Abstract
Background The effect of topical mometasone for adenoid hypertrophy treatment is well established. Nevertheless, the influence of atopy on this treatment remains ill defined. Objective This study aims to compare the effects of topical mometasone furoate treatment on the adenoid tissue between atopic and nonatopic children. Methods Fifty-one children with obstructive respiratory complaints underwent a semistructured clinical questionnaire on nasal symptoms, prick test, and nasoendoscopy. Nasoendoscopic images were digitalized, and both adenoid and nasopharyngeal areas were measured in pixels; the relative adenoid/ nasopharyngeal area was calculated. Patients were initially treated for 40 days with nasal saline solution. In a subsequent 40-day period, topical mometasone furoate (total dose, 100 μg/day) was used. Results Topical mometasone significantly improved nasal obstruction, snoring, and apnea and also significantly reduced the adenoid tissue area related to the nasopharynx (p < 0.0001). Treatment with this glucocorticoid was not influenced by atopy, neither for symptoms nor for adenoid area. Conclusion Topical mometasone furoate significantly reduced the adenoid tissue area and led to a supplementary improvement ofnasal symptoms. This improvement was similar for atopic and nonatopic patients.

Abstract
Glucocorticoids are among the most prescribed drugs worldwide for the treatment of numerous immune and inflammatory disorders. They exert their actions by binding to the glucocorticoid receptor (GR), a member of the nuclear receptor superfamily. There are several GR isoforms resulting from alternative RNA splicing and translation initiation of the GR transcript. Additionally, these isoforms are all subject to several transcriptional, post-transcriptional, and post-translational modifications, all of which affect the protein's stability and/or function. In this review, we summarize recent knowledge on the distinct GR isoforms and the processes that generate them. We also review the importance of all known transcriptional, post-transcriptional, and post-translational modifications, including the regulation of GR by microRNAs. Moreover, we discuss the crucial role of the putative GR-bound DNA sequence as an allosteric ligand influencing GR structure and activity. Finally, we describe how the differential composition and distinct regulation at multiple levels of different GR species could account for the wide and diverse effects of glucocorticoids.
