Wegener's granulomatosis is characterized by necrotizing granulomatosis lesion of the respiratory tract, glomerulonephritis and frequently vasculitis involving other organs. The basic pathophysiologic mechanism of Wegener's granulomatosis is not defined yet. However, it may be suspected an autoimmune disease. We experienced a case of Wegener's granulomatosis which are associated with acute renal failure and pneumothorax. The patient suffered from hemoptysis, fever and cough. Despite antibiotic therapy, symtoms did not improved and multiple varying sized nodules were aggravated on chest roentogenogram and serum creatinine elevated 3.4mg/dl. After diagnosis using video associated thoracoscopic surgery, the patient was treated with cyclophsphamide, glucocorticoid and sulfamethoxasole-trimethoprime. With the combination therapy, the patient felt completely well and chest roentogenogram showed lungs were improved and serum creatinine was normal. The patient was readmitted because of right pleuritic pain and dyspnea 15 day after discharge. The patient was developed a right pneumothorax. The lung was easily expanded by intercostal tube drainage with a one way valve. The patient has been treated as an out- patient with immunosuppressive agents continously.

PURPOSE: IgA nephropathy(IgAN) and thin glomerular basement membrane disease(TGBMD) are common glomerular diseases that cause hematuria in childhood. IgAN has characteristics of IgA deposit as the sole or predominantly localized to the mesangium. Recently, it has been reported that thinning of glomerular basement membrane(GBM) is commonly accompanied with precipitation of electron dense deposits in IgAN. We performed this study to examine the frequency of thinning of GBM among children with IgAN and to analysis the correlation between urinary abnormalities and GBM thickness, and furthermore to conduct comparative analysis of the clinical and pathological features of IgAN and TGBMD. METHODS: This study summarizes data collected from Department of Pediatrics, Busan Paik Hospital, Inje Medical College. Data include 51 cases who were diagnosed as IgAN from 1995 to 2000, and 26 cases who were diagnosed as TGBMD from 1990 to 2000 by percutaneous renal biopsy. RESULTS: Males accounted for 29/51(56.9%) patients with IgAN and 8/26(30.8%) of those with TGBMD. The clinical and laboratory features between IgAN and TGBMD were significantly different regarding the incidence of proteinuria(IgAN vs TGBMD: 43.1% vs 3.8%, P=0.001), the incidence of co-appearance of proteinuria with hematuria (41.2% vs 3.8%, P=0.001), total amount of protein in 24 hours collected urine (808+/-188.5 mg vs 251+/-00.7 mg, P=0.001) and the incidence of proteinuria more than 1 gm in 24 hours collected urine (23.5% vs 3.8%, P=0.01). On the contrary, there were no significant differences in the levels of serum albumin, creatinine, BUN, and Ccr between two groups. The mean thickness of GBM in patients with IgAN was293.0+/-9.2 nm(139.7-461.9 nm) and 180.9+/-5.8 nm (110.5-229.5 nm) in patients with TGBMD. The mean GBM thickness revealed significantly thinner in TGBMD compared than those with IgAN (P=0.0001). The frequency of thickness being less than 250 nm was 37.4 +/-34.4% in IgAN and 93.0 +/-7.0% in TGBMD (P=0.0001). But there were no correlations between urinary abnormalities and GBM thickness in patients with IgAN. CONCLUSION: The thinning of GBM would be one of the common pathological findings in IgAN. Moreover, there is no significant correlations between urinary abnormalities and GBM thickness in patients with IgAN. However, patients with IgAN tend to have significantly higher possibilities of proteinuria, co-appearance of proteinuria with hematuria and higher total amount of protein in 24 hours collected urine compared those with TGBMD. These differences might be play an important role as progressive prognostic indicators in patients with IgAN.

PURPOSE: Each ethnic group has a unique life style, including diets. Life style affects bowel movement. The aim of this study is to describe the results of colon transit time (CTT) tests in Korean children who had chronic functional constipation based on highly refined data. METHODS: One hundred ninety (86 males) out of 415 children who performed a CTT test under the diagnosis of chronic constipation according to Rome III criteria at Konkuk University Medical Center from January 2006 through March 2015 were enrolled in this study. Two hundreds twenty-five children were excluded on the basis of CTT test result, defecation diary, and clinical setting. Shapiro-Wilk and Mann-Whitney U, and chi-square tests were used for statistical analysis. RESULTS: The median value and interquartile range (IQR) of CTT was 54 (37.5) hours in Encopresis group, and those in non-encopresis group was 40.2 (27.9) hours (p<0.001). The frequency of subtype between non-encopresis group and encopresis was statistically significant (p=0.002). The non-encopresis group (n=154, 81.1%) was divided into normal transit subgroup (n=84, 54.5%; median value and IQR of CTT=26.4 [9.6] hours), outlet obstruction subgroup (n=18, 11.7%; 62.4 [15.6] hours), and slow transit subgroup (n=52, 33.8%; 54.6 [21.0] hours]. The encopresis group (n=36, 18.9%) was divided into normal transit subgroup (n=8, 22.2%; median value and IQR of CTT=32.4 [9.9] hours), outlet obstruction subgroup (n=8, 22.2%; 67.8 [34.8] hours), and slow transit subgroup (n=20, 55.6%; 59.4 [62.7]hours). CONCLUSION: This study provided the basic pattern and value of the CTT test in Korean children with chronic constipation.

We previously reported that mice lacking JSAP1 (jsap1-/-) were lethal and the brain of jsap1-/- at E18.5 exhibited multiple types of developmental defects, which included impaired axon projection of the corpus callosum and anterior commissures. In the current study, we examined whether the early telencephalic commissures were formed abnormally from the beginning of initial development or whether they arose normally, but have been progressively lost their maintenance in the absence of JSAP1. The early corpus callosum in the brain of jsap1+/+ at E15.5-E16.5 was found to cross the midline with forming a distinct U-shaped tract, whereas the early axonal tract in jsap1-/- appeared to cross the midline in a diffuse manner, but the lately arriving axons did not cross the midline. In the brain of jsap1-/- at E17.5, the axon terminals of lately arriving collaterals remained within each hemisphere, forming an early Probst's bundle-like shape. The early anterior commissure in the brain of jsap1+/+ at E14.5-E15.5 crossed the midline, whereas the anterior commissure in jsap1-/- developed, but was deviated from their normal path before approaching the midline. The axon tracts of the corpus callosum and anterior commissure in the brain of jsap1-/- at E16.5-E17.5 expressed phosphorylated forms of FAK and JNK, however, their expression levels in the axonal tracts were reduced compared to the respective controls in jsap1+/+. Considering the known scaffolding function of JSAP1 for the FAK and JNK pathways, these results suggest that JSAP1 is required for the pathfinding of the developing telencephalic commissures in the early brains.

A fecaloma refers to a mass of accumulated feces that is much harder than a mass associated with fecal impaction. Fecalomas are usually found in the rectosigmoid area. A 10-year-old male with chronic constipation was admitted because of increasing abdominal pain. An abdominal computed tomography scan and a simple abdominal x-ray revealed rapidly evolving mechanical obstruction in the small intestine. Most of the fecalomas are successfully treated by conservative methods such as laxatives, enemas and rectal evacuation. When conservative treatments have failed, surgical intervention may be needed. In this case, an emergency operation was performed and a 4x3x2.5 cm fecaloma was found in the distal ileum. We thus report a case of ileal fecaloma inducing small bowel obstruction in a patient with chronic constipation, who required surgical intervention. When symptoms of acute small intestinal obstruction develop in a patient with chronic constipation, a fecaloma should be considered in differential diagnosis.

Objectives: The aim of this study was to investigate dietary intakes and nutritional status among Uganda primary school children from two selected schools in urban and rural areas. Methods: Data were collected from 350 pupils (6-14 years) in Mpigi district, Uganda. All participants were offered a school lunch meal (usually maize porridge and boiled beans). Dietary survey was conducted in October 2016. Data for dietary intake levels were collected by the 24-hour recall method with trained school staffs. The data were converted into nutrient intakes using the CAN-Pro 5.0 Program and compared with KDRIs to evaluate the nutritional status of the subjects. Diet quality indexes such as nutrient density, nutrient adequacy ratio (NAR), mean adequacy ratio (MAR), and index of nutritional quality (INQ) and a diet diversity index such as diet diversity score (DDS) were calculated to evaluate nutritional status among subjects. Data were analyzed using SPSS statistical programs. Results: Results show that the intakes of most nutrients were significantly different by schools. The nutritional status of micro-nutrients was very low in both schools according to analysis of nutritional indexes such as NARs and INQs. Students from both schools should improve intakes of micro-nutrients related to child growth such as calcium, Vitamin B6, zinc and folate. According to the analysis of dietary diversity, there was difference in dietary patterns by schools presumably due to their locations. Conclusions This suggests that current meals could not provide adequate nutrients for the subjects and urgent nutrition interventions for school food services are needed to improve their nutritional well-being. New foods supplements based on local cuisine are also needed to ensure dietary diversity and sustainable development plans.

PURPOSE: The aim of this study was to establish a simple formula to predict renal length in children using a Technesium-99m dimercaptosuccinic acid (DMSA) scan data, and to compare it with the formula derived from ultrasonography, which is widely accepted. METHODS: Children who underwent a DMSA scan and ultrasonography were reviewed retrospectively, and those who had anatomical urinary tract abnormalities or urinary tract infections were excluded. RESULTS: A total of 230 children (84 males and 146 females; age, 1 month to 16 years; mean age, 16.8 +/- 27.4 months). Mean renal length measured by DMSA scan was longer than that by ultrasonography (6.38 +/- 1.16 vs. 6.02 +/- 1.14 cm; P < 0.001). Renal length was correlated with age, weight, height, and body surface area on the DMSA scan and ultrasonography, and showed the strongest positive correlation with height. The following formulae were established to predict renal length: mean renal length (cm) = 5.433 x height (m) + 2.330 (R2, 0.833) using the DMSA scan data, and mean renal length (cm) = 5.367 x height (m) + 2.027 (R2, 0.853) using ultrasonography data. CONCLUSION: We propose a simple height-based formula to predict renal length in children using a DMSA scan data, and validate it by comparing with ultrasonography formula.

Cogan's syndrome can accompany a variety of systemic vasculitides including aortitis. A 45-year-old woman with a history of typical Cogan's syndrome presented with orthopnea and exertional dyspnea. Echocardiography demonstrated severe aortic valve insufficiency. Computed tomographic angiography demonstrated active vasculitis affecting the ascending and descending aortas and also showed stenosis of the left subclavian artery, both renal arteries, the celiac axis, the superior mesenteric artery, and the right common iliac artery. She received high dose corticosteroid and then underwent an aortic valve replacement. This is the first case of Cogan's syndrome with aortitis in Korea.

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.

BACKGROUND/AIMS: A colon transit time test using radio-opaque markers (CTTRM) is considered the gold standard for evaluating colon transit function. A 24-hour delayed film of barium enema (BE) has been used as a supplementary method in structural evaluations. The aim of this study was to evaluate the utility of a 24-hour delayed BE film for assessing colon transit function in young children with constipation. METHODS: In total, 93 children with constipation who performed both single-contrast BE and CTTRM were enrolled in this study. Of these, the data from 70 children were analyzed (males 33, females 37; mean age [range], 5.63 ± 2.94 [2-14] years). The basic principle of the study is "velocity = distance/time". Time values were identified in both studies, and the colon length and distance of barium movement were measured on the 24-hour delayed BE film. Thus, colon transit velocity values could be calculated using both methods. The correlation between colon transit velocity using a 24-hour delayed BE film versus CTTRM was analyzed statistically. RESULTS: Median value (interquartile range) of colon transit velocity using CTTRM was 1.57 (1.07-2.89) cm/hr, and that using BE of that was 1.58 (0.94-2.07) cm/hr. The Spearman correlation coefficient was 0.438 (P < 0.001) for the overall group. The correlation was strongest in children younger than 4 years (r = 0.537, P = 0.032). CONCLUSIONS: Although the correlation between BE and CTTRM was not very strong, the 24-hour delayed BE film could provide broad information about colon transit function in young children, especially those under 4 years who usually cannot undergo CTTRM.
