We present a 54-year-old woman who suffered eczematous eruptions on her face after the administration of lidocaine and mepivacaine for dental surgeries. Patch tests showed delayed-type-hypersensitivity to the amide local anesthetics lidocaine and mepivacaine with cross reaction to other amynoacylderivatives (prilocaine,bupivacaine) but not articaine.
Some respiratory symptoms in mushroom growers such as mushroom worker's lung develop by inhalation of certain agents arising from the environment of mushroom cultivation. Recently we observed mushroom workers who had respiratory symptoms which might be type III hypersensitivity reaction to the antigen of Pleurotus floridae. We gave questionnaires to all the mushroom growers at one of the bigges...
Granulomatous inflammation plays a major role in the pathogenesis of a wide variety of diseases caused by infectious agents, including mycobacteria (tuberculosis, leprosy); fungi (coccidioidomycosis, histoplasmosis); worms (schistosomiasis, fllariasis) ; and possibly viruses and protozoa (1, 2). Although it has long been suspected that the granuloma may be a manifestation of delayed hypersensit...
Aim: To assess the awareness of dentinal hypersensitivity among patients visiting dental outpatient department at KMDC hospital, Karachi. Methodology: The data for this cross-sectional study was collected from 361 OPD Karachi Medical and Dental College, After informed consent, a close ended type questionnaire filled were examined dentin hypersensitivity. obtained analysed using SPSS version 22....
BACKGROUND Despite their frequent use, systemic corticosteroids have rarely elicited immediate-type reactions. OBJECTIVE We report two male patients, aged 26 and 70 years, respectively, with severe immediate-type hypersensitivity secondary to the administration of corticosteroids esterified with succinate. METHODS Skin tests, basophil activation tests and challenge tests were performed for ...
Background: Infection is the major cause of death in thermal injury patients. Severe suppression of the immune system is the major cause of infection following burn injury. The aim of this study was to modulate the cell-mediated immune response by the use of cimetidine and pyrimethamine in an animal burn model. Materials and Methods: Male Balb/c mice were anesthetized, and given a 10% total ...
Background and purpose: Atopic dermatitis (AD) is a chronic or relapsing inflammatory skin disease which affects 10–20% of children and 1-3% of adults. Recently microbial agents particularly fungi have received more attention as the aggravating factors of AD. Fungi could be found throughout the world. Some fungal genera are as the normal flora, and some of them are abundantly found in the envi...
Delayed-type hypersensitivity (DTH) 1 is a T cell-mediated reaction resulting in a mononuclear cell-rich inf lammat ion and swelling that peak 24-48 h after local antigenic challenge. In spite of the extensive use of D T H to dissect regulatory (1), genetic (2), and molecular (3) aspects of in vivo T cell responses, little is known of factors that regulate the persistence o f these reactions. I...
