Schwannoma located in the palate: clinical case and literature review
Schwannoma is a benign tumor that originates from the presence of Schwann cells of the peripheral nerves. They are usually asymptomatic, do not recur, and malignant transformation is rare.The preoperative diagnosis is often difficult, and although computed tomography and magnetic resonance imaging are very helpful, in the majority of cases, the diagnosis can only be made during surgery and by histological study. The immunohistochemistry reveals that the Schwannoma cells test positive for S-100 protein.We describe a clinical case of Schwannoma located in the palate of a 15-year-old patient. It is important to highlight that the Schwannoma is usually found in the head and neck, and rarely in the oral cavity. When it does occur in this area, it is more likely to be found in the tongue. Other locations in the oral cavity include: the floor of the mouth, palate, gingiva, vestibular mucosa, lips and mental nerve area, listed from most common to least common.There has been no sign of recurrence two years after surgery
Surgical ciliated cyst of the maxilla. Clinical case
Surgical ciliated cyst is uncommon in Western countries but frequently reported in Asian populations as a delayed complication of surgery, with inclusion in the bone of nasal or sinus mucosa. Isolated cases have also been reported in the mandible after orthognathic surgery. We report a case in the maxillary region three years after radical sinus surgery for chronic sinusitis. Intraoral examination revealed a small painless tumefaction with no color change in the surrounding tissues. Computed tomography demonstrated a well-defined intraosseous lesion lateral to the maxillary sinus. The lesion was completely excised, when histology demonstrated a pseudostratified ciliated epithelial lining. Differential diagnosis from other lesions such as an odontogenic keratocyst or inflammatory cyst were also made. This case report,uncommon in Western countries, of a surgical ciliated cyst illustrates the need for a meticulous surgical technique, proper management of complications, and routine, long-term follow-up of patients undergoing any type of sinus surgery
Adaptación a la docencia online de las prácticas preclínicas de Cirugía Bucal I
Los cambios en la docencia debido a la pandemia por la COVID-19 ha llevado a la reducción de la presencialidad y a un aumento de la docencia online. Por ello se diseñó este proyecto, cuya finalidad fue la adaptación a la docencia online de las prácticas preclínicas de Cirugía Bucal I.
Para el desarrollo de este trabajo se realizaron las rúbricas de evaluación de cada módulo de la asignatura, se elaboraron videos y documentación para subir al campus virtual antes de la realización de la práctica. Finalmente, se elaboraron cuestionarios de evaluación de la satisfacción de los estudiantes y profesorado con esta metodología. Los resultados mostraron una elevada satisfacción de ambos grupos, considerándola una herramienta de utilidad en el aprendizaje y de implementación en cursos posteriores
Attitude and Knowledge tips in oral surgery
Se han elaborado unas recomendaciones o Tips para el procedimiento de exodoncia, tratamiento más habitual dentro de las prácticas de Cirugía Bucal. Posteriormente, se han publicado para que los estudiantes de tercer, cuarto y quinto curso de Odontología pudieran conocerlas y ofrecer su opinión a través de una encuesta de valoración.
Los resultados han sido muy positivos, considerando los estudiantes que el tríptico de presentación de los Tips, es una herramienta de gran utilidad facilitando su aprendizaje, la adquisición de buenos hábitos profesionales, la evaluación y detección de errores en el procedimiento, así como considerándolos como guía o protocolo de actuación. Obteniendo una satisfacción global muy elevada.Depto. de Especialidades Clínicas OdontológicasFac. de OdontologíaFALSEsubmitte
Guía para la solución de errores frecuentes en la docencia práctica de cirugía bucal
La Cirugía Bucal es una disciplina que se imparte en el Grado de Odontología, en tercer y cuarto curso. Sirve como base y aporta conocimientos previos para cursar otras asignaturas optativas de quinto curso, como la Cirugía Maxilofacial y la Implantología.
Asi mismo, es la asignatura donde se imparten los contenidos de Anestesia Local, prodecimiento imprescindible para realizar cualquier procedimiento terapéutico en los tratamientos odontológicos.
En el desarrollo de la misma, la ejecución práctica de los conocimientos se pone en marcha en cuarto curso. A lo largo de los años, los profesores implicados en la docencia práctica de la asignatura, hemos observado una serie de errores que se repiten en todas las promociones.
Para ayudar al estudiante a prevenir estos errores, se va a elaborar una guía de errores comunes, que se puede actualizar cada curso académico, que le permita conocerlos antes de enfrentarse a la práctica clínica
Evolution over Time of Ventilatory Management and Outcome of Patients with Neurologic Disease∗
OBJECTIVES: To describe the changes in ventilator management over time in patients with neurologic disease at ICU admission and to estimate factors associated with 28-day hospital mortality. DESIGN: Secondary analysis of three prospective, observational, multicenter studies. SETTING: Cohort studies conducted in 2004, 2010, and 2016. PATIENTS: Adult patients who received mechanical ventilation for more than 12 hours. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Among the 20,929 patients enrolled, we included 4,152 (20%) mechanically ventilated patients due to different neurologic diseases. Hemorrhagic stroke and brain trauma were the most common pathologies associated with the need for mechanical ventilation. Although volume-cycled ventilation remained the preferred ventilation mode, there was a significant (p < 0.001) increment in the use of pressure support ventilation. The proportion of patients receiving a protective lung ventilation strategy was increased over time: 47% in 2004, 63% in 2010, and 65% in 2016 (p < 0.001), as well as the duration of protective ventilation strategies: 406 days per 1,000 mechanical ventilation days in 2004, 523 days per 1,000 mechanical ventilation days in 2010, and 585 days per 1,000 mechanical ventilation days in 2016 (p < 0.001). There were no differences in the length of stay in the ICU, mortality in the ICU, and mortality in hospital from 2004 to 2016. Independent risk factors for 28-day mortality were age greater than 75 years, Simplified Acute Physiology Score II greater than 50, the occurrence of organ dysfunction within first 48 hours after brain injury, and specific neurologic diseases such as hemorrhagic stroke, ischemic stroke, and brain trauma. CONCLUSIONS: More lung-protective ventilatory strategies have been implemented over years in neurologic patients with no effect on pulmonary complications or on survival. We found several prognostic factors on mortality such as advanced age, the severity of the disease, organ dysfunctions, and the etiology of neurologic disease
