Surgery biopsy was used to examine 133 patients admitted to hospital for suspected tuberculous spondylitis. The surgical biopsy diagnostic techniques involved biopsy of peripheral lymph nodes, paracentesis of abscesses, puncture and trephine biopsies of vertebral bodies, and open diagnostic vertebrotomy. Biopsy studies using surgical techniques verified the diagnoses of tuberculous spondylitis, vertebral tumors, and nonspecific vertebral osteomyelitis in 115, 8, and 10 patients, respectively. The patients' examination took 2 to 6 weeks. The use of surgical techniques for obtaining biopsy specimens could avoid diagnostic errors and reduce the time of a diagnostic examination.

Aortic lumen repair with glue-felt technique before proximal anastomosis in acute type a aortic dissection surgery.
J Cardiothorac Surg
January 2025
Cerrahpasa Medical Faculty, Department of Cardiovascular Surgery, Istanbul University-Cerrahpasa, Istanbul, Turkey.
Objectives: Despite the advances in medicine, aortic dissection remains a cardiac surgery emergency with high mortality and morbidity rates. This study examined the effects of the Glue + Felt technique, which uses biological glue and felt to repair the proximal anastomotic site, on the outcomes of patients with acute type A aortic dissection.
Methods: A total of 108 patients who underwent surgery for acute type A aortic dissection at our clinic between 2007 and 2020 were included in the study.
Airway pressures generated by high flow nasal cannula in patients with acute hypoxemic respiratory failure: a computational study.

Introduction And Objectives: High flow nasal cannula (HFNC) therapy is an increasingly popular mode of non-invasive respiratory support for the treatment of patients with acute hypoxemic respiratory failure (AHRF). Previous experimental studies in healthy subjects have established that HFNC generates flow-dependent positive airway pressures, but no data is available on the levels of mean airway pressure (mP) or positive end-expiratory pressure (PEEP) generated by HFNC therapy in AHRF patients. We aimed to estimate the airway pressures generated by HFNC at different flow rates in patients with AHRF, whose functional lung volume may be significantly reduced compared to healthy subjects due to alveolar consolidation and/or collapse.

Background: Prophylactic parenteral administration of antibiotics is strongly recommended to prevent surgical site infection (SSI). Cefoxitin is mainly administered intravenously in colorectal surgery. The current standard method for administering prophylactic antibiotics in adults is to administer a fixed dose quickly before skin incision.
