Valentino's Syndrome
Valentino's syndrome is pain presenting in the right lower quadrant of the abdomen caused by a duodenal ulcer with perforation through the retroperitoneum. It is named after Rudolph Valentino, an Italian actor, who presented with right lower quadrant pain in New York, which turned out to be a perforated peptic ulcer. He subsequently died from an infection and organ dysfunction in spite of surgery to repair the perforation. Due to his popularity, his case received much attention at the time and is still considered a rare medical condition. However, the degree of peritoneal findings is strongly influenced by a number of factors, including the size of perforation, amount of bacterial and gastric contents contaminating the abdominal cavity, time between perforation and presentation, and spontaneous sealing of perforation. Signs and symptoms Patients with perforated Valentino's syndrome usually present with a sudden onset of severe, sharp abdominal pain in the right lower quadrant (RL ...

Right Lower Quadrant
The human abdomen is divided into quadrants and regions by anatomists and physicians for the purposes of study, diagnosis, and treatment. The division into four quadrants allows the localisation of pain and tenderness, scars, lumps, and other items of interest, narrowing in on which organs and tissues may be involved. The quadrants are referred to as the left lower quadrant, left upper quadrant, right upper quadrant and right lower quadrant. These terms are not used in comparative anatomy, since most other animals do not stand erect. The left lower quadrant includes the left iliac fossa and half of the flank. The equivalent in other animals is ''left posterior quadrant''. The left upper quadrant extends from the umbilical plane to the left ribcage. This is the ''left anterior quadrant'' in other animals. The right upper quadrant extends from umbilical plane to the right ribcage. The equivalent in other animals is ''right anterior quadrant''. The right lower quadrant extends ...

Nausea
Nausea is a diffuse sensation of unease and discomfort, sometimes perceived as an urge to vomit. While not painful, it can be a debilitating symptom if prolonged and has been described as placing discomfort on the chest, abdomen, or back of the throat. Over 30 definitions of nausea were proposed in a 2011 book on the topic. Nausea is a non-specific symptom, which means that it has many possible causes. Some common causes of nausea are gastroenteritis and other gastrointestinal disorders, food poisoning, motion sickness, dizziness, migraine, fainting, low blood sugar, anxiety, and lack of sleep. Nausea is a side effect of many medications including chemotherapy, or morning sickness in early pregnancy. Nausea may also be caused by disgust and depression. Medications taken to prevent and treat nausea and vomiting are called antiemetics. The most commonly prescribed antiemetics in the US are promethazine, metoclopramide, and the newer ondansetron. The word nausea is from Lat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rovsing's Sign
Rovsing's sign, named after the Danish surgeon Niels Thorkild Rovsing (1862–1927), is a sign of appendicitis. If palpation of the left lower quadrant of a person's abdomen increases the pain felt in the right lower quadrant, the patient is said to have a positive Rovsing's sign and may have appendicitis. The phenomenon was first described by Swedish surgeon Emil Samuel Perman (1856-1945) writing in the journal ''Hygiea'' in 1904. In acute appendicitis, palpation in the left iliac fossa may produce pain in the right iliac fossa. Referral of pain This anomaly occurs because the pain nerves deep in the intestines do not localize well to an exact spot on the abdominal wall, unlike pain nerves in muscles. Pain from a stomach ulcer or gallstone can be interpreted by the brain as pain from the stomach, liver, gall bladder, duodenum, or first part of the small intestine. It will "refer" pain often to the mid upper abdomen, the epigastrum. Because the appendix is a piece of inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blumberg's Sign
Blumberg's sign (also referred to as rebound tenderness or Shchetkin–Blumberg's sign) is a clinical sign in which there is pain upon removal of pressure rather than application of pressure to the abdomen. (The latter is referred to simply as ''abdominal tenderness''.) It is indicative of peritonitis. It was named after German surgeon Jacob Moritz Blumberg. Procedure The abdominal wall is compressed slowly and then rapidly released. A positive sign is indicated by presence of pain upon removal of pressure on the abdominal wall. Clinical significance The sign indicates aggravation of the parietal peritoneum by stretching or moving. Positive Blumberg's sign is indicative of peritonitis, which can occur in diseases like appendicitis, and may occur in ulcerative colitis with rebound tenderness in the right lower quadrant. However, in recent years the value of rebound tenderness has been questioned, since it may not add any diagnostic value beyond the observation that the patient ha ...

McBurney's Point
McBurney's point is the name given to the point over the right side of the abdomen that is one-third of the distance from the anterior superior iliac spine to the umbilicus (navel). This is near the most common location of the appendix. Location McBurney's point is located one third of the distance from the right anterior superior iliac spine to the umbilicus (navel). This point roughly corresponds to the most common location of the base of the appendix, where it is attached to the cecum. Clinical significance Appendicitis Deep tenderness at McBurney's point, known as McBurney's sign, is a sign of acute appendicitis. The clinical sign of referred pain in the epigastrium when pressure is applied is also known as Aaron's sign. Specific localization of tenderness to McBurney's point indicates that inflammation is no longer limited to the lumen of the bowel (which localizes pain poorly), and is irritating the lining of the peritoneum at the place where the peritoneum comes ...

Abdominal Guarding
Abdominal guarding is the tensing of the abdominal muscles, abdominal wall muscles to guard inflamed organs within the abdomen from the pain of pressure upon them. The tensing is detected when the abdominal wall is pressed. Abdominal guarding is also known as défense musculaire. Guarding is a characteristic finding in the physical examination for an abruptly painful abdomen (an acute abdomen) with inflammation of the inner abdominal (peritoneal) surface due, for example, to appendicitis or diverticulitis. The tensed muscles of the abdominal wall automatically go into spasm to keep the tender underlying tissues from being disturbed. Diagnosis D ...

Tenderness (medicine)
In medicine, tenderness is pain or discomfort when an affected area is touched. It should not be confused with the pain that a patient perceives without touching. Pain is patient's perception, while tenderness is a sign that a clinician elicits.

Leukocytosis
Leukocytosis is a condition in which the white cell (leukocyte count) is above the normal range in the blood. It is frequently a sign of an inflammatory response, most commonly the result of infection, but may also occur following certain parasitic infections or bone tumors as well as leukemia. It may also occur after strenuous exercise, convulsions such as epilepsy, emotional stress, pregnancy and labor, anesthesia, as a side effect of medication (e.g., lithium), and epinephrine administration. There are five principal types of leukocytosis: # Neutrophilia (the most common form) # Lymphocytosis # Monocytosis # Eosinophilia # Basophilia This increase in leukocyte (primarily neutrophils) is usually accompanied by a "left upper shift" in the ratio of immature to mature neutrophils and macrophages. The proportion of immature leukocytes increases due to proliferation and inhibition of granulocyte and monocyte precursors in the bone marrow which is stimulated by several products of infl ...

Bleeding
Bleeding, hemorrhage, haemorrhage or blood loss, is blood escaping from the circulatory system from damaged blood vessels. Bleeding can occur internally, or externally either through a natural opening such as the mouth, nose, ear, urethra, vagina or anus, or through a puncture in the skin. Hypovolemia is a massive decrease in blood volume, and death by excessive loss of blood is referred to as exsanguination. Typically, a healthy person can endure a loss of 10–15% of the total blood volume without serious medical difficulties (by comparison, blood donation typically takes 8–10% of the donor's blood volume). The stopping or controlling of bleeding is called hemostasis and is an important part of both first aid and surgery. Types * Upper head ** Intracranial hemorrhage – bleeding in the skull. ** Cerebral hemorrhage – a type of intracranial hemorrhage, bleeding within the brain tissue itself. ** Intracerebral hemorrhage – bleeding in the brain caused by the ruptur ...

Peritoneum
The peritoneum is the serous membrane forming the lining of the abdominal cavity or coelom in amniotes and some invertebrates, such as annelids. It covers most of the intra-abdominal (or coelomic) organs, and is composed of a layer of mesothelium supported by a thin layer of connective tissue. This peritoneal lining of the cavity supports many of the abdominal organs and serves as a conduit for their blood vessels, lymphatic vessels, and nerves. The abdominal cavity (the space bounded by the vertebrae, abdominal muscles, diaphragm, and pelvic floor) is different from the intraperitoneal space (located within the abdominal cavity but wrapped in peritoneum). The structures within the intraperitoneal space are called "intraperitoneal" (e.g., the stomach and intestines), the structures in the abdominal cavity that are located behind the intraperitoneal space are called "retroperitoneal" (e.g., the kidneys), and those structures below the intraperitoneal space are called "subp ...
