RESUMO
BACKGROUND: Aortic dissection is a rare but well-known life-threatening disease that classically presents with tearing chest pain radiating to the back yet can have deceiving clinical presentations. CASE REPORT: A 54-year-old man with a history of hypertension presented to the emergency department with mild shortness of breath without chest pain. Point-of-care ultrasound (POCUS) detected diffuse B-lines, a dilated aortic root, aortic regurgitation, and pericardial effusion. A computed tomography angiogram confirmed a Stanford type A aortic dissection with diffuse alveolar hemorrhage (DAH), a rare complication of type A aortic dissection involving the posterior aortic wall with extension into the main pulmonary artery. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Acute aortic dissection can present with a wide range of clinical manifestations with a high mortality rate for patients with an untimely diagnosis. Although an intimal flap within the aortic lumen is the characteristic finding on ultrasound, additional POCUS findings of a pericardial effusion, aortic regurgitation, and a dilated aortic root may be seen with proximal dissections. Diffuse B-lines on thoracic POCUS, although commonly associated with pulmonary edema in decompensated heart failure, can be seen in patients with DAH which has a multitude of etiologies, including aortic dissection.

This is a case report of a 55-year-old woman with a past medical history of hypertension who presented to the emergency department with upper lip and cheek swelling isolated to the right side of her face. She was on lisinopril for several years and had never had an episode of swelling in the past. Her vital signs were stable. However, on reassessment, the patient's right sided swelling progressed to the entire upper lip and she complained of swelling in her submandibular space. Although no swelling was appreciated to the submandibular space on physical exam, and the patient still did not have any signs or symptoms of respiratory distress, the decision was made to use a fiberoptic laryngoscope to evaluate her airway. Fiberoptic laryngoscope showed noticeable laryngeal edema which did not improve after treatment, and the patient was admitted to the medical intensive care unit for close airway observation. This case highlights the use of fiberoptic laryngoscope by emergency physicians in the evaluation of patients with relatively benign appearing angioedema. Topics: ACE-I, angioedema, fiberoptic laryngoscope, laryngeal edema, tranexamic acid.
RESUMO
Nontuberculous mycobacteria (NTM) are a rare cause of prosthetic joint infection (PJI) that is documented to affect immunocompromised patients primarily. In this case report, we describe an immunocompetent patient with a rare case of PJI caused by Mycobacterium moriokaense after a total knee replacement. This patient is the eighth reported case of PJI caused by NTM and the first reported case in an immunocompetent individual. Because PJI caused by NTM is rare and difficult to treat, it is essential to include it in the differentials during initial workup of suspected PJI, especially in the context of negative preliminary bacterial cultures.
RESUMO
As of May 14, 2020, the World Health Organization has reported approximately 4.3 million cases of the novel Coronavirus Disease (COVID-19) with approximately 294,046 deaths worldwide [1]. Solid organ transplant recipients who are on chronic immunosuppressants fall within a special population of COVID-19 patients since they are more susceptible to complications secondary to COVID-19. Currently, we do not have data on treating COVID-19 patients with solid organ transplants with tocilizumab, an interleukin-6 (IL-6) inhibitor. We report a case of COVID-19 in a patient with a kidney and liver transplant and discuss the early use of tocilizumab to prevent the cytokine storm and attempt to reduce the likelihood of progression to Acute Respiratory Distress Syndrome (ARDS). In addition, we present other COVID-19 related transplant cases reported in the literature outlining the presenting clinical signs and outcomes.
