ABSTRACT

OBJECTIVES: The purpose of this study was to assess the effectiveness and safety of xylitol nasal spray as a prophylactic treatment for children with recurrent acute otitis media (AOM). METHODS: This is a prospective pilot study of children aged 1-4 years, diagnosed with recurrent AOM (at least three episodes in the three months before recruitment) between December 1, 2019 and January 31, 2023. Children were treated with nasal xylitol spray 2-3 times daily for 3 months. The number of AOM episodes and treatments administered were compared within 3-month intervals: before recruitment, during xylitol use, and during the three subsequent months. RESULTS: Of 68 children enrolled, 66 (97%) completed the follow-up, until July 2023. Thirty-eight (58%) were males. Sixty-three children (95%) were 12-24-months old. The mean number of AOM episodes during xylitol use, 1.06 (95% confidence interval [CI]: 0.73-1.39), was lower than in the 3-month previous interval, 4.12 (95% CI: 3.89-4.40), p < 0.001; and similar to that in the subsequent 3-month interval, 0.79 (95% CI: 0.49-1.08), p = 0.082. A similar pattern was observed in an analysis of the number of AOM episodes per patient month. The data were similar during spring and summer months as during autumn and winter months. Across the consecutive three-month intervals, decreases were observed in the mean number of AOM episodes treated with systemic antibiotics (3.35, 0.65, and 0.41), p < 0.001; and with topical antibiotics (1.38, 0.55, and 0.32), p < 0.001. No major side effects were recorded. CONCLUSIONS: The findings support the effectiveness and safety of nasal xylitol spray, for preventing recurrent AOM in children aged 1-4 years.

ABSTRACT

OBJECTIVE: To examine associations of laboratory and imaging data with diagnostic parameters of necrotizing otitis externa (NOE) and its severity, and to compare between bacterial and fungal infections. METHODS: Records of patients diagnosed with NOE during 2010-2018 at the Department of Otolaryngology, Head and Neck Surgery were reviewed retrospectively for demographics; disease characteristics; and laboratory, scintigraphy, and imaging results. RESULTS: Of 48 patients with NOE, the mean age is 73±11.6 years; 32 (67%) were males; 83% had diabetes mellitus. Common pathogens were pseudomonas (49%) and fungi (33%). Sensitivities of the technetium-scan (SPECT ratio ≥1.5), temporal bone computed tomography (CT), and gallium-scan (SPECT ratio ≥1.3) were: 78.7%, 48.8%, and 31.4%, respectively. Gallium-scan results correlated positively with CT bone involvement (p=0.002) and hospital length of stay (p=0.0014). C-reactive protein (CRP) level correlated with hospital length of stay (p=0.028) and positive technetium-scan results (p=0.012). Fungal infection had a higher technetium SPECT ratio (2.16 vs. 1.77, p=0.04), gallium SPECT ratio (1.4 vs. 1.2, p=0.02), longer duration of systemic treatment (87.4 vs. 37.9 days, p=0.014), and longer hospital length of stay (31.6 vs. 15.2 days, p=0.004) compared to non-fungal infection. Eight (17%) patients had responded poorly to treatment. Fungal pathogens, facial nerve paresis, extra-auricular, and bilateral disease were more prevalent among the non-responders. CONCLUSION: The technetium scan has higher sensitivity than temporal bone CT for diagnosing NOE. The gallium scan and CRP correlated well with hospital length of stay. A high rate of fungal infection was found, with significantly higher technetium and gallium SPECT ratios and worse outcome compared to bacterial infection. Fungal NOE remains therapeutically challenging.

ABSTRACT

This retrospective case review describes a subset of 5 patients with necrotizing otitis externa (NOE) with a refractory disease course who underwent surgery as part of their management plan between 2008 and 2013. Surgery promoted the cure of 4 of the 5 patients, and a fungal pathogen was recovered in 4 of 5 surgical samples. We conclude that surgery may be a necessary diagnostic and treatment adjunct in selective cases of NOE, especially in patients with a refractory disease course or with a suspected fungal etiology.

ABSTRACT

OBJECTIVE: This study describes a subset of necrotizing otitis externa (NOE) patients with a refractory disease and negative cultures. In these cases, we decided to use a polymerase chain reaction (PCR) assay from surgically obtained tissue under sterile conditions to improve pathogen detection sensitivity. STUDY DESIGN: Retrospective case review. SETTING: Academic medical center. PATIENTS: Nineteen consecutive patients diagnosed with NOE between January 2008 and January 2014 inclusive. Three patients of this cohort presented a culture-negative disease. INTERVENTIONS: Diagnostic. MAIN OUTCOME MEASURES: Positive detection of pathogens using a PCR assay in cases with a complicated course of NOE and clinical resolution of the disease after targeted therapy according to PCR results. RESULTS: Surgical samples were obtained under sterile conditions from three patients with negative cultures and a refractory disease course of NOE. PCR assays were performed using pan-bacteria and pan-fungi protocols. In all three samples, a positive result for a fungal pathogen was recorded and followed by successful empirical targeted therapy. CONCLUSION: Patients who present with a refractory culture-negative NOE should be suspected as suffering from a fungal disease. The PCR assay may be an important laboratory adjunct in detecting pathogens responsible for NOE and can aid to promote therapy and disease resolution.
