RESUMO
Speakers with motor speech disorders (MSD) present challenges in speech production, one of them being the difficulty to adapt their speech to different modes. However, it is unclear whether different types of MSD are similarly affected when it comes to adapting their speech to various communication contexts. This study investigates the encoding of speech modes in individuals with AoS following focal brain damage and in individuals with hypokinetic dysarthria (HD) secondary to Parkinson's disease. Participants with mild-to-moderate MSD and their age-matched controls performed a delayed production task of pseudo-words in two speech modes: normal and whispered speech. While overall accuracy did not differ significantly across speech modes, participants with AoS exhibited longer response latencies for whispered speech, reflecting difficulties in the initiation of utterances requiring an unvoiced production. In contrast, participants with HD showed faster response latencies for whispered speech, indicating that this speech mode is easier to encode/control for this population. Acoustic durations followed these same trends, with participants with AoS showing greater lengthening for whispered speech as compared to controls and to participants with HD, while participants with HD exhibited milder lengthening. Contrary to the predictions of speech production models, suggesting that speech mode changes might be particularly difficult in dysarthria, the present results suggest that speech mode adaptation rather seems particularly costly for participants with AoS.

Spondylopathy is a relatively common finding in advanced ankylosing spondylitis (AS). However non-infectious spondylodiscitis as an early manifestation of AS seems to be exceptional. In this article, we present such a case in an adolescent.

The hand x-rays of group of patients with generalised osteoarthrosis alone were compared with those patients with generalised osteoarthrosis and chondrocalcinosis (CC). An arthropathy seemingly specific for CC could be identified in the metacarpophalangeal (MCP) and carpal joints. In the MCP joints it was characterised by subchondral rarefactions, deviation of the joint axis, joint space narrowing, and osteophytosis. Usually only the second and/or third MCP joints are affected. In the carpal joints similar subchondral cysts, sometimes associated with joint space narrowing, were found much more frequently in the group with CC. There was no direct relation with the presence of calcification.
