized seizures (P<0.05). By comparison, patients in the LOS group had a higher incidence of seizures, shorter duration of seizures and more frequent diurnal onset (P<0.01); also, although not statistically significant, the LOS group had more frequent visual hallucinations and headaches. The EEG topography in both groups showed at either side of occipital area typical paroxysms that were unilateral or bilaterally synchronous. Neither group had dipoles according to scalp voltage mapping. The clinical prognoses were favorable for both groups. To distinguish EBOS from LOS, detailed description of the age of onset, motor symptoms, visual symptoms, presence of eye deviation and diurnal or nocturnal occurrence are essential.

Early-onset benign childhood occipital seizure susceptibility syndrome (EBOSS) recently described by Panayiotopoulos, is an early-onset variant of benign childhood epilepsy with occipital paroxysms. EBOSS is characterized by partial seizures that are predominantly manifested at night and associated with deviation of the eyes, vomiting and impairment of consciousness, but without ictal visual symptoms or postictal headache. The clinical features of our case were consistent with those of EBOSS, and we therefore diagnosed the patient as having a typical form of EBOSS. Neuroimaging by CT, MRI and MR angiography did not reveal a focal lesion. Interictal single photon emission computed tomography (SPECT) revealed decreased cerebral blood flow in the right occipital region corresponding to the epileptogenic focus shown on EEG. It remains unclear whether our finding on SPECT reflects secondary hypoperfusion due to minor morphological abnormality or immediate functional hypoperfusion. No reference to SPECT in a case of EBOSS has appeared in the literature to date. This report provides a better understanding of benign childhood epileptic syndromes with occipital spikes.

Among the idiosyncratic reactions related to VPA, pancreatitis is the most rare and less remembered even though its potentially fatal course. We report the case of a 5 year-old boy with epilepsy treated with VPA 40 mg/kg/day associated with CBZ 20 mg/kg/day and PB 3 mg/kg/day, admitted for vomiting, abdominal pain, low grade fever, abdominal tension and amylasis of 288 UI. On evolution presented upper digestive hemorrhage, shock and amylasis of 564 UI. The patient was submitted to exploratory laparotomy with findings of hemorrhagic ascitis, retroperitoneal hematoma, increased volume of pancreas with edema and hemorrhage leading to diagnosis of necro-hemorrhagic pancreatitis and a fatal course. Pancreatic complications are well known complications related to VPA treatment and may vary between asymptomatic hyperamilasemy to fatal acute pancreatitis. The characteristics of our patient correlates with the data on literature: we found 7 similar cases reported, 4 of which died.

Autonomic symptoms frequently occur during epileptic seizures either as an accompaniment to other seizure symptoms or as the predominant seizure manifestation. They do not represent simple reactions to motor manifestations of seizures, but are mediated by an activation of the central autonomic network. Autonomic symptoms can be divided into cardiovascular changes, respiratory manifestations, gastrointestinal symptoms, cutaneous manifestations, pupillary symptoms, genital and sexual manifestations as well as urinary symptoms. Due to a hemispheric-specific representation of the central autonomic network, certain autonomic symptoms may provide lateralizing and sometimes localizing information on the seizure onset zone, although some of these signs may appear as a result of discharge spreading. Autonomic symptoms indicating a seizure onset in the non-dominant hemisphere include ictal vomiting and retching, spitting automatisms and ictal urinary urge. Autonomic symptoms range from subtle seizure manifestations which become apparent only during meticulous seizure analysis, to severe, sometimes life-threatening events. Cardiovascular and respiratory autonomic symptoms are discussed as the mechanisms underlying sudden unexplained death in epilepsy. When autonomic symptoms represent the sole seizure manifestation, they can pose problems for differential diagnosis of various non-epileptic conditions. Finally, autonomic seizure symptoms open a unique window on the functional organization of the central autonomic network and on brain function in general. (Published with videosequences.)

We report, on two, school-age girls with clinical and electroencephalographic features of early onset childhood epilepsy with occipital paroxysms (CEOP) of the "Panayiotopoulos type" that showed atypical evolution. Neurological examination and brain imaging were normal in both. One child presented at age 2.5 years episodes of oculocephalic deviation, and ictal vomiting during nocturnal sleep. The EEG showed left occipital spikes during wakefulness and sleep. One year later, frequent inhibitory seizures appeared in the lower limbs causing, "pseudoataxic gait". At the same time she presented with behavioral disturbances and aphasia. EEG showed bilateral spike-waves while awake and continuous spike-waves during slow sleep (CSWSS). After switching AEDs to benzodiazepines, control of seizures along with improvement of behavior, and partial restoration of cognitive functions were achieved. The CSWSS disappeared and the last EEG at age 8 years only showed only isolated right occipital spikes. The other girl had a personal and familial history of febrile seizures. At 4 years of age she presented the first non-febrile seizures during sleep, with oculocephalic deviation and ictal vomiting, followed by a generalized tonic-clonic seizure. Partial control of seizures was obtained with antiepileptic drugs. At age 7, the child began to have weekly episodes of oculocephalic version, occasionally with secondary generalization. Repeated inhibitory seizures and absences also appeared. EEG showed frequent bilateral spikes occupying predominantly the posterior regions while awake, and CSWSS. At 7.5 years the same electro-clinical picture persisted. Ethosuximide was added to sodium valproate and clobazam. Fifteen days later, the seizures disappeared and the EEG showed less frequent bilateral occipital spikes. She is now 9 years old and she has been seizure-free for 18 months. Her present neuropsychological profile shows mild mental retardation. The two children with typical electroclinical features of "Panayiotopoulos Type" CEOP developed an atypical evolution which, to our knowledge, has not been described previously.
