The combination of central nervous system abnormalities and renal impairment is a notable characteristic of Galloway-Mowat syndrome (GAMOS), a disease which often accompanies microcephaly, developmental delay, and nephrotic syndrome. Many subtypes exist having various phenotypes and genotypes, and many genetic causes are still being identified. An 18-month-old boy first visited our clinic for seizure, delayed development, and microcephaly. During follow-up visits he developed proteinuria and nephrotic syndrome at the age of 6. Nephrotic syndrome became refractory to treatment. These phenotypes were suggestive of GAMOS. Next generation sequencing was performed for genetic analysis and revealed novel compound heterozygous variants in the WDR4 gene: c.494G>A (p.Arg165Gln) and c.540C>G (p.Ile180Met). This is the first case in Korea of GAMOS involving the WDR4 gene.

Nephrotic syndrome (NS) is associated with cerebral venous sinus thrombosis (CVST), which is a rare cerebrovascular disorder in children. Systemic anticoagulation with heparin is the standard therapy for CVST, and mechanical thrombectomy (MT) has been described as a salvage treatment for adult anticoagulant refractory CVST, However, it has never been reported in children. We describe a case of MT for refractory CVST in a child with NS. A 13-year-old boy with newly diagnosed NS presented to an emergency department with acute headache. A head computed tomography showed acute thrombus in the superior sagittal sinus, straight sinus and transverse sinus. The child was started on heparin therapy, but clinically deteriorated and became unresponsive. In view of the rapid deterioration of the condition after anticoagulation treatment, the patient received intravascular treatment. Several endovascular technologies, such as stent retriever and large bore suction catheter have been adopted. After endovascular treatment, the patient's neurological condition was improved within 24 hours, and magnetic resonance venography of the head demonstrated that the CVST was reduced. The child recovered with normal neurological function at discharge. This case highlights the importance of considering MT for refractory CVST, and we suggest that MT may be considered for refractory CVST with NS in children.

Children who suffer from steroid-resistant nephrotic syndrome (SRNS) require aggressive treatment to achieve remission. When intravenous high-dose methylprednisolone fails, calcineurin inhibitors, such as cyclosporine and tacrolimus, are used as the first line of treatment. A significant number of patients with SRNS progress to end-stage renal disease if remission is not achieved. For these children, renal replacement therapy can also be problematic; peritoneal dialysis may be accompanied by significant protein loss through the peritoneal membrane, and kidney allograft transplantation may be complicated by recurrence of SRNS. Plasmapheresis and rituximab were initially used for treatment of recurrent SRNS after transplantation; these are now under consideration as rescue therapies for refractory SRNS. Although the prognosis of SRNS is complicated and unfavorable, intensive treatment in the early stages of the disease may achieve remission in more than half of the patients. Therefore, timely referral of pediatric SRNS patients to pediatric nephrology specialists for histological and genetic diagnosis and treatment is highly recommended.

Objectives The purpose of this study is to analyze clinical studies on effectiveness of herbal medicine in refractory nephrotic syndrome (RNS). Methods We searched the randomized controlled trials (RCTs) with herbal medicine treatment on RNS from the Pubmed, CNKI, OASIS, NDSL, J-stage, and CiNii. The demographic data, duration of illness, intervention, treatment period, outcome, adverse events, and composition of herbal medicine were analyzed for this study. Results 11 RCT studies were selected and analyzed. The children in the control group were given western medicine therapy, and the treatment group was given herbal medicine along with the same western medicine of the control group. The most commonly used herbal medicines were the prescriptions to treat 'Kidney Deficiency with Blood Stasis (腎虛兼瘀血)' which composed of 'Promoting blood circulation (化瘀)', 'Diuresis-inducing (利水)', or 'Heating Yang (溫陽)' medicine based on 'Replenishing Kidney or Spleen (補腎, 補脾)' medicine. In the treatment group, proteinuria and serum lipid was significantly decreased, serum albumin was significantly increased, and total effective rate was significantly higher than the control group. Hypercoagulation and relapse rate was also significantly reduced. Adverse events were significantly lower in the treatment group. Conclusions Herbal medicine treatment on pediatric RNS can be suggested as a new treatment for children who have less response to the conventional therapy. It can also supplement the limitations of the western medicine by reducing adverse events from the steroids and immuno-suppressive agents, and lower the relapse rate as well.

리툭시맙(Rituximab)은 CD20에 대한 키메라형 IgG1 단클론 항체로 스테로이드 의존성 또는 난치성 신증후군에 대한 새로운 치료약제로 이용되고 있다. 그러나 리툭시맙의 약제 부작용에 대해서는 아직까지 더 많은 연구가 필요하다. 저자들은 스테로이드 의존성 신증후군을 앓고 있던 9세 남아에서 수차례의 리툭시맙 사용 후 기쿠치병(Kikuchi-Fujimoto disease)이 병발한 증례를 보고하는 바이다. 기쿠치병은 자연 회복의 양성 경과를 보이는 조직구 괴사성 림프절염으로 아직 원인은 알려져 있지 않다. 이 증례에서는 환자의 말초 혈액 B 면역세포 수치가 매우 감소되었을 때 발병하였으며, 이후 환자의 B 면역세포가 회복되면서 서서히 자연 소실되었다. 이 증례는 비록 병리 조직학적 진단은 뒷받침되지 못하였지만 임상적으로 진단된 기쿠치병이 리툭시맙 사용의 부작용으로 발생할 수 있다는 연관성을 시사하는 첫 번째 보고로써, 소아 신증후군에서 리툭시맙 사용의 안전성에 대한 이해의 폭을 넓히고자 하였다.

Pleural effusion due to hepatic cirrhosis and ascites is well known. But rarely a pleural effusion may develop in a cirrhotic patient in the absence of detectable ascites. The differential diagnosis of a right-sided transudative pleural effusion in a patient with chronic liver disease with or without ascites includes congestive heart failure and nephrotic syndrome. These diseases are usually ruled out with standard clinical tests. Patients with hepatic hydrothorax should be treated with fluid restriction, diuretics and the correction of hypoalbuminemia. Patients with severe symptoms due to refractory hepatic hydrothorax might benefit from pleural sclerosis and surgical closure of diaphragmatic defect. We experienced a case of right-sided pleural effusion in liver cirrhosis without ascites.

Focal segmental glomerulosclerosis(FSGS) has been detected in approximately 10% of cases of Idiopathic nephrotic syndrome in children, and exhibits a poor response to initial steroid therapy, as well as a higher rate of progression to chronic renal failure and relapse after kidney transplantation. We describe a case of an eleven year-old boy with steroid-resistant FSGS who exhibited a response to a second trial of cyclosporin h(CsA) therapy. At the age of 26 months, this patient was diagnosed with steroid-resistant FSGS. For 9 years, he had undergone a gauntlet of therapies to induce remission; oral steroids, cyclophosphamide, methylprednisolone(mehyIPd) pulse therapy, CsA, and ibuprofen therapy. Although these therapies failed to induce remission, the patient's renal function remained In the normal range during the nine years of treatment. At the age of ten years, the patient's proteinuria decreased, and complete remission was attained with a second administration of CsA, coupled with a low dose of oral steroids. This patient continues to receive CsA without relapse. Therefore, our major concern involves the possibility of relapse after the discontinuation of CsA therapy Our findings in this case suggest that, in cases of refractory FSGS, if renal insufficiency does not emerge, aggressive therapy for the amelioration of proteinuria should be continuously pursued.

목 적 :소아의 원발성 신증후군 중 $85\%$이상을 차지하는 미세변화형 신증후군(MCNS)은 스테로이드 치료로 완전 관해가 잘 오는 예후가 양호한 질환이다. 반면 국소성 분절성 사구체 경화증(FSGS)은 치료에 잘 반응하지 않고 신부전으로의 진행 및 신이식 후의 재발률이 높아 장기 예후가 나쁜 것으로 알려져 있다. 신생검상 MCNS로 진단된 환아 중 여러 약물 요법에 반응이 불량하거나 증세의 악화가 있어 추적 관찰하며 시행한 2차 신생검상 FSGS로 조직 소견의 변화를 보이는 경우가 드물게 있어 본 저자들은 이들의 임상 양상의 특징을 비교 고찰하여 MCNS로부터 FSGS로 이행될 수 있는 위험 요인을 알아보고자 본 연구를 시행하였다. 대상 및 방법 : 1988년 1월부터 1999년 5월까지 세브란스 병원 소아과에서 신장생검 상 미세변화형 신증후군 및 국소성 분절성 사구체 경화증으로 진단받고 치료 중인 환아 296명을 대상으로 하였다. 조직 병리 소견상 미세변화형 신증후군을 보인 군(MCNS군), 국소성 분절성 사구체 경화증을 보인 군(FSGS군)및 MCNS로부터 FSGS로 이행된 군(이행군)등 3개 군으로 나누어 이들 각 군의 임상 양상 차이를 비교하였다. 결 과 : 대상 환아는 MCNS군 241명($81.4\%$), FSGS군 47명($15.9\%$), 이행군 8명($2.7\%$)으로 총 296명 이었으며, 평균 발병 연령은 MCNS군 $6.0{\pm}2.6$세, FSGS군 $7.2{\pm}4.3$세, 이행군 $8.3{\pm}2.6$세였고, 남녀비는 MCNS군 3.7:1, FSCS군 1.8:1, 이행군 3:1이었다. 내원 당시의 혈뇨, 고혈압, 24시간 뇨단백량, 혈청 알부민, 혈청 콜레스테롤, 혈청 크레아티닌 등을 비교하였으며, 이중 이행군:FSGS군 간의 비교에서 24시간 뇨단백량 $686:342mg/m^2/hr$(P<0.05), 혈청 알부민 1.92:2.47g/dL(P<0.05), 혈청 콜레스테를 494:343 mg/dL(P<0.05)으로 의미있는 차이를 보였고, 이외에는 이행군과 FSGS군 또는 MCNS군과의 사이에 의미있는 차이를 보이지는 않았다. 스테로이드 치료에 전혀 반응을 보이지 않는 경우는 MCNS군 $13.3\%$,이행군 $12.5\%$,FSGS군 $59.6\%$로 FSGS군이 의미있게 많았으며(P<0.05), 스테로이드 이외의 면역억제제 치료가 필요했던 경우는 MCNS군 $58.5\%$, 이행군 $100\%$, FSGS군 $80.8\%$로 MCNS군에 비해 이행군과 FSGS군이 의미있게 높았다(P<0.05). 평균재발횟수는 MCNS군 $0.84{\pm}0.21$회/6개월, 이행군 $1.07\pm}0.53$회/6개월로 의미있는 차이는 없었으며, 관해에서 첫 재발까지의 기간 역시 MCNS군 6.94${\pm}$1.92개월, 이행군 $6.71{\pm}4.89$개월, FSGS군 $5.27{\pm}12.48$개월로 각 군간의 의미있는 차이는 없었다. 결 론 : 미세변화형 신증후군에서 치료 경과중 국소성 분절성 사구체 경화증으로 이행된 예는 전체 MCNS의 249명중 8명으로 $3.2\%$였다. 이들의 임상양상의 특징을 비교 고찰한 결과 이행여부를 예측할 수 있는 위험요인은 없었다. 미세변화형 신증후군으로 진단된 환아 중에서 스테로이드 치료에 반응이 없거나 자주 재발하는 경우, 또는 강력한 면역치료에도 관해가 오지 않는 경우 등에는 신장 조직 생검을 재시행하여 국소성 분절성 사구체 경화증으로의 이행 여부를 확인해야 하겠다.
