BACKGROUND Tattoos of natural red/brown henna obtained from the indigenous tree Lawsonnia have been traditionally performed with a few side-effects. Nowadays black henna tattoos are usually performed even in children. The addition of several chemical agents to improve its cosmetic properties has increased the risk of developing contact dermatitis after exposure. Our aim is to determine the caus...

The skin is an attractive organ for immunization because of the presence of antigen-presenting cells. Intradermal delivery via tattooing has demonstrated superior vaccine immunogenicity of DNA vaccines in comparison to conventional delivery methods. In this study, we explored the efficacy of tattoo injection of a tumor vaccine based on recombinant Semliki Forest virus replicon particles (rSFV) ...

OBJECTIVE The purpose of this UK study was to evaluate interfraction reproducibility and body image score when using ultraviolet (UV) tattoos (not visible in ambient lighting) for external references during breast/chest wall radiotherapy and compare with conventional dark ink. METHODS In this non-blinded, single-centre, parallel group, randomized control trial, patients were allocated to rece...

SUMMARY Skin cancer formation is on the rise. Only a few case reports, which focus on skin cancer being caused by tattoos, have been published so far. Our aim is to determine whether skin cancer occurrence can be triggered by tattoos. In our presented case, a squamous-cell carcinoma developed inside of the red areas of a multicolored tattoo within months. Furthermore, surgical removal of the ca...

BACKGROUND Cryotherapy combined with intralesional triamcinolon injection is the most common traditional therapy for hypertrophic scars and keloids. The literature contains few articles on the use of bleomycin tattoo for treatment of these conditions. OBJECTIVE This study compares the efficacy of bleomycin tattoo with that of cryotherapy combined with intralesional triamcinolon injection for ...

BACKGROUND This study examines the underlying characteristics of adolescents attending Italian secondary school who expressed indifference towards or no interest at all in body art. METHODS A convenience sample of 4,277 secondary school students from the North Eastern Italy were surveyed with a self-reported questionnaire collecting extensive socio-demographic information.

The demand for encoded surfaces has increased significantly over the past decade driven by rapid digitalization of world. Surface-enhanced Raman scattering (SERS) offers unique capabilities in generation surfaces. challenge is limited versatility SERS-based encoding systems terms applicable This study addresses this using a temporary tattoo approach together with simplified fabrication SERS-act...

INTRODUCTION This quality improvement study tested three methods of tattoo alignment and isocentre definition to investigate if aligning lateral tattoos to minimise pitch, roll and yaw decreased set-up error, and if defining the isocentre using the lateral tattoos for cranio-caudal (CC) position improved isocentre reproducibility. The study population was patients receiving curative external be...

Since laser treatment of tattoos is the favored method for the removing of no longer wanted permanent skin paintings, analytical, biokinetics and toxicological data on the fragmentation pattern of commonly used pigments are urgently required for health safety reasons. Applying dynamic headspace-gas chromatography with mass spectrometric detection (DHS-GC/MS) and comprehensive two-dimensional ga...

Assessment of a patient with probable allergic contact dermatitis caused by a tattoo ink is a difficult task, because regulations regarding the substances used as tattoo inks continue to be limited, and ink component information is difficult to access (1). Moreover, in most cases, patch testing with the culprit ink is often of little benefit. We report a case in whom patch testing with the ink ...
