Item Fecal calprotectin levels in Helicobacter pylori gastritis in children(2020) Aksoy, Ozlem Yuksel; Canan, Oguz; Hosnut, Ferda Ozbay; Akcay, EdaYilmaz; Ozcay, Figen; 0000-0003-0614-4497; 0000-0002-5214-516X; 33372437; AAI-9386-2021; ABG-5684-2020Background. Fecal calprotectin is an important inflammatory marker in intestinal diseases and is not routinely used in the upper gastrointestinal system disorders. The aim of this study was to show whether there is a relationship between fecal calprotectin levels and Helicobacter pylori (H pylori) gastritis in children and to determine the association of fecal calprotectin levels with gastric biopsy results in terms of chronic inflammation and neutrophil activity. Methods. Patients with the complaints of the upper gastrointestinal system (epigastric pain, heartburn, nausea and vomiting) who were planned to undergo endoscopy were enrolled prospectively. The presence of H pylori was defined according to the gastric antrum biopsy results. Fecal calprotectin level was tested in the stool sample of the patients. The fecal calprotectin levels, upper gastrointestinal endoscopy and gastric biopsy results of 89 patients were evaluated. Results. H pylori was found to be positive in the gastric biopsies of 51 (57.3%) patients. In the H pylori positive group mean fecal calprotectin level was 74.8 +/- 67 mu g/g, and in the H pylori negative group mean fecal calprotectin level was 52.7 +/- 46 mu g/g and the difference was significant (p= 0.039). We also found a significant relationship between fecal calprotectin levels and gastric neutrophil activity grades (p= 0.034). Conclusions. Mean fecal calprotectin levels were found to be higher in H pylori positive subjects in our study. Fecal calprotectin levels were correlated with gastric neutrophil activity grades. Fecal calprotectin represents gastric neutrophilic inflammation. When interpreting a high fecal calprotectin level, H pylori infection should be kept in mind.Item Percutaneous endoscopic gastrostomy experience in children and family satisfaction(2019) Canan, OguzPurpose: The aim of this study was to evaluate the demographic data, complication rates of children who underwent percutaneous endoscopic gastrostomy (PEG) and to question family satisfaction. Materials and Methods: Demographic information, underlying diseases, anthropometric measurements before and after PEG and z scores advanced complications due to processing and follow-up periods were obtained from patient files. Results: In three years, 21 patients underwent PEG procedures. The median age of the patients was 74 months. The majority of the cases consisted of children with neurological, oncological and metabolic diseases (71.4%, 14.3% and 14.3%, respectively). There was a statistically significant increase between baseline and 6th month and between baseline and 12th month of the all antropometric measures z scores. But no significant difference was observed between 6th month and 12th month of the median weight and height z scores. Parents' opinions about PEG were positive. After the procedure, one patient had ostomy leakage and three patients had local stoma infection. Conclusion: Percutaneous endoscopic gastrostomy is a very successful and reliable method in children and adolescents as well as in infants. Families' opinions on PEG after the procedure were positive.Item Intractable Diarrhea from Cytomegalovirus Colitis in a Case with Hereditary Spherocytosis(2015) Ozkale, Murat; Canan, Oguz; Asilsoy, Suna; Bal, Nebil; Noyan, AytulCytomegalovirus (CMV) infection is a common viral infection worldwide, with a frequency as high as 90% in developing countries. Only 10% of primary CMV infection is symptomatic in immunocompetent patients, and it rarely causes specific complications. We report CMV colitis in an immunocompetent adolescent with hereditary spherocytosis and spontaneous rupture of the spleen, who was critically ill with septicaemia and significant non-bloody diarrhoea that responded to specific CMV treatment.Item Does bee pollen cause to eosinophilic gastroenteropathy?(2015) Guc, Belgin Usta; Asilsoy, Suna; Canan, Oguz; Kayaselcuk, Fazilet; 26568697Bee pollen is given to children by mothers in order to strengthen their immune systems. There are no studies related with the side effects of bee polen in the literature. In this article, the literature was reviewed by presenting a case of allergic eosinophilic gastropathy related with bee polen. A 5-year old child was admitted due to abdominal pain. Edema was detected on the eyelids and pretibial region. In laboratory investigations, pathology was not detected in terms of hepatic and renal causes that would explain the protein loss of the patient diagnosed with hypoproteinemia and hypoalbuminemia. Urticaria was detected during the follow-up visit. When the history of the patient was deepened, it was learned that bee pollen was given to the patient every day. The total eosinophil count was found to be 1 800/mm(3). Allergic gastroenteropathy was considered because of hypereosinophilia and severe abdominal pain and endoscopy was performed. Biopsy revealed abundant eosinophils in the whole gastric mucosa. A diagnosis of allergic eosinophilic gastropathy was made. Bee polen was discontinued. Abdominal pain and edema disappeared in five days. Four weeks later, the levels of serum albumin and total eosinophil returned to normal.Item Etiologies, outcomes, and prognostic factors of pediatric acute liver failure: A single center's experience in Turkey(2016) Ozcay, Figen; Karadag-Oncel, Eda; Baris, Zeren; Canan, Oguz; Moray, Gokhan; Haneral, Mehmet; 0000-0003-2498-7287; 0000-0002-3462-7632; 0000-0002-5214-516X; 0000-0003-0614-4497; 27782894; AAE-1041-2021; AAJ-8097-2021; ABG-5684-2020; AAB-4153-2020; AAI-9386-2021Background/Aims: Our aim was to determine the etiologies, outcomes, and prognostic indicators in children with acute liver failure. Materials and Methods: Ninety-one patients who were followed for pediatric acute liver failure (PALF) over a 15-year period were included. Patients who survived with supportive therapy were designated as Group 1, while those who died or underwent liver transplantation were designated as Group 2. Results: There were 37 (40.6%) patients in Group 1 (spontaneous recovery) and 54 (59.4%) patients in Group 2. Thirty-two patients (35.2%) underwent liver transplantation. Infectious and indeterminate causes were the most common etiologies (33% each). Among the infectious causes, hepatitis A (76%) was the most frequent. Hepatic encephalopathy grade 3-4 on admission and during follow-up and high Pediatric Risk of Mortality (PRISM) and Pediatric End-Stage Liver Disease (PELD) scores within the first 24 h were related with a poor prognosis. Group 2 had a more prolonged prothrombin time, higher international normalized ratio, more prolonged activated partial thromboplastin time (aPTT), and higher levels of total and direct bilirubin, ammonia, and lactate (for all, p<0.01). Conclusion: Infectious and indeterminate cases constituted the most common etiology of PALF, and the etiology was related to the prognosis in our series. Although high PELD and PRISM scores were related to poor prognoses, no sharp thresholds for individual laboratory tests could be elucidated. Liver transplantation was the only curative treatment for patients with poor prognoses and resulted in high survival rates (1-, 5-, and 10-year survival rates of 81.3%, 81.3%, and 75%, respectively) in our study.Item Bocavirus Viremia and Hepatitis in an Immunocompetent Child(2017) Canan, Oguz; Haytoglu, Zeliha; 0000-0003-0614-4497; 28443581; AAI-9386-2021Background: So far, many studies have shown that Human Bocavirus (HBoV) is the main pathogen of the respiratory tract. Until now, there is no study that proves the association between HBoV and hepatitis. HBoV viremia/DNAemia has been associated closely with acute primary infection and moderate-to-severe illness but, more detailed clinical data about HBoV dissemination are still unavailable. Case Report: Here we report a 2-years-5-months-old girl suffering from respiratory distress and heptitis followed in our intensive care unit. HBoV was detected in our patients nose and throat swabs concurrent with whole blood sample by positive polymerase chain reactions. After a through investigation no causative agent other than HBoV viremia was found. Conclusion: Human Bocavirus viremia with high viral loads may be associated with hepatitis.Item Duodenitis caused by Sarcina ventriculi in a case with Celiac disease and selective IgA deficiency(2017) Canan, Oguz; Ozkale, Murat; Kayaselcuk, Fazilet; 0000-0002-1180-3840; 0000-0003-0625-1057; 0000-0003-0614-4497; AAE-2550-2021; A-7806-2016; AAI-9386-2021Sarcina ventriculi is a gram-positive, obligate anaerobic bacteria first documented in the human gastrointestinal tract in 1842. Sarcina ventriculi are found to be associated with delayed gastric emptying and gastric outlet obstruction Up to date numerous cases of fatal disease have been attributed to this organism in the veterinary literature, but only a few human cases have been documented. Herein we report a case of a 10-year-old girl patient who was diagnosed Celiac disease, selective IgA deficiency and Sarcina ventriculi duodenitis. To the best of our knowledge the association Celiac disease and Sarcina ventriculi duodenitis has not been previously reported in children. Therefore, in the present study we want to draw attention to the importance of a rare coexistance of Celiac disease and Sarcina ventriculi duodenitis.
