Acute herpes zoster radiculopathy mimicking cervical radiculopathy after ChAdOx1 nCoV-19/AZD1222 vaccination.

This case report describes an 84-year-old man who presented with 3 weeks of gradually worsening right arm weakness associated with a painful vesicular rash across his arm. This occurred 3 days after his first dose of the ChAdOx1 nCoV-19/AZD1222 (University of Oxford, AstraZeneca and the Serum Institute of India) vaccine. The diagnosis was complicated by the presence of right C5-C6 foraminal stenosis compressing on the C6 nerve root sheath on non-contrast MRI, leading to an initial diagnosis of cervical radiculopathy.

Cerebral arterial and venous thrombosis due to COVID-19 vaccine-induced immune thrombotic thrombocytopenia.

Vaccine-induced immune thrombotic thrombocytopenia (VITT) rarely develops after many COVID-19 vaccines. A 51-year-old woman re-presented to hospital with a 4 day history of headache, vomiting, diarrhoea and left calf pain, 11 days after her first dose of ChAdOx1nCoV-19 (AstraZenica) vaccine. Her neurological examination was normal.

The extrapyramidal syndromes of chronic kidney disease and dialysis (EPS-CKDD): diagnostic criteria, risk factors and prognosis.

Background: Acute extrapyramidal movement disorders in dialysis patients are rare, inconsistently defined and have uncertain aetiology and prognosis.

Aim: Define diagnostic criteria, prognosis and risk factors.

Design And Methods: Retrospective case series review of 20 patients (14 female, mean age 62 years) receiving dialysis for a median of 15 (interquartile range 4-35) months who presented with acute parkinsonism (AP = 11) or chorea/athetosis (CA = 9).

Guillain-Barré syndrome and posterior reversible leukoencephalopathy syndrome: a rare association.

A 69-year-old woman presented with headaches and visual disturbance in the context of marked hypertension secondary to non-compliance with antihypertensive medications. She developed seizures and hyperreflexia, and MRI brain showed changes consistent with posterior reversible encephalopathy syndrome (PRES). She was treated with antihypertensives with the resolution of symptoms.

Fulminant Anti-GAD antibody encephalitis presenting with status epilepticus requiring aggressive immunosuppression.

Antibodies against glutamic acid decarboxylase (GAD) are reported in association with numerous neurological conditions including temporal lobe epilepsy and limbic encephalitis. We report a case of Anti-GAD-Antibody associated encephalitis presenting with epilepsia partialis continua (EPC) progressing to a fulminant encephalopathy preferentially affecting the frontal lobes associated with coma and refractory status epilepticus. The abnormalities identified on MRI included marked bilateral frontal lobe involvement which has not been reported in other auto-immune encephalitides and may be specific for Anti-GAD-Antibody associated encephalitis.
