Georg Perthes
Georg Clemens Perthes (17 January 1869 – 3 January 1927) was a German surgeon and X-ray diagnostic pioneer. Biography Perthes was born in Moers, Germany. In 1891 he received his medical doctorate from the University of Bonn, and later was a surgeon in Bonn and Leipzig where he worked with Friedrich Trendelenburg (1844–1924). In 1910 he succeeded Paul von Bruns (1846–1916) as head of the surgical clinic at Tübingen. In 1900–01 he was a military surgeon at the German colonial seaport of Tsingtao (today known as Qingdao, China). Perthes' primary area of research involved radiological treatment and therapy. He pioneered the use of radiology for the treatment of warts, skin cancer and breast carcinomas. Today he is best known for a child illness named Perthes' disease, also known as Legg–Calvé–Perthes syndrome, a disease causing avascular necrosis of the hip joint. Perthes took the first X-rays of a patient with this syndrome in 1898; however, his findings weren't publ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carcinoma
Carcinoma is a malignancy that develops from epithelial cells. Specifically, a carcinoma is a cancer that begins in a tissue that lines the inner or outer surfaces of the body, and that arises from cells originating in the endodermal, mesodermal or ectodermal germ layer during embryogenesis. Carcinomas occur when the DNA of a cell is damaged or altered and the cell begins to grow uncontrollably and become malignant. It is from the el, καρκίνωμα, translit=karkinoma, lit=sore, ulcer, cancer (itself derived from meaning ''crab''). Classification As of 2004, no simple and comprehensive classification system has been devised and accepted within the scientific community. Traditionally, however, malignancies have generally been classified into various types using a combination of criteria, including: The cell type from which they start; specifically: * Epithelial cells ⇨ carcinoma * Non-hematopoietic mesenchymal cells ⇨ sarcoma * Hematopoietic cells ** Bone mar ...

Epithelial Tissue
Epithelium or epithelial tissue is one of the four basic types of animal tissue, along with connective tissue, muscle tissue and nervous tissue. It is a thin, continuous, protective layer of compactly packed cells with a little intercellular matrix. Epithelial tissues line the outer surfaces of organs and blood vessels throughout the body, as well as the inner surfaces of cavities in many internal organs. An example is the epidermis, the outermost layer of the skin. There are three principal shapes of epithelial cell: squamous (scaly), columnar, and cuboidal. These can be arranged in a singular layer of cells as simple epithelium, either squamous, columnar, or cuboidal, or in layers of two or more cells deep as stratified (layered), or ''compound'', either squamous, columnar or cuboidal. In some tissues, a layer of columnar cells may appear to be stratified due to the placement of the nuclei. This sort of tissue is called pseudostratified. All glands are made up of epithe ...

Bernhard Von Langenbeck
Bernhard Rudolf Konrad von Langenbeck (9 November 181029 September 1887) was a German surgeon known as the developer of Langenbeck's amputation and founder of ''Langenbeck's Archives of Surgery''. Life He was born at Padingbüttel, and received his medical education at Göttingen, where one of his teachers was his uncle Konrad Johann Martin Langenbeck. He took his doctorate in 1835 with a thesis on the structure of the retina. After a visit to France and England, he returned to Göttingen as '' Privatdozent'', and in 1842 became Professor of Surgery and Director of the Friedrichs Hospital at Kiel. Six years later he succeeded Johann Friedrich Dieffenbach (1794–1847) as Director of the Clinical Institute for Surgery and Ophthalmology at the Charité in Berlin, and remained there till 1882, when failing health forced him to retire. Langenbeck was a bold and skillful surgeon, but preferred not to operate while other means afforded a prospect of success. He specialised in m ...

Stroke
A stroke is a disease, medical condition in which poor cerebral circulation, blood flow to the brain causes cell death. There are two main types of stroke: brain ischemia, ischemic, due to lack of blood flow, and intracranial hemorrhage, hemorrhagic, due to bleeding. Both cause parts of the brain to stop functioning properly. Signs and symptoms of a stroke may include an hemiplegia, inability to move or feel on one side of the body, receptive aphasia, problems understanding or expressive aphasia, speaking, dizziness, or Homonymous hemianopsia, loss of vision to one side. Signs and symptoms often appear soon after the stroke has occurred. If symptoms last less than one or two hours, the stroke is a transient ischemic attack (TIA), also called a mini-stroke. A subarachnoid hemorrhage, hemorrhagic stroke may also be associated with a thunderclap headache, severe headache. The symptoms of a stroke can be permanent. Long-term complications may include pneumonia and Urinary incontin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pierre Delbet
Pierre Delbet (15 November 1861 – 17 July 1957) was a French surgeon born in La Ferté-Gaucher. Biography In 1889 he received his medical doctorate, and in 1909 became a professor of clinical surgery in Paris. In 1921 he became a member of the ''Académie de Médecine''. Delbet is remembered for his advocacy of magnesium chloride. During World War I, Delbet was searching for a solution that could cleanse wounds but not damage tissue as traditional antiseptics did. In 1915 he found that magnesium chloride not only worked as an antiseptic but was also harmless to body tissue. Serendipitously, he discovered that when the magnesium chloride solution was taken orally or intravenously, it appeared to be a remedy for other ailments. Delbet also believed that magnesium was beneficial to the efficiency of white blood cells, of which he described in his treatise "''Politique Préventive du Cancer''". With Jean-François-Auguste Le Dentu (1841-1926) and others, he was co-publisher o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perthes Test
The Perthes test is a clinical test for assessing the patency of the deep femoral vein prior to varicose vein surgery. It is named after German surgeon Georg Perthes. The limb is elevated and an elastic bandage is applied firmly from the toes to the upper 1/3 of the thigh to obliterate the superficial veins only. With the bandage applied the patient is asked to walk for 5 minutes. If deep system is competent, the blood will go through and back to the heart. If the deep system is Blocked(has a thrombus), the patient will feel pain in the leg. This test is sometimes referred to as the Delbet-Mocquot test, named after French physicians Pierre Delbet Pierre Delbet (15 November 1861 – 17 July 1957) was a French surgeon born in La Ferté-Gaucher.

Varicose Vein
Varicose veins, also known as varicoses, are a medical condition in which superficial veins become enlarged and twisted. These veins typically develop in the legs, just under the skin. Varicose veins usually cause few symptoms. However, some individuals may experience fatigue or pain in the area. Complications can include bleeding or superficial thrombophlebitis. Varices in the scrotum are known as a varicocele, while those around the anus are known as hemorrhoids. Due to the various physical, social, and psychological effects of varicose veins, they can negatively affect one's quality of life. Varicose veins have no specific cause. Risk factors include obesity, lack of exercise, leg trauma, and family history of the condition. They also develop more commonly during pregnancy. Occasionally they result from chronic venous insufficiency. Underlying causes include weak or damaged valves in the veins. They are typically diagnosed by examination, including observation by ultrasou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Femoral Vein
In the human body, the femoral vein is a blood vessel that accompanies the femoral artery in the femoral sheath. It begins at the adductor hiatus (an opening in the adductor magnus muscle) as the continuation of the popliteal vein. It ends at the inferior margin of the inguinal ligament where it becomes the external iliac vein. The femoral vein bears valves which are mostly bicuspid and whose number is variable between individuals and often between left and right leg.

Hemostasis
In biology, hemostasis or haemostasis is a process to prevent and stop bleeding, meaning to keep blood within a damaged blood vessel (the opposite of hemostasis is hemorrhage). It is the first stage of wound healing. This involves coagulation, which changes blood from a liquid to a gel. Intact blood vessels are central to moderating blood's tendency to form clots. The endothelial cells of intact vessels prevent blood clotting with a heparin-like molecule and thrombomodulin, and prevent platelet aggregation with nitric oxide and prostacyclin. When endothelium of a blood vessel is damaged, the endothelial cells stop secretion of coagulation and aggregation inhibitors and instead secrete von Willebrand factor, which initiate the maintenance of hemostasis after injury. Hemostasis involves three major steps: * vasoconstriction * temporary blockage of a hole in a damaged blood vessel by a platelet plug * blood coagulation (formation of fibrin clots) These processes seal the inju ...

Empyema
An empyema () is a collection or gathering of pus within a naturally existing anatomical cavity. For example, pleural empyema is empyema of the pleural cavity. It must be differentiated from an abscess, which is a collection of pus in a newly formed cavity. The term is from Greek ἐμπύημα, "abscess". Classification Empyema occurs in: * the pleural cavity ( pleural empyema also known as pyothorax) * the thoracic cavity * the uterus ( pyometra) * the appendix (appendicitis) * the meninges In anatomy, the meninges (, ''singular:'' meninx ( or ), ) are the three membranes that envelop the brain and spinal cord. In mammals, the meninges are the dura mater, the arachnoid mater, and the pia mater. Cerebrospinal fluid is located in ...
