Background:
Atopic dermatitis (AD) is a chronic inflammatory cutaneous disorder, that emerges from intricate interplays among genetic predisposition, immune dysregulation, environmental factors, and compromised skin barrier. Understanding the inflammatory pathway in AD is important due to its fundamental role in the pathogenesis of AD. This study aimed to explore the diverse spectrum of proteins linked to the inflammation of AD and the relationship between systemic biomarkers and clinical severity in AD.
Methods:
We examined the blood samples from 48 patients with AD and 48 healthy controls (HCs) using the Proximity Extension Assay (Olink). Differentially expressed proteins (DEPs) were identified and Pearson correlation analysis was conducted to determine systemic proteomic biomarkers associated with severity of AD.
Results:
A total of 29 DEPs were significantly up-regulated and 2 DEPs were significantly down-regulated in AD compared with the HC. The MCP-4, IL-18, MCP-3, TNFRSF9, and IL-17C were the top 5 highest DEPs associated with the severity of AD.
Conclusion
Our study sheds light on the intricate network of inflammatory proteins in AD and their potential implications for disease severity. Our results indicate that these systemic inflammatory proteins could be valuable for assessing AD severity and enhancing our understanding of the disease's complexity and its potential management strategies.

Background:
Primary cicatricial alopecia (PCA) is a rare disease that causes irreversible destruction of hair follicles and affects the quality of life (QOL).
Objective:
We aimed to investigate the disease awareness, medical use behavior, QOL, and real-world diagnosis and treatment status of patients with PCA.
Methods:
A self-administered questionnaire was administered to patients with PCA and their dermatologists. Patients aged between 19 and 75 years who visited one of 27 dermatology departments between September 2021 and September 2022 were included.
Results:
In total, 274 patients were included. The male-to-female ratio was 1:1.47, with a mean age of 45.7 years. Patients with neutrophilic and mixed PCA were predominantly male and younger than those with lymphocytic PCA. Among patients with lymphocytic PCA, lichen planopilaris was the most common type, and among those with neutrophilic PCA, folliculitis decalvans was the most common type. Among the total patients, 28.8% were previously diagnosed with PCA, 47.0% were diagnosed with PCA at least 6 months after their first hospital visit, 20.0% received early treatment within 3 months of disease onset, and 54.4% received steady treatment. More than half of the patients had a moderate to severe impairment in QOL. Topical/intralesional steroid injections were the most common treatment. Systemic immunosuppressants were frequently prescribed to patients with lymphocytic PCA, and antibiotics were mostly prescribed to patients with neutrophilic PCA.
Conclusion
This study provides information on the disease awareness, medical use behavior, QOL, diagnosis, and treatment status of Korean patients with PCA. This can help dermatologists educate patients with PCA to understand the necessity for early diagnosis and steady treatment.

Objective:
We aimed to evaluate the usefulness of arterial subtraction images for predicting the viability of hepatocellular carcinoma (HCC) after locoregional therapy (LRT) using gadoxetic acid-enhanced MRI and the Liver Imaging Reporting and Data System treatment response (LR-TR) algorithm.
Materials and Methods:
This study included 90 patients (mean age ± standard deviation, 57 ± 9 years) who underwent liver transplantation or resection after LRT and had 73 viable and 32 nonviable HCCs. All patients underwent gadoxetic acid-enhanced MRI before surgery. Two radiologists assessed the presence of LR-TR features, including arterial phase hyperenhancement (APHE) and LR-TR categories (viable, nonviable, or equivocal), using ordinary arterial-phase and arterial subtraction images. The reference standard for tumor viability was surgical pathology. The sensitivity of APHE for diagnosing viable HCC was compared between ordinary arterial-phase and arterial subtraction images. The sensitivity and specificity of the LR-TR algorithm for diagnosing viable HCC was compared between the use of ordinary arterial-phase and the use of arterial subtraction images.Subgroup analysis was performed on lesions treated with transarterial chemoembolization (TACE) only.
Results:
The sensitivity of APHE for viable HCCs was higher for arterial subtraction images than ordinary arterial-phase images (71.2% vs. 47.9%; p < 0.001). LR-TR viable category with the use of arterial subtraction images compared with ordinary arterial-phase images showed a significant increase in sensitivity (76.7% [56/73] vs. 63.0% [46/73]; p = 0.002) without significant decrease in specificity (90.6% [29/32] vs. 93.8% [30/32]; p > 0.999). In a subgroup of 63 lesions treated with TACE only, the use of arterial subtraction images showed a significant increase in sensitivity (81.4% [35/43] vs. 67.4% [29/43]; p = 0.031) without significant decrease in specificity (85.0% [17/20] vs. 90.0% [18/20]; p > 0.999).
Conclusion
Use of arterial subtraction images compared with ordinary arterial-phase images improved the sensitivity while maintaining specificity for diagnosing viable HCC after LRT using gadoxetic acid-enhanced MRI and the LR-TR algorithm.

BACKGROUND: Process dissociation procedure has been used to evaluate explicit and implicit memories. Two process-dissociation measurement models are described. METHODS: This prospective study evaluated intraoperative memory formation in Korean patients undergoing elective surgery under general anesthesia and its relation to the depth of hypnotic state. A total of 270 patients enrolled were randomly assigned to three groups based on Bispectral Index (BIS) values in the following ranges: 30 to 40, BIS 40 to 50, and BIS 50 to 60 according to the level of hypnotic depth induced by propofol or sevoflurane during the presentation of wordlists. When the level of hypnotic depth was maintained at the target BIS range, words were played for 15 minutes via headphones to patients. Within 24 hours after the word presentation, memory was assessed using an auditory word stem completion test. The probability of explicit and implicit memory was calculated using original and extended measurement models. Brice interviews were performed within 1 and 24 hours after surgery. RESULTS: A total of 119 patients who did not deviate from the target BIS range were included in the analysis. The 95% confidence interval (CI) of the probability of occurrence of implicit memory evaluated by the original model did not include zero. However, when the extension model was used, 0 was included in the 95% CI. Explicit memory evaluated via Brice interviews did not occur in any group. CONCLUSIONS: When BIS was maintained in the range of 30 to 60 during surgery, no explicit or implicit memory was observed.

PURPOSE: The purpose of this study was to evaluate the proper axial thickness of zirconia abutment applied to implant in the anterior region. MATERIALS AND METHODS: Zirconia abutments were prepared at different axial wall thickness by processing pre-sintered zirconia blocks via CAD/CAM to obtain equal specimens. The abutments were each produced with a thickness of 0.5 mm (Group 1), 0.8 mm (Group 2), 1.2 mm (Group 3), or 1.5 mm (Group 4). The implant used in this study was a external connection type one (US, Osstem, Pussan, Korea) product and the zirconia abutment was prepared via replication of a cemented abutment. The crowns were prepared via CAM/CAM with a thickness of 1.5 mm and were cemented to the abutments using RelyX(TM) UniCem cement. A universal testing machine was used to apply load at 30 degrees and measure fracture strength of the zirconia abutment. RESULTS: Fracture strength of the abutments for Group 1, Group 2, Group 3, and Group 4 were 236.00 +/- 67.55 N, 599.00 +/- 15.80 N, 588.20 +/- 33.18 N, and 97.83 +/- 98.13 N, respectively. Group 1 showed a significantly lower value, as compared to the other groups (independent Mann-Whitney U-test. P<.05). No significant differences were detected among Group 2, Group 3, and Group 4 (independent Mann-Whitney U-test. P>.05). CONCLUSION: Zirconia abutment requires optimal thickness for fracture resistance. Within the limitation of this study, > 0.8 mm thickness is recommended for zirconia abutment in anterior implants.

OBJECTIVES: This study was performed to consider the clinical experience of surgical outcome of single port access (SPA) laparoscopic myomectomy according to suturing methods. METHODS: The authors operated with 2 suturing method in SPA laparoscopic myomectomy for 246 patients and compared the surgical outcomes. RESULTS: The some significant difference of surgical outcome according to two suturing methods was demonstrated. Operating time was 100.50 minutes (+/- 42.09 minutes) in interrupted suture method group than 121.04 minutes (+/- 61.56 minutes) in continuous interlocking suture method group (P = 0.021). Estimated blood loss was less 222.59 mL (+/- 144.94 mL) in interrupted suture group than 340.11 mL (+/- 380.62 mL) in continuous interlocking suture method group (P = 0.042). CONCLUSION: This experience suggests that interrupted suture method was effective for operating time and estimated blood loss than continuous interlocking method in SPA laparoscopic myomectomy.

OBJECTIVES: Type 2 diabetes, a leading cause of cardiovascular disease, is well known for its association with accelerated atherosclerosis. Adiponectin and tumor necrosis factor - alpha (TNF-alpha), which are produced and secreted in adipose tissue, have been suggested as predictors for cardiovascular disease. However, little is known about the influence of adiponectin and TNF-alpha ratio on the progression of carotid atherosclerosis in newly diagnosed type 2 diabetic patients. This study was conducted to evaluate the influence of serum adiponectin/TNF-alpha levels on the progression of carotid atherosclerosis. METHODS: One hundred eleven newly diagnosed type 2 diabetes patients were enrolled. Anthropometric and biochemical data including serum adiponectin, TNF-alpha were measured for each participant. Also we measured carotid intima-media thickness (CIMT) at baseline and at 1 year follow-up (n=81). We finally examined the relationship among serum adiponectin over TNF-alpha levels (ADPN/TNF-alpha), baseline CIMT, and progression of CIMT at 1 year. RESULTS: ADPN/TNF-alpha negatively correlated with baseline CIMT (r=-0.231, p=0.025). Moreover, progression of CIMT was significant at 1 year (0.011+/-0.138 mm). There was a negative correlation between ADPN/TNF-alpha and progression of CIMT at 1 year (r=-0.172, p=0.038). In multiple regression analysis, age and HbA1c were found to be independent risk factors for baseline CIMT. However, only HbA1c was an independent risk factor for the progression of CIMT. CONCLUSION: ADPN/TNF-alpha was negatively associated with baseline CIMT and the progression of CIMT at 1 year. Overall glycemic control is the most important factor in the progression of CIMT in patients with type 2 diabetes.

Metastases from hepatocellular carcinoma to the bones of the hands or feet are rare. They are usually a late manifestation of a disseminated tumor but may also be the primary manifestation of an occult cancer. Clinically, the metastasis may mimic benign tumors or non-neoplastic osteoarthritic conditions; thus, resulting in misdiagnosis and improper treatment. We report a case of acrometastasis to the right first metatarsal bone in a 70-year-old man with hepatocellular carcinoma.

BACKGROUND/AIMS: The most appropriate treatment for acute gastric variceal bleeding (GVB) is currently endoscopic gastric variceal obturation (GVO) using Histoacryl(R). However, the secondary prophylactic efficacy of beta-blocker (BB) after GVO for the first acute episode of GVB has not yet been established. The secondary prophylactic efficacy of BB after GVO for the first acute episode of GVB was evaluated in this study. METHODS: Ninety-three patients at Soonchunhyang University Hospital with acute GVB who received GVO using Histoacryl(R) were enrolled between June 2001 and March 2010. Among these, 42 patients underwent GVO alone (GVO group) and 51 patients underwent GVO with adjuvant BB therapy (GVO+BB group). This study was intended for patients in whom a desired heart rate was reached. The rates of rebleeding-free survival and overall survival were calculated for the two study groups using Kaplan-Meyer analysis and Cox's proportional-hazards model. RESULTS: The follow-up period after the initial eradication of gastric varices was 18.14+/-25.22 months (mean+/-SD). During the follow-up period, rebleeding occurred in 10 (23.8%) and 21 (41.2%) GVO and GVO+BB patients, respectively, and 39 patients died [23 (54.8%) in the GVO group and 16 (31.4%) in the GVO+BB group]. The mean rebleeding-free survival time did not differ significantly between the GVO and GVO+BB groups (65.40 and 37.40 months, respectively; P=0.774), whereas the mean overall survival time did differ (52.54 and 72.65 months, respectively; P=0.036). CONCLUSIONS: Adjuvant BB therapy after GVO using Histoacryl(R) for the first acute episode of GVB could decrease the mortality rate relative to GVO alone. However, adjuvant BB therapy afforded no benefit for the secondary prevention of rebleeding in GV.
