ABSTRACT
Osteoarthritis (OA) is a chronic degenerative joint disease and the most common type of arthritis. It involves almost any joint and can lead to chronic pain and disability. In the late 19th century, Roentgen discovered X-rays, and then began to use radiotherapy to treat tumors. In the 1980s, Luckey thought that low-level radiation (LDRT) might be beneficial to biology, and it was gradually applied to the treatment of some diseases. This paper introduces the epidemiology, risk factors, clinical manifestations and treatment methods of OA, points out that the cartilage injury and the important effect of synovial inflammation in the pathogenesis of OA, namely when the homeostasis of articular cartilage are destroyed, synthetic metabolism and catabolism imbalances, cartilage cells damaged their breakdown products consumed by synovial cells. Synovial cells and synovial macrophages secrete proinflammatory cytokines, metalloproteinases and proteolytic enzymes, leading to cartilage matrix degradation and chondrocyte damage, which aggravates synovial inflammation and cartilage damage, forming a vicious cycle. The possible mechanism and clinical research progress of LDRT in alleviating OA are discussed. LDRT can regulate inflammatory response, inhibit the production of pro-inflammatory cytokines, and promote the production of anti-inflammatory cytokines, thereby achieving anti-inflammatory effect. Studies have shown that after irradiation, the expression of inducible nitric oxide synthase (iNOS) was decreased, the release of reactive oxygen species (ROS) and the production of superoxide were inhibited, the anti-inflammatory phenotype of macrophages was differentiated from M1 to M2, the inflammatory CD8+ T cells were transformed into CD4+ T cells, and the number of dendritic cells (DC) was significantly reduced. LDRT inhibit the production of proinflammatory factors in leukocytes, reduce their recruitment and adhesion, and down-regulate the expression levels of cell adhesion molecules such as selectin, intercellular adhesion molecule (ICAM) and vascular endothelial cell adhesion molecule (VCAM). LDRT can regulate endothelial cells, stimulate endothelial cells to produce a large amount of TGF-β1, reduce the adhesion of endothelial cells to peripheral blood mononuclear cells (PBMC), and contribute to the anti-inflammatory effect of LDRT. It also exerted anti-inflammatory effects by regulating mitochondrial growth differentiation factor 15 (GDF15). After low-level radiation, the MMP-13 (matrix metalloproteinases-13) and the ADAMTS5 (recombinant a disintegrin and metalloproteinase with thrombospondin-5) decreased, the Col2a1 (collagen type 2) increased in chondrocytes. In the existing clinical studies, most patients can achieve relief of joint pain and recovery of joint mobility after irradiation, and the patients have good feedback on the efficacy. The adverse reactions (acute reactions and carcinogenic risks) caused by LDRT in the treatment of OA are also discussed. During the treatment of OA, a few patients have symptoms such as redness, dryness or itching at the joint skin, and the symptoms are mild and do not require further treatment. Patients are thus able to tolerate more frequent and longer doses of radiotherapy. In general, LDRT itself has the advantages of non-invasive, less adverse reactions, and shows the effect of pain relief and movement improvement in the treatment of OA. Therefore, LDRT has a broad application prospect in the treatment of OA.
ABSTRACT
Background@#With the increasing number of internet users, search engines have become a widely used source of health-related information. However, evaluating the quality of medical information obtained through search engines can be challenging. This study aimed to evaluate the quality of search results related to breast implants obtained from major domestic websites in Korea using systematic evaluation standards. @*Methods@#Two main primary search terms (“gaseum” [breast] implant and “yubang” [breast] implant), along with 15 adjunct search terms, were combined and searched in Google, Naver, and Daum. The top 20 websites were evaluated and classified according to their type and provider. They were scored using the Korean Medical Association’s Internet Health Information Certification Standards. The proportion of significant websites, their categorical distribution, and the quality of information scores were then compared. @*Results@#Google yielded the highest number of appropriate results, with statistical significance. Blogs (36.4%) and news (34.8%) were the most common types of search results, while healthcare provider groups (49.5%) constituted the most common provider subgroup. Only 1.9% of the search results were from public organizations. Google had a significantly higher average quality score (14.04) than Naver (13.22), and Daum (12.45) (P<0.05). @*Conclusions@#Although almost half of the search results were provided by medical personnel, their average quality score (13.16) was below the overall average (13.36) and far below the 21 points of the journal/abstract category. The findings highlight the need for healthcare providers to provide high-quality medical information, and for users to develop high-level digital health literacy.
ABSTRACT
The superficial temporal artery (STA) bifurcates into frontal and parietal branches. The parietal branch is used as a recipient vessel for scalp reconstruction, but it is absent in approximately 16.3% of individuals. In this case, a 72-year-old woman with an occipital scalp defect lacked both the parietal branch of the STA and the superficial temporal vein. To address this anatomic variation, we used the frontal branch of the STA and the posterior auricular vein as alternative recipient vessels for anterolateral thigh free flap reconstruction. The surgical procedure involved end-to-end microvascular anastomosis of one artery and one vein. Partial flap necrosis occurred postoperatively, but eventually resolved with debridement. The frontal branch of the STA and the posterior auricular vein can serve as reliable alternatives in the absence of the parietal branch. Reconstructive surgeons should be aware of anatomic variations of the STA and adapt their surgical approach accordingly.
ABSTRACT
Purpose@#Post-transplantation lymphoproliferative disorders (PTLDs) after hematopoietic stem transplantation (HCT) or solid organ transplantation (SOT) result in poorer outcomes, including death. There are limited large cohort data on the incidence and natural course of PTLD in Asians. @*Materials and Methods@#We investigated PTLD using Korean national health insurance claims data of 47,518 patients who underwent HCT or SOT in 2008-2020. Patient demographics, time and type of PTLD diagnosis, type of PTLD treatment, and death data were collected. We used Fine and Gray subdistribution hazard models to calculate the cumulative incidence and risk factors for PTLD. @*Results@#During median follow-up of 5.32 years, PTLD occurred in 294 of 36,945 SOT patients (0.79%) and 235 of 10,573 HCT patients (2.22%). Cumulative incidence of PTLD were 0.49% at 1 year, 1.02% at 5 years, and 1.50% at 10 years post-transplantation. Age < 20 years (subdistribution hazard ratio [SHR] of 1.67 in age 10-19, SHR 1.51 in age 0-9), HCT (SHR 3.02), heart transplantation (SHR 2.27), and liver transplantation (SHR 1.47) were significant risk factors for PTLD. The presence of PTLD was associated with an increased risk of death (hazard ratio of 2.84). Overall, 5-year survival of PTLD patients was 68.9% (95% confidence interval, 64.9 to 73.2). @*Conclusion@#We observed a steady increase in PTLD over 10 years after HCT or SOT in this large cohort study. Pediatric age group, HCT, liver transplantation, and heart transplantation were suggested to be risk factors for PTLD, and PTLD was associated with a higher risk of death.
ABSTRACT
Objectives@#. This study aimed to compare the oncological outcomes of partial versus superficial or total parotidectomy for superficial T1 or T2 primary parotid cancers and investigate their prognostic factors and recurrence patterns. @*Methods@#. The medical records of 77 patients with T1–2 primary parotid malignancies between May 2003 and March 2022 were retrospectively reviewed. Univariate and multivariate analyses were performed to evaluate the prognostic factors associated with overall survival, disease-free survival, and local and distant recurrence. @*Results@#. The average follow-up duration was 70.2 months (range, 12–202 months). The 5-year overall and disease-free survival rates were 88.7% and 77.1%, respectively. Twenty-two patients underwent partial parotidectomy, and 55 underwent superficial or total parotidectomy. There were no significant differences in the disease recurrence (P=0.320) and mortality rates (P=0.884) of the partial and superficial or total parotidectomy groups. The mean duration of surgery was shorter and the overall complication rates were significantly lower in the partial group than in the superficial or total parotidectomy group (P=0.049). Sixteen cases of recurrence occurred during the study period (20.8%). Univariate analyses showed that high-grade tumors (P=0.006), lymphovascular invasion (P=0.046), and regional lymph node metastasis (P=0.010) were significant risk factors for disease recurrence. Multivariate analysis identified regional lymph node metastasis as an independent prognostic factor for disease recurrence (P=0.027), and lymphovascular invasion as an independent prognostic factor for overall survival (P=0.033). @*Conclusion@#. The conservative surgical approach of partial parotidectomy can yield oncological outcomes comparable to those of superficial or total parotidectomy with careful patient selection in T1-2 parotid cancers.
ABSTRACT
Chronic kidney disease is a significant health burden worldwide, with increasing incidence. Although several genome- wide association studies (GWAS) have investigated single nucleotide polymorphisms (SNP) associated with kidney trait, most studies were focused on European ancestry. Methods: We utilized clinical and genetic information collected from the Korean Genome and Epidemiology Study (KoGES). Results: More than five million SNPs from 58,406 participants were analyzed. After meta-GWAS, 1,360 loci associated with estimated glomerular filtration rate (eGFR) at a genome-wide significant level (p = 5 × 10–8) were identified. Among them, 399 loci were validated with at least one other biomarker (blood urea nitrogen [BUN] or eGFRcysC) and 149 loci were validated using both markers. Among them, 18 SNPs (nine known ones and nine novel ones) with 20 putative genes were found. The aggregated effect of genes estimated by MAGMA gene analysis showed that these significant genes were enriched in kidney-associated pathways, with the kidney and liver being the most enriched tissues. Conclusion: In this study, we conducted GWAS for more than 50,000 Korean individuals and identified several variants associated with kidney traits, including eGFR, BUN, and eGFRcysC. We also investigated functions of relevant genes using computational methods to define putative causal variants.
ABSTRACT
Objective@#This study investigated the feasibility and prognostic relevance of threshold-based quantification of myocardial delayed enhancement (MDE) on CT in patients with nonischemic dilated cardiomyopathy (NIDCM). @*Materials and Methods@#Forty-three patients with NIDCM (59.3 ± 17.1 years; 21 male) were included in the study and underwent cardiac CT and MRI. MDE was quantified manually and with a threshold-based quantification method using cutoffs of 2, 3, and 4 standard deviations (SDs) on three sets of CT images (100 kVp, 120 kVp, and 70 keV). Interobserver agreement in MDE quantification was assessed using the intraclass correlation coefficient (ICC). Agreement between CT and MRI was evaluated using the Bland-Altman method and the concordance correlation coefficient (CCC). Patients were followed up for the subsequent occurrence of the primary composite outcome, including cardiac death, heart transplantation, heart failure hospitalization, or appropriate use of an implantable cardioverter-defibrillator. The Kaplan–Meier method was used to estimate event-free survival according to MDE levels. @*Results@#Late gadolinium enhancement (LGE) was observed in 29 patients (67%, 29/43), and the mean LGE found with the 5-SD threshold was 4.1% ± 3.6%. The 4-SD threshold on 70-keV CT showed excellent interobserver agreement (ICC = 0.810) and the highest concordance with MRI (CCC = 0.803). This method also yielded the smallest bias with the narrowest range of 95% limits of agreement compared to MRI (bias, -0.119%; 95% limits of agreement, -4.216% to 3.978%). During a median follow-up of 1625 days (interquartile range, 712–1430 days), 10 patients (23%, 10/43) experienced the primary composite outcome. Event-free survival significantly differed between risk subgroups divided by the optimal MDE cutoff of 4.3% (log-rank P = 0.005). @*Conclusion@#The 4-SD threshold on 70-keV monochromatic CT yielded results comparable to those of MRI for quantifying MDE as a marker of myocardial fibrosis, which showed prognostic value in patients with NIDCM.
ABSTRACT
Non-variceal upper gastrointestinal bleeding (NVUGIB), which predominantly occurs secondary to peptic ulcers, presents a major challenge in emergency departments and is associated with high mortality rates. The staged approach used for management of NVUGIB comprises preendoscopy, endoscopy, and post-endoscopy. Proton pump inhibitors and prokinetics are used for pre-endoscopy preparation to improve visualization and outcomes. Various endoscopic hemostatic methods, including injection therapy, clipping, and thermal techniques are described, which reflects the need for personalized strategies based on patient conditions and lesion characteristics. Post-endoscopic care includes continuous acid suppression therapy and selective second-look endoscopy. Overall, the approach to effective NVUGIB management is tailored to individual clinical scenarios to optimize patient outcomes.
ABSTRACT
Purpose@#With the revision of the Organ and Transplantation Act in 2018, the hand has become legal as an area of transplantable organs in Korea. In January 2021, the first hand allotransplantation since legalization was successfully performed, and we have performed a total of three successful hand transplantation since then. By comparing and incorporating our experiences, this study aimed to provide a comprehensive reconstructive solution for hand amputation in Korea. @*Materials and Methods@#Recipients were selected through a structured preoperative evaluation, and hand transplantations were performed at the distal forearm level. Postoperatively, patients were treated with three-drug immunosuppressive regimen, and functional outcomes were monitored. @*Results@#The hand transplantations were performed without intraoperative complications. All patients had partial skin necrosis and underwent additional surgical procedures in 2 months after transplantation. After additional operations, no further severe complications were observed. Also, patients developed acute rejection within 3 months of surgery, but all resolved within 2 weeks after steroid pulse therapy. Motor and sensory function improved dramatically, and patients were very satisfied with the appearance and function of their transplanted hands. @*Conclusion@#Hand transplantation is a viable reconstructive option, and patients have shown positive functional and psychological outcomes. Although this study has limitations, such as the small number of patients and short follow-up period, we should focus on continued recovery of hand function, and be careful not to develop side effects from immunosuppressive drugs. Through the present study, we will continue to strive for a bright future regarding hand transplantation in Korea.
ABSTRACT
We would like to introduce domestic subscribers of the Korean Journal of Blood Transfusion to the important aspects to be considered while selecting a reference allele and reporting a new allele candidate. ABO*A1.02 has only a single nucleotide substitution of c.467C>T in ABO*A1.01, and when ABO*A1.01 is used as the reference allele, the ABO*AW.10 allele should be marked as having both c.467C>T and c.784G>A variants. Unfortunately, it has not been modified as such in the ISBT database. For this reason, in the journal Transfusion (2020), the official journal of the Association for the Advancement of Blood Biotherapies, there was a report of a new allele with c.467C>T and c.784G>A variants. Cases of ABO*AW.10 allele with a weak A phenotype are not uncommon in Koreans, and it is necessary to accurately mark the reference allele. The blood type A reference allele of the International Society of Blood Transfusion (ISBT) database currently used for ABO alleles reporting is based on ABO*A1.01. Therefore, it should be considered that the ABO*AW.10 allele has both the c.467C>T and c.784G>A variants together.
ABSTRACT
Background@#Transgender and intersex populations have long remained under-documented in South Korea, largely due to the absence of comprehensive epidemiological data. With increasing societal acknowledgment, there's an urgent need to understand the demographics and health challenges faced by these communities. @*Methods@#This retrospective, large-scale data study included people who received the F64 codes from the Korean Health Insurance Review & Assessment Service between January 2007 and December 2021. Demographics, gender-affirmative treatments, and psychiatric related medications were examined. @*Results@#Between 2007 and 2021, 8,602 patients were diagnosed with “gender identity disorder” and 45 with “intersex.” A steadily increasing annual prevalence was observed, peaking at 986 cases in 2021. The majority (79.8%) were aged between 10 and 30. Nearly half (53.2%) exhibited mental and behavioral disorders. Two-thirds had been prescribed anxiolytics or sedatives either before or after diagnosis. Merely 12.1% received hormone therapy covered by health insurance. @*Conclusion@#This is the first large-scale study highlighting the demographics and clinical characteristics of the transgender and intersex populations in Korea. The study reveals a consistent growth of these communities over the past 15 years, with a significant proportion under 30 years of age facing mental and behavioral challenges. Findings underscore the need for targeted healthcare interventions, early psychological support, and comprehensive insurance coverage tailored to the specific needs of these individuals in Korea.
ABSTRACT
Background@#As rhinoplasty techniques have become more complex, surgeons often need more than what septal or conchal cartilage can provide. While costal cartilage became more popular for that reason, some surgeons are still uncomfortable with its invasiveness and donor site morbidity. Here, we used lyophilized allogeneic costal cartilage for septorhinoplasty and investigated its safety and usefulness. @*Methods@#The costal cartilage was harvested from a cadaveric donor and treated via multiple steps, including defatting and lyophilization, to remove all viable cells and antigenicity. The cartilage was then stored at room temperature and rehydrated 24 hours before use. Lyophilized cartilage allografts were used in 20 patients. Three types of septal graft were performed — spreader, batten, and extension — to correct septal or columellar deviation and enhance the nasal tip. @*Results@#The mean follow-up period was 4.3 years. In all cases, the graft successfully met the rhinoplasty purpose. No significant deformation was detected in any of the patients. Although warping was observed in one patient (5%), there was no case of clinical infection, extrusion, or graft removal and no revisional surgery for an unfavorable aesthetic result. @*Conclusions@#Lyophilized allogeneic cartilage was used for septorhinoplasty very safely and effectively. It can be carved into any shape and has all other properties required for perfectly replacing autologous costal cartilage. The main advantage of cartilage allografts is a limitless supply of high-quality cartilage without donor site morbidity. The disadvantages include the need for special facilities and manpower and extra covering cost.
ABSTRACT
Background@#Disruption of the rotator cuff muscles compromises concavity compression force, which leads to superior migration of the humeral head and loss of stability. A novel idea of using the magnetic force to achieve shoulder stabilization in massive rotator cuff tears (MRCTs) was considered because the magnets can stabilize two separate entities with an attraction force. This study aimed to investigate the biomechanical effect of the magnetic force on shoulder stabilization in MRCTs. @*Methods@#Seven fresh frozen cadaveric specimens were used with a customized shoulder testing system. Three testing conditions were set up: condition 1, intact rotator cuff without magnets; condition 2, an MRCT without magnets; condition 3, an MRCT with magnets. For each condition, anterior-posterior translation, superior translation, superior migration, and subacromial contact pressure were measured at 0°, 30°, and 60° of abduction. The abduction capability of condition 2 was compared with that of condition 3. @*Results@#The anterior-posterior and superior translations increased in condition 2; however, they decreased compared to condition 2 when the magnets were applied (condition 3) in multiple test positions and loadings (p <0.05). Abduction capability improved significantly in condition 3 compared with that in condition 2, even for less deltoid loading (p < 0.05). @*Conclusions@#The magnet biomechanically played a positive role in stabilizing the shoulder joint and enabled abduction with less deltoid force in MRCTs. However, to ensure that the magnet is clinically applicable as a stabilizer for the shoulder joint, it is necessary to thoroughly verify its safety in the human body and to conduct further research on technical challenges.
ABSTRACT
Purpose@#Prior research has indicated that stroke can influence the symptoms and presentation of neurogenic bladder, with various patterns emerging, including abnormal facial and linguistic characteristics. Language patterns, in particular, can be easily recognized. In this paper, we propose a platform that accurately analyzes the voices of stroke patients with neurogenic bladder, enabling early detection and prevention of the condition. @*Methods@#In this study, we developed an artificial intelligence-based speech analysis diagnostic system to assess the risk of stroke associated with neurogenic bladder disease in elderly individuals. The proposed method involves recording the voice of a stroke patient while they speak a specific sentence, analyzing it to extract unique feature data, and then offering a voice alarm service through a mobile application. The system processes and classifies abnormalities, and issues alarm events based on analyzed voice data. @*Results@#In order to assess the performance of the software, we first obtained the validation accuracy and training accuracy from the training data. Subsequently, we applied the analysis model by inputting both abnormal and normal data and tested the outcomes. The analysis model was evaluated by processing 30 abnormal data points and 30 normal data points in real time. The results demonstrated a high test accuracy of 98.7% for normal data and 99.6% for abnormal data. @*Conclusions@#Patients with neurogenic bladder due to stroke experience long-term consequences, such as physical and cognitive impairments, even when they receive prompt medical attention and treatment. As chronic diseases become increasingly prevalent in our aging society, it is essential to investigate digital treatments for conditions like stroke that lead to significant sequelae. This artificial intelligence-based healthcare convergence medical device aims to provide patients with timely and safe medical care through mobile services, ultimately reducing national social costs.
ABSTRACT
Objective@#Chronic low back pain (LBP) is a huge social burden, and optimal exercise therapies for chronic LBP patients are continuously being studied. To evaluate the effects of digital intervention on pain and disability in patients with chronic LBP, we performed a prospective cohort study. Method: From February 2020 to January 2021, 25 patients with chronic LBP were recruited. Digital intervention contains education contents and video demonstration for individually prescribed exercise. The exercise prescription was renewed every 4 weeks according to subjects’ condition and accomplishment of exercise. This intervention was performed for more than 30 weeks. The pain intensity was assessed using a numeric rating scale (NRS) while their degree of disability was assessed using the Roland-Morris Disability Questionnaire (RMDQ). The pain intensity and disability was evaluated at short term (8∼20 weeks) and long term (30 weeks). @*Results@#As a result, pain intensity (NRS) decreased significantly over the short term and long term (p<0.05). However, pain related disability (RMDQ score) did not change significantly over the follow-up period (p=0.554). @*Conclusion@#Our findings indicate that online-based digital intervention reduced the intensity of chronic LBP. Further research is needed to identify methods to cost-effectively and consistently manage chronic LBP.
ABSTRACT
Background@#There are no clear guidelines to determine whether to perform D1 or D1+ lymph node dissection in early gastric cancer (EGC). This study aimed to develop a nomogram for estimating the risk of extraperigastric lymph node metastasis (LNM). @*Materials and Methods@#Between 2009 and 2019, a total of 4,482 patients with pathologically confirmed T1 disease at 6 affiliated hospitals were included in this study. The basic clinicopathological characteristics of the positive and negative extraperigastric LNM groups were compared. The possible risk factors were evaluated using univariate and multivariate analyses. Based on these results, a risk prediction model was developed. A nomogram predicting extraperigastric LNM was used for internal validation. @*Results@#Multivariate analyses showed that tumor size (cut-off value 3.0 cm, odds ratio [OR]=1.886, P=0.030), tumor depth (OR=1.853 for tumors with sm2 and sm3 invasion, P=0.010), cross-sectional location (OR=0.490 for tumors located on the greater curvature, P=0.0303), differentiation (OR=0.584 for differentiated tumors, P=0.0070), and lymphovascular invasion (OR=11.125, P<0.001) are possible risk factors for extraperigastric LNM. An equation for estimating the risk of extraperigastric LNM was derived from these risk factors. The equation was internally validated by comparing the actual metastatic rate with the predicted rate, which showed good agreement. @*Conclusions@#A nomogram for estimating the risk of extraperigastric LNM in EGC was successfully developed. Although there are some limitations to applying this model because it was developed based on pathological data, it can be optimally adapted for patients who require curative gastrectomy after endoscopic submucosal dissection.
ABSTRACT
Background@#The model for end-stage liver disease 3.0 (MELD3.0) is expected to address the flaws of the current allocation system for deceased donor liver transplantation (DDLT). We aimed to validate MELD3.0 in the Korean population where living donor liver transplantation is predominant due to organ shortages. @*Methods@#Korean large-volume single-centric waitlist data were merged with the Korean Network for Organ Sharing (KONOS) data. The 90-day mortality was compared between MELD and MELD3.0 using the C-index in 2,353 eligible patients registered for liver transplantation. Patient numbers and outcomes were compared based on changes in KONOS-MELD categorization using MELD3.0. Possible gains in MELD points and reduced waitlist mortality were analyzed. @*Results@#MELD3.0 performed better than MELD (C-index 0.893 for MELD3.0 vs. 0.889 for MELD). When stratified according to the KONOS-MELD categories, 15.9% of the total patients and 35.2% of the deceased patients were up-categorized using MELD3.0 versus MELD categories. The mean gain of MELD points was higher in women (2.6 ± 2.1) than men (2.1 ± 1.9, P < 0.001), and higher in patients with severe ascites (3.3 ± 1.8) than in controls (1.9 ± 1.8, P< 0.001); however, this trend was not significant when the MELD score was higher than 30. When the possible increase in DDLT chance was calculated via up-categorizing using MELD3.0, reducible waitlist mortality was 2.7%. @*Conclusion@#MELD3.0 could predict better waitlist mortality than MELD; however, the merit for women and patients with severe ascites is uncertain, and reduced waitlist mortality from implementing MELD3.0 is limited in regions suffering from organ shortage, as in Korea.
ABSTRACT
Various symptomatic complaints, including dysphagia, have been reported by patients with whiplash injury, which greatly impacts their life. There are few reports on the treatment and progression of dysphagia following whiplash injuries. This case report describes a patient who presented with delayed dysphagia after a whiplash injury. A 37-year-old female visited the Department of Rehabilitation Medicine of our institution and presented with delayed dysphagia one year after a traffic accident. At the time of the accident, the patient was diagnosed with a whiplash injury and had no symptoms of dysphagia. A videofluoroscopic swallowing study revealed decreased laryngeal elevation and impaired upper esophageal sphincter opening in the pharyngeal phase. The Penetration-Aspiration Scale score was 3 for pureed food and 7 for liquid food. Laryngeal needle electromyography showed abnormal spontaneous activity in both cricothyroid muscles. The patient underwent swallowing rehabilitation for oropharyngeal dysphagia. There were recurrences of improvement and deterioration during the treatment period. However, after five months, problems related to swallowing improved until there were no complaints. Our study indicates a differentiated treatment approach and the importance of continuous rehabilitation for dysphagia after a whiplash injury.
ABSTRACT
Neuro-Behcet’s disease (NBD) is defined as a combination of neurologic symptoms and/or signs in a patient with Behcet’s disease. A 38-year-old woman was admitted due to sensory aphasia. She had past medical history of generalized tonic-clonic seizure, retinal vasculitis, oral ulcer and cerebral vasculitis. Brain magnetic resonance imaging showed broad lesion in the left parieto-occipital lobe. Brain biopsy was performed to differentiate between central nervous system lymphoma and NBD. We report a rare case of NBD with extensive involvement of cerebral parenchyma.
ABSTRACT
Background@#To evaluate the safety and effectiveness of empagliflozin in routine clinical settings, we collected and assessed the clinical profiles of Korean patients with type 2 diabetes mellitus. @*Methods@#This was a post-marketing surveillance study of empagliflozin 10 and 25 mg. Information on adverse events and adverse drug reactions (ADRs) was collected as safety data sets. Available effectiveness outcomes, including glycosylated hemoglobin (HbA1c) level, fasting plasma glucose, body weight, and blood pressure, were assessed. @*Results@#The incidence rate of ADRs was 5.14% in the safety dataset (n=3,231). Pollakiuria, pruritis genital, and weight loss were the most common ADRs. ADRs of special interest accounted for only 1.18%, and there were no serious events that led to mortality or hospitalization. In the effectiveness data set (n=2,567), empagliflozin significantly reduced the mean HbA1c level and body weight during the study period by –0.68%±1.39% and –1.91±3.37 kg (both P<0.0001), respectively. In addition, shorter disease duration, absence of dyslipidemia, and higher baseline HbA1c levels were identified as the clinical features characteristic of a “responder” to empagliflozin therapy. @*Conclusion@#Empagliflozin is a safe and potent glucose-lowering drug in routine use among Korean patients with type 2 diabetes mellitus. It is expected to have better glycemic efficacy in Korean patients with poorly controlled type 2 diabetes mellitus.
