Pathology is the medical discipline that describes conditions typically observed during a disease state, whereas physiology is the biological discipline that describes processes or mechanisms operating within an organism. Pathology describes the abnormal or undesired condition (symptoms of a disease), whereas pathophysiology seeks to explain ...
Examples of important subdivisions in medical imaging include radiology (which uses the imaging technologies of X-ray radiography) magnetic resonance imaging, medical ultrasonography (or ultrasound), endoscopy, elastography, tactile imaging, thermography, medical photography, nuclear medicine and functional imaging techniques such as positron ...
The pathological perspective can be directly integrated into an epidemiological approach in the interdisciplinary field of molecular pathological epidemiology. [6] Molecular pathological epidemiology can help to assess pathogenesis and causality by means of linking a potential risk factor to molecular pathologic signatures of a disease. [ 7 ]
For example, the estrogen-dependent uterine cells undergo hyperplasia and hypertrophy following pregnancy. Pathologic hyperplasia is an abnormal increase in cell division. A common pathologic hyperplasia in women occurs in the endometrium and is called endometriosis. [7]
Anatomic pathology relates to the processing, examination, and diagnosis of surgical specimens by a physician trained in pathological diagnosis. Clinical pathology involves the laboratory analysis of tissue samples and bodily fluids; procedures may include blood sample analysis, urinalysis, stool sample analysis, and analysis of spinal fluid ...
For example, hemolysis, icterus, lipemia, or heterophile antibodies may confound results obtained by traditional methods such as ion-selective electrodes, enzymatic assays or immunoassays. Alternate methods such as blood gas analysers, point-of-care testing or mass spectrometry may help resolve the clinical question.
The following is a list of genetic disorders and if known, type of mutation and for the chromosome involved. Although the parlance "disease-causing gene" is common, it is the occurrence of an abnormality in the parents that causes the impairment to develop within the child.
This condition is caused by the deceased liver's decreased ability to esterificate cholesterol. [60] Thalassemia: D56: D013789 Thalassaemia is an inherited blood disorder which is caused by genetic mutations that causes the body to make fewer healthy red blood cells and less hemoglobin due to lack of protein chains. Triosephosphate isomerase ...
