Background: This study investigated the impact of premorbid functional dependency on post-stroke mortality in patients with anterior circulation stroke (ACS) and posterior circulation stroke (PCS). Methods: This study enrolled 9,698 patients who experienced ischemic stroke between January 2011 and December 2022. The patients were classified into the ACS and PCS groups. Premorbid functional dependency was defined as modified Rankin Scale of ≥3. The risks of premorbid functional dependency and mortality at 3 months and 1-year post-stroke were assessed. A subgroup analysis was further performed to evaluate the risk of premorbid functional dependency in patients who underwent intravenous thrombolysis and endovascular treatment (EVT). Results: Among 6,358 patients with ACS and 3,340 with PCS, those with premorbid dependency were older, predominantly female, and had a higher proportion of vascular risk factors and stroke severity. Premorbid functional dependency was associated with increased mortality at both 3 months and 1 year in the PCS (odds ratio [OR], 1.79; 95% confidence interval [CI], 1.00–3.13; P=0.04 and OR, 2.87; 95% CI, 1.86–4.38; P<0.001, respectively), but not in the ACS (OR, 1.08; 95% CI, 0.77–1.51; P=0.639 and OR, 1.22; 95% CI, 0.93–1.59; P=0.140, respectively) group. Among patients who underwent EVT, premorbid functional dependency increased the risk of mortality at 1 year in the ACS group (OR, 1.80; 95% CI, 1.04–3.08; P=0.034), but was not associated with the risk in the PCS group (OR 2.56; 95% CI 0.64–10.15; P=0.176). Conclusion Premorbid functional dependency increases the risk of mortality in patients with PCS.

Background: This study focuses on the establishment and operation of a stroke patient hotline program to help patients and their caregivers determine when acute neurological changes require emergency attention.Method: The stroke hotline was established at the Gyeonggi Regional Cerebrovascular Center, Seoul National University Bundang Hospital, in June 2016. Patients diagnosed with stroke during admission or in outpatient clinics were registered and provided with stroke education. Consulting nurses managed hotline calls and made decisions about outpatient schedules or emergency room referrals, consulting physicians when necessary. The study analyzed consultation records from June 2016 to December 2020, assessing consultation volumes and types. Outcomes and hotline satisfaction were also evaluated. Results: Over this period, 6,851 patients were registered, with 1,173 patients (18%) undergoing 3,356 hotline consultations. The average monthly consultation volume increased from 29.2 cases in 2016 to 92.3 cases in 2020. Common consultation types included stroke symptoms (22.3%), blood pressure/glucose inquiries (12.8%), and surgery/procedure questions (12.6%). Unexpected outpatient visits decreased from 103 cases before the hotline to 81 cases after. Among the 2,244 consultations between January 2019 and December 2020, 9.6% were recommended hospital visits, with two cases requiring intra-arterial thrombectomy. Patient satisfaction ratings of 9–10 points increased from 64% in 2019 to 69% in 2020. Conclusion The stroke hotline program effectively reduced unexpected outpatient visits and achieved high patient satisfaction.Expanding the program could enhance the management of stroke-related neurological symptoms and minimize unnecessary healthcare resource utilization.

Background/Aims: The prospective Crohn’s Disease Clinical Network and Cohort Study is a nationwide multicenter cohort study of patients with Crohn’s disease (CD) in Korea, aiming to prospectively investigate the clinical features and long-term prognosis associated with CD. Methods: Patients diagnosed with CD between January 2009 and September 2019 were prospectively enrolled. They were divided into two cohorts according to the year of diagnosis: cohort 1 (diagnosed between 2009 and 2011) versus cohort 2 (between 2012 and 2019). Results: A total of 1,175 patients were included, and the median follow-up duration was 68 months (interquartile range, 39.0 to 91.0 months). The treatment-free durations for thiopurines (p<0.001) and anti-tumor necrosis factor agents (p=0.018) of cohort 2 were shorter than those of cohort 1. Among 887 patients with B1 behavior at diagnosis, 149 patients (16.8%) progressed to either B2 or B3 behavior during follow-up. Early use of thiopurine was associated with a reduced risk of behavioral progression (adjusted hazard ratio [aHR], 0.69; 95% confidence interval [CI], 0.50 to 0.90), and family history of inflammatory bowel disease was associated with an increased risk of behavioral progression (aHR, 2.29; 95% CI, 1.16 to 4.50). One hundred forty-one patients (12.0%) underwent intestinal resection, and the intestinal resection-free survival time was significantly longer in cohort 2 than in cohort 1 (p=0.003). The early use of thiopurines (aHR, 0.35;95% CI, 0.23 to 0.51) was independently associated with a reduced risk of intestinal resection. Conclusions The prognosis of CD in Korea appears to have improved over time, as evidenced by the decreasing intestinal resection rate. Early use of thiopurines was associated with an improved prognosis represented by a reduced risk of intestinal resection.

Objectives: The purpose of this study was to analyze several factors affecting the efficacy of epidural steroid injections as a nonoperative treatment modality in lumbar disc herniation patients.Summary of Literature Review: Despite several studies, the normal course of intervertebral disc herniation is not fully understood, and the optimal timing of surgery is unclear. Methods: From January 2017 to April 2019, among outpatients in our hospital, 64 patients diagnosed with 3-4 or 4-5 single-level lumbar disc herniation and followed up for at least 6 weeks were included. Epidural steroid injection was performed in all patients during their 1-week admission. Symptoms improved in 36 patients (group 1) and persisted or recurred in 28 patients (group 2), who were finally treated surgically. Demographic factors, magnetic resonance imaging findings, and clinical assessments were analyzed. Results: The only demographic factor with a significant difference between groups was symptom duration. In magnetic resonance imaging, significant differences were found in disc sequestration and the degree of the herniated disc. At 6 weeks after the injection, significant differences were found between the 2 groups in visual analog scale scores and the Korean version of the Oswestry Disability Index. Conclusions Several factors must be considered when treating patients with lumbar disc herniation. Of note, longer symptom duration was found to be associated with a lower effectiveness of conservative treatment. The effects of treatment could also be influenced by the disc form and the degree of disc herniation.

PURPOSE: The aim of the present investigation was to understand the incidence, prevalence of denture stomatitis in denture wearers, who were over 60 years old, and use the results for a fundamental data to promote public awareness about denture stomatitis and its education tools. MATERIALS AND METHODS: From August 21 to September 8 2017, 500 denture wearers, who were more than 60 years old in Seoul and 4 other metropolitan cities (Busan, Daegu, Gwangju, and Daejeon), received questionnaires. The questionnaires included denture wearers' demographic distributions, specific dental treatment experiences, discomforts with current dentures, their oral health conditions, and the method of denture cleansing. RESULTS: Thirty-two percent of 500 denture wearers responded that they have healthy oral conditions. Two hundred and eight respondents (41.6%) were aware of denture stomatitis. Only 131 (26.2%) were informed about the removable denture covered by national health insurance and 327 (65.4%) of denture wearers were using the improper denture cleansing methods. CONCLUSION: A large number of denture wearers still do not recognize the importance of proper treatment for denture stomatitis, insurance covered denture treatments, and adequate denture cleansing methods.

A 78-year-old right handed man with hypertension presented with sudden onset dysarthria and right hemiparesis. Magnetic resonance angiography revealed near-occlusion of left proximal internal carotid artery. Emergent carotid stenting was performed. On the 17th day after carotid stenting, he showed decreased consciousness. Magnetic resonance imaging (MRI) showed edematous change with high signal and increased perfusion in the left hemisphere. Our case shows that delayed cerebral hyperperfusion syndrome can occur even 2 weeks after carotid artery stenting and multimodal MRI can help accurate diagnosis.

We present a patient who complained of excessive daytime sleepiness (EDS), which started three years ago. She had no other medical, neurological, and psychiatric disorders. Nocturnal polysomnography did not indicate any sleep disorders, which might cause daytime EDS, such as obstructive sleep apnea. The following multiple sleep latency test was not compatible for narcolepsy. Her laboratory findings were remarkable for subclinical hypothyroidism, although free T4 and T3 were within reference rage, she had elevated thyroid stimulating hormone. After four weeks of levothyroxine treatment, her EDS resolved. The hypersomnolence, as a presenting symptom of subclinical hypothyroidism, was optimally treated after thyroid hormone replacement.
