OBJECTIVES:
Vagus nerve stimulation (VNS) is a neuromodulative therapeutic technique for patients with drug-resistant epilepsy who are not suitable for resection or who have experienced a failed resection. This study aims to explore the efficacy and safety of VNS in patients with refractory epilepsy, and to analyze the influential factors for the efficacy.
METHODS:
A retrospective review of clinical data were conducted for 35 patients, who were treated for refractory epilepsy through VNS surgery in the Department of Neurosurgery, Xiangya Hospital, Central South University from April 2016 to August 2019. All patients were analyzed in terms of the clinical and follow-up data.
RESULTS:
After a mean follow-up of 26 months (6-47 months), outcome was as follows: 7 patients were MuHugh class I, 13 patients were MuHugh class II, 8 patients were MuHugh class III, and 7 patients were MuHugh class IV-V. The total efficacy rate in the short duration group was significantly higher than that in the long duration group (77.8% vs 50.0%,
CONCLUSIONS
VNS is a safe and effective option in treating patients with refractory epilepsy, especially for those with short duration.

In Japan, because the most common site of drowning among patients with epilepsy is the bathtub, showering is generally recommended as an alternative to bathing. We herein report a case involving a female patient with epilepsy who drowned while showering. She had been diagnosed with epilepsy approximately 25 years previously, and her condition had progressed to refractory epilepsy. Carbamazepine, levetiracetam, lamotrigine, clobazam, and perampanel were prescribed daily. One day while showering, the patient was found lying with her face immersed in water that had accumulated on the floor of the bathtub. A forensic autopsy revealed water in the stomach, trachea, and proximal regions of both lung bronchi as well as white and red foam on the pharynx and larynx. A total of 1.9 μg/mL of lamotrigine, 0.14 μg/mL of carbamazepine, and 0.069 μg/mL of perampanel were detected in the patient's blood. The patient's cause of death was determined to be drowning due to an epileptic seizure. Although the patient was prescribed five types of antiepileptic medication, only three were detected in her blood. The current case demonstrates that drowning can occur while showering, suggesting that it is unsafe for patients with medication nonadherence. To prevent unintentional deaths in the bathroom, we recommend that patients with epilepsy maintain high adherence to all prescriptions and are supervised by a family member, even when showering. The current case is the first autopsy report of a patient with epilepsy who drowned while showering.

4.A Primer on Magnetic Resonance-Guided Laser Interstitial Thermal Therapy for Medically Refractory Epilepsy

Epilepsy surgery that eliminates the epileptogenic focus or disconnects the epileptic network has the potential to significantly improve seizure control in patients with medically intractable epilepsy. Magnetic resonance-guided laser interstitial thermal therapy (MRgLITT) has been an established option for epilepsy surgery since the US Food and Drug Administration cleared the use of MRgLITT in neurosurgery in 2007. MRgLITT is an ablative stereotactic procedure utilizing heat that is converted from laser energy, and the temperature of the tissue is monitored in real-time by MR thermography. Real-time quantitative thermal monitoring enables titration of laser energy for cellular injury, and it also estimates the extent of tissue damage. MRgLITT is applicable for lesion ablation in cases that the epileptogenic foci are localized and/or deep-seated such as in the mesial temporal lobe epilepsy and hypothalamic hamartoma. Seizure-free outcomes after MRgLITT are comparable to those of open surgery in well-selected patients such as those with mesial temporal sclerosis. Particularly in patients with hypothalamic hamartoma. In addition, MRgLITT can also be applied to ablate multiple discrete lesions of focal cortical dysplasia and tuberous sclerosis complex without the need for multiple craniotomies, as well as disconnection surgery such as corpus callosotomy. Careful planning of the target, the optimal trajectory of the laser probe, and the appropriate parameters for energy delivery are paramount to improve the seizure outcome and to reduce the complication caused by the thermal damage to the surrounding critical structures.

5.Protein-Losing Enteropathy as a Complication of the Ketogenic Diet.

The ketogenic diet is an effective treatment for the patients with intractable epilepsy, however, the diet therapy can sometimes be discontinued by complications. Protein–losing enteropathy is a rarely reported serious complication of the ketogenic diet. We present a 16-month-old Down syndrome baby with protein-losing enteropathy during the ketogenic diet as a treatment for West syndrome. He suffered from diarrhea, general edema and hypoalbuminemia which were not controlled by conservative care for over 1 month. Esophagogastroduodenoscopy and stool alpha-1 antitrypsin indicated protein-losing enteropathy. Related symptoms were relieved after cessation of the ketogenic diet. Unexplained hypoalbuminemia combined with edema and diarrhea during ketogenic suggests the possibility of protein-losing enteropathy, and proper evaluation is recommended in order to expeditiously detect it and to act accordingly.

6.Glucose transport 1 deficiency presenting as infantile spasms with a mutation identified in exon 9 of SLC2A1.
Korean Journal of Pediatrics 2016;59(Suppl 1):S29-S31
Glucose transport 1 (GLUT-1) deficiency is a rare syndrome caused by mutations in the glucose transporter 1 gene (SLC2A1) and is characterized by early-onset intractable epilepsy, delayed development, and movement disorder. De novo mutations and several hot spots in N34, G91, R126, R153, and R333 of exons 2, 3, 4, and 8 of SLC2A1 are associated with this condition. Seizures, one of the main clinical features of GLUT-1 deficiency, usually develop during infancy. Most patients experience brief and subtle myoclonic jerk and focal seizures that evolve into a mixture of different types of seizures, such as generalized tonic-clonic, absence, myoclonic, and complex partial seizures. Here, we describe the case of a patient with GLUT-1 deficiency who developed infantile spasms and showed delayed development at 6 months of age. She had intractable epilepsy despite receiving aggressive antiepileptic drug therapy, and underwent a metabolic workup. Cerebrospinal fluid (CSF) examination showed CSF-glucose-to-blood-glucose ratio of 0.38, with a normal lactate level. Bidirectional sequencing of SLC2A1 identified a missense mutation (c.1198C>T) at codon 400 (p.Arg400Cys) of exon 9.
