Label	Id	Description
Toxemia	D014115	[A condition produced by the presence of toxins or other harmful substances in the BLOOD.]
Calculi	D002137	[An abnormal concretion occurring mostly in the urinary and biliary tracts, usually composed of mineral salts. Also called stones.]
Laryngismus	D007826	[A disorder in which the adductor muscles of the VOCAL CORDS exhibit increased activity leading to laryngeal spasm. Laryngismus causes closure of the VOCAL FOLDS and airflow obstruction during inspiration.]
Vocal Cord Dysfunction	D064706	[A disorder characterized by an intermittent abnormal VOCAL CORDS movement toward the midline during inspiration or expiration resulting in upper AIRWAY OBSTRUCTION.]
Polycythemia Vera	D011087	[A myeloproliferative disorder of unknown etiology, characterized by abnormal proliferation of all hematopoietic bone marrow elements and an absolute increase in red cell mass and total blood volume, associated frequently with splenomegaly, leukocytosis, and thrombocythemia. Hematopoiesis is also reactive in extramedullary sites (liver and spleen). In time myelofibrosis occurs.]
Polycystic Ovary Syndrome	D011085	[A complex disorder characterized by infertility, HIRSUTISM; OBESITY; and various menstrual disturbances such as OLIGOMENORRHEA; AMENORRHEA; ANOVULATION. Polycystic ovary syndrome is usually associated with bilateral enlarged ovaries studded with atretic follicles, not with cysts. The term, polycystic ovary, is misleading.]
Ovarian Cysts	D010048	[General term for CYSTS and cystic diseases of the OVARY.]
Polycythemia	D011086	[An increase in the total red cell mass of the blood. (Dorland, 27th ed)]
Laryngostenosis	D007829	[Developmental or acquired stricture or narrowing of the LARYNX. Symptoms of respiratory difficulty depend on the degree of laryngeal narrowing.]
Malaria, Vivax	D016780	[Malaria caused by PLASMODIUM VIVAX. This form of malaria is less severe than MALARIA, FALCIPARUM, but there is a higher probability for relapses to occur. Febrile paroxysms often occur every other day.]
Malaria	D008288	[A protozoan disease caused in humans by four species of the PLASMODIUM genus: PLASMODIUM FALCIPARUM; PLASMODIUM VIVAX; PLASMODIUM OVALE; and PLASMODIUM MALARIAE; and transmitted by the bite of an infected female mosquito of the genus ANOPHELES. Malaria is endemic in parts of Asia, Africa, Central and South America, Oceania, and certain Caribbean islands. It is characterized by extreme exhaustion associated with paroxysms of high FEVER; SWEATING; shaking CHILLS; and ANEMIA. Malaria in ANIMALS is caused by other species of plasmodia.]
Ciliophora Infections	D016770	[Infections with protozoa of the phylum CILIOPHORA.]
Leprosy, Lepromatous	D015440	[A chronic communicable infection which is a principal or polar form of LEPROSY. This disorder is caused by MYCOBACTERIUM LEPRAE and produces diffuse granulomatous skin lesions in the form of nodules, macules, or papules. The peripheral nerves are involved symmetrically and neural sequelae occur in the advanced stage.]
Leprosy, Tuberculoid	D015441	[A principal or polar form of LEPROSY in which the skin lesions are few and are sharply demarcated. Peripheral nerve involvement is pronounced and may be severe. Unlike lepromatous leprosy (LEPROSY, LEPROMATOUS), the lepromin test is positive. Tuberculoid leprosy is rarely a source of infection to others.]
Leishmaniasis, Cutaneous	D016773	[An endemic disease that is characterized by the development of single or multiple localized lesions on exposed areas of skin that typically ulcerate. The disease has been divided into Old and New World forms. Old World leishmaniasis is separated into three distinct types according to epidemiology and clinical manifestations and is caused by species of the L. tropica and L. aethiopica complexes as well as by species of the L. major genus. New World leishmaniasis, also called American leishmaniasis, occurs in South and Central America and is caused by species of the L. mexicana or L. braziliensis complexes.]
Leishmaniasis	D007896	[A disease caused by any of a number of species of protozoa in the genus LEISHMANIA. There are four major clinical types of this infection: cutaneous (Old and New World) (LEISHMANIASIS, CUTANEOUS), diffuse cutaneous (LEISHMANIASIS, DIFFUSE CUTANEOUS), mucocutaneous (LEISHMANIASIS, MUCOCUTANEOUS), and visceral (LEISHMANIASIS, VISCERAL).]
Leishmaniasis, Diffuse Cutaneous	D016774	[A form of LEISHMANIASIS, CUTANEOUS caused by Leishmania aethiopica in Ethiopia and Kenya, L. pifanoi in Venezuela, L. braziliensis in South America, and L. mexicana in Central America. This disease is characterized by massive dissemination of skin lesions without visceral involvement.]
Blastocystis Infections	D016776	[Infections with organisms of the genus BLASTOCYSTIS. The species B. hominis is responsible for most infections. Parasitologic surveys have generally found small numbers of this species in human stools, but higher positivity rates and organism numbers in AIDS patients and other immunosuppressed patients (IMMUNOCOMPROMISED HOST). Symptoms include ABDOMINAL PAIN; DIARRHEA; CONSTIPATION; VOMITING; and FATIGUE.]
Malaria, Cerebral	D016779	[A condition characterized by somnolence or coma in the presence of an acute infection with PLASMODIUM FALCIPARUM (and rarely other Plasmodium species). Initial clinical manifestations include HEADACHES; SEIZURES; and alterations of mentation followed by a rapid progression to COMA. Pathologic features include cerebral capillaries filled with parasitized erythrocytes and multiple small foci of cortical and subcortical necrosis. (From Adams et al., Principles of Neurology, 6th ed, p136)]
Central Nervous System Protozoal Infections	D020808	[Infections of the brain, spinal cord, or meninges by single celled organisms of the former subkingdom known as protozoa. The central nervous system may be the primary or secondary site of protozoal infection. These diseases may occur as OPPORTUNISTIC INFECTIONS or arise in immunocompetent hosts.]
