Bilateral Lower Extremity Inflammatory Lymphedema
Bilateral lower extremity inflammatory lymphedema (BLEIL) is a distinct clinical entity characterized by acute lymphedema in both ankles and lower legs after being exposed to prolonged standing, such as during military basic training. Presentation Patients present with an acute onset of swelling, pain, erythema, prominent tenderness, warmness and limited range of motion in both ankles. Lower legs and heels may also be involved, however the distal parts of feet and toes are usually spared. Patients may also experience high-graded fever, pitting edema and hypotension. The clinical presentation usually resembles cellulitis, however bilateral involvement is a differentiating feature. Cause The pathophysiology is not yet well understood. Leukocytoclastic vasculitis is proposed to be the underlying cause resulting in reactive lymphedema. Prolonged standing with full knee extension and minimal movement for a prolonged period of time is postulated to induce a temporary failure in p ...

Military Medicine
The term military medicine has a number of potential connotations. It may mean: *A medical specialty, specifically a branch of occupational medicine attending to the medical risks and needs (both preventive and interventional) of soldiers, sailors and other service members. This disparate arena has historically involved the prevention and treatment of infectious diseases (especially tropical diseases), and, in the 20th Century, the ergonomics and health effects of operating military-specific machines and equipment such as submarines, tanks, helicopters and airplanes. Undersea and aviation medicine can be understood as subspecialties of military medicine, or in any case originated as such. Few countries certify or recognize "military medicine" as a formal speciality or subspeciality in its own right. * The planning and practice of the surgical management of mass battlefield casualties and the logistical and administrative considerations of establishing and operating com ...

Erythrocyte Sedimentation Rate
The erythrocyte sedimentation rate (ESR or sed rate) is the rate at which red blood cells in anticoagulated whole blood descend in a standardized tube over a period of one hour. It is a common hematology test, and is a non-specific measure of inflammation. To perform the test, anticoagulated blood is traditionally placed in an upright tube, known as a Westergren tube, and the distance which the red blood cells fall is measured and reported in millimetre at the end of one hour. Since the introduction of automated analyzers into the clinical laboratory, the ESR test has been automatically performed. The ESR is governed by the balance between pro-sedimentation factors, mainly fibrinogen, and those factors resisting sedimentation, namely the negative charge of the erythrocytes (zeta potential). When an inflammatory process is present, the high proportion of fibrinogen in the blood causes red blood cells to stick to each other. The red cells form stacks called ''rouleaux'' which ...

Diseases Of Veins, Lymphatic Vessels And Lymph Nodes
A disease is a particular abnormal condition that negatively affects the structure or function of all or part of an organism, and that is not immediately due to any external injury. Diseases are often known to be medical conditions that are associated with specific signs and symptoms. A disease may be caused by external factors such as pathogens or by internal dysfunctions. For example, internal dysfunctions of the immune system can produce a variety of different diseases, including various forms of immunodeficiency, hypersensitivity, allergies and autoimmune disorders. In humans, ''disease'' is often used more broadly to refer to any condition that causes pain, dysfunction, distress, social problems, or death to the person affected, or similar problems for those in contact with the person. In this broader sense, it sometimes includes injuries, disabilities, disorders, syndromes, infections, isolated symptoms, deviant behaviors, and atypical variations of structure and f ...

Lymphatic Vessel Diseases
Lymph (from Latin, , meaning "water") is the fluid that flows through the lymphatic system, a system composed of lymph vessels (channels) and intervening lymph nodes whose function, like the venous system, is to return fluid from the tissues to be recirculated. At the origin of the fluid-return process, interstitial fluid—the fluid between the cells in all body tissues—enters the lymph capillaries. This lymphatic fluid is then transported via progressively larger lymphatic vessels through lymph nodes, where substances are removed by tissue lymphocytes and circulating lymphocytes are added to the fluid, before emptying ultimately into the right or the left subclavian vein, where it mixes with central venous blood. Because it is derived from interstitial fluid, with which blood and surrounding cells continually exchange substances, lymph undergoes continual change in composition. It is generally similar to blood plasma, which is the fluid component of blood. Lymph returns prote ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Recruit Training
Military recruit training, commonly known as basic training or boot camp, refers to the initial instruction of new military personnel. It is a physically and psychologically intensive process, which resocializes its subjects for the unique demands of military employment. Major characteristics Initial military training is an intensive residential programme commonly lasting several weeks or months, which aims to induct newly recruited military personnel into the social norms and essential tasks of the armed forces. Common features include foot drill, inspections, physical training, weapons training, and a graduation parade. The training process resocializes recruits to the demands made of them by military life. Psychological conditioning techniques are used to shape attitudes and behaviours, so that recruits will obey all orders, face mortal danger, and kill their opponents in battle. According to an expert in United States military training methods, Dave Grossman, recruit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compression Stockings
Compression stockings (Flight Socks, Support Bandage) are a specialized hosiery designed to help prevent the occurrence of, and guard against further progression of, venous disorders such as edema, phlebitis and thrombosis. Compression stockings are elastic compression garments worn around the leg, compressing the limb. This reduces the diameter of distended veins and increases venous blood flow velocity and valve effectiveness. Compression therapy helps decrease venous pressure, prevents venous stasis and impairments of venous walls, and relieves heavy and aching legs. Knee-high compression stockings are used not only to help increase circulation, but also to help prevent the formation of blood clots in the lower legs. They also aid in the treatment of ulcers of the lower legs. Unlike traditional dress or athletic stockings and socks, compression stockings use stronger elastics to create significant pressure on the legs, ankles and feet. Compression stockings are tightest at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malleolus
A malleolus is the bony prominence on each side of the human ankle. Each leg is supported by two bones, the tibia on the inner side (medial) of the leg and the fibula on the outer side (lateral) of the leg. The medial malleolus is the prominence on the inner side of the ankle, formed by the lower end of the tibia. The lateral malleolus is the prominence on the outer side of the ankle, formed by the lower end of the fibula. The word ''malleolus'' (), plural ''malleoli'' (), comes from Latin and means "small hammer". (It is cognate with ''mallet''.) Medial malleolus The medial malleolus is found at the foot end of the tibia. The medial surface of the lower extremity of tibia is prolonged downward to form a strong pyramidal process, flattened from without inward - the medial malleolus. * The ''medial surface'' of this process is convex and subcutaneous. * The ''lateral'' or ''articular surface'' is smooth and slightly concave, and articulates with the talus. * The ''anterior bo ...

C-reactive Protein
C-reactive protein (CRP) is an annular (ring-shaped) pentameric protein found in blood plasma, whose circulating concentrations rise in response to inflammation. It is an acute-phase protein of hepatic origin that increases following interleukin-6 secretion by macrophages and T cells. Its physiological role is to bind to lysophosphatidylcholine expressed on the surface of dead or dying cells (and some types of bacteria) in order to activate the complement system via C1q. CRP is synthesized by the liver in response to factors released by macrophages and fat cells (adipocytes). It is a member of the pentraxin family of proteins. It is not related to C-peptide (insulin) or protein C (blood coagulation). C-reactive protein was the first pattern recognition receptor (PRR) to be identified. History Discovered by Tillett and Francis in 1930, it was initially thought that CRP might be a pathogenic secretion since it was elevated in a variety of illnesses, including cancer. The later ...

White Blood Cells
White blood cells, also called leukocytes or leucocytes, are the cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders. All white blood cells are produced and derived from multipotent cells in the bone marrow known as hematopoietic stem cells. Leukocytes are found throughout the body, including the blood and lymphatic system. All white blood cells have nuclei, which distinguishes them from the other blood cells, the anucleated red blood cells (RBCs) and platelets. The different white blood cells are usually classified by cell lineage (myeloid cells or lymphoid cells). White blood cells are part of the body's immune system. They help the body fight infection and other diseases. Types of white blood cells are granulocytes (neutrophils, eosinophils, and basophils), and agranulocytes (monocytes, and lymphocytes (T cells and B cells)). Myeloid cells (myelocytes) include neutrophils, eosinophils, mast cells, bas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cellulitis
Cellulitis is usually a bacterial infection involving the inner layers of the skin. It specifically affects the dermis and subcutaneous fat. Signs and symptoms include an area of redness which increases in size over a few days. The borders of the area of redness are generally not sharp and the skin may be swollen. While the redness often turns white when pressure is applied, this is not always the case. The area of infection is usually painful. Lymphatic vessels may occasionally be involved, and the person may have a fever and feel tired. The legs and face are the most common sites involved, although cellulitis can occur on any part of the body. The leg is typically affected following a break in the skin. Other risk factors include obesity, leg swelling, and old age. For facial infections, a break in the skin beforehand is not usually the case. The bacteria most commonly involved are streptococci and '' Staphylococcus aureus''. In contrast to cellulitis, erysipelas is a bacte ...
