If you go to research LASIK eye surgery online, you may get conflicting messages. Some articles rave about it, but in some cases, others link it to severe pain or even suicide. 7 Action News' Carolyn Clifford sat down with one of the area's biggest providers of eye surgery to try and separate fact from fiction, so if you go under the laser, you know the risk.

The two biggest considerations when choosing a suture are the location and tension of the wound. Other important considerations are tensile strength, knot strength, handling, and tissue reactivity. Sutures are divided into two major groups: Absorbable – lose the majority of their tensile strength in less than 60 days. They are generally used for buried sutures and do not require removal. Non-absorbable – maintain the majority of their tensile strength for more than 60 days. They are generally used for skin surface sutures and do require removal postoperatively. Suture needles also come in a variety of shapes and sizes. Curved needles are almost exclusively used in dermatological surgery. Cutting needles move through the tissue more easily and may have their primary cutting edge on the inside of the curve (conventional cutting) or outside of the curve (reverse cutting). The benefit of reverse cutting is that the tapered puncture left by the suture is directed away from the wound edge and therefore tissue tearing is less common. Non-cutting round needles cause even less tissue tearing and may be especially useful in delicate areas and fascia.

What is myositis? Myositis means muscle inflammation, and can be caused by infection, injury, certain medicines, exercise, and chronic disease. Some of the chronic, or persistent, forms are idiopathic inflammatory myopathies, and those are the diseases we discuss here. "Idiopathic" means that the cause is unknown.

Tonsillitis is inflammation of the tonsils, two oval-shaped pads of tissue at the back of the throat — one tonsil on each side. Signs and symptoms of tonsillitis include swollen tonsils, sore throat, difficulty swallowing and tender lymph nodes on the sides of the neck. Most cases of tonsillitis are caused by infection with a common virus, but bacterial infections also may cause tonsillitis. Because appropriate treatment for tonsillitis depends on the cause, it's important to get a prompt and accurate diagnosis. Surgery to remove tonsils, once a common procedure to treat tonsillitis, is usually performed only when bacterial tonsillitis occurs frequently, doesn't respond to other treatments or causes serious complications.

Your egg usually lives for just 12 to 24 hours, but sperm will live inside you for anything from a few hours to seven days, with one to three days the optimum time. ... But because a small number of sperm are long-living, having sex up to six days before ovulation can also result in pregnancy.

Your doctor says your chest pain (angina) is caused by blockages in your heart arteries and that you need to get those blockages taken care of. What are your options? First, it's important to determine what type of angina you have. Different types of angina may need different treatments. Common types of angina are chronic stable angina — a type of angina that occurs when your heart is working hard — and unstable angina, which is new chest pain or chest pain that is getting worse. Other types of angina include variant angina — a rare type of angina caused by a spasm in the coronary arteries — and microvascular angina, which can be a symptom of disease in the small coronary artery blood vessels. Unstable angina is a serious situation and requires emergency treatment. Treatment for unstable angina involves hospitalization with medications to stabilize your condition. Some people with unstable angina may require a procedure called angioplasty (also known as percutaneous coronary intervention), usually combined with the placement of a small metal tube called a stent. In some cases of unstable angina, heart surgery (coronary bypass surgery) may be needed. Generally, if you have mild stable angina that is controlled by medications, you may not need further treatments. If you're experiencing symptoms of chronic stable angina even after taking medications and making lifestyle changes, or if you're at higher risk of serious heart disease, your doctor may recommend angioplasty or coronary bypass surgery. Making a decision on how to treat your angina can be difficult, but knowing the benefits and risks of stents and medications may help you decide.

The arm and leg muscles are affected later. Myasthenia gravis (MG) is an autoimmune disease — a disease that occurs when the immune system attacks the body's own tissues. In MG, that attack interrupts the connection between nerve and muscle — the neuromuscular junction.

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.

On the day of your surgery, your health care team will take you to a preparation room. Your blood pressure and breathing will be monitored. You may receive an antibiotic medication through a vein in your arm. You will then be taken to an operating room and positioned on a table. You'll be given a general anesthesia medication to put you in a sleep-like state so that you won't be aware during your operation. The surgical team will then proceed with your colectomy. Colon surgery may be performed in two ways: Open colectomy. Open surgery involves making a longer incision in your abdomen to access your colon. Your surgeon uses surgical tools to free your colon from the surrounding tissue and cuts out either a portion of the colon or the entire colon. Laparoscopic colectomy. Laparoscopic colectomy, also called minimally invasive colectomy, involves several small incisions in your abdomen. Your surgeon passes a tiny video camera through one incision and special surgical tools through the other incisions. The surgeon watches a video screen in the operating room as the tools are used to free the colon from the surrounding tissue. The colon is then brought out through a small incision in your abdomen. This allows the surgeon to operate on the colon outside of your body. Once repairs are made to the colon, the surgeon reinserts the colon through the incision. The type of operation you undergo depends on your situation and your surgeon's expertise. Laparoscopic colectomy may reduce the pain and recovery time after surgery. But not everyone is a candidate for this procedure. Also, in some situations your operation may begin as a laparoscopic colectomy, but circumstances may force your surgical team to convert to an open colectomy. Once the colon has been repaired or removed, your surgeon will reconnect your digestive system to allow your body to expel waste. Options may include: Rejoining the remaining portions of your colon. The surgeon may stitch the remaining portions of your colon together, creating what is called an anastomosis. Stool then leaves your body as before. Connecting your intestine to an opening created in your abdomen. The surgeon may attach your colon (colostomy) or small intestine (ileostomy) to an opening created in your abdomen. This allows waste to leave your body through the opening (stoma). You may wear a bag on the outside of the stoma to collect stool. This can be permanent or temporary. Connecting your small intestine to your anus. After removing both the colon and the rectum (proctocolectomy), the surgeon may use a portion of your small intestine to create a pouch that is attached to your anus (ileoanal anastomosis). This allows you to expel waste normally, though you may have several watery bowel movements each day. As part of this procedure, you may undergo a temporary ileostomy.

Four-Step Guide to ABG Analysis Is the pH normal, acidotic or alkalotic? Are the pCO2 or HCO3 abnormal? Which one appears to influence the pH? If both the pCO2 and HCO3 are abnormal, the one which deviates most from the norm is most likely causing an abnormal pH. Check the pO2. Is the patient hypoxic?

irregular, curved toenails. footwear that places a lot of pressure on the big toes, such as socks and stockings that are too tight or shoes that are too tight, narrow, or flat for your feet. toenail injury, including stubbing your toe, dropping something heavy on your foot, or kicking a ball repeatedly. poor posture.

Transposition of the great arteries is a serious but rare heart defect present at birth (congenital), in which the two main arteries leaving the heart are reversed (transposed). Transposition of the great arteries changes the way blood circulates through the body, leaving a shortage of oxygen in blood flowing from the heart to the rest of the body. Without an adequate supply of oxygen-rich blood, the body can't function properly and your child faces serious complications or death without treatment.

Surfactant. Surfactants are compounds that lower the surface tension (or interfacial tension) between two liquids or between a liquid and a solid. Surfactants may act as detergents, wetting agents, emulsifiers, foaming agents, and dispersants.

Rehydration Tips: Kids & Teens (Ages 1+) Give clear liquids (avoid milk and milk products) in small amounts every 15 minutes. ... If your child vomits, start over with a smaller amount of fluid (2 teaspoons, or about 10 milliliters) and continue as above. ... After no vomiting for about 8 hours, introduce solid foods slowly.

Wilms tumor, also known as nephroblastoma, is a cancer of the kidneys that typically occurs in children, rarely in adults. It is named after Dr. Max Wilms, the German surgeon (1867–1918) who first described it. Approximately 500 cases are diagnosed in the U.S. annually.

Spinal stenosis can put pressure on the spinal cord and the nerves within the spine. It commonly occurs in the neck and lower back. The condition is often caused by age-related wear and tear. Symptoms, if they occur, include pain, numbness, muscle weakness, and impaired bladder or bowel control. Treatment includes medication, physical therapy, and possibly surgery

Bone tumors develop when cells in the bone divide without control, forming a mass of tissue. Most bone tumors are benign, which means they are not cancer and cannot spread. However, they may still weaken bone and lead to fractures or cause other problems. Bone cancer destroys normal bone tissue and may spread to other parts of the body (called metastasis). Benign Bone Tumors Benign tumors are more common than malignant tumors of the bones. These are a few common types of benign bone tumors: Osteochondroma is the most common benign bone tumor. It is more common in people under age 20. Giant cell tumor is a benign tumor, typically affecting the leg (malignant types of this tumor are uncommon). Osteoid osteoma is a bone tumor, often occurring in long bones, that occurs commonly in the early 20s. Osteoblastoma is a single tumor that occurs in the spine and long bones, mostly in young adults. Enchondroma usually appears in bones of the hand and feet. It often has no symptoms. It is the most common type of hand tumor.

The cell cycle or cell-division cycle is the series of events that take place in a cell leading to its division and duplication of its DNA (DNA replication) to produce two daughter cells.

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. http://www.babycentre.co.uk/sex-for-getting-pregnant#ixzz4XKnPLbxL
