Abstract
PURPOSE We retrospectively analyzed the electroclinical features, treatment, and outcome of patients with Panayiotopoulos syndrome (PS) who presented with unusual clinical manifestations. METHOD A retrospective, descriptive, multicenter study was conducted evaluating 44 patients with PS who had seizures with an unusual semiology. Data from patients with PS seen at eight Argentine centers between April 2000 and April 2019 were collected. RESULTS Twelve patients (29.2%) had ictal syncope or syncope-like epileptic seizures. Three children (7.3%) had recurrent episodes of vomiting. Four patients (9.7%) presented with urinary incontinence associated with autonomic signs and consciousness impairment. One child had hiccups with autonomic manifestations followed by eye deviation. One boy had episodes of laughter with autonomic symptoms followed by loss of consciousness. Six patients (14.6%) had hyperthermia without acute febrile illness with autonomic symptoms as the first manifestation. Six others (14.6%) had focal motor seizures characterized by eye and head deviation in four and eyelid blinking in two. Four patients (9.7%) had ictal headache as the initial manifestation followed by nausea and vomiting. Two children (4.8%) had their first seizure while asleep associated with cardiorespiratory arrest. Two children (4.8%) had oral automatisms, such as sucking and chewing. In two children (4.8%) coughing was the initial manifestation followed by emetic symptoms. One patient (2.3%) had vertigo with a sensation of fear, with eye deviation and unresponsiveness. One child started with continuous spikes and waves during slow sleep, behavior disturbances, and emetic symptoms. CONCLUSION In this study, evidence of the existence of unusual clinical cases of PS with typical EEG patterns was found. Outcome was excellent.

Abstract
We aimed to explore the link between NREM sleep and epilepsy. Based on human and experimental data we propose that a sleep-related epileptic transformation of normal neurological networks underlies epileptogenesis. Major childhood epilepsies as medial temporal lobe epilepsy (MTLE), absence epilepsy (AE) and human perisylvian network (PN) epilepsies - made us good models to study. These conditions come from an epileptic transformation of the affected functional systems. This approach allows a system-based taxonomy instead of the outworn generalized-focal classification. MTLE links to the memory-system, where epileptic transformation results in a switch of normal sharp wave-ripples to epileptic spikes and pathological high frequency oscillations, compromising sleep-related memory consolidation. Absence epilepsy (AE) and juvenile myoclonic epilepsy (JME) belong to the corticothalamic system. The burst-firing mode of NREM sleep normally producing sleep-spindles turns to an epileptic working mode ejecting bilateral synchronous spike-waves. There seems to be a progressive transition from AE to JME. Shared absences and similar bilateral synchronous discharges show the belonging of the two conditions, while the continuous age windows - AE affecting schoolchildren, JME the adolescents - and the increased excitability in JME compared to AE supports the notion of progression. In perisylvian network epilepsies - idiopathic focal childhood epilepsies and electrical status epilepticus in sleep including Landau-Kleffner syndrome - centrotemporal spikes turn epileptic, with the potential to cause cognitive impairment. Postinjury epilepsies modeled by the isolated cortex model highlight the shared way of epileptogenesis suggesting the derailment of NREM sleep-related homeostatic plasticity as a common step. NREM sleep provides templates for plasticity derailing to epileptic variants under proper conditions. This sleep-origin explains epileptiform discharges' link and similarity with NREM sleep slow oscillations, spindles and ripples. Normal synaptic plasticity erroneously overgrowing homeostatic processes may derail toward an epileptic working-mode manifesting the involved system's features. The impact of NREM sleep is unclear in epileptogenesis occurring in adolescence and adulthood, when plasticity is lower. The epileptic process interferes with homeostatic synaptic plasticity and may cause cognitive impairment. Its type and degree depends on the affected network's function. We hypothesize a vicious circle between sleep end epilepsy. The epileptic derailment of normal plasticity interferes with sleep cognitive functions. Sleep and epilepsy interconnect by the pathology of plasticity.

Abstract
The aim of the study was to evaluate the demographic, clinical, and EEG characteristics of patients with Panayiotopoulos syndrome (PS) and the course of their illness. Thirty-eight patients followed up with a diagnosis of PS between January 2011 and December 2013 were evaluated. We found high rates of personal history of febrile convulsions, breath-holding spells, and family history of febrile convulsions, afebrile convulsion/epilepsy, migraine, and breath-holding spells. Seizures started before the age of eight in 87% of the patients, and the mean age at seizure onset was 4.6 years. Seizures were sleep-related in 81.5%, and autonomic status was seen in a third of the patients. The number of seizures was between 2 and 10 in 66% of the patients. The most common symptoms were ictus emeticus, eye/head deviation, and altered consciousness. Rolandic features were seen in 26% of the patients, and visual symptoms in 5%. Multifocal epileptiform discharges on EEG were identified in 84% of the patients. Two or more antiepileptic drugs were required in only 13% of the patients. Evolution to electrical status epilepticus in sleep and Gastaut-type epilepsy were seen in patients with more than ten seizures. The high rates of febrile convulsions, afebrile convulsions/epilepsy, migraine, and breath-holding spells in the patients and families suggest the importance of genetic factors and, perhaps, a common pathogenesis. However, the high rates of febrile convulsions and breath-holding spells in patients can be related to a misdiagnosis because of the similar symptoms. Despite its disturbing symptoms, PS is a benign epileptic syndrome requiring multiple antiepileptic drug use only in a small proportion of patients.

Abstract
The diagnosis of benign epilepsy syndrome should meet the following criteria: age-related and self-limited; good response to medication; and no obvious neurological sequelae after seizure. However, the current concept of benign epilepsy syndrome has been challenged because of the advancements in genetic studies, neuroimaging, and molecular techniques. Many studies have revealed that the prevalence of behavioral problems and learning difficulties as well as subtle cognitive deficits is higher among patients with benign epilepsy, compared with the normal population. Here, we review updated results of these studies to show the latest and broad comprehensive knowledge of benign epilepsy in children.

Abstract
PURPOSE The objective of this retrospective study was to identify clinical and EEG features in children with occipital epilepsy that predict MR imaging abnormalities and seizure outcome. METHODS Patients with clinical and/or EEG features indicating occipital lobe involvement were identified from the epilepsy database at a tertiary children's hospital. The clinical and EEG features were analyzed to identify the most important predictors of abnormal MR imaging and seizure outcome. RESULTS Sixty-six patients were identified: 21 had symptomatic epilepsy with abnormal MR imaging; 12 patients had probable symptomatic epilepsy based on an abnormal neurological exam; 33 patients had normal neurological development, normal neurological examination and normal neuroimaging. Twenty-two of these 33 patients satisfied criteria for idiopathic occipital syndromes: Panayiotopoulos syndrome (9 patients), Gastaut type idiopathic childhood occipital epilepsy (12 patients) and idiopathic photosensitive occipital epilepsy (1 patient). Eleven patients could not be classified. Early age of seizure onset and an abnormal neurological examination were significant predictors of abnormal MR imaging. None of the variables examined were strong predictors of seizure outcome. CONCLUSION Early age of seizure onset and an abnormal neurological examination are the best predictors of abnormal MR imaging in children with epilepsy with occipital features.

Abstract
The purpose of this review is to provide guidance for appropriate diagnosis and management of idiopathic childhood occipital epilepsy of Gastaut. The typical clinical features are visual seizures that typically consist of brief elementary visual hallucinations, which are mainly multicolored and circular. Ictal blindness and deviation of the eyes are also common symptoms. The seizures are usually frequent and diurnal. The electroencephalography is the only investigation with abnormal results, showing occipital spikes and often occipital paroxysms demonstrating fixation-off sensitivity. Brain magnetic resonance imaging is used to exclude symptomatic occipital epilepsy. Patients usually respond well to antiepileptic medication and about two-thirds remit by the age of 16 years. Idiopathic childhood occipital epilepsy of Gastaut is frequently misdiagnosed as migraine with visual aura, acephalgic, or basilar migraine. Differentiation from symptomatic occipital epilepsy, particularly when children are otherwise normal, can be difficult. Most children need prophylactic antiepileptic medication.

Abstract
Prognostic factors for frequent seizure recurrences were studied in patients with Panayiotopoulos syndrome. The subjects were 79 children fulfilling the criteria of Panayiotopoulos syndrome who were monitored for longer than 2 years. Medical records and electroencephalograms were analyzed retrospectively. The total number of seizures in each patient at the final follow-up ranged from 1 to 22. The 79 patients were classified into three groups: typical Panayiotopoulos syndrome (seizure recurrence = 1-5 times, n = 45), borderline (6-9 times, n = 16), and atypical (>10 times, n = 18). Data analyzed included family history of seizure disorders, peri- and postnatal complications, previous seizure histories, age at epilepsy onset, clinical seizure manifestations, the frequency of status epilepticus, interictal electroencephalographic patterns, and the possible association of neurobehavioral disorders among the three groups. An association with pre-existing neurobehavioral disorders was significantly more frequent in the atypical than in the typical group (P < 0.05), but not significantly different between the typical and borderline or between the borderline and atypical patients (P> 0.05). In patients with Panayiotopoulos syndrome and pre-existing mild neurobehavioral disorders, seizures tend to be pharmacoresistant and to repeat more than 10 times. However, all patients experience seizure remission by 12 years of age, and should not be evaluated for surgery.

Abstract
Panayiotopoulos syndrome is a common and benign childhood autonomic epilepsy of debated localization. Although officially considered as occipital epilepsy, this is most likely of multifocal origin. Ictal electroencephalography is the gold standard of seizure localization, but in Panayiotopoulos syndrome, because patients have single or rare seizures, only 7 cases with ictal electroencephalography have been reported. Ictal onsets show variable anterior and more often posterior locations. We describe an 8-year-old girl with 5 nocturnal autonomic seizures typical of Panayiotopoulos syndrome from age 4. The last seizure was captured with electroencephalography and showed a diffuse onset of the ictal discharge, whereas various interictal electroencephalography had infrequent multifocal spikes. This case contributes to the understanding of the pathophysiology of Panayiotopoulos syndrome in favor of a diffuse and multifocal cortical epileptogenicity that triggers an unstable central autonomic nervous system solely or prior to the focal cortical symptoms.
