Label	Id	Description
Atrial Premature Complexes	D018880	[A type of cardiac arrhythmia with premature atrial contractions or beats caused by signals originating from ectopic atrial sites. The ectopic signals may or may not conduct to the HEART VENTRICLES. Atrial premature complexes are characterized by premature P waves on ECG which are different in configuration from the P waves generated by the normal pacemaker complex in the SINOATRIAL NODE.]
Atrial Remodeling	D064752	[Long-term changes in the electrophysiological parameters and/or anatomical structures of the HEART ATRIA that result from prolonged changes in atrial rate, often associated with ATRIAL FIBRILLATION or long periods of intense EXERCISE.]
Atrioventricular Block	D054537	[Impaired impulse conduction from HEART ATRIA to HEART VENTRICLES. AV block can mean delayed or completely blocked impulse conduction.]
Atrophic Vaginitis	D059268	[Inflammation of the vagina due to thinning of the vaginal wall and decreased lubrication associated with reduced estrogen levels at MENOPAUSE.]
Atrophy	D001284	[Decrease in the size of a cell, tissue, organ, or multiple organs, associated with a variety of pathological conditions such as abnormal cellular changes, ischemia, malnutrition, or hormonal changes.]
Atypical Hemolytic Uremic Syndrome	D065766	[An hereditary hemolytic uremic syndrome associated with variations in the gene that encodes COMPLEMENT FACTOR H, or the related proteins CFHR1 and CFHR3. Disease often progresses to CHRONIC KIDNEY FAILURE without the prodromal symptoms of ENTEROCOLITIS and DIARRHEA that characterize typical hemolytic uremic syndrome.]
Atypical Squamous Cells of the Cervix	D065309	[Morphological abnormalities of the cervical EPITHELIUM, usually revealed in PAP SMEAR, which do not meet the criteria for squamous CERVICAL INTRAEPITHELIAL NEOPLASIA or SQUAMOUS CELL CARCINOMAS of the CERVIX . It may be a sign of infection with certain types of human papillomavirus (HPV).or sign of a benign (not cancer) growth, such as a cyst or polyp or, in menopausal women, of low hormone levels. More testing, such as HPV test, may be needed.]
Auditory Diseases, Central	D001304	[Disorders of hearing or auditory perception due to pathological processes of the AUDITORY PATHWAYS in the CENTRAL NERVOUS SYSTEM. These include CENTRAL HEARING LOSS and AUDITORY PERCEPTUAL DISORDERS.]
Auditory Perceptual Disorders	D001308	[Acquired or developmental cognitive disorders of AUDITORY PERCEPTION characterized by a reduced ability to perceive information contained in auditory stimuli despite intact auditory pathways. Affected individuals have difficulty with speech perception, sound localization, and comprehending the meaning of inflections of speech.]
Autoimmune Diseases	D001327	[Disorders that are characterized by the production of antibodies that react with host tissues or immune effector cells that are autoreactive to endogenous peptides.]
Autoimmune Diseases of the Nervous System	D020274	[Disorders caused by cellular or humoral immune responses primarily directed towards nervous system autoantigens. The immune response may be directed towards specific tissue components (e.g., myelin) and may be limited to the central nervous system (e.g., MULTIPLE SCLEROSIS) or the peripheral nervous system (e.g., GUILLAIN-BARRE SYNDROME).]
Autoimmune Hypophysitis	D000069281	[Immune-mediated inflammation of the PITUITARY GLAND often associated with other autoimmune diseases (e.g., HASHIMOTO DISEASE; GRAVES DISEASE; and ADDISON DISEASE).]
Autoimmune Lymphoproliferative Syndrome	D056735	[Rare congenital lymphoid disorder due to mutations in certain Fas-Fas ligand pathway genes. Known causes include mutations in FAS, TNFSF6, NRAS, CASP8, and CASP10 proteins. Clinical features include LYMPHADENOPATHY; SPLENOMEGALY; and AUTOIMMUNITY., Autoimmune lymphoproliferative syndrome due to mutations in CASPASE 8 gene.]
Autolysis	D001329	[The spontaneous disintegration of tissues or cells by the action of their own autogenous enzymes.]
Autonomic Dysreflexia	D020211	[A syndrome associated with damage to the spinal cord above the mid thoracic level (see SPINAL CORD INJURIES) characterized by a marked increase in the sympathetic response to minor stimuli such as bladder or rectal distention. Manifestations include HYPERTENSION; TACHYCARDIA (or reflex bradycardia); FEVER; FLUSHING; and HYPERHIDROSIS. Extreme hypertension may be associated with a STROKE. (From Adams et al., Principles of Neurology, 6th ed, pp538 and 1232; J Spinal Cord Med 1997;20(3):355-60)]
Autonomic Nervous System Diseases	D001342	[Diseases of the parasympathetic or sympathetic divisions of the AUTONOMIC NERVOUS SYSTEM; which has components located in the CENTRAL NERVOUS SYSTEM and PERIPHERAL NERVOUS SYSTEM. Autonomic dysfunction may be associated with HYPOTHALAMIC DISEASES; BRAIN STEM disorders; SPINAL CORD DISEASES; and PERIPHERAL NERVOUS SYSTEM DISEASES. Manifestations include impairments of vegetative functions including the maintenance of BLOOD PRESSURE; HEART RATE; pupil function; SWEATING; REPRODUCTIVE AND URINARY PHYSIOLOGY; and DIGESTION.]
Avian Leukosis	D001353	[A group of transmissible viral diseases of chickens and turkeys. Liver tumors are found in most forms, but tumors can be found elsewhere.]
Avitaminosis	D001361	[A condition due to a deficiency of one or more essential vitamins. (Dorland, 27th ed)]
Avulavirus Infections	D045463	[Infections with viruses of the genus AVULAVIRUS, family PARAMYXOVIRIDAE. This includes NEWCASTLE DISEASE and other infections of domestic fowl.]
Azoospermia	D053713	[A condition of having no sperm present in the ejaculate (SEMEN).]
