Tolerance induction and desensitization in Stevens-Johnson syndrome (SJS) or in toxic epidermal necrolysis (TEN) have been described as an absolute contraindication by some authors, but there are cases where there is no treatment alternative. Tuberculosis (TB) remains a leading cause of morbidity and mortality in developing countries and ranks alongside HIV as a leading cause of death worldwide. Severe drug reactions, such as SJS and TEN, occurring in these individuals are lifethreatening. Since alternative therapies for TB are limited, the role of desensitization and reintroduction becomes essential...

Alexander Yao, Janet A Wilson, Stephen L Ball
Background: The autonomic nervous system (ANS) richly innervates the nose and paranasal sinuses, and has a significant role in lower airway diseases, e.g., asthma. Nonetheless, its contribution to sinonasal symptoms is poorly understood. This review aimed to explore the complex relationship between the ANS and sinonasal symptoms, with reference to systemic diseases and triggers of ANS dysfunction. Methods: A review of articles published in English was conducted by searching medical literature databases with the key words "autonomic nervous system" and ("sinusitis" or "nose" or "otolaryngology")...

Background: Wogonin is commonly used for the treatment of allergic diseases. However, neither its precise effect in preventing allergic rhinitis (AR) nor its mechanism of action are known. Objectives: In this study, the effect of wogonin on allergic responses in ovalbumin (OVA) induced AR was investigated in mice. Methods: BALB/c mice were sensitized with intraperitoneal (i.p.) OVA and then challenged intranasally with OVA. Wogonin (10 and 30 mg/kg) was given to the treatment groups, and the effect of wogonin on the release of allergic inflammatory mediators, specifically OVA-specific immunoglobulin E (IgE) and inflammatory cytokines, was explored...

Nancy I Joseph, Eileen Slavin, Brian P Peppers, Robert W Hostoffer
Fenugreek ( Trigonella foenum-graecum) is a food product that belongs to the Leguminosae family along with other legumes. It has been used in India, Greece, and Egypt for culinary and medical purposes since ancient times, and today, fenugreek is used for flavoring foods, dyes, and drugs throughout the world. Many members of the Leguminosae family have been associated with allergies including soybean, green pea, and peanut. Fenugreek is also included in this family and may result in allergic reactions. Two cases of anaphylaxis have been described in children after ingestion of curry and pastes that contain fenugreek, although the true nature of the causative agent was unclear...
