Surgical Science (SS) , 2018, DOI: 10.4236/ss.2018.91005
Abstract: Introduction: Medical literature shows consistent data on the use of botulinum toxin for the treatment of drooling, especially in patients with neurological disorder. However, any trial evaluated the reduction of sialorrhea through laryngotracheoscopy. Objective: To evaluate the reduction of salivation and aspiration in children with cerebral palsy submitted to intraparotid injection of botulinum toxin. Methods: A prospective cohort study including 31 pediatric patients with cerebral palsy who complained of sialorrhea and were submitted to an intraparotid injection of botulinum toxin type A. It was analysed the reduction of the number of bibs and the amount of saliva in the larynx and trachea through a laryngotracheoscopic examination. Results: There was a reduction in the number of bibs from 7.35 to 4 after application of BoNT/A, with p-value < 0.001. The age of the patients did not influence on the number of bibs. 71% of the patients reduced the amount of saliva in laryngotracheoscopic examination. The number of normal exams increased from 3.2% to 38.7% and aspiration fell from 38.7% to 12.9%. Conclusion: Application of botulinum toxin type A is a good method for temporary control of salivation in children with neurological disorders.

Abstract: introduction: fibrin tissue adhesive, which has applications in several areas of medicine, can be prepared by different methods. aim: to compare fibrin tissue adhesives prepared by 3 different methods. method: in this prospective experimental laboratory study, fibrin tissue adhesives prepared by the use of plasma fibrinogen (group 1), cryoprecipitation (group 2), and precipitation by ammonium sulfate (group 3) were tested on 15 rabbits and 10 fragments of dura mater. the quality of the clots was assessed in terms of the success of the healing process, local toxicity, graft adhesion capacity, and degree of adhesion of 2 fragments of dura mater produced. results: all methods produced a clot with high adhesion and no toxicity, but tensile strength testing revealed that the glue produced from the ammonium sulfate-precipitated clot (group 3) was the strongest, requiring 39 g/cm 2 to separate the fragments as opposed to 23 g/cm 2 for group 2 and 13 g/cm 2 for group 1. conclusion: all methods produced good results as far as clot formation and non-toxicity, but ammonium sulfate precipitation produced the best tensile strength and was thus the most effective method of preparing fibrin tissue adhesive.

International Archives of Otorhinolaryngology , 2010,
Abstract: Introduction: ENT procedures are very common in the pediatric surgery and otolaryngologists have a wide range of surgical procedures, and adenotonsillectomy most performed procedure, followed by otological. The most common complication is bleeding from tonsillectomies. Despite being the most feared complication, only a minority of patients need surgical intervention to stop the bleed. Objective: To evaluate the surgical profile in hospital pediatric otolaryngology Curitiba. Method: Retrospective Study of registered surgeries. Results: A total 2020 procedures performed in the operating room in 2009, 9.26% (187) and tests were 90.74% (1833) surgeries, being 65.14% (1316) performed by the SUS,% 32.47 (656) by covenant and 2.39% (48) individuals. The gender distribution was 1106 boys and 914 girls. Adenoidectomy with or without tonsillectomy corresponded to 62.5% (1146). Of these, only 0.96% (11) underwent revision surgery center. In second place comes the otological surgery, with results of tympanostomy, with or without ventilation tube, the most prevalent. Conclusion: The otolaryngologists are able to perform various types of ENT surgical. A procedure most frequently performed in pediatric hospital in Little Prince is adenotonsillectomy, with revision rate similar to that reported in the literature. Boys are more subjected to procedures than girls. Most ENT procedures performed in this hospital in 2009 were performed by the SUS. This shows the importance of adenotonsillectomy in the daily practice of pediatric ENT, and the weight of this problem among users of SUS is great.
