Nutritional interventions improve quality of life of caregivers of children with neurodevelopmental disorders.

Introduction: Children with neurodevelopmental disorders are at high risk for malnutrition. We aimed to investigate the impact of nutritional interventions to children with neurodevelopmental disorders and the quality of life of caregivers.Materials/Method: This is a prospective interventional study of 91 children with neurodevelopmental disorders. The children were separated into two groups: the intervention group and control group. The intervention group was selected from among children who had not been evaluated for nutrition and feeding problems by a pediatric gastroenterologist or dietician for the past one year. Children in the intervention group were called for follow-up visits and their nutritional intervention and anthropometric measurements were initiated by a pediatric gastroenterologist and dietician, at one month, three months, six months, and one year. The WHOQoL-BREF quality of life scale was completed by the caregivers of the children at baseline and at one year.Results: The intervention group had increased malnutrition (p < 0.001) and gastrointestinal system pathologies such as dysphagia (p < 0.001), constipation (p = 0.02), gastroesophageal reflux (p = 0.03) at baseline. After the nutritional intervention, 77.7% of the intervention group gained weight and 55.5% reached the target weight. The quality of life scale scores at baseline were lower among caregivers of the intervention group; however, they reached those of the control group after the nutritional intervention.Conclusion: Close multidisciplinary nutrition monitoring enables children with neurodevelopmental disorders to thrive appropriately and improves the quality of life of caregivers.

The effect of Celiac disease on cardiac functions and aortic elasticity parameters in children.

AIM: We aimed to investigate the effect of Celiac disease on myocardial functions and aortic elasticity parameters. MATERIALS AND METHODS: Thirty children with Celiac disease and 30 healthy children were enrolled in the study. Both the groups were similar in terms of age and gender. Cardiac functions of all children in the patients and control group were evaluated using conventional transthoracic echocardiography and tissue Doppler imaging. Aortic strain, distensibility, and stiffness index were calculated by M-mode echocardiography. RESULTS: The demographic findings, height, weight, and body mass index of cases were similar among two groups. No statistical difference was found between E wave velocity for conventional transthoracic echocardiography and tissue Doppler imaging measurements of the mitral valve; early diastolic flow peak velocity, A wave velocity; late diastolic flow peak velocity; and E/A ratio. Isovolumetric relaxation time and isovolumetric contraction time ratios were statistically different between the groups (p = 0.000, p = 0.000, p = 0.000). The myocardial performance index calculated according to the pulse Doppler measurement results was found to be statistically different between the groups (p = 0.000). There was no statistical difference between the groups in terms of aortic strain, distensibility, and stiffness index. CONCLUSION: In this study, both conventional transthoracic echocardiography and tissue Doppler imaging revealed the affection of the myocardial functions during systole and diastole in children with Celiac disease. Therefore, early follow-up and routine cardiac evaluation of celiac patients may be appropriate due to the increased risk of cardiac affection.

The Frequency of Lysosomal Acid Lipase Deficiency in Children With Unexplained Liver Disease.

OBJECTIVES: Evidence suggests that lysosomal acid lipase deficiency (LAL-D) is often underdiagnosed because symptoms may be nonspecific. We aimed to investigate the prevalence of LAL-D in children with unexplained liver disease and to identify demographic and clinical features with a prospective, multicenter, cross-sectional study. METHODS: Patients (aged 3 months-18 years) who had unexplained transaminase elevation, unexplained hepatomegaly or hepatosplenomegaly, obesity-unrelated liver steatosis, biopsy-proven cryptogenic fibrosis and cirrhosis, or liver transplantation for cryptogenic cirrhosis were enrolled. A Web-based electronic data collection system was used. LAL activity (nmol/punch/h) was measured using the dried blood spot method and classified as LAL-D (<0.02), intermediate (0.02-0.37) or normal (> 0.37). A second dried blood spot sample was obtained from patients with intermediate LAL activity for confirmation of the result. RESULTS: A total of 810 children (median age 5.6 years) from 795 families were enrolled. The reasons for enrollment were unexplained transaminase elevation (62%), unexplained organomegaly (45%), obesity-unrelated liver steatosis (26%), cryptogenic fibrosis and cirrhosis (6%), and liver transplantation for cryptogenic cirrhosis (<1%). LAL activity was normal in 634 (78%) and intermediate in 174 (21%) patients. LAL-D was identified in 2 siblings aged 15 and 6 years born to unrelated parents. Dyslipidemia, liver steatosis, and mild increase in aminotransferases were common features in these patients. Moreover, the 15-year-old patient showed growth failure and microvesicular steatosis, portal inflammation, and bridging fibrosis in the liver biopsy. Based on 795 families, 2 siblings in the same family were identified as LAL-D cases, making the prevalence of LAL-D in this study population, 0.1% (0.125%-0.606%). In the repeated measurement (76/174), LAL activity remained at the intermediate level in 38 patients. CONCLUSIONS: Overall, the frequency of LAL-D patients in this study (0.1%) suggests that LAL-D seems to be rare even in the selected high-risk population.

Measurement of Rectal Diameter and Anterior Wall Thickness by Ultrasonography in Children with Chronic Constipation.

BACKGROUND: Measurement of rectal diameter by ultrasonography helps the clinician in the diagnosis of chronic constipation in children for whom rectal examination cannot be performed. The aim of the study is to determine the rectal diameter and anterior wall thickness values in constipated and healthy children and to evaluate the feasibility of ultrasonography in the diagnosis of functional constipation in children who refuse digital rectal examination. METHODS: One hundred forty constipated and 164 healthy children participated in the study. All patients were divided into 4 subgroups according to their ages (≤3 years [group I], 3.1-6 years [group II], 6.1-12 years [group III], and >12 years [group IV]) and were referred to the radiology department. The measurement was made from above the symphysis pubis, under the ischial spine, and at the bladder neck. Anterior wall thickness measurement was performed. The measurements were recorded according to the presence or absence of fecal mass in the rectum. RESULTS: Constipated children with fecal mass positive group III was found to have significant difference in all of the planes in rectal diameter measurement. Rectum anterior wall thickness measurement was found to be higher in constipated patients with fecal mass (+) compared to the control. Its measurements in constipated patients in group II, group III, and group IV with no fecal mass were found to be statistically higher than the control group. CONCLUSION: The measurement of rectal diameter and anterior wall thickness by ultrasonography as a noninvasive method was per formed in children who did not want the digital rectal examination, and it may be useful in the diagnosis of constipation.

Diagnostic yield of upper gastrointestinal endoscopy in the evaluation of iron deficiency anemia in older children and adolescents.

Iron deficiency anemia (IDA) is frequent in childhood. Inadequate nutrition and gastrointestinal malabsorption are the frequent causes of IDA in children. But reduced iron absorption and insidious blood loss from the gastrointestinal tract has been identified as the most frequent causes of IDA in older children and adolescents. Therefore the authors evaluated the frequency and etiologies of the upper gastrointestinal system pathologies causing IDA in older pediatric population. Patients with known hematological or chronic diseases, heavy menstrual flow, and obvious blood loss were excluded from the study. Forty-four children between the ages of 9.5 and 17.5 years and diagnosed with IDA were enrolled. They underwent upper gastrointestinal endoscopy and biopsy from esophagus, stomach, and duodenum. Mean age and hemoglobin (Hb) levels of study group (32 boys, and 12 girls) were 14.6 ± 2.0 years and 7.9 ± 1.8 g/dL, respectively. Only 1 patient had a positive serology testing with anti-tissue transglutaminase and small bowel biopsy correlating with celiac disease. Endoscopy revealed abnormal findings in 25 (56.8%) patients (21 endoscopic antral gastritis, 2 active duodenal ulcers, and 2 duodenal polyps). Helicobacter pylori (HP) infection was identified by using antral histopathological evaluation in 19 of 44 children (43.2%). In 2 of duodenal samples, one patient had celiac disease, and the other one was diagnosed as giardiasis. In conclusion, there are different etiologies resulting in IDA in older children and adolescents. When older children and adolescents are found to have iron deficiency, HP infection and other gastrointestinal pathologies should be ruled out before iron deficiency treatment.

Familial Mediterranean Fever Mutation Analysis in Pediatric Patients With Inflammatory Bowel Disease: A Multicenter Study.

BACKGROUND: The aim of the study was to evaluate familial Mediterranean fever (FMF) mutation analysis in pediatric patients with inflammatory bowel disease (IBD). The relation between MEFV mutations and chronic inflammatory diseases has been reported previously. METHODS: Children with IBD (334 ulcerative colitis (UC), 224 Crohn's disease (CD), 39 indeterminate colitis (IC)) were tested for FMF mutations in this multicenter study. The distribution of mutations according to disease type, histopathological findings, and disease activity indexes was determined. RESULTS: A total of 597 children (mean age: 10.8 ± 4.6 years, M/F: 1.05) with IBD were included in the study. In this study, 41.9% of the patients had FMF mutations. E148Q was the most common mutation in UC and CD, and M694V in IC (30.5%, 34.5%, 47.1%, respectively). There was a significant difference in terms of endoscopic and histopathological findings according to mutation types (homozygous/ heterozygous) in patients with UC (P < .05). There was a statistically significant difference between colonoscopy findings in patients with or without mutations (P = .031, P = .045, respectively). The patients with UC who had mutations had lower Pediatric Ulcerative Colitis Activity Index (PUCAI) scores than the patients without mutations (P = .007). CONCLUSION: Although FMF mutations are unrelated to CD patients, but observed in UC patients with low PUCAI scores, it was established that mutations do not have a high impact on inflammatory response and clinical outcome of the disease.

Metabolic predictors for early identification of fatty liver using doppler and B-mode ultrasonography in overweight and obese adolescents.

THE AIMS OF OUR STUDY WERE: (1) to evaluate the frequency of asymptomatic fatty liver disease (FLD) using both Doppler and B-mode ultrasound (US) in overweight and obese adolescents; (2) to compare metabolic findings of fatty liver (FL) assessed by two methods; and (3) to evaluate metabolic predictors of FL shown by these methods. Fifty-nine overweight and obese adolescents aged between 9.0 and 17.0 years and 41 non-obese healthy adolescents were included in this study. B-mode and right hepatic vein Doppler ultrasonography (US) were performed and anthropometric indices, lipid profiles, and adiponectin levels were evaluated in all adolescents. HDL-C levels were significantly lower in patients with FL detected by Doppler US compared to patients without FL (p < 0.05). HDL-C levels were inversely correlated with presence of FL assessed by two methods (r = -0.285, p = 0.004; r = -0.328, p = 0.001, respectively) and adiponectin levels were correlated with presence of FL only detected by B-mode US (r = -0.263, p = 0.008). Adiponectin levels were significantly lower in patients with FL than those without FL assessed by B-Mode US (p = 0.049). Multiple regression analysis revealed that HDL-C levels was the most important predictor of FL assessed by Doppler US (p = 0.027), while body mass index was the determinant of FL assessed by two methods (p < 0.001) in asymptomatic overweight and obese adolescents. It was found that FLD, identified by both B-mode and Doppler US, is seen frequently in asymptomatic overweight and obese adolescents. Elevated BMI is associated with increased risk of FL assessed by two ultrasonographic methods. When using Doppler US, low HDL-C levels can be used as a good predictor for presence of FLD in overweight and obese adolescents.

Diagnostic value of stool antigen and antibody tests for Helicobacter pylori infection in Turkish children with upper gastrointestinal complaints before and after eradication.

The aim of this study was to evaluate the diagnostic value of Helicobacter pylori stool antigen (HpSA) and serologic tests before and after eradication therapy for H. pylori in Turkish children in our region with upper gastrointestinal complaints. In this study, 87 children with upper gastrointestinal complaints and 95 children with various symptoms without gastrointestinal complaints were enrolled. H. pylori infection was detected by urea breath test (UBT). HpSA and H. pylori immunoglobulin G (HpIgG) tests were applied to all the children. Eradication treatment was given to the 34 H. pylori-positive children. The UBT was positive in 43 of 87 children (49.4%) with upper gastrointestinal complaints. The sensitivity and specificity of the HpSA in children with upper gastrointestinal complaints were 86% and 84.1%, respectively, and those for the HplgG were 76.7% and 90.9%, respectively. After eradication, the overall HpSA test sensitivity and specificity values were detected as 88.9% and 84%, respectively, and those for the HpIgG were 77.8% and 36%, respectively. The HpSA test is highly sensitive and specific for the diagnosis of H. pylori and for confirming eradication in Turkish children with upper gastrointestinal complaints. However, serology is not a reliable method for the diagnosis of H. pylori infection or for confirming eradication in children.

Is low FODMAP diet effective in children with irritable bowel syndrome?

OBJECTIVE: There is growing evidence that suggests that consumption of fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAPs) may result in some symptoms in certain patients with irritable bowel syndrome (IBS). This study aims to evaluate the efficacy of a low FODMAP diet in children with IBS by comparing it with the standard diet. METHODS: Sixty children between the ages of 6 and 18 who were diagnosed with IBS according to Rome IV criteria were included in this study. Randomly selected patients were divided into two groups as 30 patients on a low FODMAP diet and 30 patients on a general protective standard diet for the gastrointestinal tract. Patients were evaluated at the beginning, second and fourth months of the study. The data of the patients were recorded in the demographic data form. Patients were asked to score abdominal pain using the Visual Analogue Scale (VAS). The clinical status of the patient was scored by the doctor using the Clinical Global Impression Improvement (CGI-I) scale. RESULTS: There were no significant differences between groups about age, sex and symptom duration. When the pre-diet VAS scores were compared, the two groups were similar. The mean decrease in VAS score after two months of diet was 3.80±1.10 in the low FODMAP group and 2.03±1.03 in the standard group and was statistically significant. Post-dietary CGI-I score evaluation was determined to be statistically significant between the two groups. The increase in VAS scores in the fourth month was 2.97±1.10 points in the Low FODMAP group and 1.63±0.71 in the standard group, and was statistically significant. CGI-I score after the diet at the 4th month was also statistically significant between the two groups. CONCLUSION: A low FODMAP diet seems to be more effective for symptom control in IBS when compared to standard dietary advice. Further studies are needed for the unknowns that will be used in clinical practice, such as how long the diet will be continued and how effective it will be in which GIS diseases.

Should we worry about the eyes of celiac patients?

PURPOSE: In this article, we evaluate subfoveal choroidal thickness in celiac patients with respect to adherence to the gluten-free diet and nonadherence to the gluten-free diet, comparing with age and sex matched healthy controls using spectral-domain optical coherence tomography. MATERIALS AND METHODS: A case-control study among 42 celiac patients and 42 healthy participants was conducted in the Department of Pediatric Gastroenterology. Celiac patients of our policlinics compliant with spectral-domain optical coherence tomography examination enrolled in the study. Celiac patients had been asked verbally about their adherence to gluten-free diet, were evaluated according to negative or positive EmA and anti-TG2 for defining adherence, and were divided into two groups (adherence to gluten-free diet and nonadherence to gluten-free diet). RESULTS: Subfoveal choroidal thickness was thinner in EmA (+) or anti-TG2 (+) eyes than EmA(-) or anti-TG2 (-) eyes in celiac patients, but it was not statistically significant. The mean subfoveal choroidal thickness values in eyes with celiac disease, whose diagnosis time was longer than 60 months, were thinner than shorter group. Longer duration of gluten-free diet was associated with adherence difficulty and thinner choroidal thickness (r = -0.15, p = 0.34). Adherence to gluten-free diet was 88.2% for children below the age of 60 months and 57.1% for children older than 60 months. CONCLUSION: In conclusion, in addition to other extraintestinal manifestations of celiac disease, diagnosis time longer than 60 months in pediatric celiac patients, nonadherence to the gluten-free diet, and antibody positivity should be focused on during ophthalmologic examination and choroid measurement.

Coexistence of symptomatic iron-deficiency anemia and duodenal nodular lymphoid hyperplasia due to giardiasis: case report.

Iron-deficiency anemia due to iron malabsorption and duodenal nodular lymphoid hyperplasia (NLH) has been described in children with Giardia intestinalis infection. Also, symptomatic iron-deficiency anemia is rarely encountered in male adolescents. A 14-year-old boy underwent esophagogastroduodenoscopy for investigation of symptomatic iron-deficiency anemia (hemoglobin 5.8 g/dL, mean corpuscular volume 65.3 fL, serum ferritin < 1.5 ng/mL). He had a sufficient diet for iron and recurrent bouts of diarrhea without melena. At upper endoscopy, duodenal mucosa was diffusely nodular. Histopathologic evaluation of biopsy samples from the duodenum revealed infection with Giardia intestinalis. His anemia improved with metronidazole and iron treatment.

The importance of stool tests in diagnosis and follow-up of gastrointestinal disorders in children.

Stool is not just a simple waste material. Some stool tests can be easily used in primary care in the differential diagnosis of disorders such as gastrointestinal infections, malabsorption syndromes, and inflammatory bowel diseases. Stool tests can prevent unnecessary laboratory investigations. Stool analyses include microscopic examination, chemical, immunologic, and microbiologic tests. Stool samples can be examined for leukocytes, occult blood, fat, sugars (reducing substances), pH, pancreatic enzymes, alpha-1 antitrypsin, calprotectin, and infectious causes (bacteria, viruses, and parasites). Stool should also be macroscopically checked in terms of color, consistency, quantity, shape, odor, and mucus.

Clinical significance of low transaminase levels in children with inflammatory bowel disease.

BACKGROUND: Low alanine aminotransaminase (LALT) levels may be seen in patients with inflammatory bowel disease (IBD), but there has been no study about the frequency and its clinical significance. We aimed to analyze the frequency of LALT, and its clinical significance in children with IBD. METHODS: The study included the 89 patients with IBD without hepatobiliary involvement. LALT was defined as ALT levels < 5 U/L. Demographic and clinical findings and outcome of the patients with and without LALT were compared. RESULTS: LALT was found 47.1% of the patients. At initial examination, it was more common in female patients (92.3 vs. 41.3%, P < 0.001) and patients with CD (57.7 vs. 30.2%, P = 0.01). 75% of the patients with penetrating Crohn's disease (CD) had LALT (P = 0.002). Hemoglobin (10.4 ± 2.1 vs. 11.7 ± 1.9 g/dL, P = 0.01), folic acid (5.2 ± 3.3 vs. 8.6 ± 5.9 ng/mL, P = 0.02) and serum albumin levels (3.6 ± 0.8 vs. 4.7 ± 5 g/dL, P = 0.002) were significantly low in patients with LALT. LALT was associted with the disease relapse within 2 weeks in 12 of the 16 patients with LALT whereas it was seen in 16 of the 73 patients without LALT during the follow-up (75 vs. 21.9%, P < 0.001). Additionally, steroid dependency was more common in patients with LALT during the follow-up (62.5 vs. 12.3%, P < 0.001). CONCLUSIONS: LALT is common in children with IBD especially in CD and associated with low hemoglobin, albumin and folic acid levels. It may be a marker of relapse and steroid dependency.

Is Helicobacter pylori related to endothelial dysfunction during childhood?

BACKGROUND: Helicobacter pylori infection has been proposed to have a role in the development of atherosclerosis preceded by endothelial dysfunction. The aim of the present study was to determine if a relationship exists between H. pylori infection in childhood and endothelial dysfunction and level of high-sensitivity C-reactive protein (hsCRP). METHODS: Between October 2003 and November 2004, 28 subjects who were anti-H. pylori IgG-positive and 25 who were anti-H. pylori IgG-negative were included in the study. Mean ages of the H. pylori-positive and negative groups were not significantly different. Endothelial functions were evaluated on Doppler ultrasonography of the brachial artery. Percent ratio of the change in systolic diameter during hyperemic phase to the basal diameter was evaluated. Each subject's serum was tested for hsCRP, homocysteine and lipids. RESULTS: Percent ratio of the change in systolic diameters during hyperemic phase to the basal diameter was not significantly different between the H. pylori-negative and -positive groups (P > 0.29). Mean levels of hsCRP were also not significantly different (1.48 +/- 1.8 g/dL vs 2.35 +/- 3.33 g/dL; P > 0.24). Similarly, serum levels of lipids and homocysteine were not significantly different (P > 0.05 for all lipids). CONCLUSIONS: Non-invasive techniques used in the present study were not indicative of early findings of atherosclerosis in H. pylori infection during childhood. Further studies are required to evaluate the relationship between early endothelial dysfunction and H. pylori infection in children with cardiovascular risk factors.

Clinical findings, child and mother psychosocial status in functional constipation.

BACKGROUND/AIMS: Functional constipation (FC) is a common problem in childhood. In this study, we aimed to analyze the clinical and sociodemographic findings of patients with FC, parenting behaviors, and psychosocial states of children and parents. MATERIALS AND METHODS: According to the Roma III diagnosis criteria, 32 patients with FC and 31 healthy controls were included. Patients' clinical and sociodemographic data set associated with constipation was determined. Strengths and Difficulties Questionnaire was used to screen the emotional and behavioral problems in children. To evaluate the parents and family, Beck Depression Inventory, State-Trait Anxiety Inventory, Parental Attitude Research Instrument were used. RESULTS: Emotional and peer problems subscale scores, parental concerns as well as over-parenting attitude were found higher in patients. Significant difference was also observed between the groups in terms of mean score of authoritarian attitude dimensions. Attitude of hostility and rejection and marital discordance was found to be significantly high in patient families. Our study revealed a decrease in the constipation rate with the increasing education level of parents, higher rate of constipation in families with less income than expenses, and lower rate of working mothers in patients with constipation. Parents' depressive symptoms and anxiety level were determined to be considerably higher. CONCLUSION: A mother's low education level, low socioeconomic level, presence of psychological symptoms, and problems of parental attitude-primarily the authoritarian attitude-increase the risk of FC occurrence. Therefore, FC patients and their families should definitely undergo a psychosocial assessment.

Comparison of two different regimens of combined interferon-alpha2a and lamivudine therapy in children with chronic hepatitis B infection.

AIM: To evaluate the efficacy of two regimens of combined interferon-alpha2a (IFN-alpha2a) and lamivudine (3TC) therapy in childhood chronic hepatitis B. METHODS: A total of 177 patients received IFN-alpha2a, 9 million units (MU)/m2 for 6 months. In group I (112 patients, 8.7 +/- 3.5 years), 3TC (4 mg/kg/day, max 100 mg) was started simultaneously with IFN-alpha2a, in group II (65 patients, 9.6 +/- 3.8 years) 3TC was started 2 months prior to IFN-alpha2a. 3TC was continued for 6 months after antiHBe seroconversion or stopped at 24 months in nonresponders. RESULTS: Baseline alanine aminotransferase (ALT) was 134.2 +/- 34.1 and 147.0 +/- 45.3; histological activity index (HAI) was 7.4 +/- 2.7 and 7.1 +/- 2.3; and HBV DNA levels were above 2,000 pg/ml in 76% and 66% of patients in groups I and II, respectively (P > 0.005). Complete response was 55.3% and 27.6% in groups I and II, respectively (P < 0.01). AntiHBe seroconversion was higher and earlier, and HBV DNA clearance was earlier in group I (P < 0.05). HBsAg clearance was 12.5% and 4.6% and antiHBs seroconversion was 9.8% and 6.2% in groups I and II, respectively (P > 0.05). Breakthrough occurred in 17.9% and 24.6%; breakthrough times were 15.9 +/- 4.6 and 14.1 +/- 5.1 months; and relapse rates were 6.8% and none in groups I and II, respectively (P > 0.05, P > 0.05, P > 0.05). Responders had higher HAI (HAI > 6) and higher pre-treatment ALT than non-responders. CONCLUSION: Simultaneous 3TC+IFN-alpha2a yields a higher response and earlier antiHBe seroconversion and viral clearance than consecutive combined therapy. Relapse rate is low. Predictors of response are high basal ALT and high HAI scores. 3TC can be administered for 24 months without any side effect and breakthrough rate is comparable with previous studies.

Evaluation of voiding dysfunctions in children with chronic functional constipation.

There are controversial results about the role of dysfunctional bowel emptying in disorders of the urinary tract like urinary tract infection (UTI), vesicoureteral reflux (VUR) and enuresis. Constipation may cause UTI, enuresis and VUR due to the uninhibited bladder contraction. The aim of this study was to investigate the frequency of nocturnal enuresis, UTI and instability symptoms in chronic functional constipation (CFC). This study included 38 children with CFC and 31 children as the control group. Detailed past and present history of UTIs or symptoms pointing to this diagnosis, enuresis, encopresis, urgency and urge incontinence was obtained from both groups as well as the family history of UTI. Urinalysis, urine culture and stool parasite analysis as well as abdominal ultrasonography were performed on both groups. Age range of the children with CFC was 6-192 months (mean +/- standard deviation (SD) 63.5 +/- 51 months); that of the control group was 4-180 months (mean +/- SD 82 +/- 46.2 months). Frequency of UTI and urgency was significantly higher in the CFC group. However, frequencies of urge incontinence, nocturnal enuresis, and genitourinary abnormalities were not different between the two groups. In conclusion, risk of UTI and urgency is increased in CFC, but that of other voiding dysfunctions like urge incontinence do not change significantly. Therefore, we suggest that UTI and urgency should be questioned in children with CFC and vice versa.

Neonatal Cholestasis as Initial Presentation of Portosystemic Shunt: A Case Report.

Congenital intrahepatic portosystemic shunts are rare in children. Portosystemic venous malformations are characterized by extreme clinical variability. We report a full-term 33-day-old male infant presenting with neonatal jaundice. On physical examination, he had generalized icterus and the liver was palpable 3.5 cm below the right costal margin. He had no other symptoms. Laboratory tests showed AST 632 U/L, ALT 198 U/L, total bilirubin 12.1 mg/dL, conjugated bilirubin 10.2 mg/dL, alkaline phosphatase 753 U/L, GGT 47 U/L and glucose 67 U/L. Colour Doppler ultrasonography showed the left portal vein was more dilated than the right portal branch and communication with dilated left hepatic vein. There was no evidence of portal hypertension, heart failure, hepatopulmonary syndrome and encephalopathy during his hospital stay, so he was discharged from the pediatric department and his parents advised to attend monthly follow-up. Congenital portosystemic shunts are rarely observed in the childhood period.1 Depending on anatomic characteristics they may be intrahepatic or extrahepatic.2 Intrahepatic portosystemic shunts (PSS) are observed between the portal vein and hepatic vein or vena cava inferior.3, 4 Small shunts may close themselves before the age of 2 years.5 With the increase in use of imaging methods, diagnosing PSS has become easier, with an increase in the number of cases reported.6 Neonatal cholestatis is a frequent complication of PSS.1 We present a case presenting with neonatal cholestasis diagnosed with congenital intrahepatic PSS.

Coexistence of Helicobacter pylori and Intestinal Parasitosis in Children with Chronic Abdominal Pain.

OBJECTIVE: The aim of this study was to determine the incidence of coinfection with Helicobacter pylori and intestinal parasitosis in children with chronic abdominal pain (CAP) and to investigate the common risk factors in the development of both infections. METHODS: Ninety patients with CAP were enrolled in this study. Blood samples of each case were screened for human preformed IgG (HpIgG) antibodies, and stool samples were tested for HpSA and also examined for intestinal parasites by direct wet-mount, formalin-ethyl-acetate concentration, and Trichrome staining procedures. Cellophane tape test was used for Enterobius vermicularis. Children tested positive for HpIgG and/or HpSA were accepted as H. pylori positive. The risk factors were compared with a questionnaire. RESULTS: The incidence of Giardia intestinalis was 14.8% in the H. pylori-positive group and was found to be statistically higher than that in the H. pylori-negative group (1.6%). The positivity rates of H. pylori were found to be statistically higher in children attending school and using drinking water from taps. The incidences of parasitosis were significantly higher in children with a low maternal education level and with a history of parasitosis treatment in the family. CONCLUSION: The most common etiologies of CAP in children are H. pylori infection and intestinal parasitosis. Improvement of hygienic conditions would be beneficial in preventing both infections.

Clarithromycin resistance and 23S rRNA gene point mutations of Helicobacter pylori infection in children.

This study aims to evaluate Helicobacter pylori with clarithromycin resistant genotypes in Manisa region, Turkey. Two hundred patients, who received diagnosis of Helicobacter pylori infection histopathologically, were included. The sex, age and endoscopy indications of the patients were recorded. Polymerase chain reaction method was applied to determine the clarithromycin resistance rate and resistance genotypes at the histologic sections prepared from gastric biopsies that had been embedded in paraffin after fixation by formalin. Helicobacter pylori resistance to clarithromycin was found in 19/200 (9.5%) patients. 10/19 (52.6%) of these clarithromycin-resistant patients had A2143G mutation and 9/19 (47.4%) had A2142G mutation. A2142C mutation on 23S rRNA gene was not detected for any of the patients. Clarithromycin can be used as a first step treatment in the eradication of Helicobacter pylori for the children in our region; if the treatment fails for some patients, clarithromycin resistance, especially A2143G and A2142G mutations should be considered.
