ObjectiveFew studies have focused on the characteristic features of drug overdose in children and adolescents who have attempted suicide in Korea. The present study examined the characteristics of drug overdose in children and adolescents who visited the emergency room following drug ingestion for a suicide attempt.MethodsThe medical records of 28 patients who were treated in the emergency room following a drug overdose from January 2008 to March 2011 were analyzed. Demographic and clinical variables related to the suicide attempts were examined.ResultsThe mean age of the patients was 16.6±1.7 years (range 11-19 years), and 20 of the patients (71.4%) were female. Most of the patients (n=23, 82.1%) overdosed on a single drug; acetaminophen-containing analgesics were the most common (n=12, 42.9%). Depression was the most common psychiatric disorder (n=22, 78.6%), and interpersonal conflict was the most common precipitating factor of the suicide attempts (n=11, 39.3%). This was the first suicide attempt for approximately 80% of the patients. About one fourth of the patients (n=7, 25%) had follow-up visits at the psychiatric outpatient clinic.ConclusionEarly screening and psychiatric intervention for depression may be an important factor in preventing childhood and adolescent suicide attempts. Developing coping strategies to manage interpersonal conflicts may also be helpful. Moreover, policies restricting the amount and kind of drugs purchased by teenagers may be necessary to prevent drug overdose in this age group.
ObjectiveIn recent years there has been an enormous increase of neuroscience research using the facial expressions of emotion. This has led to a need for ethnically specific facial expressions data, due to differences of facial emotion processing among different ethnicities.MethodsFifty professional actors were asked to pose with each of the following facial expressions in turn: happiness, sadness, fear, anger, disgust, surprise, and neutral. A total of 283 facial pictures of 40 actors were selected to be included in the validation study. Facial expression emotion identification was performed in a validation study by 104 healthy raters who provided emotion labeling, valence ratings, and arousal ratings.ResultsA total of 259 images of 37 actors were selected for inclusion in the Extended ChaeLee Korean Facial Expressions of Emotions tool, based on the analysis of results. In these images, the actors' mean age was 38±11.1 years (range 26-60 years), with 16 (43.2%) males and 21 (56.8%) females. The consistency varied by emotion type, showing the highest for happiness (95.5%) and the lowest for fear (49.0%). The mean scores for the valence ratings ranged from 4.0 (happiness) to 1.9 (sadness, anger, and disgust). The mean scores for the arousal ratings ranged from 3.7 (anger and fear) to 2.5 (neutral).ConclusionWe obtained facial expressions from individuals of Korean ethnicity and performed a study to validate them. Our results provide a tool for the affective neurosciences which could be used for the investigation of mechanisms of emotion processing in healthy individuals as well as in patients with various psychiatric disorders.
Serum calcium and phosphorus levels are significantly associated with NAFLD. Further investigation is needed to verify whether calcium and phosphorus levels indicate a higher risk of NAFLD.
Atypical antipsychotics have replaced conventional antipsychotics in the treatment of schizophrenia because they have less of a propensity to cause undesirable neurologic adverse events including extrapyramidal symptoms, tardive dyskinesia, and neuroleptic malignant syndrome (NMS). However, atypical antipsychotics have been known to result in various metabolic complications such as impaired glucose tolerance, diabetes and even diabetic ketoacidosis (DKA). In addition, a number of NMS cases have been reported in patients treated with atypical antipsychotics, although the absolute incidence of neurologic side effects is currently significantly low. Here, we report a patient who simultaneously developed DKA, acute renal failure and NMS with rhabdomyolysis after olanzapine treatment. Olanzapine-induced metabolic complications and NMS were dramatically improved with cessation of the olanzapine treatment and initiation of supportive management including fluid therapy, hemodialysis, and intensive glycemic control using insulin. At short-term follow-up, insulin secretion was markedly recovered as evidenced by a restoration of serum C-peptide level, and the patient no longer required any hypoglycemic medications. Despite the dramatic increase in the use of atypical antipsychotics treatment, individualized treatments along with careful monitoring may be prudent for high risk or vulnerable patients in order to avoid the development of metabolic side effects.
ObjectiveThe aim of the present study was to examine the impact of personality traits on emotional responses to interpersonal stress.MethodsThirty-two healthy college students (18 men, 14 women; age 25.2±2.7 years) participated in the study. Mood and anxiety were assessed with the Beck Depression Inventory and the State Trait Anxiety Inventory. Personality traits were assessed with the Interpersonal Sensitivity Measure (IPSM). The subjective emotional responses of participants to different (i.e., negative, neutral, and positive) interpersonal feedback were measured.ResultsSubject responses were positive to positive interpersonal feedback and negative to negative interpersonal feedback. The IPSM fragile inner self subscore was negatively correlated with the subjective emotional ratings in response to interpersonal feedback. No correlation was found between validation measures (i.e., the degree of attention in the task and task difficulty) and subjective emotional responses.ConclusionsTaken together, emotional responses to interpersonal stress may be modulated by personality traits and may impact health and psychological outcomes. Therefore, proper screening and stress management programs that focus on personality traits may improve the mental health of college students.
Women with uveal melanoma have better survival probabilities relative to men with uveal melanoma. Our findings show a comprehensive picture of survival probability in uveal melanoma cancer patients in Korea, which requires further investigation of mechanism of the sex disparity in uveal melanoma.
Recent studies suggested that a lower serum thyroid hormone level is associated with more vascular calcification. However, it has been rarely evaluated whether lower thyroid hormone levels affect the calcification of thyroid cancer and there is a relationship between calcification patterns of papillary thyroid carcinoma (PTC) and coronary artery calcification (CAC). The study was divided into two groups: First, we retrospectively reviewed 182 PTC patients and examined the correlation between PTC calcification patterns and CAC by coronary computed tomography (CT). Second, the correlation between the calcification pattern of PTC and thyroid hormone concentration was investigated (n = 354). The calcification pattern of PTC was evaluated by thyroid ultrasonography and classified into four groups: no-calcification, microcalcification, macrocalcification, and mixed-calcification. In PTC patients with microcalcification and mixed calcification, more CAC was observed and coronary calcium score (CCS) was higher. Lower free T4 and higher thyroid-stimulating hormone (TSH) levels were associated with microcalcification and mixed calcification, not with macrocalcification and no calcification. PTC with microcalcification and mixed calcification showed more aggressive phenotypes like lymph node metastasis and more advanced TNM (tumor, node, and metastasis) stage than those with no calcification and macrocalcification. Calcification patterns of PTC showed close association with thyroid hormone levels and CAC. Further research is needed to determine how these findings are related to cardiovascular risk and disease-specific mortality.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
