( Gahee Kim ),( Junbum Lee ),( Sangho Lee ),( Jeong-hyun Choi ) 경희대학교 경희의료원 2022 慶熙醫學 Vol.37 No.1

Sugammadex induced anaphylactic reaction is very urgent event as it is usually not anticipated in the advance. The incidence of anaphylactic reaction due to sugammadex is rare, 0.0039% to 0.3%, but it can occur even if there is no previous allergy history, and it often occurs after extubation, so immediate diagnosis and treatment are essential. This report presents a 70-year-old woman who had no previous exposure to sugammadex and allergy history and scheduled to undergo posterior lumbar interbody fusion L4-S1 to treat lumbosacral spondylolisthesis. Anesthesia via propofol, inhalational gas, remifentanil and rocuronium was used. The operation under general anesthesia went well without any problems The patient was administered sugammadex to reversal neuromuscular block, and delivered to post-anesthesia care unit (PACU). After arrival at PACU, she had anaphylactic reaction and received appropriate treatment including epinephrine. She discharged without any complications 6 weeks days after the surgery.

Lee, Dong Bok,Kim, Kwang-Joong,Yoo, Gahee,Park, Sung,Lee, Jae Chun American Scientific Publishers 2015 Journal of Nanoscience and Nanotechnology Vol.15 No.7

<P>The effect of adding Al2O3 nano-filler (5 and 10 vol%) to two different alkali/alkaline-earth borosilicate glass sealants, particularly on the viscosity and electrical characteristics of the glass composite sealants, was investigated to improve the cyclic sealing performance. The effects of the filler and base glass composition on the viscosities, electrical conductivities, and phase transformations of the sealants were investigated. The glass viscosity was decreased by replacing 20 mol% SrO with alkali and zirconium oxide in a base alkaline-earth glass. Alumina filler increased the high-temperature electrical conductivities, as well as the viscosities, of the heat-treated glass composite sealants. The replacement of 20 mol% SrO with alkali and zirconium oxide in the base alkaline-earth glass decreased the electrical conductivity of the heat-treated glass containing Al2O3 nano-filler.</P>

Characterization of Ceftriaxone-Resistant Haemophilus influenzae Among Korean Children

Lee Sanghoon,Kim Gahee,Kim Jung Hwa,Kim Mi-Na,Lee Jina 대한의학회 2024 Journal of Korean medical science Vol.39 No.15

Background: Haemophilus influenzae is a frequently encountered pathogen responsible for respiratory tract infections in children. Following the detection of ceftriaxone-resistant H. influenzae at our institution, we aimed to investigate the resistance mechanisms of ceftriaxone in H. influenzae, with a particular focus on alterations in penicillin-binding protein 3 (PBP3) and β-lactamase production. Methods: Among H. influenzae isolates collected at Asan Medical Center Children’s Hospital from March 2014 to April 2019, ceftriaxone-resistant strains by the disk-diffusion test were included. Ceftriaxone minimum inhibitory concentrations (MICs) were determined using the E-test according to the European Committee on Antimicrobial Susceptibility Testing (EUCAST) guidelines. The presence of β-lactamase was assessed through cefinase test and TEM-1/ROB-1 polymerase chain reaction (PCR). PBP3 alterations were explored via ftsI gene sequencing. Results: Out of the 68 collected strains, 21 exhibited resistance to ceftriaxone in disk diffusion tests. Two strains were excluded due to failed subculture. Among 19 ceftriaxoneresistant H. influenzae isolates, eighteen were non-typeable H. influenzae, and twelve were positive for TEM-1 PCR. Isolates were classified into groups II (harboring only N526K, n = 3), III (N526K+S385T, n = 2), III+ (S385T+L389F+N526K, n = 11), and III-like+ (S385T+L389F+R517H, n = 3) according to the PBP3 alteration pattern. With a median ceftriaxone MIC of 0.190 mg/L (range, 0.008–0.750), the median ceftriaxone MIC was the highest in group III-like+ (0.250 mg/L), followed by groups III+ (0.190 mg/L), III (0.158 mg/L), and II (0.012 mg/L). All three strains belonging to group II, which did not harbor the S385T substitution, had ceftriaxone MICs of ≤ 0.125 mg/L. Conclusion: The emergence of ceftriaxone-resistant H. influenzae with ceftriaxone MIC values of up to 0.75 mg/L was observed even in children in South Korea, with most associated with S385T and L389F substitutions. The N526K mutation alone does not significantly impact ceftriaxone resistance. Further large-scale studies are essential to investigate changes in antibiotic resistance patterns and factors influencing antibiotic resistance in H. influenzae isolated from pediatric patients in Korea.

Gahee Son,Sohee Oh,Jaehee Lee,Saeromi Jun,Jongbin Kim,Jongsoo Kim,Joonhaeng Lee,Miran Han,Jisun Shin The Korean Dental Society of Anesthsiology 2024 Journal of Dental Anesthesia and Pain Medicine Vol.24 No.3

Background: Patients with autism spectrum disorder (ASD) present challenges in dental treatment cooperation owing to deficits in communication skills and social interaction. Behavioral guidance, sedation, and general anesthesia may be employed to ensure the quality of dental care for individuals with ASD. This study aimed to examine the trends in dental treatment for patients with ASD who visited the Department of Pediatric Dentistry at Dankook University Jukjeon Dental Hospital, an oral health center for the disabled in the Gyeonggi region, over the past 10 years. Methods: This study utilized the order communication system to gather data on sex, age, cooperation level, number of quadrants treated, and administration of sedation or general anesthesia for patients with ASD who visited the Department of Pediatric Dentistry at Dankook University Jukjeon Dental Hospital between January 2013 and December 2022. Results: The total number of patients with ASD increased annually, possibly due to an increase in ASD prevalence and the hospital's designation as a center for disabled oral health. General anesthesia was predominant before 2017, with a shift towards N₂O-O₂ sedation. The most common age group for sedation or general anesthesia was 6-9 years, with a higher prevalence in males than in females. Notably, N₂O-O₂ and midazolam sedation resulted in better cooperation and fewer treated teeth than general anesthesia. Conclusion: This study highlights the evolving trends in dental treatment for individuals with ASD, indicating a shift towards outpatient methods, particularly N₂O-O₂ sedation. The sex distribution aligns with national statistics, emphasizing a higher prevalence of ASD in males than in females. These findings underscore the need for further research to establish evidence-based guidelines for optimal dental care strategies tailored to the unique needs of individuals with ASD.

Coal is spotlighted as a top priority energy resource which will replace oil. Coal gasification can reduce amount of carbon dioxide(CO<SUB>2</SUB>), sulfur oxides(SOx) and nitrogen oxides(NOx). Also, it produces mono dioxide(CO) and Hydrogen(H<SUB>2</SUB>). However, typical-type coal gasification technology is required huge amount of energy at high temperature over 1000℃. Therefore, catalyst(K<SUB>2</SUB>CO<SUB>3</SUB>) is added to decrease operation temperature and reduce amount of energy. In this experiment, Roto ultra clean coal(UCC) and Roto original coal(OC) are used. And coal char is produced for this experiment. The experiment is progressed with 1g of coal char with potassium carbonate(K<SUB>2</SUB>CO<SUB>3</SUB>) under flowed 500ml/m of steam(H<SUB>2</SUB>O) as a reactant and 2000ml/min of nitrogen as carrier gas. With this condition, it is progressed for 1hr under different designated temperature(600, 700, 800℃) and different catalyst conditions. From those experiments, the carbon conversion ratio is calculated and compared the gasification reactivity

( Junbum Lee ),( Gahee Kim ),( Sangho Lee ),( Jeong-hyun Choi ) 경희대학교 경희의료원 2022 慶熙醫學 Vol.37 No.1

Charcot-Marie-Tooth (CMT) disease is a hereditary motor and sensory neuropathy of the peripheral nervous system. The initial presentation is usually foot drop or muscle wasting of the distal part of the leg. The symptom eventually progresses to atrophy of respiratory muscles, vocal cord and diaphragm. CMT patients require special caution during the general anesthesia. CMT disease can cause malignant hyperthermia, respiratory insufficiency and hyperkalemia during anesthesia. This report presents a 50-year-old man who has been diagnosed CMT disease and scheduled to undergo anterior cervical discectomy and fusion to treat cervical spinal stenosis. Propofol and remifentanil were used for the total intravenous anesthesia, and rocuronium was used for muscle relaxant purpose. Several intraoperative monitoring methods were performed to proceed the anesthesia safely, and the patient was discharged without any complications 5 days after the surgery. This case report with comprehensive literature review investigates possible adverse events and special cautions during the general anesthesia of CMT patients, and discusses adequate intraoperative monitoring to avoid such problems.
