symptom Med any sensation or change in bodily function experienced by a patient that is associated with a particular disease Symptom an indication of a phenomenon, for example, of a disease. Many types of symptoms are distinguished in medicine. Constitutional symptoms characterize diseases of varying genesis and include weakness and increases in body temperature. Pathognomonic symptoms indicate a definite nosologic form; a stabbing pain in the epigastric region, for example, is typical of a perforating gastric ulcer. Subjective symptoms are only revealed upon questioning the individual, and objective symptoms are readily observable through examination, palpation, percussion, auscultation, and laboratory and instrumental diagnostic methods. Signal symptoms are the precursors of a disease. They include early symptoms, such as chest pains with pneumonia, and late symptoms, such as peritoneal irritation with cholecystitis. A disease is said to be atypical if its characteristic symptoms are absent from the very beginning; an example of an atypical disease is the painless form of myocardial infarction. Modern therapeutic measures and protective inoculations can substantially alter the symptoms of a disease and even cause them to disappear. Diagnosis and prognosis are based on a knowledge of all of the symptoms of a disease. symptom[′sim·təm] (medicine) A phenomenon of physical or mental disorder or disturbance which leads to complaints on the part of the patient. symptom

Those in the same direction as the incident light, which is drawn travelling from left to right, are positive. Those in the opposite direction are negative. (2) All distances are measured from the axis. Those above are positive. Those below are negative. (3) Angles are measured from the incident ray to the axis, with anticlockwise angles positive and clockwise angles negative. (4) The power of a converging lens is positive and that of a diverging lens is negative (Fig. S7). See focal length; Lagrange's law; law of refraction; Newton's formula; fundamental paraxial equation.
