Label	Id	Description
Premenstrual Syndrome	D011293	[A term used to describe the psychological aspects of PREMENSTRUAL SYNDROME, such as the "indescribable tension", depression, hostility, and increased seizure activity in women with seizure disorder., A combination of distressing physical, psychologic, or behavioral changes that occur during the luteal phase of the menstrual cycle. Symptoms of PMS are diverse (such as pain, water-retention, anxiety, cravings, and depression) and they diminish markedly 2 or 3 days after the initiation of menses.]
Prenatal Exposure Delayed Effects	D011297	[The consequences of exposing the FETUS in utero to certain factors, such as NUTRITION PHYSIOLOGICAL PHENOMENA; PHYSIOLOGICAL STRESS; DRUGS; RADIATION; and other physical or chemical factors. These consequences are observed later in the offspring after BIRTH.]
Prenatal Injuries	D049188	[Damages to the EMBRYO, MAMMALIAN or the FETUS before BIRTH. Damages can be caused by any factors including biological, chemical, or physical.]
Presbycusis	D011304	[Gradual bilateral hearing loss associated with aging that is due to progressive degeneration of cochlear structures and central auditory pathways. Hearing loss usually begins with the high frequencies then progresses to sounds of middle and low frequencies.]
Presbyopia	D011305	[The normal decreasing elasticity of the crystalline lens that leads to loss of accommodation.]
Pressure Ulcer	D003668	[An ulceration caused by prolonged pressure on the SKIN and TISSUES when one stays in one position for a long period of time, such as lying in bed. The bony areas of the body are the most frequently affected sites which become ischemic (ISCHEMIA) under sustained and constant pressure.]
Priapism	D011317	[A prolonged painful erection that may lasts hours and is not associated with sexual activity. It is seen in patients with SICKLE CELL ANEMIA, advanced malignancy, spinal trauma; and certain drug treatments.]
Primary Dysautonomias	D054969	[Disorders of the AUTONOMIC NERVOUS SYSTEM occurring as a primary condition. Manifestations can involve any or all body systems but commonly affect the BLOOD PRESSURE and HEART RATE.]
Primary Graft Dysfunction	D055031	[A form of ischemia-reperfusion injury occurring in the early period following transplantation. Significant pathophysiological changes in MITOCHONDRIA are the main cause of the dysfunction. It is most often seen in the transplanted lung, liver, or kidney and can lead to GRAFT REJECTION.]
Primary Myelofibrosis	D055728	[A de novo myeloproliferation arising from an abnormal stem cell. It is characterized by the replacement of bone marrow by fibrous tissue, a process that is mediated by CYTOKINES arising from the abnormal clone.]
Primary Ovarian Insufficiency	D016649	[A form of ovarian failure, caused by resistance to GONADOTROPINS stimulation. It may be caused by defects in the receptors for FOLLICLE STIMULATING HORMONE or LUTEINIZING HORMONE. It may be due to factors interfering with the actions of gonadotropins, such as antibodies blocking the ligand-receptor interaction., Cessation of ovarian function after MENARCHE but before the age of 40, without or with OVARIAN FOLLICLE depletion. It is characterized by the presence of OLIGOMENORRHEA or AMENORRHEA, elevated GONADOTROPINS, and low ESTRADIOL levels. It is a state of female HYPERGONADOTROPIC HYPOGONADISM. Etiologies include genetic defects, autoimmune processes, chemotherapy, radiation, and infections. The most commonly known genetic cause is the expansion of a CGG repeat to 55 to 199 copies in the 5' untranslated region in the X-linked FMR1 gene.]
Primary Progressive Nonfluent Aphasia	D057178	[A form of frontotemporal lobar degeneration and a progressive form of dementia characterized by motor speech impairment and AGRAMMATISM, with relative sparing of single word comprehension and semantic memory.]
Primate Diseases	D018419	[Diseases of animals within the order PRIMATES. This term includes diseases of Haplorhini and Strepsirhini.]
Prion Diseases	D017096	[A group of genetic, infectious, or sporadic degenerative human and animal nervous system disorders associated with abnormal PRIONS. These diseases are characterized by conversion of the normal prion protein to an abnormal configuration via a post-translational process. In humans, these conditions generally feature DEMENTIA; ATAXIA; and a fatal outcome. Pathologic features include a spongiform encephalopathy without evidence of inflammation. The older literature occasionally refers to these as unconventional SLOW VIRUS DISEASES. (From Proc Natl Acad Sci USA 1998 Nov 10;95(23):13363-83)]
Proctitis	D011349	[INFLAMMATION of the MUCOUS MEMBRANE of the RECTUM, the distal end of the large intestine (INTESTINE, LARGE).]
Proctocolitis	D011350	[Inflammation of the RECTUM and the distal portion of the COLON.]
Prodromal Symptoms	D062706	[Clinical or physiological indicators that precede the onset of disease., Time marking early onset of disease, Early onset of symptoms, Early event in disease onset]
Progeria	D011371	[An abnormal congenital condition, associated with defects in the LAMIN TYPE A gene, which is characterized by premature aging in children, where all the changes of cell senescence occur. It is manifested by premature greying; hair loss; hearing loss (DEAFNESS); cataracts (CATARACT); ARTHRITIS; OSTEOPOROSIS; DIABETES MELLITUS; atrophy of subcutaneous fat; skeletal hypoplasia; elevated urinary HYALURONIC ACID; and accelerated ATHEROSCLEROSIS. Many affected individuals develop malignant tumors, especially SARCOMA.]
Prognathism	D011378	[A condition marked by abnormal protrusion of the mandible. (Dorland, 27th ed)]
Prolactinoma	D015175	[A pituitary adenoma which secretes PROLACTIN, leading to HYPERPROLACTINEMIA. Clinical manifestations include AMENORRHEA; GALACTORRHEA; IMPOTENCE; HEADACHE; visual disturbances; and CEREBROSPINAL FLUID RHINORRHEA.]
