Variant of the Technique for Laryngeal Microsurgery in Cases of Difficult Laryngoscopy

Abstract Introduction Low exposure of the larynx can make laryngeal microsurgery difficult or even impossible. The application of rigid and contact endoscopy enabled oblique and retrograde angled visualization, allowing transoperative staging with greater reach of the anatomical areas. However, there is difficulty or even impossibility of performing the surgical act, due to the incompatibility of the angled path with the straight surgical tools. Objective To demonstrate the efficiency of the variant of the technique for laryngeal microsurgery in cases of difficult laryngoscopy and to analyze the new surgical instruments specific to the endoscopic procedure. Methods This is a cross-sectional retrospective study, based on the analysis of 30 medical records of patients treated surgically at a philanthropic hospital in the state of Sergipe, Brazil, between the years of 2014 and 2015. Results The technical variant used 30- and 70-degree endoscopes that provided complete oblique view of the endolarynx. The association of angled instruments (forceps, suction pumps, retractors and scissors) enabled the execution of the surgical procedures. Conclusion The association of rigid endoscopy with angled instruments promoted full visualization of the surgical lesion and operative resolution. (AU)

Adenotonsillar Hypertrophy in Pre-School Children with Sickle Cell Disease and Diagnostic Accuracy of the Sleep Disturbance Scale for Children

Abstract Introduction Adenotonsillar hypertrophy is more common in children with sickle cell disease, and can lead to sleep-disordered breathing. Objectives To determine the frequency of adenotonsillar hypertrophy in pre-school children with sickle cell disease and assess the diagnostic accuracy of the sleepdisordered breathing subscale in the Sleep Disturbance Scale for Children. Method Observational study with a group of 48 children with sickle cell disease and a control group of 35 children without the disease. The children underwent oropharingoscopy and video nasal endoscopy. The parents and/or guardians answered the questions of the subscale. Results Adenotonsillar hypertrophy was observed in 25% of the children in the study group, and in 20% of the children in the control group, with no statistical difference between the groups. The subscale score ranged from 3 to 11 in both groups. There was a statistical significance in the study group. The average was 4.79 (standard deviation [SD] ± 2.50), with 4.19 (SD ± 1.72) among the children without adenotonsillar hypertrophy, and 6.5 (SD ± 3.40) among the children with adenotonsillar hypertrophy. There was also a statistical significance in the control group. The average was 5.23 (SD ± 2.81), with 4.44 (SD ± 2.2) among the children without adenotonsillar hypertrophy, and 7.87 (SD ± 2.89) among the children with adenotonsillar hypertrophy. Conclusion Adenotonsillar hypertrophy was not associated with sickle cell disease in pre-school children. The subscale of sleep-disordered breathing in the Sleep Disturbance Scale for Children was a useful tool for the diagnostic suspicion of adenotonsillar hypertrophy in children in this age group.

Comparison of two otologic suspensions of ciprofloxacin 2 mg/mL and hydrocortisone 10 mg/mL in the treatment of otitis externa: a multicenter, double-blind, randomized study / Comparação de duas suspensões otológicas de ciprofloxacino 2 mg/mL e hidrocortisona 10 mg/mL no tratamento da otite externa: um estudo multicêntrico, duplo-cego e randomizado

This was Phase III multicenter, double-blind, randomized, comparative safety and efficacy study in parallel groups of subjects, assessing non-inferiority between two commercially available otologic suspensions containing ciprofloxacin 2mg/mL and hydrocortisone 10mg/mL (Otociriax and Cipro HC®) in the treatment of acute diffuse otitis externa. Following screening and informed consent, subjects were randomly allocated into two treatment groups: Group A (treated with Otociriax) and Group B (treated with Cipro HC®). Treatment regimen in both groups was three drops, twice daily for seven days. The primary study endpoint was otitis cure, defined as elimination of pain, edema, and otorrhea. The secondary study endpoint was presence of side effects. Efficacy assessments included presence and intensity of otitis externa manifestations. Safety assessments included vital signs and physical examination, as well as adverse event monitoring. Study data analysis was performed using GraphPad Prism 5.0...

Complicações intracranianas decorrentes de infecções otorrinolaringológicas / Intracranial complications of otorhinological infections

Apesar da redução na incidência de complicações intracranianas decorrentes de infecções otorrinolaringológicas após o advento de antibioticoterapia, estas permanecem como afecções extremamente graves. Os autores fazem uma revisão das complicãções intracranianas, com efeito expansivo, decorrentes de infecções nasossinusais e otológicas. Conclui-se que as complicações intracranianas originárias de infecções otorrinolaringológicas são graves, com alta taxa de mortalidade e sequelas.
