Résumé
Purpose@#The aim of this study was to assess the feasibility and efficacy of an ultrasound needle guidance system (NGS) based on standard needle magnetization in a phantom study of thyroid nodule (TN)-targeting punctures. @*Methods@#Six trainees and a staff radiologist performed TN-targeting punctures with or without the NGS in phantom models (group 1, experience <50 cases; group 2, experience ≥50 cases and <100 cases; group 3, experience ≥100 cases of TN-targeting punctures). The feasibility, technical success rate, number of punctures, and procedure time were recorded. @*Results@#The feasibility of NGS was 98.6% (138/140). In group 1, the technical success rate increased from 60.0%±8.2% to 80.0%±8.2% when the NGS was used (P=0.046), with a reduction in the number of punctures from 2.2 to 1.2 (P=0.005). In group 2, the rate changed from 95.0%±5.8% to 100.0%±0.0% with the NGS (P=0.157), with a minimal decrease in the number of punctures from 1.1 to 1.0 (P=0.157). The procedure time significantly decreased in both groups (P=0.041 and P=0.010, respectively) when the NGS was used. In group 3, there were no significant differences in the technical success rate and the number of punctures according to whether the NGS was used (P=0.317 and P=0.317, respectively). @*Conclusion@#NGS using standard needle magnetization is technically feasible and has potential to improve the efficacy of TN-targeting punctures for less-experienced operators, especially beginners, according to the findings of this phantom study.

Objective@#To determine the usefulness of Silent MR angiography (MRA) for evaluating intracranial aneurysms treated with stent-assisted coil embolization. @*Materials and Methods@#Ninety-nine patients (101 aneurysms) treated with stent-assisted coil embolization (Neuroform atlas, 71 cases; Enterprise, 17; LVIS Jr, 9; and Solitaire AB, 4 cases) underwent time-of-flight (TOF) MRA and Silent MRA in the same session using a 3T MRI system within 24 hours of embolization. Two radiologists independently interpreted both MRA images retrospectively and rated the image quality using a 5-point Likert scale. The image quality and diagnostic accuracy of the two modalities in the detection of aneurysm occlusion were further compared based on the stent design and the site of aneurysm. @*Results@#The average image quality scores of the Silent MRA and TOF MRA were 4.38 ± 0.83 and 2.78 ± 1.04, respectively (p < 0.001), with an almost perfect interobserver agreement. Silent MRA had a significantly higher image quality score than TOF MRA at the distal internal carotid artery (n = 57, 4.25 ± 0.91 vs. 3.05 ± 1.16, p < 0.001), middle cerebral artery (n = 21, 4.57 ± 0.75 vs. 2.19 ± 0.68, p < 0.001), anterior cerebral artery (n = 13, 4.54 ± 0.66 vs. 2.46 ± 0.66, p < 0.001), and posterior circulation artery (n = 10, 4.50 ± 0.71 vs. 2.90 ± 0.74, p = 0.013). Silent MRA had superior image quality score to TOF MRA in the stented arteries when using Neuroform atlas (4.66 ± 0.53 vs. 3.21 ± 0.84, p < 0.001), Enterprise (3.29 ± 1.59 vs. 1.59 ± 0.51, p = 0.003), LVIS Jr (4.33 ± 1.89 vs. 1.89 ± 0.78, p = 0.033), and Solitaire AB stents (4.00 ± 2.25 vs. 2.25 ± 0.96, p = 0.356). The interpretation of the status of aneurysm occlusion exhibited significantly higher sensitivity with Silent MRA than with TOF MRA when using the Neuroform Atlas stent (96.4% vs. 14.3%, respectively, p < 0.001) and LVIS Jr stent (100% vs. 20%, respectively, p = 0.046). @*Conclusion@#Silent MRA can be useful to evaluate aneurysms treated with stent-assisted coil embolization, regardless of the aneurysm location and type of stent used.
Résumé
Purpose@#To compare differences between the original criteria for diagnosis of ocular sarcoidosis (OS) (first International Workshop for OS [IWOS] 2009) and the revised criteria (sixth IWOS 2017), and their clinical usefulness when assessing OS in Korean patients. @*Methods@#We analyzed patients with suspected OS who visited our tertiary referral ophthalmological and pulmonary clinic from 2007 to 2018. We diagnosed patients using both sets of criteria. Blood test and biopsy data (collected by physicians) and slit-lamp, fundus, and fluorescein angiography data (collected by ophthalmologists) were reviewed. @*Results@#Thirty-four patients were diagnosed using both criteria. Of 32 patients who underwent biopsies, 31 had OS (96.87%). Using either set of criteria, 31 patients were diagnosed with definite OS and two with presumed OS. One patient diagnosed with possible OS using the previous criteria was diagnosed with presumed OS using the revised criteria. The new criteria add the lysozyme level, the CD4/CD8 ratio, and positron emission tomography imaging data to the old criteria and add the descriptors “presumed OS” and “probable OS”. There is no need to use the revised criteria in Korea; the biopsy and imaging data are adequately diagnostic. @*Conclusions@#IWOS revised the OS diagnostic criteria by adding new parameters. However, this was unnecessary for Korea, where the biopsy and imaging data are adequately diagnostic.

OBJECTIVES@#This study aimed to investigate the association between depression with atypical features and metabolic syndromes in Korean adults using the 2016 Korean National Health and Nutrition Examination Survey (KNHANES) data.@*METHODS@#We used the 2016 KNHANES data to enroll 277 participants with a score of 10 or higher on Patient Health Questionnaire-9. Depression with atypical features was diagnosed when at least two of the following criteria were met : 1) sleeping more than 10 hours a day ; 2) weight gain of more than 3 kg in a year ; and 3) fatigue/anergia. Depression was divided into two groups based on the presence/absence of atypical features. Physical and mental health, and risk of metabolic syndrome were compared between the groups.@*RESULTS@#Among the 277 participants, 91 had depression with atypical features. We identified significant differences in age, sex, income, and education between the two groups. After adjusting for these variables, depression with atypical features had lower EuroQol-5D index scores (p<0.001) and higher prevalence of metabolic syndromes (p=0.035) compared to the depression without atypical features. Depression with atypical features had higher odds ratio (OR) in association with metabolic syndromes after adjusting for confounding variables (OR=1.923 ; 95% confidence interval : 1.069–3.460).@*CONCLUSIONS@#Depression with atypical features increases the risk of metabolic syndromes and lowers the quality of life.
Résumé
BACKGROUND: Billroth I anastomosis is one of the most common reconstruction methods after distal gastrectomy for gastric cancer. Intracorporeal Billroth I (ICBI) anastomosis and extracorporeal Billroth I (ECBI) anastomosis are widely used in laparoscopic surgery. Here we compared ICBI and ECBI outcomes at a major gastric cancer center. METHODS: We retrospectively analyzed data from 2,284 gastric cancer patients who underwent laparoscopic distal gastrectomy between 2009 and 2017. We divided the subjects into ECBI (n=1,681) and ICBI (n=603) groups, compared the patients’ clinical characteristics and surgical and short-term outcomes, and performed risk factor analyses of postoperative complication development. RESULTS: The ICBI group experienced shorter operation times, less blood loss, and shorter hospital stays than the ECBI group. There were no clinically significant intergroup differences in diet initiation. Changes in white blood cell counts and C-reactive protein levels were similar between groups. Grade II–IV surgical complication rates were 2.7% and 4.0% in the ECBI and ICBI groups, respectively, with no significant intergroup differences. Male sex and a body mass index (BMI) ≥30 were independent risk factors for surgical complication development. In the ECBI group, patients with a BMI ≥30 experienced a significantly higher surgical complication rate than those with a lower BMI, while no such difference was observed in the ICBI group. CONCLUSION: The surgical safety of ICBI was similar to that of ECBI. Although the chosen anastomotic technique was not a risk factor for surgical complications, ECBI was more vulnerable to surgical complications than ICBI in patients with a high BMI (≥30).

Schizophrenia is a major chronic mental illness with various symptoms that is often accompanied by substance use disorders. Patients with schizophrenia have a higher smoking rate than the general population and a lower smoking cessation success rate. Further, their motivation for smoking cessation is often low. Individuals with schizophrenia that are past or present cigarette smokers are more difficult to treat in terms of psychotic symptoms, are more likely to have physical illnesses, and have higher mortality rates. A variety of treatments, both pharmacological and non-pharmacological, are used to aid smoking cessation in patients with schizophrenia. Among these, bupropion, varenicline, and nicotine replacement therapy can be safely used in patients with schizophrenia, and several studies have demonstrated their effects. Cigarette smoking is an important health problem. The study of smoking cessation in individuals with schizophrenia may help improve their ability to function and their quality of life through active evaluation and treatment.

PURPOSE: To investigate the relationship between the progression of visual field (VF) loss and changes in lamina cribrosa depth (LCD) as determined by spectral-domain optical coherence tomography (SD-OCT) enhanced depth imaging in patients with primary open angle glaucoma (POAG). METHODS: Data from 60 POAG patients (mean follow-up, 3.5 ± 0.7 years) were included in this retrospective study. The LCD was measured in the optic disc image using SD-OCT enhanced depth imaging scanning at each visit. Change in the LCD was considered to either ‘increase’ or ‘decrease’ when the differences between baseline and the latest two consecutive follow-up visits were greater than the corresponding reproducibility coefficient value (23.08 µm, as determined in a preliminary reproducibility study). All participants were divided into three groups: increased LCD (ILCD), decreased LCD (DLCD), and no LCD change (NLCD). The Early Manifest Glaucoma Trial criteria were used to define VF deterioration. Kaplan-Meier survival analysis and Cox's proportional hazard models were performed to explore the relationship between VF progression and LCD change. RESULTS: Of the 60 eyes examined, 35.0% (21 eyes), 28.3% (17 eyes), and 36.7% (22 eyes) were classified as the ILCD, DLCD, and NLCD groups, respectively. Kaplan-Meier survival analysis showed a greater cumulative probability of VF progression in the ILCD group than in the NLCD (p < 0.001) or DLCD groups (p = 0.018). Increased LCD was identified as the only risk factor for VF progression in the Cox proportional hazard models (hazard ratio, 1.008; 95% confidence interval, 1.000 to 1.015; p = 0.047). CONCLUSIONS: Increased LCD was associated with a greater possibility of VF progression. The quantitative measurement of LCD changes, determined by SD-OCT, is a potential biomarker for the prediction of VF deterioration in patients with POAG.

OBJECTIVE: With the burgeoning elderly population, mental health among the elderly has surfaced as an important medical, social, and economic issue. This study was a pilot study testing the assessment module that was developed to survey mental health among the elderly living in the city of Busan. METHODS: Basic demographic data and mental health problems were investigated using the General Health Questionnaire-12 (GHQ-12), suicide risk screening tool, subjective memory deterioration scale, sleep disorder and sleep pattern scale, health-related quality of life scale (EuroQoL-5 dimension), and alcohol abuse screening tool (Cut down, Annoyed, Guilty, Eye-opener Questionnaire). RESULTS: Four-hundred adults aged 65 years or older living in either of two districts in the Busan metropolitan city participated in the study, of whom 219 (54.8%) were female. About 26.8% of the participants were obese, while 2.3% were underweight. One hundred and twenty-five (31.3%) participants were in need of attention to or improvement of nutrition management, and 19.1% perceived themselves to be in poor health. In the GHQ-12, 68.8% were in psychological distress (≥2). About 49.8% of the participants had insomnia, 61.8% had subjective memory disturbance, and 6% were at risk of suicide. The GHQ-12 score, proportion of participants with sleep disturbance, and subjective memory deterioration was significantly higher among women than in men, while health-related quality of life was higher in men. CONCLUSION: A considerable number of older adults living in the Busan region were suffering from psychological stress, were in need of nutrition management, had low quality of life, and had poor mental health, and women were particularly more vulnerable.

PURPOSE: Various laparoscopic wedge resection (LWR) techniques requiring gastrotomy for gastrointestinal stromal tumors (GISTs) of the stomach have been applied to facilitate tumor resection and preserve the remnant gastric volume. However, there is the possibility of cancer cell dissemination during these procedures. The aim of this study was to assess the oncologic safety of LWR with gastrotomy (LWR-G) compared to LWR without luminal exposure. MATERIALS AND METHODS: Clinicopathologic and operative results of 193 patients who underwent LWR for gastric GIST were retrospectively analyzed from 2003 to 2013. We stratified the patients into two groups: LWR-G and LWR without gastrotomy (LWR-C). Clinicopathologic features, short-term outcomes, and long-term outcomes were compared. RESULTS: A total of 26 patients underwent LWR-G, and 167 patients underwent LWR-C. The LWR-G group showed significantly more anterior wall-located (n=10, 38.5%), intraluminal (n=20, 76.9%), and ulcerative (n=13, 50.0%) tumors than the LWR-C group (n=33, 19.8%; n=96, 57.5%; n=46, 27.5%, respectively). Postoperative short-term outcomes did not differ between the two groups. When tumor staging was compared, no statistical difference was noted. There was no recurrence in the LWR-G group, while 2 patients in the LWR-C group experienced recurrence. The two recurrences in the LWR-C group were found in the liver and in the remnant stomach at 63 and 12 months after the operation, respectively. No gastric GIST-related death was recorded in any group during the study period. CONCLUSIONS: LWR-G for gastric GIST is an oncologically safe procedure even for masses with ulcerations.
