RESUMO
Purpose: To evaluate the association between allergic sensitivity and pollen counts in patients with allergic respiratory disease (ARD) and its relationship with atmospheric pollutants. Methods: From 2012 to 2018, we evaluated the sensitivity by skin prick test in ARD patients. The pollen counts were analyzed according to international guidelines (2014-2018). The pollutant and meteorological data were obtained at the same time from AIRE-CDMX websites. We analyzed the association between allergic sensitivity and pollen counts using the χ2 test and stratified by disease allergic rhinitis (AR) and AR with asthma (ARwA), periods (before/after 2015), and pollination seasons (S1:2014-2015), (S2:2015-2016), (S3:2016-2017), (S4:2017-2018). Likewise, we correlated the pollen counts with the concentrations of pollutants using Pearson's correlation. For all analyses, we used SPSS v.21 software, and a p-value <0.05 was considered significant. Results: A total of 520 patients were enrolled, of whom 67.3% had ARwA and 33.7% had AR (p<0.05). The frequency of patients allergic to at least one pollen was higher compared with patients sensitive to indoor allergens (55.3% vs 44.6%, p<0.001). A total of 46.8% of the patients were only sensitive to trees in comparison to other outdoor allergens (p<0.001). The Fraxinus sp. and the Cupressaceae family allergens were approximately two times more frequent than the other tree allergens in both diseases (p<0.05). These pollens doubled their counts since 2015 (p<0.001), which was associated with increases in sensitivity for Fraxinus sp. and the Cupressaceae family compared to previous years (p<0.001). Regarding pollutants, the most significant correlations were with PM10, NO2, PMCO for Fraxinus sp. pollen concentrations in all seasons (p≤0.02). Conclusion: The high increases in pollen counts of the Fraxinus sp. and Cupressaceae family were associated with increases in the frequency of sensitization to these species, and this phenomenon correlated with increases in PM10, NO2, and PMCO.
RESUMO
Resumen ANTECEDENTES: El embarazo ectópico abdominal es una alteración poco frecuente, sin tratamiento definido hasta ahora. La extracción quirúrgica del feto y la aplicación de metotrexato representan una opción de tratamiento en pacientes con embarazo ectópico abdominal. CASO CLÍNICO: Paciente de 36 años, con 16.2 semanas de embarazo, que acudió al servicio de urgencias por un cuadro de dolor en el epigastrio. El ultrasonido pélvico y la tomografía computada evidenciaron una imagen sugerente de feto sin vitalidad en el hipocondrio derecho. La laparotomía exploradora objetivó un feto masculino, de 115 g, cubierto con epiplón en el mesogastrio, extraído sin dificultad. No se retiró el tejido placentario, pues se encontraba adherido al tejido intestinal. El tratamiento consistió en múltiples dosis de metotrexato. La paciente evolucionó satisfactoriamente y fue dada de alta sin complicaciones. CONCLUSIÓN: El tratamiento combinado (laparotomía para la extracción del feto y administración posterior de metotrexato) es una opción efectiva en pacientes con embarazo ectópico abdominal no complicado, con tejido placentario adherido en zonas sumamente vascularizadas.
Abstract BACKGROUND: Abdominal ectopic pregnancy is a rare entity which treatment has not been clearly stablished. One of the therapeutic alternatives is the surgical extraction of the fetus and the subsequent application of methotrexate in these patients. CLINICAL CASE: A 36-year-old female patient came to the emergency unit complaining of pain in the epigastrium. The patient referred a pregnancy of 16.2 weeks. Pelvic ultrasound and computed tomography were performed, demonstrating a suggestive image of a fetus without vitality at the level of the right hypochondrium. An exploratory laparotomy was performed. A male 115 gram fetus was observed at the level of mesogastrium, and was extracted without difficulty. Placental tissue was not removed because it was adhered to intestinal tissue. The subsequent management consisted of methotrexate. The patient was discharged without complications. CONCLUSION: The combined therapy between laparotomy for the extraction of the fetus and administration of methotrexate may be viable for cases of uncomplicated abdominal ectopic pregnancy in which the placental tissue is adhered to highly vascularized areas.
