Does enriched acoustic environment in humans abolish chronic tinnitus clinically and electrophysiologically? A double blind placebo controlled study.

Animal research has shown that loss of normal acoustic stimulation can increase spontaneous firing in the central auditory system and induce cortical map plasticity. Enriched acoustic environment after noise trauma prevents map plasticity and abolishes neural signs of tinnitus. In humans, the tinnitus spectrum overlaps with the area of hearing loss.

Cosmetic and reconstructive medical tattooing.

Purpose Of Review: Cosmetic and reconstructive medical tattooing techniques are being used with a higher frequency than ever before. The volume of scientific research into its basics, however, is too small to prevent the present occurrence of complications. This review shows that most of the recent articles on the subject are in fact case reports and that many of the complications described result from the failure to conduct more research.

Dermatography as an adjunctive treatment of uni- and bilateral scars in combination with pseudo-hair formation after craniosurgery.

This article describes the use of dermatography as a method to reduce large cosmetically unacceptable scars in the temporo-occipital region after craniosurgery. Over a period of 15 years, 17 patients were treated in two to five 1-hour sessions without local anesthesia. The results show that dermatography is effective in providing a lasting cosmetically satisfactory effect, with subtle pseudo-hair formation and color pigments stably deposited.
