Purpose: This study clarified the bacterial pathogens currently causing acute infectious enterocolitis (AIE) in children and evaluated the clinical characteristics and ultrasonographic findings according to the different pathogens. Methods: Medical records regarding age, sex, clinical symptoms, laboratory data, identified enteropathogens, ultrasonographic findings, treatment, and outcome of 34 patients who were diagnosed with AIE via stool examination using multiplex polymerase chain reaction (PCR) or culture, were retrospectively reviewed. Results: Twenty-four patients (70.6%) were male. The mean age of the patients was 8.5±6.2 (range, 1.1-17.1) years. Six bacterial pathogens were isolated: Salmonella species (spp.) (32.4%), Campylobacter spp. (20.6%), verotoxin- producing Escherichia coli (14.7%), Staphylococcus aureus (11.8%), Clostridium difficile (8.8%), and Shigella spp. (2.9%). Abdominal pain occurred in all patients regardless of pathogen. The patients infected with Salmonella were older than those infected with verotoxin-producing E. coli (p<0.05). C-reactive protein levels were higher in patients with Salmonella and Campylobacter infections than in those with verotoxin-producing E. coli infection (p< 0.05), the other clinical and laboratory data were indistinguishable between pathogens. Ultrasonography demonstrated diverse involvement of bowel segments according to pathogen. Wall thickening of both the ileum and the entire colon was the most common lesion site regardless of pathogen. Conclusion: Various bacterial agents cause AIE and the symptoms are diverse symptoms, however, all most children recovered spontaneously. Use of multiplex PCR on stool samples warrants improvement of its sensitivity for diagnosis of enteropathogenic bacteria. Ultrasonographic examination is useful for diagnosis of AIE; it can also detect the disease extent and severity.

Diphtheria-Tetanus-Acellular Pertussis and Inactivated Poliomyelitis Vaccination as a Possible Cause of Bell's Palsy

천베드로,김혜영,이윤진,남상욱,김영미,이경연 대한소아신경학회 2010 대한소아신경학회지 Vol.18 No.2

Bell's palsy is an idiopathic peripheral facial nerve palsy of acute onset. Although some studies have reported cases of Bell's palsy after certain vaccinations, reports of Bell’s palsy in association with diphtheria-tetanus-acellular pertussis (DTaP) and inactivated poliomyelitis vaccination (IPV) have been rare. Here, we report two infants who suffered from Bell’s palsy after immunization with DTaP and IPV and recovered completely without neurologic deficits. 벨 마비(Bell’s palsy)는 급성으로 발생하는 특발성 말초성 안면신경마비로 소아의 가장 흔한 말초성 안면신경마비의 원인 중 하나이다. 과거에도 예방접종과 관련하여 발생한 벨 마비에 대한 보고가 있었으나 디프테리아-파상풍-정제 백일해 항원(DTaP) 혼합 백신 및 불활화 소아마비 사백신(IPV) 접종과 관련된 증례는 드물다. 저자들은 두 명의 영아에서 DTaP 및 IPV 접종 후 발생한 벨 마비를 진단하였고, 특별한 치료를 하지 않고 호전된 증례를 경험하였기에 보고하는 바이다.

천베드로,이형두,김영돈 대한신생아학회 2011 Neonatal medicine Vol.18 No.2

Scimitar syndrome (SS) is a rare congenital anomaly characterized by hypoplasia of the right lung and partially anomalous pulmonary venous drainage to the inferior vena cava. The term scimitar derives from the shadow created by the anomalous pulmonary vein on chest X-ray that closely resembles that of a curved Turkish sword. It rarely presents as an isolated abnormality. Various cardiac and non-cardiac anomalies have been association with SS, such as right lung hypoplasia, dextroposition of the heart, hypoplasia of the right pulmonary artery, systemic arterial blood supply to the right lower lung from the infra-diaphragmatic aorta, and a secundum type of atrial septal defect. However, an imperforate anus has not been reported previously in association with SS. We describe the first case of infantile scimitar syndrome accompanied with an imperforate anus in a newborn who presented with tachypnea and right pulmonary atelectasis. Scimitar증후군은 우측 폐정맥이 하대정맥을 통하여 좌심방이 아닌 우심방으로 연결되는 부분 폐 정맥 환류이상을 보이면서 우측 폐의 발육부전, 우폐동맥의 발육부전 및 폐 분리증 등과 같은 동반 기형을 보이는 매우 드문 심폐기형 가운데 하나이다. 또한 선천성 항문 막힘증은 출생 후 조기에 잘록 창자 창냄술과 같은 적극적인 수술적 치료가 요구되는 항문 직장 기형의하나로 비뇨기계 이상, 척추 이상, 기관지 식도루, 식도 폐쇄증 혹은 심혈관계 이상 등이 동반될 수 있다. 그러나, 부분 폐 정맥 환류 이상의 하나인 scimitar증후군이 항문 막힘증과 함께 동반됨을 보고한 예는 아직까지 국내외적으로 없었다. 이에 저자들은호흡 곤란 및 선천성 편측 폐 발육부전 및 항문 막힘증을 주소로 입원한 신생아에서 진단된 scimitar 증후군 1례를 경험하였기에 보고하는 바이다.

천베드로,공섬김,변신연,박수은,이형두,Chun, Peter,Kong, Seom-Gim,Byun, Shin-Yun,Park, Su-Eun,Lee, Hyung-Du 대한소아청소년과학회 2010 Clinical and Experimental Pediatrics (CEP) Vol.53 No.4

목 적: 신생아 패혈증은 1개월 미만의 신생아 특히 미숙아, 저체중 출생아에서 사망률과 이환률의 중요한 원인이다. 저자는 최근 6년간 단일 신생아중환자실에서 패혈증으로 진단된 환자의 발생빈도, 원인균 및 임상적 특징을 알아보고자 하였다. 방 법: 2003년 1월부터 2008년 12월까지 신생아중환자실에 입원한 환자 중 혈액에서 균이 배양된 175명을 대상으로 하였다. 환자들의 성별, 재태 주수, 출생 시 체중, Apgar 점수, 총 입원기간, 총정맥영양 기간, 중심도관 유무, 기저 질환, 혈액검사 소견, 배양된 균 종류, 합병증, 사망률을 후향적으로 분석하였고 2005년 1월부터 2008년 12월까지 신생아중환자실의 재원환자 일수에 대한 병원감염률도 분석하였다. 결 과: 1) 6년간 패혈증 발생빈도는 4.7%, 1,000명당 46.7명 이었다. 2004년에 가장 높은 패혈증 발생빈도를 보였고 이후 점차 감소하다 2007년부터 다시 증가하는 추세이다. 그람 양성균패혈증이 그람 음성균보다 많았다. 2) 총 175명의 환자 중 남 녀비는 1.2:1 이었고, 그람음성균군에서 재태 주수와 출생체중이 의미있게 더 작았다. Apgar 점수, 총 입원 기간, 총정맥영양 기간, 중심도관 유무는 두 군간에 유의한 차이가 없었다. 3) 기저질환이 있었던 경우는 총 129명(73.7%)이었고, 이 중 심혈관 질환이 가장 많았다. 배양된 균들 중 그람양성균은 MRSA가 50명(28.6%)으로 가장 많았고, 그람음성균은 $Serratia$ $marcescens$가 14명(8.0%)으로 가장 많았다. 4) 혈액검사 소견에서 그람음성균군의 혈소판이 의미있게 더 낮았으며($P$<0.05) 다른 소견은 유의한 차이가 없었다. 5) 합병증은 32명(18.3%)에서 나타났고, 패혈성 쇼크가 16명(50.0%)으로 가장 많았다. 원인균별로 분석했을 때 MRSA 패혈증에서 합병증의 빈도가 가장 높았다. 6) 패혈증으로 사망한 경우는 총 13명(7.4%)으로 그람양성균군의 사망률은 6.5%, 그람음성균군의 사망률은 10.8% 였으며 MRSA에 의한 사망이 가장 많았다. 7) 각 연도별 월별 재원환자일수에 대한 병원감염률을 보면 월별의 차이가 뚜렷하게 나타났다. 결 론: 패혈증으로 진단된 환자의 발생빈도 및 원인균의 분석, 임상적 특징, 합병증과 사망률에 영향을 주는 원인균에 대한 논의는 향후 신생아중환자실의 감염 발생을 감소시키는데 기여할 것으로 생각되고, 이에 대한 더 많은 연구가 필요할 것이다. Purpose : Sepsis is a significant cause of morbidity and mortality in the newborn, particularly in preterm. The objective of this study was to analyze the incidence rate, causative pathogens and clinical features of neonatal sepsis in one neonatal intensive care unit (NICU) for 6 years. Methods : This study was retrospectively performed to review the clinical and laboratory characteristics including sex, gestational age, birth weight, Apgar score, length of hospitalization, length of total parenteral nutrition, presence of central venous catheter, underlying diseases, laboratory findings, microorganisms isolated from blood culture, complications and mortality in 175 patients between January 2003 and December 2008. Results : 1) Sepsis was present in 175 of 3,747 infants for 6 years. There were more gram-positive organisms. 2) The gram-negatives were more prevalent in preterm. There were no significant differences of other clinical features between two groups. 3) Underlying diseases were found in 73.7%, and the most common disease was cardiovascular disease. The most common organisms of gram-positives and gram-negatives were methicillin resistant Staphylococcus aureus (MRSA) and Serratia marcescens. 4) There was statistically significant difference on platelet counts between two groups (P<0.05). 5) Complications were found in 18.3% and septic shock was the most common. MRSA was the most common pathogen in sepsis with complication. 6) The mortality rate was 7.4%. 7) There were differences in monthly blood stream infection/1,000 patient-days. Conclusion : The studies about the factors that can influence neonatal sepsis will contribute to decrease the infection rates in NICUs.

Gastric Hemangioma Treated with Argon Plasma Coagulation in a Newborn Infant

이영아,천베드로,황은하,이연주,김창원,박재홍 대한소아소화기영양학회 2017 Pediatric gastroenterology, hepatology & nutrition Vol.20 No.2

Gastric hemangioma in the neonatal period is a very rare cause of upper gastrointestinal bleeding. We present a case of hemangioma limited to the gastric cavity in a 10-day-old infant. A huge, erythematous mass with bleeding was observed on the lesser curvature side of the upper part of the stomach. Surgical resection was ruled out because the location of the lesion was too close to the gastroesophageal junction. Medical treatment with intravenous H2blockers, octreotide, packed red blood cell infusions, local epinephrine injection at the lesion site, application of hemoclip, and gel-form embolization of the left gastric artery did not significantly alter the transfusion requirement. Hemostasis was achieved with endoscopic argon plasma coagulation (APC). After two sessions of APC, complete removal of the lesion was achieved. APC was a simple, safe and effective tool for hemostasis and the ablation of gastric hemangioma without significant complications.

Accuracy of an Interferon-gamma Release Assay to Detect Active Tuberculosis in Children: A Pilot Study

이영진,박수은,천베드로,위주희 대한소아감염학회 2011 Pediatric Infection and Vaccine Vol.18 No.1

Purpose:Early diagnosis of active tuberculosis (TB) in children is difficult. The widely used tuberculin skin test has low sensitivity and cross reactivity with non-tuberculous mycobacteria or Bacille Calmette-Guérin vaccination. Interferon gamma release assays have been shown good diagnostic accuracy for active in adults. But studies in children were limited. The purpose of this study was to examine the performance of enzyme-linked immunospot assay (ELISpot) as an initial test in the diagnosis of active tuberculosis in children. Methods:In a hospital-based study, we prospectively examined the performance of ELISPot in 33 children suspected of active TB. TB was confirmed bacteriologically or histologically. Results:Among 33 patients, 9 had active tuberculosis. When tested, they all had a positive test result from the ELISpot. The sensitivity and specificity of the assay were 100% (95% CI, 66.4-100%) and 95.8% (95% CI, 78.9-99.9%) respectively. Conclusion:ELISpot might be an useful and improved clinical diagnostic method for the detection of active TB in children.
