31
Q

infiltrating ductal carcinoma

A

Infiltrating ductal carcinoma starts in the milk duct, breaks through the wall of that duct, and invades the fatty breast tissue. This form of cancer accounts for the majority of all breast cancers. Infiltrating and invasive are terms used to describe cancer that has spread beyond the layer of tissue in which it developed and is now growing into surrounding, healthy tissues. Also known as invasive ductal carcinoma.

32
Q

infiltrating lobular carcinoma

Infiltrating lobular carcinoma is cancer that starts in the milk glands (lobules), breaks through the wall of the gland, and invades the fatty tissue of the breast. Once this cancer reaches the lymph nodes, it can rapidly spread to distant parts of the body. Also known as invasive lobular carcinoma.

33
Q

inflammation

A

A localized response to an injury or to the destruction of tissues. The key indicators of inflammation are (1) erythema (redness), (2) hyperthermia (heat), (3) edema (swelling), and (4) pain. These are caused by extra blood flowing into the area as part of the healing process

34
Q

inflammatory bowel disease (IBD)

A

The general name for diseases that cause inflammation and swelling in the intestines. The two most common inflammatory bowel diseases are ulcerative colitis and Crohn?s disease. These conditions are grouped together because both are chronic and incurable, and can affect the large and small intestines. They also have similar symptoms, which include abdominal pain, weight loss, fatigue, fever, rectal bleeding, and diarrhea. These conditions tend to occur at intervals of active disease known as flares alternating with periods of remission. Flares of these disorders are treated with medication and surgery to remove diseased portions of the intestine.

35
Q

inflammatory breast cancer (IBC)

A

A rare but aggressive form of breast cancer. IBC grows rapidly, and the symptoms include pain, rapid increase in the breast size, redness or a rash on the breast, and swelling of nearby lymph nodes. Most breast cancers are detected by mammography, ultrasound, or self-examination. In contrast, IBC can be detected only by magnetic resonance imaging (MRI).

36
Q

influenza

A

An acute, highly contagious viral infection characterized by respiratory inflammation, fever, chills, and muscle pain. Influenza is spread by respiratory droplets and occurs most commonly in epidemics during the colder months. There are many strains of the influenza virus. Some strains can be prevented by annual immunization. Also known as the flu.

37
Q

40
Q

insulinoma

A

A benign tumor of the pancreas that causes hypoglycemia by secreting additional insulin.

41

44
Q

intermittent claudication

A

Intermittent claudication is pain in the leg muscles that occurs during exercise and is relieved by rest. Intermittent means coming and going at intervals, and claudication means limping. This condition, which is due to poor circulation, is associated with peripheral vascular disease.

45
Q

internal fixation

Internal fixation is a fracture treatment in which a plate or pins are placed directly into the bone to hold the broken pieces in place. This form of fixation is not usually removed after the fracture has healed. Also known as open reduction internal fixation (ORIF).

46
Q

interstitial cystitis

A

A chronic inflammation within the walls of the bladder. The symptoms of this condition are similar to those of cystitis; however, they do not respond to traditional treatment. Interstitial means relating to spaces within a tissue or organ.

47
Q

interstitial lung diseases

A

Interstitial lung disease refers to a group of almost 200 disorders that cause inflammation and scarring of the alveoli and their supporting structures. Interstitial means relating to spaces within or around a tissue or an organ. In these lung conditions the tissue around the alveoli becomes scarred or stiff, leading to a reduction of oxygen being transferred to the blood.

48
Q

interventional radiology

A

The use of radiographic imaging to guide a procedure such as a biopsy. It is also used to confirm the placement of an inserted object such as a stent or feeding tube.

49
Q

intestinal obstruction

A

The partial or complete blockage of the small or large intestine caused by a physical obstruction. This blockage can result from many causes such as scar tissue or a tumor.

50
Q

intracranial pressure

A

The amount of pressure inside the skull. Elevated intracranial pressure can be due to a tumor, an injury, or improper drainage of cerebrospinal fluid.

51
Q

intradermal injection

A

An intradermal injection is made into the middle layers of the skin.

52
Q

intramuscular injection (IM)

A

intravenous pyelogram (IVP)

A

A radiographic study of the kidneys and ureters. A contrast medium is administered intravenously to clearly define these structures in the resulting image. This examination is used to diagnose changes in the urinary tract resulting from nephroliths, infections, enlarged prostate, tumors, and internal injuries after an abdominal trauma. Also known as excretory urography.

59
Q

intussusception

A

The telescoping of one part of the small intestine into the opening of an immediately adjacent part. This rare but serious condition is sometimes found in children between three months and six years of age.

60
Q

in vitro fertilization

A

A procedure in which mature ova are removed from the mother to be fertilized. The resulting embryos are transferred into the uterus with the hope that they will implant and continue to develop as in a normal pregnancy. In vitro means in an artificial environment such as a test tube.

Q

iridectomy

A

The surgical removal of a portion of the tissue of the iris. This procedure is most frequently performed to treat closed-angle glaucoma.

65
Q

irritable bowel syndrome (IBS)

A

A common condition of unknown cause with symptoms that can include intermittent cramping, abdominal pain, bloating, constipation, and diarrhea. This condition, which is usually aggravated by stress and by eating certain foods, is not caused by pathogens (bacteria or viruses) or by structural changes. Also known as spastic colon.

66
Q

ischemia

A

A condition in which there is an insufficient supply of oxygen in the tissues due to a restricted blood flow to a part of the body. For example, cardiac ischemia is the lack of blood flow and oxygen to the heart muscle.

67
Q

ischemic colitis

A

Ischemic colitis occurs when part of the large intestine is partially or completely deprived of blood. If this lack of blood lasts for more than a day, this shortage of blood leads to inflammation or permanent damage of the affected area.

68
Q

ischemic heart disease

A

A group of cardiac disabilities resulting from an insufficient supply of oxygenated blood to the heart. These diseases are usually associated with coronary artery disease. Ischemic means pertaining to the disruption of the blood supply.

69
Q

ischemic stroke

A

An ischemic stroke, which is the most common type of stroke in older people, occurs when the flow of blood to the brain is blocked by the narrowing or blockage of a carotid artery. Ischemic means pertaining to the disruption of the blood supply. One type of ischemic stroke is a thrombotic stroke, which occurs when a blood clot forms in a carotid artery and blocks it. The other is an embolic stroke, which occurs when a blood clot or other debris forms in a blood vessel somewhere other than the brain and travels through the bloodstream to lodge in the narrower brain arteries.
