A Case of Transient Posterior Capsular Opacity After Intravitreal Bevacizumab Injection

Purpose@#We are reporting a case of transient posterior capsular opacity after intravitreal Bevacizumab (Avastin®, Roche Pharma Schweis AG, Zurich, Switzerland) injection in a phakic patient.Case summary: A 34-year-old man visited our clinic with sudden blurred vision in his left eye one day after the intravitreal injection for central serous chorioretinopathy. His visual acuity was 1.0 before the injection and decreased to 0.1 at the presentation. On slit-lamp examination, a snow-flake appearance opacity was noted behind the posterior capsule. No newly appearing lesion was presented on fundus exam, so topical antibiotics and steroid eyedrops were continued. One week after the injection, the visual acuity improved to 1.0 and posterior capsular opacity remained but decreased. Five weeks after the injection, the posterior capsular opacity resolved. Fundus exam revealed improved but persistent subretinal fluid, so he overwent another intravitreal injection. The posterior capsular opacity did not recur for seven months. @*Conclusions@#Iatrogenic lens damage or the turbidity formed by medication can cause a posterior capsular opacity after intravitreal injection. If structural damage is uncertain, close monitoring is needed and ultimately, cataract surgery may be required for chronic crystalline lens opacity.

The Mediating Effect of Acceptance Action in the Relationship between Diabetes Distress and Self-stigma among Old Adults with Diabetes in South Korea

Purpose@#This study investigated the mediating effects of acceptance action on the relationship between diabetes distress and self-stigma in older adults with diabetes. @*Methods@#A descriptive research approach was adopted using 187 patients diagnosed with diabetes mellitus by an endocrinology doctor. The data were collected from 26 to 31 March, 2020 and were analyzed using descriptive statistics, t-test, one-way ANOVA, Pearson's correlation coefficient analysis, and hierarchical multiple regression. @*Results@#The mean scores for diabetes distress, self-stigma, and acceptance action were 2.98±0.64, 2.54±0.74, and 4.16±0.35, respectively. Acceptance action partially mediated the relationship between diabetes distress and self-stigma (z=1.98, p=.024), with an explanatory power of 51.0%. @*Conclusion@#To reduce diabetes self-stigma among old adults in diabetes distress situations, it is necessary to improve their acceptance action and develop step-by-step differentiated acceptance action enhancement programs through multidisciplinary collaborations.

Effects of Job Crafting on the Quality of Nursing Services among Clinical Nurses: The Mediating Effect of Work Engagement / 간호행정학회지

Purpose@#This study aimed to confirm the association between job crafting and quality of nursing services among Korean clinical nurses, as well as the mediating effect of work engagement. @*Methods@#Data from 194 hospital nurses were surveyed in this descriptive cross-sectional study. They were collected from May 17 to May 28, 2021, using self-report questionnaires. The collected data were analyzed using descriptive statistics, independent t-test, one-way analysis of variance, Scheffé test, Pearson's correlation coefficient analysis, and multiple regression using the SPSS/WIN 24.0. @*Results@#Job crafting was positively associated with work engagement (r=.55, p<.001) and quality of nursing services (r=.66, p<.001). Furthermore, work engagement had a mediating effect on the relationship between job crafting and quality of nursing services (Sobel test: Z=2.58, p=.010). These variables explained 45.0% of the variance in the quality of nursing services. @*Conclusion@#The impact of job crafting on the quality of nursing services among clinical nurses was mediated by work engagement. Therefore, to improve the quality of nursing services, it is necessary to develop an educational program to increase job crafting and work engagement.

Gambling Disorder Symptoms, Suicidal Ideation, and Suicide Attempts

Objective@#Gambling disorder (GD) patients have a higher suicide risk compared to the general population. The present study investigates the suicide-related risk factors of GD patients by analyzing GD diagnosis-related symptoms and suicide-related behaviors of subjects. @*Methods@#This study investigated which symptoms among GD diagnosis criteria are related to suicide risk in 142 patients diagnosed with GD. To analyze the relationship between GD symptoms and suicidal ideation and suicide attempt, the odds ratio (OR) was determined through multivariate logistic regression. @*Results@#The number of symptoms was significantly higher in the subjects who had suicidal ideation group and attempt group. In the cases of past suicide attempts, responses to withdrawal and escape questions were significantly higher; in the cases of ongoing suicidal ideation, responses to negative consequences and bailout questions were significantly higher. When depression was corrected, the ‘bailout’ item was, indicating that ‘bailout’ increased suicidal ideation (OR=4.937, 95% CI=1.009–24.164). In the suicide attempt group, ‘relieve’ item may increase suicide attempt (OR=6.978, 95% CI=1.300–35.562). @*Conclusion@#Past suicide attempts in GD patients correlated with withdrawal symptoms, and financial problem correlated with suicidal ideation. This suggests that evaluating suicide risk is important when evaluating GD patients, and evaluation of financial problems is important for GD patients with suicide risks.

Comparing Satisfaction and Importance of Nursing Care Nursing Work Environment, Nurse's Intention to Work between Comprehensive Nursing Care Unit and General Nursing Care Unit / 임상간호연구

PURPOSE: This study was aimed to identify the difference in satisfaction and importance of nursing care between patients in comprehensive nursing care unit (CNCU) and general nursing care unit (GNCU). It also confirms the difference between practice environment of nursing work and nurse's intention to work. METHODS: Nursing care satisfaction and importance levels were measured from 202 patients. Practice environment of nursing work and nurse's intention to work were measured from 54 nurses. RESULTS: The satisfaction level was higher in the CNCU in comparison to the GNCU (p < .001). There was no significant difference between the importance and satisfaction level of nursing care for patients at the CNCU (p=.973), whereas in the GNCU, patients' satisfaction level was lower than the importance level (p < .001). The score for practice environment for nursing work was higher in the CNCU than in the GNCU (t=3.34, p=.002). The nurse's intention to work in the CNCU was higher than that of the GNCU, but there was no statistically significant difference. CONCLUSION: Through the survey, the paper suggests that comprehensive nursing care is a service type that satisfies the nursing demand (importance) that patients consider important. Results from nurses showed no significant differences.

Prognostic assessment of sarcomatous histologic subtypes of ovarian carcinosarcoma

OBJECTIVE: Ovarian carcinosarcoma is a rare subtype of this disease that has not been thoroughly investigated. The aim of this study was to evaluate the prognostic factors and out comes in patients with ovarian carcinosarcoma. METHODS: All patients with histologically confirmed ovarian carcinosarcoma who were treated at Cheil General Hospital and Women's Healthcare Center between January 2000 and December 2015 were identified and analyzed. Data were extracted from medical records, and statistical analyses were performed to determine correlations between clinicopathological parameters and survival outcomes. RESULTS: Of the 822 patients diagnosed with ovarian cancer over 16 years, 11 (1.3%) had ovarian carcinosarcoma histology. Every patient underwent surgery as the initial treatment followed by intravenous adjuvant chemotherapy. Only 18.1% of cases were early stage (I or II) while 81.8% were advanced stage (III or IV) according to the FIGO (International Federation of Gynecology and Obstetrics) classification. Six cases were of the homologous subtype (54.5%) and five were of the heterologous subtype (45.5%). There was no significant difference in survival according to stage (P=0.24). The heterologous subtype and residual disease were associated with poor disease-free survival (P=0.02 and P=0.04) and overall survival (P=0.02 and P=0.04), On multivariate analysis, the histological subtype was an independent prognostic factor (P=0.02). CONCLUSION: Optimal cytoreduction without gross residual disease and a homologous subtype are favorable prognostic factors in terms of disease relapse and survival.

Comparing Results of Five Glomerular Filtration Rate-Estimating Equations in the Korean General Population: MDRD Study, Revised Lund-Malmö, and Three CKD-EPI Equations

BACKGROUND: Estimated glomerular filtration rate (eGFR) is a widely used index of kidney function. Recently, new formulas such as the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations or the Lund-Malmö equation were introduced for assessing eGFR. We compared them with the Modification of Diet in Renal Disease (MDRD) Study equation in the Korean adult population. METHODS: The study population comprised 1,482 individuals (median age 51 [42-59] yr, 48.9% males) who received annual physical check-ups during the year 2014. Serum creatinine (Cr) and cystatin C (CysC) were measured. We conducted a retrospective analysis using five GFR estimating equations (MDRD Study, revised Lund-Malmö, and Cr and/or CysC-based CKD-EPI equations). Reduced GFR was defined as eGFR <60 mL/min/1.73 m2. RESULTS: For the GFR category distribution, large discrepancies were observed depending on the equation used; category G1 (≥90 mL/min/1.73 m2) ranged from 7.4-81.8%. Compared with the MDRD Study equation, the other four equations overestimated GFR, and CysC-based equations showed a greater difference (-31.3 for CKD-EPI(CysC) and -20.5 for CKD-EPI(Cr-CysC)). CysC-based equations decreased the prevalence of reduced GFR by one third (9.4% in the MDRD Study and 2.4% in CKD-EPI(CysC)). CONCLUSIONS: Our data shows that there are remarkable differences in eGFR assessment in the Korean population depending on the equation used, especially in normal or mildly decreased categories. Further prospective studies are necessary in various clinical settings.

Analysis of the Factors that Affect Emergency Department Length of Stay in Patients with Orbital Wall Fracture

PURPOSE: The aim of this study un to determine factors that affect Emergency department (ED) Length of Stay (LOS) in patients with orbital wall fracture. METHODS: We retrospectively analyzed orbital fracture patients who visited our ED from January 1, 2012 to December 31, 2013. Patients'data, including sex, age, mechanism of injury, site of fracture, associated injury, physical finding, CT finding, and intra-ocular injuries were recorded. LOS was divided into three phases (Pre-consultation time, Consultation waiting time, Consultation time). We performed analysis to determine the factors associated with LOS. We also performed analysis to determine the factors associated with severe intraocular injury (SIOS). RESULTS: A total of 154 patients (160 eyes) were included. Orbital fractures were more frequent in males. The most common cause of orbital fracture was violence. LOS was 290.0 (IQR 200.0~465.0) min, pre-consultation time was 36.0 (IQR 22.0~61.0) min, consultation waiting time was 64.0 (IQR 34.0~128.0) min, and consultation time was 152.0 (IQR 87.0~245.0) min. Violence, alcohol consumption, consultation with plastic surgeon, and consultation with ophthalmologist showed association with prolonged LOS (p<0.001, p<0.001, p=0.04, p<0.001). Violence and alcohol consumption affected consultation waiting time (p<0.001, p<0.001) and consultation time (p=0.04, p<0.001). Consultation with a plastic surgeon and consultation with an ophthalmologist affected consultation time (p=0.03, p<0.001). Patients with symptoms including blindness, blurred vision, and visual field defect showed significant association with SIOS (Odd ratio=14.08). CONCLUSION: Violence, alcohol consumption, and consultations with specialists showed significant association with LOS.

Comparison of the Clinical Manifestations between Acute Vogt-Koyanagi-Harada Disease and Acute Bilateral Central Serous Chorioretinopathy

PURPOSE: To compare clinical, angiographic, and optical coherence tomographic characteristics between eyes with acute Vogt-Koyanagi-Harada (VKH) disease and eyes with acute bilateral central serous chorioretinopathy (CSC), and to demonstrate distinguishing features between the two diseases in confusing cases. METHODS: The medical records of 35 patients with VKH disease and 25 patients with bilateral CSC were retrospectively reviewed. Characteristics according to slit-lamp biomicroscopy, ophthalmoscopy, fundus photography, fluorescein angiography, indocyanine green angiography, and spectral-domain optical coherence tomography were compared between the two diseases. RESULTS: Five of 35 patients (10 of 70 eyes, 14.3%) with VKH disease were initially misdiagnosed as CSC patients, and six of 25 patients (12 of 50 eyes, 24%) with bilateral CSC were initially misdiagnosed as patients with VKH disease. Pigment epithelial detachment in CSC and optic disc hyperemia in VKH disease show the highest positive predictive values of 100% for each disease. CONCLUSIONS: Optic disc hyperemia in VKH disease and pigment epithelial detachment in bilateral CSC are the most specific clinical manifestations of each disease at initial patient presentation.

The Utility of p16INK4a and Ki-67 as a Conjunctive Tool in Uterine Cervical Lesions

BACKGROUND: Immunohistochemical staining for p16INK4a and Ki-67 has been used to improve the accuracy in making a diagnosis of the uterine cervix cancer on biopsy. This study was conducted to examine the usefulness of these markers in the pathological diagnosis based on cervical biopsy. METHODS: We selected a consecutive series of 111 colposcopically directed cervical punch biopsies. Using these biopsy samples, we performed an immunohistochemical staining for p16INK4a and Ki-67 to establish a diagnosis. The slides were circulated among four pathologists in a sequential order: the hematoxylin and eosin (H&E) slide, H&E slide and p16INK4a-stained slide, and H&E slide, p16INK4a- and Ki-67-stained slides. RESULTS: The overall rates of the concordance in the first, the second, and the third diagnoses were 77.5%, 82.0%, and 82.0%, respectively. The rate of the concordance in the diagnosis of cervical intraepithelial neoplasm (CIN) 2/3 was increased from 62.2% to 73.0%. But there was a variability in the rate of the revision of the diagnosis between the pathologists. With the application of criteria for interpreting the expressions of p16INK4a and Ki-67, benign and CIN 1 lesions showed a p16INK4a expression score of 0 or 1. But CIN 2 and CIN 3 lesions showed a p16INK4a expression score of 2 and 3, respectively. CONCLUSIONS: The immunostain for p16INK4a and Ki-67 might be useful in reducing an inter-observer variability. But criteria for interpreting both markers should be strictly applied.

Liquid-Based Pap Smear Findings of Uterine Cervical Lymphoma: Three Cases Report

Malignant lymphoma of the uterine cervix is rarely diagnosed by cytology because it presents as a subepithelial mass. We report three cases of diffuse large B-cell lymphoma in the uterine cervix with a description of liquid-based pap smear (LBP) findings. All patients were presented with cervical masses, but a suspicion of malignant lymphoma was made in only one case by preoperative LBP. The LBP of two cases showed several atypical lymphoid cells in a clear background. The other case revealed numerous atypical lymphoid cells in a necrotic background. Most tumor cells had an increased N/C ratio, round but focally irregular nuclei, coarse chromatin, and prominent nucleoli. Nuclear blebing, dimpling, and multi-lobulation were also found. Diagnosis of malignant lymphoma by LBP is usually more difficult than by conventional techniques, because of a sparse numbers of cells and the lack of necrotic background. However, well preserved morphological features and a better resolution of nuclear details could be the benefits of LBP.
