Label	Id	Description
Abortion, Threatened	D000033	[UTERINE BLEEDING from a GESTATION of less than 20 weeks without any CERVICAL DILATATION. It is characterized by vaginal bleeding, lower back discomfort, or midline pelvic cramping and a risk factor for MISCARRIAGE.]
Lingual Thyroid	D046151	[A condition characterized by the presence of rudimentary THYROID tissue at the base of the TONGUE. It is due to failed embryonic development and migration of thyroid tissue to its normal location. The lingual thyroid usually cannot maintain adequate hormone production thereby resulting in HYPOTHYROIDISM.]
Thyroid Dysgenesis	D050033	[Defective development of the THYROID GLAND. This concept includes thyroid agenesis (aplasia), hypoplasia, or an ectopic gland. Clinical signs usually are those of CONGENITAL HYPOTHYROIDISM.]
Gestational Trophoblastic Disease	D031901	[A group of diseases arising from pregnancy that are commonly associated with hyperplasia of trophoblasts (TROPHOBLAST) and markedly elevated human CHORIONIC GONADOTROPIN. They include HYDATIDIFORM MOLE, invasive mole (HYDATIDIFORM MOLE, INVASIVE), placental-site trophoblastic tumor (TROPHOBLASTIC TUMOR, PLACENTAL SITE), and CHORIOCARCINOMA. These neoplasms have varying propensities for invasion and spread., Gestational Trophoblastic diseases that are malignant. It does not include HYDATIDIFORM MOLE. However, there is a minority of authors that consider the term gestational trophoblastic neoplasia synonymous with gestational trophoblastic disease.]
Preconception Injuries	D047489	[Damages to reproductive health prior to conception (FERTILIZATION), a legal term for torts liability concerning environmental safety issues. Preconception injuries may involve either the male or the female, such as chromosomal mutations in the OVA or the SPERMATOZOA.]
Disorders of Environmental Origin	D007280	[Disorders caused by external forces rather than by physiologic dysfunction or by pathogens.]
Abortion, Septic	D000031	[Any type of abortion, induced or spontaneous, that is associated with infection of the UTERUS and its appendages. It is characterized by FEVER, uterine tenderness, and foul discharge.]
Abortion, Missed	D000030	[The retention in the UTERUS of a dead FETUS two months or more after its DEATH.]
Atrial Fibrillation	D001281	[Abnormal cardiac rhythm that is characterized by rapid, uncoordinated firing of electrical impulses in the upper chambers of the heart (HEART ATRIA). In such case, blood cannot be effectively pumped into the lower chambers of the heart (HEART VENTRICLES). It is caused by abnormal impulse generation.]
Hypersplenism	D006971	[Condition characterized by splenomegaly, some reduction in the number of circulating blood cells in the presence of a normal or hyperactive bone marrow, and the potential for reversal by splenectomy.]
Atrial Flutter	D001282	[Rapid, irregular atrial contractions caused by a block of electrical impulse conduction in the right atrium and a reentrant wave front traveling up the inter-atrial septum and down the right atrial free wall or vice versa. Unlike ATRIAL FIBRILLATION which is caused by abnormal impulse generation, typical atrial flutter is caused by abnormal impulse conduction. As in atrial fibrillation, patients with atrial flutter cannot effectively pump blood into the lower chambers of the heart (HEART VENTRICLES).]
Hypertelorism	D006972	[Abnormal increase in the interorbital distance due to overdevelopment of the lesser wings of the sphenoid.]
Trisomy 18 Syndrome	D000073842	[A chromosome disorder associated with TRISOMY of all or part of CHROMOSOME 18. Clinical manifestations include INTRAUTERINE GROWTH RETARDATION; CLEFT PALATE; CONGENITAL HEART DEFECTS; MICROCEPHALY; MICROGNATHIA and clenched fists with overlapping fingers. Most affected fetuses do not survive to birth. Those who survive through their first year often have severe INTELLECTUAL DISABILITY.]
Double Outlet Right Ventricle	D004310	[Incomplete transposition of the great vessels in which both the AORTA and the PULMONARY ARTERY arise from the RIGHT VENTRICLE. The only outlet of the LEFT VENTRICLE is a large ventricular septal defect (VENTRICULAR SEPTAL DEFECTS or VSD). The various subtypes are classified by the location of the septal defect, such as subaortic, subpulmonary, or noncommitted., A subtype with ventricular septal defect clearly away from the semilunar valves of the AORTA and the PULMONARY ARTERY., A subtype with pulmonary ventricular septal defect.]
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.]
Fucosidosis	D005645	[An autosomal recessive lysosomal storage disease caused by a deficiency of ALPHA-L-FUCOSIDASE activity resulting in an accumulation of fucose containing SPHINGOLIPIDS; GLYCOPROTEINS, and mucopolysaccharides (GLYCOSAMINOGLYCANS) in lysosomes. The infantile form (type I) features psychomotor deterioration, MUSCLE SPASTICITY, coarse facial features, growth retardation, skeletal abnormalities, visceromegaly, SEIZURES, recurrent infections, and MACROGLOSSIA, with death occurring in the first decade of life. Juvenile fucosidosis (type II) is the more common variant and features a slowly progressive decline in neurologic function and angiokeratoma corporis diffusum. Type II survival may be through the fourth decade of life. (From Menkes, Textbook of Child Neurology, 5th ed, p87; Am J Med Genet 1991 Jan;38(1):111-31)]
Fuchs' Endothelial Dystrophy	D005642	[Disorder caused by loss of endothelium of the central cornea. It is characterized by hyaline endothelial outgrowths on Descemet's membrane, epithelial blisters, reduced vision, and pain.]
Down Syndrome	D004314	[A chromosome disorder associated either with an extra chromosome 21 or an effective trisomy for chromosome 21. Clinical manifestations include hypotonia, short stature, brachycephaly, upslanting palpebral fissures, epicanthus, Brushfield spots on the iris, protruding tongue, small ears, short, broad hands, fifth finger clinodactyly, Simian crease, and moderate to severe INTELLECTUAL DISABILITY. Cardiac and gastrointestinal malformations, a marked increase in the incidence of LEUKEMIA, and the early onset of ALZHEIMER DISEASE are also associated with this condition. Pathologic features include the development of NEUROFIBRILLARY TANGLES in neurons and the deposition of AMYLOID BETA-PROTEIN, similar to the pathology of ALZHEIMER DISEASE. (Menkes, Textbook of Child Neurology, 5th ed, p213)]
Hypertension, Malignant	D006974	[A condition of markedly elevated BLOOD PRESSURE with DIASTOLIC PRESSURE usually greater than 120 mm Hg. Malignant hypertension is characterized by widespread vascular damage, PAPILLEDEMA, retinopathy, HYPERTENSIVE ENCEPHALOPATHY, and renal dysfunction.]
Dourine	D004313	[A disease of horses and donkeys caused by Trypanosoma equiperdum. The disease occurs in Africa, the Americas, and Asia.]
