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 , 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.

Abstract: Analytical calculations of the potential and electric field distributions based on 2D-models for different electrode arrays are performed by solving the Laplace equation, meanwhile the numerical solution is solved by means of finite element method in two dimensions.Both analytical and numerical solutions reveal significant differences between the electric field distributions generated by electrode arrays with shapes of circle and different conic sections (elliptic, parabolic and hyperbolic). Electrode arrays with circular, elliptical and hyperbolic shapes have the advantage of concentrating the electric field lines in the tumor.The mathematical approach presented in this study provides a useful tool for the design of electrode arrays with different shapes of conic sections by means of the use of the unifying principle. At the same time, we verify the good correspondence between the analytical and numerical solutions for the potential and electric field distributions generated by the electrode array with different conic sections.Electrotherapy is the use of electrical energy as a medical treatment and it was introduced to destroy solid tumors at the end of nineteenth century. Many physicians have successfully used this therapy, also known as electrochemical tumor therapy, Galvanotherapy and electro-cancer treatment, as a standalone treatment in thousands of cases, with some truly spectacular results [1-4]. Electrotherapy of a low-level direct current is used to treat the cancer (target tissue) through two or more platinum (platinum-iridium 90/10, stainless steel) electrodes placed in or near the malignant tumor. In this therapy, two modes are used with similar results: voltage mode (voltage keeps constant and direct current intensity varies due to changes in the tumor resistance) and current mode (direct current intensity keeps constant for voltage variations because the tumor resistance is altered). In both modes, the tumor electrical resistance variations may be ex

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.
