ABSTRACT

Purpose@#To evaluate the therapeutic effects and safety of oral spironolactone (SPRL) in patients with central serous chorioretinopathy (CSC). @*Materials and Methods@#The medical records and imaging data of patients diagnosed with CSC and treated with SPRL were retrospectively reviewed. Central macular thickness (CMT), subretinal fluid (SRF) height, subfoveal choroidal thickness (SFCT), and best-corrected visual acuity (BCVA) at baseline, at 1, 3, and 6 months, and at the last visit after the treatment were analyzed. @*Results@#In total, 103 patients with 107 eyes were included. The mean age of the patients was 51.5±9.3 years, and 77 (72.0%) were male. The mean follow-up duration was 48.6±40.2 weeks. The mean duration of oral SPRL therapy was 15.5±13.4 weeks. CMT, SRF height, and SFCT improved significantly at 1, 3, and 6 months after SPRL therapy and at the last follow-up. BCVA, however, showed no significant change at any time point. The rate of complete resolution of SRF at 1 month was higher in those with chronic CSC than in those with acute CSC (21.1% vs. 6.0%, respectively). Recurrence occurred in 14 (13.1%) eyes after the complete resolution of SRF. Older age (p=0.001), a greater number of previous intravitreal bevacizumab injections (p=0.006), and poor initial visual acuity (p=0.048) were associated with recurrence. No permanent adverse effects were observed. @*Conclusion@#Oral SPRL showed therapeutic benefits in patients with CSC in terms of SRF resolution, but relatively frequent recurrence was observed, especially in older patients.

ABSTRACT

Purpose@#To report a case of metastatic breast cancer to the optic nerve with a favorable response to an increased dose of intravitreal bevacizumab injection.Case summary: A 60-year-old female presented to our clinic with blurred vision in her left eye for 3 weeks. The patient had a history of intraductal breast cancer carcinoma, metastasized to the mediastinum lymph nodes, liver, and bone and had received palliative chemotherapy and radiotherapy for 16 months. At her first presentation, best-corrected visual acuity of the left eye was 20/50 and the intraocular pressure was 11 mmHg. A yellowish elevated mass with hemorrhage at the optic disc with peripapillary swelling was observed in the left eye. Fluid at the subperipapillary and subfoveal areas and choroidal thickening with folds were observed with optic coherence tomography. The patient was diagnosed as having breast cancer metastasis to the optic nerve head. Three monthly intravitreal bevacizumab injections (0.05 mL, 1.25 mg) were administered, but showed limited effect. Two more intravitreal bevacizumab injections having twice the concentration of the previous dose (0.1 mL, 2.50 mg) were given. Tumor infiltration of the optic nerve head decreased, and serous retinal detachment subsided. No malignant cancer cells were detected in the anterior chamber. @*Conclusions@#We report a rare case of breast cancer metastasis to the optic nerve. Administering intravitreal bevacizumab injections with twice the dosage concentration could be an alternative treatment option, to alleviate exudative retinal detachment associated with metastatic tumor progression to the optic nerve head.

ABSTRACT

Background@#The association of invasive tracheobronchial aspergillosis (ITBA) with invasive pulmonary aspergillosis (IPA) is not well established. We aimed to compare clinical characteristics between patients who exhibited ITBA with IPA and those who exhibited isolated ITBA (iITBA). Additionally, the usefulness of serum or bronchial galactomannan (GM) tests in diagnosing ITBA was evaluated. @*Methods@#This retrospective single-center case-control study was conducted over a period of 4 years. Fifteen patients were enrolled after confirming the presence of ITBA using bronchoscopy-guided biopsy (iITBA, 7 vs. ITBA+IPA, 8). Clinical characteristics of patients and results obtained from serum or bronchial GM tests were compared between the two groups. Mortality was assessed using data collected from a 6-month follow-up period. @*Results@#The ITBA+IPA group showed a higher prevalence of hematologic malignancy (75% vs. 14%, p=0.029), a greater number of patients with multiple bronchial ulcers (75% vs. 14%, p=0.029), lower platelet counts (63,000/μL vs. 229,000/μL, p<0.001), and a mortality rate which was significantly higher (63% vs. 0%, p=0.026) than the iITBA group. In the ITBA+IPA group, 57% of patients tested positive according to the serum GM assay, whereas in the iITBA group, all patients tested negative (p=0.070). The bronchial GM level was high in both groups, but there was no significant difference between them. @*Conclusion@#Patients with ITBA+IPA had a greater number of hematologic malignancies with lower platelet counts and a poorer prognosis than patients diagnosed with iITBA. Findings obtained from bronchoscopy and bronchial GM tests were more useful in diagnosing ITBA than the serum GM test results.

ABSTRACT

Purpose@#To evaluate the therapeutic efficacy and safety of intravitreal dexamethasone implant in non-infectious uveitis (divided into anterior, intermediate, posterior, and panuveitis types). @*Methods@#The medical records of patients who received intravitreal dexamethasone implants between June 2013 and January 2018 at a tertiary referral hospital were analyzed retrospectively. @*Results@#A total of 38 eyes of 36 patients were included. All patients were diagnosed with non-infectious uveitis and received intravitreal dexamethasone implants. The mean age was 55.6 years, and 18 (50.0%) patients were male. In total, 6 (15.8%) eyes were diagnosed with anterior uveitis, 5 (13.2%) with intermediate uveitis, 16 (42.1%) with posterior uveitis, and 11 (28.9%) with panuveitis. Patients with all types of uveitis showed significant improvement in clinical outcomes after intravitreal dexamethasone implant. Three eyes showed increased intraocular pressure, while four showed cataract progression and thus received cataract extraction after injection. Seventeen (44.7%) eyes relapsed an average of 1.18 ± 0.39 times and received additional treatments. @*Conclusions@#Non-infectious uveitis patients showed significant improvement in clinical outcomes after intravitreal dexamethasone implant injection. However, care is required during injection due to the risk of recurrence, as well as side effects such as increased intraocular pressure and cataract progression.

ABSTRACT

Objectives@#In this study, we aimed to investigate the cardiopulmonary resuscitation (CPR)-related knowledge, attitude, and performance among dental hygienists working in the hospitals. We believe that it is important to develop CPR education programs that would enable dental hygienists to offer accurate and timely aid in emergency situations. @*Methods@#From June 20 to August 20, 2019, 220 dental hygienists at seven selected dental hospitals located in Gwangju Metropolitan City and Jeollanam-do, South Korea were requested to fill a questionnaire as part of a survey. The data regarding the general characteristics, CPR-related characteristics, and CPR-related knowledge, approach, and performance were collected, and analyzed using independent t-tests, oneway analysis of variance (ANOVA), Pearson’s correlation coefficient, and simple regression analysis using the SPSS Windows ver. 25.0. @*Results@#Correlation analysis revealed that high CPR-related knowledge and a more positive approach towards CPR are both associated with high confidence in performing CPR (r=0.37, r=0.415, r=0.605). Furthermore, factors, such as high CPR-related knowledge, positive attitude towards CPR, knowledge regarding the location of automated external defibrillators (AEDs) in the hospital, and AED training experience significantly affects the CPR-related performance. @*Conclusions@#Therefore, it is important to develop systematic and beneficial educational programs and provide and update educational material regularly in dental hospitals with an aim to improve CPR-related knowledge and attitude among the dental hygienists.

ABSTRACT

Purpose@#We sought to evaluate the long-term outcomes for patients with exudative age-related macular degeneration (AMD) undergoing vitrectomy for breakthrough vitreous hemorrhage and to investigate possible prognostic factors. @*Methods@#Consecutive patients treated at two high-volume referral-based tertiary hospitals between July 2006 and Decem-ber 2019 were retrospectively reviewed. Surgery was performed using the standard three-port vitrectomy. The primary out-come was the change in best-corrected visual acuity (BCVA) over long-term follow-up, while secondary outcomes included the assessment of possible prognostic factors. @*Results@#Among 50 eyes from 50 patients included in this study, 23 (46%) were diagnosed with polypoidal choroidal vascu-lopathy (PCV) and 27 (54%) were diagnosed with neovascular AMD. Preoperative vision at the time of vitreous hemorrhage onset was 20 / 3,027 (logarithm of the minimum angle of resolution [logMAR], 2.18 ± 0.34). At 12 months after surgery, the mean BCVA improved to 20 / 873 (logMAR, 1.64 ± 0.76; p < 0.001). At 24 months, the BCVA was 20 / 853 (logMAR, 1.63 ± 0.75; p < 0.001). Univariate analysis revealed that older age (odds ratio [OR], 0.879; p = 0.007] and the presence of submac-ular hemorrhage (OR, 0.081; p= 0.022) were factors associated with a poor 2-year visual outcome. Multivariable regression showed that older age (OR, 0.876; p= 0.026) and neovascular AMD (as compared with PCV) (OR, 0.137; p= 0.014) were significant negative factors influencing the 2-year visual outcome. The mean injection interval prior to vitrectomy was 4.53 months, which extended to 27.64 months after vitrectomy ( p = 0.028). @*Conclusions@#Younger age, the absence of submacular hemorrhage, and PCV type were associated with a favorable 2-year visual outcome after vitrectomy for vitreous hemorrhage in patients with exudative AMD. Overall, vitrectomy resulted in im-proved visual acuity and patients showed a decreased need for anti-vascular endothelial growth factor therapy thereafter.

ABSTRACT

We retrospectively reviewed patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections who wereadmitted to an intensive care unit in Daegu, South Korea. The outcomes of patients who did (cases) or did not (controls) receivedarunavir-cobicistat (800–150 mg) therapy were compared. Fourteen patients received darunavir-cobicistat treatment, and 96 receivedother antiviral therapy (controls). Overall, the darunavir-cobicistat group comprised patients with milder illness, and thecrude mortality rate of all patients in the darunavir-cobicistat group was lower than that in the controls [odds ratio (OR) 0.20, 95%confidence interval (CI) 0.04–0.89, p=0.035]. After 1:2 propensity-score matching, there were 14 patients in the darunavir-cobicistatgroup, and 28 patients in the controls. In propensity score-matched analysis, the darunavir-cobicistat group had lower mortalitythan the controls (OR 0.07, 95% CI 0.01–0.52, p=0.009). In conclusion, darunavir-cobicistat therapy was found to be associatedwith a significant survival benefit in critically ill patients with SARS-CoV-2 infection.

ABSTRACT

Although some information on the epidemiology of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and a few selectedcases has been reported, data on the clinical characteristics and outcomes of patients hospitalized therewith in South Koreaare lacking. We conducted a retrospective single-center study of 98 consecutive hospitalized patients with confirmed SARS-CoV-2infection at Yeungnam University Medical Center in Daegu, South Korea. Sixty patients were women (61.2%), and the mean agewas 55.4±17.1 years. Thirteen patients (13.3%) were treated in the intensive care unit (ICU). The mean interval from symptom onsetto hospitalization was 7.7±4.5 days. Patients who received ICU care were significantly older and were more likely to have diabetesmellitus. The National Early Warning Score on the day of admission was significantly higher in patients requiring ICU care. Acuterespiratory distress syndrome (13/13 patients; 100%), septic shock (9/13; 69.2%), acute cardiac injury (9/13; 69.2%), and acute kidneyinjury (8/13; 61.5%) were more common in patients who received ICU care. All patients received antibiotic therapy, and most(97/98 patients; 99.0%) received antiviral therapy (lopinavir/ritonavir). Hydroxychloroquine was used in 79 patients (80.6%), andglucocorticoid therapy was used in 18 patients (18.4%). In complete blood counts, lymphopenia was the most common finding(40/98 patients; 40.8%). Levels of all proinflammatory cytokines were significantly higher in ICU patients. As of March 29, 2020, themortality rate was 5.1%. Here, we report the clinical characteristics and laboratory findings of SARS-CoV-2 patients in South Koreaup to March 29, 2020.

ABSTRACT

Background@#To determine the role of diabetes mellitus (DM) in the coronavirus disease 2019 (COVID-19), we explored the clinical characteristics of patients with DM and compared risk factors such as age, glycemic control, and medications to those without DM. @*Methods@#This was a retrospective cohort study of 117 confirmed patients with COVID-19 which conducted at a tertiary hospital in Daegu, South Korea. The primary outcome was defined as the severe and critical outcome (SCO), of which the composite outcomes of acute respiratory distress syndrome, septic shock, intensive care unit care, and 28-day mortality. We analyzed what clinical features and glycemic control-related factors affect the prognosis of COVID-19 in the DM group. @*Results@#After exclusion, 110 participants were finally included. DM patients (n=29) was older, and showed higher blood pressure compared to non-DM patients. DM group showed higher levels of inflammation-related biomarkers and severity score, and highly progressed to SCO. After adjustment with other risk factors, DM increased the risk of SCO (odds ratio [OR], 10.771;p <0.001). Among the DM patients, SCO was more prevalent in elderly patients of ≥70 years old and age was an independent risk factor for SCO in patients with DM (OR, 1.175; p =0.014), while glycemic control was not. The use of medication did not affect the SCO, but the renin-angiotensin system inhibitors showed protective effects against acute cardiac injury (OR, 0.048; p=0.045). @*Conclusion@#The COVID-19 patients with DM had higher severity and resulted in SCO. Intensive and aggressive monitoring of COVID-19 clinical outcomes in DM group, especially in elderly patients is warranted.

ABSTRACT

Since the first case was contracted by coronavirus disease-19 (COVID-19) in Daegu, Korea in February 2020, about 6,800 cases and 130 deaths have been reported on April 9, 2020. Recent studies have reported that patients with diabetes showed higher mortality and they had a worse prognosis than the group without diabetes. In poorly controlled patients with diabetes, acute hyperglycemic crises such as diabetic ketoacidosis (DKA) or hyperosmolar hyperglycemic state (HHS) also might be precipitated by COVID- 19. Thus, intensive monitoring and aggressive supportive care should be needed to inadequately controlled patients with diabetes and COVID-19 infection. Here, we report two cases of severe COVID-19 patients with acute hyperglycemic crises in Korea.

ABSTRACT

Background@#Since its first detection in December 2019, coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 infection has spread rapidly around the world. Although there have been several studies investigating prognostic factors for severe COVID-19, there have been no such studies in Korea. @*Methods@#We performed a retrospective observational study of 110 patients with confirmed COVID-19 hospitalized at a tertiary hospital in Daegu, Korea. Demographic, clinical, laboratory, and outcome data were collected and analyzed. Severe disease was defined as a composite outcome of acute respiratory distress syndrome, intensive care unit care, or death. @*Results@#Diabetes mellitus (odds ratio [OR], 19.15; 95% confidence interval [CI], 1.90–193.42; P = 0.012), body temperature ≥ 37.8°C (OR, 10.91; 95% CI, 1.35–88.36; P = 0.025), peripheral oxygen saturation 6.3 (OR, 56.84; 95% CI, 2.64–1,223.78, P = 0.010) at admission were associated with higher risk of severe COVID-19. The likelihood of development of severe COVID-19 increased with an increasing number of prognostic factors. @*Conclusion@#In conclusion, we found that diabetes mellitus, body temperature ≥ 37.8°C, peripheral oxygen saturation 6.3 are independent predictors of severe disease in hospitalized COVID-19 patients. Appropriate assessment of prognostic factors and close monitoring to provide the necessary interventions at the appropriate time in high-risk patients may reduce the case fatality rate of COVID-19.

ABSTRACT

Background@#Medical professionals who experience patient safety incidents (PSIs) are vulnerable to emotional pain and other difficulties; such individuals are referred to as “second victims.” This study quantitatively examines the characteristics of physicians’ experiences of PSIs, along with the consequent difficulties and levels of post-traumatic stress disorder (PTSD), and post-traumatic embitterment disorder (PTED) regarding the events. @*Methods@#An anonymous, self-report online survey was administered to physicians. This collected information regarding PSI characteristics (e.g., type, severity of harm) and impact (e.g., sleep disorder, consideration of career change), as well as participants' socio-demographic characteristics. Meanwhile, to quantitatively assess PSI impacts, PTSD and PTED scales were also administered. PSI characteristics and impacts were analyzed using frequency analysis, and the differing effects of indirect and direct PSI experience regarding consequent difficulties were analyzed using chi-square tests. Factors associated with PTSD and PTED scores were identified using linear regression. @*Results@#Of 895 physicians, 24.6% and 24.0% experienced PSI-induced sleep disorder and eating disorder, respectively. Moreover, 38.9% reported being overly cautious in subsequent similar situations, and 12.6% had considered changing jobs or career. Sleep disorder was significantly more common among participants who directly experienced a PSI (32.8%) than among those with indirect experience (15.3%; P < 0.001). Linear regression showed that indirectly involved physicians had a lower mean PTSD score (by 8.44; 95% confidence interval, −12.28 to −4.60) than directly involved physicians. @*Conclusion@#This study found that many physicians experience PSI-induced physical symptoms and behavioral responses, and that the severity of these symptoms varies depending on the type of incident and degree of harm involved. Our findings can provoke more active discussion regarding programs for supporting second victims, and can also encourage the establishing of a system for addressing PSIs that have already occurred, such as through disclosure of PSIs.

ABSTRACT

Background@#The prevalence of impaired fasting glucose (IFG) in Korea is increasing. Few studies have investigated the relationship between handgrip strength (HGS) and type 2 diabetes among Koreans; however, no study has investigated the relationship between IFG and HGS among Koreans. Therefore, we examined the relationship between relative IFG and HGS to evaluate HGS as a marker of prediabetes. @*Methods@#This cross-sectional study analyzed data from participants aged 20 years or older (n=9,190) who did not have diabetes and had had their body mass index, fasting plasma glucose (FPG), and HGS measured in the 2016–2017 Korea National Health and Nutrition Examination Survey. The association between relative HGS and IFG was analyzed using complex sample logistic regression analyses after adjusting for age, education, strengthening exercise, aerobic exercise, smoking, excessive drinking, and chronic diseases. @*Results@#The prevalence of IFG was 31.5 (0.9)% and 19.6 (0.7)% for men and women, respectively. According to the increase in quartile of relative HGS, FPG and HbA1c significantly decreased in both men and women (Ptrend<0.001). In multivariate logistic regression, the odds of IFG significantly decreased with the increase in quartile of relative HGS in both men and women (Ptrend=0.001 for men, Ptrend=0.002 for women). @*Conclusion@#This population-based, nationally representative study suggests that higher relative HGS is associated with a decreased risk of IFG for both men and women.

ABSTRACT

BACKGROUND@#Chronic cough is defined as a cough lasting more than 8 weeks and socio-economic burden of chronic cough is enormous. The characteristics of chronic cough in Korea are not well understood. The Korean Academy of Tuberculosis and Respiratory Diseases (KATRD) published guidelines on cough management in 2014. The current study evaluated the clinical characteristics of chronic cough in Korea and the efficacy of the KATRD guidelines.@*METHODS@#This was a multi-center, retrospective observational study conducted in Korea. The participants were over 18 years of age. They had coughs lasting more than 8 weeks. Subjects with current pulmonary diseases, smokers, ex-smokers with more than 10 pack-years or who quit within the past 1 year, pregnant women, and users of cough-inducing medications were excluded. Evaluation and management of cough followed the KATRD cough-management guidelines.@*RESULTS@#Participants with chronic cough in Korea showed age in the late forties and cough duration of more than 1 year. Upper airway cough syndrome was the most common cause of cough, followed by cough-variant asthma (CVA). Gastro-esophageal reflux diseases and eosinophilic bronchitis were less frequently observed. Following the KATRD cough-management guidelines, 91.2% of the subjects improved after 4 weeks of treatment. Responders were younger, had a longer duration of cough, and an initial impression of CVA. In univariate and multivariate analyses, an initial impression of CVA was the only factor related to better treatment response.@*CONCLUSION@#The causes of chronic cough in Korea differed from those reported in other countries. The current Korean guidelines proved efficient for treating Korean patients with chronic cough.

ABSTRACT

Purpose@#To evaluate the therapeutic effects and safety of oral spironolactone (SPRL) in patients with central serous chorioretinopathy (CSC). @*Methods@#Medical records and imaging data from consecutive patients diagnosed with CSC and treated with SPRL were reviewed. Changes in central macular thickness (CMT), subretinal fluids (SRF), subfoveal choroidal thickness (SFCT), and best corrected visual acuity (BCVA) were measured at baseline and follow-up visits. Follow-up visits were performed at 1, 3, 6, and 12 months after treatment. The patients were divided into two groups; acute and chronic, and the therapeutic outcomes were compared. The occurrence of side effects and recurrence after complete resolution of SRF were also assessed. @*Results@#A total of 42 patients with 45 eyes were included. CMT and SRF after using SPRL improved significantly at 1, 3, 6, and 12 months and SFCT improved at 3, 6, and 12 months. However, BCVA showed no significant change at any time. Acute patients showed similar results. However, in chronic patients, CMT showed significant differences at 1 and 3 months, SRF at 1 and 6 months, and SFCT at 6 months. A total of 15.6%, 38.2%, 45.8%, and 50.0% of eyes showed complete resolution of SRF at each follow-up period, respectively, and 8.9% of eyes showed recurrence after complete resolution. Two male patients experienced gynecomastia and one patient showed mild elevation of serum creatinine. @*Conclusions@#Our study supported the therapeutic benefits of SPRL in patients with CSC, especially in anatomical structures. However, careful observation is required because of side effects and recurrence after complete resolution.

The occurrence of side effects and recurrence after complete resolution of SRF were also assessed. @*Results@#A total of 42 patients with 45 eyes were included. CMT and SRF after using SPRL improved significantly at 1, 3, 6, and 12 months and SFCT improved at 3, 6, and 12 months. However, BCVA showed no significant change at any time. Acute patients showed similar results. However, in chronic patients, CMT showed significant differences at 1 and 3 months, SRF at 1 and 6 months, and SFCT at 6 months. A total of 15.6%, 38.2%, 45.8%, and 50.0% of eyes showed complete resolution of SRF at each follow-up period, respectively, and 8.9% of eyes showed recurrence after complete resolution. Two male patients experienced gynecomastia and one patient showed mild elevation of serum creatinine. @*Conclusions@#Our study supported the therapeutic benefits of SPRL in patients with CSC, especially in anatomical structures. However, careful observation is required because of side effects and recurrence after complete resolution.
