Parvovirus B19 Infection in Children With Arterial Ischemic Stroke Brief Report
Conclusions—Using MassTag–polymerase chain reaction, we detected parvovirus B19—a virus known to infect erythrocytes and endothelial cells—in some cases of childhood arterial ischemic stroke. This approach can generate new, testable hypotheses about childhood stroke pathogenesis.

What Causes Ataxia?
Discussion Coordination and balance problems are caused by various problems affecting the central and peripheral nervous system. Normal development of a child or weakness of a child are commonly mistaken for true ataxia. Ataxia specifically refers to “…impairment of the coordination of movement without loss of muscle strength.” If it is purely due to abnormalities of the cerebellum then there should be no changes in mental status, sensation or weakness. Sometimes it is difficult to determine if there are abnormalities in other areas. For example, Guillian-Barre often presents with difficulty or clumsy wal...

An unusual cause of cerebellar ataxia in an immunocompromised elderly patient
Conclusions: PVB19 CNS infection should be in the differential as a cause of cerebellar ataxia in immunocompromised patients. Recognition is critical to early institution of appropriate therapy. Our patient showed considerable improvement in ataxia after IVIG therapy.Highlights:

In the heart of MELAS syndrome
With interest we read the article by Youssef et al. about a 25year old male with mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS) syndrome who experienced an acute deterioration of left ventricular function being attributed to myocarditis from a presumed parvovirus B19 infection [1]. We have the following comments and concerns.

Parvovirus B19 infection associated with hemolytic anemia and cranial polyneuropathy
AbstractParvovirus B19 (PB19) is a common, widespread, small, single-stranded DNA virus which has been linked with a broad spectrum of clinical illnesses, including a variety of neurological complications such as encephalitis, meningitis, myelitis, stroke, cerebellar ataxia, and neuropathy. The authors describe a case of PB19 infection associated with hemolytic anemia and cranial polyneuropathy involving the second and third cranial nerves in a 23-year-old immunocompetent woman. The diagnosis of acute PB19 infection was established with detection of positive DNA and anti-PB19 IgM antibodies in blood samples. Antigangliosid...

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 ...

Lack of Association between Seropositivity of Vasculopathy-Related Viruses and Moyamoya Disease
CONCLUSIONS: Our cross-sectional study suggest that the investigated 11 viruses including HHV6 are unlikely to have an impact on MMD development.PMID:35500358 | DOI:10.1016/j.jstrokecerebrovasdis.2022.106509
