ABSTRACT

Background@#To investigate the efficacy and safety of moderate-intensity rosuvastatin/ezetimibe combination compared to highintensity rosuvastatin in high atherosclerotic cardiovascular disease (ASCVD) risk patients with type 2 diabetes mellitus (T2DM). @*Methods@#This study was a randomized, multicenter, open, parallel phase 4 study, and enrolled T2DM subjects with an estimated 10-year ASCVD risk ≥7.5%. The primary endpoint was the low-density lipoprotein cholesterol (LDL-C) change rate after 24-week rosuvastatin 10 mg/ezetimibe 10 mg treatment was non-inferior to that of rosuvastatin 20 mg. The achievement proportion of 10-year ASCVD risk <7.5% or comprehensive lipid target (LDL-C <70 mg/dL, non-high-density lipoprotein cholesterol <100 mg/dL, and apolipoprotein B <80 mg/dL) without discontinuation, and several metabolic parameters were explored as secondary endpoints. @*Results@#A hundred and six participants were assigned to each group. Both groups showed significant reduction in % change of LDL-C from baseline at week 24 (–63.90±6.89 vs. –55.44±6.85, combination vs. monotherapy, p=0.0378; respectively), but the combination treatment was superior to high-intensity monotherapy in LDL-C change (%) from baseline (least square [LS] mean difference, –8.47; 95% confidence interval, –16.44 to –0.49; p=0.0378). The combination treatment showed a higher proportion of achieved comprehensive lipid targets rather than monotherapy (85.36% vs. 62.22% in monotherapy, p=0.015). The ezetimibe combination significantly improved homeostasis model assessment of β-cell function even without A1c changes (LS mean difference, 17.13; p=0.0185). @*Conclusion@#In high ASCVD risk patients with T2DM, the combination of moderate-intensity rosuvastatin and ezetimibe was not only non-inferior but also superior to improving dyslipidemia with additional benefits compared to high-intensity rosuvastatin monotherapy.

ABSTRACT

The mentalis muscle is a paired muscle originating from the alveolar bone of the mandible. This muscle is the main target muscle for botulinum neurotoxin (BoNT) injection therapy, which aims to treat cobblestone chin caused by mentalis hyperactivity. However, a lack of knowledge on the anatomy of the mentalis muscle and the properties of BoNT can lead to side effects, such as mouth closure insufficiency and smile asymmetry due to ptosis of the lower lip after BoNT injection procedures. Therefore, we have reviewed the anatomical properties associated with BoNT injection into the mentalis muscle.An up-to-date understanding of the localization of the BoNT injection point according to mandibular anatomy leads to better injection localization into the mentalis muscle. Optimal injection sites have been provided for the mentalis muscle and a proper injection technique has been described. We have suggested optimal injection sites based on the external anatomical landmarks of the mandible. The aim of these guidelines is to maximize the effects of BoNT therapy by minimizing the deleterious effects, which can be very useful in clinical settings.

ABSTRACT

The aim of this study was to elucidate the intramuscular arborization of the teres minor muslce for effective botulinum neurotoxin injection. Twelve specimens from 6 adult Korean cadavers (3 males and 3 females, age ranging from 66 to 78 years) were used in the study. The reference line between the 2/3 point of the axillary border of the scapula (0/5), where the muscle originates ant the insertion point of the greater tubercle of the humerus (5/5). The most intramuscular neural distribution was located on 1/5–3/5 of the muscle. The tendinous portion was observed in the 3/5–5/5. The result suggests the botulinum neurotoxin should be delivered in the 1/5–3/5 area of the teres minor muscle.

ABSTRACT

The depressor anguli oris (DAO) muscle is a thin, superficial muscle located below the corner of the mouth. It is the target for botulinum neurotoxin (BoNT) injection therapy, aimed at treating drooping mouth corners. Hyperactivity of the DAO muscle can lead to a sad, tired, or angry appearance in some patients. However, it is difficult to inject BoNT into the DAO muscle because its medial border overlaps with the depressor labii inferioris and its lateral border is adjacent to the risorius, zygomaticus major, and platysma muscles. Moreover, a lack of knowledge of the anatomy of the DAO muscle and the properties of BoNT can lead to side effects, such as asymmetrical smiles. Anatomical-based injection sites were provided for the DAO muscle, and the proper injection technique was reviewed. We proposed optimal injection sites based on the external anatomical landmarks of the face. The aim of these guidelines is to standardize the procedure and maximize the effects of BoNT injections while minimizing adverse events, all by reducing the dose unit and injection points.

ABSTRACT

Background/Aims@#Daratumumab has shown an encouraging antitumor effect in patients with multiple myeloma (MM), and was known to alter the immune properties by off-targeting immunosuppressive cells. Here, we aimed to evaluate the change in absolute lymphocyte count (ALC) as a surrogate marker for predicting survival outcomes of patients treated with daratumumab. @*Methods@#Between 2018 and 2021, the medical records of patients with relapsed/refractory MM (RRMM) treated with daratumumab monotherapy at 10 centers in South Korea were reviewed. We collected the ALC data at pre-infusion (D0), day 2 after the first infusion (D2), and prior to the third cycle of daratumumab therapy (D56). @*Results@#Fifty patients who were administered at least two cycles of daratumumab were included. Overall response rate was 54.0% after two cycles of daratumumab treatment. On D2, almost all patients experienced a marked reduction in ALC. However, an increase in ALC on D56 (ALCD56) was observed in patients with non-progressive disease, whereas failure of ALC recovery was noted in those with progressive disease. Patients with ALCD56 > 700/μL (n = 39, 78.0%) had prolonged progression- free survival (PFS) and overall survival (OS) than those with ALCD56 ≤ 700/μL (median PFS: 5.8 months vs. 2.6 months, p = 0.025; median OS: 24.1 months vs. 6.1 months, p = 0.004). In addition, ALCD56 >700/μL was a significant favorable prognostic factor for PFS (hazard ratio [HR], 0.22; p = 0.003) and OS (HR, 0.23; p = 0.012). @*Conclusions@#Increase in ALC during daratumumab treatment was significantly associated with prolonged survival outcomes in patients with RRMM. The ALC value can predict clinical outcomes in patients treated with daratumumab.

ABSTRACT

Background@#Atopic dermatitis (AD) and asthma are chronic allergic diseases that affect quality of life. @*Objective@#In this study, we analyzed data from the Korea National Health and Nutrition Examination Survey (KNHANES) to determine the association between allergic diseases and number of household members living with the patient. @*Methods@#This study included 20,893 participants >19 years of age from the KNHANES (2010∼2013). Multiple logistic regression analysis was performed to evaluate the odds ratio (OR) for presence of AD or asthma according to number of household members. @*Results@#The OR of allergic diseases including AD and/or asthma increased as the number of household members decreased in the age <40 group after adjustments for age, sex, smoking status, drinking status, regular physical activity, education level, income level, and stress level (1 member: adjusted OR [aOR]=2.019, 95% confidence interval [CI]=1.256∼3.245; 2 or 3 members: aOR=1.3, 95% CI=1.031∼1.64; ≥4 members: reference). And those with an allergic disease were less likely to have a spouse and had a higher stress level compared to those without. @*Conclusion@#Based on a nationwide population-based survey, this study showed that the number of household members was significantly related to rates of AD and asthma. The prevalence of allergic diseases tended to be higher in households with fewer members.

ABSTRACT

Purpose@#The adductor pollicis muscle is frequently targeted for botulinum neurotoxin injective treatment for spasticity. However, there are no injective guidelines for delivering injection to the muscle. @*Materials and Methods@#A method known as the modified Sihler’s method was used to stain the adductor pollicis muscle in 16 specimens to reveal intramuscular neural distribution of the muscle. @*Results@#The most intramuscular neural distribution was located on 1/5 to 3/5 of the muscle regarding midline of 3rd metacarpal bone (0) to the base of the 1st proximal phalanx (5/5). The nerve entry point was mostly located on 0 to 1/5 of the muscle. @*Conclusion@#The result suggests that botulinum neurotoxin should be delivered at the middle of second metacarpal bone via deep injection.

ABSTRACT

Purpose@#Anatomical landmarks can provide vital information on the distribution of nerves in the gastrocnemius muscle. We aimed to provide an anatomical perspective on appropriate locations for botulinum neurotoxin (BoNT) injections in the medial and lateral parts of the gastrocnemius for calf shaping. @*Materials and Methods@#A modified Sihler’s method was applied to both the medial and lateral parts of the gastrocnemius muscles (16 specimens). Intramuscular neural distributions were revealed by dissecting along a transverse line crossing the fibular head and superior margin of the calcaneal tuberosity. @*Results@#The intramuscular neural distribution for the medial and lateral parts of the gastrocnemius had the greatest arborized patterns in the 7/10–8/10 section of the medial head and 7.5/10–8.5/10 section of the lateral part of the gastrocnemius. @*Conclusion@#We propose that BoNT injections should be directed to the 7/10–8/10 section of the medial head and the 7.5/10– 8.5/10 section of the lateral part of the gastrocnemius. Following our guidelines, clinicians can ensure satisfactory results with the use of minimal doses to limit adverse effects, such as gait disturbance, antibody production, and bruising, due to multiple injections. The results can also be altered and applied to electromyography.

ABSTRACT

Background@#Atopic dermatitis (AD) is a chronic pruritic inflammatory dermatosis. Whether gamma-linolenic acid (GLA) supplementation is beneficial in AD patients remains debatable. @*Objective@#This study investigated whether adjuvant GLA supplementation is associated with clinical improvement in AD patients receiving systemic treatment, as assessed by patient-reported outcome measures. @*Methods@#We enrolled 70 AD patients. Patients who received GLA at a dose of 80∼160 mg/d for over 1 month were included in the GLA group, while others were included in the non-GLA group. Each group was subgrouped into control, immunomodulator, and dupilumab groups based on treatment history. The patients evaluated their symptoms using the Atopic Dermatitis Control Tool (ADCT), Patient Global Assessment of Disease (PGA), and Dermatology Life Quality Index (DLQI). @*Results@#The Mann-Whitney U-test was used to compare differences in ADCT, PGA, and DLQI between both groups. The ADCT scores were significantly lower in the control and immunomodulatory group supplemented with GLA (control U=13.5, p=0.04; immunomodulatory U=28.0, p=0.01), but not in patients taking dupilumab (U=44.5, p=0.70). The PGA and DLQI scores also tended to be lower in the GLA group than those in the non-GLA group. @*Conclusion@#GLA supplementation is a potential adjuvant to systemic therapy may yield additional symptomatic relief in AD patients.

ABSTRACT

A few cases of rosacea-like eruptions associated with COVID-19 vaccination have been reported. Herein, we report a case of papulopustular rosacea-like eruption following COVID-19 vaccination in an Asian male. A 46-year-old male patient presented with pruritic and pricking erythematous papules, as well as pustules on the face for 6 months.The lesions developed 1 month after the second dose of the BNT162b2 COVID-19 vaccine and improved, but the lesion recurred 1 month after the third dose of vaccine. Histopathological examination revealed moderate perivascular lymphohistiocytic and a few eosinophilic infiltrates in the upper dermis. He was treated with oral triamcinolone and doxycycline, and the lesion improved gradually over 4 months. Although its exact etiology is unclear, the immune response after COVID-19 vaccination may play a role in the onset of rosacea-like eruption. Clinicians should be aware that rosacea-like eruption are a possible cutaneous reaction after COVID-19 vaccination.

ABSTRACT

Background@#Optimizing endotracheal tube (ETT) shape is important for successful videolaryngoscope-aided intubation. This prospective randomized controlled study aimed to compare the tube-handling time between a C-curved and hockey stick-shaped stylet in infants and neonates using the C-MAC® videolaryngoscope Miller blade. @*Methods@#A total of 110 infants (age < 1 year) were randomly assigned to either the hockey stick-curved stylet group (group H, n = 53) or the C-curved stylet group (group C, n = 57). The primary outcome was tube handling time after glottis visualization and the secondary outcomes were the total intubation time, incidence of successful intubation, initial tube tip location at the laryngeal inlet, and numerical rating scale for ease of intubation. @*Results@#Tube insertion time and total intubation duration (both in seconds) were significantly shorter in group C than in group H (13.3 ± 8.9 vs. 25.1 ± 27.0, P = 0.002; 19.9 ± 9.4 vs. 32.8 ± 27.1, P = 0.001, respectively). Group C displayed a higher rate of intubation success within 30 s than group H (87.7% vs. 69.8%, P = 0.029). The initial tube tip was located at the center in 34 children in group C (59.6%) and 12 children in group H (26.1%, P < 0.001). Laryngoscope operators rated intubation as easier when provided with a C-curved stylet. @*Conclusions@#In neonates and infants, modification of the ETT shape into a C-curve may reduce tube handling time compared to the conventional hockey stick-shaped tube during intubation using a C-MAC® video laryngoscope Miller blade.

ABSTRACT

Background@#Although fiberoptic-guided endotracheal intubation using a supraglottic airway device (SAD) is a good alternative for the management of difficult airways, its learning curve for residents has not been evaluated in pediatric patients. We aimed to train residents using a pediatric manikin and obtain learning curves to evaluate the efficiency of the training. @*Methods@#We conducted a single-armed prospective study with anesthesiology residents. Plain endotracheal tube (ETT) intubation guided by a fiberoptic bronchoscope through Ambu® AuraGainTM was demonstrated in a pediatric manikin to the participants before training. The procedure was divided into four steps: SAD insertion, vocal cord identification, carina identification, and ETT insertion into the trachea. The results and elapsed procedure times of each trial were recorded. The learning curves for the participants were constructed and analyzed using the cumulative sum method. @*Results@#All the 30 participants acquired proficiency at the end of practice between eight and 25 trials. The overall success rate for the procedure was 92.8%, and above 80% for all participants. Mean ± standard deviation procedure time was 71.3 ± 50.7 s. The 4th step accounted for 86.2% and 48.0% of the total failures and procedure time, respectively. The procedure time rapidly decreased in the 2nd trial; a modest decline was observed thereafter. @*Conclusions@#Trainees can obtain proficiency for fiberoptic-guided intubation through SAD within 25 times when using pediatric manikin. Effect of the training on performance in actual clinical situation should be studied.

ABSTRACT

Background@#Many studies have examined the risk factors for postoperative acute kidney injury (AKI), but few have focused on intraoperative peripheral perfusion index (PPI) that has recently been shown to be associated with postoperative morbidity and mortality. Therefore, this study aimed to evaluate the relationship between intraoperative PPI and postoperative AKI under the hypothesis that lower intraoperative PPI is associated with AKI occurrence. @*Methods@#We retrospectively searched electronic medical records to identify patients who underwent surgery at the general surgery department from May 2021 to November 2021. Patient baseline characteristics, pre- and post-operative laboratory test results, comorbidities, intraoperative vital signs, and discharge profiles were obtained from the Institutional Clinical Data Warehouse and VitalDB. Intraoperative PPI was the primary exposure variable, and the primary outcome was postoperative AKI. @*Results@#Overall, 2,554 patients were identified and 1,586 patients were included in our analysis. According to Kidney Disease Improving Global Outcomes (KDIGO) criteria, postoperative AKI occurred in 123 (7.8%) patients. We found that risks of postoperative AKI increased (odds ratio: 2.00, 95% CI [1.16, 3.44], P = 0.012) when PPI was less than 0.5 for more than 10% of surgery time. Other risk factors for AKI occurrence were male sex, older age, higher American Society of Anesthesiologists physical status, obesity, underlying renal disease, prolonged operation time, transfusion, and emergent operation. @*Conclusions@#Low intraoperative PPI was independently associated with postoperative AKI.

ABSTRACT

Background and Objectives@#Paroxysmal atrial fibrillation (AF) is a major potential cause of embolic stroke of undetermined source (ESUS). However, identifying AF remains challenging because it occurs sporadically. Deep learning could be used to identify hidden AF based on the sinus rhythm (SR) electrocardiogram (ECG). We combined known AF risk factors and developed a deep learning algorithm (DLA) for predicting AF to optimize diagnostic performance in ESUS patients. @*Methods@#A DLA was developed to identify AF using SR 12-lead ECG with the database consisting of AF patients and non-AF patients. The accuracy of the DLA was validated in 221 ESUS patients who underwent insertable cardiac monitor (ICM) insertion to identify AF. @*Results@#A total of 44,085 ECGs from 12,666 patient were used for developing the DLA. The internal validation of the DLA revealed 0.862 (95% confidence interval, 0.850–0.873) area under the curve (AUC) in the receiver operating curve analysis. In external validation data from 221 ESUS patients, the diagnostic accuracy of DLA and AUC were 0.811 and 0.827, respectively, and DLA outperformed conventional predictive models, including CHARGE-AF,C2HEST, and HATCH. The combined model, comprising atrial ectopic burden, left atrial diameter and the DLA, showed excellent performance in AF prediction with AUC of 0.906. @*Conclusions@#The DLA accurately identified paroxysmal AF using 12-lead SR ECG in patients with ESUS and outperformed the conventional models. The DLA model along with the traditional AF risk factors could be a useful tool to identify paroxysmal AF in ESUS patients.

ABSTRACT

Rhythm control therapy is used in atrial fibrillation (AF) management to improve AF-related symptoms along with rate control. AF catheter ablation is effective in maintaining sinus rhythm and has an acceptable complication rate. Compared with antiarrhythmic drugs, AF catheter ablation is superior with respect to arrhythmia-free survival and improvement in the quality of life. Therefore, AF ablation is recommended for rhythm control after the failure of antiarrhythmic drugs and is sometimes considered a first-line therapy for AF patients. Radiofrequency and cryoballoon ablation show similar efficacy, with slightly different complication profiles. Surgery for AF is also an effective rhythm control therapy and should be considered in patients undergoing cardiac surgery or in those with failed catheter ablation. For patients undergoing AF catheter ablation, performing ablation under uninterrupted warfarin or non-vitamin K oral anticoagulant treatment is recommended for periprocedural stroke risk management. Here, we review existing data and discuss the general principles of AF catheter and surgical ablation in patients with AF.

ABSTRACT

Background/Aims@#Veno-occlusive disease/sinusoidal obstruction syndrome (VOD/SOS) is one of the most fatal complications of hematopoietic cell transplantation (HCT), and defibrotide is the only curative drug. We conducted this study to confirm the survival rate of VOD/SOS patients diagnosed in Korea and assess the efficacy of defibrotide. @*Methods@#Patients diagnosed with VOD/SOS after allogenic HCT between 2003 and 2020 were enrolled. We investigated day +100 survival rates and associated risk factors in patients who satisfied the modified Seattle criteria within 50 days of HCT. @*Results@#A total of 110 patients satisfied the modified Seattle criteria, of which 65.5% satisfied the Baltimore criteria. Thirty-seven patients were treated with defibrotide. The day +100 survival rate of the 110 patients was 65.3%. The survival rates in patients who did not meet the Baltimore criteria and in those who did were 86.8% and 53.7%, respectively (p = 0.001). The day +100 survival rate of patients treated with defibrotide was 50.5%. Among the patients receiving defibrotide, those whose creatinine levels were more than 1.2 times the baseline had a significantly lower survival rate at 26.7% (p = 0.014). On multivariate regression analysis, the hazard ratio of satisfaction of the Baltimore criteria was 4.54 (95% confidence interval [CI], 1.69 to 12.21; p = 0.003). In patients treated with defibrotide, the hazard ratio was 8.70 (95% CI, 2.26 to 33.45; p = 0.002), when creatinine was more than 1.2 times the baseline on administration. @*Conclusions@#The day +100 survival rate was significantly lower when the Baltimore criteria were satisfied, and when there was an increase in creatinine at the time of defibrotide administration.

ABSTRACT

Complications in autologous hair transplantation are rare, with minor complications that can follow any surgical intervention. A 37-year-old female presented with pruritic, solitary, 0.6-cm-sized, skin-colored nodule on the forehead at one month after autologous hair transplantation. Histopathological findings revealed diffuse dermal granulomatous reactions with multinucleated giant cells, histiocytes, and lymphocytes around the implanted hair follicles, suggestive of foreign body reaction. The patient was treated with 3 courses of 2.5 mg/mL triamcinolone intralesional injections at 4-week intervals. Despite treatment, the lesion remained, and a novel lesion appeared near the existing lesion.Total punch removal of the lesions was performed, and the lesions resolved without recurrence for 6 weeks. A foreign body reaction in hair transplantation surgery is thought to be a rare complication after implantation of the patient’s hair has replaced synthetic fibers. Herein, we report a case of foreign body reaction caused by hair transplantation treated with total removal of the lesion.

ABSTRACT

Background@#Dermatofibromas (DF) are fibrohistiocytic tumors of unknown etiology, and multiple DF (MDF) are relatively rare. MDF have been reported in the setting of autoimmune diseases, human immunodeficiency virus infection, or comorbidities treated with immunosuppressive drugs. @*Objective@#The present study investigated whether underlying conditions with impaired immune function are associated with MDF. @*Methods@#A total of 338 patients with DF was enrolled. We divided patients into two groups as MDF and solitary DF (SDF) groups. We retrospectively reviewed patient medical records and classified all patients by underlying diseases. Statistical significance of SDF and MDF for each conditions was analyzed. @*Results@#The demographics and comorbidities were compared between MDF group (n=82) and SDF group (n=256). Among underlying conditions, systemic lupus erythematosus (SLE) (odds ratio, 10.397; 95% confidence interval, 2.743∼39.404; p<0.001) was significantly associated with MDF over SDF. Vitiligo and post status of kidney transplant were related more highly to MDF (p=0.014; p=0.014, respectively) than to SDF. Presence of overall comorbidities, autoimmune diseases, and immunosuppressive drug use were associated with DF number (p<0.001;p<0.001; p<0.001, respectively). @*Conclusion@#We propose an association between MDF and comorbidities, especially SLE and immunosuppressant use. MDF lesions seem to be impacted by compromised immune function. This is of significance since it is essential to search for associated conditions in patients presenting with MDF in dermatologic clinical settings.

ABSTRACT

Purpose@#Angiotensin-converting enzyme inhibitors (ACEIs) are medications generally prescribed for patients with high cardiovascular risk; however, they are suboptimally used due to frequent adverse events (AEs). The present study aimed to identify and replicate the genetic variants associated with ACEI-related AEs in the Korean population. @*Materials and Methods@#A two-stage approach employing genome-wide association study (GWAS)-based discovery and replication through target sequencing was used. In total, 1300 individuals received ACEIs from 2001 to 2007; among these, 228 were selected for GWAS. An additional 336 patients were selected for replication after screening 1186 subjects treated from 2008 to 2018.Candidate genes for target sequencing were selected based on the present GWAS, previous GWASs, and data from the PharmGKB database. Furthermore, association analyses were performed between no AE and AE or cough groups after target sequencing. @*Results@#Five genes, namely CRIM1, NELL1, CACNA1D, VOPP1, and MYBPC1, were identified near variants associated with ACEIrelated AEs. During target sequencing of 34 candidate genes, six single-nucleotide polymorphisms (SNPs; rs5224, rs8176786, rs10766756, rs561868018, rs4974539, and rs10946364) were replicated for association with all ACEI-related AEs. Four of these SNPs and rs147912715 exhibited associations with ACEI-related cough, whereas four SNPs (rs5224, rs81767786, rs10766756, and rs4974539 near BDKRB2, NELL1, NELL1 intron, and CPN2, respectively) were significantly associated with both categories of AEs. @*Conclusion@#Several variants, including novel and known variants, were successfully replicated and found to have associations with ACEI-related AEs. These results provide rare and clinically relevant information for safer use of ACEIs.

ABSTRACT

Warty dyskeratoma (WD) is an uncommon skin tumor that histologically presents as focal acantholysis and dyskeratosis and is a common finding among acantholytic diseases such as Darier’s disease. WD most commonly occurs on the head or neck of adults as an isolated papule or nodule. To our knowledge, only 6 cases of WD in the genital area have been previously reported in the literature, and no case have occurred on the scrotum to date.We report the first case of multiple WD that occurred on the scrotum successfully treated with 0.025% tretinoin cream. A 55-year-old male presented with asymptomatic, multiple, 0.1∼0.2-cm-sized, skin-colored papules on the scrotum for the previous 6 months. A skin punch biopsy and human papillomavirus (HPV) polymerase chain reaction test were performed for a clinical suspicion of genital warts or bowenoid papulosis. The histopathologic examination showed cup-shaped epidermal invaginations with central keratotic plug. Prominent villi, acantholytic clefting and corps ronds were also shown. The patient tested negative for HPV and was diagnosed with WD with typical pathologic findings. The patient was treated with 0.025% tretinoin cream for 2 weeks, and the lesions decreased in both size and number.
