Triglycerides are the most common form of fat found in our bodies. The word triglyceride describes this fat's chemical structure. Its chemical backbone is made up of glyceride (a carbon, oxygen, and hydrogen molecule) with three (tri) attached fatty acid chains. It is also the most common form of fat in vegetable oil and animal fat. Triglycerides are very important as they serve as one of our main energy reserves. They have more than twice the energy as an equivalent amount of carbohydrate or protein. Triglycerides can be absorbed from food through the intestine. Fat cannot freely circulate in the blood, and when we absorb triglycerides or fatty-acids in food, they are repackaged as triglycerides in a fat-protein transporter called a chylomicron. Our body can also make its own triglycerides when we eat more energy than we use, and the energy consumed does not necessarily have to come from fat. The liver can create a fat-protein ...
Neuropathy - distal median nerve
Pain in the wrist or hand that wakes you up at night
May be severe Pain may be felt in other areas, for example in the upper arm (this is called referred pain)
Sensation changes in the thumb and pointer (index), middle, and part of the ring fingers, such as:
Weakness of the hand that causes you to:
Drop things Have difficulty grasping objects
Signs and tests
Your doctor will examine your wrist and ask questions about your medical history. The examination may show decreased sensation in the thumb side of the hand. This is called the "radial" side. There may be weakness of the thumb and difficulty using it to pinch.
Tests that reveal distal median nerve dysfunction may include:
Nerve conduction tests
Tests are ...
More and more studies show that controlling patients' pain and getting them moving after a total knee replacement (TKR) gives the best results. Doctors are looking for ways to do this. Managing patient's pain in the first 24 hours after surgery seems to be an important key. Better pain control is gained by giving the patient general anesthesia along with a local nerve block at the time of surgery. One of the nerves often blocked is the femoral nerve, which forms from nerve roots in the low back and runs down the front of the thigh. Blocks are also done to the sciatic nerve. The sciatic nerve is a major nerve that goes down the back of the thigh to the lower leg and foot. This study compared a femoral nerve block alone to a "double block" of the femoral nerve and the sciatic nerve. Pain levels and amount of opiate used were measured every four hours for the first 24 hours. The authors found that patients receiving the double blocks used less pain medication after TKR than those getting ju...
