Abstract
BackgroundFunctional exercise capacity might be affected in ankylosing spondylitis (AS) patients due to factors such as pulmonary function impairment, reduced physical activity, peripheral arthritis, fatigue, muscle weakness and systemic inflammation. In addition to laboratory-based exercise tests, field tests are also used to measure functional exercise capacity. The six-minute walk test (6MWT) which is the most frequently used field test, is valid, reliable, and cost-effective. However, the main disadvantage of the 6MWT is that it allows the patient to set the walking speed. The incremental shuttle walk test (ISWT) is a valid field exercise test of functional capacity. The test requires patients to walk at increasing speeds up and down a 10 m course. The walking speed, which increases every minute, is controlled by audio signals. Performance on the test relates strongly to VO2max, the traditional indicator of cardiorespiratory capacity [1]. Although there are studies evaluating functional exercise capacity in AS patients, no study using ISWT has been found.ObjectivesThe aim of this study was to investigate the ISWT results and factors associated with this test in patients with AS.MethodsFifty AS patients aged between 25-58 years (27 males,23 females,) participated in the study. Age, height, weight, body mass index (BMI) were recorded. Disease-specific indices such as Bath AS Disease Activity Index (BASDAI), Bath AS Functional Index (BASFI), Bath AS Metrology Index (BASMI) were used. Sit-up test and push-up test were used to measure muscular endurance. Incremental Shuttle Walk Test (ISWT) was used to assess functional exercise capacity The test was performed in a 10 m course defined by two cones placed 0.5 m from each endpoint. The test was terminated if the patient was unable to maintain the required speed and failed to complete a shuttle in the time allowed for the second time. The total number of shuttles was recorded and distance calculated. Heart rate (HR), blood pressure, perceived dyspnea and leg fatigue (modified Borg Scale) were assessed before and after the test. Age-predicted maximal heart rate (HRmax) was calculated as 220 minus age. Spearman’s correlation coefficients were used to examine the relationship between the ISWT distance and the variables.ResultsThe mean incremental shuttle walk distance (ISWD) of the patients was 458.40± 98.63 m (min 290 m-max 710 m). Subjects reached 50% of the predicted ISWD according to the reference equation for healthy people [2]. The maximal heart rates were lower than predicted values anticipated for the patients’ age. At the end of the test, subjects reached 57.97±8.62 % of HRmax. ISWD showed significant correlations (p<0.05) with gender (r = 0.488), height (r = 0.474), BASFI (r = -0.313), BASMI (r = -0.397), sit-up test (r = 0.620), push-up test(r = 0.476). However, no relationship was found between ISWD and age, weight, BMI, BASDAI, dyspnea, fatique. Dyspnea and fatigue were not limiting factors for the test. The most common reason for stopping the test was the inability of the patients to maintain the set pace. ISWD has been reported to be associated with age [2], but in our study, unlike the literature, no relationship was found between ISWD and age in AS patients.ConclusionAccording to the results of our study, we found that the incremetal shuttle walk test distance in AS patients decreased compared to the reference values reported for healthy individuals. ISWT is associated with factors such as gender, height, functionality, spinal mobility and muscular endurance. ISWT may be appropriate for measuring exercise capacity of AS patients, however, more research is needed.References[1]Singh S, Morgan M, Hardman A, Rowe C, Bardsley P (1994) Comparison of oxygen uptake during a conventional treadmill test and the shuttle walking test in chronic airflow limitation.

Abstract
Thrombophilia is a rare but potentially catastrophic phenomenon occurring in patients having tendency of thrombosis. It may lead to serious complications. The etiology of thrombophilia is thought to be multifactorial and related to both acquired and inherited factors. Inflammatory bowel disease is an acquired cause of thrombophilia. Thromboembolic events are seen during inflammatory bowel disease, especially during the active period of the disease. In inflammatory bowel disease, thrombus formation in portal, splenic and mesenteric veins are not common. Besides, the association of genetic disorders related to metabolism of homocysteine with inflammatory bowel disease has been evidenced, especially in Crohn disease and rarely in ulcerative colitis. We present a rare case of ulcerative colitis in association with combined portal, splenic and mesenteric vein thrombosis. The patient was recently diagnosed with the disease which was in the inactive period. Interestingly, our patient was also heterozygous for the mutation in methylenetetrahydrofolate reductase (MTHFR) gene.

Abstract
Hepatitis A virus infection is usually a self-limited disease during childhood. Autoimmune manifestations are rarely reported among patients. We describe two children with acute hepatitis A infection who developed immune thrombocytopenia and hepatic venous thrombosis during the course of acute infection. Antiphospholipid antibodies were increased in both of them during the thrombocytopenic and thrombotic complications and decreased during the resolution of these events.

Abstract
Blue rubber bleb nevus syndrome is a rare disorder characterized by distinctive cutaneous and gastrointestinal venous malformations that usually cause massive or occult gastrointestinal hemorrhage and iron deficiency anemia secondary to the bleeding episodes. It is even a rare cause of gastrointestinal hemorrhage during childhood. We describe a 6-year-old boy who had multiple venous malformations all over his body. He also suffered from several episodes of melena, chronic anemia, and growth retardation. The endoscopic examination of the gastrointestinal tract revealed multiple bluish-black sessile and polypoid venous malformations in various sizes. It was possible to remove the largest venous malformations causing massive bleeding during colonoscopy.

Abstract
Congenital microvillus atrophy is a severe generalized enteropathy with ultrastructural abnormalities of the intestinal brush border. It is a rather new clinicopathological entity which needs to be differentiated from other enteropathies within the spectrum of intractable diarrhea of infancy. The presented case was a four-month-old girl with a chronic, intractable diarrhea, beginning at birth. The diagnosis was established only after the electron microscopic examination of small intestinal mucosa which revealed the characteristic features of the disease. Congenital microvillus atrophy is a rare autosomal recessively inherited disorder and bowel transplantation becomes a realistic option of treatment. Therefore, it should be specifically considered in the differential diagnosis of chronic intractable diarrhea of infancy.

Abstract
In a prospective clinical study, 64 patients with gastric pathologies (27 malignant and 37 benign) were examined ultrasonographically. Gastric wall layer changes, gastric wall thickness, lesion length, and protrusion into the lumen were evaluated. A scoring system was defined based on the distribution of these parameters and the score of each patient was calculated retrospectively. Six of the malignant cases had scores in the benign range and 3 of the benign cases had scores in the malignant range. Sensitivity of this scoring system in terms of detecting malignancy was 78% and specificity 92%. The positive predictive value was 88%, the negative predictive value was 85%, and overall diagnostic accuracy was 86%. This scoring system was considered to be a useful aid in the differential diagnosis of gastric pathologies.
