Clinical efficacy of N-acetyl-aspartyl-glutamic acid nasal spray in children suffering from pollinosis: a double-blind multicentre study.

A double-blind, four-centre study was carried out in 66 children to compare the clinical efficacy and safety of N-acetyl-aspartyl-glutamic acid (NAAGA) and disodium cromoglycate (DSCG) nasal sprays. At similar dosage conditions (one puff per nostril, four times daily, for 3 weeks), no significant differences between the treatments were discernible in the primary efficacy parameters (scores, patients' and physicians' opinion). Both products induced statistically significant improvements in the nasal, ocular and total scores, but not in the respiratory (breathing) score. The hay-fever symptoms improved clinically in > 50% of the children after only two weeks with both treatments. The exact figures depended on the parameters considered. Thirteen out of 25 patients (52%) in the NAAGA group found the efficacy "good" or "excellent" at the end of the treatment period; the corresponding opinion in the DSCG group was expressed by 10 out of 24 patients (41.7%). Of the 28 patients that used the rescue medication, 12 (42.8%) were from the NAAGA group and 16 (57.1%) from the DSCG group. One patient on NAAGA treatment reported side effects, i.e. pruritus in the nose and sneezing.

HIPIN--a generic HIS/RIS-PACS interface based on clinical radiodiagnostic procedures.

Within the EurIPACS HIPIN topic a generic HIS/RIS-PACS interface will be designed, implemented and evaluated. It is generally agreed that integration with the HIS/RIS is essential for the acceptance of PACS in a clinical environment. An interface between HIS/RIS and PACS allows more efficient usage of both systems, better integration of data, better consistency checking on shared data and better security and error handling. Also the PACS performance is improved by using HIS/RIS information to steer the image migration within the PACS. In this paper the functional specifications of the interface are described. These specifications are based on descriptions of clinical radiodiagnostic procedures. The generic interface consists of a common part, and of site specific adapters. The common part is identical for all incarnations and performs message scheduling, processing and logging. The adapters are specific for each communication standard, e.g. ACR-NEMA or HL7, and for each hospital. The interface will be implemented at the radiology department of the Philipps University Hospital in Marburg (Germany) and at the orthopaedic and neuroradiology departments of the hospital of the Free University in Brussels (Belgium).

Overview of CAPACITY data.

This paper presents an overview of the data from 15 cases collected with the CAPACITY software for cost analysis of PACS. The data suggest that both hospital wide and partial PACS implementations do not pay back yet. Only Nuclear Medicine PACS systems may be introduced cost-neutral in the near future. Because of the assumed price drop of hardware components of 5-25% per year, hospital wide and partial PACS may allow cost savings within the next 10-20 years. There are major differences in viewpoints concerning the required PACS configurations and their costs. The experiences with the CAPACITY software suggest the need for the establishment of key rules, for designing a PACS configuration and for estimating PACS costs.

PACER: a software tool for PACS decision makers.

This paper describes the development of the software package PACER as it evolved from a cost model to a software package for PACS decision making. PACER was developed as part of the TEASS topic from the EurIPACS project. EurIPACS is an EU subsidized project covering a wide area of PACS related research. The TEASS topic concerns the evaluation of prototype PACSystems in three European hospitals. PACER allows the user to evaluate costs of various PACS implementation scenarios and compare them to the costs of the current film based situation. Its cost calculation is based on a straight forward description of costs of a film based radiology department and of PACS. The PACER cost analysis can consider stepwise introduction of PACS and a corresponding stepwise disappearance of the film environment. This analysis includes effects of price developments. PACER calculates costs and expenses for a number of years in succession. The calculated results can be analysed using graphs, tables and sensitivity analysis tools. Preliminary tests in three hospitals indicate that PACER can indeed be a useful tool in the decision process concerning PACS.
