Deep intracochlear injection of triamcinolone-acetonide with an inner ear catheter in patients with residual hearing
Introduction In a previous study, an inner ear catheter was used to deliver low- and high-dose steroids into the cochlea prior to cochlear implant electrode insertion. With this approach, more apical regions of the cochlea could be reached and a reduction of electrode impedances in the short term was achieved in cochlear implant recipients. Whether intracochlear application of drugs via the catheter is a safe method also for patients with residual hearing has not been investigated hitherto. The aim of the present study was therefore to investigate the effect of intracochlear triamcinolone application in cochlear implant recipients with residual hearing. Patients and methods Patients with residual hearing were administered triamcinolone-acetonide (4 mg/ml; n = 10) via an inner ear catheter just prior to insertion of a MED-EL FLEX28 electrode. Impedances were measured at defined time points (intra-operatively, post-operatively and at first fitting) and retrospectively compared with a control group (no steroid application) and low- and high-dose group. Hearing thresholds were measured preoperatively, 3 days after surgery and at first fitting by pure tone audiometry. Pre- to postoperative hearing loss was determined at first fitting and compared to results from a previous study. Results The median hearing loss after implantation (125-1,500 Hz) was 20.6 dB. Four patients (40%) showed a median hearing loss of less than 15 dB, three patients (30%) between 15 and 30 dB and three patients (30%) more than 30 dB. The median hearing loss was similar to the results obtained from our previous study showing a median hearing loss of 24 dB when using FLEX28 electrode arrays. Conclusion No difference in residual hearing loss was found when comparing application of triamcinolone-acetonide using an inner ear catheter prior to the insertion of a FLEX28 electrode array to the use of the FLEX28 electrode array without the catheter. Thus, we conclude that application of drugs to the cochlea with an inner ear catheter could be a feasible approach in patients with residual hearing
Concordance of emergency department physicians' decisions on HIV post-exposure prophylaxis with national guidelines: results from a retrospective cohort study
Background Post-exposure prophylaxis (PEP) is an effective tool to prevent infection with HIV. Patients seeking PEP after potential HIV exposure usually present to the emergency department (ED). Our study sought to determine the concordance of ED physicians' decisions on HIV-PEP with national guidelines (primary objective) and to assess the clinical relevance of drug-drug interactions (DDIs) between the HIV-PEP regimen and patients' concomitant medication (secondary objective). Methods We conducted a retrospective cohort study at the ED of Hannover Medical School, Germany. Between 1 January 2018 and 31 December 2019, 113 of 11 246 screened patients presented to the ED after potential HIV exposure and were enrolled in the study. Results The median age of the patients (82.3% male) was 30 y (IQR 25-35.5), 85.8% of potential HIV exposures were characterised as sexual and 85.0% presented within 72 h. ED physicians' decisions on HIV-PEP were concordant with national guidelines in 93.8%. No clinically relevant DDIs were detected. Conclusions ED physicians' decisions on HIV-PEP were highly concordant with national guidelines. Approximately 1% of patient presentations to the ED were related to HIV exposure; therefore, training ED physicians on HIV transmission risk assessment and indications/contraindications for HIV-PEP is paramount
