Background: INFLAMMATORY pseudotumor (IPT) is a benign lesion with potential of recurrence and continuous growth. Its clinical and pathologic features resemble malignancies. The present study was conducted in Shaheed Beheshti University of Medical Sciences to determine the status of IPT. Materials and methods: During this descriptive study, the pathology reports of Shaheed Beheshti university teaching hospitals were reviewed from early 1993 to the end of 1998 and 20 cases of INFLAMMATORY pseudotumor were found. Results: The study population included 12 females and 8 males with the mean age of 20 years. 8 cases (40%) were occurred in lung, whereas 12 (60%) were in extra pulmonary regions. 16 had anemia, whereas weight loss and anorexia were reported in 7 cases (35%). Most of the adults had undergone operation with preoperative diagnosis of malignant tumor, however, most of the children received treatment with the probable diagnosis of recurrent pneumonia. Conclusion: Since wide spectrums of benign and malignant tumors are considered as IPT differential diagnosis, suitable preoperative studies such as immunohistochemistry and flowcytometery are highly recommended.

BACKGROUND With an increase in the prevalence and incidence of INFLAMMATORY bowel DISEASES (IBDs), they have become a global challenge. The IBD registry provides complete and timely data, thereby greatly contributing to the estimation of the burden of these DISEASES and development of control and prevention programs. We aimed to develop an IBD registry software. METHODS The present applied-developmental study had two main stages: determining user requirements, and developing the IBD registry software. The software was created using a Web-based software development technology called ASP. NET Core 2. The programming language in this framework was #C, and the SQL Server 2017 was employed to create a strong and integrated software databank in the relational form. RESULTS When determining user requirements, the data elements were classified into two main categories of patient information and visits and tests. Moreover, in this stage, registry functions, including case ascertainment, abstracting, follow-up, quality control, and reporting were identified. In the registry software development stage, the object-oriented conceptual model was designed with five use case diagrams and 59 classes. The user interface comprised the following main sections: add patient, find patient, complete source report, report, staff, and drugs. Precise user authentication and authorization were also employed to enhance the security of the developed software. CONCLUSION Development of an IBD registry which can precisely record patients and estimate the incidence, prevalence, and socioeconomic burden of these DISEASES can assist in planning for the control and prevention of IBD in healthcare systems.
