“…Exceptional cases have been described in old tattoos with rather long delay of onset (9 and 10 years). In 2 other cases, the tattoos were very old tattoos (21 and >50 years), but the articles failed to provide delay of onset [4]. Multiple (>1) lesions are observed in 40.5% of the cases.…”

“…Our review confirms a specific pattern of KA affecting mostly red tattoos on the extremities of middle-aged individuals. Apart from getting a new tattoo, other triggering factors include an old tattoo touched-up, laser removal, or sun exposure after tattooing [4]. KA can be associated with immunosuppression, ultra-violet (UV) or X-rays, drug treatments, foreign bodies, and various trauma (surgery, peels, abrasions, cryotherapy, and photodynamic therapy) [16].…”

“…We excluded cases of pseudo-epitheliomatous hyperplasia. The first author has already published an exhaustive review of 31 patients in 2017 in French [4]. The present review is an update with the addition of the most recent cases [5-13] as well as two cases diagnosed at the “Tattoo consultation” in Bichat – Claude Bernard Hospital, in Paris [14, 15].…”

“…A malignant or premalignant lesion can also be inadvertently tattooed over, and its evolution masked by the drawing. On the other hand, reports of rapidly arising, isolated or multiple KAs and SCCs on the red part of tattoos tend to suggest a non-fortuitous link with the procedure [4]. We herein review all case reports of KAs and SCCs that occurred on tattoos thus far and analyze the clinical features of the patients with such complications.…”

Future Prospects for Clinical Applications of Nanocarbons Focusing on Carbon Nanotubes

et al. 2022

View full text Add to dashboard Cite

Over the past 15 years, numerous studies have been conducted on the use of nanocarbons as biomaterials towards such applications as drug delivery systems, cancer therapy, and regenerative medicine. However, the clinical use of nanocarbons remains elusive, primarily due to short‐ and long‐term safety concerns. It is essential that the biosafety of each therapeutic modality be demonstrated in logical and well‐conducted experiments. Accordingly, the fundamental techniques for assessing nanocarbon biomaterial safety have become more advanced. Optimal controls are being established, nanocarbon dispersal techniques are being refined, the array of biokinetic evaluation methods has increased, and carcinogenicity examinations under strict conditions have been developed. The medical implementation of nanocarbons as a biomaterial is in sight. With a particular focus on carbon nanotubes, these perspectives aim to summarize the contributions to date on nanocarbon applications and biosafety, introduce the recent achievements in evaluation techniques, and clarify the future prospects and systematic introduction of carbon nanomaterials for clinical use through practical yet sophisticated assessment methods.

Background: Little is known about sun-exposure and sun-protection behaviors among tattooed individuals.Objectives: This study sought to investigate the sun-exposure and sunprotective habits among tattooed individuals. Methods: Population-based study using a representative sample of the general population aged ≥18 years from four countries (Brazil, China, Russia and United-States). All participants were asked to fill in a digital structured questionnaire. We inquired about socio-demographics, self-evaluation of their skin phototype (from I to VI), tattoo(s) and sun-exposure and sun-protection habits.Results: A total of 9031 adult participants responded to the questionnaire of whom 1682 (18.6%) had ≥ 1 tattoo(s). The prevalence of tattoos was significantly higher among individuals with lighter skin tone (phototype I to III, 20.2%) compared to those with darker one (phototype IV to VI, 13.9%, p<0.001). Almost 20% percent of the tattooed individuals acknowledged heavy lifestyle sun-exposure compared to 11% of those without tattoos (p<0.001). Multinomial analyses showed that Brazilians and those having ≥ 1 tattoo were more likely to have intermediate and intense lifestyle sun-exposure. Tattooed individuals were more likely to report that they used regular or occasional sunprotection methods than non-tattooed individuals (p < 0.001 and 0.016 respectively). Multinomial analyses for regular sun-protection methods showed significant association with respondents from Brazil and those having one tattoo, but not more than one tattoo. Limitations include mainly that this is a questionnaire-based study and and we lack of questions about sunburns and skin cancers. Conclusions: This large population-based study shows that tattooed individuals do have a heavily sun-exposed lifestyle but, at the same time, display sun-protection habits.
