Poststreptococcal glomerulonephritis (PSGN) is one of the most recognized diseases in pediatric nephrology. Typical clinical features include rapid onset of gross hematuria, edema, and hypertension, and cases are typically preceded by an episode of group A ${\beta}$-hemolytic streptococcus pharyngitis or pyoderma. The most common presenting symptoms of PSGN are the classic triad of glomerulonephritis: gross hematuria, edema, and hypertension. However, patients with PSGN sometimes present with unusual or atypical clinical symptoms that often lead to delayed diagnosis or misdiagnosis of the disease and increased morbidity. Additionally, the epidemiology of postinfectious glomerulonephritis (PIGN), including PSGN, has changed over the past few decades. This paper reviews atypical clinical manifestations of PSGN and discusses the changing demographics of PIGN with a focus on PSGN.

Poststreptococcal glomerulonephritis (PSGN) is one of the most well-known and important infectious renal diseases resulting from a prior infection with group A ${\beta}$-hemolytic streptococcus. The typical clinical characteristics of the disease reflect acute onset with gross hematuria, edema, hypertension and moderate proteinuria after the antecedent streptococcal infection. In children, usually PSGN is healed spontaneously but if it combines with fast progressing glomerulonephritis, it would be developed to chronic renal failure. Therefore, it is important to make a fast diagnosis and treatment by simple tools to predict the course and the prognosis of disease. Sonography is a simple tool for diagnosis but there is no typical renal sonographic finding in PSGN, so it is difficult to predict the course and the prognosis of disease by sonographic findings. In comparison between two cases of renal sonographic findings in PSGN, a patient who showed more increased echogenicity in more extended area of renal sonography had the severe results of renal pathology, prolonged treatment period and low serum C3 level. Here, we report the different findings of renal sonography and pathology depending on the degree of severity between two patients. Thus, it is necessary to gather more information from further studies to make a consensus about the relationship between the renal sonography and the prognosis of disease in PSGN.

[ $\beta$ ]-streptococci have been reported as an etiology of Henoch-$Sch{\ddot{o}}nlein$ purpura(HSP), but the role of $\beta$-streptococci in HSP is not yet confirmed. Our report of two HSP patients is as follows : Although the two patients' clinical symptoms resembled those symptoms of HSP, whereas serum $C_3$ decreased in one case, ASO titer increased in both cases and a histological examination of renal biopsy specimens revealed the fetures commonly described in poststreptococcal glomerulonephritis.

가역적 후두부 뇌병증 증후군은 다양한 원인에 의하여 생기는 발생하는 질환으로 갑자기 생기는 두통, 정신상태의 변화, 시력장애, 경련 등이 주증상이다. 영상의학 검사에서는 후두부 백질의 부종이 양측성 혹은 일측성으로 나타난다. 저자들은 A군 사슬알균 감염 후 가역적 후두부 뇌병증 증후군을 보인 환자를 경험하였고 고혈압을 조절한 후 환자는 빠른 시간 내에 신경학적인 회복을 보였다.
