Since the early 1990s this view changed with the recognition of autochthonous cutaneous leishmaniasis. The first documented case in 1992 was a young man from Ambalantota who initially gave a history of contact with dry zone jungle but later denied this history (1). This was followed a few years later by a number of cases from different parts of the island. The second and third case reports were...
The total blood lymphocyte proliferation assay (TLP) was evaluated as a screening test for infection with Mycobacterium tuberculosis and was compared with the tuberculin (Mantoux) skin test. The results of TLP assays performed on 33 patients with tuberculosis and 37 non-tuberculous subjects were compared with results of skin tests performed in the previous year. There was a high correlation bet...
Sequential skin testing including immediate patch test (IPT), skin prick test (SPT), and intradermal test (IT) with sodium benzylpenicillin G (Pen G), and SPT with benzylpenicilloyl human serum albumin (BPO-HSA) was done in 58 subjects with a history of probable anaphylactic reaction or shock of unknown cause. Based on positive skin tests, the diagnosis of penicillin anaphylaxis was confirmed i...
Medications often interfere with allergy skin test interpretation. This study was performed to determine which medications interfere with allergy skin tests. We retrospectively reviewed skin-prick test results from patients who had discontinued H(1)-antagonists, tricyclic antidepressants (TCAs), selective serotonin reuptake inhibitors (SSRIs), selective norepinephrine reuptake inhibitors (SNRIs...
BACKGROUND Hypersensitivity to penicillin has been studied worldwide, but data regarding patterns of sensitization in Arabian Gulf countries are scarce. OBJECTIVE To describe the patterns of penicillin hypersensitivity during a 6-year study in Kuwait in terms of demographics, type of the culprit drug, in vivo and in vitro allergy testing. METHODS One hundred and twenty-four patients referre...
To the Editor: In their review article, Getahun et al. (May 28 issue)1 provide a useful overview of issues surrounding latent tuberculosis infection. However, newly published data regarding the performance of the T-SPOT.TB assay call into question the supposition that false conversions and reversions are more common with interferon-γ release assays (IGRAs) than with tuberculin skin tests.2 Spec...
The European Cosmetics Directive and REACH have accelerated the need for alternative tests. Especially the animal testing ban of cosmetic ingredients from 2009 strongly impacts on the timely delivery of relevant methods. ECVAM's key area "topical toxicity" focuses on skin and eye irritation/corrosion, phototoxicity and percutaneous absorption. Regulatory accepted alternative tests are available...
Skin tests are of paramount importance for the evaluation of drug hypersensitivity reactions. Drug skin tests are often not carried out because of lack of concise information on specific test concentrations. The diagnosis of drug allergy is often based on history alone, which is an unreliable indicator of true hypersensitivity.To promote and standardize reproducible skin testing with safe and n...
Currently, lattice composite structures have many applications in aerospace industries. The present research analyzed the effect of an external skin consisting of a lattice’s cylindrical shell on the buckling strength of composite materials, both numerically and experimentally. Two classes of specimens, with and without external skins, were fabricated using the filament winding process. To find...
The principal surveillance tool used to control bovine tuberculosis in cattle is the removal of animals that provide a positive response to the tuberculin skin-test. In this study we performed a longitudinal investigation of the immunological and diagnostic consequences of repeated short-interval skin-tests in cattle naturally infected with Mycobacterium bovis. Tuberculin skin-test positive cat...
