BACKGROUND: Intraoperative hypothermia is common in patients undergoing general anesthesia during arthroscopic hip surgery. In the present study, we assessed the effect of heating and humidifying the airway with a heated wire humidification circuit (HHC) to attenuate the decrease of core temperature and prevent hypothermia in patients undergoing arthroscopic hip surgery under general anesthesia. METHODS: Fifty-six patients scheduled for arthroscopic hip surgery were randomly assigned to either a control group using a breathing circuit connected with a heat and moisture exchanger (HME) (n = 28) or an HHC group using a heated wire humidification circuit (n = 28). The decrease in core temperature was measured from anesthetic induction and every 15 minutes thereafter using an esophageal stethoscope. RESULTS: Decrease in core temperature from anesthetic induction to 120 minutes after induction was lower in the HHC group (–0.60 ± 0.27℃) compared to the control group (–0.86 ± 0.29℃) (P = 0.001). However, there was no statistically significant difference in the incidence of intraoperative hypothermia or the incidence of shivering in the postanesthetic care unit. CONCLUSIONS: The use of HHC may be considered as a method to attenuate intraoperative decrease in core temperature during arthroscopic hip surgery performed under general anesthesia and exceeding 2 hours in duration.

Regional anesthesia for non-obstetric surgery in parturients is a method to decrease patient and fetal risk during general anesthesia. Thoracic interfascial nerve block can be used as an analgesic technique for surgical procedures of the thorax. The Pecs II block is an interfascial block that targets not only the medial and lateral pectoral nerves, but also the lateral cutaneous branch of the intercostal nerve. Pecto-intercostal fascial block (PIFB) targets the anterior cutaneous branch of the intercostal nerve. The authors successfully performed a modified Pecs II block and PIFB without complications in a parturient who refused general anesthesia for breast surgery.

OBJECTIVES : This case-based, small scale study was undertaken to identify the characteristics clinical features of children who exhbiit rare prepubertal onset bipolar disorder. METHODS : We analyzed the clinical records of 13 children who had been hospitalized and diagnosed with bipolar disorder. Clinical characteristics and cognitive function of these patients was based on psychiatrists' medical records and psychologists' evaluation reports. RESULTS : Eleven (84.6%) subjects exhibited clinical features of mixed mania and had a chronic clinicalcourse. They never fulfilled the full criteria of the Diagnostic Statistical Manual of Mental disorders- Fourth Edition (DSM-IV) for manic or hypomanic episodes. Mean age at onset of typical symptoms of bipolar disorder was 9.38 (SD=1.80) and mean age at admission was 12.00 (SD=2.45). Twelve (92.3%) had psychiatric comorbidity. Attention-deficit/hyperactivity disorder was the most prevalent comorbid disease and mean age of onset of it was 6.23 (SD=2.17). CONCLUSION : Subjects with prepubertal onset bipolar disorder showed atypical clinical features. These results suggest that most prepubertal onset bipolar disorder patients fail to meet the DSM-IV criteria for typical bipolar I disorder and therefore, we need to develop alternative diagnostic criteria for pediatric bipolar disorder.

The aim of this study is to describe the clinical characteristics of prepubertal- and adolescent-onset bipolar disorder (BD) and to identify any clinical differences between patients with prepubertal- and adolescent-onset BD. We analyzed the clinical records of 53 inpatients with BD. These patients were divided into prepubertal-onset and adolescent-onset groups. We also divided the subjects into narrow, intermediate, and broad phenotypes according to the definitions proposed by Leibenluft and colleagues. Of the total sample, 16 patients (30.2%) were in the prepubertal-onset group and 37 (69.8%) were in the adolescent-onset group. Patients with prepubertal-onset BD were more likely to display an insidious clinical presentation, atypical features, and comorbid psychopathology. And the majority of the subjects, especially in the prepubertal-onset group, were classified under the intermediate and broad phenotypes. These results suggest that the clinical presentation of BD with prepubertal-onset is different from that of adolescent-onset BD. It is inferred that a significant number of patients with prepubertal- and adolescent-onset BD do not meet DSM-IV criteria for mania or hypomania from the results of this study.

OBJECTIVE: The purpose of this study was to compare psychiatric comorbid disorders and psychological outcomes in children and adolescents with Attention-deficit/hyperactivity disorder (ADHD). METHODS: Subjects were divided into a child group (aged under 12 years) and an adolescent group (aged 12 years and above). All subjects were diagnosed with ADHD based on the DSM IV diagnostic criteria using the Kiddie-Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Korean Version (K-SADS-PL-K). The K-SADS-PL-K was also used to evaluate those psychiatric disorders comorbid with ADHD. And the Korean version of the Child Behavior Checklist (K-CBCL) was used to examine the subjects' psychological outcomes. RESULTS: The rate of comorbidity in adolescent group was significantly higher than that in the child group. In particular, the adolescent group had a significantly higher ratio of comorbid conduct disorder and mood disorder than the child group. With respect to the predominantly inattentive type and Not Otherwise Specified, the school subscale scores on the K-CBCL for the children were significantly higher than those for the adolescents. CONCLUSION: These results suggest that the psychiatric comorbidity may differ between adolescents and children with ADHD. Therefore when treating adolescents with ADHD, more careful assessment and treatment targeting a range of comorbidities are needed.

Endotracheal intubation sometimes leads to complications, particularly in patients with anticipated difficult intubation. The GlideScope is preferred because of its high success rate in cases with anticipated difficult intubation. However, complications during the process have been reported. Most minor injuries can be treated after early detection. However, treatment can be difficult if complications occur later. We report a patient who underwent an emergency tracheostomy due to a delayed airway obstruction caused by pharyngeal wall bleeding during intubation with a GlideScope.

OBJECTIVES: Clinical utility of the Short Form of the Samsung Dementia Questionnaire (S-SDQ) as a screening instrument for Mild Cognitive Impairment (MCI). METHODS: Three groups (n=27, Subjective Memory Impairment (SMI); n=41 MCI; n=79, Early Alzheimer's Disease(AD)) recruited from memory clinic were administered a battery of neuropsychological tests including S-SDQ and Korean version-Mini Mental State Examination (K-MMSE). RESULTS: S-SDQ, unlike the K-MMSE, had no association with the age and education of the subjects. Scores of S-SDQ was found to correlate (r=-.496) with scores of K-MMSE. Result of Receiver Operating Characteristic (ROC) analysis revealed that S-SDQ discriminated between the SMI and the MCI groups. CONCLUSION: S-SDQ may be a solution to the problem of contamination by education and age which affect traditional cognitive screening instruments like K-MMSE, and it may be a useful tool for screening MCI.

Background: There is a correlation between the severe fever with thrombocytopenia syndrome (SFTS) viral load and disease severity; however, measurement of viral load is difficult in general laboratory and it takes time to obtain a viral load value. Here, the laboratory parameters for predicting the dynamic changes in SFTS viral load were identified.In addition, we tried to evaluate a specific time point for the early determination of clinical deterioration using dynamic change of laboratory parameters. Materials and Methods: This observational study included SFTS patients in Korea (2013 - 2020). Cross-correlation analysis at lagged values was used to determine the temporal correlation between the SFTS viral loads and time-series variables. Fifty-eight SFTS patients were included in the non-severe group (NSG) and 11 in the severe group (SG). Results: In the cross-sectional analyses, 10 parameters -white blood cell, absolute neutrophil cell, lymphocyte, platelet, activated partial thromboplastin time (aPTT), C-reactive protein, aspartate aminotransferase (AST), alanine transaminase (ALT), lactate dehydrogenase (LDH), and creatine phosphokinase (CPK)- were assessed within 30 days from the onset of symptoms; they exhibited three different correlation patterns: (1) positive, (2) positive with a time lag, and (3) negative. A prediction score system was developed for predicting SFTS fatality based on age and six laboratory variables -platelet, aPTT, AST, ALT, LDH, and CPKin 5 days after the onset of symptoms; this scoring system had 87.5% sensitivity and 86.0% specificity (95% confidence interval: 0.831 - 1.00, P <0.001). Conclusion Three types of correlation patterns between the dynamic changes in SFTS viral load and laboratory parameters were identified. The dynamic changes in the viral load could be predicted using the dynamic changes in these variables, which can be particularly helpful in clinical settings where viral load tests cannot be performed. Also, the proposed scoring system could provide timely treatment to critical patients by rapidly assessing their clinical course.

OBJECTIVE: This study examined the efficacy and safety of memantine-an uncompetitive N-methyl-D-aspartate (NMDA) receptor antagonist-in the treatment of moderate-to-severe dementia. METHODS: Forty-four patients with moderate-to-severe dementia received 20 mg of memantine daily for 24 weeks. The primary efficacy variable was measured by the Korean version of Severe Impairment Battery(K-SIB), and the secondary efficacy variables were measured using the Seoul-Activites of Daily Living(S-ADL) and Neuropsychiatric Inventory-Questionnaire(NPI-Q). Neuropsychological assessments were administrated at baseline, 12 weeks, and 24 weeks. Safety parameters were monitored. RESULTS: Of 44 patients recruited, 30 completed the study and 14 dropped out. Memantine-treated patients showed a therapeutic benefit in all efficacy variables ; the K-SIB, S-ADL, and NPI-Q total scores were not significantly different from baseline either at the endpoint(in the analysis of intention-to-treat, with the last observation carried forward, ITT-LOCF) or at week 24(in the analysis of observed cases, OC). The response rates, when "response" was defined as improved or unchanged in the K-SIB or the S-ADL scores, were 43.3 and 50%, respectively(in the analysis of OC). The responders showed significant improvement in the cognitive subdomain of memory function, praxis, visuospatial ability, and orienting to name. Memantine was shown to be tolerable and safe. CONCLUSIONS: Memantine treatment reduced or delayed clinical deterioration in cognition, function, and behavior in patients with moderate-to-severe dementia.
