Peripheral arterial disease (P.A.D.) occurs when plaque (plak) builds up in the arteries that carry blood to your head, organs, and limbs. Plaque is made up of fat, cholesterol, calcium, fibrous tissue, and other substances in the blood. When plaque builds up in arteries, the condition is called atherosclerosis (ATH-er-o-skler-O-sis). Over time, plaque can harden and narrow the arteries. This limits the flow of oxygen-rich blood to your organs and other parts of your body. P.A.D. usually affects the legs, but also can affect the arteries that carry blood from your heart to your head, arms, kidneys, and stomach. This article focuses on P.A.D. that affects blood flow to the legs.

Limbal dermoid is a congenital growth on the eye that forms from germline cells that get trapped in this region during embryogenesis. The dermoid often has tissue from multiple germ layers including hair and fat. Dermoids on the eye can cause astigmatism and be unsightly.

Shoulder dystocia is a rare emergency that can happen during the end of the second stage of labour. It's all to do with how your baby moves down through your vagina and out into the world. Shoulder dystocia happens when your baby's head has been born, but one of her shoulders becomes stuck.

Most times, a pulmonary embolism is caused by blood clots that travel from the legs or, rarely, other parts of the body (deep vein thrombosis, or DVT). Symptoms include shortness of breath, chest pain, and cough. Prompt treatment to break up the clot greatly reduces the risk of death. This can be done with blood thinners and drugs or procedures. Compression stockings and physical activity can help prevent clots from forming in the first place.

Liposuction is a surgical procedure that is done to remove fat deposits from underneath the skin. Common areas that are treated: the abdomen, buttocks, thighs, upper arms, chest and neck. (use medical graphic of body with labeled parts) The procedure is usually done as an outpatient under some combination of local anesthesia and/or sedation:. This means you are awake but relaxed and pain free. Depending on the number of areas to be treated and the specific technique selected, it may take from one to several hours. A small incision (cut) is made through the skin near the area of the fat deposit. Multiple incisions may be needed if a wide area or multiple areas are being done. A long hollow tube called a cannula will be inserted through this incision. Prior to inserting the cannula, the doctor may inject a solution of salt water that contains an anesthetic (numbing) medication and another medication to decrease bleeding. The cannula is then inserted and moved under the skin in a way to loosen the fat deposits so they may be suctioned out. Because a significant amount of body fluid is removed with the fat, an intravenous (through the veins) fluid line will be kept going during the procedure.

A recent technique called “ultrasound-assisted lipoplasty” uses a special cannula that liquefies the fat cells with ultrasonic energy. You should ask your doctor which technique he/she will use and how it will affect the type of anesthesia you will need and the length of the procedure.

Why is this procedure performed?
Liposuction is done to restore a more normal contour to the body. The procedure is sometimes described as body sculpting. It should be limited to fat deposits that are not responsive to diet and exercise. It is suggested that you should be within 20of your ideal body weight at the time of surgery. If you are planning to lose weight you should delay this procedure. This is not obesity surgery. The maximum amount of fat that can be removed is usually less than 10 pounds. The best results are achieved in people who still have firm and elastic skin. Although rare, there are risks and complications that can occur with liposuction. You should be aware that all the complications are increased if you are a smoker. You will need to quit smoking or at least avoid smoking for a month before and after surgery. If you have had prior surgeries near any of the areas to be treated, this may increase the risk of complications and you should discuss this with your doctor. Any history of heart disease, diabetes, bleeding problems or blood clots in your legs may make you more prone to post-operative problems and you should discuss these with your doctor. Finally, as with any cosmetic procedure it is important to have realistic expectations. The goals, limitations, and expectations of the procedure should be discussed openly and in detail with your doctor. Most insurance companies do not cover cosmetic surgery.

What should I expect during the post-operative period?
After surgery you should be able to go home but you will need someone to drive you. In the first few days after surgery it is common for the incisions to drain fluid and you will have to change dressings frequently. Fresh blood is not usual and if you have any bleeding you should call your doctor immediately. In some cases a small tube may have been placed through the skin to allow drainage. You will be limited to sponge baths until the drains and dressings are removed. After that you may take showers but no baths for 2 weeks. You may experience pain, burning, and numbness for a few days. Take pain medicine as prescribed by your doctor. You may notice a certain amount of bruising and swelling. The bruising will disappear gradually over 1 to 2 weeks. Some swelling may last for up to 6 months. If you have skin sutures they will be removed in 7 to 10 days. You should be able to be up and moving around the house the day after surgery but avoid any strenuous activity for about 1

Many mothers notice engorgement, or over-filled breasts, at some point or the other while they are breast-feeding their baby and it is especially common to experience when your baby is first born and you are just starting to make milk. So for the first couple of days you make colostrum and then 2-5 days later your milk comes in. And sometimes it comes in with a vengeance and all of the sudden you feel really full and it can be painful and very uncomfortable. Normally your milk supply will even out and start to work well with your babys demand, so it is kind of a supply and demand type of function, but until then, if you feel engorgement, there are a few things you can do to relieve it. If you are nursing your baby on demand this will usually help to self-regulate and most young babies want to eat every 2-3 hours and sometimes even every hour. So, basically, the more often your breasts are emptied the more relief you will feel. But on the same hand, the more you nurse the more milk your body will probably produce. This is why it is good to go off of your babys cues because then you will make what your baby needs and hopefully not much more. But if you are making more than your baby needs and you find that you are still full after feedings you will probably have to either manually express some milk or pump it off, so have a good pump available in case you need to, and if you don't, you can manually express the milk by gently massaging from the armpit down towards the nipple. And you can also try using heat prior to nursing your baby or pumping milk off and this will also help to relax things and help you to get the milk out. Take a warm shower and then feed your baby or use a warm compress.

Bariatric surgical procedures cause weight loss by restricting the amount of food the stomach can hold, causing malabsorption of nutrients, or by a combination of both gastric restriction and malabsorption. Bariatric procedures also often cause hormonal changes. Most weight loss surgeries today are performed using minimally invasive techniques (laparoscopic surgery). The most common bariatric surgery procedures are gastric bypass, sleeve gastrectomy, adjustable gastric band, and biliopancreatic diversion with duodenal switch. Each surgery has its own advantages and disadvantages.

This test stimulates your acoustic nerve by delivering cold or warm water or air into your ear canal. When cold water or air enters your ear and the inner ear changes temperature, it should cause fast, side-to-side eye movements called nystagmus. The test is done in the following way: Before the test, your ear, especially the eardrum, will be checked. This is to make sure it is normal. One ear is tested at a time. A small amount of cold water or air is gently delivered into one of your ears. Your eyes should show an involuntary movement called nystagmus. Then they should turn away from that ear and slowly back. If water is used, it is allowed to drain out of the ear canal. Next, a small amount of warm water or air is gently delivered into the same ear. Again, your eyes should show nystagmus. Then they should turn toward that ear and slowly back. Your other ear is tested in the same way.

Thalassemia (thal-uh-SEE-me-uh) is an inherited blood disorder characterized by less hemoglobin and fewer red blood cells in your body than normal. Several types of thalassemia exist, including alpha-thalassemia, beta-thalassemia intermedia, Cooley's anemia and Mediterranean anemia. Hemoglobin is the substance in your red blood cells that allows them to carry oxygen. The low hemoglobin and fewer red blood cells of thalassemia may cause anemia, leaving you fatigued. If you have mild thalassemia, you may not need treatment. But, if you have a more severe form of thalassemia, you may need regular blood transfusions. You can also take steps on your own to cope with fatigue, such as choosing a healthy diet and exercising regularly.

Bipolar disorder, also known as manic-depressive illness, is a brain disorder that causes unusual shifts in mood, energy, activity levels, and the ability to carry out day-to-day tasks. There are four basic types of bipolar disorder; all of them involve clear changes in mood, energy, and activity levels.

The menstrual cycle is the monthly series of changes a woman's body goes through in preparation for the possibility of pregnancy. Each month, one of the ovaries releases an egg — a process called ovulation. At the same time, hormonal changes prepare the uterus for pregnancy.

Posterior dislocations with associated fractures, also known as complex posterior dislocations, often require open reduction and fixation (ORIF). These dislocations are often associated with significant ligamentous injury. In some cases, complex posterior elbow dislocations may be managed with closed reduction. Posterior elbow dislocations that are neglected, as is not uncommon in developing countries, can often be effectively treated with open reduction. [9] Delayed vascular compromise is an important complication after reduction. All patients should be observed for a period of approximately 2-3 hours after reduction. If no evidence of vascular compromise arises, patients can be sent home with appropriate follow-up and instructions to watch for further problems.
