Guillain-Barré syndrome after coronavirus disease 2019 vaccine: A temporal association.

Background: Guillain-Barré syndrome (GBS) is an acute monophasic immune-mediated polyradiculoneuropathy, preceded by gastrointestinal or respiratory infections in up to two-thirds of patients. On rare occasions, people develop GBS after vaccination, but no causal association has been proven. In the current coronavirus disease 2019 (COVID-19) pandemic, some cases have been reported associating COVID-19 vaccine with GBS.

Cutaneous adverse reactions associated with antiseizure medication: clinical characteristics and implications in epilepsy treatment.

Objective: To describe the clinical characteristics of cutaneous adverse reactions and cross-sensitivity induced by antiseizure medications and compare the pattern of use of antiseizure medications in patients with epilepsy according to skin rash history.

Methods: We analysed patients with a history of skin rash presenting for up to 12 weeks after initiating antiseizure medication. The history of skin rash was verified by medical charts, interviews, and identification of skin lesions by patients based on illustrative images.

Parakinesia brachialis oscitans during thrombolytic therapy.

The authors describe a case report of a patient with parakinesia brachialis oscitans, which occurred during thrombolytic therapy, in a patient with left-middle cerebral artery occlusion.

Dopamine transporter imaging in clinically unclear cases of parkinsonism and the importance of scans without evidence of dopaminergic deficit (SWEDDs).

Unlabelled: The clinical diagnosis of Parkinson's disease (PD) is susceptible to misdiagnosis, especially in the earlier stages of the disease. Recently, in vivo imaging techniques assessing the presynaptic dopamine transporter (DAT) have emerged as a useful tool in PD diagnosis, improving its accuracy.

Objective: It was to illustrate the clinical usefulness of a brain single-photon emission computed tomography (SPECT) DAT ligand, and highlight relevant aspects of scans without evidence of dopaminergic deficit (SWEDDs) in this context.

Neurological diagnoses in the emergency room: differences between younger and older patients.

Unlabelled: Neurological diseases are prevalent in the emergency room (ER). The aim of this study was to compare the neurological diagnoses between younger and older patients evaluated in the ER of a tertiary care hospital.

Method: Patients admitted to the ER who required neurological evaluation in the first 24 hours were separated into two groups based on age, ≤50 years old and >50 years old.
