Given their ease of use, safety, and efficacy, direct-acting oral anticoagulants (DOACs) are nowadays widely used in patients with atrial fibrillation or venous thromboembolism, with or without an association with malignancy. Andexanet alfa (andexanet) is a recombinant modified human factor Xa decoy protein that reverses the inhibition of factor Xa. After Food and Drug Administration (FDA) approval in May 2018, andexanet has been used for life-threatening bleeding in patients treated with apixaban or rivaroxaban. ⋯ A total of four patients in a period of 10 months received andexanet for intracranial bleeding, 50% (2) had excellent hemostasis, 30 days mortality was 75% (3), and 25% (1) had a thromboembolic event. Anticoagulation was never started in all patients. This review tends to show the real-world utilization data of andexanet in a community hospital setting.

Case Reports
Metformin Associated Lactic Acidosis in the Intensive Care Unit: A Rare Condition Mimicking Sepsis.
Metformin-associated lactic acidosis (MALA) is a rare but serious complication of metformin use, associated with high mortality. MALA can occur any time a patient on metformin suffers disruption in renal function resulting in the accumulation of metformin. A 63-year-old man with a history of non-insulin-dependent type 2 diabetes mellitus, alcohol abuse, and hypothyroidism was brought to the emergency department with altered mental status, nausea, vomiting, and abdominal pain. ⋯ Recommendations for the optimal treatment of MALA mostly depend on expert opinion and case reports. Treatment is restricted to supportive measures, although hemodialysis may offer a protective effect. Our case demonstrates that even in extreme cases of MALA, prompt and adequate supportive measures can produce a favorable outcome.

Over the last few months, the coronavirus disease 2019 (COVID-19) pandemic has created overwhelming challenges for physicians across the world. While much has been described in the literature about lung infiltrates and respiratory failure associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), pneumothorax remains a relatively rare presentation with current literature indicating a rate of one percent. We describe a case series of three patients each of whom tested positive for SARS-CoV-2 on reverse-transcriptase polymerase chain reaction testing of nasopharyngeal swab specimens and presented with pneumothorax. ⋯ CT scans in these patients showed bilateral air space disease consistent with COVID-19 pneumonia and pneumothorax with other features including pneumomediastinum, subcutaneous emphysema, and pneumatoceles. This may indicate the underlying pathogenesis of pneumothorax in these patients to involve inflammation-induced pulmonary parenchymal injury and necrosis with subsequent development of air leaks into the pleural cavity, a mechanism similar to that noted in patients during the severe acute respiratory syndrome (SARS) outbreak in 2003. Conservative management with chest tube drainage or observation was adequate for two of three patients while one patient developed multi-organ system dysfunction and eventual death.

Electrical storm (ES) is classified as at least three episodes of ventricular tachycardia (VT) or ventricular fibrillation (VF) in any 24-hour period. Stellate ganglion blockade and left stellate ganglionectomy have shown benefit in terminating ES. A 64-year-old white male with a past medical history of atrial fibrillation, coronary artery disease requiring previous cardiac bypass surgery in 1997, and coronary artery stents in 2003 presented with syncope and refractory ventricular tachycardia/fibrillation. He eventually underwent both an ultrasound-guided left stellate ganglion block and left cardiac sympathetic denervation with left stellate ganglionectomy. In the setting of refractory ES, the left stellate ganglion block followed by left stellate ganglionectomy can be a lifesaving intervention.

Introduction Kawasaki disease (KD) is an idiopathic, acute systemic vasculitis typically affecting medium-sized blood vessels with an inclination towards the coronary arteries. There is no specific diagnostic test established for it yet. Hence, our study aims to evaluate serum N-terminal pro-brain natriuretic peptide (NT-proBNP), hydrogen sulfide (H2S), and interleukin-6 (IL-6) levels as potential diagnostic tools in children with KD and determine its relationship with the development of coronary artery lesions (CAL) in the pediatric population visiting a tertiary care hospital in Karachi. ⋯ However, H2S levels during the acute attack were significantly lower in the CAL group when compared to the NCAL or control groups (p<0.001). Conclusion Elevated levels of NT-proBNP and IL-6 can be utilized as potential clinical markers for identifying children at risk of developing CAL as a complication of KD. Reduced H2S levels are also proposed as an indicator of progress towards CAL and should be considered in reaching a diagnosis.
