Eric knew he needed help when an old knee injury began worsening over the course of time and was significantly affecting his quality of life. That’s when he turned to his hometown orthopedic experts at Mayo Clinic Health System in Mankato, who recommended a total knee replacement. After overcoming some initial fears, Eric decided it was time to have the operation — a fuller and more active life with his family depended on it.

Your body's immune system protects you from disease and infection. But if you have an autoimmune disease, your immune system attacks healthy cells in your body by mistake. Autoimmune diseases can affect many parts of the body. No one is sure what causes autoimmune diseases. They do tend to run in families. Women - particularly African-American, Hispanic-American, and Native-American women - have a higher risk for some autoimmune diseases. There are more than 80 types of autoimmune diseases, and some have similar symptoms. This makes it hard for your health care provider to know if you really have one of these diseases, and if so, which one. Getting a diagnosis can be frustrating and stressful. Often, the first symptoms are fatigue, muscle aches and a low fever. The classic sign of an autoimmune disease is inflammation, which can cause redness, heat, pain and swelling. The diseases may also have flare-ups, when they get worse, and remissions, when symptoms get better or disappear. Treatment depends on the disease, but in most cases one important goal is to reduce inflammation. Sometimes doctors prescribe corticosteroids or other drugs that reduce your immune response.

Acute sinusitis can be triggered by a cold or allergies and may resolve on its own. Chronic sinusitis lasts up to eight weeks and may be caused by an infection or growths. Symptoms include headache, facial pain, runny nose, and nasal congestion. Acute sinusitis usually doesn't require any treatment beyond symptomatic relief with pain medications, nasal decongestants, and nasal saline rinses. Chronic sinusitis may require antibiotics.

A Brazilian butt lift (BBL) uses a person's own fat to enhance the size and shape of the buttocks. A plastic surgeon first performs liposuction to remove fat from other areas of the body (often the stomach, hips, and thighs), then injects that fat into the backside. Additional liposuction can be done around the butt to improve the appearance of lift and contour.

CTR is a surgery in which the narrowed part of the airway just below the voice box (larynx) is removed and the voice box and windpipe (trachea) are sewn back together. It is also used to treat other airway problems.

Multiple endocrine neoplasia type 2 (MEN2) is a hereditary condition associated with three primary types of tumors: medullary thyroid cancer, parathyroid tumors, and pheochromocytoma. MEN2 is classified into three subtypes based on clinical features. MEN2A, which affects 60% to 90% of MEN2 families Medullary thyroid cancer: 98% to 100% with MEN2A are affected Pheochromocytoma, a typically benign (noncancerous) tumor of the adrenal glands: 50% with MEN2A affected Parathyroid adenoma (benign tumor) or hyperplasia, meaning increased size, of the parathyroid gland: 5% to 10% with MEN2A affected MEN2B, which affects 5% of MEN2 families Medullary thyroid cancer: 98% to 100% with MEN2B affected Pheochromocytoma: 50% with MEN2B affected Mucosal neuromas, which is a benign tumor of nerve tissue on the tongue, lips and throughout the gastrointestinal tract: 95% to 98% affected Digestive problems caused by disordered nerves in the gastrointestinal tract: 75% to 90% affected Muscle, joint, and spinal problems: 95% affected Typical facial features, including swollen lips and thick eyelids: 75% to 90% affected Familial medullary thyroid cancer (FMTC), which affects 5% to 35% of MEN2 families Medullary thyroid carcinoma only Sources: Gagel RF, Marx SJ. “Multiple endocrine neoplasia.” Williams Textbook of Endocrinology, Chapter 40, 11th ed., Philadelphia, 2008, and Eng C, Clayton D, et al. Grubbs EG, Gagel RF. My, How Things Have Changed in Multiple Endocrine Neoplasia Type 2A! J Clin Endocrinol Metab 100(7):2532-5, 7/2015. PMID: 26151398. What causes MEN2? MEN2 is a genetic condition. This means that the cancer risk and other features of MEN2 can be passed from generation to generation in a family. The gene associated with MEN2 is called RET. A mutation (alteration) in the RET gene gives a person an increased risk of developing medullary thyroid cancer and other tumors associated with MEN2.

What Happens During an Erection?
In order to attain an erection, messages from the brain and other sense organs trigger the arteries of the penis to dilate. This allows an increased amount of blood to flow into three columns of spongy tissue in the penis.

As the arteries supplying blood to the corpus spongiosum and to the two larger columns, the corpus cavernosa, become filled with blood; the penis grows and becomes rigid. Pressure of the engorged tissue against the veins in the penis effectively traps blood within the penis until climax is reached or the sensation wanes.

What Are Penile Implants?
Impotence, or the inability to attain or maintain an erection, can be caused by a disruption at any stage in this process. Several types of penile implants are available that create an artificial erection. Two common types of implants are the semi-rigid malleable rod and the inflatable implant.

•The semirigid malleable rod is usually made of plastic with a core of flexible wire. These rods can be bent down to conceal the penis under clothing or raised to form an artificial erection.


•The inflatable implant is more complex and involves several working parts: a reservoir of fluid that is implanted into the abdomen, a pump system located in the scrotal sac near the testes, and two inflatable cylinders.
How Penile Implants Help Erectile Fuctioning
In order to attain an erection, the scrotal pump must be squeezed repeatedly to propel fluid into the penile cylinders. When an erection is no longer desired, a release valve is pressed on the side of the pump and the cylinders deflate.
Before Having Penile Implant Surgery
Persons considering these types of implants should speak with their physician or healthcare professional about possible risks and complications.

Rubber band ligation is a procedure in which the hemorrhoid is tied off at its base with rubber bands, cutting off the blood flow to the hemorrhoid. This treatment is only for internal hemorrhoids. To do this procedure, a doctor inserts a viewing instrument (anoscope) into the anus. The hemorrhoid is grasped with an instrument, and a device places a rubber band around the base of the hemorrhoid. The hemorrhoid then shrinks and dies and, in about a week, falls off. A scar will form in place of the hemorrhoid, holding nearby veins so they don't bulge into the anal canal. The procedure is done in a doctor's office. You will be asked whether the rubber bands feel too tight. If the bands are extremely painful, a medicine may be injected into the banded hemorrhoids to numb them. After the procedure, you may feel pain and have a sensation of fullness in the lower abdomen. Or you may feel as if you need to have a bowel movement. Treatment is limited to 1 to 2 hemorrhoids at a time if done in the doctor's office. Several hemorrhoids may be treated at one time if the person has general anesthesia. Additional areas may be treated at 4- to 6-week intervals.

You may have heard that some positions, such as your partner on top (missionary position), are better than others for getting pregnant. In fact, there's no evidence to back these theories up. Experts just haven't done the research yet. What experts have done, though, is use scanning to show what's going on inside when you're doing the deed. The research looked at two positions: the missionary position and doggy style. (Doggy style being when you're on all fours, and your partner enters you from behind). Common sense tells us that these positions allow for deep penetration. This means that they're more likely to place sperm right next to your cervix (the opening of your uterus). The scans confirm that the tip of the penis reaches the areas between the cervix and vaginal walls in both of these positions. The missionary position allows the penis to reach the area at the front of the cervix. The rear entry position reaches the area at back of the cervix. It's amazing what some experts spend their time doing, isn't it! Other positions, such as standing up, or woman on top, may be just as good for getting sperm right next to the cervix. We just don't know yet. So, in the meantime, enjoy some variety in your sex life and keep it fun while you're trying for a baby. And talk to others who are hoping to get pregnant by joining our Actively trying group. Do I have to have an orgasm to conceive? Obviously, it's very important for your partner to reach orgasm if you are trying for a baby. There is no evidence, however, that you need to orgasm to conceive. The female orgasm is all about pleasure and satisfaction. It doesn't really help to get the sperm to the egg. Gentle contractions in your uterus can help the sperm along, but these happen without you having an orgasm. So, it's really not vital for you to reach orgasm after your partner, or even to reach orgasm at all, for you to conceive.

Rhabdomyolysis is a condition in which damaged skeletal muscle (Ancient Greek: rhabdomyo-) tissue breaks down rapidly (Greek –lysis). This damage may be caused by physical (e.g. crush injury), chemical, or biological factors. Breakdown products of damaged muscle cells are released into the bloodstream; some of these, such as the protein myoglobin, are harmful to the kidney and may lead to kidney dysfunction. The severity of the symptoms (which may include muscle pains, vomiting and confusion) depends on the extent of the muscle damage, and whether kidney failure develops. The mainstay of treatment is generous intravenous fluids, but could include dialysis or hemofiltration.

Rhabdomyolysis and its complications are significant problems for those injured in disasters such as earthquakes and bombing. Relief efforts in areas struck by earthquakes often include medical teams with skills and equipment for treatment of survivors with rhabdomyolysis. The disease and its mechanisms were first fully elucidated during the Blitz of London in 1941.

A leg ulcer is simply a break in the skin of the leg, which allows air and bacteria to get into the underlying tissue. This is usually caused by an injury, often a minor one that breaks the skin. In most people such an injury will heal up without difficulty within a week or two. However, when there is an underlying problem the skin does not heal and the area of breakdown can increase in size. This is a chronic leg ulcer.
