Chromogenic Factor X Assay for Monitoring Warfarin Anticoagulation in a Child With a Prosthetic Mitral Valve
Mechanical mitral valve replacement in infants and young children is associated with substantial morbidity and mortality. Lifelong anticoagulation is required, with all the accompanying challenges of maintaining levels in infants and children whose dietary input continually changes. Even with careful control of all aspects that can perturb the coagulation cascade, these patients have a substantial lifelong risk of thrombotic and hemorrhagic complications that can also affect the durability of the valve.Successful Treatment of Pembrolizumab-Induced Severe Capillary Leak Syndrome and Lymphatic Capillary Dysfunction
Although capillary leak syndrome has a high mortality rate, its trigger, diagnosis, and treatment remain a challenge to clinicians because of the poor understanding of its mechanism and lack of treatment guidelines. With the extended use of immune checkpoint inhibitors in modern oncology, immune checkpoint inhibitor–associated immune-related adverse events have also expanded. We present a case of pembrolizumab-induced capillary leak syndrome and lymphatic capillary dysfunction in which the patient had an excellent clinical response to a tailored treatment strategy.Glycemic Outcomes of Second-Line Diabetes Drug Choice in a Real-World Population
Hypoglycemia and acute metabolic complications (AMCs; ketoacidosis, hyperosmolarity, and coma) are glycemic outcomes that have high cost and high morbidity; these outcomes must be taken into consideration when choosing initial second-line therapy after metformin. We conducted a retrospective cohort study analyzing national administrative data from adults with type 2 diabetes mellitus who started a second-line diabetes medication (sulfonylureas [SFUs], thiazolidinediones [TZDs], glucagon-like peptide 1 [GLP-1] agonists, dipeptidyl peptidase 4 [DPP-4] inhibitors, basal insulin, or sodium-glucose contransporter 2 [SGLT-2] inhibitors) between April 1, 2011 and September 30, 2015 (N=43,288) and compared rates of hypoglycemia and AMCs.Management of Hypertriglyceridemia-Induced Acute Pancreatitis in a Nondiabetic Patient
Treatment strategies for hypertriglyceridemia-induced acute pancreatitis are not well defined in the current literature or guidelines. One therapeutic option is an insulin infusion accompanied by a dextrose infusion to avoid hypoglycemia. The purpose of this case report is to highlight dosing considerations for dextrose infusions in nondiabetic patients. We describe a case of hypertriglyceridemia-induced acute pancreatitis in a 34-year-old nondiabetic woman treated with a reduced-dose insulin infusion that was complicated by hypoglycemic episodes requiring dextrose infusion titrations.EVALI: A Mimicker of COVID-19
E-cigarette or vaping product use–associated lung injury (EVALI) is a respiratory illness that has significant overlap with the symptoms of coronavirus disease 2019 (COVID-19). In the current pandemic, diagnosis of EVALI may be delayed because of anchoring bias when patients present with symptoms consistent with COVID-19. We present 3 cases of patients who were hospitalized with a presumed diagnosis of COVID-19 but were later diagnosed with EVALI.
