RESUMO
BACKGROUND: Although lower urinary tract symptoms (LUTS) show a higher prevalence with age, few studies have reported the trend of these examination tools including uroflowmetry, urodynamic study and cystoscopy. METHODS: We evaluated the trend of performance of uroflowmetry, urodynamic study and cystoscopy by using National Health Insurance Data from 2010 to 2015. Primary outcome findings included cumulative number of patients per year, cumulative age-standardized patient rate per year and per age group, and correlation between the number of patients per year and the percentage of population per year in each age group. RESULTS: The overall trend for frequency of uroflowmetry and cystoscopy showed an increasing pattern (P < 0.001, respectively) while the trend for frequency of urodynamic study showed a decreasing pattern (P < 0.001). After age standardization, the overall trend showed similar results. Correlation between the number of patients per year and the percentage of population per year showed a positive correlation in the 50s age group and the above 70s age group (P = 0.003 and < 0.01, respectively) on uroflowmetry and in the above 70s age group (P < 0.01) on cystoscopy. Urodynamic study showed negative correlations in the 50s age group and the above 60s age group (P = 0.001 and 0.01, respectively). CONCLUSION: National trend for frequency of uroflowmetry, urodynamic study and cystoscopy showed a different trend. The increasing trend of uroflowmetry and cystoscopy was related with growth of the aged population. However, urodynamic study showed a decreasing trend regardless of the age group.

Until recently, fermentation was the only processing used to improve the functionality of wheat germ. The release of 2,6-dimethoxy-1,4-benzoquinone (DMBQ) from hydroquinone glycosides during the fermentation process is considered a marker of quality control. Here, we treated wheat germ extract with citric acid (CWG) to release DMBQ and examined the anti-inflammatory activity of this extract using a lipopolysaccharide-activated macrophage model. Treatment of wheat germ with citric acid resulted in detectable release of DMBQ but reduced total phenolic and total flavonoid contents compared with untreated wheat germ extract (UWG). CWG inhibited secretion of the pro-inflammatory cytokines tumor necrosis factor-α, interleukin (IL)-6, and IL-12 and the synthesis of cyclooxygenase-2, while UWG only decreased IL-12 production. CWG and UWG induced high levels of anti-inflammatory IL-10 and heme oxygenase-1. CWG specifically inhibited phosphorylation of NF-κB p65 and p38 kinase at 15 min after LPS stimulation. Our study showed that citric acid treatment enhanced the anti-inflammatory activity of wheat germ extract.

BACKGROUND/PURPOSE: The purpose of this report was to review the results of the antegrade continence enema (ACE) procedure and to compare the outcomes of right and left colon ACEs in children. METHODS: Thirty patients who underwent an ACE between 1998 and 2005 were analyzed. Data were obtained based on the following parameters: postoperative soiling, catheter insertion time, colonic washout time, quality of life, and abdominal pain during and after the ACE. Twenty-nine patients were followed for an average of 3.8 years (range, 4 months-7.3 years). RESULTS: Right colon ACEs were performed in 23 patients, and left colon ACEs were performed in 7 patients. The common complications of the ACE included abdominal pain during and after the ACE (51.7%) and stoma strictures (41.4%). The overall ACE success rate was 24/29 (82.8%; right colon ACE, 18/29; left colon ACE, 6/29). Twenty-three patients (95.8%) believed their quality of life was improved. There were no significant differences in complications or outcomes between the right and left ACEs. CONCLUSIONS: An ACE is an effective treatment for children with fecal incontinence. A left colon ACE has similar efficacy as a right colon ACE in managing fecal incontinence in children.

PURPOSE: This study was performed to investigate whether compression/stretching of the spermatic cord or blunt dissection influences testicular development and fertility. In addition, the authors evaluated whether the extents of testicular damage differ between these 2 surgical manipulations. METHODS: Forty-four prepubertal male Sprague-Dawley (SD) rats (Harlan Sprague-Dawley Inc, Indianapolis, Ind) were divided into 3 groups: (1) the control group (CG) animals underwent a sham operation in the right groin, (2) the experimental group 1 (EG1) underwent compression/stretching of the right spermatic cord, and (3) the experimental group 2 (EG2) underwent dissection around the right spermatic cord structures. Testicular volumes, weights, mean seminiferous tubular diameters (MSTDs), mean testicular biopsy scores, and numbers of offspring and of pregnant females were evaluated. RESULTS: Right (operative) and left (nonoperative) testicular volumes were smaller in the EG2 group than in the CG or EG1 groups. Left MSTDs in the EG1 and EG2 groups increased more than in the CG group. Numbers of Sertoli cells in left testes differed in the 3 groups, in the order EG1 < CG < EG2. Mean testicular biopsy scores, offspring numbers, and pregnant female numbers were no different in the 3 groups. CONCLUSIONS: Both surgical manipulations influenced testicular growth, but they did not compromise spermatogenesis or fertility in SD rats.

BACKGROUND: In the current era of transplantation and therapeutic endoscopy, the role of the distal splenorenal shunt (DSRS) for portal hypertension (PH) has diminished. We reviewed the outcome of the use of DSRS in children to determine the usefulness of this operation. METHODS: In the follow-up course for PH from 1987 to 2006, 15 patients who developed severe thrombocytopenia (platelet count <50 x 10(3)/mm(3)) and/or leukopenia (WBC count <3000/mm(3)) with normal liver function were referred for DSRS. Primary diagnosis was portal vein thrombosis (N=10) and congenital hepatic fibrosis (N=5). Platelet, WBC count, liver function test, and spleen size were checked before and after DSRS. Shunt patency was accessed postoperatively. Operative morbidity, mortality, and long-term outcomes were measured. RESULTS: Platelet count and WBC count increased in individual patients. Mean value of each count increased significantly after DSRS (p=0.002, .004, respectively). Spleen size decreased significantly (N=7, p=0.018). Shunt patency rate was 100%. There was one postoperative complication and no postoperative mortality. Two patients developed portopulmonary hypertension. No patients underwent subsequent transplantation or endoscopic treatment for gastroesophageal varices after DSRS. CONCLUSIONS: DSRS is an effective and reliable procedure for children with PH and is still useful for selected pediatric patients.

PURPOSE: Although the incidence of choledochal cyst (CC) diagnosed in the prenatal or neonatal period is increasing, excision of CC in early infancy is not universally recommended. To validate the rationale of excision of CC in the neonatal period, operative complications and the histologic grade of liver fibrosis at the time of excision of CC were compared in three age groups. METHODS: 198 patients who underwent excision of CC, were divided into three age groups, i.e., within 30 days old (group 1, n = 11), 1 to 12 month-old (group 2, n = 40) and over 12 month-old (group 2, n = 147). Retrospective review of their medical records was performed. RESULTS: The overall operative complications were 12 (7 cholangitis, 4 bleeding, 1 ileus). No complication occurred in the group 1. The grade of liver fibrosis had statistically significant positive correlation among groups. CONCLUSION: Excision of CC in the neonatal period is a safe procedure. The grade of liver fibrosis increased with age. These results support the rationale of early excision of CC.

BACKGROUND/PURPOSE: The aim of the study was to review the gastrointestinal abnormalities occurring in association with situs anomalies. METHODS: Patients with situs anomalies were identified from the medical records of pediatric patients of Seoul National University Children's Hospital from January 1980 to July 2004. Retrospective study was undertaken. Diagnosis was made on the basis of the information obtained from a combination of echocardiography, angiography, abdominal ultrasonography, liver scan, upper gastrointestinal study, or abdominal computed tomography. RESULTS: A total 67 patients diagnosed as having situs anomalies were identified. There were 40 males and 26 females (1.54:1). Of these 67 patients, 45 patients (67%) were diagnosed as having situs inversus, 16 patients (24%) as having right isomerism, and 6 patients (9%) as having left isomerism. Of 45 patients with situs inversus, there were 26 patients (58%) who had intraabdominal abnormalities. These were duodenal atresia, biliary atresia, gastroschisis with malrotation, congenital hepatic fibrosis, tracheoesophageal fistula (type C), Currarino's triad, and pheochromocytoma. Of 16 patients with right isomerism, there were 14 patients (88%) who had intraabdominal abnormalities. These were hiatal hernia and diaphragmatic hernia. Of 6 patients with left isomerism, there were 4 patients (67%) who had intraabdominal abnormalities. These were malrotation and biliary atresia. CONCLUSION: When a patient is noted to have congenital heart disease as part of situs anomalies, or if an atypical position of organs is noted at imaging evaluation, we recommend that the patient undergo chest radiography, abdominal ultrasonography, upper gastrointestinal study, and abdominal computed tomography.

INTRODUCTION: Hepatocellular carcinoma (HCC) is a rare pediatric malignancy that is usually advanced at diagnosis, with a relatively poor prognosis. Extensive treatment, including complete tumor resection, is believed to be necessary for cure. This study was performed to analyze treatment results and to search for prognostic factors of pediatric HCC. METHODS: Between March 1982 and February 2004 a total of 16 children had been diagnosed as having HCC in our institution, and a retrospective analysis was performed. RESULTS: The median age at diagnosis was 10.5 years, and the male/female ratio was 11:5. As a predisposing condition, hepatitis B virus (HBV) infections were present in 11 (68.8%) and liver cirrhosis in 8 (50.0%). Including 1 patient with a liver transplant, 4 patients (25.0%) underwent a primary operation with complete tumor resection, and 11 (68.8%) received neoadjuvant chemotherapy because of their inoperable state at diagnosis. After neoadjuvant chemotherapy, complete tumor resection was performed in four (36.4%). Thus complete resection was undertaken in a total of eight patients (50.0%). The estimated 5-year survival rate of all patients was 27.3%. The 5-year survival rate for patients who underwent complete tumor resection was 62.5%, and for those who underwent palliative resection or no operation it was 0%. The statistically significant prognostic factors were tumor stage, presence of metastasis, and complete tumor resection. CONCLUSIONS: This study confirmed that complete tumor resection is essential for cure in pediatric patients with HCC, and neoadjuvant chemotherapy improves the tumors' resectability.

BACKGROUND/PURPOSE: Chronic intestinal pseudo-obstruction (CIPO) is characterized by symptoms of intestinal obstruction in the absence mechanical blockage. The main objectives in the treatment of CIPO include maintenance of adequate nutrition and restoration of intestinal propulsion. Our aim was to document the results of surgical treatment and the long-term results of CIPO in children. METHODS: The cases of 22 children (14 boys and 8 girls) who underwent surgical treatment for CIPO between January 1985 and April 2004 were reviewed. Patients at initial presentation ranged in age from 1 day to 11 years (median, 3.5 months). The diagnosis of CIPO was based on clinical signs and symptoms, coupled with radiological and histological findings. Patients' outcomes fell into 4 groups, according to evaluations of oral intake, weight gain, and parenteral nutrition: expired, poor, fair, or good. RESULTS: In 3 cases of localized disease, both total gastrectomy and total colectomy were performed in combination. Of 19 cases of generalized disease, 7 patients received enterostomy and/or intestinal biopsy, followed by total colectomy and Duhamel operation. Another 4 of those 19 patients underwent enterostomy repair, and 2 were treated by small bowel resection. In terms of outcome, 5 patients were expired, 5 were classified as poor, 4 were described as fair, and 8 had outcomes that fell into the good category. In expired patients, the causes of death were either line-associated sepsis or hypovolemic shock associated with intestinal obstruction. The only cases in which the outcomes were good were cases in which there was evidence of intestinal neuronal dysplasias. CONCLUSION: We suggest that operative treatment should be considered, because of a high probability of both difficult diagnosis and intractable symptoms, which are unresponsive to medical therapy.

PURPOSE: In this study, the authors analyzed the effect of experimentally induced gastroschisis on pulmonary hypoplasia in fetal rabbits with congenital diaphragmatic hernia (CDH). METHODS: Twenty-three pregnant rabbits underwent fetal surgery on gestational day 24 through 27. A left diaphragmatic hernia was created in 1 fetus (DH group) from each rabbit, and a left diaphragmatic hernia with gastroschisis was created in another fetus (GS group). The fetuses were delivered on gestational day 27 through 33. Histologic and morphometric examination of the lungs in each group was done. RESULTS: In the DH group, the lungs were hypoplastic with a decrease in lung weight to body weight ratio and an increase pulmonary arterial medial wall thickness. The alveolar septae were markedly thickened with increased interstitial tissue and diminished alveolar air spaces. In the GS group, the alveolar septae were thickened but narrower than those of DH group, and air spaces were increased. The pulmonary arterial wall was markedly thickened in the DH group but only slightly thickened in the GS group. CONCLUSIONS: Pulmonary hypoplasia seen in newborn rabbits after experimentally induced diaphragmatic hernia is less severe in those rabbits with both gastroschisis and DH.

Pheochromocytoma is one of the potentially fatal causes of childhood hypertension. The study aims to analyze the results of our experiences in pheochromocytomas and the long-term results of its surgical treatment in children. The records of 15 children (11 boys, 4 girls) treated for pheochromocytoma in our unit during the period of 1984 and 2002 were reviewed retrospectively. The average age at surgery was 11.7 yr (range 6 yr 9 months-15 yr 7 months). Localized disease is defined as the cases without the invasion of surrounding tissue, regional disease as the invasion of surrounding tissue and metastatic disease as distant metastases. The mean follow-up after pheochromocytoma excision was 95 months (range 5 to 221 months). Tumors were located in the adrenal gland in 11 (bilaterally in 4) and extra-adrenally in 4. Localized disease occurred in 14 patients and regional disease in one. Only one patient was associated with von Hippel Lindau syndrome. Adrenalectomy or total excision of extra adrenal tumor was performed. Four patients (26.7%) recurred after the first operation (at 2 yr 9 months to 14 yr) and regional disease recurred in one patient three times. Early diagnosis, surgical excision, and long-term follow up are most important for the appropriate treatment of childhood pheochromocytoma.

BACKGROUND/PURPOSE: Undifferentiated (embryonal) sarcoma of the liver (USL) is a rare malignancy found in older children, and the most appropriate treatment strategy has been controversial. The authors report the tumor's clinical characteristics and the results of management in 6 children and recommend the best treatment plans based on these findings. METHODS: Six USL pathologically verified at Seoul National University Children's Hospital between 1990 and 2000 were reviewed retrospectively. RESULTS: The mean age at diagnosis of USL was 10.3 years (range, 7 to 13 years). There were 2 girls and 4 boys; 5 of 6 children presented with large abdominal mass, one with weight loss. Tumors ranged in size from 8.5 x 9.0 cm to 15.0 x 15.0 cm. Location of the tumor varied from right lobe in 4 to left lobe in one, and both lobes in one. Three children underwent primary complete resection without preoperative chemotherapy. Partial resection of the tumor was done in one child because of encasing inferior vena cava and hepatic vein. However, complete resection was possible at second-look operation after chemotherapy. Two children underwent complete resection after chemotherapy. Preoperative chemotherapy allowed successful resection of 3 USL, which were initially considered unresectable. Postoperative recovery for all children was uneventful. Chemotherapy according to the the Third Intergroup Rhabdomyosarcoma Study (IRS III) was administered to all except one child who refused further postoperative chemotherapy after having had severe complications during the first cycle of chemotherapy. One child with partial resection died of sepsis at 22 months after diagnosis during postoperative chemotherapy after complete surgical removal of the tumor. Five children are alive without recurrence at 40, 45, 48, 60, and 122 months, respectively, after diagnosis. CONCLUSION: The combined therapy of surgery and chemotherapy in USL can improve the prognosis.
