Label	Id	Description
Macroglossia	D008260	[The presence of an excessively large tongue, which may be congenital or may develop as a result of a tumor or edema due to obstruction of lymphatic vessels, or it may occur in association with hyperpituitarism or acromegaly. It also may be associated with malocclusion because of pressure of the tongue on the teeth. (From Jablonski, Dictionary of Dentistry, 1992)]
Macrostomia	D008265	[Greatly exaggerated width of the mouth, resulting from failure of union of the maxillary and mandibular processes, with extension of the oral orifice toward the ear. The defect may be unilateral or bilateral. (Dorland, 27th ed)]
Tachycardia, Supraventricular	D013617	[A generic expression for any tachycardia that originates above the BUNDLE OF HIS.]
Wounds, Gunshot	D014948	[Disruption of structural continuity of the body as a result of the discharge of firearms.]
Tachycardia, Sinus	D013616	[Simple rapid heartbeats caused by rapid discharge of impulses from the SINOATRIAL NODE, usually between 100 and 180 beats/min in adults. It is characterized by a gradual onset and termination. Sinus tachycardia is common in infants, young children, and adults during strenuous physical activities.]
Catheter-Related Infections	D055499	[Infections resulting from the use of catheters. Proper aseptic technique, site of catheter placement, material composition, and virulence of the organism are all factors that can influence possible infection.]
Macular Edema	D008269	[Fluid accumulation in the outer layer of the MACULA LUTEA that results from intraocular or systemic insults. It may develop in a diffuse pattern where the macula appears thickened or it may acquire the characteristic petaloid appearance referred to as cystoid macular edema. Although macular edema may be associated with various underlying conditions, it is most commonly seen following intraocular surgery, venous occlusive disease, DIABETIC RETINOPATHY, and posterior segment inflammatory disease. (From Survey of Ophthalmology 2004; 49(5) 470-90), Fluid accumulation in the outer layer of the MACULA LUTEA at the center of the RETINA in a petaloid pattern where cystic spaces are formed and may lead to macular depressions or holes.]
Macular Degeneration	D008268	[Degenerative changes in the RETINA usually of older adults which results in a loss of vision in the center of the visual field (the MACULA LUTEA) because of damage to the retina. It occurs in dry and wet forms.]
Wound Infection	D014946	[Invasion of a wound by pathogenic microorganisms.]
Tachycardia, Sinoatrial Nodal Reentry	D013615	[Abnormally rapid heartbeats caused by reentry circuit in or around the SINOATRIAL NODE. It is characterized by sudden onset and offset episodes of tachycardia with a HEART RATE of 100-150 beats per minute. The P wave is identical to the sinus P wave but with a longer PR interval.]
Tachycardia, Reciprocating	D054139	[Abnormally rapid heartbeats caused by reentrant conduction over the accessory pathways between the HEART ATRIA and the HEART VENTRICLES. The impulse can also travel in the reverse direction, as in some cases, atrial impulses travel to the ventricles over the accessory pathways and back to the atria over the BUNDLE OF HIS and the ATRIOVENTRICULAR NODE.]
Tachycardia, Paroxysmal	D013614	[Abnormally rapid heartbeats with sudden onset and cessation.]
Tachycardia, Ectopic Junctional	D013613	[A rare form of supraventricular tachycardia caused by automatic, not reentrant, conduction initiated from sites at the atrioventricular junction, but not the ATRIOVENTRICULAR NODE. It usually occurs during myocardial infarction, after heart surgery, or in digitalis intoxication with a HEART RATE ranging from 140 to 250 beats per minute.]
Single Umbilical Artery	D058529	[Congenital abnormality where one, instead of the usual two, UMBILICAL ARTERY connects the fetus to the placenta.]
Tachycardia, Ectopic Atrial	D013612	[Abnormally rapid heartbeats originating from one or more automatic foci (nonsinus pacemakers) in the HEART ATRIUM but away from the SINOATRIAL NODE. Unlike the reentry mechanism, automatic tachycardia speeds up and slows down gradually. The episode is characterized by a HEART RATE between 135 to less than 200 beats per minute and lasting 30 seconds or longer.]
Tachycardia, Atrioventricular Nodal Reentry	D013611	[Abnormally rapid heartbeats caused by reentry of atrial impulse into the dual (fast and slow) pathways of ATRIOVENTRICULAR NODE. The common type involves a blocked atrial impulse in the slow pathway which reenters the fast pathway in a retrograde direction and simultaneously conducts to the atria and the ventricles leading to rapid HEART RATE of 150-250 beats per minute.]
Phagocyte Bactericidal Dysfunction	D010585	[Disorders in which phagocytic cells cannot kill ingested bacteria; characterized by frequent recurring infection with formulation of granulomas.]
Enteropathy-Associated T-Cell Lymphoma	D058527	[A primary peripheral T-cell lymphoma in the gastrointestinal tract, most often in the jejunum, associated with a history of CELIAC DISEASE or other gastrointestinal diseases.]
Bezoars	D001630	[Concretions of swallowed hair, fruit or vegetable fibers, or similar substances found in the alimentary canal.]
Foreign Bodies	D005547	[Accidentally retained SURGICAL SPONGES after surgery., Inanimate objects that become enclosed in the body.]
