Purpose: To assess parent perspectives of the current and potential future tests for their child with inflammatory bowel disease (IBD). Methods: New Zealand parents of a child with IBD were invited to complete an anonymous online survey. Experiences relating to their child's blood or faecal tests, medical imaging (abdominal ultrasound [US], abdominal computerised tomography [CT] and magnetic resonance enterography) and colonoscopy were collected. Perceived attitudes to potential future testing of urine, saliva, and breath, were sought. Results: Twenty-eight parents, 93% female completed the survey, and 86% were aged between 35 and 54 years. Baseline information was provided by parents for 27 of 28 children, 70.3% had Crohn's disease with a mean disease duration of 2.67 years. Blood tests were the most requested and completed tests, while CT was the least ordered and most refused test. Colonoscopy was rated as the least comfortable and generated the most worry. Explanation of test significantly improved parent's levels of understanding when their child had blood, faecal, imaging (US) or colonoscopy tests. Providing an explanation, test invasiveness and the impact of the blood results may have on their child's treatment significantly improved parents' comfort levels. However, explanation of colonoscopy generated a significant parental concerns. Saliva, urine and blood tests were chosen as the most preferred disease monitoring tests. Conclusion: Parents preferred any tests less invasive than colonoscopy for monitoring their child's IBD. Although providing explanation of their child's tests enhanced parents' understanding, it can also affect parents' levels of concern and comfort.

Smoking damages nonsmoker's health who have been exposed to passive smoking as well as smoker's own health. Passive smoking can cause serious health damage to particular groups, such as the old aged, children and pregnant women. The purpose of this study is to investigate the relationship between nicotine concentrations in environmental tobacco smoke (ETS) and urinary cotinine concentrations of nonsmokers exposed to ETS, and to provide basic information related to health risk assessment. The results of this study were summarized as follows: 1. When 180 cigarrette were smoked during S hours (high concentrations exposure) in 132 m$^3$chamber, mean concentrations of nicotine in ETS showed 263.52 $\mu\textrm{g}$/m$^3$${\pm}$51.93. When 45 cigarretts were smoked (low concentrations exposure), it was 69.43${\pm}$8.96 $\mu\textrm{g}$/m$^3$. 2. The urinary cotinine concentrations of each times (0, 2.5, 5, 17 and 24 hours) in nonsmokers ranged from 0.27∼12.52 ng/ml in high concentrations exposure and 0.22∼2.28 ng/ml in low concentrations exposure. Mean while the total urinary cotinine concentrations during 24 hours ranged from 11.62∼31.65 ng/ml in high concentrations exposure and 3.45∼5.64 ng/ml in low concentrations exposure. 3. The correlation equation and coefficient between cotinine concentrations in nonsmokers' urine (y) and nicotine concentrations in ETS (x) was y=0.421+0.0171x and 0:875 (p<0.01) respectively, 4. The quantity of nonsmokers' smoking exposure by passive smoking can be assumed as based on the estimation of nicotine concentrations in ETS by measuring cotinine concentrations of nonsmokers' urine.

Purpose : To analyse the results of the renal biopsies and the clinical diagnoses of patients who had undergone percutaneous kidney biopsies in the department of pediatrics at Kyunghee University Hospital for 22 years from 1984 to 2005. Methods : We retrospectively reviewed the medical records of 1559 patients and analyzed the chief complaints that led to a renal biopsy, age, sex, histopathologic findings and diagnosis. Routine kidney biopsies were performed by automated gun biopsy guided by real time ultrasonography. The diagnoses were made based on the specimen's light microscopy, immunofluorescence microscopy and electron microscopy findings and clinical symptoms and signs. Results : The mean age of the patients was 10 years with the male to female ratio being 1.3:1. The chief complaints that led to a renal biopsy included hematuria only(753 cases, 48.3%), proteinuria only(125 cases, 8.0%) and hematuria combined with proteinuria(537 cases, 34.4%). The most frequent histopathological finding was primary glomerular disease(75.4%) which included IgA nephropathy(30.1%) and mesangial proliferative glomerulonephritis(27.6 %). Systemic disease comprised 11.4% which included Henoch-$Sch\ddot{o}nlein$ nephritis(10.5%) and lupus nephritis(0.8%). Alport syndrome was found in 1.1% of cases which was attributed to hereditary causes. 628 children(40.3%) visited the clinic due to abnormal school urine screening abnormalities and among these, 237 children had mesangial proliferative glomerulonephritis and 234 children who had IgA nephropathy were managed thereafter. Conclusion : IgA nephropathy and mesangial proliferative glomerulonephritis were the two major forms of primary glomerulonephritis found in Korean children who had kidney biopsies from 1984 to 2005.

Schistosomiasis is prevalent in Nigeria, and the foremost pathogen is Schistosoma haematobium, which affects about 29 million people. Single dose of the drug praziquantel is often recommended for treatment but the efficacy has not been documented in certain regions. Therefore, this study was designed to assess the impact of single dose praziquantel treatment on S. haematobium infection among school children in an endemic community of South-Western Nigeria. Urine samples were collected from 434 school children and 10 ml was filtered through Nucleopore filter paper before examination for egg outputs by microscopy. The prevalence was 24.9% at pre-treatment. There was no statistically significant difference for the prevalence of infection between males (14.7%) and females (10.2%), although the mean egg count for the females (9.87) was significantly more (P<0.05) than the males (6.06). At 6 and 12 months post-treatment there was 74.4% and 86.4% reduction in the mean egg count, respectively. Interestingly, an increased prevalence of infection from 2.1% at 6 months to 7.7% at 12 months post-treatment was observed, nonetheless the mean egg count was reduced to 0.27 at 12th month from 1.98 at 6 months post-treatment. Resurgence in the prevalence rate between 6 and 12 months post-treatment with praziquantel is herein reported and the need for a follow-up treatment in endemic areas for adequate impact on schistosomiasis control is discussed.

Purpose: The aim of this study is to investigate the change in incidence and clinical characteristics of acute poststreptococcal glomerulonephritis (APSGN) through a single center's experience. Methods: We retrospectively analyzed the medical records of 53 children who were diagnosed with glomerular nephritis at National Health Insurance Corporation Ilsan Hospital between March 2000 and December 2009. Twenty-six of 53 patients falled to meet the dragnostic criteria of APSGN and were excluded. Chief complaints, physical examinations, urinalysis, urine culture, laboratory results, chest x-ray, and clinical manifestations were all retrieved from the remaining 27 patients. Results: The incidence of APSGN by age was highest in children between six to seven years of age, with similar distributions in both genders, and seasonal incidence was higher from November to February when compared to other months, which was similar to the previously reported studies. However, the annual number of APSGN patients did not show a significant decrease from 2000 to 2009. The incidences of edema and hypertension were 59.3% and 48.1% respectively, suggesting lower incidences than those from previous studies. Six patients (22.2%) experienced hematuria for more than 6 months. Hypertensive encephalopathy, one of APSGN critical complications occurred in one patient but resolved with conservative treatment. Conclusion: Our study shows that APSGN still occur as a common renal disease but the disease severity seems to decrease with milder clinical manifestations and less complications compared to past studies.

Purpose : Efforts to predict the clinicopathological outcome of IgA nephropathy have been made but have yielded conflicting results and have not helped in deciding the appropriate timing of the renal biopsy. In this study, we reviewed the predictive factors of clinicopathological outcome for finding out the criteria of renal biopsy timing of IgA nephropathy. Methods : Forty children diagnosed with biopsy proven IgA nephropathy at Wonju Christian Hospital were studied retrospectively, based on medical records. Results : Among 39 patients, 2 children progressed to higher serum creatinine level. One of them reached to the end stage renal disease within 2 year 7 months. According to WHO histopathological classification, there were 15 cases of class I, 14 cases of class II, 7 cases of class III, and 3 cases of class IV. In the mild histological classes(class I, II), gross hematuria was shown in 23 out of 29 children(P=0.02). In the severe histological classes(class III, IV), gross hematuria was noted in 4 out of 10(P>0.05). The tubulointerstitial changes were grade 1 in 24 cases, grade 2 in 4 cases, grade 3 in 8 cases, and grade 4 in 3 cases. With an increase in the tubulointerstitial grade, the 24 hour urine protein/albumin ratio increased. Serum creatinine less than 0.79 mg/dL could predict the lower grade(grade 1 and 2) of tubulointerstitial changes. But serum creatinine greater than 1.13 mg/dL could predict the higher grade(grade 3 and 4) of tubulointerstitial changes. In children with gross hematuria(n=27), serum creatinine was lower(0.78 vs 1.09 mg/dL, P=0.027), serum IgA was higher(316.3 vs 198.8 mg/dL), and the cases of lower WHO classification(I and II) were more common(23 vs 4, P=0.029) than the children with microscopic hematuria. Conclusion : Serum creatinine less than 0.79 mg/dL, macroscopic hematuria, and higher 24 hour urine protein/albumin ratio would predict the lower grade glomerulo tubulointerstitial lesion in IgA nephropathy and could be used as the criteria delaying the renal biopsy.

The purpose of this study was to find out the prevalence of the urinary incontinence and it's relating factors in women. The target population is 327 community dwelling women in the age of 30-70 years old at 6 cities in Korea. The data were collected from August, 1996 to December. 1996 with interview using structured questionaire composing of items of general characteristics, obstetric characteristics, disease characteristics, situation of experiencing urinary incontinence, discomfort due to urinary incontinence, and depression. The data were analysed with $SPSS/PC^+$ program, T-test, $x^2$ test, and ANOVA test. The results obtained from this study were as follows : 1) The prevalence of urinary incontinence in women is 37.7%(130/327). 2) The mean duration of experiencing the urinary incontinence was 75.9 months and the 60% of the respondents experienced a few frequency of urinary incontinence and the most common amount of urinary incontinence(91.5%) was somewhat small expressed as 'wetting their clothes'. 3) The common factors related to the urinary incontinence were coughing, sneezing, laughing aloudly, and the activities of need for hurry. 4) The most common situations of discomforts associated with urinary incontinence were having long journey, exercise, playing, and social meeting. 5) The incidence of urinary incontinence was significantly higher in woman who had more children, older age of last delivery, more vaginal delivaries, and less c-section. 6) The incidence of urinary incontinence was not affected with the disease characteristics of the respondents, however it was higher when the women had the physical problems of constipation, abdominal laparatomy and episode of urinary catheterization than who had not. 7) The most common symptom of urinary incontinence was the frequent urine(43.1%), and the next was the urgent urine(12.3), delayed urine(9.2%). 8) 90.7% of the epsodic urinary incontinence were not treated at al, however, they wanted to try the herb medicine(41.5%), Kegel exercise(27.7%), and biofeedback(10.0%). 9) The level of Depression in the group of urinary incontinence was higher than that of non incontinence group significantly. In conclusion, as urinary incontinence in women proved severe health problem, health care providers need to develop and provide nursing intervention of urinary incontinence such as pelvic muscle exercise with bio-feedback and psychological care.

Propionic acidemia (PA) is an inherited autosomal recessive disorder, due to the deficiency of propionyl-CoA carboxylase (PCC). PCC is the enzyme which catalyzes the conversion of propionyl-CoA to D-methylmalonyl-CoA, and it is critical for the metabolism of amino acids, odd-chain fatty acids, and side chains of cholesterol. The clinical manifestations present mostly at the neonatal period with life-threatening metabolic acidosis and hyperammonemia. Here, we described a case of a 16-year-old Korean boy with late-onset PA who presented with embolic cerebral infarction due to dilated cardiomyopathy (DCMP) with left ventricular noncompaction. And he has family history of sudden cardiac death, so we performed metabolic screening and genetic tests. Elevated levels of 3-hydroxypropionic acid, methylcitric acid and propionylglycerine were detected in urine. Plasma acylcarnitine profile showed elevated propionylcarnitine (C3). Diagnosis of PA was confirmed by genetic analysis, which revealed compound heterozygous mutations, c.[1151T>G] (p.[Phe384Cys]) and c.[1228C>T] (p.[Arg410Trp]) in PCCB gene. His heart function is in improving state and the results of biochemical analysis are stable with heart failure medication and metabolic managements. We present a case of patient without episodes of metabolic decompensation who manifests DCMP as the first symptom of PA.

Backgrounds: Sticking warm and hot herbs to acupoint in Dog-Days where the strongest Yangqi takes place, Acupoint sticking in Dog-Days is one of Oriental medical treatment to cure winter diseases in the summer. This treatment is widespread in China and Taiwan, and is becoming popular in South Korea nowadays. Objectives: The research has been conducted to evaluate the influencial factors and efficacy in Acupoint sticking in Dog-Days. Methods: We visited one kindergarten in Dog-Days of 2010, and attached pills which are made of Sinapis Semen(白芥子), Corydalis Tuber(玄胡索), Asari Herba Cum Radix(細辛), Juice of Zingiber Officinale(薑汁) to BL-13(肺兪), BL-15(心兪), BL-17(膈兪) of 56 children for 4-6 hours(34 boys, 22 girls, $52.64{\pm}16.85$ months, 19-78 months). Exacerbating effect or non-significant changes in respiratory symptoms before and after the treatment were ified.. The influentialfactors of efficacy were analyzed by Pearson's $x^2$-test and Fisher's exact test. In addition, the efficacy and satisfaction among once, twice, and three times treatment groups were verified by ANOVA. Results: 27 children (48.2%) were effective, but efficacy felt by parents is 45 cases (80.4%). Sex, perspiration, stool, urine, sleep, cold of hands and feet, cold sensitivity, and frequency of Acupoint sticking in Dog-Days has no relation to efficacy(p>0.05). However, the efficacy is poor in 1 and 2 age(p=0.030). Difference among efficacy of once, twice, and three times treatment groups is not significant(p=0.069), whereas there are linear association in frequency of Acupoint sticking in Dog-Days and efficacy(p=0.030). 36 parents (64.3%) are satisfied with Acupoint sticking in Dog-Days, and we observed significant difference among once, twice, three times treatment groups(p=0.041). 19 parents (33.9%) had been known about Acupoint sticking in Dog-Days, but 53 parents (94.6%) wanted repetition, and 41 parents (73.2%) intended to recommend it to acquaintance. Side effects are minor itching in two cases. Twenty seven participants showed positive effect, and forty five people (80.4%) felt beneficial. Sex, perspiration, stool, urine, sleep, cold hands and feet, sensitivity in cold, and frequency of Acupoint sticking in Dog-Days has no relation to the efficacy(p>0.05). Though the efficacy was poor in one and two year old infants, it was linearly correlated with the frequency count and responses from the treatment (p=0.030). Thirty six participants (64.3%) satisfied with the treatment, and so did the first, second, and third participant groups (p=0.041). Even though, only nineteen participants (33.9%) were familiar with Acupoint sticking in Dog-Days, fifty three participants (94.6%) preferred to repeat the treatment, and 41 parents were preferable to recommend the treatment to others. Side effects of minor itching has been reported in a couple cases. Conclusions: Acupoint sticking in Dog-Days is effective in children older than three year old. The effect would be greater when going through the treatment three times. Based on significant satisfaction, intention of repetition and recommendation, strong promotion on Dog-Days are needed to make a better use of Acupoint sticking in Dog-Days for the effective treatment.

Purpose : Our examination was designed to determine the diagnostic properties of the cutoff point for the prediction of bacteremia in febrile children less than 3 years of age. Cutoff point is the value that simultaneously maximizes both sensitivity and specificity. Methods : We conducted a retrospective study of febrile children, less than 3 years of age, who clinically have no identifiable source of fever. Peripheral blood leukocyte count(WBC), absolute neutrophil count(ANC), erythrocyte sedimentation rate(ESR) and C-reactive protein(CRP) were measured at the same time. All patients received blood culture, urine culture and/or CSF culture. Bacterial infection was defined as single pathogen isolated from the CSF or blood or a urinary tract infection (UTI). Patients were dichotomized into two groups : those with bacterial infection and no bacterial infection. We analyzed the characteristics of the children in the two groups. Results : Seventy-one patients(44 males; 27 females) were enrolled in the study. Twenty patients (28%) had a serious bacterial infection(twelve urinary tract infection, five bacteremia, three meningitis) and fifty-one(72%) had no serious bacterial infection. WBC, ESR and CRP were significantly different between the two groups(P<0.05). The cutoff point of WBC, ESR and CRP were $20,000/mm^3$, 30 mm/hr and 3.0 mg/dL, respectively. The sensitivity and specificity of each cutoff point were WBC(75%, 75%), ESR(79%, 68%) and CRP(83%, 77%), respectively. Conclusion : These data show the ability of predictors to identify febrile children less than 3 years of age with bacterial infection. Febrile children who reach the cutoff point must be treated intensively and those who do not reach the cutoff point can be carefully managed without administering antimicrobial agents.
