ABSTRACT

Background@#At the end of 2014, we implemented an online video to inform patients of the entire process from admission to rehabilitation after total hip arthroplasty (THA). In this study, we investigated the effectiveness of online video instruction in THA patients. @*Methods@#Electronic medical records of 184 patients undergoing THA in 2014 (pre-video group) and 182 patients in 2015 (post-video group) were reviewed. We compared 1) the time to start wheelchair ambulation, 2) walker or crutch ambulation, 3) the length of hospital stay, 4) postoperative satisfaction using visual analogue scale (0–10 points), and 5) modified Harris Hip Score (mHHS) at postoperative 6 weeks. @*Results@#In the post-video group, the time to start wheelchair ambulation (1.8 ± 0.6 vs. 2.4 ± 3.2 days, P = 0.021) and walker/crutch ambulation were faster (2.9 ± 1.2 vs. 3.8 ± 1.0 days, P = 0.016), and the hospital stay was shorter (8.2 ± 4.7 vs. 9.9 ± 7.8 days, P = 0.001) compared to the pre-video group. The visual analogue scale for satisfaction (7.84 ± 1.62 vs. 7.68 ± 1.85 points) and mHHS (89.59 ± 9.47 vs. 89.58 ± 8.59) were similar. @*Conclusion@#Online video instruction is an effective tool to expedite ambulation and reduce the hospital stay without compromising the clinical outcome and postoperative complications after THA.

ABSTRACT

Background@#The objective of this study was to investigate the trend of self-injurious behavior (SIB) among persons who were directly impacted by coronavirus disease 2019 (COVID-19), especially those with pre-existing mental disorders. @*Methods@#Using the National Health Insurance Service-COVID-19 database cohort, the monthly SIB rate was calculated by COVID-19 subgroups (i.e., positive for COVID-19 test, negative for COVID-19 test, and non-COVID-19 test [control]). In addition, moderated regression analysis was utilized to examine the statistical difference of SIB (suicide attempt and non-suicidal self-injury using ICD-10 code) trend between COVID-19 subgroups and with and without pre-existing mental disorder. @*Results@#A total of 328,373 persons were included in the cohort study. Of these, 212,678 had been tested for COVID-19, and 7,713 of them were confirmed positive. During the pandemic peak, the “negative for COVID-19” group showed a large increase (P = 0.003) in SIB rates compared to the control group, the “positive for COVID-19” group showed a decreasing trend, but not significant (P = 0.314). Among those who were tested for COVID-19, those with pre-existing mental disorders showed an increasing trend of SIB compared to those without pre-existing mental disorders, however statistically insignificant (P= 0.137). @*Conclusion@#Our results suggest that people who are tested for COVID-19 are at a high risk of SIB during the peak COVID-19 pandemic. Therefore, screening for suicide risk and psychological interventions is needed for these high-risk groups.

ABSTRACT

Childhood hypertension (HTN) has become a significant public health issue because of the increased risk of cardiovascular disease in adulthood. However, childhood HTN is underrecognized and underdiagnosed in clinical practice. The European Society of Hypertension in 2016 and the American Academy of Pediatrics (AAP) in 2017 published updated guidelines for the screening, prevention, and management of pediatric HTN. There were notable differences between the two guidelines as well as many similarities. The updated AAP guidelines have clarified and simplified the recommendations for screening, diagnosis, and treatment of childhood HTN based on current evidence. This review highlights the important developments in both guidelines, focusing on recent advances in the classification and treatment of childhood HTN.

ABSTRACT

Purpose@#The purpose of this study is to investigate the factors influencing oncology unit nurses’ pain management of cancer patients. @*Methods@#This study was a designed descriptive correlation study. The participants of this study were nurses working in an oncology unit at a university hospital. A total of 135 nurses participated and data were collected between October 10 and October 31, 2018. Measures used for this study assessed nurses’ knowledge of cancer pain management, compassion competence, and the performance of cancer pain management. The data were analyzed using independent t-test, ANOVA, Pearson’s correlation coefficient, and multiple linear regression analysis. @*Results@#Performance of cancer pain management was significantly correlated with compassion competence (r=0.37, p<.001) and difference according to the experience of cancer by the participants or family members (t=2.22, p=.028). Performance of cancer pain management was influenced by compassion competence (β=.36,p<.001) and the experience of cancer by the participants or family members (β=.17, p=.041). The explanatory power of this model was 14.4%. @*Conclusion@#These results suggest the need for cancer pain management education based on compassion empowerment. The findings shows that continuous cancer pain management education is required in consideration of the oncology nurses’ career and work characteristics.

ABSTRACT

Background@#Liver fibrosis is defined as the accumulation of the extracellular matrix and scar formation. The receptor for advanced glycation end products (RAGE) has been demonstrated to participate in fibrogenesis. S100B is a ligand of RAGE and exerts extracellular functions by inducing a series of signal transduction cascades. However, the involvement of S100B and RAGE in cholestasis-induced liver fibrosis remains unclear. In this study, we investigated S100B and RAGE expression during liver fibrosis in mice that underwent common bile duct ligation (BDL). @*Methods@#BDL was performed in 10-week-old male C57BL/6J mice with sham control (n = 26) and BDL (n = 26) groups. Expression levels of S100B, RAGE and fibrotic markers in the livers from both groups at week 1 and 3 after BDL were examined by western blot and quantitative real-time reverse transcription polymerase chain reaction analysis. Liver fibrotic changes were examined by histological and ultrastructural analysis. @*Results@#Histological staining with Sirius Red and the evaluation of the messenger RNA expression of fibrotic markers showed noticeable periportal fibrosis and bile duct proliferation. S100B was mainly present in bile duct epithelial cells, and its expression was upregulated in proportion to the ductular reaction during fibrogenesis by BDL. RAGE expression was also increased, and interestingly, triple immunofluorescence staining and transmission electron microscopy showed that both S100B and RAGE were expressed in proliferating bile duct epithelial cells and activated hepatic stellate cells (HSCs) of the BDL livers. In addition, in rat HSCs (HSC-T6), treatment with recombinant S100B protein significantly increased fibrotic markers in a dose-dependent manner, and RAGE small interfering RNA (siRNA) suppressed S100B-stimulated upregulation of fibrotic markers compared with cells treated with scramble siRNA and S100B. @*Conclusion@#These findings suggest that the increased expression of S100B and RAGE and the interaction between S100B and RAGE may play an important role in ductular reaction and liver fibrosis induced by BDL.

ABSTRACT

Objective@#Recent studies have suggested that deep-learning models can satisfactorily assist in fracture diagnosis. We aimed to evaluate the performance of two of such models in wrist fracture detection. @*Methods@#We collected image data of patients who visited with wrist trauma at the emergency department. A dataset extracted from January 2018 to May 2020 was split into training (90%) and test (10%) datasets, and two types of convolutional neural networks (i.e., DenseNet-161 and ResNet-152) were trained to detect wrist fractures. Gradient-weighted class activation mapping was used to highlight the regions of radiograph scans that contributed to the decision of the model. Performance of the convolutional neural network models was evaluated using the area under the receiver operating characteristic curve. @*Results@#For model training, we used 4,551 radiographs from 798 patients and 4,443 radiographs from 1,481 patients with and without fractures, respectively. The remaining 10% (300 radiographs from 100 patients with fractures and 690 radiographs from 230 patients without fractures) was used as a test dataset. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of DenseNet-161 and ResNet-152 in the test dataset were 90.3%, 90.3%, 80.3%, 95.6%, and 90.3% and 88.6%, 88.4%, 76.9%, 94.7%, and 88.5%, respectively. The area under the receiver operating characteristic curves of DenseNet-161 and ResNet-152 for wrist fracture detection were 0.962 and 0.947, respectively. @*Conclusion@#We demonstrated that DenseNet-161 and ResNet-152 models could help detect wrist fractures in the emergency room with satisfactory performance.

ABSTRACT

Background@#There is lack of data on admitted hemophilia patients in Korea. For this reason, this study was intended to analyze the hospitalization data of hemophilia patients in a regional Hemophilia Treatment Center (HTC) for the first time in Korea. @*Methods@#In this retrospective study, we surveyed hospitalized patients with Hemophilia A (HA) in a HTC for 14 years. Medical records of these hemophiliacs were reviewed and data regarding demographic characteristics, cause of admissions and their outcomes in each patient were obtained. In addition, the data of admitted days, type and amount of Coagulation factor concentrate (CFC) used, treatments other than CFC infusion during the admission days were also obtained from the medical record of each patient. @*Results@#A total 107 patients with hemophilia A were admitted during 14 years. Annual rate of admission of patients with HA was 8%. Mean age on admission was 29.63±19.51 years old and mean admission days were 11.28±5.46 days. Most admissions were occurred in severe and moderate hemophilia patients. The most common cause of admission was bleed control followed by surgery and other reasons. With modified WFH CFC supplementation guideline, all the bleeds were successfully controlled and all surgeries were also successfully conducted with less total CFC consumption compared to the consumed dose of other reports. @*Conclusion@#These results suggest that it is necessary to develop more specified regimens different from WFH.

ABSTRACT

OBJECTIVES@#The discontinuation of bisphosphonate (BP) treatment before tooth extraction may induce medication-related osteonecrosis of the jaw (MRONJ). Whether the long-term discontinuation of BP treatment before tooth extraction affects the risk of developing MRONJ after tooth extraction or whether extended drug holidays induce systemic side effects remains unclear. The present study assessed the incidence of MRONJ among patients who underwent tooth extraction and did not discontinue BP therapy prior to the procedure.@*MATERIALS AND METHODS@#Patients were classified according to whether or not they discontinued BP therapy before tooth extraction. Differences in the incidence of MRONJ after tooth extraction were compared between the two groups using the chi-squared test.@*RESULTS@#The BP-continuation (BPC) and BP-discontinuation (BPDC) groups included 179 and 286 patients, respectively. One patient in the BPC group and no patients in the BPDC group developed MRONJ (P=0.385). The patients in the BPDC group stopped receiving BP therapy at a mean of 39.0±35.5 months prior to tooth extraction.@*CONCLUSION@#The possibility of pre-existing MRONJ in the extraction area must be considered during the extraction procedure. Routine discontinuation of BP medications for several months before the extraction procedure should be carefully considered, as evidence of its efficacy in reducing the development of post-extraction MRONJ is limited.

ABSTRACT

The progression of aging and the increase in musculoskeletal diseases have led to an increase in invasive treatment methods, including various surgical methods, but conservative treatment should be attempted before surgical treatment in musculoskeletal diseases. Medication for pain control, such as acetaminophen, non-steroidal anti-inflammatory drugs, steroid, opioids, antidepressants, etc., is one of the most popular methods for pain control. If the pain receptors on peripheral organ are stimulated, pain is transmitted to the brain by the ascending pathway, and the brain then secretes endogenous opioids, such as endorphin, by the descending pathway for pain control. Opioids are substances that act on the opioid receptors, and there are three receptors for opioids. The affinity for each receptor varies according to the tissue and the patient's systemic status. Antidepressants work on the synapses in the central nervous system and its main mechanism is regulation of the ascending pathway. This is mainly effective in chronic pain and neuropathic pain, which is similar in effectiveness to opioids. This review focuses on the effectiveness, method of use, and side effects of opioids and antidepressants.

ABSTRACT

OBJECTIVE@#To determine the effects of Hydrangeae Dulcis Folium (EHDF) on physical stress, changes in the whole-body cortisol level and behaviour in zebrafish (Danio rerio).@*METHODS@#One hundred and seventy-four fish were randomly divided into 4 [adrenocorticotropin hormone (ACTH) challenge test: 4 fish per group] or 6 groups (behavioural test: 10-12 fish per group, whole-body cortisol: 4 fish per group). Net handling stress (NHS) was used to induce physical stress. Fish were treated with vehicle or EHDF (5-20 mg/L) for 6 min before they were exposed to stress. And then, fish were sacrificed for collecting body fluid from whole-body or conducted behavioural tests, including novel tank test and open field test, and were evaluated to observe anxiety-like behaviours and locomotion. In addition, to elucidate the mode of action of the anti-stress effects of EHDF, ACTH (0.2 IU/g, i.p.) challenge test was performed.@*RESULTS@#The increased anxiety-like behaviours in novel tank test and open field test under stress were prevented by treatment with EHDF at 5-20 mg/L (P <0.05). Moreover, compared with the unstressed group, which was not treated with NHS, the whole-body cortisol level was significantly increased by treatment with NHS (P <0.05). Compared with the NHS-treated stressed control group, pre-treatment with EHDF at concentrations of 5-20 mg/L for 6 min significantly prevented the NHS-increased whole-body cortisol level (<0.05). In addition, ACTH challenge test showed that EHDF completely blocked the effects of ACTH on cortisol secretion (P <0.05).@*CONCLUSION@#EHDF may be a good antistress candidate and its mechanism of action may be related to its positive effects on cortisol release.

ABSTRACT

Neurofibromatosis type 1 (NF1) is a common autosomal-dominant disorder. Vasculopathies associated with NF1 are rare and can cause aneurysms, stenoses, and arteriovenous malformations. Aneurysms may rupture spontaneously, which could be fatal. Spontaneous mesenteric hemorrhage due to rupture of an inferior mesenteric artery aneurysm associated with NF1 has rarely been reported. Herein, we report a case of spontaneous rupture of a fusiform aneurysm in the superior rectal artery in a 56-year-old woman with NF1 who was successfully treated with transcatheter arterial embolization.

ABSTRACT

Duodenal varices can develop in patients with portal hypertension secondary to liver cirrhosis. Although upper gastrointestinal bleeding is often severe and fatal, the definite treatment or guideline has not been established. Although endoscopy is the primary therapeutic modality, the use of radiologic interventions, such as transjugular intrahepatic portosystemic shunt, balloon or vascular plug-assisted retrograde transvenous obliteration, and percutaneous transhepatic variceal obliteration, can be considered alternative treatment methods for duodenal varices. Herein, we report a case of duodenal varix in a patient with poor hepatic functional reserve and vascular anatomy, which are contraindications for an occlusion balloon or a vascular plug, successfully treated with coil-assisted retrograde transvenous obliteration.

ABSTRACT

PURPOSE: To evaluate the efficacy of antibiotic-loaded cement spacers (ALCSs) for the treatment of diabetic foot infections with osteomyelitis as a salvage procedure and to analyze the risk factors of treatment failure. MATERIALS AND METHODS: This study reviewed retrospectively 39 cases of diabetic foot infections with osteomyelitis who underwent surgical treatment from 2009 to 2017. The mean age and follow-up period were 62±13 years and 19.2±23.3 months, respectively. Wounds were graded using the Wagner and Strauss classification. X-ray, magnetic resonance imaging (or bone scan) and deep tissue cultures were taken preoperatively to diagnose osteomyelitis. The ankle-brachial index, toe-brachial index (TBI), and current perception threshold were checked. Lower extremity angiography was performed and if necessary, percutaneous transluminal angioplasty was conducted preoperatively. As a surgical treatment, meticulous debridement, bone curettage, and ALCS placement were employed in all cases. Between six and eight weeks after surgery, ALCS removal and autogenous iliac bone graft were performed. The treatment was considered successful if the wounds had healed completely within three months without signs of infection and no additional amputation within six months. RESULTS: The treatment success rate was 82.1% (n=32); 12.8% (n=5) required additional amputation and 5.1% (n=2) showed delayed wound healing. Bacterial growth was confirmed in 82.1% (n=32) with methicillin-resistant Staphylococcus aureus being the most commonly identified strain (23.1%, n=9). The lesions were divided anatomically into four groups; the largest number was the toes: (1) toes (41.0%, n=16), (2) metatarsals (35.9%, n=14), (3) midfoot (5.1%, n=2), and (4) hindfoot (17.9%, n=7). A significant difference in the Strauss wound score and TBI was observed between the treatment success group and failure group. CONCLUSION: The insertion of ALCSs can be a useful treatment option in diabetic foot infections with osteomyelitis. Low scores in the Strauss classification and low TBI are risk factors of treatment failure.

ABSTRACT

Fibroma of the tendon sheath (FTS) was initially described in 1936 by Geschickter and Copeland as a benign firmed soft tissue tumor that is rare and less common than another soft tissue tumors, especially giant cell tumors (GCT) of the tendon sheath. The common distinct feature is a slow-growing least painful rare entity arising from the tendon or tendon sheath. FTS is detected mostly in the fingers, hands and wrists but less commonly in the foot. Very few cases of FTS have been described arising from a flexor tendon of the foot. This article describes a 51-year-old patient with FTS that developed in the extensor tendon of the foot, which is the only known FTS to form in this area. Heterogeneous low signal intensity in both the T1- and T2-weighted images was observed in magnetic resonance imaging. The lesion was excised completely by open surgery. Histologically, it showed randomly arranged, fibroblast-like spindle cells in dense fibrous tissue and had insufficient hemosiderin-laden macrophages that are typical for GCT.

ABSTRACT

PURPOSE: To evaluate the efficiency of the electronic foot function index (eFFI) through a prospective, random based, multi-institutional study. MATERIALS AND METHODS: The study included 227 patients ranging in age from 20 to 79 years, visited for surgery in different 15 institutes, and agreed to volunteer. The patients were assigned randomly into a paper-based evaluated group (n=113) and tablet-based evaluated group (n=114). The evaluation was done on the day of hospital admission and the method was changed on the second day of surgery and re-evaluated. PADAS 2.0 (https://www.proscore.kr) was used as an electronic evaluation program. RESULTS: There were no differences in age and sex in both groups. The intraclass correlation coefficient (ICC) evaluation revealed an eFFI ICC of 0.924, showing that both results were similar. The evaluation time was shorter in the tablet-based group than the paper-based group (paper vs tablet, 3.7±3.8 vs 2.3±1.3 minutes). Thirty-nine patients (17.2%) preferred to use paper and 131 patients (57.7%) preferred the tablet. Fifty-seven patients (25.1%) found both ways to be acceptable. CONCLUSION: eFFI through tablet devices appears to be more constant than the paper-based program. In addition, it required a shorter amount of time and the patients tended to prefer the tablet-based program. Overall, tablet and cloud system can be beneficial to a clinical study.
