We used a remotely monitored non-contact biosensor (SleepMinder™) to measure breathing during sleep (SDB) in a prospective study of 91 patients with stable class II to IV heart failure (HF). The device algorithm measures a surrogate of the traditional apnoea/hypopnoea index (AHI) measured in polysomnographic sleep studies. Data was transmitted daily to a central monitoring centre and analysed in consecutive 2-week blocks. A total of 37 465 nights over 3-24 months was analysed. An AHI of >15/h was considered clinically significant...

OBJECTIVE: Psychogenic nonepileptic seizures (PNES) are abrupt, paroxysmal changes in behavior or consciousness that may phenomenologically resemble epileptic seizures. Given the known association between anxiety and PNES, we hypothesized that in these subjects there may be evidence that the nervous system is hypersensitive to external stimuli. We aimed to test our hypothesis by means of the auditory startle reaction (ASR). By investigating ASR, we also had the opportunity to test presence of orienting reaction, which is generally defined as the second phase of response after the auditory stimulus, with longer latency...

BACKGROUND: Because of its multifaceted nature, dizziness is difficult for clinicians to diagnose and manage independently. Current treatment trends suggest that patients are often referred to the otolaryngologist for intervention despite having a nonotologic disorder. Additionally, many individuals with atypical presentations are often misdiagnosed and spend a significant amount of time waiting for consultation by the otolaryngologist. Few studies have alluded that implementation of an interprofessional team approach in the diagnosis and management of the dizzy patient can improve clinical decision-making...

The objective of the present study was to elucidate the frequency of causes underlying the development of dizziness and vertigo in the patients seeking advice and care at an outpatient healthcare facility. A total of 590 patients with complaints of dizziness and vertigo were examined. It was found out that the peripheral disorders of the vestibular analyzer were the most frequent causes of dizziness and vertigo in the majority of the examined patients. These conditions were documented to occur in more than 65% of the patients...

Morag Griffin, Talha Munir
Paroxysmal nocturnal haemoglobinuria (PNH), an ultra-orphan disease with a prevalence of 15.9 per million in Europe, is a life-threatening disorder, characterized by haemolysis, bone marrow failure and thrombosis. Patients with PNH prior to the availability of eculizumab had a median survival of between 10 and 22 years, with thrombosis accounting for 22-67% of deaths. 29-44% of patients had at least one thrombosis. This paper provides a clinician's guide to the diagnosis, management and complications of PNH, with an emphasis on thrombosis...

BACKGROUND: Gain-of-function mutations in SCN9A gene that encodes the voltage-gated sodium channel NaV1.7 have been associated with a wide spectrum of painful syndromes in humans including inherited erythromelalgia, paroxysmal extreme pain disorder and small fibre neuropathy. These mutations change the biophysical properties of NaV1.7 channels leading to hyperexcitability of dorsal root ganglion nociceptors and pain symptoms. There is a need for better understanding of how gain-of-function mutations alter the atomic structure of Nav1...

BACKGROUND: Hashimoto's encephalitis (HE) is a rare neurological complication of Hashimoto's thyroiditis (HT), while limbic encephalitis (LE) is an autoimmune inflammatory disorder frequently associated with anti-neuronal antibodies. The glutamate receptor α-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid receptor (AMPAR) is important for synaptic transmission, memory, and learning. The etiology of HE remains unclear. We present a case of HE with antibodies to AMPAR2 both in the serum and cerebrospinal fluid...

Rationale: Familial sinus node and atrioventricular (AV) conduction dysfunction is a rare disorder that leads to paroxysmal dizziness, fatigue and syncope due to a temporarily or permanent reduced heart rate. To date, only a few genes for familial sinus and/or AV conduction dysfunction are known and the majority of cases remain etiologically unresolved. Objective: We aim to identify the disease gene in a large three-generation family (n=25) with autosomal dominant sinus node dysfunction (SND) and AV block (AVB) and to characterise the mutation-related pathomechanisms in familial SND+AVB...

Oculogyric crises are a rare movement disorder characterized by paroxysmal, conjugate, tonic, usually upwards, deviation of the eyes. Causes for oculogyric crises are limited and include complications of dopamine-receptor blocking medications and neurometabolic disorders affecting dopamine metabolism, suggesting that an underlying hypodopaminergic state is important to the pathogenesis. Mimickers of oculogyric crises exist, and we propose diagnostic criteria to distinguish true oculogyric crises. Recognition of oculogyric crises is important for the diagnosis and appropriate treatment of rare disorders, and an approach to investigations in oculogyric crises is proposed...

The complement system is an essential part of the innate immune system that requires careful regulation to ensure responses are appropriately directed against harmful pathogens, while preventing collateral damage to normal host cells and tissues. While deficiency in some components of the complement pathway is associated with increased susceptibility to certain infections, it has also become clear that inappropriate activation of complement is an important contributor to human disease. A number of hematologic disorders are driven by complement, and these disorders may be termed "complementopathies"...

Spinal cord injury is a clinical syndrome encountered frequently in trauma centers and is accompanied by both acute and chronic heart rhythm abnormalities. The injury is characterized by sympathetic nervous system impairment with preservation of parasympathetic output via the vagus nerve. Severe bradycardia in the form of life-threatening sinus arrest or complete heart block may be observed in the acute recovery phase. Therapy for arrhythmias in the acute phase includes atropine, intravenous chronotropes, methylxanthines for the prevention of episodic bradycardia, and pacemaker implantation in severe cases...

Cerebral venous thrombosis (CVT) has a broad spectrum of clinical presentation compared to arterial etiology. Seizure is one of the common symptoms and is more frequent than in other stroke types. Hence, transient neurological symptoms in CVT patients are usually due to epileptic seizures, while transient repetitive movement disorder is extremely rare except as a complication of epilepsy. We report a case of CVT in the superior sagittal sinus with a 1-year history of paroxysmal kinetic tremor without evident epilepsy...

Accumulating studies reported mutations in the gene encoding the proline-rich transmembrane protein 2 (PRRT2) to be causative for several paroxysmal neurological disorders, including paroxysmal kinesigenic dyskinesia (PKD), PKD combined with infantile seizures (ICCA), and benign familial infantile seizures (BFIS). However, the impact of PRRT2 in tumorigenesis is not known. Based on a large-scale data analysis, we found that PRRT2 was down-regulated in glioma tumor tissues compared with normal brain tissue. Dysregulation of PRRT2 was not induced by mutation, copy number variation and epigenetic modification, but modulated by microRNA-30a-5p...

Paroxysmal dyskinesias (PDs) are a group of hyperkinetic movement disorders characterised by circumscribed episodes of disturbed movement, superimposed on a background state in which such abnormality is absent. There is no loss of consciousness. Episodes can last seconds, minutes or hours, and the beginning and end of the movement disturbance are abrupt. Neurological examination is typically normal between episodes. PDs are associated with a broad spectrum of clinical presentations, encompassing various aetiologies...
