Topics about Medical Conditions

ACTINOMYCOSIS
Actinomycosis is an infection primarily caused by the bacterium Actinomyces israelii. Infection most often occurs in the face and neck region and is characterized by the presence of a slowly enlarging, hard, red lump.

ACUTE KIDNEY FAILURE
Acute kidney failure occurs when illness, infection, or injury damages the kidneys. Temporarily, the kidneys cannot adequately remove fluids and wastes from the body or maintain the proper level of certain kidney-regulated chemicals in the bloodstream.

ACUTE LYMPHANGITIS
Acute lymphangitis is a bacterial infection in the lymphatic vessels which is characterized by painful, red streaks below the skin surface. This is a potentially serious infection which can rapidly spread to the bloodstream and be fatal.

ACUTE POSTSTREPTOCOCCAL GLOMERULONEPHRITIS
Acute post streptococcal glomerulonephritis (APSGN) is an inflammation of the kidney tubules (glomeruli) that filter waste products from the blood, following a streptococcal infection such as strep throat. APSGN is also called post infectious glomerulonephritis.

ACUTE STRESS DISORDER
Acute stress disorder (ASD) is an anxiety disorder characterized by a cluster of dissociative and anxiety symptoms occurring within one month of a traumatic event. (Dissociation is a psychological reaction to trauma in which the mind tries to cope by "sealing off" some features of the trauma from conscious awareness).

ADDICTION
Addiction is a dependence on a behavior or substance that a person is powerless to stop. The term has been partially replaced by the word dependence for substance abuse. Addiction has been extended, however, to include mood-altering behaviors or activities. Some researchers speak of two types of addictions: substance addictions (for example, alcoholism, drug abuse, and smoking); and process addictions (for example, gambling, spending, shopping, eating, and sexual activity). There is a growing recognition that many addicts, such as polydrug abusers, are addicted to more than one substance or process.

ADDISON'S DISEASE
Addison's disease is a disorder involving disrupted functioning of the part of the adrenal gland called the cortex. These results in decreased production of two important chemicals (hormones) normally released by the adrenal cortex: cortisol and aldosterone.

ADENOID HYPERPLASIA
Adenoid hyperplasia is the over enlargement of the lymph glands located above the back of the mouth.
