Dysuria, Rebound Tenderness, and a Palpable Mass-A Ticking Time Bomb.

A 37-year-old male presented to the emergency department with the complaint of periumbilical abdominal pain, radiating to just above pubic symphysis. The patient reported that the pain was worse with urination and associated with chills and nausea. This case reports discusses the Emergency Department (ED) course and subsequent treatment of a patient found to have an infected urachal cyst, a previously asymptomatic embryological anomaly in an otherwise healthy middle-aged adult male.

Step-Down Task Identifies Differences in Ankle Biomechanics Across Functional Activities.

Currently, there is no clinical exam to evaluate ankle frontal plane kinematics. The purpose of this study was to determine whether individuals identified as "lateral" landing during a video-recorded step-down task have differences in ankle inversion as measured with 3-dimensional motion capture during walking, step-down, and jump-landing tasks compared to individuals identified as "non-lateral". Fifty-seven recreationally active adults completed the descriptive laboratory study.

Acute lateral ankle sprain to chronic ankle instability: a pathway of dysfunction.

Lateral ankle sprains (LAS) have been reported as one of the most common musculoskeletal injuries observed in sports and in individuals who are recreationally active. Approximately 40% of individuals who sustain a LAS develop a condition known as chronic ankle instability (CAI). Years of research has identified numerous impairments associated with CAI such as decreases in range of motion (ROM), strength, postural control, and altered movement patterns during functional activities when compared to individuals with no LAS history.

A Comprehensive Characterization of Parameters Affecting High-Frequency Irreversible Electroporation Lesions.

Several focal therapies are being investigated clinically to treat tumors in which surgery is contraindicated. Many of these ablation techniques, such as radiofrequency ablation and microwave ablation, rely on thermal damage mechanisms which can put critical nerves or vasculature at risk. Irreversible electroporation (IRE) is a minimally invasive, non-thermal technique to destroy tumors.
