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...

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:
