NMDAR‐antibody encephalitis: Seizure semiology and EEG findings

open access: yesEpileptic Disorders, EarlyView.
Abstract Background N‐methyl‐D‐aspartate receptor antibody encephalitis (NMDAR‐Ab‐E) is an autoantibody‐mediated disorder, characterized by acute development of neuropsychiatric symptoms, seizures, movement disorders, and autonomic instability. Objectives To describe acute seizure semiology and electroencephalogram (EEG) findings in patients with a ...

Postural Hyperventilation as a Cause of Postural Tachycardia Syndrome: Increased Systemic Vascular Resistance and Decreased Cardiac Output When Upright in All Postural Tachycardia Syndrome Variants

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2018
Background Postural tachycardia syndrome (POTS) is a heterogeneous condition. We stratified patients previously evaluated for POTS on the basis of supine resting cardiac output (CO) or with the complaint of platypnea or “shortness of breath” during ...

Timing of congruent and discordant interictal epileptiform EEG discharges in focal epilepsy

open access: yesEpileptic Disorders, EarlyView.
Abstract Objective Interictal epileptiform discharges (IEDs) can provide additional information for localizing the epileptogenic zone (EZ). However, due to the brevity of routine electroencephalography, IEDs are often not recorded and there is a lack of general recommendation regarding the recording duration Methods In our study, we analyzed the mean ...

Occipital irregular delta activity in focal epilepsy

open access: yesEpileptic Disorders, EarlyView.
Abstract Objective Nonspecific occipital irregular delta activity (OID) is a common finding in focal epilepsy (FE). However, the significance of OID and its relationship to the underlying etiology of FE remain largely unstudied. This study aimed to investigate the relationship between OID and the etiology of FE, as well as the relationship between OID ...

Effects of acute hypoventilation and hyperventilation on exhaled carbon monoxide measurement in healthy volunteers

open access: yesBMC Pulmonary Medicine, 2009
Background High levels of exhaled carbon monoxide (eCO) are a marker of airway or lung inflammation. We investigated whether hypo- or hyperventilation can affect measured values.

Hypocalcemia and hypokalemia due to hyperventilation syndrome in spinal anesthesia -A case report- [PDF]

open access: yesKorean Journal of Anesthesiology, 2011
Hyperventilation syndrome (HVS) often occurs under stressful conditions, and has been reported during or after anesthesia and operation. HVS, characterized by multiple somatic symptoms and electrolyte imbalances induced by inappropriate hyperventilation,

Hyperventilation and Cerebral Blood Flow

open access: yes, 1972
Hypocapnic-hyperventilation has a profound, but probably temporary, effect on CBF, producing approximately a 2% decline in CBF for each 1 torr decline in P co co2 .

Epilepsy with eyelid myoclonia beyond the classical phenotype: Longitudinal electroclinical observations in a pediatric cohort

open access: yesEpileptic Disorders, EarlyView.
Abstract Objective Epilepsy with eyelid myoclonia is a childhood‐onset generalized epilepsy syndrome with variable recognition of eyelid myoclonia, eye‐closure sensitivity, and photosensitivity during follow‐up. We aimed to characterize longitudinal clinical and electroencephalographic features in pediatric epilepsy with eyelid myoclonia, focusing on ...

Role of nitric oxide in hypoxia-induced hyperventilation and hypothermia: participation of the locus coeruleus

open access: yesBrazilian Journal of Medical and Biological Research, 1999
Hypoxia elicits hyperventilation and hypothermia, but the mechanisms involved are not well understood. The nitric oxide (NO) pathway is involved in hypoxia-induced hypothermia and hyperventilation, and works as a neuromodulator in the central nervous ...
