Revista Cubana de Estomatolog?-a , 2009,
Abstract: Propósito: Presentar 3 casos de fascitisnodular de región facial. Método: Se realizó un estudio de los pacientes que comprendió examen físico, análisis de laboratorio y radiológico. Se describió la conducta quirúrgica o médica realizada en cada caso y su diagnóstico anatomopatológico. Resultados: Se mostró el método científico como única vía de llegar al diagnóstico certero, a pesar de enfrentar el reto de diagnosticar una entidad nosológica inusual en la cirugía maxilofacial. Se discutió la evolución de cada paciente y la literatura consultada. Conclusiones: Resulta muy útil la presentación de estos casos, pues esta tumoración presenta una localización muy poco frecuente en cara y su rápido crecimiento y evolución clínica son habitualmente difíciles de interpretar.

Towards a Proper Assignment of Systemic Risk: The Combined Roles of Network Topology and Shock Characteristics
Lasse Loepfe, Antonio Cabrales, Angel Sánchez
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0077526
Abstract: The 2007-2008 financial crisis solidified the consensus among policymakers that a macro-prudential approach to regulation and supervision should be adopted. The currently preferred policy option is the regulation of capital requirements, with the main focus on combating procyclicality and on identifying the banks that have a high systemic importance, those that are “too big to fail”. Here we argue that the concept of systemic risk should include the analysis of the system as a whole and we explore systematically the most important properties for policy purposes of networks topology on resistance to shocks. In a thorough study going from analytical models to empirical data, we show two sharp transitions from safe to risky regimes: 1) diversification becomes harmful with just a small fraction (~2%) of the shocks sampled from a fat tailed shock distributions and 2) when large shocks are present a critical link density exists where an effective giant cluster forms and most firms become vulnerable. This threshold depends on the network topology, especially on modularity. Firm size heterogeneity has important but diverse effects that are heavily dependent on shock characteristics. Similarly, degree heterogeneity increases vulnerability only when shocks are directed at the most connected firms. Furthermore, by studying the structure of the core of the transnational corporation network from real data, we show that its stability could be clearly increased by removing some of the links with highest centrality betweeness. Our results provide a novel insight and arguments for policy makers to focus surveillance on the connections between firms, in addition to capital requirements directed at the nodes.

Abstract: El granuloma reparativo de células gigantes (GRCG) es un proceso reactivo agresivo, que aparece con mayor frecuencia en los sectores anteriores de la mandíbula y el maxilar, en ni os y adolecentes jóvenes. Constituye el 1 % de las lesiones óseas tumorales. Existe una considerable controversia acerca de si son lesiones benignas o reactivas; también desde el punto de vista de su origen, de sus características clínicas e histológicas, así como su terapéutica. En octubre de 2007 acudió un caso a consulta externa de Cirugía Maxilofacial del Hospital Pediátrico Universitario "Juan M. Márquez", con una lesión diagnosticada como GRCG agresivo, la cual provocó gran deformidad facial y osteólisis del cuerpo mandibular. Se realizaron exámenes físicos, complementarios e iconopatográfico. Se ejecutó tratamiento quirúrgico y análisis de la pieza. La paciente no tuvo alteraciones estéticas ni funcionales. Hubo ausencia de recidiva, luego de 30 meses de seguimiento. Se revisó la literatura más reciente en los sitios Med Line, Lilac, Google, con las palabras clave granuloma reparativo de células gigantes, en inglés y espa ol, para comparar nuestros procederes y resultados con otros reportes.

Revista Colombiana de Cardiología , 2010,
Abstract: Se presenta el caso de un paciente a quien se le realizó coronariografía diagnóstica la cual reportó enfermedad coronaria de tres vasos. Inmediatamente después de finalizar el procedimiento presentó paro cardiorrespiratorio, y se iniciaron maniobras de reanimación básicas y avanzadas por dos horas. Durante la reanimación se practicó angioplastia e implante de stent en la arteria circunfleja. El paciente recuperó la circulación espontánea y fue trasladado a la unidad de cuidado coronario; en el segundo día se llevó a revascularización quirúrgica miocárdica exitosa y fue dado de alta luego de dieciséis días del evento inicial sin déficit neurológico evidente. We present the case of a 57 year old patient patient who underwent a diagnostic coronariography that showed three-vessel coronary disease. He presented cardiorespiratory arrest immediately at the end of the procedure; basic and advanced resuscitation maneuvers were started during a two hours period. During the resuscitation, primary angioplasty and stent implantation in the circumflex artery was performed. The patient recovered spontaneous circulation and was transferred to the coronary care unit. On the second day, a successful myocardial revascularization was performed and was discharged 16 days after the event without evident neurological deficit.

Abstract: Las deformidades craneofaciales se deben en su mayoría a alteraciones del crecimiento y desarrollo, traumatismos y neoplasias. Con el objetivo de describir el tratamiento quirúrgico integral de estas, se realizó un estudio descriptivo transversal en 46 pacientes tratados por el Equipo Intertidisciplinario de Cirugía Craneofacial del Hospital Pediátrico Universitario "Juan M. Márquez" en el periodo comprendido entre mayo de 2003 a marzo de 2007. La deformidad más frecuente fue la craneosinostosis (57 %), específicamente la plagiocefalia (17 %). La mayoría de los pacientes fueron de piel blanca (70 %) y se intervinieron entre el 1ro.y 7mo.a os de vida (57 %), con una media de 6,3 a os. En general no hubo predilección por sexo. Se emplearon 18 diferentes técnicas quirúrgicas. Se presentaron cinco complicaciones durante el posoperatorio (11 %), una defunción (2,2 %), una oftalmoplejía (2,2 %), dos salidas de líquido cefalorraquídeo (4,4 %) y una desaturación por depresión del centro respiratorio (2,2 %). Excepto la oftalmoplejía hubo resolución de las complicaciones en un intervalo de 15 días. Los resultados reportados por este equipo, único de su tipo en el país, son relevantes al compararlos con la literatura internacional. Most of the craniofacial deformities are due to alterations of growth, development, traumata and neoplasms. To describe the integral surgical treatment of above deformities, a cross-sectional and descriptive study was conducted in 46 patients treated by the interdisciplinary staff of craniofacial surgery from the "Juan Manuel Márquez" University Children Hospital from May, 2003 to March, 2007. The more frequent deformity was the craniosynostosis (57 %), specifically the plagiocephaly (17 %). Most of patients were of white race (70 %) and were operated don between the first and the seventh year of life (57 %) for a mean of 6,3 years. Generally there wasn't sex predominance. A total of 18 different surgical techniques were used. There were 5 complications during the postoperative period (11 %), a decease (2.2 %), a ophthalmoplegia (2.2 %), two cerebrospinal fluid leakage (4.4 %) and a desaturation by depression of respiratory center (2.2 %). With the exception of ophthalmoplegia there was a resolution of complications in a 15 days interval. Results reported by this unique Cuban staff are outstanding compared with international literature.

Revista Cubana de Estomatolog?-a , 2010,
Abstract: El tumor odontogénico adenomatoide es un tumor poco frecuente derivado del epitelio odontontogénico, que contiene estructuras canaliculares con modificaciones inductivas de intensidad variable en el tejido conjuntivo. Es una lesión de crecimiento lento y poco invasiva pero que se puede asemejar a otras lesiones odontógenas de mayor agresividad como el quiste dentígero y el ameloblastoma entre otros. Su localización clásica (área de caninos superiores) nos orienta al diagnóstico y su patrón histológico ductiforme es muy propio de este tumor. Otros tumores que se encuentran dentro de este grupo son el fibroma ameloblástico, el odontoameloblastoma, el quiste odontógeno calcificante y los odontomas compuesto y complejo. Este grupo de lesiones puede o no tener formaciones de tejido duro dental dentro de ellos. Por esta razón, se presenta un paciente con este tipo de tumor, al que se le realizó estudio histopatológico, se revisó la literatura acerca de este tumor odontogénico benigno y sus características clínicas, radiográficas, tratamiento, así como los diagnósticos diferenciales que se deben tener en cuenta. The adenomatoid odontogenic tumor is an uncommon neoplasm derivative of the odontogenic epithelium containing canalicular structures with inductor modifications of variable intensity in the conjunctival tissue. It is a slow growth lesion and no much invasive but that may to be similar to other odontogenic lesions more aggressive including the dentigerous cyst and the ameloblastoma among others. Its classical location (upper canine area) guides us to diagnosis and its duct histological pattern is very typical of this tumor. Other tumors included in this group are the ameloblastic fibroma, the ameloblastic odontoma, the calcified odontogenic cyst and composed and complex odontomas. This group of lesions may or not to have formations of hard tissue inside. Thus, authors present the case of a patient presenting with this type of tumor making a histopathology study, a literature review on this benign odontogenic tumor and its clinical radiographic features, treatment, as well as the differential diagnoses to be into account.
