Comparison of esophageal motility in patients with solid dysphagia and mixed dysphagia.

It is unclear whether there is any difference in esophageal motor abnormalities between patients complaining of dysphagia for solids or both solids and liquids. The aim of this study was to determine any difference in the manometric findings between patients with dysphagia for solids and those with mixed dysphagia. Manometric tracings were performed in 200 consecutive patients (66 M, 134 F; mean age = 51 years) with nonobstructive dysphagia. Ambulatory pH studies were performed in all patients. Subjects were divided into two groups: patients with solid dysphagia (n = 94, 33 M, 61 F; mean age = 51 years) and those with mixed dysphagia (n = 106, 33 M, 73 F; mean age = 51 years). A normal motility study was the most frequent finding. Achalasia occurred more frequently in patients with mixed dysphagia than in those with solid dysphagia (12% vs. 3%, p < 0.01). Gastroesophageal reflux disease (GERD) was observed in 59% of patients with solid dysphagia compared with 29% of patients with mixed dysphagia (p < 0.02). The most common esophageal motility abnormality is nonspecific esophageal motility disorders. This study has shown that abnormal esophageal motility occurs slightly more in mixed dysphagia than solid dysphagia. The clinical utility of a symptomatic differentiation of patients with solid or mixed dysphagia appears to be limited.

Oropharyngeal dysphagia in amyotrophic lateral sclerosis: neurological and dysphagia specific rating scales.

BACKGROUND: Oropharyngeal dysphagia is highly prevalent in amyotrophic lateral sclerosis (ALS). Patients with dysphagia and weight loss are frequently offered gastrostomy. Although the neurological basis of dysphagia in ALS is complex, there are currently no specifically validated scales for dysphagia in ALS, and the reliability of existing generic scales has not been assessed. METHODS: We undertook a prospective study of 25 patients who fulfilled the criteria for definite or probable ALS. We examined the reliability of the Dysphagia Outcome Severity Scale (DOSS) and the Aspiration-Penetration Rating Scale (APRS) and the correlation between these scales and the Norris ALS Scale and ALS Functional Rating Scale-R (ALS FRS-R). RESULTS: Using the Pearson Product-Moment Correlation, an expected high linear association between the two disease specific neurological scales was demonstrated. Both dysphagia scales were found to be reliable. Interrelationship evaluation showed a low association between Norris and ALS FRS-R scores and DOSS and APRS. However, examination found specific subsections to be significantly correlated, particularly the Norris bulbar sections (NBS) and the DOSS. CONCLUSIONS: Generic dysphagia scales are reliable indicators of dysphagia in ALS. The bulbar components of the ALS specific scales is sensitive to dysphagia. The bulbar section of the Norris scale can be utilised as an independent and reliable indicator of the severity of dysphagia in ALS. In the absence of availability of detailed swallowing assessment using videofluoroscopy, these scales, i.e., the Norris and to a lesser degree the ALS FRS-R bulbar sections, are adequate to diagnose and follow clinically significant dysphagia in ALS, and can be used as an indicator for dysphagia treatment initiation.

An EMG screening method (dysphagia limit) for evaluation of neurogenic dysphagia in childhood above 5 years old.

Oropharyngeal dysphagia is not rare in older children before the adult age, especially the patients with cerebral palsy. Non-invasive simple tests are needed for the evaluation of children with neurogenic dysphagia including the patients with cerebral palsy. So we aimed to evaluate non-invasive ways to screen for dysphagia in children and the usefulness of this almost new electrophysiologic method for the detection of dysphagia in children with cerebral palsy. Twenty-eight healthy children and 12 patients with cerebral palsy were investigated for the applicability of this method. The movement of the larynx was monitored using a simple piezoelectric wafer sensor and submental surface EMG activity was recorded by bipolar silver-chloride electrodes taped under the chin over the submental muscle complex. The onset and duration of pharyngeal swallowing was recorded from submental-suprahyoid muscles such as the mylohyoid-genitohyoid-anterior digastric complex. By this method, the maximal water volume capacity was measured in single swallows with progressively increasing water volumes, this was called 'dysphagia limit'. The healthy control children revealed to swallow the bolus at once maximally 11.2+/-0.4 and 2.5 ml in average. Dysphagia limit varied from 7 to above 20 ml water volume from age 5-16 years old. Patients with cerebral palsy had the dysphagia limit of 7.7+/-1.8 and 6.4 ml in average. The dysphagia limit was significantly reduced in patients with cerebral palsy (p<0.05). Dysphagia limit seemed to be less sensitive in demonstrating the oropharyngeal swallowing disorders in childhood period (90% in the adult dysphagic patients). But the majority of patients with cerebral palsy (58%) showed abnormality. This electrophysiologic method is completely non-invasive, devoid from any hazard and applicable to children above 5 years. It may be candidate as a screening test before selection of dysphagic children.

Prevalence of dysphagia among community-dwelling elderly individuals as estimated using a questionnaire for dysphagia screening.

The objective of this cross-sectional study was to determine the prevalence of dysphagia among elderly persons living at home in a community using a questionnaire for dysphagia screening. As the reliability of the questionnaire had not yet been confirmed in an epidemiological study, it was also verified. The relationship between dysphagia and the level of daily living competence was also clarified. The subjects consisted of 1313 elderly persons 65 years and older (575 males and 738 females) living at home in a community. The questionnaire included questions concerning the individual's past history of stroke, and questions for dysphagia screening, competence scoring, and perceived ill health. The reliability of the questionnaire was confirmed after calculating the Cronbach's alpha coefficient to be 0.83. The results of a factor analysis showed that the cumulative contribution rate was 61.8%. The prevalence rate of dysphagia was 13.8%. After matching for age and sex, there were significant differences in the competence scores, history of stroke, and perceived ill health status observed between the group with dysphagia and the group without dysphagia.

Solid-state computerized manometry improves diagnostic yield in pharyngeal dysphagia: simultaneous videoradiography and manometry in dysphagia patients with normal barium swallows.

OBJECTIVE: Dynamic barium radiology with cine- or video recording has been the most frequently used technique for assessing patients with pharyngeal dysphagia. Although the diagnostic yield of the barium swallow has been high, many patients with pharyngeal dysphagia have normal dynamic barium radiology and remain a diagnostic dilemma. Could manometry add important diagnostic information in these patients? MATERIAL AND METHODS: We examined 19 patients (12 men and 7 women, mean age 47 years, range 19-69 years) with pharyngeal dysphagia but a normal barium swallow with simultaneous videoradiography and pharyngeal manometry and compared their manometry to that found in 24 normal volunteers (11 men and 13 women, mean age 37 years, range 23-59 years). RESULTS: Comparing mean values, the patient group showed statistically significant differences from the control group for eight of 10 manometric parameters. Fourteen of 19 patients showed at least one (five patients) and in most cases multiple (nine patients) manometric abnormalities (values exceeding normal mean by +/- 2SD) which might have contributed to their dysphagia: five patients with high upper esophageal sphincter (UES) resting pressures, five with high UES residual pressures, three with weak pharyngeal contractions, three with pharyngeal "spasms," seven with prolonged contraction/relaxation times, five with reduced compliance, and seven with UES/P incoordination. CONCLUSIONS: Solid-state computerized manometry is a useful adjunct to videoradiography and can provide potentially important additional information in the diagnosis of dysphagia patients.

Dysphagia complications in ankylosing spinal hyperostosis and ossification of the posterior longitudinal ligament. Roentgenographic findings of the developmental process of cervical osteophytes causing dysphagia.

This is the first report of the process of formulation of a cervical osteophyte causing dysphagia. The patient had ankylosing spinal hyperostosis and OPLL and was followed radiographically for a long time before the onset of dysphagia. The radiological observation suggested that dysphagia was produced when the immobile part of the esophagus was compressed by the anterior projecting cervical osteophyte. The immobility of the esophagus is an important factor in determining whether dysphagia occurs. Another possible contributing factor to dysphagia in this patient was the ossification of the cervical anterior and posterior longitudinal ligaments. The OPLL affected intervertebral segmental motion and induced the formation of anterior projecting cervical osteophytes.

'Dysphagia Severity Score' system: clinical outcomes in paediatric dysphagia.

Clinical evaluation and analysis of therapeutic intervention, by means of a user-friendly outcome measure system, is essential in the management of a paediatric dysphagia caseload. The objective of this study was to design a Dysphagia Severity Score (DSS) system and to evaluate its usefulness in profiling dysphagia outcomes. Clinical outcome data, based on ten clinical parameters describing dysphagic status pre- and post-intervention, were collated for 23 concurrent cases and recorded on a data base. Results indicate that all subjects scored an improvement in DSS percentage post-intervention, with an average improvement of 21%. Dysphagia Severity Score profiles are presented for two patients and the limitations and applications are discussed.

[Experience with home visits for treatment of dysphagia (Clinical meaning of severity grading of dysphagia)].

It is more difficult to adequately manage dsyphagia patients at home than in the hospital. Based on the author's experience with home visits, grading the severity of dysphagia is advocated as helpful in reducing the difficulty. Both the clinical meaning and usefulness of severity grading are discussed. A diagnostic procedure designed by the author and ENT colleagues was applied to patients complaining of dysphagia at home. The procedure consists of three components, i.e., a questionnaire chart, endoscopic survey of the throat while swallowing and an assessment of the patient's general condition. Analysis of 24 cases revealed that the severity of dysphagia could be classified into four degrees, and that the the severity was helpful for determing the protocol of subsequent treatment. The part of the management of dysphagia at home in which the ENT physician can participate has been clarified.

Identification of a simple screening tool for dysphagia in patients with stroke using factor analysis of multiple dysphagia variables.

OBJECTIVE: To identify a most useful and simple clinical screening tool to predict videofluoroscopic aspiration in patients with stroke. DESIGN: Factor analysis of multiple dysphagia variables and sensitivity and specificity testing with chi-square test. PATIENTS: Sixty-one consecutive stroke patients with symptoms suggestive of dysphagia admitted to a university hospital and its 4 affiliated hospitals in Japan. METHODS: Factors were extracted from 6 oromotor examinations (lip closure, tongue movement, palatal elevation, gag reflex, voice quality and motor speech function), 2 swallow screen tests (saliva swallowing test and our modified water swallowing test using 30 ml of water) and 4 parameters evaluated with a videofluoroscopic swallow study. Sensitivity and specificity of each dysphagia-related variable was determined against aspiration in a videofluoroscopic swallow study. RESULTS: Factor analysis revealed that cough/voice change in the water swallowing test and aspiration on videofluoroscopic swallow study belonged to the same factor. Chi-square analysis showed that cough/voice change in the water swallowing test was the only variable that was significantly associated with aspiration on videofluoroscopic swallow study, with a sensitivity of 72% (95% CI: 61-83%) and a specificity of 67% (CI: 55-79%) as a predictor of aspiration (p<0.05). CONCLUSION: We recommend our modified 30 ml water-swallowing test as a useful single task-screening tool to detect aspiration.

Postoperative dysphagia versus neurogenic dysphagia: scintigraphic assessment.

In order to differentiate the features of dysphagia that occur after supraglottic horizontal laryngectomy from those that occur during neurologic diseases, we divided 38 subjects into 3 groups and submitted them to oropharyngoesophageal scintigraphy. Group 1 (control group) included 15 healthy volunteeers; group 2 comprised 8 patients who had residual dysphagia at least 1 year after supraglottic laryngectomy; and group 3 included 15 patients with various neurologic and neuromuscular disorders. In group 1, the mean values (+/- 2 SD) of selected semiquantitative parameters were consistent with those reported in the literature for normal subjects. In group 2, oral, pharyngeal, and esophageal transit times were not significantly altered, and moderate tracheobronchial post-deglutitive aspiration was present (maximum value, 6.7%; mean value, 2.04%). The pharyngeal retention index was significantly increased (p = .0003) as compared to normal subjects in all cases (maximum value, 40%; mean value, 23%) and was associated in all cases with slight but consistent post-deglutitive aspiration. In group 3, the oral and esophageal phases were significantly prolonged and the retention indices were significantly increased. Statistical analysis documented a significant increase in oral transit time (p = .003), esophageal transit time (p = .01), oral retention index (p = .006), pharyngeal retention index (p = .0007), and esophageal retention index (p = .009) as compared to normal subjects. The swallowing pattern was also altered by 1) an early loss of the bolus from the oral cavity; 2) bolus fragmentation due to double or triple deglutition, reduced lingual propulsion, or the return of a small part of the bolus into the oral cavity during deglutition; and/or 3) double pharyngeal peaks in the activity-time curves. Tracheobronchial aspiration (maximum value, 90%; mean value, 9.70%) was present in some cases, mainly in patients affected by post-stroke dysphagia. On the basis of the obtained results and considering the low doses of radiation delivered to the patient (0.043 Gy), the limited invasiveness, and the excellent patient tolerance, scintigraphy appears to be clinically valid in the functional study of swallowing and in identifying different deglutition disorders.

The development and validation of a dysphagia-specific quality-of-life questionnaire for patients with head and neck cancer: the M. D. Anderson dysphagia inventory.

OBJECTIVE: To design a reliable and validated self-administered questionnaire whose purpose is to assess dysphagia's effects on the quality of life (QOL) of patients with head and neck cancer. DESIGN: Cross-sectional survey study. METHODS: Focus groups were convened for questionnaire development and design. The M. D. Anderson Dysphagia Inventory (MDADI) included global, emotional, functional, and physical subscales. One hundred consecutive adult patients with a neoplasm of the upper aerodigestive tract who underwent evaluation by our Speech Pathology team completed the MDADI and the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36). Speech pathologists completed the Performance Status Scale for each patient. Validity and reliability properties were calculated. Analysis of variance was used to assess how well the MDADI discriminated between groups of patients. RESULTS: The internal consistency reliability of the MDADI was calculated using the Cronbach alpha coefficient. The Cronbach alpha coefficients of the MDADI subscales ranged from 0.85 to 0.93. Test-retest reliability coefficients of the subscales ranged from 0.69 to 0.88. Spearman correlation coefficients between the MDADI subscales and the SF-36 subscales demonstrated construct validity. Patients with primary tumors of the oral cavity and oropharynx had significantly greater swallowing disability with an adverse impact on their QOL compared with patients with primary tumors of the larynx and hypopharynx (P<.001). Patients with a malignant lesion also had significantly greater disability than patients with a benign lesion (P<.001). CONCLUSIONS: The MDADI is the first validated and reliable self-administered questionnaire designed specifically for evaluating the impact of dysphagia on the QOL of patients with head and neck cancer. Standardized questionnaires that measure patients' QOL offer a means for demonstrating treatment impact and improving medical care. The development and validation of the MDADI and its use in prospective clinical trials allow for better understanding of the impact of treatment of head and neck cancer on swallowing and of swallowing difficulty on patients' QOL.

Dysphagia in cerebral palsy: a comparative study of the Exeter Dysphagia Assessment Technique and a multidisciplinary assessment.

Eighteen children with cerebral palsy in a special school, most of whom had feeding difficulties, were studied to compare the diagnostic value of the Exeter Dysphagia Assessment Technique (EDAT) with an exhaustive clinical assessment undertaken by a multidisciplinary team experienced in the diagnosis and treatment of dysphagia of neurological origin. Four feeding skills were assessed by each method independently, viz. anticipation, intraoral sensory perception, oral-motor efficiency, and pharyngeal triggering. Comparison of the two sets of results showed agreement in at least 78% of the assessed skills. The possible reasons for the few discrepancies are discussed. The noninvasive EDAT equipment was easy to use with the children, who had a range of type and severity of cerebral palsy. The test was undertaken in their familiar surroundings and took 15 to 20 min per child. Interpretation of the results showed that EDAT provided a rapid, reliable diagnostic aid which assisted in the assessment of the degree of feeding impairment within each of the four feeding skills tested.

Construction and validation of the mealtime and dysphagia questionnaire: an instrument designed to assess nursing staff reasons for noncompliance with SLP dysphagia and feeding recommendations.

The lack of compliance of nursing staff with SLP recommendations may be an important contribution to the swallowing and feeding problems of the elderly and the consequent elevated probability of aspiration pneumonia and other sequelae. There is a need to study the prevalence of noncompliance with SLP recommendations for swallowing and feeding and the reason for nursing staff noncompliance for dependent feeders. This researcher constructed and validated a 21-item instrument designed to assess the reasons for staff noncompliance with SLP recommendations using a sample of 180 nursing staffers in a nursing home. The instrument, entitled the Mealtime and Dysphagia Questionnaire (MDQ), was demonstrated to have adequate reliability and concurrent validity. In addition, analyses were conducted that suggested that RNs were less compliant than CNAs. RNs indicated that they had less knowledge and regarded feeding of patients as more of a nuisance than CNAs. The major reason for RNs' noncompliance was lack of knowledge and CNAs' noncompliance was disagreement with the SLP's recommendations. The implications for SLP and nursing practice were discussed.
