Culture results of external auditory canal in hemodialysis patients with hearing aid

Hemodialysis treatment of chronic renal failure patients may face many complications. Dialysis treatment may increase the risk of infection of the patient and also affect other organs. Especially for individuals who use hearing aids, the defense mechanism of the external ear canal is disrupted and is preparing the ground for ear infections. As a result, both the external auditory canal and ear mold colonizing bacteria and fungi. The purpose of study, microbiological results of the external auditory canal in hemodialysis patients with hearing aids, to investigate the cause of the irritation properties and to compare with the normal population. Our study is a descriptive clinical study and has control group. In addition patients were taken from the Baskent University Otorhinolaryngology Head and Surgery Department, Baskent University Dialysis Centers. At least 1 year uses in one or both ears hearing aid, with at least 2 years and have been included in hemodialysis patients in the 15-85 age range. Discrimination between men and women are not respected. A total of 74 patients were icluded in the study. The individuals in the study group were 20, were kept in sterile swabs from hearing aids of hemodialysis patients with 2 samples were taken. One device used in the external ear canal, the ear mold is the second device. In the same age group as the control group and 27 subjects who were only treated hemodialysis patients and but it has been included in non-diaylsis patients 27 individuals hearing aid (at least one year) in the study. Bacterial growth of swab samples taken was used sheep blood agar, EMB agar and Chocolate agar. The samples for fungal growth were sown on Sabouraud dextrose agar. Samples were incubated for 24-48 hours in 37 ⁰C temperature. The results compared between the groups. Examined 108 (%89.2) of 121 total culture samples have been breeding. 20 dialysis patients who using hearing aid in the study group (Group 1) all of their external ear and ear molds (%100) has been breeding. It is available in 40 culture samples in the study group showed that patients with multiple microorganisms proliferated. A total of 54 microorganisms were isolated. Using the hearing aid 27 hemodialysis patients (Group 2) only 2 (%7,4) patients were not breeding. Using hearing aid without 27 hemodialysis patients (Group 3) 11 (%40,7) there has been no growth in them. Also common to all three groups, and isolated in the normal skin flora methicillin-sensitive CNS (MSCNS). The breeding of organisms in the study group were significantly more than the control group. Unlike the other groups, Corynebacterium species, Pseudomonas spp and fungus was observed in this group. In all groups isolated organism was MSCNS. Pseudomonas spp and Staphyloccocus aureus as pathogenic bacteria have been less isolated from external ear canal and hearing aid. In only hemodialysis patient pseudomonas spp, corynebacterium species and fungus had grown that using hearing aid.
