- The aim of this study was to validate the Swedish version of the dysphagia-specific quality-of-life questionnaire, the M. D. Anderson Dysphagia Inventory (MDADI). Patients with oropharyngeal dysphagia due to neurologic disease (n=30) and head and neck (H&N) cancer patients with post-treatment subjective dysphagia (n=85) were compared to an age- and gender-matched nondysphagic control group (n=115). A formal forward-backward translation was performed and followed international guidelines. Validity and reliability were tested against the Short-Form 36 (SF-36) and Hospital Anxiety and Depression Scale (HADS). Internal-consistency reliability was calculated by means of Cronbach's α coefficient. Test-retest reliability was assessed by intraclass correlation (ICC). Convergent and discriminant validity were assessed by correlations between MDADI, SF-36, and HADS. Known-group validity was examined and statistically tested. Of 126 eligible patients, 115 agreed to participate (response rate=91.3%). The age of the participants ranged between 37 and 92 years. Most of the MDADI items showed good variability and only minor floor or ceiling effects in solitary items were found. The internal-consistency reliability (Cronbach's α) of the MDADI total score was 0.88 (after correction for systematic errors in the subjects' responses to two reversed questions). All estimates reached over the satisfactory >0.70 reliability standard for group-level comparison. ICC ranged between 0.83 and 0.97 in the test-retest. The mean MDADI total score was 66.9 (SD=14.7) for the H&N cancer patients, 65.0 (16.9) for the neurologic patients, and 97.5 (4.4) for the control group (P<0.001; study patients vs. controls). The MDADI was also sensitive to disease severity as measured by different food textures. The Swedish version of the MDADI showed good psychometric properties and is a valid instrument to assess dysphagia-related quality of life. It was also shown to be a reliable instrument after correction for systematic errors in the subjects' responses to two reversed questions. Its known-group validity enables the differentiation between dysphagic and nondysphagic patients for group-level research.

- Eosinophilic esophagitis (EoE) is a chronic immune/antigen-mediated disease, with dysphagia as the main symptom. The aim of this study was to survey symptoms and health-related quality of life in adult patients with EoE at least 1year after diagnosis and a 2-month course of topical corticosteroids. Forty-seven consecutive patients [79% males, mean age 49years (range 18-90years)] were evaluated using three different questionnaires at three different occasions: the Watson Dysphagia Scale (WDS), the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Oesophageal Module 18 (EORTC QLQ-OES18) and the Short Form-36 (SF-36). The median time from diagnosis to the long-term follow-up was 23months (range 12-34months). The WDS scores and the EORTC QLQ-OES18 Dysphagia and Eating scale scores were improved after 2months of treatment (p=0.00007, p=0.01, p=0.004, respectively), as were the long-term follow-up scores (p=0.01, p=0.03, p=0.005, respectively), relative to the scores at diagnosis. In addition, the EORTC QLQ-OES18 Choking scores were improved after the steroid course (p=0.003) but not after the long-term follow-up. No significant differences were detected with respect to the SF-36 scores. In summary, EoE seems to be associated with a substantial burden of symptoms that improve significantly after treatment. A partial remission persists more than 1year after diagnosis and the discontinuation of medication. The WDS and the EORTC QLQ-OES18 appear to be sensitive instruments appropriate for surveillance in these patients.
