AU - Cainelli, Francesca. AU - Baj, Andreina. AU - Temesgen, Zelalem. AU - Vento, Sandro. PY - 2009/1/1. Y1 - 2009/1/1. N2 - Viral encephalitis is worldwide spread pathology with high morbidity and mortality. Its incidence is higher in children. Enteroviruses, varicella zoster virus and herpes simplex viruses are the most frequent agents. However, in spite of the use of modern microbiological and radiological methods, an etiological diagnosis is reached in less than 50% of cases, making a careful differential diagnosis with non viral brain diseases imperative. Pathogenesis is elusive and therapy continues to remain supportive in almost all cases, as the only virus-directed treatment is available for herpesvirus-related encephalitis and a role for steroids continues to be debated. Novel and more targeted ...

Rocio viral encephalitis is an epidemic flaviviral disease of humans first observed in São Paulo State, Brazil, in 1975. Low-level enzootic transmission is likely continuing in the epidemic zone, and with increased deforestation and population expansion, additional epidemics caused by Rocio virus are highly probable. If migratory species of birds are, or become involved in, the virus transmission cycle, the competency of a wide variety of mosquito species for transmitting Rocio virus experimentally suggest that the virus may become more widely distributed. The encephalitis outbreak in the western hemisphere caused by West Nile virus, a related flavivirus, highlights the potential for arboviruses to cause severe problems far from their source enzootic foci. The causative Rocio virus belongs to the genus Flavivirus (the same genus as the Zika virus) in family Flaviviridae and is closely related serologically to Ilhéus, St. Louis encephalitis, Japanese encephalitis and Murray Valley encephalitis ...
Mosquito blood meals provide information about the feeding habits and host preference of potential arthropod-borne disease vectors. Although mosquito-borne diseases are ubiquitous in the Neotropics, few studies in this region have assessed patterns of mosquito-host interactions, especially during actual disease outbreaks. Based on collections made during and after an outbreak of equine viral encephalitis, we identified the source of 338 blood meals from 10 species of mosquitoes from Aruza Abajo, a location in Darien province in eastern Panama. A PCR based method targeting three distinct mitochondrial targets and subsequent DNA sequencing was used in an effort to delineate vector-host relationships. At Aruza Abajo, large domesticated mammals dominated the assemblage of mosquito blood meals while wild bird and mammal species represented only a small portion of the blood meal pool. Most mosquito species fed on a variety of hosts; foraging index analysis indicates that eight of nine mosquito species ...

In malaria-endemic areas, it is difficult to differentiate between cerebral malaria (CM), bacterial meningitis, and viral encephalitis. We examined the cerebrospinal fluid of 49 children who fulfilled the World Health Organizations (WHO) definition of CM and in 47 encephalopathic children, without malaria, looking for viruses with polymerase chain reaction. In the children with CM, four (9%) had evidence of Herpes simplex virus 1 in the cerebrospinal fluid, whereas in the encephalopathy group without malaria, six (12%) were positive. A significant proportion of children who fulfil the WHO clinical definition of CM may have viral encephalitis.
Rabies viral encephalitis, though one of the oldest recognized infectious disease remains an incurable, fatal encephalomyelitis despite significant advances in understanding of its pathobiology. Advances in science has led us to the trail of the virus in the host, but the sanctuaries in which the virus remains hidden or "latent" for its survival is unknown. Insights into host-pathogen interactions has facilitated evolving immunologic therapeutic strategies but we are far from finding a cure. To explain dichotomy in clinical presentation and uniform mortality in this viral encephalitis, various factors have been implicated that include both viral and host factors such as neuroanatomical distribution of viral antigen within brain, alteration in host immunity or viral strain in the former whereas apoptosis, neuronal dysfunction and neurotransmitter abnormalities in critical neuroanatomical areas are the popular explanations for the latter. Most of the present day knowledge has however evolved from ...
Using a genomics-based approach, Ganem and DeRisi have employed a DNA microarray that bears the telltale gene fragments of all known viruses of humans, animals, plants, and microbes on a microscopic slide. If a sample from a suspected viral genome has a chunk of genetic material that matches one on the slide, it will adhere to that spot and light up when the slide is put into a scanner. While the method is more likely to identify viral genomes related to known viruses, Ganem thinks it also will be useful for detecting novel viruses.. The team has already used this approach to identify the genome of the newly discovered SARS (severe acute respiratory syndrome) virus. They are now using the same technology to search for viruses that are more likely to cause severe upper respiratory infection in patients with asthma. Ultimately, Ganem hopes to determine whether viruses may be responsible for certain cancers and autoimmune diseases, including rheumatoid arthritis and multiple sclerosis, for which a ...

Individuals with encephalitis are usually hospitalized for treatment. The specific treatment is determined by the cause of the illness. Some viral infections are treatable with medication, and all patients are treated with supportive care until they recover. The patients chance of recovery depends on the specific cause of the illness and the severity of the swelling in the brain and surrounding tissues and fluids. The prognosis for viral encephalitis varies. Some cases are mild and patients recover fully. Other cases are more severe, and permanent damage or death is possible. The most severe phase of viral encephalitis may last for one to two weeks, with fever and neurologic symptoms improving gradually or suddenly. Neurologic symptoms may require many months before full recovery, and patients may require rehabilitative services. ...

Research in our laboratory is focused on the identification and characterization of novel viruses. This is motivated largely by the fact that the etiologies of many diseases remain cryptic; for example, 70% of cases of viral encephalitis and 30% of respiratory tract infections defy the most sophisticated diagnostic tests used today, suggesting that unknown agents are likely to be involved in the pathogenesis of these diseases. Furthermore, new emerging viruses (e.g. SARS) pose constant threats to public health. We have developed novel DNA microarray and high throughput sequencing approaches to identify novel viruses. These approaches enable systematic and unbiased screening of clinical specimens for the presence of microbial agents. To date, we have identified more than 40 novel viruses and are now working to characterize the molecular virology and clinical relevance of these viruses. One area of focus is analysis of the novel WU polyomavirus, which we discovered in 2007 in a child with ...
Neurological infections are relatively uncommon in Great Britain, Europe, and North America. The substantially widened differential diagnosis in a sick patient who has been abroad is particularly challenging. Viral encephalitis in terms of causes, investigation, and management is explored by researcher Peter Kennedy. Meningitis, with an emphasis on difficult and recurrent presentations, is considered by researcher Lionel Ginsberg. One difficult differential diagnosis of these infections is inflammatory or post-infectious encephalomyelitis or meningo-encephalomyelitis, and these are covered by researchers Luke Bennetto and Neil Scolding ...
I. Perioperative evaluation: Perioperative evaluation should focus on the location and causative agent of infection, if known, and the impact that the infection may have on organ function. Isolated infections will have little impact on anesthesia decision making unless there is a possibility of bacteremia or viremia. In the case of bacteremia, a single course of antibiotics will allow for regional anesthesia in most cases.. In the case of viremia, many experts would recommend that spinal anesthesia be avoided for fear of subsequent viral encephalitis or meningitis. Little data is available, however. It should be noted that in the absence of dural puncture, the likelihood of spreading virus particles into the CNS is very rare. In this case, epidural analgesia/anesthesia could still be considered.. Regional anesthesia is not contraindicated in patients with HIV infections that are stable. In most cases, CNS involvement occurs early in the course of HIV infection, even in the absence of symptoms. ...

Bickerstaff brainstem encephalitis is a rare inflammatory disorder of the central nervous system, first described by Edwin Bickerstaff in 1951. It may also affect the peripheral nervous system, and has features in common with both Miller Fisher syndrome and Guillain-Barré syndrome.[citation needed] In order to diagnose Bickerstaff brainstem encephalitis, ataxia and ophthalmoplegia must be present. These are also diagnostic features of Miller Fisher syndrome, and so Bickerstaffs is only diagnosed if other features are present which exclude Miller Fisher syndrome. These may include drowsiness, coma or hyperreflexia. When the condition is defined in this way, a number of other features are commonly but not always found: among these are weakness of the limbs, the face, and/or the bulbar muscles; abnormalities of the pupils; and absent reflexes. Like some other autoimmune diseases, the condition usually follows a minor infection, such as a respiratory tract infection or gastroenteritis. The ...
Herpes simplex virus type 1 is a cause more frequent and severe viral encephalitis. Encephalitis associated with herpes can become rapidly and can cause seizures or mental status changes, and even lead to coma and death. Occurs when the herpes simplex type I, the virus travels to the brain, rather than go through the body to the surface of the skin and produces its most common symptom, herpes. Early diagnosis and treatment of herpes simplex encephalitis can be life saving. There are more susceptible to encephalitis, if you have herpes ...
Magnetization transfer imaging represents an attempt to develop contrast in MR imaging on the basis of submolecular exchange processes that may occur in biological tissue (21). This technique has some clinical and research applications in the study of different CNS disorders (22), because it affords a potential window into the macromolecular environment that is not directly visible using conventional techniques (21). Therefore, it enables the assessment of "invisible" disease in the so-called normal-appearing white matter (23-25), and, with the application of MTR, it provides a means to quantify disease burden (26).. Experimental and human studies support the hypothesis that demyelination and axonal loss are the main contributors to the MTR decrease observed in association with several pathologic conditions, such as experimental autoimmune encephalomyelitis (12), toxic demyelination (27), progressive multifocal leukoencephalopathy (28), human immunodeficiency virus encephalitis (28), and ...
OBJECTIVE: To compare the cognitive defects after acute acyclovir treated herpes simplex encephalitis with those after other types of acute encephalitis. METHODS: Seventy seven consecutive patients between 1985 and 1995 and 29 normal controls were studied. Of the 77 patients without concomitant neurological conditions, 17 had herpes simplex, one virus encephalitis (HSVE group), 27 had some other identified aetiology (non-HSVE group), and in 33 patients the cause was unknown. Acyclovir treatment was started less than four days after the first mental symptoms in 12 of 17 patients with HSVE. A thorough neuropsychological assessment was carried out about one month after the onset. RESULTS: The HSVE group had deficits in verbal memory, verbal-semantic functions, and visuoperceptual functions more often than the non-HSVE group. The risk for cognitive defects was twofold to four-fold in the patients with HSVE compared with the non-HSVE patients. Two (12%) of the patients with HSVE and 12 (44%) of the ...
22 February is World Encephalitis Day. Founded by The Encephalitis Society four years ago, it aims to help raise awareness of the disease on an international scale.. In a nutshell, encephalitis refers to the inflammation of the brain. Up until recently, it was thought that encephalitis was simply either a viral or bacterial infection. However, in 2005, research described a new version of the disease: auto-immune or anti-NMDAR encephalitis, which is caused by antibodies that attack the brain tissue. In all its forms, encephalitis is incredibly rare: herpes simplex encephalitis (HSE), for instance, affects approximately one in 1,000,000 children. Although there are clear treatment routes available, viral encephalitis is incredibly destructive. The virus can cause irreversible damage in the brain, which will continue to impact upon a patients quality of life well after their short-term recovery from the disease itself.. Despite its often devastating consequences, the rarity of encephalitis might ...

TY - CHAP. T1 - The neuropathology of HIV. AU - Gelman, Benjamin B.. PY - 2007/12/1. Y1 - 2007/12/1. N2 - HIV encephalitis remains a prevalent and important neuropathological correlate of dementia in the HAART era. It is probably the only neuropathological variable that has undergone substantial independent verification in multiple autopsy cohorts. HIV encephalitis has provided the field with a unifying concept to pursue the pathophysiology of dementia. Drawbacks remain that the diagnosis is an overly diverse constellation of anomalies in both gray and white matter, and correlation with dementia remains too vague. The overall incidence of HIV-associated dementia in the HAART era declined by about half, but autopsy cohorts still exhibit a substantial prevalence of HIV encephalitis, probably because they are enriched with people with end-stage disease. The intensity of HIV encephalitis might have undergone a decrease in the HAART era, but HIV encephalitis remains essentially an "all or none" ...
