Co-existence of Gastrointestinal Stromal Tumors with Malign Epithelial Tumors: a Report of Two Cases
O. Firat P. Yazici O. Makay A. Aydin M. Tuncyurek S. Ersin 《Acta chirurgica Belgica》2013,113(5):629-632
Aim: To emphasize the importance of a detailed observation for incidental simultaneous tumoral masses during surgery for gastrointestinal stromal tumors (GISTs) at any location in the gastrointestinal system. Case presentations: Case 1: a 39 years old female patient with an esophageal squamous cell carcinoma and a synchronous small intestinal GIST discovered incidentally during esophagectomy.Case 2: a 73 years old female patient with a gastric GIST and a synchronous colorectal cancer detected incidentally during gastrectomy. In both cases, immunohistochemical examinations of the resected specimens confirmed the coexistences of GISTs and epithelial malignancies.Conclusion: The coexistences of GISTs with epithelial tumors have been increasing in recent years. In any case of a GIST or gastrointestinal adenocarcinoma, the surgeon should be alert to recognize a possible coexistent tumor with different histological origin. 相似文献

Atherosclerotic plaques tend to involve arterial localizations in which blood flow is not laminar due to arterial bends and bifurcations. A 49-year-old man was admitted to hospital with breathlessness and was subsequently diagnosed with left ventricular failure. Coronary angiography revealed three-vessel coronary artery disease and an anomalous extra left anterior descending artery taking off from the right sinus of Valsalva and spared from atherosclerosis. The absence of side branches and the relative lack of bends in arterial geometry were considered to be the cause of resistance to atherosclerosis. The present case identifies local flow conditions as an important factor determining the genesis of atherosclerosis in arterial segments. 相似文献

Introduction
This study evaluated the cyclic fatigue resistance (CFR) of Reciproc (R25 and R40; VDW, Munich, Germany) and Reciproc Blue (R25 and R40, VDW) instruments used in an artificial S-shaped canal.Methods
A total of 80 files were tested in an S-shaped canal (n = 20 for each file, Reciproc R25 and R40 and Reciproc Blue R25 and R40). This study compared Reciproc R25 with Reciproc Blue R25 files and Reciproc R40 with Reciproc Blue R40 files. All files were rotated in an S-shaped artificial canal until fracture. CFR was determined by recording the time to fracture in the artificial canal. The length of each fractured fragment was measured in millimeters. An independent sample t test was used to analyze the data.Results
Between the R25 files, Reciproc Blue instruments showed significantly greater CFR than the Reciproc files in the apical and coronal curves (P < .05). Between the R40 files, Reciproc Blue instruments exhibited greater CFR in the apical and coronal curves (P < .05). There was no difference in the fractured fragment lengths of the Reciproc Blue files compared with the Reciproc files (P > .05).Conclusions
The Reciproc Blue R25 and R40 files showed greater CFR than the Reciproc R25 and R40 files in an S-shaped canal. 相似文献84.

Background
The aim of this current report is to present an unusual case of a maxillary ameloblastoma mimicking an oroantral fistula.Case report
A left subtotal maxillectomy via Weber–Ferguson-type incision was performed. The patient tolerated the procedure well, the postoperative course was uneventful, and the patient was discharged 3 days after surgery with a mild paraesthesia of the right infraorbital nerve distribution. The infraorbital nerve paraesthesia has resolved 5 months after resection. The patient has been followed-up for 3 years without recurrence.Discussion
Ameloblastoma is a well-known pathology of the maxillofacial region. However, unusual manifestations of this tumor can represent a serious challenge for diagnosis. 相似文献85.

The purpose of the current study was to compare the characteristics of lung cancer patients who had exposure to asbestos and asbestos-related radiological findings (ARRF) to the characteristics of patients who had no exposure. Of the 766 lung cancer patients evaluated, 607 had no exposure to asbestos and no ARRF, 88 had ARRF and a history of exposure, remaining 71 patients had no exposure to asbestos occupationally and no ARRF, but we could not obtain environmental exposure history from them. So we excluded these 71 patients' data. The study patients were compared with respect to age, gender, smoking history, duration and nature of symptoms, findings on physical examination, tumor histological types, chest X-ray (CXR) findings, tumor site and stage, and survival. Lung cancer patients with ARRF were more often males, former smokers, and older than patients with no history of exposure to asbestos. There were no differences between the groups of patients in terms of the duration of symptoms, the distribution of symptoms, the findings on physical examination, tumor histological type, and the CXR findings. There was no difference between the two groups of patients in the distribution among tumor stages and median survival. The anatomic site of origin of the tumor in the group with ARRF was peripheral and in the lower zone of the lung. We suggest that specific attention should be given to the peripheral and lower zones of the lungs on CRX during the evaluation of the patients with ARRF for lung cancer. 相似文献

[Purpose] To describe the functional consequences of patients with cardiac diseases and
analyze associations between activity limitations and quality of life. [Subjects and
Methods] Seventy subjects (mean age: 60.1±12.0 years) were being treated by Physical
Medicine and Rehabilitation and Cardiology Departments were included in the study.
Activity limitations and participation restrictions as perceived by the individual were
measured by the Canadian Occupational Performance Measure (COPM). The Nottingham Extended
Activities of Daily Living (NEADL) Scale was used to describe limitations in daily living
activities. To detect the impact of activity limitations on quality of life the Nottingham
Health Profile (NHP) was used. [Results] The subjects described 46 different types of
problematic activities. The five most identified problems were walking (45.7%), climbing
up the stairs (41.4%), bathing (30%), dressing (28.6%) and outings (27.1%). The
associations between COPM performance score with all subgroups of NEADL and NHP; total,
energy, physical abilities subgroups, were statistically significant. [Conclusion] Our
results showed that patients with cardiac diseases reported problems with a wide range of
activities, and that also quality of life may be affected by activities of daily living.
COPM can be provided as a patient-focused outcome measure, and it may be a useful tool for
identifying those problems.Key words: Activity limitation, Cardiac diseases, Quality of life 相似文献

Objective
The aim of this research was to assess the relationship between mitral annular calcification (MAC) and whole blood viscosity (WBV).Subjects and Methods
A total of 184 patients with MAC and 133 patients without MAC were enrolled in the study. The WBV was calculated with a confirmed formulation using the hematocrit and total plasma protein at a low shear rate (LSR) and high shear rate (HSR). Early diastolic mitral annular velocity (Ea) and late diastolic mitral annular velocity (Aa) were measured using pulse Doppler tissue echocardiography. Pearson''s correlation analysis was performed to assess the relationship between WBV and mitral annular motion velocities. The effects of different variables on the occurrence of MAC were assessed in univariate and multivariate logistic regression analysis.Results
In patients with MAC, WBV values were significantly higher at HSR (18.04 ± 0.84 vs. 17.25 ± 0.96 208 s-1, p < 0.001) and at LSR (78.0 ± 14.2 vs. 61.9 ± 17.1 0.5 s-1, p < 0.001). The WBV at HSR and LSR were significantly correlated with Ea (r = −0.477, p < 0.001; r = −0.385, p < 0.001, respectively) and Aa (r = −0.544, p < 0.001; r = −0.323, p < 0.001, respectively). Multivariate analysis showed that WBV of both shear rates was an independent predictor of MAC. Using the ROC curve, a cut-off value of 70.1 for WBV at LSR had a sensitivity of 83.7% and a specificity of 73.7% (AUC 0.785, p < 0.001) and a WBV cut-off value of 17.5 at HSR had a sensitivity of 79.6% and a specificity of 71.4% (AUC 0.761, p < 0.001) for the prediction of MAC.Conclusion
Patients with MAC had significantly higher WBV, which independently predicted the presence of MAC. WBV had an inverse correlation with mitral annular motion velocities, indicating that a higher WBV may lead to greater limitation in annular motion and, thus, more calcification.Key Words: Mitral valve calcification, Shear stress, Blood viscosity 相似文献89.

Liver penetration is a rare complication of peptic ulcer disease. Histopathological examination of endoscopic biopsy is essential for diagnosis as well as sonographic and computerized tomography imaging. Endoscopic examination could not exclude tumor without pathologic examination. Herein, we report a patient diagnosed as duodenal ulcer penetration into liver by endoscopic biopsy. 相似文献

A field evaluation of a new area repellent system, Thermacell Mosquito Repellent (TMR, cis-trans allethrin), was conducted against phlebotomine sand flies and mosquitoes in Cunpolat village, Sanliurfa Province, in southeastern Anatolia, Turkey, an area historically endemic for cutaneous leishmaniasis and high sand fly populations. The objective of this study was to determine the efficacy, duration of protection, and spatial characteristics of protection (downwind distance from point of release), of the TMR. Twelve adult volunteers (nine in the treatment and three controls) made collections from ankle to knee for 25 min every hour from 2100 to 0300 on six consecutive nights in August 2002. Treatment consisted of placing a TMR unit at the middle of the village and then placing human bait collectors at 2.3, 4.6, and 7.6 m away from the repellent unit. Results from the field tests showed highly significant protection provided by the TMR from attack by Phlebotomus papatasi (Scopoli) (P < 0.001) and Ochlerotatus caspius (Pallas) (P < 0.001) for up to 4 h postapplication. In the six nights that tests were done, a total of 949 sand flies and 1095 mosquitoes were collected from the untreated control sites. Only 86 sand flies and 83 mosquitoes were collected at all distances from the places treated with TMR. These results indicated that reduction in sand fly and mosquito biting rates in treated groups ranged from 87.5 to 97.7% (mean protection 92%) and 90.2-97.4% (mean protection 93%), respectively. The percentage reduction values were maintained above 90.0% for 6 h of the assessment period. Overall, the number of bites by the cutaneous leishmaniasis vector Ph. papatasi and also Oc. caspius was reduced > 11-fold and 13-fold, respectively, by the TMR. 相似文献
