Severe allergic reaction to diethyltoluamide (DEET) containing insect repellent
Case presentation A 53 year-old female bridge inspector presented with allergic reaction to diethyltoluamide (DEET) containing insect repellent. She had prior use without difficulty. In 2013, she used the insect repellent and with only a small amount making contact with her forehead, she had immediate pruritus and erythema on her forehead, persisting for an hour. The following week, she used a ...
متن کاملShort Communication INSECT REPELLANT INTERACTIONS: SUNSCREENS ENHANCE DEET (N,N-DIETHYL-M-TOLUAMIDE) ABSORPTION
Toxicology studies are typically performed on single compounds, which we hypothesized would miss adverse synergies from chemical mixtures. This hypothesis was tested using an insect repellant and sunscreens because both groups include known permeation enhancers, with prior pediatric reports of toxicity from highly concentrated DEET (N,N-diethyl-m-toluamide). Using real-time mass spectroscopy in...
متن کاملTheophylline-Ethylcellulose Microparticles: Screening of the Process and Formulation Variables for Preparation of Sustained Release Particles
Objective(s) The aim of this study was to formulate and evaluate microencapsulated controlled release preparations of theophylline using ethylcellulose as the retardant material with high entrapment efficiency. Materials and Methods Microspheres were prepared by water-in-oil-in-oil (W/O1/O2) emulsion-solvent diffusion (ESD). A mixed solvent system consisting of acetonitrile and dichloromet...
متن کاملDiethyltoluamide (DEET) increases CD63 expression in a contact urticaria patient's basophils.
The use of insect repellent has increased during recent years to prevent insect stings and its feared consequences of virus and parasitic diseases transmitted by infected mosquitoes and tick bites. DEET (N, N-diethyl-3-toluamide) is the most effective and most widely-used insect repellent and it is used by approximately 30% of the population. The DEET Registry is a post-marketing surveillance s...
متن کاملPreparation of Ethyl Cellulose Microspheres for Sustained Release of Sodium Bicarbonate
Sustained release of thermal-instable and water-soluble drugs with low molecule weight is a challenge. In this study, sodium bicarbonate was encapsulated in ethyl cellulose microspheres by a novel solid-in-oil-in-oil (S/O/O) emulsification method using acetonitrile/soybean oil as new solvent pairs. Properties of the microspheres such as size, recovery rate, morphology, drug content, and drug re...
