RESUMEN
BACKGROUND: The hyperaemic stenosis resistance (HSR) index was introduced to provide a more comprehensive indicator of the haemodynamic severity of a coronary lesion. HSR combines both the pressure drop across a lesion and the flow through it. As such, HSR overcomes the limitations of the more traditional fractional flow reserve (FFR) or coronary flow reserve (CFR) indices. AIMS: We aimed to identify the diagnostic and prognostic value of HSR and evaluate the clinical implications. METHODS: Patients with chronic coronary syndromes (CCS) and obstructive coronary artery disease were selected from the multicentre ILIAS Registry. For this study, only patients with combined Doppler flow and pressure measurements were included. RESULTS: A total of 853 patients with 1,107 vessels were included. HSR more accurately identified the presence of inducible ischaemia compared to FFR and CFR (area under the curve 0.71 vs 0.66 and 0.62, respectively; p<0.005 for both). An abnormal HSR measurement was an independent and important predictor of target vessel failure at 5-year follow-up (hazard ratio 3.80, 95% confidence interval: 2.12-6.73; p<0.005). In vessels deferred from revascularisation, HSR seems to identify more accurately those vessels that may benefit from revascularisation rather than FFR and/or CFR. CONCLUSIONS: The present study affirms the theoretical advantages of the HSR index for the detection of ischaemia-Âinducing coronary lesions in a large CCS population.

Introduction: The platelet-to-lymphocyte ratio (PLR) is associated with the inflammatory response in various diseases. However, studies on the use of the PLR for the prognosis of elderly patients with severe trauma are lacking. In this study, we examined the relationship between the PLR and in-hospital mortality in elderly patients with severe trauma. Methods: This retrospective observational study included elderly (≥65 years) patients who were admitted for severe trauma (as defined by an Injury Severity Score [ISS] ≥ 16) between January-December 2022. We conducted multivariate analysis to assess the association between the PLR and in-hospital mortality using logistic regression of relevant covariates. We also performed receiver operating characteristic curve analysis to examine the prognostic performance of the PLR for in-hospital mortality. Results: Among the 222 patients included in the study, the in-hospital mortality rate was 19.4% (43). The PLR of non-survivors was lower than that of survivors (62.1 vs 124.5). The areas under the curve (AUC) of the Glasgow Coma Scale (GCS) score ≤12, ISS, hemoglobin level, and PLR for predicting in-hospital mortality were 0.730 (95% confidence interval [CI] 0.667-0.787), 0.771 (95% CI 0.710-0.824), 0.657 (95% CI 0.591-0.719), and 0.730 (95% CI 0.667-0.788), respectively. The AUC of the PLR was not significantly different from that of GCS score ≤12 and ISS for predicting in-hospital mortality. Multivariate analysis showed that the PLR was independently associated with in-hospital mortality (odds ratio: 0.993; 95% CI 0.987-0.999). Conclusion: Low platelet-to-lymphocyte ratio is independently associated with in-hospital mortality in elderly patients with severe trauma.

Asians typically exhibit prominent zygomas; therefore, several attempts have been made to reduce these structures to achieve a softer appearance. The intraoral approach is preferred because of its shorter surgical duration and lower invasiveness; however, it is associated with serious complications, such as nonunion. In revisional surgery, the intraoral approach poses limitations in accessing the upper part of the zygoma and the lateral orbital rim area due to its restricted operative field. Therefore, we developed an intraoral interpositional bone graft technique that enabled almost complete reconstruction. A 40-year-old woman presented with persistent depression in the left infraorbital and cheek regions after two revision operations after reduction malarplasty. Based on computed tomography (CT) scan findings, reconstruction using bone grafts was planned. Calvarial bone was harvested and divided into cortical and cancellous parts. The cortical bone was sculpted into an L-shape and inserted into the gap between the maxilla and the lower zygoma body. The hard-to-reach lateral orbital rim area was filled with cancellous bone without fixation. Follow-up CT scans showed that the cortical bone grafts were well-maintained and stabilized with titanium plates, while the cancellous bone had undergone significant resorption and was replaced by new bone, indicative of successful natural healing.
RESUMEN
Background@#Botulinum toxin type A is widely used to improve facial wrinkles associated with aging, and various types are available. However, the efficacy, particularly the duration of effect, varies among these types, and research on this subject is limited. This study aimed to compare the efficacy and safety of incobotulinum toxin A and abobotulinum toxin A. @*Methods@#This prospective analysis included cases of moderate to severe glabellar lines treated with either incobotulinum toxin A or abobotulinum toxin A. After a 24-week follow-up, clinical photos were taken at each visit. The severity of the glabellar lines was evaluated by three groups: the investigator, the patients, and an independent evaluator. @*Results@#The study included a total of 42 patients. When comparing the improvement rates of glabellar lines at maximum frown for both groups at the week-4 visit, which was the primary efficacy endpoint, no statistically significant difference was observed. However, the abobotulinum toxin A group demonstrated a higher improvement at the week-24 visit, as evaluated by the investigator, and this difference was statistically significant. @*Conclusions@#Overall, the abobotulinum toxin A group exhibited a higher improvement rate in the glabellar lines at the frown state. The difference in the improvement rate at the week-24 visit was 36.86%, which was statistically significant.
RESUMEN
In-stent restenosis (ISR) develops primarily due to neointimal hyperplasia. Gallic acid (GA) has anti-inflammatory, antioxidant, and cardioprotective effects. This study sought to investigate the effects of GA on neointimal hyperplasia and proliferation and migration of vascular smooth muscle cells (VSMCs) in a pig ISR model. In vitro proliferation and migration experiments were confirmed, after VSMCs were treated with plateletderived growth factor (PDGF-BB) and GA (100 µM) using a 3‑(4,5‑dimethylthiazol)‑ 2,5‑diphenyltetrazolium bromide (MTT) assay and a scratch wound assay for 24 hours and 48 hours. A bare metal stent (BMS) was implanted in the pig coronary artery to induce ISR with overdilation (1.1-1.2:1), and GA (10 mg/kg/day) was administered for 4 weeks. At the 4-week follow-up, optical coherence tomography (OCT) and histopathological analyses were performed. GA decreased the proliferation of VSMCs by PDGF-BB for 24 hours (89.24±24.56% vs. 170.04±19.98%, p<0.001) and 48 hours (124.87±7.35% vs. 187.64±4.83%, p<0.001). GA inhibited the migration of VSMCs induced by PDGF-BB for 24 hours (26.73±2.38% vs. 65.38±9.73%, p<0.001) and 48 hours (32.96±3.04% vs. 77.04±10.07%, p<0.001). Using OCT, % neointimal hyperplasia was shown to have significantly decreased in the GA group compared with control vehicle group (28.25± 10.07% vs. 37.60±10.84%, p<0.001). GA effectively reduced neointimal hyperplasia by inhibiting the proliferation and migration of VSMCs in a pig ISR model. GA could be a potential treatment strategy for reducing ISR after stent implantation.
RESUMEN
Objective@#: Recently, robotic-assisted spine surgery (RASS) has been considered a minimally invasive and relatively accurate method. In total, 495 robotic-assisted pedicle screw fixation (RAPSF) procedures were attempted on 100 patients during a 14-month period. The current study aimed to analyze the accuracy, potential risk factors, and learning curve of RAPSF. @*Methods@#: This retrospective study evaluated the position of RAPSF using the Gertzbein and Robbins scale (GRS). The accuracy was analyzed using the ratio of the clinically acceptable group (GRS grades A and B), the dissatisfying group (GRS grades C, D, and E), and the Surgical Evaluation Assistant program. The RAPSF was divided into the no-breached group (GRS grade A) and breached group (GRS grades B, C, D, and E), and the potential risk factors of RAPSF were evaluated. The learning curve was analyzed by changes in robot-used time per screw and the occurrence tendency of breached and failed screws according to case accumulation. @*Results@#: The clinically acceptable group in RAPSF was 98.12%. In the analysis using the Surgical Evaluation Assistant program, the tip offset was 2.37±1.89 mm, the tail offset was 3.09±1.90 mm, and the angular offset was 3.72°±2.72°. In the analysis of potential risk factors, the difference in screw fixation level (p=0.009) and segmental distance between the tracker and the instrumented level (p=0.001) between the no-breached and breached group were statistically significant, but not for the other factors. The mean difference between the no-breach and breach groups was statistically significant in terms of pedicle width (p<0.001) and tail offset (p=0.042). In the learning curve analysis, the occurrence of breached and failed screws and the robot-used time per screw screws showed a significant decreasing trend. @*Conclusion@#: In the current study, RAPSF was highly accurate and the specific potential risk factors were not identified. However, pedicle width was presumed to be related to breached screw. Meanwhile, the robot-used time per screw and the incidence of breached and failed screws decreased with the learning curve.
RESUMEN
Objective@#: Markers of neuroinflammation during ischemic stroke are well characterized, but additional markers of neural damage are lacking. The study identified associations of behavioral disorders after stroke with histologic neural damage and molecular biological change. @*Methods@#: Eight-week-old, 25 g male mice of the C57BL/6J strain were subjected to middle cerebral artery occlusion (MCAO) to induce ischemic stroke. The control group was a healthy wild type (WT), and the experimental group were designed as a low severity MCAO1 and a high severity MCAO2 based on post-stroke neurological scoring. All groups underwent behavioral tests, realtime polymerase chain reaction, triphenyltetrazolium chloride (TTC) staining and Hematoxylin and Eosin staining. One-way analysis of variance was used to analyze statistical significance between groups. @*Results@#: In TTC staining, MCAO1 showed 29.02% and MCAO2 showed 38.94% infarct volume (p<0.0001). The pro-inflammatory cytokine interleukin (IL)-1β was most highly expressed in MCAO2 (WT 0.44 vs. MCAO1 2.69 vs. MCAO2 5.02, p<0.0001). From the distance to target in the Barnes maze test, WT had a distance of 178 cm, MCAO1 had a distance of 276 cm, and MCAO2 had a distance of 1051 (p=0.0015). The latency to target was 13.3 seconds for WT, 27.9 seconds for MCAO1, and 87.9 seconds for MCAO2 (p=0.0007). Prospero homeobox 1 (Prox1) was most highly expressed in MCAO2 (p=0.0004). Doublecortin (Dcx) was most highly expressed in MCAO2 (p<0.0001). @*Conclusion@#: The study demonstrated that histological damage to neural cells and changes in brain mRNA expression were associated with behavioral impairment after ischemic stroke. Prox1 and Dcx may be biomarkers of neural damage associated with long-term cognitive decline, and increased expression at the mRNA level was consistent with neural damage and long-term cognitive dysfunction.
RESUMEN
Background@#/Aim: Atezolizumab plus bevacizumab and lenvatinib are currently available as first-line therapy for the treatment of unresectable hepatocellular carcinoma (HCC). However, comparative efficacy studies are still limited. This study aimed to investigate the effectiveness of these treatments in HCC patients with portal vein tumor thrombosis (PVTT). @*Methods@#We retrospectively included patients who received either atezolizumab plus bevacizumab or lenvatinib as first-line systemic therapy for HCC with PVTT. Primary endpoint was overall survival (OS), and secondary endpoints included progressionfree survival (PFS) and disease control rate (DCR) determined by response evaluation criteria in solid tumors, version 1.1. @*Results@#A total of 52 patients were included: 30 received atezolizumab plus bevacizumab and 22 received lenvatinib. The median follow-up duration was 6.4 months (interquartile range, 3.9-9.8). The median OS was 10.8 months (95% confidence interval [CI], 5.7 to not estimated) with atezolizumab plus bevacizumab and 5.8 months (95% CI, 4.8 to not estimated) with lenvatinib (P=0.26 by log-rank test). There was no statistically significant difference in OS (adjusted hazard ratio [aHR], 0.71; 95% CI, 0.34-1.49; P=0.37). The median PFS was similar (P=0.63 by log-rank test), with 4.1 months (95% CI, 3.3-7.7) for atezolizumab plus bevacizumab and 4.3 months (95% CI, 2.6-5.8) for lenvatinib (aHR, 0.93; 95% CI, 0.51-1.69; P=0.80). HRs were similar after inverse probability treatment weighting. The DCRs were 23.3% and 18.2% in patients receiving atezolizumab plus bevacizumab and lenvatinib, respectively (P=0.74). @*Conclusion@#The effectiveness of atezolizumab plus bevacizumab and lenvatinib was comparable for the treatment of HCC with PVTT.
RESUMEN
Background@#and Purpose The accurate prediction of functional outcomes in patients with acute ischemic stroke (AIS) is crucial for informed clinical decision-making and optimal resource utilization. As such, this study aimed to construct an ensemble deep learning model that integrates multimodal imaging and clinical data to predict the 90-day functional outcomes after AIS. @*Methods@#We used data from the Korean Stroke Neuroimaging Initiative database, a prospective multicenter stroke registry to construct an ensemble model integrated individual 3D convolutional neural networks for diffusion-weighted imaging and fluid-attenuated inversion recovery (FLAIR), along with a deep neural network for clinical data, to predict 90-day functional independence after AIS using a modified Rankin Scale (mRS) of 3–6. To evaluate the performance of the ensemble model, we compared the area under the curve (AUC) of the proposed method with that of individual models trained on each modality to identify patients with AIS with an mRS score of 3–6. @*Results@#Of the 2,606 patients with AIS, 993 (38.1%) achieved an mRS score of 3–6 at 90 days post-stroke. Our model achieved AUC values of 0.830 (standard cross-validation [CV]) and 0.779 (time-based CV), which significantly outperformed the other models relying on single modalities: b-value of 1,000 s/mm2 (P<0.001), apparent diffusion coefficient map (P<0.001), FLAIR (P<0.001), and clinical data (P=0.004). @*Conclusion@#The integration of multimodal imaging and clinical data resulted in superior prediction of the 90-day functional outcomes in AIS patients compared to the use of a single data modality.
RESUMEN
Purpose@#We aimed to compare the accuracy of the intraocular lens (IOL) calculation formula using the standard keratometry (K) and total K (TK) during the femtosecond laser-assisted cataract surgery (FLACS) with a monofocal IOL with enhanced intermediate function using currently used formulas. @*Methods@#A retrospective review of 125 eyes from 125 patients who had undergone FLACS with implantation of monofocal IOL with enhanced intermediate function was conducted. The predicted refractive power was calculated using an optical biometer (IOLmaster 700) according to the K and TK in the Barrett Universal II, SRK/T, Haigis, and Holladay 2 formulas. Absolute prediction error (APE) obtained from the actual postoperative refractive outcomes and the refractive error predicted in each formula was compared one month after surgery. @*Results@#Mean APE ranged between 0.29 and 0.39 diopters (D) regardless of the calculation formula and the method of measuring corneal curvature. Significant differences were observed in the APE from the four formulas and the two keratometric measurements (p = 0.014). In a total of 125 eyes from 125 patients, the mean APE was lowest with the Barrett Universal II formula. Across all formulas, both the mean APE and the median APE tended to be lower for K than for TK, although there was no significant difference. Approximately 70% to 80% of the patients were included within 0.5 D of the refractive error across all formulas. The percentage of eyes within 0.5 D of APE outcomes was not statistically different between the K and TK data when using each formula. @*Conclusions@#Keratometric measurements considering the poster corneal curvature did not show any additional advantages when implanting the monofocal IOL with enhanced intermediate function during the FLACS.
RESUMEN
Purpose@#To evaluate the efficacy of intravitreal brolucizumab in polyp regression of treatment-naive polypoidal choroidal vasculopathy (PCV) patients and its effect on 1-year treatment outcome. @*Methods@#Medical records of 31 treatment-naive PCV patients, who received three monthly intravitreal brolucizumab injections followed by as-needed injections for at least a year, were retrospectively reviewed. Visual and anatomical outcomes were evaluated at 3, 6, and 12 months. Complete polyp regression rate and percentage change of vascular lesion and polyp area were evaluated after three monthly injections of brolucizumab. The effect of complete polyp regression and the impact of vascular lesion and polyp reduction rate on 1-year treatment outcome were also evaluated. @*Results@#In terms of visual outcome, best-corrected visual acuity significantly improved after 12-month follow-up (p < 0.001). In terms of anatomical outcome, central macular thickness (CMT) and central choroidal thickness significantly decreased after 12-month follow-up (p < 0.001). Complete polyp regression was observed in 23 patients (74.2%) after three monthly injections. Group with complete polyp regression had a higher rate of achieving dry macula at 3 months (p = 0.026) and fewer number of injections (p < 0.001) compared to the group without complete polyp regression. Higher polyp reduction rate was significantly associated with higher CMT change from baseline at 3 months (p = 0.048) while higher vascular lesion reduction rate was significantly associated with higher CMT change from baseline at 12 months (p = 0.031) and fewer number of injections (p = 0.012). @*Conclusions@#Intravitreal brolucizumab injection effectively improved visual and anatomical outcomes and achieved significant polyp regression in treatment-naive PCV patients. Complete polyp regression and the reduction rate of vascular lesion size and polyp size after loading injection significantly influence the treatment outcome of PCV patients. However, careful monitoring and preoperative warning is warranted due to occurrence of brolucizumab-related IOI.
RESUMEN
Bronchopulmonary dysplasia (BPD) and pulmonary hypertension (PH) are potentially fatal complications in prematurely born infants. Extracorporeal membrane oxygenation (ECMO) may be a life-saving option for managing infants with BPD and PH. We present 2 patients who were successfully weaned off mechanical ventilators (MVs) through the application of ECMO. The patients were transferred to our institution after receiving MV care for 8 and 10 months, respectively, for BPD and PH. We were able to remove the patients from MVs after a period of ECMO-mediated lung rest. Although more research is required to determine specific criteria for ECMO use in patients with BPD and PH, our clinical experiences may contribute to the early application of ECMO in MV-dependent patients.
RESUMEN
Cardiac tamponade (CT) is a rare but potentially lethal complication associated with central venous catheters (CVCs). We present a 6-year-old boy who developed CT after CVC insertion in the right internal jugular vein, with its tip in the inferior vena cava. Initially, he was hospitalized to a tertiary hospital with presumptive diagnoses of pneumonia and left ankle cellulitis. Three days after CVC placement, he developed CT, manifesting as recurrent episodes of hypotension and bradycardia. Once a bedside echocardiography showed CT, pericardiocentesis was performed, resulting in successful resuscitation. Pericardiocentesis revealed a milk-appearing pericardial fluid, indicating chylopericardium. The boy also underwent debridement and joint irrigation of the left ankle, which turned out to be osteomyelitis. Although CVC tips in most reported CVC-related CTs have been commonly located in the right atrium, our case featured a tip located in the inferior vena cava. Additionally, chylopericardium was likely due to the extravasation of total parenteral nutrition fluid, rather than the usual causes, such as recent thoracic surgery. Understanding the mechanisms behind chylopericardium associated with CVCs and timely pericardiocentesis is crucial for improving the outcomes.
RESUMEN
Objective@#We aimed to identify the expectations and preferences for medication and medical decision-making in patients with major psychiatric disorders. @*Methods@#A survey was conducted among patients with major psychiatric disorders who visited psychiatric outpatient clinics at 15 hospitals between 2016 and 2018 in Korea. The survey consisted of 12 questions about demographic variables and opinions on their expectations for medication, important medical decision-makers, and preferred drug type. The most preferred value in each category in the total population was identified, and differences in the preference ratio of each item among the disease groups were compared. @*Results@#A total of 707 participants were surveyed. In the total population, patients reported high efficacy (44.01%±21.44%) as the main wish for medication, themselves (37.39%±22.57%) and a doctor (35.27%±22.88%) as the main decision makers, and tablet/capsule (36.16%±30.69%) as the preferred type of drug. In the depressive disorders group, the preference ratio of high efficacy was significantly lower, and the preference ratio of a small amount was significantly higher than that of the psychotic disorder and bipolar disorder groups. The preference ratio of a doctor as an important decision maker in the bipolar disorder group was higher compared to the other groups. @*Conclusion@#This study revealed the preference for medications and showed differences among patients with psychiatric disorders. Providing personalized medicine that considers a patient’s preference for the drug may contribute to the improvement of drug compliance and outcomes.
RESUMEN
Background/Aims@#The efficacy of concurrent chemoradiotherapy (CCRT) or esophagectomy for locally advanced esophageal squamous cell carcinoma (ESCC) is unclear. This study compared the survival and recurrence of patients with locally advanced ESCC after definitive CCRT and surgery. @*Methods@#A retrospective study was conducted on patients with locally advanced ESCC who underwent CCRT or esophagectomy at Kosin University Gospel Hospital from January 2010 to December 2016. The patients’ baseline characteristics, pathology, recurrence rate, and three-year/five-year overall survival were obtained Results: This study evaluated ESCC patients with cT1-T2, N+ or cT3-T4, or N, who were treated by definitive CCRT (n=14) or esophagectomy (n=32). No significant difference was noted between the two groups, except for the location of the cancer and performance state. The respective three- and five-year overall survival rates were 30.8% and 23.1% in the CCRT group and 40.2% and 22.5% in the esophagectomy group (p=0.685). In the CCRT group, three patients (21.4%) had a complete response, and two (66.7%) had a recurrence. In the esophagectomy group, an R0 resection was achieved in 28 (87.5%) patients, and a recurrence occurred in 18 (64.3%). The median disease-free survival in the CCRT and esophagectomy groups was 14 and 17 months, respectively (p=0.882). @*Conclusions@#These results showed no significant difference in survival between the definitive CCRT and surgery as the initial treatment. Nevertheless, larger prospective studies will be needed because of the retrospective nature and small number of patients in this study.
RESUMEN
Socially assistive robots are increasingly being explored to improve the engagement of older adults and people with disability in health and well-being-related exercises. However, even if people have various physical conditions, most prior work on social robot exercise coaching systems has utilized generic, predefined feedback. The deployment of these systems still remains a challenge. In this paper, we present our work of iteratively engaging therapists and post-stroke survivors to design, develop, and evaluate a social robot exercise coaching system for personalized rehabilitation. Through interviews with therapists, we designed how this system interacts with the user and then developed an interactive social robot exercise coaching system. This system integrates a neural network model with a rule-based model to automatically monitor and assess patients' rehabilitation exercises and can be tuned with individual patient's data to generate real-time, personalized corrective feedback for improvement. With the dataset of rehabilitation exercises from 15 post-stroke survivors, we demonstrated our system significantly improves its performance to assess patients' exercises while tuning with held-out patient's data. In addition, our real-world evaluation study showed that our system can adapt to new participants and achieved 0.81 average performance to assess their exercises, which is comparable to the experts' agreement level. We further discuss the potential benefits and limitations of our system in practice.
RESUMEN
STUDY DESIGN: Retrospective Cohort. OBJECTIVE: Antiresorptive drugs are often given to minimize fracture risk for bone metastases, but data regarding optimal time or ability to reduce stereotactic body radiotherapy (SBRT)-induced fracture risk is limited. This study examines the association between antiresorptive use surrounding spinal SBRT and vertebral compression fracture (VCF) incidence to provide information regarding effectiveness and optimal timing of use. METHODS: Patients treated with SBRT for spinal metastases at a single institution between 2009-2020 were included. Kaplan-Meier analysis was used to compare cumulative incidence of VCF for those taking antiresorptive drugs pre-SBRT, post-SBRT only, and none at all. Cox proportional hazards and Fine-Gray competing risk models were used to identify additional factors associated with VCF. RESULTS: Of the 234 patients (410 vertebrae) analyzed, 49 (20.9%) were taking bisphosphonates alone, 42 (17.9%) were taking denosumab alone, and 25 (10.7%) were taking both. Kaplan-Meier analysis revealed a statistically significant lower VCF incidence for patients initiating antiresorptive drugs before SBRT compared to those taking none at all (4% vs 12% at 1 year post-SBRT, P = .045; and 4% vs 23% at 2 years, P = .008). On multivariate analysis, denosumab duration (HR: .87, P = .378) or dose (HR: 1.00, P = .644) as well as bisphosphonate duration (HR: .98, P= .739) or dose (HR: .99, P= .741) did not have statistical significance on VCF incidence. CONCLUSION: Initiating antiresorptive agents before SBRT may reduce the risk of treatment-induced VCF. Antiresorptive drugs are underutilized in patients with spine metastases and may represent a useful intervention to minimize toxicity and improve long-term outcomes.
RESUMEN
Purpose@#This study aimed to describe the desperate situation where the clinician should make decisions to further manage patients having experienced adverse drug reaction (ADR) to lamotrigine that is indicated to not easily controlled neuropsychiatric diseases. @*Methods@#A descriptive analysis was done by thoroughly reviewing medical records of patients who were reported to have ADR to lamotrigine in a regional drug-safety center between 2010 and 2018. @*Results@#Eighty-four cases of lamotrigine-related ADRs occurred in 80 patients. Skin lesions were most commonly observed in 70 cases (83.3%) and 14 cases (16.7%) had severe ADRs. Sixty-three subjects (78.8%) discontinued lamotrigine, while 17 (21.3%) continued it.At the time of discontinuation, 30.0% were prescribed aromatic antiepileptic drugs. Among 4 subjects who were eventually prescribed lamotrigine again after a period of discontinuation, 3 (75.0%) experienced its recurrence. Among patients who had taken alternative medications, the incidence of ADRs was higher in those being prescribed aromatic antiepileptic drugs than in the others being prescribed other than aromatic antiepileptic drugs (P = 0.013). Regarding the control of underlying diseases, as many as 65 (86.7%) and 68 (90.7%) failed to reach maintaining the resolved state from 6 months and 12 months after the substitution, respectively. @*Conclusion@#Patients can be easily trapped between the recurrence of ADRs and the treatment failure to a certain drug like lamotrigine, in which we can hardly find a reasonable alternative to manage them.
RESUMEN
Background@#The longstanding and common use of hyaluronic acid (HA) has driven the expanded development of various commercial HA fillers. However, differences in the components of these HA fillers lead to variations in their effect. We compared the in vivo safety and efficacy of biphasic HA (BHA) and a new monophasic HA (MHA) for improving facial wrinkles. We investigated differences in outcomes after their injection into nasolabial folds (NLFs) using the Wrinkle Severity Rating Scale (WSRS), patient satisfaction using the Global Aesthetic Improvement Scale (GAIS), and pain using a visual analog scale (VAS). We also performed a safety assessment of the two fillers. @*Methods@#This matched-pair, double-blind, randomized study compared the degree of temporal wrinkle improvement in the NLFs of 91 participants using the BHA filler versus the new MHA filler. Safety and efficacy were compared at 8 and 24 weeks. @*Results@#At 24 weeks after application, the average WSRS scores were 2.17±0.72 (BHA) and 2.07±0.71 (MHA) (P=0.034). The average GAIS scores, as measured by a treating investigator at 8 weeks and 24 weeks, were 0.94±0.76 (BHA) and 0.98±0.78 (MHA) at 8 weeks (P=0.181), and 0.44±0.64 (BHA) and 0.49±0.69 (MHA) at 24 weeks (P=0.103). The VAS pain score was 0 points at 30 minutes after filler application in both groups. @*Conclusions@#Both the BHA filler and the new MHA filler were safe and effective for improving facial wrinkles in NLFs, but the new MHA filler was more effective for the cosmetic improvement of wrinkle severity than the BHA filler.
RESUMEN
Methods@#We used 1.0-mm interval computed tomographic scan images of 100 patients (50 men and 50 women) and screw trajectory simulation software. The diameter of all screws was set at 3.5 mm, considering its common usage in real surgery. The anatomical feasibility of placing both pedicle and laminar screws on the same side was evaluated. For all feasible sides, the three-dimensional distance between the screw entry points was measured. @*Results@#In 85% of cases, both pedicle and laminar screws could be placed on both sides, allowing for the insertion of 4 screws. In 11% of cases, 2 screws could be placed on one side, while only 1 screw was feasible on the other side, resulting in the placement of 3 screws. In all 181 sides where both types of screws could be inserted, the distance between their entry points exceeded 16.1 mm, which was sufficient to prevent the collision between the screw heads. @*Conclusions@#C2 vertebra can accommodate three (11%) or four (85%) screws in 96% of cases.
