Background: Abdominal tuberculosis, the sixth commonest extrapulmanory tuberculosis, is easily misdiagnosed due to nonspecific gastrointestinal symptoms. The diagnosis is highly dependent on clinician’s suspicion of the disease; therefore to increase awareness we retrospectively reviewed clinical features of eight children in a four year-period. Methods: The medical records of children with abdominal TB were retrospectively reviewed. The diagnosis of abdominal TB was defined as Mycobacterium tuberculosis infection of gastrointestinal tract along with peritoneal or solid organ involvement. Results: There were six girls and two boys with a mean age of 13.6 ± 2.8 years (range, 7 - 16 years). Abdominal pain and weight loss were common complaints in all patients (100%) at presentation; fever was present in four (50%) patients and abdominal distension in two (25%) patients. Mean duration of symptoms before diagnosis was 2.5 ± 1 months. Laparotomy performed in six patients, and the peritoneum was the most common infection site (in 5 patients). Chest X-rays of 7 patients indicated lung involvement. The most common abdominal computed tomography and ultrasonography finding was ascites. Bowel wall thickening was recorded in 2 patients and ileal thickening in 1 patient. Inguinal lymphadenopathy and multiple mesenteric lymphadenitis were present as single cases. Conclusions: The abdominal tuberculosis should be suspected in children with ongoing abdominal pain, fever, and abdominal distension, laparoscopy or laparotomy could be useful in the differential diagnosis and utilizing imaging techniques, invasive methods with clinical suspicion may prevent delay of the diagnosis.

Background: Celiac disease is an autoimmune disorder characterized by damage to the small intestinal mucosa following the intake of gluten-containing foods in genetically predisposed individuals. Studies suggest that celiac disease is associated with asthma and allergic rhinitis. Objectives: The aim of this study was to examine the prevalence of asthma and allergic rhinitis in children with celiac disease compared to healthy controls. Methods: This study was conducted in 53 celiac children and 80 children with nonspecific abdominal pain as a control group; all participants were between 6 - 19 years. The children completed the ISAAC questionnaire, and spirometry was performed in each participant. Results: The prevalence rates of asthma symptoms and physician-diagnosed asthma were similar in both groups (30% and 19%, respectively, in the celiac group and 17.5% and 22.5%, respectively, in the control group) (P > 0.05). Six (11%) patients with celiac disease and seven (9%) children in the control group showed obstructive changes on pulmonary function tests. The prevalence rates of allergic rhinitis symptoms and physician-diagnosed allergic rhinitis were also similar in both groups (36% and 9%, respectively, in the celiac group, and 34% and 9%, respectively, in the control group) (P > 0.05). Conclusions: The prevalence rates of asthma and allergic rhinitis in patients with celiac disease were not significantly higher when compared to the healthy controls. [ABSTRACT FROM AUTHOR]

Abstract  Mesalazine is a first-line drug in pediatric inflammatory bowel disease, and is effective as primary treatment and maintenance therapy. It’s usually well tolerated, but various side effects have been described. A 15-year-old female with ulcerative colitis developed polyuria, polydipsia, vomiting, and fatigue. She was receiving mesalazine (500 mg, thrice daily, p.o.) and prednisolone for 4 months. She was detected as acute tubular injury as she had dehydration, acidosis, hypostenuria, hematuria, proteinuria, low levels of potassium, uric acid and bicarbonate. These findings were attributed to interstitial nephritis as a side effect of mesalazine, however as renal biopsy was disapproved by the parents, it was not confirmed. After discontinuation of mesalazine her renal tubular functions improved. Potassium and phosphorus supplements were stopped after 7 months, although she had to continue bicarbonate supplementation. We conclude that regular renal screening is important in patients receiving 5-ASA therapy to prevent rare but serious complications, such as interstitial nephritis sometimes leading to chronic renal failure.

Aim: To evaluate the agreement of multichannel intraluminal impedance-pH monitoring (MII-pHM) and gastroesophageal reflux scintigraphy (GES) for the diagnosis of gastroesophageal reflux disease., Methods: Seventy-five consecutive patients with suspected gastroesophageal reflux disease (GERD) underwent 24-h combined MII-pHM recording and one hour radionuclide scintigraphy during the course of the MII-pHM study. Catheters with 6 impedance channels and 1 pH sensor were placed transnasally. Impedance and pH data analysis were performed automatically and manually. For impedance monitoring, reflux was defined as a retrograde 50% drop in impedance, starting distally and propagating retrogradely to at least the next two more proximal measuring channels. Reflux index (RI, percentage of the entire record that esophageal pH is < 4.0) greater than 4.2% for pHM and number of refluxes more than 50 for 24 h for MII were accepted as positive test results. At scintigraphy, 240 frames of 15 seconds duration were acquired in the supine position. Gastroesophageal reflux was defined as at least one reflux episode in the esophagus. After scintigraphic evaluation, impedance-pH recordings and scintigraphic images were evaluated together and agreement between tests were evaluated with Cohen's kappa., Results: Sufficient data was obtained from 60 (80%) patients (34 male, 56.7%) with a mean age of 8.7 ± 3.7 years (range: 2.5-17.3 years; median: 8.5 years). Chronic cough, nausea, regurgitation and vomiting were the most frequent symptoms. The mean time for recording of MII-pHM was 22.8 ± 2.4 h (range: 16-30 h; median: 22.7 h). At least one test was positive in 57 (95%) patients. According to diagnostic criteria, GERD was diagnosed in 34 (57.7%), 44 (73.3%), 47 (78.3%) and 51 (85%) patients by means of pHM, MII, GES and MII-pHM, respectively. The observed percentage agreements/κ values for GES and pHM, GES and MII, GES and MII-pHM, and MII and pHM are 48.3%/-0.118; 61.7%/-0.042; 73.3%/0.116 and 60%/0.147, respectively. There was no or slight agreement between GES and pHM alone, MII alone or MII-pHM. pH monitoring alone missed 17 patients compared to combined MII-pHM. The addition of MII to pH monitoring increased the diagnosis rate by 50%., Conclusion: No or slight agreement was found among pH monitoring, MII monitoring, MII-pH monitoring and GES for the diagnosis of gastroesophageal reflux disease., Competing Interests: Conflict-of-interest statement: There are no potential conflicts of interest for any of the authors.
