목적: 선천면역장애 환자들은 감염에 취약할 뿐만 아니라, 면역이 정상인 사람들에 비해 암 발생률도 높은 것으로 알려져 있다. 본 연구는 단일 기관에서 추적 중인 선천면역장애 환자들에서의 암 발생을 조사하여 보고자 하였다. 방법: 1994년 11월부터 2023년 9월까지 삼성서울병원에서 선천면역장애 진단 하에 추적하는 환자를 대상으로 후향적으로 의무기록을 리뷰하였다. 선천면역장애 환자 중에서 암으로 진단된 환자를 확인하였다. 결과: 총 194명의 선천면역장애 환자 중, 7명(3.6%)의 환자에서 암이 진단되었다. 5명의 환자가 림프종으로 진단받았으며 그 중 4명의 환자는 Epstein-Barr 바이러스 연관 림프종이었다. 나머지 암은 위암과 다발 골수종이었다. 암 진단 당시 나이는 중앙값 18세 (범위, 1세-75세)였다. 암이 발생한 환자들의 면역결핍 질환은 X-linked lymphoproliferative disorder-1 (XLP-1) 3명, activated phosphoinositide 3-kinase delta disease (APDS) 2명, cytotoxic T-lymphocyte antigen 4 (CTLA-4) haplo-insufficiency 2명이었다. 개별 질환별로 분석하였을 때, XLP-1 환자의 75.0%, APDS 환자의 40.0%, CTLA-4 환자의 50.0%에서 암이 발생하였다. XLP-1 환자는 APDS 및 CTLA-4 haplo-insufficiency 환자에 비해 더 이른 나이에 암이 발생하였다 (중앙연령 5세, P<0.001). 한 명은 조혈모세포 이식 치료 중 사망하였다. 결론: 국내 단일 기관에서 진료받는 선천면역장애 환자들의 3.6%에서 암이 발생하였다. 선천면역장애 환자들을 진료하는 의료진들은 이들 환자에서 감염이나 염증 등의 문제외에도 암 발생의 가능성, 특히 Epstein-Barr 바이러스 감염과 연관된 암의 비중이 높은 것에 대한 인식을 갖는 것이 중요하다 Purpose: Cancer incidence is known to be higher in patients with inborn errors of immunity (IEI) compared to the general population in addition to traditionally well-known infection susceptibility. We aimed to investigate cancer occurrence in patients with IEI in a single center. Methods: Medical records of IEI patients treated at Samsung Medical Center, Seoul, Korea were retrospectively reviewed from November 1994 to September 2023. Patients with IEI and cancer were identified. Results: Among 194 patients with IEI, seven patients (3.6%) were diagnosed with cancer. Five cases were lymphomas, 4 of which were Epstein-Barr virus (EBV)-associated lymphomas. The remaining cases included gastric cancer and multiple myeloma. The median age at cancer diagnosis was 18 years (range, 1-75 years). Among patients with cancer, underlying IEIs included X-linked lymphoproliferative disease-1 (XLP-1, n=3), activated phosphoinositide 3-kinase delta syndrome (APDS, n=2), and cytotoxic T-lymphocyte antigen 4 (CTLA-4) haplo-insufficiency (n=2). Seventy-five percent (3/4) of XLP-1 patients, 40.0% (2/5) of APDS patients, and 50.0% (2/4) of CTLA-4 haplo-insufficiency patients developed cancer. Patients with XLP-1 developed cancer at earlier age (median age 5 years) compared to those with APDS and CTLA-4 (P<0.001). One patient with APDS died during hematopoietic cell transplantation. Conclusions: Cancer occurred in 3.6% of IEI patients at a single center in Korea. In addition to infectious complications and inflammation, physicians caring for IEI patients should be aware of the potential risk of cancer, especially in association with EBV infection

Doo Ri Kim,DongSub Kim,SangJoon Choi,Yeon-Lim Suh,유소영,Mi Jin Kim,최연호,김예진 대한소아소화기영양학회 2020 Pediatric gastroenterology, hepatology & nutrition Vol.23 No.3

The musculoskeletal system can be involved as an extra-intestinal manifestation of inflammatory bowel disease. Among these, myositis in ulcerative colitis (UC) is very rare. A 14-year-old girl was admitted due to severe shoulder tenderness. She had complained of left jaw pain and swelling for the past 10 days. Inflammatory markers were elevated with no evidence of infectious etiology. Myositis was suspected by shoulder magnetic resonance imaging. Three days after admission, she developed hematochezia. Muscle biopsy and colonoscopy was performed due to worsening left mandibular area pain and persistent hematochezia. Colonoscopy showed consistent findings with UC. She was finally diagnosed with UC with myositis as an extra-intestinal manifestation. She showed a dramatic response to UC treatment. Gastrointestinal symptoms were well-controlled. After 14 months, UC symptoms and muscle pain were aggravated, which were relieved after steroid and cyclosporin treatment. We report a unique case of UC initially presented with myositis, preceding gastrointestinal symptoms.

목적: 리노바이러스의 감염은 하기도 감염을 일으키기도 한다. 본 연구에서는 리노바이러스에 의한 중증 하기도 감염을 보이는 소아환자의 특성을 알아보고자 하였다. 방법: 2016년부터 2020년까지 삼성서울병원 소아청소년과에 리노바이러스 하기도감염으로 입원한 환자의 의무기록을 후향적으로 분석하였다. 입원 시 연령이 생후90일 이상, 5세 미만인 소아 환자를 대상으로 하였다. 다른 호흡기 병원체와의 동시 감염이 확인된 환자는 제외하였다. 리노바이러스에 의한 중증 하기도감염은 고유량 산소요법 치료가 필요한 경우, 기계 호흡이 필요한 경우 또는 중환자실 입원하는 경우로 정의하였다. 결과: 해당 기간 동안 총 115건의 리노바이러스 하기도 감염 입원이 확인되었다. 연령 중앙값은 17개월 (범위, 3-56개월) 이었으며, 입원 일수 중앙값은 4일 (범위, 2-31일) 이었다. 115 건 중 18건의 입원 (15.7%)은 중증 리노바이러스 하기도 감염 그룹으로 분류되었다. 중증 경과 그룹 환자의 연령 중앙값은 그렇지 않은 그룹에 비해 연령 중앙값이 낮았다 (9.5개월 vs. 19.0 개월, P=0.001). 18명의 중증 리노바이러스 하기도 감염 그룹 환자 중 11명 (61.1%)는 기저질환을 가지고 있었으며, 만성 폐질환이 가장 많은 비율을 차지하였다 (63.6%). 여섯 명의 환자는 (33.3%) 기계 호흡을 필요로 하였다. 일곱 명의 기저질환이 없는 환자도 중증 리노바이러스 하기도 감염 그룹에 포함되어 있었다. 이들 일곱 명의 환자 중 네 명은 추후에 천식으로 진단되었다. 115건의 입원을 기저질환이 없는 환자군 (n=60)과 기저질환이 있는 환자군 (n=55)으로 나누어 분석하였을 때, 리노바이러스에 의한 중증 하기도 감염을 보이는 비율은 각각 11.7% 와 20.0%였다 (P=0.219). 결론: 리노바이러스 감염은 중증 하기도감염의 원인이 될 수 있으며, 기저질환자 뿐 아니라 건강한 소아에서도 중증 하기도감염을 일으킬 수 있다 Purpose: Human rhinovirus (HRV) infections can result in lower respiratory tract infections (LRTIs). We aimed to investigate the characteristics of severe HRV LRTI in young children. Methods: Medical records were reviewed retrospectively in patients who were hospitalized for HRV LRTIs from 2016 to 2020 at the Samsung Medical Center in Seoul, Korea. Patients aged 90 days or older and younger than 5 years were included. Patients with co-infections with other respiratory pathogens were excluded. Severe HRV LRTI was defined as the following: the need for high-flow oxygenation, mechanical ventilation, or intensive care unit admission. Results: A total of 115 cases were identified. The median age was 17 months (range, 3-56 months) and the median hospital days were 4 days (range, 2-31 days). Of the 115 cases, 18 patients (15.7%) developed severe HRV LRTI. The median age was younger in the severe group compared to the non-severe group (9.5 months vs. 19.0 months, P=0.001). Of 18 patients with severe HRV LRTI, 11 (61.1%) had underlying diseases - chronic lung diseases accounted for the largest proportion (63.6%). Six patients (33.3%) required mechanical ventilation. Of note, 7 previously healthy children were diagnosed with severe HRV LRTI. Of those 7 children, 4 of them were diagnosed with asthma later. When the 115 cases were divided into previously healthy (n=60) and underlying disease (n=55) groups, severe courses of HRV LRTI were observed in 11.7% and 20.0% of children, respectively (P=0.219). Conclusions: HRV can cause severe LRTI even in previously healthy children as well as in children with comorbidities

Premature constriction of the ductus arteriosus is rare, but it can occur during fetal life idiopathically or secondaryto medications or structural lesions. Premature constriction of the ductus arteriosus can lead to progressive rightheart dysfunction, heart failure, subsequent hydrops fetalis, and even fetal death. Herein, we describe a case offetal ductus arteriosus constriction of unknown etiology with a severely enlarged and hypertrophied right ventricle,which resolved dramatically soon after birth.

Terpyridine-based organic-inorganic hybrid nanofiber and its application as an adsorbent for protein.

Bae, Doo Ri,Cho, Eun Jin,Kang, Jeong Ku,Jung, Jong Hwa American Scientific Publishers 2010 Journal of nanoscience and nanotechnology Vol.10 No.8

<P>A terpyridine-based organic-inorganic hybrid amphiphile possessing a triethoxylsilane moiety was synthesized and following its self-assembly in the presence of Cu2+ ion, its binding ability of histidine and His-tag proteins was observed by UV-VIS spectroscopy, Circular dichroism spectroscopy and confocal fluorescence microscopy. The self-assembled 1 in the absence and the presence Cu2+ ion revealed a helical fiber structure, and the self-assembled 1 formed a 1:1 complex with Cu2+ ion. Histidine bound to the self-assembled 1-Cu2+ ion, but more interestingly, His-tag protein was selectively bound to the surface of the self-assembled 1-Cu2+ nanofiber. The finding indicates that the self-assembled 1-Cu2+ nanofiber selectively recognized the His-tag protein.</P>

Fast Microchip Electrophoresis Using Field Strength Gradients for Single Nucleotide Polymorphism Identification of Cattle Breeds

Oh, Doo-Ri,Cheong, Il-Cheong,Lee, Hee-Gu,Eo, Seong-Kug,Kang, Seong-Ho Korean Chemical Society 2010 Bulletin of the Korean Chemical Society Vol.31 No.7

A microchip electrophoresis (ME) method was developed using a programmed field strength gradients (PFSG) for the single nucleotide polymorphism (SNP) based fast identification of cattle breeds. Four different Korean cattle (Hanwoo) and Holstein SNP markers amplified by allele-specific polymerase chain reaction were separated in a glass microchip filled with 0.5% poly(ethyleneoxide) ($M_r$ = 8 000 000) by PFSG as follows: 750 V/cm for 0 - 14 s, 166.7 V/cm for 14 - 31 s, 83.3 V/cm for 31 - 46 s, and 750 V/cm for 46 - 100 s. The cattle breeds were clearly distinguished within 45 s. The ME-PFSG method was 7 times and 5 times faster than the constant electric field ME method and the capillary electrophoresis- PFSG method, respectively, with a high resolving power ($R_s$ = 5.05 - 9.98). The proposed methodology could be a powerful tool for the fast and simultaneous determination of SNP markers for various cattle breeds with high accuracy.

Controlled Assembly of Gold Nanoprism and Hexagonal Nanoplate Films for Surface Enhanced Raman Scattering

Lee, Doo-Ri,Hong, Soon-Chang,Park, Sung-Ho Korean Chemical Society 2011 Bulletin of the Korean Chemical Society Vol.32 No.10

This paper reports a methodology for preparing close-packed two dimensional gold nanoprism films and hexagonal nanoplate films at a hexane/water interface. By controlling the concentration of linker molecules in the hexane layer and the temperature of the colloid solution, highly ordered close-packed nanoplate arrays can be fabricated. These films were investigated to compare their corresponding surface enhanced Raman scattering (SERS) efficiencies. It was demonstrated that the Au nanoprism films resulted in a stronger SERS enhancement than the Au hexagonal nanoplate films. The difference in the SERS enhancement is attributed to the film array difference, demonstrating that Au nanoprism films have a higher line contact density than their Au hexagonal analogues.

Low-ppm-Level colorimetric acid detection using gold nanoparticles with electro-steric stabilization.

Bae, Doo Ri,Lee, You-Jin,Lee, Sung Woo,Han, Young-Kyu,Yoon, Jae-Sik,Lee, Ji-Hyun,Lee, Sang-Gil,Chang, Ki Soo,Yi, Gi-Ra,Lee, Gaehang American Scientific Publishers 2014 Journal of nanoscience and nanotechnology Vol.14 No.12

<P>Electro-sterically stabilized gold suspensions were employed in a colorimetric system for the detection of strong acid in water. Using oleyamine and oleic acid as steric stabilizer in 1,2-dichlorobenzene, hydrophobic gold nanoparticles were first synthesized by a reduction reaction of gold salts and were then transferred into water with a cationic surfactant. When the hydrochlo- ric acid solution higher than critical concentration was injected, particles were quickly aggregated and precipitated, creating a clear solution from the colored suspension. The particles were stable against chemical etching by corrosive ion such as chloride. Critical concentration was dependent of the size and concentration of the particles. The minimum concentration of dramatic color change was at 5 ppm level of hydrochloric acid, in which the largest colloidal gold nanoparticles (54 nm) were used. Furthermore, because of their steric repulsive soft layer on particles, particles could be reused for further detection experiments after regeneration by the simple pH-neutralization and washing process.</P>
