lymeská nemoc

An infectious disease caused by a spirochete, BORRELIA BURGDORFERI, which is transmitted chiefly by Ixodes dammini (see IXODES) and pacificus ticks in the United States and Ixodes ricinis (see IXODES) in Europe. It is a disease with early and late cutaneous manifestations plus involvement of the nervous system, heart, eye, and joints in variable combinations. The disease was formerly known as Lyme arthritis and first discovered at Old Lyme, Connecticut.
MSH

recurrent multisystemic infectious disease caused by a spirochete, Borrelia burgdorferi, which is transmitted chiefly by Ixodes ticks; it is a disease with early and late cutaneous manifestations plus involvement of the nervous system, heart, eye, and joints in variable combinations.
CSP

Lyme disease is a bacterial infection you get from the bite of an infected tick. The first symptom is usually a rash, which may look like a bull`s eye. As the infection spreads, you may have

  • A fever
  • A headache
  • Muscle and joint aches
  • A stiff neck
  • Fatigue

Lyme disease can be hard to diagnose because you may not have noticed a tick bite. Also, many of its symptoms are like those of the flu and other diseases. In the early stages, your health care provider will look at your symptoms and medical history, to figure out whether you have Lyme disease. Lab tests may help at this stage, but may not always give a clear answer. In the later stages of the disease, a different lab test can confirm whether you have it.

Antibiotics can cure most cases of Lyme disease. The sooner treatment begins, the quicker and more complete the recovery.

After treatment, some patients may still have muscle or joint aches and nervous system symptoms. This is called post-Lyme disease syndrome (PLDS). Long-term antibiotics have not been shown to help with PLDS. However, there are ways to help with the symptoms of PLDS, and most patients do get better with time.

lymfatické nemoci

Diseases of LYMPH; LYMPH NODES; or LYMPHATIC VESSELS.
MSH

condition in which there is a deviation from or interruption of the normal structure or function of the lymph or lymph vessels.
CSP

The lymphatic system is a network of tissues and organs. It is made up mainly of lymph vessels, lymph nodes and lymph. Lymph vessels, which are different from blood vessels, carry fluid called lymph throughout your body. Lymph contains white blood cells that defend you against germs. Throughout the vessels are lymph nodes. Along with your spleen, these nodes are where white blood cells fight infection. Your bone marrow and thymus produce the cells in lymph. They are part of the system, too.

The lymphatic system clears away infection and keeps your body fluids in balance. If it`s not working properly, fluid builds in your tissues and causes swelling, called lymphedema. Other lymphatic system problems can include infections, blockage, and cancer.

lymfedém

edema due to obstruction of lymph vessels or disorders of the lymph nodes.
CSP

A condition in which extra lymph fluid builds up in tissues and causes swelling. It may occur in an arm or leg if lymph vessels are blocked, damaged, or removed by surgery.
NCI

The lymphatic system is a network of tissues and organs. It is made up mainly of lymph vessels, lymph nodes and lymph. Lymph vessels, which are different from blood vessels, carry fluid called lymph throughout your body.

The lymphatic system collects excess fluid and proteins from body tissues and carries them back to the bloodstream. Edema, or swelling, may happen when there is an increase in the amount of fluid or because of a blockage in the lymphatic system. The accumulation of lymph is called lymphedema.

Causes of lymphedema include

  • Infection
  • Cancer
  • Scar tissue from radiation therapy or surgical removal of lymph nodes
  • Inherited conditions in which lymph nodes or vessels are absent or abnormal

Treatment includes physical methods, such as compression stockings, and medicines.
