TPE removes large-molecular-weight substances such as harmful antibodies from the plasma. It is usually carried out using an automated blood cell separator to ensure fluid balance and maintain a normal plasma volume. This may require the insertion of a femoral or jugular line to allow adequate blood flow. Typically, 30–40 mL/kg of plasma (1–1.5 plasma volumes) are removed at each procedure and replaced with isotonic 4.5 or 5.0% human albumin solution (some services substitute 25–50% of replacement volume with 0.9% saline). Exchange with fresh frozen plasma (FFP) is reserved for the replacement of ADAMTS13 in thrombotic thrombocytopenic purpura (see below) or to replace clotting factors. A one plasma volume exchange removes about 66% of an intravascular constituent and a two plasma volume exchange approximately 85%. TPE is normally combined with disease modifying treatment, such as immunosuppressive drugs, for the underlying condition.
Cirrhosis is a late stage of scarring (fibrosis) of the liver caused by many forms of liver diseases and conditions, such as hepatitis and chronic alcoholism. The liver carries out several necessary functions, including detoxifying harmful substances in your body, cleaning your blood and making vital nutrients. Cirrhosis occurs in response to damage to your liver. Each time your liver is injured, it tries to repair itself. In the process, scar tissue forms. As cirrhosis progresses, more and more scar tissue forms, making it difficult for the liver to function. Decompensated cirrhosis is the term used to describe the development of specific complications resulting from the changes brought on by cirrhosis. Decompensated cirrhosis is life-threatening. The liver damage done by cirrhosis generally can't be undone. But if liver cirrhosis is diagnosed early and the cause is treated, further damage can be limited and, rarely, reversed.
To identify an UTI, keep an eye out for the following symptoms: A burning feeling when you urinate. A frequent or intense urge to urinate, even though little comes out when you do. Pain or pressure in your back or lower abdomen. Cloudy, dark, bloody, or strange-smelling urine. Feeling tired or shaky.
Cardiac cath is performed to find out if you have disease of the heart muscle, valves or coronary (heart) arteries. During the procedure, the pressure and blood flow in your heart can be measured. Coronary angiography is done during cardiac catheterization.
A heart attack is a medical emergency. A heart attack usually occurs when a blood clot blocks blood flow to the heart. Without blood, tissue loses oxygen and dies. Symptoms include tightness or pain in the chest, neck, back, or arms, as well as fatigue, lightheadedness, abnormal heartbeat, and anxiety. Women are more likely to have atypical symptoms than men. Treatment ranges from lifestyle changes and cardiac rehabilitation to medications, stents, and bypass surgery.
The rotator cuff is a group of muscles and tendons that surround the shoulder joint, keeping the head of your upper arm bone firmly within the shallow socket of the shoulder. A rotator cuff injury can cause a dull ache in the shoulder, which often worsens when you try to sleep on the involved side. Rotator cuff injuries occur most often in people who repeatedly perform overhead motions in their jobs or sports. Examples include painters, carpenters, and people who play baseball or tennis. The risk of rotator cuff injury also increases with age. Many people recover from rotator cuff disease with physical therapy exercises that improve flexibility and strength of the muscles surrounding the shoulder joint. Sometimes, rotator cuff tears may occur as a result of a single injury. In those circumstances, medical care should be provided as soon as possible. Extensive rotator cuff tears may require surgical repair, transfer of alternative tendons or joint replacement.
Genes are the building blocks of heredity. They are passed from parent to child. They hold DNA, the instructions for making proteins. Proteins do most of the work in cells. They move molecules from one place to another, build structures, break down toxins, and do many other maintenance jobs. Sometimes there is a mutation, a change in a gene or genes. The mutation changes the gene's instructions for making a protein, so the protein does not work properly or is missing entirely. This can cause a medical condition called a genetic disorder. You can inherit a gene mutation from one or both parents. A mutation can also happen during your lifetime.
Learn about Bicuspid Aortic Valves in this presentation. Bicuspid Aortic Valves are present in about 2% of the population and are the most common congenital disorder. Find out more about a Bicuspid Aortic Valve by visiting the following link:
TAA is performed either under general anesthetic or nerve block. A tourniquet is used at the time of surgery to control bleeding and improve visualization during the surgery. The ankle is approached from the front or the side depending on the type of implant being used. Bone is then cut, allowing for placement of the metal and plastic components that re-create the ankle joint. Sometimes the patient will have a tight calf muscle or tight Achilles tendon that needs to be lengthened to improve range of motion of the ankle. The wounds are then closed using stitches or staples, and a splint is applied. A period of non-weightbearing in either a cast or cast boot is necessary to allow the implants to heal in place.
The pituitary is a small gland found inside the skull just below the brain and above the nasal passages, which are above the fleshy back part of the roof of the mouth (known as the soft palate). The pituitary sits in a tiny bony space called the sella turcica. The nerves that connect the eyes to the brain, called the optic nerves, pass close by it.
Trichinosis (trik-ih-NO-sis), sometimes called trichinellosis (trik-ih-nuh-LOW-sis), is a type of roundworm infection. Roundworm parasites use a host body to live and reproduce. Occurring primarily among meat-eating animals (carnivores) — especially bears, foxes and walruses — the infection is acquired by eating roundworm larvae in raw or undercooked meat. When humans eat undercooked meat containing trichinella larvae, the larvae mature into adult worms in the intestine over several weeks. The adult worms then produce larvae that travel through various tissues, including muscle. Trichinosis is most widespread in rural areas throughout the world. Trichinosis can be treated with medication, though it's not always necessary. It's also easy to prevent.
Hemothorax is the presence of blood in the pleural space. The source of blood may be the chest wall, lung parenchyma, heart, or great vessels. Although some authors state that a hematocrit value of at least 50% is necessary to differentiate a hemothorax from a bloody pleural effusion, most do not agree on any specific distinction. Hemothorax is usually a consequence of blunt or penetrating trauma. Much less commonly, it may be a complication of disease, may be iatrogenically induced, [1] or may develop spontaneously. [2] Prompt identification and treatment of traumatic hemothorax is an essential part of the care of the injured patient. The upright chest radiograph is the ideal primary diagnostic study in the evaluation of hemothorax (see Workup). In cases of hemothorax unrelated to trauma, a careful investigation for the underlying source must be performed while treatment is provided.
