Radiation dose and image quality of X-ray volume imaging systems: cone-beam computed tomography, digital subtraction angiography and digital fluoroscopy.

Objective: Radiation dose and image quality estimation of three X-ray volume imaging (XVI) systems.

Methods: A total of 126 patients were examined using three XVI systems (groups 1-3) and their data were retrospectively analysed from 2007 to 2012. Each group consisted of 42 patients and each patient was examined using cone-beam computed tomography (CBCT), digital subtraction angiography (DSA) and digital fluoroscopy (DF).

The choice of the intravenous fluid influences the tolerance of acute normovolemic anemia in anesthetized domestic pigs.

Introduction: The correction of hypovolemia with acellular fluids results in acute normovolemic anemia. Whether the choice of the infusion fluid has an impact on the maintenance of oxygen (O₂) supply during acute normovolemic anemia has not been investigated so far.

Methods: Thirty-six anesthetized and mechanically ventilated pigs were hemodiluted to their physiological limit of anemia tolerance, reflected by the individual critical hemoglobin concentration (Hbcrit).

Emergency airway management in trauma patients using laryngeal tube suction.

Background: Endotracheal intubation (ETI) is considered to be the "gold standard" of prehospital airway management of trauma patients. However, ETI requires substantial technical skills and ongoing experience. Because failed prehospital ETI is common and associated with a higher mortality, reliable airway devices are needed to be used by rescuers who are less experienced in ETI.

Intracerebral mass bleeding in a term neonate: manifestation of hereditary protein S deficiency with a new mutation in the PROS1 gene.

Background: Vitamin K deficiency is the major cause of coagulopathy-induced intracranial bleeding in term neonates and is considered first in any term neonate with severe hemorrhage. The most common manifestation of hereditary prothrombotic disorders during the neonatal period is thrombosis of the A. cerebri media or sinus thrombosis.

Mitomycin C, 5-fluorouracil and folinic acid (Mi-Fu-Fo) as salvage chemotherapy in breast cancer patients with liver metastases and impaired hepatic function: a phase II study.

Patients with measurable liver metastases due to breast cancer and elevated liver enzymes were enrolled into the study. The planned schedule was mitomycin C 8 mg/m2 on day 1, 5-fluorouracil 750 mg/m2 and folinic acid 300 mg/m2 on day 1 and 2 every 4 weeks (Mi-Fu-Fo). Between May 1998 and December 2002, 30 patients with a median age of 51 years (range 33-74) were enrolled.
