Label	Id	Description
Acanthosis Nigricans	D000052	[A circumscribed melanosis consisting of a brown-pigmented, velvety verrucosity or fine papillomatosis appearing in the axillae and other body folds. It occurs in association with endocrine disorders, underlying malignancy, administration of certain drugs, or as in inherited disorder.]
Acatalasia	D020642	[A rare autosomal recessive disorder resulting from the absence of CATALASE activity. Though usually asymptomatic, a syndrome of oral ulcerations and gangrene may be present.]
Accelerated Idioventricular Rhythm	D016170	[A type of automatic, not reentrant, ectopic ventricular rhythm with episodes lasting from a few seconds to a minute which usually occurs in patients with acute myocardial infarction or with DIGITALIS toxicity. The ventricular rate is faster than normal but slower than tachycardia, with an upper limit of 100 -120 beats per minute. Suppressive therapy is rarely necessary.]
Accessory Atrioventricular Bundle	D058606	[Extra impulse-conducting tissue in the heart that creates abnormal impulse-conducting connections between HEART ATRIA and HEART VENTRICLES.]
Accessory Nerve Diseases	D020436	[Diseases of the eleventh cranial (spinal accessory) nerve. This nerve originates from motor neurons in the lower medulla (accessory portion of nerve) and upper spinal cord (spinal portion of nerve). The two components of the nerve join and exit the skull via the jugular foramen, innervating the sternocleidomastoid and trapezius muscles, which become weak or paralyzed if the nerve is injured. The nerve is commonly involved in MOTOR NEURON DISEASE, and may be injured by trauma to the posterior triangle of the neck.]
Accessory Nerve Injuries	D061227	[Traumatic injuries to the ACCESSORY NERVE. Damage to the nerve may produce weakness in head rotation and shoulder elevation.]
Achlorhydria	D000126	[A lack of HYDROCHLORIC ACID in GASTRIC JUICE despite stimulation of gastric secretion.]
Achondroplasia	D000130	[An autosomal dominant disorder that is the most frequent form of short-limb dwarfism. Affected individuals exhibit short stature caused by rhizomelic shortening of the limbs, characteristic facies with frontal bossing and mid-face hypoplasia, exaggerated lumbar lordosis, limitation of elbow extension, GENU VARUM, and trident hand. (Online Mendelian Inheritance in Man, http://www.ncbi.nlm.nih.gov/Omim, MIM#100800, April 20, 2001)]
Acid-Base Imbalance	D000137	[Disturbances in the ACID-BASE EQUILIBRIUM of the body.]
Acidosis	D000138	[A pathologic condition of acid accumulation or depletion of base in the body. The two main types are RESPIRATORY ACIDOSIS and metabolic acidosis, due to metabolic acid build up.]
Acidosis, Lactic	D000140	[Acidosis caused by accumulation of lactic acid more rapidly than it can be metabolized. It may occur spontaneously or in association with diseases such as DIABETES MELLITUS; LEUKEMIA; or LIVER FAILURE.]
Acidosis, Renal Tubular	D000141	[The genetic defect is in the anion exchange protein gene SLC4A1 resulting in impaired excretion of hydrogen ions or renal acids in the distal renal tubules., The genetic defect is in the sodium bicarbonate cotransporter gene SLC4A4 resulting in impaired reabsorption of bicarbonate ions in the proximal renal tubules and bicarbonate-wasting., A group of genetic disorders of the KIDNEY TUBULES characterized by the accumulation of metabolically produced acids with elevated plasma chloride, hyperchloremic metabolic ACIDOSIS. Defective renal acidification of URINE (proximal tubules) or low renal acid excretion (distal tubules) can lead to complications such as HYPOKALEMIA, hypercalcinuria with NEPHROLITHIASIS and NEPHROCALCINOSIS, and RICKETS.]
Acidosis, Respiratory	D000142	[Respiratory retention of carbon dioxide. It may be chronic or acute.]
Acinetobacter Infections	D000151	[Infections with bacteria of the genus ACINETOBACTER.]
Acne Conglobata	D000069316	[Severe and chronic form of acne characterized by large, burrowing abscesses associated with disfigurement.]
Acne Keloid	D000153	[A type of acneiform disorder in which secondary pyogenic infection in and around pilosebaceous structures ends in keloidal scarring. It manifests as persistent folliculitis of the back of the neck associated with occlusion of the follicular orifices. It is most often encountered in black or Asian men.]
Acne Vulgaris	D000152	[A chronic disorder of the pilosebaceous apparatus associated with an increase in sebum secretion. It is characterized by open comedones (blackheads), closed comedones (whiteheads), and pustular nodules. The cause is unknown, but heredity and age are predisposing factors.]
Acneiform Eruptions	D017486	[Visible efflorescent lesions of the skin caused by acne or resembling acne. (Dorland, 28th ed, p18, 575)]
Acquired Hyperostosis Syndrome	D020083	[Syndrome consisting of SYNOVITIS; ACNE CONGLOBATA; PALMOPLANTAR PUSTULOSIS; HYPEROSTOSIS; and OSTEITIS. The most common site of the disease is the upper anterior chest wall, characterized by predominantly osteosclerotic lesions, hyperostosis, and arthritis of the adjacent joints. The association of sterile inflammatory bone lesions and neutrophilic skin eruptions is indicative of this syndrome.]
Acquired Immunodeficiency Syndrome	D000163	[An acquired defect of cellular immunity associated with infection by the human immunodeficiency virus (HIV), a CD4-positive T-lymphocyte count under 200 cells/microliter or less than 14% of total lymphocytes, and increased susceptibility to opportunistic infections and malignant neoplasms. Clinical manifestations also include emaciation (wasting) and dementia. These elements reflect criteria for AIDS as defined by the CDC in 1993.]
