Ten Horn's Sign
Ten Horn's sign is a clinical sign used for diagnosing appendicitis, particularly in older adults. Method The patient lies on a couch. The examiner gently stretches the right spermatic cord using the thumb and index finger right about the testis in the right scrotum. For a patient with appendicitis, this causes pain in the right iliac fossa The iliac fossa is a large, smooth, concave surface on the internal surface of the Ilium (bone), ilium (part of the three fused bones making the hip bone). Structure The iliac fossa is bounded above by the iliac crest, and below by the Arcuate l .... The traction of spermatic cord is thought to cause right iliac fossa pain due to the apposition of the gonadal vessels against an inflamed appendix. The sensitivity and specificity of the Ten Horn's sign is unknown. History This sign was proposed by Carel Hendrik Leo Herman ten Horn (1884–1964).

Clinical Sign
Signs and symptoms are the observed or detectable signs, and experienced symptoms of an illness, injury, or condition. A sign for example may be a higher or lower temperature than normal, raised or lowered blood pressure or an abnormality showing on a medical scan. A symptom is something out of the ordinary that is experienced by an individual such as feeling feverish, a headache or other pain or pains in the body. Signs and symptoms Signs A medical sign is an objective observable indication of a disease, injury, or abnormal physiological state that may be detected during a physical examination, examining the patient history, or diagnostic procedure. These signs are visible or otherwise detectable such as a rash or bruise. Medical signs, along with symptoms, assist in formulating diagnostic hypothesis. Examples of signs include elevated blood pressure, nail clubbing of the fingernails or toenails, staggering gait, and arcus senilis and arcus juvenilis of the eyes. Indication ...

Appendicitis
Appendicitis is inflammation of the appendix. Symptoms commonly include right lower abdominal pain, nausea, vomiting, and decreased appetite. However, approximately 40% of people do not have these typical symptoms. Severe complications of a ruptured appendix include widespread, painful inflammation of the inner lining of the abdominal wall and sepsis. Appendicitis is caused by a blockage of the hollow portion of the appendix. This is most commonly due to a calcified "stone" made of feces. Inflamed lymphoid tissue from a viral infection, parasites, gallstone, or tumors may also cause the blockage. This blockage leads to increased pressures in the appendix, decreased blood flow to the tissues of the appendix, and bacterial growth inside the appendix causing inflammation. The combination of inflammation, reduced blood flow to the appendix and distention of the appendix causes tissue injury and tissue death. If this process is left untreated, the appendix may burst, releasing ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spermatic Cord
The spermatic cord is the cord-like structure in males formed by the vas deferens (''ductus deferens'') and surrounding tissue that runs from the deep inguinal ring down to each testicle. Its serosal covering, the tunica vaginalis, is an extension of the peritoneum that passes through the transversalis fascia. Each testicle develops in the lower thoracic and upper lumbar region and migrates into the scrotum. During its descent it carries along with it the vas deferens, its vessels, nerves etc. There is one on each side. Structure The spermatic cord is ensheathed in three layers of tissue: * ''external spermatic fascia'', an extension of the innominate fascia that overlies the aponeurosis of the external oblique muscle. * ''cremasteric muscle and fascia'', formed from a continuation of the internal oblique muscle and its fascia. * ''internal spermatic fascia'', continuous with the transversalis fascia. The normal diameter of the spermatic cord is about 16 mm (range 11 to 22 mm). It ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iliac Fossa
The iliac fossa is a large, smooth, concave surface on the internal surface of the Ilium (bone), ilium (part of the three fused bones making the hip bone). Structure The iliac fossa is bounded above by the iliac crest, and below by the Arcuate line (ilium), arcuate line. It is bordered in front and behind by the anterior and posterior borders of the Ilium (bone), ilium. The iliac fossa gives origin to the iliacus muscle. The obturator nerve passes around the iliac fossa. It is perforated at its inner part by a nutrient canal. Below it there is a smooth, rounded border, the arcuate line (ilium), arcuate line, which runs anterior, inferior, and medial. When the "left" or "right" adjective is used (e.g "right iliac fossa"), the iliac fossa usually means one of the groin, inguinal regions of the Quadrants and regions of abdomen, nine regions of the abdomen.

Sensitivity And Specificity
''Sensitivity'' and ''specificity'' mathematically describe the accuracy of a test which reports the presence or absence of a condition. Individuals for which the condition is satisfied are considered "positive" and those for which it is not are considered "negative". *Sensitivity (true positive rate) refers to the probability of a positive test, conditioned on truly being positive. *Specificity (true negative rate) refers to the probability of a negative test, conditioned on truly being negative. If the true condition can not be known, a " gold standard test" is assumed to be correct. In a diagnostic test, sensitivity is a measure of how well a test can identify true positives and specificity is a measure of how well a test can identify true negatives. For all testing, both diagnostic and screening, there is usually a trade-off between sensitivity and specificity, such that higher sensitivities will mean lower specificities and vice versa. If the goal is to return the ratio at w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medical Diagnosis
Medical diagnosis (abbreviated Dx, Dx, or Ds) is the process of determining which disease or condition explains a person's symptoms and signs. It is most often referred to as diagnosis with the medical context being implicit. The information required for diagnosis is typically collected from a history and physical examination of the person seeking medical care. Often, one or more diagnostic procedures, such as medical tests, are also done during the process. Sometimes posthumous diagnosis is considered a kind of medical diagnosis. Diagnosis is often challenging because many signs and symptoms are nonspecific. For example, redness of the skin (erythema), by itself, is a sign of many disorders and thus does not tell the healthcare professional what is wrong. Thus differential diagnosis, in which several possible explanations are compared and contrasted, must be performed. This involves the correlation of various pieces of information followed by the recognition and differentiat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
