It is well known that NERD(Non-erosive gastroesophageal reflux disease) is a well known esophageal disease. Symptoms of NERD may be divided into two classes. Important symptoms are acid regurgitation and heartburn. Secondary symptoms are noncardiac chest pain, dysphagia, chronic coughing, hoarseness, sore throat, globus, halitosis, epigastric pain or discomfort and abdominal pain or discomfort related to bowel movement. The relationship between NERD and Tan-San(呑酸) is complex. But the most common symptoms of NERD are acid regurgitation and heartburn. These symptoms arc similar to Tan-San and can be treated with oriental medical herb and acupuncture. Ljintang-Gamibang(二陳湯加味方) mentioned in the Donguibogam(東醫寶鑑) is one of these oriental medical herbs. Therefore, this comparative study between first medical examination and end of medical treatment with Ljintang-Gamibang and acupuncture was made. The clinical progress of NERD was investigated. After treatment, all seven patients showed improvement in all symptoms associated with NERD, including general condition. The results of this study suggest that Ljintang-Gamibang and acupuncture are an effective treatment for NERD and progressive research to develop a practical treatment of NERD are needed.

Purpose: Gastric delta cells (D-cells), which are somatostatin-secreting cells, are the main paracrine inhibitor of acid secretion. The number of D-cells was studied in children presenting with upper gastrointestinal (UGI) disease. Methods: We retrospectively investigated the number of D-cells in the gastric body and antrum through immunofluorescence examinations according to symptoms, endoscopic findings, and Helicobacter pylori infection in 75 children who visited Hanyang University Hospital Pediatrics. Results: The mean patient age was 12.2±3.3 years. The male-to-female ratio was 1:1.4. The mean D-cell number per high-power field in the antrum and body was 20.5 and 12 in children with substernal pain, 18.3 and 10.3 in vomiting, 22.3 and 6 in diarrhea, and 9.3 and 6 in abdominal pain, respectively (p>0.05). According to endoscopic findings, the mean D-cell number in the antrum and body was 14.3 and 6 with gastritis, 14 and 9.3 with reflux esophagitis, 16.7 and 8.7 with duodeno-gastric reflux, 19.3 and 12.7 with gastric ulcer, 16 and 13.7 with duodenitis, and 12.3 and 4 with duodenal ulcer, respectively (p>0.05). The D-cell number in the gastric body was 2.7 and 8.7 in children with current H. pylori infection and non-infected children, respectively (p=0.01), while those in the antrum were 15.5 and 14, respectively, with no statistical significance. Conclusion: The D-cell number was lower in the gastric body of children with current H. pylori infection. Further studies concerning peptide-secreting cells with a control group would provide information about the pathogenic pathways of UGI disorder.

Variable systemic diseases affect larynx and vocal fold and result in voice change. Asthma and chronic obstructive pulmonary disease make increase of intra-abdomimal pressure followed by reflux of gastric acid, which stimulate vagal-bronchopulomary reflex aggravating cough and respiratory disturbance. Fungal laryngitis in the general population is extremely rare, but can occur in immunocompromised AIDS patients. Although, initially, empirical antifungal therapy for candidiasis is often given without biopsy, diagnostic direct laryngoscopy and biopsy is imperative if a substantial clinical response is not rapidly achieved. In the highly active anti-retroviral therapy era, HIV-positive patients are living longer and are at higher risk for developing non-AIDS-defining malignancies. The incidence of head and neck cancer (HNC) which is related with human papilloma virus infection has increased. The survival is significantly lower among the AIDS-HNC patients with CD4 counts ${\leq}200cells/{\mu}L$. Rheumatoid arthritis (RA) cause voice disturbance by developing cricoarytenoid joints fixation or nodule on vocal fold. Post-menopausal voice disorder (PMVD) is caused by decreased secretion of estrogen-progesterone resulting in decrease of fundamental frequency (F0). Hormonal replacement therapy is helpful to reduce F0 decrease. RA and PMVD result in slight voice change, but it could crucial in professional voice user.

Purpose : We evaluated the occurrence of renal scarring in children with unilateral vesicoureteral reflux(VUR), and the relationships between renal scar formation and risk factors such as VUR, duration of fever, acute-phase reactant, age, and sex. Methods : We retrospectively analyzed the data of 35 children newly diagnosed with unilateral vesicoureteral reflux after urinary tract infection(UTI) in Wallace Memorial Baptist Hospital between January 1996 and December 2004. Ultrasonography, Erythrocyte sedimentation rate(ESR), and C-reactive protein(CRP) were performed initially. Voiding cystourethrography(VCUG) was performed 1 to 3 weeks after treatment with UTI. $^{99m}Tc$-dimercaptosuccinic acid(DMSA) scan was performed 4 to 6 months after treatment. Results : Scintigraphic renal damage was present in 29 percent of the refluxing and in 3 percent of the nonrefluxing kidneys(P<0.05). The severity of VUR was significantly correlated with renal scar formation(P<0.05). The duration of fever before treatmen($5.0{\pm}1.3$ vs $2.6{\pm}1.3$) and prolonged fever of over 5 days were significantly different between renal scar group and non-renal scar group(P<0.05). ESR($56.3{\pm}23.8$ vs $27.9{\pm}18.1mm/hr$, P<0.05) and CRP($12.8{\pm}7.3$ vs $3.9{\pm}3.8mg/dL$, P<0.05) at the diagnosis of UTI in the renal scar group were higher, compared to those of the non-renal scar group. There were no significant differences in age and sex between the two groups. Conclusion : The presence and grade of VUR, the duration of fever before treatment, prolonged fever over 5 days, ESR, and CRP were risk factors for renal scarring, irrespective of age and sex. Diagnosis and management of VUR, in children with UTI, is important to prevent renal scars.

Purpose : The aim of this study was evaluating the efficacy of endoscopic $Deflux^{(R)}$ submucosal injection in children with primary vesicoureteral reflux (VUR). Methods : Retrospective analysis of medical record was conducted on 38 children (59 ureters) who underwent endoscopic $Deflux^{(R)}$ injection due to primary VUR. Data were collected from March 2000 to February 2006. Mean infused amount of $Deflux^{(R)}$ was 0.77 cc. After $Deflux^{(R)}$ injection, patients were reassessed by voiding cystourethrogram (VCUG) 6 months later. Results : The success rate of endoscopic $Deflux^{(R)}$ submucosal injection 6 months later by VCUG was 100% for grade 1 VUR, 87.5% for grade 2, 60% for grade 3, 26.6% for grade 4, 16.6% for grade 5, respectively and there was negatively significant correlation between success rate and grade of VUR (P<.01). Degree of improvement of VUR by endoscopic $Deflux^{(R)}$ submucosal injection was not related to age at diagnosis, time to operation, existence of voiding dysfunction or constipation and infused amount of $Deflux^{(R)}$. However, group with anticholinergics medication had significantly lower success rate than non-medication group (P<0.047). Conclusion : Endoscopic $Deflux^{(R)}$ submucosal injection is effective therapy in patient with primary VUR, especially low grade VUR. It can be not only a useful substitute for prophylaxis with antibiotics, but also an effective management prior to ureteroneocystostomy in children with primary VUR.

Purpose : Acute pyelonephritis in children may result in permanant renal damage which later in life may lead to hypertension and renal failure. The purpose of this study was to evaluate the factors that might be useful for predicting the development of renal scar in children with urinary tract infection(UTI). Methods : We retrospectively reviewed 442 patients with UTI who were admitted to the Department of Pediatrics of Chonbuk National University Hospital, during the period from April 1992 to March 2002. The patients were divided into two groups according to the presence of renal scar on the follow-up DMSA renal scan, and we compared the factors associated with renal scarring between the two groups. Results : There were no significant differences in sex, causative organism and acute phase reactants between the groups with and without renal scar. The age at diagnosis was significantly higher in the renal scar group compared to that without scar. Of the 60 patients with renal scar, 78% had vesicoureteral reflux(VUR), but 13% of patients without scar had VUR. Furthermore, the severity of VUR was significantly correlated with renal scar formation. 53% showed multiple cortical defects on the initial DMSA renal scan, compared to 32% in the non-scar group. In addition, 76% of patients showing multiple cortical defects on the initial DMSA renal scan with VUR had renal scar. Conclusion : The presence and grade of VUR, and findings on the initial DMSA renal scan would contribute to predict risk of renal scar formation in children with UTI.

Purpose: The American Academy of Pediatrics provides guidelines for managing febrile urinary tract infection (UTI) in infants and children 2-24 months old, but little guidance is offered regarding UTIs in those younger than 8 weeks of age. The definition of UTI is unclear and whether to proceed with micturating cystourethrography (MCUG) or $^{99m}$technetium-dimercaptosuccinic acid (DMSA) scintigraphy scan in this age group is controversial. Methods: We retrospectively analyzed 29 neonates and infants younger than 2 months of age who underwent late DMSA scans 9 months following the first episode of febrile or symptomatic UTI between July 2009 and June 2016. Results: In total, 192 children aged 0-24 months underwent ultrasound and DMSA scans (MCUG in 174/192). Neonates and infants younger than 2 months of age were significantly less likely to develop fever, and had a lower fever peak, shorter duration of fever before admission and after starting antibiotics, longer hospitalization period, lower C-reactive protein, and greater incidence of nonEscherichia coli infection. There was no difference in pyuria response at diagnosis. The prevalence rates of an ultrasound abnormality (28%), vesicoureteral reflux (28%), UTI recurrence (38%), and renal scarring (10%) in infants younger than 8 weeks of age were similar to those in children 2-24 months old. Conclusion: Neonates and infants younger than 2 months of age with UTI warrant special consideration because the fever response used for diagnosis in older children may be absent or blunted. Clinical guideline is needed for the diagnosis and management of UTI in this age group.

Green coffee beans (CB, Indonesian Mandheling) were fermented with three kinds of mushrooms (Phellinus linteus, PL; Hericium erinaceum, HE; Ganoderma lucidum, GL) or two kinds of mycelia from molds (Monascus purpureus, MP; Monascus ruber, MR) using solid-state culture to enhance physiological activity. After the roasting of fermented green coffee beans, roasted coffees were extracted with a hot-water decoction or 95% ethanol reflux. Yields from hot water extracts (HW, 17.7~25.3%) were higher than those from ethanolic extracts (EE, 9.5~12.2%). Hot-water extracts of roasted coffees from green coffee beans fermented with two molds (MP-CB-HW and MR-CB-HW) showed higher total polyphenols, flavonoids, and DPPH free radical scavenging activity than roasted coffees from non-fermented (CB-HW) or fermented green coffee beans with the three mycelia from mushrooms. MR-CB-HW also had the most potent macrophage stimulating and mitogenic activity (1.32 and 1.40-fold of CB-HW, respectively). In addition, MP-CB-EE and MR-CB-EE did not show any cytotoxicity to the RAW 264.7 cell at a concentration of $100{\mu}g/mL$, and these extracts significantly inhibited nitric oxide (NO) production from the LPS-stimulated RAW 264.7 cell line (38.6 and 37.0% of the LPS-treated group). Meanwhile, the chlorogenic acid concentrations of MP-CB-HW or MR-CB-HW highly increased (to 76.21 or $76.73{\mu}g/mL$, respectively), but caffeine concentrations were not affected by solid-state fermentation. In conclusion, the physiological activities of roasted coffees were enhanced by the solid-state culture of green coffee beans with M. purpureus or M. ruber, suggesting that these roasted coffees could possibly serve industrial applications as functional coffee beverages.
