RESUMO
Introduction: The combination of septoplasty and turbinoplasty is a common surgical and accepted intervention to correct the nasal obstruction. The coblation submucosal reduction turbinator is a new surgical device, and it started to be used recently. On the other hand, the medial flap inferior turbinoplasty is not a conservative technique, but it provides a reliable and robust reduction. Objective: This study aims to compare the symptoms as well as health-related quality of life (HQOL) in 55 patients who underwent septoplasty with concomitent medial flap inferior turbinoplasty (group 1), 53 patients who patients underwent septoplasty with concomitent coblation turbinator (group 2). Patients and methods: The authors performed a prospective, randomized study of 108 patients who consulted the otorhinolaryngology department at the university hospital for surgery of septoturbinoplasty. Results: Preoperatively, the two patient groups had quite similar symptoms and health-related quality of life, and the anterior width of the inferior turbinate showed significant differences between the contralateral and deviated sides but not the posterior part. The significant difference (P<0.05) was noted for postoperatively improved symptom scores on visual analogue scale (VAS), nasal obstruction septoplasty effectiveness (NOSE) and better HQOL [Sino-Nasal Outcome Test-22 (SNOT-22)] in all patient groups. In addition, the NOSE and SNOT-22 scores in group 2 had significantly greater improvement than group 1 (P<0.05). Conclusions: Septoturbinoplasty treatment of septum deviation and inferior turbinate hypertrophy led to less symptoms as well as better HQOL for all two patient groups. Therefore, these techniques were an effective intervention for turbinate reduction, and they are equally efficient in the long term.
RESUMO
African swine fever (ASF) is a devastating disease affecting the global swine industry. Recently, it has spread to many countries in Africa, Europe, Asia, and the Caribbean, leaving severe damage to local, regional, national, and global economies. Due to its highly complex molecular characteristics and pathogenesis, the development of a successful vaccine has been an unmet challenge. Therefore, ASF control relies solely on biosecurity, rapid detection, and elimination. Epidemiological information obtained from natural ASF outbreaks is critical for designing and implementing ASF control measures. Basic reproduction number (R0), an epidemiological metric used to describe the contagiousness or transmissibility of infectious agents, is an important epidemiological tool. In this study, we have calculated R0 for the in-farm spread of ASF among fattening pigs and sows in two midsize commercial pig farms, HY1 and HY2, that practice the spot removal approach in controlling ASF outbreaks in Vietnam. The R0 values for the sows and fattening pigs were 1.78 (1.35-2.35) and 4.76 (4.18-5.38) for HY1 and 1.55 (1.08-2.18) and 3.8 (3.33-4.28) for HY2. This is the first study to evaluate the transmission potential of ASF in midsize commercial pig farms in Vietnam. Based on the R0 values, we predict that the spot removal approach could be used to successfully control ASF outbreaks in midsize commercial sow barns but not in fattening pens.
