Creencias tradicionales mexicanas y su relación con la aceptación de la autotoma vaginal para la detección del VPH / Traditional Mexican beliefs and their relationship with the acceptance of vaginal self-sampling for HPV detection

Resumen OBJETIVO: Conocer el grado de aceptación de la autotoma vaginal y su relación con variables psicosocioculturales que prevalecen en México. MATERIALES Y MÉTODOS: Estudio observacional, prospectivo, transversal y descriptivo, efectuado entre 2017 y 2018 en mujeres del estado de Guanajuato. Se aplicaron cuestionarios y entrevistas antes y después de la toma de la muestra mediante la autotoma. El análisis estadístico incluyó medidas de tendencia central, medidas de dispersión, frecuencias y proporciones. Las diferencias entre grupos se analizaron con las pruebas de Wilcoxon y t de Student. RESULTADOS: Se estudiaron 85 mujeres con edad promedio de 37.82 años (± 9.82). Si bien 75 participantes declararon no conocer el procedimiento, 80 accedieron a practicarlo. Se encontró que la mayoría de las mujeres prefiere la autotoma a la inspección ginecológica tradicional. Se observaron dos perfiles sociopsicológicos opuestos entre las mujeres que prefieren la autotoma por "pena" y las que optan por ella por su "facilidad". CONCLUSIONES: La autotoma fue un método de muestreo completamente viable en el contexto en el que se llevó a cabo esta investigación. Si bien se observaron barreras psicosocioculturales, la autotoma se prefirió entre las mujeres que informaron acudir menos al ginecólogo, por lo que puede constituir una estrategia para las mujeres con baja vigilancia médica.

Abstract OBJECTIVE: To know the degree of acceptance of vaginal autotomy and its relationship with psychosocial-cultural variables prevailing in Mexico. MATERIALS AND METHODS: Observational, prospective, cross-sectional and descriptive study, carried out between 2017 and 2018 in women in the state of Guanajuato. Questionnaires and interviews were applied before and after sampling by autotoma. Statistical analysis included measures of central tendency, measures of dispersion, frequencies and proportions. Differences between groups were analyzed with Wilcoxon and Student's t-tests. RESULTS: Eighty-five women with a mean age of 37.82 years (± 9.82) were studied. Although 75 participants stated that they were unaware of the procedure, 80 agreed to undergo it. It was found that the majority of women preferred autotoma to traditional gynecological inspection. Two opposite socio-psychological profiles were observed between women who prefer autotomy for "embarrassment" and those who opt for it because of its "ease". CONCLUSIONS: Autotomography was a completely feasible sampling method in the context in which this research was conducted. Although psychosocio-cultural barriers were observed, autotoma was preferred among women who reported less frequent visits to the gynecologist, so it may be a strategy for women with low medical vigilance.

The PhtL protein of Pseudomonas syringae pv. phaseolicola NPS3121 affects the expression of both phaseolotoxin cluster (Pht) and Non-Pht encoded genes.

Pseudomonas syringae pv. phaseolicola, the causal agent of halo blight disease in bean, produces a toxin known as phaseolotoxin, whose synthesis involves the products of some of the genes found within the Pht region. This region, considered a pathogenicity island, comprises 23 genes arranged in five transcriptional units: two single-gene units (argK, phtL) and three arranged as operons (phtA, phtD, phtM), most with unknown function. In P. syringae pv. phaseolicola, maximal expression of most of the genes encoded in the Pht region and the synthesis of phaseolotoxin require the product of the phtL gene, of unknown function but that has been proposed to have a regulatory role. In order to evaluate the role of phtL gene in P. syringae pv. phaseolicola, we performed a comparative transcriptional analysis with the wild type and a phtL(-) mutant strains using microarrays. The microarray data analysis showed that PhtL regulates the expression not only of genes within the Pht region, but also alters the expression of genomic genes outside it, indicating that this gene has been integrated into the regulatory machinery of the bacterium. The expression changes of many of those genes were confirmed by RT-PCR. This study also demonstrated the importance of the PhtL protein in the process of iron response, and suggests that the effect of PhtL on the expression of pathogenicity related, respiration and oxidative stress genes, observed in this study, appears to be indirect through its influence on the Fur protein expression.

[Chronic calcified hematocele. Case report]. / Hematocele crónico calcificado. A proposito de un caso.

OBJECTIVE: Chronic hematoceles are rare scrotal masses. Most of them include trauma, torsion, tumor, and surgery as possible causes. We describe the case of an old diabetic patient, who is attended for presenting a marked increase in size of the right hemiescrotum and pain. METHODS: We described computed tomography and sonographic findings. RESULTS/CONCLUSIONS: Frequently, a varicocele is an associated finding. Presumibly, minor trauma results in rupture of dilated vessels. In sonographic exploration, they have a more complex heterogeneous appearance with echogenic debris and septations. Most hematoceles spontaneously resolve with conservative therapy.
