Popularidad de Neurología en España: análisis de la elección de la especialidad / The popularity of neurology in Spain: An analysis of specialty selection

INTRODUCCIÓN: Neurología es una de las especialidades ofertadas a los opositores que acceden a la formación sanitaria especializada cada año. Este proyecto analiza los datos de elección de Neurología en los últimos años. MATERIAL Y MÉTODOS: Los datos de la elección se han obtenido de la publicación oficial del Ministerio de Sanidad, Servicios Sociales e Igualdad. Se ha recabado información de los distintos centros docentes con relación a la disponibilidad de unidad de ictus, intervencionismo endovascular, consultas de referencia nacional relacionadas con Neurología, guardias específicas para residentes y vinculación con facultades de medicina o redes de investigación nacional. RESULTADOS: La mediana de elección de número de orden para Neurología ha descendido anualmente, situando la especialidad en la convocatoria 2016 entre las cuatro más populares. Los electores son mayoritariamente mujeres de nacionalidad española y baremo académico alto. La mediana de los hospitales con mayor número de camas, intervencionismo vascular, unidad de ictus o consultas de referencia nacional es significativamente menor. Lo mismo sucede al analizar los centros según guardias específicas de Neurología para residentes o vinculación con facultades de medicina o redes de investigación nacionales. Los centros con menor mediana de número de orden para el periodo 2012-2016 fueron los hospitales universitarios Clínico San Carlos, 12 de Octubre y Vall d'Hebron. CONCLUSIONES: Neurología ha ido mejorando de manera progresiva en la elección de plazas de especialización, situándose entre las cuatro más populares. Los electores se decantan por centros grandes, de mayor complejidad asistencial y con intensa actividad investigadora

INTRODUCTION: Neurology is one of the medical specialties offered each year to residency training candidates. This project analyses the data associated with candidates choosing neurology residency programmes in recent years. METHODS: Data related to specialty selection were obtained from official reports by the Spanish Ministry of Health, Social Services, and Equality. Information was collected on several characteristics of teaching centres: availability of stroke units, endovascular intervention, national reference clinics for neurology, specific on-call shifts for neurology residents, and links with medical schools or national research networks. RESULTS: The median selection list position of candidates selecting neurology training has been higher year on year; neurology was among the 4 most popular residency programmes in 2016. Potential residents were mainly female, Spanish, and had good academic results. The median number of hospitals with higher numbers of beds, endovascular intervention, stroke units, and national reference clinics for neurology is significantly lower. This is also true when centers are analysed by presence of specific on-call shifts for neurology residents and association with medical schools or national research networks. The centres selected by candidates with the highest median selection list position in 2012-2016 were the Clínico San Carlos, 12 de Octubre, and Vall d'Hebron university hospitals. CONCLUSIONS: Neurology has gradually improved in residency selection choices and is now one of the 4 most popular options. Potential residents prefer larger centres which are more demanding in terms of patient care and which perform more research activity

I Conferencia Nacional de Consenso sobre el Injerto Óseo del Seno Maxilar / 1st National Consensus Conference on maxillar sinus bone grafts

Objetivo: El objetivo de la I Conferencia Española de Consenso sobre el Injerto Óseo Sinusal era intentar llegar a puntos de acuerdo sobre las principales controversias de esta técnica, aplicada de forma muy variada y con el empleo de materiales muy diversos, y conseguir plasmar los mismos en un documento resumen consensuado por todos los autores. Material y método: Durante los días 17 y 18 de octubre de 2008 se celebró en Oviedo la citada conferencia, auspiciada por la Sociedad Española de Cirugía Oral y Maxilofacial. En ella se dieron cita un total de 50 ponentes de reconocido prestigio nacional e internacional que repasaron en 6 mesas de trabajo las principales controversias sobre los injertos óseos sinusales. Tras las conferencias de los ponentes, los moderadores establecían las principales conclusiones de cada mesa y se abría un turno de debate donde participaban todos los asistentes. Resultado: Este documento y sus conclusiones emanan de las presentaciones realizadas por los ponentes y de las deliberaciones y acuerdos de cada mesa de trabajo. Ambos han sido aprobados tras varias correcciones por todos los autores antes de ser enviados para su publicación. Además, han obtenido el reconocimiento científico oficial de la Sociedad Española de Cirugía Oral y Maxilofacial y deben servir como base para futuros estudios y reuniones científicas. Conclusiones: El objetivo fundamental cuando se realiza un injerto óseo sinusal es la formación de hueso vital en el seno maxilar, para conseguir la supervivencia a largo plazo de los implantes tras su carga protésica. Para ello, la técnica y la secuencia de tratamiento deben orientarse a conseguir resultados predecibles y estables en el tiempo, aunque esto suponga un mayor tiempo de espera hasta la colocación de la prótesis. La estabilidad inicial del implante es el factor clave para la osteointegración y debe ser el principal criterio para indicar implantes simultáneos o diferidos en el seno maxilar(AU)

Objective: The objectives of the first Spanish Consensus Conference on Sinus Bone Graft were trying to reach agreements points on the major controversies of this technique, and translate them in a summary document. Material and method: During the 17th and 18th of October of 2008 took place in Oviedo (Spain) the Conference, sponsored by the Spanish Society of Oral and Maxillofacial Surgery. There, 50 national and international speakers reviewed in 6 workshops the major controversies of sinus bone grafts. Following the conferences, the moderators proposed the main conclusions of each workshop and opened a round of discussion where all attendees participated. Results: This document and its conclusions emanate from the presentations made by the speakers and the discussions and agreements of each workshop. Both have been approved after several corrections by all authors before being submitted for publication. They have also obtained the official scientific recognition of the Spanish Society of Oral and Maxillofacial Surgery and should serve as a basis for future scientific studies and meetings. Conclusions: The main objective when we perform a sinus bone graft is vital bone formation in the maxillary sinus, to achieve long-term survival of the implants after prosthetic loading. To do this, the technique and sequence of treatment should aim to achieve predictable and stable results over time, although this involves a longer waiting time. The initial implant stability is the key factor for osseointegration and should be the main criterion to indicate simultaneous or delayed implants in the maxillary sinus(AU)

Bilateral mandibular infected buccal cyst: a new image.

BACKGROUND: The mandibular infected buccal cyst is an uncommon lesion associated with the permanent mandibular first or second molar in children just prior to tooth eruption. The World Health Organization includes this lesion under the category of paradental cyst and suggests the term "mandibular infected buccal cyst" (MIBC) for lesions that occur on the buccal surface of the permanent mandibular first molar in children approximately 6 to 8 years of age. We present the case of a patient with bilateral mandibular cyst affecting the second molars of an 8-year-old boy. To the best of our knowledge, this is the first case of bilateral MIBC published with a three-dimensional model made using an interactive three-dimensional (3D) implant planning system. METHODS: An 8-year-old boy presented with swelling over the buccal gingiva of his lower left first molar. He complained of pain on chewing. Clinical examination revealed a 10-mm, firm, round swelling buccal to the lower left first molar. Computed tomography with multiplanar reconstruction of the jaws showed well-defined bilateral ovoid radiolucencies at the apices of the lower left first molar and the lower right first molar. A three-dimensional study was made using the interactive 3D implant planning system showing the presence of the cyst and its relation with the molar and the dental nerve. The treatment was to enucleate the left cyst and maintain the involved tooth. RESULTS: The histopathologic diagnosis of the lesion was an MIBC. CONCLUSION: The objective of the present study is to 1) familiarize dentists and oral surgeons with the entity of the MIBC; 2) show new image techniques for the diagnosis; and 3) emphasize the appropriate treatment approach.

Medicina basada en la evidencia (MBE). Ventajas / Evidence Based Medicine (EBM). Advantages

La Medicina basada en la Evidencia (MBE) se define como un proceso cuyo objetivo es la selección de los mejores argumentos científicos para la resolución de los problemas que la práctica médica cotidiana plantea. Filosóficamente es un nuevo paradigma (verificacionista), que se ha extendido a todas las profesiones sanitarias (Cirugía Basada en la Evidencia, Odontología Basada en la Evidencia, etc.), soportado por los avances tecnológicos. Aunque sus ventajas son evidentes, también se han reconocido limitaciones, especialmente en lo concerniente a la práctica quirúrgica. En el presente trabajo se revisan los fundamentos y principales ventajas de la MBE. (AU)

Injertos óseos en cirugía implantológica: aspectos generales. Principios y fundamentos / Bone grafts in implantologic surgery. General aspects. Principles and fundaments (Part 1)

Los injertos óseos constituyen una de las técnicas de más frecuente uso en la cirugía reconstructiva implatológica. El material de elección para el reemplazo del hueso perdido por atrofia, traumatismo, procesos patológicos congénitos o adquiridos son los injertos óseos autógenos. En la curación del injerto óseo pueden intervenir fenómenos de osteogénesis, osteoconducción y osteoinducción. Los injertos óseos esponjosos se revascularizan antes que los injertos corticales. Los injertos de hueso de origen membranoso se reabsorben menos que los de origen endocondral. Los injertos óseos pueden ser colocados como bloques (corticales o corticoesponjosos) o particulados. Los injertos en bloque deben ser fijados con tornillos de oseosíntesis. Las tasas de éxito de los implantes superan el 80 por ciento en el maxilar superior y el 90 por ciento en la mandíbula. La causa más frecuente de complicaciones con los injertos en bloque es consecuencia de la dehiscencia de la mucosa, con exposición del injerto al medio intraoral. La instalación de las fijaciones en un segundo tiempo (diferidas a la reconstrucción ósea), permite la colocación más precisa de los implantes para su posterior rehabilitación prostodóntica (AU)

Injertos óseos en cirugía implantológica: técnicas quirúrgicas en el maxilar y la mándíbula / Bone grafts in implantologic surgery. Surgical techniques in the maxilla and mandible (Part II)

Los injertos óseos constituyen una de las técnicas de más frecuente uso en la cirugía reconstructiva implantológica. El material de elección para el reemplazo del hueso perdido son los injertos óseos autógenos. En los últimos 20 años se han publicado diferentes técnicas de reconstrucción ósea combinadas con implantes. Los injertos en bloque pueden colocarse por aposición a la cresta alveolar ("onlay graft"), interposición bajo el suelo del seno, de las fosas nasales, o de la cresta alveolar desdoblada con escoplos ("inlay graft"), por vestibular de la cresta atrófica ("veneer graft") o en silla de montar ("saddle graft", para tratar simultáneamente los problemas de deficiente altura y anchura). Los injertos esponjosos pueden colocarse bajo membranas de regeneración ósea guiada (ROG), mallas de titanio, en el suelo del seno o en el interior de cavidades óseas. La causa más frecuente de complicaciones con los injertos en bloque es consecuencia de las dehiscencia de la mucosa, con exposición del injerto al medio intraoral. La instalación de las fijaciones en un segundo tiempo (diferidas a la reconstrucción ósea), permite la colocación más precisa de los implantes para su posterior rehabilitación prostodóntica. (AU)

[Involvement of the submadibular region in epidermoid carcinoma of the mouth floor. Prospective study of 31 cases]. / Coinvolgimento della regione sottomandibolare nel carcinoma epidermoide del pavimento orale. Studio prospettico di 31 casi.

BACKGROUND: To evaluate the primary or secondary involvement of the submandibular gland in floor of mouth squamous cell carcinoma. METHODS: An analytic-observational study of prospective type was carried out on 31 patients operated for floor of mouth carcinoma, between June 1993 and January 1996, in a reference hospital for a population of 1,100,000 inhabitants. The investigated variables were: age, sex, tumor localization, clinical TNM, type of cervical surgery, evolution, number of positive cervical metastasis, state of the submandibular gland and presence of the periglandular metastasis. The follow-up period was about 48 to 76 months. The exact Fischer test was used for the statistical study. RESULTS: Histopathological examination identified cervical metastasis as 34.1% of the ipsilateral neck dissections. The average number of positive nodes was 3 (range: 1-9). Cervical periglandular metastases were found in 31.7% of neck dissections, but in no case was microscopic affectation of the submandibular gland found. The existence of intraglandular positive nodes was not found either. In our study, the sensibility and specificity of the clinical exploration of the submandibular region were high (84% and 88% respectively). The presence of cervical metastasis and the size of the tumor conditioned the appearance of recurrences. CONCLUSIONS: In accordance with our study, periglandular metastases in carcinoma of the floor of mouth, are frequent, but submandibular gland involvement is unusual.

Stafne bone cyst. Revision of four cases, one of them with bilateral affectation.

Stafne bone cyst of the mandible is the only described destructive bone lesion that is highly localized, nonprogressive, but nonhealing. Such defects usually occur unilaterally, however, bilateral defects are occasionally reported. This paper reports 4 cases of Stafne's bone cyst, one of which showed bilateral presentation. Only four previous cases of bilateral Stafne bone cyst have been reported in the literature. The bibliography is reviewed with regard to the incidence, plausible etiologic factors and methods of diagnosis of such lesions.

Densitometric evaluation of changes in the soft tissue of the chin and the lower lip during the treatment of Class III malocclusion.

The aim of this study was to use densitometry of lateral skull teleradiographs to evaluate the changes that occurred in the lower lip and chin after orthodontic or orthodontic-surgical treatment of Class III malocclusion. Forty teleradiographs from 20 patients with mandibular prognathism were made at the beginning and end of treatment. In ten of these patients the treatment was exclusively orthodontic with an edgewise appliance, and in another ten the treatment was orthodontic with a straight wire appliance combined with orthognathic and mentoplastic surgery. In the patients who were only treated orthodontically, a significant increase in density of the lower lip and the chin was found after treatment. This seemed to be related to an increase of muscular tension in these areas. Patients treated with orthognathic surgery and the straight wire appliance showed a decrease in density of the chin after treatment, but not of the lip. This can be interpreted as a consequence of muscular normalization after this procedure was accomplished.
