Dimetindene maleate (DMM, Fenistil, CAS 3614-69-5) a specific H1-receptor antagonist, is therapeutically used for the treatment of respiratory allergies, urticaria, itching dermatoses and generally pruritic sensations occurring with various diseases. As it exhibits local anaesthetic activity in the rabbit cornea and the local anaesthetic activity of a couple of H1-antagonists was found to be linearly correlated to the H1-potency represented by the pA2-values--and dimethindene maleate demonstrates a high pA2-value--it seemed worth investigating the local anaesthetic potency in man making use of an objective and well validated pain model, the Laser algesimetry. The study was carried out with 24 healthy volunteers in a double-blind placebo- and reference-controlled, randomized, cross-over design. Three different medications were applied with occlusive dressing: DMM, lidocaine, and placebo. Selective thermo-noxious stimulation of A-delta- and C-fibers was induced by a CO2-laser. Somato-sensory evoked vertex potentials (SEPs) were simultaneously recorded. Both verum treatments showed a remarkable analgesic potency compared to placebo. Effects were preferably concentrated on the peripheral N1-component of the SEPs. The overall means of the N1-amplitudes were suppressed compared to placebo by both active drugs, with the effects being more pronounced for DMM.

The significant resurgence of bedbugs in the past decade has been attributed to pesticide resistance, more frequent travel, lack of public awareness, and inadequate pest control programs. Bedbugs are obligate blood parasites (insect family Cimicidae). They can withstand a large range of temperatures but are attracted to warmth and carbon dioxide. They typically feed just before dawn. Cutaneous reactions to bedbug bites can include macules, papules, wheals, vesicles, bullae, and nodules. Bites may be confused with other skin conditions. Bedbug bite reactions are typically self-limited and resolve within one to two weeks without treatment. Bedbug infestation may cause significant psychological distress. The diagnosis of a bedbug infestation is based on history, appearance of bites, and inspection of sleeping quarters. Although there is no evidence that bedbugs transmit disease, systemic reactions may include asthma, angioedema, generalized urticaria, iron deficiency anemia, and, rarely, anaphylaxis. An integrated pest management strategy should be employed to eliminate infestation. Tactics include vacuuming, heat or cold treatment, trapping devices, and pesticides.
