Rinofima severo
Tronocoso R,Antonio; Torrealba P,Ramón; Bozán S,Fernando; Lazo C,ángel;
Revista chilena de cirugía , 2012, DOI: 10.4067/S0718-40262012000200015
Abstract: rhinophyma is a progressively growing benign tumor that has the ability to distort the nasal form. even though, it is considered a rare subtype of rosacea, it is of great importance for the ability to create: psychic, aesthetic and functional disorders. this report describes a severe case of rhinophyma in a 52 years old male patient, the medical treatment and the surgical technique used for removal.

Abstract: El Rinofima es un tumor benigno de crecimiento progresivo con la capacidad de provocar severas alteraciones en la morfología nasal. Es considerado un subtipo de rosácea poco frecuente, sin embargo, es de gran relevancia por su capacidad de crear trastornos tanto estéticos como funcionales y psicológicos en las personas afectadas. Este reporte describe un caso severo de rinofima, en un paciente de género masculino de 52 a os, el tratamiento médico y la técnica quirúrgica que se utilizó para su remoción.

Enfermedad de Chagas crónica.Ausencia de Triatoma infestans intradomiciliario y persistencia de Trypanosoma cruzi circulante post-terapia CHRONIC CHAGAS DISEASE. ABSENCE OF INTRADOMICILIARY Triatoma infestans AND PERSISTENCE OF CIRCULATING POST-THERAPY Trypanosoma cruzi circulante post-terapia

Abstract: En el a o 1999, se certificó en Chile la interrupción de la transmisión vectorial de la enfermedad de Chagas. Por otra parte, el desarrollo de políticas habitacionales, que incluyen zonas rurales endémicas, han logrado importantes avances en grupos humanos que presentaban graves deficiencias de habitabilidad. En esta situación epidemiológica, se estudió 10 a os después de la terapia, a 37 chagásicos crónicos procedentes de zonas rurales de la IV Región, mediante encuesta epidemiológica (pre y post-terapia) y evaluación parasitológica (post-terapia). La encuesta incluyó: conocimiento del vector, triatominos en el domicilio actual, antecedentes de haber sido picado por triatominos y material de la construcción de la vivienda. La evaluación parasitológica se realizó mediante xenodiagnóstico (XD) (37 casos) y Reacción en Cadena de la Polimerasa (PCR) en sangre periférica (34 casos). Los resultados de la encuesta epidemiológica evidenciaron cambios importantes en la calidad de la vivienda rural de los chagásicos tratados, mientras que, en relación a la parasitemia, se detectó Trypanosoma cruzi circulante en el 89,2% de los casos (37,8% y 88,2%, mediante XD y PCR, respectivamente). Se concluye que la persistencia del parásito en condiciones post-terapia, no está relacionada con la presencia de Triatoma infestans intradomiciliario In 1999 Chile declare no vectorial transmission of Chagas disease. On the other hand, the development of dwelling policy which include endemic rural zones, have obtained important advances in human groups with height deficiency of habitability. This epidemiological situation was studied 10 years after therapy, in 37 chronic chagasic patients from rural zones of the VI Region, by an epidemiologic inquest (pre and post-therapy) and parasitological evolution (post therapy). The inquest included: knowledge of the vector, presence of triatomines in the dwelling antecedents of have been bitten by triatomines, and construction materials of the dwellings. The parasitological evolution was performed by xenodiagnosis (XD) (37 cases) and Polimerase Chain Reaction (PCR) in peripherical blood (34 cases). The results of the epidemiological survey evidenced important changes of the quality of the rural dwelling of the treated chagasic patients, while, in relation to parasitemia, circulant Trypanosoma cruzi was detected in the 89.2% of the cases. (37.8%) and 88.2% by XD and PCR respectively. It is concluded that the persistence of the parasite after therapy is not relationated with the presence of intradomiciliary Triatoma infestans
Theoretical Investigation of Local Electron Temperature in Quantum Hall Systems

Physics , 2012, DOI: 10.1016/j.physe.2012.02.020
Abstract: In this work we solve thermo-hydrodynamical equations considering a two dimensional electron system in the integer quantum Hall regime, to calculate the spatial distribution of the local electron temperature. We start from the self-consistently calculated electrostatic and electrochemical potentials in equilibrium. Next, by imposing an external current, we investigate the variations of the electron temperature in the linear-response regime. Here a local relation between the electron density and conductivity tensor elements is assumed. Following the Ohm's law we obtain local current densities and by implementing the results of the thermo-hydrodynamical theory, calculate the local electron temperature. We observe that the local electron temperature strongly depends on the formation of compressible and incompressible strips.
Evanescent incompressible strips as origin of the observed Hall resistance overshoot

Abstract: In this work we provide a systematic explanation to the unusual non-monotonic behavior of the Hall resistance observed at two-dimensional electron systems. We use a semi-analytical model based on the interaction theory of the integer quantized Hall effect to investigate the existence of the anomalous, \emph{i.e} overshoot, Hall resistance $R_{H}$. The observation of the overshoot resistance at low magnetic field edge of the plateaus is elucidated by means of overlapping evanescent incompressible strips, formed due to strong magnetic fields and interactions. Utilizing a self-consistent numerical scheme we also show that, if the magnetic field is decreased the $R_{H}$ decreases to its expected value. The effects of the sample width, temperature, disorder strength and magnetic field on the overshoot peaks are investigated in detail. Based on our findings, we predict a controllable procedure to manipulate the maxima of the peaks, which can be tested experimentally. Our model does not depend on specific and intrinsic properties of the material, provided that a single particle gap exists.
