1/9. Acute cerebellar ataxia associated with chickenpox.A case of a child with acute cerebellar ataxia associated with chickenpox virus infection is described. Acute cerebellar ataxia associated with chickenpox is a well-recognised complication and the pertinent features of this condition are discussed.- - - - - - - - - - ranking = 1keywords = chickenpox (Clic here for more details about this article) |
2/9. Pre-eruptive varicella encephalitis and cerebellar ataxia.Varicella-related neurologic symptoms usually appear during or following the exanthem. Pre-eruptive neurologic manifestations are extremely rare. We report a 6-year-old boy who developed encephalitis, characterized by drowsiness and left-sided hyperactive deep tendon reflexes and cerebellar ataxia, both of which antedated the exanthem by 16 days. The diagnostic and public health implications are discussed.- - - - - - - - - - ranking = 0.080966045379802keywords = varicella (Clic here for more details about this article) |
3/9. Varicella and acute cerebellar ataxia.In two cases of varicella-associated cerebellar ataxia, varicella-zoster antigens in CSF cells were shown by an indirect immunofluorescent technique. Direct viral invasion in CNS disease complicating varicella plays an important part in pathogenesis and rules out a single immune-mediated mechanism.- - - - - - - - - - ranking = 0.060724534034851keywords = varicella (Clic here for more details about this article) |
4/9. Recurrent and pre-eruptive acute cerebellar ataxia: a rare case of varicella.This is a report of an unusual case of acute cerebellar ataxia in which the ataxia recurred after a 6 week interval and the second episode of ataxia antedated the varicella exanthem by 19 days, suggesting the direct invasion of the central nervous system by the varicella virus.- - - - - - - - - - ranking = 0.1214490680697keywords = varicella (Clic here for more details about this article) |
5/9. Pre-eruptive varicella cerebellitis confirmed by PCR.The diagnosis of pre-eruptive varicella cerebellitis is usually based on a history of exposure and thus depends on a subjective clinical assessment. The confirmation of the diagnosis has traditionally depended on the development of skin manifestations of varicella and on varicella-zoster antibody seroconversion. Confirming the diagnosis of pre-eruptive cerebellar ataxia or encephalitis early in the course of a viral infection may save the patient unnecessary tests, procedures, or attempts at therapeutic intervention. A patient is reported in whom, after clinically suspecting a diagnosis of pre-eruptive varicella cerebellitis, the diagnosis was confirmed by performing polymerase chain reaction analysis of varicella-zoster virus dna in peripheral blood leukocytes and cerebrospinal fluid. The patient developed skin manifestations of varicella 5 days after the onset of neurologic symptoms and 15 days after known exposure. In some patients with preeruptive varicella cerebellitis, polymerase chain reaction may be extremely useful for rapid confirmation of the diagnosis.- - - - - - - - - - ranking = 0.22265662479445keywords = varicella (Clic here for more details about this article) |
6/9. Pre-eruptive neurologic manifestations associated with multiple cerebral infarcts in varicella.A boy, 4 years, 9 months of age, presented with acute hemiplegia, lethargy, ataxia, and dysarthria 24 hours prior to the eruption of typical varicella exanthem. magnetic resonance imaging findings were typical of multiple cerebral ischemic infarcts. It is suggested that during the period of secondary viremia varicella zoster virus invaded the cerebral blood vessels causing vasculopathy and cerebrovascular infarcts.- - - - - - - - - - ranking = 0.1214490680697keywords = varicella (Clic here for more details about this article) |
7/9. Hemorrhagic varicella: a case report and review of the complications of varicella in children.The case of a previously healthy child who developed progressive systemic varicella with purpura is reported. The clinical course of this patient is outlined, and the range of potential complications of chickenpox in children is reviewed. Familiarity with the usual uncomplicated natural history of primary varicella infection should alert the clinician to signs and symptoms that signal significant systemic involvement.- - - - - - - - - - ranking = 0.36908178011617keywords = chickenpox, varicella (Clic here for more details about this article) |
8/9. Acute cerebellar ataxia with abnormal MRI lesions after varicella vaccination.A 2-year-old boy, with the primary difficulties of nausea and vomiting, developed a staggering gait and dysarthria 10 days after varicella vaccination. magnetic resonance imaging demonstrated multiple areas of high signal intensity in the white matter of the cerebellum, predominantly in the parieto-occipital white matter and both globus pallidi. He did not present any signs of myelitis or encephalitis and thus his cerebellar dysfunction was diagnosed as acute cerebellar ataxia, which is, generally speaking, not an etiologic entity but a clinical syndrome. magnetic resonance imaging may reveal a variety of abnormalities of the central nervous system in acute cerebellar ataxia.- - - - - - - - - - ranking = 0.10120755672475keywords = varicella (Clic here for more details about this article) |
9/9. Complicated varicella zoster infection in 8 paediatric patients and review of literature.BACKGROUND: This is a study of complicated varicella zoster infection in paediatric patients. AIM: To find out the number of patients with such complications, the types of complications and their outcome. METHOD: This involved a retrospective review of the case records of 8 patients who presented to our unit over a 12-month period (Jan-Dec 96). All patients were previously well without any underlying immunodeficiency. Varicella zoster (VZ) infection was confirmed by VZ immunofluorescence from vesicular fluid. RESULTS: CMS complications accounted for 6 of the 8 cases. Of these, 3 presented with encephalitis, 2 with cerebella ataxia and 1 with aseptic meningitis and cerebella ataxia. Of the non-CNS cases, 1 presented with glomerulonephritis with superimposed staphylococcus infection of skin ulcers; the other had disseminated VZ infection with haemorrhagic vesicles, hepatitis, ileus with mesenteric adenitis and disseminated intravascular coagulation. OUTCOME: The patient with disseminated VZ infection and multiple organ involvement died 5 days after a stormy course. One patient with encephalitis who had status epilepticus for 2 hours had behavioural problems and poor memory. The remaining 6 patients had no sequelae. CONCLUSION: VZ infection usually a minor illness, can result in serious life-threatening complications in previously healthy patients.- - - - - - - - - - ranking = 0.10120755672475keywords = varicella (Clic here for more details about this article) |
