Label	Id	Description
Pure Autonomic Failure	D054970	[A degenerative disease of the AUTONOMIC NERVOUS SYSTEM that is characterized by idiopathic ORTHOSTATIC HYPOTENSION and a greatly reduced level of CATECHOLAMINES. No other neurological deficits are present.]
Purine-Pyrimidine Metabolism, Inborn Errors	D011686	[Dysfunctions in the metabolism of PURINES or PYRIMIDINES resulting from inborn genetic mutations that are inherited or acquired in utero.]
Purpura	D011693	[Pinhead size (3 mm) skin discolorization due to hemorrhage., Purplish or brownish red discoloration, easily visible through the epidermis, caused by hemorrhage into the tissues. When the size of the discolorization is >2-3 cm it is generally called Ecchymoses (ECCHYMOSIS).]
Purpura Fulminans	D055665	[A severe, rapidly fatal reaction occurring most commonly in children following an infectious illness. It is characterized by large, rapidly spreading skin hemorrhages, fever, or shock. Purpura fulminans often accompanies or is triggered by DISSEMINATED INTRAVASCULAR COAGULATION.]
Purpura, Hyperglobulinemic	D011694	[Purplish or brownish red discoloration of the skin associated with increase in circulating polyclonal globulins, usually GAMMA-GLOBULINS. This syndrome often occurs on the legs of women aged 20 to 40 years.]
Purpura, Schoenlein-Henoch	D011695	[A systemic non-thrombocytopenic purpura caused by HYPERSENSITIVITY VASCULITIS and deposition of IGA-containing IMMUNE COMPLEXES within the blood vessels throughout the body, including those in the kidney (KIDNEY GLOMERULUS). Clinical symptoms include URTICARIA; ERYTHEMA; ARTHRITIS; GASTROINTESTINAL HEMORRHAGE; and renal involvement. Most cases are seen in children after acute upper respiratory infections.]
Purpura, Thrombocytopenic	D011696	[Any form of purpura in which the PLATELET COUNT is decreased. Many forms are thought to be caused by immunological mechanisms.]
Purpura, Thrombocytopenic, Idiopathic	D016553	[Thrombocytopenia occurring in the absence of toxic exposure or a disease associated with decreased platelets. It is mediated by immune mechanisms, in most cases IMMUNOGLOBULIN G autoantibodies which attach to platelets and subsequently undergo destruction by macrophages. The disease is seen in acute (affecting children) and chronic (adult) forms.]
Purpura, Thrombotic Thrombocytopenic	D011697	[An acquired, congenital, or familial disorder caused by PLATELET AGGREGATION with THROMBOSIS in terminal arterioles and capillaries. Clinical features include THROMBOCYTOPENIA; HEMOLYTIC ANEMIA; AZOTEMIA; FEVER; and thrombotic microangiopathy. The classical form also includes neurological symptoms and end-organ damage, such as RENAL FAILURE. Mutations in the ADAMTS13 PROTEIN gene have been identified in familial cases.]
Putaminal Hemorrhage	D020146	[Intracranial bleeding into the PUTAMEN, a BASAL GANGLIA nucleus. This is associated with HYPERTENSION and lipohyalinosis of small blood vessels in the putamen. Clinical manifestations vary with the size of hemorrhage, but include HEMIPARESIS; HEADACHE; and alterations of consciousness., A collection of blood in PUTAMEN.]
Pycnodysostosis	D058631	[Rare autosomal recessive syndrome characterized by delayed closing of CRANIAL SUTURES, short stature, ACRO-OSTEOLYSIS of distal phalanges, dental and MAXILLOFACIAL ABNORMALITIES and an increase in bone density that results in frequent BONE FRACTURES. It is associated with BONE RESORPTION defect due to mutations in the lysosomal cysteine protease CATHEPSIN K.]
Pyelectasis	D058536	[Dilation of fetal KIDNEY PELVIS. It is a common PRENATAL ULTRASONOGRAPHY finding with no significant long-term sequelae.]
Pyelitis	D011702	[Inflammation of the KIDNEY PELVIS and KIDNEY CALICES where urine is collected before discharge, but does not involve the renal parenchyma (the NEPHRONS) where urine is processed.]
Pyelocystitis	D053653	[Inflammation of the KIDNEY PELVIS and the URINARY BLADDER.]
Pyelonephritis	D011704	[Inflammation of the KIDNEY involving the renal parenchyma (the NEPHRONS); KIDNEY PELVIS; and KIDNEY CALICES. It is characterized by ABDOMINAL PAIN; FEVER; NAUSEA; VOMITING; and occasionally DIARRHEA.]
Pyelonephritis, Xanthogranulomatous	D011705	[A chronic inflammatory condition of the KIDNEY resulting in diffuse renal destruction, a grossly enlarged and nonfunctioning kidney associated with NEPHROLITHIASIS and KIDNEY STONES.]
Pyloric Stenosis	D011707	[Narrowing of the pyloric canal with varied etiology. A common form is due to muscle hypertrophy (PYLORIC STENOSIS, HYPERTROPHIC) seen in infants.]
Pyloric Stenosis, Hypertrophic	D046248	[Narrowing of the pyloric canal due to HYPERTROPHY of the surrounding circular muscle. It is usually seen in infants or young children.]
Pyoderma	D011711	[Any purulent skin disease (Dorland, 27th ed).]
Pyoderma Gangrenosum	D017511	[An idiopathic, rapidly evolving, and severely debilitating disease occurring most commonly in association with chronic ulcerative colitis. It is characterized by the presence of boggy, purplish ulcers with undermined borders, appearing mostly on the legs. The majority of cases are in people between 40 and 60 years old. Its etiology is unknown.]
