PURPOSE: To report two cases of spontaneous suprachoroidal hemorrhage associated with wet type of age-related macular degeneration (ARMD) and systemic hypertension. CASE SUMMARY: Two women, aged 76 and 73 years, with a history of systemic hypertension for more than ten years had been treated in an eye clinic for wet type of ARMD. The 76-year-old woman was scheduled to receive an injection of intravitreal Lucentis(R) but experienced sudden onset loss of vision and ocular pain in her left eye. The 73-year-old woman had received no specific treatment for wet type of ARMD. She also complained of visual disturbance and ocular pain. In these two cases, slit lamp or B-scan examination disclosed suprachoroidal hemorrhage. Surgical intervention relieved the ocular pain and symptoms in both cases. CONCLUSIONS: Even if a patient has not received systemic anticoagulation/thrombolytic therapy, if wet-type ARMD patients are elderly and have systemic hypertension, they should receive regular follow-ups because old age and systemic hypertension are risk factors of spontaneous suprachoroidal hemorrhage.

OBJECTIVE: A considerable proportion of suicide attempts are the result of sudden desires. Understanding such impulsive suicide attempts is necessary for effective interventions. We evaluated the impulsivity of suicide attempters treated in emergency rooms. The aim of the study was to identify the characteristics of impulsive suicide attempts by comparing these individuals to those who attempted to commit suicide in a non-impulsive manner. METHODS: This study analyzed suicide attempters who visited the emergency departments of seven selected university hospitals. A total of 269 medical records in which impulsivity of suicide attempt were confirmed were subject to be analyzed. The impulsivity of the suicide attempt was examined using a summative score of items 6 and 15 on the Suicide Intent Scale. RESULTS: A total of 48.0% of the participants were impelled by sudden inclinations to attempt suicide. Impulsive attempters were younger, unmarried and less physical illness than non-impulsive attempters, whereas no significant differences were found on psychiatric history and previous suicide history. Impulsive suicide attempters had suicide ideations that were not as severe (χ2=55.33, p<0.001) or intense (t=-8.38, p<0.001) as their counterparts'. Furthermore, medical results of impulsive suicide attempts were better than non-impulsive suicide attempts (t=-3.77, p<0.001). CONCLUSION: The results suggested that a considerable proportion of suicide attempts were the result of sudden inclinations. Impulsive attempts were made in relatively earlier stages of suicide ideation; consequently, they have less intent than non-impulsive attempts.

OBJECTIVES: In the current study, we investigated the general characteristics of suicide attempters and attempted to determine factors contributing to suicide attempt by analyzing severe suicide ideation and intent. METHODS: This study analyzed medical records of suicide attempters who visited the emergency departments. Data were collected from 7 university hospitals nationwide. As an evaluation measure of suicide intent, we used Suicide Intent Scale (SIS). Colombia Suicide Severity Rating Scale (C-SSRS) was applied for assessment of severity and intensity of suicide idea and lethality of suicide behavior. RESULTS: Male gender, old age and living alone group showed higher SIS score. Male gender, low income, and having psychiatric diagnosis or suicide history group showed a high score on the severity subscale of suicide ideation of C-SSRS. Old age, low income, and having psychiatric diagnosis showed a high score on the intensity subscale of suicide ideation of C-SSRS. Actual lethality scale of C-SSRS was high in male gender and old age group. Severity and intensity of suicide ideation and suicide intent showed positive correlation with actual lethality of suicide behavior. CONCLUSION: Male gender, old age, living alone, psychiatric diagnosis, and suicide history were risk factors affecting severity and intensity of suicide ideation and intent of suicide. Severity and intensity of suicide ideation and intent are positively related to lethality of suicide behavior.

Purpose: This study investigated knowledge, attitudes, and nursing stress related to lifesustaining treatment among oncology nurses. Methods: A descriptive study design was used. Data were collected through a survey from April 1 to May 31, 2022. The participants were 132 nurses working in the oncology ward of a tertiary hospital in Seoul. Data were analyzed using the SPSS 25.0 program with descriptive statics, the independent t-test, analysis of variance, and Pearson correlation coefficients. Results: The average scores for knowledge, attitudes, and nursing stress related to life-sustaining treatment were 14.42, 3.29, and 3.96, respectively. Significant differences in knowledge about life-sustaining treatment were observed based on clinical experience (P=0.029) and education about life-sustaining treatment (P=0.044). Attitudes toward life-sustaining treatment varied significantly with education about life-sustaining treatment (P=0.014), while stress levels differed significantly across working units (P=0.004). A positive correlation was found between the dilemma of extending or stopping life-sustaining treatment (a subdomain of nursing stress) and attitudes toward life-sustaining treatment (r=0.260, P=0.003). Conclusion There was no significant correlation between the nursing stress experienced by oncology nurses and their knowledge and attitudes toward life-sustaining treatment. However, a more positive experience with life-sustaining treatment education was associated with higher stress levels related to the dilemma of extending or stopping life-sustaining treatment. Therefore, it is crucial to develop strategies to manage this dilemma and reduce stress in the field.

Absence seizures (AS) are generalized non-convulsive seizures characterized by a brief loss of consciousness and spike-and-wave discharges (SWD) in an electroencephalogram (EEG). A number of animal models have been developed to explain the mechanisms of AS, and thalamo-cortical networks are considered to be involved. However, the cortical foci have not been well described in mouse models of AS. This study aims to use a high density EEG in pathophysiologically different AS models to compare the spatiotemporal patterns of SWDs. We used two AS models: a pharmacologically induced model (gamma-hydroxybutyric acid, GHB model) and a transgenic model (phospholipase beta4 knock-out, PLCβ4 model). The occurrences of SWDs were confirmed by thalamic recordings. The topographical analysis of SWDs showed that the onset and propagation patterns were markedly distinguishable between the two models. In the PLCβ4 model, the foci were located within the somatosensory cortex followed by propagation to the frontal cortex, whereas in the GHB model, a majority of SWDs was initiated in the prefrontal cortex followed by propagation to the posterior cortex. In addition, in the GHB model, foci were also observed in other cortical areas. This observation indicates that different cortical networks are involved in the generation of SWDs across the two models.

Maturity-onset diabetes of the young (MODY) is a rare, autosomal dominant disease characterized by non-ketogenic diabetes mellitus (DM). MODY type 4, caused by PDX1 mutation, is a very rare subtype of MODY, especially in Korea. We report a case of a 10-year-old, nonobese girl with a family history of type 2 DM. After diagnosis, the patient’s serum glucose level was well controlled using metformin monotherapy; however, the glycated hemoglobin level increased to 9.0% approximately 2 years after treatment. No obesity or lifestyle problems were observed, and serum fasting C-peptide level was within the normal range. Furthermore, no islet-related autoantibodies were detected. A genetic screening for MODY using a next-generation sequencing panel was performed, and a likely heterozygous pathogenic PDX1 mutation (p.Gly246ArgfsTer21) was identified. The PDX1 variant was not detected in her mother, implying that the mutation had arisen de novo in the proband. She was prescribed insulin degludec in addition to metformin therapy, which improved her hyperglycemia. This report presents a novel MODY type 4 phenotype and highlights the importance of genetic screening in patients with MODY characteristics.

Intravascular extension of Wilms tumor (WT) can occur in approximately 4-10% of patients. In general, it does not cause any clinical problems because most of these tumors are small. Although there is no standard treatment currently, preoperative chemotherapy and delayed nephrectomy is generally recommended for children with WT accompanied by tumor thrombus. We report a rare case of WT, aniridia, genitourinary anomalies, and mental retardation (WAGR) syndrome in a boy who also had a huge inferior vena cava thrombus, 7 cm length. The prevalence of bilateral WT and tumor thrombus in WAGR has not been identified. The patient was successfully treated with neoadjuvant chemotherapy to decrease the size of the tumor thrombus with WT and delayed nephrectomy following chemotherapy without any invasive intervention and did not show complications.

OBJECTIVES: The objective of this study was to investigate the relationship between psychological distress and pain in cancer patients. METHODS: 249 patients with cancer who visited National Health Insurance Service Ilsan Hospital between April 2013 and March 2014 were evaluated with National Cancer Center Psychological Symptom Inventory(NCC-PSI) which consisted of Modified Distress Thermometer(MDT) and Modified Impact Thermometer(MIT). Each scale was divided into 3 subscales targeting separate symptoms: insomnia, anxiety, and depression. Psychological distress was defined as positive for those who scored above the cutoff values in at least one of all six subscales. The Numeric Rating Scale for Pain(NRS-Pain) was used to assess the subjective severity of pain. Logistic regression was performed to investigate the association between psychological distress and pain. RESULTS: Univariate logistic regression analysis showed that pain, gender, compliance, and two subscale scores of Hospital Anxiety and Depression Scale(HADS) were significantly associated with psychological distress. Multivariate logistic regression analysis showed that pain and HADS anxiety subscale score maintained a statistically significant association with psychological distress adjusted for variables including age, gender, years of education, Eastern Cooperative Oncology Group performance status, cancer stage, Charlson Comorbidity Index, compliance, and HADS depression subscale score. One point increase in pain was 1.31 times more likely to cause psychological distress. In secondary analysis, pain was significantly associated with all subscales of NCC-PSI, except MIT-anxiety subscale. CONCLUSIONS: This study suggests that NCC-PSI, a screening tool for psychological distress, reflects pain. We recommend that physicians who treat cancer patients consider the examination of psychological distress which provides comprehensive evaluation of various factors regarding quality of life.

This study was conducted to compare the hemostatic efficacy of three ferric subsulfate- and chitosan-based styptics as a powder and a gel containing ferric subsulfate and chitosan (FSC-PO and FSC-G, respectively) and a soaked pad containing ferric subsulfate and lidocaine (FSL-SP) using a rat tail bleeding model. The cytotoxicity of the styptics against L-929 mouse fibroblasts was also evaluated using a cell counting kit-8 assay. Four groups of 10 rats each were assigned to the three different styptics and a non-treated control groups. Rat tail tips were transected, after which styptics were applied with pressure. The wounds were observed for hemostasis for 3 min, then irrigated with saline to check for recurrent hemorrhage. L-929 mouse fibroblasts were exposed to extracts of the styptics (100 mg/mL) and their dilutions (1:10, 1:100, and 1:1,000). FSC-PO and FSC-G more effectively controlled initial hemorrhage than FSL-SP (p = 0.033). Additionally, FSC-PO and FSC-G more effectively maintained hemostasis than the control group (p = 0.02 and p < 0.01, respectively). However, all styptics showed enhanced cytotoxicity against L-929 cells in a dose-dependent manner. Therefore, although FSC-PO and FSC-G would be recommended to control hemorrhage, the benefits of styptics must be balanced against the clinical significance of their cytotoxicity.
