A technical note about Phidel: a new software for evaluating magnetic induction field generated by power lines.

The Regional Environment Protection Agency of Friuli Venezia Giulia (ARPA FVG, Italy) has performed an analysis on existing software designed to calculate magnetic induction field generated by power lines. As far as the agency's requirements are concerned the tested programs display some difficulties in the immediate processing of electrical and geometrical data supplied by plant owners, and in certain cases turn out to be inadequate in representing complex configurations of power lines. Phidel, an innovative software, tackles and works out all the above-mentioned problems. Therefore, the obtained results, when compared with those of other programs, are the closest to experimental measurements. The output data can be employed both in the GIS and Excel environments, allowing the immediate overlaying of digital cartography and the determining of the 3 and 10 muT bands, in compliance with the Italian Decree of the President of the Council of Ministers of 8 July 2003.

ELF field in the proximity of complex power line configuration measurement procedures.

The issue of how to measure magnetic induction fields generated by various power line configurations, when there are several power lines that run across the same exposure area, has become a matter of interest and study within the Regional Environment Protection Agency of Friuli Venezia Giulia. In classifying the various power line typologies the definition of double circuit line was given: in this instance the magnetic field is determined by knowing the electrical and geometric parameters of the line. In the case of independent lines instead, the field is undetermined. It is therefore pointed out how, in the latter case, extracting previsional information from a set of measurements of the magnetic field alone is impossible. Making measurements throughout the territory of service has in several cases offered the opportunity to define standard operational procedures.

[Laparoscopic rectopexis].

INTRODUCTION: Rektopexis is an effective treatment method of rectal prolapses. Our retrospective study assessed the laparoscopic rectopexis results. METHODOLOGY: From 01-01-2003 to 31-11-2005, 10 patients were indicated for the procedure of laparoscopic retropexis. A "Vypro" mesh (Johnson&Johnson) was used to suspend the rectum. We fix it to the sacrum and to the rectum with an anchor (Eanchr, Johnson&Johnson). The follow-up examinations were conducted 2-30 months after the procedure. We assessed mortality rates, morbidity rates, the prolaps relapses incidence rates, obstipation incidence rates. RESULTS: The laparoscopic procedure was completed in 9 patients. In one case, we converted. The mortality and serious postoperative morbidity rate was 0%. The mean duration of hospitalization was 7 days. During the follow-up, no patient relapsed. One female patient complained of mild postoperative obstipation, which, however, did not require surgical revision. CONCLUSION: Laparoscopic rectopexis is a modern, safe and effective method of the prolaps of the rectum treatment.

[Diagnosis of mixed psychoses].

The author presents a review of views on so-called "medium or mixed" endogenous psychoses, starting with Kraepelin and Bleuler to the present time, the creation of the term "schizoaffective psychosis (disorder)" in diagnostic classifications. He draws attention to the still persisting influence of Kraepelin-Bleuler diagnostics, incl. their controversial character as regards the classification of so-called "mixed psychoses". Other diagnostic concepts were either completely or are enforced with great difficulties. On the diagnosis of schizoactive psychosis the author demonstrates the changing understanding of its contents and thus also the controversial attitude to the diagnosis in the course of time which was reflected in the development of diagnostic classifications. The paper also comprises the author's study of the frequency of diagnosis of endogenous psychic disorders in the Psychiatric Research Institute (present name Psychiatric Centre Prague) in the course of 29 years. The study indicates that from the sixties the diagnosis of schizoaffective disorder played the role of a buffer between the schizophrenic and manic-depressive area. It helped to solve ranae of the unstable concept of schizophrenia and classification of atypical forms of endogenous psychoses. The study indicates that there exists possibly a closer relation between the schizoaffective disorder and affective disorders than with schizophrenia. In the conclusion the author appreciates the asset of classifications DSM-III and ICD-10 for the definition and differentiation of schizoaffective disorders.

[Development of psychiatric disability in psychotics and their rehabilitation].

The authors describe the results of a 12-month follow up of a group of patients who had an attack of functional psychosis. They paid attention to their professional work, course of the disease and social sequelae of the disease. The authors assessed also predictors of satisfactory future of professional activities by clinical methods as well as by selected psychological tests. They confirmed the effectiveness of aimed rehabilitation and resocialization care in patients with a chronic course of the disease and with residual postpsychotic symptoms.

[Medical informatics and health care in Subotica yesterday, today and tomorrow].

The application of information systems in health care throughout the world has begun ten years after the first generation of computers. Computers are a tool for doing business in all segments of health care. After a presentation of the development of informatics in the world and in our surroundings, a survey of events related to the health-care informatics in Subotica is given, as well as the perspective which is expected.

Hydrazide-functionalized poly(2-hydroxyethyl methacrylate) microspheres for immobilization of horseradish peroxidase.

Nonporous cross-linked poly(2-hydroxyethyl methacrylate-co-ethylene dimethacrylate) (poly(HEMA-co-EDMA)) microspheres were prepared by dispersion polymerization of HEMA and EDMA. The polymerization was performed in toluene/2-methylpropan-1-ol in the presence of cellulose acetate butyrate as a steric stabilizer and dibenzoyl peroxide initiator. The particle size may be increased by decreasing the toluene/2-methylpropan-1-ol ratio and by increasing polymerization temperature. Adipohydrazide was attached to the microspheres activated with 2,4,6-trichloro-1,3,5-triazine. After periodate oxidation of its carbohydrate moieties, horseradish peroxidase was coupled to the hydrazide-functionalized poly(HEMA-co-EDMA) microparticles up to 7.3 microgram of enzyme/g of carrier without a significant loss of its activity. Immobilized peroxidase was found to be stable, retaining more than 97% of its initial activity when stored for 23 days after the preparation.
