ABSTRACT
BACKGROUND: Pancreatectomy plus celiac axis resection (CAR) is performed in patients with locally advanced pancreatic cancer. The morbidity rates are high, and no survival benefit has been confirmed. It is not known at present whether it is the type of pancreatectomy, or CAR itself, that is the reason for the high complication rates. METHODS: Observational retrospective multicenter study. INCLUSION CRITERIA: patient undergoing TP, PD or DP plus CAR for a pancreatic cancer. RESULTS: Sixty-two patients who had undergone pancreatic cancer surgery (PD,TP or DP) plus CAR were studied. Group 1: 17 patients who underwent PD/TP-CAR (13TP/4PD); group 2: 45 patients who underwent DP-CAR. Groups were mostly homogeneous. Operating time was longer in the PD/TP group, while operative complications did not differ statistically in the two groups. The number of lymph nodes removed was higher in the PD/TP group (26.5 vs 17.3), and this group also had a higher positive node ratio (17.9% vs 7.6%). There were no statistical differences in total or disease-free survival between the two groups. CONCLUSION: It seems that CAR, and not the type of pancreatectomy, influences morbidity and mortality in this type of surgery. International multicenter studies with larger numbers of patients are now needed to validate the data presented here.

INTRODUCTION: Epidemiological studies have described a high comorbidity of substance use disorders with another psychiatric disorder, which has been called dual pathology. However, the aetiological mechanisms underlying this association are still not fully understood. AIM: To carry out a preliminary study of the effect of polymorphism rs1051730 of the gene group CHRNA5-CHRNA3-CHRNB4 through a case-control study. SUBJECTS AND METHODS: A total of 225 subjects were selected and divided into three groups: those diagnosed with bipolar disorder, those with nicotine dependence, and subjects without nicotine dependence or any other psychiatric disorder. Genotyping was performed by real-time polymerase chain reaction. Genetic association analysis was performed using chi-square tests and multivariate logistic regressions. RESULTS: On comparing allelic frequencies with the control group, we found that polymorphism rs1051730 was associated with nicotine dependence (p = 0.03), but not with bipolar disorder (p = 0.94). CONCLUSION: Variant rs1051730 was associated with nicotine dependence in the Mexican population and showed the same effect in dual pathology. However, further studies are recommended to obtain conclusive results.
TITLE: Analisis del polimorfismo rs1051730 de CHRNA3 en pacientes con patologia dual en poblacion mexicana.Introduccion. Estudios epidemiologicos han descrito una alta comorbilidad de los trastornos de uso de sustancias con otro trastorno psiquiatrico, al cual se le ha llamado patologia dual. Sin embargo, los mecanismos etiologicos de esta asociacion continuan siendo dificiles de entender. Objetivo. Realizar un estudio preliminar del efecto del polimorfismo rs1051730 del grupo de genes CHRNA5-CHRNA3-CHRNB4 a traves de un estudio de casos y controles. Sujetos y metodos. Se selecciono a un total de 225 sujetos, divididos en tres grupos: con diagnostico de trastorno bipolar, con dependencia a la nicotina y sujetos sin dependencia a la nicotina o cualquier otro trastorno psiquiatrico. La genotipificacion se realizo mediante reaccion en cadena de la polimerasa en tiempo real. El analisis de asociacion genetica se realizo mediante pruebas de chi cuadrado y regresiones logisticas multivariables. Resultados. Al comparar las frecuencias alelicas con el grupo control, encontramos que el polimorfismo rs1051730 se asocio con el grupo de dependencia a la nicotina (p = 0,03), pero no con el de trastorno bipolar (p = 0,94). Conclusion. La variante rs1051730 se asocio con dependencia a la nicotina en la poblacion mexicana y mostro el mismo efecto en la patologia dual. Sin embargo, se recomiendan estudios adicionales para tener resultados concluyentes.

BACKGROUND: Allergic rhinitis is an inflammatory disease of the nasal mucosa, with common symptoms, which is essentially characterized by nasal itching, nasal congestion, sneezing, hyaline rhinorrhea and repetitive sneezing. The disease is very common, 15% of the population worldwide suffers it. Among many treatments that have been used to relieve the symptoms of this disease there is a selective inhibitor of H1 receptors, ebastine. OBJECTIVE: To evaluate patient satisfaction using the scale of Treatment Satisfaction Questionnaire for Medication (TSQM). MATERIAL AND METHODS: A multicentric, retrospective, observational study performed in 250 Mexican patients with the diagnosis of intermittent allergic rhinitis (IAR) or persistent allergic rhinitis (PER), confirmed by prick test, specific IgE, or both, treated with lyophilised ebastine in fast-dissolving (FDT) 20 mg at any time in the last two months, prescribed for at least two weeks by their doctor to relieve the symptoms of intermittent allergic rhinitis or persistent allergic rhinitis. We used a validated questionnaire assessment scales, TSQM. RESULTS: The presentation of ebastine fast-dissolving (FDT) is effective and has good tolerability, over 80% of patients reported comfort and satisfaction using it. CONCLUSIONS: Assessment of overall satisfaction, efficacy, tolerability and comfort showed that ebastine in fast-dissolving is an antihistamine with clear benefits to encourage compliance.

Objetivo: Conocer la prevalencia de tabaquismo entre estudiantes de un Colegio de Bachilleres con la finalidad de contar con información basal para el diseño de una intervención educativa. Material y métodos: Se realizó un estudio transversal con el total de alumnos (n=490) que asistían a una escuela pública urbana en el estado de Morelos, México. Se aplicó un cuestionario, en diciembre de 2001. Como prueba estadística se llevaron a cabo diferencias de proporciones entre grupos a un nivel de confianza del 95%. Resultados: La prevalencia de tabaquismo fue del 27.3%. Los espacios en donde los adolescentes reportaron que han fumado fueron sitios públicos: fiestas (66%), discotecas (43%), y calle (46.6%). Al explorar la relación entre el tabaquismo de los adolescentes y que algún miembro de la familia también fuera adicto al tabaco se encontró un 71.6% (p=0.000). El padre es quien ocupó el primer lugar (55.01%). Entre los estudiantes fumadores el 98.5% consumían además bebidas alcohólicas (p=0.000). Conclusiones: Los datos de esta investigación son semejantes a los reportados entre estudiantes de la India y Australia, pero menores a lo señalado en países europeos (Inglaterra, Noruega) y de América (Estados Unidos, Chile). Los resultados encontrados en este estudio serán utilizados para diseñar una intervención educativa dirigida a disminuir la adicción en esta zona.
Objective: The purpose of this study was to determine the prevalence of smoking in High School students in order to have significant information to design an educative intervention. Material and methods: A transversal exploratory study was performed on 490 students of a public urban Highs School in the State of Morelos, Mexico. A survey was applied in December, 2001. Statistical analysis was done by proportion differences between groups with a confidence level of 95%. Results: Smoking habit prevalence was 27.3%. Teenagers reported to smoke in public places: parties (66%), nightclubs (43%), street (46.6%). The relationship between smoking habits in teenagers and having a relative who is also a tobacco addict was 71.6% (p=0.000). The father held the first place (55.01%). Among smoking teenagers, 98.5% also drank alcoholic beverages (p=0.000). Conclusion: These results are similar to those reported for students in India and Australia, but lower than those for European countries (Great Britain and Norway), and America (USA, Chile). Results of this study will be used to design an educational intervention directed to diminish addiction in this area.
