Label	Id	Description
Thecoma	D013798	[A gonadal stromal neoplasm composed only of THECA CELLS, occurring mostly in the postmenopausal OVARY. It is filled with lipid-containing spindle cells and produces ESTROGENS that can lead to ENDOMETRIAL HYPERPLASIA; UTERINE HEMORRHAGE; or other malignancies in postmenopausal women and sexual precocity in girls. When tumors containing theca cells also contain FIBROBLASTS, they are identified as thecoma-fibroma tumors with less active hormone production.]
Theileriasis	D013801	[Infection of cattle, sheep, or goats with protozoa of the genus THEILERIA. This infection results in an acute or chronic febrile condition.]
Thiamine Deficiency	D013832	[A nutritional condition produced by a deficiency of THIAMINE in the diet, characterized by anorexia, irritability, and weight loss. Later, patients experience weakness, peripheral neuropathy, headache, and tachycardia. In addition to being caused by a poor diet, thiamine deficiency in the United States most commonly occurs as a result of alcoholism, since ethanol interferes with thiamine absorption. In countries relying on polished rice as a dietary staple, BERIBERI prevalence is very high. (From Cecil Textbook of Medicine, 19th ed, p1171)]
Thinness	D013851	[A state of insufficient flesh on the body usually defined as having a body weight less than skeletal and physical standards. Depending on age, sex, and genetic background, a BODY MASS INDEX of less than 18.5 is considered as underweight.]
Thoracic Diseases	D013896	[Disorders affecting the organs of the thorax.]
Thoracic Injuries	D013898	[General or unspecified injuries to the chest area.]
Thoracic Neoplasms	D013899	[New abnormal growth of tissue in the THORAX.]
Thoracic Outlet Syndrome	D013901	[A neurovascular syndrome associated with compression of the BRACHIAL PLEXUS; SUBCLAVIAN ARTERY; and SUBCLAVIAN VEIN at the superior thoracic outlet. This may result from a variety of anomalies such as a CERVICAL RIB, anomalous fascial bands, and abnormalities of the origin or insertion of the anterior or medial scalene muscles. Clinical features may include pain in the shoulder and neck region which radiates into the arm, PARESIS or PARALYSIS of brachial plexus innervated muscles, PARESTHESIA, loss of sensation, reduction of arterial pulses in the affected extremity, ISCHEMIA, and EDEMA. (Adams et al., Principles of Neurology, 6th ed, pp214-5).]
Thrombasthenia	D013915	[A congenital bleeding disorder with prolonged bleeding time, absence of aggregation of platelets in response to most agents, especially ADP, and impaired or absent clot retraction. Platelet membranes are deficient in or have a defect in the glycoprotein IIb-IIIa complex (PLATELET GLYCOPROTEIN GPIIB-IIIA COMPLEX).]
Thromboangiitis Obliterans	D013919	[A non-atherosclerotic, inflammatory thrombotic disease that commonly involves small and medium-sized arteries or veins in the extremities. It is characterized by occlusive THROMBOSIS and FIBROSIS in the vascular wall leading to digital and limb ISCHEMIA and ulcerations. Thromboangiitis obliterans is highly associated with tobacco smoking.]
Thrombocythemia, Essential	D013920	[A clinical syndrome characterized by repeated spontaneous hemorrhages and a remarkable increase in the number of circulating platelets.]
Thrombocytopenia	D013921	[A subnormal level of BLOOD PLATELETS.]
Thrombocytopenia, Neonatal Alloimmune	D054098	[A condition in newborns caused by immunity of the mother to PLATELET ALLOANTIGENS on the fetal platelets. The PLATELETS, coated with maternal ANTIBODIES, are destroyed and removed by the fetal MONONUCLEAR PHAGOCYTE SYSTEM. Affected infants may have INTRACRANIAL HEMORRHAGES.]
Thrombocytosis	D013922	[Increased numbers of platelets in the peripheral blood. (Dorland, 27th ed)]
Thromboembolism	D013923	[Obstruction of a blood vessel (embolism) by a blood clot (THROMBUS) in the blood stream.]
Thrombophilia	D019851	[A disorder of HEMOSTASIS in which there is a tendency for the occurrence of THROMBOSIS.]
Thrombophlebitis	D013924	[Inflammation of a vein associated with a blood clot (THROMBUS)., Inflammation that is characterized by swollen, pale, and painful limb. It is usually caused by DEEP VEIN THROMBOSIS in a FEMORAL VEIN, following PARTURITION or an illness. This condition is also called milk leg or white leg.]
Thrombosis	D013927	[Formation and development of a thrombus or blood clot in the blood vessel.]
Thrombotic Microangiopathies	D057049	[Diseases that result in THROMBOSIS in MICROVASCULATURE. The two most prominent diseases are PURPURA, THROMBOTIC THROMBOCYTOPENIC; and HEMOLYTIC-UREMIC SYNDROME. Multiple etiological factors include VASCULAR ENDOTHELIAL CELL damage due to SHIGA TOXIN; FACTOR H deficiency; and aberrant VON WILLEBRAND FACTOR formation.]
Thymoma	D013945	[A neoplasm originating from thymic tissue, usually benign, and frequently encapsulated. Although it is occasionally invasive, metastases are extremely rare. It consists of any type of thymic epithelial cell as well as lymphocytes that are usually abundant. Malignant lymphomas that involve the thymus, e.g., lymphosarcoma, Hodgkin's disease (previously termed granulomatous thymoma), should not be regarded as thymoma. (From Stedman, 25th ed)]
