Background Cytotoxic mechanisms are involved in most forms of drug-induced skin diseases, but till now only a small number of studies has been addressed the question whether in vitro detection of cytotoxic drug-specific response could be helpful in drug hypersensitivity diagnosis. The aim of this study was to assess and compare different cytotoxic tests as an alternative nonradioactive approach...

The literature on lead toxicology has been critically reviewed to provide a safety assessment of lead acetate as a hair colouring. The main objectives were: (i) to determine the additional lead contribution from hair-colouring use to the total daily environmental lead intake; and (ii) to assess the toxicological significance of this additional contribution. The review also focuses attention on ...

Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a rare and potentially fatal adverse drug reaction associated with skin rash, fever, eosinophilia, and multiple organ injury. A number of pharmacological agents are known to cause DRESS syndrome such as allopurinol, anticonvulsants, vancomycin, trimethoprime-sulfamethoxazole, and pyrimethamine-sulfadiazine. Here, we descr...

Neonatal skin suffers a progressive adaptation to the extrauterine environment and special care is needed during this period. This skin is very sensitive, thin and fragile. Immaturity of the epidermal barrier reduces the defense against the excessive proliferation of microbes and makes the skin more vulnerable to trauma and percutaneous drug toxicity. Because of the peculiar characteristics of ...

Introduction: Different types of allergic conditions develop in the half of patients infected with HIV due to the immune system dysfunction. Increased prevalence of allergic conditions in HIV infected patients lead us to conduct the study of allegro reactivity by carrying out skin tests to different types of allergens including an allergen to Candida. Objective: To study the immediate type skin...

Correspondence To the Editor: A 65‑year‑old woman was admitted to Peking Union Medical College Hospital because of rash with pruritus for 1 month after taking Euthyrox. Rash attacked without other symptoms 20 days after she took Euthyrox 50 μg once a day and aggravated when Euthyrox was continued for the next 2 days. The past history included partial thyroidectomy for hyperthyroidism in 1982; t...

Psoriasis is a common, chronic and relapsing inflammatory skin disease. It affects approximately 2% of the western population and has no cure. Combination therapy for psoriasis often proves more efficacious and better tolerated than monotherapy with a single drug. Combination therapy could be administered in the form of a co-drug, where two or more therapeutic compounds active against the same ...

Drug reaction with eosinophilia and systemic symptom (DRESS) syndrome is a type of severe adverse drug-induced reaction. Dermatologists should make a quick diagnosis and provide appropriate treatment for DRESS syndrome to reduce mortality rates, which can be as high as 10%. We present the case of a 47-year-old man with schizoaffective disorder treated with lamotrigine who developed DRESS syndro...

Background Drug reaction with eosinophilia and systemic symptoms (DRESS) is a severe drug-induced reaction that involves both the skin and the viscera. Several herpesvirus family members like EBV or HHV-6 can be detected coincidently with various clinical symptoms in DRESS. In addition, we have previously identified activated EBV specific cytotoxic CD8+ T cells as major actors in the pathophysi...
