Has your dentist or endodontist told you that you need root canal treatment? If so, you're not alone. Millions of teeth are treated and saved each year with root canal, or endodontic, treatment. Remember, root canal treatment doesn't cause pain, it relieves it. Watch our videos below to learn more! Inside the tooth, under the white enamel and a hard layer called the dentin, is a soft tissue called the pulp. The pulp contains blood vessels, nerves and connective tissue, and helps to grow the root of your tooth during development. In a fully developed tooth, the tooth can survive without the pulp because the tooth continues to be nourished by the tissues surrounding it.
This 3D medical animation contains the discharge instructions for removal of a Foley catheter from a man. The step-by-step procedures for emptying the Foley bag and removing the Foley catheter are shown. Symptoms requiring a follow-up call to the surgeon are listed.
The Distal Femoral Osteotomy System utilizes the same principles of design featured in the Tibial Osteotomy System. Specifically designed femoral osteotomy plates take into account the anatomical differences between the distal femur and proximal tibia.

The needle should pass through the tissue at a perpendiculaPlace the tips of the left-hand forceps on the underside of the tissue at the point where the needle will enter, and gently push the edge upward. With the right hand, bring the needle into contact with the tissue, and press downward. These movements create eversion. Pass the needle through. Do not grab the tissue with your left hand forceps since it will damage the intima. If needed, you can pick up adventitia or a nearby suture to help with exposure and eversion. r.The needle must pass through the other side at a perpendicular, too. Bring the tip of the needle to the place where you intend to bring it out on the other side. Put the tip of your left-hand forceps on the upper surface of the tissue at the intended exit point. Press down with the left-hand forceps and push up with the needle to give you the correct eversion. The width of the bite should be about three times the thickness of the needle. The bites on both sides must be equal, and the needle should cross exactly in a straight line (not diagonally). Pull the needle through the tissue following the curve of the needle
A chronic cough is a cough that lasts eight weeks or longer in adults, or four weeks in children. A chronic cough is more than just an annoyance. A chronic cough can interrupt your sleep and leave you feeling exhausted. Severe cases of chronic cough can cause vomiting, lightheadedness and even rib fractures. While it can sometimes be difficult to pinpoint the problem that's triggering a chronic cough, the most common causes are tobacco use, postnasal drip, asthma and acid reflux. Fortunately, chronic cough typically disappears once the underlying problem is treated.
Rare condition disorder known as Diprosopus, also known as craniofacial duplication. Diprosopus is a congenital defect also known as craniofacial duplication. The exact description of diprosopus refers to a fetus with a single trunk, normal limbs, and facial features that are duplicated to a certain degree. A less severe instance is when the fetus has a duplicated nose and the eyes are spaced far apart. In the most extreme instances, the entire face is duplicated, hence the name diprosopus, which is Greek for two-faced. Fetuses with diprosopus often also lack brains (anencephaly), have neural tube defects, or heart malformations. In some cases, if the brain is formed, it may have duplicated structures. Most infants with diprosopus are stillborn and there are fewer than fifty cases documented since 1864.
When the hematocrit rises to 60 or 70%, which it often does in polycythemia, the blood viscosity can become as great as 10 times that of water, and its flow through blood vessels is greatly retarded because of increased resistance to flow. This will lead to decreased oxygen delivery.
