Vascular Thrombosis in Severe COVID-19 Requiring Extracorporeal Membrane Oxygenation: A Multicenter Study.

Objectives: Coronavirus disease 2019 has been reported to be a prothrombotic condition; however, multicenter data comparing this with other viral pneumonias in those requiring extracorporeal membrane oxygenation are lacking. We conducted a multicenter study using whole-body CT to examine the prevalence, severity, and nature of vascular complications in coronavirus disease 2019 in comparison with patients with other viral pneumonias.

Design: We analyzed whole-body CT scans for the presence of vascular thrombosis (defined as pulmonary artery thrombus, venous thrombus, systemic arterial thrombus, or end-organ infarct).

Cytomegalovirus disease in patients with common variable immunodeficiency: three case reports.

Common variable immunodeficiency (CVID) is the most frequent clinically relevant primary immunodeficiency and shows enormous heterogeneity in clinical presentation. Despite clinical immunodeficiency, opportunistic infections are not a typical manifestation of CVID. A retrospective study of 32 patients followed up for 335 patient-years was performed to determine the frequency of cytomegalovirus (CMV) disease.

Recombinant activated factor VII administration after pulmonary embolectomy: case report.

Bleeding management in cardiac surgery could be a great challenge for the surgeon and a life-threatening moment for the patient. Despite the fact that recombinant activated factor VII is now widely accepted as a useful adjunct in the management of postcardiotomy coagulopathy, its use in the course of recent thromboembolic event is rarely described. We hereby present a case of rescue recombinant activated factor VII administration to manage a severe coagulation disorder during surgical pulmonary embolectomy performed under cardiopulmonary bypass.

Use of bio-degradable stents for the treatment of refractory benign gastrointestinal stenoses.

Bio-degradable stents are be made of different synthetic polymers (like polylactide or polyglycolide) or their co-polymers (polydioxanone). They can be used for treating benign stenoses of the small and large intestine, particularly in Crohn's disease. Endoscopic introduction of bio-degradable stents into small and large intestinal stenoses is feasible and relatively simple.

Reconstruction of an orbital floor fracture in a 4-year-old child.

The authors present a case of a 4-year-old girl with an orbital floor fracture. During surgery absorbable collagenous mesh (Pelvicol) was placed between the bone wall and the orbital periosteum. Pelvicol was selected as a natural xenogeneic tissue (porcine dermis) ready for first use in the reconstruction of the orbital floor fracture.
