Evaluating the Public's Interest in Testicle Tanning: Observational Study.

Background: A new and potentially dangerous health trend, testicle tanning, received extensive media attention following a popular television program where a health and fitness influencer touted that testicular tanning increases testosterone levels. It has been shown that the public has a particular interest in tanning wellness trends; thus, given the vague nomenclature of the practice, the abundance of misleading information and support for using UV light by other health influencers may lead to an increase in men exposing themselves to UV radiation and developing associated complications.

Objective: The aim of this paper is to evaluate the public's interest in testicle tanning.

Unintended insulin delivery using Omnipod DASH during a high-altitude flight.

Insulin pumps are an important tool in the management of type I diabetes mellitus. Omnipod DASH is a tubeless insulin pump that delivers insulin through customisable basal rate and bolus amounts. There is no data available to date on how this insulin pump delivery system is influenced by changes in atmospheric pressure during flight at high altitudes.

Granuloma annulare on the palms.

We present the case of a 72-year-old man with a one-week history of a red rash on the palms of both hands. A 4mm punch biopsy revealed interstitial granulomatous inflammation within the dermis and a colloidal iron stain showed increased dermal acid mucin. Immunohistochemical staining for CD68 confirmed the presence of abundant histiocytes within the dermis.

Cutaneous Plasmacytosis Associated with Ehrlichiosis in an African-American Patient.

Cutaneous plasmacytosis is a rare disease that presents clinically with multiple red-brown papules and plaques with minimal to no epidermal change. Histopathologic findings include a perivascular dermal infiltration of polyclonal plasma cells. The etiology of cutaneous plasmacytosis is unknown, but hypothesized to be due to persistent or repeated antigenic stimulation.

Analysis of 10 Years of Diagnostic Radiology Match Data: Notable Changes and Their Potential Implications.

Rationale And Objectives: Identification of shifts in match metrics, such as applicant volumes, match rates, and interview patterns, stands to inform and empower both applicants and programs participating in the NRMP residency match. Residency programs rarely publish their internal data. Accordingly, we employed publicly available resources to evaluate changes in such metrics for the diagnostic radiology match from 2008 to 2018.

Light-Dependent Electrical Activity in Sea Urchin Tube Feet Cells.

Sea urchins can detect and respond to light, and many species of sea urchins are negatively phototaxic. Light detection is hypothesized to occur via photoreceptors located on sea urchin tube feet, and opsins have been detected in tube feet, spines, and the test. However, the molecular mechanisms underlying light detection are, for the most part, unknown.

Pharmacological Disruption of Sea Urchin Tube Foot Motility and Behavior.

The understanding of the molecular basis of sea urchin behavior and sensory and motor systems lags far behind that of many other animal species. To investigate whole-animal behavior pharmacologically, we first demonstrated that immersion in drug solution is an effective drug administration route for sea urchins, whereas oral drug administration was found to be ineffective. Although intracoelomic injection was found to be effective at administering drugs, it was also found that injection itself can disrupt normal sea urchin behavior.
