It comprises of tests such as spirometry, gas diffusion test, body plethysmography, bronchial provocation test
, and others.
First used as a topical antimicrobial agent, CHL is now available in different forms and is present in various settings. CHL has the potential to cause Type I and Type IV hypersensitivity reactions, varying from mild cutaneous reactions to anaphylaxis. An increased recognition of CHL-induced hypersensitivity parallels the increased use of CHL in medical care and the increased awareness of allergy. CHL is an important but easily overlooked allergen, and a provocation test
(which serves as the gold standard) is usually difficult to perform.
On the pressure provocation test
, the examiner placed his second and third fingers on the ulnar nerve immediately proximal to the cubital tunnel, and exerted pressure for 30 to 60 seconds, with the subject's elbow flexed to about 20[degrees] and the forearm supinated (1,9,10).
For example, in one report, a reported sensitivity of 93% and specificity of 78% were found, only when three or more of six diagnostic tests (distraction provocation test
, Gaenslen's test, thigh thrust provocation test
, sacral thrust test and compression provocation test
) were positive, while other studies have not supported these findings6,7.
Compared to the placebo group, the LPP group had reduced reactivity to a conjunctival provocation test
(P < 0.001) and, during the pollen season, a lower rhinoconjunctivitis quality of life global score (P = 0.005).
We report here the case of a 51-year old female psoriatic patient with angioedema (without urticaria) due to oral acitretin, confirmed by a positive oral provocation test
. To the best of our knowledge, this is the second description of such an adverse reaction to acitretin.
Abbreviations IgE -- immunoglobulin E sIgE -- specific immunoglobulin E DPT -- drug provocation test
ST -- skin test SPT -- skin prick test IDT -- intradermal test tIgE -- total IgE DST -- delayed skin test PPL -- benzylpenicilloyl poly-L-lysine MDM -- minor determinant mix Determination of specific immunoglobulin E (sIgE) is a part of the diagnostic protocol in suspected penicillin allergy.
The median values before and after the provocation test
Parameters Basal Peak p (medianlQR) (median-IQR) LH (mlU/mL) 2.90-3.40 34.80-19.90 0.018 FSH (mlU/mL) 2.20-0.60 4.20-1.40 0.018 TSH ([micro]lU/mL) 1.64-3.43 2.35-4.02 0.028 LH: Luteinizing hormone, FSH: Follicule stimulating hormone, TSH: Thyroid stimulating hormone, IQR: Interquartile range
Pain provocation test
using IR at 90[degrees] of hip flexion had excellent specificity (96%, 95% confidence intervals [CIs], 0.77% - 0.998%) but poor sensitivity (50%, 95% CI, 0.26% - 0.74%) for identifying labral tear in participants reporting hip pain.
In this report, we present an unusual case of TCM induced by coronary angiography (CAG) with an ergonovine provocation test
that was complicated with cardiac tamponade.
