Irritable Bowel Syndrome on Inflammatory Bowel Disease in Deep Remission: No Relation with Remission Deepening and Inflammation.

BACKGROUND: The aim of the study was to establish the frequency of irritable bowel syndrome (IBS) in patients with inflammatory bowel disease (IBD) in clinical, endoscopic, and histologic remission and in relation to both the depth of remission and inflammation markers. METHODS: Patients with ulcerative colitis (UC) and with Crohn's disease (CD) in clinical remission for at least 6 months were enrolled in the study. All of the patients underwent colonoscopy, and biopsy specimens were taken to evaluate endoscopic and histopathologic remission. Patients were evaluated according to Rome III criteria for IBS. Fecal calprotectin level and blood samples for C-reactive protein (CRP), sedimentation rate, and fibrinogen levels were studied. RESULTS: IBS frequency was 20.9% in UC cases and 28.9% in CD cases in clinical remission. Rates with and without endoscopic remission in UC (20.5% vs. 22.2%, P = .727) and CD (25% vs. 33.3%, P = .837, respectively) were not different. Similarly, rates with and without histopathologic remission in UC (15.7% vs. 26.6%, P = .723), and CD (21.4% vs. 33.3%, P = .999) were not statistically different. Also, it was not related to inflammation markers. CONCLUSION: IBS frequency among IBD patients with remission was in a substantial rate; these rates kept up with the process of deep remission and even complete mucosal healing and were irrelevant to inflammation.

Perifosine and vitamin D combination induces apoptotic and non-apoptotic cell death in endometrial cancer cells.

Endometrial cancer is the most common cancer of the female reproductive system. Combination treatment with specific agents has been widely used as a targeted therapy for cancer. In this study, we aimed to investigate the anti-proliferative and apoptotic effects of varying concentrations of perifosine and vitamin D on the human endometrial cancer cell line (HEC-1A). HEC-1A cells were exposed to perifosine (10 µM, 30 µM), vitamin D (50 nM, 200 nM) and combinations of both for 48 h and 72 h. Monitoring of cell proliferation in a time-dependent manner was performed with the xCELLigence RTCA DP system. The levels of BCL2, BAX and P53 mRNA expression were examined using RT-qPCR. Apoptosis was determined using Annexin V, which were followed by flow cytometry analysis. Ultra-structural morphology of cells was analyzed by transmission electron microscopy (TEM) for 72 h. The anti-proliferative and apoptotic effects of the perifosine+vitamin D combination (30 µM + 200 nM at 48 h and 10 µM + 200 nM at 72 h) on HEC-1A cells were higher than in perifosine and vitamin D alone. It was observed that perifosine has increased the expression of BAX mRNA in HEC-1A cells in a dose-dependent manner. While perifosine+vitamin D combinations increased P53 mRNA expression in HEC-1A cells we did not find any significant change in BCL2, BAX mRNA expression levels. In TEM examinations of HEC-1A cells, perifosine appeared to lead autophagic cell death, whereas vitamin D caused paraptosis-like cell death and combination of perifosine+vitamin D caused apoptotic and non-apoptotic (paraptotic, autophagic and necrotic) cell death. Therefore, it is considered that the combination of both drugs in the treatment of endometrial cancer might be an alternative and effective treatment option through activating the apoptotic and non-apoptotic cell death mechanisms in cancer cells.

Anatomic Variations of Paranasal Region in Migraine.

PURPOSE: To assess the incidence of anatomical variations of the paranasal region on computed tomography in migraine patients compared with control subjects. METHODS: Paranasal computed tomography scans of 2 groups consisting of 50 migraine patients and 50 control subjects were evaluated, retrospectively. The presence of anatomic variations and the unilateral or bilateral presence of these variations were noted. Appropriate statistical tests were performed to compare the migraine and control groups, using a threshold P value of 0.05 for statistical significance. RESULTS: The migraine group included 39 female and 11 male patients with mean age of 39.9 (range: 18-65) years. The control subject group included 29 female and 21 male patients with mean age of 41.9 (range: 18-73) years. Anatomic variations noted included nasal septal deviation and spur, paradoxical curvature of middle concha, agger nasi cell, infraorbital ethmoidal (Haller) cells, sphenoethmoidal (Onodi) cells, supraorbital ethmoidal air cells, concha bullosa, uncinate bulla, and pneumatized crista galli. Of these variations, only the presence of Haller cells was statistically significantly higher in the migraine group compared with controls (P = 0.007). The unilateral presence of Onodi (P < 0.001), unilateral presence of supraorbital ethmoidal air cells (P = 0.012), and bilateral presence of concha bullosa (P = 0.016) were statistically significantly higher in the migraine group. There was no statistically significant difference between the unilateral or bilateral presence of Haller cells in migraine patients compared with controls (P > 0.05). CONCLUSION: Radiographic assessment of the paranasal sinuses is useful to elucidate potential points of pathology in migraine patients. The specific contribution of Haller cells to migraine headache symptoms and safe methods for surgical decompression warrant further study.
