Experiencia de uso de un canal de difusión de contenidos corporativos en un entorno universitario Canal EITE.TV

[ES]En este artículo describimos la experiencia llevada a cabo en la Escuela de Ingeniería de Telecomunicación y Electrónica (EITE) de la Universidad de Las Palmas de Gran Canaria (ULPGC) con la puesta en marcha de un canal de Televisión Corporativa basado en Digital Signage (DS). Explicamos el devenir de la experiencia durante dos cursos académicos (bienio 2012-2014), su implementación técnica, así como el modelo de gestión de contenidos que se ha implantado para permitir un uso eficiente del sistema como herramienta de comunicación para su comunidad de usuarios.

Valoración de los estudiantes de la ULPGC sobre la creación de un canal propio de televisión

[ES]Son muchas las universidades en todo el mundo que han apostado, con mayor o menor éxito, por utilizar las tecnologías digitales de televisión en los diferentes campos de la enseñanza mediante el uso de los portales corporativos de televisión y de Internet. Mediante un estudio piloto realizado con un número reducido de alumnos de la Universidad de Las Palmas de Gran Canaria (ULPGC), este artículo analiza la valoración que hacen los estudiantes sobre la implantación de un canal propio de Televisión Universitario Interactivo con la novedad de ser difundido también por la red de Televisión Digital Terrestre (TDT) ,y así intentar dar a conocer las actividades relacionadas con la vida universitaria a la sociedad a través de un medio masivo de difusión de televisión y con amplia penetración en los hogares.

Air within the spinal canal in spontaneous pneumomediastinum

Spontaneous pneumomediastinum is an uncommon benign condition that is occasionally associated with air within the spinal canal. We describe a further case in a 14-year-old girl and suggest a classification system based on a detailed review of the previous literature. Forty-eight patients with spontaneous pneumomediastinum and intraspinal air accumulation (36 men and 12 women, age range 4-72 years, median age 18 years) were grouped into those with underlying lung disease (n = 13), those with other underlying etiologic factors (n = 22), and those arising spontaneously (n = 13). Neurologic symptoms or signs were noted in one case. The remaining cases were successfully managed conservatively. In spontaneous pneumomediastinum, accumulation of air within the spinal canal is self-limiting and benign. The same management is advised in spontaneous pneumomediastinum with and without intraspinal air accumulation.

Hand and ultrasonic instrumentation for orthograde root canal treatment of permanent teeth

Root canal treatment is a frequently performed dental procedure and is carried out on teeth in which irreversible pulpitis has led to necrosis of the dental pulp. Removal of the necrotic tissue remnants and cleaning and shaping of the root canal are important phases of root canal treatment. Treatment options include the use of hand and rotary instruments and methods using ultrasonic or sonic equipment. OBJECTIVES: The objectives of this systematic review of randomized controlled trials were to determine the relative clinical effectiveness of hand instrumentation versus ultrasonic instrumentation alone or in conjunction with hand instrumentation for orthograde root canal treatment of permanent teeth. MATERIAL AND METHODS: The search strategy retrieved 226 references from the Cochrane Oral Health Group Trials Register (7), the Cochrane Central Register of Controlled Trials (CENTRAL) (12), MEDLINE (192), EMBASE (8) and LILACS (7). No language restriction was applied. The last electronic search was conducted on December 13th, 2007. Screening of eligible studies was conducted in duplicate and independently. RESULTS: Results were to be expressed as fixed-effect or random-effects models using mean differences for continuous outcomes and risk ratios for dichotomous outcomes with 95% confidence intervals. Heterogeneity was to be investigated including both clinical and methodological factors. No eligible randomized controlled trials were identified. CONCLUSIONS: This review illustrates the current lack of published or ongoing randomized controlled trials and the unavailability of high-level evidence based on clinically relevant outcomes referring to the effectiveness of ultrasonic instrumentation used alone or as an adjunct to hand instrumentation for orthograde root canal treatment. In the absence of reliable research-based evidence, clinicians should base their decisions on clinical experience, individual circumstances and in conjunction with patients' preferences where appropriate. Future randomized controlled trials might focus more closely on evaluating the effectiveness of combinations of these interventions with an emphasis on not only clinically relevant, but also patient-centered outcomes.

Morphology of the nasopalatine canal and dental implant surgery: a radiographic analysis of 100 consecutive patients using limited cone-beam computed tomography

To analyze the dimensions and anatomic characteristics of the nasopalatine canal and the corresponding buccal bone plate of the alveolar process, using limited cone-beam computed tomography (CBCT) imaging.

Ear canal cholesteatoma: meta-analysis of clinical characteristics with update on classification, staging and treatment

We present an update on clinical evaluation, staging, classification and treatment of canal cholesteatoma, including a meta-analysis of clinical data of the last 30 years.

In-the-canal versus behind-the-ear microphones improve spatial discrimination on the side of the head in bilateral cochlear implant users

To test whether in-the-canal (ITC) microphones have an impact on spatial discrimination and speech perception by taking advantage of auricular cues.

Feasibility of image-guided radiotherapy based on tomotherapy for the treatment of locally advanced anal carcinoma

The standard of care for locally advanced anal cancer has been concurrent chemoradiation. However, conventional treatment with 3-dimensional radiotherapy is associated with significant toxicity. The feasibility of new radiotherapy techniques such as image-guided radiotherapy (IGRT) in combination with chemotherapy for the treatment of this malignancy was assessed.

Radiographic study of the mandibular retromolar canal: an anatomic structure with clinical importance

The retromolar canal is an anatomic structure of the mandible with clinical importance. This canal branches off from the mandibular canal behind the third molar and travels to the retromolar foramen in the retromolar fossa. The retromolar canal might conduct accessory innervation to the mandibular molars or contain an aberrant buccal nerve.

Irrigants for non-surgical root canal treatment in mature permanent teeth

Root canal treatment is carried out on teeth in which irreversible pulpitis has led to necrosis of the dental pulp. As a treatment option it is an alternative to dental extraction. Mechanical preparation and irrigation with antiseptic or antibacterial solutions destroys bacteria and cleans the infected root canal. Irrigants should be effective in deactivating bacteria in the entire root canal space without causing any adverse tissue reactions. Sodium hypochlorite (NaOCl) and chlorhexidine are commonly used but there is uncertainty as to which solution, concentration or combination is the most effective.
