Milk allergy is an adverse immune reaction to one or more proteins in cow's milk.Symptoms may take hours to days to manifest, with symptoms including atopic dermatitis, inflammation of the esophagus, enteropathy involving the small intestine and proctocolitis involving the rectum and colon. [2]
The severity of these signs and symptoms typically increases with the amount of lactose consumed; most lactose-intolerant people can tolerate a certain level of lactose in their diets without ill effects. [16] [17] Because lactose intolerance is not an allergy, it does not produce allergy symptoms (such as itching, hives, or anaphylaxis).
A drug allergy is an allergy to a drug, most commonly a medication, and is a form of adverse drug reaction. Medical attention should be sought immediately if an allergic reaction is suspected. An allergic reaction will not occur on the first exposure to a substance.
This can cause elevated physical temperature, painful spasms of the intestinal muscles , swelling due to fluid leaking from capillaries of the intestine and further tissue damage by the body's immune cells and the chemicals, called cytokines, which are released to fight the infection. The result can be impaired nutrient absorption, excessive ...
Identifying an allergy to penicillin requires a hypersensitivity skin test, which diagnoses IgE-mediated immune responses caused by penicillin. This test is typically performed by an allergist who uses a skin-prick and intradermal injection of penicilloyl-polylysine, a negative control (normal saline), and a positive control ( histamine ).
This mechanism causes allergies to typically give immediate reaction (a few minutes to a few hours) to foods. Food intolerances can be classified according to their mechanism. Intolerance can result from the absence of specific chemicals or enzymes needed to digest a food substance, as in hereditary fructose intolerance.
In clinical medicine, antibiotics are most frequently prescribed on the basis of a person's symptoms and medical guidelines. This method of antibiotic selection is called empiric therapy, [1] and it is based on knowledge about what bacteria cause an infection, and to what antibiotics bacteria may be sensitive or resistant. [1]
It usually manifests in 1–3 hours after the first dose of antibiotics as fever, chills, rigor, hypotension, headache, tachycardia, hyperventilation, vasodilation with flushing, myalgia (muscle pain), exacerbation of skin lesions and anxiety. The intensity of the reaction indicates the severity of inflammation.
