latory, and gastrointestinal systems. Although allergic
IgE-mediated reactions to drugs are generally thought
to be frequent causes of drug-induced urticaria, systemic anaphylaxis or urticaria can also be caused by
drugs or biological agents that are responsible for direct mediator release from mast cells or basophils. Urticaria heals without skin lesions.

Urinary ract Infection
Invasion by living pathogenic microorganisms of the
urine-producing tract, where conditions are favorable
to their growth and from where their toxins may gain
access to, and act injuriously upon, the tissues.

Urticaria
Urticaria is characterized by pruritic, erythematous
wheals, usually resolving within 24 hours. Urticaria
may develop as part of cutaneous manifestations of
systemic anaphylaxis including the pulmonary, circu-
UVA Radiation
320–400 nm range. Also known as "long-wave ultraviolet" or "near UV" (because it is adjacent to visible),
or "black light." Subdivided into UVA II (320–
340 nm) and UVA I (340–400 nm). In Europe, frequently defined as 315–400 nm, based on CIE denotation.
Photoreactive Compounds
UVC Radiation
200–290 nm range. Also called "germicidal radiation"
or "shortwave UV". Not found in sunlight at the surface of the earth because it is filtered by ozone and
water vapor.
