Factors Influencing Facial Paralysis Recovery: A Retrospective Cohort Study Using Electronic Medical Records.

This study aims to report on treatment outcomes and related factors in Bell's palsy patients by analyzing Electronic Medical Records (EMR) data. To assess the impact on the duration until improvement in House-Brackmann grading post-onset, we conducted an analysis of inpatient records for Bell's palsy patients admitted to a traditional Korean medicine hospital from 2018 to 2022. A total of 1049 subjects were included in the analysis. Contributing factors to a duration of more than 14 days until improvement in HB Grade included age 40 or above, male gender, an initial period of more than 7 days from onset to admission, a history of past recurrence, and the indication for adjunctive therapy. To generalize the adaptation of adjunctive traditional Korean medicine treatment indications to treatment outcomes, larger-scale studies encompassing a broader patient population will be necessary.

Elevated prevalence and treatment of sleep disorders from 2011 to 2020: a nationwide population-based retrospective cohort study in Korea.

OBJECTIVES: This study used National Health Insurance claims data from Korea to report the prevalence of sleep disorders and treatment status, including traditional Korean medicine, in the last 10 years. METHODS: This is a retrospective cohort study in Korea. All diagnosis and prescription data, including herbal medicine claims, from the Health Insurance Review and Assessment Service from 2011 to 2020 were reviewed. Prevalence estimation, direct medical expenses and prescribed amounts for sleep disorders were recorded. RESULTS: The prevalence of sleep disorders increased from 3 867 975 (7.62%) in 2011 to 7 446 846 (14.41%) in 2020, nearly doubling over 10 years. Insomnia was observed in 91.44% (n=9 011 692) of the patients. The mean number of hospital visits per patient for sleep disorders was 11.5 (±26.62). Benzodiazepines are the most commonly prescribed medications for sleep disorders, and gamma-isoyosan is the most frequently prescribed herbal medicine. CONCLUSIONS: Sleep disorders are continuously increasing, as is the use of medical services-personal and social medical expenses are also increasing accordingly. Sleep disorders should be recognised as a significant health problem that needs to be actively addressed to improve quality of life.

The Impact of Early Acupuncture on Bell's Palsy Recurrence: Real-World Evidence from Korea.

Evidence-based treatment for Bell's palsy includes the administration of steroids within 3 days of symptom onset. Additionally, a few studies have suggested the importance of combining early acupuncture treatment in the acute phase of Bell's palsy with steroids. This study aimed to observe the impact of early acupuncture for Bell's palsy using real-world health insurance data in Korea. This retrospective study extracted data from 45,986 adult patients with Bell's palsy who received steroids between 2015 and 2017 with a follow-up period of at least 3 years until 2020 from the Korea National Health Insurance database. They were divided into the early acupuncture group (n = 28,267) and the comparison group (n = 17,719) based on the presence of an acupuncture treatment code within 7 days of diagnosis. The impact of early acupuncture on the likelihood of Bell's palsy recurrence was evaluated using multivariate logistic regression. The patients in the early acupuncture group had a lower likelihood of recurrence (odds ratio: 0.81, 95% confidence interval: 0.69-0.95). This study observed a beneficial impact of early acupuncture on Bell's palsy using real-world health insurance data in Korea. Further research is required to confirm these findings.

The incidence of new vertebral compression fractures in women after kyphoplasty and factors involved.

PURPOSE: To identify the incidence of new vertebral compression fractures in women after kyphoplasty and to analyze influential factors in these patients. MATERIALS AND METHODS: One hundred and eleven consecutive female patients with osteoporotic vertebral compression fractures (VCFs) underwent kyphoplasty at 137 levels. These patients were followed for 15.2 months postoperatively. For the survey of new vertebral compression fractures, medical records and x-rays were reviewed, and telephone interviews were conducted with all patients. RESULTS: During that time 20 (18%) patients developed new VCFs. The rate of occurrence of new VCFs in one year was 15.5% using a Kaplan-Meier curve. Body mass index (BMI), symptom duration and kyphoplasty level were the statistically significant factors between the patient groups both with and without new VCFs after kyphoplasty. In the comparison between the adjacent and remote new VCF groups, the adjacent new VCF group showed a larger amount of polymethyl methacrylate (PMMA) use during kyphoplasty (p<0.05). Before kyphoplasty, 9.9% of the patients had been prescribed medication for osteoporosis, and 93.7% of the patients started or continued medication after kyphoplasty. The development of new VCFs was affected by the number of vertebrae involved in the kyphoplasty. However, the lower incidence rate (15.5%) of new compression fractures might be due to a greater percentage (93.7% in our study) of patients taking anti-osteoporotic medication before and/or after kyphoplasty. CONCLUSION: When kyphoplasty is planned for the management of patients with osteoporotic VCFs, the application of a small amount of PMMA can be considered in order to lower the risk of new fractures in adjacent vertebrae. The postoperative use of anti- osteoporotic medication is recommended for the prevention of new VCFs.

Anti-angiogenic activity of the methanol extract and its fractions of Ulmus davidiana var. japonica.

This study aimed to elucidate anti-angiogenic activity of Ulmus davidiana var. japonica that has been widely used in folk medicine. The methanol extract (UDE) of Ulmus davidiana var. japonica concentration-dependently displayed a strong inhibition in the chick chorioallantoic membrane (CAM) angiogenesis. The n-butanol fraction of UDE and subsequent 30% MeOH subfraction were identified to be most responsible for the anti-angiogenic activity.

Anti-inflammatory and anti-angiogenic activities of Gastrodia elata Blume.

Gastrodia elata Blume rhizome has been traditionally used as a folk medicine for centuries in Oriental countries. Its ethanol extract (GEE) and subsequent fractions were used to evaluate anti-angiogenic, anti-inflammatory and related activities of Gastrodia elata. GEE potently inhibited angiogenesis in the chick chorioallantoic membrane assay, and its n-butanol fraction (BuOH) exerted the higher inhibitory effect. In a dose-dependent manner, GEE inhibited vascular permeability induced by acetic acid. GEE and its BuOH fraction exerted an inhibitory activity on exudate production, leukocyte migration and nitric oxide (NO) level in rat air-pouch model. GEE caused a dose-dependent inhibition of acetic acid-induced abdominal writhing in mice. In addition, GEE inhibited NO production and expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) upon stimulation by lipopolysaccharide (LPS) in RAW264.7 macrophages. In summary, we demonstrate some novel pharmacological activities of Gastrodia elata, such as anti-angiogenic, anti-inflammatory and analgesic activities, and in vivo and in vitro inhibitory activity on NO production.
