Objective To investigate the patients with postoperative skin damage around the stoma after Miles operation,take measures according to the influencing factors,and explore an effective way to reduce the incidence of skin damage around the stoma patients.Methods There were 62 cases of skin damage around the stoma in 110 cases of patients with permanent colostomy in out-patient follow-up.Each patient with skin damage occurring around the stoma were retrospectively analyzed the reasons,and the related factors that might affect Miles postoperative stoma skin damage were analyzed.Results The incidence rate of Miles postoperative skin damage around the stoma was 56.36％,through the multi-factor Logistic regression analysis,there were six related factors with the Miles postoperative skin damage around the stoma,patients' excrement stimulation,ostomy bag allergies,improper operation of the replacement of the ostomy bag,the potential skin disease,excessive scrub / rub the skin,unfamiliar with ostomy care knowledge were the influencing factors of patients with skin damage around the stoma.Conclusions Appropriate stoma care products and paste methods,detailed guiding of patients and their families about ostomy care knowledge and skills can significantly reduce the incidence rate of Miles postoperative skin damage around the stoma.

OBJECTIVE To analyze the clinical characteristics,pathogen distribution and drug sensitivity of otomycosis in Hangzhou,in order to provide assistance for standardized treatment of otomycosis. METHODS A total of 115 cases of otomycosis with intact tympanic membranes,treated at our hospital from December 2022 to February 2024,were included in the study. Ear secretions were cultured,and pathogens were identified through morphological examination and mass spectrometry detection. Antifungal susceptibility testing was performed using a fungal susceptibility plate. All patients underwent ear canal cleaning under otoendoscopy combined with local drug perfusion. RESULTS The predominant pathogen in this region was Aspergillus terreus(60.8％). The susceptibility results showed that Aspergillus terreus is sensitive to posaconazole,voriconazole and itraconazole,and exhibits varying degrees of resistance to the other six drugs. The total effective rate of treatment in the 115 included patients reached 93％. CONCLUSION The main pathogen of otomycosis in this area is Aspergillus terreus,which is sensitive to triazole antifungal agents such as posaconazole,voriconazole,and itraconazole,which can be considered as the first choice for clinical treatment.
