Polyposis The presence of many polyps.
RELATED TERMS--------------------------------------
Polyps
An abnormal growth of a mucous membrane, often in the nasal passages, bladder, rectum, or uterus. Polyps, though often benign, have been associated with cancers and can be surgically removed.

Polyclonal activator
A substance that induces activation of many individual clones of either T or B cells. See Mitogen.
Polycystic Kidney Disease
A rare inherited condition in which the kidney are composed of multiple cysts. Kidney cysts are associated with an increased incidence of cerebral aneurysm. Symptoms usually appear later (if they do at all) and include blood in the urine, flank pain, excessive urination at night and abdominal pain. Individuals may also have elevated blood pressure. Chronic (end-stage renal disease) renal failure is the most common result in the 5th to 6th decades of life.
Polycystic Ovarian Syndrome
PCOS is a disorder in which the ovaries produce excessive amounts of male hormones (androgens) and develop many small cysts. Symptoms commonly include heavy, irregular or missed periods as well as acne, excessive hair growth on the face, obesity and infertility.
Polycystic ovary syndrome
Clinical symptom complex characterized by oligomenorrhea or amenorrhea, anovulation, and regularly associated with bilateral polycystic ovaries.
Polycystic Ovary Syndrome (PCOS)
A syndrome associated with bilateral polycystic ovaries and insulin resistance. Symptoms frequently include decreased menstrual flow, irregular menses, anovulation, and infertility.
Polycythemia
Abnormal increase in the number of red blood cells or hematocrit.
Polycythemia vera
Polycythemia vera is an abnormal increase in blood cells (primarily red blood cells) resulting from excess production by the bone marrow.
Polydactyly
Extra fingers or toes.
Polydipsia
Excessive thirst.
Polyhidrosis
Excessive sweating.
Polyiterophilia
A form of hyperphilia in which a person's own erotosexual responsiveness is built up toward orgasm by reiterating the same activity (manual, oral, anal, vaginal, or penile) many times with many partners.
Polymerase chain reaction
An in vitro method for enzymatically synthesizing and amplifying defined sequences of DNA in molecular biology. Can be used for improving DNA-based diagnostic procedures for identifying unknown BW agents.
Polymerase Chain Reaction (PCR)
PCR. A method for amplifying a DNA base sequence using a heat-stable polymerase and two 20-base primers, one complementary to the (+) strand at one end of the sequence to be amplified and one complementary to the (-) strand at the other end. Because the newly synthesized DNA strands can subsequently serve as additional templates for the same primer sequences, successive rounds of primer annealing, strand elongation, and dissociation produce rapid and highly specific amplification of the desired sequence. PCR also can be used to detect the existence of the defined sequence in a DNA sample.
Polymorphism
Literally, "having many shapes"; in genetics polymorphism means occurring in more than one form within a species; the existence of multiple alleles at a particular genetic locus.
Polymorphonuclear
Having nuclei of varied forms; denoting a variety of leukocyte.
Polymorphonuclear leukocyte
White cell, granular cytoplasm. Neutral staining (neutrophil) - most frequent, phagocytic. Basophilic staining - basophil q.v. Eosinophilic staining - eosinophil q.v.
Polymox
Polymox is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries. Active ingredient(s): amoxicillin.
Polymyalgia rheumatica
Causes limb girdle pain and stiffness. Associated with a high ESR (usually > 40mm/h) and there may be giant cell arteritis in some patients. Mainly affects those of over 60 years of age.
Polymyositis
Inflammatory muscle disease (a connective tissue disease).
Polymyxin b sulfate
Polymyxin b sulfate is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries. Active ingredient(s): polymyxin b sulfate.
Polynucleotides
Long chains of nucleotides formed by chemical links between the sugar and phosphate groups.
Polyp
A growth that projects from the lining of mucous membrane, such as the intestine.
Polypectomy
Surgical removal of a polyp.
Polyphagia
Excessive hunger; may be a symptom of uncontrolled diabetes.
Polypoid
Resembling a polyp.
Polyps
An abnormal growth of a mucous membrane, often in the nasal passages, bladder, rectum, or uterus. Polyps, though often benign, have been associated with cancers and can be surgically removed.
Polysporin
Polysporin is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries. Active ingredient(s): bacitracin zinc; polymyxin b sulfate.

Porphyria
A group of rare, inherited blood disorders. When a person has porphyria, cells fail to change chemicals (porphyrins) to the substance (heme) that gives blood its color. Porphyrins then build up in the body. They show up in large amounts in stool and urine, causing the urine to be colored blue. They cause a number of problems, including strange behavior.
Portal hypertension

Portal vein
The large vein that carries blood from the intestines and spleen to the liver.
Portosystemic shunt
An operation to create an opening between the portal vein and other veins around the liver. Can also be accessed via the jugular vein in angiography. Known as T.I.P.S.
