Tattoo is a permanent body modification relevant to women’s bodily experiences. Previous studies on the population of tattooers have focused mainly on searching for negative or positive aspects of ...tattooing, mainly in the field of self-esteem. The aim of this study was to explore the mental body representations of tattooed women during emerging adulthood. Three hundred and twenty-seven women with tattoos, aged 18 to 25 (
M
= 21.48;
SD
= 2.05), participated in the study. In the study, we adopted a quantitative research project; the data for analysis was obtained from questionnaires that were completed online between January and March 2021. Women with tattoos completed a survey containing demographic questions, questions regarding their tattoos, the Battery of Tests of Body Self Representations, and the Rosenberg Self-Esteem Scale. Based on that a cluster analysis, we have discovered three types of mental body representations that may characterize them: (1) unstable, (2) disordered, and (3) integrated. The study showed that having a tattoo is associated with experiencing carnality in a specific way.
Tattoos have fascinated mankind for centuries. Although these body marks were once considered to be permanent, technical and scientific progress in recent years has made it possible to remove tattoos ...by various treatment modalities. Contemporary technology involves the use of nonablative quality-switched lasers, which are considered to be the gold-standard treatment option for the removal of unwanted tattoo ink. Current research in the field of tattoo removal is focused on faster lasers and more effective targeting of tattoo pigment particles including picosecond laser devices, multi-pass treatments, dermal scatter reduction, application of imiquimod, and the use of microencapsulated tattoo ink.
To describe a long-term outcome of a new technique using the femtosecond laser to assist with keratopigmentation (corneal tattooing).
Nineteen eyes of 18 patients with a history of significant visual ...disability related to iris defects underwent femtosecond laser-assisted keratopigmentation (FAK) for functional restoration of their visual disabilities. Postoperative visual acuity and symptomatic resolution were collected during their postoperative visits.
After FAK surgery, all patients had improvement in their previous visual-related symptoms. Eighteen of 19 eyes (94%) had improvement in their best-corrected Snellen visual acuity. Eight of 19 eyes (42%) had at least 1 line improvement, 8 of 19 eyes (42%) had at least 2 lines of improvement, and 2 of 19 eyes (10%) had at least 3 lines improvement. The average follow-up period was approximately 60 months.
The FAK technique offers a long-term effective and safe technique for visual disabilities and improves visual acuity in patients with various traumatic iris defects.
Oligometastatic disease has expanded the indications for nonspine bone stereotactic body radiation therapy (NSB SBRT). We investigated whether optical surface monitoring systems (OSMS) could enable ...tattoo-less setup and substitute for 2-dimensional/3-dimensional or cone beam computed tomography (CBCT)-based mid-imaging in NSB SBRT.
OSMS was incorporated in parallel with an existing workflow using pretreatment CBCT and 2-dimensional/3-dimensional kV/kV mid-imaging beginning November 2019. The ability of OSMS to detect out-of-tolerance (>2 mm/>2°) and commanded couch shifts was analyzed. A workflow incorporating OSMS reference captures, CBCT for pretreatment verification, and OSMS/triggered imaging (TI) for intrafraction monitoring was developed for rib/sternum SBRT beginning November 2021 and all NSB SBRT beginning February 2022. Treatment time and CBCT-related radiation dose between the OSMS and the non-OSMS intrafraction monitoring group was analyzed pre- and post-OSMS/TI workflow adoption. All fractions were analyzed through statistical process control with use of an XmR chart of treatment time per quarter from February 2019 to February 2023. Special cause rules were based on Institute for Healthcare Improvement criteria.
From February 2019 to February 2023, 1993 NSB SBRT fractions were delivered, including 234 rib, 109 sternum, 214 ilium, and 682 multisite. Over 20 commanded shifts, OSMS could detect 2-mm shifts to within 0.4 mm 67% of the time and 0.8 mm 95% of the time. All NSB SBRT sites showed significant reductions in treatment time, including the greatest improvement in rib total treatment (21.6-13.4 minutes; P = 1.16 × 10
) and beam time (7.9-3.2 minutes; P = 7.32 × 10
). Significant reductions in CBCT-related radiation were also observed for several NSB sites. These process improvements were associated with OSMS adoption.
Adoption of a novel NSB SBRT workflow incorporating OSMS/TI for bone intrafraction motion monitoring reduced treatment time and CBCT-related radiation exposure while also allowing for more continuous intrafraction motion monitoring for NSB SBRT. OSMS/TI enabled the transition to a tattoo-less workflow.
This essay describes the potential for using ethnographic evidence and mummified tattooed skin to reflect on past therapeutic tattoo practice in the Arctic. It also considers the ways in which ...circumpolar concepts of disease emerged in relation to the agency of nonhuman entities. I argue that specific forms of curative tattooing offer interpretive models for the paleopathological and bioarchaeological study of care through an ontological framework of analysis.

Journal Article
Introduction
Preoperative colonoscopic localization for resection of colonic neoplasia, with or without tattooing for guidance, has been extensively used with variable accuracy. Difficulty in ...intraoperative identification of the lesion may lead to resection of an incorrect segment or to a more extensive resection than originally planned. The aim of this study was to evaluate the accuracy of preoperative colonoscopy in determining the site of the lesion.
Methods
A prospectively collected IRB-approved institutional database was retrospectively queried for all consecutive patients who underwent an elective colon resection for neoplasia between 2013 and 2016. Excluded were patients without preoperative colonoscopy reports available for comparison or who underwent emergency surgery. Surgical plan based on preoperative colonoscopic localization with or without tattooing was compared to the final surgery and pathology reports.
Results
203 patients were included mean age 68 (35–92) years; 102 males (50.2%). Preoperative colonoscopy was inaccurate in 16.7% (34 patients) leading to a change in the surgical plan. Patients with transverse or distal lesions were more likely to have a change in final surgical management compared to proximal sided lesions (29.7% vs. 3.9%, respectively;
p
< 0.001). Only 3.8% of the tattooed lesions could not be identified during surgery. Additional intraoperative colonoscopy was needed in 11 patients (5.5%) to verify exact lesion location. Average length of the resected segment was longer in patients who required a change in surgical plan (26.44 cm vs. 22.47 cm;
p
= 0.02).
Conclusion
Inaccurate preoperative colonoscopic localization led to a change in surgical management in 16.7% of cases, especially in transverse or left sided lesions. Surgeons should consider these findings when planning colonic resections.
Purpose
Tattoo fiducials are commonly used in radiotherapy patient alignment, and recent studies have examined the use of UV‐excited luminescent tattoo ink as a cosmetic substitute to make these ...visible under UV illumination. The goal of this study was to show how luminescent tattoo inks could be excited with MV radiation and imaged during beam delivery for direct visualization of field position.
Methods
A survey of nine UV‐sensitive tattoo inks with various emission spectra were investigated using both UV and MV excitation. Images of liquid solutions were collected under MV excitation using an intensified‐CMOS imager. Solid skin‐simulating phantoms were imaged with both surface‐painted ink and in situ tattooing during dose delivery by both a clinical linear accelerator and cobalt‐60 source.
Results
The UV inks have peak fluorescence emission ranging from approximately 440 to 600 nm with lifetimes near 11–16 μs. The luminescence intensity is approximately 6x higher during the x‐ray pulse than after the pulse, however, the signal‐to‐noise is only approximately twice as large. Spatial resolution for imaging was achieved at 1.6 mm accuracy in a skin test phantom. Optical filtering allows for continuous imaging using a cobalt source and provides a mechanism to discriminate ink colors using a monochromatic image sensor.
Conclusions
This study demonstrates how low‐cost inks can be used as fiducial markers and imaged both using time‐gated and continuous modes during MV dose delivery. Phantom studies demonstrate the potential application of real‐time field verification. Further studies are required to understand if this technique could be used as a tool for radiation dosimetry.
