Objective: This study aimed to estimate the prevalence of lichenoid reactions to Anti Hyperglycemic Agents. Materials and Methods: In this cross-sectional descriptive and analytic study, we examined the oral mucosa of 411 patients at the age of 29 to 85 in 3 groups who consumed various antihyperglycemic agents. Results: In overall, 31 patients had lichenoid reactions (12 patients taking glibe...

Background: Adverse cutaneous drug reactions are unwarranted effects of modern medicine. These unfortunate events can assume any morphology from simple exanthem to full blown toxic epidermal necrolysis (TEN), and can simulate and mimic many diseases. Sometimes it is difficult to recognize the cause, but they may be due to polypharmacy or self-administration of medications. The analytical data f...

A salt metathesis reaction is a chemical process involving the exchange of bonds between two reacting chemical species, which results in the creation of products with similar or identical bonding affiliations. Hyperstructure theory is studied from the theoretical point of view and for its applications. In this paper, we provide some examples of hyperstructures associated with salt m...
