Common Features Between Stroke Following Varicella in Children and Stroke Following Herpes Zoster in Adults : Varicella-Zoster Virus in Trigeminal Ganglion
Curr Top Microbiol Immunol. 2021 Jul 6. doi: 10.1007/82_2021_236. Online ahead of print.ABSTRACTThe cerebral arteries are innervated by afferent fibers from the trigeminal ganglia. Varicella-zoster virus (VZV) frequently resides in the trigeminal ganglion. Reports of arterial ischemic stroke due to VZV cerebral vasculopathy in adults after herpes zoster have been described for decades. Reports of arterial ischemic stroke due to post-varicella cerebral arteriopathy in children have also been described for decades. One rationale for this review has been post-licensure studies that have shown an apparent protective effect fro...

An Erratic Exanthem: Postvaricella Guillain-Barre Syndrome With Facial Diplegia
Varicella zoster (Chickenpox) usually occurs in childhood due to infection with varicella zoster virus. It manifests as an acute febrile exanthem which is usually self-limiting. Varicella zoster virus infection, in most cases, provides lifelong immunity to an individual after primary infection. In adults, primary varicella is uncommon, and most cases occur as a result of reactivation of the dormant virus. Subsequently, in adults, varicella infection can behave erratically to present with various unusual systemic and neurological complications, which are again uncommonly seen after primary varicella. The most common neurolo...

An unusual neurological syndrome in a haemodialysis patient
Nisha Jose, V Jayaprakash, A Deiva, M JayakumarIndian Journal of Nephrology 2021 31(3):293-295 Advanced age and immunosuppressed states allow for complications of herpes zoster such as encephalitis. In this case report, we describe a patient with encephalopathy two days after initiation of antiviral therapy. After the necessary imaging and cerebrospinal fluid (CSF) analysis, it became evident that the neurological syndrome was due to acyclovir. Despite currently practised renal dose modification, the patient developed acyclovir-induced neurotoxicity and required intensification of his dialysis schedule to eliminate the dr...

Clinical and radiological aspects of bilateral temporal abnormalities: pictorial essay
Abstract The temporal lobes are vulnerable to several diseases, including infectious, immune-mediated, degenerative, vascular, metabolic, and neoplastic processes. Therefore, lesions in the temporal lobes can pose a diagnostic challenge for the radiologist. The temporal lobes are connected by structures such as the anterior commissure, corpus callosum, and hippocampal commissure. That interconnectedness favors bilateral involvement in various clinical contexts. This pictorial essay is based on a retrospective analysis of case files from a tertiary university hospital and aims to illustrate some of the conditions that simul...

Concurrent maxillary herpes zoster, meningitis, focal cerebral arteriopathy, and ischemic stroke: A case report
Secondary headache, fever, and upper motor neuron signs following facial herpes zoster during childhood should alert clinicians to the possibility of central nervous system complications of varicella ‐zoster virus infection. AbstractSecondary headache, fever, and upper motor neuron signs following facial herpes zoster during childhood should alert clinicians to the possibility of central nervous system complications of varicella ‐zoster virus infection.

Herpes simplex virus 2 vasculitis as cause of ischemic stroke in a young immunocompromised patient
We report a case of a young woman with a left middle cerebral artery (MCA) ischemic stroke. The patient had history of HIV-1 infection, with periods of therapeutic non-compliance. Initial computed tomography (CT) imaging studies showed stenosis of the M1 segment of the left MCA, and magnetic resonance imaging (MRI) confirmed infarction of the MCA territory. Serial transcranial Doppler ultrasound revealed progressive occlusion of the MCA and stenosis of the left anterior cerebral artery. Systemic investigation for other causes of stroke was normal. Lumbar puncture revealed a mildly inflammatory cerebrospinal fluid, and HSV-...

Intracranial calcifications in childhood: Part 2
This article is the second of a two-part series on intracranial calcification in childhood. In Part 1, the authors discussed the main differences between physiological and pathological intracranial calcification. They also outlined histological intracranial calcification characteristics and how these can be detected across different neuroimaging modalities. Part 1 emphasized the importance of age at presentation and intracranial calcification location and proposed a comprehensive neuroimaging approach toward the differential diagnosis of the causes of intracranial calcification. Pathological intracranial calcification can ...
