Patients with coronavirus disease 19 (COVID-19) have increased susceptibility to secondary respiratory infections including invasive pulmonary aspergillosis (IPA). COVID-19-associated pulmonary aspergillosis (CAPA) is difficult to diagnose and can be associated with increased mortality especially in severe immunodeficiency such as hematological malignancies. Our study evaluates IPA in COVID-19 patients defined as COVID-19-CAPA among patients with acute leukemia (AL). A retrospective single-center study analyzed 46 patients with COVID-19 infection and acute leukemia, admitted to the Clinic for Haematology, Clinical Center of Serbia, Belgrade between the 2 April 2020 and 15 May 2021. During hospitalization, all participants were diagnosed with probable IPA according to the previous consensus definitions. Positive serology and galactomannan (GM) detection values in bronchoalveolar lavage (BAL) and serum were used as microbiological criteria. COVID-19 associated probable IPA was found in 22% (9/41) tested patients, where serum GM and IgM anti-Aspergillus antibodies were positive in 12% (5/41) and 10% (4/41) had positive serology for aspergillosis. One patient died while eight recovered during follow-up. Our study showed that COVID-19 might be a risk factor for IPA development in patients with AL. Early diagnosis and prompt treatment are required as reported mortality rates are high.

Patients with acute leukemia (AL) have a high mortality rate from coronavirus disease 2019 (COVID-19). However, studies including patients with AL and COVID-19 are few. Fifty-one patients with AL and COVID-19 were included in our study. The mortality rate was 17/51 (29.4%). In all cases, death was associated with COVID-19 pneumonia. The major driver of outcome was the disease status (worse outcome was observed in newly diagnosed (OR, 6.00; 95% CI, 1.133 - 15.188) and patients with bone marrow aplasia (OR 4.148 [95% CI 1.133 - 15.188])). Higher mortality rate was associated with lower platelet count, prolonged PT, higher ISTH DIC score, CRP and LDH. Moreover, careful risk-benefit assessment regarding the continuation of anticancer therapy is required in patients receiving nonintensive and supportive therapy. Considering the high frequency of intrahospital viral transmission (50.98%), isolation of AL patients in single rooms, and permanent symptom monitoring and testing should be prioritized.

Giant or Himalayan P waves are tall and peaked, the most prominent in lead II, and generally indicate enlargement of the right atrium. It has been rarely seen in clinical practice. The mechanism of Himalayan P wave formation is most likely related with prolonged conduction of electrical impulses through the enlarged right atrium. We describe the case of a patient with Himalayan P wave admitted for cardiac surgery.

Introduction. Intramural hematoma of the aorta presents potentially fatal condition developing as a result of a vasa vasorum rupture. It is a major risk factor for developing a frank aortic dissection. Case Outline. A 65-year-old woman was admitted to our clinic for the second time, after her symptoms of chest pain and vertigo (with no electrocardiographic signs of myocardial infarction) hadn?t disappeared after several months of medicament treatment (indicated in the first hospitalization). Computed tomography arteriography of the aorta showed no sign of acute aortic dissection, but revealed a contrast depo in the aortic wall of 8 ? 14 mm dimensions, with no extravasation of contrast. Also, massive pericardial effusion was observed (10-30 mm in thickness). Transesophageal echocardiography confirmed these findings completely. The patient underwent surgery, in which plaque exulceration was detected on the convex side of the ascending aorta, 3 cm above the aortic valve, 1 cm in diameter, with no signs of intimal tear. A resection of the ascending aorta was performed, and the aorta was reconstructed with a 30 mm Dacron tube graft. The patient was discharged on the 14th postoperative day with satisfactory results. Conclusion. Intramural hematoma is not a common event, but it is potentially a fatal one. Open surgery in patients with an intramural hematoma is an effective treatment strategy, although percutaneous endovascular treatment options are being described.
