Arquivos de Neuro-Psiquiatria, 2014
Myocardial scintigraphy with meta-iodo-benzyl-guanidine (123I cMIBG) has been studied in Parkinson's disease (PD), especially in Asian countries, but not in Latin America.

Miller Fisher syndrome with sinus arrest

Neurology International, 2017
Dysautonomia in Guillain-Barre syndrome (GBS) rarely causes serious cardiovascular complications, such as sinus arrest. Miller Fisher syndrome (MFS) is recognized as a variant of GBS.

Long COVID-19 and Postural Orthostatic Tachycardia Syndrome- Is Dysautonomia to Be Blamed?

Frontiers in Cardiovascular Medicine, 2022
While the increased arrhythmic tendency during acute COVID-19 infection is recognised, the long-term cardiac electrophysiological complications are less well known.

Comparative Analysis of Circulating Cytokines and Adrenergic Autoantibodies in Postural Orthostatic Tachycardia Syndrome, Postacute Sequelae of SARS‐CoV‐2, and Healthy Controls

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Postural orthostatic tachycardia syndrome (POTS) is increasingly recognized after SARS‐CoV‐2 infection. We compared autonomic phenotype, functional impact, and circulating immune markers in POTS, postacute sequelae of COVID‐19 (PASC), and ...

Prevalence and patterns of symptoms of dysautonomia in patients with long‐COVID syndrome: A cross‐sectional study

Annals of Clinical and Translational Neurology, 2022
Background The association between autonomic dysfunction and long‐COVID syndrome is established. However, the prevalence and patterns of symptoms of dysautonomia in long‐COVID syndrome in a large population are lacking.

Long COVID Patients with Orthostatic Intolerance Have Reduced Heart Rate Variability and Preserved Physiological Response to Active Standing

Biology
The aim of this study was to assess the heart rate variability (HRV) at rest and during active orthostatic challenge in long COVID patients with orthostatic intolerance symptoms (dizziness, pre-syncope, and syncope).

Novel brain SPECT imaging unravels abnormal cerebral perfusion in patients with postural orthostatic tachycardia syndrome and cognitive dysfunction

Scientific Reports
Cognitive dysfunction is frequently reported in individuals with postural orthostatic tachycardia syndrome (POTS), possibly resulting from reduced cerebral blood flow (CBF).

Relapses, Comorbidities, and Predictors of Outcome in Anti‐GABAA Receptor Encephalitis

Annals of Neurology, EarlyView.
Objectives To characterize the magnetic resonance imaging (MRI) lesion dynamics, comorbidities, predictors of relapse, and outcomes in anti‐γ‐aminobutyric acid type A receptor (GABAAR) encephalitis, and assess the utility of LIM‐domain‐only‐protein 5 (LMO5) antibodies as tumor markers.

Clinical Model‐Informed Precision Dosing Consult Service for Accelerating Personalized Medication in Pediatric Patients

Clinical Pharmacology &Therapeutics, EarlyView.
Traditional dosing strategies often rely on a “one‐size‐fits‐all” paradigm, assuming an “average” patient with typical demographic and pharmacological characteristics. In reality, this often overlooks existing between‐patient variability and can lead to suboptimal drug exposure or toxicity. This issue is especially pronounced in pediatric patients, who
