A 49-year-old female presented with bilateral abducens nerve palsies. She had 75 prism diopter esotropia. The extraocular movement of the lateral rectus was -1 limitation for the right eye and -4 limitations for the left. After performing orbital magnetic resonance imaging (MRI), 2 mL of bupivacain (5 mg/mL) was injected into the left lateral rectus (LR). One month after injection, a further orbital MRI was performed. Subsequently, recession of both medial rectus (6 mm) and resection of the left LR (9 mm) were performed. After one month, bupivacaine had no hypertrophic effects. There was little change in angle of deviation. The orbital MRI scan showed a 1.91% increase in volume compared to the muscle prior to the injection. Histological findings showed no muscle fibers of the left LR muscle, only the fiber nucleus and the collagen that replaced the fibers. We report on the changes in stiffness and muscle volume and on the histology of the muscle one month after injecting bupivacaine into the paralyzed left LR muscle combined with standard surgical treatment.

PURPOSE: The purpose of this study was to investigate the clinical features of neonatal seizures and to identify prognostic factors of neurodevelopmental outcome in term infants who experienced clinical seizures. METHODS: A retrospective analysis was performed on 153full term and preterm infants with seizures from January 2008 to December 2013. Binary logistic regression analysis was applied to assess risk factors associated with neurological adverse outcomes using variables that were found to be significant on univariate analysis. RESULTS: During the study period, 102 (66.7%) term and 51 (33.3%) preterminfants were enrolled. The main cause of neonatal seizures was hypoxic ischemic encephalopathy (24.5%) in term infants and intracranial hemorrhage (74.5%) in preterm infants. The most common type of seizure was focal clonic seizure. Generalized tonic seizure was more commonly observed in preterm than in term infants. 39 out of 56 term infants with at least 12 months of neurologic follow-up showed normal outcomes while only one preterm infant showed normal development.Prognostic factors related to adverse neurodevelopmental outcomes in term infants were perinatal history of fetal distress, etiology of hypoxic ischemic encephalopathy, severity of EEG(Electroencephalogram) abnormality, evidence of hypoxic ischemic encephalopathy on brain magnetic resonance imaging, and the need for multiple antiepileptic drugs for seizure control. CONCLUSION: Preterm infants showed poorer neurodevelopmental outcomes compared to term infants. The etiology of seizures, treatment response, neuroimaging and electroencephalographic findings were important in predicting the developmental outcome in term infants with seizures.

Objective: In numerous studies that have addressed transcranial direct current stimulation (tDCS) devices, participants visit the hospital regularly and undergo stimulation directed by health professionals. This method has the advantage of being able to deliver accurate stimuli in a controlled environment, but it does not adopt the merits of tDCS portability and applicability. Thus, it may be necessary to investigate how self-administered tDCS treatment at home affects depression-related symptoms. Methods: In this randomized, single-blinded clinical trial, 58 patients with major depressive disorder were assigned to active and sham tDCS stimulation groups, and treatment responses were evaluated biweekly over six weeks. Both active and sham tDCS treatment group were treated with escitalopram. All participants were instructed the protocol and usage of at-home tDCS device, and self-administered tDCS treatment at their home. Results: The beck-depression inventory score decreased significantly as treatment progressed, and the degree of symptom improvement was significantly higher in the active group than in the sham tDCS group. There were no significant differences between the two groups in other indices, including the Hamilton Depression Scale. Conclusion These results suggest that patient-administered tDCS treatment might be effective in improving subjective symptoms of depression.

Background and Objectives: With the introduction of sialendoscopy, minimal invasive surgery has become possible for the removal of sialoliths, although sialendoscopic removal of parotid stones remains a surgical challenge. Sialendoscopic stone removal can be differently applied according to the location and size of stones. This study was conducted to evaluate the surgical outcomes of sialaendoscopic stone removal and to provide a strategy for choosing an adequate surgical approach according to the characteristics of parotid stones.Subjects and Method A retrospective study was conducted of 43 patients with parotid sialolithiasis who were treated by sialendoscopic stone removal between March 2017 and January 2021. Surgical techniques were classified into sialendoscopy alone (SA), sialendoscopy-assisted transoral approach (STO), and sialendoscopy-combined retroauricular approach (SRA). The parotid gland stones were categorized by size, location, and multiplicity. Results: Of the 43 patients, 13 patients underwent SA, 10 received STO, and 20 were treated with different SRA approaches. The SRA approaches included three distal, seven proximal, and ten intraglandular stone removal cases. The success rate of stone removal was 92% (12 cases) by SA, 90% (9 cases) by STO, and 100% (20 cases) by SRA. In cases of SA and STO, all patients had distant stones except for one who had proximal stones. Postoperative complications including pain, swelling, wound dehiscence, sialocele, duct stricture, and facial palsy mainly occurred in cases treated with SRAs. Conclusion Appropriate use of various sialendoscopy-assisted approaches is mandatory to preserve the gland and minimize surgical complications in patients with different features of parotid gland stones.

OBJECTIVE: The suicide rate in South Korea was the second highest among the Organization for Economic Cooperation and Development countries in 2017. The purpose of this study is to understand the characteristics of people who died by suicide in Korea from 2013–2017 and to better prevent suicide. METHODS: This study was performed by the Korea Psychological Autopsy Center (KPAC), an affiliate of the Korea Ministry of Health and Welfare. According to the Korea National Statistical Office, the number of suicide victims nationwide was estimated to reach about 70,000 from 2013 to 2017. Comprehensive suicide records from all 254 police stations in South Korea were evaluated by 32 investigators who completed a 14-day didactic training program. Then, we evaluated the characteristics of suicide victims in association with disease data from the National Health Insurance Database (NHID), which is anonymously linked to personal information of suicide victims. RESULTS: Thirty-one of 254 police stations in the Seoul metropolitan area were analyzed by August 10, 2018. Findings showed that the characteristics of suicide victims differed according to the nature of the region. CONCLUSION: Our results suggest that different strategies and methods are needed to prevent suicide by regional groups.

Acute pancreatitis (AP) rarely occurs in association with food allergy (FA), and the mechanism is not clearly explored. We herein report a rare case of egg protein-induced AP. A 5-year-old girl was brought to the hospital because of tongue pruritus and an increased level of egg white-specific immunoglobulin E. During an oral food challenge, she developed hives, abdominal pain and vomiting after ingestion of a cumulative of 610 mg of boiled egg white (70 mg of protein). After management with intramuscular injection of epinephrine and orally administered prednisolone and levocetirizine, her skin symptoms improved. The next day, blood tests showed elevated levels of amylase and lipase, and computed tomography revealed a swollen pancreas with a low-attenuated necrotic portion. She was diagnosed with AP and treated with food restriction, intravenous methylprednisolone and gabexate mesilate. The serum levels of amylase and lipase were reduced to normal levels on day 5 and her symptoms completely resolved on day 10. A suspicion of food-induced AP is required for correct diagnosis and proper management in children with FA when they manifest severe abdominal pain.

Objective: We aimed to investigate the characteristics of frequent emergency department (ED) users in Korea. Methods: We analyzed the Korea Health Panel Study data of a sampled population from the 2005 Population Census of Korea data, and adults (age ≥18 years) who visited the ED at least once a year between 2014 and 2017 were included in the study. People who visited three or more times a year were classified as frequent users. We compared demographic, socioeconomic, and health-related factors between nonfrequent and frequent users. We used a multivariable logistic regression analysis to determine factors related to frequent ED visits. We also compared the characteristics of ED use in both nonfrequent and frequent users. Results: A total of 5,090 panels were included, comprising 6,853 visits. Frequent users were 333 (6.5% of all panels), and their ED visits were 1,364 (19.9% of all ED visits). In the multivariable regression analysis, medical aid coverage (adjusted odds ratio [aOR] of the National Health Service coverage, 0.55; 95% confidence interval [CI], 0.40–0.75), unemployment (aOR of employment, 0.72; 95% CI, 0.56–0.91), prior ward admission in a year (aOR, 2.14; 95% CI, 1.67–2.75), and frequent outpatient department use (aOR, 1.72; 95% CI, 1.35–2.20) were associated with frequent use. Moreover, frequent users visited the ED of public hospitals more often than than nonfrequent users (19.2% vs. 9.8%). Medical problems rather than injury/poisoning were the more common reasons for visiting the ED (84.5% vs. 71.2%). Conclusion We found that frequent ED users were likely to be those with socioeconomic disadvantage or with high demand for medical service. Based on this study, further studies on interventions to reduce frequent ED use are required for better ED services.

Objective: Although the effects and safety of transcranial direct current stimulation (tDCS) treatment in depressive patients are largely investigated, whether the self-administration of tDCS treatment at patient’s home is comparable to clinic-based treatment is still unknown. Methods: In this single-arm, multi-center clinical trial, 61 patients with mild to moderate major depressive disorder were enrolled. tDCS treatment was delivered at the patient’s home once a day, 5 to 7 times a week for 6 weeks, and each session lasted for 30 minutes. The primary outcome was a total Beck-Depression Inventory-II score, and no concurrent antidepressants were used. Results: The remission rates in both Full-Analysis (FA) (n = 61) and Per-Protocol (PP) (n = 43) groups were statistically significant (FA: 57.4% [0.44−0.70], PP: 62.8% [0.47−0.77]; percent [95% confidence interval]). The degree of depression-related symptoms was also significantly improved in 2, 4, and 6 weeks after the treatment when compared with baseline. There was no significant association between treatment compliance and remission rate in both FA and PP groups. Conclusion These results suggest that acute treatment of patient-administered tDCS might be effective in improving the subjective feeling of depressive symptoms in mild to moderate major depressive disorder patients.
