Label	Id	Description
Arthritis, Juvenile	D001171	[Arthritis in children, with onset before 16 years of age. The terms juvenile rheumatoid arthritis (JRA) and juvenile idiopathic arthritis (JIA) refer to classification systems for chronic arthritis in children. Only one subtype of juvenile arthritis (polyarticular-onset, rheumatoid factor-positive) clinically resembles adult rheumatoid arthritis and is considered its childhood equivalent.]
Arthritis, Psoriatic	D015535	[A type of inflammatory arthritis associated with PSORIASIS, often involving the axial joints and the peripheral terminal interphalangeal joints. It is characterized by the presence of HLA-B27-associated SPONDYLARTHROPATHY, and the absence of rheumatoid factor.]
Arthritis, Reactive	D016918	[Historically characterized by a triad of inflammation involving the eye (CONJUNCTIVITIS), the bone (POST-INFECTIOUS ARTHRITIS), and the urethra (URETHRITIS), it is now thought to be nearly synonymous with reactive arthritis., An aseptic, inflammatory arthritis developing secondary to a primary extra-articular infection, most typically of the GASTROINTESTINAL TRACT or UROGENITAL SYSTEM. The initiating trigger pathogens are usually SHIGELLA; SALMONELLA; YERSINIA; CAMPYLOBACTER; or CHLAMYDIA TRACHOMATIS. Reactive arthritis is strongly associated with HLA-B27 ANTIGEN.]
Arthritis, Rheumatoid	D001172	[A chronic systemic disease, primarily of the joints, marked by inflammatory changes in the synovial membranes and articular structures, widespread fibrinoid degeneration of the collagen fibers in mesenchymal tissues, and by atrophy and rarefaction of bony structures. Etiology is unknown, but autoimmune mechanisms have been implicated.]
Arthrogryposis	D001176	[Persistent flexure or contracture of a joint.]
Arthropathy, Neurogenic	D001177	[Chronic progressive degeneration of the stress-bearing portion of a joint, with bizarre hypertrophic changes at the periphery. It is probably a complication of a variety of neurologic disorders, particularly TABES DORSALIS, involving loss of sensation, which leads to relaxation of supporting structures and chronic instability of the joint. (Dorland, 27th ed)]
Arthus Reaction	D001183	[A dermal inflammatory reaction produced under conditions of antibody excess, when a second injection of antigen produces intravascular antigen-antibody complexes which bind complement, causing cell clumping, endothelial damage, and vascular necrosis.]
Articulation Disorders	D001184	[Disorders of the quality of speech characterized by the substitution, omission, distortion, and addition of phonemes.]
Artificial Lens Implant Migration	D060437	[The shifting and or tilting of implanted artificial lens resulting in impaired vision.]
Asbestosis	D001195	[A form of pneumoconiosis caused by inhalation of asbestos fibers which elicit potent inflammatory responses in the parenchyma of the lung. The disease is characterized by interstitial fibrosis of the lung, varying from scattered sites to extensive scarring of the alveolar interstitium.]
Ascariasis	D001196	[Infection by nematodes of the genus ASCARIS. Ingestion of infective eggs causes diarrhea and pneumonitis. Its distribution is more prevalent in areas of poor sanitation and where human feces are used for fertilizer.]
Ascaridiasis	D001198	[Infection with nematodes of the genus ASCARIDIA. This condition usually occurs in fowl, often manifesting diarrhea.]
Ascaridida Infections	D017191	[Infections with nematodes of the order ASCARIDIDA.]
Ascites	D001201	[Accumulation or retention of free fluid within the peritoneal cavity.]
Ascorbic Acid Deficiency	D001206	[A condition due to a dietary deficiency of ascorbic acid (vitamin C), characterized by malaise, lethargy, and weakness. As the disease progresses, joints, muscles, and subcutaneous tissues may become the sites of hemorrhage. Ascorbic acid deficiency frequently develops into SCURVY in young children fed unsupplemented cow's milk exclusively during their first year. It develops also commonly in chronic alcoholism. (Cecil Textbook of Medicine, 19th ed, p1177)]
Aspartylglucosaminuria	D054880	[A recessively inherited, progressive lysosomal storage disease caused by a deficiency of GLYCOSYLASPARAGINASE activity. The lack of this enzyme activity results in the accumulation of N-acetylglucosaminylasparagine (the linkage unit of asparagine-linked glycoproteins) in LYSOSOMES.]
Aspergillosis	D001228	[Infections with fungi of the genus ASPERGILLUS.]
Aspergillosis, Allergic Bronchopulmonary	D001229	[Hypersensitivity reaction (ALLERGIC REACTION) to fungus ASPERGILLUS in an individual with long-standing BRONCHIAL ASTHMA. It is characterized by pulmonary infiltrates, EOSINOPHILIA, elevated serum IMMUNOGLOBULIN E, and skin reactivity to Aspergillus antigen.]
Aspermia	D053714	[A condition characterized by the complete absence of SEMEN. This disorder should be differentiated from AZOOSPERMIA, absence of sperm in the semen.]
Asphyxia	D001237	[A pathological condition caused by lack of oxygen, manifested in impending or actual cessation of life.]
