Extractions: COXSACKIE VIRAL INFECTIONS HAND, FOOT AND MOUTH DISEASE What is it? This is a common viral infection that predominantly affects toddlers and school age children, and occurs most often in the summer and fall months (May through October). The following are the most typical features: Þ Ulcers in the mouth, usually about 4-8 mm in size, and predominantly located on the tongue and insides of the cheeks. These ulcers are mildly to moderately painful. Þ Small white blisters or red spots on the hands and feet, usually on the palms and soles, and in between the fingers. These are often tender. They do not itch as in chickenpox. Hands are more often involved than feet. Þ Occasionally, blisters or red spots can also occur on the buttocks, genitalia and extremities. Þ Fever, which is low to moderate range (100° to 102° ) usually, but can be higher.

Search the GSJ Brown researchers use interferon to peer into reactions that control immune responses to viral infections By studying the biology and biochemistry behind the cellular signaling and receptor systems of Type 1 interferons, the researchers unraveled some of the mechanisms behind how the compounds start a cascade of responses inside a cell. by Scott J. Turner Scientists at Brown and at the National Institutes of Health have produced greater insight into the complex physical interactions that control the immune responses to infections. Their study may lead to more judicious design of therapeutic cytokines, which are soluble compounds released by a variety of cells, including cells of the immune system. Cytokines act to regulate immune responses. Some cytokines, such as interferon and interleukins, are used to treat cancer, multiple sclerosis, viral infections and other illnesses. The findings appear in the September 20 issue of Science. The lead author of the study is Khuong Nguyen, a former doctoral student in immunology who graduated last May. The senior author is Christine A. Biron, chair of the Department of Molecular Microbiology and Immunology. By studying the biology and biochemistry behind the cellular signaling and receptor systems of Type 1 interferons, a long-known family of cytokines induced during viral infections, the researchers unraveled some of the mechanisms behind how the compounds start a cascade of responses inside a cell.

Extractions: Hundreds of viruses infect humans causing diseases ranging from the common cold to ebola. Herein, the focus is on the herpes family of viruses, which are among the most common infections of mankind. There are eight different members of the herpes family based on our current understanding of this group of viruses that infect humans. These viruses and common diseases they cause (or are suspected to cause) are listed below. Table: Human Herpesviruses Virus Disease Herpes simplex virus -1 (HSV-1) Oral herpes (fever blisters) Herpes simplex virus -2 (HSV-2) Genital herpes Varicella-zoster virus (VZV) Chickenpox, shingles Epstein-Barr virus (EBV) Infectious mononucleosis Cytomegalovirus (CMV) Human herpesvirus-6 (HHV-6) Human herpesvirus-7 (HHV-7) Human herpesvirus-8 (HHV-8) After primary infection, all the herpes viruses enter a state of latency (dormancy), which occurs in various different cells or tissues (e.g. lymphocytes, epithelial cells, neuronal cells, etc.). Latency is life long. Given the right circumstances, the virus can surface again in its activated form, which is called reactivation . Containment of the primary infection, maintenance of latency, and thus prevention of reactivation is under control of the immune system (see below).

Medmicro Chapter 52 Chemotherapy of viral infections. A number of antiviral drugs have been formally licensedand are widely used for the chemotherapy of specific viral infections. http://gsbs.utmb.edu/microbook/ch052.htm
Extractions: Antiviral drugs specifically inhibit one or more steps of virus replication without causing unacceptable side effects. The approved antiviral drugs and the viruses and diseases they treat are amantadine and rimantadine (influenza A virus), ribavirin (respiratory syncytial virus), idoxuridine and trifluridine (topical treatment of herpetic keratitis), vidarabine and acyclovir (systemic treatment of herpes simplex virus and varicella-zoster virus infections), famciclovir and valaciclovir (oral treatment of varicella-zoster virus infections), ganciclovir and foscarnet (cytomegalovirus), and zidovudine, didanosine, zalcitabine and stavudine (human immunodeficiency virus). To overcome the limitations of current antiviral drugs, more effective compounds are being developed that allow greater inhibition of viruses, greater selectivity for virus-specific functions, and fewer side effects, and may avoid emergence of resistant mutants. Specific events in virus replication identified as targets for antiviral agents are viral adsorption, penetration, uncoating, and viral nucleic acid synthesis as well as viral protein synthesis. Specificity for infected cells may occur when virus-specified enzymes (e.g., thymidine kinase-induced by herpes simplex virus or varicella-zoster virus) activate drugs (e.g., acyclovir).

Extractions: Persistent infections are characterized as those in which the virus is not cleared but remains in specific cells of infected individuals. Persistent infections may involve stages of both silent and productive infection without rapidly killing or even producing excessive damage of the host cells. There are three types of overlapping persistent virus-host interaction that may be defined as latent, chronic and slow infection. The mechanisms by which persistent infections are maintained involve both modulation of virus and cellular gene expression and modification of the host immune response. Reactivation of a latent infection may be triggered by various stimuli, including changes in cell physiology, superinfection by another virus, and physical stress or trauma. Host immunosuppression is often associated with reactivation of a number of persistent virus infections. Some viruses can establish persistent infection at the same time in different cell types of one or more tissues or organs. For example, the primary site for latency of cytomegalovirus is thought to be peripheral blood monocytes, but the virus may induce disease and can be detected in cells of several organs (e.g., kidney, lung, and those of the digestive or central nervous system). Table-1 categorizes selected human viruses by organ systems in which the virus is believed to be primarily persistent.
Clinical Viral Infections And Multiple Sclerosis viral infections Multiple Sclerosis. Sibley WA, Bamford CR, Clark K Lancet1985 Jun 8;1(8441)13135 PMID 2860501, UI 85212789 Abstract. http://www.albany.net/~tjc/viral-ms.html
Extractions: Abstract Over an 8 year period, 170 patients with Multiple Sclerosis ( MS ) and 134 healthy controls were assessed at monthly intervals in order to ascertain environmental factors. Which might be important in producing exacerbation or progression of the illness, and to compare the frequency of common Viral Infections in the two groups. During cumulative periods designated "at risk" (2 weeks before the onset of infection until 5 weeks afterwards) annual exacerbation rates were almost 3-fold greater than those during periods not at risk. Approximately 9% of infections were temporally related to exacerbations, whereas 27% of exacerbations were related to infections. Frequency of common infections was approximately 20-50% less in MS patients than controls; it was progressively less in those with greater disability. Even in minimally disabled patients with similar potential for infectious contacts, the infection rate was significantly less than in controls, suggesting that MS patients could have superior Immune defences against common Viruses.
Extractions: Infections of the eye and adnexa represent a significant source of ocular morbidity. Viral infections are seen commonly in optometric practice, although a wide array of presentations may be encountered. These may range from mild, self-limiting adenoviral conjunctivitis to sight-threatening herpetic keratitis or herpetic uveitis. It is crucial for eye care practitioners to recognize the various forms of viral ocular infection, and to understand the associated pathology and available treatment modalities. Although there are innumerable viral entities known to infect the human host, the eye is commonly susceptible to only a few. The adenoviruses, herpes simplex, and herpes zoster are by far the most notable; other less commonly encountered entities include the enteroviruses, Epstein-Barr virus, measles, mumps, and rubella.

Extractions: University of Iowa Young children are highly sensitive to viruses. Their resistance to infectious agents may still be low at the same time as their exposure to them increases. A virus can enter the body in many ways besides food, fluids, and bites from insects or animals. The infectious secretions from viruses are passed on to others by coming in contact with them. They can be inhaled from airborne particles from coughs and sneezes. Touching or holding hands with an infected person and then rubbing the eyes or nose is a common way to "catch" a virus. Viral particles may be on surfaces of toys, doorknobs, tables, or telephones. There are approximately 200 known viruses that cause disease in humans. Over 100 of these cause "colds." Viruses attack different parts of the body to produce different problems. Some cause a sore throat, cough, runny nose, headache, or muscle ache. Others cause abdominal symptoms such as nausea, cramping, and diarrhea. Other examples of viral infections in children include specific viral syndromes such as: Many viruses are hard to destroy without damaging or killing the living cells they infect, this is why drugs are not used to control them. Many viral diseases can be prevented by immunization.

Viruses are not complete cells, but tiny particles measuring about 0.00002 mm to 0.00003 mm. They cannot live on their own. They are made up of genetic material, surrounded by a protein coat. enzymes to detach themselves, and move away to infect other cells. Viral infections We have all suffered from infections caused by a virus However, influenza (flu) can be a more serious viral problem, especially in the elderly. Childhood diseases like measles, mumps and chickenpox are also caused by viruses. So are cold sores (herpes), shingles and AIDS (Acquired Immune Deficiency Syndrome), which is caused by HIV (human immunodeficiency virus). How were viruses discovered? Viruses were discovered when it was realised that the antibiotics of the 1940s and 1950s were not effective in some infectious diseases. (Only diseases caused by bacteria can be treated by antibiotics). Immunisation In the past, viral infections were successfully treated by immunisation smallpox Viral diseases such as smallpox and polio have been eradicated by immunisation. But, although immunisation has worked well against some viruses, it has completely failed so far against others such as the human immunodefficiency virus (HIV).

Extractions: Discuss the role of serology in virus diagnosis in the early 21st century Serology remains the mainstay for the diagnosis of virus infections in a routine diagnostic laboratory. There are 3 basic categories of methods used in the diagnosis of virus infections;- 1. Direct examination 2. Indirect examination 3. Serology Direct examination Indirect examination The virus in the clinical specimen is amplified by growing in tissue culture, eggs or animals. Cell culture is by far the most commonly used method. The presence of growing virus may be revealed by changes such as cytopathic effect (CPE) or the ability to haemadsorb. The identity of the isolated virus can be further confirmed by various tests eg. virus neutralization, immunofluorescence, complement-fixation, electron microscopy etc. The obvious disadvantage of virus isolation is the length of time required for the CPE or the ability to haemadsorb to become apparent, which may take from a few days to a few weeks. Longer, if confirmatory tests such as virus neutralization are to be carried out. However, rapid culture methods such as the DEAFF tests for CMV are becoming available whereby the cell culture is examined for the presence of CMV early antigens by fluorescent antibody technique. Another problem with virus culture is that the sensitivity is often low and depends on a large extent the quality of the clinical specimen received. Also, virus isolation would not be applicable to viruses which are difficult or cannot be cultivated such as hepatitis B and parvovirus.
