Adolescent build plotting on body composition chart and the type of diabetes mellitus.

Although the prevalence of type 2 diabetes is increasing, there are cases difficult to categorize into certain type in pediatric diabetic patients. The aims of this study were to detect and choose a proper treatment modality for atypical cases of diabetes mellitus, using the body composition chart. We conducted a retrospective study from August 2005 to 2012 with patients who visited Konkuk University Medical Center, and were diagnosed with diabetes mellitus.

Dense deposit disease in Korean children: a multicenter clinicopathologic study.

The purpose of this study was to investigate the clinical, laboratory, and pathologic characteristics of dense deposit disease (DDD) in Korean children and to determine whether these characteristics differ between Korean and American children with DDD. In 2010, we sent a structured protocol about DDD to pediatric nephrologists throughout Korea. The data collected were compared with previously published data on 14 American children with DDD.

Evaluation of kidney size in children: a pilot study of renal length as a surrogate of organ growth.

Purpose: Somatic growth is an important indicator of health in children. Adequate organ growth is essential in growth and directly related to body growth. We consider renal length as a surrogate of organ growth in growing children.

Microalbuminuria in normal Korean children.

Purpose: Although microalbuminuria is known as a predictor of clinical nephropathy and cardiomyopathy, few studies have investigated the incidence and reference range of microalbuminuria in healthy children. This study aimed to establish a reference range and to study the age-related trend for spot urine microalbumin/creatinine ratio in a Korean pediatric population.

Materials And Methods: 352 healthy children were studied from July 2007 through March 2010.

A case of renal artery stenosis in a child confirmed by multidetector computed tomographic angiography.

Renovascular hypertension is an uncommon disease, but it causes 5-10% of all childhood hypertension. The most common cause of renal artery stenosis is fibromuscular dysplasia, resulting in at least 60% of renovascular hypertension cases. This report describes a case of a renal artery stenosis confirmed by multidetector computed tomographic angiography.

Microalbuminuria in children with urinary tract infection.

Purpose: Microalbuminuria is defined as increased urinary albumin excretion (30-300 mg/day) or microalbumin/creatinine ratio (30-300 mg/g) in a spot urine sample. Although microalbuminuria is a predictor of clinical nephropathy and cardiomyopathy, few studies have investigated microalbuminuria in children with urinary tract infection (UTI).

Methods: Therefore, we compared the spot urine microalbumin/creatinine ratio in pediatric UTI patients with that of control subjects.

Ureteroscopic surgery for a large upper ureteral stone in an infant with bilateral vesicoureteral reflux.

Pediatric urolithiasis is a relatively rare disease that can have lifelong consequences. The management of pediatric urolithiasis should be individualized with careful consideration of the patients' small body sizes, delicate tissues, needs for general anesthesia with every procedure, and risks of long-term complications. Miniaturization of urological instruments has made the treatment of distal ureteral stones by ureteroscopy in children more common, but there are few reports of the ureteroscopic removal of large upper ureteral stones in infants.
