Dysphagia Requiring Medical Attention in Parkinson’s Disease:A Korean Population-Based Study

Background@#Patients with Parkinson’s disease (PD) experience both motor and non-motor symptoms, including dysphagia. Although PD is closely associated with dysphagia, the prevalence or risk of dysphagia in PD is unclear, especially in Asian countries. @*Methods@#The prevalence of PD and dysphagia with PD in the general population was analyzed using the Korean National Health Insurance Service (NHIS) database. The prevalence per 100,000 persons of PD and dysphagia with PD from 2006 to 2015 was analyzed in the general population aged ≥ 40 years. Patients newly diagnosed with PD between 2010 and 2015 were compared with those without PD. @*Results@#The prevalence of PD and dysphagia in patients with PD increased continuously during the study period and was highest in the ninth decade of life. The percentage of patients with dysphagia in patients with PD increased with age. Patients with PD showed an adjusted hazard ratio of 3.132 (2.955–3.320) for dysphagia compared to those without PD. @*Conclusion@#This nationwide study showed increasing trends in the prevalence of PD and dysphagia among patients with PD in Korea between 2006 and 2015. The risk of dysphagia was three times higher in patients with PD than that in those without PD, highlighting the importance of providing particular attention.

Extravasation of the Contrast Material During Voiding Cystourethrography in a Chronic Spinal Cord Injury Patient: A Case Report

Neurogenic bladder is common in most spinal cord injury patients. Voiding cystourethrography (VCUG) is recommended in these patients to detect urinary tract complications. However, rare but serious complications may occur during VCUG, although VCUG is generally safe. There are several case reports of bladder rupture occurring in pediatric patients. Here, we report the first case of iatrogenic bladder rupture in an adult spinal cord injury patient in Korea. Particularly, extravasation of contrast without manual instillation has hardly ever been reported. To the best of our knowledge, this is the first reported case of bladder rupture without manual instillation during VCUG. We report a case of a 59-year-old female with paraplegia due to tuberculous spondylitis who underwent VCUG as a part of routine evaluation of neurogenic bladder. Extravasation of the contrast media during VCUG developed as a complication and the patient recovered spontaneously without any intervention. Therefore, VCUG should be performed properly in chronic spinal cord injury patients.

Prevalence and Clinical Characteristics of Noncardiac Chest Pain with Reflux Esophagitis in Korea

BACKGROUND/AIMS: Noncardiac chest pain (NCCP) is substernal, squeezing chest pain, unrelated to the cardiac problem. Our study aimed to define the prevalence and clinical characteristics of reflux esophagitis in NCCP patients in Korea. MATERIALS AND METHODS: We reviewed medical records of patients who visited Department of Cardiology, St. Paul's Hospital due to chest pain and had normal coronary arteriography and who had received endoscopy within 6 months. Patients diagnosed with peptic ulcer or gastric cancer were excluded. The patients were classified into two groups according to their endoscopic results; the reflux esophagitis group and the control group. RESULTS: Two hundred seventeen NCCP patients were enrolled and 96 patients (44.2%) were diagnosed with reflux esophagitis: 68 patients (31.3%) with minimal change esophagitis; 26 patients (12.0%) with Los Angeles (LA) grade A; 2 patients (0.9%) with LA grade B. There were no patients with severe erosive reflux disease. There were no significantly different characteristics in the reflux esophagitis group and the control group. CONCLUSIONS: The prevalence of reflux esophagitis in NCCP patients in Korea was 44.2%. Most patients had mild reflux esophagitis.
