All individuals in MESHD

Label	Id	Description
Persistent Fetal Circulation Syndrome	D010547	[A syndrome of persistent PULMONARY HYPERTENSION in the newborn infant (INFANT, NEWBORN) without demonstrable HEART DISEASES. This neonatal condition can be caused by severe pulmonary vasoconstriction (reactive type), hypertrophy of pulmonary arterial muscle (hypertrophic type), or abnormally developed pulmonary arterioles (hypoplastic type). The newborn patient exhibits CYANOSIS and ACIDOSIS due to the persistence of fetal circulatory pattern of right-to-left shunting of blood through a patent ductus arteriosus (DUCTUS ARTERIOSUS, PATENT) and at times a patent foramen ovale (FORAMEN OVALE, PATENT).]
Persistent Hyperplastic Primary Vitreous	D054514	[A developmental ocular anomaly in which the primary VITREOUS BODY and its surrounding hyaloid vasculature failed to regress. It is usually unilateral and characterized by CATARACT; MICROPHTHALMOS (small eyeballs), and retrolenticular fibrovascular tissue. (from Yanoff: Ophthalmology, 2nd ed.)]
Persistent Vegetative State	D018458	[Vegetative state refers to the neurocognitive status of individuals with severe brain damage, in whom physiologic functions (sleep-wake cycles, autonomic control, and breathing) persist, but awareness (including all cognitive function and emotion) is abolished.]
Peste-des-Petits-Ruminants	D029021	[A highly fatal contagious disease of goats and sheep caused by PESTE-DES-PETITS-RUMINANTS VIRUS. The disease may be acute or subacute and is characterized by stomatitis, conjunctivitis, diarrhea, and pneumonia.]
Pestivirus Infections	D018182	[Infections with viruses of the genus PESTIVIRUS, family FLAVIVIRIDAE.]
Petrositis	D059270	[Inflammation of PETROUS BONE., Inflammation of PETROUS BONE secondary to chronic OTITIS MEDIA. Its symptoms include fever, occipital headache, ear and retroorbital pain, and facial paralysis.]
Peutz-Jeghers Syndrome	D010580	[A hereditary disease caused by autosomal dominant mutations involving CHROMOSOME 19. It is characterized by the presence of INTESTINAL POLYPS, consistently in the JEJUNUM, and mucocutaneous pigmentation with MELANIN spots of the lips, buccal MUCOSA, and digits.]
Phaeohyphomycosis	D060446	[OPPORTUNISTIC INFECTIONS caused by the dematiaceous (darkly pigmented) MITOSPORIC FUNGI of ALTERNARIA, Bipolaris, CLADOSPORIUM, Curvularia, and EXOPHIALA. These fungi have pigmented HYPHAE due to MELANIN in the cell wall. The initial subcutaneous cyst from the infection can become systemic and spread rapidly to renal, pulmonary and cerebral systems (see CEREBRAL PHAEOHYPHOMYCOSIS) in an IMMUNOCOMPROMISED HOST.]
Phagocyte Bactericidal Dysfunction	D010585	[Disorders in which phagocytic cells cannot kill ingested bacteria; characterized by frequent recurring infection with formulation of granulomas.]
Phantom Limb	D010591	[Perception of painful and nonpainful phantom sensations that occur following the complete or partial loss of a limb. The majority of individuals with an amputated extremity will experience the impression that the limb is still present, and in many cases, painful. (From Neurol Clin 1998 Nov;16(4):919-36; Brain 1998 Sep;121(Pt 9):1603-30)]
Pharyngeal Diseases	D010608	[Pathological processes involving the PHARYNX.]
Pharyngeal Neoplasms	D010610	[Tumors or cancer of the PHARYNX.]
Pharyngitis	D010612	[Inflammation of the throat (PHARYNX).]
Phencyclidine Abuse	D010623	[The misuse of phencyclidine with associated psychological symptoms and impairment in social or occupational functioning.]
Phenylketonuria, Maternal	D017042	[A condition occurring in untreated or partially treated females with PHENYLKETONURIA when they become pregnant. This may result in damages to the FETUS, including MICROCEPHALY; MENTAL RETARDATION; congenital heart disease; FETAL GROWTH RETARDATION; and CRANIOFACIAL ABNORMALITIES. (From Am J Med Genet 1997 Mar 3;69(1):89-95)]
Phenylketonurias	D010661	[A group of autosomal recessive disorders marked by a deficiency of the hepatic enzyme PHENYLALANINE HYDROXYLASE or less frequently by reduced activity of DIHYDROPTERIDINE REDUCTASE (i.e., atypical phenylketonuria). Classical phenylketonuria is caused by a severe deficiency of phenylalanine hydroxylase and presents in infancy with developmental delay; SEIZURES; skin HYPOPIGMENTATION; ECZEMA; and demyelination in the central nervous system. (From Adams et al., Principles of Neurology, 6th ed, p952).]
Pheochromocytoma	D010673	[A usually benign, well-encapsulated, lobular, vascular tumor of chromaffin tissue of the ADRENAL MEDULLA or sympathetic paraganglia. The cardinal symptom, reflecting the increased secretion of EPINEPHRINE and NOREPINEPHRINE, is HYPERTENSION, which may be persistent or intermittent. During severe attacks, there may be HEADACHE; SWEATING, palpitation, apprehension, TREMOR; PALLOR or FLUSHING of the face, NAUSEA and VOMITING, pain in the CHEST and ABDOMEN, and paresthesias of the extremities. The incidence of malignancy is as low as 5% but the pathologic distinction between benign and malignant pheochromocytomas is not clear. (Dorland, 27th ed; DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1298)]
Philadelphia Chromosome	D010677	[An aberrant form of human CHROMOSOME 22 characterized by translocation of the distal end of chromosome 9 from 9q34, to the long arm of chromosome 22 at 22q11. It is present in the bone marrow cells of 80 to 90 per cent of patients with chronic myelocytic leukemia (LEUKEMIA, MYELOGENOUS, CHRONIC, BCR-ABL POSITIVE).]
Phimosis	D010688	[A condition in which the FORESKIN cannot be retracted to reveal the GLANS PENIS. It is due to tightness or narrowing of the foreskin opening.]
Phlebitis	D010689	[Periphlebitis is inflammation of the outer coat of a vein or of tissues surrounding the vein., Inflammation of a vein, often a vein in the leg. Phlebitis associated with a blood clot is called (THROMBOPHLEBITIS).]
