RESUMO
Ewing sarcoma is a tumor primarily affecting children and young adults, and usually affects long bones. Extraosseous Ewing sarcoma (EES) is a rare primary tumor of soft tissues. We present a case of abdominal EES with metastasis to thoracic cavity, which presented as abdominal pain and vomiting in a 21-year-old previously healthy gentleman.

Introduction: Ventilator Associated Pneumonia (VAP) is associated with significant cost, morbidity, and mortality. There is limited data on the incidence of VAP, appropriate antibiotic timing, and the impact of multidrug resistant VAP in intubated Coronavirus disease-19 (COVID-19) patients. Methods: A retrospective study was conducted at 2 tertiary urban academic centers involving 132 COVID-19 patients requiring invasive mechanical ventilation (IMV). The epidemiology of VAP, the impact of prior empiric antibiotic administration on the development of Multidrug Resistant Organism (MDRO) infections, and the impact of VAP on patient outcomes were studied. Results: The average age of the patients was 60.58% were males, 70% were African-Americans and two-thirds of patients had diabetes, hypertension, or heart disease. The average Body Mass Index (BMI) was 32.9. Forty-one patients (27%) developed VAP. Patients with VAP had a significantly higher Sequential Organ Failure Assessment (SOFA) score prior to Intensive Care Unit (ICU) admission. Sixty percent received empiric antibiotics before initiation of IMV, mostly on hospital admission, and 81% received empiric antibiotics at the time of intubation. The administration of empiric antibiotics was not associated with a higher prevalence of VAP. The prevalence of VAP was 22 per 1000 days on ventilation. No difference in mortality was seen between VAP and non-VAP groups at 49% and 57% respectively (p = 0.4). VAP was associated with increased ICU length of stay (LOS), 30 vs. 16 days (p < 0.001), and longer hospital LOS 35 vs. 17 days (p < 0.001). 40% of VAPs were caused by MDROs. The most common organism was Staphylococcus aureus (28%), with almost half (48%) being methicillin resistant Staphylococcus aureus (MRSA). Conclusion: VAP was a common complication of patients intubated for COVID-19 pneumonia. Most patients received empiric antibiotics upon the hospital and/or ICU admission. There was a 40% incidence of multidrug resistant pneumonia. Patients who developed VAP had almost twice as long hospital and ICU LOS.

Platypnea-orthodeoxia syndrome (POS) is defined by dyspnea and deoxygenation due to a change in body position from lying down to an upright position. We present a case of a large right atrial (RA) thrombus likely due to a right coronary artery fistula in a patient with a patent foramen ovale (PFO). On imaging, the thrombus was thought to be an atrial myxoma involving the tricuspid valve; however, after surgical excision and histopathological analysis, it was noted to be a cystic thrombus. Red-brown material along with vascular elements was noted on histopathology. Post-surgery, the patient was critically ill and died due to severe tricuspid regurgitation (TR) and hypotension despite using a right ventricle assist device and multiple vasopressors. Reverse Lutembacher syndrome (RLS) is defined as a triad of tricuspid stenosis (TS), elevated RA pressure, and right-to-left atrial shunting. The location of the mass and positional changes could be causing transient RLS from positional TS and interatrial shunting via the PFO causing POS. Cardiac magnetic resonance imaging can help differentiate between intracardiac masses. T1 and T2 signal characteristics and differences in contrast enhancement can help differentiate between a thrombus and a tumor. Treatment options include anticoagulation, thrombolysis, and thrombectomy. If severe TR occurs after surgery, treatment modalities such as caval valves could be an option in the future. Extracorporeal membrane oxygenation to provide right ventricle support in such cases could be considered.
RESUMO
The impact of COVID-19 was felt across the globe when it first emerged in December 2019. However, within a year, there was a new hope with the development and approval of mRNA vaccines. The Comirnaty and Pfizer-BioNTech BNT162b2 mRNA vaccine showed an efficacy of 95 percent in preventing COVID-19 disease. However, subsequent studies conducted on immunocompromised hosts showed the efficacy to be significantly lower than the initial reported 95 percent, making these patients prone to COVID-19 disease despite the initially recommended two doses. On Sept. 22, 2021, a third dose was approved for immunocompromised hosts. In this article, we report the case of a 67-year-old female with overlap connective tissue disease on mycophenolate mofetil who had a prolonged hospital course because of severe COVID-19 disease complicated by pulmonary embolism despite receiving three doses of the BNT162b2 mRNA vaccine.

Stimulant medications like amphetamines have been associated with various cardiovascular complications like coronary artery spasm, coronary dissections and thrombus formation, the pathophysiology of which is theorized to be the endothelial damage induced by the medication and the inflammatory cascade that follows. We report a case of 52-year-old male on lisdexamfetamine, a newer stimulant agent used for attention deficit hyperactivity disorder (ADHD) who presented with sudden chest pain and ECG changes concerning for myocardial infarction and mildly elevated troponins. However, coronary angiogram showed no obstructive coronary artery disease and there was spontaneous resolution of his symptoms and ECG changes.

Foreign body (FB) aspiration can present with acute life-threatening asphyxiation to recurrent infections with lung damage. Although most esophageal FBs pass spontaneously, sharp ones can get embedded requiring treatment. Tracheobronchial FBs and hypopharyngeal FBs are occasionally seen as well. We present a case of an oropharyngeal FB presenting with signs of stroke, pulmonary embolism, pulseless, and causing airway compression and extubation failure. Old age and neurocognitive disability are important predisposing factors of FB airway obstruction (FBAO), with food being the most common cause. The classic triad of cough, dyspnea, and cyanosis is seen in only a small percentage of patients with FBAO. Laryngeal edema, soft tissue collapse, and laryngospasm are among the common causes of upper airway obstruction and extubation failure. Laryngeal traumatism that can occur during emergency intubations can cause post-extubation stridor that can be treated with corticosteroids. Dentures and blood have been reported to cause post-extubation complications but oropharyngeal FB causing airway compression and leading to extubation failure has not been reported before. We recommend FB to be considered in the differential diagnosis of immediate hypoxia and extubation failure regardless of the history of a witnessed aspiration event as it is an easily fixable cause and can be missed in the initial history of presentation. A high degree of suspicion for this should be maintained as it is easy to miss. Computed tomography of the neck can aid in the diagnosis.
RESUMO
BACKGROUND: Coronavirus disease 2019 (COVID-19) has become a leading cause of morbidity and mortality worldwide. One of the major complications of COVID-19 infection is the hypercoagulability state. Cardiac thrombi and venous thromboembolism (VTE) have been documented with severe COVID-19 infection. We present a case of large right atrial (RA) thrombus in transit incidentally diagnosed following a mild COVID-19 in a previously vaccinated patient. CASE SUMMARY: An 85-year-old male presented to the emergency department two weeks following resolution of a mild COVID-19 infection due to an incidentally discovered large RA thrombus. Computed tomography with angiography of the chest was positive for acute pulmonary thromboembolic disease with large clot burden and findings consistent with right heart strain. The patient remained hemodynamically stable and was successfully managed with anticoagulation. CONCLUSION: RA thrombi and VTE can occur in patients with mild COVID-19 infection and in the setting of full COVID-19 vaccination. Echocardiography is a useful imaging modality in this patient population.

Invasive pneumococcal disease occurs in high-risk patient population which includes patients with asplenia and primary hypocomplementaemia. Pneumococcal sepsis can rarely cause disseminated intravascular coagulation (DIC) and intravascular thrombosis of small and medium sized vessels called purpura fulminans which is associated with a high mortality rate. We present the case of an immunocompetent woman in her 50s with an intact spleen who presented with septic shock from Streptococcus pneumoniae bacteraemia. Her hospital course rapidly progressed to multiorgan dysfunction, DIC and purpura fulminans. She was treated aggressively with broad spectrum antibiotics, coagulation factor replacement, multiple vasopressor support, renal replacement therapy and mechanical ventilator support. Despite aggressive measures, she succumbed to the multiorgan failure.

There has been an observance of increased occurrence of malignant lymphomas in patients with rheumatoid arthritis (RA). The increased risk of lymphoproliferative disorders has been linked to the severity of RA disease activity, the use of disease-modifying agents like methotrexate and certain genetic links between RA and lymphomas. This article outlines the case of an 88-year-old gentleman with a 13-year history of seropositive rheumatoid arthritis on methotrexate who presented with ankle pain and was subsequently found to have diffuse large B-cell lymphoma on further workup.
RESUMO
Henoch-Schönlein purpura (HSP) is a self-limited vasculitis that affects children and the preadolescent population. It is characterized by the deposition of immunoglobulin A immune complexes in tissues leading to palpable purpura, abdominal pain, arthritis, and nephropathy. When it occurs in adults, the clinical manifestations are the same; however, adults present with more significant renal involvement. While abdominal pain is the most common gastrointestinal (GI) manifestation, it can also present with GI bleeding, intussusception, bowel ischemia, and bowel perforation. Here, we report the case of a 22-year-old gentleman who presented with nonspecific GI complaints such as nausea, vomiting, and loose stools. He was later found to have terminal ileitis preceding the onset of rash, the biopsy of which confirmed HSP. Terminal ileitis is a rare GI manifestation of HSP and is not very commonly reported in the literature.
RESUMO
Solitary fibrous tumours (SFTs) are rare mesenchymal tumours that are mostly seen in the pleura. Lately, they have also been described in other locations. Recent discovery of the NAB2-STAT6 fusion gene which is specific for SFTs has led to an accurate diagnosis of SFTs. The occurrence of SFTs in the mesentery is very rarely reported in the literature. We report a case of a 63-year-old female who presented with abdominal pain, rectal bleeding and Fusobacterium bacteraemia, who was ultimately found to have a mesenteric SFT.
