1.The mediating effects of test anxiety on the relationship between socially-prescribed perfectionism and academic burnout of female college students in a dental hygiene department.
Journal of Korean Academy of Oral Health 2015;39(4):295-302
OBJECTIVES: The purpose of this study was to uncover the mediating effects of test anxiety on the relationship between socially prescribed perfectionism and academic burnout in enrolled in a dental hygiene department. METHODS: This study administered a survey consisting of the Socially Prescribed Perfectionism Scale, the Revised Test Anxiety Scale, and the Maslach Burnout Inventory-Student Survey to 310 female college students in the dental hygiene department at G City. The data were analyzed with correlation analysis using SPSS 21.0 and AMOS 20.0. partial mediating effects of test anxiety between socially prescribed perfectionism and academic burnout. RESULTS: The results suggest that the higher the levels of socially prescribed perfectionism, the greater the increase in academic burnout. In addition, socially prescribed perfectionism increases test anxiety when academic burnout is high. The analysis of mediating effects in the indirect path of the model revealed that adaptive socially prescribed perfectionism had a negative effect on academic burnout by increasing test anxiety. These findings and their implications were discussed. CONCLUSIONS: In order to reduce socially imposed perfectionism, it is necessary to reduce growing academic burnout, and test the value and success criteria of this model. There remains however, the fact that there is a need to focus on career goals and criteria that need to be met in order to be successful. By lowering test anxiety, psychological stability is improved and in turn, a stable college life enables dental hygiene students to more freely access psychological support. Therefore, a proactive attitude toward education is vital in preventing test anxiety and socially prescribed perfectionism.

SPARC, secreted protein acidic and rich in cysteine, is a extracellular matrix-associated protein implicated in the modulation of cell adhesion, migration, cell cycle regulation, and angiogenesis. SPARC is expressed in fibrocytes and endothelial cells involved in tissue repair and invasive malignant tumors in the gastrointestinal tract, breast, lung, kidney, adrenal cortex, ovary, and brain. This study was aimed to characterize the different expression of SPARC in the thyroid follicular adenomas and follicular carcinomas. Immunohistochemical staining was performed in paraffin-embedded tissues of 25 follicular adenomas and 15 follicular carcinomas of the thyroid gland. Immunohistochemically, SPARC was not expressed in the 19 follicular adenoma and 2 follicular carcinoma but highly expressed in the 6 follicular adenoma and 13 follicular carcinoma. These findings suggest that SPARC is a potential diagnostic marker of follicular carcinoma and is helpful to distinguish follicular carcinoma from follicular adenoma without vascular or capsular invasion.

A retrospective study was designed to determine the diagnostic contribution of oblique view in 740 consecutive lumbar spine examinations done in adults. In 12 cases (1.62%) there was a change in the radiographic interpretation when the oblique views were used for diagnosis. Considering the significant gonadal radiation, additional cost, and limited diagnostic value, the authors feel that the oblique view should not be a routine part of the initial lumbar spine examination in adults.

OBJECTIVES: This research used queueing theory to analyze changes in outpatients' waiting times before and after the introduction of Electronic Medical Record (EMR) systems. METHODS: We focused on the exact drawing of two fundamental parameters for queueing analysis, arrival rate (λ) and service rate (µ), from digital data to apply queueing theory to the analysis of outpatients' waiting times. We used outpatients' reception times and consultation finish times to calculate the arrival and service rates, respectively. RESULTS: Using queueing theory, we could calculate waiting time excluding distorted values from the digital data and distortion factors, such as arrival before the hospital open time, which occurs frequently in the initial stage of a queueing system. We analyzed changes in outpatients' waiting times before and after the introduction of EMR using the methodology proposed in this paper, and found that the outpatients' waiting time decreases after the introduction of EMR. More specifically, the outpatients' waiting times in the target public hospitals have decreased by rates in the range between 44% and 78%. CONCLUSIONS: It is possible to analyze waiting times while minimizing input errors and limitations influencing consultation procedures if we use digital data and apply the queueing theory. Our results verify that the introduction of EMR contributes to the improvement of patient services by decreasing outpatients' waiting time, or by increasing efficiency. It is also expected that our methodology or its expansion could contribute to the improvement of hospital service by assisting the identification and resolution of bottlenecks in the outpatient consultation process.

OBJECTIVES: This study was conducted to evaluate the adoption behavior of a newly developed Electronic Medical Record (EMR)-based information system (IS) at three public hospitals in Korea with a focus on doctors and nurses. METHODS: User satisfaction scores from four performance layers were analyzed before and two times after the newly develop system was introduced to evaluate the adoption process of the IS with Rogers' diffusion theory. RESULTS: The 'intention to use' scores, the most important indicator for determining whether or not to adopt the IS in Rogers' confirmation stage for doctors, were very high in the third survey (4.21). In addition, the scores for 'reduced medication errors', which is the key indicator for evaluating the success of the IS, increased in the third survey for both doctors and nurses. The factors influencing 'intention to use' with a high odds ratio (>1.5) were the 'frequency of attendance of user training sessions', 'mandatory use of system', 'reduced medication errors', and 'reduced medical record documentation time' for both doctors and nurses. CONCLUSIONS: These findings show that the new EMR-based IS was well accepted by doctors. Both doctors and nurses also positively considered the effects of the new IS on their clinical environments.

BACKGROUND: The goal of successful resuscitation is not only to stop the process of ischemia as soon as possible but also to overcome the secondary injury process after resuscitation, which involves a complex interplay of mechanisms. Brain damage accompanying cardiac arrest and resuscitation is frequent and devastating. Cells die by one of two mechanisms: necrosis or delayed neuronal death. Delayed neuronal death may require protein synthesis. Neurons in the CA1 subfield of the hippocampus are selectively vulnerable to death after injury by ischemia and reperfusion. Death of these neurons occurs after an interval of 1 or 2 days. We assessed the effects of a protein synthesis inhibitor, cycloheximide(CHX), on hippocampal neuronal death of rats by using the ventricular fibrillation cardiac arrest(VFCA) model. METHODS: The effect of CHX(3mg/kg, s.c.) on hippocampal neuronal death was studied in two groups of 18 rats each, one group being subjected to a 2-min VFCA and the other to a 3-min VFCA. Each group was divided into three subgroups: control(group I,II) without subcutaneous injection of CHX, 'exp-12' of group I/II treated with CHX 12 hours after return of spontaneous circulation (ROSC), and 'exp-24' of group I/II treated with CHX 24 hours after ROSC. The coronal sections of the hippocampus levels were stained with hematoxylin-eosin after 72 hours of survival. The histologic damage score(HDS) was used to assign a score to the total number of damaged neurons counted in each of the hippocampal CA1 subfields. RESULTS: 1. There were not significan differences in heart rates, blood pressures, blood sugar, and blood gas in group I & II during the pre-arrest steady state or at 5 min and 30 min after ROSC. 2. In group I & II, the HDS, were significantly reduced in rats(I exp-12, 1.1+/-0.6; I exp-24, 1.3+/-0.5; II exp-12, 1.4+/-0.7; and II exp-24, 1.8+/-0.8) treated with CHX 12 hours or 24 hours after ROSC than control rats(I, 2.5+/-0.9, II, 2.9+/-0.8)(p<0.05). CONCLUSION: These results suggest that delayed hippocampal neuronal death from ischemic insult after ventricular fibrillation cardiac arrest followed by resuscitation can be prevented by a protein synthesis inhibitor, CHX. Further experimental studies of the action mechanism of protein synthesis inhibitors to delayed neuronal death and clinical applications are required.

Purpose:
To report a case of chronic conjunctivitis caused by Fusobacterium nucleatum misdiagnosed as adult inclusion conjunctivitis.Case summary: A 48-year-old female visited our clinic complaining of conjunctival injection and discharge in her right eye that had started 9 months earlier. Slit lamp examination showed conjunctival exudates with follicular hypertrophy on the upper and lower palpebral conjunctiva of the right eye. Adult inclusion conjunctivitis was suspected, and polymerase chain reaction tests for 12 sexually transmitted infections, serum Chlamydia trachomatis antibody test, sputum tests, and urine tests were performed. The serum trachomatis IgM was negative, but IgG was positive; there were no other specific findings. The patient was treated with oral doxycycline and topical antibiotics eyedrops for 1 week, but there was no improvement. Fusobacterium nucleatum was detected in a conjunctival swab culture. The oral antibiotic was changed to amoxicillin/clavulanic acid. After 1 week, the symptoms improved and the chronic conjunctivitis and follicles decreased; 4 weeks later, recovery was complete.
Conclusions
Chronic conjunctivitis caused by bacteria such as Fusobacterium nucleatum should be considered if adult inclusion conjunctivitis is suspected and does not respond to treatment.

PURPOSE: To investigate the clinical outcomes of combined vitrectomy and intrascleral fixation of a new posterior chamber intraocular lens (PC IOL) as a treatment for IOL dislocation. METHODS: We conducted a retrospective interventional study at our medical facility from January 2015 to January 2017. Posteriorly dislocated IOLs were removed with pars plana vitrectomy. Two intrascleral tunnels, 2.0 mm in length, were created 1.5 mm to the limbus at 6 and 12 o'clock positions. Both haptics of new foldable acrylic 3-piece IOLs were inserted into the tunnel until the IOL was secured in a central position. We analyzed the preexisting ocular condition, visual acuity (VA), and refractive error preoperatively and postoperatively, and recorded postoperative complications. RESULTS: Forty-nine patients (50 eyes) were enrolled in the study. The mean follow-up period was 12.8 ± 6.6 months. A best-corrected VA of 6/12 or better was achieved in 43 eyes (86%). The mean VA significantly improved from 0.32 logarithm of the minimum angle of resolution (logMAR) at baseline to 0.18 logMAR at last follow-up (p = 0.03). The refractive status after intrascleral fixation of the PC IOL revealed a mean hyperopic shift of +1.09 ± 1.28 diopters from the predicted spherical equivalent. Postoperative vitreous hemorrhages occurred in six cases and were cleared without visual compromise. Cystoid macular edema was well-controlled by topical nonsteroidal anti-inflammatory drugs (NSAID) medications in two cases. In two cases, IOL dislocation recurred and required re-operation. There were no serious adverse events of suture-related complications, retinal detachment, corneal compromise, or endophthalmitis in any of the patients. CONCLUSIONS: Our data revealed that use of combined vitrectomy and intrascleral fixation of PC IOLs is a safe and efficient technique to correct IOL dislocation. We observed good visual outcomes with only minor complications.

PURPOSE: To determine influences of intraoperative foveal traction during membrane peeling in idiopathic epiretinal membrane (ERM) surgery. METHODS: This retrospective observational study included 46 eyes of 46 patients with idiopathic ERM who underwent pars plana vitrectomy with ERM and internal limiting membrane peeling from February 2015 to September 2015. The presence of intraoperative foveal traction during membrane peeling was reviewed using video records. The main outcome measures were best-corrected visual acuity (BCVA), central foveal thickness (CFT), foveal contour, and photoreceptor inner segment/outer segment junction disruption using optical coherence tomography at baseline and at 1, 3, 6, and 12 months after surgery. RESULTS: Group 1 (ERM with intraoperative foveal traction) included 22 eyes, and group 2 (ERM without intraoperative foveal traction) included 24 eyes. Preoperatively, convex pattern ERM was observed more often in group 1. Group 1 had a significantly thicker CFT and a lower BCVA compared to group 2 at baseline and during the first 6 months, but the final postoperative BCVA and CFT were not significantly different between the groups at 12 months. Among 22 eyes, 12 eyes (54.5%) were restored to flat or concave ERM patterns at an average of 5.4 months after surgery in group 1, and 18 out of 24 eyes (75%) recovered at 2.4 months (p < 0.01) in group 2. CONCLUSIONS: Preoperative thick CFT and convex pattern ERM indicated a high possibility of intraoperative foveal traction in idiopathic ERM surgery. There were no differences in long-term BCVA and restoration of foveal configuration according to foveal traction during membrane peeling.

Central nervous system cryptococcosis is common in the AIDS patients with reported incidences ranging from 1.9% to 11.0%. Cryptococcosis may be the initial manifestation of HIV infection or occur simultaneously with other opportunistic infections. HIV-infected patients with central nervous system cryptococcosis complain of fever, headache, nausea and vomiting, and cognitive dysfunction. Meningeal signs and photophobia are less common than in HIV-negative patients. Focal neurologic signs and seizures are uncommon. Disseminated cryptococcosis is often concomitantly found at the time of central nervous system cryptococcosis. We report a case of 49 year-old Korean female with HIV infection who died of disseminated cryptococcosis with autopsy findings.
