AbstractBackground:The pathogenesis of cholesteatoma remains unclear, despite several theories. Alterations in the density of mast cells positive for cluster of differentiation 117 protein (also known as CD117) can be critical to cholesteatoma formation, due to the effect on keratinocyte growth factor production. This study aimed to investigate the potential role of these mast cells in cholesteatoma pathogenesis.Methods:The number and density of mast cells positive for cluster of differentiation 117 protein were immunohistochemically analysed in 52 patients: 22 with chronic otitis media alone (group one), 25 with chronic otitis media with cholesteatoma (group two) and five controls.Results:The number of these mast cells was much higher in group two (in cholesteatoma matrix tissue) than in group one (in chronic otitis media granulation tissue) or the controls (in normal post-auricular skin). The density of these mast cells was significantly greater in group two than in group one or the controls (p < 0.05). The number and density of these mast cells was much greater in group one than in controls (p < 0.01).Conclusion:Mast cells positive for cluster of differentiation 117 protein could play a role in cholesteatoma formation. Further investigation of the role of these mast cells in cholesteatoma may suggest new ways of addressing this disorder, and may enable the development of targeted treatments.

Abstract Aims The burden of chronic otitis media continues to be high, especially in developing countries. The demand for corrective procedure of surgical myringoplasty, which is considered the gold standard for tympanic membrane perforations, is also growing. Hence, there is a need to innovate simpler alternative office procedures that could save effort, time, waiting period, and expenditure. Materials and Methods This prospective study of 84 patients with mucosal chronic otitis media was undertaken in a tertiary referral hospital. All patients underwent eustachian tube function test, diagnostic nasal endoscopy, and pure tone audiometry. The size of the perforation was assessed endoscopically. All perforations were freshened first with silver nitrate solution. Silastic pieces were placed medial and lateral to the perforation with epidermal growth factor gel in between. Patients were followed up for 3 months. Results The perforations were classified into three groups (healed, partially healed, and nonhealed) based on the treatment response at the end of the first and third follow-up months. Completely healed and partially healed perforations were considered as “success” and were found to be 79% in this study. Significant association was found between healing status and type of anesthesia. However, the disease stage, size of perforation, and the duration of procedure did not affect the healing status. Conclusion Silastic enhanced myringoplasty with epidermal growth factor is a simple, effective, and economical procedure that can become an alternative to surgical myringoplasty for chronic otitis media.

AbstractIntroductionOral mucositis is regarded by patients as one of the worst and debilitating complications of conditioning and hematopoietic cell transplantation (HCT). Prevention of mucositis is one of the priorities of supportive therapy during and after conditioning.ObjectivesThe primary objective of the study was the analysis of efficacy of keratinocyte growth factor (KGF, palifermin) used in prophylaxis of oral mucositis in patients undergoing allo-HCT. The secondary objectives of the study included the analysis of the influence of palifermin on clinical course of oral mucositis and early transplant outcomes, as well as analysis of the contraindications of palifermin in patients undergoing allo-HCT.Patients and methodsA total number of 253 allo-HCT performed between 2003 and 2018 in patients aged 0–19 years in a single center were analyzed. Overall, in 161 HCTs, palifermin was administered.ResultsPatients receiving KGF were transplanted earlier in the context of calendar year, and more often received ATG, mainly due to the higher rate of unrelated donor transplants. Allo-HCT patients who were administered palifermin had shorter time of mucositis (median: 9 vs. 13 days, p < 0.001), lower mucositis grade (median: 2° vs. 3°; p < 0.001), shorter period of total parenteral nutrition (median: 19 vs. 22 days; p = 0.018), and lower incidence of episodes of febrile neutropenia (median: 39.1% vs. 83.1%; p < 0.001).ConclusionsThe use of palifermin has decreased duration and severity of oral mucositis in children after allo-HCT. Palifermin is a safe and well-tolerated compound in children undergoing allo-HCT.
