Realization and representation of Nepali laryngeal contrasts: Voiced aspirates and laryngeal realism

In this study we push laryngeal realist theory in a new direction – to segments proposed to be specified for both [voice] and [spread] features – a combination which poses challenges to the current diagnostics. To do so, we analyze acoustic data from Nepali, an Indic (a.k.a. Indo-Aryan) language with a single class of stops described as both voiced and aspirated. We apply the same criteria and diagnostics used in laryngeal realism. We find support for the proposed representation, with a caveat that the [voice] feature appears 'stronger' than [spread].

Exploring participation experiences of youth who use AAC in social media settings: impact of an e-mentoring intervention.

Authors: Grace E, Raghavendra P, McMillan JM, Gunson JS Abstract The contribution of cross-age peer e-mentoring on reported experiences of participation during online conversations using social media was explored in this pre-experimental study. Young people (n = 4, aged 13; 4-18;3 [years; months]) who used augmentative and alternative communication (AAC) participated in an e-mentoring intervention. Two mentors who also used AAC had regular conversations with the participants via Facebook 1 , email, or Skype 2 . It was predicted that the mentoring support would contribute to experiences of participation in online conversations outside of the e-mentoring intervention. Reported experiences of participation in online conversations with communication partners other than the mentor w...

Loudness Trumps Pitch in Politeness Judgments: Evidence from Korean Deferential Speech.

Authors: Idemaru K, Winter B, Brown L, Oh GE Abstract Social meaning is not conveyed through words alone, but also through how words are produced phonetically. This paper investigates the role of loudness and pitch in determining the perception of politeness-related judgments in Korean. It has been proposed that high pitch is universally associated with polite or deferential social meanings. In contrast to this, Experiment 1 examined the perceptual effect of pitch and found no effect. Experiment 2 tested the effect of loudness, and found that listeners associate quieter speech with deference. Finally, Experiment 3 investigated the simultaneous effects of loudness and pitch, and found again that loudness had a consistent effect, whereas pitch only had a weak effect. Analyses of indi...

Assessing Gait Stability before and after Cochlear Implantation.

Authors: Kaczmarczyk K, Błażkiewicz M, Wiszomirska I, Pietrasik K, Zdrodowska A, Wit A, Barton G, Skarżyński H Abstract Background: It is known that cochlear implantation may alter the inner ear and induce vestibular disorders. Research Question: How does cochlear implantation influence gait stability? Material and Methods. An experimental group of twenty-one subjects scheduled for cochlear implantation underwent gait testing twice, on the day before cochlear implantation (BCI) and three months after cochlear implantation (ACI), using a motion capture system. A control group of 30 age-matched healthy individuals were also tested. Results: In the experimental group, the gait stability ratio (GSR) was found to improve in 17 subjects after implantation, by an average of 6%...

Robotic cochlear implantation: feasibility of a multiport approach in an ex vivo model

ConclusionsElectrode insertion through a robotic three-port approach is feasible. Drill tunnels through the facial recess for the electrode and endoscope allow for optimized insertion angles and sufficient visualization. Through a retrofacial tunnel effective manipulation for sealing is possible. (Source: European Archives of Oto-Rhino-Laryngology)

Changes in Maxillary Sinus Volume and It ’s Walls Thickness Due to Chronic Rhinosinusitis: A Prospective Study

AbstractThis is a prospective observational cross sectional study comprising of 57 patients who were having symptoms of chronic rhinosinusitis which were evaluated with the help of computed tomography scan (coronal and axial sections) to measure the thickness of all walls of maxillary sinus and it 's volume. Computed tomographic imaging of sinonasal region has become the gold standard in the evaluation of patients with chronic sinusitis. The maxillary sinus is pyramidal in shape with lateral wall of nose forming its base and its apex is directed towards zygomatic process. All three dimensio ns of the maxillary sinus were measured and the volume of each maxillary sinus was also calculated. Hyperostosis of maxillary sinus tended to increase maxillary sinus walls thickness which ultimately ...

Radiographic scoring methods in rheumatoid arthritis and psoriatic arthritis

Abstract

Structural changes of bone and cartilage are the hallmarks of rheumatoid arthritis (RA) and psoriatic arthritis (PsA). Radiography can help in making diagnosis and in differentiating PsA and RA from other articular diseases. Radiography is still considered the preferred imaging method to assess disease progression, reflecting cumulative damage over time. The presence of bone erosions in RA is as an indicator of irreversible articular damage. Radiographic features of PsA are characteristic and differ from those observed in RA, especially in the distribution of affected joints and in the presence of destructive changes and bone proliferation at the same time. Semiquantitative scoring methods are designed to measure the degree of radiographically detectable joint damage and of changes over time. Several radiographic scoring methods that had been developed originally for RA have been adopted for the use in PsA. This review discusses the use of conventional radiography for diagnosing and detecting early structural changes in RA and PsA and providing a historical overview of commonly used scoring methods.

Robotic cochlear implantation: feasibility of a multiport approach in an ex vivo model

Abstract

Purpose

A recent clinical trial has shown the feasibility of robotic cochlear implantation. The electrode was inserted through the robotically drilled tunnel and an additional access through the external auditory canal was created to provide for means of visualization and manipulation. To obviate the need for this additional access, the utilization of multiple robotically drilled tunnels targeting the round window has been proposed. The objective of this study was to assess the feasibility of electrode insertion through a robotic multiport approach.

Methods

In four ex vivo human head specimens (left side), four trajectories through the facial recess (2x) and the retrofacial and suprameatal region were planned and robotically drilled. Optimal three-port configurations were determined for each specimen by analyzing combinations of three of the four trajectories, where the three trajectories were used for the electrode, endoscopic visualization and manipulative assistance. Finally, electrode insertions were conducted through the optimal configurations.

Results

The electrodes could successfully be inserted, and the procedure sufficiently visualized through the facial recess drill tunnels in all specimens. Effective manipulative assistance for sealing the round window could be provided through the retrofacial tunnel.

Conclusions

Electrode insertion through a robotic three-port approach is feasible. Drill tunnels through the facial recess for the electrode and endoscope allow for optimized insertion angles and sufficient visualization. Through a retrofacial tunnel effective manipulation for sealing is possible.
