Echocardiographic myocardial dysfunction is reported commonly in sepsis and septic shock, but there are limited data on sepsis-related right ventricular dysfunction. This study sought to evaluate the association of right ventricular dysfunction with clinical outcomes in patients with severe sepsis and septic shock. Historical cohort study of adult patients admitted to all intensive care units at the Mayo Clinic from January 1, 2007 through December 31, 2014 for severe sepsis and septic shock, who had an echocardiogram performed within 72 h of admission. Patients with prior heart failure, cor-pulmonale, pulmonary hypertension and valvular disease were excluded. Right ventricular dysfunction was defined by the American Society of Echocardiography criteria. Outcomes included 1-year survival, in-hospital mortality and length of stay. Right ventricular dysfunction was present in 214 (55%) of 388 patients who met the inclusion criteria—isolated right ventricular dysfunction was seen in 100 (47%) and combined right and left ventricular dysfunction in 114 (53%). The baseline characteristics were similar between cohorts except for the higher mechanical ventilation use in patients with isolated right ventricular dysfunction. Echocardiographic findings demonstrated lower right ventricular and tricuspid valve velocities in patients with right ventricular dysfunction and lower left ventricular ejection fraction and increased mitral E/e′ ratios in patients with combined right and left ventricular dysfunction. After adjustment for age, comorbidity, illness severity, septic shock and use of mechanical ventilation, isolated right ventricular dysfunction was independently associated with worse 1-year survival—hazard ratio 1.6 [95% confidence interval 1.2–2.1; p = 0.002) in patients with sepsis and septic shock. Isolated right ventricular dysfunction is seen commonly in sepsis and septic shock and is associated with worse long-term survival.

COVID-19 disease can lead to multiple complications such as severe acute respiratory distress syndrome (ARDS), coagulopathy, renal failure, cardiac and neurological complications. We describe a case of a patient who developed pneumothorax and pneumomediastinum in the setting of COVID-19 without having ARDS or requiring mechanical ventilation. Our patient developed sudden onset of shortness of breath and desaturation. Chest X-ray and CT chest revealed pneumothorax and pneumomediastinum. Though pneumothorax in pulmonary infection is most likely associated with increased airway pressure in acute respiratory distress syndrome and positive pressure mechanical ventilation. Pneumothorax is a life-threatening complication and if diagnosed early it can reduce mortality. In patients with COVID-19 infection, sudden clinical worsening with shortness of breath and desaturation should prompt the clinician to look for potentially treatable causes such as pneumothorax.

Acute myeloid leukemia (AML) is the most common malignancy in the acute leukemia category. AML is a very aggressive cancer with high mortality. The most common presentations include pancytopenia, bleeding, and recurrent infections. Unlike lymphoma, it rarely presents as a mass. Myeloid sarcoma is a peripheral collection of myeloid cells. Myeloid sarcoma most commonly involves the skin and gingival tissue and rarely it affects the central nervous system. Myeloid sarcoma involving the central nervous system is associated with high mortality. We present a patient with AML which evolved from myelofibrosis presented with acute spinal cord compression and found to have myeloid sarcoma involving the thoracic spinal cord. Despite acute radiation therapy, the patient could not recover her neurological function and passed away shortly after the diagnosis. We discuss the importance of early recognition of the complication due to myeloid sarcoma and treatment with neurosurgical intervention just like other mass causing acute cord compression.
