Recommended: Causes and effects of HIV
“Human immunodeficiency virus (HIV) is a blood-borne virus typically transmitted via sexual intercourse, shared intravenous drug paraphernalia, and mother-to-child transmission (MTCT), which can occur during the birth processor during breastfeeding.” There is no cure for HIV or AIDS but over time different types of medications have been developed that slows down the advancement of the disease. AIDS is a lethal disease that is caused by HIV. HIV destroys the immune system and causes the body to not be able to fight off any diseases.
HIV goes through several different movements before it leads to AIDs. The first step is the serioconversion illness. This symptoms of this illness is very similar to the flu and an affected individual will typically experience this 1-2 months after connection with HIV. The next phase is asymptomatic infection in which the patient does not have any symptoms. During this step the immune system is starting to go downhill. A great deal depends on how long this phase will last such as, how fast the HIV virus replicates and how the patient’s body deals with the virus. Some patients can stay in this phase for almost 10 years without any signs or symptoms. Persistent generalized lymphadenopathy is when the lymph nodes become infected and enlarged. The HIV affected patient can endure swollen glands during any stage of the disease. The next phase of the disease is symptomatic infection. During this time symptoms will reveal themselves and often opportunistic infections, but AIDS has not developed yet (Masur H, 2007). The final phase is AIDS. The patient’s CD4 T-cell count is below 200 cells/mm3 and the patient is starting to have severe immunodeficiency. Patient begins to have severe opportunistic infections an...

It will be difficult for a HIV/AIDS patient to keep away from all of these different types of infections but constantly taking their antiretroviral medication is the first step. Routine physicals, blood tests, and eye examinations are significant because at times the patient may have no symptoms.

Bacteria vaginosis is treated with antibiotic medications (CDC). Metronidazole is commonly used. Metronidazole treatment does not adversely affect lactobacilli so they are able to recolonize the vagina and reduce the risk of late-stage relapse (Catlin, 1992). The cephalosporins available in the late 1970s were not very active against G. vaginalis.
For medical care, no treatment is needed for those who are asymptomatic, just monitoring for mild symptoms (2). For those who cannot fight the disease as easily as the majority, there are an array of treatments available. To start, blood cultures should be performed in all patients, and sputum cultures should be taken for those with chronic histoplasmosis (2). Chest radiology would be preferred for individuals with acute pulmonary histoplasmosis, steroids and possible laser treatment for ocular histoplasmosis, and CT scans for those with cerebral histoplasmosis (2). With prolonged symptoms of more than 4 weeks, medical therapy via itraconazole is recommended for 6-12 weeks, followed by chest imaging (2). Bronchiectasis caused by the microbe is treated with either a bronchoscopy or surgical removal (3). Phrenological treatments to histoplasmosis include amphorcetericin B, ketoconazole, itraconazole, and fluconazole (3). Currently, antifungal agents are being developed to offer alternative treatment (3). To successfully survive as a pathogen, the virus must change itself on a micro level to survive changing conditions, macrophages, and other threats to the fungi’s reproduction (4). Being able to go from an environmental mold to an intercellular yeast is extremely useful for a microbe in an ecosystem that fights for control of those it infects (4). These advantages present within histoplasmosis are what keeps it as a cause of respiratory and systemic disease in mammals (4). There are plenty of treatments available to accommodate all forms of histoplasmosis, making it a microbe that is very simple to cure, despite how hard it tries to
Human immunodeficiency virus infection / acquired immunodeficiency syndrome (HIV/AIDS) is a disease of the human immune system transmitted between people by the mixing of bodily fluids. It is an extremely deadly disease that has killed over thirty-six mi...
There are various types of aminoglycosides currently used, the most common being; amikacin, gentamicin, tobramycin and neomycin. The mechanism of action for all aminoglycosides is by inhibiting protein synthesis in the bacterial cell by binding to ribosome 30S sub unit ("amingolycosides,”). This is accomplished by passive diffusion across the bacterial cell membrane and then active transport across the cytoplasmic membrane to bind to ribosome 30S ("amingolycosides,”). Thus, inhibiting protein synthesis by inducing a misread of the genetic code mRNA. The entire process is oxygen dependent, which is why aminoglycosides are most effective against aerobic bacteria ("amingolycosides,”).
Candida can be obtained by rubbing a sterile cotton swab over the affected tissue lesions in the mouth and then inoculated in Sabouraud's dextrose agar (SDA). Another technique is using sterile foam pad that has been dipped in a liquid medium, such as Sabouraud's broth. The pad is then placed on the affected lesions in the mucosal cavity for 30 seconds and then transferred to an agar for culture. The last method is the oral rinse technique which require the patient to hold a sterile phosphate buffered saline in the mouth for one minute. The solution is then inoculated on an agar media at 37oC for 24-48 hours (1).

Human immunodeficiency virus (HIV) is a retro virus that causes AIDS. HIV is a virus that can only be contracted between human to human. HIV weakens your immune system because this virus is destroying cells that fight diseases and infection in your body. A virus can only produce itself by taking over a cell in the body of its h...
Human Immunodeficiency Virus (HIV) leads to the life threatening Acquired Immunodeficiency Syndrome (AIDS). HIV only lives in the blood and other bodily fluids. Concentrations of HIV are small in vomit, sweat, tears, and saliva and cannot be transmitted by those fluids. The main transmission is through fluids like semen, vaginal fluids, and rectal mucous during sexual contact, breast milk and amniotic fluid passing to children, and blood during transfusions and exposure. Beginning stages of HIV start with the acute infection. During the first 2 weeks to a month after exposure to the HIV infection, most infected individuals with display symptoms of a severe flu. The symptoms include fever, swollen glands, sore throat, rash, muscle and joint aches and pains, fatigue, and headache. The early period of infection is known as the “acute retroviral syndrome” (Stages, 2013). Once the virus is out of the acute stage it enters into the latency stage where it continues to replicate but no symptoms are shown. As the infection progresses and the immune system beco...
HIV is the human immunodeficiency virus; this virus can lead to acquired immune deficiency syndrome, or AIDS. Accoring to Avert, 2.6 million people became infected with HIV in 2009, there are now an estimated 33.3 million people around the world who are living with HIV. HIV is transmitted by the exchange of bodily fluids via sharing contaminated syringes, from infected mother to the child, and sexual contact. Contact with blood, semen, vaginal secretions, breast milk, or saliva that is contaminated with HIV, puts an individual at higher risk for contracting HIV. However, HIV cannot be transmitted by touch, coughing, or by bits from insect vectors.
Human Immunodeficiency Virus (HIV) is a virus that your body can’t get rid of. This virus sits in your body and attack your immune system and essential virus fighting cells. Acquired Immunodeficiency Syndrome (AIDS) is the final stage of HIV infection. At this point of HIV people have badly damaged immune systems, which put them at risk for other disease and infections.
...so that you can reduce your risk of being infected or spreading if you are already infected. Simply not having sex is the best way to not be infected. Limiting your partners, using a condom, being faithful are all ways to reduce your risk as well ("HIV Prevention," 2013). If have been diagnosed with HIV and want to keep you partner safe there are steps you can take to insure your partners’ health. There are medications called antiretroviral therapy or ART, that helps the body have less HIV in the body and this in turn reduces the risk for your partner ("HIV Prevention," 2013). There are also medications available for people who do not have HIV. PrEP, or Pre-exposure prophyraxis is taken by people who are at high risk of being infected, Post-exposure phrophytaxis is for people who have been exposed to HIV to reduce the risk of being infected ("HIV Prevention," 2013).
Acquired Immunodeficiency Syndrome (AIDS) first came to light in 1981. There has been a long and arduous global effort on the prevention of HIV/AIDS. HIV is a virus that is spread through body fluids that affect the specific T-cells of the immune system. Without treatment HIV infection leads to AIDS and there is no cure for AIDS. HIV infection can be controlled and the importance of primary pre...
Patient was previously treated with Remicade for sarcoidosis and had experienced some relief. After two weeks this benefit subsided and the patient has since then not improved. The initial dosing frequency of the Remicade was Q6W. The patient has a relative contraindication to corticosteroids due to diabetes.
HIV positive women were first reported in the late 1980s. AIDS is the final stage of HIV where the immune system is compromised. The virus causes severe damage to the immune system that even the simplest yeast infection can be deadly because the body will not have a functional immune system. HIV positive women who are still healthy and did not progress into AIDS, could have a normal pregnancy. However, HIV positive mothers could transmit the virus to their unborn child during pregnancy, this is known as mother to child transmission (MTC). Stoto states that in the United States, over 6,000 HIV infected women give birth every year and about one-third is estimated to give birth to HIV positive babies (Stoto1). HIV positive born children without any medication will not live up to an adolescent age and up to 50% can die within their first year. Stine points out without medication, “HIV-infected children lived to an average age of 9” (Stine 347). This became a serious concern in the scientific community due to the risks involved for the children.
The emergence of HIV/AIDS is viewed globally as one of the most serious health and developmental challenges our society faces today. Being a lentivirus, HIV slowly replicates over time, attacking and wearing down the human immune system subsequently leading to AIDS (Acquired Immunodeficiency Syndrome) at which point the affected individual is exposed to life threatening illnesses and eventual death. Despite the fact that a few instances of this disease have been accounted for in all parts of the world, a high rate of the aforementioned living with HIV are situated in either low or medium wage procuring nations. The Sub-Saharan region Africa is recognized as the geographic region most afflicted by the pandemic. In previous years, people living with HIV or at risk of getting infected did not have enough access to prevention, care and treatment neither were they properly sensitized about the disease. These days, awareness and accessibility to all the mentioned (preventive methods, care etc.) has risen dramatically due to several global responses to the epidemic. An estimated half of newly infected people are among those under age 25(The Global HIV/AIDS Epidemic). It hits hard as it has no visible symptoms and can go a long time without being diagnosed until one is tested or before it is too late to manage.
