[Feasibility of cardiac surgical techniques for intrathoracic tumors].

Objective: To analyse safety and expediency of cardiac surgical technologies including cardiopulmonary bypass (CPB) in patients with locally advanced lung cancer and invasive tumors of the mediastinum.

Material And Methods: Cardiac surgical techniques and CPB were used in 23 patients (group 1) with locally advanced thoracic tumors between 2005 and 2015. For the same period, there were 22 patients (group 2) who underwent combined surgeries and could have had similar techniques.

Simultaneous operations for gastric cancer and aortic aneurysm: a case report.

Background: Gastric cancer is the second highest cause of morbidity among malignant tumors of the gastrointestinal tract and fifth in overall cancer statistics. Diseases of the cardiovascular system are the leading causes of death in the world. Aneurysm of the abdominal aorta is the most common type of vascular aneurysm, while in 75% of the cases it is asymptomatic.

Enhanced directional extraction of very cold neutrons using a diamond nanoparticle powder reflector.

For more than a decade, detonation nanodiamond (DND) powders have been actively studied as a material for efficient reflectors of very cold neutrons (VCNs) and cold neutrons. In this work, we experimentally demonstrate, for the first time, the possibility of enhanced directional extraction of a VCN beam using a reflector made of fluorinated DND powder. With respect to the theoretical flux calculated from an isotropic source at the bottom of the reflector cavity, the gain in the VCN flux density along the beam axis is ∼10 for the neutron velocities of ∼57 and ∼75 m/s.

A Coronavirus Disease 2019 (COVID-19) Mystery: Persistent Fevers and Leukocytosis in a Patient With Severe COVID-19.

Short-course glucocorticosteroids are being used and tocilizumab (TCZ) had been used to treat patients with severe coronavirus disease 2019 (COVID-19) disease. These agents, when administered individually, have been associated with tuberculosis (TB) during chronic use. We report a case of TB in a 44-year-old male with diabetes and severe COVID-19 who received high-dose short-course glucocorticosteroids and a single dose of TCZ.

[Resection of recurrent hemangioma of the anterior mediastinum with aortic arch replacement and simultaneous resection of left atrial myxoma].

Patients with anterior mediastinum tumors fall into a difficult category due to high risk of invasion of vital structures and complexity of surgical correction. We report resection of recurrent hemangioma of anterior mediastinum with aortic arch replacement and simultaneous resection of left atrial myxoma in a 35-year-old woman. Successful treatment of these patients correlates with aggressive surgical approach followed by total resection of tumor and all affected vessels and other tissues.

Alcohol and the Hospitalized Patient.

Alcohol use is a common social and recreational activity in our society. Misuse of alcohol can lead to significant medical comorbidities that can affect essentially every organ system and lead to high health care costs and utilization. Heavy alcohol use across the spectrum from binge drinking and intoxication to chronic alcohol use disorder can lead to high morbidity and mortality both in the long and short term.

Morphologically proved ANCA positive Loeffler's pancarditis: medical and surgical treatment.

Loeffler's endocarditis remains is a very rare disease, develops due to eosinophilic inflammation predominantly of the endocardium with an outcome in fibrosis and massive thrombus formation and. He is generally characterized by an unfavorable prognosis. Clinical case of a 42-year-old patient with Loeffler endocarditis is presented.

Relationship between proteinuria and venous thromboembolism.

Nephrotic syndrome is known to cause venous thromboembolism (VTE) due to urine loss of antithrombin III and activation of the coagulation system. We hypothesized that the degree of proteinuria may predict the development of VTE. This was a retrospective case-controlled study of in-patients urban academic teaching hospital from April, 2007 to March, 2009 and who had undergone an imaging study for VTE.
