Overcoming barriers to the management of seizure clusters: ease of use and time to administration of rescue medications.

INTRODUCTION: Patients with epilepsy can experience seizure clusters (acute repetitive seizures), defined as intermittent, stereotypic episodes of frequent seizure activity that are distinct from typical seizure patterns. There are three FDA-approved rescue medications, diazepam rectal gel, midazolam nasal spray, and diazepam nasal spray, that can be administered to abort a seizure cluster in a nonmedical, community setting. Despite their effectiveness and safety, rescue medications are underutilized, and patient/caregiver experiences and perceptions of ease of use may constitute a substantial barrier to greater utilization. AREAS COVERED: The literature on rescue medications for seizure clusters is reviewed, including the effectiveness and safety, with an emphasis on ease and timing of treatment and associated outcomes. Barriers to greater utilization of rescue medication and the role of seizure action plans are discussed. EXPERT OPINION: Intranasal rescue medications are easier to use and can be administered more rapidly than other routes (rectal, intravenous). Importantly, rapid administration of intranasal rescue medications has been associated with shorter durations of seizure activity as compared with rectal/intravenous routes. Intranasal rescue medications are also easy to use and socially acceptable. These factors potentially remove or reduce barriers to use and optimize the management of seizure clusters.

A consensus-based approach to patient safety in epilepsy monitoring units: recommendations for preferred practices.

Patients in an epilepsy monitoring unit (EMU) with video-EEG telemetry have a risk for seizure emergencies, injuries and adverse events, which emphasizes the need for strategies to prevent avoidable harm. An expert consensus process was used to establish recommendations for patient safety in EMUs. Workgroups analyzed literature and expert opinion regarding seizure observation, seizure provocation, acute seizures, and activity/environment. A Delphi methodology was used to establish consensus for items submitted by these workgroups. Fifty-three items reached consensus and were organized into 30 recommendations. High levels of agreement were noted for items pertaining to orientation, training, communication, seizure precautions, individualized plans, and patient/family education. It was agreed that seizure observation should include direct observation or use of closed-circuit camera. The use of continuous observation was strongest in patients with invasive electrodes, at high risk for injury, or undergoing AED withdrawal. This process provides a first step in establishing EMU safety practices.

Improving Health Outcomes in Vulnerable Populations: The Medical-Legal Partnership-Colorado's Experience.

Medical-legal partnerships (MLPs) add legal professionals, trained specifically to tackle health-related social needs (HRSN), to the health care team. We evaluated the impact on health outcomes and health care utilization of a MLP housed in a large federally qualified health center in Colorado (MLP-CO). Clients screened for I-HELP (Income, Housing, Employment, Legal status, Personal stability) needs were surveyed at baseline and six months post-enrollment. Reasons for legal aid were legal immigration status (46.5%), income (30.8%), personal/family stability (14.8%), housing (4.8%), and education (1.2%). Overall, 61.4% attributed great/moderate improvements in their health care experience to the MLP-CO. Statistically significant improvements were noted for days with poor physical/mental health, and feelings of stress/worry. There was a reduction in emergency department visits, hospitalization days, and missed appointments, but only the latter was statistically significant. In conclusion, MLPs are a promising innovation to achieve the Institute for Healthcare Improvement's quadruple aim.

Managing Acute Seizures: New Rescue Delivery Option and Resources to Assist School Nurses.

Approximately 470,000 children and adolescents in the United States have epilepsy, 30% of whom experience seizures despite antiseizure drug regimens. School nurses, teachers, caregivers, and parents play integral roles in implementing a care plan that avoids triggers, recognizes signs, and provides supportive care-ideally, guided by a patient-specific seizure action plan, which may include the use of rescue medication. Benzodiazepines are the mainstay of seizure rescue medication; for decades, rectally administered diazepam was the only approved rescue medication for seizure clusters outside the hospital setting. However, rectal administration has limitations that could delay treatment (e.g., social acceptability, removal of clothing, positioning). More recently, intranasal midazolam (for patients ≥12 years) and intranasal diazepam (for patients ≥6 years) were approved for this indication. Training and education regarding newer forms of rescue medication should improve confidence in the ability to treat seizures in school with the goal of increasing the safety of students with epilepsy.

Low-grade focal cortical dysplasia is associated with prenatal and perinatal brain injury.

PURPOSE: Prenatal and perinatal adverse events are reported to have a pathogenetic role in focal cortical dysplasia (FCD). However, no data are available regarding the prevalence and significance of this association. A cohort of children with significant prenatal and perinatal brain injury and histologically proven mild malformations of cortical development (mMCD) or FCD was analyzed. METHODS: We retrospectively evaluated a surgical series of 200 patients with histologically confirmed mMCD/FCD. Combined historical and radiologic inclusion criteria were used to identify patients with prenatal and perinatal risk factors. Electroclinical, imaging, neuropsychological, surgical, histopathologic, and seizure outcome data were reviewed. RESULTS: Prenatal and perinatal insults including severe prematurity, asphyxia, bleeding, hydrocephalus, and stroke occurred in 12.5% of children with mMCD/FCD (n = 25). Their epilepsy was characterized by early seizure onset, high seizure frequency, and absence of seizure control. Patients with significant prenatal and perinatal risk factors had more abnormal neurologic findings, lower intelligence quotient (IQ) scores, and slower background EEG activity than mMCD/FCD subjects without prenatal or perinatal brain injury. MRI evidence of cortical malformations was identified in 74% of patients. Most patients underwent large multilobar resections or hemispherectomies; 54% were seizure-free 2 years after surgery. Histologically "milder" forms of cortical malformations (mMCD and FCD type I) were observed most commonly in our series. CONCLUSIONS: Surgically remediable low-grade cortical malformations may occur in children with significant prenatally and perinatally acquired encephalopathies and play an important role in the pathogenesis of their epilepsy. Presurgical detection of dysplastic cortex has important practical consequences for surgical planning.

Counseling of parents of a child with uncontrollable seizures.

This review deals with the problem of counseling parents of children with intractable epilepsy. The previous topics address the complexity of the pathophysiology and the treatment options available both mainstream and alternative. However, knowing the reasons for intractability or the reasons for treatment failure may be insufficient to guide the health care professional in trying to help families deal with this problem on a day-to-day basis. There is no greater challenge for the epilepsy professional than caring for this group of patients. How do we help the parents of children we cannot help? Although we may not be able to eliminate seizures, we can be accessible and listen openly. We can try and help families develop strategies, skills, and resources that empower them to manage their situation more effectively.

Evaluating risk factors for violence at the inpatient unit level: combining young adult patients and those with mental retardation.

The current study demonstrates the use of patient case mix to evaluate the probability of aggression occurring on an inpatient psychiatric unit. The impact of combining young adult psychiatric patients with patients classified with mental retardation on the overall negative events and injuries on an inpatient psychiatric unit was evaluated. Results suggest when the combined number of young adults and patients classified with mental retardation exceeds 10 the unit is at high risk for aggressive behavior occurring. Recommendations for evaluating violence at a unit level using case mix are provided.

Surgery for epilepsy due to cortical malformations: ten-year follow-up.

Children with malformations of cortical development represent a significant proportion of pediatric epilepsy surgery candidates. From a cohort of 40 children operated on between 1980 and 1992 with malformation of cortical development, 38 were alive and had data 10 years after surgery. Age at surgery ranged from 6 months to 18 years (mean, 9.6 years). Thirty-six had partial seizures, and two had infantile spasms; 20 were nonlesional. Pathologic diagnoses were cortical dysplasia (n = 31) and developmental tumor (n = 7). At 10-year follow-up, 15 (40%) were seizure free, 10 (26%) had >90% seizure reduction, and 13 (34%) were improved or unchanged. Children seizure free at two-year follow-up were likely to remain seizure free. Ten-year seizure freedom was 72% in children with developmental tumors and 32% in the cortical dysplasia group. Complete resection was statistically significant for favorable outcome, and no patient with an incomplete resection was seizure free.

Validation of the quality of life in childhood epilepsy questionnaire in American epilepsy patients.

The aim of this study was to adapt the Australian Quality of Life in Childhood Epilepsy Questionnaire (QOLCE) and determine its psychometric properties in a North American population. Participants were North American families with children diagnosed with epilepsy. Parents were asked to complete the American QOLCE (USQOLCE) and the Child Health Questionnaire (CHQ). Seventy-one families completed the USQOLCE. The internal consistency reliability of the subscales was good. USQOLCE subscales correlated highly with theoretically similar subscales contained in the CHQ. Theoretically dissimilar subscales on the two instruments did not correlate as well. USQOLCE correlated significantly with a parental rating of seizure severity and an independent measure of degree of postoperative seizure control. This study demonstrated that the USQOLCE is suitable for a North American population with evidence of its reliability and validity including its sensitivity to seizure burden.
