Holley, MD, et al.

We present a case of a heterotopic pregnancy diagnosed by point-of-care ultrasound (POCUS) in a woman presenting with lower abdominal pain, who had a documented normal first trimester ultrasound the day prior to presentation.

Polito, MD, et al.

We present a case of a 29-year-old man with a pacemaker who presented with new, deep symmetric T-wave inversions caused by cardiac memory.

Earle, MD, et al.

We report a case of a patient with type II diabetes mellitus who presented with euglycemic diabetic ketoacidosis in the setting of concurrent use of canagliflozin, a sodium-glucose transporter-2 (SGLT-2) inhibitor, and strict adherence to a low-carbohydrate ketogenic diet for weight control.

Rossi, MD, et al.

We report one of few documented cases of a severe anaphylactic reaction with angioedema to polyethylene glycol (PEG).

Gallagher, MD, et al.

A 36-year-old man presented to the emergency department for worsening dyspnea and chest pain. Point-of-care echocardiography demonstrated a mobile oscillating mass on the aortic valve with poor approximation of the valve leaflets, suggesting aortic valve insufficiency secondary to IE as the cause of acute heart failure. The patient underwent emergent aortic valve replacement within 24 hours.

Worden, BS, et al.

We present the case of a 50-year-old male with a spontaneous, atraumatic fracture of an elongated styloid process associated with hematoma formation and radiological findings of airway impingement.

Chitty, DO, et al.

We present a case of a patient with chronic back pain who was found to have a gastric antral mass as the etiology of her pain. The patient proceeded to have a partial gastrectomy with complete surgical excision of her early-stage gastric cancer, after which her chronic back pain resolved.

Antolick, MD, et al

We present a case of a nine-year-old child arriving at the emergency department after exposure to chlorine gas. Complete recovery from his symptoms occurred rapidly with the administration of nebulized sodium bicarbonate.

Le, MD, et al.

We present a case of an 88-year-old male with chronic lymphocytic leukemia (CLL) and suspected blast crisis who was found to have elevated serum potassium levels without other manifestations of hyperkalemia and eventually was determined to have pseudohyperkalemia due to white cell fragility.

Zitelny, MD, et al.

High-pressure injection injuries have been chronicled for decades.1 These injuries often affect distal extremities as they are most commonly involved in workplace accidents.1 However, we discuss a young male with a paint-gun injection injury to his face.

Wallace, DO, et al.

This case demonstrates a 27-year-old female who presented to the emergency department with a non-tender, compressible, left-sided neck mass that enlarged with valsalva and talking, and intermittent paresthesias.

Garcia de Alancar, MD, et al.

We report the case of a 38-year-old woman gravida 2, para 0, abortion 1 with type 1 diabetes who had euglycemic diabetic ketoacidosis and review the literature on DKP, with a focus on diagnosis, treatment, and monitoring of the mother and fetus.

Ogle, MD, et al.

We describe a case of bilateral patellar tendon rupture that presented after minor trauma, and had the diagnosis confirmed at the bedside by point-of-care ultrasound. Physicians caring for patients with orthopedic injuries should be familiar with the use of ultrasound to diagnose tendon ruptures.

Quesada, MD, et al.

A 10-year-old male vaccinated against varicella had developed left-sided rashes on his thoracic region in single dermatomal distribution, which is consistent with herpes zoster. Although herpes zoster is uncommon in children, especially with the current vaccination regimen, this case report serves as a reminder to consider it in one’s differential diagnoses, even in the immunocompetent, fully immunized pediatric patient.

Sampson, MD, et al.

A 27-year-old female presented to the emergency department with sudden onset shortness of breath. A diagnosis of bilateral catamenial pneumothoraces was made following chest radiograph.

Kessler, DO, et al.

We have described a low energy case of bilateral luxatio erecta and the reduction method used and the continued instability following successful reduction under procedural anesthesia.

Lee, MD, et al.

A 29-year-old man presented with a carboxyhemoglobin (COHb) level of 29.8%. He was treated with HFNC, and COHb levels declined to 5.4% in 230 minutes. Given several theoretical advantages of HFNC relative to NRB, HFNC is a potential option for use in the treatment of CO poisoning.

Mercurio, MD, et al.

Here we discuss a case of early neurosyphilis and new HIV diagnosis in a 27-year-old previously-healthy trans woman presenting for the second time with progressive, ascending weakness and cranial nerve VI palsy.

Ershad, MD, et al.

Formic acid, when combined with sulfuric acid, gets dehydrated to form carbon monoxide (CO). A 27-year-old female was found unconscious inside a car, next to a container with a mixture of sulfuric acid and formic acid.

Romero, MD, et al.

A 76-year-old male developed acute ischemic stroke symptoms. Systemic alteplase was administered and he showed clinical improvement.

O’Donnell, MD, et al.

Pediatric paraspinal abscesses are not well documented in the literature. We report a case of a two-year-old female presenting with fevers, lower back pain, and decreased oral intake ultimately diagnosed with isolated lumbar paraspinal abscess.

Kellar, MD, et al.

There have been a number of case reports discussing the association of patients on bisphosphonates who suffer a non-traumatic or a low-energy mechanism of injury atypical of subtrochanteric fractures. The purpose of this case report is to raise awareness of this potential side effect and provide increased clinical suspicion for this rare type of fracture.

Hoffman, MD, MS, et al.

We present a rare case of cesarean scar ectopic pregnancy as diagnosed by transvaginal ultrasonography. Cases such as this are rare, but they are becoming more commonly detected with the growing frequency of cesarean sections, improving technology, and provider proficiency with point-of-care ultrasound.

Herold, DO, et al.

Infectious mononucleosis is primarily caused by Epstein-Barr virus (EBV) and is a common diagnosis made in emergency departments worldwide. Subclinical and transient transaminase elevations are a well-established sequela of EBV.

Meester, MD, et al.

We present a case of LAGB-associated discitis and osteomyelitis 20 years after placement and examine the current literature on the complication rates of bariatric surgery along with the rare injuries following LAGB placement.

Lajeunesse, MD, et al.

In this case, we present a rare case of unilateral THPP. Such a presentation is relevant to emergency physicians as it mimics a stroke or transient ischemic attack and should be considered on the differential for unilateral neurologic deficits.
