[Histamine liberation in extracorporeal circulation].

Extra-corporeal circulation (E.C.C.) has been held responsible for histamine liberation incidents, essentially by a mechanical cause. In order to prove this, the authors assayed the overall histaminaemia at different times during E.C.C. in 11 patients. The results are discussed in terms of the patients' backgrounds, temperature, hematocrit, blood gases and the acid-base balance, and electrolyte balance. Histaminaemia, corrected depending on the dilution, did not show any significant variation, even in two patients who clinically had anaphylactic manifestations.

A search tool based on 'encapsulated' MeSH thesaurus to retrieve quality health resources on the internet.

In the year 2001, the Internet has become a major source of health information for the health professional and the Netizen. The objective of Doc' CISMeF (D'C) was to create a powerful generic search tool based on a structured information model which 'encapsulates' the MeSH thesaurus to index and retrieve quality health resources on the Internet. To index resources, D'C uses four sections in its information model: 'meta-term', keyword, subheading, and resource type. Two search options are available: simple and advanced. The simple search requires the end-user to input a single term or expression. If this term belongs to the D'C information structure model, it will be exploded. If not, a full-text search is performed. In the advanced search, complex searches are possible combining Boolean operators with meta-terms, keywords, subheadings and resource types. D'C uses two standard tools for organising information: the MeSH thesaurus and the Dublin Core metadata format. Resources included in D'C are described according to the following elements: title, author or creator, subject and keywords, description, publishers, date, resource type, format, identifier, and language.

Cost effectiveness of a medical digital library.

The rapid increase in the price of electronic journals has made the optimization of collection management an urgent task. As there is currently no standard procedure for the evaluation of this problem, we applied the Reading Factor (RF), an electronically computed indicator used for consultation of individual articles. The aim of our study was to assess the cost effective impact of modifications in our digital library (i.e. change of access from the Intranet to the Internet or change in editorial policy). The digital OVID library at Rouen University Hospital continues to be cost-effective in comparison with the interlibrary loan costs. Moreover, when electronic versions are offered alongside a limited amount of interlibrary loans, a reduction in library costs was observed.

[CISMeF: catalog and index of French-speaking medical sites].

The Internet has now become a major source of health information. The aim of CISMeF is to catalogue and index the main French-speaking sites and documents concerning health. This project was initiated by Rouen University Hospital. Its URL is http://www.chu-rouen.fr/cismef. CISMeF covers all areas of health care and medical sciences, and is indexed both alphabetically and according to subject. It was set up on a Sun workstation under the Sun UNIX operating system and is entirely based on static HTML. By May 1999, the number of sites and documents indexed was already over 6,500, with a mean of 75 new sites added each week. CISMeF is updated via a five-step process: resource collection, filtering, description, classification, and indexing. The Net Scoring criteria are used to assess the quality of health information on the Internet. These criteria concern eight categories: credibility, content, links, design, interactivity, quantitative aspects, ethics and accessibility. CISMeF uses two standard tools to organize information: the MeSH (medical subject heading) thesaurus from the Medline reference database (National Library of Medicine, USA) and the Dublin core metadata format. The sites and documents included in CISMeF are described using the following elements from the Dublin core project: title, author or creator, subject and keywords, description, publisher, date, resource type, format, identifier, and language.

[Oculorespiratory reflex].

The lack of interest about oculorespiratory reflex (ORR) in surgery and experimental studies is obvious. However the authors insist on the importance of its clinical traduction. The purpose of this study is to determinate an experimental model with titration of stimulus (pressure or traction) and therapeutic test. Our first Results prove the clinic entity of O.R.R. In first conclusion, we can insist on the importance of ventilatory assistance during squint surgery and on the monitoring of PE CO2 and Sa O2.

[A new anesthetic protocol in experimental ocular surgery in rabbits].

The authors describe a new anaesthetic protocol for laboratory rabbits. The surgery consists in an extracapsular lens extraction with intraocular lens implantation in the bag. The anaesthetic protocol requires: an intravenous induction with ketamine (20.2 mg/kg +/- 5) and midazolam (0.65 mg/kg +/- 0.3) and after an oral endotracheal intubation with a simple method, and at last maintaining halothane anaesthesia with a concentration between 3 and 4%. 45 anaesthesia were performed: the average time of the anaesthesia was 77 min +/- 16. No rabbit died because of this anaesthesia. The anaesthesia was a success for the surgeon who could operate in the best working conditions.
