The Dysphagia in Multiple Sclerosis Questionnaire Correlates with Fiber-Optic Endoscopic Examination for Detecting Swallowing Deficits in MS.

Multiple sclerosis (MS) refers to chronic inflammation of the central nervous system including the brain and spinal cord. Assessing for the presence of dysphagia in subjects with MS represents a challenge for neurologists in clinical practice. The aim of the present study was to verify the relationship between DYMUS scores, a patient-reported scale, and objective symptoms using the Dysphagia Outcome Severity Score (DOSS), based on fiber-optic endoscopy. Data were collected in a multicenter study. Two hundred and fifteen MS patients were enrolled, irrespective of self-reported dysphagia. DOSS revealed dysphagia in 122 subjects (56.7%). Compared with non-dysphagic subjects, the presence of dysphagia was related to more severe disability, longer disease duration, and a progressive form of the disease. A DYMUS score of 0 strongly correlated with a DOSS of 6 (sensitivity 100%) while DYMUS score of > 2 correlated with a DOSS < 7 (specificity 82%) of the self-reported scale. The DYMUS questionnaire can be a useful clinical tool for red-flagging patients who should undergo objective testing and referral to a otorhinolaryngologist.

Enhanced-MRI and ultrasound evaluation of painful shoulder in patients after stroke: a pilot study.

BACKGROUND: Epidemiological and radiological studies have previously been performed to identify the possible causes of hemiplegic shoulder pain (HSP). Many different etiologies have been postulated, though no clear correlations have emerged, and a multifactorial pathogenesis of HSP has been proposed. Recently, two MRI-based studies have described different shoulder findings as possible causes of pain in chronic stroke survivors. PURPOSE: The aim of this study was to describe the structural abnormalities of the painful shoulder in the first months after stroke by ultrasound and enhanced MRI. The secondary aims were to identify possible predisposing factors for HSP and to evaluate its impact on motor recovery. METHODS: One hundred and fifty-three first-time stroke patients, admitted to the Santa Lucia Foundation for rehabilitation, were investigated for HSP. Twenty-five stroke patients with HSP and 16 stroke patients without shoulder pain were included. An ultrasound evaluation and enhanced shoulder MRI were performed for all the patients. RESULTS: Among the shoulder abnormalities detected by both imaging studies, only capsulitis, which was detected by enhanced shoulder MRI in 88% of the HSP patients, was independently associated with pain (p < 0.001) and proven to be predictive of pain intensity as expressed by the VAS score (p < 0.003). HSP correlated with a worse global recovery (p < 0.05) as well as with male sex (p = 0.006), neglect (p = 0.02) and subluxation (p = 0.03), although none of these features were found to be independent predictors of pain. CONCLUSION: Adhesive capsulitis was found to be a possible cause of HSP. However, MRI, which is more expensive than other diagnostic tools, may be considered the gold standard tool for understanding the etiology of HSP.
