Laparoscopic antireflux surgery in patients with extra esophageal symptoms related to asthma

Asthma, laryngitis and chronic cough are atypical symptoms of the gastroesophageal reflux disease. To analyze the efficacy of laparoscopic surgery in the remission of extra-esophageal symptoms in patients with gastroesophageal reflux, related to asthma. Were reviewed the medical records of 400 patients with gastroesophageal reflux disease submitted to laparoscopic Nissen fundoplication from 1994 to 2006, and identified 30 patients with extra-esophageal symptoms related to asthma. The variables considered were: gender, age, gastroesophageal symptoms (heartburn, acid reflux and dysphagia), time of reflux disease, treatment with proton pump inhibitor, use of specific medications, treatment and evolution, number of attacks and degree of esophagitis. Data were subjected to statistical analysis, comparing the pre- and post-surgical findings. The comparative analysis before surgery (T1) and six months after surgery (T2) showed a significant reduction on heartburn and reflux symptoms. Apart from that, there was a significant difference between the patients with daily crises of asthma (T1 versus T2, 45.83% to 16.67%, p=0.0002) and continuous crises (T1, 41.67% versus T2, 8.33%, p=0.0002). Laparoscopic Nissen fundoplication was effective in improving symptoms that are typical of reflux disease and clinical manifestations of asthma.Asthma, laryngitis and chronic cough are atypical symptoms of the gastroesophageal reflux disease.

Otimização da aplicação de Fluazifop-P-Butil em pós-emergência na cultura de soja (Glycine max) Optimizing Fluazifop-P-Butyl application on postemergence soybeans (Glycine max)

O objetivo deste trabalho foi avaliar a possibilidade de redução da dosagem e do volume de calda em função do horário de aplicação do herbicida fluazifop-p-butil em pós-emergência na cultura de soja, mantendo-se o controle das plantas daninhas e a seletividade para a cultura. O experimento foi conduzido na área experimental da Fazenda de Ensino e Pesquisa da FCAV/UNESP - Jaboticabal, no ano agrícola 1998/99, na cultura de soja, cultivar FT 2009. O delineamento experimental utilizado foi o de blocos ao acaso com 24 tratamentos, sendo 20 dispostos no esquema fatorial 2 x 2 x 5 e quatro testemunhas. Os fatores testados foram: volume de calda (100 e 200 L de calda/ha); dosagens reduzidas -75,2 e 112,8 g de fluazifop-p-butil/ha (respectivamente a 40 e 60% da dosagem recomendada); e horário de aplicação (5, 9, 13, 17 e 21 horas). As testemunhas foram aplicadas com a dosagem recomendada (188,0 g do fluazifop-p-butil/ha) e com os volumes de 100 e 200 L de calda/ha, no mato (sem controle das plantas daninhas) e "no limpo" (plantas daninhas controladas com enxada manual). As principais espécies de plantas daninhas que emergiram na área experimental foram capim-carrapicho (Cenchrus echinatus), que compunha 60% da comunidade infestante; capim-colchão (Digitaria horizontalis), 10%; e capim-pé-de-galinha (Eleusine indica), 30%. Todas as aplicações do herbicida fluazifop-p-butil, nos horários até as 9 horas e a partir das 17 horas, controlaram eficientemente as três espécies de plantas daninhas e foram seletivas para a cultura de soja. Portanto, o uso do herbicida fluazifop-p-butil pode ser otimizado por meio de reduções na dosagem e no volume de calda em aplicações durante os horários com condições ambientais favoráveis à pulverização.<br>The objective of this study was to evaluate the possibility of reducing spray concentration and volume of Fluazifop-p-butyl applications on postemergence soybeans, while maintaining weed control and growth selectivity. The study was conducted in the experimental area of the Teaching and Research Farm of FCAV/Unesp - Jaboticabal Campus, during the agricultural season of 1998/99, carried out on a crop of soybean cultivar FT 2009. The experimental setup utilized was a randomized block design with 24 treatments, 20 following a factorial scheme 2 x 2 x 5 and 4 control treatments. The factors examined were: spray volume (100 and 200 L ha-1); reduced spray concentration - 75.2 and 112.8 g of fluazifop-p-butyl/ha (40 and 60% of the recommended concentration, respectively); and application schedule (5 A.M., 9 A.M., 1 P.M., 5 P.M. and 9 P.M.). The controls were applications at the recommended concentration (188.0 g fluazifop-p-butyl/ha), using volumes of 100 and 200 L ha-1, and treatments without weed control and weeds controlled with manual hoeing. The main species of weeds that emerged in the experimental area were: Cenchrus echinatus, comprising 60% of the infested sections; Digitaria horizontalis, 10%, and Eleusine indica, 30%. All fluazifop-p-butyl applications made up to 9 A.M. and from 5 P.M. effectively controlled the three species of weeds and provided a selective growth of soybeans. Therefore, the use of fluazifop-p-butyl can be optimized by reducing both the concentration and the volume of the spray for applications times providing favorable conditions for crop dusting
