Tattoo artists use many compounds to create tattoo pigment and several allergic reactions can occur as a result of these additives. The compositions of many inks have been identified; however, as new mixtures are created it becomes difficult to identify the specific ingredients in a particular ink. Allergic reactions to a particular pigment can manifest in(More)
One of the major limitations to the study of the development of the nervous system in aneuploid mammalian embryos is that the aneuploid condition is usually lethal in utero. Liveborn aneuploid individuals often succumb rapidly because they have a constellation of malformations incompatible with postnatal survival. We have developed a selective tissue(More)
BACKGROUND Ultraviolet radiation (UVR) contributes to the vast majority of nonmelanoma skin cancer (NMSC). As the incidence of NMSC continues to rise, topical therapies will be used with increasing frequency. Topical therapies may benefit high-risk surgical candidates as an alternative treatment modality and may improve overall cosmesis. The most commonly(More)
Anatomic and functional abnormalities of the colon are known to cause a variety of abdominal complaints, including constipation, diarrhea, and pain. We describe a patient with dolichocolon (elongated colon) with transient spasm (pseudo-obstruction) associated with exertion. The diagnosis in this case rested with a novel approach and less invasive evaluation(More)
While placement of ink into the skin is a long-standing tradition, patients are now seeking tattoo removal on a more frequent basis. Once considered acceptable removal options, tattoo ink removal via physical destruction included dermabrasion, chemical destruction, salabrasion, thermal destruction, and cryotherapy. Now these options are used extremely(More)
It is widely accepted that Q-switched lasers are the gold-standard treatment for the resolution of unwanted tattoo ink. Although much safer than other tattoo removal modalities, the treatment of tattoo ink with Q-switched devices may be associated with long-term adverse effects including undesired pigmentary alterations such as tattoo ink darkening.(More)
BACKGROUND Tattoo removal using Q-switched lasers is well established in the medical literature, but it is not clear how tattoos on mucosal membranes should be treated because of their infrequent presentation. OBJECTIVE To report successful cosmetic tattoo removal using Q-switched laser irradiation on the oral mucosal surface. MATERIALS AND METHODS(More)
BACKGROUND Laser tattoo removal using quality switched technology is widely accepted as the standard of care. Determining the risk of hypertrophic scarring and keloid formation more precisely delineates the safety of this procedure and improves patient education regarding the risk of scarring. OBJECTIVE To investigate the incidence of hypertrophic(More)
