Diagnostic Method
MEDICAL DIAGNOSIS (abbreviated 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 diagnostic tests , are also done during the process. Sometimes Posthumous diagnosis is considered a kind of medical diagnosis. 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 doesn't tell the healthcare professional what is wrong. Thus differential diagnosis , in which several possible explanations are compared and contrasted, must be performed

Radiography
RADIOGRAPHY is an imaging technique using X-rays
X-rays
to view the internal structure of an object. To create the image, a beam of X-rays, a form of electromagnetic radiation , is produced by an X-ray
X-ray
generator and is projected toward the object. A certain amount of X-ray
X-ray
is absorbed by the object, dependent its density and composition. The X-rays
X-rays
that pass through the object are captured behind the object by a detector (either photographic film or a digital detector). The generation of flat two dimensional images by this technique is called projectional radiography . Computed tomography
Computed tomography
(CT scanning) is where multiple 2D images from different angles undergo computer processing to generate 3D representations. Applications of radiography include medical (or "diagnostic") radiography and industrial radiography

Disease
A DISEASE is a particular abnormal condition that affects part or all of an organism and that consists of a disorder of a structure or function. The study of disease is called pathology , which includes the study of cause. Disease
Disease
is often construed as a MEDICAL CONDITION associated with specific symptoms and signs . It may be caused by external factors such as pathogens or by internal dysfunctions, particularly of the immune system , such as an immunodeficiency , or by a hypersensitivity , including allergies and autoimmunity . When caused by pathogens (e.g. malaria by _Plasmodium_ ssp.), the term _disease_ is often misleadingly used even in the scientific literature in place of its causal agent, the pathogen. This language habit can cause confusion in the communication of the cause-effect principle in epidemiology, and as such it should be strongly discouraged

Symptom
A SYMPTOM (from Greek σύμπτωμα, "accident, misfortune, that which befalls", from συμπίπτω, "I befall", from συν- "together, with" and πίπτω, "I fall") is a departure from normal function or feeling which is noticed by a patient , reflecting the presence of an unusual state, or of a disease . A symptom is subjective, observed by the patient, and cannot be measured directly, whereas a sign is objectively observable by others. For example, paresthesia is a symptom (only the person experiencing it can directly observe their own tingling feeling), whereas erythema is a sign (anyone can confirm that the skin is redder than usual). Symptoms and signs are often nonspecific , but often combinations of them are at least suggestive of certain diagnoses , helping to narrow down what may be wrong. In other cases they are specific even to the point of being pathognomonic

Medical Sign
A MEDICAL SIGN is an objective indication of some medical fact or characteristic that may be detected by a patient or anyone, especially a physician , before or during a physical examination of a patient . For example, whereas a tingling paresthesia is a symptom (only the person experiencing it can directly observe their own tingling feeling), erythema is a sign (anyone can confirm that the skin is redder than usual). Symptoms and signs are often nonspecific , but often combinations of them are at least suggestive of certain diagnoses , helping to narrow down what may be wrong. In other cases they are specific even to the point of being pathognomonic

Medical History
The MEDICAL HISTORY or (medical) CASE HISTORY (also called EPICRISIS – typically discharge summary to referring GP, or ANAMNESIS, especially historically) (often abbreviated HX or HX) of a patient is information gained by a physician by asking specific questions, either of the patient or of other people who know the person and can give suitable information (in this case, it is sometimes called HETEROANAMNESIS), with the aim of obtaining information useful in formulating a diagnosis and providing medical care to the patient . The medically relevant complaints reported by the patient or others familiar with the patient are referred to as symptoms , in contrast with clinical signs , which are ascertained by direct examination on the part of medical personnel. Most health encounters will result in some form of history being taken. Medical

Physical Examination
A PHYSICAL EXAMINATION, MEDICAL EXAMINATION, or CLINICAL EXAMINATION (more popularly known as a CHECK-UP) is the process by which a medical professional investigates the body of a patient for signs of disease . It generally follows the taking of the medical history —an account of the symptoms as experienced by the patient. Together with the medical history, the physical examination aids in determining the correct diagnosis and devising the treatment plan. This data then becomes part of the medical record . A Cochrane Collaboration meta-study found that routine annual physicals did not measurably reduce the risk of illness or death, and conversely, could lead to over-diagnosis and over-treatment. The authors concluded that routine physicals were unlikely to do more good than harm

Posthumous Diagnosis
A RETROSPECTIVE DIAGNOSIS (also RETRODIAGNOSIS or POSTHUMOUS DIAGNOSIS) is the practice of identifying an illness after the death of the patient, sometimes in a historical figure using modern knowledge, methods and disease classifications . Alternatively, it can be the more general attempt to give a modern name to an ancient and ill-defined scourge or plague. CONTENTS * 1 Historical research * 2 Postmortem diagnosis * 3 Examples * 4 See also * 5 References * 6 Further reading HISTORICAL RESEARCH Retrospective diagnosis is practised by medical historians, general historians and the media with varying degrees of scholarship. At its worst it may become "little more than a game, with ill-defined rules and little academic credibility". The process often requires "translating between linguistic and conceptual worlds separated by several centuries", and assumes our modern disease concepts and categories are privileged

Erythema
ERYTHEMA (from the Greek _erythros_, meaning red) is redness of the skin or mucous membranes, caused by hyperemia (increased blood flow) in superficial capillaries. It occurs with any skin injury, infection, or inflammation. Examples of erythema not associated with pathology include nervous blushes. CONTENTS * 1 Causes * 2 Diagnosis * 3 Types * 4 See also * 5 References * 6 External links CAUSESIt can be caused by infection , massage , electrical treatment, acne medication, allergies , exercise, solar radiation (sunburn ), cutaneous radiation syndrome , mercury toxicity, blister agents , niacin administration, or waxing and tweezing of the hairs—any of which can cause the capillaries to dilate, resulting in redness. Erythema is a common side effect of radiotherapy treatment due to patient exposure to ionizing radiation

Differential Diagnosis
In medicine , a DIFFERENTIAL DIAGNOSIS is the distinguishing of a particular disease or condition from others that present similar clinical features. Differential diagnostic procedures are used by physicians and other trained medical professionals to diagnose the specific disease in a patient , or, at least, to eliminate any imminently life-threatening conditions. Often, each individual option of a possible disease is called a differential diagnosis (for example, bronchitis could be a differential diagnosis in the evaluation of a cough that ends up with a final diagnosis of common cold ). More generally, a DIFFERENTIAL DIAGNOSTIC PROCEDURE is a systematic diagnostic method used to identify the presence of a disease entity where multiple alternatives are possible

Correlation
In statistics , DEPENDENCE or ASSOCIATION is any statistical relationship, whether causal or not, between two random variables or bivariate data . CORRELATION is any of a broad class of statistical relationships involving dependence, though in common usage it most often refers to the extent to which two variables have a linear relationship with each other. Familiar examples of dependent phenomena include the correlation between the physical statures of parents and their offspring, and the correlation between the demand for a product and its price. Correlations are useful because they can indicate a predictive relationship that can be exploited in practice. For example, an electrical utility may produce less power on a mild day based on the correlation between electricity demand and weather. In this example, there is a causal relationship , because extreme weather causes people to use more electricity for heating or cooling

Pathognomonic
PATHOGNOMONIC (often misspelled as pathognomic and sometimes as pathomnemonic) is a term, often used in medicine , that means characteristic for a particular disease . A pathognomonic sign is a particular sign whose presence means that a particular disease is present beyond any doubt. Labelling a sign or symptom "pathognomonic" represents a marked intensification of a "diagnostic" sign or symptom. The word is an adjective of Greek origin derived from πάθος pathos "disease" and γνώμων gnomon "indicator" (from γιγνώσκω gignosko "I know, I recognize"). CONTENTS * 1 Practical use * 2 Examples * 3 See also * 4 References * 5 External links PRACTICAL USEWhile some findings may be classic, typical or highly suggestive in a certain condition, they may not occur uniquely in this condition and therefore may not directly imply a specific diagnosis

Statistics
STATISTICS is a branch of mathematics dealing with the collection, analysis, interpretation, presentation, and organization of data . In applying statistics to, e.g., a scientific, industrial, or social problem, it is conventional to begin with a statistical population or a statistical model process to be studied. Populations can be diverse topics such as "all people living in a country" or "every atom composing a crystal." Statistics
Statistics
deals with all aspects of data including the planning of data collection in terms of the design of surveys and experiments . When census data cannot be collected, statisticians collect data by developing specific experiment designs and survey samples . Representative sampling assures that inferences and conclusions can reasonably extend from the sample to the population as a whol
