Purpose: This study aimed to investigate whether the comprehensive nursing care service positively affected accidental falls and pressure injuries. Methods: This study was a retrospective study that analyzed the accidental falls and pressure injuries cases in an acute care hospital located in Seoul and compared the rates of accidental falls and pressure injuries before and after the comprehensive nursing care service was operated. Results: Comparing the accidental fall incidence rates per 100 person-months between a comprehensive nursing care ward and a general ward, it showed fewer accidental falls by 0.44 in comprehensive nursing care wards, but the result was not statistically significant. In the case of pressure ulcers, the incident rate per 100 person-month was 6.17 in general wards and 4.77 in comprehensive nursing care wards, which showed that the number of pressure ulcer patients was lower in comprehensive nursing care wards, however it was also not statistically significant. Conclusion It is not confirmed that the operation of the comprehensive nursing care service contributes to the reduction of accidental hospital falls or pressure injuries. Follow-up studies are recommended to determine the effectiveness of comprehensive nursing services in quality indicators.

Purpose: This study assessed the performance of transperineal ultrasonography (TPUS) in evaluating the treatment response in children with perianal Crohn’s disease (PACD) compared with pelvic magnetic resonance imaging (MRI). Methods: This retrospective study was approved by the Institutional Review Board of our institution, which waived the requirement for informed consent. Twenty-nine patients (19 boys and 10 girls; median age, 14 years [range, 8 to 18 years]) with 56 fistulas were examined. Each fistula’s thickness and abscess size were measured using both modalities, and treatment response was classified as positive or negative based on each modality. The concordance of the classifications was compared between TPUS and pelvic MRI. A receiver operating characteristic curve (ROC) was used to evaluate the performance of TPUS. Results: TPUS found 80.4% (45/56) of the fistulas. On MRI, 39 fistulas (70%) were classified as having positive treatment responses, and the remaining 17 as having no response. The agreement of the classifications between TPUS and MRI was moderate (κ=0.486; P<0.001; Spearman ρ=0.573; P<0.001). Based on the ROC analysis with the MRI findings as a reference to distinguish positive from negative treatment responses, TPUS exhibited sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of 63.3%, 93.3%, 95.0%, 56.0%, and 73.3%, respectively. Conclusion TPUS can be an appropriate adjuvant imaging modality for pelvic MRI to evaluate the treatment response of PACD in children when initial TPUS detects PACD with a location and imaging features comparable to those visualized on MRI.

Background: The aryl hydrocarbon receptor (AHR) and autophagy are both important to maintain skin homeostasis.However, they are also involved in skin disorders. So far, their roles in psoriasis pathogenesis are unknown. Objective: We studied the immunohistochemical and gene expression of AHR, CYP1A1, and microtubule-associated protein light chain 3 (LC3) in lesional skin of psoriasis patients to determine correlations among them. Methods: We included 24psoriasis patients and ten healthy volunteers. Skin biopsies were collected. AHR, CYP1A1, and LC3 protein expression was examined by immunohistochemistry, immunofluorescence, and western blotting. AHR, CYP1A1, LC3, ATG5, BECN1 and Nrf2 mRNA levels were measured by quantitative polymerase chain reaction. Results: AHR and CYP1A1 protein expression were higher in psoriasis lesional skin than in normal skin. LC3 protein expression was lower in psoriasis lesions than in normal controls. AHR and CYP1A1 protein expression in psoriasis lesions showed significant positive correlations with mean epidermal thickness and inflammatory cell density. Significant negative correlations were noted between LC3 protein expression in psoriasis lesions and the mean epidermal thickness or inflammatory cell density. A significant negative correlation was found between AHR and LC3 expression in psoriatic skin. AHR, CYP1A1 and Nrf2 mRNA expression were upregulated while LC3, ATG5, and BECN1 mRNA were down-regulated, in psoriatic lesional skin compared with normal controls. Conclusion AHR and autophagy could play a role in psoriasis pathogenesis by modifying epidermal hyperproliferation and inflammation. AHR and autophagy regulation are potential therapeutic targets in chronic inflammatory skin diseases.

ELISAs and rapid diagnostic tests (RDTs) are widely used for diagnosing dengue virus (DENV) infection. Using 138 single blood samples, we compared the ability to detect non-structural (NS)-1 antigen and anti-DENV IgM/IgG antibodies among (1) DENV Detect NS1 ELISA, DENV Detect IgM capture ELISA and DENV Detect IgG ELISA (InBios International, Inc.); (2) Anti-Dengue virus IgM Human ELISA and Anti-Dengue virus IgG Human ELISA (Abcam); (3) Dengue virus NS1 ELISA, Anti-Dengue virus ELISA (IgM) and Anti-Dengue virus ELISA (IgG) (Euroimmun); (4) Asan Easy Test Dengue NS1 Ag 100 and Asan Easy Test Dengue IgG/IgM (Asan Pharm); (5) SD BIOLINE Dengue Duo (Standard Diagnostics); and (6) Ichroma Dengue NS1 and Ichroma Dengue IgG/IgM (Boditech Med). For NS1 antigen detection, InBios and Euroimmun showed higher sensitivities (100%) than the RDTs (42.9–64.3%). All tests demonstrated variable sensitivities for IgM (38.1–90.5%) and IgG (65.7–100.0%). InBios and Boditech Med demonstrated higher sensitivity (95.6% and 88.2%, respectively) than the other tests for combined NS1 antigen and IgM antibody. Five NS1 antigen tests had good agreement (92.8–98.6%) without showing positivity for chikungunya. However, all IgG tests demonstrated potential false-positivity with variable ranges. Clinical laboratories should note performance variations across tests and potential cross-reactivity.

PURPOSE: To validate the Korean Version of the Jefferson Empathy Scale for Health professionals (K-JSE-HP) in a sample of Korean nurses. METHODS: Internal consistency reliability, construct and criterion validity were calculated using SPSS (22.0) and AMOS (22.0). Data were collected from 253 nurses (230 women, 23 men) working at one university hospital in Seoul, South Korea. RESULTS: The Korean version of JSE-HP showed reliable internal consistency with Cronbach's alpha for the total scale of .89, and .74~.84 for subscales. The model of three subscales for the K-JSE-HP was validated by confirmatory factor analysis (χ2=864.60, Q=6.55, p <.001, CFI=.94, NNFI=.92). Criterion validity compared to the Interpersonal Reaction Index (IRI) showed significant correlation. CONCLUSION: The findings of this study demonstrate that the Korean JSE-HP shows satisfactory construct and criterion validity and reliability. It is a useful tool to measure Korean nurses' empathy.

Trichomonas vaginalis, a causative agent of trichomoniasis, may trigger symptomatic or asymptomatic nongonococcal urethritis and chronic prostatitis in men. Despite the availability of highly sensitive diagnostic tests, such as nucleic acid amplification tests, including PCR, few prospective studies present data on male T. vaginalis infection in South Korea. In the present study, the prevalence of T. vaginalis and associated clinical conditions were evaluated in 201 male patients from a primary care urology clinic in South Korea. The prevalence of T. vaginalis infection in our cohort was 4% (8/201) by PCR. T. vaginalis infection was common in men older than 40 years (median age, 52 years). Among the 8 Trichomonas-positive patients, 87.5% (7/8) had prostatic diseases, such as prostatitis and benign prostatic hyperplasia, and 25.0% (2/8) and 12.5% (1/8) were coinfected with Chlamydia trachomatis and Mycoplasma genitalium, respectively. Our results suggest that T. vaginalis infection is not rare in men attending primary care urology clinics in South Korea, especially in those older than 40 years, in whom it may explain the presence of prostatic disease. The possibility of T. vaginalis infection should be routinely considered in older male patients with prostatic diseases in South Korea.

A 37-year-old female patient admitted due to dyspnea on exertion and peripheral edema. For one and a half years, the patient had been taking various drugs and supplements to reduce weight, including amphetamine-like drugs. The patient had no major cardiovascular risk factors except three pack-years of smoking. A chest computed tomography showed a 1.7 cm diameter, capsulated space-occupying lesion in the left ventricle (LV) and 2-dimensional echocardiography showed LV systolic dysfunction (Left ventricular ejection fraction [LVEF], 30%) with a mobile cystic mass (1.1x1.8 cm) that was attached to the LV apex, which was increased in size and number the next day, even with low dose low-molecular-weight heparin. With an increased dose of anticoagulation medication and heart failure management with diuretics and angiotensin receptor II blocker, LV dysfunction was recovered and the LV thrombus disappeared.

The pneumonia severity index (PSI) and CURB-65 are widely used tools for the prediction of community-acquired pneumonia (CAP). This study was conducted to evaluate validation of severity scoring system including the PSI and CURB-65 scores of Korean CAP patients. In the prospective CAP cohort (participated in by 14 hospitals in Korea from January 2009 to September 2011), 883 patients aged over 18 yr were studied. The 30-day mortalities of all patients were calculated with their PSI index classes and CURB scores. The overall mortality rate was 4.5% (40/883). The mortality rates per CURB-65 score were as follows: score 0, 2.3% (6/260); score 1, 4.0% (12/300); score 2, 6.0% (13/216); score 3, 5.7% (5/88); score 4, 23.5% (4/17); and score 5, 0% (0/2). Mortality rate with PSI risk class were as follows: I, 2.3% (4/174); II, 2.7% (5/182); III, 2.3% (5/213); IV, 4.5% (11/245); and V, 21.7% (15/69). The subgroup mortality rate of Korean CAP patients varies based on the severity scores and CURB-65 is more valid for the lower scores, and PSI, for the higher scores. Thus, these variations must be considered when using PSI and CURB-65 for CAP in Korean patients.

The consensus guideline development committee of Korean Society of Gynecologic Oncology was reconvened in March 2012. The committee consisted of 36 experts representing 12 university hospitals and professional organizations. The objective of this committee was to develop standardized guidelines for cervical cancer screening tests for Korean women and to distribute these guidelines to every clinician, eventually improving the quality of medical care. Since the establishment of the consensus guideline development committee, evidence-based guidelines have either been developed de novo considering specific Korean situations or by adaptation of preexisting consensus guidelines from other countries. Recommendations for cervical cancer screening tests, management of atypical squamous and glandular cells, and management of low-grade and high-grade squamous intraepithelial lesions were developed. Additionally, recommendations for human papillomavirus DNA testing and recommendations for adolescent and pregnant women with abnormal cervical screening test results were also included.

Procedural sedation and analgesia (below PSA), which is used for induction of appropriate sedation and elimination of pain during many procedures, is particularly essential for children. Many other countries have pediatric PSA guidelines. PSA guidelines are also needed in Korea. We have developed pediatric PSA guidelines for Korea by reference review of pediatric PSA for standard and safe PSA practice in Korea. Pharmacologic and non-pharmacologic methods could be used for performance of ideal pediatric PSA. Pre sedation phase included assessment of patients, with accompanying personnel who have adequate knowledge and experience, and informed consent. For sedation phase, the route of medication should be determined, along with monitoring of patients and evaluation of the depth of sedation. This phase also included writing all of the PSA process, adverse events, and intervention. Considering the pain of the procedures, the time of procedures, necessity for immobilization, and characteristics of PSA medication, we decided on the PSA method. Procedures were categorized into three types according to the level of pain, anxiety, and immobilization. The first type was radiologic imaging, which requires immobilization. The second type of procedure involves a high level of anxiety and a low level of pain, such as simple suturing and lumbar puncture. The third type of procedure involves a high level of anxiety and a high level of pain, such as reduction of fracture and dislocation. After performance of the procedure, patients must be observed and monitored at a location where oxygen and airway management can be applied until they reach full recovery. Discharge information should be provided to competent parents. The main characteristics of Korean guidelines for pediatric PSA were as follows: 1. We emphasized assessment and monitoring of patients during and after PSA. 2. We suggested selection of medication by categorization of procedures according to the level of pain and anxiety. 3. We suggest that PSA be performed by two healthcare personnel; one should have adequate knowledge and experience in performance of PSA. More equipment, locations, and specialized personnel are needed for conduct of safe pediatric PSA practice in Korea.
