Abstract

Coronavirus disease 2019 (COVID-19) has affected medical practice. More than 7,000,000 patients died worldwide after being infected with COVID-19; however, no specific laboratory markers have yet been established to predict death related to this disease. In contrast, electrocardiographic changes due to COVID-19 include QT prolongation and ST-T changes; however, there have not been studies on the ambulatory electrocardiographic markers of COVID-19. We encountered three patients diagnosed as having COVID-19 who did not have a prior history of significant structural heart diseases. All patients had abnormalities in ambulatory echocardiogram parameters detected by high-resolution 24 h electrocardiogram monitoring: positive late potentials (LPs) and T-wave alternans (TWA), abnormal heart rate variability (HRV), and heart rate turbulence (HRT). Case 1 involved a 78-year-old woman with a history of chronic kidney disease, Case 2 involved a 76-year-old man with hypertension and diabetes, and Case 3 involved a 67-year-old man with renal cancer, lung cancer, and diabetes. None of them had a prior history of significant structural heart disease. Although no significant consistent increases in clinical markers were observed, all three patients died, mainly because of respiratory failure with mild heart failure. The LP, TWA, HRV, and HRT were positive in all three cases with no significant structural cardiac disease at the initial phase of admission. The further accumulation of data regarding ambulatory electrocardiographic markers in patients with COVID-19 is needed. Depending on the accumulation of data, the LP, TWA, HRV, and HRT could be identified as potential risk factors for COVID-19 pneumonia in the early phase of admission. [ABSTRACT FROM AUTHOR]

Abstract

Purpose: This study aimed to determine whether severe acidemia (pH <7.2) on arrival at the emergency department (ED) is a predictive factor for neurologic outcomes of post-cardiac arrest patients treated with targeted temperature management (TTM).Materials and Methods: Data in the National Disaster Medical Center, a tertiary care hospital, were used to perform a case-control study on post-cardiac arrest patients treated with TTM from January 2013 to April 2015. The case group comprised patients with good neurologic outcomes (cerebral performance categories 1 and 2), whereas the control group comprised patients with poor neurologic outcomes (cerebral performance categories 3-5). Exposure was defined as arterial pH less than 7.2 on arrival at the ED.Results: We identified 32 patients matching our criteria, of which 13 had good outcomes and 19 poor outcomes. Arterial pH on arrival was not significantly associated with neurologic outcomes (P = .47; odds ratio, 0.5; 95% confidence interval, 0.09-2.61). In 24 patients with cardiogenic causes of cardiac arrest, pH on arrival was not significantly associated with neurologic outcomes (P = .68; odds ratio, 0.5; 95% confidence interval, 0.09-2.73) after matched-pair analysis by age, sex, and presence of light reflex.Conclusion: Severe acidemia on arrival at the ED is not a significant predictive factor for neurologic outcomes in post-cardiac arrest patients treated with TTM, particularly in patients with cardiogenic causes of cardiac arrest. These results suggest that treatment should not be withheld in post-cardiac arrest patients with severe acidemia. [ABSTRACT FROM AUTHOR]

Abstract

Patients with hemophilia A develop severe coagulopathy after major trauma; however, there is no published evidence based on pathophysiology (disseminated intravascular coagulation [DIC] and acute coagulopathy of trauma shock). [ABSTRACT FROM AUTHOR]

Abstract

Invasive pneumococcal disease (IPD) has a high mortality. Although preventive strategies including vaccination have been established for children, less attention has been devoted to pregnant and postnatal women and to mothers caring for their infants. As a significant number of women have either undergone splenectomy or are in a hyposplenic state and have not received adequate pneumococcal vaccinations, they can potentially develop overwhelming postsplenectomy infections. A 34-year-old woman with an 8-month-old baby, who underwent splenectomy at the age of 10 for benign pancreatic tumor, presented with fever and petechial eruption. Despite extensive treatment, she died 17 h after admission. A 40-year-old woman with a 11-month-old baby, who underwent splenectomy at 2 years of age for hemolytic anemia, was admitted for septic shock and disseminated intravascular coagulation. Despite extensive treatment, she died 2 h after admission. Blood cultures from both women were positive for Streptococcus pneumoniae and neither of them had been vaccinated against the bacterium. IPD rapidly progressed and developed to multiple organ dysfunction syndromes in mothers caring for their infants, particularly those who had undergone splenectomy or were in a hyposplenic state. Thus, routine pneumococcal vaccination is recommended for pregnant women. In addition, we suggest a thorough medical interview and checkup for splenectomy or hyposplenism in prenatal women.

Abstract

A 51-year-old man was brought to the emergency room because of a sudden onset of severe dysponea. On presentation, his blood pressure was 94/55 mm Hg. Oxygen saturation was 86% while he was receiving 10 l/min oxygen through a non-rebreather mask. On physical examination, no jugular venous distention was noted, but breath sounds over the left lung were diminished. A bedside chest radiograph showed left tension pneumothorax, for which urgent needle decompression followed by chest thoracostomy was performed. Ventricular tachycardia developed, but a biphasic shock at 120 J immediately restored normal sinus rhythm. His vital signs, however, did not improve. A CT scan of the chest showed type A aortic dissection with bullae in the upper lobe of the left lung. He had an emergency operation for distal aortic arch displacement and was discharged on the 37th day of hospitalisation. [ABSTRACT FROM AUTHOR]
