RESUMO
The purpose of this study was to cross-culturally validate the Swedish version of the Gugging Swallowing Screen (GUSS-S) for use in the acute phase of stroke. Further, to evaluate the inter-rater reliability between different healthcare professionals. GUSS was translated into Swedish using a forward-backward method followed by expert rating to obtain content validity. For criterion validity, the GUSS-S score was compared with Flexible Endoscopic Evaluation of Swallowing (FEES) assessed with the Penetration-Aspiration Scale (PAS) in acute stroke patients (≤ 96 h after stroke onset). Convergent validity was calculated by comparison with the Functional Oral Intake Scale (FOIS) as per the comprehensive FEES assessment, the Standardized Swallowing Assessment (SSA), and the National Institutes of Health Stroke Scale (NIHSS). To evaluate inter-rater reliability, a nurse and a speech-language pathologist (SLP) independently assessed 30 patients. In total, 80 patients (32 women, median age 77 years (range 29-93) were included, mean 1.7 ± 0.9 days after admission. With a cut-off value of 14 points, the GUSS-S identified aspiration with a sensitivity of 100% and a specificity of 73% (area under the curve: 0.87, 95% CI 0.78-0.95). Spearman rank correlation showed very strong correlation between the GUSS-S and PAS (rs=-0.718, P = < 0.001) and FOIS (rs=0.720, P = 0.001) and strong correlation between the GUSS-S and SSA (rs=0.545, P = < 0.001) and NIHSS (rs=-0.447, P = 0.001). The inter-rater agreement for GUSS-S was substantial (Kw=0.67, P = < 0.001). The results indicate that the GUSS-S is a valid and reliable tool for the assessment of dysphagia in acute stroke patients by different healthcare professionals.
RESUMO
INTRODUCTION: The aim of this study was to investigate how students perceive the benefit of participating in a teacher-organised session providing feedback on exams, termed post-exam feedback, in two dental hygienist programmes. METHODS: The study was based on interviews with 22 participants, including 18 students and 4 faculty teachers. The data were approached on the basis of thematic analysis, allowing us to generate insights on how the participants reflected on their participation in the post-exam feedback sessions and how they perceived this arrangement as learners. RESULTS: The findings from the study suggest that motivated students consider post-exam feedback to be beneficial in clearing up uncertainties and deepening their understanding of issues not fully understood during the exam, as well as supporting their further learning. Less motivated students mainly consider post-exam feedback to be relevant for students who do not pass the exams. CONCLUSIONS: Organised in a student-centred way and with attentiveness to student learning preferences, the results suggest that post-exam feedback can be valuable for enhancing assessment and supporting student learning related to exams.

PURPOSE: To establish predictive models for late objective aspiration and late patient-reported choking based on dose-volume parameters and baseline patient and treatment characteristics, for patients with head and neck cancer undergoing definitive radiotherapy (RT). The impact of electively treated volume on late aspiration was also investigated. METHODS AND MATERIAL: This prospective cohort is a subsample of 124 survivors from the ARTSCAN study. Late aspiration was identified with videofluoroscopy, at a minimum of 25months after the start of RT. Patient-reported choking was analysed at 12 and 60months post RT using the EORTC Quality of Life Module for Head and Neck Cancer 35. Univariable and multivariable analyses were performed to describe the association between clinical factors and dose-volume descriptors for organs at risk (OARs) and late dysphagia. RESULTS: Aspiration was found in 47% of the eligible patients. Mean dose to the middle pharyngeal constrictor (MPC), neck dissection post RT and age at randomisation in ARTSCAN were associated to late aspiration. Mean dose to the superior pharyngeal constrictor (SPC) and swallowing complaints at baseline were associated to patient reported choking at both time-points. CONCLUSIONS: Three separate risk groups for late aspiration, and two risk groups for late patient-reported choking were identified based on number of risk factors. The size of the electively treated volume could be used as a surrogate for individual OARs predicting late aspiration.

BACKGROUND AND AIM: Arterial calcification is often detected on ultrasound examination but its diagnostic accuracy is not well validated. The aim of this study was to determine the accuracy of carotid ultrasound B mode findings in detecting atherosclerotic calcification quantified by cone beam computed tomography (CBCT). METHODS: We analyzed 94 carotid arteries, from 88 patients (mean age 70 ± 7 years, 33% females), who underwent pre-endarterectomy ultrasound examination. Plaques with high echogenic nodules and posterior shadowing were considered calcified. After surgery, the excised plaques were examined using CBCT, from which the calcification volume (mm3) was calculated. In cases with multiple calcifications the largest calcification nodule volume was used to represent the plaque. Carotid artery calcification by the two imaging techniques was compared using conventional correlations. RESULTS: Carotid ultrasound was highly accurate in detecting the presence of calcification; with a sensitivity of 88.2%. Based on the quartile ranges of calcification volumes measured by CBCT we have divided plaque calcification into four groups: <8; 8-35; 36-70 and >70 mm3. Calcification volumes ≥8 were accurately detectable by ultrasound with a sensitivity of 96%. Of the 21 plaques with <8 mm3 calcification volume; only 13 were detected by ultrasound; resulting in a sensitivity of 62%. There was no difference in the volume of calcification between symptomatic and asymptomatic patients. CONCLUSION: Carotid ultrasound is highly accurate in detecting the presence of calcified atherosclerotic lesions of volume ≥8 mm3; but less accurate in detecting smaller volume calcified plaques. Further development of ultrasound techniques should allow better detection of early arterial calcification.

OBJECTIVE: Carotid stenoses ≥50% are associated with increased risk for stroke that can be reduced by prophylactic carotid endarterectomy (CEA). Calcifications in arteries can be detected in panoramic radiographs (PRs). In a cross-sectional study, we analyzed (1) extirpated plaques for calcification, (2) how often PRs disclosed calcified plaques, (3) how often patients with stenoses ≥50% presented calcifications in PRs, and (4) the additional value of frontal radiographs (FRs). STUDY DESIGN: Patients (n = 100) with carotid stenosis ≥50% were examined with PRs and FRs before CEA. Extirpated carotid plaques were radiographically examined (n = 101). RESULTS: It was found that 100 of 101 (99%) extirpated plaques were calcified, of which 75 of 100 (75%) were detected in PRs; 84 of 100 (84%) patients presented carotid calcifications in the PRs, in 9.5% contralateral to the stenosis ≥50%. CONCLUSIONS: Carotid calcifications are seen in PRs in 84% of patients with carotid stenosis ≥50%, independent of gender. FRs do not contribute significantly to this identification.

BACKGROUND: Directed ultrasonic screening for carotid stenosis is cost-effective in populations with > 5% prevalence of the diagnosis. Occasionally, calcifications in the area of the carotid arteries are incidentally detected on odontological panoramic radiographs. We aimed to determine if directed screening for carotid stenosis with ultrasound is indicated in individuals with such calcifications. METHODS: This was a cross-sectional study. Carotid ultrasound examinations were performed on consecutive persons, with findings of calcifications in the area of the carotid arteries on panoramic radiography that were otherwise eligible for asymptomatic carotid endarterectomy. RESULTS: Calcification in the area of the carotid arteries was seen in 176 of 1182 persons undergoing panoramic radiography. Of these, 117 fulfilled the inclusion criterion and were examined with carotid ultrasound. Eight persons (6.8%; 95% CI 2.2-11.5%) had a carotid stenosis--not significant over the 5% pre-specified threshold (p = 0.232, Binomial test). However, there was a significant sex difference (p = 0.008), as all stenoses were found in men. Among men, 12.5% (95%CI 4.2-20.8%) had carotid stenosis--significantly over the 5% pre-specified threshold (p = 0.014, Binomial test). CONCLUSIONS: The incidental finding of calcification in the area of the carotid arteries on panoramic radiographs should be followed up with carotid screening in men that are otherwise eligible for asymptomatic carotid endarterectomy. TRIAL REGISTRATION: The study was registered at http://www.clinicaltrials.gov; NCT00514644.

BACKGROUND: Swallowing disorders following treatment for oral and pharyngeal cancer are mainly considered a surgical sequel. The recent finding that radiotherapy-induced decline in intraoral sensory abilities established an incentive to elucidate any association between the degree of sensory decline and the degree of swallowing dysfunction. METHODS: Oral and pharyngeal swallowing was cineradiographically examined in 15 patients with oral or pharyngeal cancer before and after treatment. The patients were also tested for intraoral sensation, shape recognition, and hole size identification. RESULTS: Swallowing function deteriorated in 67% of the patients 6 months posttreatment, with no significant improvement after 12 months. The degree of swallowing dysfunction was statistically significantly associated with the degree of diminished intraoral sensation and shape recognition. CONCLUSION: In the quest for rehabilitation after treatment for oral and pharyngeal cancer, the impact of impaired intraoral sensation and discrimination ability on swallowing function should be taken into consideration.

BACKGROUND: Patients with unilateral oral or pharyngeal cancer often receive bilateral radiotherapy because of the potential for metastases. Because postoperative sequelae are evident on the tumor side, to date little attention has been paid to sensory alterations after radiotherapy on the healthy, nontumor side. The objective of this study was to investigate possible sensory alterations. METHODS: Intraoral sensation was tested bilaterally at standardized sites in 27 patients and 20 controls. Preoperative radiotherapy was bilateral in 19 patients and unilateral in eight patients. Patients were tested before treatment, after radiotherapy, and after surgery at 6 months and 1 year. Comparisons were performed interindividually and intraindividually and between groups. RESULTS: A delayed deterioration of sensation was revealed on the nontumor side 6 months after radiotherapy. There was no recovery 1 year after treatment. CONCLUSIONS: Intraoral sensation cannot be evaluated directly after radiotherapy. It is plausible that sensory deterioration after radiotherapy has an impact on functional rehabilitation after tumor treatment.

OBJECTIVE: To test the hypothesis that preoperative asymptomatic pharyngeal swallowing dysfunction predisposes for the development of symptoms of dysphagia after uvulopalatopharyngoplasty (UPPP) and uvulopalatoplasty (UPP). MATERIAL AND METHODS: A total of 42 patients who snored were scheduled to undergo UPPP (n = 20) or UPP (n = 22). UPP was performed using either a CO2 laser or a conventional steel scalpel. Preoperatively and 1 year postoperatively all patients were examined videoradiographically to assess pharyngeal swallowing function. They also completed a questionnaire pre- and postoperatively concerning their snoring problems and swallowing function as well as the outcome of surgery. RESULTS: Preoperatively, 7 (17%) patients reported dysphagia. Pharyngeal swallowing dysfunction was demonstrated in 6/7 patients with preoperative dysphagia while pharyngeal swallowing dysfunction was evident preoperatively in 18/35 non-dysphagic patients. Of the 35 patients without preoperative dysphagia, 10 (29%/) developed dysphagia after surgery. There was no significant risk of development of postoperative dysphagia for patients with compared to patients without preoperative pharyngeal swallowing dysfunction. Only one of the seven patients with preoperative dysphagia experienced worsening of the problem. A total of 93% of the patients reported a decrease in snoring and 95% reported a decrease in daytime sleepiness. CONCLUSIONS: Preoperative pharyngeal swallowing dysfunction was not proven to predict the development of dysphagia after UPPP or UPP. The surgical method did not influence the frequency of postoperatively acquired dysphagia. The results do not indicate that patients with preoperative dysphagia should be excluded from treatment with UPPP or UPP.
