Adolph Kussmaul
Adolph Kußmaul (german: Carl Philipp Adolf Konrad Kußmaul; 22 February 1822 – 28 May 1902) was a German physician and a leading clinician of his time. He was born as the son and grandson of physicians at Graben near Karlsruhe and studied at Heidelberg. He entered the army after graduation and spent two years as an army surgeon. This was followed by a period as a general practitioner before he went to Würzburg to study for his doctorate under Virchow. He was subsequently Professor of Medicine at Heidelberg (1857), Erlangen (1859), Freiburg (1859) and Straßburg (1876). Beyond his medical skills he was also active in literature. He is regarded as one of the creators of the term Biedermeier. He died in Heidelberg. Eponymous terms His name continues to be used in eponyms. He described two medical signs and one disease which have eponymous names that remain in use: * Kussmaul breathing - Very deep and labored breathing with normal, rapid or reduced frequency seen in severe Dia ...

Jugular Venous Pressure
The jugular venous pressure (JVP, sometimes referred to as ''jugular venous pulse'') is the indirectly observed pressure over the venous system via visualization of the internal jugular vein. It can be useful in the differentiation of different forms of heart and lung disease. Classically three upward deflections and two downward deflections have been described. * The upward deflections are the "a" (atrial contraction), "c" (ventricular contraction and resulting bulging of tricuspid into the right atrium during isovolumetric systole) and "v" (venous filling). * The downward deflections of the wave are the "x" descent (the atrium relaxes and the tricuspid valve moves downward) and the "y" descent (filling of ventricle after tricuspid opening). Method Visualization The patient is positioned at a 45° incline, and the filling level of the external jugular vein determined. The internal jugular vein is visualised when looking for the pulsation. In healthy people, the filling level of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleural Tap
Thoracentesis , also known as thoracocentesis (from Greek ''thōrax'' 'chest, thorax'—GEN ''thōrakos''—and ''kentēsis'' 'pricking, puncture'), pleural tap, needle thoracostomy, or needle decompression (often used term), is an invasive medical procedure to remove fluid or air from the pleural space for diagnostic or therapeutic purposes. A cannula, or hollow needle, is carefully introduced into the thorax, generally after administration of local anesthesia. The procedure was first performed by Morrill Wyman in 1850 and then described by Henry Ingersoll Bowditch in 1852. The recommended location varies depending upon the source. Some sources recommend the midaxillary line, in the eighth, ninth, or tenth intercostal space. Whenever possible, the procedure should be performed under ultrasound guidance, which has shown to reduce complications. Tension pneumothorax is a medical emergency that requires emergent needle decompression before a chest tube is placed. Indications 48 ...

Mesenteric Embolism
The mesentery is an organ that attaches the intestines to the posterior abdominal wall in humans and is formed by the double fold of peritoneum. It helps in storing fat and allowing blood vessels, lymphatics, and nerves to supply the intestines, among other functions. The mesocolon was thought to be a fragmented structure, with all named parts—the ascending, transverse, descending, and sigmoid mesocolons, the mesoappendix, and the mesorectum—separately terminating their insertion into the posterior abdominal wall. However, in 2012, new microscopic and electron microscopic examinations showed the mesocolon to be a single structure derived from the duodenojejunal flexure and extending to the distal mesorectal layer. Thus, the mesentery is an internal organ. Structure The mesentery of the small intestine arises from the root of the mesentery (or mesenteric root) and is the part connected with the structures in front of the vertebral column. The root is narrow, about 15 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Progressive Bulbar Paralysis
Progressive bulbar palsy (PBP) is a medical condition. It belongs to a group of disorders known as motor neuron diseases. Lapiedra 2002 PBP is a disease that attacks the nerves supplying the bulbar muscles. These disorders are characterized by the degeneration of motor neurons in the cerebral cortex, spinal cord, brain stem, and pyramidal tracts. This specifically involves the glossopharyngeal nerve (IX), vagus nerve (X), and hypoglossal nerve (XII). Hughes 1998 This disorder should not be confused with pseudobulbar palsy or progressive spinal muscular atrophy. The term infantile progressive bulbar palsy is used to describe progressive bulbar palsy in children. The ICD-11 lists progressive bulbar palsy as a variant of amyotrophic lateral sclerosis (ALS). Signs and symptoms Prognosis for PBP patients is poor. Progressive bulbar palsy symptoms can include progressive difficulty with talking and swallowing. Merck 2005 Patients can also exhibit reduced gag reflexes, weak palatal m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyarteritis Nodosa
Polyarteritis nodosa (PAN) is a systemic necrotizing inflammation of blood vessels (vasculitis) affecting medium-sized muscular arteries, typically involving the arteries of the kidneys and other internal organs but generally sparing the lungs' circulation. Small aneurysms are strung like the beads of a rosary, therefore making this "rosary sign" an important diagnostic feature of the vasculitis. PAN is sometimes associated with infection by the hepatitis B or hepatitis C virus. The condition may be present in infants. PAN is a rare disease. With treatment, five-year survival is 80%; without treatment, five-year survival is 13%. Death is often a consequence of kidney failure, myocardial infarction, or stroke. Signs and symptoms PAN may affect nearly every organ system and thus can present with a broad array of signs and symptoms. These manifestations result from ischemic damage to affected organs, often the skin, heart, kidneys, and nervous system. Constitutional symptoms are see ...

Dyslexia
Dyslexia, also known until the 1960s as word blindness, is a disorder characterized by reading below the expected level for one's age. Different people are affected to different degrees. Problems may include difficulties in spelling words, reading quickly, writing words, "sounding out" words in the head, pronouncing words when reading aloud and understanding what one reads. Often these difficulties are first noticed at school. The difficulties are involuntary, and people with this disorder have a normal desire to learn. People with dyslexia have higher rates of attention deficit hyperactivity disorder (ADHD), developmental language disorders, and difficulties with numbers. Dyslexia is believed to be caused by the interaction of genetic and environmental factors. Some cases run in families. Dyslexia that develops due to a traumatic brain injury, stroke, or dementia is sometimes called "acquired dyslexia" or alexia. The underlying mechanisms of dyslexia result from differ ...

Selective Mutism
Selective mutism (SM) is an anxiety disorder in which a person who is otherwise capable of speech becomes unable to speak when exposed to specific situations, specific places, or to specific people, one or multiple of which serving as triggers. This is caused by the freeze response. Selective mutism usually co-exists with social anxiety disorder. People with selective mutism stay silent even when the consequences of their silence include shame, social ostracism, or punishment. Signs and symptoms Children and adults with selective mutism are fully capable of speech and understanding language but are completely unable to speak in certain situations, though speech is expected of them. The behaviour may be perceived as shyness or rudeness by others. A child with selective mutism may be completely silent at school for years but speak quite freely or even excessively at home. There is a hierarchical variation among people with this disorder: some people participate fully in activiti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diabetic Coma
Diabetic coma is a life-threatening but reversible form of coma found in people with diabetes mellitus. Three different types of diabetic coma are identified: #Severe low blood sugar in a diabetic person #Diabetic ketoacidosis (usually type 1) advanced enough to result in unconsciousness from a combination of a severely increased blood sugar level, dehydration and shock, and exhaustion # Hyperosmolar nonketotic coma (usually type 2) in which an extremely high blood sugar level and dehydration alone are sufficient to cause unconsciousness. In most medical contexts, the term diabetic coma refers to the diagnostical dilemma posed when a physician is confronted with an unconscious patient about whom nothing is known except that they have diabetes. An example might be a physician working in an emergency department who receives an unconscious patient wearing a medical identification tag saying DIABETIC. Paramedics may be called to rescue an unconscious person by friends who identify ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rudolf Robert Maier
Rudolf Robert Maier (9 April 1824 – 7 November 1888) was a German pathologist who was a native of Freiburg im Breisgau. He studied medicine at the University of Freiburg, where one of his instructors was orthopedist Louis Stromeyer (1804–1876). He furthered his medical training in Vienna with Carl Freiherr von Rokitansky, Carl Rokitansky (1804–1878), Joseph Hyrtl (1810–1894) and Josef Skoda (1805–1881), and in Würzburg under Rudolf Virchow (1821–1902). Afterwards, he returned to Freiburg, where in 1859 he became an associate professor. He later attained a full professorship, and in 1864 founded the first institute of pathological anatomy at Freiburg. With Adolf Kussmaul (1822–1902), Maier provided the first comprehensive description of periarteritis nodosa, a condition sometimes referred to as "Kussmaul-Maier disease". The two doctors described their findings in the inaugural edition of the journal ''Deutsches Archiv für klinische Medicin'', a publication co-founded ...
