The DRESS syndrome is a Type IV, Subtype IVb, hypersensitivity drug reaction, i.e. a reaction dependent on CD4(+) cells and the cell- and tissue-injuring action of eosinophils. [2] [8] Skin lesions inflict 73% to 100% of afflicted individuals; they are generally infiltrative macules and plaques. About 75% of cases exhibit facial edema.
AGEP is an acute drug eruption characterized by numerous small, primarily non-follicular, sterile skin pustules arising within large areas of red swollen skin usually within days of taking an inciting drug. [6] The skin eruptions are often pruritic and accompanied by fever, headache, a high number of neutrophils and eosinophils in the blood ...
Sclereids in a diffuse pattern are dispersed throughout the leaf tissue, and sclereids in a terminal pattern are concentrated about the tips of leaf veins. Sclereid formations in leaves include the branched sclereids of Trochodendron , the columnar sclereids of Hakea , and the hair-like trichosclereids that branch into air chambers within the ...
Diagnosis is based on a skin biopsy and involvement of more than 30% of the skin. [3] TEN is a type of severe cutaneous adverse reactions (SCARs), together with SJS, a SJS/TEN, and drug reaction with eosinophilia and systemic symptoms. [5] It is called SJS when less than 10% of the skin is involved and an intermediate form with 10 to 30% ...
Stevens–Johnson syndrome (SJS) is a type of severe skin reaction. [1] Together with toxic epidermal necrolysis (TEN) and Stevens–Johnson/toxic epidermal necrolysis (SJS/TEN) overlap, they are considered febrile mucocutaneous drug reactions and probably part of the same spectrum of disease, with SJS being less severe.
Amid mounting fears over the potentially deadly diseases the creatures can spread, one mother is raising concerns about a type of tick so small most people wouldn't be able to spot it on their own ...
Immediately rinse skin with rubbing alcohol, poison plant wash, or degreasing soap (such as dishwashing soap) or detergent, and lots of water. Rinse frequently so that wash solutions do not dry on ...
Livedo reticularis is a common skin finding consisting of a mottled reticulated vascular pattern that appears as a lace-like purplish discoloration of the skin. [1] The discoloration is caused by reduction in blood flow through the arterioles that supply the cutaneous capillaries, resulting in deoxygenated blood showing as blue discoloration ().
