RESUMO
OBJECTIVES: To investigate the clinical features of developmental and/or epileptic encephalopathy with spike-and-wave activation in sleep (D/EE-SWAS), its electrographic characteristics, and etiology and to compare the effects of different treatment strategies on the outcomes using a Saudi Arabian database. METHODS: This multicenter study included children with D/EE-SWAS who were evaluated between 2010 and 2020 at 11 tertiary centers. Data were collected on their baseline clinical features, etiologies, and treatment modalities. Seizure reduction, spike-wave index, and cognitive state were examined as potential therapeutic outcomes. RESULTS: Ninety-one children were diagnosed with D/EE-SWAS, with a median age of 7 years (IQR: 3-5) and an almost equal sex distribution. The average age at which epilepsy was diagnosed was 3 years (IQR: 5-2). A genetic/metabolic etiology was found in 35.1% of the patients, and a structural etiology was found in 27.4%. Children with underlying genetic/metabolic diseases exhibited an earlier seizure onset (P = 0.001) than children with other etiologies. Benzodiazepines (76.6%) were the most common treatment, followed by steroids (51.9%). Sodium valproate (75%) was the most frequently used antiseizure medication, followed by levetiracetam (64.9%). Children with a later seizure onset were more likely to have better clinical responses (P = 0.046), EEG responses (P = 0.012), and cognitive outcomes (P = 0.006) than children with an earlier onset. Moreover, better seizure response and electrographic response were seen in patients with bilateral interictal discharges on the EEG than otherwise. Children had a higher likelihood of both clinical and electrographic improvement with combination therapy of benzodiazepines (P = 0.001) and steroids (P = 0.001) than with other therapies. SIGNIFICANCE: This study shows a higher prevalence of genetic/metabolic causes and suggests the superior efficacy of combination therapy with steroids and benzodiazepines in D/EE-SWAS. Prospective studies that strictly assess the treatment protocols and outcomes are needed.

BACKGROUND: The presence of cerebral astrocytic inclusions recently has been described in a subset of children with early-onset refractory epilepsy, with or without structural brain malformations, and varying degrees of developmental delay. METHODS: We describe two new individuals with epilepsy with astrocytic inclusions and suggest that in some children this disorder may represent a unique hemispheric epilepsy. We review previously reported individuals with epilepsy with astrocytic inclusions. RESULTS: Two children with early onset epilepsy with astrocytic inclusions had refractory clusters of epileptic spasms, developmental delay, abnormal neuroimaging, and hemispheric or diffuse interictal epileptiform discharges. In both children, the initial focal resection of the putative epileptogenic zone was unsuccessful and pathology failed to show astrocytic inclusions. Subsequently, both children underwent functional hemispherectomy due to ongoing clusters of epileptic spasms, and the presence of multilobar astrocytic inclusions was demonstrated. Postoperatively, both children have remained seizure free in the short-term with improved development. CONCLUSIONS: We highlight that functional hemispherectomy may be required for seizure control in a select subset of children with clusters of epileptic spasms, astrocytic inclusions, and global developmental delay. Given the small number of documented patients, however, ongoing collaboration is needed to better understand the pathophysiology of this condition and determine the optimal way to diagnose and manage these children.

Cingulate epilepsy is a rare form of epilepsy. Seizures from the anterior cingulate may present with mood change, fear, hypermotor activity, and autonomic signs, while posterior cingulate seizures resemble temporal lobe seizures. We describe a child with cingulate epilepsy who experienced unpleasant/painful sensory phenomenon. The sensations were described as spiders crawling on his forehead/right leg, ladybugs causing right ear pain and bees stinging his head/right extremities. Unpleasant sensory phenomenon/pain are rarely reported in cingulate epilepsy. Recognizing the role of the cingulate in producing pain/unusual sensory phenomenon is important, and may have localizing value when evaluating children for epilepsy surgery.
