3D-printed temporal bone models for training: Does material transparency matter?

Purpose: To investigate the impact of 3D-printed temporal bone models with two different material transparencies on trainees' mastoidectomy performance.

Methods: Eleven ORL residents performed two anatomical mastoidectomies with posterior tympanotomy on two 3D-printed models with different transparency and VR simulation training. Participants where divided into two groups based on their experience.

Sleep disorders and criminal behavior.

Behaviors that would otherwise be considered criminal acts, but occur in the context of a sleep disorder, pose challenges to the traditional application of legal principles of criminal responsibility. Determining the degree to which consciousness is present during such behaviors becomes a necessary step in assigning criminal culpability. Historically, legal defense theories of unconsciousness, automatism, and insanity have been raised to negate culpability for parasomnia related behaviors.

3-D-Printed Models for Temporal Bone Training: A Validity Study.

Objective: 3-D printing offers convenient and low-cost mastoidectomy training; nonetheless, training benefits using 3-D-printed temporal bones remain largely unexplored. In this study, we have collected validity evidence for a low-cost, 3-D-printed temporal bone for mastoidectomy training and established a credible pass/fail score for performance on the model.

Study Design: A prospective educational study gathering validity evidence using Messick's validity framework.

3D-printing a cost-effective model for mastoidectomy training.

Background: 3D-printed temporal bone models can potentially provide a cost-effective alternative to cadaver surgery that can be manufactured locally at the training department. The objective of this study was to create a cost-effective 3D-printed model suitable for mastoidectomy training using entry level and commercially available print technologies, enabling individuals, without prior experience on 3D-printing, to manufacture their own models for basic temporal bone training.

Methods: Expert technical professionals and an experienced otosurgeon identified the best material for replicating the temporal bone and created a cost-effective printing routine for the model using entry-level print technologies.

The Case Against "Excited Delirium".

Citizens' deaths in police custody are sometimes attributed to "excited delirium syndrome" (ExDS). This terminology is rejected by the American Medical Association and the American Psychiatric Association. ExDS has no demonstrable pathology but has been proposed as predisposing to sudden death, thus exonerating police.

Involuntary Administration of Long-Acting Injectable Antipsychotics for Competency Restoration.

In implementing the decisions in the landmark case , jurisdictions have adopted mechanisms for the involuntary medication of defendants to restore competency to stand trial. These procedures attempt to balance the liberty and privacy rights of the accused against the government's responsibility to ensure timely prosecution and fair trial. The question of which medications are most appropriate for this goal, however, remains open.

Effect of 3D-Printed Models on Cadaveric Dissection in Temporal Bone Training.

Objective: Mastoidectomy is a cornerstone in the surgical management of middle and inner ear diseases. Unfortunately, training is challenged by insufficient access to human cadavers. Three-dimensional (3D) printing of temporal bones could alleviate this problem, but evidence on their educational effectiveness is lacking.

What Ever Happened to Nostalgia (the Diagnosis)?

Nostalgia and homesickness are not currently regarded as mental disorders. The psychic pain associated with longing to return home had been considered a mental disorder for centuries, especially in Europe, where it was a sign of moral weakness between nations. Nostalgia's effects on American Civil War soldiers-anxiety, depression, and sleep and appetite disturbances, for example-were described by clinicians and linked to significant morbidity and mortality.

Arsenic, Familicide, and Female Physiology in Nineteenth-Century America.

Sarah Jane Whiteling was accused of fatally poisoning her husband and two children in Philadelphia in 1888. The case prompted public outrage over the appearance that Ms. Whiteling's motive was to collect life insurance.

Insanity: A Legal and Cinematic Diagnosis.

The term "insanity" has been retired from medical nomenclature for about 100 years. Formerly interchangeable with the legal term, implying unsoundness of mind, it persists as a legal determination, mainly in criminal matters. However, the most prevalent uses of "insanity" are in colloquial speech and media.

The Four Horsemen of the 'Omicsalypse': ontology, replicability, probability and epistemology.

Much of modern genomics and the other 'omics' that tag along, assert that the causal bases of biomedical outcomes are genomically enumerable lists whose effects are predictable with 'precision', extensible from samples to all, and enabled by ever-greater hypothesis-free data accumulation. The assertion rests on fundamental, if often implicit assumptions, that (1) the phenomena are based on underlying law-like biological causation, and, therefore, are (2) replicable and (3) even if not deterministic, have specifiable, stable, essentially parametric, probabilities, all of which (4) essentially equates induction with deduction, enabling asymptotically accurate prediction based on past observation. These glowing promises are the four horsemen of a genocentric 'Omicsalypse'.

Genetic Pointillism versus Physiological Form.

Genomics has revealed that biological causation is subtler than a pointillist dream of essentially enumerable, additive precision predictability from constitutive DNA sequences. Instead, data have revealed a higher-dimension interactive genomic landscape, that is more fundamentally fluid than precision predictability requires. This raises epistemological and ontological issues that, if properly accepted, may help leverage new ideas.

America's First Defense and the Origin of the Black Rage Syndrome.

The 1843 verdict led to reformulation of the British criminal insanity standard, which American jurisdictions noted. In 1846, New York State tried William Freeman for slaying several members of the Van Nest family at their home near Auburn, New York. Mr.

Consent for Intimacy Among Persons With Neurocognitive Impairment.

The right to bodily self-determination has a firm foothold in American jurisprudence and legislation. Since the early 20th century, courts have consistently upheld individuals' rights to govern their bodies, citing the constitutional right to privacy and importance of individual autonomy. After these decisions, the advance directive has become an essential way to express personal preferences after incapacity for decision-making, especially in end-of-life scenarios.

Lifestyle Medicine-Focused Shared Medical Appointments to Improve Risk Factors for Chronic Diseases and Quality of Life in Breast Cancer Survivors.

Objectives: Poor lifestyle choices play a significant role in the development and progression of preventable chronic diseases, including cancer. In this study, we evaluate the effectiveness of a comprehensive lifestyle medicine intervention on chronic disease risk factors and quality of life in breast cancer survivors.

Design: This is a retrospective review of a clinical program from January 2016 to July 2017.

Assignment of culpability to animals as a form of abuse: Historical and cultural perspectives.

How the law regards animals reflects cultural trends that have varied widely from antiquity to the present. This article argues that cultural views of animals have shaped laws, attitudes, and practices worldwide. Whereas ancient (biblical and Mesopotamian) practices turned on economics, medieval concepts of animal culpability aligned with Christian beliefs of the primacy of humans.
