Speech therapy for compensatory articulations and velopharyngeal function: a case report

The objective of this study was to describe the process of intensive speech therapy for a 6-year-old child using compensatory articulations while presenting with velopharyngeal insufficiency (VPI) and a history of cleft lip and palate. The correction of VPI was temporarily done with a pharyngeal obturator since the child presented with very little movement of the pharyngeal walls during speech, compromising the outcome of a possible pharyngeal flap procedure (pharyngoplasty). The program of intensive speech therapy involved 3 phases, each for duration of 2 weeks incorporating 2 daily sessions of 50 minutes of therapy. A total of 60 sessions of intervention were done with the initial goal of eliminating the use of compensatory articulations. Evaluation before the program indicated the use of co-productions (coarticulations) of voiceless plosive and fricative sounds with glottal stops (simultaneous production of 2 places of productions), along with weak intraoral pressure and hypernasality, all compromising speech intelligibility. To address place of articulation, strategies to increase intraoral air pressure were used along with visual, auditory and tactile feedback, emphasizing the therapy target and the air pressure and airflow during plosive and fricative sound productions. After the first two phases of the program, oral place of articulation of the targets were achieved consistently. During the third phase, velopharyngeal closure during speech was systematically addressed using a bulb reduction program with the objective of achieving velopharyngeal closure during speech consistently. After the intensive speech therapy program involving the use of a pharyngeal obturator, we observed absence of hypernasality and compensatory articulation with improved speech intelligibility

Uncharted waters: rare and unclassified cardiomyopathies characterized on cardiac magnetic resonance imaging

Cardiac magnetic resonance imaging (CMR) has undergone considerable technology advances in recent years, so that it is now entering into mainstream cardiac imaging practice. In particular, CMR is proving to be a valuable imaging tool in the detection, morphological assessment and functional assessment of cardiomyopathies. Although our understanding of this broad group of heart disorders continues to expand, it is an evolving group of entities, with the rarer cardiomyopathies remaining poorly understood or even unclassified. In this review, we describe the clinical and pathophysiological aspects of several of the rare/unclassified cardiomyopathies and their appearance on CMR

Remote ischaemic pre-conditioning does not attenuate ischaemic left ventricular dysfunction in humans.

AIMS: Remote ischaemic pre-conditioning (RIPC) reduces distant tissue ischaemia reperfusion injury. We tested the hypothesis that RIPC would protect the left ventricle (LV) from ischaemic dysfunction and stunning. METHODS AND RESULTS: Forty-two patients with single vessel coronary disease and normal LV function were prospectively recruited. Twenty patients had repeated conductance catheter assessment of LV function during serial coronary occlusions with/without RIPC and a further 22 patients underwent serial dobutamine stress echocardiography and tissue Doppler analysis with/without RIPC. Remote ischaemic pre-conditioning was induced by three 5 min inflations of a blood pressure cuff around the upper arm. RIPC did not diminish the degree of ischaemic LV dysfunction during coronary balloon occlusion (Tau, ms: 59.2 (2.8) vs. 62.8 (2.8), P = 0.15) and there was evidence of cumulative LV dysfunction despite RIPC [ejection fraction (EF), %: 54.3 (5.8) vs. 44.9 (3.7), P = 0.03]. Remote ischaemic pre-conditioning did not improve contractile recovery during reperfusion (EF, %: 51.7 (3.6) vs. 51.5 (5.7), P = 0.88 and Tau, ms: 55.6 (2.8) vs. 56.0 (2.0), P = 0.85). A neutral effect of RIPC on LV function was confirmed by tissue Doppler analysis of ischaemic segments at peak dobutamine (V(s), cm s(-1) control: 8.2 (0.4) vs. RIPC 8.1 (0.4), P = 0.43) and in recovery. CONCLUSION: RIPC does not attenuate ischaemic LV dysfunction in humans

Remote ischemic preconditioning reduces myocardial and renal injury after elective abdominal aortic aneurysm repair: a randomized controlled trial.

BACKGROUND: Myocardial and renal injury commonly contribute to perioperative morbidity and mortality after abdominal aortic aneurysm repair. Remote ischemic preconditioning (RIPC) is a phenomenon whereby brief periods of ischemia followed by reperfusion in one organ provide systemic protection from prolonged ischemia. To investigate whether remote preconditioning reduces the incidence of myocardial and renal injury in patients undergoing elective open abdominal aortic aneurysm repair, we performed a randomized trial. METHOD AND RESULTS; Eighty-two patients were randomized to abdominal aortic aneurysm repair with RIPC or conventional abdominal aortic aneurysm repair (control). Two cycles of intermittent crossclamping of the common iliac artery with 10 minutes ischemia followed by 10 minutes reperfusion served as the RIPC stimulus. Myocardial injury was assessed by cardiac troponin I (>0.40 ng/mL), myocardial infarction by the American College of Cardiology/American Heart Association definition and renal injury by serum creatinine (>177 micromol/L) according to American Heart Association guidelines for risk stratification in major vascular surgery. The groups were well matched for baseline characteristics. RIPC reduced the incidence of myocardial injury by 27% (39% versus 12% [95% CI: 8.8% to 45%]; P=0.005), myocardial infarction by 22% (27% versus 5% [95% CI: 7.3% to 38%]; P=0.006), and renal impairment by 23% (30% versus 7%; [95% CI: 6.4 to 39]; P=0.009). Multivariable analysis revealed the protective effect of RIPC on myocardial injury (OR: 0.22, 95% CI: 0.07 to 0.67; P=0.008), myocardial infarction (OR: 0.18, 95% CI: 0.04 to 0.75; P=0.006) and renal impairment were independent of other covariables. CONCLUSIONS: In patients undergoing elective open abdominal aortic aneurysm repair, RIPC reduces the incidence of postoperative myocardial injury, myocardial infarction, and renal impairment
