hives

Examples of hives in the following topics:

• Comparing Two Independent Population Proportions

  • Two types of medication for hives are being tested to determine if there is a difference in the proportions of adult patient reactions.
  • Twenty out of a random sample of 200 adults given medication A still had hives 30 minutes after taking the medication.
  • Twelve out of another random sample of 200 adults given medication B still had hives 30 minutes after taking the medication.

• Signs and Symptoms of Shock

  • With anaphylaxis, hives may present on the skin, as well as localised edema, especially around the face, weak, and rapid pulse.
  • Hives and flushing on the back of a person with anaphylaxis
  • Hives and flushing on the back of a person with anaphylaxis

• Type I (Anaphylactic) Reactions

  • Symptoms typically include raised bumps on the skin (; hives), itchiness, red face or skin (flushing), or swollen lips.

• Allergies

  • Mild allergies like hay fever are very common in the human population and cause symptoms such as red eyes, itchiness, and runny nose, eczema, hives.
  • A response can take the the form of a rash (urticaria, also known as hives), or, worse—anaphylaxis (a serious reaction that can result in death).

• Allergic Responses to Drugs

  • Other less severe symptoms of an allergic reaction can include, hives, angioedema (tissue swelling under the skin, often on the face), tight throat, coughing, wheezing, or watery eyes.
  • Signs include CNS symptoms such as confusion or lightheadedness, respiratory symptoms such as shortness of breath, gastrointestinal issues such as pain or vomiting, skin issues such as hives or itchiness, vascular symptoms such as change in heart rate or low blood pressure, and swelling of the mouth or eyes.

• Comparing Two Independent Population Proportions

  • Two types of medication for hives are being tested to determine if there is a difference in the proportions of adult patient reactions. 20 out of a random sample of 200 adults given medication $A$ still had hives 30 minutes after taking the medication. 12 out of another random sample of 200 adults given medication $B$ still had hives 30 minutes after taking the medication.

• Viral Skin Diseases

  • At first the rash appears similar to the first appearance of hives.
  • However, unlike hives, herpes zoster causes skin changes limited to a dermatome, normally resulting in a stripe or belt-like pattern that is limited to one side of the body and does not cross the midline.

• Heat Conservation and Dissipation

  • Other ectotherms use group activity, such as the activity of bees to warm a hive to survive winter.

• Diagnosis and Treatment of Allergy

  • This response will range from a slight reddening of the skin to a full-blown hive (called "wheal and flare") similar to a mosquito bite in more sensitive patients.

• Hypersensitivities

  • The effects of an allergic reaction range from mild symptoms such as sneezing and itchy, watery eyes, to more severe or even life-threatening reactions involving intensely-itchy welts known as hives, airway contraction with severe respiratory distress, and plummeting blood pressure.
