Lymphedema Distichiasis
Lymphedema, also known as lymphoedema and lymphatic edema, is a condition of localized edema, swelling caused by a compromised lymphatic system. The lymphatic system functions as a critical portion of the body's immune system and returns interstitial fluid to the bloodstream. Lymphedema is most frequently a complication of cancer treatment or parasitic infections, but it can also be seen in a number of genetic disorders. Though incurable and progressive, a number of treatments may improve symptoms. Tissues with lymphedema are at high risk of infection because the lymphatic system has been compromised. While there is no cure, treatment may improve outcomes. This commonly include compression therapy, good skin care, exercise, and manual lymphatic drainage (MLD), which together are known as combined decongestive therapy. Diuretics are not useful. Signs and symptoms The most common manifestation of lymphedema is soft tissue swelling, edema. As the disorder progresses, worsening ed ...

Vascular Medicine
Angiology (from Greek , ''angeīon'', "vessel"; and , '' -logia'') is the medical specialty dedicated to studying the circulatory system and of the lymphatic system, i.e., arteries, veins and lymphatic vessels. In the UK, this field is more often termed ''angiology'', and in the United States the term vascular medicine is more frequent. The field of vascular medicine (angiology) is the field that deals with preventing, diagnosing and treating vascular and blood vessel related diseases. Overview Arterial diseases include the aorta (aneurysms/dissection) and arteries supplying the legs, hands, kidneys, brain, intestines. It also covers arterial thrombosis and embolism; vasculitides; and vasospastic disorders. Naturally, it deals with preventing cardiovascular diseases such as heart attack and stroke. Venous diseases include venous thrombosis, chronic venous insufficiency, and varicose veins. Lymphatic diseases include primary and secondary forms of lymphedema. It also invo ...

Manual Lymphatic Drainage
Manual lymphatic drainage (MLD) is a type of massage based on the hypothesis that it will encourage the natural drainage of the lymph, which carries waste products away from the tissues back toward the heart. The lymph system depends on intrinsic contractions of the smooth muscle cells in the walls of lymph vessels (peristalsis) and the movement of skeletal muscles to propel lymph through the vessels to lymph nodes and then to the lymph ducts, which return lymph to the cardiovascular system. Manual lymph drainage uses a specific amount of pressure (less than 9oz per square inch or about 4kPa), and rhythmic circular movements to stimulate lymph flow. Medical use Studies show mixed results regarding the efficacy of the method in treating lymphedema, and further studies are needed. A 2013 systematic review of manual lymphatic drainage with regard to breast cancer–related lymphedema found no clear support for the effectiveness of the intervention in either preventing limb edema in at ...

Retiform Hemangioendothelioma
Hemangioendotheliomas are a family of vascular neoplasms of intermediate malignancy. Signs and symptoms They have been described as masses that fall between a hemangioma and angiosarcoma. They are vascular tumors that commonly present with an enlarging mass and most commonly involve the lungs, liver, and musculoskeletal system, although many other body sites have been reported, including the head and neck, intestines, lymph nodes, pleura, retroperitoneum, heel, stomach. Cause Possibly Bartonella spp bacteraemia Diagnosis Classification Hemangioendotheliomas may be classified as: * ''Epithelioid hemangioendothelioma'' is an uncommon vascular tumor of intermediate malignancy that was first described by Steven Billings, Andrew Folpe, and Sharon Weiss in 2003. These tumors are so named because their histologic appearance resembles a proliferation of epithelioid cells, with polygonal shape and eosinophilic cytoplasm. * ''Composite hemangioendothelioma'' is a low-grade angiosarcoma ty ...

Stewart–Treves Syndrome
Stewart–Treves syndrome refers to a lymphangiosarcoma, a rare disorder marked by the presence of an angiosarcoma (a malignant tumor of blood or lymph vessels) in a person with chronic (long-term) lymphedema. Although it most commonly refers to malignancies associated with chronic lymphedema resulting from mastectomy and/or radiotherapy for breast cancer, it may also describe lymphangiosarcomas that result from congenital and other causes of chronic secondary lymphedema. Lymphangiosarcoma arising from cancer-related lymphedema has become much less common with better surgical techniques, radiation therapy, and conservative treatment. The prognosis, even with wide surgical excision and subsequent radiotherapy, is poor. Cause Common risk factors that may lead to the development of lymphangiosarcoma include lymphatic blockage, radiotherapy, mastectomy, cardiovascular diseases, and hypertension. The sarcoma first appears as a bruise mark, a purplish discoloration or a tender skin nodul ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Lymphangiosarcoma
Lymphangiosarcoma is a rare cancer which occurs in long-standing cases of primary or secondary lymphedema. It involves either the upper or lower lymphedematous extremities but is most common in upper extremities. Although its name implies lymphatic origin, it is believed to arise from endothelial cells and may be more accurately referred to as angiosarcoma. Signs and symptoms Lymphangiosarcoma may present as a purple discoloration or a tender skin nodule in the extremity, typically on the anterior surface. It progresses to an ulcer with crusting to an extensive necrotic focus involving the skin and subcutaneous tissue. It metastasizes quickly. Causes It was previously a relatively common complication of the massive lymphedema of the arm which followed removal of axillary (arm pit) lymph nodes and lymphatic channels as part of the classical Halstedian radical mastectomy, as a treatment for breast cancer. The classical radical mastectomy was abandoned in most areas of the world in ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Lymphadenitis
Lymphadenopathy or adenopathy is a disease of the lymph nodes, in which they are abnormal in size or consistency. Lymphadenopathy of an inflammatory type (the most common type) is lymphadenitis, producing swollen or enlarged lymph nodes. In clinical practice, the distinction between lymphadenopathy and lymphadenitis is rarely made and the words are usually treated as synonymous. Inflammation of the lymphatic vessels is known as lymphangitis. Infectious lymphadenitis affecting lymph nodes in the neck is often called scrofula. Lymphadenopathy is a common and nonspecific sign. Common causes include infections (from minor causes such as the common cold and post-vaccination swelling to serious ones such as HIV/AIDS), autoimmune diseases, and cancer. Lymphadenopathy is frequently idiopathic and self-limiting. Causes Lymph node enlargement is recognized as a common sign of infectious, autoimmune, or malignant disease. Examples may include: * Reactive: acute infection (''e.g.,'' ba ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Lymphangitis
Lymphangitis is an inflammation or an infection of the lymphatic channels that occurs as a result of infection at a site distal to the channel. The most common cause of lymphangitis in humans is ''Streptococcus pyogenes'' (Group A strep), hemolytic streptococci, and in some cases, mononucleosis, cytomegalovirus, tuberculosis, syphilis, and the fungus ''Sporothrix schenckii''. Lymphangitis is sometimes mistakenly called "blood poisoning". In reality, "blood poisoning" is synonymous with ''sepsis''. Lymphatic vessels are smaller than capillaries and tiny venules and are ubiquitous in the body. These vessels are fitted with valves to direct flow in only one direction. Fluid diffusing through the thin-walled small capillaries should be collected and the lymphatic system does just that: a fluid rich in protein, minerals, nutrients, and other substances useful for tissue growth. As well as essential nutrients, the lymphatic system can also transport or carry cancer cells, defective or d ...

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 ...

Infections
An infection is the invasion of tissue (biology), tissues by pathogens, their multiplication, and the reaction of host (biology), host tissues to the infectious agent and the toxins they produce. An infectious disease, also known as a transmissible disease or communicable disease, is an Disease#Terminology, illness resulting from an infection. Infections can be caused by a wide range of pathogens, most prominently pathogenic bacteria, bacteria and viruses. Hosts can fight infections using their immune system. Mammalian hosts react to infections with an Innate immune system, innate response, often involving inflammation, followed by an Adaptive immune system, adaptive response. Specific pharmaceutical drug, medications used to treat infections include antibiotics, antiviral drug, antivirals, antifungal medication, antifungals, Antiprotozoal agent, antiprotozoals, and antihelminthics. Infectious diseases resulted in 9.2 million deaths in 2013 (about 17% of all deaths). The branch ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Erysipelas
Erysipelas () is a relatively common bacterial infection of the superficial layer of the skin ( upper dermis), extending to the superficial lymphatic vessels within the skin, characterized by a raised, well-defined, tender, bright red rash, typically on the face or legs, but which can occur anywhere on the skin. It is a form of cellulitis and is potentially serious. Erysipelas is usually caused by the bacteria ''Streptococcus pyogenes'', also known as ''group A β-hemolytic streptococci'', which enters the body through a break in the skin, such as a scratch or an insect bite. It is more superficial than cellulitis, and is typically more raised and demarcated. The term comes from the Greek ἐρυσίπελας (''erysípelas''), meaning "red skin". In animals, erysipelas is a disease caused by infection with the bacterium ''Erysipelothrix rhusiopathiae''. The disease caused in animals is called Diamond Skin Disease, which occurs especially in pigs. Heart valves and skin are a ...

Ulcer (dermatology)
An ulcer is a sore on the skin or a mucous membrane, accompanied by the disintegration of tissue. Ulcers can result in complete loss of the epidermis and often portions of the dermis and even subcutaneous fat. Ulcers are most common on the skin of the lower extremities and in the gastrointestinal tract. An ulcer that appears on the skin is often visible as an inflamed tissue with an area of reddened skin. A skin ulcer is often visible in the event of exposure to heat or cold, irritation, or a problem with blood circulation. They can also be caused due to a lack of mobility, which causes prolonged pressure on the tissues. This stress in the blood circulation is transformed to a skin ulcer, commonly known as bedsores or decubitus ulcers. Ulcers often become infected, and pus forms. Signs and symptoms Skin ulcers appear as open craters, often round, with layers of skin that have eroded. The skin around the ulcer may be red, swollen, and tender. Patients may feel pain on the skin ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
