Exercise rehabilitation for recurrent extraocular muscle movement limitation after pediatric blowout fracture surgery: a case report

White-eyed blowout fractures with extraocular muscle (EOM) entrapment necessitate emergency surgical intervention. However, even after surgery, diplopia or EOM motion limitations may persist due to the incomplete reduction of soft tissue herniation caused by inadequate dissection or unresolved muscle strangulation. In this report, we present a case of postoperative EOM movement limitation in a 5-year-old girl who experienced recurrent restriction in the upward gaze of her right eye 14 days after surgery. Instead of revision surgery, the patient was treated with targeted EOM exercises focusing on the inferior rectus muscle and inferior oblique muscle. The patient was instructed to slowly move her pupils from the central point to the upper and outer sides, then in a straight line from the central point to the lower and inner sides before returning to the center point. On the 28th postoperative day, 2 weeks after initiating the exercises, the patient’s EOM motion fully recovered. This case highlights the effectiveness of EOM exercises as a non-surgical treatment approach for improving recurrent EOM movement limitations in the absence of soft tissue herniation following surgical management of blowout fractures in children.

Full mouth rehabilitation with fixed prostheses by increased vertical occlusal dimension using 3D printed splint in a patient with excessive tooth wear / 대한치과보철학회지

Severe wear of the anterior teeth facilitates the loss of anterior guidance, which protects the posterior teeth from wear during excursive movement. Additionally, when treating patients with collapsed occlusion due to multiple tooth loss and tooth wear, it is important to determine the presence of vertical dimension loss through accurate clinical and radiographic examinations and diagnostic wax-up. The patient of this case is a 44-year-old female patient who complained of overall tooth wear and loss of posterior teeth due to bruxism and clenching habits, visited the hospital with the address of restoring masticatory function and improving aesthetic appearance through prosthetic treatment. Through model analysis and diagnostic wax-up, an increase in vertical dimension was determined, and full mouth restoration with fixed prostheses was planned. The degree of adaptation to the vertical dimension was confirmed step by step using an occlusal splint designed with CAD (Computer aided design) software and 3-D (3-Dimensional) printed, and then restored with provisional restoration and after a 4-month adaptation period, the entire dentition was restored with metal ceramic crowns and implants. Through this procedure, satisfactory treatment results were obtained in terms of function and aesthetics.

Induction of liver transplant immune tolerance in an outbred rat strain model using tacrolimus / 한국실험동물학회지

Background@#Orthotopic liver transplantation is the only option for patients with end-stage liver disease and hepatocellular carcinoma. Post-transplant immunosuppressive therapy is important to prevent graft failure. We investigated the effectiveness of tacrolimus (FK506) and their mechanisms for liver transplant immune tolerance in an outbred rat LT model. @*Results@#To investigate the therapeutic effect of the FK506 on outbred rat LT model, FK506 and postoperative therapy were administered subcutaneously once or twice daily to transplanted rats. Histopathological and immunohistochemical analyses were conducted for all groups. The regulation of inflammatory cytokine signaling in the spleen was analyzed by flow cytometry. FK506 attenuated allograft rejection and increased survival in rat orthotopic liver transplantation models. The FK506-treated group had reduced serum levels of alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase. Furthermore, FK506 decreased the expression of inflammatory cytokines and the activation of pathogenic Th1 and Th17 cells in the liver. @*Conclusions@#Taken together, we revealed that FK506 ameliorated strong allograft rejection in outbred liver transplantation model by anti-inflammatory effect and inhibitory peroperty of pathogenic T cells.

Pathway Analysis on the Effects of Nursing Informatics Competency, Nursing Care Left Undone, and Nurse Reported Quality of Care on Nursing Productivity among Clinical Nurses

Purpose@#Nursing informatics competency is used to manage and improve the delivery of safe, high-quality, and efficient healthcare services in accordance with best practices and professional and regulatory standards. This study examined the relationship between nursing informatics competency (NIC), nursing care left undone, and nurse reported quality of care (NQoC) and nursing productivity. A path model for their effects on nursing productivity among clinical nurses was also established. @*Methods@#Data were collected using structured questionnaires answered by 192 nurses working in a tertiary hospital located in J city, Korea, and analyzed using SPSS/WIN 23.0 and AMOS 21.0 program. @*Results@#The fit indices of the alternative path model satisfied recommended levels χ2 = .11 (p= .741), normed χ2 (χ2/df) = .11, SRMR = .01, RMSEA = .00, GFI = 1.00, NFI = 1.00, AIC = 18.11. Among the variables, NIC (β = .44, p < .001), NQoC (β = .35, p < .001) had a direct effect on nursing productivity. Due to the mediating effect of NQoC on the relationship between NIC and nursing productivity, the effect size was .14 (95% CI .08~.24). Meanwhile, nursing care left undone through NQoC in the relationship between NIC and nursing productivity, has a significant mediation effect (estimate .01, 95% CI .00~.03). The explanatory power of variables was 44.0%. @*Conclusion@#Education and training for enhancing NIC should be provided to improve nursing productivity, quality of care and to reduce missed nursing care. Furthermore, monitoring the quality of nursing care and using it as a productivity index is essential.

Associations between the Munk Score and Tear Film Scan Revealed byCorneal Topography after Dacryocystorhinostomy

Purpose@#We evaluated changes in the tear film parameters of the corneal surface, and their correlations with Munk scores,based on corneal topographic scans of patients with nasolacrimal duct obstructions who underwent dacryocystorhinostomy(DCR). We explored whether tear parameters can serve as useful indicators of functional surgical success. @*Methods@#We assessed 72 eyes of 45 patients diagnosed with nasolacrimal duct obstruction who underwent DCR. Tear film parameterswere measured via corneal topography (Keratograph® 5M) once before, and three times after surgery, and includedtear meniscus height (TMH), and the initial and average keratographic tear break-up time (NIKBUT-first and NIKBUT-average,respectively; measured noninvasively). @*Results@#The three postoperative TMH values were 0.31 ± 0.20, 0.30 ± 0.22, and 0.29 ± 0.15 mm, all of which were significantlylower than the preoperative value of 0.48 ± 0.29 mm (all, p 0.999).Changes in the Munk score after surgery correlated significantly with changes in the TMH (r = 0.46, p < 0.001). When functionalsuccess was defined as a Munk score ≤ 1, the area under the curve (AUC) value corresponding to the ability of TMH to definefunctional success of 0.995, was statistically significant (cut-off of 0.31 mm; p < 0.001). @*Conclusions@#The TMH DCR correlated significantly with the Munk score, which is a quantitative measure of clinical symptomseverity. The ability of TMH to define functional surgical success was excellent.

Validity and Reliability of the Clinical Teaching Behavior Inventory (CTBI) for Nurse Preceptors in Korea

PURPOSE: The aim of this study was to evaluate the validity and reliability of the Korean version of the Clinical Teaching Behavior Inventory (CTBI). METHODS: The English CTBI-23 was translated into Korean with forward and backward translation. Survey data were collected from 280 nurses' preceptors at five acute-care hospitals in Korea. Content validity, construct validity, and criterion-related validity were evaluated. Cronbach's α was used to assess reliability. SPSS 24.0 and AMOS 22.0 software was used for data analysis. RESULTS: The CTBI Korean version consists of 22 items in six domains, including being committed to teaching, building a learning atmosphere, using appropriate teaching strategies, guiding inter-professional communication, providing feedback and evaluation, and showing concern and support. One of the items in the CTBI was excluded with a standardized factor loading of less than .05. The confirmatory factor analysis supported good fit and reliable scores for the Korean version of the CTBI model. A six-factor structure was validated (χ²=366.30, p<.001, CMIN/df=2.0, RMSEA=.06, RMR=.03, SRMR=.05, GFI=.90, IFI=.94, TLI=.92, CFI=.94). The criterion validity of the core competency evaluation tool for preceptors was .77 (p<.001). The Cronbach's α for the overall scale was .93, and the six subscales ranged from .72 to .85. CONCLUSION: The Korean version CTBI-22 is a valid and reliable instrument for identifying the clinical teaching behaviors of preceptors in Korea. The CTBI-22 also could be used as a guide for the effective teaching behavior of preceptors, which can help new nurses adapt to the practicalities of nursing.

Late Postoperative Opacification of Multifocal Intraocular Lens after Vitrectomy in a Diabetic Patient

PURPOSE@#We report a case of late opacity of an AT LISA intraocular lens after vitrectomy in a diabetic patient.CASE SUMMARY: A 61-year-old man presented with blurring in the left eye. He had undergone bilateral phacoemulsification and intraocular lens implantation 6 years ago, and vitrectomy with SF₆ gas tamponade in the left eye due to rhegmatogenous retinal detachment 3 years ago. The patient was diagnosed with pre-existing diabetes, hypertension, and coronary heart disease. Examination of the left eye showed round and centrally located whitish fine granular deposits on the surface of the intraocular lens, and zonular rupture from the 3 to 6 o'clock position. The intraocular lens in the right eye was clear. The corrected vision was 0.9 in the right eye and 0.5 in the left eye. The intraocular lens was explanted from the left eye together with the capsular bag, and was examined under light microscopy, histochemical analysis, and with scanning electron microscopy equipped with an energy dispersive X-ray spectroscopy detector with light element capabilities.@*CONCLUSIONS@#This study was the first to report late postoperative opacity in the multifocal intraocular lens, AT LISA 809M. The possibility of intraocular lens opacity in patients with underlying disease or in those undergoing vitrectomy should be explained prior to corrective procedures.

Secular change in waist circumference and waist-height ratio and optimal cutoff of waist-height ratio for abdominal obesity among Korean children and adolescents over 10 years / 소아과

PURPOSE: This study aimed to evaluate the time trends of waist circumference (WC) and waist-height ratio (WHR), and to present WC and WHR distributions with optimal WHR cutoff for abdominal obesity in Korean children and adolescents. METHODS: We performed a retrospective cross-sectional analysis of data from 13,257 children and adolescents (6,987 boys and 6,270 girls) aged 6–18 years who were included in the third to sixth Korea National Health and Nutrition Examination Survey (KNHANES, 2005–2015). Linear regression analyses were used to identify secular changes in WC and WHR by age, sex, and KNHANES waves. A receiver operating characteristic curve analysis was used to determine the optimal WHR cutoff values for abdominal obesity and cardiometabolic risk factors. RESULTS: The mean WC and WHR distributions from 2005 to 2015 showed no significant secular changes between the KNHANES 4 waves (P for trend ≥0.05 in all ages and both sexes). The mean WCs in the present study were lower than those in the 2007 Korean National Growth Charts. The mean WHR at ages <13 years was statistically higher in the boys than in the girls, but did not significantly differ between the sexes among those aged 13 to 18 years. The optimal WHR cutoff for abdominal obesity was 0.48 (area under the curve, 0.985; 95% confidence interval, 0.985–0.985) in the 13- to 18-year-old adolescents. CONCLUSION: WC and WHR showed no secular changes over 10 years. The optimal WHR cutoff for abdominal obesity of 0.48 is useful for diagnosing and managing obesity and thus preventing obesity-related cardiometabolic complications in 13- to 18-year-old Korean adolescents.

Comparing adult height gain and menarcheal age between girls with central precocious puberty treated with gonadotropin-releasing hormone agonist alone and those treated with combined growth hormone therapy

PURPOSE: This study aimed to investigate the outcomes of gonadotropin-releasing hormone agonist (GnRHa) therapy with or without growth hormone (GH) therapy for girls with idiopathic central precocious puberty (CPP). METHODS: The medical records of 166 girls diagnosed with CPP from 2002 to 2017 were retrospectively reviewed. All included patients were treated with GnRHa for ≥36 months. Changes in height standard deviation score (SDS) for bone age, chronological age (CA), and predicted adult height (PAH) were assessed for the first three years of treatment. The final height gain SDS was calculated as the difference between the initial PAH SDS and adult height (AH) SDS; these were then compared between the GnRHa group (group A, n=135) and the combined GnRHa/GH group (group B, n=31).

Etiology and treatment of central precocious puberty

The timing of pubertal onset is occurring at younger ages. This phenomenon is associated with many environmental factors such as sufficient nutrition, stress, many kinds of endocrine-disrupting chemicals, and genetic background. The loss of transcriptional repression induces kisspeptin release, resulting in pulsatile gonadotropin-releasing hormone secretion, which trigger pubertal onset. According to many reports, gonadotropin-releasing hormone agonists therapy for patients with rapidly progressive central precocious puberty is effective for improving final adult height. However, those results were obtained from the treatment of relatively young patients at earlier stages of puberty. A large cohort study investigating the environmental causes of precocious puberty as well as genetic factors is needed.

Factors Influencing Nursing Students' Choices of a Place of Employment

BACKGROUND: Despite increasing the number of newly licensed nurses across Korea, shortages caused by geographical imbalances remains a significant concern. Therefore, understanding nursing students' attitudes to working and living, factors influencing where they first choose to work after graduation is useful in formulating appropriate interventions to retain nurses in regional areas. METHODS: A total of 329 senior nursing students from areas outside Metropolitan Seoul completed self-report questionnaires. Data were analyzed using t-test, chi-square test and multiple logistic regression analysis. RESULTS: Of the respondents, 57.8% reported that they planned to work in the region in which their school was located. The three factors ranked as having the greatest influence on their decision to work in non-metropolitan regions were: the cost of living, housing costs, and the proximity to family. Enjoyable aspects of rural life contributed positively to students' intentions to work in non-metropolitan regions, whereas isolation and socialization problems negatively affected their intentions to work in such areas. CONCLUSIONS: Greater consideration should be given to improving working conditions and housing environments in non-metropolitan regions.

Development of a Team Effectiveness Scale for Nursing Units / 간호행정학회지

PURPOSE: The purpose of this study was to develop a Team Effectiveness Scale for Nursing Units (TES-NU) and verify validity and reliability of the developed scale. METHODS: A preliminary 69 item version of the TES-NU was developed through in-depth interviews. The draft scale was developed using 65 items selected following content validity evaluation. Finally, thirty items with response options on a 5-point Likert scale were selected based on internal consistency reliability and construct validity. Subsequently, convergent validity of the TES-NU was verified. RESULTS: Six factors, namely, leadership of the head nurse, cohesion, job satisfaction, competency of nurses, productivity, and coordination were identified. These factors explained 64.6% of the total variance. The TES-NU's Cronbach's α for the total scale was .94. The correlation coefficient between the scores of the TES-NU and Ahn's Team Effectiveness scale was .59. CONCLUSION: Results show that the TES-NU developed in this study has good reliability and validity. Therefore, this TES-NU is recommended as a useful tool for managing team effectiveness for nursing units.

Assessment of the Influence of Application Time of Lidocaine Patch on Pain Intensity after Venipuncture / 기본간호학회지

PURPOSE: This study was done to assess the influence of application time of Lidocaine patch on pain intensity following venipuncture in hospital. METHODS: The participants were 31 adult patients admitted to J hospital in G city. Patients' anxiety, blood pressure and pulse were measured when no patch was applied and when a patch was applied. To evaluate the pain intensity and physiological index caused by venipuncture, blood pressure, pulse and pain intensity were checked for patients in the no patch group, and for a 5 minutes of application and 30 minutes application patch. Pain was evaluated using a visual analogue scale, anxiety using the Profile of Mood states developed McNair et al. and modified by Lee. Data were analyzed using one-way repeated measures ANOVA with the SPSS 21.0 program. RESULTS: Anxiety and pain were significantly reduced when a lidocaine patch was applied following venipuncture. There was no significant difference in pain intensity whether the lidocaine patch application is for 30 minutes or application for 5 minutes. CONCLUSION: Results of this study show that application of lidocaine patch can be used as a nursing intervention for pain reduction by showing that there is no need to wait a long time for pain to be reduced.

Two Small Intravenous Catheters for High-Rate Contrast Medium Injection for Computed Tomography in Patients Lacking Superficial Veins to Accommodate a Large Catheter

OBJECTIVE: To prospectively investigate the feasibility of using 2 small intravenous catheters for high-rate computed tomography (CT) contrast injection in patients lacking superficial veins capable of accommodating ≤ 20-gauge catheters. MATERIALS AND METHODS: Sixty-eight consecutive eligible adults referred for dynamic liver CT were enrolled; 58 had previously undergone liver CT, including 8 that experienced extravasation. Two 22- or 24-gauge catheters were placed in all patients after 2–5 venipunctures, and 2 mL/kg of contrast agent (370 mg I/mL) was split-administered through both catheters to achieve total flow rate of 4 mL/s. Patients' experience and examination success rate, defined as uneventful scans completed at 4 mL/s or at < 4 mL/s achieving standard image quality in all phases, were analyzed. Quantitative hepatic signal-to-noise and hepatic vascular contrast-to-noise ratios (CNRs) were compared with 30 control examinations scanned at 4 mL/s using an 18-gauge catheter. RESULTS: One case each of extravasation and severe injection pain caused the examination to be aborted. Success rate was 88.2% (60/68; 54 patients scanned at 4 mL/s, 6 at 3.5–3.9 mL/s). Fifty-five of 58 patients (94.8%) that had past CT regarded the venipuncture as more tolerable than (n = 36) or similar to (n = 19) past experiences; 45 of 58 patients (77.6%) found contrast injection less painful than (n = 35) or similar to (n = 10) past experiences. When compared with control examinations, signal-to-noise ratio was similar in all phases (p ≥ 0.502), but the hepatic arterial CNR in arterial phase was slightly inferior (p ≤ 0.047). CONCLUSION: Using 2 small intravenous catheters can effectively achieve high-rate CT contrast injection in patients lacking adequate superficial veins.
