1041. Cerebral hyperperfusion syndrome after carotid angioplastyZoran Miloševič, Bojana Žvan, Marjan Zaletel, Miloš Šurlan, 2002, published scientific conference contribution Abstract: Background. Cerebral hyperperfusion syndrome after carotid endarterectomy is an uncommon but well-de- fined entity. There are only few reports of "hyperperfusion injury" following carotid angioplasty. Case report. We report an unstable arterial hypertension and high grade carotid stenosis in a 58-year-old, right-handed woman. After a stroke in the territory of middle cerebral artery carotid angioplasty was per- formed in the patient. Among riskfactors, the long lasting arterial hypertension was the most pronounced. Immediately after the procedure, the patient was stable without any additionalneurologic deficit. The sec- ond day, the patient had an epileptic seizure and CT revealed a small haemorrhage in the left frontal lobe. Conclusions. The combination of a high grade carotid stenosis and unstable arterial pressure is probably an important prognostic factor in the pathogenesis of hyperperfusion syndrome.

1043. European project BRAPHYQSJanez Burger, 2002, professional article Abstract: Background. Quality assurance in radiotherapy and brachytherapy is extremely important because errors that may occur during treatment process can be fatal for the patient. European Society for Therapeutic Radiology and Oncology has therefore founded BRAPHYQS, a special group that is responsible for the revision of quality assurance procedures of treatment performed in brachytherapy centers and for outlining common standards of work in European countries. Conclusions. The project BRAPHYQS has the following aims: (1) to publish European recommendations for implementing QA/QC in European brachytherapy centers; (2) to set up a central dosimetry audit in European brachytherapy centers (this task will be delegated to ESTRO-EQUAL laboratory at the Institute Gustave Roussy in Paris); (3) to set up a central audit for the geometrical reconstruction of source positions with a special test phantomthat will be available to each brachytherapy center. Hence, a series of"Baltas phantoms" will be elaborated and distributed to the brachytherapy centers in Europe; (4) to prepare a draft of booklet of QA/QC recommendations for testing the brachytherapy equipment and therapy planning systems.

1044. Effects of 5-Gy irradiation on fertility and mating behaviour of Nezara viridula (Heteroptera: Pentatomidae)Alenka Žunič Kosi, Andrej Čokl, Gregor Serša, 2002, original scientific article Abstract: Background. The polyphagous and cosmopolitan species Nezara viridula is one ofthe most important insect pests. The sterile insect technique (SIT) is a pest control strategy that involves sterilising males by exposing them to ionising radiation. Sterile males, released into wild population, mate with females, but eggs are not fertilised and the population gradually declines. Exposing insects to radiation during their growth stage might require lower sterilising dose. The aim of our study was to test whether 5-Gy irradiation of5th instar nymphs significantly affects: (1) moulting and further development of the irradiated nymphs, (2) the male's and female's reproduetivesystem and (3) the mating competitiveness of treated males, with special focus on vibrational communication. Methods: The 5th instar nymphs were irradiated with 5 Gy using X ray generator and monitored daily. Results: The observed effects of irradiation were: prolonged moulting increased mortality during development and during the first day of adult life, decreasedmales to females ratio, decreased fecundity, egg production, proportion of fertile eggs and progeny survival. The reaction of a male to stimulation with the model female calling song was tested. The irradiated and non-irradiated males responded to stimulation with emission of the eourtship song (MCrS). Temporal parameters of MCrS emitted by non-irradiated males differed when compared with those of irradiated ones. Conclusions: The 5-Gy irradiation of 5th instar nymphs did not affect mating behaviour. However since the irradiation during growth stage decreased the fertility and fecundity of emerged adults, this technique, in combination with certain othersuppression teehniques, could be a successful control strategy for management of Nezara viridula. On the other hand observed effects on moulting and further development of the irradiated nymphs could decrease the efficiencyand application of this strategy.

1045. Extramedullary plasmacytoma of the larynx : a report of three casesPrimož Strojan, 2002, other scientific articles Abstract: Purpose. To report three cases of extramedullary plasmacytoma of the larynx treated at the Institute of Oncology in Ljubljana between 1969-1999. Results. All three patients were treated with radiotherapy only, whieh resulted in permanent local and regional control of 7.8, 4.7 and 3.5 years. The funetion of the larynx was preserved in all of them. Two patients died, both to the causes other than plasmacytoma. In none of the patients disease progressed to multiple rnyeloma. Conclusions. Extramedullary plasmacytoma of the larynx is arare disease, highly curable when radiotherapy is used. Moderate radiation doses and limited fields ensure excellent cosmetic and funetional result.

1048. Warm mix asphalt use in Slovenia and in Europe : a reviewPrimož Pavšič, 2022, review article Abstract: Recently, we have witnessed an extreme increase in the prices of energy and raw materials, on the one hand, and economic expansion, due to the business growth in construction sector, part of which is also the asphalt industry, on the other hand. The asphalt industry in particular is facing increasing challenges of economic acceptability and reducing greenhouse gas emissions, as well as improving working conditions. One of the possible solutions proved to be warm mix asphalts (WMA), which can be produced and compacted at reduced temperatures in comparison to hot mix asphalt (HMA). The beginnings of WMA technology in Europe date back to 1999, while in Slovenia the first field test was conducted in 2005. In the last two decades a numerous research and studies on the properties and technologies of WMA production have been conducted. According to EAPA (European Asphalt Pavement Association), the use of WMA cumulatively in Europe in period from 2013 to 2020 is slowly increasing, but the differences in WMA production in individual European countries are significant. The article presents an overview of WMA production techniques, their advantages and disadvantages and their usage in individual European countries in comparison to Slovenia.
