Axillary Lymphadenopathy associated with COVID-19 vaccination: updates and recommendations.

Lymphadenopathy associated with vaccination has been documented as complicating the evaluation of metastatic malignancy (Bychokovsky & Lin, 2017) (Choi, Ko, Han, J, & Kang S, 2009) (Mohseni, et al., 2014). In the past this was a limited finding, primarily documented in association with smallpox and H1N1 vaccination (Mingos, Howard, Giacalone, Kozone, & Jacene, 2016) (Fry, et al., 2021) (Panagoitidis, Exarhos, Housianakou, Bournazos, & Datseris, 2010).The advent of the novel mRNA vaccine for Covid-19 in December of 2021, and subsequent large scale vaccination effort, has resulted in a marked increase in the identification of lymphadenopathy (LAD) associated with vaccination. Because axillary lymphadenopathy is a concerning sign of metastatic disease in breast cancer, identifying the difference between benign inflammatory reaction and concerning LAD, and avoiding unnecessary additional imaging and biopsy is an essential skill. This article describes the current literature, recommendations for follow up and interventions to improve diagnostics.

Cardiovascular Complications of Pregnancy-Associated COVID-19 Infections.

Cardiovascular complications are frequently present in coronavirus-2019 (COVID-19) infection. These include microvascular and macrovascular thrombotic complications such as arterial and venous thromboembolism, myocardial injury or inflammation resulting in infarction, heart failure, and arrhythmias. Data suggest increased risk of adverse outcomes in pregnant compared with nonpregnant women of reproductive age with COVID-19 infection, including need for intensive care unit admission, mechanical ventilation, and extracorporeal membrane oxygenation utilization. Current statements addressing COVID-19-associated cardiac complications do not include pregnancy complications that may mimic COVID-19 complications such as peripartum cardiomyopathy, spontaneous coronary artery dissection, and preeclampsia. Unique to pregnancy, COVID-19 complications can result in preterm delivery and modify management of the pregnancy. Moreover, pregnancy has often been an exclusion criterion for enrollment in research studies. In this review, we summarize what is known about pregnancy-associated COVID-19 cardiovascular complications.

Multiple Etiologies to Myocardial Injury in COVID-19.

In patients with acute myocardial injury secondary to coronavirus disease-2019 (COVID-19), cardiovascular magnetic resonance imaging can identify the underlying pathology. We highlight a case of acute myocardial injury secondary to COVID-19, which demonstrated both epicardial vessel thrombosis and the recently described phenomenon of microvascular thrombosis.

Fetal Surgery in the Era of SARS-CoV-2 Pandemic: A Single-Institution Review.

OBJECTIVE: To cope with the changing health care services in the era of SARS-CoV-2 pandemic. We share the institutional framework for the management of anomalous fetuses requiring fetal intervention at Mayo Clinic, Rochester, Minnesota. To assess the success of our program during this time, we compare intraoperative outcomes of fetal interventions performed during the pandemic with the previous year. PATIENTS: We implemented our testing protocol on patients undergoing fetal intervention at our institution between March 1, and May 15, 2020, and we compared it with same period a year before. A total of 17 pregnant patients with anomalous fetuses who met criteria for fetal intervention were included: 8 from 2019 and 9 from 2020. METHODS: Our testing protocol was designed based on our institutional perinatal guidelines, surgical requirements from the infection prevention and control (IPAC) committee, and input from our fetal surgery team, with focus on urgency of procedure and maternal SARS-CoV-2 screening status. We compared the indications, types of procedures, maternal age, gestational age at procedure, type of anesthesia used, and duration of procedure for cases performed at our institution between March 1, 2020, and May 15, 2020, and for the same period in 2019. RESULTS: There were no statistically significant differences among the number of cases, indications, types of procedures, maternal age, gestational age, types of anesthesia, and duration of procedures (P values were all >.05) between the pre-SARS-CoV-2 pandemic in 2019 and the SARS-CoV-2 pandemic in 2020. CONCLUSIONS: Adoption of new institutional protocols during SARS-CoV-2 pandemic, with appropriate screening and case selection, allows provision of necessary fetal intervention with maximal benefit to mother, fetus, and health care provider.

Acute Multivessel Coronary Occlusion Revealing COVID-19 in a Young Adult.

A 42-year-old man was admitted for an ST-segment elevation myocardial infarction revealing an acute thrombosis of the left anterior descending and right coronary arteries. Following this acute multivessel coronary occlusion in a young individual at low cardiovascular risk, he tested positive for severe acute respiratory syndrome-coronavirus-2 infection.

4 Cases of Aortic Thrombosis in Patients With COVID-19.

Since the outbreak of the COVID-19 pandemic, increasing evidence suggests that infected patients present a high incidence of thrombotic complications. This report describes 4 cases of aortic thrombosis in patients admitted for COVID-19 infection between March 26 and April 12, 2020, in Mulhouse, France. (Level of Difficulty: Intermediate.).

Severe COVID-19 After Recent Heart Transplantation Complicated by Allograft Dysfunction.

A 50-year-old male presented with atrial flutter 25 days after heart and kidney transplantation. Rejection was excluded, but he developed severe COVID-19 infection with cardiac allograft dysfunction. Despite continued corticosteroid and tacrolimus therapy, he remained aviremic. Respiratory and myocardial functions recovered after a week of mechanical ventilation. The cardiomyopathy was stress induced. (Level of Difficulty: Advanced.).

Sinus Node Dysfunction in a Young Patient With COVID-19.

A 34-year-old man was admitted with acute lung injury and COVID-19 pneumonia. In the intensive care unit, he experienced episodes of prolonged asystole accompanied by hypotension without loss of consciousness. Once reversible causes were excluded, symptoms were related to dysfunction of the sinus node, and the patient underwent implantation of a pacemaker. (Level of Difficulty: Beginner.).
