Researchers Urge Awareness of West Nile Symptoms

23.07.2004


Since West Nile virus is expected to be prominent again this summer – especially on the West Coast – University of Toronto researchers are urging physicians to be on the lookout for its most common manifestations.

A U of T study, published in the May issue of the quarterly Canadian Journal of Neuroscience, found that among hospitalized patients in Toronto with West Nile virus (WNV), encephalitis was the most common neurological manifestation. More surprisingly, encephalitis was an apparent risk factor for neuromuscular complications; it’s very rare for this brain infection to involve other parts of the nervous system.

“It is important to keep West Nile virus in mind in the summer and early fall when faced with unexplained neurological presentations such as encephalitis and paralysis, not only to guide investigations, but to identify those who may benefit from available therapies,” says Dr. Cheryl Jaigobin, a professor in the Department of Medicine at the University of Toronto and a neurologist at the University Health Network. Jaigobin co-authored the study with Dr. Jodie Burton, a senior neurology resident.



Data from the WNV outbreak in Toronto indicate that more than 50 per cent of the 26 WNV patients admitted to four Toronto tertiary-care facilities in August and September 2002 had neurological disease. Seventy-eight per cent had encephalitis and, of those, 82 per cent developed neuromuscular dysfunction within days.

The Toronto experience was similar to earlier experiences of WNV infection in New York City, Israel, Louisiana and Cleveland. In all cases, advanced age and a compromised immune system were associated with a worse outcome.

The study’s authors recommend that physicians follow the currently accepted WNV testing regimen. They also suggest that electrodiagnostic testing be performed in patients with unexplained weakness and in those who are critically ill to rule out acute flaccid paralysis syndrome, a severe neuromuscular complication of the disease which may lead to prolonged disability or death.

Im Focus: MPSD team discovers light-induced ferroelectricity in strontium titanate

Light can be used not only to measure materials’ properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as its ability to conduct electricity or to store information in its magnetic state. A team led by Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg used terahertz frequency light pulses to transform a non-ferroelectric material into a ferroelectric one.

Ferroelectricity is a state in which the constituent lattice “looks” in one specific direction, forming a macroscopic electrical polarisation. The ability to...

Im Focus: Determining the Earth’s gravity field more accurately than ever before

Researchers at TU Graz calculate the most accurate gravity field determination of the Earth using 1.16 billion satellite measurements. This yields valuable knowledge for climate research.

The Earth’s gravity fluctuates from place to place. Geodesists use this phenomenon to observe geodynamic and climatological processes. Using...

Im Focus: Tube anemone has the largest animal mitochondrial genome ever sequenced

Discovery by Brazilian and US researchers could change the classification of two species, which appear more akin to jellyfish than was thought.

The tube anemone Isarachnanthus nocturnus is only 15 cm long but has the largest mitochondrial genome of any animal sequenced to date, with 80,923 base pairs....

Im Focus: Tiny light box opens new doors into the nanoworld

Researchers at Chalmers University of Technology, Sweden, have discovered a completely new way of capturing, amplifying and linking light to matter at the nanolevel. Using a tiny box, built from stacked atomically thin material, they have succeeded in creating a type of feedback loop in which light and matter become one. The discovery, which was recently published in Nature Nanotechnology, opens up new possibilities in the world of nanophotonics.

Photonics is concerned with various means of using light. Fibre-optic communication is an example of photonics, as is the technology behind photodetectors and...
