Purpose: The purpose of this study was to identify the influence of workplace bullying and resilience on depression of hospital nurses. Methods: A cross-sectional, descriptive correlational study design was used. Participants were 134 nurses from three general hospitals in two provinces. Data were collected July 20-August 29, 2019. Collected data were analyzed with descriptive statistics, independent t-test, one-way ANOVA with the Sheff’s test, Pearson's correlation coefficient, and hierarchical multiple regression using SPSS/WIN 20.0 program. Results: Multiple regression analysis revealed that workplace bullying (β=.43, p<.001), resilience (β=-.33, p<.001) of participants were significant factors with explanation power approximately 38% of the variance on depression. Conclusion The findings suggest that it is necessary to develop the strategies to prevent workplace bullying for fostering the safe psychosocial work environments and to improve the individual resilience of hospital nurses to reduce their depression.

PURPOSE: To evaluate of the range and relationship between intraocular pressure (IOP), and central corneal thickness (CCT) in premature infants. METHODS: To investigate the correlation of IOP and CCT with gestational age and body weight, 58 premature infants 37 weeks-old or younger were examined. Under topical anesthesia, IOP was measured with Tono-Pen(R) XL (Medtronic Solan, Jacksonville, FL) and the CCT with pachymeter (SP-2000, TOMEY(R), Japan). The fundus was examined in infants with a risk of retinopathy of prematurity (ROP). RESULTS: Average gestational age of the subjects was 33 weeks and 6 days and body weight was 1506+/-520 grams (mean+/-standard deviation). Forty-five subjects had oxygen therapy, and 10 patients were found to have any one of the stages of ROP. Average IOP was 15.14+/-4.64 mmHg in the right eye and 15.29+/-3.70 mmHg in the left eye. CCT was 594.72+/-74.87 micrometer in the right eye and 599.78+/-74.17 micrometer in the left eye. No statistically significant correlation was found between IOP or CCT and gestational age or body weight. CONCLUSIONS: Gestational age and body weight did not appear to affect IOP or CCT in the gestational age between 26 and 37 weeks. The maturing eye in the neonate is known for fast development in the first year after birth. There are, however, few reports in the literature regarding the changes in dimensions of ocular structures in the premature neonate. These normative values may aid ophthalmologists in assessing IOP and CCT in premature infants.

PURPOSE: To evaluate the efficacy of preoperative intravitreal bevacizumab (Avastin(R); Genetech, San Francisco, CA, USA) injections of pars plana vitrectomy (PPV) for proliferative diabetic retinopathy (PDR). METHODS: Thirty patients (30 eyes) who underwent PPV for treatment of PDR and received a preoperative intravitreal bevacizumab injection of 1.25 mg were retrospectively analyzed. The study group (group 1, 30 patients, 30 eyes) was compared with a control group (group 2, 29 patients, 30 eyes and matched with the study group for preoperative parameters) who underwent PPV without preoperative intravitreal bevacizumab injection. RESULTS: In both groups, visual acuity improved but there was no statistical significance. Intraoperative vitreous hemorrhage occurred in 14 eyes (46.7%) from group 1 and 11 eyes (36.7%) from group 2. There was no statistical significance of intraoperative bleeding occurrence (p=0.3). Postoperative vitreous hemorrhage occurred in 4 eyes from group 1 and 14 eyes from group 2. The group 1 had a lower incidence of postoperative hemorrhage than group 2 (p=0.005). CONCLUSIONS: Preoperative intravitreal bevacizumab injection appears effective in decreasing early postoperative vitreous hemorrhage and maybe technically helpful in PPV for PDR.

PURPOSE: To evaluate changes in muscle length when retracting the extraocular rectus muscle with muscle hooks during strabismus surgery. METHODS: Forty-four rectus muscles of 42 patients consecutively resected in two hospitals (A, B) were included in this study. After isolation of the rectus muscle, the length of the muscle was recorded and the portion to be resected was marked using gentian violet stain on the tip of calipers. After the rectus muscle was retracted with two muscle hooks in either direction, its length was measured again with the calipers. RESULTS: The length of the rectus muscle was not changed by retraction in 25 of 44 muscles (56.8%). The length of the muscle was changed by 0.5 mm in 13 muscles (29.5%) and by 1mm in six muscles (13.6%). Changes of rectus muscle length over 0.5 mm were observed in 15 of 27 muscles of patients treated at hospital A (55.5%) and four of 17 muscles of patients treated at hospital B (23.5%). The results for the two hospitals were significantly different (p=0.037). CONCLUSIONS: Small errors in measurement can occur when muscle resections are performed during strabismus surgery. Institutional or clinician related factors may explain variations in error rates between hospitals.

The scabies mite is an ectoparasite, which is able to infest humans. The incidence of scabies decreased during the past 20 years in Korea. However, the incidence is likely to increase again, and may be delayed or missed diagnosis recently. Its clinical presentation is typical, although in a host with compromised immune system, like the mentally retarded and elderly patients, the clinical presentation may be altered. Because a delay in diagnosis may induce rapid spread of the scabies mite, immediate diagnosis and treatment are necessary. We report two cases of scabies in elderly patients from different nursing homes. These patients were transferred to our center for treatment of pneumonia and chronic renal disease. They revealed pruritus and skin rashes after the treatment of further underlying diseases. We consulted to a dermatologist because of worsening symptoms, despite an application of medication with antihistamine and topical steroid, scabies was diagnosed. The symptom improved with topical 1% gamma-benzene hexachloride, an effective scabies drug. We suggest that geriatrists should suspect scabies who presents with pruritus that is persistent or resistant to conventional treatment, especially patients transferred from nursing homes.

BACKGROUND: Microscopic examinations are usually performed to confirm urine sediments in samples flagged in automated urinalysis. The aim of this study was to analyze the review rates and the difference in urinalysis results according to review rules. METHODS: A total of 1,408 urine samples submitted for health screening were collected. The urine chemistry test and urine sediment test were performed using EikenUS 3100 (Eiken Chemical Co. Ltd., Japan) and Sysmex UF-1000i (Sysmex Co., Japan), respectively. We assessed the rate of agreement between the 2 analyses and the kappa values for white blood cells (WBCs) and red blood cells (RBCs). Microscopic examinations were performed for all cases of discordant results between the urine strip and automated sediment analysis, some cases of concordant results, and cases of albuminuria. RESULTS: The review rate was 14.3%. Microscopic examinations were additionally performed on 77 samples (77/1,207, 6.4%) including 29 and 56 samples flagged for WBCs and RBCs, respectively. Based on the results of microscopic examination, the false-positive and the false-negative results of the urine chemistry test and automatic sediment analysis were corrected. Among concordant results between two methods, a clinically significant number of false-negatives were identified (6 results of WBC detection [6/125, 4.8%] and 4 of RBC detection [4/145, 2.8%]). Among the 22 unflagged cases of albuminuria, pathologic casts were detected in 21 cases (21/22, 95.5%). CONCLUSIONS: Microscopic examination based on the combined results of the two analyses improved the quality of the test.

PURPOSE: To investigate the influence of the change in medial rectus resection amount caused by traction with muscle hooks on surgical results in exotropia. METHODS: In this prospective study 38 exotropia patients underwent unilateral lateral rectus recession-medial rectus resection (R & R). After isolation of the medial rectus muscle, the length of the muscle was measured with a muscle hook, and the portion to be resected was marked using gentian violet stain with calipers. After the medial rectus was retracted with two muscle hooks in either direction, its length was measured again with the calipers. Group 1 includes the patients with the planned resection amount changed to a more 0.5-1.0 mm when the rectus muscle was retracted, while group 2 did not change with the second muscle hook. The surgical results were compared between the 2 groups at postoperative 6 months. RESULTS: Mean resection amount was changed from 5.07 +/- 0.76 mm to 5.36 +/- 0.73 mm after pulling the second muscle hook. Sixteen patients (42.1%) were included in group 1 and 22 patients (57.9%) in group 2. There was no significant statistical difference in mean preoperative and postoperative deviated angle between the two groups. Success rates defined as the ocular alignment within +/- 10 PD in the primary position at postoperative 6 months were 75.0% in group 1 and 86.3% in group 2, which is not stastistically different (p > 0.05). CONCLUSIONS: Medial rectus resection amounts can be changed with the muscle traction with two muscle hooks, which induced the planned amount of resection less than first measured resection amount. However, there was little influence on surgical outcomes from the change occurred to a maximum 1 mm in resection measurement due to traction with two muscle hooks.

To evaluate the role of serum lipids in the patients with cerebral thrombosis, lipid parameters were compared with a sex- and age - matched healthy control. The cerebral thrombosis group included 61 males (mean age, 61.0) and 32 females (mean age, 66.3). Total cholesterol and total/HDL-cholesterol ratio in the male and female patients were significantly higher than in the control(p<0.001). But triglyceride showed difference only in the male patient group (p<0.05). All parameters did not show any difference between the lacunar and cortical infarctions. The finding in this study support the idea that high serum total cholesterol, low serum HDL-cholesterol and high total / HDL-cholesterol ratio are risk factors for cerebral thrombosis.
