Clinical Practice Guidelines for Oropharyngeal Dysphagia / 대한연하장애학회지

Objective@#Dysphagia is a common clinical condition characterized by difficulty in swallowing. It is sub-classified into oropharyngeal dysphagia, which refers to problems in the mouth and pharynx, and esophageal dysphagia, which refers to problems in the esophageal body and esophagogastric junction. Dysphagia can have a significant negative impact one’s physical health and quality of life as its severity increases. Therefore, proper assessment and management of dysphagia are critical for improving swallowing function and preventing complications. Thus a guideline was developed to provide evidence-based recommendations for assessment and management in patients with dysphagia. @*Methods@#Nineteen key questions on dysphagia were developed. These questions dealt with various aspects of problems related to dysphagia, including assessment, management, and complications. A literature search for relevant articles was conducted using Pubmed, Embase, the Cochrane Library, and one domestic database of KoreaMed, until April 2021. The level of evidence and recommendation grade were established according to the Grading of Recommendation Assessment, Development and Evaluation methodology. @*Results@#Early screening and assessment of videofluoroscopic swallowing were recommended for assessing the presence of dysphagia. Therapeutic methods, such as tongue and pharyngeal muscle strengthening exercises and neuromuscular electrical stimulation with swallowing therapy, were effective in improving swallowing function and quality of life in patients with dysphagia. Nutritional intervention and an oral care program were also recommended. @*Conclusion@#This guideline presents recommendations for the assessment and management of patients with oropharyngeal dysphagia, including rehabilitative strategies.

Physical activity of Korean cancer survivors is associated with age and sex

Background/Aims@#This study aimed to assess adherence to physical activity guidelines in cancer survivors and to investigate related factors. @*Methods@#The cross-sectional data of 39,845 community-dwelling participants aged ≥ 20 years (1,254 cancer survivors) in the Korea National Health and Nutrition Examination Survey were analyzed. The age- and sex-stratified prevalence for meeting exercise guidelines was obtained. The correlates of meeting exercise recommendations were evaluated by using complex-sample logistic regression models. @*Results@#Overall, 36.2% and 20.5% of cancer survivors met the recommendations for aerobic and resistance exercises, respectively. Cancer survivors and noncancer controls had similar low adherence to exercise recommendations in most age and sex groups, except young female cancer survivors (20 to 49 years old) who showed higher engagement in aerobic exercise than female noncancer controls in the same age group. Old cancer survivors (≥ 65 years) were less likely to engage in recommended levels of aerobic exercise than young cancer survivors (odds ratio [OR], 0.44; 95% confidence interval [CI], 0.24 to 0.79). Female cancer survivors were less likely to meet resistance exercise guidelines than male cancer survivors (OR, 0.32; 95% CI, 0.21 to 0.50). In addition, cancer survivors with current smoking status and cardiovascular disease were less likely to meet aerobic exercise recommendations. @*Conclusions@#The prevalence of meeting exercise guidelines are low in Korean cancer survivors and varied by age and sex. Old age is associated with an insufficient level of aerobic exercise, and female sex is associated with low participation in resistance exercise.

Dysphagia as the Only Manifestation of Myasthenia Gravis: A Case Report / 대한연하장애학회지

Dysphagia is a common manifestation of myasthenia gravis (MG), but it has been rarely reported as the only symptom. We report a 46-year-old man who complained of dysphagia without any other symptoms. Based on a videofluoroscopic swallowing study (VFSS), he showed decreased tongue base retraction, premature bolus loss, and incomplete velopharyngeal closure. He also showed impaired laryngeal elevation that caused incomplete laryngeal closure and aspiration with a small amount of thin fluid. Laryngoscopic evaluations, brain magnetic resonance imaging, and repetitive nerve stimulation tests were unremarkable. Since the acetylcholine receptor antibody level was elevated, he was diagnosed with MG. Treatment with pyridostigmine was initiated and the dysphagia symptoms improved completely. MG is one possible cause of unexplained dysphagia. Therefore, neurological examination is required when abnormal findings are observed in VFSS, and evaluations for MG may be important for the final diagnosis.

The Factors Associated With Health-Related Quality of Life in Stroke Survivors Age 40 and Older

OBJECTIVE: To evaluate the association between clinical and socio-demographic status and health-related quality of life (HR-QoL) in stroke survivors age 40 and older in the Korean population. METHODS: The relationship between stroke and HR-QoL was investigated using data from the Korea National Health and Nutrition Examination Survey (KNHANES), conducted from 2007–2012. The total number of respondents was 24,050 and 757 stroke survivors were included. Specifically, we investigated factors associated with the lowering of HR-QoL in a group of Korean adult stroke patients age 40 and older after adjusting for socio-demographic factors, anthropometric measurements, and clinical comorbidities. Adjusted effects of covariates on EuroQol-visual analog scales (EQ-VAS) scores were estimated with a complex-samples general linear model and multivariate-adjusted odds ratios of the lowest quintile versus highest quintile of the EQ-VAS scores in the stroke group were estimated with a complex-samples logistic regression model. RESULTS: Socio-demographic, anthropometric factors, and clinical comorbidities significantly differed between the stroke and non-stroke groups, except regarding gender and residential area. The EQ-VAS was significantly lower in the stroke than non-stroke group. Anxiety/depression problems significantly lowered EQ-VAS, as did low education level, smoking, mobility and usual activities problems. Also, aging in 1-year increments and cardiovascular disease had a significant effect on lower EQ-VAS in stroke survivors. CONCLUSION: People with a stroke have significantly lower HR-QoL than healthy subjects. Therefore, managing depression, smoking, or cardiovascular disease and maintenance of physical function may be priority goals in improving HR-QoL after a stroke.

Characteristics of Patients Injured in Road Traffic Accidents According to the New Injury Severity Score

OBJECTIVE: To investigate the clinical characteristics of patients involved in road traffic accidents according to the New Injury Severity Score (NISS). METHODS: In this study, medical records of 1,048 patients admitted at three hospitals located in different regions between January and December 2014 were retrospectively reviewed. Only patients who received inpatient treatments covered by automobile insurance during the period were included. Accidents were classified as pedestrian, driver, passenger, motorcycle, or bicycle; and the severity of injury was assessed by the NISS. RESULTS: The proportion of pedestrian traffic accident (TA) was the highest, followed by driver, passenger, motorcycle and bicycle TA. The mean NISS was significantly higher in pedestrian and motorcycle TAs and lower in passenger TA. Analysis of differences in mean hospital length of stay (HLS) according to NISS injury severity revealed 4.97±4.86 days in the minor injury group, 8.91±5.93 days in the moderate injury group, 15.46±11.16 days in the serious injury group, 24.73±17.03 days in the severe injury group, and 30.86±34.03 days in the critical injury group (p<0.05). CONCLUSION: The study results indicated that higher NISS correlated to longer HLS, fewer home discharges, and increasing mortality. Specialized hospitals for TA patient rehabilitation are necessary to reduce disabilities in TA patients.

Paralysis Developing as a Paradoxical Response During the Treatment for Tuberculous Spondylitis: A Case Report

It can be difficult for clinicians to distinguish a paradoxical response to antituberculous therapy, worsening of an existing lesion despite adequate treatment, treatment failure, and drug resistance. We report a case of a 69-year-old woman who experienced bilateral lower extremity paralysis secondary to a paradoxical response. She had been suffering for 1 month from low back pain, due to tuberculous spondylitis. Her low back pain improved after antituberculous therapy. The low back pain, however, reappeared 2 months after treatment, accompanied by newly developed lower extremity weakness. Imaging studies showed an increased extent of her previous lesions. Consequently, the patient underwent a vertebral corpectomy with interbody fusion of the thoracolumbar spine. Histopathological examination showed chronic inflamed granulation tissue with no microorganisms. Although the antituberculous medication was not changed, the patient's symptoms and signs, including the paralysis, resolved after surgery.

Validity of Motor Impairment Scale in Long-Term Care Insurance System of Korea

OBJECTIVE: To validate the Motor Impairment Scale (MIS) of the Korean long-term care insurance (LTCI) system by comparing with the service time offered for aiding activities of daily living (ADL) and the ADL score. METHODS: A total of 407 elderly subjects without dementia who had used LTCI services were included in this study. Spearman correlations and multivariate linear regression models were employed to determine the relationship of the upper and lower limb MIS (U-MIS and L-MIS, respectively) to the service time and ADL. Stratified analyses for the facility group (n=121) and the domiciliary group (n=286) were performed. RESULTS: There were significant differences in characteristics between facility group and domiciliary group. The MIS was significantly correlated with service time in facility group (Spearman p=0.41 for U-MIS, Spearman p=0.40 for L-MIS). After adjusting for age, sex, and cognition score, U-MIS was an independent predictor for service time in facility group (p=0.04). In domiciliary group, no significant correlation was found between the MIS and service time. The MIS correlated with all of the ADL items and total ADL score in both groups. After adjusting for other factors including age, sex, and cognitive score, U-MIS and L-MIS were independent variables for explaining the total ADL score in both groups. CONCLUSION: The validity of the MIS as an evaluation tool in the physically-disabled elderly is higher in facility group than in domiciliary group. As an easy, objective, and simple method, MIS can be a useful tool in the LTCI system of Korea.

Validity and Reliability of the Korean Version of the MD Anderson Dysphagia Inventory for Head and Neck Cancer Patients

OBJECTIVE: To translate the MD Anderson Dysphagia Inventory (MDADI) which is a self-administered questionnaire that assesses effect of dysphagia on the quality of life for patients with head and neck cancer, into Korean and to verify the validity and reliability of the Korean version of MDADI. METHODS: We performed 6 steps for the cross-cultural adaptation which consisted of translation, synthesis, back translation, review by an expert committee, cognitive debriefing, and final proof reading. A total of 34 dysphagia patients with head and neck cancers from Seoul National University Hospital answered the translated version of the questionnaire for the pre-testing. The patients answered the same questionnaire 2 weeks later to verify the test-retest reliability. RESULTS: One patient was excluded at second survey because he changed his feeding strategy. Overall, 33 patients completed the study. Linguistic validations were achieved by each step of cross-cultural adaptation. We gathered statistically strong construct validity (Spearman rho for subdomain scores to total score correlation range from 0.852 to 0.927), internal consistency for subdomains (Cronbach's alpha coefficients range from 0.785 to 0.889) and test-retest reliability (intra-class correlation coefficient range from 0.820 to 0.955) CONCLUSION: The Korean version of the MDADI achieved linguistic validations and demonstrated good construct validity and reliability. It can be a useful tool for screening and treatment planning for the dysphagia of patients with head and neck cancers.
