We present a review of current knowledge about mucosal leishmaniasis (ML). Although involvement of mucous membranes is classically admitted in New World leishmaniasis, particularly occurring in infection by Leishmania (L.) braziliensis species complex, ML is also a possible presentation of Old World leishmaniasis, in either L. donovani or L. major species(More)
In this paper, we evaluate the performance of six intrusive objective measures as intelligibility predictors of degraded speech for cochlear implant (CI) users. Three practical environmental degradation scenarios are considered: reverberation alone, additive noise alone, and noise-plus-reverberation. A subjective intelligibility test was performed with(More)
This study validates a novel approach to predict speech intelligibility for Cochlear Implant users (CIs) in rever-berant environments. More specifically, we explore the use of existing objective quality and intelligibility met-rics, applied directly to vocoded speech degraded by room reverberation, here assessed at ten different reverberation time (RT60)(More)
We describe a case of isolated primary laryngeal leishmaniasis in an immunocompetent Italian patient with a previous medical history negative for visceral or cutaneous leishmaniasis, presenting with hoarseness. We also summarize the epidemiological, clinical, and diagnostic features and the therapeutic management of other cases of laryngeal leishmaniasis in(More)
A non-intrusive objective speech quality and intelligibil-ity measure tailored to hearing restoration instruments is proposed and evaluated in complex listening environments. The measure builds upon the previously-proposed " speech-to-reverberation modulation energy ratio " (SRMR) by incorporating hearing impairment percepts, such as hearing loss thresholds(More)
OBJECTIVE Electrically evoked compound action potentials (ECAPs) have been employed as a measure of neural activation evoked by cochlear implant (CI) stimulation. A forward-masking procedure is commonly used to reduce stimulus artefacts. This method estimates the joint neural activation produced by two electrodes-one acting as probe and the other as masker;(More)
Cochlear implant (CI) users have poor temporal pitch perception, as revealed by two key outcomes of rate discrimination tests: (i) rate discrimination thresholds (RDTs) are typically larger than the corresponding frequency difference limen for pure tones in normal hearing listeners, and (ii) above a few hundred pulses per second (i.e. the "upper limit" of(More)
Behavioral measures of spatial selectivity in cochlear implants are important both for guiding the programing of individual users' implants and for the evaluation of different stimulation methods. However, the methods used are subject to a number of confounding factors that can contaminate estimates of spatial selectivity. These factors include off-site(More)
A model is presented that predicts the binaural advantage to speech intelligibility by analyzing the right and left recordings at the two ears containing mixed target and interferer signals. This auditory-inspired model implements an equalization-cancellation stage to predict the binaural unmasking (BU) component, in conjunction with a modulation-frequency(More)
