Disease, particularly one with clear and obvious changes in structure or function; the study of same.... pathology
Indicative of, or caused by, a disease or condition.... pathological
An organism or substance which caused diseases.... pathogen
This term means disease-producing, and is a term applied, for example, to bacteria capable of causing disease.... pathogenic
A term applied to signs or symptoms which are especially characteristic of certain diseases, and on the presence or absence of which the diagnosis depends. Thus the discovery of the Mycobacterium tuberculosis in the sputum is said to be pathognomonic of pulmonary tuberculosis.... pathognomonic
A pre?x indicating relationship to a disease – for example, PATHOLOGY, a study of disease.... patho
The ways in which a disease or disorder starts and develops. The term applies in particular to the physiological and cellular activities that are involved in the mode of origin and development of the condition.... pathogenesis
A suffix that denotes a disease or disorder.... pathy
An agreed and explicit route an individual takes through health and social care services. Agreements between the various providers involved will typically cover the type of care and treatment, which professional will be involved and their level of skills, and where treatment or care will take place. See also “care plan”; “care programme”.... care pathway
A multidisciplinary set of daily prescriptions and outcome targets for managing the overall care of a specific type of patient, e.g. from pre-admission to post-discharge for patients receiving inpatient care. Clinical pathways are often intended to maintain or improve quality of care and decrease costs for patients in particular diagnosis-related groups.... clinical pathway
A treatment protocol based on a consensus of clinicians that includes only those few vital components or items proved to affect patient outcomes, either by the omission or commission of the treatment or the timing of the intervention.... critical pathway
Ability to cause disease.... pathogenicity
Micro-organisms that cause diseases, parasitising plants, animals and humans (see PARASITE). Some organisms are frequently PATHOGENIC, whereas others rarely cause disease. Opportunistic pathogens are those which rarely cause serious infection in healthy people but can do so in patients with weakened immune systems (immunocompromised – see IMMUNITY). Pathogens include BACTERIA, viruses (see VIRUS), prions (see PRION), fungi (see FUNGUS), PROTOZOA and metazoa (multicellular microorganisms called HELMINTHS or worms). The pathogenicity of an organism is called its virulence, which is measured by the number of organisms required to cause disease. The 50 per cent of lethal dose (LD50) is the quantity of a particular pathogen needed to cause infection in half of the hosts invaded.... pathogens
A doctor that specialises in the interpretation of changes in tissues.... pathologist
The atypical mycobacteria. The commonest PPEM to cause human disease is the Mycobacterium avium-intracellulare complex. PPEM differ from M. tuberculosis in their source (environmental or zoonotic), rate of growth, temperature of growth and ability to produce pigment on culture. Mostly infect immunologically compromised humans and the disease caused by some species may be clinicallyindistinguishable from true human tuberculosis.... potentially pathogenic environmental mycobacteria (ppem)
Chronic inability to resist impulses to gamble, resulting in personal or social problems.... gambling, pathological
Also called cytopathology, the branch of cytology concerned with the effects of disease on cells.... pathology, cellular
Another name for clinical biochemistry, the study of abnormalities in the chemistry of body tissues in disease.... pathology, chemical
The study of the effects of disease on body functions.... pathophysiology
an extra electrical conduction pathway between the atria and ventricles, anatomically separate from the *atrioventricular node, that predisposes to *re-entry tachycardia. The pathway conducts faster than the atrioventricular node, giving rise to pre-excitation recognized by a characteristic delta wave at the beginning of the QRS complex on the electrocardiogram in normal rhythm. The presence of this pathway, with the occurrence of intermittent tachycardias, is known as the *Wolff-Parkinson-White syndrome.... accessory pathway
the route that a patient takes through the health-care system, from first admission to a hospital or treatment centre to final discharge. This may consist of one or more *spells in particular hospitals and one or more *finished consultant episodes. For example, a patient admitted to a district general hospital, transferred to a tertiary hospital for a specialist procedure, and then transferred back to the district general hospital for recovery would experience one continuous patient pathway but three spells.... continuous patient pathway
a multidisciplinary plan for delivering health and social care to patients with a specific condition or set of symptoms. Such plans are often used for the management of common conditions and are intended to improve patient care by reducing unnecessary deviation from best practice. See clinical governance.... integrated care pathway
a fracture through diseased or abnormal bone, usually resulting from a force insufficient to fracture a normal bone. Tumour, infection, congenital bone defects, and osteoporosis are among the causes.... pathological fracture
see optic nerve.... visual pathway
