Abstract. The safety of artemether-lumefantrine in patients with acute, uncomplicated Plasmodium falciparum malaria was investigated prospectively using the auditory brainstem response (ABR) and pure-tone thresholds. Secondary outcomes included polymerase chain reaction-corrected cure rates. Patients were randomly assigned in a 3:1:1 ratio to either artemether-lumefantrine ( N = 159), atovaquone-proguanil ( N = 53), or artesunate-mefloquine ( N = 53). The null hypothesis (primary outcome), claiming that the percentage of patients with a baseline to Day-7 ABR Wave III latency increase of > 0.30 msec is ≥ 15% after administration of artemether-lumefantrine, was rejected; 2.6% of patients (95% confidence interval: 0.7-6.6) exceeded 0.30 msec, i.e., significantly below 15% ( P < 0.0001). A model-based analysis found no apparent relationship between drug exposure and ABR change. In all three groups, average improvements (2-4 dB) in pure-tone thresholds were observed, and polymerase chain reaction-corrected cure rates were > 95% to Day 42. The results support the continued safe and efficacious use of artemether-lumefantrine in uncomplicated falciparum malaria.

The cochlear implant produces economic benefits for the patient. It also produces health utilities since positive cost-utility (gain in decibels) and cost-effectiveness (gain in language discrimination) ratios were found.

Despite the high frequency, skin complications did not seem to affect quality of life or subjective audiological benefits of patients with bone-anchored hearing aids.

This paper discusses parents' narratives on cochlear implantation in Bogotá, Colombia using a qualitative approach. The main research objective was to identify how parents perceived the processes of diagnosis of their child's hearing loss, making the decision for cochlear implantation and the post-surgery period. All participants were hearing couples (n = 13) with similar socio-cultural backgrounds whose children had undergone cochlear implant surgery. Results show why cochlear implants are a very highly valued technological device with great symbolic power for parents. The study also deals with how perceptions about oral/sign language and disability, as well as social expectations for their children's lifetime opportunities, determine how the parents themselves have experienced their journey through the process of their children's cochlear implantation.
