A positive APT was defined by erythema with infiltration or papules, and a positive SPT by a wheal
[greater than or equal to] 3 mm.
SET is a modified method of IDT in which serially diluted antigen extracts are used to determine the minimum amount of antigen that is required to elicit a significant allergic response, quantified by comparing the size of wheal
increase with that evoked by a negative control test.
Severe itching, disfiguring wheals
and disturbed sleep may be associated with impaired daily activities, emotional disturbances and poor quality of life.
None of the children developed a wheal
at the vaccine skin prick site that was at least 3 mm larger than the wheal
from the saline control, so all had negative skin prick test results, said Dr.
The reduction in wheals
5 hours after administration of 5 mg of desloratadine compared with baseline was 50% greater than with spontaneous resolution.
Sequel features by-wire braking, steering and chassis control The steer-by-wire system uses two motors up front and one in the rear to steer the rear wheals
, similar to the Quadrasteer system designed by Delphi for GM's pickup trucks and Mi-size SUVs.
A positive reaction at the negative control site is associated with dermographism, in which trauma to the skin causes wheals
This patient has urticaria (hives), presenting as variously shaped wheals
on his chest and arms, resulting from a drug allergy.
Chronic urticaria is one of the commonest dermatological problems encountered in clinical practice which is characterized by wheals
occurring daily or almost daily for duration of more than 6 weeks.
It varies torque distribution to individual wheels under slippery conditions, and even if three wheals
lose traction, 4MATIC can direct power to any one wheel to keep the car moving.
Chronic idiopathic urticaria is defined as daily or almost daily occurrence of urticarial wheals
for at least 6 weeks.
There was no history suggestive of angioedema or wheals
