Label	Id	Description
Arm Injuries	D001134	[General or unspecified injuries involving the UPPER ARM and the FOREARM.]
Arnold-Chiari Malformation	D001139	[A group of congenital malformations involving the brainstem, cerebellum, upper spinal cord, and surrounding bony structures. Type II is the most common, and features compression of the medulla and cerebellar tonsils into the upper cervical spinal canal and an associated MENINGOMYELOCELE. Type I features similar, but less severe malformations and is without an associated meningomyelocele. Type III has the features of type II with an additional herniation of the entire cerebellum through the bony defect involving the foramen magnum, forming an ENCEPHALOCELE. Type IV is a form a cerebellar hypoplasia. Clinical manifestations of types I-III include TORTICOLLIS; opisthotonus; HEADACHE; VERTIGO; VOCAL CORD PARALYSIS; APNEA; NYSTAGMUS, CONGENITAL; swallowing difficulties; and ATAXIA. (From Menkes, Textbook of Child Neurology, 5th ed, p261; Davis, Textbook of Neuropathology, 2nd ed, pp236-46)]
Arrhythmia, Sinus	D001146	[Irregular HEART RATE caused by abnormal function of the SINOATRIAL NODE. It is characterized by a greater than 10% change between the maximum and the minimum sinus cycle length or 120 milliseconds.]
Arrhythmias, Cardiac	D001145	[Any disturbances of the normal rhythmic beating of the heart or MYOCARDIAL CONTRACTION. Cardiac arrhythmias can be classified by the abnormalities in HEART RATE, disorders of electrical impulse generation, or impulse conduction.]
Arrhythmogenic Right Ventricular Dysplasia	D019571	[A congenital cardiomyopathy that is characterized by infiltration of adipose and fibrous tissue into the RIGHT VENTRICLE wall and loss of myocardial cells. Primary injuries usually are at the free wall of right ventricular and right atria resulting in ventricular and supraventricular arrhythmias.]
Arsenic Poisoning	D020261	[Disorders associated with acute or chronic exposure to compounds containing ARSENIC (ARSENICALS) which may be fatal. Acute oral ingestion is associated with gastrointestinal symptoms and an encephalopathy which may manifest as SEIZURES, mental status changes, and COMA. Chronic exposure is associated with mucosal irritation, desquamating rash, myalgias, peripheral neuropathy, and white transverse (Mees) lines in the fingernails. (Adams et al., Principles of Neurology, 6th ed, p1212)]
Arterial Occlusive Diseases	D001157	[Pathological processes which result in the partial or complete obstruction of ARTERIES. They are characterized by greatly reduced or absence of blood flow through these vessels. They are also known as arterial insufficiency.]
Arterio-Arterial Fistula	D001159	[Abnormal communication between two ARTERIES that may result from injury or occur as a congenital abnormality.]
Arteriolosclerosis	D050379	[Thickening of the walls of small ARTERIES or ARTERIOLES due to cell proliferation or HYALINE deposition.]
Arteriosclerosis	D001161	[Thickening and loss of elasticity of the walls of ARTERIES of all sizes. There are many forms classified by the types of lesions and arteries involved, such as ATHEROSCLEROSIS with fatty lesions in the ARTERIAL INTIMA of medium and large muscular arteries.]
Arteriosclerosis Obliterans	D001162	[Common occlusive arterial disease which is caused by ATHEROSCLEROSIS. It is characterized by lesions in the innermost layer (ARTERIAL INTIMA) of arteries including the AORTA and its branches to the extremities. Risk factors include smoking, HYPERLIPIDEMIA, and HYPERTENSION.]
Arteriovenous Fistula	D001164	[An abnormal direct communication between an artery and a vein without passing through the CAPILLARIES. An A-V fistula usually leads to the formation of a dilated sac-like connection, arteriovenous aneurysm. The locations and size of the shunts determine the degree of effects on the cardiovascular functions such as BLOOD PRESSURE and HEART RATE.]
Arteriovenous Malformations	D001165	[Abnormal formation of blood vessels that shunt arterial blood directly into veins without passing through the CAPILLARIES. They usually are crooked, dilated, and with thick vessel walls. A common type is the congenital arteriovenous fistula. The lack of blood flow and oxygen in the capillaries can lead to tissue damage in the affected areas.]
Arteritis	D001167	[INFLAMMATION of any ARTERIES.]
Arterivirus Infections	D018174	[Infections caused by viruses of the genus ARTERIVIRUS.]
Arthralgia	D018771	[Pain in the joint.]
Arthritis	D001168	[Acute or chronic inflammation of JOINTS.]
Arthritis, Experimental	D001169	[An experimental model of arthritis that is induced by injecting COLLAGEN to stimulate the immune response., An experimental model of arthritis that is induced by injecting adjuvants. These adjuvants generally consists of a mixture of light paraffin oil, emulsifying agent, and infective agents or antigens, such as killed mycobacteria or bacterial lipopolysaccharides., ARTHRITIS that is induced in experimental animals. Immunological methods and infectious agents can be used to develop experimental arthritis models. These methods include injections of stimulators of the immune response, such as an adjuvant (ADJUVANTS, IMMUNOLOGIC) or COLLAGEN.]
Arthritis, Gouty	D015210	[Arthritis, especially of the great toe, as a result of gout. Acute gouty arthritis often is precipitated by trauma, infection, surgery, etc. The initial attacks are usually monoarticular but later attacks are often polyarticular. Acute and chronic gouty arthritis are associated with accumulation of MONOSODIUM URATE in and around affected joints.]
Arthritis, Infectious	D001170	[Arthritis caused by BACTERIA; RICKETTSIA; MYCOPLASMA; VIRUSES; FUNGI; or PARASITES.]
