METHODS Thirty-five patients (20 men,15 women) with inflammatory ulcerative bowel diseases were stud- ied radiographically (barium meal and/or double con- trast study),including:11 cases of tuberculosis,13 Crohn disease,7 bowel Behcet disease,2 simple ulcer and 2 ischemic bowel disease. Diagnosis was estab- lished pathologically in 33 cases and by clinical obser- vation after therapy in 2 cases. RESULTS The lesions were located in ileum,in 9 of 11 cases of TB;in 10 of 13 cases of Crohn disease;in 5 of 7 cases of bowel Behcet disease;in 1 of 2 cases of simple ulcer and in 2 cases of ischemic bowel disease. Ulceration was always present with variable appearances. Longitudinal ulcers,and fissures were noted in Crohn disease only. There were 5 cases of large and deep ulcer and 3 occurred in bowel Behcet disease,10 of 13 cases of superficial and irregular ul- cers were tuberculous,2 cases of transverse ulcer were also tuberculous. CONCLUSIONS The morphologic appearances of the ulcer,surrounding mucosal alterations and bowel deformation were the basis for the radiologic diagnosis. Correct diagnosis was dependent on optimal X-ray ex- amination technique and proper interpretation of the morphologic changes.展开更多

The ischemic cardiovascular disorders (CVD) can be the first health problem of the world. It seems that there is a relationship between pulp stones and cardiovascular diseases to determine the diagnostic value of panoramic dental radiographs as non-invasive test for the early detection of CVD. Methods and Materials: The subjects of the study came from patients presenting to Dental Radiology Department of Dental School in Yazd who aged 30 - 64 years, had 8 natural teeth. They were referred to the Cardiovascular Center of Afshar Hospital in Yazd for cardiovascular evaluation. To set the cut-off point, the ratio of teeth with pulp stones to the total number of teeth for each person was calculated and also ABI for diagnosing IHD via ROC curve was used. Results: Only 3.8% of patients without pulp stone were affected by ischemic heart disease (IHD). About Sixty seven percent (67.3%) of individuals had at least one tooth with pulp stone. In individuals without IHD, 5% of the teeth showed pulp stone while this rate was 45% (9 times) in CVD patients. The number of patients for whom the ratio of teeth with pulp stone to total number of teeth was 0.2 or more, was 138.7 times greater than the other. Conclusion: The dentists, who order panoramic radiographs for the treatment of patients, exactly study those teeth for the presence of pulp stones. The ratio of teeth with pulp stone to total teeth equal 0.2 or more was a good tool for early detection of CVD.展开更多

Interpretation of radiologic signsof cardiogenic pulmonary edema are often question-able and subject. For a bedside prompt evaluation,lung ultrasound(LUS) may assess pulmonary conges-tion through the evaluation of vertical reverberationartifacts, known as B-lines. These artifacts are relatedto multiple minimal acoustic interfaces between smallwater-rich structures and alveolar air, as it happens incase of thickened interlobular septa due to increase of extravascular lung water. The number, diffusion and in-tensity of B lines correlates with both the radiologic andinvasive estimate of extravascular lung water. The inte-gration of conventional chest radiograph with LUS canbe very helpful to obtain the correct diagnosis. Com-puted tomography(CT) is of limited use in the work upof cardiogenic pulmonary edema, due to its high cost,little use in the emergencies and radiation exposure.However, a deep knowledge of CT signs of pulmonaryedema is crucial when other similar pulmonary condi-tions may occasionally be in the differential diagnosis.展开更多
