To understand the potential causes of laboratory-acquired infections and to provide possible solutions that would protect laboratory personnel, samples from a viral laboratory were screened to determine the main sources of contamination with six subtypes of Rhinovirus. Rhinovirus contamination was found in the gloves, cuffs of protective wear, inner surface of biological safety cabinet (BSC) windows, and trash handles. Remarkably, high contamination was found on the inner walls of the centrifuge and the inner surface of centrifuge tube casing in the rotor...

OBJECTIVE: To evaluate the diagnostic accuracy of three-dimensional (3D) enhanced T1 high-resolution isotropic volume excitation (eTHRIVE) shoulder MR for the detection of rotator cuff tears, labral lesions and calcific tendonitis of the rotator cuff in comparison with two-dimensional (2D) fast spin echo T2 fat saturation (FS) MR. METHODS: This retrospective study included 73 patients who underwent shoulder MRI using the eTHRIVE technique. Shoulder MR images were interpreted separately by two radiologists...

The Laryngeal Mask Airway (LMA) is an accepted adjunct for airway management in emergency patients. There are a number of case reports describing its use in transport medicine for infant to adult patients, including during flight. Although studies of the effect altitude has on air-filled tracheal tubes exists, we were unable to find documentation of the effect of altitude on laryngeal mask airways. Our objective was to assess the effect of altitude on the LMA in both fixed wing and rotary wing models. We performed an in vitro study of the effect of altitude on the LMA cuff...

Reconstructive surgery of rotator cuff tears tries to restore a stable center of rotation in the shoulder joint. Both the classic technique of open surgery and the arthroscopic technique are employed to reconstruct the rotator cuff. This review tries to answer the question which of both surgical techniques is superior by a review of the literature. The recent literature demonstrates a shorter follow-up period for publications concerning arthroscopic reconstruction (mean 3 years) in comparison to open surgery, where follow-up is in mean 6...

Over the last years treatment of rotator cuff tears is evolving gradually from open to complete arthroscopic repair. There had been fast developments in arthroscopic techniques and instruments and there is a better understanding of biomechanical backgrounds. For a good clinical outcome it is not necessary to obtain a watertight closure in all cases but to balance the force couples in the coronal and transverse plane. There is recent discussion regarding the optimum techniques and stitches for cuff reconstruction and resulting developments in this field...

Dynamic aortic valve, a novel design for left ventricular assistance is proposed. An impeller similar to the airscrew is placed in the position of aortic valve. The impeller is held by a pair of bearings in the center of a cylindrical supporting cage which is located in the lumen of the aorta ascendens. The supporting cage is attached to the valve annulus by a sewing ring of textile cuff around the outside of the cage. A rotor is fitted into the cage and connected to the impeller with a common shaft. The cage supports the aortic wall, thus prevents the rotor from founching the wall and allows the rotor to rotate freely...
