Paediatric new-onset seizure clinic in Australia: Experience and lessons learnt

The international league against epilepsy primary healthcare educational curriculum: Assessment of educational needs

OBJECTIVE

To assess the need for an epilepsy educational curriculum for primary healthcare providers formulated by the International League Against Epilepsy (ILAE) and the importance attributed to its competencies by epilepsy specialists and primary care providers and across country-income settings.

METHODS

The ILAE primary care epilepsy curriculum was translated to five languages. A structured questionnaire assessing the importance of its 26 curricular competencies was posted online and publicized widely to an international community. Respondents included epilepsy specialists, primary care providers, and others from three World Bank country-income categories. Responses from different groups were compared with univariate and ordinal logistic regression analyses.

RESULTS

Of 785 respondents, 60% noted that a primary care epilepsy curriculum did not exist or they were unaware of one in their country. Median ranks of importance for all competencies were high (very important to extremely important) in the entire sample and across different groups. Fewer primary care providers than specialists rated the following competencies as extremely important: definition of epilepsy (p = .03), recognition of seizure mimics (p = .02), interpretation of test results for epilepsy care (p = .001), identification of drug-resistant epilepsy (0.005) and management of psychiatric comorbidities (0.05). Likewise, fewer respondents from LMICs in comparison to UMICs rated 15 competencies as extremely important.

SIGNIFICANCE

The survey underscores the unmet need for an epilepsy curriculum in primary care and the relevance of its competencies across different vocational and socioeconomic settings. Differences across vocational and country income groups indicate that educational packages should be developed and adapted to needs in different settings.

Clinical characteristics and diagnoses of 1213 children referred to a first seizure clinic

OBJECTIVE

New-onset seizure-like events (SLEs) are common in children, but differentiating between epilepsy and its mimics is challenging. This study provides an overview of the clinical characteristics, diagnoses, and corresponding etiologies of children evaluated at a first seizure clinic (FSC), which will be helpful for all physicians involved in the care of children with SLEs.

METHODS

We included 1213 children who were referred to the FSC of a Dutch tertiary children's hospital over a 13-year period and described their clinical characteristics, first routine EEG recording results, and the distribution and specification of their eventual epilepsy and non-epilepsy diagnoses. The time interval to correct diagnosis and the diagnostic accuracy of the FSC were evaluated.

RESULTS

"Epilepsy" was eventually diagnosed in 407 children (33.5%), "no epilepsy" in 737 (60.8%), and the diagnosis remained "unclear" in 69 (5.7%). Epileptiform abnormalities were seen in 60.9% of the EEG recordings in the "epilepsy" group, and in 5.7% and 11.6% of the "no epilepsy" and "unclear" group, respectively. Of all children with final "epilepsy" and "no epilepsy" diagnoses, 68.6% already received their diagnosis at FSC consultation, and 2.9% of the children were initially misdiagnosed. The mean time to final diagnosis was 2.0 months, and 91.3% of all children received their final diagnosis within 12 months after the FSC consultation.

SIGNIFICANCE

We describe the largest pediatric FSC cohort to date, which can serve as a clinical frame of reference. The experience and expertise built at FSCs will improve and accelerate diagnosis in children with SLEs.

PLAIN LANGUAGE SUMMARY

Many children experience events that resemble but not necessarily are seizures. Distinguishing between seizures and seizure mimics is important but challenging. Specialized first-seizure clinics can help with this. Here, we report data from 1213 children who were referred to the first seizure clinic of a Dutch children's hospital. One-third of them were diagnosed with epilepsy. In 68.8% of all children-with and without epilepsy-the diagnosis was made during the first consultation. Less than 3% were misdiagnosed. This study may help physicians in what to expect regarding the diagnoses in children who present with events that resemble seizures.

Pediatric syncope: pearls and pitfalls in history taking

Syncope is a heterogeneous syndrome with complex underlying mechanisms, hence, the spectrum of patients presenting with syncope is broad. The diagnosis of syncope begins with history taking, and an accurate diagnosis can be established through correct history taking and interpretation. Building and interpreting patient history are the main factors that cause a diagnostic yield gap between experts and nonexperts. The most frequent source of error is a clinician's misconception rather than an inaccurate account of patient symptoms. Clinicians can have several diagnostic pitfalls while evaluating patient history, which can be avoided by in-depth understanding of the link between syncope pathophysiology and clinical clues. Furthermore, clinicians need to understand the clinical features of diseases that require differentiation from syncope, such as seizures. The use of confusing terms is one of the barriers that prevents accurate diagnosis and communication between doctors and patients. In this review, we address the terms of syncope and its essential history-taking components in connection with the mechanism of syncope.

Diagnostic Delay in Epilepsy: the Scope of the Problem

PURPOSE OF REVIEW

Diagnostic delay is an increasingly recognized issue in epilepsy. At the same time, there is a clear disparity between public awareness of epilepsy and that of other public health issues. A contributing factor for this seems to be a lack of studies testing interventions designed to improve seizure recognition. In this review, we summarize the main findings from recent studies investigating diagnostic delay in epilepsy, highlighting causes, consequences, and potential interventions in future research that may improve quality of care in this population.

RECENT FINDINGS

Building on prior evidence, diagnostic delay in patients with new-onset focal epilepsy has been identified as an important problem for patients with epilepsy. Such delay in diagnosis can lead to delayed treatment and potentially preventable morbidity and mortality including motor vehicle accidents. Nonmotor seizure semiology appears to be a major contributor for delay; such seizures are largely unrecognized when patients present to emergency departments for care. Improving recognition and diagnosis of recurrent nonmotor seizures in emergency departments represents a significant opportunity for improving time to diagnosis, particularly when patients present following a first lifetime motor seizure and meet diagnostic criteria for epilepsy. Diagnostic delay in epilepsy is a significant public health issue and recent studies have highlighted potential areas for intervention.

Evaluation of pediatric patients in new-onset seizure clinic (NOSc)

AIM

We evaluated the clinical and demographic features of children presenting with unprovoked seizures at a regional new-onset seizure clinic (NOSc).

METHODS

We retrospectively reviewed charts of 492 consecutive patients evaluated in the NOSc at the Childrne's Healthcare of Atlanta RESULTS: Nonepileptic events (NEE) were diagnosed in 102 (24%) and epileptic seizures in the remaining 326 (76%). Patients with NEE were younger than patients with epileptic seizure (5.0 vs. 7.4 years). Except for headache which occurred more frequently in NEE (14% vs. 6%), frequencies of comorbidities were similar in groups with NEE and epileptic seizure. Electroencephalogram (EEG) was performed in 98%, and finding was abnormal in 51%. Brain magnetic resonance imaging (MRI) was performed in 55%, and finding was abnormal in 15%. An electroclinical epilepsy syndrome was diagnosed in 42%. Antiseizure medication was started in 25% with first seizure and in 77% with recurrent seizures.

INTERPRETATION

For children with newly-presenting seizures, a regional NOSc provided efficient, timely diagnosis and appropriate evaluations and treatment. Timely recognition of NEE resulted in fewer unnecessary evaluations and treatment for a quarter of referred patients whereas identification of the specific types of seizures and epilepsy allowed appropriate use, including deferral, of neuroimaging and guided treatment selection.
