Battles Over Insurance Reform Afflict House Dems
"House liberals are offended that Speaker Nancy Pelosi (D-Calif.) mocked their threats to oppose a Democratic healthcare bill, saying leaders are underestimating their frustration over a deal cut with centrist Blue Dogs," The Hill reports. "Rep. Lynn Woolsey (D-Calif.), co-chairwoman of the Congressional Progressive Caucus, on Monday expressed outrage at the comments and said her group is being "laughed at." Woolsey is the author of a letter signed by 60 fellow House liberals vowing to vote against a deal cut with the Blue Dogs ... Woolsey said the signers of the letter plan to "remind leadership" of the group"s support for a "robust public option." "Robust" to liberals generally means similar to Medicare. Liberals are irritated leaders granted Blue Dogs" concessions that prevent the public option from using Medicare rates for reimbursement. They believe that will make care too expensive for many people" (Soraghan and Allen, 8/3).

New Guideline For Low-Back Pain Interventions, Surgery Issued By The American Pain Society
The American Pain Society (APS) has issued a new clinical practice guideline for low back pain that emphasizes the use of noninvasive treatments over interventional procedures, as well as shared decision making between provider and patient. The findings are published in the current (May 1, 2009) issue of the journal Spine.

Illinois Counties Facing Increases In STDs Among Teenagers; Bill Aims To Reduce Rates
Illinois health officials contend that images seen in the media, social influences, and a lack of "frank" discussion on STDs in schools, among other issues, might be contributing to increases in STD rates across the state, the State Journal-Register reports. "According to recently released data, new cases of chlamydia in Illinois reached an all-time high statewide in 2008 - 59,169 - while the number of gonorrhea cases outside Chicago has been rising in recent years and totaled 10,165 in 2008," the Journal-Register reports. In addition, about 35,000 state residents have HIV/AIDS, the article states. Charlie Rabins, chief of the STD program at the Illinois Department of Public Health, said a bill (SB 212) currently awaiting Gov. Pat Quinn"s (D) approval might help reduce STD rates. The bill "would allow what is called "expedited partner therapy," in which medical professionals who treat patients for gonorrhea or chlamydia can give those patients single-dose antibiotics to pass on to sexual partners without first examining the partners," according to the Journal-Register (Olsen, 7/27).

What Is A Virus? What Is A Viral Infection?

A virus (from the Latin virus meaning toxin or poison) is a microscopic organism consisting of genetic material (RNA or DNA) surrounded by a protein, lipid (fat), or glycoprotein coat. Viruses are unique organisms because they cannot reproduce without a host cell. After contacting a host cell, a virus will insert genetic material into the host and take over the host"s functions. The cell, now infected, continues to reproduce, but it reproduces more viral protein and genetic material instead of its usual products. It is this process that earns viruses the classification of "parasite". How are viruses spread? Viruses may spread vertically (from mother to child) or horizontally (from person to person). A virus"s ability to spread depends on the makeup of the virus. Interesting articles What are bacteria? What is fungus? What are fungi? What is herpes? What is genital herpes? What is hepatitis? Symptoms, causes and treatments. What is swine flu? What is measles? What are the symptoms of measles? What is polio? What causes polio? What is flu (influenza)? What are the symptoms of flu? Some viruses can spread by simple contact, exchanges of saliva, coughing, or sneezing. Some require sexual contact, while others go through the fecal-oral route via contaminated food or water. Still other viruses require an insect like a mosquito to carry the virus from person to person. What diseases are caused by viruses? Several human diseases are caused by viruses. These include: *Smallpox *The common cold *Measles *Chickenpox *Hepatitis *Influenza *Human papilloma virus *Shingles *Herpes *Polio *Rabies *Ebola *Hanta fever *HIV (the virus that causes AIDS) *Cold sores *SARS (Severe acute respiratory syndrome) *Dengue *Epstein-Barr virus *Some types of cancer How do we fight viruses? When the body"s immune system detects a viral infection, it begins to respond in a generic way. A process begins called RNA interference, which is crucial to fighting viruses because it degrades the viral genetic material and enables cells to survive the infection. The immune system also produces specific antibodies that are capable of binding to viruses and making them non-infectious. In addition, the body"s T cells are sent to destroy the virus. Although most viral infections result in a protective response from the immune system, viruses such as HIV specialize in evading the immune system by using a number of different techniques. Neurotropic viruses are also very capable of avoiding our natural immune system"s response to infection. How are viruses prevented and treated? Whereas bacterial infections can be treated with antibiotics, viral infections require either vaccinations to prevent them or antiviral drugs to treat them. Vaccinations are generally the cheapest and most effect way to prevent viruses. Currently, vaccinations exist for polio, measles, mumps, rubella, and smallpox among others. In fact, vaccinations have been instrumental in eliminating diseases such as smallpox and reducing other viral diseases to extremely rare status. Virus vaccinations consist of a weakened form of the virus (live-attenuated viruses) or viral proteins called antigens. Live-attenuated vaccines carry the risk causing the original disease in people with weak immune systems. Antiviral drugs have been developed largely in response to the AIDS pandemic. These drugs do not destroy the pathogen but instead inhibit their development. Antiviral medications are relatively harmless to the host.
