Clinical characteristics of dysphagic stroke patients with salivary aspiration: A STROBE-compliant retrospective study.

The aim of this study was to evaluate the correlation between radionuclide salivagram findings and clinical characteristics in stroke patient with swallowing difficulty.In this study, dysphagic stroke patients who had undergone both a radionuclide salivagram and videofluoroscopic swallowing study (VFSS) were included retrospectively. To evaluate the correlations between clinical parameters and salivary aspiration, clinical parameters, such as stroke lesion, the degree of paralysis, sex, age, onset duration of stroke, the score of the Mini-Mental State Examination (MMSE), the score of the Global Deterioration Scale (GDS), the total score of the Modified Barthel Index (MBI), and each sub-score of the MBI were collected and analyzed.In the results of this study, the MMSE score was the only significant parameter for predicting positive findings in a salivagram in a multivariate logistic regression analysis in patients with supratentorial stroke. In patients with infratentorial stroke, however, the transfer sub-score of MBI was the only significant parameter for predicting positive findings in a salivagram in a multivariate logistic regression analysis.In conclusion, care should be taken to prevent salivary aspiration when the MMSE score is less than eight in patients with supratentorial stroke, and the transfer sub-score of MBI score is less than three in patients with infratentorial stroke.

Different clinical predictors of aspiration pneumonia in dysphagic stroke patients related to stroke lesion: A STROBE-complaint retrospective study.

Although stroke is one of the most common causes of dysphagia, no studies have investigated the radionuclide salivagram as a predictor of aspiration pneumonia in patients with stroke. In addition, few researches on the risk factors of aspiration pneumonia in patients with subacute and chronic stroke undergoing rehabilitation in the rehabilitation unit have been rarely conducted. In this study, therefore, we investigated whether a radionuclide salivagram could predict aspiration pneumonia, and tried to find other clinical factors that may be helpful in predicting aspiration pneumonia in stroke patients undergoing rehabilitation in the rehabilitation department.From March 2013 and January 2018, a retrospective review of the medical records of 1182 subacute and chronic stroke patients who were admitted to rehabilitation department (South Korea) was carried out. We included 117 stroke patients with swallowing difficulties who were admitted to our rehabilitation department and satisfied our criteria retrospectively. Stroke lesion, the degree of paralysis, sex, age, onset duration, feeding methods, the Mini-Mental State Examination (MMSE), the Global Deterioration Scale (GDS), the presence of aspiration in VFSS or salivagram, the penetration-aspiration scale (PAS), and the total score of the Modified Barthel Index (MBI) were investigated by reviewing medical records.To evaluate the predictor of aspiration pneumonia for patients with stroke, multivariate logistic regression analysis with forward stepwise was performed. In the results of this study, only MMSE was significant as a clinical predictor, but not aspiration in VFSS or salivagram in multivariate analysis of supratentorial stroke patients (OR, 0.895) (95% CI, 0.830-964). In multivariate analysis of infratentorial stroke patients, combined results of salivagram and VFSS (aspiration in a salivagram or VFSS) (OR, 0.956) (95% CI, 0.919-995), and total MBI scores were significant as clinical predictors (OR, 24.882) (95% CI, 1.298-477.143).In conclusion, MMSE can be a clinical predictor of the occurrence of aspiration pneumonia in patients with supratentorial stroke. In contrast, total MBI score and combined results of a salivagram and VFSS can be clinical predictors of the occurrence of aspiration pneumonia in patients with infratentorial stroke.

Usefulness of F-18 FP-CIT PET to predict dopamine-responsive hand tremor in patients other than Parkinson's disease: Two case reports.

RATIONALE: Treating the patients with hand tremors is clinically difficult, because a wide range of disorders can result in hand tremors. Therefore, when treatment for hand tremors begins, various pharmacological options have to be considered. In clinical practice, a practical approach is to initially check hand tremor patients for signs of Parkinson's disease (PD), because patients with PD can benefit from dopamine treatment. However, only part of patients with PD tends to show a meaningful improvement in hand tremors for dopamine treatment. On the other hand, dopamine treatment may help with hand tremors of patients with other disorders, but dopamine responsiveness can't be predicted by clinical assessment alone. PATIENTS CONCERNS: Hand tremors. DIAGNOSES: Hemiplegic patients (A 78-year-old man with cerebral infarction and a 65-year-old woman with traumatic brain injury) with hemi-sided hand tremor. INTERVENTIONS: Fluorinated N-3-fluoropropyl-2ß-carbomethoxy-3ß-(4-iodophenyl) nortropane (F-18 FP-CIT) positron emission tomography (PET) and dopamine agonist. OUTCOMES: After the medication, hemi-side hand tremor dramatically improved. LESSONS: Collectively, a dysfunction of the dopaminergic nigro-striatal pathway may lead to abnormal findings of F-18 FP-CIT PET, and these abnormal findings in brain-lesion patients with hand tremor may help predict dopamine responsiveness of hand tremor. We believe that our report may be helpful in the diagnosis and treatment of hand tremor in patients with brain-lesion.

The effectiveness of 2 consecutive intra-articular polydeoxyribonucleotide injections compared with intra-articular triamcinolone for hemiplegic shoulder pain: A STROBE-complaint retrospective study.

The aim of this study was to investigate the effects of intra-articular injection of polydeoxyribonucleotide (PDRN), compared with intraarticular triamcinolone (TA) injection, in subacute stroke patients with hemiplegic shoulder pain (HSP).Participants were subacute stroke patients with HSP who had undergone 2 consecutive intra-articular injections of TA or PDRN.Numeric rating scale (NRS) and passive range of motion (PROM) of hemiplegic shoulder were evaluated until 4 weeks after 2nd injection.In the results, there were significant improvements in all PROM measures 2 weeks after the second injection, compared with pre-injection results, in both groups (P < .05). In the PDRN group, however, none of the PROM measures were significantly improved at 3 and 4 weeks after the second injection, compared with pre-injection results (P ≥ .05). When comparing pre-injection results with those at 4 weeks after the second injection, all PROM and NRS measures in the TA group were more improved than in the PDRN group, but this was not statistically significant (P ≥ .05).In conclusion, considering the systemic side effects of steroids, especially among patients with diabetes or metabolic syndrome, PDRN seems to be a worthwhile treatment option for HSP, although PDRN does not seem to have an equivalent persistence effects when compared with TA.

The Effect of Nebulized Glycopyrrolate on Posterior Drooling in Patients with Brain Injury: Two Cases of Different Brain Lesions.

Posterior drooling, which can lead to substantial respiratory morbidity, including unexplained lung diseases and recurrent pneumonia, is an important issue in the rehabilitation unit. There are various treatment options for posterior drooling, including pharmacologic therapy, oral motor or behavioral therapy, biofeedback, local glandular injection of botulinum toxin, irradiation, and surgery. Among them, nebulized glycopyrrolate has the following advantages: It is noninvasive and is relatively free of central adverse effects because it does not cross the blood-brain barrier unlike other anticholinergics. Although there has been one case report regarding the effectiveness of nebulized glycopyrrolate for drooling in a motor neuron patient, there have not been any reports on its effectiveness for posterior drooling. Herein, we report two cases (an 82-year-old male bilateral hemiplegic stroke patient and a 1-year-old female cerebral palsy infant with bilaterally spastic hemiplegia of posterior drooling treated with nebulized glycopyrrolate) and identify salivary aspiration and the effect of nebulized glycopyrrolate using radionuclide salivagram. Considering its advantages and effectiveness, nebulized glycopyrrolate should be considered as one of the reliable methods to manage posterior drooling in patients with impaired cognition or swallowing difficulties, such as severe brain injury.

The Correlation Between Clinical Characteristics and Radionuclide Salivagram Findings in Patients With Brain Lesions: A Preliminary Study.

OBJECTIVE: To evaluate the correlation between radionuclide salivagram findings and clinical characteristics in dysphagic patients with brain lesions. METHODS: The medical records of 35 dysphagic patients with brain lesions who simultaneously underwent both a videofluoroscopic swallowing study (VFSS) and radionuclide salivagram were analyzed retrospectively. The subjects were divided into two groups according to the presence of aspiration on a salivagram (group A, patients with aspiration on the salivagram; group B, patients with no aspiration on the salivagram). The differences between clinical characteristics and VFSS findings (penetration-aspiration scale [PAS]) between the two groups were analyzed. RESULTS: Eleven out of 35 patients displayed salivary aspiration on the radionuclide salivagram. There were no significant differences between the two groups according to age, sex, disease duration, PAS on VFSS and feeding methods (p≥0.05). The incidence of aspiration pneumonia was significantly higher in group A. In a multivariate logistic regression analysis with forward stepwise method, the Mini-Mental State Examination (MMSE) score was the only significant parameter in predicting positive findings in salivagrams (odds ratio=0.760; 95% confidence interval [CI], 0.625-0.923; p=0.006). The area under the receiver operating characteristic curve (AUC) of the MMSE score for positive detection in salivagrams was 0.855 (95% CI, 0.689-0.953; p<0.0001). The optimal cut-off value was 7 for the MMSE score (sensitivity 72.73%, specificity 100%). CONCLUSION: In patients with brain lesions who complain of dysphagia, the MMSE score was correlated with salivary aspiration. If patients present with a score of 7 or less on the MMSE, performing a radionuclide salivagram may helpful for early detection of patients at high risk of aspiration pneumonia induced from salivary aspiration.
