Varicella infection-induced cases, once the most common single Acute cerebellar ataxia, acute cerebellitis, and opsoclonus-myoclonus syndrome. J Child Department With Acute Ataxia in the Post-Varicella Vaccine Era. Acute post-infectious cerebellar ataxia is the most common cause of About 20 % of cases have been linked to varicella (chicken pox), but it. Post-viral cerebellar ataxia also known as acute cerebellitis and acute cerebellar ataxia (ACA) Viral infections that may cause it include the following: chickenpox, Coxsackie disease (viral infection also called hand-foot-and-mouth disease).

The nerve conduction velocity NCV studies of both lower limbs showed delayed F-response with ill-persistent F-waves.

Acute cerebellar ataxia in childhood: In fact, the onset of ataxia following the appearance of a typical chickenpox rash requires no further diagnostic testing. Median follow-up time was 1 year. Articles lacking in-text citations from August All articles lacking in-text citations All articles with unsourced statements Articles with unsourced statements from August Articles with unsourced statements from September Articles with incomplete citations from August All articles with incomplete citations.

Support Center Support Center. In literature we found other reports which describe infection of VZV and neurological complication encephalitis, meningitis, cerebellitis, poliradiculopaty, transverse myelitis in adults and children [ 343031 ].

We reviewed charts of children with varicella hospitalized during the study period. J Neurosurg ; 1 Suppl 57— Neurological complications following primary chicken varicla infection are extremely rare 0. Computed tomography CT scan of brain and routine X-rays of the vertebra were normal. In fact, CT is of limited value given the difficulty of imaging the posterior fossa with this modality. Chi-square test or Fisher exact test were performed to assess association between categorical variables, while Mann-Whitney test were used for quantitative variables.


Indeed, none of the patients included had been vaccinated against varicella. The general examination otherwise including vitals was found to be within normal limits. The cause has been postulated as either direct viral invasion[ 5 ] or through an immune-mediated allergic mechanism.

Controlled trial of acyclovir for chickenpox evaluating time of initiation and duration of therapy and viral resistance. Chicken pox is a viral infection affecting mainly children and presents with exanthematous rash with fever.

Post chicken pox neurological sequelae: Three distinct presentations

These were the varivela two children who underwent a computed tomography CT scan with pathological findings and the only two children with neurological sequelae.

We used the Chi square test or the Fisher exact test for comparing proportions. Finally, as well as in our case-series, other authors generally did not refer invalidating problems at the follow-up [ 114 ]. Assessment focuses on excluding serious and treatable causes including CNS infection and mass lesions.

A more complicated test that is performed for research analysis of the disease is to isolate viruses from the CSF cerebrospinal fluid. The onset is acute, typically within 1 week of development of rash.

Autoantibodies in postinfectious acute cerebellar ataxia. ATM is a condition of sudden weakness of lower extremities with sensory involvement caused due to inflammation of the spinal cord. We scanned the references of all included articles for additional studies. There was uncontrollable shaking of hands whenever he attempted any movement.

He had dysarthia and poorly localized low back pain. Hospitalization rates for complicated and uncomplicated chickenpox in a poorly vaccined pediatric population. After a long hospitalization median of 11 daysall but one children were dismissed without invalidating sequelae. Real time PCR for varicella zoster virus was positive in all cerebrospinal fluid samples.

Post chicken pox neurological sequelae: Three distinct presentations

Steppage gait Antalgic gait. A cute childhood ataxia: The infection is usually self-limiting and resolves without sequelae. Neurological complications were identified in 92 out variecla patients In each case, the following data were collected: Cerebellar leptomeningeal enhancement; CT: CSF electrophoresis was not done.

Z Gesamate Neurol Psychiatr. Controlled trial of acyclovir for chickenpox evaluating time of initiation and duration of therapy and viral resistance. The cause of the disease was unknown until when Weiss and Guberman proposed that ACA could be due to direct invasion of the central nervous vwricela by infectious agents. Critical review of neurological complications of certain fevers. Brain imaging is not cerebeltiis for most cases of AC.

Footnotes Source of Support: In a few cases, irritability 8. Based on these findings, a diagnosis of meningitis, cerebellitis and bilateral radiculopathy caused by varicella infection was established. Demographic, clinical, laboratory and microbiological data, neurologic investigations, radiologic studies and treatments, outcome and instrumental findings at follow-up were registered.

Acute cerebellitis in varicella: a ten year case series and systematic review of the literature

The neurological examination showed normal higher functions, no signs of meningeal irritation, normal cranial nerves and no evidences of cerebellar involvement. Children hospitalized for varicella: In cases where an underlying cause is identified, your doctor will treat the underlying cause. Varicella- zoster virus infection Pots Principles of internal medicine. If the acute cerebellar ataxia is due to bleeding, surgery may be needed.
