Objectives: This study analyzed the current state of community mental health programs in Korea to develop evidence-based criteria for these programs. Methods: Seventy community mental health facilities nationwide were surveyed about the scope of their operated mental health programs. Details, including program structure, staff expertise, standardization, and quality management, of the 511 programs submitted by the facilities as their representative programs were also analyzed to evaluate their efforts for evidence-based practice. Results: The average number of programs operated by community mental health welfare centers was 15.9. The most common programs were those related to serious mental illness (SMI), followed by child/adolescent mental health programs, early psychosis programs, and non-SMI adult mental health programs. In the case of community addiction management centers, there were 7.2 different addiction-related programs per center. Among the psychiatric rehabilitation facilities for SMI, the average number of programs for SMI was 13.1, with some programs for early psychosis. Of the 511 programs submitted as representative programs in their facilities, only 12.3% were judged to be good evidence-based programs. Conclusion More efforts by mental health professionals and governments are needed to implement evidence-based programs in Korea.

Background/Aims: Infliximab (IFX) has proven effective as rescue therapy in steroid-refractory acute severe ulcerative colitis (ASUC), however, the long-term real-world data are scarce. Our study aimed to assess the long-term treatment outcomes of IFX in a real-life cohort. Methods: We established a multicenter retrospective cohort of hospitalized patients with ASUC, who met Truelove and Witt’s criteria and received intravenous corticosteroid (IVCS) or IFX during index hospitalization between 2006 and 2016 in 5 university hospitals in Korea. The cohort was systematically followed up until colectomy, death or last follow-up visit. Results: A total of 296 patients were followed up for a mean of 68.9 ± 44.0 months. During index hospitalization, 49 patients were treated with IFX; as rescue therapy for IVCS failure in 37 and as first-line medical therapy for ASUC in 12. All patients treated with IFX avoided colectomy during index hospitalization. The cumulative rates of rehospitalization and colectomy were 20.4% and 6.1% at 3 months and 39.6% and 18.8% at the end of follow-up, respectively. Patients treated with IFX presented with significantly shorter colectomy-free survival than IVCS responders (P= 0.04, log-rank test). Both cytomegalovirus colitis and Clostridioides difficile infection (CDI) were the significant predictors of colectomy in the overall study cohort (hazard ratios of 6.57 and 4.61, respectively). There were no fatalities. Conclusions Our real-world cohort study demonstrated that IFX is an effective therapeutic option in Korean patients with ASUC, irrespective of IFX indication. Aggressive vigilance for cytomegalovirus colitis and CDI is warranted for hospitalized patients with ASUC.

OBJECTIVES: Pathogenic Vibrio species are widely distributed in warm estuarine and coastal environments, and can infect humans through the consumption of raw or mishandled contaminated seafood and seawater. For this reason, the distribution of these bacteria in South Korea was investigated.METHODS: Seawater samples were collected from 145 coastal area points in the aquatic environment in which Vibrio species live. Environmental data (i.e., water temperature, salinity, turbidity, and atmospheric temperature) was collected which may help predict the distribution of the species (data not shown). Seawater samples were filtered, and incubated overnight in alkaline peptone water, at 37°C. Using species-specific polymerase chain reaction methods, screening tests were performed for the hlyA, ctxA, vvhA, and tlh genes. Clones of pathogenic Vibrio species were isolated using 3 selective plating media.RESULTS: In 2017, total seawater isolation rates for Vibrio vulnificus, Vibrio cholerae (non-pathogenic, non-O1, non-O139 serogroups), and Vibrio parahaemolyticus were 15.82%, 13.18%, 65.80%, respectively. However, in 2018 isolation rates for each were 21.81%, 19.40%, and 70.05%, respectively.CONCLUSION: The isolation rates of pathogenic Vibrio species positively correlated with the temperature of seawater and atmosphere, but negatively correlated with salinity and turbidity. From 2017 to 2018, the most frequent seawater-isolated Vibrio species were V. parahaemolyticus (68.10 %), V. vulnificus (16.54%), and non-toxigenic V. cholerae (19.58%). Comprehensive monitoring, prevention, and control efforts are needed to protect the public from pathogenic Vibrio species.

The aim of the study is to investigate the association between cerebral white matter hyperintensity (WMH) and the functional improvement using the Korean version of Modified Barthel Index (K-MBI) score during inpatient stroke rehabilitation. One hundred sixty participants were divided into 2 groups based on the severity of WMH according to Fazekas scale: Mild WMH group was defined as patients with Fazekas scale 0 and 1, and severe WMH group was defined as Fazekas scale 2 and 3. Functional status was assessed using the K-MBI score, and functional gains were calculated from the K-MBI score. The absolute functional gain in mild WMH group was significantly higher compared to severe WMH group (p < 0.05). In addition, patients in mild WMH had higher absolute functional efficiency, rehabilitation effectiveness, and relative functional efficiency. In the generalized linear model analyses, there was an association between functional outcomes and severity of WMH. In this study, the severity and extent of WMH are significantly correlated with poor functional improvement in patients with ischemic stroke. The WMH could be considered as one of many factors that can influence functional recovery during rehabilitation of stroke.

PURPOSE: To evaluate the effects of intravitreal aflibercept injection in the treatment of submacular hemorrhage secondary to neovascular age-related macular degeneration (nAMD). METHODS: This retrospective, observational study included patients diagnosed with nAMD with submacular hemorrhage treated with intravitreal aflibercept monotherapy. A total of 54 eyes of 54 patients were treated with an initial series of three monthly intravitreal aflibercept injections followed by as-needed injections. At the 6 month follow-up, changes in best-corrected visual acuity (BCVA), central macular thickness (CMT), and submacular hemorrhage area (SMH) were evaluated. RESULTS: The mean preoperative BCVA was 0.79 ± 0.59 logMAR, which improved significantly to 0.53 ± 0.46 logMAR at 3 months and 0.48 ± 0.50 logMAR at 6 months (p < 0.001, in both). The CMT significantly decreased in all eyes: preoperative, 454.4 ± 131.5 µm, to 242.6 ± 39.7 µm at 6 months. The SMH was also reduced in all eyes: preoperative, 6.4 ± 4.8 disc areas (DAs) to 0.8 ± 1.4 DAs at 6 months. Ten eyes were diagnosed with typical nAMD (18.5%) and 44 eyes were diagnosed polypoidal choroidal vasculopathy (81.5%). There was no significant difference at 6 months in the visual outcomes of the subgroups. CONCLUSIONS: Intravitreal aflibercept monotherapy is well-tolerated as a treatment in maintaining or improving vision in patients with SMH secondary to nAMD.

PURPOSE: Macrolide-resistant Mycoplasma pneumoniae pneumonia (MPP) is characterized by prolonged fever and radiological progression despite macrolide treatment. Few studies have examined serum procalcitonin (PCT) level in children with MPP. We aimed to investigate the association of acute inflammation markers including PCT with clinical parameters in children with MPP. METHODS: A total of 147 children were recruited. The diagnosis of MPP relied on serial measurement of IgM antibody against mycoplasma and/or polymerase chain reaction. We evaluated the relationships between C-reactive protein (CRP), PCT, and lactate dehydrogenase (LDH) levels and white blood cell (WBC) counts, and clinical severity of the disease. We used multivariate logistic regression analysis to estimate the odds ratio for prolonged fever (>3 days after admission) and hospital stay (> 6 days), comparing quintiles 2–5 of the PCT levels with the lowest quintile. RESULTS: The serum PCT and CRP levels were higher in children with fever and hospital stay than in those with fever lasting ≤ 3 days after admission and hospital stay ≤ 6 days. CRP level was higher in segmental/lobar pneumonia than in bronchopneumonia. The LDH level and WBC counts were higher in children with fever lasting for >3 days before compared to those with fever lasting for ≤ 3 days. The highest quintile of PCT levels was associated with a significantly higher risk of prolonged fever and/or hospital stay than the lowest quintile. CONCLUSION: Serum PCT and CRP levels on admission day were associated with persistent fever and longer hospitalization in children with MPP.

PURPOSE: To compare the characteristics of optical coherence tomography in eyes with treatment-naïve typical neovascular age-related macular degeneration (typical nAMD), polypoidal choroidal vasculopathy (PCV), and retinal angiomatous proliferation (RAP). METHODS: One hundred fifty-three eyes newly diagnosed with exudative AMD were retrospectively collected. All study eyes were classified into three subtypes: typical nAMD, PCV, and RAP. Subfoveal choroidal thickness (SFCT) was measured using enhanced depth imaging optical coherence tomography (EDI-OCT). Central macular thickness (CMT) and other OCT features including intraretinal cystoid fluid and subretinal fluid were also evaluated in all eyes. SFCT, CMT and other OCT features were compared among the three subtypes of exudative AMD. RESULTS: Seventy-four eyes with typical nAMD, 55 eyes with PCV, and 24 eyes with RAP were included. SFCT was significantly thickest in PCV and thinnest in RAP (p < 0.001). RAP showed the thickest CMT and the highest frequency of intraretinal cystoid fluid (p = 0.004, p < 0.001, respectively). CONCLUSIONS: In patients with exudative AMD, different characteristics of OCT were observed according to the three subtypes. Identification of OCT characteristics could help differentiate the subtypes of exudative AMD.

PURPOSE: To evaluate changes in subfoveal choroidal thickness (SFCT) after patterned panretinal photocoagulation (PRP) using pattern scan laser (PASCAL) in patients with diabetic retinopathy. METHODS: This study included 39 patients (50 eyes) treated with patterned PRP using PASCAL and who were followed for at least 3 months. Patients were classified into 2 groups according to severity: severe non-proliferative diabetic retinopathy and proliferative diabetic retinopathy. SFCT was measured by enhanced depth imaging of spectral-domain optical coherence tomography. The change in SFCT was analyzed at 1 and 3 months after PRP. RESULTS: SFCT was 270.42 ± 61.44 µm before PRP, 264.52 ± 60.78 µm at 1 month, and 255.74 ± 56.89 µm at 3 months after PRP. Significant change of SFCT was found at 3 months after PRP. Central macular thickness was 275.56 ± 50.61 µm before PRP and increased to 295.18 ± 52.80 µm and 293.10 ± 57.24 µm at 1 and 3 months post-treatment, respectively. There were no significant differences between groups in SFCT at baseline or in the amount of change in SFCT after PRP. CONCLUSIONS: SFCT significantly decreased after patterned PRP using PASCAL.

Since Inoue et al introduced a specially designed balloon catheter for percutaneous mitral valvuloplasty (PMV) in 1984, the Inoue balloon catheter has been a popular device for the management of mitral stenosis. During the procedure several fatal complications, such as cardiac tamponade, perforation of a cardiac chamber, atrial septal defect, thromboembolism, mitral regurgitation and death have all been reported in the literature. There have also been several international reports regarding deformities of the Inoue balloon, but few reports in Korea. We recently experienced a case of an inflation failure of the distal portion of the Inoue balloon during a percutaneous mitral valvuloplasty in a 34 year old female patient with a tight mitral stenosis. To the best of our knowledge, a similar deformity of an Inoue balloon has never been reported in Korea.
