The aim of this review was to analyze the existing literature concerning the relationship between Hashimoto's thyroiditis (HT) and vestibular dysfunction. METHODS: We used electronic databases (PubMed, EMBASE, Cochrane Library) to search and collect all published articles about association between HT and vestibular disorders. RESULTS: Several observational and retrospective studies have postulated a relationship of thyroid autoimmunity and vestibular disorders. In most cases, an appropriate control group was lacking and the impact of thyroid functional status could not precisely be established...

Voltage-gated sodium channel (NaV) mutations cause genetic pain disorders that range from severe paroxysmal pain to a congenital inability to sense pain. Previous studies on NaV1.7 and NaV1.8 established clear relationships between perturbations in channel function and divergent clinical phenotypes. By contrast, studies of NaV1.9 mutations have not revealed a clear relationship of channel dysfunction with the associated and contrasting clinical phenotypes. Here, we have elucidated the functional consequences of a NaV1...

Raynaud's phenomenon (RP) is a vasospastic disorder characterized by recurrent self-limited episodes of skin pallor, cyanosis, and hyperemia caused by paroxysmal spasms in the small arteries of the fingers and toes and can occur in any age group. Hands, feet, nose, ears, and nipples can be affected. The diagnosis is made clinically, assessing varying degrees of ischemia in the involved areas of skin, but this transient ischemia may also herald the onset of connective tissue disease. Investigation is recommended when RP starts in childhood to exclude an underlying autoimmune condition and close follow-up for its development...

REVIEW
Francisco J Guerrero-Márquez, Eduardo Arana-Rueda, Alonso Pedrote
Idiopathic paroxysmal atrioventricular (AV) block poses a true diagnostic challenge. What is clear about this entity is the confusion about its definition and consequently about its etiology. According to certain sources, the diagnosis of this block requires the lack of a structural cardiac pathology that justifies the observed manifestations and an absence of electrocardiographic disorders prior to an episode. The clinical presentation of idiopathic paroxysmal AV block does not differ from that of another cardiogenic syncope or of a vasovagal syncope with a significant cardioinhibitory component...

Vertigo and dizziness are among the most common chief complaints in the emergency department. Etiologies can be categorized into three subgroups: neurootological (vestibular), medical (especially cardiovascular, metabolic), and psychiatric disorders. The diagnostic approach in the emergency department is based on a systematic analysis of case history (type, time course of symptoms, modulating factors, associated symptoms), clinical examination of the vestibular, ocular motor, and cerebellar systems (head impulse test, nystagmus, skew deviation, positioning maneuver, test of gait and stance), as well as a basal monitoring (vital signs, 12-lead ECG, blood tests)...

Balance is achieved and maintained by a balance system called a labyrinth that is composed of three semicircular canals and the otolith organs that sense linear gravity and acceleration. Within each semicircular canal, there is a gelatinous structure called the cupula, which is deformed under the influence of the surrounding endolymph. One of the balance disorders is benign paroxysmal positional vertigo, and one of the pathological conditions that have been identified as possible causes of this syndrome is canalithiasis-disturbance of the endolymph flow and cupular displacement caused by the free-moving otoconia particles within the lumen of the canal...

Dysregulation of the complement system is linked to the pathogenesis of a variety of hematological disorders. Eculizumab, an anti-complement C5 monoclonal antibody, is the current standard of care for paroxysmal nocturnal hemoglobinuria (PNH) and atypical hemolytic uremic syndrome (aHUS). However, because of high levels of C5 in plasma, eculizumab has to be administered biweekly by intravenous infusion. By applying recycling technology through pH-dependent binding to C5, we generated a novel humanized antibody against C5, SKY59, which has long-lasting neutralization of C5...

Paroxysmal tonic spasms [PTS] are common in patients with neuromyelitis optica spectrum disorder (NMOSD).1 2 In patients with demyelinating disease, PTS can significantly reduce the quality of life, limit activities of daily living and the rehabilitative process following an acute relapse 3. As in patients with multiple sclerosis (MS), paroxysmal tonic spasms in NMOSD usually respond well to treatment with carbamazepine.2 However, the optimal treatment in patients where carbamazepine is contraindicated or poorly tolerated is unclear...

Psychogenic nonepileptic seizures (PNES) are defined as paroxysmal episodes in which epileptic semiology features are manifested, without the characteristic concomitant electrical discharges seen in epileptic seizures. Although many studies have dealt with semiologic classification of PNES, most of the studies did not raise the question of consistency of PNES in the same patient. The aim of this study was to measure the degree of consistency of PNES among individual patients. We retrospectively reviewed medical records and video- EEG records of all adult patients who underwent monitoring in our center from August 1st 2013 to May 31st 2015...

INTRODUCTION: Paroxysmal nocturnal hemoglobinuria (PNH) is a rare disease and can present as a wide range of signs and symptoms. As such, the indication for diagnostic testing for PNH is not always straightforward. Therefore, we analyzed all first-time samples tested over a 56-month period to determine the clinical settings with a high probability of detecting a PNH clone. METHODS: We retrospectively analyzed 323 first-time PNH flow cytometry tests, including LDH, cytopenias, direct antiglobulin test (DAT), and clinical indication for testing as available at the time of testing...

Background Many patients with mid-face or lower face craniofacial pain are diagnosed, based on accompanying signs and symptoms and features other than location, as either atypical migraines or atypical TACs. Distinguishing features of headache disorders as a cause of facial pain include the temporal pattern of pain, associated symptoms including light and sound sensitivity and nausea, cranial autonomic symptoms, and the lack of local triggering among others. Results An intraoral neurovascular pain has been observed, and was termed neurovascular orofacial pain (NVOP)...

Secondary paroxysmal dyskinesias (SPDs) are short, episodic, and recurrent movement disorders, classically related to multiple sclerosis (MS). Carbamazepine is effective, but with risk of adverse reactions. We identified 7 patients with SPD among 457 MS patients (1.53%). SPD occurred in face ( n = 1), leg ( n = 2), or arm +leg ( n = 4) several times during the day. Magnetic resonance imaging (MRI) showed new or enhancing lesions in thalamus ( n = 1), mesencephalic tegmentum ( n = 1), and cerebellar peduncles ( n = 5)...
