Purpose: The correlation between the existence of the preoperative condition of ≥10 prism diopters (PD) in patients with basic type of intermittent exotropia (IXT) and postoperative outcomes was analyzed.
Methods: The medical records of patients that underwent surgery for IXT were analyzed retrospectively. The analysis was conducted by dividing the patients into a group with change of <10 PD (group 1) and ≥10 PD (group 2) before the time of the surgery. Patients who received at least 6 months of follow-up after surgery were included. The age, sex, angle of deviation and stereoacuity of the patients were studied. Surgical success was defined as exodeviation of <10 PD or esodeviation of <4 PD at the final visit after the surgery. The correlation between clinical factors and surgical success rate was analyzed by using correlative analysis.
Results: A total of 129 patients participated in the study. There were 108 (83.7%) and 21 (16.3%) patients in groups 1 and 2, respectively. There were 89 (82.4%) and 17 (80.1%) patients with surgical successes in groups 1 and 2, respectively (p = 0.18). Moreover, 13 (12.0%) patients in group 1 and three (14.3%) patients in group 2 required reoperation, showing no significant difference (p = 0.12). There was no statistically significant correlation between surgical success and preoperative change of angle of deviation <10 PD (odds ratio, 1.78; p = 0.17).
Conclusions Among the patients with basic type of IXT subjected to the analysis, 16.3% had a change of ≥10 PD before surgery, and there was no significant correlation between surgical success and preoperative change of angle of deviation.

Mucormycosis is a highly aggressive and fatal fungal infection. Due to its rapid progression, combination of early wide surgical debridement with administration of antifungal agent is extremely crucial. European Society for Clinical Microbiology and Infectious Diseases, and European Confedration of Medical Mycology recommended amphotericin B as the first-line of treatment and posaconazole as the salvage agent for mucormycosis. We report a case of rhino-orbital-cerebral mucormycosis successfully treated by changing antifungal agent from the first-line amphotericin B to the salvage agent posaconazole. A 57-years-old female with uncontrolled type 2 diabetes mellitus was presented with foot abscess and rhino-orbital-cerebral mucormycosis. The infection was intractable despite orbital orbital exenteration with surgical debridement and 2 months of antibiotics treatment including amphotericin B. Changing amphotericin B to posaconazole resulted in clinical improvement within the first week. Conclusively the newly administered antifungal agent, posaconazole is expected to be an effective salvage treatment option for mucormycosis after failure of initial treatment of amphotericin B with surgical management.

BACKGROUND: Fungal infections are frequent encountered conditions presented in various clinical forms. The prevalence of fungal infection is gradually growing because of the increase in aged population and immune-compromised host which is susceptible factor of fungal infection. Broad array of studies of fungal infection have been published in Korea. However, epidemiologic study of fungal infection in admitted patients via emergency department has not been conducted. OBJECTIVE: The purpose of this study is to generate background data for emergency department visits in relation to fungal infection for developing a subsequent management and control system. METHODS: The data was collected from National Emergency Department Information System (NEDIS) in Korea from 2011 to 2013. Data analysis was done to evaluate the age distribution of admission, regional variance and sex of the patients with fungal infection. RESULTS: The patients were divided into five groups according to their primary diagnosis which were skin fungal infection, subcutaneous mycoses, opportunistic mycoses, systemic mycoses and other mycoses. The annual admission ratio of general fungal infections increased from 2.15 persons per 100,000 in 2011 to 2.46 persons per 100,000 in 2013. The highest admission ratio was seen in opportunistic mycoses group followed by cutaneous fungal infections, other mycoses, subcutaneous mycoses and systemic mycoses groups. CONCLUSION: This study provides a basic set of data pertaining to fungal infections in emergency departments. Therefore, more systemically approached researches are required to implement sounder management and control systems of fungal infections presented in emergency departments.

OBJECTIVE: The purpose of this study was to compare the discontinuation rate of widely prescribed atypical antipsychotics when administered to newly admitted, acutely ill patients with schizophrenia or bipolar mania. METHODS: Medical records of patients admitted to psychiatric ward of two university hospitals between January 2007 and December 2008 were retrospectively reviewed. Subjects were eligible for inclusion if they prescribed olanzapine, risperidone or aripiprazole for their psychotic or manic symptom control. Patient groups (olanzapine/risperidone/aripiprazole) were compared for rate of antipsychotics discontinuation and duration of treatment continuation. RESULTS: There was no statistically significant difference in the rates of discontinuation during hospitalized period between olanzapine, risperidone and aripiprazole. Rates of discontinuation were 14.5% for olanzapine, 18.6% for aripiprazole and 24.0% for risperidone. Predictor of treatment discontinuation was short titration period and long illness duration. CONCLUSION: This study demonstrated that risperidone, olanzapine and aripiprazole were comparable with no difference found on the discontinuation rate in treating acutely ill psychiatric patients. However, the small number of patients who participated in this study made it difficult to establish significance.

Background: Cataracts are the leading cause of impaired vision or blindness in dogs. There are many antioxidants that can prevent cataract progression, but whether they are clinically effective in dogs has not been established. Objectives: To analyze the delaying or preventing effect of oral antioxidants on canine senile cataracts through retrospective analysis. Methods: Medical records of dogs from January 1, 2015 to July 10, 2020 were reviewed. Dogs that were 8 yr of age or older with senile cataracts were included in this study. The dogs were divided into two treatment groups (dogs administered with Ocu-GLO supplement and dogs administered with Meni-One Eye R/C supplement) and a control group (dogs that were not administered any supplement). Dogs with incipient and immature cataracts were included in this study. Altogether, 112 dogs (156 eyes) with incipient cataracts and 60 dogs (77 eyes) with immature cataracts were included. The period of time that cataracts progressed from incipient to immature, and from immature to mature was recorded for each dog. Results: There was no significant delaying effect on the progression of incipient cataracts.However, both Ocu-GLO (hazard ratio = 0.265, p = 0.026) and Meni-One (hazard ratio = 0.246, p = 0.005) significantly delayed the progression of immature cataracts compared to the control group. Conclusions Although there was no significant delaying effect of oral antioxidants on incipient cataract progression, antioxidants could be used to delay the progression of senile immature cataract.

Background: There is little data regarding types of idiopathic premature ventricular complex (PVC) according to heart rate dependence. Methods: One hundred and sixty-eight patients with idiopathic PVC were enrolled in this study. Evaluation of the number of PVCs and total ventricular beats, and the density of PVC was done using 24 h Holter monitoring. Patients were divided into groups as having: fast rate-dependent (Group I), slow rate-dependent (Group II), and heart rateindependent PVC (Group III) based on the relationship between the number of hourly PVC and hourly heart rate. After ß-blocker medication, 24 h Holter monitoring was repeated. Results: Among the 168 subjects, 66 (39.3%) patients were in Group I, 18 (10.7%) in Group II, and 84 (50.0%) in Group III. There were no significant differences in the baseline number of PVCs and total ventricular beats, and the density of PVC among the three groups. The number of PVCs was significantly reduced in patients with Group I (14,030 ± 11,463 beats/day vs. 7401 ± 10,464 beats/day, p < 0.001), and total ventricular beat was significantly reduced in patients with Group I (109,223 ± 17,564 beats/day vs. 96,182 ± 15,594 beats/day, p < 0.001) and Group III (106,515 ± 13,468 beats/ day vs. 97,995 ± 12,960 beats/day, p < 0.001) after ß-blocker medication. The density of PVC was significantly reduced only in patients of Group I (12.9 ± 10.3% vs. 7.4 ± 10.3%, p = 0.001) after ß-blocker medication. Conclusions The type of PVC according to the heart rate dependence should be considered when treating idi‑ opathic PVC with ß-blockers.
