Wilkie's syndrome admitted for acute abdomen: A case presentation.

Superior mesenteric artery syndrome, also known as Wilkie's Syndrome, is a life threatening clinical entity which developes as a result of obstructed second or third part of duodenum compressed between aorta and superior mesenteric artery. In this rare syndrome, a rapid weight loss is accompanied by stomach ache, abdominal distension, lack of appetite, nausea and vomiting after meals. In patients admitted for acute abdomen, superior mesenteric artery syndrome should be included in the differential diagnosis in case of a preceeding rapid weight loss. X-ray of barium passage, abdominal ultrasound, gastroscopy, abdominal angio-tomography or abdominal magnetic resonance angiography may be useful for diagnosis. Conservative and surgical approaches are available for the treatment. In this report we aimed to emphasize that superior mesenteric artery syndrome cases may admit for acute abdomen and that superior mesenteric artery syndrome should be included in differential diagnosis.

Corrosive Esophagitis with Benzalkonium Chloride in a Two Days Old Neonate.

Benzalkonium chloride (BAC) is a caustic agent which is used in farms, homes and hospitals for cleaning skin and wounds as an antiseptic solution. It may lead to digestive system injuries in case of ingestion. We present a two-days-old newborn case which was carried to the emergency unit with complaints of poor breastfeeding, uneasiness and crying for 4-6 hours. Her mom confessed that she had given a spoon of 10% BAC solution for her cough. Initial laboratory tests were in normal ranges. A gastroscopy performed in the second hour of her admission revealed an hyperemic and edematous mucosa in the middle third of esophagus and a circumferential ulceration followed in the distal portion. Hereupon, a conservative treatment for 10 days was administered and the control gastroscopy demonstrated that the damage was almost totally improved. She was the youngest case with this etiology and successfully treated with conservative approach.

An easy method for diagnosing macro-aspartate aminotransferase: a case series.

Macro-aspartate transaminase (macro-AST) must be considered when the aspartate transaminase (AST) level is chronically high without any liver, cardiac, or muscle disease. Many specialized laboratory techniques have been recommended for diagnosing macro-AST, including the polyethylene glycol immune precipitate technique, which is simple. This study presents a considerably easier method based on the studies of Davidson and Watson and Castiella et al. Our method is based on the decrease in the plasma AST level after storage of the macroenzyme at 2-8 °C for 5 days, and has the advantages of low cost, reliability, and practicality at any health center. In our eight cases of macro-AST, the AST activity at day 6 had decreased by more than 50% from day 1. This method is practical for primary healthcare facilities because of its easy application and accurate results, and obviated the need for unnecessary tests after diagnosis.

Shear wave elastography in the evaluation of liver fibrosis in children.

BACKGROUND: Shear-wave elastography (SWE) is a novel noninvasive method that involves application of local mechanical compression on soft tissue using focused ultrasonography and acquiring strain images that show tissue response. In this study, our goal was to assess the performance of SWE in the staging of liver fibrosis in children with chronic liver disease. METHODS: The study involved measuring SWE values in the right lobe of the liver in a patient group of 76 children with chronic liver disease and a control group of 50 healthy subjects. In the patient group, the shear elastic modulus values were correlated with biopsy results according to the Brunt scoring system (F0: portal fibrosis, F1: perisinusoidal or portal/periportal fibrosis, F2: both perisinusoidal and portal/periportal fibrosis, F3: bridging fibrosis, and F4: cirrhosis). Performance of SWE in estimating liver fibrosis in children was determined based on a receiver-operating characteristics (ROC) analysis. RESULTS: Mean SWE values of the control group and F0 group were not statistically significantly different (P = 0.106). The mean SWE values of the F1, F2, F3, and F4 groups were higher than that of the control group (all P < 0.001). Based on kiloPascal measurement values, the area under the ROC curve was 95.2% (95% confidence interval [CI] 92.1-99.5), with a sensitivity for diagnosing liver fibrosis of 91.5%, a specificity of 94.0%, a positive predictive value of 93.1%, and a negative predictive value of 92.6%. Based on meter-per-second measurement values, the area under the ROC curve was 96.3% (95% CI 92.7-99.8), with a sensitivity for diagnosing liver fibrosis of 93.2%, a specificity of 94.0%, a positive predictive value of 93.2%, and a negative predictive value of 94.0%. Mean SWE values for patients with nonalcoholic steatohepatitis were higher than those in the remainder of the study group. CONCLUSIONS: Although liver fibrosis can be detected using SWE, differentiation of fibrosis stages could not be achieved. The presence of steatosis significantly increased the mean SWE values on elastography and so care should be taken when assessing children with nonalcoholic steatohepatitis.

Association of familial Mediterranean fever in Turkish children with inflammatory bowel disease.

AIM: Familial Mediterranean fever (FMF) and inflammatory bowel disease (IBD) carry similar clinical and biological properties. Both are characterized with chronic inflammation attacks and neutrophil migration and impaired apoptosis mechanism are present in the areas of damage in both conditions. In our study, we aimed to determine the frequency of association of FMF in patients with IBD, to compare the demographic, clinical, laboratory and treatment response properties in these patients with the ones in other IBD patients and to determine association of FMF especially in treatment-resistant patients. MATERIAL AND METHODS: Fifty-three patients who were being followed up with a diagnosis of IBD aged between 0 and 18 years were included in the study. The patient group included the patients who were diagnosed with IBD according to clinical, serological, endoscopic and histopathological criteria, who were being followed up and whose therapies were continuing. Genetic analysis in terms of MEFV gene mutations was performed in all patients with a diagnosis of IBD. Acute phase reactants, complete blood count, immunoglobulin levels, stool analysis, "perinuclear anti-neutrophil cytoplasmic antibodies" (pANCA) and "anti-Saccharomyces cerevisiae antibodies" (ASCA) were studied at the time of diagnosis. The diagnosis of FMF was made according to detailed history, physical examination findings, laboratory tests and the results of genetic analyses in terms of MEFV gene mutations in accordance with the criteria defined in 2009. RESULTS: We found that FMF accompanied in 14 (26.4%) of the patients who had a diagnosis of IBD. 3 of these 14 patients in whom FMF accompanied were being followed up with a diagnosis of Crohn disease and 11 were being followed up with a diagnosis of ulcerative colitis. All of these patients had MEFV gene mutation. These mutations included M694V (50%), K695R (21.4%), M680I (14.3%) and R202Q (14.3%) in order of frequency. When the laboratory data were compared between the patients who had a diagnosis of IBD alone and who had a diagnosis of IBD plus FMF, it was observed that the erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) values were statistically significantly higher in the IBD+FMF group. CONCLUSIONS: FMF is a common condition in the Turkish population and M694V mutation is found most commonly. In our study, this status did not change in cases where FMF accompanied IBD, but K695R mutation was found more frequently compared to FMF alone. We think that it should be kept in mind that other inflammatory conditions including mainly FMF may accompany IBD, if a case of IBD does not have an expected course or is resistant to treatment.

Impact of H. pylori on growth: is the infection or mucosal disease related to growth impairment?

BACKGROUND: Helicobacter pylori (H. pylori) has been recognized as one of the most common chronic bacterial infections in the world. Most children are colonized in early childhood, and the infection will last a lifetime unless the child is treated with appropriate antibiotics. AIM: To evaluate whether H. pylori infection has an influence on growth and whether the severity of endoscopic findings relates to the growth impairment. METHODS: We formed four groups based on the presence or absence of H. pylori infection and gastrointestinal complaints as follows: group I: RAP +/H. pylori+; group II: RAP +/H. pylori-; group III: RAP -/H. pylori+; group IV: RAP -/H. pylori-. The relationship between endoscopic appearances, histological severity of gastritis, and antral H. pylori density with growth parameters was evaluated. RESULTS: The BMI standard derivation scores of groups I and II were significantly lower than those of asymptomatic controls independent of their H. pylori status. A significant difference in height for age standard derivation scores was observed only between groups I and IV. When we compared the BMI and height for age standard derivation scores of group III and group IV combined with that of the endoscopically normal children in the recurrent abdominal pain group, there was no significant difference between the two groups. CONCLUSION: Recurrent abdominal pain associated with gastric mucosal injury plays a role in a decrease in BMI independent of H. pylori infection. However, if recurrent abdominal pain originates from H. pylori infection, it appears that linear growth is also affected.
