BACKGROUND: Long QT syndrome confers susceptibility to ventricular arrhythmia, predisposing to syncope, seizures, and sudden death. While rare globally, long QT syndrome is ≈15× more common in First Nations of Northern British Columbia largely because of a known mutation in KCNQ1. However, 2 large multigenerational families were affected, but negative for the known mutation. METHODS AND RESULTS: Long QT syndrome panel testing was carried out in the index case of each family, and clinical information was collected...

BACKGROUND: The Institute of Medicine, in a 2013 report, recommended that the Vaccine Safety Datalink (VSD) expand collaborations to include more diversity in the study population. Kaiser Permanente Colorado (KPCO), an established VSD site, partnered with Denver Health (DH), an integrated safety net healthcare system, to demonstrate the feasibility of integrating DH data within the VSD. Prior to incorporating the data, we examined the identification of specific vaccine associated adverse events (VAEs) in these two distinct healthcare systems...

BACKGROUND: Seizures result in a change in motor, sensory, and behavioral symptoms caused by abnormal neurologic electrical activity. The symptoms share similar presentations of several other conditions, leading to difficulties in diagnosis and frequent improper management. OBJECTIVE: This review evaluates adult patients with suspected seizure, signs and symptoms of seizure, mimics of seizure, and an approach to management of seizure mimics. DISCUSSION: A seizure is caused by abnormal neurologic electrical activity resulting in altered motor, sensory, and behavioral symptoms...

Catecholaminergic polymorphic ventricular tachycardia is a rare familial arrhythmogenic disease. It usually occurs in juvenile patients with a structurally normal heart and causes exercise-emotion triggered syncope and sudden cardiac death. The main gene associated with catecholaminergic polymorphic ventricular tachycardia is RyR2, encoding the cardiac ryanodine receptor protein which is involved in calcium homeostasis. After the identification of a 16 year-old man presenting with exercise-induced sudden cardiac death, clinically diagnosed as catecholaminergic polymorphic ventricular tachycardia, we collected the family information and performed a comprehensive genetic analysis using Next Generation Sequencing technology...

Ictal asystole (IA) is a rare phenomenon in patients with seizures with an incidence of 0.27-0.4% and has been proposed as a possible mechanism of sudden unexpected death in epilepsy patients (SUDEP). We present a case of a 53-year-old woman who initially presented with episodes of expressive aphasia and was treated with antiepileptic drugs (AEDs). While on therapy she experienced episodes of syncope. During her hospitalization for tapering of AEDs and 24-hour EEG monitoring, the patient developed a seizure followed by sinus bradycardia and an 18-second sinus pause, resulting in loss of consciousness and slowing of cerebral activity...

We present the case of a 66-year-old female with early onset deafness and seizures, who was diagnosed with epilepsy at the age of 2 years. She received antiepileptic drugs and was free of syncope episodes for 32 years. After a syncope at the age of 34, the ECG was characteristic of long-QT syndrome and was treated with antiarrhythmic drugs. Sequencing of the KCNQ1 gene identified two novel KCNQ1 variants interpreted to be pathogenic, and the patient was finally diagnosed with Jervell and Lange-Nielsen syndrome...

BACKGROUND: Spatiotemporal analysis of electroencephalography is commonly used for classification of events since it allows capturing dependencies across channels. The significant increase of feature vector dimensionality however introduce noise and thus it does not allow the classification models to be trained using a limited number of samples usually available in clinical studies. NEW METHOD: Thus, we investigate the classification of epileptic and non-epileptic events based on temporal and spectral analysis through the application of three different fusion schemes for the combination of information across channels...

Cardiovascular (CV) comorbidities are common in people with epilepsy. Several mechanisms explain why these conditions tend to co-exist including causal associations, shared risk factors and those resulting from epilepsy or its treatment. Various arrhythmias occurring during and after seizures have been described. Ictal asystole is the most common cause. The converse phenomenon, arrhythmias causing seizures, appears extremely rare and has only been reported in children following cardioinihibitory syncope. Arrhythmias in epilepsy may not only result from seizure activity but also from a shared genetic susceptibility...

A 22-year-old man was referred to us for syncope during a game of Captain's ball. There was no prodrome. His friends did not notice any ictal movements. He was otherwise well prior to passing out. He was not taking any medications or supplements. He was not usually physically active, but was otherwise well with no significant medical history. This is his first episode of syncope. There was no history of cardiac arrest or seizures. There is no family history of premature sudden cardiac death.Physical examination was normal...

BACKGROUND: Stroke is a leading cause of death and disability and most commonly presents with focal neurologic deficit within a specific vascular distribution. Several other conditions may present in a similar manner. OBJECTIVES: This review provides emergency providers with an understanding of stroke mimics, use of thrombolytics in these mimics, and keys to differentiate true stroke from mimic. DISCUSSION: Stroke has significant morbidity and mortality, and the American Heart Association emphasizes rapid recognition and aggressive treatment for patients with possible stroke-like symptoms, including thrombolytics...

Fahr's disease or Fahr's syndrome is a rare neurodegenerative disorder characterized by abnormal symmetrical calcifications of the basal ganglia, thalami, sub-cortical hemispheric white matter and deep cerebellar nuclei. It can be idiopathic or associated with an endocrinopathy, frequently with parathyroid disorder. Clinical spectrum of the disease is wide ranging from neurological features like seizure, syncope, stroke like events, extra-pyramidal symptoms often combined with frontal sub-cortical pattern of behavioural dysfunction and psychiatric symptoms such as psychosis, mood disorder and dementia...

In the investigation of psychogenic nonepileptic seizures (PNES), the main differential diagnoses are between convulsive PNES and tonic-clonic seizures, between swoon PNES and syncope, and between pseudoabsence PNES and absence seizures. For the best diagnostic certainty, events must be captured, ideally using video-electroencephalogram (EEG), including an electrocardiographic channel. The "video" part of video-EEG allows EEG changes (or lack of them) to be interpreted in the appropriate clinical context. When the diagnosis is based on less good data (e...

Psychogenic nonepileptic seizures (PNES) superficially resemble epileptic seizures or syncope and most patients with PNES are initially misdiagnosed as having one of the latter two types of transient loss of consciousness. However, evidence suggests that the subjective seizure experience of PNES and its main differential diagnoses are as different as the causes of these three disorders. In spite of this, and regardless of the fact that PNES are considered a mental disorder in the current nosologies, research has only given limited attention to the subjective symptomatology of PNES...

Stroke services have been centralised in several countries in recent years. Diagnosing acute stroke is challenging and a high proportion of patients admitted to stroke units are diagnosed as a non-stroke condition (stroke mimics). This study aims to describe the stroke mimic patient group, including their impact on stroke services. We analysed routine clinical data from 2,305 consecutive admissions to a stroke unit at St George's Hospital, London. Mimic groupings were derived from 335 individual codes into 17 groupings...

Medical emergencies that are life threatening can occur in dental practice. Complications may arise because of an underlying disease or a reaction to medication. Reactions to medications may be allergic and toxic. The most common reactions are toxic reactions to local anesthetics, whereas allergies occur mainly as a consequence of the application of antibiotics, usually penicillin. In response to stress, vasovagal syncope typically occurs. Other causes may be related to an underlying disease-specific pathology (such as acute asthma attack, diabetic ketoacidosis, hypoglycemia, or seizures) or accidents (aspiration of a foreign body causing obstruction of the respiratory system)...

OBJECTIVE: Cardiorespiratory function alterations are commonly observed with epileptic seizures and may lead to syncope and sudden unexpected death in epilepsy (SUDEP). Although most previous research has focused on controlling heart rate (HR) and respiration, little is known about seizure-related regulation of systemic blood pressure (BP). Herein, we have investigated whether the periictal modulation of systemic BP and HR depends on seizure characteristics. METHODS: Systemic arterial BP, HR, and peripheral capillary oxygen saturation (SPO2 ) were continuously and noninvasively monitored using the ccNexfin device in those epilepsy patients undergoing video-electroencephalography (EEG) telemetry...
