A CASE OF WEST NILE ENCEPHALITIS FROM CENTRAL INDIA

There have been isolated cases of West Nile virus (WNV) infection from Kerala,Gujarat and Maharashtra but it has never been previously reported in Central India.We report a rare case of West Nile encephalitis from central India in a middle aged female presented with fever, headache, vomiting, pain abdomen, and followed by acute onset flaccid paralysis (AFP).To the best of our knowledge it is first report of West Nile Virus from Central India

A Case of West Nile Encephalitis That Develops into a Disease of Deep White Matter on MRI over a Two-Week Span.

We present a case of serologically proved West Nile encephalitis. This patient had a normal MRI on admission. Given that the patient's clinical picture had worsened during her admission, a repeat MRI was performed, which demonstrated diffuse disease in the deep white matter of the brain. This is a case of West Nice encephalitis presenting as a disease of deep white matter that developed over a two-week span.

West Nile Encephalitis in a previously healthy child: Evaluation for CCR5 Chemokine receptor mutation

Neuroinvasive disease seldom follows infection with West Nile virus, but is particularly rare in children. Most reported cases of West Nile virus encephalitis have occurred in older adults or the immunocompromised. Although individuals who are homozygous for a 32 base pair deletion in the chemokine receptor CCR5 have been shown to be resistant to infection with HIV-1, they have been reported to have in increased risk of developing severe disease following West Nile virus infection. Analysis of the presence of the CCR5 deletion has not been previously examined in children with West Nile neuroinvasive disease. We present a case of West Nile encephalitis in a previously healthy young child whom we evaluated for the presence of the CCR5Δ32 mutation.

Three Cases of West Nile Encephalitis over an Eight-Day Period at a Downtown Los Angeles Community Hospital.

Since its introduction in New York City in 1999, the virus has spread throughout the entire North American continent and continues to spread into Central and Latin America. Our report discusses the signs and symptoms, diagnostics, and treatment of West Nile disease. It is important to recognize the disease quickly and initiate appropriate treatment. We present three cases of West Nile encephalitis at White Memorial Medical Center in East Los Angeles that occurred over the span of eight days. All three patients live within four to six miles from the hospital and do not live or work in an environment favorable to mosquitoes including shallow bodies of standing water, abandoned tires, or mud ruts. All the patients were Hispanic. Physicians and other health care providers should consider West Nile infection in the differential diagnosis of causes of aseptic meningitis and encephalitis, obtain appropriate laboratory studies, and promptly report cases to public health authorities. State governments should establish abatement programs that will eliminate sources that allow for mosquito reproduction and harboring. The public needs to be given resources that educate them on what entails the disease caused by the West Nile virus, what the symptoms are, and, most importantly, what they can do to prevent themselves from becoming infected.

The First Reported Case of West Nile Encephalitis in Korea

West Nile encephalitis was first identified in 1937, but until now, it was never diagnosed in Korea. A 58-yr-old Korean man was admitted with headache and cognitive dysfunction. The patient had been on a business trip in Guinea. Cerebrospinal fluid (CSF) showed pleocytosis. The patient complained of both leg weakness,and arachnoiditis and myelitis were observed on lumbar magnetic resonance imaging (MRI). A specific neutralizing antibody for West Nile virus was positive in serum. After a treatment with interferon-α 3mu, follow up CSF findings recovered completely after 3 months later. The first case of West Nile encephalitis in Korea was imported from Guinea, and was cured successfully.

Listeria monocytogenes encephalitis mimicking west nile encephalitis

We present a case of a 50-year-old man who presented to Winthrop-University Hospital in the midst of the 2002 West Nile encephalitis (WNE) outbreak with the cardinal clinical findings of WNE, ie, fever, encephalopathy, weakness, and muscle tremors. During the summer of 2002, several cases of aseptic meningitis/viral encephalitis were admitted to our emergency room weekly. In addition, cases of WNE were being admitted at the same time. During this period we had 3 cases of WNE. Our patient presented with the clinical findings of WNE. However, laboratory and radiologic findings suggested the possibility of Listeria monocytogenes encephalitis. The cerebrospinal fluid findings included red blood cells, which, in the absence of a traumatic tap or HSV encephalitis, argue against the diagnosis of WNE but are consistent with L. monocytogenes encephalitis. Computed tomography scan showed communicating hydrocephalus, which also suggests the possibility of L. monocytogenes and argued against the diagnosis of WNE. Clinicians should be vigilant for the mimics of WNE in geographical areas where WNE outbreaks are occurring.
