Korean Journal of Ophthalmology 2019;33(1):1-7
PURPOSE: To understand the ophthalmic clinical features and outcomes of facial nerve palsy patients who were referred to an ophthalmic clinic for various conditions like Bell's palsy, trauma, and brain tumor. METHODS: A retrospective study was conducted of 34 eyes from 31 facial nerve palsy patients who visited a clinic between August 2007 and July 2017. The clinical signs, management, and prognosis were analyzed. RESULTS: The average disease period was 51.1 ± 20.6 months, and the average follow-up duration was 24.0 ± 37.5 months. The causes of facial palsy were as follows: Bell's palsy, 13 cases; trauma, six cases; brain tumor, five cases; and cerebrovascular disease, four cases. The clinical signs were as follows: lagophthalmos, 24 eyes; corneal epithelial defect, 20 eyes; conjunctival injection, 19 eyes; ptosis, 15 eyes; and tearing, 12 eyes. Paralytic strabismus was found in seven eyes of patients with another cranial nerve palsy (including the third, fifth, or sixth cranial nerve). Conservative treatments (like ophthalmic ointment or eyelid taping) were conducted along with invasive procedures (like levator resection, tarsorrhaphy, or botulinum neurotoxin type A injection) in 17 eyes (50.0%). Over 60% of the patients with symptomatic improvement were treated using invasive treatment. At the time of last following, signs had improved in 70.8% of patients with lagophthalmos, 90% with corneal epithelium defect, 58.3% with tearing, and 72.7% with ptosis. The rate of improvement for all signs was high in patients suffering from facial nerve palsy without combined cranial nerve palsy. CONCLUSIONS: The ophthalmic clinical features of facial nerve palsy were mainly corneal lesion and eyelid malposition, and their clinical course improved after invasive procedures. When palsy of the third, fifth, or sixty cranial nerve was involved, the prognosis and ophthalmic signs were worse than in cases of simple facial palsy. Understanding these differences will help the ophthalmologist take care of patients with facial nerve palsy.

3.Mediating Effects of Self Efficacy and Self-Control in Nursing Students' Smartphone Addiction
Journal of Korean Academy of Psychiatric and Mental Health Nursing 2018;27(3):293-302
PURPOSE: The purposes of this study were to investigate the factor of smartphone addiction based on Agnew's general strain theory and examine the mediating effects of self efficacy and self-control in the identified model of the nursing students. METHODS: Study participants were 292 nursing students recruited from 3 universities. Self-reported data were collected in September 2015 from structured questionnaires. Data were analyzed using descriptive statistics, Pearson's correlation coefficient, exploratory factor analyses, and structural equation modeling. RESULTS: Self efficacy and self-control have a direct effect on smartphone addiction in the nursing students. The relationship between depression and smartphone addiction was fully mediated by self efficacy and self-control. However, the relationships of smartphone addiction shares with college adaptation and stress were partially mediated by depression, self efficacy, and self-control. CONCLUSION: Our study findings may be used as baseline information to develop preventive intervention programs for nursing students. Nursing educators and clinicians should encourage students' self-control, improve self efficacy when dealing with those with smartphone addiction, emphasize adaptation to college, and help manage stress and depression.

4.Investigation of Stress-Inducing Factors and Occupational Stress Levels in General and Pediatric Dentists
Journal of Korean Academy of Pediatric Dentistry 2022;49(4):481-496
The purpose of this study was to compare factors causing stress in pediatric and general dentists when treating pediatric patients and to evaluate their overall occupational stress level. A total of 191 dentists participated in the online survey, consisting of 66 pediatric dentists and 125 general dentists. The questionnaire was conducted using Google Form. Both groups were stressed due to poor cooperation of patient and caregiver, uncertain prognosis of treatment, and low cost of pediatric dental treatment. The pediatric dentists felt relatively high stress due to poor cooperation from caregivers and an uncertain prognosis of treatment (p < 0.05). Overall occupational stress was high in both groups in the order of patient, time, job environment, and income-related stress, and the degrees of pediatric dentists were lower than general dentists. Among the 3 sub-factors of occupational burnout, more than 98% of both groups showed burnout in “depersonalization”, and more than 69% of both groups showed burnout in “emotional exhaustion”. Both groups showed a low burnout rate in “reduced sense of accomplishment” and pediatric dentists showed a higher sense of accomplishment than general dentists (p < 0.05). This study showed that both groups were under high occupational stress due to various factors, and efforts were required to relieve stress.

Purpose:
To investigate the postoperative changes in diplopia and evaluate factors that affect diplopia after isolated inferior orbital wall fracture.
Methods:
A retrospective study was conducted on 200 patients who underwent reconstruction surgery for isolated inferior orbital wall fracture between March 2001 and December 2020. Diplopia was categorized into peripheral, central, and full-degree types based on the history and binocular single vision. The natural course of diplopia was analyzed pre-operatively and at 1 day, 6 weeks, and 6 months postoperatively. We analyzed the orbital computed tomography images to determine fracture size (small, medium, or large), fracture site (anterior, middle, posterior, or mixed), extraocular muscle (EOM) size (swelling or deformity), EOM site (incarcerated or prolapsed), and EOM tenting.
Results:
Diplopia was seen in 144 out of 200 patients (72.0%) before surgery; peripheral diplopia was seen in 57 patients (39.6%), central diplopia in 46 (24.3%), and full-degree diplopia in 20 (13.9%). Pre-operative diplopia differed according to the pre-operative limitation of range of motion (LOM) (p < 0.001) and EOM site (p = 0.022). Pre-operative diplopia type differed according to the LOM direction (p = 0.018) and EOM size (p = 0.020). Diplopia persisted in 33 patients (16.5%) 6 months after the surgery. Recovery was faster in patients with peripheral diplopia compared to those with central or full-degree diplopia.
Conclusions
The presence of diplopia was associated with the pre-operative LOM and EOM site but the type of diplopia was associated with LOM direction and EOM size. These factors can be used to predict the progression of diplopia in patients with isolated inferior orbital wall fracture.

Ectopic parathyroid adenomas of the retropharyngeal space are relatively rare. Herein, we report a case of primary hyperparathyroidism (PHPT) secondary to a retropharyngeal parathyroid adenoma. A 22-year-old woman presented with elevated serum calcium and parathyroid hormone (PTH) levels, revealed during a medical check-up. The patient had a history of ureteral stones and a confirmed low bone mass. Neck 99mTechnetium-sestamibi singlephoton emission computed tomography (CT) and ultrasonography did not reveal any suspicious lesions. There was no evidence of hereditary PHPT based on the results of targeted gene sequencing. Surgical exploration was unsuccessful, and the PHPT persisted after the first surgery. Approximately a year after the failed operation, 18F-fluorocholine (FCH) positron emission tomography/CT (PET-CT) became available, and when performed, it revealed increased uptake in the retropharyngeal space of the right side of the neck. The results of parathyroid venous sampling were concordant with a >2-fold elevation of PTH level in the veins on the right side of the neck compared to the peripheral veins. The 1.8 cm-diameter mass was successfully removed resulting in an 87% reduction in intraoperative PTH level (198.0-26.5 pg/mL). Subsequently, normalizations of calcium and PTH levels were achieved. In summary, ectopic parathyroid adenomas, including retropharyngeal lesions, should also be suspected when investigating an elusive case of PHPT. 18F-FCH PET-CT can be a useful complementary modality for detecting culprit lesions.

OBJECTIVES: Perceived stress scale is a self-report inventory to estimate the degree of individual perceived stress in daily life. The aim of this study was to introduce this scale and test the reliability and validity of the Korean version of PSS. METHODS: The total of 154 female hospital workers were included in this study. The survey questionnaires were conducted for demographic information. All participants were required to complete PSS, Hamilton Anxiety scale and Beck Depression Inventory. Reliability and validity studies were conducted and internal consistency was examined. RESULTS: The mean score of the PSS reported in this sample was 20.69+/-4.56. The overall Cronbach's alpha was 0.819, and the test-retest reliability coefficient was 0.66. PSS had a significant positive correlation with the HAM-A(r=0.49, p<0.01), and the BDI(r=0.55, p<0.01). Factor analysis yielded 2 factors with eigenvalues of 3.924 and 2.608, accounting for 65 percent of variance. Factor 1 represented "stress" and factor 2 represented "control of stress". CONCLUSIONS: This study indicates that the PSS is appropriate for estimating the perceived stress levels. These results support the use of PSS in large sections of the population in Korea.

PURPOSE: In the present study, we investigated the treatment efficacy and clinical outcomes of botulinum neurotoxin-A (BoNT-A) administered for longer than 5 years to patients with essential blepharospasm. METHODS: We retrospectively reviewed 19 patients (male : female = 8 : 11) diagnosed with essential blepharospasm between March 2006 and July 2016 who underwent BoNT-A injections for over 5 years and were followed. Efficacy of 297 injections of Botox (n = 162), Meditoxin (n = 75), Hugel-tox (n = 40), or Dysport (n = 20) was based on the symptom improvement score at the final injection (−1, worse; 0, same; 1, better). Injection dose (botox unit), duration of efficacy (months), and adverse events were also investigated. RESULTS: Based on product type, significant differences in patient age (59.3 ± 9.8 years), disease period (5.0 ± 5.4 years), number of botulinum neurotoxin injections before visiting our clinic (1.6 ± 2.6), and follow-up period (7.2 ± 1.6 years) were not observed. Treatment efficacy score and injection dose of repetitive injections were 0.1 ± 0.5 and 39.1 ± 4.0 units, respectively, and did not show significant differences with repeated injections. Duration of response was 5.9 ± 5.4 months, but this significantly decreased as the injections were repeated (p < 0.01). Among the 297 injections, adverse events occurred 12 times (4.0%) with no severe sequelae. CONCLUSIONS: In this study, we showed that repetitive, long-term BoNT-A injections are considered a stable and effective treatment for essential blepharospasm in terms of consistent injection dose and maintenance of treatment efficacy. However, the duration of long-term efficacy could be decreased in patients injected repetitively.

Journal of the Korean Ophthalmological Society 2018;59(11):1071-1076
PURPOSE: To report a case of immunoglobulin G4 (IgG4)-related ophthalmic disease associated with adult xanthogranulomatous disease. CASE SUMMARY: A 38-year-old male with a history of cholecystectomy visited our clinic for bilateral periorbital swelling. Histopathology of the orbital biopsy showed diffuse infiltration of foamy histiocytes with Touton giant cells and lymphoid follicles, with a diagnosis of adult-onset xanthogranuloma. After excisional biopsy, he was treated with azathioprine and prednisolone. Four years after treatment, he again visited the clinic due to bilateral, yellowish eyelid masses. Serological examinations were all nonspecific findings, except for elevation of IgG and IgG4 levels. Magnetic resonance imaging showed bilateral symmetric soft tissue enlargement with slightly heterogeneous T1/T2 isosignal intensity, with contrast enhancement at the superolateral aspect of extraconal spaces. Excisional biopsy and blepharoplasty were performed. Immunohistochemical sections showed that the IgG4+/IgG plasma cell ratio was 10–20% and the IgG4 plasma cell count was 22/high power field (HPF). His past sections of 2013 from the pathology department were again stained and showed that the IgG4+/IgG plasma cell ratio was 40–50% and the IgG4 plasma cell count was 59/HPF. Thus, he was definitely diagnosed with IgG4-related ophthalmic disease. CONCLUSIONS: If there is recurrent eyelid swelling, IgG4-related ophthalmic disease should be considered as a differential diagnosis. And the patient with adult xanthogranulomatous disease can be diagnosed with IgG4-related ophthalmic disease.
