Object: Few data are available concerning efficacy and safety of surgery for catastrophic epilepsy in the first 6 months of life.
Methods: The authors retrospectively analyzed epilepsy surgeries in 15 infants ranging in age from 1.5 to 6 months (median 4 months) and weight from 4 to 10 kg (median 7 kg) who underwent anatomical (4 patients) or functional (7 patients) hemispherectomy, or frontal (1 patient), frontoparietal (2 patients), or parietooccipital (1 patient) resection for life-threatening catastrophic epilepsy due to malformation of cortical development.
Results: No patient died. Intraoperative complications included an acute ischemic infarction with hemiparesis in our youngest, smallest infant. The most frequent complication was blood loss requiring transfusion, which was encountered in every case. The estimated blood loss was 3-214% (median 63%) of the total blood volume. At maximum follow-up of 6-121 months (median 60 months), 46% were seizure free.
Conclusions: Epilepsy surgery may be effective in young infants as it is in older children. However, intraoperative blood loss and risk of permanent postoperative neurological deficits present significant challenges.

Phenytoin toxicity caused by a drug-to-drug interaction between phenytoin and antitubercular therapy.

Phenytoin is one of the most used antiepileptic drugs. Isoniazid, a first-line antitubercular drug, blocks the CYP2C19 enzyme, preventing phenytoin from being metabolised. Concomitant use of phenytoin and isoniazid predisposes to phenytoin toxicity.

Background: Functional MRI (fMRI) has proven valuable in presurgical planning for people with brain tumors. However, it is underutilized for patients with epilepsy, likely due to less data on its added clinical value in this population. We reviewed clinical fMRI referrals at the QEII Health Sciences Center (Halifax, Nova Scotia) to determine the impact of fMRI on surgical planning for patients with epilepsy.

Article Synopsis
- - Despite advances in epilepsy prediction through machine learning, traditional models struggle with dynamic data in real-time clinical settings due to a phenomenon known as catastrophic forgetting (CF), where previously learned information is lost as new data is introduced.
- - The paper presents a continual learning strategy called Memory Projection (MP) that integrates core algorithms to prevent CF, allowing models to adapt to individual patient EEG data while maintaining performance and knowledge transfer.
- - Experimental results indicate that MP achieves low forgetting rates (under 5% for accuracy and sensitivity) even when learning from diverse datasets, outperforming other continual learning methods while requiring minimal storage and computational resources, showcasing its practical application for seizure prediction.
Did pediatric drug development advance epilepsy treatment in young patients? It is time for new research goals.

Article Synopsis
- Modern drugs have greatly improved treatment for epilepsy, which affects people of all ages, but drug development for young patients has lagged since the thalidomide disaster.
- The misconception that antiseizure medications (ASMs) must undergo separate testing for those under 18 has led to unnecessary pediatric clinical research and hindered progress in meaningful research goals.
- The focus should shift from proving ASMs' effectiveness to preventing seizures and brain damage in young patients, and optimizing the use of these medications.
Disconnective hemispherotomy: technique and operative highlights.

Hemispherectomy is an effective procedure used in the treatment of drug-resistant hemispheric epilepsy, especially in the pediatric population. A number of resective and disconnective techniques are used, and selection of surgical strategy is paramount to achieving successful results. Notably, disconnective (or functional) hemispherotomy maximizes the benefits of safe, surgical disconnection while minimizing hemispheric tissue resection, thereby avoiding some of the perioperative factors contributing to morbidity in traditional anatomical hemispherectomy procedures.
