ABSTRACT
Purpose@#Polypharmacy can cause drug-related problems, such as potentially inappropriate medication (PIM) use and medication regimen complexity in the elderly. This study aimed to investigate the feasibility and effectiveness of a collaborative medication review and comprehensive medication reconciliation intervention by a pharmacist and hospitalist for older patients. @*Materials and Methods@#This comprehensive medication reconciliation study was designed as a prospective, open-label, randomized clinical trial with patients aged 65 years or older from July to December 2020. Comprehensive medication reconciliation comprised medication reviews based on the PIM criteria. The discharge of medication was simplified to reduce regimen complexity. The primary outcome was the difference in adverse drug events (ADEs) throughout hospitalization and 30 days after discharge. Changes in regimen complexity were evaluated using the Korean version of the medication regimen complexity index (MRCI-K). @*Results@#Of the 32 patients, 34.4% (n=11/32) reported ADEs before discharge, and 19.2% (n=5/26) ADEs were reported at the 30-day phone call. No ADEs were reported in the intervention group, whereas five events were reported in the control group (p=0.039) on the 30-day phone call. The mean acceptance rate of medication reconciliation was 83%. The mean decreases of MRCI-K between at the admission and the discharge were 6.2 vs. 2.4, although it was not significant (p=0.159). @*Conclusion@#As a result, we identified the effect of pharmacist-led interventions using comprehensive medication reconciliation, including the criteria of the PIMs and the MRCI-K, and the differences in ADEs between the intervention and control groups at the 30-day follow-up after discharge in elderly patients.Trial Registration: (Clinical trial number: KCT0005994)
ABSTRACT
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.
ABSTRACT
Background@#Assessing and improving the quality of trauma care is crucial in modern trauma systems and centers. In Korea, evaluations of regional trauma centers are conducted annually to assess and improve trauma management quality. This includes using the Trauma and Injury Severity Score (TRISS) method to calculate the W-score and mortality Observed-to-Expected ratio (O:E ratio), which are used to evaluate the quality of care. We analyzed the potential for overestimation of the probability of survival using TRISS method for patients with neurotrauma, as well as the potential for errors when evaluating and comparing regional trauma centers. @*Methods@#We included patients who visited the regional trauma center between 2019 and 2021 and compared their probability of survival of the TRISS method, W-score, mortality O:E ratio, and misclassification rates. The patient groups were further subdivided into smaller subgroups based on age, Glasgow Coma Scale (GCS), and Injury Severity Score, and comparisons were made between the neurotrauma and non-neurotrauma groups within each subgroup. @*Results@#A total of 4,045 patients were enrolled in the study, with 1,639 of them having neurotrauma. The neurotrauma patient group had a W-score of −0.68 and a mortality O:E ratio of 1.044. The misclassification rate was found to be 13.3%, and patients with a GCS of 8 or less had a higher misclassification rate of 37.4%. @*Conclusion@#The limitations of using the TRISS method for predicting outcomes in patients with severe neurotrauma are exposed in this study. The TRISS methodology demonstrated a high misclassification rate of approximately 40% in subgroups of patients with GCS less than 9, indicating that it may be less reliable in predicting outcomes for severely injured patients with low GCS. Clinicians and researchers should be cautious when using the TRISS method and consider alternative methods to evaluate patient outcomes and compare the quality of care provided by different trauma centers.
ABSTRACT
Objective@#Patients recovering from moderate-to-severe coronavirus disease 2019 (COVID-19) reportedly have dysphagia or difficulty in swallowing. The current study compares the differences in dysphagia characteristics arising from COVID-19 pneumonia and aspiration pneumonia. We further identify factors affecting the severity of dysphagia. @*Methods@#Fifty-four patients diagnosed with COVID-19 pneumonia with dysphagia and 44 patients with aspiration pneumonia were referred for a videofluoroscopic swallowing study (VFSS) since they presented with signs and symptoms of dysphagia. The electronic medical records were reviewed to compare the dysphagia characteristics of the patients. @*Results@#Intensive care unit (ICU) admission, intubation, tracheostomy, and a diagnosis of Acute Respiratory Distress Syndrome (ARDS) after admission were more common in patients with COVID-19 pneumonia (P＜0.001 for other variables and P=0.007 for tracheostomy) than in patients with aspiration pneumonia. Compared to patients with aspiration pneumonia, the COVID-19 patients had a significantly higher total modified videofluoroscopic dysphagia scale (mVDS) score, indicating more severe dysphagia (P=0.038). Among the mVDS sub-scores, tracheal aspiration was significantly higher in the COVID-19 pneumonia group (P＜0.001). In logistic regression analysis, age (P=0.034), COVID-19 (P=0.001), ICU admission (P=0.012), tracheostomy (P=0.029), and ARDS diagnosis after admission (P=0.036) were significantly associated with tracheal aspiration. After adjusting for age, sex, comorbidities, and clinical variables, COVID-19 was still significantly associated with worse tracheal aspiration scores (P=0.042). @*Conclusion@#Patients with COVID-19 pneumonia showed more severe dysphagia than subjects with aspiration pneumonia. This is particularly related to tracheal aspiration, as revealed by the VFSS. The dysphagia also correlated with a greater incidence of ICU admission, intubation, tracheostomy, and ARDS diagnosis in the COVID-19 pneumonia group.
ABSTRACT
Background@#and Purpose This study aimed to identify the epidemiological features of Guillain-Barré syndrome (GBS) in the Korean population. @*Methods@#Patients with GBS were defined as those who were hospitalized with a primary diagnostic code of G61.0 on the Korean Classification of Disease in a department of neurology, rehabilitation medicine, or pediatrics. We evaluated the incidence and prevalence of GBS as well as physical disability, mortality, and cause of death in patients with GBS from 2002 to 2018 in the Korean population using the Korean National Health Insurance Service database. @*Results@#We identified 11,146 patients with GBS. The ratio of males to females was 1.48. The age-adjusted incidence rate per 100,000 persons increased steadily from 0.84 in 2002 to 1.68 in 2018, as did the age-adjusted prevalence rate per 100,000 persons, from 0.77 to 15.62. The incidence and prevalence of GBS increased with age, peaking at 70–79 years. Among 10,114 patients without physical disability at the time of GBS being diagnosed, 502 (5.0%) patients had moderate disability and 526 (5.2%) had severe disability by the end of the study period.A total of 1,221 (11.0%) patients with GBS died during the mean follow-up period of 17 years (2002–2019). There were 144 (1.3%) in-hospital deaths. @*Conclusions@#This was the first nationwide epidemiological study of patients with GBS covering the entire population including patients of all ages in the Republic of Korea. We have revealed the seasonality of admissions, disability, and long-term mortality rates in patients with GBS.
ABSTRACT
Shunt malfunction is the most common cause of ventriculoperitoneal shunt failure. In literature, occlusion of the tube with brain parenchyma, choroid plexus, blood, and proteinaceous debris has been suggested as a mechanism of obstruction. We herein report a case of shunt malfunction without any identifiable occlusion. Our case findings suggest that unapparent abdominal pathology, including inflammation and fibrosis, should be considered when treating shunt failures.
ABSTRACT
Objective@#The Rotterdam scoring system (RSS) is useful for prognosis prediction in patients with severe traumatic brain injury (sTBI). It comprises basal cistern, midline shifting (MLS), epidural hematoma (EDH), and subarachnoid hemorrhage (SAH)/intraventricular hemorrhage (IVH) status. Brain computed tomography (CT) is important to assessing patients with sTBI; however, results often change over time. We aimed to determine whether RSS outcome prediction differs by initial brain CT scan time after the trauma in patients with sTBI. @*Methods@#We used data from the second Korea Neurotrauma Data Bank, and analyzed 455 patients; RSS, Glasgow Outcome Scale Extended (GOSE) on 6-months, and the CT scan time were obtained. Unfavorable outcomes were defined as a GOSE score of 1–4. Participants were divided into 2 groups according to when brain CT scan was performed (> or ≤ 2 hours after trauma). The relationship between the prognosis of patients with sTBI and RSS score was examined by calculating the odds ratios. Univariate and multivariate analyses were performed. @*Results@#In both univariate and multivariate analysis, the total RSS and basal cistern status were statistically correlated with prognosis in both groups. EDH and SAH/IVH showed statistically significant difference according to CT scan time. MLS was associated with prognosis in both groups in univariate analysis although not in multivariate analysis. @*Conclusion@#The total RSS score predicted prognosis 6 months after trauma in patients with sTBI, regardless of CT scan time. However, the prognostic predictive power of each item constituting the RSS varied according to CT scan time.
ABSTRACT
A dural arteriovenous fistula (DAVF) is a pathologic arteriovenous shunt located within the dural wall of a venous sinus. In addition, DAVFs are associated with sinus thrombosis. Consequently, sinus occlusion may occur near DAVF lesions, making treatment challenging. However, there are few reports of sinus occlusion unrelated to lesions. In this study, we present a rare case of contralateral transverse sinus occlusion in a patient who underwent endovascular treatment and stereotactic radiosurgery for DAVF in the transverse-sigmoid sinus with ipsilateral sigmoid sinus occlusion.
ABSTRACT
As coronavirus disease 2019 (COVID-19) has spread worldwide, the rate of COVID-19 vaccination uptake is encouraging. Neurological complications associated with COVID-19 vaccines such as stroke, Guillain-Barré syndrome, and Bell’s palsy have been reported.Recently, late-onset myasthenia gravis (MG) following COVID-19 vaccination has been reported. To date, however, there has been no evidence of increased risk of early-onset MG following COVID-19. Here, we report a case of a patient with new-onset MG that arose after receiving a COVID-19 vaccine. A 33-year-old woman suddenly experienced generalized weakness and diplopia on the evening she had received the second dose of the PfizerBioNTech COVID-19 vaccine. The temporal relationship suggests that this new-onset MG is related to the vaccination. It also implies that COVID-19 vaccination could trigger early-onset MG symptoms in patients at risk of MG.
ABSTRACT
Contrast-induced encephalopathy (CIE) following cerebral angiography has similar clinical presentations to ischemic complications of cerebral angiography. Neurologic deficits in CIE are mostly transient, but those caused by acute cerebral infarction (ACI) as ischemic complications of cerebral angiography may be permanent. Therefore, distinguishing CIE from ACI is important. Diffusion restriction on magnetic resonance imaging (MRI) implies ACI, while hyperintensity on diffusion weighted imaging (DWI) without correlation on the apparent diffusion coefficient (ADC) map implies CIE. We reported a rare case of CIE with diffusion restriction on MRI following cerebral angiography that mimicked MRI findings of ACI. The mechanism of this phenomenon remains unknown and requires further investigation.
ABSTRACT
This study was performed to evaluate the effects of microstructural change of zirconia surface on tensile bond strength with resin cement. The zirconia partially sintered block was cut into a size of 18 × 18 × 7 mm, and then the Zirface slurry (DMAX, Daegu, Korea) containing 15% and 30% zirconia was applied and followed by sintering at 1530 ℃ for 2 hours. Resin cement (PermaCem 2.0, DMG, Hamburg, Germany) was applied on zirconia specimen and polymerized to prepare an 18 × 18 × 14 mm block. In addition, for comparison of bond strength, specimens were prepared for the group that was polished and the group that was blasted at 3 atm using 110 µm alumina. Thereafter, all blocks were cut into a cross-sectional area of 1.0 × 1.0 mm to prepare 12 specimens. The specimens were immersed in distilled water at 37 ℃. for 10 days for aging treatment. A holder for tensile testing was attached to each of the specimens, and then a tensile force was applied at a crosshead speed of 0.5 mm/min to measure the fracture load. The fracture surfaces of each test piece was observed with a high-resolution field emission scanning electron microscope. Through the above tests, the following results were obtained. 1. On the blasted surface, zirconia grains were locally removed but on the Zirface treated surface, a porous microstructure was created on the zirconia surface. 2. Arithmetical mean deviation from the mean line ra was the highest in the blasted group and the lowest in the polished group, and as a result of Tukey analysis, there were statistically significant differences between all test groups (P<0.05). 3. The maximum tensile bond strength was 18.8±5.4 MPa in the Zirface 30% group, and as a result of Tukey analysis, there was a statistically significant difference from the other test groups (P<0.05). 4. As a result of observing the fracture surface after the tensile test with a high-resolution field emission scanning electron microscope, in the Zirface 30% group, cohesive fracture and interfacial fracture in the resin was observed, but the other test groups showed the interfacial fracture pattern. In conclusion, within the limits of this study, treating the zirconia surface with Zirface 30% to form a porous microstructure can contribute to the improvement of the bond strength between zirconia and resin cement.
ABSTRACT
Shock thyroid is a rare manifestation of the CT hypotension complex and can be diagnosed when thyroid and perithyroidal edemas are observed on CT during the onset of shock. Shock thyroid can be a useful CT sign for decompensated shock. This condition is reversible and recovers rapidly with adequate treatment. We present the case of an 84-year-old female with septic shock, exhibiting CT features consistent with a shock thyroid. We also reviewed the clinical and radiological findings reported in the literature. The present case emphasizes that shock thyroid can be an early indicator of impending hemodynamic instability and has important prognostic and therapeutic implications.
ABSTRACT
Background@#Pompe disease is a rare autosomal recessive disorder caused by the deficiency of a lysosomal enzyme, acid alpha-glucosidase (GAA). Early diagnosis and initiation of treatment with enzyme replacement therapy have remarkable effects on the prognosis of Pompe disease. We performed the expanded screening for late onset Pompe disease (LOPD) at eight centers in Korea. @*Methods@#From September 1, 2015, GAA activity were measured from both dried blood spot (DBS) and mixed leukocyte for 188 available patients. For 12 patients with low GAA activity, we performed Sanger sequencing of GAA gene. @*Results@#Among 188 patients, 115 were males. The mean of age of symptom onset and diagnosis were 34.3 years and 41.6 years. Among 12 patients with decreased GAA activity, two patients were confirmed to have LOPD with genetic test (c.1316T>A [p.M439K] + c.2015G>A [p.R672Q], c.1857C>G [p.S619R] + c.546G>C [leaky splicing]). Other two patients had homozygous G576S and E689K mutation, known as pseudodeficiency allele. @*Conclusions@#This study is expanded study of LOPD screening for targeted Korean population. We found two patients with LOPD, and the detection rate of LOPD is 1.06%. With application of modified GAA cutoff value (0.4), which was previously reported, there were no false positive results of GAA activity test using DBS. Therefore, it could be an appropriate screening test for LOPD in especially East-Asian population, in which pseudodeficiency allele is frequent.
ABSTRACT
Objective@#: The widely accepted treatment option of a traumatic carotid cavernous fistula (TCCF) has been detachable balloon or coils based fistula occlusion. Recently, covered stent implantation has been proving an excellent results. The purpose of this study is to investigate our experiences with first line choice of covered stent implantation for TCCF at level 1 regional trauma center. @*Methods@#: From November 2004 to February 2020, 19 covered stents were used for treatment of 19 TCCF patients. Among them, 15 cases were first line treatment using covered stents. Clinical and angiographic data were retrospectively reviewed. @*Results@#: Procedures were technically successful in all 15 cases (100%). Immediate angiographic results after procedure were total occlusion in 12 patients (80%). All patients except two expired patients had image follow-up (mean 15 months). Recurred symptomatic three patients underwent additional treatments and achieved complete occlusion. Mean clinical follow-up duration was 32 months and results were modified Rankin Scale 1–2 in five, 3–4 in five, and 5 in three patients. @*Conclusion@#: The covered stent could be considered as fist line treatment option for treating TCCF patients especially in unstable vital sign. Larger samples and expanded follow-up are required to further develop their specifications and indications.
ABSTRACT
Purpose@#Currently, the most recommended method for burn first aid is the cool running water for 20 minutes (CRW20). If CRW20 is not practicable, cooling dressing products with tea tree oil are used as substitutes. In this study, we analyze the effect of various burn first aids, including CRW20, cooling products, on the treatment period. @*Methods@#This study was conducted on patients who suffered burns and visited Hangangsoo Hospital from March 2019 to March 2020. The study conducted in a retrospective method. The duration of treatment was analyzed by dividing the experimental group. @*Results@#The treatment period was shortened when first aid was given (P＜0.001). Cold water, ice, and ice packs resulted in reduced treatment periods (P＜0.001, P=0.004). The treatment period was reduced when cooling dressing products were used in all groups (P=0.041). The implementation of first aid has reduced the duration of burn treatment. This means that cooling helps burn treatment. CRW20 did not show statistically meaningful results. This is the result of a failure to fully control the temperature and time of tap water. In addition, the change in temperature of tap water according to season, the use of water is higher than that of animal testing, and the general lack of information on proper burn first aid may have affected. @*Conclusion@#The treatment period was statistically significantly reduced in the group that performed first aid. Among the various first aid methods, cold water and ice reduced the treatment period.
ABSTRACT
Objective@#The incidence of hip fractures is increasing worldwide with the aging population, causing a challenge to healthcare systems due to the associated morbidities and high risk of mortality. After hip fractures in frail geriatric patients, existing comorbidities worsen and new complications are prone to occur. Comprehensive rehabilitation is essential for promoting physical function recovery and minimizing complications, which can be achieved through a multidisciplinary approach. Recommendations are required to assist healthcare providers in making decisions on rehabilitation post-surgery. Clinical practice guidelines regarding rehabilitation (physical and occupational therapies) and management of comorbidities/complications in the postoperative phase of hip fractures have not been developed. This guideline aimed to provide evidence-based recommendations for various treatment items required for proper recovery after hip fracture surgeries. Methods Reflecting the complex perspectives associated with rehabilitation post-hip surgeries, 15 key questions (KQs) reflecting the complex perspectives associated with post-hip surgery rehabilitation were categorized into four areas: multidisciplinary, rehabilitation, community-care, and comorbidities/complications. Relevant literature from four databases (PubMed, EMBASE, Cochrane Library, and KoreaMed) was searched for articles published up to February 2020. The evidence level and recommended grade were determined according to the grade of recommendation assessment, development, and evaluation method. Results A multidisciplinary approach, progressive resistance exercises, and balance training are strongly recommended. Early ambulation, weigh-bearing exercises, activities of daily living training, community-level rehabilitation, management of comorbidities/complication prevention, and nutritional support were also suggested. This multidisciplinary approach reduced the total healthcare cost. @*Conclusion@#This guideline presents comprehensive recommendations for the rehabilitation of adult patients after hip fracture surgery.
