Human immunodeficiency virus infection / acquired immunodeficiency syndrome (HIV/AIDS) is a disease of the human immune system caused by the human immunodeficiency virus (HIV).[1] During the initial infection a person may experience a brief period of influenza-like illness. This is typically followed by a prolonged period without symptoms. As the illness progresses it interferes more and more with the immune system, making people much more likely to get infections, including opportunistic infections, and tumors that do not usually affect people with working immune systems.
HIV is transmitted primarily via unprotected sexual intercourse (including anal and even oral sex), contaminated blood transfusions and hypodermic needles, and from mother to child during pregnancy, delivery, or breastfeeding.[2] Some bodily fluids, such as saliva and tears, do not transmit HIV.[3] Prevention of HIV infection, primarily through safe sex and needle-exchange programs, is a key strategy to control the spread of the disease. There is no cure or vaccine; however, antiretroviral treatment can slow the course of the disease and may lead to a near-normal life expectancy. While antiretroviral treatment reduces the risk of death and complications from the disease, these medications are expensive and may be associated with side effects.
Genetic research indicates that HIV originated in West-central Africa during the early twentieth century.[4] AIDS was first recognized by the Centers for Disease Control and Prevention (CDC) in 1981 and its cause—HIV infection—was identified in the early part of the decade.[5] Since its discovery, AIDS has caused nearly 30 million deaths (as of 2009).[6] As of 2010, approximately 34 million people have contracted HIV globally.[7] AIDS is considered a pandemic—a disease outbreak which is present over a large area and is actively spreading.[8]
HIV/AIDS has had a great impact on society, both as an illness and as a source of discrimination. The disease also has significant economic impacts. There are many misconceptions about HIV/AIDS such as the belief that it can be transmitted by casual non-sexual contact. The disease has also become subject to many controversies involving religion.

Hey everyone! When I started posting more squat and lower-body workouts last week, I got many requests for this video. I actually had already had a knee pain video, but I felt like I could make it a lot better, so I remade it.

For more information, check out my friend ‎@ChrisRaynorMD aka @stablekneez on Instagram. Dr. Chris is a great surgeon, creative content creator, and all around good guy. He knows a LOT more than I do about this stuff. If you're interested, check him out!

Knee pain can be caused by MANY things, and this video is not intended to diagnose or treat any medical conditions. Some issues cannot be solved with exercise or physical therapy alone.

However, I've found that building up do doing squats with a full range of motion can help with knee pain. It's interesting, because there are some fitness figures that are adamantly against deep squatting because they claim it is BAD for the knees. I like it, and I've found it to be a very natural position. However, I do think that many people may not be prepared for it. Like any exercise, it can potentially hurt you if you're not acclimated to it. You can use your arm to assist you through the motion until you're able to do it without your arms with no pain. I have a full YouTube video on this: www.hybridcalisthenics.com/deepsquat.

Beyond this, sometimes strengthening our calves and hamstrings can "mysteriously" fix our knee pain. Both of these muscle groups support the knees.

On the other hand, sometimes these muscles are simply too TIGHT. You muscle fibers may be getting too tight and constantly trying to hyperextend your knees. Savor some calf and hamstring stretches.

I should point out that my chosen hamstring stretch in this video, standing toe touches, are controversial to some. Again, I like them, so they're shown here. If you are against them or they hurt you, you're very welcome to choose a different hamstring stretch.

Finally, I talk about isometric exercises like the horse stance and wall sit that seem to help with knee pain.

I touch upon synovial fluid, which is largely responsible for healing and nourishing our joints. Synovial fluid mostly circulates with movement, so I've included some knee "circles."

Hope this helps!

Although drug treatment of hypertension is associated with improved survival and decreased vascular complications, drug compliance is a major problem in the control of hypertension. All antihypertensive medications are associated with side effects; thus, it is a physician's responsibility to explain to each patient the side effects of the drugs he prescribes to treat hypertension, and to instill in the patient a sense of necessity for the treatment of hypertension. The choice of antihypertensive drug should be made based on each patient's lifestyle, overall health and ability to tolerate the drug. Ideally, the antihypertensive regimen should be simple, effective, convenient to take and have very few side effects.

The term hypoplastic left heart syndrome (HLHS), initially proposed by Noonan and Nadas, [1] describes a spectrum of cardiac abnormalities characterized by marked hypoplasia of the left ventricle and ascending aorta. This is the same disorder characterized as hypoplasia of the aortic tract complex by Lev. [2] The aortic and mitral valves are atretic, hypoplastic, or stenotic. A patent foramen ovale or an atrial septal defect is usually present. The ventricular septum is usually intact. A large patent ductus arteriosus supplies blood to the systemic circulation. Systemic arterial desaturation may be present because of complete mixing of pulmonary and systemic venous blood in the right atrium. Coarctation of the aorta is also commonly present. See the images below.

Majority of patients these days prefer PCNL ( Minimal Invasive Telescopic removal of kidney stones broken with lithoclast, removed through a button hole incision ). This patient with a big stone in the pelvis of the kidney wanted it open only so I did an open pyelolithotomy for this patient after a long time as I use to do it in routine in the past. Except for the long incision and scar as compared to PCNL the recovery time was the same and patient went home third day happily walking and eating.
