A Rare Cause of Isolated Prolonged Activated Partial Thromboplastin Time: An Overview of Prekallikrein Deficiency and the Contact System.
Prekallikrein (PK) deficiency, also known as Fletcher factor deficiency, is a very rare disorder inherited as an autosomal recessive trait. It is usually identified incidentally in asymptomatic patients with a prolonged activated partial thromboplastin time (aPTT). In this article, we present the case of a 52-year-old woman, with no prior personal or family history of thrombotic or hemorrhagic disorders, who was noted to have substantial protracted aPTT through the routine coagulation assessment before a kidney biopsy. ⋯ Thus, other differential diagnoses of isolated prolonged aPTT include intrinsic pathway factor deficiencies and nonspecific inhibitors such as LA. We concluded that the initial evaluation of a prolonged aPTT with normal PT should appraise the measurement of contact activation factors and factor inhibitors. PK deficiency should be considered in asymptomatic patients with isolated aPTT prolongation, which corrects on incubation, with normal levels of the contact activation factors and factor inhibitors.

Case ReportsAtrial Arrhythmias in a Patient Presenting With Coronavirus Disease-2019 (COVID-19) Infection.
The coronavirus disease-2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) that has significant potential cardiovascular implications for patients. These include myocarditis, acute coronary syndromes, cardiac arrhythmias, cardiomyopathies with heart failure and cardiogenic shock, and venous thromboembolic events. We describe a Caribbean-Black gentleman with COVID-19 infection presenting with atrial arrhythmias, namely, atrial flutter and atrial fibrillation, which resolved with rate and rhythm control strategies, and supportive care.

Review Case ReportsA Case Series of Patients Coinfected With Influenza and COVID-19.
Coronavirus disease 2019, also called COVID-19, is a global pandemic resulting in significant morbidity and mortality worldwide. In the United States, influenza infection occurs mainly during winter and several factors influence the burden of the disease, including circulating virus characteristics, vaccine effectiveness that season, and the duration of the season. We present a case series of 3 patients with coinfection of COVID-19 and influenza, with 2 of them treated successfully and discharged home. We reviewed the literature of patients coinfected with both viruses and discussed the characteristics, as well as treatment options.

Review Case ReportsAcute Eosinophilic Pneumonia Secondary to Menthol Cigarette Use: A Rare Phenomenon With a Review of Literature.
Idiopathic acute eosinophilic pneumonia (AEP) is a very rare disease with fewer than 200 cases reported. It has been hypothesized to be a hypersensitivity reaction to an unidentified antigen. The clinical presentation typically involves fever, nonproductive cough, shortness of breath, and bibasilar inspiratory crackles within the first week of antigen exposure. ⋯ One week later, the patient was completely free of symptoms. The initiation of menthol cigarette use in this patient is the likely reason for ensuing acute eosinophilic pneumonia, hence adding to the sporadic reports on the role of menthol-flavored cigarettes. This case emphasizes a greater reliance on risk factors, as opposed to eosinophilic markers, for the diagnosis and treatment of acute eosinophilic pneumonia to prevent subsequent respiratory failure and intubation in such patients.

Review Case ReportsMonoclonal Gammopathy of Renal Significance-A Rare Renal Presentation: A Review of Cases Reported.
Monoclonal gammopathy of undetermined significance is a precursor to multiple myeloma characterized by monoclonal gammopathy without evidence of end organ damage. Some patients with clonal plasma cell disorder that do not meet the requirements for multiple myeloma have been seen to develop pathologic renal disease due to direct effects from deposition of monoclonal protein, referred to as monoclonal gammopathy of renal significance. In this article, we present a rare renal manifestation of monoclonal gammopathy of renal significance as focal segmental glomerulosclerosis.
