Classification of nerve injury was described by Seddon in 1943 and by Sunderland in 1951.Thomas KolbSolitary pulmonary noduleFull-body CT scan: A full-body scan is a scan of the patient's entire body as part of the diagnosis or treatment of illnesses. If computed tomography (CAT) scan technology is used, it is known as a full-body CT scan, though many medical imaging technologies can perform full-body scans.PneumoconiosisDag Vidar Kristoffersen: Dag Vidar Kristoffersen (born 1957 in Drammen) is a Norwegian football coach, best known for his time in Strømsgodset where he led the team to two silver medals in the Norwegian Football Cup and bronze medals in the Tippeligaen. Kristoffersen is a former football and bandy player, having represented Drafn in both sports.Knee pain: Knee pain is a common complaint for many people. There are several factors that can cause knee pain.Abdominal ultrasonographyCascade storage system: A cascade storage system is a high pressure gas cylinder system which is used for the refilling of smaller compressed gas cylinders or air cylinders. Each of the large cylinders is filled by a compressor, but the cascade system allows small cylinders to be filled without a compressor.Black Lung Benefits Act of 1973: The Black Lung Benefits Act (BLBA) is a U.S.AngiographyChalkstick fracture: Chalkstick fractures are fractures, typically of long bones, in which the fracture is transverse to the long axis of the bone, like a broken stick of chalk. A healthy long bone typically breaks like a hard woody stick as the collagen in the matrix adds remarkable flexibility to the mineral and the energy can run up and down the growth rings of bone.Bruce Goldsmith: Bruce Goldsmith is a British paraglider pilot and designer, and the 2007 Paragliding World Champion. He won the title at Manilla in Australia, flying an Airwave Magic FR3.Cervical fractureCaldwell's view: Caldwell's view (or Occipitofrontal view) is a radiographic view of skull, where X-ray plate is angled at 20° to orbitomeatal line. The rays pass from behind the head and are perpendicular to radiographic plate.Senior Emergency Department: The senior emergency department is a recent hospital innovation to build separate geriatric emergency rooms for older adults akin to pediatric emergency rooms designed for children. The trend comes in response to the nation's rapidly growing population of older adults and overcrowding of emergency departments.PneumothoraxGas pyelogram: A Gas pyelogram is a pyelogram in which the kidneys, renal pelvis and ureters are filled with gas, and have a radiolucent appearance. This gas is produced by some gas producing micro organisms which infect most upper parts of urinary system.Imaging phantom: Phantom}}Lung receptor: Lung receptors sense irritation or inflammation in the bronchi and alveoli.Image fusion: In computer vision, Multisensor Image fusion is the process of combining relevant information from two or more images into a single image.Haghighat, M.Ted Lapidus: Edmond "Ted" Lapidus (23 June 1929 – 29 December 2008) was a French fashion designer. He was born in Paris the son of a Russian-Jewish émigré tailor.Mandibular fractureCephalogram: A cephalogram is an X-ray of the craniofacial area. A cephalometric analysis could be used as means for measuring growth in children.Remitting seronegative symmetrical synovitis with pitting edema: Remitting seronegative symmetrical synovitis with pitting edema (abbreviated RS3PE or sometimes RS3PE) is a rare syndrome identified by symmetric polyarthritis, synovitis, acute pitting edema (swelling) of the back of the hands and/or feet, and a negative serum rheumatoid factor. If no underlying disorder can be identified (idiopathic RS3PE), this entity has an excellent prognosis and responds well to treatment.Joint dislocationBarium sulfate suspension: Barium sulfate suspension is barium sulfate powder turned into a liquid form by suspending it in a quick-flowing drink to aid in CT scans of the gastrointestinal region.Auscultation: Auscultation (based on the Latin verb auscultare "to listen") is listening to the internal sounds of the body, usually using a stethoscope. Auscultation is performed for the purposes of examining the circulatory and respiratory systems (heart and breath sounds), as well as the gastrointestinal system (bowel sounds).Pars interarticularisChronic lung diseaseBlunt splenic trauma: Blunt splenic trauma occurs when a significant impact to the spleen from some outside source (i.e.Vinculum (ligament): In anatomy, a vinculum (pl. vincula) is a band of connective tissue, similar to a ligament, that connect a flexor tendon to a phalanx bone.Electronic apex locator: 200px|right|thumbKeyboard buffer: A keyboard buffer is a section of computer memory used to hold keystrokes before they are processed.Inkjet solar cell: Inkjet solar cells are solar cells manufactured by low-cost, low-tech methods that use an inkjet printer to lay down the semiconductor material and the electrodes onto a solar cell substrate.Asbestos-related diseases: Asbestos-related diseases are disorders of the lung and pleura caused by the inhalation of asbestos fibres. Asbestos-related diseases include non-malignant disorders such as asbestosis (pulmonary fibrosis due to asbestos), diffuse pleural thickening, pleural plaques, pleural effusion, rounded atelectasis and malignancies such as lung cancer and malignant mesothelioma.Screen buffer: In computing, a screen buffer is a part of computer memory used by a computer application for the representation of the content to be shown on the computer display.Mucocele: A mucocele is any dilatation (typically pathologic) with accumulation of mucus.
