Clinical Practice and Cases in Emergency Medicine

INTRODUCTION: Rectus abdominis muscle strains are common and can be debilitating in both professional and amateur athletes who engage in strenuous activity. CASE REPORT: We report a rare case of rectus abdominis muscle tear in an amateur bodybuilder diagnosed by point-of-care ultrasound (POCUS) in the emergency department (ED). The patient had presented to the ED three separate times after strenuous exercise, received costly diagnostic workups, and ultimately was diagnosed on the third visit with grade 2 bilateral rectus abdominis tear...

INTRODUCTION: Spontaneous splenic rupture is an extremely rare complication of infective endocarditis. CASE REPORT: We present a case of a 56-year-old immunocompetent female with porcine bioprosthetic mitral valve replacement, automated implanted cardioverter-defibrillator, and atrial fibrillation on apixaban who was found to have in-hospital atraumatic splenic rupture complicating infective endocarditis with Haemophilus parainfluenza. The rupture was treated successfully by endovascular embolization...

INTRODUCTION: Unlicensed cosmetic procedures, which come at increased risk of infection and potential surgical complications, have introduced new challenges in healthcare. Physicians should be aware of presentations that may arise secondary to these procedures. CASE REPORT: We describe a case in which a previously healthy, 28-year-old female presented with new-onset seizures and acute respiratory distress syndrome (ARDS) in the setting of a recent cosmetic procedure with silicone injections to the gluteal region...

INTRODUCTION: The asp caterpillar ( Megalopyge opercularis ) is endemic to the southeastern United States, with most sightings in Florida, Texas, and Louisiana. A few hundred caterpillar envenomations are reported annually with most cases occurring in July-November. Asp caterpillars have hollow spines along their backs that contain venom. Contact with these spines is what produces the characteristic "sting" resulting in contact dermatitis and a localized hypersensitivity reaction collectively referred to as lepidopterism...

INTRODUCTION: Ovarian artery aneurysm is a rare diagnosis, primarily associated with late pregnancy and the postpartum period. It can cause life-threatening hemorrhage when ruptured. Even more rare are ovarian artery aneurysms in postmenopausal women. CASE REPORT: We present a case of a postmenopausal female presenting to the emergency department with flank pain. Point-of-care ultrasound showed free fluid in the abdomen. She was diagnosed with an ovarian artery aneurysm on computed tomography angiography and treated successfully with embolization...

INTRODUCTION: Severe metabolic alkaloses are relatively rare but can carry a high mortality rate. Treatment involves supportive care and treatment of underlying causes. CASE REPORT: A 55-year-old male dependent on a gastrojejunostomy tube presented to the emergency department for altered mental status. The patient had metabolic alkalosis, electrolyte abnormalities, and prolonged QT interval on electrocardiogram. Examination and history revealed that chronic drainage of gastric fluid via malfunctioning a gastrojejunostomy tube resulted in profound alkalosis...

INTRODUCTION: Severe hypernatremia is a critical situation, and when coupled with intravascular depletion and hypotension can create a treatment dilemma. CASE REPORT: We present the case of a medically complex patient who had gradually worsening alteration of mental status and mean arterial pressures in the 50s on presentation to the emergency department. CONCLUSION: Final diagnoses included severe hypernatremia and hypovolemic shock secondary to poor oral intake...

INTRODUCTION: Peritonsillar abscesses form between the tonsillar capsule, the superior constrictor, and palatopharyngeus muscles. Physicians traditionally make this diagnosis clinically; however, ultrasound allows clinicians to further identify and differentiate between peritonsillitis, peritonsillar abscess, and phlegmon formation. By increasing both the sensitivity and specificity, ultrasound improves the diagnostic accuracy for patients with peritonsillar abscesses. This case demonstrates the utilization of ultrasound in peritonsillar abscesses and the application of point-of-care ultrasound (POCUS) in identifying complications of procedures used for treatment in the emergency department (ED)...

INTRODUCTION: Visceral arterial aneurysms and pseudoaneurysms are rare but dangerous pathologies, with reported incidence of 0.01-0.2% of the worldwide population, as found on autopsy. Pancreaticoduodenal artery pathology accounts for approximately 2% of all visceral aneurysms; it is commonly caused by chronic inflammatory processes, such as pancreatitis or adjacent pseudocysts. Morbidity and mortality commonly result from rupture of the aneurysm itself, leading to life-threatening hemorrhage into the peritoneum or gastrointestinal tract...

INTRODUCTION: Cerebrovascular accidents rarely occur in children; the incidence of ischemic stroke in patients <16 years of age is between 0.6-7.9/100,000. However, they are the fourth most common cause of acute neurological deficits in the pediatric population, and possible cases should be evaluated with a high index of suspicion to ensure timely intervention. CASE REPORT: We describe a previously healthy 17-year-old male who presented to the pediatric emergency department with a left facial droop and hemiparesis consistent with a stroke...

INTRODUCTION: Vision loss is a symptom found frequently in patients presenting to the emergency department (ED). Central retinal artery occlusion (CRAO) is an uncommon yet time-sensitive and critical cause of painless vision loss in which delayed diagnosis can lead to significant morbidity. Emergency medicine literature documents the ability to diagnose a CRAO using ultrasound by identifying the hyperechoic thrombus-coined the retrobulbar spot sign. CASE REPORT: We present the case of a patient presenting with painless monocular vision loss for which CRAO was diagnosed in the ED using point-of-care ultrasound enhanced by the utilization of serial Doppler examinations as well as calculation of the central retinal artery resistive index...

INTRODUCTION: Diabetic ketoacidosis (DKA) is a common diagnosis in the emergency department (ED). However, one must consider other causes for acid-base disturbances when the pattern is not consistent with typical presentation. CASE REPORT: A 52-year-old female with a history of insulin-dependent diabetes mellitus type 2 presented to the ED with abdominal pain, nausea, and vomiting for three days. Her diagnostic workup revealed diabetic ketoacidosis but with concurrent metabolic alkalosis...

INTRODUCTION: Implantable cardioverter-defibrillator (ICD) lead perforation through the myocardium may result in chest pain and electrocardiogram (ECG) changes concerning for ST-segment elevation myocardial infarction. The clinical context of the ECG aids in appropriate management. CASE REPORT: We report the case of a 71-year-old woman experiencing chest pain after an ICD placement two weeks earlier. On presentation, she exhibited ST-segment elevation on her ECG...

INTRODUCTION: Ferric derisomaltose is the newest available parenteral iron formulation. Studies have demonstrated a good safety profile with improved tolerability compared to alternative parenteral iron formulations. To date there have been no reported acute, life-threatening cardiac events associated with ferric derisomaltose. CASE REPORT: An 86-year-old male who had previously tolerated routine iron infusions received a first dose of ferric derisomaltose at an outpatient infusion clinic...

INTRODUCTION: Mesenteric volvulus is a rare cause of abdominal pain and bowel obstruction in elderly patients. When a mesenteric volvulus occurs in adult patients, the symptoms are often non-specific, which contributes to delays in diagnosis. CASE REPORT: We present a case of a 75-year-old female who presented with non-specific abdominal pain. The rare whirlpool sign on computed tomography identified a mesenteric volvulus as the cause of small bowel obstruction...

INTRODUCTION: Spontaneous esophageal rupture, or Boerhaave syndrome, and upside-down stomach are rare pathologies associated with grave sequelae. Boerhaave syndrome can have a mortality rate as high as 44%. Upside-down stomach accounts for less than 5% of hiatal hernias and can lead to incarceration and volvulus. CASE REPORT: An 80-year-old woman presented to the emergency department with sudden onset, severe epigastric pain. Physical examination revealed normal vital signs with mild epigastric tenderness...

INTRODUCTION: Accurate diagnosis of traumatic arthrotomy of the knee (TAK) is critical for patients presenting to the emergency department (ED) to ensure timely treatment. Current diagnostic modalities including plain radiography, computed tomography (CT), and the saline load test (SLT) have advantages and disadvantages. Point-of-care-ultrasonography (POCUS) offers a possible timely, low-cost, and efficient alternative method of diagnosing TAK. In this case series we present three cases where POCUS was used to diagnose TAK in the ED...

Chest pain is a common presentation to the emergency department (ED) that can be caused by a multitude of etiologies. It can be challenging to differentiate life-threatening conditions from more benign causes. A 54-year-old woman presented to the ED complaining of chest pain with dyspnea in the setting of recent blunt trauma. This case offers a thorough yet practical approach to the diagnostic workup of chest pain with dyspnea in the ED setting. The surprising final diagnosis and case outcome are then revealed...
