Introduction: the detection of gastric preneoplastic lesions (atrophic gastritis, intestinal metaplasia, dysplasia) is important regarding the patient's risk evaluation for gastric cancer. The purpose of this study consists in the pit pattern evaluation, specific to the 3 premalignant lesions by magnifying endoscopy and chromeondoscopy. Material and methods: The study has started in January 2010 and it is still in progress. The patients have been examined by conventional endoscopy, respectively selected for magnifying endoscopy and chromoendoscopy. Partial results: I have obtained pit patterns specific to gastric mucosa in precancerous lesions. Partial conclusions: 1. Several pit patterns can be identified in the same patient. 2. The stomach can be mapped more exactly, this way being identified the area of modified mucosa; thus target biopsies can be done raising the chances for an accurate diagnosis. 3. It is a resource and time-consuming method. [ABSTRACT FROM AUTHOR]

Introduction: Surgery has an important role in the curative therapy of gastric cancer along with multimodal strategies. The paper aims to highlight the advantages of using the LigaSure devices (LigaSure Atlas 20 cm and LigaSure Small Jaw) in performing "en bloc " subtotal gastrectomy and lymphadenectomy. Materials and methods: We present the case of a 48 year old patient admitted in the Surgical Clinic 1, Emergency County Hospital Târgu Mureş, with a diagnosis of antral gastric cancer. We performed a subtotal gastric resection (4/5) without using ligatures, and "en bloc" D1 lymphadenectomy, using for hemostasis and lymphodissection LigaSure devices (LigaSure Atlas 20cm, LigaSure Small Jaw). Results: The postoperative radiologic control showed anastomotic complex functionality. The patient's postoperative evolution was favourable and the histopathological findings confirmed the diagnosis of undifferentiated antropyloric gastric carcinoma(pT3N2). Conclusions: The advantages of using LigaSure devices in gastric cancer surgery are: D1 and "extended" D1 lymphadenectomy, efficient haemostasis and lymphostasis, subtotal gastric resection and "en bloc" lymphadenectomy.

Healthcare Information Systems (HIS) generally rely on large databases that store medical data. Apart from the specific issues related to the design of the data structures, these systems present a challenge to the developer regarding the architecture of the external level of the database, closely related to the building of the user interface. This paper discusses three specific issues related to the user interface of a medical database (The Temporal Property, The Allocation Process and The Open Attribute List Specialization) using a data-oriented approach for the external level. The approach is mostly based on data views, constructed on the server side and on the client application side. A small number of stored procedures however is necessary to implement the full functionality of the system. In our approach, most of the complexity of these processes is embedded in the queries that are run against the database. These queries can often be complex and time consuming. Two major issues arise from here: first, complexity can lead to inconsistent presentation of the same data (we are considering large information systems) and second, large queries can severely affect overall performance. These are the factors which the designers of such a system must control in order to reach an acceptable balance. By using the presented techniques, software developers can easily build user interfaces that present basic or medium-complex functionality, while having the benefits of standardization. For highly complex functionality, more advanced patterns and technologies are needed, which will be presented in a future paper. [ABSTRACT FROM AUTHOR]

In our past work, we have developed a data structuring technique based on trees and multitrees to model clinical research data. In this paper, we try to assess the suitability of this model for keeping an electronic laboratory notebook by comparing its strengths and weaknesses with the products of some of the leading software providers on the market. The comparison focuses on five critical aspects: customizability, the use of tree-like structures, the use of patterns or templates, the techniques used to retrieve the data and functions that support collaboration. In the last two sections of the paper, we discuss our findings and draw some conclusions that will serve as guidelines for our future work. [ABSTRACT FROM AUTHOR]
