ABSTRACT
Nasopharyngeal carcinoma (NPC) is one of the common head and neck malignant tumors. Radiotherapy is the main treatment for NPC. The comprehensive application of chemotherapy strategies (induction, concurrent and adjuvant) in radiotherapy has improved the efficacy in the treatment of locally advanced NPC. Based on current evidence, concurrent chemoradiotherapy combined with adjuvant or induction chemotherapy has been recommended as the standard treatment for locally advanced NPC. However, there are still many deficiencies in the standard treatment, and the application of induction and adjuvant chemotherapy remains controversial. Establishing a more ideal and individualized chemoradiotherapy for locally advanced NPC is still the research direction in the future.
ABSTRACT
Objective:To evaluate the quality of root filling with Resilon/Epiphany Self-Etch(RESE).Methods:30 recently extrac-ted mandibular premolars were randomly divided into 2 groups.After root canal preparation,the roots in experimental group(n =1 4) were filled with RESE,those in control group(n =1 6)were filled with Gutta-percha/AH plus.The quality of the optical obturation was evaluated by X-ray photography.Results:The buccolingual X-ray scores of the two filling materials were higher than the mesiodistal sores(P 0.05).The mesiodistal X-ray score of RESE group was higher than that of Gutta-percha/AH plus group(P <0.05).Conclusion:The X-ray resistance of the RESE filling system is more favorable than Gutta-percha/AH plus for the evaluation of root filling quality by X-ray examination.
ABSTRACT
El Primer Encuentro Internacional de Institutos de Medicina Tropical, llevado a cabo en Lima, fue la actividad principal del cincuentenario de la fundaci¢n del Instituto de Medicina Tropical Daniel A. Carri¢n (1963-2013), de la Facultad de Medicina de la UNMSM. Participaron en su organizaci¢n las principales instituciones cient¡ficas del pa¡s relacionadas a la investigaci¢n y atenci¢n de los problemas de salud que afectan a las regiones tropicales y subtropicales. Asistieron alrededor de mil personas. Los temas tratados fueron salud infantil en los tr¢picos, salud internacional, VIH/sida, dengue, malaria, leishmaniosis, tuberculosis, enfermedad de Carri¢n y enfermedades emergentes y reemergentes. Los representantes de los nueve institutos de Medicina Tropical de la regi¢n, asistentes al evento, suscribieron una declaraci¢n, en la que acordaron, entre otros puntos, promover en sus pa¡ses las recomendaciones adoptadas en la Asamblea Mundial de la Salud y Organizaci¢n Panamericana de la Salud en relaci¢n a enfermedades desatendidas, investigaci¢n en salud y recursos humanos en salud; desarrollar programas de posgrado regionales en medicina tropical, epidemiolog¡a y salud p£blica; articular las acciones de este encuentro con otras iniciativas regionales y subregionales, y realizar el Segundo Encuentro Internacional de Institutos de Medicina Tropical en dos a¤os.
The First International Meeting of Tropical Medicine Institutes held in Lima was the main event of the 50th anniversary of the establishment of the Daniel A. Carrion Tropical Medicine Institute (1963-2013), Faculty of Medicine at UNMSM. The major Peruvian scientific institutions for research and management of global health burdens affecting tropical and subtropical regions participated in the organization of this event. About one thousand people attended. Topics included child health in the tropics, international health, HIV/AIDS, dengue, malaria, leishmaniasis, tuberculosis, Carrion's disease and emerging diseases. Representatives of the nine institutes of Tropical Medicine of the region who attended the event signed a declaration in which all represented institutes agreed to promote in their respective countries the recommendations of the World Health Assembly and the Pan American Health Organization in relation to neglected diseases, health research and health human resources; to develop regional graduate programs in tropical medicine, epidemiology and public health; to coordinate the activities of this meeting with other regional and subregional initiatives. The declaration also decreed, among other topics, that the participating institutes will hold the Second International Meeting of Institutes of Tropical Medicine in two years.

Este estudo procura avaliar o efeito da ordem de apresentação dos estímulos, do entrevistador e do local de realização e horário de realização da coleta de dados nos resultados de uma pesquisa psicossocial. No primeiro caso, foi avaliado o efeito de ordem na apresentação dos estímulos. Os resultados evidenciaram a ausência de qualquer efeito de ordem, uma vez que independentes da ordem de apresentação das cenas, os resultados foram os mesmos. O entrevistador exerceu um efeito apenas modesto, pois das quatro entrevistadoras, observou-se diferença estatística significativa apenas nas respostas obtidas por uma delas. Em relação ao local das entrevistas, um único apresentou uma diferença significativa, e ainda assim, em apenas uma das cenas avaliadas. Por fim, no caso do horário de realização da coleta não foram observadas diferenças significativas nos resultados. Os dados indicam que os efeitos dos fatores contingenciais não parecem ser decisivos nos resultados da pesquisa.
his study is for evaluating the effects of thesequence in which the different stimulus arepresented, the interviewer, the place of theexperiment and the time of the data-collectingprocedure. In the first instance, it was evalu-ated the effect determined by the order in asequence of stimulus. The results revealed theabsence of any effect determined by thesequence order, since they were the sameindependently of the variations applied to thesequence. The effect determined by the inter-viewer, by its turn, provoked only a singlesubtle result, because, considering the factthat there were four women acting as intervi-ewer, only in the answers obtained by one ofthem it was noted significant statistics differen-ces and, even so, only in one of the six scenesused in the experiment. Concerning the vari-ation of places, from among the five siteswhere the data-collecting procedure was car-ried out, also only one presented a significantresult difference. At last, as regards the hourwhen the data-collecting procedure is carriedout, also only one of the four different hourspresented a relevant statistic difference inresult. Those results indicate, therefore, thatthe effect of the contingential factors does notseem to be decisive in spite of all the cautionsadopted by the researcher

Non-alcoholic duct-destructive chronic pancreatitis is a new entity that differs morphologically and pathogenetically from alcoholic chronic pancreatitis. Some clinical and imaging features of this entity resemble those of pancreatic cancer, and hence most of the reported cases underwent pancreatic resections including an invasive pancreaticoduodenectomy. Recognition of this new entity before a definitive treatment is therefore important to avoid an unnecessary pancreatic resection. Recently, we experienced a case of non-alcoholic duct-destructive chronic pancreatitis in an 80-year-old man presenting with obstructive jaundice and whose radiologic features were characteristic as originally described. Recognition of this new entity before definitive treatment enabled us to manage this patient optimally. In addition, the relation between non-alcoholic duct-destructive chronic pancreatitis and chronic pancreatitis with diffuse irregular narrowing of the main pancreatic duct is discussed.
