COVID-19 has become a pandemic in the United States and worldwide. COVID-19-induced coagulopathy (CIC) is commonly encountered at presentation manifested by considerable elevation of D-dimer and fibrin split products but with modest or no change in activated partial thromboplastin time and prothrombin time. CIC is a complex process that is distinctly different from conventional sepsis-induced coagulopathy. The cytokine storm induced by COVID-19 infection appears to be more severe in COVID-19, resulting in development of extensive micro- and macrovascular thrombosis and organ failure. Unlike conventional sepsis, anticoagulation plays a key role in the treatment of COVID-19, however without practice guidelines tailored to these patients. We propose a scoring system for COVID-19-coagulopathy (CIC Scoring) and stratification of patients for the purpose of anticoagulation therapy based on risk categories. The proposed scoring system and therapeutic guidelines are likely to undergo revisions in the future as new data become available in this evolving field.

Intussusception is a rare phenomenon in adults and usually presents with bowel obstruction. Unlike child intussusception, adult intussusception is seldom idiopathic and frequently associated with secondary causes such as benign and malignant tumors. While most cases are treated surgically, emerging data suggest a more conservative management approach for patients with short-segment adult intussusception and without high-risk features such as bowel obstruction, mass seen on imaging, colon involvement, or constitutional symptoms of malignancy. We present a rare case of adult intussusception due to unsuspected adenocarcinoma of the jejunum, treated successfully with surgical resection followed by adjuvant chemotherapy. We favor the surgical rather than conservative approach for adult patients with intussusception to avoid missing unsuspected malignant tumors that are not readily visualized on imaging studies.

Primary cardiac lymphoma (PCL) is a rare neoplasm that involves the heart, pericardium, or both. Patients with PCL have median survival of approximately 7 months. We report a 63-year-old woman with PCL treated with chemoimmunotherapy but relapsed 7 years later. She received automated implantable cardioverter-defibrillator (AICD) prophylactically shortly after the diagnosis. She presented with a breast recidive 7 years after initial diagnosis and died of relapsed small cell lung cancer. As many patients with PCL die early in the disease course due to life-threatening arrhythmias, preemptive implantation of AICD may improve mortality and prevent early death. Chemoimmunotherapy is effective in inducing remission in patients with PCL. Late and unusual pattern of relapse may be more frequent in patients with PCL and should be explored further. This case presents one of the longest surviving patients with PCL reported in the literature.
