Context Specimen misidentification is the most significant error in laboratory medicine, potentially accounting for hundreds of millions of dollars in extra health care expenses and significant morbidity in patient populations in the United States alone. New technology allows the unequivocal documentation of specimen misidentification or contamination; however, the value of this technology currently depends on suspicion of the specimen integrity by a pathologist or other health care worker. Objective To test the hypothesis that there is a detectable incidence of unsuspected tissue specimen misidentification among cases submitted for routine surgical pathology examination...

Advances in three-dimensional (3D) printing have increased feasibility towards the synthesis of living tissues. Known as 3D bioprinting, this technology involves the precise layering of cells, biologic scaffolds, and growth factors with the goal of creating bioidentical tissue for a variety of uses. Early successes have demonstrated distinct advantages over conventional tissue engineering strategies. Not surprisingly, there are current challenges to address before 3D bioprinting becomes clinically relevant...

Regeneration is a concept that has fascinated humans for centuries. Whether we have been trying to bring things back to life, extract additional resources from the world, or remodel our living spaces-domestic and urban-it is often presented as an unproblematic force for good. But what exactly does it mean to regenerate a body, mind or space? This paper, which introduces a collection of contributions on the theme of human regeneration, explores the limits and possibilities of regeneration as a conceptual tool for understanding the biological realm...

Over the past several decades, historians of science have come increasingly to focus on the role of so-called "paper technologies," reorganizing and transforming information through the use of paper and pen, in the emergence of modern science. Taking as a case study an effort by administrators in the seventeenth-century German princely state of Saxe-Gotha to enlist foresters and herb-women to catalog the medicinal plants of the territory, this article analyzes the varied forms of paperwork produced in the process, including an extremely unusual table, and argues that the table represented an effort to produce a synoptic visualization, akin to but not identical to a map, of the location of the territory's herbs...

Therapeutic proteins provide interventions for some of the most complex and intractable diseases and are an essential part of modern medicine. Immunogenicity is the development of immune responses, usually measured by antibodies, to therapeutic proteins. These responses can adversely affect the safety and efficacy of the therapeutic agent and may have the following consequences: neutralization of a life-saving biotherapeutic, crossreactivity to non-redundant endogenous proteins, and hypersensitivity responses...

Mucocutaneous diseases and conditions, including aging, are known to be the result of multiple pathophysiologic anomalies induced by various environmental insults. Creating therapeutic products for these multifactorial diseases and conditions is challenging. Although safety testing is not required for cosmetics and cosmeceuticals, consumer expectation is for products to be effective and well tolerated while maintaining cosmetic elegance. This requires that the finished product being sold to consumers should be tested in human clinical trials for safety profile, efficacy, and scientific integrity...

Artificial intelligence (AI) is emerging as a technology with the power to transform established industries, and with applications from automated manufacturing to advertising and facial recognition to fully autonomous transportation. Advances in each of these domains have led some to call AI the "fourth" industrial revolution [1]. In healthcare, AI is emerging as both a productive and disruptive force across many disciplines. This is perhaps most evident in Diagnostic Radiology and Pathology, specialties largely built around the processing and complex interpretation of medical images, where the role of AI is increasingly seen as both a boon and a threat...
