  • Purpose: The aim of this study is to evaluate the clinical utility of late 6-month dimercapto-succinic acid (DMSA) renal scan in predicting vesicoureteral reflux (VUR) and long-lasting renal scars in children with first acute pyelonephritis (APN). Methods: A retrospective case study of children admitted with APN from January 2010 to July 2017 was performed. The study included patients with voiding cystourethrography (VCUG) and acute and late 6-month DMSA scan. We analyzed the clinical, laboratory and imaging findings of patients with and without late cortical defects at 6 months and those with or without VUR. Results: Among 145 children with APN, 50 (34.5%) had cortical defects on the late DMSA renal scan and 60 (41.4%) showed VUR. Thirteen of 38 (34.2%) children undergoing 18-month DMSA renal scan showed a long-lasting renal scars. Compared with children without late cortical defects, patients with late 6-month cortical defects had a higher incidence of VUR and long-lasting renal scars, and relapse of UTI (all P<0.05). In a multivariable analysis, both high-grade VUR and relapse of UTI were independently correlated with the presence of late 6-month cortical defects (P<0.05). Late cortical defects and relapse of UTI were also associated with the presence of VUR (P<0.05). Only the late 6-mo cortical defects was an independent predictor of long-lasting renal scars in children with APN (P<0.05). Conclusion: An abnormal late 6-month DMSA renal scan may be useful in identifying VUR and long-lasting renal scars in children diagnosed with APN.

  • Prosthetic valves are being widely used in the treatment of heart valve disease. Prosthetic valve endocarditis (PVE) is one of the most catastrophic complications seen in these patients. In particular, prosthetic valve dehiscence can lead to acute decompensation, pulmonary edema, and cardiogenic shock. Here, we discuss the medical management of late PVE in a patient with a prior history of late and redo early PVE and recurrent dehiscence. According to the present case, we can summarize the learning points as follows. A prior history of infective endocarditis increases the risk of relapse or recurrence, and these patients should be evaluated very cautiously to prevent late complications. Adequate debridement of infected material is of paramount importance to prevent relapse. A history of dehiscence is associated with increased risk of relapse and recurrent dehiscence.

  • Purpose: The use of a 12-week steroid regimen (long-term therapy, LT) for the first episode of idiopathic nephrotic syndrome (NS) reportedly induces a more sustained remission and lower relapse rate than previous regimens, including an 8-week steroid regimen (short-term therapy, ST). Here, we assessed the potential for selective application of 2 steroid regimens (LT vs. ST) based on the days to remission (early responders [ER] vs. late responders [LR]) for the first idiopathic NS episode in children. Methods: Patients were divided into 4 subgroups (ST+ER, ST+LR, LT+ER, and LT+LR) according to the initial steroid regimen used and rapidity of response; the baseline characteristics, relapse rates, and cumulative percentage of children with sustained remission were then compared among the 4 subgroups. Results: Fifty-four children received ST, and the remaining 45 children received LT. As observed in previous studies, children receiving LT showed significantly lower relapse rates during the first year after the first NS episode than those receiving ST. The ST+ER group showed significantly lower relapse rates during the first one year and two years after the first NS episode than the the ST+LR group, whereas there were no significant differences of the relapse rates and duration to the first relapse between the ST+ER and LT+ER groups. Conclusion: We suggest that the initial steroid regimen in idiopathic NS patients can be shortened according to the duration to remission i.e., LT in patients achieving remission after the first week of steroid therapy, and ST in those achieving remission within the first week of steroid therapy.

  • Minimal change disease (MCD) in children has a favorable long-term prognosis, and development of end-stage renal disease is very uncommon; less than 5%. In the first case of its kind, we report a 21-year-old female with a history of MCD at the age of 6, who had late relapse subsequent to a motorcycle accident resulting in a de-gloving skin injury and intensive care unit admission. MCD was confirmed by normal light microscopy, podocyte effacement on electron microscopy and absence of any deposits on immunofluorescence 3 weeks after the incident due to critical illness. It is postulated that the skin injury is what caused the relapse of MCD.

  • Lip canting is associated with facial asymmetry, and is one of the most challenging problems in surgical correction of facial deformities. The author corrected lip canting using bioabsorbable devices during orthognathic surgery. Soft tissue suspension procedures were performed on four patients with facial asymmetry. Lip lines improved for all patients. Over an observation period of five years, no complications were noted, nor did any late relapse develop. Furthermore, as time past, the effect of the Endotine suspension procedure increased probably due to induction of fibrosis on surrounding soft tissues.

  • Objective: To find out clinical features and long-term outcomes of idiopathic childhood nephrotic syndrome(NS) patients with late steroid resistance(LSR)/late steroid sensitiveness(LSS). Patients and Methods: A retrospective chart review was performed on 480 patients diagnosed with idiopathic childhood NS at Asan Medical Center Children's Hospital from 1990 to 2013. Twenty-four patients whose responsiveness to steroids changed over a minimum 2 year follow-up period (2-17.5 years) were investigated. All patients had undergone a renal biopsy. Results: Among 480 nephrotic children, 428 (89%) were sensitive to the first steroid course. Of those who initially responded, 11 (2.5%) developed resistance to steroid therapy after relapses. LSR mostly developed between 1 month and 1 year after the initial episode. Six patients showed a minimal change and five showed focal segmental glomerulosclerosis (FSGS). Nine (82%) responded to cyclosporine or methylprednisolone pulse therapy. Of these, two had no further relapse, whereas the other seven experienced several relapses that ranged in length from 1.1 to 13.9 years. Three of the nine who initially responded to immunosuppression went on to experience several changes in steroid responsiveness. Two (18%) with resistance to immunosuppressants, including steroids, eventually progressed to end stage renal disease. Among the 52 patients (11%) who were initially steroid resistant, 13 (23%) were converted to steroid sensitive at relapses. Among these, 9 showed minimal change and 4 showed FSGS. Two had no further relapse and the other 11 responded to steroids on subsequent relapses ranging in length from 1.3 to 9.4 years. All these patients have had no further changes in steroid responsiveness with normal renal function. Conclusions: In this study, 2.5% of initial steroid responders and 25% of initial steroid non-responders changed their responsiveness to steroids at subsequent relapses. Eighteen percent of LSR patients developed end stage renal disease. All of the LSS patients showed preserved normal renal function. Responsiveness to immunosuppressants seemed to be the most important factor determining longterm outcomes in LSR/LSS patients.

  • 하악 전돌증의 치료를 위해 외과적인 술식이 교정임상분야에 도입된 이래로 많은 임상적인 성공사례가 보고되어 왔으며 최근에 와서는 하악골 후퇴술의 대표적 술식으로 구내 시상 분할 골절단술(SSRO)과 구내 상행지 수직 골절단술(IVRO)이 주로 시행되고 있다. 물론 이 두가지 술식 모두 만족스러운 술후 결과를 얻을 수 있으나 술후 안정성과 재발의 양상과 정도가 다르게 나타나고 있다. 그러나 하악 후퇴술후 시간경과에 따른 재발의 정도에 관한 국내의 연구는 국외에 비해 다소 부족한 상황이며, 특히 시상 분할 골절단술과 상행지 수직 골절단술후의 재발양상에 관한 비교 연구는 아직 없는 실정이다. 이에 저자는 골격성 III 급 부정교합자의 악교정 수술 후 수술방법에 따른 재발 양상과 장기적 안정성을 알아보고자 구내 시상 분할 골절단술로 시행받은 24명(남자 10명, 여자 14명)과 구내 상행지 수직골절단술로 시행받은 26명 (남자 10명, 여자 16명)의 수술 직전(T1), 수술 직후 48시간 이내(T2), 수술 후 4-8주(T3), 수술후 6개월 이상(T4)등 4장의 측모두부방사선 사진을 계측하여 두 군간의 기간별 재발 양상과 각 군내의 타 변수들과의 상관성에 관해 검증하여 다음과 같은 결과를 얻었다. 1. 하악골의 수평적인 초기 재발은 시상 분할 골절단술군에서는 전방 이동, 상행지 수직 골절단술군에서는 후방 이동양상을 보였다. 2. 두 군 모두에서 하악골의 수직적인 초기 재발과 후기 재발은 전안면고경이 감소하는 쪽으로 일어났으며 두 군간의 유의차는 없었다. 3. 시상 분할 골절단술군에서 수술시 근심절편의 후방회전이 많을수록 하악골의 수평적인 후기 재발이 더 전방으로 일어났다. 4. 두 군 모두에서 수술시 하악골 후퇴량이 많을수록 하악골의 수평적인 초기 재발이 더 전방으로 일어났다.

  • Purpose: To evaluate the treatment outcome and prognostic factor of postoperative radiotherapy for extremity soft tissue sarcoma (STS). Materials and Methods: Forty three patients with extremity STS were treated with conservative surgery and postoperative radiotherapy from January 1981 to December 2010 at Korea University Medical Center. Median total 60 Gy (range, 50 to 74.4 Gy) of radiation was delivered and 7 patients were treated with chemotherapy. Results: The median follow-up period was 70 months (range, 5 to 302 months). Twelve patients (27.9%) sustained relapse of their disease. Local recurrence occurred in 3 patients (7.0%) and distant metastases developed in 10 patients (23.3%). The 5-year overall survival (OS) was 69.2% and disease free survival was 67.9%. The 5-year local relapse-free survival was 90.7% and distant relapse-free survival was 73.3%. On univariate analysis, no significant prognostic factors were associated with development of local recurrence. Histologic grade (p = 0.005) and stage (p = 0.02) influenced the development of distant metastases. Histologic grade was unique significant prognostic factor for the OS on univariate and multivariate analysis. Severe acute treatment-related complications, Common Terminology Criteria for Adverse Events (CTCAE) grade 3 or 4, developed in 6 patients (14.0%) and severe late complications in 2 patients (4.7%). Conclusion: Conservative surgery with postoperative radiotherapy achieved a satisfactory rate of local control with acceptable complication rate in extremity STS. Most failures were distant metastases that correlate with tumor grade and stage. The majority of local recurrences developed within the field. Selective dose escalation of radiotherapy or development of effective systemic treatment might be considered.

  • 목적 : 소세포 폐암 환자에서 생존율이 향상됨에 따라서 뇌전이의 임상적 중요성이 커지고 있다. PCI 는 뇌전이 빈도를 감소시키며 특히 완전관해된 제한병기 소세포 폐암 환자에서는 생존기간의 연장까지 가져온다는 보고도 있다. 저자들은 완전관해가 된 제한병기 소세포 폐암환자에서 PCI를 시행한 후 뇌전이의 빈도, 생존율 및 임상상을 알아보고자 하였다. 대상 및 방법 : 1989년 3월부터 1999년 9월까지 충남대학교병원에 입원하여 조직학적으로 소세포 폐암으로 확진되고 병기분류상 제한병기로 분류된 후 항암 화학요법 및 방사선치료후 완전관해가 된 환자중 PCI를 시행 받은 42명올 대상으로 후향적분석을 하였다. 항암 화학요법은 초치료로 VPP/CAV교대요법을 6회이상 시행 하였고, 흉부 방사선치료는 동시치료군이 38.1%, 연속치료군이 61.9%였다. 결과 : 대상환자의 88.1%가 남자였고, 중앙연령은 58세였다. 중앙 관찰기간은 18.1개월이었다. 경과 관찰 중에 57.1%에서 전이 또는 재발하였는데, 뇌전이는 14.3%에서 발생하였고, 폐 원발병소에서 재발된 경우가 35.7%로 가장 많았다. 평균 무병생존기간은 1,090일(중앙값 305일), PCI후 뇌전이가 발생하기까지는 평균 2,548일, 뇌전이를 제외한 전이 및 재발되기까지는 평균 1,395일(중앙값 460일)이었다. 생존기간의 중앙값은 21.1개월, 2년생존율은 41.7% 이었다. 전이 및 재발이 발생한 군의 평균 생존기간은 642일(중앙값 489일), 발생하지 않은 군의 평균 생존기간은 2,622일로 유의한 차이가 있었으나, 뇌전이 유무에 따른 생존기간의 차이는 없었다. 사망원인은 원발 병소의 재발 및 전신질환에 의한 사망이 많았고(85.7%), 뇌전이자체에 의한 사망은 14.3%이었다. 결론 : 완전관해가 된 제한병기 소세포 폐암 환자에서 PCI는 뇌전이를 감소시키고 지연시키는 경향이 있었다. 전이 및 재발이 있는 군에서 생존기간이 짧았으나 뇌전이 유무에 따른 생존기간의 차이는 없었고 주된 사망원인이 뇌전이보다는 원발병소의 재발과 전이 및 전산질환에 의한 것이 대부분이어서, 생존율을 높이기위해서는 원발병소의 재발과 전이 및 전신질환에 의한 것이 대부분이어서, 생존율을 높이기 위해서는 원발병소의 재발 및 전이를 감소시킬 수 있는 효과적인 치료방법의 개발 및 전신진환의 적절한 조절이 필요한 것으로 생각된다.

  • 악골의 골격적 부조화를 가진 환자의 교정치료는 악교정 수술을 필요로 하고, 악교정 수술에 의해 교합평면각은 변화된다. 특히 전치부 개교를 동반한 III급 부정교합 환자에서 치아안면 기형을 치료하기 위한 교합평면각의 변화에 대하여 많은 논란이 있어 왔다. 교합평면각을 증가시키는 하악골의 시계 방향 회전(clockwise rotation)은 전치부 개교에 대한 적절한 치료법으로 추천되어 왔고 하악골의 반시계 방향의 회전(counterclockwise rotation)은 하악지 고경을 증가시키는 방향으로 하악골을 회전시킨다는 개념으로 인해 재발(relapse)을 유발하는 불안정한 수술 방법으로 인식되어 왔다. 본 연구는 전치부 개교를 동반한 골격성 III 부정교합 환자에서 교합평면의 반시계 방향 회전을 동반한 하악지 시상분할 골절단술 시행 후 교합평면각의 변화와 술후 안정성과의 관계를 평가 하고자 하였다. 하악지 시상분할 골절 단술과 rigid fixation으로 치료받은 환자 25 명 (평균연령 20.6세)을 대상으로 하여 수술 직전(T1), 술후 2주내(T2), 그리고 술후 6 개월 이후(T3)에 촬영한 측모 두부계측 방사선 사진을 통계분석한 결과(Paired t-test, Pearson correlation analysis), 다음의 결론을 얻었다. 1. 악교정 수술 후(T2) 하악평면각은 $2.9^{\circ}$ 감소하였고 SN 평면에 대한 하악 교합평면의 각도는 $2.7^{\circ}$ 감소하였다. 술후 6 개월경과 후(T3) 후안면 고경의 감소로 인해(P<0.01) 하악 평면각은 $1.0^{\circ}$ 증가하였으나 하악 교합평면의 경사도는 변화되지 않았다. 2. 악교정 수술 후 시간 경과(T3)에 의해 발생한 수평적 재발은 하악골의 전방 이동량이 B점에서 1.6 mm로 수술시 전체 후방 이동량의 약$22\%$였다. 전안면 고경에서는 수직적 재발이 발생하지 않았으나,후안면 고경은 감소하였다. (P<0.01). 3. 수평적 재발과 상관관계를 보이는 항목은 하악평면각 이었고(P<0.01) 수술 6 개월경과 후 후안면 고경의 감소와 상관관계가 있는 요소로는 수술시 하악골의 후방 이동량(P<0.01), 하악지 고경의 증가량(P<0.01), 그리고 하악평면각의 감소량(P<0.01) 등이 있었다. 4. 수술시 하악 교합평면 경사도의 변화량과 술후 재발과는 상관관계가 없었다.
