Cervical cancer - Animation

Worldwide, cervical cancer is the third most common type of cancer in women. Luckily, it's much less common in the United States due to women receiving recommended routine Pap smears, the test designed to find cervical cancer sometimes even before abnormal cells turn to cancer. Cervical cancer starts in the cells on the surface of the cervix, the lower portion of the uterus. There are two types of cells on the surface of the cervix, squamous and columnar. Most cervical cancers come from these squamous cells. The cancer usually starts very slowly as a condition called dysplasia. This precancerous condition can be detected by Pap smear and is 100% treatable. Undetected, precancerous changes can develop into cervical cancer and spread to the bladder, intestines, lungs, and liver. It can take years for these precancerous changes to turn into cervical cancer. However, patients with cervical cancer do not usually have problems until the cancer is advanced and has spread. Most of the time, early cervical cancer has no symptoms. Symptoms of advanced cancer may include back pain, bone fractures, fatigue, heavy vaginal bleeding, urine leakage, leg pain, loss of appetite, and pelvic pain. If after having a Pap smear, the doctor finds abnormal changes on the cervix, a colposcopy can be ordered. Using a light and a low-powered microscope, the doctor will view the cervix under magnification. The doctor may remove pieces of tissue, called a biopsy, and send the sample to a laboratory for testing. If the woman is diagnosed with cervical cancer, the doctor will order more tests to determine how far the cancer has spread. This is called Staging. Treatment will depend on the stage of the cancer, the size and shape of the tumor, the woman's age and general health, and her desire to have children in the future. Early cervical cancer can be treated with surgery just to remove abnormal tissue, freeze abnormal cells, or burn abnormal tissue. Treatment for more advanced cervical cancer may include radical hysterectomy, removal of the uterus and much of the surrounding tissue, including lymph nodes and the upper part of the vagina. Radiation may be used to treat cancer that has spread beyond the pelvis, or if cancer returns. The woman may also have chemotherapy to kill cancer cells. Almost all cervical cancers are caused by human papilloma virus, or HPV. This common virus is spread through sexual intercourse. HPV vaccines can prevent infection. Practicing safe sex also reduces the risk of getting HPV. But, keep in mind most women diagnosed with cervical cancer have not had their regular Pap smears. Because Pap smears can find precancerous growths that are 100% treatable, it's very important for women to get Pap smears at regular intervals.

What is tennis elbow? - Animation

I'm Dr. Alan Greene and let's talk for a moment about tennis elbow. Tennis elbow is a kind of tendonitis. It's an inflammation and injury to the tendons usually on the outside of the elbow. Tendons are those fibrous bands that connect the muscle into the bone. When those tendons get damaged, as they often can in racquet sports or also in baseball, sometimes over using a screwdriver, a lot of ways you can do it, we typically call it tennis elbow or tendonitis. How do you prevent it? When you are playing tennis one of the most important things is to avoid putting too much stress on that tendon on the outside of the elbow. The problem usually comes with your backhand. So if you do a two-handed backhand, you can greatly reduce the stress. You can also reduce the stress by using a racquet that has the right size grip for your hand. Don't play with somebody else's racquet very often. And make sure the strings are not over tightened. It puts too much stress when the ball hits suddenly with over tightened strings. If you have a tendency to get tennis elbow, it could also be very useful immediately after playing to ice the elbow and take some ibuprofen to prevent swelling and inflammation. Now, if you do develop tennis elbow how do you treat it? It comes down to a combination of rest, ice, compression, and elevation. In terms of rest, you want to completely rest your elbow for at least a couple of days and really for as long as it is still sore. In terms of ice that first day, ice very frequently. It's great even every 15 minutes to have an ice pack on there briefly and for the next couple of days, at least every 3 or 4 hours if you can. It will help speed the healing. Wearing a bandage on there to help support the elbow is good. It can also be good when you are playing tennis to help prevent tennis elbow. The wrap on there can help support the elbow and keep it warm and make it less likely to injure. And finally when you are having the severe pain at the beginning especially, keeping your elbow elevated above your heart can help as well and hopefully this will get you back out and physically active again very quickly.

Venous insufficiency - Animation

If you have dull, aching, or cramping pain in your legs, and pain that gets worse when you stand, you may have a condition called venous insufficiency. In venous insufficiency, the veins in your legs have trouble sending blood back to your heart. Normally, valves in your legs keep your blood flowing back towards your heart so it doesn't collect in one place. But the valves in varicose veins are either damaged or missing. This causes your veins to remain filled with blood, especially when you're standing. A blockage in your vein from a blood clot, called a deep venous thrombosis, can also cause this problem. So, how do you know if you have venous insufficiency?Well, you'll probably feel a dull aching, heaviness, or cramping in your legs. Your legs will swell up when you're on them too long. Your legs may itch or tingle. Pain will get worse when you stand, and better when you raise your legs. Your legs and ankles may also be red. You may notice skin color changes around your ankles. You may see varicose veins on the surface of your legs. You may feel thickening and hardening of the skin on your legs and ankles. So, what can you do about venous insufficiency?Well, your doctor will tell you to use compression stockings to decrease the swelling in your legs. You'll probably have to avoid long periods of sitting or standing. Even moving your legs slightly will help the blood in your veins return to your heart. Walking helps in that same way. Your doctor may recommend surgery or other treatments for varicose veins if you've tried everything and you still have leg pain that feels heavy or tired, skin ulcers or sores caused by poor blood flow. If blood clots are causing you problems, your doctor may prescribe anticoagulant or blood-thinning medicines, to treat existing blood clots and prevent others. Your doctor may suggest you try to keep your legs elevated above your heart when you lie down. You may improve your circulation through exercise. And finally, if you need to lose weight, weight loss can be a very helpful treatment of venous insufficiency and swelling.
