ABSTRACT
BACKGROUND: Treatment of superficial venous reflux has been shown to improve ulcer healing time and reduce the risk of ulcer recurrence. Terminal ablation of the reflux source (TIRS) is an alternative to formal endovenous ablation or surgery which can be performed by injecting sclerosant foam into the peri-ulcer plexus of the veins. TIRS has been shown to be successful and in our experience is the option preferred by many patients, when offered as an alternative to axial ablation (AA). AIM: To determine if the proportion of ulcers healed within 6 months of endovenous treatment differs between patients undergoing AA of varicose veins or TIRS by peri-ulcer foam sclerotherapy. METHODS: AAVTIRS is an assessor-blinded randomised controlled trial. Patients will be recruited from a dedicated ulcer clinic in Roscommon University Hospital and from the vascular surgical clinics in University Hospital Galway. All patients attending the ulcer clinic will be screened for eligibility. RANDOMISATION: Random computer-generated sequence is stratified by ulcer size. Allocation will be concealed using sealed opaque envelopes. BLINDING: Assessors reviewing wounds at follow -p visits will be blinded to patient allocation. PRIMARY ENDPOINT: The proportion of ulcers healed within 6 months of enrolment. DISCUSSION: This will be the first time that TIRS has been evaluated with a properly powered randomised trial in the setting of venous ulcer management. Streamlining the management of venous ulcers has broad health economic benefits. If it is found that TIRS is superior or non-inferior to AA, then a less expensive, less invasive injection can be offered as an alternative to AA in an attempt to encourage the healing of venous ulcers. If AA is found to be superior to TIRS, then this would suggest that all patients undergoing ablation in the management of venous ulcers should have their superficial reflux fully treated, building on the evidence of the EVRA trial.

BACKGROUND: Fungal otitis externa is prevalent in tropical and sub-tropical climates; however, over the past two decades, there has been a reported increase in the prevalence of otomycosis in paediatric patients from more temperate climates. This study aimed to review the children diagnosed with otomycosis at the University Hospital Limerick with reference to frequency, causative organism, predisposing factors and management. METHODS: A retrospective review was conducted of paediatric patients from 2001 to 2015. Patients with positive fungal ear swabs and a diagnosis of otomycosis were identified. RESULTS: Ninety-three patients were positive for candida (mean age, 5.8 years), 10 patients were positive for aspergillus (mean age, 9.1 years) and 1 patient had mixed fungal infection containing both fungi. There was a positive correlation between a diagnosis of otomycosis and prior treatment with topical fluoroquinolones (r = 0.8; p < 0.01). CONCLUSION: The incidence of otomycosis has been increasing since 2001, which correlates with an increase in the use of topical fluoroquinolones. Previous studies identify aspergillus as the commonest causative fungi; however, this study found that candida was the commonest isolated fungi in the paediatric population.
