Abstract
Although adenotonsillectomy is the recommended treatment of obstructive sleep apnea (OSA) in children, some patients with preoperative severe OSA (Apnea-hypopnea index/AHI > 10) remain symptomatic after surgery and may need further workup. This study aims to: (1) analyse preoperative factors and its relation with surgical failure/persistent OSA (AHI > 5 after adenotonsillectomy) in severe pediatric OSA; (2) determine the levels of airway collapse during DISE (drug induced sleep endoscopy) in cases of surgical failure; (3) evaluate the efficacy of targeted surgery based on DISE findings. This retrospective study was conducted between August and September 2020. Across 9 years (from 2011 to 2020), all children diagnosed with severe OSA in our Hospital underwent adenotonsillectomy and repeated type 1 polysomnography (PSG) 3 months after surgery. Cases of surgical failure underwent DISE for planning eventual directed surgery. Chi-square test was used to assess the relationship between persistent OSA and preoperative patients' characteristics. 80 cases of severe pediatric OSA were diagnosed (68.8% males; mean age: 4.3 years-standard deviation: 2.49; mean AHI: 16.3-standard deviation 7.14) in the aforementioned period. We found a significant association between surgical failure (11.3% of cases; mean AHI: 6.9-SD 0.91) and obesity (p = 0.002; confidence level of 95%). Neither preoperative AHI nor other PSG parameters were associated with surgical failure. In cases of surgical failure, epiglottis collapse was present in every DISEs and adenoid tissue was present in 66% of children. All cases of surgical failure had directed surgery and surgical cure (AHI ≤ 5) was obtained in 100% of cases. This study suggests that obesity is the strongest predictor of surgical failure in children with severe OSA who undergo adenotonsillectomy. Epiglottis collapse and presence of adenoid tissue are the most common findings in postoperative DISEs of children with persistent OSA after primary surgery. DISE based surgery seems a safe and effective tool to manage persistent OSA after adenotonsillectomy.

Abstract
Spondyloarthritis (SpA) is an umbrella term describing a family of chronic inflammatory rheumatic diseases. These diseases are characterised by inflammation of the axial skeleton, peripheral joints, and entheseal insertion sites throughout the body which can lead to structural joint damage including formation of axial syndesmophytes and peripheral osteophytes. Genetic evidence, preclinical and clinical studies indicate a clear role of interleukin (IL)- 23 and IL-17 as mediators in SpA pathogenesis. Targeting the IL-23/-17 pathways seems an efficient strategy for treatment of SpA patients, and despite the remaining challenges the pathway holds great promise for further advances and improved therapeutic opportunities. Much research is focusing on serological markers and imaging strategies to correctly diagnose patients in the early stages of SpA. Biomarkers may facilitate personalised medicine tailored to each patient's specific disease to optimise treatment efficacy and to monitor therapeutic response. This narrative review focuses on the IL-17 pathway in SpA-related diseases with emphasis on its role in pathogenesis, current approved IL-17 inhibitors, and the need for biomarkers reflecting core disease pathways for early diagnosis and measurement of disease activity, prognosis, and response to therapy.
