이건송,이미정,유지숙,장영표,임인수,노의정,손재성,정은희,홍기배,박우성,김재경 대한소아감염학회 2009 Pediatric Infection and Vaccine Vol.16 No.2

Purpose : A number of countries have experienced an increase in pertussis during the past decade. In particular, there has been an increase in the incidence rate among adolescents and adults. To learn more about the current epidemiology of pertussis, we studied the prevalence and clinical characteristics of pertussis in children in Cheonan, South Korea. Methods : We collected nasopharyngeal aspirates of 118 patients who were treated for respiratory symptoms at Dankook Univeristy Hospital between March 2008 and September 2009. We performed multiplex PCR for detection of Bordetella pertussis in those aspirates. Results : Of the 118 patients, 10 (8%) were positive by PCR for B. pertussis. Six episodes occurred during the period July to September 2009. Nine of the 10 patients were less than 3 months old. Seven of them had not received DTaP vaccine. The mean duration of coughing before diagnosis was 10.9±5.2 days. Ten patients (100%) had paroxysmal cough and 8 (80%) had post-tussive vomiting. Only one patient had fever. One who had complications that include pneumonia, atelectasis and pneumomediastinum developed an absolute increase in leukocyte count (84,400/㎣). There was a statistically significant relation between vaccine being received and development of complications (P =0.033). Conclusion : We suspect that there was an epidemic of pertussis between July and September 2009. Further investigation by a pediatric or nationwide surveillance system is needed to monitor the changing epidemiology for pertussis.

이건송,박윤준,Lee, Kun-Song,Park, Yun-Joon 대한소아소화기영양학회 2009 Pediatric gastroenterology, hepatology & nutrition Vol.12 No.2

목 적: 저자들은 단일 병원에서 발생한 장중첩증의 환아들 중 재발성 장중첩증의 특성 및 예후 그리고 병적 선두의 유무 및 연관성에 대해 알아보고자 하였다. 방 법: 1994년 5월부터 2009년 6월까지 장중첩증으로 단국대학교병원 소아청소년과 및 소아외과에 입원하였던 590명의 환자 중 2회 이상의 장중첩증이 발생한 54명의 환아와 비수술적 정복술에 실패하여 수술을 시행하고 영상의학적 검사에서 병적 선두가 의심되었던 90명 총 144명을 대상으로 하였다. 144명의 의무기록지를 후향적으로 분석하여 재발성 장중첩증이 있었던 54명의 특성(재발률, 재발 횟수, 첫 재발까지의 기간, 정복술 각각의 재발률)과 병적 선두의 종류, 선두의 위치, 재발의 유무, 진단 방법 등에 대하여 알아보았다. 예후는 3회 이상의 장중첩증이 있었고, 2009년 7월까지 전화방문을 통해 추적관찰이 가능하였던 17명을 대상으로 하였다. 통계적 분석은 Pearson 선형상관분석, Fisher's exact test 그리고 Mann-Whitney 검정을 사용하였다. p값이 0.05 미만인 경우를 통계적으로 유의하다고 판정하였다. 결 과: 중첩증의 재발률은 총 590명 중 54명(9.2%)이었다. 54명 중 남아 37명(68.5%), 여아 17명(34.2%)으로 남아에서 2.1배 더 많았다. 초기 중첩증 시 평균 연령은 11.7${\pm}$9.2개월(2~38)이었다. 재발의 빈도는 1회가 35명(64.8%), 2회 10명(18.5%), 3회 3명(5.6%), 4회 3명(5.6%), 5회 1명(1.9%), 6회 1명, 7회 1명이었다. 첫 재발까지의 기간은 평균 130${\pm}$175일(12시간~3년)이었다. 재발의 빈도와 처음 재발사이 기간과는 상관관계가 없었다(r=.0.064, p=0.643). 공기 정복술은 118회 시행 후 재발은 77예(65.2%), 바륨 정복술은 21회 시행 후 14예(66.7%), 도수 정복술은 9회 시행 후 3예(33.3%)로 재발률은 바륨 정복술이 가장 높았으나 통계적 유의성은 없었다(p=0.131). 병적 선두는 전체 590명 중 18명 (3.0%)에서 관찰되었고, 재발성 장중첩증이 있었던 54명의 환자 중에서는 7명(12.9%) 있었다. 병적 선두로는 림프양 증식증이 13예(72.2%), Meckel 게실 2예(11.3%), 중복 낭종 1예(5.5%), 소장 용종 1예, 그리고 선근종 1예가 관찰되었다. 다른 유도 병변으로는 맹장과 말단 회장에 선천성 밴드가 4예가 있었다. 재발성 장중첩증이 있었던 54명 중 병적 선두가 있었던 7명에서 중첩증 횟수의 평균은 4.7${\pm}$1.9회로 47명의 2.4${\pm}$0.9회 보다 통계적으로 유의하게 높았다(p=0.023). 3회 이상의 중첩증이 있었고 추적관찰이 가능하였던 17명의 재발의 기간은 평균 17.4${\pm}$19.8개월(2일~72개월)이었다. 수술을 하지 않았던 9명의 재발의 기간은 평균 18.8${\pm}$16.3개월(2일~45개월)이었고 마지막 중첩증 시 평균나이는 32.6${\pm}$16.2개월이었다. 추적관찰 동안 17명 모두 재발은 없었다. 결 론: 병적 선두가 존재하는 환아에서 재발성 중첩증의 빈도가 높으며 3회 이상의 중첩증이 있는 경우는 병적 선두에 대한 조사를 시행하여 제거술을 시행하거나 비수술적 정복술을 시행하며 추적관찰을 할 수 있다. 추후 중첩증의 재발을 막을 수 있는 치료법에 대한 더 많은 연구가 시행되어야 할 것으로 생각한다. Purpose: Intussusception is the most common cause of intestinal obstruction in young children. Although intussusceptions are easily treated, some intussusceptions with or without a pathologic lead point (PLP) often recur. In this study, we analyzed the clinical characteristics and prognosis of recurrent intussusceptions (RI), the frequency of the PLP, and correlation between RI with PLP. Methods: The medical records of 144 patients, among 590 patients with intussusceptions who had been admitted to the Department of Pediatrics and Pediatric Surgery of Dankook University Hospital between May 1994 and June 2009 were reviewed retrospectively. Results: The overall recurrence rate of intussusceptions in this study was 9.2%. The mean interval between the initial occurrence and the first recurrent attack was 130${\pm}$175 days (range, 12 hours to 3 years). There was no statistically significant difference in the recurrence rate among patients who underwent air, barium, and manual reduction (p=0.131). Eighty-seven cases (92.6%) of RI had a successful reduction by the use of non-operative techniques. A PLP was present in 18 patients (3.0%). The most common PLP was intestinal lymphoid hyperplasia, followed by Meckel's diverticulum, duplication cyst, intestinal polyp, and adenomyoma. The mean number of intussusceptions was 4.7${\pm}$1.9 in 7 patients with PLP, which was significantly higher than (2.4${\pm}$0.9) patients without a PLP (p=0.023). The mean duration of recurrences was 17.4${\pm}$19.8 months (range, 2 days to 72 months). Conclusion: A careful search for a PLP should be performed to prevent recurrence of intussusception, especially when intussusception has recurred more than three times.

이건송,양혜란,고재성,서정기,이혜승,Lee, Kun-Song,Yang, Hye-Ran,Ko, Jae-Sung,Seo, Jeong-Kee,Lee, Hye-Seung 대한소아소화기영양학회 2008 Pediatric gastroenterology, hepatology & nutrition Vol.11 No.2

만성 복통을 주소로 내원한 12세 여아에서 내시경 소견상 결절성 위염과 조직 검사상 H. pylori 감염을 확인 하였으며, 병리 소견 및 면역조직화학 검사상 위 MALT 림프종으로 진단되어, H. pylori 제균 치료 후 결절성 위염의 호전과 위 MALT 림프종의 완전한 관해를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. Most cases of mucosa-associated lymphoid tissue (MALT) lymphoma occur in adults. MALT lymphoma is very rare in children. Helicobacter pylori (H. pylori) infection is known to be an important etiologic factor predisposing to the development of gastric MALT lymphoma. A 12-year-old girl was admitted because of intermittent abdominal pain occurring over the preceding 2 years. Nodular gastritis of the stomach was demonstrated on endoscopy. H. pylori infection was confirmed using the rapid urease test and histopathology. Histopathological examination of gastric biopsy specimens revealed lymphoepithelial lesions pathognomonic of MALT lymphoma, and immunohistochemical staining for CD20 was diffusely positive. Therefore, the patient was diagnosed with gastric MALT lymphoma. Clinical manifestations and histopathologic findings compatible with MALT lymphoma improved with the eradication of H. pylori infection. We report a case of primary gastric MALT lymphoma in a child, associated with H. pylori infection and presenting as nodular gastritis.

신생아에서 제대 동맥혈 Isoprostane(8-iso-PGF₂_α) 농도에 관한 연구

이건송,지윤희,장영표,Lee, Kun Song,Ji, Yoon Hee,Chang, Young Pyo 대한소아청소년과학회 2003 Clinical and Experimental Pediatrics (CEP) Vol.46 No.9

목 적 : 지질 과산화의 주요 지표 중에 하나인 isoprostane($8-iso-PGF_{2{\alpha}}$)을 제대 동맥혈에서 측정하여 신생아에 산화손상을 유발 할 수 있는 주산기 위험인자 및 신생아기 주요 질환과의 관계를 규명하여, 제대 동맥혈 isoprostane이 신생아에서 산화손상의 지표로 사용할 수 있는지를 알아보고자 하였다. 방 법 : 2000년 6월부터 2001년 3월까지 단국대학교병원 신생아 중환자실 및 신생아실에 입원하였던 미숙아 33명과 만삭아 28명을 대상으로 제대 동맥혈에서 혈청을 분리하여 $-70^{\circ}C$에서 냉동 보관 후 isoprostane($8-iso-PGF_{2{\alpha}}$)과 malondialdehyde(MDA)를 측정하였다. 측정된 isoprostane과 MDA 농도를 미숙아와 만삭아에서 각각 비교하였고, 주산기-신생아기 위험인자와 주요 합병증과의 상관관계를 알아보았다. 결 과 : 평균 출생 체중은 미숙아 $1,771{\pm}445gm$, 만삭아 $3,200{\pm}567gm$이었고, 평균 재태 연령은 미숙아 $31.5{\pm}2.0$주, 만삭아 $39.0{\pm}2.0$주였다. 제대 동맥혈 isoprostane 농도는 미숙아 $704.7{\pm}635.6pg/mL$, 만삭아 $423.9{\pm}306.5pg/mL$로 미숙아에서 통계적으로 의미있게 높았으며(P<0.05), MDA도 미숙아 $44.0{\pm}22.9{\mu}M/L$, 만삭아 $28.2{\pm}10.7{\mu}M/L$로 미숙아에서 의미있게 높았다(P<0.05). 미숙아의 경우 isoprostane은 출생 후 24시간에 $478.6{\pm}580.6pg/mL$로 유의하게 감소하였다(P<0.05). 미숙아 제대 동맥혈 isoprostane은 둔위 분만, 양수 과소증, 신생아 가사와 통계적으로 유의한 상관관계가 있었고(P<0.05), 만삭아 제대 동맥혈 isoprostane은 임신성 고혈압과 유의한 상관관계를 보였다(P<0.05). 그러나 미숙아 제대 동맥혈 isoprostane은 신생아기의 주요 합병증과는 상관관계가 없었다. 결 론 : 미숙아에서 제대 동맥혈 isoprostane 농도는 만삭아에 비하여 높고, 일부 주산기-신생아기 위험인자와 연관이 있어서, 주산기-신생아기에 산화손상과 관련된 주요 지표 중에 하나로 사용될 가능성이 있음을 추측하였다. Purpose : We measured the umbilical cord arterial concentrations of isoprostane($8-iso-PGF_{2{\alpha}}$) and intended to decide whether the umbilical cord arterial concentrations of isoprostane could be used as a useful parameter for lipid peroxidation in newborn infants. Methods : The isoprostane and malondialdehyde(MDA) concentrations of the umbilical cord were measured by enzyme immunoassay and TBARS(thiobarbituric acid reactive substance) assay in 33 preterm and 28 term infants, respectively. The concentrations of isoprostane and MDA were compared between preterm infants and term infants, and were analysed for association with perinatal risk factors and neonatal complications. Results : Umbilical cord arterial concentrations of isoprostane were $704.7{\pm}635.6pg/mL$ and $421.9{\pm}306.5pg/mL$ in preterm and term infants, respectively. Umbilical cord arterial concentrations of MDA were $44.0{\pm}22.9{\mu}M/L$ and $26.2{\pm}10.7{\mu}M/L$ in preterm and term infants, respectively. Umbilical cord arterial concentrations of isoprostane and MDA in preterm infants were significantly higher than those in term infants(P<0.05). The umbilical cord arterial concentrations of isoprostane were significantly associated with perinatal risk factors such as fetal distress, oligohydramnios, and breech delivery in preterm infants and pregnancy-induced hypertension in term infants(P<0.05). Conclusion : Umbilical cord arterial concentrations of isoprostane in preterm infants were higher than those in term infants, and those are significantly associated with some perinatal risk factors.

How to Do in Persistent Diarrhea of Children?: Concepts and Treatments of Chronic Diarrhea

이건송,Dong Soo Kang,유지숙,장영표,Woo Sung Park 대한소아소화기영양학회 2012 Pediatric gastroenterology, hepatology & nutrition Vol.15 No.4

Chronic diarrhea is defined as passing watery stools that lasts for more than 2 weeks. Persistent diarrhea belongs to chronic diarrhea and is a chronic episode of diarrhea of infectious etiology. The etiology of chronic diarrhea is varied. It is important to consider the child’s age and clinical manifestations with alarm signals for an application of proper treatments to children with chronic diarrhea. Vicious cycle is present in chronic diarrhea and nutritional rehabilitation can break the vicious cycle of chronic diarrhea and is one of the main one thing among treatments. We should know the exact concept of chronic diarrhea and provide appropriate treatments according to etiologies of chronic diarrhea.

Preoperative Diagnosis of Congenital Esophageal Stenosis Caused by Tracheobronchial Remnants Using Miniprobe Endoscopic Ultrasonography in a Child

이건송 대한소아소화기영양학회 2012 Pediatric gastroenterology, hepatology & nutrition Vol.15 No.1

Congenital esophageal stenosis (CES) can be classified into three types based on the etiology of stenosis: tracheobronchial remnants (TBRs), fibromuscular hypertrophy (FMH), and membranous diaphragm (MD). It is important to make a differential diagnosis because the therapeutic plan for CES is determined by its etiology. Most cases of FMH and MD can be managed with balloon dilatation, whereas cases of TBRs require resection and anastomosis. Thus, the preoperative distinction of TBRs is critical. Recently miniprobe endoscopic ultrasonography (EUS) with a maximum diameter of 2.5 mm has been useful for distinguishing TBRs from FMH in pediatric patients with CES. EUS shows hyperechoic lesions indicating TBR cartilage. Miniprobe EUS is recommended for choosing the correct therapeutic method for CES. We report a case of CES due to TBRs in which a preoperative diagnosis was made in a child using miniprobe EUS without any difficulties.

Nationwide Multicenter Study of Eosinophilic Esophagitis in Korean Children

이건송,최병호,Ben Kang,Seung Kim,Jae Young Kim,Jung Ok Shim,이유민,Eun Hye Lee,Hyo-Jeong Jang,Eell Ryoo,Hye Ran Yang 대한소아소화기영양학회 2020 Pediatric gastroenterology, hepatology & nutrition Vol.23 No.3

Purpose: In East Asian countries, there are only a few epidemiologic studies of eosinophilic esophagitis (EoE) and no studies in children. We investigated the incidence and compared the clinical characteristics of EoE and eosinophilic gastroenteritis involving the esophagus (EGEIE) in Korean children. Methods: A total of 910 children, who had symptoms of esophageal dysfunction, from 10 hospitals in Korea were included. EoE was diagnosed according to diagnostic guidelines and EGEIE was diagnosed when there were >15 eosinophils in the esophagus per high power field (HPF) and >20 eosinophils per HPF deposited in the stomach and duodenum with abnormal endoscopic findings. Results: Of the 910 subjects, 14 (1.5%) were diagnosed with EoE and 12 (1.3%) were diagnosed with EGEIE. Vomiting was the most common symptom in 57.1% and 66.7% of patients with EoE and EGEIE, respectively. Only diarrhea was significantly different between EoE and EGEIE (p=0.033). In total, 61.5% of patients had allergic diseases. Exudates were the most common endoscopic findings in EoE and there were no esophageal strictures in both groups. The median age of patients with normal endoscopic findings was significantly younger at 3.2 years, compared to the median age of 11.1 years in those with abnormal endoscopic findings (p=0.004). Conclusion: The incidence of EoE in Korean children was lower than that of Western countries, while the incidence of EGEIE was similar to EoE. There were no clinical differences except for diarrhea and no differences in endoscopic findings between EoE and EGEIE.
