Experiencia interdisciplinaria para el diseño de productos para la salud

Rev. méd. Chile; 145 (10), 2017
Background: Training of innovative health professionals is necessary for the development of an effective health system in a limited resources context. However, the professionals underestimate their innovative role and receive sparse training in this issue. Meanwhile, industrial designers are trained to i...

Comparison of short-segment monoaxial and polyaxial pedicle screw fixation combined with intermediate screws in traumatic thoracolumbar fractures: a finite element study and clinical radiographic review

Clinics; 72 (10), 2017
OBJECTIVES: No studies have compared monoaxial and polyaxial pedicle screws with regard to the von Mises stress of the instrumentation, intradiscal pressures of the adjacent segment and adjacent segment degeneration. METHODS: Short-segment monoaxial/polyaxial pedicle screw fixation techniques were compa...

Comparison of three different insertion techniques with LMA-UniqueTM in adults: results of a randomized trial

Rev. bras. anestesiol; 67 (5), 2017
Abstract Background The triple airway maneuver insertion technique allowed faster insertion of the LMA. This study compared three different insertion techniques of the laryngeal mask airway-UniqueTM. Methods One hundred and eighty ASA I-II patients aged 18-65 years were included into the study. Patient...

A comparison of three different needles used for spinal anesthesia in terms of squamous epithelial cell transport risk

Rev. bras. anestesiol; 67 (5), 2017
Abstract Background and objectives To investigate the differences in the number of squamous epithelial cells carried to the spinal canal by three different types of spinal needle tip of the same size. Methods Patients were allocated into three groups (Group I, Group II, Group III). Spinal anesthesia wa...

Comparison of different stylets used for intubation with the C-MAC D-Blade® Videolaryngoscope: a randomized controlled study

Rev. bras. anestesiol; 67 (5), 2017
Abstract Objective The angle of the C-MAC D-Blade® videolaryngoscope, which is used for difficult airway interventions, is not compatible with routinely used endotracheal tubes. Methods A prospective randomized crossover study was performed comparing five intubation methods for use with standardized a...

Minimally Invasive Epicardial Pacemaker Implantation in Neonates with Congenital Heart Block

Arq. bras. cardiol; 109 (4), 2017
Abstract Background: Few studies have characterized the surgical outcomes following epicardial pacemaker implantation in neonates with congenital complete atrioventricular block (CCAVB). Objective: This study sought to assess the long-term outcomes of a minimally invasive epicardial approach using a su...

Effect of ultrasound streaming on the disinfection of flattened root canals prepared by rotary and reciprocating systems

J. appl. oral sci; 25 (5), 2017
Abstract New technical and scientific developments have been advocated to promote the success of the endodontic treatment. In addition to rotary and reciprocating systems, irrigating solution agitation has been suggested and passive ultrasonic irrigation (PUI) is the most used. Objective: To evaluate, in...

Metrical analysis of disc-condyle relation with different splint treatment positions in patients with TMJ disc displacement

J. appl. oral sci; 25 (5), 2017
Abstract Objective: To evaluate the effect of bite positions characterizing different splint treatments (anterior repositioning and stabilization splints) on the disc-condyle relation in patients with TMJ disc displacement with reduction (DDwR), using magnetic resonance imaging (MRI). Material and Meth...

Clinics; 72 (9), 2017
OBJECTIVE: To investigate the value of high-flow nasal cannula oxygen therapy after extubation in patients with acute respiratory failure. METHODS: A single-center, prospective, randomized, controlled pilot trial was conducted between January 2013 and December 2014. Sixty enrolled patients were randomiz...

Development and evaluation of an inhalation chamber for in vivo tests

An. acad. bras. ciênc; 89 (3), 2017
ABSTRACT The bioavailability, toxicity, and therapeutic efficacy of a drug is directly related to its administration route. The pulmonary route can be accessed by inhalation after fumigation, vaporization or nebulization. Thus, pharmacological and toxicological evaluation accessed by an apparatus specifi...
