Music from noise-canceling headphones is beneficial against anxiety in male bladder cancer patients undergoing follow-up cystoscopy: A prospective randomized trial. Urol Int 2024:000539312. [PMID: 38735280 DOI: 10.1159/000539312] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2024] [Accepted: 04/13/2024] [Indexed: 05/14/2024]
Abstract
INTRODUCTION Bladder cancer, with a greater incidence in males than in females, requires frequent cystoscopies. We aim to evaluate the effect of music played through noise-canceling headphones on male bladder cancer patients during follow-up cystoscopy. METHODS A total of 160 male bladder cancer patients undergoing follow-up flexible cystoscopy were randomly divided into the noise-canceling headphones without music group and the noise-canceling headphones with music group (groups 1 and 2, respectively; n = 80 per group). The patients' clinical characteristics were examined and objective and subjective measurements were compared before and after cystoscopy. The primary outcomes that were evaluated included the visual analog scale (VAS, 0-10) and the state-trait anxiety inventory (STAI, 20-80). Other outcomes, including vital signs and scores for assessing satisfaction and the willingness to repeat the procedure, were also examined. RESULTS The characteristics of the patients in groups 1 and 2, and their pre-cystoscopy status, did not differ significantly. Although post-cystoscopy vital signs for the objective parameters and VAS pain scores were similar between the groups, subjective parameters were not. When compared with group 1, post-cystoscopy STAI-state scores were significantly lower in group 2, whereas patients' satisfaction scores and the willingness to repeat the procedure were significantly higher in group 2 (p = 0.002, 0.001, and 0.001, respectively). Additionally, in group 2, STAI-state scores changed significantly after the procedure when compared with before the procedure (p = 0.002). CONCLUSION In male bladder cancer patients, music from noise-canceling headphones might have reduced anxiety and improved satisfaction and the willingness to repeat cystoscopy.

Spiritual nursing education programme for nursing students in Korea: a systematic review and meta-analysis. BMC Nurs 2024; 23:310. [PMID: 38715058 PMCID: PMC11077795 DOI: 10.1186/s12912-024-01961-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2023] [Accepted: 04/22/2024] [Indexed: 05/12/2024] Open
Abstract
PURPOSE This study conducts a systematic review and meta-analysis to understand the characteristics and contents of studies on spiritual nursing education programmes and their effects. METHODS The literature search included five databases (RISS, KISS, DBpia, Science ON, and KmBase) published in South Korea until September 30, 2021. Nine studies were included in the final review, with six for the meta-analysis using the RevMan 5.4. 1 programme. The programmes targeted nursing students and nurses in the RN-BSN course and employed methods such as lecturing, discussions, and case presentations. The contents focused on self-spirituality awareness, spirituality-related concepts, understanding others' spirituality, and the process and application of spiritual nursing. RESULTS The meta-analysis revealed statistically significant effects on spiritual nursing competencies, spirituality, spiritual well-being, existential well-being, and spiritual needs, except self-esteem. Spiritual nursing education was effective in enhancing spiritual nursing competencies. CONCLUSION The study confirmed that spiritual nursing education effectively improves spiritual nursing competency, indicating a need for increased focus and administrative and financial support for such education in schools and hospitals. Furthermore, future studies should employ randomised experimental designs to examine the effects of online education programmes with short training time on clinical nurses in hospitals.

Health and medical experience of migrant workers: qualitative meta-synthesis. Arch Public Health 2024; 82:27. [PMID: 38429652 PMCID: PMC10905938 DOI: 10.1186/s13690-024-01254-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Accepted: 02/14/2024] [Indexed: 03/03/2024] Open
Abstract
BACKGROUND Migrant workers in Korea are contributing to economic development by resolving labour shortages due to the increase in the ageing population, and they have become necessary and important in the Korean economy. However, long working hours, poor working conditions, and cultural differences can cause migrant workers to experience disadvantages in using health and medical services. Therefore, this study aimed to understand and analyse the health and medical service experience of migrant workers in Korea by reviewing previous studies in order to improve their health and access to medical services. METHOD The qualitative meta-synthesis method suggested by Thomas and Harden was used. The key question for searching the literature is 'What is the status of the use of health and medical service by migrant workers in Korea and the attributes that affect them?' Five electronic databases (RISS, KCI, KISS, Science ON, and KMbase) were searched for Korean literature published in academic journals until 6 November 2022 using a combination of "migrant worker or foreign worker or foreign labourer or migrant" and "medical or health" in Korean. RESULTS A total of nine studies out of 1,006 were included in the review after methodological quality assessment using the Critical Appraisal Skills Program (CASP). The results of studies were synthesised into three themes and ten sub-themes: 'Personal factors' of personal health beliefs and the financial burden of healthcare costs; 'Cultural factors' of cultural differences in the lifestyle, cultural differences in the healthcare environment, and traditional medicine in the country; and 'Socio-institutional factors' of poor and difficult working environment, insufficient information about medical institutions, policies with a lack of practical applicability, systems of healthcare institutions, and healthcare services usage. CONCLUSIONS This study identified the experiences of migrant workers in using health and medical care services. The results of this study can be used as a basis for improving the health of migrant workers and access to healthcare services. Based on the results of this study, it is necessary to improve the health management ability of migrant workers by developing a health management platform that can support Korean medical information and provide professional and accurate self-health management information.

Treatment Outcome of Olfactory Neuroblastoma: A Multicenter Study by the Korean Sinonasal Tumor and Skull Base Surgery Study Group. Clin Exp Otorhinolaryngol 2024:ceo.2023.00089. [PMID: 38404243 DOI: 10.21053/ceo.2023.00089] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2023] [Accepted: 02/26/2024] [Indexed: 02/27/2024] Open
Abstract
Objectives Due to the rarity of olfactory neuroblastoma (ONB), there is an ongoing debate about optimal treatment strategies, especially for early staged or locally advanced cases. Therefore, our study aims to explore experiences from multiple centers, focusing on factors that influence the oncological outcomes of ONB. Methods We retrospectively analyzed 195 ONB patients treated at nine tertiary hospitals in South Korea between December 1992 and December 2019. Kaplan-Meier survival analysis was used to evaluate oncological outcomes, and the Cox proportional hazards regression model was employed to analyze prognostic factors for survival outcomes. Furthermore, we conducted 1:1 nearest-neighbor matching to investigate differences in clinical outcomes according to the use of neoadjuvant chemotherapy. Results In our cohort, the 5-year overall survival rate (OS) was 78.6%, and the 5-year disease-free survival rate (DFS) was 62.4%. The Cox proportional hazards model revealed that the mKadish stage and Dulguerov T status were significant for DFS, while the mKadish stage and Hyams grade were identified as prognostic factors for OS. The subgroup analyses indicated a trend toward improved 5-year DFS with dural resection in mKadish A and B cases, even though that result was statistically insignificant. Induction chemotherapy did not provide a survival benefit in this study after matching for the mKadish stage and nodal status. Conclusion Clinical staging and pathologic grading are important prognostic factors in ONB. Dural resection in mKadish A and B did not show a significant survival benefit. Induction chemotherapy did not show a survival benefit, even after stage matching.

Immediate-start peritoneal dialysis without break-in-period: an 18-year retrospective cohort study on patient survival. Kidney Res Clin Pract 2024:j.krcp.23.103. [PMID: 38389148 DOI: 10.23876/j.krcp.23.103] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2023] [Accepted: 11/08/2023] [Indexed: 02/24/2024] Open
Abstract
Background Immediate-start peritoneal dialysis (ISPD) is an effective renal replacement therapy that can prevent central venous catheterization due to its immediate initiation of peritoneal dialysis (PD) after catheter insertion without a break-in period. This study aimed to investigate the effect of ISPD on long-term patient survival. Methods In this retrospective single-center cohort study, 178 consecutive patients who started PD from August 2005 to March 2023 were enrolled, from whom 144 patients with ISPD were analyzed. PD was initiated without a break-in period within 24 hours of catheter insertion using percutaneous needle-guidewire technique. The primary outcome was patient survival, estimated using the Kaplan-Meier method. A Cox proportional hazard regression model was used to identify factors independently associated with patient survival. Results The median follow-up period was 4.00 years (interquartile range, 1.23‒5.75 years). The mean age of patients was 61.6 ± 13.6 years; 58 patients (40.3%) were male and 93 patients (64.6%) were diabetic. Overall patient survival rates at 1, 3, 5, and 10 years were 98.5%, 93.5%, 92.1%, and 65.6%, respectively. The technique survival rates at 1, 3, 5, and 10 years were 88.1%, 74.9%, 63.2%, and 40.2%, respectively. The peritonitis-free survival rates at 1, 3, 5, and 10 years were 92.3%, 76.0%, 59.4%, and 28.0%, respectively. In the multivariate analysis, diabetes was the only factor associated with patient survival and technique survival. Conclusion Our study demonstrated that patient survival and technique survival rates were relatively high in ISPD patients who were catheterized using percutaneous needle-guidewire technique.

Abstract
This prospective, 12-center study investigated the etiology and clinical characteristics of acute viral hepatitis (AVH) during 2020-2021 in South Korea, and the performance of different diagnostic methods for hepatitis E virus (HEV). We enrolled 428 patients with acute hepatitis, of whom 160 (37.4%) were diagnosed with AVH according to predefined serologic criteria. The clinical data and risk factors for AVH were analyzed. For hepatitis E patients, anti-HEV IgM and IgG were tested with two commercial ELISA kits (Abia and Wantai) with HEV-RNA real-time RT-PCR. HAV, HEV, HBV, HCV, Epstein-Barr virus (EBV), cytomegalovirus, and herpes simplex virus accounted for AVH in 78.8% (n = 126), 7.5% (n = 12), 3.1% (n = 5), 1.9% (n = 3), 6.9% (n = 11), 1.2% (n = 2), and 0.6% (n = 1) of 160 patients (median age, 43 years; men, 52.5%; median ALT, 2144 IU/L), respectively. Hospitalization, hemodialysis, and intensive care unit admission were required in 137 (86.7%), 5 (3.2%), and 1 (0.6%) patient, respectively. Two patients developed acute liver failure (1.3%), albeit without mortality or liver transplantation. Ingestion of uncooked clams/oysters and wild boars' blood/bile was reported in 40.5% and 16.7% of patients with HAV and HEV, respectively. The concordance rate between the anti-HEV-IgM results of both ELISA kits was 50%. HEV RNA was detected in only 17% of patients with HEV. The diagnosis of HEV needs clinical consideration due to incomplete HEV diagnostics.

Abstract
PURPOSE Cluster analyses on inflammatory markers of chronic rhinosinusitis (CRS) in Asians from multicenter data are lacking. This multicenter study aimed to identify the endotypes of CRS in Koreans and to evaluate the relationship between the endotypes and clinical parameters. METHODS Nasal tissues were obtained from patients with CRS and controls who underwent surgery. The endotypes of CRS were investigated by measuring interleukin (IL)-5, interferon (IFN)-γ, IL-17A, IL-22, IL-1β, IL-6, IL-8, matrix metalloproteinase-9, eotaxin-3, eosinophil cationic protein, myeloperoxidase (MPO), human neutrophil elastase (HNE), periostin, transforming growth factor-β1, total immunoglobulin E (IgE), and staphylococcal enterotoxin (SE)-specific IgE. We performed hierarchical cluster analysis and evaluated the phenotype, comorbidities, and Lund-Mackay computed tomography (LM CT) score in each cluster. RESULTS Five clusters and 3 endotypes were extracted from 244 CRS patients: cluster 1 had no upregulated mediators compared to the other clusters (mild mixed inflammatory CRS); clusters 2, 3, and 4 had higher concentrations of neutrophil-associated mediators including HNE, IL-8, IL-17A, and MPO (T3 CRS); and cluster 5 had higher levels of eosinophil-associated mediators (T2 CRS). SE-specific IgE was undetectable in T3 CRS and had low detectable levels (6.2%) even in T2 CRS. The CRS with nasal polyps (CRSwNP) phenotype and LM CT scores showed no significant differences between T2 and T3 CRS, while the incidence of comorbid asthma was higher in T2 CRS than T3 CRS. In T3 clusters, higher levels of neutrophilic markers were associated with disease severity and CRSwNP phenotype. CONCLUSIONS In Koreans, there is a distinct T3 CRS endotype showing a high proportion of CRSwNP and severe disease extent, along with T2 CRS.

Abstract
Cavernous sinus thrombosis (CST) is a rare but life-threatening infectious disease whose diagnosis and treatment are challenging. CST can result in ocular and neurologic morbidities, as well as fatal systemic complications due to systemic thrombus. Occasionally, these clinical symptoms can be a result of contralateral sinusitis. A 75-year-old female presented with severe headache and fever. Magnetic resonance imaging revealed a multifocal filling defect in both cavernous sinuses, with heterogeneous enhancement and thrombosis of the right superior ophthalmic vein. Intravenous antibiotic was administered, and endoscopic sinus surgery was performed. The patient was discharged 40 days after admission and there were no neurologic symptoms and no evidence of sequelae during the 10-month follow-up. Symptoms of CST on the contralateral side are often missed, which delays initiation of appropriate treatment. When CST secondary to paranasal sinusitis is diagnosed, clinicians should consider contralateral as well as ipsilateral infection of the paranasal sinus. Preventing disease progression and complications through early and aggressive antibiotic administration along with sinus surgery is crucial.

Abstract
BACKGROUND Currently, the number of migrant workers residing in Korea is continuously increasing, which is exacerbating the workforce shortage in its society. Migrant workers experience health problems or stress due to rapid environmental changes, consequently impairing their quality of life (QoL). Accordingly, this literature review aimed to prepare basic data by identifying factors related to the health-related quality of life (HRQoL) of migrant workers in Korea. METHOD In total, the literature search used seven databases to find all documents corresponding to related subject words until June 7, 2022, including PubMed, Cumulative Index to Nursing and Allied Health Literature, Embase, Regional Information Sharing Systems, Korean Medical database, Science ON, and DataBase Periodical Information Academic. Furthermore, this study used the Cochrane Library and Google Scholar to manually search, to include comprehensive literature. Moreover, both English and Korean were used to search for the main terms. RESULTS In total, nine articles were selected. The World Health Organization Quality of Life Brief Version tool was used in six studies to measure HRQoL. Factors affecting the HRQoL of domestic migrant workers included general characteristics such as monthly income and residence period, physical and psychological health-related characteristics such as health promotion behaviour, medical service satisfaction, and depression, and social factors such as social support and cultural adaptation stress. Social support was an important variable affecting the QoL. Particularly, increased social support improved health-related QoL. In addition, higher medical service satisfaction and lower cultural adaptation stress increased HRQoL. CONCLUSIONS Social factors such as social support and cultural adaptation stress affect the HRQoL of migrant workers. Therefore, the social integration program should be expanded to ensure that migrant workers can adapt to the domestic culture at an early stage. In addition, people require active support to improve the QoL in Korea through activities such as self-help groups to help them cope with stressful situations and experience positive emotions. Moreover, it is necessary to provide information on domestic medical services as well as support for medical information for self-health management to improve the quality of medical services for migrant workers.

Abstract
BACKGROUND Enlarged facial pores are a common dermatological and cosmetic concern, which are difficult to treat because their pathogenesis is multifactorial. Many technological treatments have been developed to treat enlarged pores. Despite these efforts, enlarged pores remain problematic for many patients. OBJECTIVES Microcoring technology has recently been developed to treat pores and serve as a leading primary treatment option to address these concerns. METHODS Three patients underwent a single treatment of rotational fractional resection. The 0.5 mm diameter rotating scalpels were used to resect the skin pores in the cheek region. The resected site was evaluated 30 days after treatment, and the patients underwent scanning in bilateral 45° views at 60 cm from the face with the same brightness setting. RESULTS The three patients improved in terms of enlarged pores and had no severe skin-related adverse effects. Furthermore, the three patients showed satisfactory treatment outcomes after 30 days of follow-up. CONCLUSION Rotational fractional resection is a new concept that produces measurable permanent results for enlarged pore removal. These cosmetic procedures produced promising outcomes in a single treatment. However, the current clinical procedures trend demands minimally invasive treatment for enlarged pores.

Abstract
The prevalence of allergic diseases has been increasing globally prior to COVID-19. The pandemic resulted in changes in lifestyle and personal habits such as universal mask-wearing and social distancing. However, there is insufficient information on the impact of the COVID-19 pandemic on the prevalence of allergic conditions such as asthma, atopic dermatitis, and allergic rhinitis. We analyzed the incidence rate for self-reported and doctor-diagnosed cases of allergic diseases of asthma, atopic dermatitis, and allergic rhinitis. A total of 15,469 subjects were registered from a national cohort dataset of the National Health and Nutrition Examination Survey. Using multiple logistic regression analysis, we calculated the adjusted odds ratio (OR) for each disease in 2020 compared to 2019. Subgroup analyses were performed according to age and sex. There were no statistically significant differences between the incidence of doctor-diagnosed and current allergic diseases in 2019 and 2020 (asthma, p = 0.667 and p = 0.268; atopic dermatitis, p = 0.268 and p = 0.973; allergic rhinitis, p = 0.691 and p = 0.942, respectively), and subgroup analysis showed consistent results. Among the Korean population from 2019 to 2020, the incidence of the allergic diseases asthma, atopic dermatitis, and allergic rhinitis did not decrease as expected.

Abstract
Effective communication between nurses and physicians is necessary for prompt and accurate responses in clinical deterioration. This study aimed to examine nurses' perception and performance of communication with physicians in clinical deterioration situations in the ward. A descriptive research design with a survey of 250 ward nurses working in 2 tertiary hospitals was used. Regarding communication with the physician, nurses' perception was highest for timeliness, followed by accuracy, understanding, satisfaction, and openness, and their performance was highest for preparation, followed by situation, background, assessment, and recommendation. It is suggested that proactive activities for improving openness, accuracy, satisfaction, and mutual understanding between physicians and nurses are required for patient safety. Additionally, the performance for assessment and recommendations should be improved. Education programs for nurses and physicians should be developed and applied to clinical practice to promote understanding and trust in interprofessional communication.

Abstract
OBJECTIVE Chronic rhinosinusitis (CRS) is one of the most common chronic inflammatory diseases. The effect of chronic inflammation caused by CRS on the occurrence of various cancers has not been thoroughly evaluated. This study aimed to investigate the increased incidences of 10 types of cancers among CRS patients with/without nasal polyps (NP) using a national population-based database from the Korean Health Insurance Review and Assessment Service. STUDY DESIGN A case-control cohort study. METHODS We compared the prevalence of various comorbidities between CRS and control participants from a national cohort dataset of the Korean Health Insurance Review and Assessment Service. METHODS CRS participants (n = 6,919) and non-CRS (n = 27,676) participants were selected from among the 514,866 participants from 2002 to 2015. A stratified Cox proportional hazards model was utilized to assess the hazard ratio (HR) of CRS for 10 types of cancers. RESULTS A stratified Cox proportional hazard model demonstrated that the adjusted HR for hematologic malignancy was significantly higher in the CRS patients than in the controls regardless of the presence of NP (2.90 for total CRS; 2.15 for CRS with NP; 4.48 for CRS without NP). The HR for thyroid cancer was significantly higher in the CRS patients without NP but not in those with NP (1.50 for total CRS; 1.78 for CRS without NP). CONCLUSION This study showed that CRS participants had a significantly higher prevalence of hematologic malignancy and thyroid cancer. LEVEL OF EVIDENCE 4 Laryngoscope, 2022.

Abstract
BACKGROUND Chronic rhinosinusitis (CRS) is one of the most common chronic inflammatory diseases and is characterized by sinonasal inflammation that lasts longer than 12 weeks. Whether the effect of chronic inflammation caused by CRS on cardiovascular diseases (CVDs) is similar to its effect on other inflammatory disorders has not been thoroughly evaluated. We aimed to demonstrate whether CRS patients have a higher prevalence of CVDs, including stroke and ischemic heart disease (IHD). METHODOLOGY We compared the prevalence of various comorbidities between CRS and control participants through a case-control cohort study from 2002 to 2015 that included 514,866 participants. CRS (n=6,552) and control (n=26,208) participants who were over 40 years old were selected by matching age, sex, income, and area of residence at a 1:4 ratio. RESULTS A stratified Cox proportional hazards model was utilized to assess the hazard ratio (HR) of CRS for stroke and IHD. The HRs for stroke and IHD were significantly increased in CRS patients compared to controls after adjusting for obesity, alcohol consumption, smoking, systolic and diastolic blood pressure, fasting blood glucose, total cholesterol, hemoglobin, and Charlson Comorbidity Index (CCI) scores. The HR of stroke was significantly higher in the absence of nasal polyps than in the presence of nasal polyps. The HR of IHD was significantly increased in the CRS group regardless of the presence of nasal polyps. CONCLUSIONS This study showed that CRS participants had a significantly higher prevalence of stroke and IHD.

Abstract
Solitary fibrous tumor (SFT) is a spindle cell neoplasm that occurs commonly in the pleural space. One-third of SFTs arising from an extrathoracic organ are found in the head and neck region, and they arise rarely in the sinonasal tract. Most of these tumors are benign, but malignant tumors are identified in some cases. Here we report a rare sinonasal SFT arising from the frontal recess. A 32-year-old male patient with chief complaint of headache and left facial pain visited the outpatient clinic. He had suffered from paranasal pain and nasal obstruction for several months, and symptoms became more severe in the previous three months. The mass rapidly increased in size and was protruding from the left nostril when he visited the hospital. After computed tomography and magnetic resonance imaging scans, transnasal endoscopic resection of the tumor was performed, and gross total tumor removal was successfully achieved. We believe this case will be helpful for providing information regarding management of such uncommon huge sinonasal tumors originating from the frontal recess.

Abstract
Metastasis to the sinonasal cavity is rare. Late recurrence, such as metastasis developing 10 years or more after nephrectomy, is even more rare. We present a rare case of late metastatic renal cell carcinoma (RCC) in the maxillary sinus after nephrectomy and discuss reported sinonasal metastatic RCC cases. A 64-year-old man presented with left nasal obstruction for the previous one year. He had undergone right nephrectomy to treat RCC 12 years prior. Paranasal sinus computed tomography and magnetic resolution imaging revealed a 4.6-cm-diameter mass exhibiting delayed contrast enhancement that filled the left maxillary sinus and the nasal cavity. Histologically, clear cell RCC was diagnosed. We resected the maxillary sinus tumor to resolve the nasal obstruction for palliative symptom relief. There has been no evidence of recurrence to date, 3 years postoperatively. When a patient with a history of RCC presents with a hypervascular paranasal sinus mass, metastatic RCC should be considered, despite history of nephrectomy. It is important to make an appropriate treatment plan depending on extent of metastases and location of the metastatic tumor.

Abstract
This study aimed to evaluate the causal association of periodontal disease with acute myocardial infarction (AMI) and stroke, after controlling for various confounders among the Korean population. A retrospective cohort study using the National Health Insurance Service-National Health Screening Cohort (NHIS-HEALS) was performed during 2002 to 2015 (baseline: 2002 to 2005; follow-up: 2006 to 2015) in the Republic of Korea. A total of 298,128 participants with no history of AMI or stroke were followed up for 10 y. AMI and stroke were defined by a diagnosis using the International Classification of Diseases, 10th Revision (ICD-10) guideline. Periodontal condition was classified into 3 groups (healthy, moderate periodontal disease, severe periodontal disease [SPD]) using the combination of ICD codes, treatment codes in the NHIS, and recommendation of periodontal treatment by the dentists in HEALS. Various confounders, such as sociodemographic, behavioral, systemic, and oral health factors, including hypercholesterolemia, were considered. Multivariable Cox regression analysis was applied to estimate adjusted incidence rate ratio (adjusted hazard ratio [aHR]) based on person-year of periodontal condition for AMI, stroke, and nonfatal major adverse cardiovascular events (MACEs) encompassing AMI or stroke controlling for various confounders. Stratified analyses according to age group, sex, and toothbrushing frequency were also performed. After controlling for various confounders, participants with SPD compared with non-SPD participants had a higher incidence by 11% for AMI (aHR, 1.11; 95% confidence interval [CI], 1.02-1.20), by 3.5% for stroke (aHR, 1.035; 95% CI, 1.01-1.07), and by 4.1% for MACEs (aHR, 1.04; 95% CI, 1.01-1.07). The association of SPD with AMI and MACE was highly modified in females and adults aged 40 to 59 y. In the total Korean population, SPD increased total AMI events by 4.3%, total stroke events by 1.4%, and the total MACEs by 1.6%. Our data confirmed that SPD was causally associated with the new events of AMI and stroke.

Abstract
Objective Melanoma is major medical challenge and being able to monitor treatment response is critical. This study aimed to use molecular profiling of Asian patients with advanced melanoma who were receiving treatment with check-point inhibitors (CPIs) to identify novel biomarkers of tumor response. Methods Next-generation sequencing (NGS) was performed using tumor specimens collected from 178 Asian patients with metastatic melanoma receiving CPIs. The NGS data and clinical-pathological factors were analyzed for potential genetic biomarkers of tumor response to CPI treatment. Results The most common melanoma subtype was acral melanoma (40%), followed by cutaneous melanoma (32%), mucosal melanoma (26%), and others (2%). For calculation of treatment efficacy, 164 of the patients could be evaluated. The overall response rate was 45.7%, of which 41 cases exhibited complete responses (25.0%) and 34 showed partial responses (20.7%). There were no significant differences in tumor responses based on melanoma subtype (P = 0.295). Genetically, NRAS mutations, TP53 mutations, and NF2 deletions were significantly associated with resistance to CPIs (P < 0.05). In contrast, MYC and RPS6KB1 amplifications were associated with responsiveness to CPIs (P < 0.05). Median progression-free survival (PFS) for patients treated with CPIs was 5.9 months (95% CI, 3.8-8.05 months). Univariate analysis identified TP53 and BRAF mutations, NF2 deletions, and BIRC2 amplifications as poor prognostic factors for PFS (P < 0.05). Conclusions This study determined the integrated genomic profiles of Asian patients with metastatic melanoma receiving CPIs and identified candidate biomarkers that reflected treatment outcomes. The molecular characterization of Asian melanoma patients receiving check-point inhibitors (CPIs) using NGS has not been reported. NRAS and TP53 mutations and NF2 deletions were significantly associated with resistance to CPIs. MYC and RPS6KB1 amplifications were associated with responsiveness to CPIs. TP53 and BRAF mutations, NF2 deletions, and BIRC2 amplifications were poor prognostic factors for progression-free survival. This is the largest integrated genomic study to date that identifying novel biomarkers of CPIs in Asian melanoma patients.

Therapeutic Effects of Intranasal Tofacitinib on Chronic Rhinosinusitis with Nasal Polyps in Mice. Laryngoscope 2020; 131:E1400-E1407. [PMID: 32990335 DOI: 10.1002/lary.29129] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2020] [Revised: 08/24/2020] [Accepted: 08/27/2020] [Indexed: 12/15/2022]
Abstract
OBJECTIVES The Janus kinase/signal transducer and activator of transcription (JAK-STAT) pathway play a key role in immune modulation, especially in the polarization of T helper cells. JAK inhibitors reduce inflammation by inhibiting the phosphorylation of STAT. We investigated whether a JAK inhibitor, tofacitinib, can reduce inflammation in a mouse model of chronic rhinosinusitis with nasal polyps (CRSwNP). METHODS An eosinophilic CRSwNP model was induced using 4-week-old BALB/c mice. The therapeutic effects of topical tofacitinib were compared with the effects of triamcinolone acetonide (TAC). Polyp formation and eosinophilic infiltration were assessed by histology. Levels of phosphorylated STAT (pSTAT), eosinophil cationic protein, and eotaxin were measured by immunohistochemistry. Gene expression levels of GATA-3 was measured using quantitative PCR. The production of cytokines in sinonasal tissues, including interleukin IL-4, IL-5, IL-12, and interferon-γ, were measured using enzyme-linked immunosorbent assays (ELISA). RESULTS Topical tofacitinib administration significantly reduced the number of polyp-like lesions and the degree of eosinophilic infiltration, with an efficacy comparable with that of systemic TAC administration. Similarly, the levels of pSTAT6, eosinophil cationic protein, and eotaxin decreased with tofacitinib treatment. Tofacitinib decreased the gene expression level of GATA-3. Lastly, tofacitinib significantly decreased IL-4 and IL-5 production to a similar extent as that by systemic or topical TAC administration. Tofacitinib, but not TAC, significantly increased the production of interferon-γ. CONCLUSION Topical tofacitinib administration may be an effective treatment for eosinophilic CRSwNP by inhibiting phosphorylation of STATs. LEVEL OF EVIDENCE N/A. Laryngoscope, 131:E1400-E1407, 2021.

Abstract
The social-cognitive well-being model (SCWB; Lent, 2004) was designed to explain subjective well-being and other aspects of positive functioning within particular life domains. It has received a substantial amount of inquiry, especially in the context of academic and work satisfaction, in student and adult samples in the United States and other countries (Lent & Brown, 2006a, 2008). We present a meta-analysis synthesizing the empirical findings of 100 studies (154 samples) on the SCWB model that appeared between 2004 and 2017. The original model provided good overall fit to the data across all samples, and most of the predictors produced paths that were consistent with hypotheses. A culture-modified version of the model, which includes indicators of independent/individualistic and interdependent/collectivistic cultural orientations, also fit the data well, offering initial evidence for the incremental validity of these cultural variables in predicting well-being. Multigroup analyses showed that the model yielded acceptable fit in both academic and work domains. Within the academic domain, we also found adequate fit for the culture-modified model across gender, racial/ethnic groups, and U.S. and non-U.S. samples. At the same time, some group differences in parameter estimates were statistically and practically significant. Implications for the theory, its research base, and practical applications are discussed. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Abstract
Abstract
Background
Postnatal depression threatens the health of both mothers and babies. To improve maternal and child health in Seoul, South Korea, a nurse home visitation program for pregnant women and new mothers and babies has been implemented since 2013.
Methods
Cross-sectional data collected from 9,124 mothers while they were visiting a public health center for prenatal services or a nurse was visiting their home within 6 weeks after birth between 2014 and 2018 were analyzed. Mothers were asked whether they had experienced physical, emotional, or sexual abuse in their childhood. Postnatal depression and thoughts of self-harm were measured using the Edinburgh Postnatal Depression Scale (EPDS). Postnatal depression was defined as a total EPDS score of 13 or higher; thoughts of self-harm were defined as a response of “yes, quite often,” “sometimes,” or “hardly ever” to the corresponding item, excluding the response of “never".
Results
Overall, 3.2% of mothers had experienced child abuse; 8.1% experienced postnatal depression and 5.4% reported thoughts of self-harm. Postnatal depression was more common in mothers who had experienced child abuse than among those who had not (24.2% vs. 7.6%). A similar pattern was found for thoughts of self-harm (21.1% vs. 4.9%, respectively). When controlling for mothers’ age, economic status, history of receiving treatment for mental health problems, and other factors, having experienced child abuse was associated with a 2.73-fold increase in the odds of postnatal depression (odds ratio, 2.02-3.70) and a 3.58-fold increase in the odds of thoughts of self-harm (odds ratio, 2.58-4.96).
Conclusions
Mothers should be screened for having experienced child abuse when providing public health perinatal care to improve mothers’ mental health and parenting practices and to promote their children’s growth and development.
Key messages
Child abuse may have a lifelong negative effect on victims, and the effect extends to the next generation’s health and development. Public health policy and interventions to prevent child abuse are needed to tackle health inequality beginning in early childhood.

Abstract
Abstract
Background
Specific surface markers that enable monitoring of cell subsets would be valuable for establishing the conditions under which pluripotent stem cells (PSCs) differentiate into cardiac progenitor cells (CPCs) and cardiomyocytes (CMCs).
Methods and results
To verify whether a specific marker is expressed during heart development, we assessed its expression using the CLARITY technique. After immersion in a solution with a refractive index matching that of the CLARITY hybrid, the mouse embryo became transparent. After immunostaining the cleared embryo sample, Adgrl2 was exclusively observed in cardiac cells expressing α-SA at embryonic day E9.5 and E10.5. Our clarified 3D images and movies show that four chambers of the heart are fully developed at E10.5 but not at E9.5. At E9.5, Adgrl2 is observed at the ventricle and atrium, while Adgrl2 is present in all chambers of the heart at E10.5. Next, we performed LacZ (β-Gal) staining in heterozygous Adgrl2 KO embryos to evaluate Adgrl2 expression. As a result, LacZ staining showed that Adgrl2 was predominantly expressed in the heart during the embryonic developmental stage. Adgrl2 knockout in mice was embryonically lethal because of severe heart, but not vascular, defects. To examine the use of Adgrl2 as a bona fide CPC marker during heart development, we tracked Adgrl2 expression during early embryonic development. The heart of Adgrl2−/− embryos at E10.5 exhibited occlusion of the RV, and the expression levels of Gata4 and Nkx2.5 were not as high as those in wild-type and Adgrl2+/− embryos. Interestingly, the heart of Adgrl2−/− embryos, unlike those of wild-type and Adgrl2+/− embryos between E13.5 and E15.5 had a single ventricle revealing a ventricular septal defect. The specific expression pattern of Adgrl2 in PSC-derived cardiac lineage cells as well as in embryonic heart, adult mice, and human heart tissues.
Conclusion
We demonstrate that Adgrl2 plays a pivotal and functional role across all strata of the cardiomyogenic lineage, as early as the precursor stage of heart development. These findings shed light on heart development and regeneration.

Abstract
Abstract
Background
The clinical application of cell therapy to repair the damaged heart needs to understand the precise differentiation process of stem cells and the characteristics of cardiac progenitor cells.
Purpose
We examined the cardiac-specific markers that expressed on the cell surface and determined their functional significance during cardiac differentiation.
Methods and results
We screened cell-surface expressing proteins on cardiac progenitor cells at differentiation day 3 compared to undifferentiated pluripotent stem cells (PSCs). Among candidates, we identified lysophosphatidic acid receptor 4 (LPAR4) that is a G protein-coupled receptor. During in vitro differentiation of mouse PSCs toward cardiac cells, LPAR4 expression peaked for 3–5 days and then and declined immediately. Also in vivo, LPAR4 was specifically expressed in the early stage of heart development in embryos and disappeared completely in adults, suggesting that stimulatory signal of LPAR4 at an early stage should be shut off for further progression of differentiation. We next have identified the LPAR4 downstream signaling molecule, p38MAPK, by comparing PSCs and LPAR4 knockdown PSCs. In both mouse and human PSCs, ODP (LPAR4 specific agonist) followed by p38MAPK blocker (SB203580) treatment significantly increased cardiac differentiation efficiency. Furthermore, we investigated whether LPAR4 is the maker for adult cardiac progenitor cells. We found that LPAR4-positive cells were rarely present in normal adult mouse hearts, but LPAR4-positive cells were increased when the heart was damaged. LPAR4-positive cells from adult hearts differentiated into cardiomyocytes. After myocardial infarction (MI), the sequential stimulation and inhibition of LPAR4 with ODP and p38MAPK blocker resulted in the reduction of infarct size and improvement of left ventricular dysfunction.
Conclusion
We demonstrated that LPAR4 is a cardiac progenitor-specific marker and its functional significance during cardiac differentiation and regeneration. Our findings provide a new insight in cell-free cardiac repair by the modulation of progenitor-specific downstream signaling.

Abstract
BACKGROUND Surgical correction of severe caudal deviation of nasal septum using an endonasal approach is challenging for surgeons. Among cases of severe caudal septal deflection, fracture lines along the horizontal direction are occasionally encountered during the surgery. We devised a simple and efficient technique called "triangular excision and submucosal rejoining" to address this kind of deformity. METHODS A total of 9 patients with severe caudal septal deflection underwent "triangular excision and submucosal rejoining." After the removal of the deformed posteroinferior portion of the quadrangular cartilage, 2 incision lines were made on the remaining caudal septum, starting from a point at the most anterior portion of the fracture line and diverging posteriorly above and below the fracture line. After removing a triangular cartilaginous piece, the upper and lower remaining cartilage segments were approximated using a single or 2 simple interrupted sutures. Sutures exiting the mucosa were re-entered from the exit point so that all the sutures were buried underneath the mucosa while the mucosal flap was elevated only unilaterally. RESULTS This technique was effective in all cases. Septal batten grafts were applied in 3 patients, in whom the remaining quadrangular cartilage was weak and thin. One patient showed a mildly recurred septal deviation, but the nasal cavities remained patent with no symptoms. Serious complications such as dorsal saddling or tip ptosis did not occur in any cases. CONCLUSION "Triangular excision and submucosal rejoining" may be a safe and efficient septoplasty technique to correct a horizontally folded caudal septum.

Abstract
BACKGROUND A congenital divided nevus, also known as kissing nevus, is a type of congenital compound nevus that affects equal areas of the upper and lower eyelids. The edges of the nevus touch or "kiss" during closure of the lids, owing to its extension to the lid margins. Multiple treatment modalities, such as dermabrasion, cryotherapy, primary closure after excision, and skin grafts, have been proposed; however, complications such as recurrence, ectropion, skin color mismatch, and scar contractures are known to occur. This study aimed to introduce a staged excision using the 10,600-nm CO2 pulsed laser to remove a congenital divided nevus without noticeable complications. MATERIALS AND METHODS From August 2015 to December 2018, patients with congenital divided nevus underwent staged laser excision. Seven patients underwent staged mosaic pattern punch excision with a laser. Eight patients underwent concomitant excision, and one patient underwent skin grafting of the medial canthus. Patient satisfaction was assessed immediately and at 3 months after the procedure. RESULTS During the study period, 15 patients (10 women and 5 men), with a mean age of 26.0 years (range 13-73 years), underwent laser excision. Continuity of the eyelid margins was maintained in 13 patients. In one patient, the eyelashes grew inward and developed inflammation. No patient developed complications during the healing process, except for partial loss of cilia. Eleven patients were very satisfied, whereas three were satisfied with the results. One patient discontinued treatment after two laser sessions. CONCLUSION We performed multiple staged mosaic punching excisions of a congenital divided nevus with the CO2 laser in 15 cases. We observed consistent therapeutic results without definite recurrence, while maintaining the continuity of the eyelid and eyelash.

Abstract
BACKGROUND Septoplasty usefully treats patients with nasal obstructions caused by septal deviations. However, correction of a caudal septal deviation remains surgically challenging; no standard procedure is available, although various procedures have been introduced. In this work we propose a simple, safe, and time-saving technique for patients with caudal septal deviations. METHODS The medical records of 50 patients with caudal septal deviations who underwent septoplasty using a crossing-suture technique from October 2016 to October 2018 were retrospectively reviewed. Postoperative nasal obstruction status and patient satisfaction with their surgical outcomes were subjectively evaluated using the Nasal Obstruction Symptom Evaluation (NOSE) score and telephone interview, respectively. Pre- and postoperative endoscopic findings were evaluated and postoperative complications developing during follow-up were recorded. RESULTS The NOSE scores of all patients improved after septoplasty. The mean score fell from 13.46 to 3.97, and this change was significant (p < 0.0001). No complication related to use of the crossing suture was encountered. CONCLUSION The crossing-suture technique is a simple, safe, and useful surgical option for correction of caudal septal deviations.

Abstract
OBJECTIVES Poor wound healing as reflected by the development of synechia and osteitis after endoscopic sinus surgery may trigger disease recurrence. Animal models provide insights into the pathogenesis of poor wound healing and may aid in the development of new therapeutics. Here, we established a mouse model of nasal wound healing and confirmed its utility. STUDY DESIGN Animal study. METHODS Unilateral intranasal wounds were induced using a small interdental brush in 6-week-old C57BL/6 mice. Forty-five mice were divided into three groups (each n = 15): one control and two experimental groups (intranasal vs. intraperitoneal dexamethasone). Mice were sacrificed on days 2, 14, and 28 after injury (each n = 5). Serial changes in nasal wound histopathology were described, and intergroup differences were analyzed. RESULTS On day 2, mucosal detachment, hemorrhage, and exudate were observed. On day 14, synechiae featuring neo-osteogenesis (bone lacunae, osteoblasts, and multinucleated osteoclasts) between the septum and the maxilloturbinate were prominent, followed by wound maturation on day 28: fewer lacunae and smaller osteoblasts. Macrophages were evident only on day 2, and lymphocytes were predominant on day 28. The amount of exudate on day 2 and the synechial area on day 28 were significantly reduced in mice that received dexamethasone systemically compared with control mice, with similar trends in those treated intranasally. CONCLUSION Our mouse model of nasal wound healing was characterized by the development of bony synechia and neo-osteogenesis, not soft-tissue synechia. The model may be useful in the assessment of novel therapeutics to prevent those wounds. LEVEL OF EVIDENCE NA Laryngoscope, 129:E266-E271, 2019.

Abstract
BACKGROUND Medialization of the middle turbinate (MT) is an effective technique to prevent recurrent rhinosinusitis but could, in theory, reduce olfactory function by interfering the odorants to reach the olfactory mucosae. We performed a prospective randomized double-blind trial under the hypothesis that olfactory functions would be affected by the status of olfactory mucosae, not by MT medialization. METHODS In randomly selected sides, the unilateral MT was medialized in 80 patients undergoing bilateral endoscopic sinus surgery for chronic rhinosinusitis. The status of the bilateral olfactory cleft (OC) was photodocumented intraoperatively and categorized into patent (normal or mucosal swelling with discharge) and congested (hypertrophied mucosae or nasal polyps) groups. The butanol threshold test (BTT) was conducted in each nostril before and 6 months after the surgery. Correlation between the BTT scores and MT medialization or the OC status was assessed. No smell identification test was conducted side by side, which might limit clinical implications. RESULTS In total, 46 of 80 patients completed the trial. MT medialization was performed on the left and right side of the nose in 19 and 27 cases, respectively. The intraoperative OC status did not differ between the 2 sides. Perioperative changes in the BTT scores were similar between the medialized and intact MT sides, whereas the preoperative and postoperative BTT scores were higher in the patent OC group than in the congested OC group, regardless of side. CONCLUSION MT medialization does not impair olfactory function, and OC status is closely related to olfactory function.

Background A fragmented QRS complex (fQRS) is caused by conduction abnormalities of the ventricle secondary to myocardial ischemia and/or scar in patients with myocardial infarction. However, the implications of the fQRS in the development of coronary artery disease with myocardial ischemia in those without a scar remain unknown. Methods We studied electrocardiograms (ECGs) obtained from 150 patients (60.5 ± 8.5 years, 102 men) with myocardial ischemia, which was confirmed by performing both, a nuclear exercise stress test and coronary angiography. We also studied ECGs obtained from 601 patients (58.5 ± 10.0 years, 315 men) who showed a negative nuclear exercise stress test (control group). Patients in whom the nuclear exercise stress test showed a myocardial scar were excluded. Results An fQRS was more commonly observed in patients with myocardial ischemia (n = 48, 32.0%) than in the control group (n = 133, 22.1%) (P = 0.011). The sensitivity, specificity, positive, and negative predictive values of fQRS in diagnosing myocardial ischemia were 32.0, 77.9, 26.5, and 82.1%, respectively. The fQRS (odds ratio 1.580, 95% confidence interval 1.020‐2.446, P = 0.040) was an independent predictor of myocardial ischemia after adjusting for age, sex, current smoking habits, ST‐T changes on ECG, as well as histories of hypertension, diabetes, and dyslipidemia. Moreover, the fQRS showed an incremental prognostic value over conventional risk factors (χ2 = 5, P = 0.032) and over a combination of conventional factors and ST‐T changes (χ2 = 9, P = 0.014). Conclusions The fQRS is a moderately sensitive and independent predictor of myocardial ischemia.

Abstract
AIM Oblique lateral interbody fusion (OLIF) is a minimally invasive surgical method that can provide an access to the lumbar spine without direct dissection of psoas muscle and the need for intraoperative neuromonitoring (IOM) is questionable. The aim of this study was to examine and document the transient and persistent perioperative complications in patients who underwent OLIF for degenerative lumbar disease without IOM. MATERIAL AND METHODS A total of 129 consecutive patients who were diagnosed as degenerative spinal disease from L1 to S1 and underwent mini-open OLIF were identified and retrospectively reviewed. All patients were classified as two groups; non-IOM group and IOM group. According to the relation to surgical procedure, the complications were divided into two groups; "procedurerelated" and "procedure-unrelated". Based on the effect of duration, the complications were defined as "transient" where the symptom is relieved within 30 days postoperatively, and "persistent" where the symptom remains for more than 30 days postoperatively. RESULTS The study groups comprised 57 cases in the IOM group and 72 in the non-IOM group. The complication rate was 24.6% (transient; 17.6%, persistent; 7.0%) in the IOM group and 29.2% (transient; 25.0%, persistent; 4.2%) in the non-IOM group. The incidence of postoperative leg symptoms related to lumbar plexus and/or psoas muscle injury was 6 transient and 3 persistent in the IOM group (overall 15.3%), and 12 transient and 3 persistent in the non-IOM group (overall 20.9%). CONCLUSION Mini-open OLIF can be safely carried out without the aid of IOM.

Abstract
Contamination by organophosphate flame retardants (OPFRs) is an emerging concern in aquatic environments. Concentrations of 18 OPFRs were measured in water and sediments collected from the artificial Lake Shihwa. OPFR concentrations in sediments measured in this study were the highest reported worldwide, implying severe OPFR contamination. The highest concentrations of OPFRs were found in creeks taken near industrial complexes, and OPFR concentrations decreased with increasing distance from creeks to inshore or offshore lake waters. On-going OPFR contamination by wastewater treatment plant (WWTP) discharge was evidenced by the clear decrease in OPFRs in water samples collected moving away from WWTP outfall. TBEP and TEP were dominant in water samples, while TDCPP and TCPP were dominant in sediment samples. Differences in contamination profiles with sample matrices are likely due to hydrophobicity of individual OPFRs. Non-parametric multidimensional scaling ordination showed that OPFR contamination was affected by pollution inflow and proximity to industrial complexes.

Abstract
Background The olfactory bulb is anatomically exposed and thus can be directly damaged by external stimulation. This can occur as an occupational injury owing to contact with organic solvents or other causes. We present cases of eight patients who sustained occupation-related exposure to potentially toxic substances and later presented with signs and symptoms of anosmia. We examined the occupational and medical characteristics of the patients and evaluated their work-relatedness. Case presentation Case 1: A 50-year-old man performed high-frequency heat treatments for approximately 11 years. He experienced decreased senses for olfaction and taste during the later years culminating in the diagnosis of anosmia after 3 years (high work-relatedness). Case 2: A 54-year-old man whose work involved exposure to various organic solvents, such as spray painting and application of paint and thinners for approximately 4 years, was subsequently diagnosed with anosmia based on rhinorrhea, headache, and loss of olfaction (high work-relatedness). Case 3: A 44-year-old-man who performed spray painting for approximately 17 years developed anosmia (high work-relatedness). Case 4: A 44-year-old man was involved in ship engine cleaning once a month, for approximately 7 h per cleaning session; he was diagnosed with anosmia based on loss of olfaction (low work-relatedness). Case 5: A 41-year-old man worked in ship building block construction for approximately 13 years; anosmia diagnosis was based on loss of olfaction (low work-relatedness). Case 6: A 47-year-old woman performed product inspection and labeling at a plant manufacturing automobile parts; anosmia diagnosis was based on decreased olfaction and taste (low work-relatedness). Case 7: A 50-year-old woman performed epoxy coating in a plant manufacturing automobile parts; anosmia diagnosis was based on diminishing olfaction (low work-relatedness). Case 8: A 57-year-old woman performed cleaning of the area where mobile phone parts were manufactured; anosmia diagnosis was based on diminishing olfaction (low work-relatedness). Conclusion The study results confirmed work-relatedness when the subject was young, and the duration of exposure was long without any other cause of anosmia. Regarding compensation for occupational diseases, work-relatedness can be recognized as a relative concept.

Abstract
STUDY DESIGN Retrospective observatory analysis. OBJECTIVE The purpose of this study was to compare the incidence of perioperative complication, difference of cage location, and sagittal alignment between minimally invasive oblique lateral lumbar interbody fusion (MIS-OLIF) and MIS-direct lateral lumbar interbody fusion (DLIF) in the cases of single-level surgery at L4-L5. SUMMARY OF BACKGROUND DATA MIS-DLIF using tubular retractor has been used for the treatment of lumbar degenerative diseases; however, blunt transpsoas dissection poses a risk of injury to the lumbar plexus. As an alternative, MIS-OLIF uses a window between the prevertebral venous structures and psoas muscle. MATERIALS AND METHODS A total of 43 consecutive patients who underwent MIS-DLIF or MIS-OLIF for various L4/L5 level pathologies between November 2011 and April 2014 by a single surgeon were retrospectively reviewed. A complication classification based on the relation to surgical procedure and effect duration was used. Perioperative complications until 3-month postoperatively were reviewed for the patients. Radiologic results including the cage location and sagittal alignment were also assessed with plain radiography. RESULTS There were no significant statistical differences in perioperative parameters and early clinical outcome between 2 groups. Overall, there were 13 (59.1%) approach-related complications in the DLIF group and 3 (14.3%) in the OLIF group. In the DLIF group, 3 (45.6%) were classified as persistent, however, there was no persistent complication in the OLIF group. In the OLIF group, cage is located mostly in the middle 1/3 of vertebral body, significantly increasing posterior disk space height and foraminal height compared with the DLIF group. Global and segmental lumbar lordosis was greater in the DLIF group due to anterior cage position without statistical significance. CONCLUSIONS In our report of L4/L5 level diseases, the OLIF technique may decrease approach-related perioperative morbidities by eliminating the risk of unwanted muscle and nerve manipulations. Using orthogonal maneuver, cage could be safely placed more posteriorly, resulting in better disk and foraminal height restoration.

Abstract
BACKGROUND Benign paroxysmal positional vertigo (BPPV) is the most common cause of peripheral-type vertigo in the elderly. While some studies have investigated BPPV among the elderly, no study has focused on the isolated idiopathic BPPV (iBPPV) in the elderly. AIMS To investigate the clinical features and recurrence rate in elderly patients diagnosed with iBPPV. METHODS The authors prospectively reviewed the medical records of 627 patients diagnosed with BPPV, and a total of 370 patients fulfilled the inclusion criteria. The subjects were divided into two groups by age (experimental group ≥65 years and control group 17-64 years), and the gender, numbers of canalith reposition maneuver (CRM) for successful treatment, time elapsed from onset of symptoms to clinic visit, the affected semicircular canal, and the 1- and 5-year recurrence proportion were analyzed. RESULTS The gender, numbers of CRM for successful treatment, affected semicircular canal, and the 1- and 5-year recurrence proportion showed no statistically significant difference between two groups (p > 0.05). The only exception was the experimental group which took a longer duration from manifestation of symptoms to hospital visit than control group (student's t test, p = 0.021). DISCUSSION Several previous studies report that the elderly with iBPPV shows more protracted clinical course and much higher recurrence rate than younger adult. Unlike those reports, our study showed no significant differences about the clinical features and recurrence rate between age groups. CONCLUSION The elderly with iBPPV could be treated as effective as general population.

Abstract
Many patients visit the emergency department (ED) with abdominal pain. Sometimes, physicians are faced with diagnostic challenges, particularly for older patients. We recently had an elderly female patient who visited the ED several times with non-specific abdominal pain caused by an unusual hernia. One year before, an 81-year-old female visited our ED complaining of abdominal pain radiating to the right inguinal/femoral area. An incarcerated obturator hernia was found on an abdomino-pelvic computed tomography (CT) scan, and she underwent a laparoscopic hernioplasty. However, 1 year later, she revisited complaining of abdominal pain similar to the previous episode. Eventually, the diagnosis of recurrent obturator hernia was made, and a second operation was performed. An obturator hernia may be the cause of non-specific abdominal pain and small bowel obstruction in elderly emaciated females. Recognising the clinical signs and characteristics of this disease is necessary for a prompt diagnosis and treatment.

EphrinB1 promotes cancer cell migration and invasion through the interaction with RhoGDI1. Oncogene 2017; 37:861-872.

Abstract
Eph receptors and their corresponding ephrin ligands have been associated with regulating cell–cell adhesion and motility, and thus have a critical role in various biological processes including tissue morphogenesis and homeostasis, as well as pathogenesis of several diseases. Aberrant regulation of Eph/ephrin signaling pathways is implicated in tumor progression of various human cancers. Here, we show that a Rho family GTPase regulator, Rho guanine nucleotide dissociation inhibitor 1 (RhoGDI1), can interact with ephrinB1, and this interaction is enhanced upon binding the extracellular domain of the cognate EphB2 receptor. Deletion mutagenesis revealed that amino acids 327–334 of the ephrinB1 intracellular domain are critical for the interaction with RhoGDI1. Stimulation with an EphB2 extracellular domain-Fc fusion protein (EphB2-Fc) induces RhoA activation and enhances the motility as well as invasiveness of wild-type ephrinB1-expressing cells. These Eph-Fc-induced effects were markedly diminished in cells expressing the mutant ephrinB1 construct (Δ327–334) that is ineffective at interacting with RhoGDI1. Furthermore, ephrinB1 depletion by siRNA suppresses EphB2-Fc-induced RhoA activation, and reduces motility and invasiveness of the SW480 and Hs578T human cancer cell lines. Our study connects the interaction between RhoGDI1 and ephrinB1 to the promotion of cancer cell behavior associated with tumor progression. This interaction may represent a therapeutic target in cancers that express ephrinB1.

Abstract
PurposeTo identify prognostic factors in patients referred with endophthalmitis after cataract surgery, and to evaluate the efficacy of primary vitrectomy as an initial management.MethodsOver an eight-year study period, we retrospectively reviewed the medical records of 164 patients who were referred with endophthalmitis following cataract surgery. Treatment generally conformed to standard guidelines, although primary vitrectomy was performed in several eyes with a visual acuity of hand motion or better, depending on the patient's status. Using multivariate analysis, we analyzed outcomes to determine the effect on final visual outcome.ResultsA final visual acuity of ≥20/40 was achieved in 92/164 (56.1%) cases after treatment. Bacterial cultures showed bacterial growth in 89/164 cases (54.3%). Among the various baseline characteristics, old age (P=0.028), poor visual acuity at presentation (P=0.004), gram-negative bacterial infection (P=0.030), and short time between cataract surgery and signs of endophthalmitis (P=0.021) were associated with poor visual outcome. The visual outcome showed no significant difference, in terms of initial treatment feature, between the primary vitrectomy with intraocular antibiotics injection (IOAI) and IOAI-only groups. However, reintervention was significantly less frequent in the primary vitrectomy group than in the IOAI group (12.5 and 32.7%, respectively; P=0.002).ConclusionOld age, poor visual acuity at presentation, type of cultured organism (gram-negative bacteria), and early onset of endophthalmitis after cataract surgery were significantly related to poor visual outcome after endophthalmitis treatment. Primary vitrectomy may decrease the need for reintervention to control infection, although the treatment showed no benefits with regard to visual outcome.

Abstract
Study objective: To evaluate the feasibility and safety of vaginal vault drainage after complicated singleport access laparoscopic-assisted vaginal hysterectomy (SPA-LAVH). Design: Retrospective cohort study. Setting: Ulsan University Hospital (tertiary teaching hospital), South Korea. Patients: A total of 359 women underwent SPA-LAVH for the following conditions: benign uterine tumor, preinvasive uterine lesion, and microinvasive cervical cancer. Interventions: The participants included 124 women with vault drains and 235 women without drains. Measurements: Surgical outcomes, perioperative complications and morbidity, postoperative febrile morbidity. Results: There were no differences in background features between drain and no-drain groups. In surgical outcomes, mean uterine weight (364.2 ± 184.9 g vs. 263.7 ± 138.6 g; p < 0.001), operation time (87.4 ± 21.5 min vs. 73.0 ± 17.6 min; p < 0.001), blood loss (225.3 ± 122.2 mL vs. 150.4 ± 95.2 mL; p < 0.001), and hemoglobin decline (1.97 ± 0.96 g/dL vs. 1.42 ± 0.89 g/dL; p < 0.001) were significantly larger for the drain group compared with the no-drain group. However, with regard to postoperative morbidity and complications, there were no group differences in the transfusion rates (6.5% vs. 3.8%; p = 0.300), intraoperative complications (2.4% vs. 1.3%; p = 0.420), perioperative complications (2.4% vs. 0.9%; p = 0.345), and febrile morbidity ≥ 37.5°C (8.9% vs. 11.5%; p = 0.477), although the drain group was more prone to the development of pelvic fluid collection and febrile morbidity than the no-drain group. Conclusion: Vaginal vault drainage could be a safe alternative that allows for the management of postoperative morbidity and retains the advantages of minimally invasive surgery after complicated SPA-LAVH.

Abstract
BACKGROUND Acute invasive fungal rhinosinusitis (AIFR) is an aggressive opportunistic infection with a high mortality rate. Recently, non-invasive techniques have been introduced for diagnosis of invasive fungal disease. The purpose of this study is to evaluate the diagnostic significance of serum galactomannan measurement in patients with AIFR. METHODOLOGY We conducted a retrospective case-control study of 28 patients with AIFR and 36 fungus ball (FB) patients. We evaluated clinical, laboratory, and pathologic findings along with disease course. RESULTS In 28 patients with AIFR, there were 21 cases of invasive aspergillosis (IA) and 7 cases of invasive mucormycosis (IM). The control group was comprised of 36 patients with FB. The three-group analysis showed a statistically significant difference among the groups. At the cut-off value of 0.48, the sensitivity and specificity were 71.4% and 93.0%, respectively. Comparison of mean serum galactomannan levels in 5 non-survivors and 9 survivors at initial measurement showed no significant difference, but that became significantly different 1 week later. Statistical analysis showed that the levels of serum galactomannan decreased significantly according to the measurement-point in within survivor-group analysis. The difference in between survivor-groups analysis was also significant. CONCLUSION Serum galactomannan measurement seems useful for early diagnosis and discrimination of fungal species in patients with AIFR. In addition, clinical outcomes may be related to the levels and patterns of serum galactomannan, especially in IA. The appropriate measurement of galactomannan might be helpful in treating the patients at high risk for AIFR.

Abstract
Non-gestational choriocarcinoma (NGCO) is a rare primary ovarian cancer with poor prognosis. It is important to distinguish it from gestational ovarian choriocarcinoma (GCO), because there are different treatment options. However, it is difficult to distinguish the two types by routine histologic, ultrastructural, or immunohistochemical examination. The authors present NGCO in a 41-year-old woman, which was confirmed by DNA polymorphism analysis. All tested microsatellite markers had identical DNA profiles with the same allelic sizes between tumor and normal myometrium of the patient, indicating that both tissues originated from the same person. The results confirmed that the tumor was non-gestational in origin. Although the tumor was large, the authors performed hand- assisted laparoscopic surgical (HALS) staging. After three cycles of combination chemotherapy and surgery, the patient has not had any evidence of disease 48 months after treatment. This case demonstrates the usefulness of HALS staging and DNA polymorphism analysis in NGCO.

Abstract
BACKGROUND Although topical corticosteroids are considered a safe and effective drug for allergic rhinitis (AR), some AR patients do not show sufficient symptomatic improvement by use of topical corticosteroids. Topical cyclosporine is a safe and effective drug for patients with allergic conjunctivitis, particularly for those with steroid-resistant allergic conjunctivitis. We investigated the anti-inflammatory effects of intranasal cyclosporine for AR using a mouse model. METHODS After establishment of allergic inflammation in 5-week-old BALB/c mice, cyclosporine was administered intranasally 3 times per week for 2 weeks. To confirm its anti-inflammatory effects, triamcinolone acetonide (TAC) was utilized as a control drug. Histopathologic changes were evaluated using Sirius red and Giemsa staining for eosinophilic and mast cell infiltration, respectively. The levels of cytokines in sinonasal tissues, including tumor necrosis factor (TNF), interleukin (IL)-4, IL-5, and IL-13, were assessed based on a cytometric bead array. RESULTS The degree of eosinophilic infiltration was significantly decreased by instillation of cyclosporine, the potency being similar to TAC. However, the number of mast cells was not decreased by cyclosporine or TAC. The levels of TNF, IL-4, IL-5, and IL-13 were significantly decreased after treatment with cyclosporine. CONCLUSION The anti-inflammatory effects of topical cyclosporine for AR were equivalent to those of topical corticosteroids. Topical cyclosporine may be useful for the treatment of AR, although human studies are required.

Interleukin-4 enzyme-linked immunospot assay may be useful for diagnosing sensitization to house dust mite. Int Forum Allergy Rhinol 2016; 6:1007-1012. [PMID: 27122253 DOI: 10.1002/alr.21786] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2015] [Revised: 02/18/2016] [Accepted: 03/08/2016] [Indexed: 11/12/2022]
Abstract
BACKGROUND The skin prick test (SPT) is considered a standard test for identification of allergens, but it has some limitations in clinical practice. The multiple allergen simultaneous test (MAST), which measures allergen-specific immunoglobulin E in patients' serum, is a widely used alternative test, but is limited by its relatively low sensitivity and specificity. As a novel diagnostic test to identify allergens, we investigated the sensitivity and specificity of an interleukin-4 (IL-4) enzyme-linked immunospot (ELISpot) assay for Dermatophagoides farinae (Der f) and Dermatophagoides pteronyssinus (Der p). METHODS Based on the symptoms and SPT results, 43 house dust mite (HDM) allergic rhinitis (AR) patients and 41 control subjects were included. Peripheral blood was drawn from each subject for IL-4 ELISpot assay and MAST. The receiver operating characteristic (ROC) curve analysis was conducted to determine the cutoff values. Sensitivity, specificity, and positive and neg predictive values were compared between the 2 tests. RESULTS The sensitivity, specificity, and areas under the ROC curve (AUCs) of the IL-4 ELISpot assay were 88.4%, 97.6%, and 0.939 for Der f, and 95.3%, 97.5%, and 0.971 for Der p, respectively. However, the sensitivity, specificity, and AUC of MAST were 76.7%, 73.2%, and 0.777 for Der f, and 69.8%, 75.6%, and 0.788 for Der p, respectively. CONCLUSION The IL-4 ELISpot assay showed higher sensitivity, specificity, and AUC than MAST, which indicates its clinical feasibility for diagnosing allergy for HDM. A further study is needed to determine the accuracy of the IL-4 ELISpot assay for other common allergens.
