Proteinuria is common in pediatric and adolescent patients. Proteinuria is defined as urinary protein excretion at levels higher than 100-150 mg/m²/day in children. It can be indicative of normal or benign conditions as well as numerous types of severe underlying renal or systemic disease. The school urine screening program has been conducted in Korea since 1998. Since then, numerous patients with normal or benign proteinuria as well as early stage renal diseases have been referred to the hospital. Benign proteinuria includes orthostatic proteinuria and transient proteinuria. Most causes of proteinuria can be categorized into 3 types: 1) overflow, 2) tubular, and 3) glomerular. Although treatment should be directed at the underlying cause of the proteinuria, prompt evaluation, diagnosis, and long-term monitoring of these pediatric patients can prevent potential progression of the underlying disease process. This article provides an overview of proteinuria: its causes, methods of assessment, and algorithmic suggestions to differentiate benign from pathologic renal disease.

The authors experienced a case of congenital nephrotic syndrom, who was 25 days old male infant. We had noted and made diagnosis according to the clinical feature sand laboratory findings such as: (1)Generaliged edema (2)Hypoalbuminemia (3)Hypercholesterolemia (4)Massive proteinuria We had studied on this rare case, and reviewed the literature and referencdes.

Myxomas are uncommon primary cardiac tumours that usually affect the left atrium. We herein report the case of a patient who presented with right heart failure and proteinuria, leading to the diagnosis of atrial myxoma. Surgical resection resulted in resolution of the patient's symptoms.

C1q nephropathy is an immune complex glomerulonephritis defined by predominant mesangial C1q deposition and has no evidence of systemic lupus erythematosus. Patients are usually between the ages of 15 and 30 when diagnosed and have a nephrotic range proteinuria. C1q nephropathy in adult has not been reported yet in Korea. Also it may be accompanied by hematuria, but it is uncommonly manifested hematuria without proteinuria. We experienced a case of C1q mediated glomerulonephritis that manifested by asymptomatic hematuria in adult. A 47-years-old man visited our hospital complaining general weakness and fatigue. Microscopic hematuria was detected on routine examination of urinary sediment so that renal biopsy was carried out. Renal biopsy showed C1q mediated glomerulonephritis. We report a case of C1q mediated glomerulonephritis manifested by asymptomatic hematuria without proteinuria. C1q nephropathy should be added to the differential diagnosis of glomerulonephritis in patients with asymptomatic hematuria.

Amyloidosis is a disease complex associated with deposition of insoluble filbrillar protein in various tissues of the body. Cutaneous lesions are present in up to 40 % of patients with primary and myeloma associated systemic amyloidosis. We present a case of systemic amyloidosis associated with multiple myleoma occuring in 54-year-old male who had waxy papules with petechiae on nasola bial fold, postauricular area, and cheek. The diagnosis was confirmed by Congo red stain, electron microscope, immunelectrophoresis, Bence-Jones proteinuria, immunoperoxidase stain, and bone marow biopsy.

Alport's syndrome is a progressive hereditary kidney disease. The disease is primarily X chromosome- linked but autosomal forms have also been reported. The authors experienced a case of Alport's syndrome in a 19-year-old man who showed persistent hematuria and proteinuria. The diagnosis was based on the presence of hematuria on the pedigree of patient's maternal site and characteristic electron microscopic findings of renal tissue, and persistent hematuria. There was, however, no abnormal finding on audiogram and eye exami-nation. We report this case with a review of literature.
