Real-time Point-of-care Ultrasound for the Diagnosis and Treatment of Testicular Torsion.

: Testicular torsion is a surgical emergency that needs prompt diagnosis and treatment. Point-of-Care ultrasound (POCUS) can not only establish the diagnosis but also guide the Emergency Physician in evaluating the response to manual detorsion. : We describe the case of a 13-year-old male who presented with acute scrotal pain.

Diagnosing Achilles Tendon Rupture with Ultrasound in Patients Treated Surgically: A Systematic Review and Meta-Analysis.

Background: Achilles tendon rupture is a common injury with increasing incidence due to the rising popularity of high-velocity sports, continued physical activity of the aging American population, and use of fluoroquinolones and steroid injections. The diagnosis can often be missed or delayed, with up to 20% misdiagnosed, most commonly as an ankle sprain.

Objective: The aim of our study was to systematically evaluate the reported sensitivity, specificity, and likelihood ratios of ultrasound for detecting Achilles tendon rupture in patients who were treated surgically.

Bilateral Retinal Detachments in a Healthy 22-year-old Woman After Moderna SARS-COV-2 Vaccination.

Background: Although uncommon, retinal detachments are medically urgent and can result in permanent vision loss if untreated. Bilateral retinal detachments in healthy individuals are even more rare. In addition, there are no cases to date of retinal detachment associated with either coronavirus disease 2019 (COVID-19) or after receiving the Moderna (mRNA-1273) severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) vaccine.

A Case of Covid-19 Diagnosed at Home With Portable Ultrasound and Confirmed With Home Serology Test.

Background: The coronavirus disease 2019 (COVID-19) pandemic has pushed us to find better ways to accurately diagnose what can be an elusory disease, preferably in a way that limits exposure to others. The potential for home diagnosis and monitoring could reduce infectious risk for other patients and health care providers, limit use of finite hospital resources, and enable better social distancing and isolation practices.

Case Report: We report a case of an otherwise healthy emergency physician diagnosed with COVID-19 at home using portable ultrasound, pulse oximetry, and antibody testing.

Phenytoin Toxicity After Transjugular Intrahepatic Portosystemic Shunt (TIPS).

Background: Transjugular intrahepatic portosystemic shunt (TIPS) alters portal blood flow and may impact drug metabolism and bioavailability. However, little evidence has been published to provide guidance on medication alterations after TIPS procedures.

Case Report: We report a patient who developed phenytoin toxicity requiring a prolonged readmission after a TIPS procedure.

Kikuchi Disease: A Case Report.

Background: Kikuchi disease, also known as Kikuchi-Fujimoto disease, is a rare, benign cause of cervical lymphadenitis. It is characterized by painful cervical lymphadenopathy with fevers, leukopenia, and an elevated erythrocyte sedimentation rate. It is diagnosed by obtaining a biopsy specimen from a lymph node that shows characteristic histopathologic findings.
