If you are self-conscious because you have missing teeth, wear dentures that are uncomfortable or don't want to have good tooth structure removed to make a bridge, talk to your dentist to see if dental implants are an option for you. Dental implants are a popular and effective way to replace missing teeth and are designed to blend in with your other teeth. They are an excellent long-term option for restoring your smile. In fact, the development and use of implants is one of the biggest advances in dentistry in the past 40 years. Dental implants are made up of titanium and other materials that are compatible with the human body. They are posts that are surgically placed in the upper or lower jaw, where they function as a sturdy anchor for replacement teeth.

Most people have general anesthesia right before surgery. This means you will be asleep and pain-free. Other kinds of anesthesia, like regional anesthesia or a block, may also be used for this surgery. The tissue to replace your damaged ACL will come from your own body or from a donor. A donor is a person who has died and chose to give all or part of his or her body to help others. Tissue taken from your own body is called an autograft. The two most common places to take tissue from are the knee cap tendon or the hamstring tendon. Your hamstring is the muscle behind your knee. Tissue taken from a donor is called an allograft. The procedure is usually performed with the help of knee arthroscopy. With arthroscopy, a tiny camera is inserted into the knee through a small surgical cut. The camera is connected to a video monitor in the operating room. Your surgeon will use the camera to check the ligaments and other tissues of your knee. Your surgeon will make other small cuts around your knee and insert other medical instruments. Your surgeon will fix any other damage found, and then will replace your ACL by following these steps: The torn ligament will be removed with a shaver or other instruments. If your own tissue is being used to make your new ACL, your surgeon will make a larger cut. Then, the autograft will be removed through this cut. Your surgeon will make tunnels in your bone to bring the new tissue through. This new tissue will be in the same place as your old ACL. Your surgeon will attach the new ligament to the bone with screws or other devices to hold it in place. As it heals, the bone tunnels fill in. This holds the new ligament in place. At the end of the surgery, your surgeon will close your cuts with sutures (stitches) and cover the area with a dressing. You may be able to view pictures after the procedure of what the doctor saw and what was done during the surgery.

Lead poisoning in kids samer kareem 3,231 Views • 3 years ago

Lead poisoning symptoms in children Signs and symptoms of lead poisoning in children include: Developmental delay Learning difficulties Irritability Loss of appetite Weight loss Sluggishness and fatigue Abdominal pain Vomiting Constipation Hearing loss Seizures Eating things, such as paint chips, that aren't food (pica) Lead poisoning symptoms in newborns Babies exposed to lead before birth might: Be born prematurely Have lower birth weight Have slowed growth Lead poisoning symptoms in adults Although children are primarily at risk, lead poisoning is also dangerous for adults. Signs and symptoms in adults might include: High blood pressure Joint and muscle pain Difficulties with memory or concentration Headache Abdominal pain Mood disorders Reduced sperm count and abnormal sperm Miscarriage, stillbirth or premature birth in pregnant women Causes Lead is a metal that occurs naturally in the earth's crust, but human activity — mining, burning fossil fuels and manufacturing — has caused it to become more widespread. Lead was also once used in paint and gasoline and is still used in batteries, solder, pipes, pottery, roofing materials and some cosmetics. Lead in paint Lead-based paints for homes, children's toys and household furniture have been banned in the United States since 1978. But lead-based paint is still on walls and woodwork in many older homes and apartments. Most lead poisoning in children results from eating chips of deteriorating lead-based paint. Water pipes and imported canned goods Lead pipes, brass plumbing fixtures and copper pipes soldered with lead can release lead particles into tap water. Lead solder in food cans, banned in the United States, is still used in some countries. Other sources of lead exposure Lead sometimes can also be found in: Soil. Lead particles from leaded gasoline or paint settle on soil and can last years. Lead-contaminated soil is still a major problem around highways and in some urban settings. Some soil close to walls of older houses contains lead. Household dust. Household dust can contain lead from lead paint chips or from contaminated soil brought in from outside. Pottery. Glazes found on some ceramics, china and porcelain can contain lead that can leach into food served or stored in the pottery. Toys. Lead is sometimes found in toys and other products produced abroad. Cosmetics. Tiro, an eye cosmetic from Nigeria, has been linked to lead poisoning. Herbal or folk remedies. Lead poisoning has been linked to greta and azarcon, traditional Hispanic medicines, as well as some from India, China and other countries. Mexican candy. Tamarind, an ingredient used in some candies made in Mexico, might contain lead. Lead bullets. Time spent at firing ranges can lead to exposure. Occupations. People are exposed to lead and can bring it home on their clothes when they work in auto repair, mining, pipe fitting, battery manufacturing, painting, construction and certain other fields

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.
