Label	Id	Description
Postpoliomyelitis Syndrome	D016262	[A syndrome characterized by new neuromuscular symptoms that occur at least 15 years after clinical stability has been attained in patients with a prior history of symptomatic poliomyelitis. Clinical features include new muscular weakness and atrophy of the limbs, bulbar innervated musculature, and muscles of respiration, combined with excessive fatigue, joint pain, and reduced stamina. The process is marked by slow progression and periods of stabilization. (From Ann NY Acad Sci 1995 May 25;753:68-80)]
Postthrombotic Syndrome	D054070	[A condition caused by one or more episodes of DEEP VEIN THROMBOSIS, usually the blood clots are lodged in the legs. Clinical features include EDEMA; PAIN; aching; heaviness; and MUSCLE CRAMP in the leg. When severe leg swelling leads to skin breakdown, it is called venous STASIS ULCER.]
Postural Orthostatic Tachycardia Syndrome	D054972	[A syndrome of ORTHOSTATIC INTOLERANCE combined with excessive upright TACHYCARDIA, and usually without associated ORTHOSTATIC HYPOTENSION. All variants have in common an excessively reduced venous return to the heart (central HYPOVOLEMIA) while upright.]
Potassium Deficiency	D011191	[A condition due to decreased dietary intake of potassium, as in starvation or failure to administer in intravenous solutions, or to gastrointestinal loss in diarrhea, chronic laxative abuse, vomiting, gastric suction, or bowel diversion. Severe potassium deficiency may produce muscular weakness and lead to paralysis and respiratory failure. Muscular malfunction may result in hypoventilation, paralytic ileus, hypotension, muscle twitches, tetany, and rhabomyolysis. Nephropathy from potassium deficit impairs the concentrating mechanism, producing POLYURIA and decreased maximal urinary concentrating ability with secondary POLYDIPSIA. (Merck Manual, 16th ed)]
Pott Puffy Tumor	D059369	[Infection of the FRONTAL BONE often as a complication of FRONTAL SINUSITIS or trauma to the frontal bone and skull. It is characterized by subperiosteal abscess with OSTEOMYELITIS.]
Pouchitis	D019449	[Acute INFLAMMATION in the INTESTINAL MUCOSA of the continent ileal reservoir (or pouch) in patients who have undergone ILEOSTOMY and restorative proctocolectomy (PROCTOCOLECTOMY, RESTORATIVE).]
Poult Enteritis Mortality Syndrome	D031261	[An acute, transmissible, infectious disease associated with high MORTALITY and MORBIDITY in young turkeys (poults). It is characterized by DIARRHEA; ANOREXIA; growth depression, and immune dysfunction. The cause is unknown but astroviruses (AVASTROVIRUS) and coronaviruses (CORONAVIRUS, TURKEY) have been isolated from diseased poults and are thought to cause the enteritis and increased susceptibility to bacterial infections.]
Poultry Diseases	D011201	[Diseases of birds which are raised as a source of meat or eggs for human consumption and are usually found in barnyards, hatcheries, etc. The concept is differentiated from BIRD DISEASES which is for diseases of birds not considered poultry and usually found in zoos, parks, and the wild.]
Poxviridae Infections	D011213	[Virus diseases caused by the POXVIRIDAE.]
Prader-Willi Syndrome	D011218	[An association of DIABETES MELLITUS with Prader-Willi Syndrome., An autosomal dominant disorder caused by deletion of the proximal long arm of the paternal chromosome 15 (15q11-q13) or by inheritance of both of the pair of chromosomes 15 from the mother (UNIPARENTAL DISOMY) which are imprinted (GENETIC IMPRINTING) and hence silenced. Clinical manifestations include MENTAL RETARDATION; MUSCULAR HYPOTONIA; HYPERPHAGIA; OBESITY; short stature; HYPOGONADISM; STRABISMUS; and HYPERSOMNOLENCE. (Menkes, Textbook of Child Neurology, 5th ed, p229)]
Pre-Eclampsia	D011225	[A complication of PREGNANCY, characterized by a complex of symptoms including maternal HYPERTENSION and PROTEINURIA with or without pathological EDEMA. Symptoms may range between mild and severe. Pre-eclampsia usually occurs after the 20th week of gestation, but may develop before this time in the presence of trophoblastic disease.]
Pre-Excitation Syndromes	D011226	[A group of conditions in which HEART VENTRICLE activation by the atrial impulse is faster than the normal impulse conduction from the SINOATRIAL NODE. In these pre-excitation syndromes, atrial impulses often bypass the ATRIOVENTRICULAR NODE delay and travel via ACCESSORY CONDUCTING PATHWAYS connecting the atrium directly to the BUNDLE OF HIS.]
Pre-Excitation, Mahaim-Type	D011227	[A form of ventricular pre-excitation characterized by a normal PR interval and a long QRS interval with an initial slow deflection (delta wave). In this syndrome, the atrial impulse travel to the ventricle via the MAHAIM FIBERS which connect ATRIOVENTRICULAR NODE directly to the right ventricle wall (NODOVENTRICULAR ACCESSORY PATHWAY) or to the RIGHT BUNDLE BRANCH OF HIS (nodofascicular accessory pathway).]
Precancerous Conditions	D011230	[Pathological conditions that tend eventually to become malignant.]
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.]
Precursor B-Cell Lymphoblastic Leukemia-Lymphoma	D015452	[A leukemia/lymphoma found predominately in children and adolescents and characterized by a high number of lymphoblasts and solid tumor lesions. Frequent sites involve LYMPH NODES, skin, and bones. It most commonly presents as leukemia.]
Precursor Cell Lymphoblastic Leukemia-Lymphoma	D054198	[A neoplasm characterized by abnormalities of the lymphoid cell precursors leading to excessive lymphoblasts in the marrow and other organs. It is the most common cancer in children and accounts for the vast majority of all childhood leukemias., When the disease process is confined to a mass lesion with no or minimal evidence of blood and less than 25% marrow involvement, the diagnosis is lymphoblastic lymphoma; with blood and greater than 25% marrow involvement, ALL is the appropriate term.]
Precursor T-Cell Lymphoblastic Leukemia-Lymphoma	D054218	[A leukemia/lymphoma found predominately in children and young adults and characterized LYMPHADENOPATHY and THYMUS GLAND involvement. It most frequently presents as a lymphoma, but a leukemic progression in the bone marrow is common.]
Prediabetic State	D011236	[The time period before the development of symptomatic diabetes. For example, certain risk factors can be observed in subjects who subsequently develop INSULIN RESISTANCE as in type 2 diabetes (DIABETES MELLITUS, TYPE 2).]
Pregnancy Complications	D011248	[Conditions or pathological processes associated with pregnancy. They can occur during or after pregnancy, and range from minor discomforts to serious diseases that require medical interventions. They include diseases in pregnant females, and pregnancies in females with diseases.]
