Comparing monitoring and production based approaches to the treatment of phonological assembly difficulties in aphasia

Background: Waldron, Whitworth, and Howard (2011 Waldron, H., Whitworth, A. and Howard, D. 2011. Therapy for phonological assembly difficulties: A case series. Aphasiology, 25(4): 434–455. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) replicated the auditory and monitoring therapy reported in a single case by Franklin, Buerk, and Howard (2002 Franklin, S., Buerk, F. and Howard, D. 2002. Generalised improvement in speech production for a subject with reproduction conduction aphasia. Aphasiology, 16(10/11): 1087–1114. [Taylor & Francis Online] , [Google Scholar]) with four participants with phonological assembly difficulties. No participant responded in the same way as Franklin et al.’s client MB and, notably, all improvements seen were item-specific, in contrast to MB who had shown generalised improvements in naming, repetition, and reading aloud. Waldron et al. attributed this difference to the combination of underlying impairments in their participants, in particular additional lexical deficits; it remains unknown whether Franklin et al.’s results would be replicated in someone with a more pure phonological assembly difficulty. It is also unknown whether a more direct therapy approach, targeting a reduction in the production of phonological errors, rather than improving monitoring, might also be effective with this client group.

Aims: The current study aimed to compare the effectiveness of the auditory and monitoring therapy reported by Franklin et al. (2002 Franklin, S., Buerk, F. and Howard, D. 2002. Generalised improvement in speech production for a subject with reproduction conduction aphasia. Aphasiology, 16(10/11): 1087–1114. [Taylor & Francis Online] , [Google Scholar]) with a production-focused therapy based on the articulatory kinematic treatment of apraxia of speech (AOS), in a single participant with phonological assembly difficulties.

Methods & Procedures: Participant RE received three consecutive therapy phases: Franklin et al.’s auditory therapy, followed by a new production therapy involving a hierarchy of articulatory kinematic cues and the production of minimal contrast pairs, and finally Franklin et al.’s monitoring therapy. As RE's linguistic profile was similar to that of Franklin et al.’s client, it was predicted that he would make similar gains, i.e., generalised improvement in the production of treated and untreated words, following all three therapy types.

Outcomes & Results: RE's naming of treated items improved significantly after both the production therapy and the monitoring therapy, but naming of untreated items did not improve and there were no naming improvements following the auditory therapy.

Conclusions: Two possible reasons why RE did not respond as predicted are discussed. First, that RE may have had additional lexical retrieval difficulties, in which case therapy could have improved the link between semantics and lexical phonology; and second, that RE may have had additional mild AOS, in which case therapy may have resulted in improved motor planning abilities. Neither of these hypotheses could fully account for all of RE's results. Nonetheless, the production therapy was shown to be an effective alternative approach for clients with phonological assembly difficulties, when a direct focus on speech production is needed.     

Bouveret's syndrome--a rare presentation of gallstone ileus

We present the case of an elderly Irish male with Bouveret's syndrome--a very unusual cause of gallstone ileus, where a large gallstone occludes the gastric outlet or duodenum causing obstruction. Management of this condition is often controversial. We discuss the various medical, radiological and surgical therapies available for treatment of this rare entity.

The Impact of Traumatic Experiences on Risky Sexual Behaviors in Black and White Young Adult Women

Background

Trauma exposure has been linked to risky sexual behavior (RSB), but few studies have examined the impact of distinct trauma types on RSB in one model or how the association with trauma and RSB may differ across race.

Considerations for head and neck oncology practices during the coronavirus disease 2019 (COVID‐19) pandemic: Wuhan and Toronto experience

The practices of head and neck surgical oncologists must evolve to meet the unprecedented needs placed on our health care system by the Coronavirus disease 2019 (COVID‐19) pandemic. Guidelines are emerging to help guide the provision of head and neck cancer care, though in practice, it can be challenging to operationalize such recommendations. Head and neck surgeons at Wuhan University faced significant challenges in providing care for their patients. Similar challenges were faced by the University of Toronto during the severe acute respiratory syndrome (SARS) pandemic in 2003. Herein, we outline our combined experience and key practical considerations for maintaining an oncology service in the midst of a pandemic.     

Evidence for motor neuropathy and reduced filling of the rectum in chronic intractable constipation.

Subtotal colectomy with ileorectal anastomosis is now frequently offered to patients with slow transit constipation who have severe symptoms and no response to more conventional medical treatment. If this operation is to be successful, the underlying problem should be delay in the progress of contents through the colon but no mechanical or functional obstruction in the small bowel or rectum. We have used a recently described technique of prolonged ambulant manometry and electromyography to investigate anorectal function in these patients. Pressure data were collected using a 2 mm diameter intrarectal probe carrying microtransducers, and external anal sphincter activity was assessed by a pair of silver-silver chloride surface electrodes. Fourteen control subjects and eight patients with colonic inertia were studied. Sampling reflexes, indicative of rectal filling, occurred at mean (SEM) rates of 7.4 (2.0)/hour in controls but were significantly reduced in patients (2.4 (0.3)/hour (p less than 0.01]. Recurrent rectal motor complexes were seen to occur in both groups at intervals of 76 (1.8) minutes in controls and 64.9 (7.2) minutes in patients (p less than 0.1), and with amplitudes of 42.4 (2.1) mmHg and 9.2 (0.7) mmHg (p less than 0.001), respectively. External sphincter electromyographic spike activity did not differ between groups. Our results support the concept of reduced transit of faeces to the rectum from the colon over a 24 hour period in slow transit constipation and suggest that a motor neuropathy may also be present in the rectum.
