목 적 : 동일 병원에서 같은 기준에 의하여 정맥영양을 받는 미숙아들 중에도 간기능 검사 결과는 쓸개즙정체가 있는 경우와 없는 경우, 간효소의 수치만 오르고 쓸개즙정체의 증상이 없는 경우, 쓸개즙정체 및 간효소 수치의 이상이 없는 경우 등 서로 다른 것을 알 수 있다. 저자들은 출생 직후부터 정맥영양을 받은 미숙아 및 극소저출생체중아들을 대상으로 간기능 검사 결과의 양상 및 이에 영향을 미치는 요인을 알아보기 위하여 본 연구를 시행하였다. 방 법 : 2004년 1월 1일부터 2008년 12월 31일까지 가톨릭의대 부천 성모병원 신생아 집중치료실에 입원했던 출생체중 1,500 gm 미만의 미숙아들 중 2주 이상 TPN을 시행한 92명을 대상으로 이들의 의무 기록지를 후향적으로 검토하였다. 정맥영양 시행 2주 이후부터 관찰기간 동안 시행된 대상아 각각의 간기능 검사 전체를 분석하였으며 검사 결과 혈청 직접빌리루빈(direct bilirubin, DB) 2 mg/dL 이상이 측정되었고 담도폐쇄나 쓸개즙정체를 초래할 다른 원인이 배제된 경우 쓸개즙정체 그룹으로, aspartate aminotransferase (AST) 및 alanine aminotransferase (ALT)가 각각 60 IU/L 이상으로 측정되었고 측정시기에 상기의 제외기준을 비롯하여 뚜렷한 간손상의 원인을 알 수 없었던 경우 간세포손상 그룹으로 하였다. DB 2 mg/dL 이상인 쓸개즙정체그룹을 I군, DB 2 mg/dL 미만이나 AST 및 ALT가 각각 60 IU/L 이상인 간효소치 이상군을 II군, 각각에 이상이 없었던 정상군을 III군으로 하였다. 각 대상아들의 출생체중, 재태주령, 분만방법, 당뇨병 및 전자간증 등의 산모질환, 1분 및 5분 아프가 점수, 계면활성제 사용, 장관영양 시작 시기, 정맥영양기간, 적혈구수혈 횟수, 패혈증, 괴사성장염, 만성호흡곤란증, 동맥관개존증 발생 등을 비교하였다. 결 과 : 대상아들 중 쓸개즙정체 그룹이 36명(39.1%), 간세포손상 그룹이 51명(55.4%) 이었으며, I군 36명(39.1%), II군 19명(20.7%), III군 37명(40.2%) 이었다. 쓸개즙정체그룹과 간세포손상 그룹 각각에 대한 T검정 및 교차분석 결과 재태일령, 출생체중, 1분 및 5분 아프가 점수, 정맥영양기간, 적혈구수혈 횟수, 계면활성제 사용, BPD 진단, PDA 진단 유무에서 유의한 상관관계를 보였다(P<0.05). 쓸개즙정체 그룹을 종속변수로 한 다중회귀분석결과 재태주령, 계면활성제 사용, 패혈증, 적혈구수혈 횟수, 동맥관 개존증과의 관계가 유의했다(P<0.05). 결 론 : 정맥영양을 받고 있는 극소저출생체중아의 쓸개즙정체증에 대하여 정맥영양 이외에 출생체중, 재태주령, 1분 및 5분 아프가 점수, 계면활성제사용, 적혈구수혈 횟수, 만성호흡곤란증, 동맥관개존증 등 요인들에 대한 고민이 동반 되어야 할 것으로 생각된다.

This study examined the role of Kupffer cells in altering the hepatic secretory and microsomal function during ischemia and reperfusion (ls/Rp). Rats were subjected to 60 min of hepatic ischemia, followed by 1 and 5 h of reperfusion. Gadolinium chloride ($GdCl_{3}$, 7.5 mg/kg body weight, intravenously) was used to inactivate the Kupffer cells 1 day prior to ischemia. Is/Rp markedly increased the serum aminotransferase level and the extent of lipid peroxidation. $GdCl_{3}$ significantly attenuated these increases. Is/Rp markedly decreased the bile. flow and cholate output, and $GdCl_{3}$ restored their secretion. The cytochrome P450 content was decreased by Is/Rp. However, these decreases were not prevented by $GdCl_{3}$. The aminopyrine N-demethylase activity was decreased by Is/Rp, while the aniline p-hydroxylase activity was increased. $GdCl_{3}$ prevented the increase in the aniline p-hydroxylase activity. Overall, Is/Rp diminishes the hepatic secretory and microsomal drug-metabolizing functions, and Kupffer cells are involved in this hepatobiliary dysfunction.

BACKGROUND/OBJECTIVES: Vitamin D is a pleiotropic hormone that affects various body organ systems. We evaluated the prevalence of a vitamin D deficiency (VDD) and its potential role in the clinical condition of critically ill Korean children. SUBJECTS/METHODS: Patients under 18 years old with a 25(OH) vitamin D measurement on the first day of PICU admission were included from among the children admitted to the pediatric intensive care unit (PICU) of our tertiary children's hospital between October 2017 and January 2019. RESULTS: A total of 172 pediatric patients were enrolled. The mean 25(OH) vitamin D level was 17.5 ± 12.8 ng/mL. There was a 65.1% prevalence of VDD (25(OH) vitamin D level < 20 ng/mL). VDD was associated with age at PICU admission, gastrointestinal/hepatobiliary disorders, International Society of Thrombosis and Hemostasis disseminated intravascular coagulation (ISTH DIC) score, pediatric multiple organ dysfunction syndrome (pMODS) score and with several laboratory test findings including hemoglobin, platelet, C-reactive protein, serum albumin, total bilirubin, prothrombin time, and anti-thrombin III levels. Most of these parameters also showed significant linear correlations with the 25(OH) vitamin D level (P < 0.05). However, no statistically meaningful association was found between VDD and other clinical conditions such as the need for a mechanical ventilator, requirement for vasoactive drugs, duration of the PICU and hospital stays, or PICU mortality. CONCLUSION: There is a high prevalence of VDD in critically ill Korean children. There were significant associations between the 25(OH) vitamin D level and gastrointestinal/hepatobiliary disorders, the pMODS score and with coagulation related factors. Further large-scale studies with more specific subgroup analyses are required to more precisely assess the clinical implications of VDD in critically ill pediatric patients.

소아의 급성 복통은 많은 환자들이 복통의 성격에 대해 적절히 표현하지 못하므로 진단에 어려움을 겪는 경우가 많다. 연령별 급성 복통의 원인들을 잘 숙지하고, 복통의 위치에 따른 진단적 접근을 시행한다. 가장 우선적으로 외과적 복통 여부를 가능한 빠른 시간 내에 감별해야 하며, 다음으로 장 폐쇄, 궤양성 질환, 간담도계 질환 등을 확인해야 한다. 이 때 주의해야 할 것은, 환자의 복통이 완전히 좋아질 때까지 반복적인 문진과 진찰을 게을리 하지 않아야 하는 것이다. 이렇게 함으로써 진단이 지연되거나 피할 수 없는 오진으로 인해 발생하는 환자의 고통을 최소한으로 줄일 수 있을 것이다. 끝으로, 지금까지 금기시 해왔던 급성 복통 환아들에 대한 통증 치료에 대한 인식의 전환이 필요한 때이다.

Obstruction of the extrahepatic bile ducts is the most common cause of conjugated hyperbilirubinemia in early infancy. More than 90% of such obstructive lesions are accounted for by extrahepatic biliary atresia. A rare lesion is obstruction of the common duct by impacted, thickened secretions and bile. Bile plug syndrome is defined as extrahepatic obstruction of the bile ducts by bile sludge in term infants without anatomic abnormalities, congenital chemical defects of bile, or hepatocellular lesions. Obstruction of extrahepatic ducts by plugs of biliary material apperas to be due to the inspissation and precipitation of bile and mucus within the lumen of the ducts. Cholestasis and precipitation of bile develop in association with abnormal composition of bile in cystic fibrosis, hepatocellular damage, prolonged erythroblastic jaundice, altered biliary dynamics with total parenteral nutrition, gut dysfunction, diuretic therapy, exchange transfusions and perinatal hemolysis. In those cases, the term inspissated bile syndrome is used. The clinical and laboratory findings in bile plug syndrome are identical to those observed in biliary atresia and choledochal cyst. The diagnosis can be suspected based on the findings of clinical and laboratory examinations together with hepatobiliary imaging, ultrasonography, radionuclide scan and liver biopsy. We experienced a case of spontaneous resolution of bile plug syndrome in a 4-year-old girl. We report this case with brief review related literatures.

Background: Cancer patients have been disproportionally affected by the coronavirus disease 2019 (COVID-19) pandemic, with high rates of severe outcomes and mortality. Fever is the most common symptom in COVID-19 patients. During the COVID-19 pandemic, physicians may have difficulty in determining the cause of fever (COVID-19, another infection, or cancer fever) in cancer patients. Furthermore, there are no specific guidelines for managing cancer patients with fever during the COVID-19 pandemic. Thus, this study evaluated the clinical characteristics and outcomes of cancer patients with fever during the COVID-19 pandemic. Methods: This study retrospectively reviewed the medical records of 328 cancer patients with COVID-19 symptoms (fever) admitted to five hospitals in Daegu, Korea from January to October 2020. We obtained data on demographics, clinical manifestations, laboratory test results, chest computed tomography images, cancer history, cancer treatment, and outcomes of all enrolled patients from electronic medical records. Results: The most common COVID-19-like symptoms were fever (n=256, 78%). Among 256 patients with fever, only three (1.2%) were diagnosed with COVID-19. Most patients (253, 98.8%) with fever were not diagnosed with COVID-19. The most common solid malignancies were lung cancer (65, 19.8%) and hepatobiliary cancer (61, 18.6%). Twenty patients with fever experienced a delay in receiving cancer treatment. Eighteen patients discontinued active cancer treatment because of fever. Major events during the treatment delay period included death (2.7%), cancer progression (1.5%), and major organ dysfunction (2.7%). Conclusion: Considering that only 0.9% of patients tested for COVID-19 were positive, screening for COVID-19 in cancer patients with fever should be based on the physician's clinical decision, and patients might not be routinely tested.

Total parenteral nutrition (TPN) is necessary to neonates in neonatal intensive care unit (NICU) for survival and growth because of impossible of enteral feeding. Long-term TPN can be associated with a broad spectrum of hepatobiliary disorder, ranging from mild hepatic dysfunction to severe end-stage liver disease. Cholestasis developed most commonly in neonate, ursodeoxycholic acid (UDCA) is widely used in adult with cholestatic and non-cholestatic liver diseases but there have been limited data on the effects in neonate with PNAC. This study was performed retrospectively to review all medical histories of the total 30 neonates with was administrated UDCA for treatment to parenteral nutrition associated cholestasis (PNAC) at Chungbuk National University Hospital NICU from April 2002 to December 2008. UDCA was administrated at bilirubin is over 2 mg/dl. The criterias for drug evaluation were included hepatic biochemical marker such as direct bilirubin, total bilirubin, AST, ALT, ALP and GGT, TPN therapy period, cholestasis development period, UDCA treatment period, UDCA dosage and adverse effect. In the results, Post-UDCA treatment significant was decreased direct bilirubin, total bilirubin, AST and ALP (p<0.05), and was decreased GGT (p>0.05) and slightly was increased ALT (p>0.05). Reffective timect biDCA was appear at mean $10.5{\pm}1.3$ days, iDCA administration period was mean $64.4{\pm}5.9$ days, cholestasis period was mean $71.9{\pm}6.4$ days and UDCA dosage was mean $22.9{\pm}0.9$ mg/kg/day. Common adverse effects is diarrhea, 5 patients arised mild diarrhea but it possible also related with increased enteral feeding. In conclusion, iDCA can decrease direct bilirubin that major parameter t bcholestasis and oher hepatic biochemical makers. UDCA is effective on PNAC without any serious side effect and cost-effective. Although no greatly shortening cholestasis period, but can protect to develop into severe liver disease and other complication or death. Based on these result, UDCA is recommended for treatment of cholestasis at direct bilirubin is over 2 mg/dl.
